Fit & Strong! Plus Trial Outcomes for Obese Older Adults with Osteoarthritis.

ABSTRACT:

Background and objectives

We compared the effectiveness of standard Fit & Strong! (F&S!; targets physical activity [PA]) to Fit & Strong! Plus (F&S! Plus; targets PA and dietary weight loss) on weight, diet quality, and PA outcomes.

Research design and methods

We randomly assigned 413 overweight older adults with OA to the F&S! or F&S! Plus programs and assessed outcomes at 2 and 6 months.

Results

The F&S! Plus group lost -2.0 ± 0.2 kg (mean ± SE, 2% of starting weight) at 2 months that was maintained at 6 months. Two- and 6-month BMI and waist circumference improved significantly in the F&S! Plus group (p < .001). Diet quality at 2 months showed greater improvement in the F&S! Plus group: 4.6 ± 0.7 versus 2.0 ± 0.7, p = .006, with no significant difference between groups at 6 months. The F&S! Plus group differentially improved on PA engagement at 2 months and at 2 and 6 months in joint pain (6-month mean ± SE: -1.5 ± 0.3 vs -0.6 ± 0.3, p = .02), function (-4.7 ± 0.9 vs -1.5 ± 0.9, p = .01), and 6-min walk test (29.5 ± 5.1 m vs 14.1 ± 5.2 m, p = .04).

Discussion and implications

Adding a dietary weight loss component to F&S! achieved weight and waist circumference benefits that were maintained at 6 months. Importantly, the weight loss was accompanied by clinically meaningful improvements in OA symptoms and mobility. Future work should investigate minimum thresholds for weight reduction that improve long-term function in this population.

Project description:BACKGROUND:Older adults have high rates of obesity and are prone to chronic health conditions. These conditions are in part due to high rates of sedentary time (ST). As such, reducing ST could be an innovative strategy for improving health outcomes among obese older adults. To test this theory, we developed a novel, technology-enhanced intervention to reduce sitting time (I-STAND) and pilot tested it to assess the feasibility, acceptability, and preliminary effects of the intervention on ST and biometric outcomes. OBJECTIVE:The current paper aims to describe the rationale, design, and methods of the I-STAND sitting reduction pilot trial. METHODS:Older adults with obesity (n=60) were recruited from a large health care system and randomized to receive I-STAND or a healthy living intervention. I-STAND combined personal coaching with a technology-enhanced intervention (Jawbone UP band) to cue breaks from sitting. Participants completed self-report and biometric assessments at baseline and 3 months. Additional qualitative results were collected from a subset of I-STAND participants (n=22) to further inform the feasibility and acceptability of the interventions. The primary outcome was total hours of daily sitting time measured by the activPAL device. Secondary outcomes included sit-to-stand transitions, bouts of sitting longer than 30 minutes, physical function, blood pressure, fasting glucose, cholesterol, and depressive symptoms. RESULTS:Study enrollment has ended and data processing is underway. CONCLUSIONS:Data from randomized trials on sitting reduction are needed to inform novel approaches to health promotion among older adults with obesity. Our trial will help fill this gap. The methods used in our study can guide future research on using technology-based devices to assess or prompt sedentary behavior reduction, or those interested in behavioral interventions targeting obese older adults with novel approaches.
