Abstract
This study aimed to examine the association between breastfeeding and childhood
obesity. A multinational cross-sectional study of 4,740 children aged 9–11 years was
conducted from 12 countries. Infant breastfeeding was recalled by parents or legal
guardians. Height, weight, waist circumference, and body fat were obtained using
standardized methods. The overall prevalence of obesity, central obesity, and high
body fat were 12.3%, 9.9%, and 8.1%, respectively. After adjustment for maternal
age at delivery, body mass index (BMI), highest maternal education, history of gestational
diabetes, gestational age, and child's age, sex, birth weight, unhealthy diet pattern
scores, moderate-to-vigorous physical activity, sleeping, and sedentary time,
exclusive breastfeeding was associated with lower odds of obesity (odds ratio
[OR] 0.76, 95% confidence interval, CI [0.57, 1.00]) and high body fat (OR 0.60, 95%
CI [0.43, 0.84]) compared with exclusive formula feeding. The multivariable-adjusted ORs based on different breastfeeding durations (none, 1–6, 6–12, and > 12 months)
were 1.00, 0.74, 0.70, and 0.60 for obesity (Ptrend = .020) and 1.00, 0.64, 047, and
0.64 for high body fat (Ptrend = .012), respectively. These associations were no longer
significant after adjustment for maternal BMI. Breastfeeding may be a protective factor
for obesity and high body fat in 9- to 11-year-old children from 12 countries.
