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.

Skin diseases are a common problem among people, especially teenagers. Hormones, lifestyle and personal hygiene play a role in the occurrence of various skin problems in teenagers. If not treated, it can cause various disorders, especially quality of life. This health education was carried out to all class X students of SMA Kalam Kudus II Jakarta using the counseling/seminar method. In addition to enhancing knowledge, this education may provide awareness to teenagers to pay attention to their skin health so that various skin diseases can be avoided. Furthermore, it is hoped that this can become a basis for society to maintain healthy skin, so that the incidence of skin diseases in the community can be reduced.

Colorectal carcinoma, a malignant neoplasm originating from the epithelial cells of the large intestine or rectum, poses a significant health problem worldwide. The estimated global incidence of colorectal cancer was 2.17 million cases in 2019. Meanwhile, in Indonesia, colorectal cancer ranks fifth among the most common cancer cases with a mortality rate of 9.5%. Demographic characteristics, including age, gender, ethnicity, and geographic location, have been extensively studied in relation to colorectal carcinoma. Understanding the patterns of differentiation and demographic characteristics associated with this disease is crucial for the diagnosis, treatment, and overall prognosis of patients. This study is a descriptive observational study that examines the demographic characteristics and differentiation of colorectal carcinoma patients. The study sample consists of a subset of the research population at Ciawi Regional General Hospital who underwent surgery from June 2021 to May 2023. A total of 21 respondents met the inclusion criteria, with a mean age of 54 years, and were predominantly female (57.1%). The results of this study indicate that poorly differentiated colorectal carcinoma generally occurs at a younger age compared to well and moderately differentiated cases. In terms of gender, females are more likely to experience colorectal carcinoma compared to males. Further research is needed to uncover the interactions between tumor biology, demographics, and clinical outcomes, with the ultimate goal of improving the prognosis and survival rates for individuals with colorectal carcinoma.
