(HealthDay News) — Maternal gestational weight gain and post-delivery weight gain are independently associated with a child’s weight development, according to a study published in Pediatrics.
Lenie van Rossem, PhD, from the University Medical Center Utrecht in the Netherlands, and colleagues used data from 3,367 children participating in a birth cohort starting in 1996 to examine the correlation of gestational weight gain and post-delivery weight change with a child’s weight development. Data on weight and height were self-reported; gestational weight gain was classified as inadequate, adequate, and excessive.
The researchers found that there was higher BMI z score and overweight prevalence throughout childhood for children of mothers with excessive gestational weight gain (OR=1.20; 95% Cl, 0.99-1.46). Compared with children of mothers with a low (<0.5 kg/year) post-delivery weight gain, children of mothers with high (≥1 kg/year) post-delivery weight gain had a 0.14 higher change in BMI z score between age 1 and 14 years.
The highest BMI z score and overweight risk at age 14 were seen for children of mothers with excessive gestational weight gain in combination with high post-delivery weight gain (OR=3.53; 95% CI, 1.70-7.33).
“Maternal [gestational weight gain] and post-delivery weight gain contribute to child’s weight development up to adolescence independently,” the researchers wrote.
