Vitamin D deficiency is a condition that often goes unnoticed but has widespread health implications, particularly among the adult population. Through this community service activity, vitamin D levels were screened in 49 adult participants in the Danau Sunter area using serum 25(OH)D testing, accompanied by education on the importance of vitamin D, its natural sources, and strategies for preventing deficiency. The results showed variation in vitamin D levels among participants, with a mean of 59.13 ng/mL and a range of 26.6–91.8 ng/mL. A total of 3 participants (6.12%) were found to have vitamin D deficiency. Several individuals were identified as being in the deficiency category, requiring further intervention. The educational component played an important role in increasing participants’ awareness and understanding of the role of vitamin D in preventing musculoskeletal and metabolic complications. This program successfully identified individuals in the community with vitamin D deficiency and improved knowledge regarding its prevention.

Dermatoporosis is a chronic skin fragility syndrome common in the elderly, characterized by thinning of the skin that increases the risk of injury, bruising, and delayed wound healing. Chronic hyperglycemia and poor glycemic control have been reported to be associated with an increased risk of dermatoporosis. This community service activity aims to screen blood sugar levels, HbA1c, and dermatoporosis and educate the elderly using the Plan-Do-Check-Act (PDCA) method at Panti Bina Bhakti, South Tangerang. This activity involved 93 elderly participants aged >65 years. Meanwhile, based on the results of the HbA1C examination, 52 people had moderate glycemic control and 24 people had poor glycemic control. The results of the dermatoporosis examination have not been included. Early intervention through education and monitoring of blood sugar levels can reduce the risk of dermatoporosis, improve the health of the elderly's skin, and reduce the burden of health care.
