Exploratory study of the women’s HPA axis function during perinatal period: the impact of breastfeeding cessation and depression
| Resumo: | Although the majority of the studies are consensual about an association between breastfeeding and the function of HPA axis, data regarding breastfeeding and HPA axis function over the time, taking account depression are limited. This study main aimed to analyze the impact of exclusive breastfeeding and breastfeeding cessation on several measures of COR. A sample of 30 primiparous women with an EPDS ≥ 9 at the third pregnancy trimester, reported Breastfeeding status, provided salivary samples of COR and completed questionnaires that measure depressive and anxiety symptoms, over the perinatal period. Results revealed exclusive breastfeeding cessation had an impact on the decrease of the overall secretion of COR during the day and both exclusive breastfeeding and breastfeeding cessation had an impact on the decrease of the CAR. The interaction effects between the impact of exclusive breastfeeding cessation and depressive symptoms on overall COR secretion during the day shows that women with more depressive symptoms at exclusive breastfeeding cessation have a greater decrease on the overall secretion of COR, after exclusive breastfeeding cessation. These results help to explain the functioning of the HPA axis underlying the benefits of breastfeeding and the risks of early breastfeeding cessation, especially in women with depressive symptoms. |
