Abstract The purpose of this study is to explore whether the effect of intentional weight loss on physical function in older adults varies by sex/gender. Individual level data from 1369 older, (67.7±5.4 years), obese (BMI: 33.9±4.4 kg/m2), adults (30% male, 21% African American) who participated in eight randomized controlled trials of weight loss were pooled. All studies were 5-6 months in duration and collected baseline demographic and pre/post gait speed (n=1296), short physical performance battery (SPPB; n=866), and grip strength (n=401) data. Treatment effects were generated by weight loss assignment [weight loss (WL; n=764) versus non-weight loss (NWL; n=605)], as well as categorical amount of weight change (high loss: >-7%, moderate loss: -7 to -3%, and weight gain/stability: <-3%). Analyses were adjusted for age, race/ethnicity, study, education, baseline BMI, and baseline value of the outcome measure of interest. Sex/gender stratified results were presented if the interaction term was p≤0.10. A sex/gender*weight loss assignment interaction was observed for SPPB (p=0.07), with women experiencing greater weight loss-associated improvement in SPPB score (WL: 0.42±0.08 versus NWL: 0.10±0.09; p=0.02) compared to men (WL: 0.30±0.11 versus NWL: 0.30±0.13). A sex/gender*weight loss amount interaction was observed for grip strength (p=0.05), with no difference observed across categories in women; however, greatest grip strength improvement was seen in men experiencing moderate weight loss compared to high loss and weight gain/stability categories. Weight loss-associated improvement in SPPB score is greater in women than men; grip strength gains in men are greatest among those achieving moderate weight loss.

Race/ethnicity stratified results were presented if the interaction term was p≤0.10. A race/ethnicity*weight loss assignment interaction was observed for gait speed (p=0.07), with African Americans experiencing greater weight loss-associated improvement (WL: 0.07±0.01 m/s versus NWL: 0.02±0.01 m/s; p=0.03) compared to Whites (WL: 0.08±0.01 m/s versus NWL: 0.07±0.01 m/s). A race/ethnicity*weight loss amount interaction was also observed for gait speed (p<0.01), with greater weight loss associated with greater improvement in both African Americans and Whites; although, gains were most apparent in African Americans experiencing high loss (0.12±0.02 m/s) compared to gain/stability (0.01±0.01 m/s). The beneficial effects of weight loss on gait speed appear greater in African Americans and are augmented with greater weight loss.

Abstract Objectives Obesity affects a growing number of older adults, contributing to poor physical and mental health outcomes; meanwhile, treatments to reduce obesity in older adults are complicated by a relatively limited treatment window and potential loss of lean mass. Furthermore, obesity's prevalence is unevenly distributed and highest among black and Hispanic older adults, thus contributing to ongoing health disparities. Recent research from our laboratory shows that higher protein intake (≥30 g/meal) enhances functional improvement during intentional weight loss but it is not yet known whether these effects are consistent across race. Methods In an ancillary pilot study, change in body weight, physical function (Short Physical Performance Battery), and cognitive function (Trail Making Test, TMT; Symbol Digit Modalities, SMD) was assessed among obese black and white older adults with mild to moderate functional impairment (n = 10) following 3 months of weight loss intervention at one of two protein intake levels (RDA 0.8 vs 1.2 g/kg/d and (≥30 g/meal) and moderate exercise. Results Significant weight loss (P = 0.009) and improvement in physical function (SPPB; P = 0.008) were observed at 3 months. While protein effects were not observed in this subset, trends toward race*time interactions showing greater weight loss among white participants (P = 0.062) and greater function improvement among black participants (P = 0.067) were observed. Additionally, cognitive assessment revealed a race*time interaction on TMT performance (TrailsB-A; P = 0.012), which correlated with changes in body weight and physical function. Conclusions These preliminary findings suggest that obesity reduction interventions benefited older adults across multiple health domains and underscore the need for further research to characterize potentially divergent benefits of intentional weight loss within these populations.

Abstract Background Older adults with obesity residing in rural areas have reduced access to weight management programs. We determined the feasibility, acceptability and preliminary outcomes of an integrated technology-based health promotion intervention in rural-living, older adults using remote monitoring and synchronous video-based technology. Methods A 6-month, non-randomized, non-blinded, single-arm study was conducted from October 2018 to May 2020 at a community-based aging center of adults aged ≥65 years with a body mass index (BMI) ≥30 kg/m2. Weekly dietitian visits focusing on behavior therapy and caloric restriction and twice-weekly physical therapist-led group strength, flexibility and balance training classes were delivered using video-conferencing to participants in their homes. Participants used a Fitbit Alta HR for remote monitoring with data feedback provided by the interventionists. An aerobic activity prescription was provided and monitored. Results Mean age was 72.9±3.9 years (82% female). Baseline anthropometric measures of weight, BMI, and waist circumference were 97.8±16.3 kg, 36.5±5.2 kg/m2, and 115.5±13.0 cm, respectively. A total of 142 participants were screened (n=27 ineligible), and 53 consented. There were nine dropouts (17%). Overall satisfaction with the trial (4.7+ 0.6, scale: 1 (low) to 5 (high)) and with Fitbit (4.2+ 0.9) were high. Fitbit was worn an average of 81.7±19.3% of intervention days. In completers, mean weight loss was 4.6±3.5 kg or 4.7±3.5% (p< 0.001). Physical function measures of 30-s sit-to-stand repetitions increased from 13.5±5.7 to 16.7±5.9 (p< 0.001), 6-min walk improved by 42.0±77.3 m (p=0.005) but no differences were observed in gait speed or grip strength. Subjective measures of late-life function improved (3.4±4.7 points, p< 0.001). Conclusions A technology-based obesity intervention is feasible and acceptable to older adults with obesity and may lead to weight loss and improved physical function.

Abstract Background Observational research has identified several mortality biomarkers; however, their responsiveness to change is unknown. We tested whether the Healthy Aging Index (HAI) and other mortality biomarkers were responsive to intentional weight loss (WL), which is associated with lower mortality risk in recent meta-analyses. Methods Older adults (70.3 ± 3.7 years) with obesity were randomized into a 6-month WL (n = 47) or weight stability (WS: ±5% baseline weight; n = 48) program. Baseline and 6-month HAI score (0–10) was calculated from component sum (each 0–2: systolic blood pressure, forced vital capacity [FVC], creatinine, fasting blood glucose [FBG], Montreal Cognitive Assessment), and gait speed, grip strength, Digit Symbol Substitution Test, FEV1, Interleukin-6, C-Reactive Protein, and Cystatin-C were assessed at baseline and 6 months. Results Mean baseline HAI was 3.2 ± 1.6. By 6 months, WL participants lost 8.87 (95% CI: −10.40, −7.34) kg, whereas WS participants remained weight stable. WL group reduced HAI score (WL: −0.75 [95% CI: −1.11, −0.39] vs WS: −0.22 [95% CI: −0.60, 0.15]; p = .04), and components changing the most were FBG (WL: −3.89 [95% CI: −7.78, 0.00] mg/dL vs WS: 1.45 [95% CI: −2.61, 5.50] mg/dL; p = .047) and FVC (WL: 0.11 [95% CI: −0.01, 0.23] L vs WS: −0.05 [95% CI: −0.17, 0.08] L; p = .06). Among other biomarkers, only Cystatin-C significantly changed (WL: −2.53 [95% CI: −4.38, −0.68] ng/mL vs WS: 0.07 [95% CI: −1.85, 1.98] ng/mL; p = .04). Combining treatment groups, 1 kg WL was associated with a 0.07 (95% CI: 0.03, 0.12) HAI reduction (p &lt; .01). Conclusion Intentional WL via caloric restriction reduced HAI score by 0.53 points, largely attributable to metabolic and pulmonary improvements.

Abstract Objectives Obesity imposes risk to cardiometabolic health; however, intentional weight loss in obese older adults remains controversial. Using data from the CROSSROADS Study (clinicaltrials.gov #NCT00955903), this ancillary study investigated effects of exercise with and without intentional weight loss on changes in cardiometabolic risk assessed by four risk-scoring tools. Methods Participants (n = 134, 39% male, 23% African American, 70.2 ± 4.7 y) were randomized to exercise (n = 48), exercise + nutrient-dense weight maintenance diet (n = 44), or exercise + nutrient-dense caloric restriction of 500 kcals/day (n = 42). The following risk scores were calculated using baseline and 12-month data: Framingham risk assessment, Cardiometabolic Disease Staging (CMDS), metabolic syndrome classification by the International Diabetes Federation (IDF), and metabolic syndrome classification by the National Cholesterol Education Program's Adult Treatment Panel (ATP III). Generalized Estimating Equations were employed to determine differences between groups with ethnicity, sex, and age as covariates. Results Group-time interaction was not significant in application of IDF or ATPIII. Group-time interaction was significant for Framingham and CMDS (P = 0.005 and 0.041, respectively). Upon post-hoc analysis, significant within-group improvements in Framingham scores were observed for exercise + weight maintenance (P &lt; 0.001, r = −1.682) and exercise + weight loss (P = 0.020, r = −0.881). In analysis of between-group differences in Framingham scores, a significant decrease was observed in the exercise + weight maintenance group (P = 0.001, r = −1.723) compared to the exercise group. For CMDS, the exercise + weight loss group had significant within-group improvements (P = 0.023, r = - 0.102). For between-group differences in CMDS, the exercise + weight loss group showed significant risk score reduction (P = 0.012, r = −0.142) compared to the exercise group. Conclusions Risk assessment by Framingham and CMDS showed greater sensitivity to change in cardiometabolic risk factors. Results suggest obese older adults can lower cardiometabolic risk by engaging in exercise + weight maintenance or exercise + weight loss by moderate caloric restriction.

Abstract Background and aims There are associations between pain, comorbidity and risk of falling, and falling increases the risk of mortality in older persons, but few studies have investigated the development of pain as a result of impaired physical function. The aim of this study was to examine possible associations between weak physical performance and the development of musculoskeletal pain that interferes with normal life in a sample of older adults. The sample derived from a national, longitudinal multicenter study; the Swedish National Study on Ageing and Care; SNAC-B. Methods The participants (n = 490) were between 60 and 78 years at the baseline examinations. Three variables were chosen for the exposure physical function, from the baseline examinations; One Leg Stand, Grip strength and Sit-to-Stand. The outcome musculoskeletal pain that interferes with normal life was measured using EQ5D and SF-12 6 years later, and logistic regression was used to investigate possible associations between the exposures and the outcome. Results Maximum grip strength (Grippit) was inversely associated with musculoskeletal pain that interferes with normal life (OR 2.31; 95% CI 1.15–4.61), and One-Leg Stand and Sit-to-Stand were not associated with the development of pain (OR 1.30; 95% CI 0.64–2.64) and (OR 0.91; 95% CI 0.45–1.86), respectively. Conclusions Weak grip strength was inversely associated with the development of musculoskeletal pain that interferes with normal life in older adults. Implications Impaired proprioceptive function, strength and mobility in elderly with pain have been found in earlier research. Since pain increases the risk of falling, it is important to investigate if it may develop as a function of an impaired physical function. The results of the present study could be of importance for future prevention programs aiming to protect elderly from falling.

Abstract Background Group lifestyle sessions with phone maintenance could improve weight, health, and function in vulnerable older adults. Methods Community-dwelling adults (N = 322) with body mass index (BMI, kg/m2) ≥27 and additional risk factors received 12 one-hour in-person behavioral weight management group sessions then were randomized to 8 half-hour telephone sessions (n = 162) or newsletter control (n = 160) from 4 to 12 months with no treatment contact thereafter. Primary outcome was 0- to 12-month weight change. Cardiometabolic, short physical performance battery (SPPB), and self-reported activity changes were assessed at 12 and 24 months. Results At baseline, the mean (SD) age was 71.2 (4.3) and BMI was 33.8 (5.1). Participants were 77% women, 13% Black, 85% retired, averaging 4 medical conditions, and taking blood pressure (67.4%) and lipid-lowering (51.6%) medications. At 12 months, a greater proportion of the phone group (66.0%) achieved ≥5% weight loss compared with newsletter control (53.2%; p = .02). Mean (95% CI) weight loss was greater for phone (−6.6 kg [−7.5, −5.8]) than newsletter (−5.1 kg [−7.2, −3.0]); p = .01. Modest lipid, glucose, and blood pressure improvements were found, but did not differ significantly between groups. Small SPPB and activity improvements were maintained at 12 and 24 months in both groups. Conclusions Brief phone contacts compared to newsletters enhanced weight loss maintenance among older high-risk adults at 1 year, but not cardiometabolic outcomes. Modest functional improvements were observed in both. Lower-intensity maintenance contacts (phone or newsletter) for weight, health, and physical function in older adults warrant further study.
