Maternal and Infant Feeding Status Related to Infant Temperament, Postpartum Depression, and Weight

Description

This longitudinal research study addresses the correlations between infant feeding status in relation to infant temperament, maternal postpartum depression, and weight changes over time in a lower income, diverse population sample. The majority of participants were enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Mesa, Arizona. Each participant was recruited in their third trimester and followed for the infants' first six months of life. A series of four home visits were made in which demographic surveys, temperament questionnaires, postpartum depression scales, weight changes over time, fecal, vaginal, saliva, and breast milk samples were taken. Due to the extensive process of extracting and sequencing of the microbiome samples, data has yet to be collected from the fecal, vaginal, saliva, and breast milk samples and were not included in this study. Correlational and descriptive statistics were run on the qualitative data including various demographic questions, total temperament, depression, and healthy eating index scores. It was found that lower socioeconomic factors contributed to more difficult infant temperaments, mothers who breastfed had higher post-delivery postpartum depression scores, and mothers with healthier eating indexes formula or mixed fed their infants. The findings from this data will be compared to the incoming microbiome data to examine the role of the microbiome of mothers and infants and its effects on infant temperament, postpartum depression, and weight changes over time.

Associations between Early Postpartum Maternal Sleep and Distress on Infant Temperament

Description

This study assessed whether elevated levels of maternal stress and anxiety and disturbed maternal sleep would be associated with greater negative infant temperament. The study was part of a larger longitudinal observational study investigating whether sleep-wake and gut microbiome development are associated with infant rapid weight gain in their first year. The present study focused on data from 43 mother-infant dyads collected at six months postpartum using the Depression and Anxiety Stress Scales (DASS), maternal wrist actigraphy sleep data (for five days and nights), maternal sleep diaries, the Pittsburgh Sleep Quality Index (PSQI), and the Infant Behavior Questionnaire-Revised (IBQ-R) very short form. While controlling for maternal age and anxiety, regression analyses revealed that lower actigraphy-assessed maternal sleep efficiency predicted greater infant negative affect, and greater actigraphy-assessed maternal total sleep time predicted lower infant surgency at six months. Maternal stress and anxiety were not significantly associated with infant temperament. This secondary study adds value to the literature with the inclusion of objective measurement of maternal sleep and consideration of other dimensions of maternal psychological distress that were previously highly examined in the scientific literature.
