People can improve mental health by increasing experiences of positive emotions. A study, published recently in the Journal of Women’s Health (Larchmt) determined the extent to which positive emotions during infant feeding are associated with maternal depression and anxiety during the first year postpartum. In all, 164 women from a longitudinal cohort of mother-infant dyads were followed from the third trimester to 12 months postpartum. Positive emotions during infant feeding were assessed at 2 months using the mean subscale score of the modified Differential Emotions Scale. Depression and anxiety symptoms were assessed using the Beck Depression Inventory-II and State Trait Anxiety Inventory-State subscale at 2, 6, and 12 months. Generalized linear mixed models helped estimate crude and multivariable associations. Among women with no clinical depression during pregnancy, higher positive emotions during infant feeding at 2 months correlated with significantly fewer depression symptoms at 2, 6, and 12 months and with decreased likelihood of clinically significant depression symptoms at 2 and 6 months. In contrast, women with clinical anxiety during pregnancy who experienced higher positive emotions had significantly fewer anxiety symptoms at 2, 6, and 12 months and lower odds of clinically significant anxiety at 2 and 6 months. Positive emotions during infant feeding were thus found to be associated with depression and anxiety outcomes during the first year postpartum and could serve as a modifiable protective factor for maternal mental health.
