Behaviour therapy for obesity in older adults

•Obesity rates increase with age, and its prevalance among older adults shows a rising trend over the years.•Behaviour therapy is central to obesity management and may require adaptation for older adults due to cognitive and physical challenges. However the current evidence about this topic is quite insufficient.•Emerging digital behavioral interventions provide innovative strategies for obesity management, but further evidence is needed to assess their effectiveness in older populations.•More research is required to develop and evaluate tailored behavioral therapies for older adults, focusing on diverse populations and considering their unique physical, cognitive, and social needs. Obesity presents a significant public health challenge, with a growing prevalence among older adults and addressing obesity in older adults presents unique challenges. Behaviour therapy is a cornerstone in obesity management, yet its application in older populations, is underexplored. This narrative review, based on the current literature, examines the role of behavioural change techniques (BCTs) in addressing obesity in older adults, highlighting the need for tailored interventions that consider age-related challenges. BCTs are integral in promoting long-term behaviour change, enhancing self-management, and ensuring adherence to treatment plans. While existing evidence suggests the efficacy of several BCTs such as self-monitoring, goal setting, motivational interviewing, and social support in obesity management, further research is needed to understand their impact in older age groups with multimorbidity and combinations of geriatric syndromes. The impact of these techniques may vary based on factors such as patients’ clinical features, cognitive function, sensory deficits, social factors and psychological aspects unique to aging individuals. Therefore, the design and implementation of BCTs in this population require careful evaluation and customization. Tailored interventions that consider the unique needs of this population, such as preserving muscle mass and addressing functional limitations, are essential. Future research should focus on large-scale, well-designed trials to elucidate the optimal BCTs for older individuals, ensuring interventions are diverse and inclusive to meet the needs of older adults with obesity.
