Maternal Behaviors during Pregnancy Impact Offspring Obesity Risk

الملخص EN

This study investigated the effects of maternal changes during pregnancy in diet, exercise, and psychosocial factors on offspring weight parameters at birth and 6 months.

In overweight/obese (OW/OB; n=132) mothers, greater % kcal from sweets early in pregnancy was the strongest, independent predictor of higher weight for age (WFA) (beta =0.19; P=0.004), higher odds of macrosomia (OR = 1.1 (1.0–1.2); P=0.004) andWFA >90th percentile at birth (OR = 1.2 (1.1–1.3); P=0.002) and higher WFA at 6 months (beta =0.30; P=0.002).

In normal weight (n=153) mothers, higher intake of soft drinks was the strongest predictor of higher offspring WFA at birth (beta = 0.16; P=0.04) but not at 6 months.

Prenatal physical activity, depressive symptoms, and sleep-related variables did not significantly predict offspring weight outcomes.

Mothers’ eating behaviors during pregnancy, especially intake of sweets in OW/OB mothers, may have a lasting effect on child weight.
