[Effectiveness of nutritional counseling provided by the Children's Mission on hemoglobin variation in under-six children].

A community intervention was conducted to evaluate the effectiveness of leadership training in the Children's Mission (of the Brazilian Catholic Church) for providing nutritional counseling on hemoglobin variation in children less than six years of age. Two areas of activity by the Children's Mission in Pelotas, Rio Grande do Sul State, Brazil, were randomly selected and the leaders in one were trained (intervention group). The other area constituted the control group. After providing consent, mothers were interviewed concerning the family and the child's health and eating. Hemoglobin was measured with a portable photometer upon entry into the study and at six months. The outcome variable was hemoglobin variation between the first and second measurements. The study included 183 intervention children and 179 controls, comparable as to sex, age, characteristics at birth, iron supply, and mean hemoglobin. In the adjusted analysis, variation in the intervention group was 0.18 +/- 0.27 g/dl greater than in the control group. Although the difference between the two groups was not statistically significant, the variation was positive in the intervention group and negative in the control group, suggesting a beneficial effect from the training.
