Stupidity or worms
Stupidity or worms
The title of a 1930s article asked the question, "Stupidity or Hookworm?" In this article, the authors discuss research that attempts to answer the question of whether intestinal worms--namely, hookworm, whipworm, and roundworm--harm the mental performance of their hosts. After introducing the biology and epidemiology of intestinal worms, the authors present the historical background to the problem. They review research from the 1910s through the…

Stunting and delayed motor development in rural West Java
The association between physical growth and gross motor development, particularly self‐produced locomotion, was considered in 557 children 3–18 months of age. Gross motor development was assessed with nine preselected milestones representing the major landmarks in self‐produced bipedal locomotion. Motor development is presented by age and by milestone, and is compared to developmental ranges of the Denver Developmental Screening Test. Consistent …
Infant feeding policies in maternity wards and their effect on breast-feeding success
OBJECTIVES. The purpose of this review is to examine the plausibility of a causal relationship between maternity ward practices and lactation success. METHODS. Studies were located with MEDLINE, from our personal files, and by contacting researchers working in this field. Of the 65 studies originally reviewed, 18 met our inclusion criteria (i.e., hospital-based intervention, experimental design with randomization procedures, or quasi-experimental…

Seasonality and weight gain during the first year of life
A comparison is made between weight increments at 0–3, 4–6, 7–9, and 10–12 months of life between infants born in the fall, winter, spring, and summer seasons in Sui Lin, Taiwan. The focus of the study is on (1) whether in a tropical region the effects of seasonality on weight gain interact with the developmental stage of the infant and (2) whether these interactions are partly regulated by the growth history of the infant. The main hypothesis is…
Effects of WIC on cognitive development
the October issue of the American Journal of Public Health, reported significant differences in behavioral and intelligence test measures between children with different time periods of participation in the National Special Supplemental Food Program for Women, Infants, and Children (WIC) program.' The sample was restricted to 21 pairs of siblings; the oldest was enrolled in the program after the first year of life and participated for 30.8 months…
Seasonal variation in pre‐ and postpartum maternal body measurements and infant birth weights
A sample of 225 rural Taiwanese women were followed longitudinally through two successive pregnancy and lactation periods. Maternal pre‐ and postpartum weight and skinfold thicknesses and infant birth weights showed considerable seasonal variation. The lowest mean maternal weights, irrespective of pregnancy or lactation status, occurred in the summer months of June, July, and August, when temperatures and rainfall reach their yearly maxima. The l…
The Bacon Chow study
Estimates of the prevalence of energy–protein malnutrition almost universally employ physical growth measurements. In this study we focus on this disease and the role of body size of relatives as mediators of responses in individuals to one type of nutrition intervention: supplementation of pregnant and lactating women. In this study, initiated by Dr. Bacon Chow and others in 1967, during gestation of a first infant a mother was untreated, while …
Educational benefits of the United States school feeding program
In the Child Nutrition Act of 1966 it was stated that educational progress was an objective of the United States School Feeding programs. In spite of this fact no serious attempt has ever been made to evaluate whether this objective has been met; the few evaluations that have been conducted lack scientific rigor. As a whole the studies fail to provide a strong basis from which to make valid inferences regarding the long-term effects of the feedin…
Psychosocial development and behavior of mothers of failure-to-thrive children
The social development, emotional adaptation, and functioning of mothers of failure-to-thrive children, and of a group of matched controls were studied. Results show that maternal behavior of the mothers of the failure-to-thrive groups, while showing no overt psychopathology, did differ substantially from that of the control group
Ecology, Malnutrition, and Mental Development
In this paper an attempt is made to show how, in the published behavioral studies of protein-calorie malnourished children, a methodological disregard for the ecology of malnutrition has not made it possible to determine the nature of the children's poor performance in the developmental tests used. Such performance could have been mediated by biochemical disorders resulting from nutritional deficiency, by biological and social factors coexisting …
Biological and social correlates of stature among children in the slums of Lima, Peru
A study of a sample of children with constrasting stature from the slums of Lima, Peru showed that the short children were more likely to have shorter mothers, who had had more pregnancies, less years of schooling, and a greater number of marriages. The results, reported here, suggest that although differences in stature might reflect differences in nutritional background, they are also likely to reflect differences in other important biosocial f…
