Criteria for selection of communities in poor rural areas with high risk of low weight babies.

In planning public health activities to reduce the incidence of low birth weight babies (LBW) in poor rural areas, it is necessary to identify the communities which require priority actions. The study population consisted of ten rural communities with similar characteristics. All were composed of coffee plantation workers with the same source of income, similar dwellings and dress, and all were located in the same climatic zone. However, the communities showed a variability of 72% in the incidence of LBW babies. Birth weight in the communities was significantly associated with maternal weight in the first trimester of pregnancy, daily caloric intake in the first and third trimesters of pregnancy, prevalence of houses with the kitchen in the sleeping area, literacy rate and ease of access to villages. Thus the identification of communities which would require priority in public health activities can be accomplished using simple indicators. Health activities should be combined with nutrition and education programmes and improvement both of sanitary conditions and of the means of access to population centres.

The impact of ordinary illnesses on the dietary intakes of malnourished children.

The effect of respiratory infections, diarrhea, illness-induced apathy, and of a summary variable of selected common symptoms on food intake was estimated from data collected on preschool children from rural Guatemala. The presence of selected common symptoms was associated with an average reduction in daily intake of nearly 20%, equivalent to 175 kcal and 4.8 g of protein. Effects were of similar magnitude for diarrhea and for apathy but lower for respiratory infections, namely 61 kcal and 1.0 g of protein. It is concluded that common illnesses are an important cause of low dietary intakes in children from Guatemama.

Nutrition and cognitive development among rural Guatemalan children.

Women and children from four Guatemalan villages participated in a voluntary food supplementation program for seven years. In two of the villages, they received a vitamin and mineral fortified, high-protein calorie supplement. In the other two villages, the vitamin-mineral fortified supplement contained no protein and a relatively small number of calories. Cognitive tests were administered regularly to children ages three to seven, and anthropometric measures obtained. In addition, measures of families' social milieu were collected at several points in time. Using multiple regression analysis, we find that both nutritional and social environmental measures are related to various dimensions of cognitive competence. The results suggest that nutritional intake, independent of social factors, affects cognitive development. There is also some evidence that the children who receive the high-protein calorie supplement (and whose mothers received it during pregnancy and lactation) are more likely to score high in cognitive performance. Our results, while not diminishing social environmental explanations of differences in cognitive function, suggest benefits from nutrition intervention programs in rural areas of lesser-developed countries.

Effect of maternal nutritional status and infant supplementation during lactation on postpartum amenorrhea.

This paper explores the effects of maternal nutritional status and food supplementation ingested by the infant on the duration of postpartum amenorrhea. A significant negative association was found between the nutritional status of the mother during the third trimester of pregnancy and the length of postpartum amenorrhea. A negative association was also found between infant supplementation and duration of postpartum amenorrhea. Each of these associations remained significant after controlling for the other, suggesting that both factors independently affect the length of postpartum amenorrhea.

Population characteristics and the distribution of general medical practitioners.

By applying the logic of the Resource Allocation Working Party to the analysis of the distribution of general medical practitioners, the relevant Family Practitioner Committee (FPC) populations were weighted according to known patterns of use related to specific characteristics--namely, age, sex, marital state, and socioeconomic group. Comparative weightings were also calculated using standardised mortality ratios. Adjusting the populations to take account of differential use has relatively little impact on national variations in list sizes but an appreciable effect on particular FPCs, notably East and West Sussex, Dorset, and the Isle of Wight. Inequalities in the distribution of general practitioners are increased considerably, however, if figures taking account of the inflation of list sizes and cross-boundary flows are used. To formulate and monitor policy about the distribution of general practitioners more sensitive measures of population and its likely demand for services must be developed.

A cross-cultural study of cognitive development.

This Monograph summarizes a comparative study of recall memory among children from two Guatemalan towns and one American city. The age interval of greatest improvement in serial recall of pictures, words and orientations of dolls varied across settings by as much as 4-6 years, but performance improved with age in all communities. It was suggested that the activation of varied strategies to aid recall memory emerged in all children during the preadolescent years, but environmental factors, as yet unspecified, determined both the slope of the growth function and its asymptotic level.

Functional classification of undernourished populations in the Republic of El Salvador. Methodological development.

Typical government nutrition programmes usually lack precise information on the size of groups that could benefit from interventions, on the different types of potential beneficiaries and their location, and on socio-economic and cultural characteristics through which they could readily be identified. In the functional classification approach to the definition of nutritional problems, detailed information on human behaviour and social constraints is collected at family and community levels. The data are then interpreted in general terms in order to understand how these factors contribute to inadequate levels of nutrition within larger groups. This new approach should enable more effective measures for reducing the numbers of those living under conditions of deprivation to be presented to planners and decision makers.
