Takeaway

  • Adding an evidence-based weight loss program (ORBIT) to an evidence-based physical activity program (Fit & Strong! [F&S!]) targeting African Americans (AA; F&S! Plus) improved pain, function, and mobility in older (≥60 years) obese AA with osteoarthritis (OA).

Why this matters

  • Obesity increases risk for OA progression.
  • OA affects 54.4 million Americans, mostly older adults.

Study design

  • Randomized comparative effectiveness trial of F&S! Plus vs F&S! (n=413).
  • Diet quality was assessed by the Healthy Eating Index (HEI) 2010.
  • Pain and function were assessed by subscales of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
  • Mobility was assessed by the 6-minute walk test.
  • Funding: NIH; others.

Key results

  • 92% of participants were AA; 86% were women.
  • F&S! Plus (vs F&S!) decreased BMI and waist circumference at 2 and 6 months (all P<.001>
  • F&S! Plus (vs F&S!) improved diet quality at 2 months (P=.006).
  • F&S! Plus (vs F&S!) at 6 months had lower joint pain (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-minute walk test (29.5±5.1 vs 14.1±5.2 minutes; P=.04).

Limitations

  • Recall bias on HEI.
