Age at Introduction of Solid Food and Obesity Throughout the Life Course

Year: 2018

Type: article

Abstract: OBJECTIVE: This study aimed to examine the association between age at solid food (SF) introduction and obesity throughout the life course. METHODS: Among 31,816 mother- nurse daughter dyads in the Nurses' Mothers' Cohort Study and the Nurses' Health Study II, information was collected on age at SF introduction, body somatotype at ages 5 and 10, and Body Mass Index at age 18 and in adulthood. Odds ratios (ORs) and 95% confidence intervals (95% CIs) for obesity throughout life were estimated using logistic regression models with adjustment for parental and nurse daughter covariates. RESULTS: Nurse daughters introduced to SF at ≥ 9 months versus 6 to 9 months had marginally higher age-adjusted (OR: 1.21; 95% CI: 1.01, 1.47) and covariate-adjusted (OR: 1.22; 95% CI: 1.01, 1.47) odds of obesity at age 5. Age at SF introduction was not related to obesity at ages 10 and 18 or in adulthood. CONCLUSIONS: Late age at SF introduction was marginally associated with obesity at age 5, but this association did not persist throughout the life course.
