Nutrition counseling increases weight gain among Brazilian children.

To assess the impact on child growth of the nutrition-counseling component of the Integrated Management of Childhood Illnesses (IMCI) strategy, a randomized trial was implemented. All 28 government health centers in a Southern Brazil city were paired according to baseline nutritional indicators. One center from each pair was randomly selected and its doctors received 20-h training in nutrition counseling. Thirty-three doctors were included and 12-13 patients < 18 mo of age from each doctor were recruited. The study included testing the knowledge of doctors, observing consultations and visiting the children at home 8, 45 and 180 d after the initial consultation. Maternal knowledge, practices and adherence to nutritional recommendations were assessed, and anthropometric measurements were taken. Day-long dietary intake was evaluated on a subsample of children. Doctors in the intervention group had better knowledge of child nutrition and improved assessment and counseling practices. Maternal recall of recommendations was higher in the intervention than in the control group, as was satisfaction with the consultation. Reported use of recommended foods was also increased. Daily fat intake was higher in the intervention than in the control group; mean daily intakes of energy and zinc also tended to improve. Children 12 mo of age or older had improved weight gain and a positive but nonsignificant improvement in length. Nutrition-counseling training improved doctors' performances, maternal practices and the diets and weight gain of children. The randomized design with blind outcome evaluation strongly supports a causal link. These results should be replicated in other settings.

The role of care in nutrition programmes: current research and a research agenda.

The importance of cultural and behavioural factors in children's nutrition, particularly with regard to feeding, has been recognized only recently. The combination of evidence regarding the importance of caregiving behaviour for good nutrition, and improved strategies for measuring behaviour have led to a renewed interest in care. The UNICEF conceptual framework suggests that care, in addition to food security and health care services, are critical for children's survival, growth and development. The present paper focuses on the care practice of complementary feeding, specifically behavioural factors such as parental interaction patterns, feeding style and adaptation of feeding to the child's motor abilities (self-feeding or feeding by others). Three kinds of feeding styles (Birch & Fisher, 1995) are identified: controlling; laissez-faire; responsive. Probable effects of each feeding style on nutrient intake are described. A number of studies of feeding behaviour have suggested that the laissez-faire style is most frequently observed among families and communities with a higher prevalence of malnourished children. Nutrition interventions that have been able to show significant effects on outcomes, such as the Hearth Model in Vietnam (Sternin et al. 1997), have usually incorporated behavioural components in their intervention. At this time, there have been no tests of the efficacy of behavioural interventions to improve feeding practices. Research is needed to understand behavioural factors in complementary feeding, and to identify and test intervention strategies designed to improve nutrient intake of young children. Finally, the paper concludes with a discussion of how nutrition programmes might change if care were incorporated.

Care for nutrition and development.

Optimal growth and development depend not only on food quality and availability, on access to health care services and a healthy environment but also on the care provided to the child especially during the first few years of life. Care refers to the actions and practices of caregivers on a day to day basis that translate food, heakh care, and water and sanitation supplies into good growth and development of children. It includes behaviours such as feeding, sanitation and hygiene, home health practices, preparing food for children, and providing psychosocial support for development. Families also are responsible for providing care for girls in the family and women. Care requires resources--both skills and capabilities, as well as economic resources. Some resources are easily recognised, such as education of the caregiver, but others are less often seen, including time of the caregiver, motivation of caregiver and male family members, organisational resources such as child care centres, and the caregiver's ability to influence decisions about child care. It must be noted that the poorer the family, the more risks for children in the environment. Therefore, the poorer the environment, the more important a role care has in children's survival, growth and development. Implications for health care providers include assessing the care practices in the home, and resources for care when making recommendations; supporting positive practices already being performed in order to empower the caregiver; checking the understanding and recall of the caregiver; and finally, recognising that all children, regardless of gender, ethnicity, case, economic level, etc, have a right to good nutrition and health care in order to develop to their fullest potential under the Convention for the Rights of the Child, acceded to by India in 1992.

Research steps in the development and evaluation of public health interventions.

Presented is a conceptual framework for planning intervention-related research. Altogether, nine steps in the process of developing and evaluating public health interventions are specified. This process is dynamic and iterative, and all steps are not always required, or need follow in sequence. The framework can be used to set research priorities by verifying where there is sufficient knowledge to move forward and by identifying critical information gaps. It can also help select appropriate research designs, as each step is characterized by certain types of studies. Greater effort is required to move beyond descriptive epidemiological and behavioural studies, to intervention studies. Field trials of public health interventions require particular attention as they are often neglected, despite their significance for public health policy and practice.

Theory-driven behavioral intervention research for the control of diarrheal diseases.

Essentially all methods to reduce diarrheal morbidity and mortality require behavioral change. Research is required to design, implement and evaluate behavior-modifying interventions. Accumulated experience in the many involved disciplines should serve as a basis for this research. However, each of these disciplines is associated with different research perspectives and analytic assumptions; thus integration of these varied but potentially complementary experiences has been elusive. In the present paper, arguing that such perspectives and assumptions are embodied in discipline-based theory, we have developed a generic framework for the conduct of theory-based behavioral intervention research. We illustrate the application of this framework through two vignettes applying two of the theories and models to the development of hypothetical handwashing interventions.

[Nutrition and development in the first semester of life].

OBJECTIVE: To study the psychomotor development of young infants from a poor and underfed rural community and to correlate this with the nutritional conditions of the mother during pregnancy and the child itself. MATERIAL AND METHODS: We studied 82 mother-child pairs from the 5th month of pregnancy to the 6th month of life of the child as to anthropometry and food consumption. The neonatal Brazelton test and the Bayley test at 3 and 6 months were applied to the child. RESULTS: Several of the neonatal psychomotor tests applied to the child correlate positively with the mother's weight and skin folds, as well as with the child's own previous weight and size. This was also true for maternal consumption of animal foods and fruits during pregnancy. A negative correlation was observed with the consumption of corn tortillas and beans. The correlation of several tests applied to the child at six months was positive with its complementary consumption, total energy and several foods, specially egg, milk and fruit around three months of age. CONCLUSIONS: Small variations in nutrition of the mother-child pairs from the poor rural community studied had consequences on the psychomotor development of the infant. These findings point to the need for more applied nutrition programs.
