Social Interactions of Guatemalan Infants
The behavior of 52 rural Guatemalan infants of ages 8, 12, and 16 months was observed and recorded in their homes. Most interactions initiated by the caretaker seemed to consist largely of caretaking activities, and a relatively large verbal component was evident only with increasing age. Specific caretakers were associated with specific types of social interactions. The mother was the primary caretaker, being responsible for most of the carrying…
Energy intake and growth in an energy deficient population
The relationship between energy intake and growth rates in height and weight was investigated in 190 Guatemalan children. Intake of a protein‐energy, but not of an energy supplement, was significantly related to growth. However, the effect per calorie was similar for both types of supplements. Further, when the sample was pooled, the above relationship was not altered by the presence of protein in the supplement nor by sex, home dietary intake, m…
Effect of moderate maternal malnutrition on the levels of alkaline ribonuclease activity in the human placenta
Ribonuclease (RNAse) activity was measured in placentas from a sample of 49 urban Guatemalan women from low (30) and high (19) socioeconomic status (SES). Low SES women had a larger proportion (40%) of high levels of RNAse (> 60,000 units/g) than women from the high SES group (5 %). A trend to inverse association (p = 0.06) was also observed between amount of supplemented food energy during pregnancy and RNAse activity in rural populations covere…
Stature and age as factors in the growth of second metacarpal cortical bone in moderately malnourished children
The association of stature and age with measures of second metacarpal cortical bone growth is investigated in a sample of 1586 radiographs taken from Guatemalan Ladino children aged 1-7 years in a setting of endemic mild-to-moderate malnutrition. For given stature, chronological age is positively associated with cortical thickness and cortical area and negatively associated with periosteal and medullary diameter. These different partial correlati…
Relations between nutrition and cognition in rural Guatemala
The nutritional status of three and four year old children, as measured by height and head circumference, is related to cognitive performance in four rural Guatemalan villages. The relationships persist when social factors are taken into account. Families in two of the villages participate in a voluntary, high protein-calorie supplementation program. In the other two villages, the families receive a vitamin and mineral supplement with one-third o…
Effect of morbidity during pregnancy on birth weight in a rural guatemalan population
The high prevalence of low birth weight (≤ 2.5 Kg) babies is a major public health problem in many poor communities. Studies in humans suggest that malnutrition during pregnancy is an important factor in accounting for this problem, but almost no information is available about the effect of common maternal diseases during pregnancy. This paper reports the effects of maternal morbidity during pregnancy on birth weight in four rural villages of Gua…
Sexual dimorphism in bone growth as a function of body size in moderately malnourished Guatemalan preschool age children
The sexual dimorphism in second metacarpal bone growth was investigated in 710 malnourished Guatemalan children one to seven years old to determine if the sex differences seen are only the result of differences in stature and weight. The study sample was mixed‐longitudinal and consisted of 1,586 annual examinations. Boys have greater mean stature, weight, periosteal diameter, medullary diameter and cortical area than girls the same age, while gir…
Traditionalism and Field Dependence
The relationship between preschool children's field dependence-independence and mothers' traditionalism and intellectual stimulation provided in the home was investigated in rural Guatemala. Contrary to several previous studies-which have not measured traditionalism at the level of the family, but rather compared children from more and less traditional communities-EFT scores were found to be unrelated to traditionalism. EFT scores were related to…
Length and weight in rural Guatemalan Ladino children
The present study reports 5,029 length and weight measurements as well as percentile distributions for a mixed longitudinal series of 1,119 rural Guatemalan Ladino children. The study sample, birth through seven years, is representative of children in clinically good health, but of suboptimal nutrition. Boys are longer and heavier than girls over the age range. Guatemalan children of both sexes are smaller than American white children from Denver…
Diarrheal diseases and growth retardation in preschool Guatemalan children
The relationship between diarrheal diseases and growth increments in total body length and weight was investigated in 716 rural Ladino Guatemalan children. Data on diarrheal diseases were provided by the mothers through retrospective surveys carried out at 14‐day intervals. Increments in length and weight, semestral from near birth to four years and yearly thence to seven, were related to days ill with diarrheal diseases during the same time inte…
The identification and evaluation of measurement variability in the anthropometry of preschool children
Measurement variability estimates for 18 different anthropometric dimensions were collected within the context of an ongoing longitudinal investigation of preschool Guatemalan children. Estimates of total measurement variance, intra‐observer variance, and short‐term intra‐subject variance are presented for each variable. A simple procedure for the evaluation of measurement variance in cross‐sectional and longitudinal investigations is described i…

Preference and Recall in Serbian Cousinship
The male-oriented nature of traditional Serbian social structure, with its emphasis on agnation and male dominance, is paralleled in Serbian kinship ideology, in which recall of kinsmen and statements of preference for them are stronger for male kin and for kin through males. Women, who are largely excluded from traditional networks of political and economic power, share less in these kinship ideological biases than do men. Social mobility, parti…
Social Mobility and the Durability of Family Ties
Urbanization and industrialization are often identified as processes destructive of familial and kinship relationships. Research in Belgrade, Yugoslavia, the focus of forced-draft industrialization since 1945, shows that contacts between fathers and sons, and contacts between brothers, remain intense despite far-reaching urbanization, and geographical and social mobility. Frequency of contact is depressed more by factors of distance and inconveni…
