Maternal employment, child care, and nutritional status of 12-18-month-old children in Managua, Nicaragua.

Relationships among women's employment, child care strategies, and nutritional status of children 12-18 months of age were examined in 80 Nicaraguan households sampled by randomized block design in 10 low income urban communities. Multiple regression analyses showed that children of employed mothers (56%) fared better in weight/height than those whose mothers were not employed, with and without controlling for socioeconomic status and maternal education, paternal financial support, child care adequacy, and sex and age of the child. Children with inadequate alternate child care (care by a preteen or care at the work place) had lower height for age, even controlling for the same variables and for maternal employment. Differences in 10 caregiving behaviors between families as a function of work status of the mother and adequacy of child care were examined. In families with working mothers, caregivers were less likely to be observed washing their hands, suggesting that the positive associations of work for earnings might be due to income rather than improved care. Inadequate care was associated with less food variety, less use of health care, and marginally less hand-washing. Inadequate child care, which tends to be associated with informal work, nuclear families and poverty, should be a concern for child welfare.

Nutritional correlates of frequency and length of breastfeeds in rural Bangladesh.

In this rural Bangladeshi sample of 165 mothers and their breastfed infants aged 5-23 months, mean maternal body mass index (BMI) was 18, and 12-month infant height-for-age z-scores (HAZ), -2.35. Structured observations were conducted over 6 months on 1649 breastfeeds during 3324 weekly daytime observations. Infants' and mothers' 24-h dietary recalls, weights, lengths/heights and mothers' arm circumferences were taken monthly. When plotted with age, infants' anthropometric z-scores, food energy, and minutes observed breastfeeding revealed three patterns in age periods: 5-12, 13-18, and 19-23 months. In periods one (breastfeeding high) and three (breastfeeding low), food energy increased with age, linear growth paralleled the World Health Organization (WHO) reference standard, and the children grew thinner. In two, (breastfeeding declining), food energy did not increase and growth stasis occurred. Longer observed breastfeeding accompanied in period one, low maternal arm circumference, low infant energy intake from complementary foods and infant shortness and plumpness in period two, infant shortness, thinness, and underweight; and in period three, infants energy and thinness. In conclusion, the paper suggests that growth stasis occurs primarily during the second period, which should have highest priority for culturally sensitive interventions.

Developmental, behavioural, and environmental risk factors for diarrhoea among rural Bangladeshi children of less than two years.

One hundred and eighty-five rural Bangladeshi children (80 boys and 105 girls) aged 4-27 months were observed to investigate developmental, behavioural, and environmental risk factors for diarrhoea during a 6-month period. Incidence of diarrhoea was found to be the highest among children aged 10-12 months. Children of this age group had the greatest exposure to environmental contaminants in the neighbourhood. Incidence of diarrhoea was the highest in hot, dry months. Risk factors for diarrhoea included: faecal contamination and garbage disposal in infant's outdoor play compound, crawling, contact of hand and mouth with contaminated materials, greater distance of household from water source, inadequate cleaning after defecation; dirt of child's face, presence of flies, feeding rotten food; insufficient washing of infant's and caretaker's hands before feeding rice meals or soft, wet foods; and lack of mothers' willingness to visit a modern (allopathic) health practitioner.

Maternal education and child feeding practices in rural Bangladesh.

This study in rural lowland Bangladesh used spot and event observations from 185 children aged 4-27 months in order to examine whether child feeding practices differed with mother's education and with household education. Each child and his/her caretakers were observed for a mean of 20 hr over 6 months from February to July 1986. Only 25% of mothers and 51% of fathers had had any formal education. Exploratory partial correlations and stepwise multiple regression analyses revealed significant behavioral differences with both maternal and household measures of education while controlling for wealth. Caretakers in families with education were found to feed the children more frequently, with fresher food, and in cleaner, more protected places. They did not allow their children to eat food intended for someone else as often, and were more observant when their children's food dropped during the feeding. These caretakers also used more cups and bottles for feedings, breastfed their children less frequently, and their mothers terminated the breastfeedings more often. These behaviors suggested a shift from less attentive feeding practices and less frequent feedings to more frequent feedings in which the caretaker took more control of the child's feeding sessions. They also suggest a commitment to more labor-intensive child care. These associations between education and child feeding practices are mechanisms through which maternal education may improve child health and growth. They suggest the need for promoting more formal and nonformal education.

A longitudinal study of the impact of behavioural change intervention on cleanliness, diarrhoeal morbidity and growth of children in rural Bangladesh.

A community-based intervention was developed through direct participation of the target population in assessment and iterative trials to improve hygiene practices and to reduce childhood diarrhoea in lowland rural Bangladesh. A total of 185 (98%) households with children ages 0-18 months in five contiguous villages were targeted for the interventions. A comparison site was selected for a detailed observational study and for use as a control for the intervention. About 97% of all households with children ages 0-18 months were enrolled for study at the control site. Children in this age group were targeted because at this developmental stage they were most vulnerable to diarrhoeal morbidity and malnutrition (related to unhygienic practices). The intervention was implemented with the assistance of village leaders through a "Clean Life" campaign by local project workers and volunteer mothers who were chosen from the target households. The intervention activities started in January 1986 and lasted for 7 months. Higher adoption rates of the intervention were associated with better cleanliness status, which was related to lower diarrhoea and malnutrition rates in the intervention site. The results of between-site longitudinal analyses showed that after the intervention, the intervention site had substantially higher cleanliness scores, lower diarrhoeal morbidity, and better growth status compared to those of the control site, with differences increasing over time. The findings suggest that this type of community-based intervention can be very beneficial in modifying hygiene behaviours and lowering childhood diarrhoea and malnutrition.

Comparison of the costs of compliance with nutrition education messages to improve the diets of Bangladeshi breastfeeding mothers and weaning-age children.

Local market prices in rural Bangladesh were used to compute the costs of filling the nutrient gaps between actual intakes and safe nutrient requirements, and the costs of compliance with nutrition messages, for 78 lactating mothers and 61 weaning-age breastfed children. (The gap is the difference between the requirement and the amount of nutrient consumed.) To fill the mother's energy gap of approximately 1050 kcal (4393 kJ) would cost an additional 21% of the daily wage, or almost double the value of food she was presently eating. Given social reality, these costs would probably be much greater, as the mother would also need to increase the allocation of food to other household members. The weaning-age children's energy gap could theoretically be closed for less than one-third of the cost of improving the mothers' diets, or about 8% of the daily wage. The increase in food intake equivalent to 2% of the daily wage actually achieved through nutrition education resulted in a significant improvement in child weight gain, though not ideal. These findings suggest that, in the absence of programs which reduce economic barriers, it is economically feasible for families to close the nutrient gaps for weaning-age breastfed children in Bangladesh, but not for lactating women. Thus, education to improve women's diets should be incorporated into programs that make these improvements affordable, whereas education to improve weaning-age children's diets can be implemented with or without other program supports.

Mothers' and children's intakes of vitamin A in rural Bangladesh.

The vitamin A intake of 370 mothers and 183 children 3-27 mo of age in rural Bangladesh was ascertained monthly from January to July in 1986. For mothers, dark green leafy vegetables and fruits were the main sources of vitamin A. Vitamin A from vegetables, the single most important source, did not show consistent associations with wealth or with the other socioeconomic indicators. In May and June, fruits provided wealthier (and more educated) mothers with significantly higher vitamin A intakes than poor mothers, whereas in January the poorer mothers had higher intakes. When breast milk was included, average intakes for children came close to 100% of the recommended dietary allowance; the only other significant source of vitamin A for children was seasonally available mangoes. Fourteen children who had stopped breast-feeding by the end of the study were at very high risk of vitamin A deficiency when fruits were not plentiful.

Evaluation of the impact of weaning food messages on infant feeding practices and child growth in rural Bangladesh.

In rural Bangladesh, a community-based weaning intervention used volunteers to teach complementary feeding to families of 62 breast-fed infants aged 6-12 mo. Over 5 mo, treatment children gained on average 0.46 SD (approximately 460 g) more in weight-for-age (WAZ) than the 55 control subjects, and were approximately 0.5 kg heavier at the final measure. The differences were statistically significant (P < 0.001). The percent median weight-for-age (WAPM) of treatment children held steady at 76% of the National Center for Health Statistics' reference, whereas the WAPM of control subjects dropped from 78% to 72%. The increase in percentage points of severe malnutrition (below -3 WAZ) was only 5% in the treatment group compared with 26% in the control subjects. Treatment children consumed a significantly greater percent of their energy and protein requirements from complementary foods than did control subjects. The affordable complementary foods consisted mainly of cereal porridge with oil and brown sugar. These findings suggest that educational interventions teaching families to feed hygienic, simple, cheap, energy-enriched complementary foods to breast-fed infants after 5-6 mo can improve child growth, even under impoverished conditions.

Field validation of the Tallstick in marginal communities in Nicaragua.

The Tallstick is a new, simplified anthropometric field tool which allows immediate visual interpretation of height-for-age. This tool was field tested in community-based programmes in Managua, Nicaragua, and the rural community of Los Zarzales, screening 1004 children aged 0-60 months for nutritional stunting. Overall sensitivity and specificity analysis comparing HAZ scores and Tallstick results revealed that the Tallstick correctly identified 83-85 per cent of severely stunted children (HAZ < -2.5) and two-thirds of those with HAZ of -2 and below. It also had good positive predictive value for the mildly stunted. As a screening tool for low weight-for-age, the Tallstick performed better than arm circumference. The best of the community volunteers trained with the Tallstick could use it as well as their trainers. Progressive stunting was found in the 280 children in the sample who did not receive any form of milk. The advantages of the Tallstick for community-level screening and the importance of sustained linear growth are discussed.

Nutrition and behavioral characteristics and determinants of plasma cholesterol levels in men and women.

The National Cholesterol Education Program advocates dietary interventions in persons with high and moderate blood cholesterol levels and in the general population as a preventive measure for coronary heart disease. For these efforts to be successful, it is necessary to understand consumer characteristics and behaviors, including nutrient intake and dietary patterns. We studied the relationship of plasma cholesterol levels to consumer characteristics and dietary behaviors by examining 127 men (aged 20 through 71 years) and 187 women (aged 18 through 67 years) as part of a cholesterol screening project in the administrative offices and academic departments of Boston University from March 1988 through June 1988. Our results showed that specific consumer characteristics and dietary behaviors significantly differentiated male and female groups with low, moderate, and high cholesterol levels. Factors that should be considered in planning dietary interventions aimed at cholesterol reduction in men include spouse involvement and support in lipid-lowering interventions; weight reduction; increase in exercise; reduction in beef intake; and increases in dietary fiber and carbohydrates, particularly fruits. For women, recommendations include weight reduction; possible interventions aimed at reducing blood pressure (ie, behavioral modification aimed at reducing stress, increasing exercise, and cooking low-salt meals); reduction in beef intake, dietary fat, and saturated fat; and increases in carbohydrates and dietary fiber.
