A combination of remote, supervised aerobic training, resistance training, and a hypocaloric diet significantly improved cardiovascular risk factors in adults with rheumatoid arthritis (RA) and overweight or obesity.
- The researchers recruited 24 adults aged 60-80 years with RA who met criteria for overweight or obesity; participants were randomized to a Supervised Weight Loss and Exercise Training (SWET) or Counseling Health as Treatment (CHAT) program for 16 weeks.
- The SWET intervention included remote supervision of aerobic training of 150 minutes/week moderate-to-vigorous intensity, 2 days per week of resistance training, and a hypocaloric diet based on a weight loss goal of 7% of body weight. The CHAT patients served as controls and completed two lifestyle counseling sessions followed by monthly check-ins.
- The primary outcome was change in a composite measure of cardiovascular risk based on metabolic syndrome z-score (MSSc), a continuous weighted score of five metabolic syndrome components: Waist circumference, mean arterial blood pressure, fasting glucose, triglycerides, and high-density lipoprotein cholesterol.
- Both groups showed improvement in the primary outcome of MSSc, with absolute changes from baseline of −1.67 for the SWET group and −1.34 for the CHAT group (P
- Participants in the SWET group showed significantly more improvement in secondary outcome measures of body weight, fat mass, and disease activity score in 28 joints based on C-reactive protein (DAS28-CRP), as well as greater improvement in patient-reported physical and mental health, physical function, and fatigue, than those in the CHAT group, but the CHAT group improved significantly compared with their baseline.
- The strongest specific effects for the different components of the intervention were those of aerobic training on physical function and fatigue, resistance training on DAS28-CRP, and weight loss on MSSc.
- Neither group experienced significant changes in lean mass, absolute peak V02, unilateral isometric knee extension, or bilateral grip strength.
“Findings from our study indicate, at a minimum, integrating even 2 hours of healthy lifestyle counseling may improve RA management, let alone demonstrate the substantial impact that can be provided by a comprehensive, remotely supervised lifestyle intervention,” the researchers wrote.
The lead author on the study was Brian J. Andonian, MD, of Duke University, Durham, North Carolina. The study was published online on December 21, 2023, in ACR Open Rheumatology.
The small sample size was a limitation of the study findings, as was the lack of blinding and high level of motivation in the CHAT group, who had greater improvements than expected in weight loss and increased physical activity; the study also was conducted during the COVID-19 pandemic, with potential physical and mental effects on participants who tested positive during the study period.
The study was supported by the US National Institute of Arthritis and Musculoskeletal and Skin Diseases and the Claude D. Pepper Older Americans Independence Center of the US National Institute on Aging.
