Very rarely, however, exclusively breastfed infants experience excessive weight gain (EWG) during the period of exclusive breastfeeding (EBF) when breast milk is the only source of nutrition. We investigated growth and body composition at 36 months in children experiencing EWG during EBF. <b><i>Methods:</i></b> Ten infants with EWG during the first 6 months of EBF were followed up at 36 months. The infants had been followed from age 5 months. Examinations included anthropometry, body composition by bioimpedance, and blood samples. Body composition and plasma leptin concentrations were available for eight and five children, respectively. <b><i>Results:</i></b> From 5 to 36 months, body mass index-for-age <i>z</i>-scores (BAZ) decreased from (mean ± standard deviation) 2.33 ± 0.94 to 1.48 ± 0.57, and only one child still being overweight (BAZ >2). Fat mass and fat mass index (FMI) decreased from 18 to 36 months (4.71 ± 0.56 to 3.57 ± 0.67 kg and 6.50 ± 0.34 to 3.66 ± 0.72 kg/m², respectively) with a concurrent 45% decrease in leptin. The increase in lean mass was higher than the increase in weight (5.27 versus 3.65 kg, respectively) due to fat loss.

Logistic regression assessed the odds of any breastfeeding initiation. Cox proportional hazards assessed duration of any breastfeeding. <b><i>Results:</i></b> Sample included 2,382,290 women (6.1% PCOS).

This outcome remained significant after controlling for body mass index (BMI; OR_adj: 1.3 [1.1, 1.6]; <i>p</i> = 0.005) but not after controlling for education and prior live births (OR_adj: 1.10 [0.89, 1.37]; <i>p</i> = 0.37).

In this national survey measuring any breastfeeding, PCOS did not decrease breastfeeding initiation or duration, despite confirming the association between overweight/obesity and decreased breastfeeding. However, because the data did not distinguish between exclusive breastfeeding and supplementation, we cannot rule out the possibility that PCOS affects breastfeeding exclusivity or necessitates supplementation. This limitation suggests that important trends could be obscured, and therefore, our findings should be interpreted with caution regarding breastfeeding exclusivity. Interventions aimed at increasing breastfeeding should target populations that would benefit the most; our data support that PCOS-specific targeting is not needed.
