Earlier Onset of Maternal Excess Adiposity Associated with Shorter Exclusive Breastfeeding Duration.

BACKGROUND: Exclusive breastfeeding for 6 months is recommended; however, women with obesity have lower exclusive breastfeeding rates than their normal weight peers. The impact of the timing of maternal excess adiposity onset is unknown. RESEARCH AIM: We examined whether the timing of onset of excess weight was related to exclusive breastfeeding duration. METHODS: Snowball sampling was used for the cross-sectional Breastfeeding Opinions, Outcomes, Behaviors, and Services online survey. The sample was 1,570 mothers who reported their breastfeeding and weight history. Exclusive breastfeeding duration (for first biological child only) was calculated in months and dichotomously (0=< 6 months exclusive breastfeeding; 1=⩾ 6 months exclusive breastfeeding). Participants self-reported their excess weight onset (0=before/during puberty or 1=after puberty). RESULTS: Analysis of covariance results indicated that earlier onset of excess weight was associated with shorter exclusive breastfeeding ( F (1, 1518) = 11.29, p<.001, η2=.01). Those with excess adiposity onset before or during puberty were 1.6 times more likely to experience exclusive breastfeeding failure (< 6 months exclusive breastfeeding) than those with onset after puberty ( OR = 1.57, ß = .46, Wald = 11.81, p = .001). CONCLUSION: Earlier onset of excess adiposity had an adverse influence on exclusive breastfeeding duration. Women with a history of excess adiposity before or during puberty who want to breastfeed may require additional intervention to promote their breastfeeding success.

Interpersonal suicide risk for American Indians: investigating thwarted belongingness and perceived burdensomeness.

American Indians (AIs) experience increased suicide rates compared with other groups in the United States. However, no past studies have examined AI suicide by way of a recent empirically supported theoretical model of suicide. The current study investigated whether AI suicidal ideation can be predicted by two components: thwarted belongingness and perceived burdensomeness, from the Interpersonal-Psychological Theory of Suicide (T. E. Joiner, 2005, Why people die by suicide. Cambridge, MA: Harvard University Press). One hundred seventy-one AIs representing 27 different tribes participated in an online survey. Hierarchical regression analyses showed that perceived burdensomeness significantly predicted suicidal ideation above and beyond demographic variables and depressive symptoms; however, thwarted belongingness did not. Additionally, the two-way interaction between thwarted belongingness and perceived burdensomeness significantly predicted suicidal ideation. These results provide initial support for continued research on the components of the Interpersonal-Psychological Theory of Suicide, an empirically supported theoretical model of suicide, to predict suicidal ideation among AI populations.
