In this study, we aimed to establish whether domestic use of wood fuel is associated with reduced birth weight, independent of key maternal, social, and economic confounding factors. We studied 1,717 women and newborn children in rural and urban communities in rural Guatemala. We identified subjects through home births reported by traditional birth(More)
This paper reviews the usefulness of the 1-day recall method for assessing calorie and protein intake. To this end, it discusses the basic assumptions in determining nutrient intake of either populations or individuals. It is concluded that the 1-day recall survey is valid and reliable to estimate mean dietary calorie and protein intake in population(More)

The growth in arm muscle area and arm fat area of preschool children from rural Guatemala is compared to that of a standard from the U.S.A. It was found that although the Guatemalan children have reduced arm muscle and fat areas, the relative reduction in arm fat area was greater than in arm muscle area. Further, the upper arm cross-sectional area of(More)
The high prevalence of low-birthweight (less than or equal to 2,500 gm) babies in many poor communities is a major public health problem. Studies in humans in situations of acute starvation suggest an effect of maternal nutrition on birthweight, but less clear results appear under situations of moderate maternal malnutrition. We studied the effects of food(More)
380 women of parity 1 or more living in coffee plantations of the Pacific lowlands of Guatemala were studied during the 18-month period from October 1977 to March 1979 to investigate the relationship between maternal stature, parity, offspring mortality, and number of surviving children. Average height was 142 cm or 4 feet 8 inches, average age was 28(More)
A total of 2192 articles published in the international literature with UNAM (National University of Mexico) first author affiliation and registered by the CICH (Centro de Iformación Científica y Humanística) BIBLAT database from 1978-mid-1987 were included in our analysis. Distribution of articles according to the main subject areas of the 692 different(More)
This paper discusses some conditions necessary to detect an effect of maternal nutrition on birth weight and the relative contribution of calories and protein to such an effect. The expected dose- and time-response relationships for nutritional interventions aimed at the improvement of birth weight are also discussed. There appears to be a minimal level of(More)
Studies of seasonality and growth from developed nations demonstrate distinct effects on weight and height gains according to the season. When maximal group gains in height are recorded, minimal weight gains are detected. Only a quarter and a third of all children had their minimal and maximal height gains respectively, in the same period as minimal and(More)
