Weight gain variation in infants of an impoverished community: Bellanse, Haiti
1Department of Epidemiology, Institute of Hygiene and Epidemiology, Brussels, Belgium.
Insights
Maternal understanding of the 'Road to Health' chart significantly improves infant weight gain in developing countries. Full vaccination and two-parent families also positively impact child growth.
Area of Science:
- Pediatrics
- Public Health
- Nutrition
Background:
- Infant growth faltering is a critical challenge in developing nations.
- Monitoring infant weight gain is essential for early detection of growth issues.
Purpose of the Study:
- To investigate factors associated with adequate infant weight gain.
- To identify preventable factors influencing infant growth trajectories.
Main Methods:
- A longitudinal cohort study of 354 rural infants over 18 months.
- Weighted multiple linear regression analysis was used to assess associations.
- Data collected included infant weight, maternal understanding of the 'Road to Health' chart, vaccination status, and family structure.
Main Results:
- Maternal comprehension of the 'Road to Health' chart was associated with significantly higher weight gain up to 6 months (123 g/month) and between 6-23 months (31 g/month).
- Infants fully vaccinated by 11 months showed higher weight gain (28 g/month) compared to unvaccinated infants.
- Infants from two-parent families had greater weight gain (47 g/month) than those from single-parent families.
Conclusions:
- Maternal understanding of growth monitoring tools like the 'Road to Health' chart is crucial for promoting adequate infant weight gain.
- Childhood vaccination and stable family environments are important determinants of healthy infant growth.
Abstract:
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.
