RESUMO
Maintaining adequate growth remains one of the most difficult tasks for infants in developing countries. A cohort of rural infants (n = 354), median age four months, were weighed every 6-7 weeks over an 18-month period. Some 179 infants (51%) with weight information over at least 12 months were included in the study. The association between weight gain up to 6 months of age, and between 6 and 23 months of age, and factors amenable to prevention were assessed using weighted multiple linear regression. Infants whose mothers understood the 'Road to Health' chart had a weight gain that was 123 g/month (95% confidence interval (CI): 2-245) higher up to six months of age and 31 g/month (95% CI: 6-57) higher between 6 and 23 months of age compared to infants whose mothers did not seem to understand the chart. The weight gain between 6 and 23 months was also 28 g/month (95% CI: 3-54) higher for infants fully vaccinated at 11 months compared to not fully vaccinated children. It was 47 g/month (95% CI: 16-78) higher for infants living in two-parent families compared to children of a single-parent family. The results of the study suggest that maternal comprehension of the 'Road to Health' chart may contribute to more adequate weight gain.

Infants whose mothers understood the "Road to Health" chart had a weight gain that was 123 g/month (95% confidence interval [CI]: 2-245) higher up to 6 months of age and 31 g/month (95% CI: 6-57) higher between 6-23 months of age compared to infants whose mothers did not seem to understand the chart. The weight gain between 6-23 months was also 28 g/month (95% CI: 3-54) higher for infants fully vaccinated at 11 months compared to not fully vaccinated children. It was 47 g/month (95% CI: 16-78) higher for infants living in 2-parent families compared to children from a single-parent household. The results of the study suggest that maternal comprehension of the "Road to Health" chart may contribute to more adequate weight gain.
