ANZBMS Webinar: Sarcopenic obesity, bone and muscle health following weight loss treatments

Older adults living with "sarcopenic obesity" (coexisting sarcopenia [low muscle mass and strength] and obesity) have poorer bone mineral density and increased risk of falls and fractures compared with counterparts with obesity alone. While weight loss is likely to have cardiometabolic health benefits for older adults with sarcopenic obesity, its effects on their bone and muscle health, given their pre-existing increased risk for fractures, is a cause for concern.

Indeed, weight loss, even in older adults with obesity but not sarcopenia, leads to significant declines in bone and muscle mass, particularly following bariatric surgery and medical weight loss interventions. This presentation will explore the associations of sarcopenic obesity with musculoskeletal health, and the effects of weight loss interventions on bone and muscle mass and quality.

Strategies to identify sarcopenia in individuals with obesity in the clinic will be discussed. Furthermore, this presentation will guide approaches to improving muscle and bone health in those with sarcopenic obesity and for mitigating muscle and bone loss during weight reduction, including the prescription of resistance training and nutrition.

Dr. David Scott PhD is an Associate Professor and National Health and Medical Research Council Emerging Leadership Fellow with the Institute for Physical Activity and Nutrition at Deakin University in Melbourne, Australia. His research focuses on the epidemiology, diagnosis, and management of sarcopenia (the age-related decline in muscle mass and function), and its interactions with obesity and osteoporosis in older adults.

He has expertise in assessing physical activity and physical performance in older adults, as well as imaging techniques for estimating body composition and bone health. He has led several clinical trials of exercise and nutrition for maintaining and improving physical function during ageing, and his recent work explores the role of digital health in supporting older adults to self-manage musculoskeletal health conditions.

He has published over 230 journal articles and books and has received over $6M in competitive research funding. He is the inaugural chair of the Australian and New Zealand Society for Sarcopenia and Frailty Research's Sarcopenia Diagnosis and Management Task Force, and an elected member of the International Osteoporosis Foundation's Committee of Scientific Advisors.
