Managing sarcopenic obesity in older adults through diet and exercise
Effects of an Individualized Dietary Behavioural Change (IDBC) Programme and Exercise Training in Combination or Separately on Managing Sarcopenic Obesity in Community-dwelling Older Adults: A Randomized Controlled Trial
This study is testing whether changes in diet and exercise can help older adults with sarcopenic obesity build muscle and lose fat.

What this trial studies
This study investigates the effects of a dietary behavioral change program and exercise training on managing sarcopenic obesity in older adults. It aims to improve muscle mass and reduce fat mass by incorporating behavior change techniques based on the Health Action Process Approach (HAPA) model to enhance participants' self-efficacy. The study will include community-dwelling older individuals aged over 65 who meet specific diagnostic criteria for sarcopenic obesity. Participants will engage in either dietary interventions, exercise training, or a combination of both to assess the most effective approach.
Who should consider this trial
Good fit: Ideal candidates for this study are community-dwelling older adults aged over 65 who meet the diagnostic criteria for sarcopenic obesity.
Not a fit: Patients who do not meet the diagnostic criteria for sarcopenic obesity or have significant hearing and vision problems may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved health outcomes and quality of life for older adults suffering from sarcopenic obesity.
How similar studies have performed: While there have been limited trials focusing on sarcopenic obesity, the approach of combining dietary and exercise interventions is promising and has shown success in related areas.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: 1. community-dwelling older people aged \> 65 years 2. who meet the diagnostic criteria of sarcopenic obesity according to the Asian Sarcopenia Working Group (ASWG)41 and the WHO definition of obesity for the Asian population, respectively: 2a) Early stage sarcopenia refers to the fulfillment of one of the following criteria: low handgrip strength \< 28 kg for men and \< 18 kg for women, low muscle quality as reflected by low appendicular skeletal muscle mass (ASM) /height squared \< 7 kg/m2 for men and \<5.7 kg/m2 for women, or low physical performance with a Short Physical Performance Battery (SPPB) score of \< 9; 2b) Obesity refers to the fulfillment of one of the following criteria: BMI ≥ 23kg/m2 or waist circumference ≥ 90 cm in men and ≥ 80 cm in women, or percentage of body fat \> 30%; 3. able to communicate, read, and write in Chinese without significant hearing and vision problems to ensure that our instructions are understood. Exclusion Criteria: 1. those with any form of disease or condition that might affect food intake and digestion (such as severe heart or lung diseases, renal diseases, diabetes, cancer, or autoimmune diseases); 2. taking medications that may influence eating behaviour, digestion, or metabolism (such as weight loss medication); 3. being addicted to alcohol, which might affect the effort to change dietary behaviour; 4. having impaired mobility, which might affect participation in exercise training, as defined by a modified Functional Ambulatory Classification score of \< 7; ) having any medical implant device such as a pacemaker, because low-level currents will flow through the body when doing the bioelectric impedance analysis (BIA by InBody s10, Korea), which may cause the device to malfunction.
