Obesity in America has risen to epidemic levels over the past 10 years; and for women, childbearing itself might be a contributing factor. Breastfeeding is recommended for the first six months and has been shown to help reduce long-term maternal weight retention from pregnancy. Conversely, lactation represents a period of increased bone loss, specifically of the lumbar spine and hip. Fermented dairy intake and weight-bearing exercise have been shown to provide bone protection in premenopausal women. Therefore, the objective of this study was to investigate the influence of yogurt supplementation and exercise on the attenuation of lactation-induced bone loss from 8-wks to 20-wks postpartum (PP). At 8-wks PP, women were randomized into either an intervention group that included dietary supplementation [IG, n=4, yogurt supplementation (≥ 3d/wk, 6oz each day) and exercise (3d/wk, 45min/d, ≥10,000 steps/d)] or a control group (CG, n=1, no dietary or exercise intervention) for 12-wks. Dual-energy x-ray absorptiometry (DXA) was used to measure body composition (weight, fat mass, lean body mass) and bone mineral density (BMD; total body, hip and lumbar spine). A submaximal treadmill test determined predicted maximal oxygen consumption (VO2 max). Three-day dietary records were collected using the Nutrition Data System for Research software, and significance was set at p<0.05. My results represent data for the first five participants to complete the study. Compliance for IG for 3-d/wk of yogurt consumption and exercise was 96.7% and 77%, respectively. IG lost 3.1% of their body weight compared to a 3.0% gain by CG, with p=0.4. There was no significant difference between the groups for weight change and body composition, with p>0.1. Although NS, IG lost less BMD compared to CG. The IG group increased their VO2 max 8%±7% versus CG -6%, p=0.16. There was no difference in dietary intake between groups over 12-weeks. These results suggest that yogurt supplementation and exercise may help improve the weight-status and bone density postpartum during lactation.
