A primary health care baseline survey in a rural district in Zambia.

In many developing countries health data are insufficient. These data are needed to get valid information to make decisions about health programmes. Baseline surveys are in terms of economy and resources a method which is fruitful. These baseline surveys should not only be performed at country and province level. Baseline surveys at district level is needed to monitor local needs. The present baseline survey was focus on immunization, diarrhoea incidence and diarrhoea treatment, sanitation and children nutrition status. 388 households were visited in a random 30 cluster baseline survey in Choma district of Zambia. It revealed that 79% of the children aged 12-23 months was fully immunized and the drop-out rate in polio and DPT vaccination routines was as low as 9 and 12% respectively. The incidence of diarrhoea disease was high and estimated at 4.8 episodes per child per year. ORS and SSS were used as treatment in 52% and 15% of all cases. More than 90% of mothers would seek help at RHCs or PHCs in case of diarrhoea. About 2/3 of the households had no safe water supply and 2/3 no pitlatrine. Only a few had a refuse pit. The nutrition status of children were assessed by using upper arm circumference measurements. Only about 40% of the children age 12-23 month and about 75% of children aged 24-59 months respectively were adequately nourished. The district had in this survey a fair immunization programme but intensified sanitary and nutritional programmes seem justified. Periodic baseline surveys with 2-3 years interval is recommended to determine the impact and future direction of the programme.

A community trial of the impact of improved sexually transmitted disease treatment on the HIV epidemic in rural Tanzania: 2. Baseline survey results.

OBJECTIVES: To determine baseline HIV prevalence in a trial of improved sexually transmitted disease (STD) treatment, and to investigate risk factors for HIV. To assess comparability of intervention and comparison communities with respect to HIV/STD prevalence and risk factors. To assess adequacy of sample size. SETTING: Twelve communities in Mwanza Region, Tanzania: one matched pair of roadside communities, four pairs of rural communities, and one pair of island communities. One community from each pair was randomly allocated to receive the STD intervention following the baseline survey. METHODS: Approximately 1000 adults aged 15-54 years were randomly sampled from each community. Subjects were interviewed, and HIV and syphilis serology performed. Men with a positive leucocyte esterase dipstick test on urine, or reporting a current STD, were tested for urethral infections. RESULTS: A total of 12,534 adults were enrolled. Baseline HIV prevalences were 7.7% (roadside), 3.8% (rural) and 1.8% (islands). Associations were observed with marital status, injections, education, travel, history of STD and syphilis serology. Prevalence was higher in circumcised men, but not significantly after adjusting for confounders. Intervention and comparison communities were similar in the prevalence of HIV (3.8 versus 4.4%), active syphilis (8.7 versus 8.2%), and most recorded risk factors. Within-pair variability in HIV prevalence was close to the value assumed for sample size calculations. CONCLUSIONS: The trial cohort was successfully established. Comparability of intervention and comparison communities at baseline was confirmed for most factors. Matching appears to have achieved a trial of adequate sample size. The apparent lack of a protective effect of male circumcision contrasts with other studies in Africa.

Validity and reproducibility of a self-administered food frequency questionnaire used in the baseline survey of the JPHC Study Cohort I.

We examined the validity and reproducibility of a 44-item food frequency questionnaire used in a baseline survey of the Japan Public Health Center-Based Prospective Study Cohort I conducted in February 1990. Subjects were 94 men and 107 women selected on a voluntary basis among respondents to the baseline survey. Four or five years after the baseline survey, they provided four 7-day diet records during a 1-year period, and then responded to the same questionnaire a second time. The median (range) for energy-adjusted correlation coefficients between 30 nutrients measured by the questionnaire and the diet records was 0.36 (0.06-0.81) for men and 0.37 (0.11-0.52) for women. The median correlation (range) for 17 food groups was 0.30 (0.08-0.75) for men and 0.28 (0.08-0.46) for women. The median correlation (range) for energy-adjusted correlation coefficients between the two questionnaires was 0.24 (0.04-0.69) for men and 0.50 (0.27-0.60) for women for the nutrients, and 0.34 (0.15-0.63) for men and 0.48 (0.18-0.55) for women for the food groups, respectively. The results indicate that this brief food frequency questionnaire provides reasonably valid and reproducible measures of consumption for many nutrients and food groups, and is useful for examining the association between diet and health in the Japanese population.

Assessment of blood pressure measurement quality in the baseline surveys of the WHO MONICA project.

Because of the general inavailability of reference standards, there exist no common procedures to assess the quality of blood pressure measurements in epidemiological population surveys. To approach this problem within the collaborative international WHO MONICA Project, a standardized assessment of BP measurement quality was developed and applied to the forty-seven baseline surveys of that project. The entire assessments were carried out in retrospect, that is, only after each population survey had been completed. The assessment was focused on the procedures of quality assurance and control as reportedly applied in each survey, and on quality indicators which were derived from the recorded blood pressure values of each survey. The definitions of specific quality assessment items were based on the MONICA project protocol and on sources in the pertinent literature. The available information on quality assurance and control procedures depended solely on self-reports by local survey organizers and on site visits, and was occasionally found to be at variance with the actual blood pressure recordings. Therefore, quality indicators derived from actual blood pressure recordings were far more informative and comparable between surveys. Each survey was rated as optimal, satisfactory, or unsatisfactory with regard to single quality items and these single scores were used jointly to compute a summary score of blood pressure measurement quality for each survey. This summary score indicated that 39 out of 47 MONICA baseline surveys showed optimal or satisfactory BP measurement quality. Limitations and potentials for improvement of quality assessments became apparent. We conclude that a standardized assessment of BP measurement quality in epidemiological population surveys seems feasible and propose that quality assessment methods similar to the ones suggested here become a routine part of future epidemiological analyses of blood pressure values and hypertension in populations. This should facilitate valid study comparisons.

Smallholder farming of the greater cane rat, Thryonomys swinderianus, Temminck, in southern Ghana: a baseline survey of management practices.

Baseline management practices and productivity of captive greater cane rats were studied between February and July 1992 using questionnaires with 33 practising and former farmers in 16 villages in three regions in southern Ghana. The colony sizes were relatively small, ranging between 1 and 96, with nearly a 100% farmer drop-out rate. The mean litter size of the greater cane rats in this study was 4.8+/-0.13, with the young being weaned at 8.8 weeks old. Although nearly all the farmers interviewed (90.9%) had long-term commercial intentions, a number of problems militating against their objectives were encountered. These included lack of technical support on proper management practices for efficient production, housing design, dry season feeding, sex determination and the acquisition of foundation stock. In conclusion, these studies have shown the generally poor state of the greater cane rat industry in Ghana, which requires research into almost all aspects of the productivity of this animal under captive breeding.

Fruit and vegetable intake in the United States: the baseline survey of the Five A Day for Better Health Program.

PURPOSE: The purpose of the Five A Day Baseline Survey was to assess fruit and vegetable intake and associated factors among US adults. DESIGN: Questionnaires querying frequency of intake of 33 fruits and vegetables, as well as demographics, attitudes, and knowledge related to fruits and vegetables were administered by telephone. SETTING: The study was a nationally representative random digit dial survey conducted by telephone in the summer of 1991; response rate was 42.8%. SUBJECTS: Respondents were 2811 US adults (including an oversample of African-Americans and Hispanics). MEASURES: Mean and median self-reported intakes of fruits and vegetables were calculated. Estimated servings per week were adjusted on the basis of responses to summary questions regarding overall fruit and vegetable intakes. RESULTS: Median intake of fruits and vegetables was 3.4 servings per day. Linear regressions (accounting for no more than 10% of the variation) showed that education, income, and smoking status were predictors of fruit and vegetable intake and that intake increased with education, income, and nonsmoking status. Women had higher intakes than men at all ages; these differences between men and women increased with age. Fruit and vegetable intakes increased with age for whites and Hispanics, but not for African-Americans. CONCLUSIONS: Fruit and vegetable intake among adults in the United States is lower than the recommended minimum of five daily servings. These data will be useful in targeting campaign efforts and in assessing progress of the Five A Day for Better Health Program.

Smoking and drinking habits among the JPHC study participants at baseline survey. Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Diseases.

Smoking and drinking habits at baseline survey among 110,896 male and female residents aged 40-69 are reported as part of an ongoing prospective population-based cohort in 11 geographically diverse health centers in Japan. The age-adjusted proportion of current and former smokers was 54.8% and 21.8% in males and 8.3% and 2.1% in females, respectively. Mean age at initiation of smoking in males and females was 20.6 and 27.8 years of age, respectively. In males, the age-adjusted proportion of those who drink almost daily was 49.1% and that of those who drink almost never was 19.7%, while in females, it was 5.9% and 71.6%, respectively. When compared by health center, the proportion of male current smokers was lower in Miyako and Ishikawa, both located in Okinawa Prefecture, while in females the proportion was higher in urban areas, such as Katsushika and Suita. The proportion of those who drink almost daily in males was higher in Yokote, Kashiwazaki, Katsushika and Suita, and lower in Ishikawa and Miyako, but in Ishikawa and Miyako, the proportion of those who drink at social events was higher. In females, the proportion of those who drink almost daily was higher in urban areas. There was substantial variation in the types of alcohol beverages consumed by males. In contrast, alcohol consumption in females comprised mainly beer.

Baseline survey of JPHC study--design and participation rate. Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Diseases.

The data collection from cohort subjects at baseline is the core work for prospective study as well as follow-up. We set up 140,420 cohort subjects (68,722 men and 71,698 women) (61,595 in 1990 as Cohort I and 78,825 in 1993 as Cohort II) based on resident registry of 29 districts under 11 Public Health Center areas and baseline survey were submitted for them. The survey consisted of the following three components: (1) self-administered questionnaire survey, (2) collection of blood samples (plasma and buffy coat) for deep-freezed storage and (3) collection of health check-up data. All survey were completed during the first five year of each study. Among all cohort subjects, 113,461 (81%) (53,375 men and 60,086 women, 50,245 in Cohort I and 63,216 in Cohort II) returned the questionnaire and 49,011 (35%) (18,159 men and 30,852 women, 24,637 in Cohort I and 24,374 in Cohort II) provide their blood. The health check-up data were collected from 47,910 (34%) (17,276 men and 30,664 women, 23,311 in Cohort I and 24,599 in Cohort II). These data and blood samples serve as basis for the Japan Public Health Center-based prospective Study on cancer and cardiovascular diseases (JPHC Study).

Social class and risk factors for coronary heart disease in the Federal Republic of Germany. Results of the baseline survey of the German Cardiovascular Prevention Study (GCP).

The relationship between social class and seven important risk factors for coronary heart disease has been evaluated utilising data from the German Cardiovascular Prevention Study baseline survey. Of German residents aged 25 to 69 years, 16,430 were randomly selected from both the six intervention regions and the Federal Republic of Germany to undergo the screening procedures between 1984 and 1986. Among males the prevalence of cigarette smoking and lack of physical activity was associated with social class. For females, overweight and physical activity demonstrated a strong social gradient. No relationship existed between social class and hypercholesterolaemia. The prevalence of Type A behaviour was significantly higher for the upper social classes. The number of CHD risk factors per study subject increased with decreasing social class. Predicted cardiovascular mortality was clearly higher for the lower social class among males in general and for females younger than 60 years. These findings point to the need for risk factor intervention strategies focusing more on the lower social classes in order to achieve more adequate prevention of coronary heart disease.

Serum total and high-density lipoprotein cholesterol--reference values obtained in the Coronary Risk Factor Study baseline survey.

Serum total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, and HDL/TC ratios have been established in 7 188 males and females aged 15-64 years who participated in the 1979 Coronary Risk Factor Study (CORIS) baseline survey in the southwestern Cape. TC levels in a sample of 575 1- and 2-year-olds were also determined. TC levels were found to be considerably higher at all ages than corresponding values found in recent surveys in the USA. By fitting epidemiological values associated with a low risk of coronary heart disease (CHD) to the CORIS data, cut-off points (CPs) for 'desirable' TC and HDL levels and HDL/TC ratios were obtained. The CPs for TC are considerably lower than those commonly used by pathology laboratories, and their adoption would result in a greater proportion of the 'westernized' population being regarded as being at risk of CHD, and therefore as requiring diet modification or drug treatment. Experience with the diagnosis of familial hypercholesterolaemia (FH) suggests that the CORIS 80th percentile for TC will correctly identify over 90% of cases of FH. On the basis of this, TC CPs for population screening for FH are also presented.

A baseline survey on use of drugs at the primary health care level in Bangladesh.

The drug use pattern and the quality of care were assessed in 80 public sector facilities throughout rural Bangladesh. A total of 40 thana health complexes and 40 union subcentres, the lowest level in primary health care facilities, were selected at random. A total of 2880 prescriptions, consultations, and drug-dispensing practices were studied, and the availability and use of essential drugs and of the essential drugs list were recorded. The average consulting time (54 seconds), the proportion of adequate examinations (37%), and prescription of drugs according to standard treatment guidelines (41%) were unsatisfactory. The mean number of drugs prescribed per patient was 1.44; 25% were treated with antibiotics, and 17% with metronidazole, irrespective of the diagnoses. The availability of drugs (54%) and the presence of an essential drugs list (16%) in the health facilities were low. However, 78% of the drugs were prescribed by their generic names, 85% complied with the essential drugs list, and 81% were dispensed according to prescription. The average dispensing time (23 seconds) and the proportion of patients who correctly understood the dosage (55%) were poor.

Fruit and vegetable consumption of rural African Americans: baseline survey results of the Black Churches United for Better Health 5 A Day Project.

The objective of this study was to determine baseline fruit and vegetable consumption (total and specific) among rural African Americans participating in a 5 A Day intervention study and factors associated with this dietary intake. A telephone survey was administered to 3,737 adult members of 50 black churches from 10 rural counties in North Carolina. The survey measured demographic characteristics, knowledge and beliefs regarding cancer and nutrition, and food-frequency data related specifically to fruit and vegetable consumption. Associations between fruit and vegetable consumption and income, education, age, gender, marital status, the presence of children within the household, and awareness of the 5 A Day program were explored using descriptive and regression analyses. Food-frequency data showed a mean intake of 3.7 +/- 2.4 daily servings of fruits and vegetables within this population of rural African Americans. Twenty-three percent of the participants reported eating five or more daily servings of fruits and vegetables. Significant associations were found between fruit and vegetable intake and both age and gender (p < 0.001), with older females consuming the most and younger males consuming the least fruits and vegetables. Findings from this rural African American population parallel national studies showing that US intake of fruits and vegetables falls short of the 5 A Day guidelines. Female gender and advancing age were positively associated with fruit and vegetable intake. Study results reinforce the need to promote the 5 A Day message. Such messages may prove most beneficial if targeted toward younger adult males, whose fruit and vegetable intakes are especially low.

Analyses of baseline survey data on rinderpest in Bahr el Ghazal Province, with proposal of an improved vaccination strategy against rinderpest for southern Sudan.

Results from analyses of baseline surveillance data on rinderpest are used for proposing an improved vaccination strategy against rinderpest in southern Sudan. Sera from 4,074 (47%) of the total sample of 8,565 cattle collected in a series of cross-sectional surveys in 400 cattle camps in the Bahr el Ghazal Province of southern Sudan were tested for rinderpest antibodies using the standard virus neutralisation test (VNT) technique: 77.4% were positive while 22.6% gave negative results. The data were cross-classified according to five variables: herd management, breed, age, sex and geographic region (grazing location). The percentage antibody-positivity level (taken as an approximation of past experience with rinderpest antigen and the corresponding prevalence ratio estimates of relative risk) for each variable are discussed within the context of the known characteristics of immunity to rinderpest in endemic areas and the husbandry practices of the cattle owners in the study area. Results suggest that rinderpest "hot-spots" of transmission and/or low level of herd immunity should be mapped out for concentrated efforts to vaccinate calves and young adults so that the high level of antibody-positivity observed in this study can be maintained and transmission permanently interrupted.

Health status, life habits, and social background among the JPHC study participants at baseline survey. Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Diseases.

A self-reported questionnaire on the health status, life habits, and social background was conducted at baseline in the Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Diseases (JPHC study). This report presents the outcome of the study regarding past or family history of various diseases, medical treatment, life habits such as physical labor or sports, and social background among study participants. In both cohorts I and II, prevalent past and family history included hypertension, stroke, and cancer, whereas the prevalence of coronary heart diseases was historically low. The prevalence of a past history of hypertension and stroke was higher in the northern part of Japan, Ninohe, and Yokote, and lower in Okinawa, compared to the other districts. The prevalence of participants with a history of stomach cancer and liver cancer was higher in Arikawa than in other districts. The frequency of participants who took medication from doctors ranged from 20% to 30%, higher in the Tohoku areas, and lower in Okinawa compared to the other districts. All districts showed a high rate of over 70% for the participation rate for basic health examination conducted by the local government, The rate was particularly high in the Tohoku area where a high prevalence of a history of hypertension was found. The frequency of persons who had a chance to participate in sports or physical exercise was high in Okinawa and Suita subcohort 2, although the mean total physical activity (both at work and for leisure time) was lowest in the latter subcohort. No substantial differences were found in compositions of personality among districts. The frequency of more active and positive persons, however, was relatively higher in urban areas and lower in Okinawa compared to the other districts. The association between the differences of health status, life habits, and social background and the occurrence of various lifestyle-related diseases will be clarified in a follow-up study within the JPHC study.

Seroepidemiology of hepatitis B virus infection in Saudi Arabian children: a baseline survey for mass vaccination against hepatitis B.

Saudi Arabia is considered to be an area of endemic hepatitis B virus (HBV) infection. By adult age, 7% persons have hepatitis B surface antigen (HBsAg) and about 70% have one or more HBV markers. In order to provide a baseline for the integration of hepatitis B vaccine into the extended programme of immunisation (EPI), a population-based survey of HBV markers was made among Saudi children. The overall prevalence of HBsAg was 6.7%, with at least one HBV marker being positive in 19.7% persons tested. Two peaks of HBV prevalence were observed in the 7- and 10-year-old children respectively. The prevalence of HBsAg was steady in all age groups with identifiable but insignificant peaks in children aged 4 and 7 years respectively. Despite the apparent homogeneity of the Saudi population, the prevalence rates of HBV varied among the regions and were higher in urban dwellers. There was no significant difference in the HBsAg prevalence for the sexes (7.3% for males and 6.0% for females). Socioeconomic factors and family size did not significantly influence the prevalence of HBV among children. Of 307 HBsAg-positive children, 55 (17.9%) were positive for HBeAg. The early acquisition of HBV in the Saudi population is confirmed. The most effective strategy for HBV control, therefore, is by mass vaccination of all Saudi infants. An extension of the immunisation programme so as to include all pre-school children should further reduce the reservoir of HBV in Saudi Arabia. A repetition of a similar survey after 5 and 10 years should be made in order to measure this reduction.

Dietary habits among the JPHC study participants at baseline survey. Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Diseases.

Dietary habit is closely associated with development of cancer and cardiovascular diseases, however little prospective evidence has been published for Japanese, whose dietary habit is substantially different from Western countries. Therefore, frequencies of food consumption, food preference, cooking method and acceptance of dietary advice were investigated at the baseline by two kinds of self-administered food frequency questionnaires. Dietary habits between urban and rural (Tokyo and Osaka vs. others), or between Okinawa and non-Okinawa revealed recognizable differences. The so-called westernized foods such as bread, beef and coffee were more consumed in the urban areas such as Tokyo and Osaka and also in Okinawa. The frequencies of salted food intake such as pickled vegetables and salted seafoods were remarkably low in Okinawa. Cooking methods for meats, seafoods and vegetables were also unique in Okinawa. No distinct geographical difference was shown in food preference and modification of dietary habit by dietary advice.

Breast and cervical cancer screening among underserved women. Baseline survey results from six states. The National Cancer Institute Cancer Screening Consortium for Underserved Women.

OBJECTIVE: To characterize breast and cervical cancer screening rates in selected underserved populations and to compare the rates with objectives for the year 2000. DESIGN: Six random-sample surveys were conducted in underserved populations between 1991 and 1993. Two of the surveys were random-digit-dial telephone surveys; four were conducted using in-person interviews. SETTINGS: The studies were conducted in the following target populations: (1) low-income and minority women residing in urban areas in Minnesota, Rhode Island, and North Carolina; (2) Hispanic women residing in urban communities in Texas; and (3) women residing in rural West Virginia and Wisconsin. PARTICIPANTS: A total of 6648 noninstitutionalized women aged 40 years or older were interviewed. MAIN OUTCOME MEASURES: Self-reported knowledge and practices related to mammograms and Papanicolaou smears. RESULTS: Between 35% and 79% of women had ever had a mammogram, and between 27% and 66% reported having a mammogram in the past 2 years. Between 82% and 95% of women had ever had a Papanicolaou smear, and between 55% and 74% reported having a Papanicolaou smear in the past 3 years. Women with low levels of education, below 200% of the poverty level, with no health insurance, 80 years or older, residing in Appalachian West Virginia, and Hispanic women residing in urban Texas have the farthest to go to reach the cancer screening objectives for the year 2000. CONCLUSIONS: Although access to health care is high among the women studied, screening rates are uneven. Objectives for the year 2000 clearly are attainable for some populations of underserved women, though much work needs to be done if objectives are to be met for all subgroups.
