Obesity, characterized by excessive accumulation of body fat, increases susceptibility to chronic disease and adversely impacts overall quality of life. Elderly people often exhibit higher fat mass and lower muscle mass and bone density, influenced by reduced physical activity, hormonal changes, and metabolic adjustments. Visceral fat accumulation is of particular concern because of its association with metabolic syndrome, insulin resistance, diabetes, hypertension, and cardiovascular disease. This activity uses the PDCA (Plan-Do-Check-Act) framework to screen for obesity in the elderly using Body Mass Index (BMI) and waist circumference measurements. Activities were held at St. Fransiskus Assisi, Jakarta involving 36 participants. The study revealed that 16 participants (44.5%) and 30 people (83.3%) were obese and centrally obese, respectively. Early detection and intervention through anthropometric measurements are very important in managing health risks related to obesity in the elderly, so as to improve their quality of life and reduce morbidity and mortality.

Sarcopenia is a progressive degenerative condition characterized by a decrease in muscle mass, strength, and musculoskeletal function, affecting the quality of life of the elderly. This activity aims to screen for vitamin D and educate the elderly about sarcopenia. Community service activities were carried out in nursing homes, involving education and screening of vitamin D levels. The results showed that the majority of respondents were women (79.6%) with an average age of 74.05 years. Most respondents experienced vitamin D deficiency, with 87.1% deficient, 3.2% adequate, and only 9.7% having good levels, with it being found that more women experienced vitamin D deficiency than men. Education regarding the importance of vitamin D and preventing sarcopenia is provided through outreach sessions and poster media. This activity emphasizes the importance of early detection and comprehensive intervention including physical exercise, proper nutritional intake, and lifestyle modification to prevent sarcopenia and improve the quality of life of the elderly. Community-based interventions are needed to address vitamin D deficiency and promote musculoskeletal health in the aging population.
