Predictors of Improvement in Parental Stress After the First Three Months at Home with a Medically Fragile Infant.

OBJECTIVES: Little is known about the early stress experiences of parents of infants with serious life-limiting/life-threatening conditions during the initial months after discharge from hospital. The aim of the study was to measure change, and predictors of change, in parenting stress at the time of transition from hospital to home (T1) with a medically fragile infant, and after a 3-month period (T2). METHODS: Parents of infants identified as meeting ≥ 1 palliative care referral criterion were recruited in a Midwestern United States tertiary pediatric hospital (2012-2014) within 2 weeks of hospital discharge. A repeated measures design was used to assess change on a validated parenting stress inventory over the two timepoints (T1 and T2). Fifty-two parents (61 infants) participated at T1 and 44 (85%) at T2. RESULTS: On discharge (T1) stress was moderately high 3 months post discharge (T2) overall and domain-specific stress scores improved, except stress related to parent role functioning and participation in their child's medical care. Independent predictors of improvement in overall parenting stress scores (T2-T1) were being a younger parent and having experienced prior pregnancy-related loss. CONCLUSIONS FOR PRACTICE: The time of discharge from hospital to home is often stressful for parents of medically fragile infants. Improvements were found during the first 3 months at home, but improvement was minimal for stress related to role function and providing medical care. Past experience with pregnancy-related loss and being younger were associated with improvement in stress across theoretical domains. Screening for stress should be included as part of routine pre- and post-neonatal intensive care unit discharge psychosocial assessments of parents caring for infants with serious illness to ensure their unique support needs continue to be met over time.

What is already known about the topic? Stress in parents of sick infants is well-documented in the post-birth hospitalization period. Early management of parent stress after a child is born with a life-limiting/life-threatening condition is critical in promoting healthy infant attachment and development.What this study adds? Parents of medically fragile infants experience notable stress during the initial months at home. Pre-hospital discharge attention to medical and psychosocial characteristics of infants and parents may help health care teams anticipate post-discharge parenting challenges and facilitate personalized home support strategies aimed at minimizing parent stress and poor parent­child outcomes.

Association of Full Breastfeeding Duration with Postpartum Weight Retention in a Cohort of Predominantly Breastfeeding Women.

Full breastfeeding (FBF) is promoted as effective for losing pregnancy weight during the postpartum period. This study evaluated whether longer FBF is associated with lower maternal postpartum weight retention (PPWR) as compared to a shorter FBF duration. The MILK (Mothers and Infants Linked for Healthy Growth) study is an ongoing prospective cohort of 370 mother-infant dyads, all of whom fully breastfed their infants for at least 1 month. Breastfeeding status was subsequently self-reported by mothers at 3 and 6 months postpartum. Maternal PPWR was calculated as maternal weight measured at 1, 3, and 6 months postpartum minus maternal prepregnancy weight. Using linear mixed effects models, by 6 months postpartum, adjusted means ± standard errors for weight retention among mothers who fully breastfed for 1-3 (3.40 ± 1.16 kg), 3-6 (1.41 ± 0.69 kg), and ≥6 months (0.97 ± 0.32 kg) were estimated. Compared to mothers who reported FBF for 1-3 months, those who reported FBF for 3-6 months and ≥6 months both had lower PPWR over the period from 1 to 6 months postpartum (p = 0.04 and p < 0.01, respectively). However, PPWR from 3 to 6 months was not significantly different among those who reported FBF for 3-6 versus ≥6 months (p > 0.05). Interventions to promote FBF past 3 months may increase the likelihood of postpartum return to prepregnancy weight.

Higher Maternal Diet Quality during Pregnancy and Lactation Is Associated with Lower Infant Weight-For-Length, Body Fat Percent, and Fat Mass in Early Postnatal Life.

Maternal pregnancy nutrition influences fetal growth. Evidence is limited, however, on the relationship of maternal diet during pregnancy and lactation on infant postnatal growth and adiposity. Our purpose was to examine associations between maternal diet quality during pregnancy and lactation with offspring growth and body composition from birth to six months. Maternal diet quality was serially assessed in pregnancy and at one and three months postpartum, using the Healthy Eating Index⁻2015 in a cohort of 354 fully breastfeeding mother⁻infant dyads. Infant length-for-age (LAZ), weight-for-age (WAZ), and weight-for-length (WLZ) Z-scores were assessed at birth, one, three, and six months. Infant body fat percent (BF%), fat mass (FM), and fat-free mass (FFM) were measured at six months using dual-energy X-ray absorptiometry. Higher maternal diet quality from pregnancy through three months postpartum was associated with lower infant WLZ from birth to six months (p = 0.02) and BF% at six months (p ≤ 0.05). Higher maternal diet quality at one and three months postpartum was also associated with lower infant FM at six months (p < 0.01). In summary, maternal diet quality during pregnancy and lactation was inversely associated with infant relative weight and adiposity in early postnatal life. Additional research is needed to explore whether associations persist across the life course.
