Age at Starting Solid Foods Affects Risk for High BMI at 1 Year

Longer duration of breast-feeding and introduction of solid foods at 5 to 6 months are associated with reduced odds of above-normal body-mass index at age 1 year.

Researchers in Australia assessed the association between duration of breast-feeding, age at introduction of solid foods, and risk for above-normal body-mass index (BMI) at age 1 year. Of 3153 infants in the study, 4.7% had above-normal BMI at 1 year.

Compared with infants with normal BMI, those with above-normal BMI were more likely to be boys and to have a higher birth weight, younger mothers, and mothers who smoked. Any breast-feeding for >3 months and full breast-feeding for ≥4 months was associated with lower odds of above-normal BMI at 1 year. Breast-feeding for <2 months was associated with introduction of solid foods before 4 months. Compared with introduction of solid foods at 6 months, introduction before 4 months and after 7 month…
