Maternal factors associated with delivery of infants with birthweight less than 2000 grams in a low socioeconomic population.

Women of low socioeconomic status (SES) are known to have a higher incidence of low birthweight (LBW) infants who are a major source of neonatal mortality and morbidity. SES, however, does not define a homogeneous population. If prenatal programs could be oriented specifically toward women of higher risk within the low SES population, they should be more effective. Within our uniformly low SES population, we compared mothers who had given birth to infants weighing less than 2000 g with mothers of infants weighing over 3000 g in order to identify factors associated with a LBW birth. We found medical factors, including hypertension and infection during pregnancy, demographic factors, including race, marital status, and lack of prenatal care, and lifestyle factors, including drug and alcohol abuse, to be more common among women giving birth to infants weighing less than 2000 g. These factors can be used to develop more effective intervention programs for low SES populations.

Racial differences in psychosocial variables among adults with non-insulin-dependent diabetes mellitus.

To determine whether racial differences exist in psychosocial variables among patients with non-insulin-dependent diabetes mellitus (NIDDM), the authors administered a series of questionnaires to 211 Black and White patients of the Wake Forest Family Medicine ambulatory care unit and the Reynolds Health Center, a community health center. In general, Blacks in the study population had higher levels of external locus of control, higher levels of stress, and lower levels of family functioning compared with Whites. These differences may account partially for the disparity of diabetes control and the consequences of diabetes among Blacks. Health professionals may benefit from understanding and addressing these psychosocial variables and may be more successful in implementing intervention programs in this population by tailoring programs to the psychosocial orientation of their population.

Computer program designed to follow fluctuations in microbial populations and its application in a study of Chesapeake Bay microflora.

A computer program has been developed which performs cluster analysis of microorganisms using methods of numerical taxonomy. The program is designed to group related strains, identify the groups by reference to known strains, and calculate a hypothetical median organism (HMO) for each group. The HMO serves to condense taxonomic information and provides a tag for each strain cluster. Every strain in a group is compared with the HMO established for that group. A representative strain for the group is obtained by selection of the strain showing highest similarity to the HMO. New data sets can be compared with data sets of previous analyses. Hence, the occurrence of the same taxonomic groups within separate data sets can be determined. Quantitative or qualitative differences in distribution of taxonomic groups within or between data sets can be measured. The output from the computer is a graphical display, using an on-line plotter; thus, the investigator is provided with visual comparison of data sets. Results obtained from a study applying the computer program in an analysis of taxonomic data obtained for 43 bacterial strains isolated from Chesapeake Bay indicate the usefulness of this method of taxonomic analysis in microbial ecology.

Growth-associated traits in parental and F1 populations of chickens under different feeding programs. 1. Ad libitum feeding.

Two experiments were conducted to compare body composition, plasma concentrations of glucose, lipid and protein, gastrointestinal tract (GIT) morphology, and digestive enzyme activities among populations of chickens exhibiting wide differences in growth. In the first experiment, males from a high weight (HW) line, a low weight (LW) line, and crosses between the lines (HL) were examined. In the second experiment, the same high weight (HW') line, a White Leghorn (LEG) line and their crosses (HLEG) were compared. In both experiments, comparisons were made at both 25 and 61 days of age. The HW chicks were heavier and had larger breasts and longer shanks than the LW or LEG chicks. Although the crosses (HL, HLEG) exhibited values for these traits intermediate to those of the parental lines, HLEG chicks tended to resemble one of the parental lines more closely than did the HL chicks. Differences among all mating combinations were significant for body fat, but the crosses (HLEG, HL) tended to more closely resemble their HW parental line. The HW chicks had significantly higher concentrations of glucose, lipid, and protein in plasma at 25 but not 61 days of age. No differences in glucose, lipid, or protein concentrations in plasma were observed in the second experiment. When expressed as a percentage of body weight, LW and LEG chicks tended to have larger GIT than HW chicks, whereas crosses more closely resembled the HW line. Although significant differences in digestive enzyme activities were obtained, these differences were generally associated with differences in body weight. It was concluded that genetic variation in the traits examined was dependent on both population and age.

Enhancing the role of case managers with specialty populations: development and evaluation of a palliative care education program.

Palliative home care is an important component of the care system for patients at the end of life and case management is considered an essential element of the Canadian home care system. Case managers play a critical role in allocating resources, thus influencing the costs and the viability of palliative home care. Case management education programs focused on care coordination with specialty palliative care populations are nonexistent. An education program targeted at improving the knowledge and skills of case managers in allocating resources to palliative care populations was developed and pilot-tested in a metropolitan Canadian city home care program. Core curriculum was based on an initial learning needs assessment and used case-based problem solving to enhance case-management skills. An improvement in knowledge was noted on posttests and case managers described increased comfort and confidence in their role as case managers to this patient population. Home care organizations caring for palliative care populations must ensure case managers are prepared for case management roles with specialty populations if the home is to be rendered an appropriate and viable care setting for patients at the end of life.

Asia's family planning programs as low fertility is attained.

The dramatic demographic changes in Asia during the three decades from 1970 to the end of the twentieth century were matched by major changes in government population policies and programs. Fertility declines occurred in widely different economic, sociocultural, and political settings. The extent to which they were attributable to family planning programs, established in most countries of the region by 1970, is hotly debated. The 1970s were the heyday of family planning programs, which were created in a climate of urgency because of concerns over the "population explosion." Issues faced by programs at that time are discussed. Over time, programs generally have moved to a simpler "service" approach. As increasing numbers of countries reach replacement-level fertility, and as policies are formed against the background of the 1994 International Conference on Population and Development held in Cairo, the role of family planning programs is increasingly debated and questioned. This article examines the responses of Asian countries and the population challenges that remain.

Perception of preventive health needs in a prostate-cancer screening population: a preliminary report.

In follow-up of a screening program for prostate cancer, 192 men from the urban Denver area and 244 men from rural northeastern Colorado completed a mailed questionnaire addressing their health and medical care, insurance coverage, lifestyles, and desire for health education and screening programs. Rural respondents were older and more were self-insured. Twice as many urban men were prompted to participate in the prostate screening program by media announcements (51.0% vs 23.4%), while spouses (21.3% vs 9.4%) and physicians (13.1% vs 6.8%) played greater roles in motivating rural participants. The primary topics for health information and education needs perceived by the rural men were cancer-related, while those for urban men concentrated on cardiac risk factors. Both preferred that this information be provided in the form of written materials or through their personal physicians. This pilot study suggests certain differences in the present health practices, motivational factors, and health information and education needs in urban versus rural men. These differences should be explored further and be considered in the design of cancer prevention and screening programs for these populations.

Serial SimCoal: a population genetics model for data from multiple populations and points in time.

UNLABELLED: We present Serial SimCoal, a program that models population genetic data from multiple time points, as with ancient DNA data. An extension of SIMCOAL, it also allows simultaneous modeling of complex demographic histories, and migration between multiple populations. Further, we incorporate a statistical package to calculate relevant summary statistics, which, for the first time allows users to investigate the statistical power provided by, conduct hypothesis-testing with, and explore sample size limitations of ancient DNA data.

[An evaluation on effectiveness of worksite-based intervention for cardiovascular disease during 1974 - 1998 in capital iron and steel company of Beijing].

OBJECTIVE: To explore the feasibility and effectiveness of worksite-based cardiovascular disease (CVD) prevention and control program in urban population of China. METHODS: Worksite-based intervention program was implemented 110 000 employees at Capital Iron and Steel Company of Beijing (CISC) focusing on primary prevention for CVD and control of hypertension. Intervention components comprised of infrastructure setting-up, health education and health promotion, professional training, detection and management of hypertensive patients, and reasonably readjusting their diet structure focusing on salt intake reduction, reducing their overweight, quitting smoking, and restricting alcohol consumption in high-risk population. Changes in level of risk factors, incidence and mortality of stroke and coronary events and their trend were evaluated between the intervention group at CISC and eight simultaneously parallel reference groups in other provinces outside Beijing with population surveillance data. RESULTS: Major risk factors for CVD, including blood pressure, body mass index and serum cholesterol level, decreased relatively in intervention population at CISC during 1974 to 1998, while those in majority of eight parallel reference groups at different provinces of China significantly increased at the same time. Systolic blood pressure (SBP) decreased by 0.8 mm Hg and 4 mm Hg in average for men and women, respectively, and their diastolic blood pressure (DBP) remained the same as baseline for both men and women at CISC, while SBP increased by (2 - 11) mm Hg and (6 - 8) mm Hg in average for men and women, respectively in reference groups, and DBP increased by (2 - 6) mm Hg in average for men in five of eight reference groups, and by (3 - 6) mm Hg for women in four of eight reference groups. Serum level of cholesterol decreased by 0.26 mmol/L in women and slightly increased for men at CISC, and increased by (0.35 - 0.97) mmol/L for men and (0.29 - 1.05) mmol/L for women in all reference groups. Prevalence of overweight increased by 58.7% for men and 11.3% for women at CISC and increased by one to 22 folds in eight reference groups. Awareness of health knowledge improved significantly with an average net reduction of SBP/DBP of (2.5/2.2) mm Hg in the enforced intervention group at CISC than that in general intervention groups. Incidence and mortality rates of stroke decreased by 54.7% and 74.3%, respectively in intervention group at CSIC, but those of coronary events slowly increased with fluctuation. CONCLUSION: Worksite-based comprehensive intervention for CVD prevention and control was feasible and cost-effective in decreasing risk factors for CVD, incidence and mortality rate of stroke in population of urban areas of China.

A hospital-based infant safety seat program for low-income families: assessment of population needs and provider practices.

Evaluation of a hospital-based car safety seat education and loan program for low-income families included hospital interviews with new mothers (N = 94), a survey of pediatricians (N = 28), and a task analysis of the program coordinator's time. Mothers who entered the hospital with safety seats were more likely than those without safety seats to (1) be White or Mexican-American than Black; (2) not be dependent on public transportation; (3) have an older child who always rides in a car seat; and (4) wear seat belts themselves. Mothers with seats did not differ from mothers without seats in knowledge or beliefs about the importance of, or intent to use, car seats. Of mothers without seats, 86.3% were aware of the hospital's car seat rental program, but only 12 of 51 rented a seat from the program. 61% of pediatricians surveyed believed that mothers' lack knowledge and skills to acquire and use car seats regularly, but only 31% always included education about the importance of using car seats and only 21% always referred mothers without seats to the rental program. Car seat loan programs addressing low-income populations should place greater emphasis on education of medical providers to provide education and referrals, encourage organizational policy that requires a safe first ride home and address issues of social support and perceived norms and ease of acquisition.

[Fertility decline in China and family planning programs].

"The article looks in detail at the population development in China since the 1950s, highlighting some dramatic changes. In the late 1950s the country was hit by widespread famine, which resulted in increased mortality and decreased fertility. Infant mortality climbed to almost 300/1,000. During the 1960s fertility began to increase again and mortality declined. From the beginning of the 1970s fertility started to decline, dropping from about six to just over two children per woman in the late 1980s. Today, fertility is thought to be below replacement level. The main reason for this fertility decline lies in the highly efficient family planning programmes implemented in China since the 1950s and particularly since the 1970s. The decline in infant mortality and the favourable socio-economic development have also been important factors in the decline in fertility. Although fertility in China is currently at a low level, the country's population is still set to grow." (SUMMARY IN ENG)

Estimation of population pharmacokinetics for carbamazepine in Malaysian patients using the OPT computer program.

We used OPT to estimate individual and population pharmacokinetics for carbamazepine (CBZ) in Malaysian epileptic patients attending our Neurology Clinic. We noted that plasma CBZ concentrations and clearances correlated poorly with daily doses and body weights respectively but we found the values for clearance, volumes of distribution, elimination rate constants and half lives to be in good agreement with earlier reports. We conclude that OPT is a simple yet useful program to derive individual and population pharmacokinetic parameters for CBZ for use in dosage adjustments. We also conclude that although the Malaysian population do not differ substantially in handling CBZ, available data for the pharmacokinetic parameters must be used cautiously in applying it to the therapeutic drug monitoring for CBZ in our patients.

Primary prevention of chronic disease among children: the school-based "Know Your Body" intervention trials.

The "Know Your Body" project, initiated in 1975 with funding from the National Heart, Lung, and Blood and the National Cancer Institutes, was developed in response to the empirically-validated suggestion that the primary prevention of chronic disease should begin in childhood. The aim of the program is to favorably modify the population distributions of risk factors for these diseases through changes in their behavioral antecedents. The program is classroom-based and teacher-delivered, and consists of three primary intervention foci: diet, physical activity, and cigarette smoking prevention. The program was subjected to a field trial among two demographically dissimilar populations of schoolchildren in the New York City area. After five years of intervention in one of the populations, the program was associated with significant favorable changes in blood total cholesterol levels and dietary intake of total fat and carbohydrate. In both populations, the program was associated with significant favorable changes in knowledge. After six years of intervention, the program was associated with a significant net reduction in the rate of initiation of cigarette smoking. If these findings can be replicated among diverse populations of schoolchildren, they suggest that such programs may be effective in reducing the population risk for the future development of chronic disease.

Strategies for the prevention of environmental neurotoxic illness.

Toxic chemicals in the environment can cause a wide range of neurological disease. High-dose exposures to environmental neurotoxicants have produced encephalopathy in children ingesting chips of lead-based paint, blindness in persons who ingested methanol, blindness and ataxia in persons who consumed organic mercury, spinal cord degeneration and peripheral neuropathy in persons exposed to tri-ortho-cresyl phosphate (TOCP), and Parkinsonism in persons exposed to MPTP or to manganese. Environmental neurotoxicants have also been shown to produce a wide range of subclinical neurotoxic effects, including reduction in intelligence, impairment in reasoning ability, shortening of attention span, and alternation of behavior. The first step in the prevention of environmental neurotoxicity is to test chemicals for their toxic potential. More than 70,000 chemicals are currently in commerce. However, except for pharmaceuticals, fewer than 10% of these chemicals have been tested for neurotoxicity. A logical approach to neurotoxicologic assessment of chemical substances will build on and extend currently available test systems. It will have a tiered structure. The first or screening tier will consist of tests to measure obvious structural and functional changes, often a functional observational battery. Subsequent levels of testing will be guided by the results of initial screening. Toxicologic testing must be supplemented by epidemiologic surveillance of populations exposed to known and suspect neurotoxicants. Screening programs in these populations designed to detect excessive absorption of a neurotoxic agent or subclinical neurological dysfunction can be useful in identifying affected individuals before severe disability occurs.

Medical and nursing education and training opportunities to improve survivorship care.

Improving the quality of care for cancer survivors is contingent on having physicians, nurses, and other professionals with adequate training in survivorship care. Previous literature has documented the deficiencies in existing formal education programs regarding the complex needs of this growing population. Continuing education programs and basic curricula need to incorporate the expanding body of knowledge regarding the physiologic and psychosocial sequelae of survivorship. This article reviews the current status of survivorship education and provides direction for essential content in future education. Topics such as prevention of secondary cancers, long-term complications, rehabilitation services, quality-of-life issues, pain and symptom management, and treatment of recurrent cancer are critical competencies of education that should then become routine care for cancer survivors.

Time-space clustering of human brucellosis, California, 1973-1992.

Infection with Brucella spp. continues to pose a human health risk in California despite great strides in eradicating the disease from domestic animals. Clustering of human cases in time and space has important public health implications for understanding risk factors and sources of infection. Temporal-spatial clustering of human brucellosis in California for the 20-year period 1973-1992 was evaluated by the Ederer-Myers-Mantel, Moran's I, and population-adjusted Moran's I procedures. Cases were clustered in concentrated agricultural regions in the first 5-year interval (1973-1977). Time-space clustering of human brucellosis cases in California late in the 20-year study period may reflect the distribution of Hispanic populations. Public health programs in California should focus on educating Hispanic populations about the risk of consuming dairy products, such as soft cheeses, made from unpasteurized milk.
