Abstract
Objective: We aimed to identify factors (child diet, physical activity; maternal BMI)
associated with body composition of Ghanaian pre-school children.
Design: Longitudinal analysis of the International Lipid-Based Nutrient
Supplements (iLiNS)-DYAD-Ghana randomized trial, which enrolled 1320 pregnant
women at ≤20 weeks’ gestation and followed them and their infants until
6 and 18 months postpartum, respectively. At follow-up, child age 4–6 years, we
collected data on body composition (by 2H dilution), physical activity and diet,
extracted dietary patterns using factor analysis, and examined the association of
children’s percentage body fat with maternal and child factors by regression
analysis.
Setting: Eastern Region, Ghana.
Participants: Children 4–6 years of age.
Results: The analysis included 889 children with percentage body fat and dietary
data at follow-up. We identified two major dietary patterns, a snacking and a
cooked foods pattern. Percentage body fat was positively associated (standardized
β (SE)) with maternal BMI at follow-up (0·10 (0·03); P = 0·003) and negatively associated
with physical activity (−0·15 (0·05); P = 0·003, unadjusted for child gender),
but not associated with the snacking (0·06 (0·03); P = 0·103) or cooked foods
(−0·05 (0·07); P = 0·474) pattern. Boys were more active than girls (1470 v.
1314 mean vector magnitude counts/min; P < 0·0001) and had lower percentage
body fat (13·8 v. 16·9 %; P < 0·0001).
Conclusions: In this population, maternal overweight and child physical activity,
especially among girls, may be key factors for addressing child overweight/
obesity. We did not demonstrate a relationship between the dietary patterns
and body fatness, which may be related to limitations of the dietary data available.
