Adherence and attrition with intermittent and continuous exercise in overweight women.

Few people are active to the levels recommended by Healthy People 2010. Intermittent exercise has been promoted as an exercise prescription which may enable more people to meet recommended guidelines. However, few data are available on intermittent exercise over the long-term. The purpose of the current study was to compare the effects of long-term (72 weeks) continuous (CON) and intermittent (INT) exercise on attrition and adherence in previously sedentary, moderately obese females. Participants were randomized to continuous walking at 60 to 75% of maximum aerobic capacity, 3 days per week, 30 minutes per session, or intermittent exercise for two 15-minute sessions, 5 days per week. Adherence was calculated as the number of sessions completed compared to the number of sessions prescribed. At 12-week intervals, attrition was calculated as the number of participants in the study compared to the total number of participants originally enrolled. For the participants who completed the study, body weight decreased for CON from 80.17 +/- 5.75 kg at baseline to 79.70 +/- 5.40 at 16 months (p < 0.05). For INT, body weight did not change from baseline (85.85 +/- 13.13 kg) to 16 months (85.05 +/- 12.90 kg). By design, INT walked significantly (p < 0.05) further (819 +/- 128 km) compared to CON (527 +/- 46 km). Attrition was 58% for both groups baseline to 72 weeks. However, attrition was greater for CON (38 %) compared to INT (16%) in the first 24 weeks. Adherence was excellent for both groups (> 83%) throughout the study. These results suggest that intermittent and continuous exercise both have considerable attrition rates within 72 weeks of exercise initiation; however, the pattern of attrition differs considerably. That is, it appears that intermittent exercise may reduce attrition in the first 24 weeks of an exercise program; however, attrition does not appear to be different than continuous exercise at 72 weeks.

[Treatment of overweight. Use of a program].

This article publicizes the results of an overweight treatment program carried out as a working model under the auspices of Primary Health Care. This program placed special emphasis on educational aspects, preventive as well as promoting healthy ways of living; and one in which activities planned towards establishing means of conduct which play a direct role in their users health factors are focused on. This treatment program occurred as a group activity. The 27 participating subjects, 23 women and 4 men, were recommended by their doctor/nurse. Their average age was 37.6 years, +/- 11.3. 19 subjects were overweight with an IMC between 25 and 30; the other 8 had been diagnosed as obese with an IMC over 30. This program took place in the Health Center meeting hall over 4 months, from February through June. Among the elements of this program, these deserve special mention: the use of a vocabulary exempt of adverse connotations, for example, instead of diet we spoke of menus; the establishment of behavioral goals before weight loss goals; the practice of elaborating and designing hypercaloric menus; providing positive reinforcement for those behaviors which increased the level of physical activity which was objectively measured by means of podometers; the practice of eating slowly; etc. At the end of the program, the results showed an average weight loss of 4.2 kilograms, a range of 0.9 to 6.12 K, with respect to the average weight at the start of the program. One can foresee that this loss will continue to occur, especially in those cases where the subject had modified some habits such as eating rapidly or performing physical exercise related to overweightness. These results are open to discussion regarding the efficiency of the program and with regards to this program as an example of a coordinated effort between the Mental Health Unit and a Primary Health Care Team in relation to the design and implementation of health programs directed towards the attention of people with overweight problems.

Preventive home visits postpone mortality--a controlled trial with time-limited results.

BACKGROUND: There is a debate on whether preventive home visits to older people have any impact. This study was undertaken to investigate whether preventive home visits by professional health workers to older persons can postpone mortality in a Swedish context. METHOD: A controlled trial in a small community in the north of Sweden. Participants are healthy pensioners aged 75 years and over. 196 pensioners were selected as the intervention group and 346 as the control group. The intervention, two visits per year, lasted two years. RESULTS: During the intervention, mortality was 27 per 1000 in the intervention group and 48 per 1000 in the control group. The incidence rate ratio for the control group IR2000-2001 was 1.79 (95% CI = 0.94-3.40). Analysing the data with an "on treatment approach" gave a significant result, 2.31 (95% CI = 1.07-5.02) After the trial the difference between the groups disappeared. CONCLUSION: Preventive home visits in a healthy older population can postpone mortality in a Swedish context if they are carried out by professional health-workers in a structured way. When the home visit programme ended the effect on mortality disappeared. These findings are dependent on contextual factors that make it difficult to form general policy recommendations.

Attitudes and practices of families and health care personnel toward children with epilepsy in Kilifi, Kenya.

PURPOSE: Epilepsy is common in underresourced countries, where most people with epilepsy do not take antiepileptic drugs (AEDs). This underutilization, referred to as the treatment gap, was investigated in Kilifi, Kenya, by exploring the sociocultural context in which children with epilepsy and their families live. This study focused particularly on what effect attitudes and practices might have on service utilization, particularly the use of AEDs. METHODS: Attitudes and practices toward children with epilepsy were examined using qualitative data collection methods, namely, interviews, focus group discussions, group activities, and observations. These were carried out with children diagnosed as having active epilepsy, their parents, their grandparents, and health care personnel. RESULTS: The responses illustrate both positive and negative attitudes, underpinning a wide variety of practices toward children with epilepsy. They also indicate the use of several types of services that vary between the traditional, medical, educational, and religious. The choice of these services was affected by different socioeconomic factors, the complex interrelationship of which offers some explanation for the underutilization of AEDs. CONCLUSIONS: The treatment gap may be explained by a "health versus sickness" model, accounting for families' health-seeking behavior in relation to their perception of cause and treatment. In this model, occasional convulsions associated with fever in younger children are placed in the "health sphere," making recommendations of regular and continued medication illogical for what is perceived to be a healthy child. When seizures persist beyond a certain age, the child is placed in the "sickness sphere," meaning that the child is incurable and treatment attempts are futile. Better levels of understanding and information sharing among children with epilepsy, their families, and health care personnel are required to improve use of medical services. Possible interventions include community-based services and health education programs for the community and service providers.

Induced termination of pregnancy before and after Roe v Wade. Trends in the mortality and morbidity of women. Council on Scientific Affairs, American Medical Association.

The mortality and morbidity of women who terminated their pregnancy before the 1973 Supreme Court decision in Roe v Wade are compared with post-Roe v Wade mortality and morbidity. Mortality data before 1973 are from the National Center for Health Statistics; data from 1973 through 1985 are from the Centers for Disease Control and The Alan Guttmacher Institute. Trends in serious abortion-related complications between 1970 and 1990 are based on data from the Joint Program for the Study of Abortion and from the National Abortion Federation. Deaths from illegally induced abortion declined between 1940 and 1972 in part because of the introduction of antibiotics to manage sepsis and the widespread use of effective contraceptives. Deaths from legal abortion declined fivefold between 1973 and 1985 (from 3.3 deaths to 0.4 death per 100,000 procedures), reflecting increased physician education and skills, improvements in medical technology, and, notably, the earlier termination of pregnancy. The risk of death from legal abortion is higher among minority women and women over the age of 35 years, and increases with gestational age. Legal-abortion mortality between 1979 and 1985 was 0.6 death per 100,000 procedures, more than 10 times lower than the 9.1 maternal deaths per 100,000 live births between 1979 and 1986. Serious complications from legal abortion are rare. Most women who have a single abortion with vacuum aspiration experience few if any subsequent problems getting pregnant or having healthy children. Less is known about the effects of multiple abortions on future fecundity. Adverse emotional reactions to abortion are rare; most women experience relief and reduced depression and distress.

The -1997 G/T polymorphism in the COLIA1 upstream regulatory region is associated with hip bone mineral density (BMD) in Chinese nuclear families.

Type I collagen is the most abundant protein of bone matrix, and the collagen type I alpha 1(COLIA1) gene has been considered one of the most important candidate genes for osteoporosis. In this study, we simultaneously tested linkage and/or association of the -1997 G/T polymorphism in the COLIA1 upstream regulatory region with the variation of bone mineral density (BMD) in 1263 subjects from 402 Chinese nuclear families, consisted of both parents and at least one healthy female offspring from 20 to 45 years of age. All the subjects were genotyped by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). BMD of the lumbar spine (L1-L4) and hip (respective and combined phenotype of the femoral neck, trochanter, and intertrochanter) was measured by dual-energy X-ray absorptiometry (DXA). By using the tests implemented in program QTDT (quantitative transmission disequilibrium test), we found significant within-family association (via TDT) between the -1997 G/T polymorphism with BMD variation at all the hip sites (respective and combined phenotypes, P < 0.05). The amount of BMD variation explained by the -1997G/T polymorphism was 1.6%, 2.0%, 1.2%, and 1.3% at the total hip, femoral neck, trochanter, and intertrochanter, respectively. Because of the limited number of sib pairs in this sample, we did not find evidence of linkage. In summary, the -1997 G/T polymorphism in the COLIA1 gene is likely to be in linkage disequilibrium with a nearby functional polymorphism affecting hip BMD, or the -1997 G/T polymorphism itself may have an important effect on the variation of hip BMD in our Chinese sample.

[Efficient prevention of overweight and obesity in the experience of family practitioners and "nutrition units" of the public health system in Lombardy].

General practitioners (GP's) presence is homogeneously distributed in the Lombardy territory. GP's are easy accessible by people so they could play a key role in the prevention of overweight and obesity. In this study GP's included in everyday medical activity a primary prevention strategy regarding nutrition and lifestyle. The goal was to maintain a constant BMI for one and a half year for at least 50% of the patients (stable means without progression within BMI's range). During the same time another endpoint was to decrease from 1 to 3 units the BMI in overweight patients in half of the observed population. Subjects were randomly recruited during routinely ambulatory activity, without a specific BMI based selection. Diet quality was assessed with a food frequency questionnaire regarding "protective foods" as vegetables, fruits and legumes. Some "basic" information about nutrition and lifestyle where then provided through explanation of issues printed on A4 page brochure. Percentage BMI's range variation before and after the intervention show a stability in the observed population, with an increase 0,3% for normal weight males and 0,9% for females. BMI was constant in 72,2% of the subjects considering a 1 unit variation and in 92,2% considering 3 units variation. Within subjects who varied 1 unit (27,7%) more subjects decreased rather than gained weight (16% vs 11,7%); within subjects who varied 3 units (7.8%), 4,5% decreased and 3,3 increased their BMI. GP's demonstrate to have an efficient role in weight gain control with a simple and regular prevention strategy towards healthy lifestyles and simple nutritional tips. It is important for patients to comprehend the importance the doctor give to the overweight and obesity problem, apart from the medical issue considered during the visit. GP's have a key role for healthy life-style change programs among their patients. These results provide new arguments about the opportunity to invest public resources towards population (managed in collaboration with GP's coordinated by a public health department such as NU), rather than towards a single patient. The project management was supervised by the Nutrition Unit (NU) of the public heath system SIAN (ASL di Brescia).

Diseases of meaning, manifestations of health, and metaphor.

Disease and health are commonly thought of as distinct opposites. We propose a different view in which both may be seen to be facets of healthy functioning, each necessary for the other, each giving rise to the other. Thus, disease may be thought of as a manifestation of health. It is the healthy response of an organism striving to maintain physical, psychologic, and spiritual equilibrium. Disease is not necessarily to be avoided, blocked, or suppressed. Rather, it should be understood to be a process of transformation. The process should therefore be facilitated because it is an integral part of the dynamic equilibrium that we ordinarily think of as health. In many cases, perhaps all, people get ill because there is something going "wrong" in their lives. This could occur in a whole range of ways-relationships, environment, food, or job. Our view, however, is that disease is a meaningful state that can inform health workers how to help patients to heal themselves. In this way, instead of being meaningless, people's problems become diseases of meaning, enabling people to see that things are not necessarily "going wrong" but are, in fact, helping them become stronger, to live more fully and with more understanding. Seen from this perspective, depression; cancer; heart disease; neurodegenerative and autoimmune disease; dementia; and conditions such as community violence, genocide, and the problem of environmental devastation are "diseases of meaning." World Health Organization forecasts make it clear that diseases of meaning will continue well into the next millennium to be the major cause of suffering and death worldwide. To deal with them, the world needs to reformulate the biomolecular paradigm that has been exploited in the last two centuries. It does not address the reasons why these diseases arise, attending mainly to their molecular consequences. A paradigm that includes the importance of meaning must now be given top priority. The concept that diseases are a manifestation of health-a call to a different relationship with ourselves and our environment, both animate and inanimate- is in itself a different approach. Programs for care and education based upon it would have immediate application in medicine, industry, education and ecology. We believe that this model would have far-reaching consequences for the understanding, treatment, and prevention of diseases and behaviors that lead to violence and environmental destruction.

Population pharmacokinetics of ibandronate in Caucasian and Japanese healthy males and postmenopausal females.

INTRODUCTION: Ibandronate is a potent, nitrogen-containing bisphosphonate that is licensed as a once-monthly oral preparation and is currently in clinical development as a novel intermittent intravenous (i.v.) injection in osteoporosis. Ibandronate pharmacokinetic (PK) data were used to develop a PK model that could ultimately be incorporated into a PK pharmacodynamic (PD) model to assist the ibandronate development program through computer-assisted trial design. This manuscript reports the use of non-linear mixed-effects modeling to characterize the PK of ibandronate, to examine the possible influence of ethnicity on the disposition of ibandronate and to develop an appropriate population PK model for ibandronate. METHODS: A retrospective, cross-study population PK analysis was performed using PK data from five phase I studies with i.v. ibandronate (0.125 - 2.0 mg) conducted in Caucasian and Japanese healthy male volunteers, postmenopausal Caucasian women without osteopenia and postmenopausal Japanese women with osteopenia. The following covariates were investigated to establish their influence on the central volume of distribution (V1) and drug clearance (CL): age, body weight, gender, disease status (healthy versus osteopenic), creatinine clearance (CLCR), and ethnicity (Japanese versus Caucasian). Serum concentrations of ibandronate were quantified by GC-MS or ELISA, and data were modeled using non-linear mixed-effects modeling implemented by the software program NONMEM. RESULTS: The PK of ibandronate was adequately described by a linear 3-compartment model. Disease status, body weight, gender and CLCR significantly influenced ibandronate CL (10 34%) and the latter 3 also influenced V1 (20 29%). Ethnicity was not a determinant for ibandronate PK in the final model. Although gender was the most influential covariate, differences in V1 and CL between the sexes were modest (29 and 34%, respectively) and the overall effects on ibandronate exposure (Cmax and AUC) were not clinically relevant. The final model described the observed PK of ibandronate well, and all PK parameters were estimated with an acceptable degree of precision (SE < 13%). CONCLUSION: The PK of i.v. ibandronate was well described by a linear 3-compartment population PK model that included disease status, body weight, gender and CLCR as covariates, but without greatly affecting ibandronate exposure (Cmax and AUC). Ethnicity did not influence ibandronate PK and was not included in the final model.

Results of go girls: a weight control program for overweight African-American adolescent females.

OBJECTIVE: Go Girls was a church-based nutrition and physical activity program designed for overweight African-American (AA) adolescent females. RESEARCH METHODS AND PROCEDURES: Ten predominantly middle-socioeconomic churches were randomized to either a high-intensity (20 to 26 sessions) or moderate-intensity (six sessions) culturally tailored behavioral group intervention delivered over 6 months. Each session included an experiential behavioral activity, approximately 30 minutes of physical activity, and preparation and tasting of healthy foods. In the high-intensity group, girls also received four to six telephone counseling calls. From the 10 churches, 123 girls completed baseline and 6-month post-test assessments. The primary outcome was BMI; secondary outcomes included waist and hip circumferences, percentage body fat estimated by bioimpedance, serum insulin, glucose, and lipids, and cardiovascular fitness at 6-month follow-up. Selected measures were also collected at 1-year follow-up. RESULTS: At 6-month follow-up, the net difference between the high- and moderate-intensity groups was 0.5 BMI units. This difference was not statistically significant (p = 0.20). There were no significant group differences in secondary outcomes. Girls in the high-intensity condition, however, who attended more than three-quarters of the sessions had significantly lower BMI and percentage body fat relative to girls in the high-intensity group who attended fewer sessions. Findings at 1-year follow-up mirrored those at 6 months. DISCUSSION: We concluded that the intervention was not effective in reducing adiposity, although there were some positive findings among high attenders. Despite the null result, the intervention was generally well received by participants. Future interventions may require greater dose and a more structured dietary change program.

New tools for learning.

In the last twenty-five years more has been learned about the human brain than in the past history of mankind. Through the use of new technologies such as PET and CAT scans and functional MRI's, it is now possible to see and learn much about the human brain while it is in the process of thinking. The research of neuroscientists, such as Marian Diamond, has demonstrated that the brain changes physiologically as a result of learning and experience--for better or worse--and that plasticity can continue throughout the lifespan. It appears that there are particular kinds of environments that are most conducive to the development of good mental equipment. They are positive, nurturing, stimulating, and encourage action and interaction. Many of the most effective schools and training programs have created such high-challenge low-threat environments. It is also very clear that intelligence is not a static structure, but an open, dynamic system that can continue to develop throughout life. This understanding is being utilized not only in school systems but in the workplace, where training programs show that even at the adult level people are able to develop their intelligence more fully. Corporations such as Motorola have implemented programs in which they are training their employees, managers, and executives to think, problem-solve and create more effectively using strategies developed by such educational innovators as Reuven Feurstein, J.P. Guilford, and Edward de Bono. A most recent development is in the new kinds of technology that make it possible for people to take responsibility for their own learning as they access and process information through the internet, communicate with experts anywhere in the world, and use software that facilitate higher order thinking and problem-solving. Computers are in no way replacing teachers, but rather these new tools allow them to spend more time being facilitators, mentors, and guides. As a result, teachers and students are able more often to collaborate on creating new knowledge as well as mastering the basics. As technology becomes more ubiquitous, there is growing recognition of the importance of the arts in humanizing the curriculum. "More high-tech, more need for high-touch" is becoming the by-word of many schools. They recognize that the arts are not only culturally important and civilizing influences, but they can facilitate the learning of almost any subject. I believe that these four concepts--the plasticity of the brain, the modifiability of intelligence, the use of technology as a powerful new tool for learning, and the renaissance of the arts in education--have major implications specifically for educational systems and generally for the future of our world. In this time of rapid change, leading-edge educational systems are equipping people with the ability to learn, unlearn, and relearn continually. They are giving students meaningful opportunities to apply what they have learned in order to turn information into knowledge. And--of critical importance if any of this is to lead to a healthy future--they are helping students to learn to use knowledge responsibly, ethically, and with integrity. Furthermore, they are involving students in experiences that develop compassion and altruism in the process of their education. Our complex world urgently needs more people who have developed their fullest potential in mind, body, and spirit.

The Malaysian Telehealth Flagship Application: a national approach to health data protection and utilisation and consumer rights.

Telehealth refers to the integration of information, telecommunication, human-machine interface technologies and health technologies to deliver health care, to promote the heath status of the people and to create health. The Malaysian Telehealth Application will, on completion, provide every resident of the country an electronic Lifetime Health Record (LHR) and Lifetime Health Plan (LHP). He or she will also hold a smart card that will contain a subset of the data in the Lifetime Health Record. These will be the means by which Malaysians will receive "seamless continuous quality care" across a range of health facilities and health care providers, and by which Malaysia's health goal of a nation of "healthy individuals, families and communities" is achieved. The challenges to security and privacy in providing access to an electronic Lifetime Health Record at private and government health facilities and to the electronic Lifetime Health Plan at homes of consumers require not only technical mechanisms but also national policies and practices addressing threats while facilitating access to health data during health encounters in different care settings. Organisational policies establish the goals that technical mechanisms serve. They should outline appropriate uses and access to information, create mechanisms for preventing and detecting violations, and set sanctions for violations. Some interesting innovations have been used to address these issues against the background of the launching of the multimedia supercorridor (MSC) in Malaysia.

European Commission activities in eHealth.

Health-care is an information-intensive and knowledge-demanding sector, which is why eHealth solutions are so important in this field. The European Commission (EC) has been initiating and funding research and development activities regarding Information and Communication Technologies (ICT) for health, or "eHealth", since 1988. These programmes covered priority topics like electronic health-care records, regional and national health networks, telemedicine in homecare and care-at-the-point-of-need to support continuity of care concepts, systems to support people to stay healthy, and systems and tools to support health professionals to work more efficiently and safely on patients. During the 15-year span of the programmes, the European Union (EU) has contributed about 500 million Euro to approximately 400 R&D projects, support activities, best practice and studies covering technical, clinical, ethical, legal, organisational and market issues. eHealth has shown proven benefits in application fields like improved access to care, care at the point-of-need, citizen-centred care, improved quality and cost containment. Such applications were on show at the EU High Level eHealth Conferences in Brussels, Belgium, in 2003, and in Cork, Ireland, in 2004. eHealth is now on the governmental agenda of EU Member States to be implemented on a broader scale. In line with this development, the Commission has taken a number of policy initiatives. A European Union Action Plan for a European eHealth Area was published by the Commission in April 2004 and endorsed by the EU health ministers in June 2004. This means that, for the first time, Europe has a coherent agenda for the implementation of eHealth. This report will concentrate on eHealth activities initiated by the Information Society Directorate-General of the European Commission.

Developing the 'health-promoting school'--a national survey of healthy schools awards.

The concept of the 'Health Promoting School' has been widely advocated as an approach to enhancing public health through school based health promotion. In many areas 'Healthy Schools Award' schemes have been set up to support the development of this concept, but there is no information on how widespread this practice is in the UK, how standards are evaluated, and what effect Healthy Schools Awards may have on young peoples' health. This UK national survey aimed to determine the extent and nature of existing award schemes and how they were being evaluated. A postal questionnaire was sent to all 200 health promotion units in the UK; the response rate corrected for mergers of units was 78.5%. Sixty-eight respondents (51%) were involved with an award scheme and 28 (21%) were planning them. Current award schemes were mostly jointly run by the health and education sectors, encompassing 845 participating schools of which two-thirds were primary schools. The most common issues addressed were; standard chronic disease risk behaviour, the environment and health education in the national curriculum; less frequently addressed were mental health, accident prevention, staff health and developing links with the wider community. Evaluation was usually by target setting and assessment of progress over a two year period. However, evaluation was rarely external or independent, raising doubts about the standards obtained and validity of the approaches. This survey highlights the rapid growth of healthy schools award schemes and the need for wider exchange of information on good practice. In particular there is a need for more explicit and measurable standards of achievement to ensure the quality of award schemes, and further research into their effectiveness.

Spirometry and maximal respiratory pressure references from healthy Minnesota 65- to 85-year-old women and men.

OBJECTIVE: To obtain spirometry and maximal respiratory pressure (MRP) reference values for elderly persons. DESIGN: Survey. SETTING: General community. PARTICIPANTS: Four hundred seventy-one healthy ambulatory white women and men age 65+ years. METHODS: A stringent spirometry quality assurance program exceeded American Thoracic Society recommendations. A "healthy" subgroup of 176 women and 112 men between the ages of 65- and 85 years were identified by excluding those with conditions that negatively influenced FEV1 in a multiple regression analysis. Reference equations and normal ranges for FEV1, FVC, FEF25-75%, peak flow, and maximal inspiratory and expiratory pressures (MRPs) were determined from the healthy group with good quality maneuvers. RESULTS: Less than 10% of the subjects were unable to perform three acceptable spirometry maneuvers and ten MRP maneuvers. When the age and height corrected FEV1s from this group were compared with other spirometry reference studies, mean values from the women were nearly identical to those from Morris, while these men had substantially lower FEV1 values (by 0.3- to 0.5L) than elderly men in Crapo's study. Mean peak flow was over 20% higher when compared with previous studies, suggesting greater initial expiratory effort by our subjects. The maximal inspiratory pressure (MIP) values were about 20% higher than those reported by the Cardiovascular Health Study, perhaps because five MIP maneuvers were always performed. CONCLUSION: Spirometry and MRP reference values used for elderly patients should come from population studies using similar techniques and with large numbers of subjects over age 65 years.

Gender difference on the symptoms, health-seeking behaviour, social impact and sleep quality in irritable bowel syndrome: a Rome II-based survey in an apparent healthy adult Chinese population in Taiwan.

BACKGROUND: Little is known about the gender effect on irritable bowel syndrome in Asia. AIM: To assess the gender difference in Chinese subjects with irritable bowel syndrome meeting Rome II criteria. METHODS: Irritable bowel syndrome was identified from an apparently healthy adult population receiving a routine health maintenance program (n = 2018). RESULTS: Female gender is not a factor associated with irritable bowel syndrome or irritable bowel syndrome-related health care-seeking behaviour. Female irritable bowel syndrome subjects, irrespective of consulting behaviour for irritable bowel syndrome, are likely to have < 3 bowel movements/week, hard/lumpy stools and abdominal fullness/bloating (P < 0.05). Female irritable bowel syndrome subjects are prone to be absent from school/work with more days of absenteeism, irrespective of consultation status (P < 0.05). Only female irritable bowel syndrome consulters have more absenteeism for their irritable bowel syndrome-related symptoms, reporting more sleep disturbances than their male counterparts (P < 0.001). CONCLUSIONS: In an apparent healthy adult population in Taiwan, gender difference is present in Rome II defined Chinese subjects with irritable bowel syndrome as regards bowel symptoms, social impact and sleep quality. Female predominance was not found in irritable bowel syndrome subjects and irritable bowel syndrome-related health care-seeking behaviour in the current population. Both irritable bowel syndrome non-consulters and consulters have similar gender difference profiles in presenting symptoms, suggesting that bowel symptoms per se may not be the only factor leading to health care-seeking behaviour. The gender differences in sleep problems were observed solely in irritable bowel syndrome consulter.

[Human intestinal parasites in Subsaharan Africa. II. Sao Tomé and Principe].

In 1983 the authors carried out a survey in the Democratic Republic of São Tomé and Principe, analysing 1050 specimens of stools collected among the population from apparently healthy subjects chosen at random and in a number proportional to the distribution of the population in the regions of the country (about 1% of the population was examined). The examined subjects were divided into 3 age groups (0-3, 4-12, more than 12 years old), to have homogeneous groups in relation principally to modalities of life and nutritional patterns. There were 488 male subjects and 562 females. The survey was preceded by a sensitization of the people to the problem of intestinal parasites and by two preliminary surveys about the number of existing latrines and about people's believes and attitudes in relation to helmintiasis. The tests were made according to the modified Ritchie technique on fecal specimens preserved with 10% formol solution. The following results were found: a) Protozoa: Entamoeba coli, 43.0%; Iodamoeba buetschlii, 9.0%; Giardia intestinalis, 8.8%; Endolimax nana, 7.0%; E. histolytica, 5.5%; E. hartmanni, 2.5%; Chilomastix mesnili, 2.3%; Trichomonas intestinalis, 0.2%; Balantidium coli, 0.1%. b) Helminths: Trichuris trichiura, 87.7%; Ascaris lumbricoides, 64.3%; Ancylostomatidae, 40.5%; Strongyloides stercoralis, 6.8%; Hymenolepis diminuta, 0.3%; H. nana, 0.2%; Schistosoma haematobium, 0.2%. In 28.2% of the specimens (with more than 50% of subjects in some villages) eggs of Heterophyidae were found, very similar to Metagonimus yokogawai, but not yet identified by us, with the following characteristics: elliptical shape, average size 25 mu (22.2-27.7) X 18.5 mu (17-21), thick wall, operculum difficult to see, not sticking out from the outline but visible by focusing being in a different refractiveness, presence of a small polar knob, colour slightly brownish, asymmetric miracidium. Further investigations are necessary to identify the species of this trematode and to understand if it is a true human parasite or a pseudoparasite. The general results show the existence of a heavy fecal pollution all over the territory of the D.R. of São Tomé and Principe, connected with unhygienic life conditions, dangerous for health. This suggests to start urgently a sanitation program.

Spirometry reference values for American Indian adults: results from the Strong Heart Study.

STUDY OBJECTIVE: To derive spirometry normative values from a large population of American Indian adults and compare them to reference values for white adults. DESIGN: Pulmonary function was assessed using spirometry in participants of the Strong Heart Study, a multicenter, community-based, prospective study of cardiovascular risk factors and disease in American Indians, utilizing American Thoracic Society guidelines and a vigorous quality assurance program. SETTING: Central Arizona, southwestern Oklahoma, central South Dakota, and northeastern North Dakota. PARTICIPANTS: Acceptable spirometry results were obtained from 1,619 women and 1,005 men aged 45 to 74 years. RESULTS: Internal reference values and normal ranges for FEV(1), FVC, and the FEV(1)/FVC ratio were derived from a healthy subgroup of 253 women and 190 men, identified by excluding participants with factors associated with a lower FEV(1). Ten percent of the entire cohort (269 of 2,624 subjects) had airways obstruction, as defined by an FEV(1)/FVC below the lower limit of the normal (LLN) using the internal reference equations. After allowing for measurement "noise," 31 participants were below the LLN using reference equations for white adults from the large National Health and Nutrition Examination Study (NHANES) III study but were normal using the internal reference equations (1.3% false-positive), while 27 participants were classified as normal using NHANES III equations but had airways obstruction using the internal reference equations (1.2% false-negative). Similarly low misclassification rates were seen for a low FVC (prevalence, 17.6%). CONCLUSION: For clinical purposes, NHANES III spirometry reference equations for white adults may be used when testing American Indian women and men aged 45 to 74 years.
