Analysis of behavioral change techniques used in exercise and nutritional interventions targeting adults around retirement age with sarcopenic obesity in a systematic review
Archives of Gerontology and Geriatrics(2024)
Abstract
Background
Sarcopenic obesity significantly burdens health and autonomy. Strategies to intervene in or prevent sarcopenic obesity generally focus on losing body fat and building or maintaining muscle mass and function. For a lifestyle intervention, it is important to consider psychological aspects such as behavioral change techniques (BCTs) to elicit a long-lasting behavioral change.
Purpose
The study was carried out to analyze BCTs used in exercise and nutritional interventions targeting community-dwelling adults around retirement age with sarcopenic obesity. Methods. We conducted an analysis of articles cited in an existing systematic review on the effectiveness of exercise and nutritional interventions on physiological outcomes in community-dwelling adults around retirement age with sarcopenic obesity. We identified BCTs used in these studies by applying a standardized taxonomy.
Results
Only nine BCTs were identified. Most BCTs were not used intentionally (82%), and those used derived from the implementation of lifestyle components, such as exercise classes (“instructions on how to perform a behavior,” “demonstration of the behavior,” “behavioral practice/rehearsal,” and “body changes”). Only two studies used BCTs intentionally to reinforce adherence in their interventions.
Conclusions
Few studies integrated BCTs in lifestyle interventions for community-dwelling persons around retirement age with sarcopenic obesity. Future studies on interventions to counteract sarcopenic obesity should include well-established BCTs to foster adherence and, therefore, their effectiveness.
