Objective: To assess the impact of health worker training on improving infant feeding practices on the daily energy intake and adiposity in children at ages 6 months, 12 months, 3 years and 6 years.
Methods: Cluster-randomized field trial conducted in Porto Alegre, South of Brazil. Health care centers were randomized into intervention (n=9) or control (n=11) sites. In intervention sites only, health workers received training based on the Brazilian National Policy "Ten Steps for Healthy Feeding for Children from Birth to Two Years of age". Interviewers visited the health care centers of both groups in order to identify pregnant women who were in the last trimester of pregnancy. All women were candidates to receive nutrition guidance through health workers from delivery to first two years of their babies. Fieldworkers blinded to treatment allocation assessed dietary and anthropometric data ages 6 months, 12 months, 3 years and 6 years.
Results: Among the 633 children underwent assessment at age 6 months, 545 underwent assessment at age 12 months, 476 underwent assessment at age 3 years, and 382 underwent assessment at age 6 years. The mean of daily energy intake was significantly lower in the intervention group at age 3 years (1454.1±19.1kcal versus 1546.6±34.2kcal; P=0.03). At age 6 years, children from intervention group presented lower values in waist circumference (55.22±0.40 versus 56.58±0.80; P=0.04), and triceps and subscapular thickness skinfold(11.56±0.26 versus 12.88±0.77; P=0.04 and 7.77±0.34 versus 9.11±0.80; P=0.04, respectively). The prevalence of overweight did not differ between groups during the entire trial (P>0.05).
Conclusion: The health workers training to promote breastfeeding and healthy complementary feeding in infants was effective in reducing adiposity indicators such as waist circumference and skinfold thickness at 6 years of age.
