Ibrahim, Department of Family and Consumer Sciences, North Carolina Agricultural & Technical State University, Greensboro, NC 27411Topic Area: Food Safety, Nutrition and HealthObesity in America has risen to epidemic levels. For women, childbearing itself might be a contributing factor. The American Academy of Pediatrics recommends exclusive breastfeeding for the first 6 months breastfeeding may help reduce long-term maternal weight retention from pregnancy and may decrease risk of childhood obesity. However, lactation is a time of rapid bone loss due to hyperprolactinemia, amenorrhea, and increased bone turnover. Lactation-induced bone loss is usually reversed with weaning; however, not all women recover from this bone loss which increases the risk of osteoporosis later in life. Weight bearing exercise and dairy intake (milk, yogurt, cheese) plus vitamin D supplementation may provide some protection from bone loss. Thus, the objective of this study is to promote long-term lifestyle changes that support healthy lifelong weight management for overweight- to- obese lactating women through a 12-week community based exercise intervention and daily yogurt consumption program. The study is currently in the initial stages of recruitment. Laboratory measurements occur at 8-weeks and 20-weeks postpartum After baseline measurements, participants will be randomized into either an intervention that will include community based exercise program and yogurt supplementation or a control. We predict no difference in infant growth (length, weight and head circumference), dietary intake, and hormone levels between the two groups. Intervention will increase fat-free mass and cardiovascular fitness; decrease fat mass, and less bone loss in lumbar spine and hip compared to control. Targeted exercise interventions and yogurt supplementation may help improve the weight-status and bone density postpartum, while promoting breastfeeding.This study is registered with ClinicalTrials.gov (# we are currently waiting on approval)*corresponding author: Dr. Heather L Colleran, PhD RDN [email protected] 336.285.3627Key words: Obesity, Postpartum, Lactation, Bone Density, Body composition, DairyPresenter: Graduate StudentPresentation Type: oral or poster -- no preference
