Description
No studies have evaluated the impact of tracking resting energy expenditure (REE) and modifiable health behaviors on gestational weight gain (GWG). In this controlled trial, pregnant women aged >18 years (X=29.8±4.9 years) with a gestational age (GA) <17 weeks were randomized to Breezing™ (N=16) or control (N=12) for 13 weeks. The Breezing™ group used a real-time metabolism tracker to obtain REE. Anthropometrics, diet, and sleep data were collected every 2 weeks. Rate of GWG was calculated as weight gain divided by total duration. Early (GA weeks 14-21), late (GA weeks 21-28), and overall (GA week 14-28) changes in macronutrients, sleep, and GWG were calculated. Mediation models were constructed using SPSS PROCESS macro using a bootstrap estimation approach with 10,000 samples. The majority of women were non-Hispanic Caucasian (78.6%). A total of 35.7% (n=10), 35.7% (n=10), and 28.6% (n=8) were normal weight, overweight, and obese, respectively, with 83.3% (n=10) and 87.5% (n=14) of the Control and Breezing™ groups gaining above IOM GWG recommendations. At baseline, macronutrient consumption did not differ. Overall (Breezing™ vs. Control; M diff=-349.08±150.77, 95% CI: -660.26 to -37.90, p=0.029) and late (M diff=-379.90±143.89, 95% CI:-676.87 to -82.93, p=0.014) changes in energy consumption significantly differed between the groups. Overall (M diff=-22.45±11.03, 95% CI: -45.20 to 0.31, p=0.053), late (M diff=-23.16±11.23, 95% CI: -46.33 to 0.01, p=0.05), and early (M diff=20.3±10.19, 95% CI: -0.74 to 41.34, p=0.058) changes in protein differed by group. Nocturnal total sleep time differed by study group (Breezing vs. Control; M diff=-32.75, 95% CI: -68.34 to 2.84, p=0.069). There was a 11.5% increase in total REE throughout the study. Early changes in REE (72±211 kcals) were relatively small while late changes (128±294 kcals) nearly doubled. Interestingly, early changes in REE demonstrated a moderate, positive correlation with rates of GWG later in pregnancy (r=0.528, p=0.052), suggesting that REE assessment early in pregnancy may help predict changes in GWG. Changes in macronutrients did not mediate the relationship between the intervention and GWG, nor did sleep mediate relationships between dietary intake and GWG. Future research evaluating REE and dietary composition throughout pregnancy may provide insight for appropriate GWG recommendations.

Description
Exclusivity and duration of breastfeeding and the provision of human milk in the United States is suboptimal. In the absence of adequate banked donor human milk for distribution to all infants in need, many families choose to engage in the practice of Private Arrangement Milk Sharing (PAMS), partially facilitated through social media, to procure human milk for their infants. Evidence regarding the participant and infant characteristics and risk abatement practices is incomplete. This dissertation describes and explores the characteristics of recipient participants and infants, family constellation, donor screening practices, and related risk abatement strategies. Data was collected via on-line survey as a sub-group of a larger data set including donor participants and international participants. Binary logistic regression modeling of factors that contribute to consistent screening and risk abatement practices and important antecedents to engaging in PAMS was conducted. Results are contextualized within a tailored socioecological framework of factors affecting infant feeding practices. Tailoring was accomplished via qualitative descriptive analysis of participant responses applied to an existing breastfeeding framework. Participants in this sample were predominantly white, married, with a mean age of 32.9 years, with at least some college education and above median income. Risk abatement and screening practices were influenced by support of a healthcare provider during decision-making, college education, infant age and health status, having lactation support, birth type and birth attendant, and the duration and sources sought for learning about milk sharing.

Description
Scientific evidence strongly indicates that there are significant health benefits of breastfeeding. Lower breastfeeding initiation, duration, and exclusivity rates are found in vulnerable populations particularly among women of low socioeconomic status, and racial minorities such as immigrant, racial, and minority cultural groups. Breastfeeding disparities can contribute to negative health outcomes for the mothers, and their infants, and families.
Muslim Arab immigrants are a fast-growing, under-studied, and underserved minority population in the United States. Little is known about breastfeeding practices and challenges facing this vulnerable population. Immigrant Muslim Arab mothers encounter breastfeeding challenges related to religion, language, different cultural beliefs, levels of acculturation, difficulties understanding health care information, and navigating the health care system.
A cross-sectional descriptive study was used to describe infant feeding practices, and identify contributors and barriers to adequate breastfeeding using the social ecological model of health promotion. A convenience sample of 116 immigrant Muslim Arab women with at least one child, 5 years or younger was recruited from a large metropolitan area in the Southwestern United States. The results indicated that immigrant Muslim Arab mothers demonstrate high breastfeeding initiation rates (99.2%), and lengthy breastfeeding duration (M=11.86), but low rates of exclusive breastfeeding at 6 months (21.6%). Facilitators to breastfeeding within the sample were high intentions to breastfeed, positive breastfeeding knowledge and beliefs related to the benefits of breastfeeding, religious teachings promoting breastfeeding, and encouragement to breastfeed from the mothers’ social support system. Several barriers to successful breastfeeding were related to lacking the specific knowledge of the benefits of breastfeeding, and discomfort with breastfeeding in public, and in front of strangers. High income and religious teachings encouraging breastfeeding were significantly associated with exclusive breastfeeding at six months. Greater maternal age and comfort with breastfeeding in public were associated with longer breastfeeding durations.
The socio-cultural context for support of breastfeeding is an important consideration by healthcare providers caring for Muslim Arab women. An ecological perspective needs to be applied to interventions targeting breastfeeding promotion to facilitate effectiveness in this population. Culturally tailored intervention to the specific breastfeeding concerns and needs of Muslim immigrant women could promote optimal breastfeeding in this population.
