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 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.

Abstract Objectives Obesity is a major health concern in mid and later life; ≥40% of those ≥60 years are obese. However, the optimal approach for obesity reduction during the latter half of life has not been identified. Consuming balanced, liberal amounts of high quality protein at each meal is recommended for older adults and could help preserve lean mass and physical function. This study examined the feasibility and efficacy of this approach in the context of a weight reduction intervention for obese middle-aged and older adults. Methods This analysis combines findings on calorie and protein intakes of obese participants (mean BMI = 37.4 kg/m2; 88.7% female) aged ≥ 45 yrs (mean = 64.8 yrs) from two RCTs with similar protocols. Participants were randomized to hypo-caloric diets with either RDA level protein (0.8 g/kg bw; C-WL) or higher protein (1.2 g/kg bw; HP-WL) for 6 months. The HP-WL group was counseled to consume 30 g high quality protein/meal and provided lean beef or pork for 2 of 3 meals daily. Both groups had weekly group counseling and weigh-ins. Diet records (3-day) collected at 0, 3 and 6 months were analyzed (Food Processor; ESHA Research) for daily intakes of kcals and macronutrients. Results Both C-WL (n = 30) and HP-WL (n = 59) reduced their kcal intake and successfully reduced their body mass. At 6 months, weight loss was 5.8% and 7.0% for C-WL and HP-WL, respectively. Diet record analysis confirmed HP-WL participants achieved intakes of 30 g protein/meal. At 3 and 6 months respectively, mean ± SD protein intakes were 30.1 ± 9.9 g and 29.7 ± 12 g for breakfast; 37.5 ± 8.2 g and 35.6 ± 9.3 g for lunch; and 40.7 ± 13.7 g and 39.2 ± 8.1 g for dinner; daily protein intake was 1.2 ± 0.3 g/kg bw. In contrast, the C-WL protein intakes remained unchanged (0.8 g/kg bw). Conclusions These findings confirm the feasibility of a balanced, higher protein weight loss diet for obese middle-aged and older adults. HP-WL participants achieved notable weight reduction while also meeting meal protein goals. This practical dietary approach may offer superior long-term outcomes for physical function in this high-risk population; thus, further study of these potential benefits is warranted.

Abstract Age-related increases in chronic inflammation lead to reduced physical function via damage to muscle and joints and contribute to osteoarthritis (OA) risk. Obesity in older adults with OA further exacerbates inflammatory damage. Whether obesity reduction can lessen inflammation and improve OA is unknown; however, novel biomarkers may provide an answer. We completed a 6-mo. weight loss intervention (-500 kcal/day), studying blood biomarkers of inflammation and cartilage damage along with physical function in obese older adults with (OA+; n=39) and without an OA diagnosis (OA-; n=20). Participants were aged &gt; 60 yrs (mean = 70.2±6.0) and obese (BMI =34.6±4.7 kg/m2). At endpoint, weight loss was -6.3±4.0% and -5.8±4.1% in OA+ and OA-, respectively, with no group difference. Change scores for function for OA+ and OA- were: Short Physical Performance Battery score (+1.7±1.3 and +2.1±1.5), 8 ft up and go (-0.7±1.0 and -0.9±1.12 sec) and 6 min walk (+31.4±105.1 and +39.5±57.4 meters). All improved from baseline (p&lt;0.05), with no group difference. Concerning blood biomarkers, there was a decrease (p&lt;0.05) in cartilage oligomeric matrix protein (COMP: OA biomarker), indicating a potential benefit for OA. Change in COMP also differed between groups; OA- had a greater (p&lt;0.05) reduction than OA+. Pooled results showed improved adiponectin (p&lt;0.05), with no group difference. There were no changes for CRP, CTX-1, IL-6 and TNF-α. Our novel findings link early intervention with better reduction of OA risk and inflammation in obese older adults and also show important benefits for improved physical function regardless of OA status.
