MEASURED AND PREDICTED RESTING ENERGY EXPENDITURE IN OVERWEIGHT BLACK AND WHITE YOUNG ADULT WOMEN

Daishan Johnson, Ronald Evans, FACSM, Autumn Lanoye, Jessica LaRose. Virginia Commonwealth University, Richmond, VA. BACKGROUND: Resting energy expenditure (REE) is the major determinant of total energy expenditure and is reported to be reduced in Black compared to White individuals. This study aims to assess and evaluate the relationship between REE and body composition (BC) measures in overweight Black and White young adult women and explore the accuracy of common REE prediction equations. METHODS: Weight (WT), height (HT), measured REE (REEM; Fitmate GS, Cosmed USA Inc.), and BC (BC-418, Tanita Corp.) were assessed in Black (n=79) and White (n=96) non-hispanic women (age=22.2 ± 2.1; BMI≥25 kg/m2) enrolling in a behavioral weight loss (BWL) program. In addition to REEM, the accuracy of 4 common REE prediction (REEP) equations was evaluated: Harris-Benedict, Mifflin-St. Jeur, Owen, and World Health Organization. RESULTS: Black women had significantly (p\u3c0.05) higher WT, BMI, and % fat and significant correlations were observed between REEM and all BC variables in both groups. No significant differences were observed in unadjusted REEM (1534±240 vs. 1525±274 kcals/day; p=0.82); however, REEM adjusted for WT was significantly lower in Black women (1492±201 vs. 1561±201 kcals/day; p=0.028). The Owen equation demonstrated the highest accuracy in both groups with ~63% of REEP values within ±10% of REEM. CONCLUSIONS: The observed difference in weight adjusted REEM between the groups has implications for caloric intake and physical activity goal setting in BWL. Further research is needed to determine if the observed difference in REEM impacts weight loss outcomes and weight loss maintenance. This work was supported by NIH R01DK103668 to JGL

A scalable, virtual weight management program tailored for adults with type 2 diabetes: effects on glycemic control

Abstract Background The objective was to test the efficacy of a scalable, virtually delivered, diabetes-tailored weight management program on glycemic control in adults with type 2 diabetes (T2D). Methods This was a single arm, three-site clinical trial. Participants had baseline HbA1c between 7–11% and BMI between 27–50 kg/m2. Primary outcome was change in HbA1c at 24 weeks. Secondary outcomes were changes in body weight, waist circumference, the Diabetes Distress Scale (DDS), quality of life (IWQOL-L), and hunger (VAS). Generalized linear effects models were used for statistical analysis. Results Participants (n = 136) were 56.8 ± 0.8 y (Mean ± SEM), 36.9 ± 0.5 kg/m2, 80.2% female, 62.2% non-Hispanic white. Baseline HbA1c, weight, and total DDS score were 8.0 ± 0.09%, 101.10 ± 1.47 kg, and 2.35 ± 0.08, respectively. At week 24, HbA1c, body weight, and total DDS decreased by 0.75 ± 0.11%, 5.74 ± 0.50%, 0.33 ± 0.10 units, respectively (all p < 0.001). Also, at week 24, quality of life increased by 9.0 ± 1.2 units and hunger decreased by 14.3 ± 2.4 units, (both p < 0.0001). Conclusions The scalable, virtually delivered T2D-tailored weight management program had favorable and clinically meaningful effects on glycemic control, body weight, and psychosocial outcomes

Health-Related Quality of Life 5 Years After Roux-en-Y Gastric Bypass in Young (18-25 Years) Versus Older (≥ 26 Years) Adults : a Scandinavian Obesity Surgery Registry Study.

BACKGROUND: To compare changes in health-related quality of life (HRQoL) in young (18-25 years) versus older (≥ 26 years) adults up to 5 years after Roux-en-Y gastric bypass (RYGB). METHODS: Data on Short Form-36 (SF-36) and obesity-related problems scale (OP) at baseline and 1, 2, and 5 years after RYGB were extracted from the Scandinavian Obesity Surgery Registry. Within-group changes and the effect of age group on 5-year changes in SF-36 and OP were analyzed. Effects sizes (ESs) were calculated. RESULTS: A total of 2542 young and 12,425 older adults were included at baseline, and 138 young (20.7% of those eligible) and 1021 older (31.8%) adults were followed-up 5 years post-RYGB. At this time, average to large improvements (ES ≥ 0.5) were observed in physical functioning, physical component score and OP in young adults, and in physical functioning, role physical, general health, physical component score, and OP in older adults (all, p ≤ 0.001). Both age groups displayed negligible to weak (ES &lt; 0.5) or no improvements in mental HRQoL (all, p &lt; 0.55). Older adults displayed greater 5-year improvements than their young counterparts in role physical, general health, vitality, social functioning, physical component score, and obesity-related problems scale (all, p &lt; 0.05). CONCLUSIONS: Both young and older adults displayed improvements in OP and physical HRQoL 5 years post-RYGB compared to baseline, while mental HRQoL did not improve to the same extent. Greater HRQoL-improvements could be expected in older patients why future research on HRQoL post-RYGB should stratify data on age groups
