During longitudinal field studies of the growth, dietary intake, and morbidity from infectious diseases of children between 6 and 60 months of age in two rural villages of Bangladesh, seasonal fluctuations in growth, nutritional status, and the prevalence of malnutrition were observed. The weight, length, arm circumference, and triceps skinfold thickness of 197 children were measured monthly for 15 months and compared with sex-specific local village norms and international reference populations. The percentages of expected weight for length, arm circumference for age, triceps skinfold thickness for age, and the percentages of expected monthly increments of weight and length for age were the indicators most sensitive to seasonal changes. ⋯ The periods of greatest nutritional deficit depended on which anthrometric indicator was used to define nutritional status, but generally occurred during the monsoon and persisted until the subsequent harvest period. However, the fall in mean percentage of expected length for age and the increase in the prevalence of stunting occurred several months after the periods of greatest malnutrition identified by the other measurements. The importance of selecting the appropriate anthropometric techniques to detect seasonal changes and the implications of such changes are discussed.

This monograph has presented a review of menstrual disorders in adolescents. It has been emphasized that health care professionals who deal with youths should consider a comprehensive approach that places the youth with a menstrual problem within the framework of her adolescent and pubertal development. Thus, a discussion of psychologic growth as well as important aspects of puberty were presented. ⋯ Specific, complex situations should be referred to the appropriate specialist, preferably someone with an understanding of adolescence. Three basic types of menstrual disorders have been considered: dysmenorrhea, dysfunctional uterine bleeding and amenorrhea. Our conclusion is that there is much the general clinician can do for the adolescent who presents with menstrual dysfunction.

A cohort of all infants born between January 1, 1969 and February 28, 1977 in four rural villages in Eastern Guatemala which were participating in a longitudinal project of nutrition and mental development was studied. As part of the study, prospective information on anthropometric measurements, morbidity, dietary intake and socioeconomic and cultural characteristics was collected. In addition, two types of food supplements were distributed: calorie and protein-calorie. ⋯ We studied the effect of the supplements consumed by the mother during pregnancy and lactation and by the infant on trimestral infant weight and length changes during the first year of life. The data indicate that infant calorie supplementation before three months of age is significantly and negatively associated with infant growth; after three months of age, supplemental calories consumed by the infant are significantly and positively associated with infant weight and length gains. In addition, a small positive association was found between maternal caloric supplementation during lactation and infant growth during the first two trimesters of life, after controlling for potentially confounding factors for which data are available in this study.
