Effects of New Complementary Feeding Guidelines on Eating Behaviour, Food Consumption and Growth in Colombian Children: 6-Year Follow-Up of a Randomised Controlled Trial

TL;DR

A 6-year follow-up study in Colombia found that new complementary feeding guidelines had lasting effects on children's eating behaviors and food consumption, but not on growth outcomes.

Contribution

This study provides long-term insights into the effects of new complementary feeding guidelines on eating behavior and food consumption in children.

Findings

Children in the control group had higher weekly chocolate milk drink consumption and higher food responsiveness scores.

No significant differences in BMI Z-scores or overweight/obesity rates were found between groups at 6 years of age.

BMIZ was positively predicted by food responsiveness and negatively by red meat consumption at 12 months.

Abstract

Complementary feeding (CF) may influence later eating behaviour and growth. Our previous Randomised Control Trial (RCT) reported that new CF guidelines (NCFGs) implemented in 6–12-month-old infants in Bogota, Colombia, had positive short-term effects on red meat, vegetable and fruit consumption. Here, we assessed the effects of the NCFGs on food consumption, eating behaviour and growth at 6 years of age. Weight and height were measured using 50 children (58.8%) from the cohort. Feeding behaviour was measured using the Child Eating Behaviour Questionnaire (CEBQ) and maternal and child food consumption was measured using a semi-quantitative food frequency questionnaire. The control group (CG) had a significantly higher weekly consumption of chocolate milk drinks (p = 0.05). The mean food responsiveness (FR) score was significantly higher in the CG (p < 0.001). Although HAZ (height for age Z-score) at 6 years of age was significantly higher in the CG (p < 0.02), there was no significant difference between groups in the change in HAZ from 6 months and 12 months to 6 years of age. BMIZ (body mass index Z-score) and % overweight (CG 18.5% versus NCFG 13%) or obese (3.7% versus 0%) were not significantly different between groups. BMIZ was positively predicted by FR (β 0.293; p = 0.014) and negatively predicted by weekly red meat consumption episodes per week at 12 months (β −0.169; p = 0.020). Although there was no direct effect of an intervention on BMIZ at 6 years of age, the results were consistent with an indirect effect via intervention effects on meat consumption at an age of 12 months and FR at 6 years of age. However, further longitudinal studies with a larger sample size are needed.
