Breastfeeding intention and duration are negatively associated with maternal weight status and prenatal mental health. Potential factors include disparities in care for women with higher BMI and the impact of depression symptoms on the relationship between weight status and breastfeeding intention.
Background: Breastfeeding is widely recognized as the optimal feeding method for infants. However, breastfeeding goals are often unmet, especially in mothers with excessive weight. Potential factors associated with unmet goals could be disparities in care for women with higher body mass index (BMI) or mental health symptomology.Methods: Women enrolled in a longitudinal study were stratified by BMI into three groups: mothers with normal weight (18.5-24.9 kg/m2, n = 101), with overweight (25-29.9 kg/m2, n = 78), and with obesity (OB; 30-35 kg/m2, n = 48). Breastfeeding intention and standardized mental health questionnaires were administered at gestational weeks 12 and 36. The prevalence of initiation and duration of breastfeeding were determined based on self-reported breastfeeding start and end dates. Wilcoxon tests, pairwise proportion test, Cox proportional hazards regression, and linear regression were used.Results: Higher maternal weight status (OB) was significantly associated with lower breastfeeding intention and duration. As expected, higher breastfeeding intention scores were associated with significantly longer breastfeeding duration. Higher scores on the Beck Depression Inventory (BDI), associated with a greater number of depression symptoms, mediated the negative impact of weight status on breastfeeding intention.Conclusions: breastfeeding outcomes are negatively associated with maternal weight status and prenatal mental health with the relationship between the two being interconnected, despite subclinical scores on the BDI. Further research is needed to explore the role of mental health on breastfeeding outcomes. From these findings, targeted prenatal interventions for women with excessive weight and depressive symptoms would likely promote and improve breastfeeding outcomes.ClinicalTrials.gov: www.clinicaltrials.gov, ID #NCT01131117.
