Weight Loss through Lifestyle Intervention Improves Mobility in Older Adults.

ABSTRACT:

Background and objectives

The high prevalence of overweight or obesity in older adults is a public health concern because obesity affects health, including the risk of mobility disability.

Research design and methods

The Mobility and Vitality Lifestyle Program, delivered by community health workers (CHWs), enrolled 303 community-dwelling adults to assess the impact of a 32-session behavioral weight management intervention. Participants completed the program at 26 sites led by 22 CHWs. Participation was limited to people aged 60-75 who had a body mass index (BMI) of 27-45 kg/m2. The primary outcome was the performance on the Short Physical Performance Battery (SPPB) over 12 months.

Results

Participants were aged 67.7 (SD 4.1) and mostly female (87%); 22.7% were racial minorities. The mean (SD) BMI at baseline was 34.7 (4.7). Participants attended a median of 24 of 32 sessions; 240 (80.3%) completed the 9- or 13-month outcome assessment. Median weight loss in the sample was 5% of baseline body weight. SPPB total scores improved by +0.31 units (p < .006), gait speed by +0.04 m/s (p < .0001), and time to complete chair stands by -0.95 s (p < .0001). Weight loss of at least 5% was associated with a gain of +0.73 in SPPB scores. Increases in activity (by self-report or device) were not independently associated with SPPB outcomes but did reduce the effect of weight loss.

Discussion and implications

Promoting weight management in a community group setting may be an effective strategy for reducing the risk of disability in older adults.

Project description:Background and aimsObesity significantly impacts older adults. Intensive nutrition counseling can aid in weight reduction and improve diet quality, but data are sparse in this population. The objective of this intervention is to determine how intensive nutrition counseling affects diet quality and anthropometric measures during a multi-component weight loss intervention in rural older adults with obesity.MethodsA series of 12-week, single-arm feasibility pilots were conducted in fall 2017 and winter/spring 2018 in a community aging center in rural Northern New England. Adults were eligible if ≥ 65 years old with a Body Mass Index (BMI) ≥30 kg/m2. Exclusion criteria included dementia/cognitive impairment, uncontrolled psychiatric illness, weight-loss surgery, weight loss >5% in previous 6-months, life-threatening illness, palliative/hospice services, current participation in another weight-loss study/program, obesogenic medications, or presence of major chronic conditions. Participants received once-weekly nutrition counseling by a registered dietitian nutritionist (RDN), and twice-weekly exercise sessions by a physical therapist (PT). Primary outcomes were diet quality changes measured by total Rapid Eating and Activity Assessment for Patients-Short Version (REAP-S) and Automated Self-Administered 24-h dietary recall (ASA-24). Secondary outcome measures were changes in weight (kilograms) and waist circumference (centimeters). McNemar test was conducted for all paired categorical data while paired t-tests were conducted for all paired continuous data. All analyses were conducted in R; p-value<0.05 was significant.ResultsTotal n = 23. Mean age was 72.2 (5.8) years (73.9% female); mean BMI was 35.9 ± 5.0 kg/m2. At 12 weeks, diet quality significantly improved. REAP-S scores increased by 3.53 ± 3.13 points (p < 0.001). Kilocalories, grams fat, grams saturated fat, milligrams sodium, grams added sugar, and grams alcohol via ASA-24 significantly decreased (all p < 0.05). Significant reductions in weight (-5.22 ± 3.13 kg) and waist circumference (-6.88 ± 5.67 cm) were observed (both p < 0.001).ConclusionIntensive nutrition counseling significantly enhances diet quality and reduces weight and waist circumference in rural older adults with obesity.
