Background: Hand grip strength is an essential indicator of physical capacity and nutritional status that can identify obesity risk. Adipose tissue accumulation in central obesity contributes to decreased hand grip strength quality through impaired muscle force transmission. Previous studies showed inconsistent results regarding the relationship between waist circumference and hand grip strength, especially in populations with high physical activity. Objective: To analyze the relationship between waist circumference and hand grip strength in male construction workers with high physical activity in Medan City. Methods: This descriptive-analytic study with cross-sectional design involved 100 male construction workers aged 30-39 years selected using purposive sampling technique. Waist circumference was measured using measuring tape, while hand grip strength was measured using handgrip dynamometer. Data analysis used Chi-Square test with significance level α=0.05. Results: The majority of respondents had normal waist circumference (64%) with mode 70 cm and normal grip strength category (53%) with mode 41.7 kg. Chi-Square test showed significant relationship between waist circumference and hand grip strength (p=0.039). Conclusion: There is a significant relationship between waist circumference and hand grip strength in construction workers. High physical activity does not completely prevent central obesity, therefore nutritional management and health education programs are needed for optimization of body composition and muscle functional capacity.

Introduction: Maximal oxygen volume (VO2max) is the capability of the cardiorespiratory system to deliver oxygen to muscle mitochondria, which is directly proportional to the level of stamina and is obtained from physical activity. Central obesity, which is characterized by excessive accumulation of visceral fat, can cause decreased stamina, so individuals with central obesity tend to have lower VO2max values. VO2max values can be determined by body composition, such as waist circumference, which is an indicator of central obesity. Methods: This study used an observational analytical design with a cross-sectional approach and involved 54 male respondents with high physical activity jobs who worked as building construction workers in Medan City, North Sumatra Province. Waist circumference measurements were carried out using a measuring tape, while VO2max was assessed using a 6-minute walk test. Statistical analysis was performed using the Spearman correlation test with a significance level of 0.05. Results: A total of 47 respondents (87%) had a normal waist circumference, 31 respondents (57.4%) had a fair VO2max, and 16 respondents (29.6%) had an average VO2max. The analysis showed a significant relationship between waist circumference and VO2max, with a P value of 0.000 (P<0.05) and R = -0.658. Conclusion: There is a strong and significant negative correlation between waist circumference and VO2max. This indicates that a larger waist circumference results in a lower VO2max, and a smaller waist circumference results in a higher VO2max.

Background: Hyperuricemia represents a medical condition marked by elevated concentrations of uric acid within the bloodstream, potentially triggering gout alongside various metabolic disorders. Central obesity has been identified as a contributing factor to rising uric acid concentrations, measurable through waist circumference assessment. Methods: An analytic observational design utilizing a cross-sectional approach was employed in this investigation, encompassing 100 male participants characterized by sedentary lifestyles who were employed as office workers in Medan City, North Sumatra Province. Waist circumference measurements were obtained using a flexible measuring tape, while uric acid concentrations were determined through Point of Care Test (POCT) devices. Statistical evaluation was conducted via the Chi-Square test, applying a significance threshold of 0.05. Results: Among all participants, 64 individuals (64%) exhibited waist circumference measurements indicative of central obesity, whereas 56 individuals (56%) demonstrated hyperuricemic conditions. Statistical evaluation revealed a significant association between waist circumference measurements and uric acid concentrations, evidenced by a p-value of 0.000 (p < 0.05). Conclusion: A meaningful correlation exists between waist circumference and uric acid concentrations among males engaged in sedentary occupations.

Non-communicable diseases (NCDs), such as hypertension, diabetes mellitus, and obesity, pose significant health risks for the elderly in Indonesia, including those in Aneuk Paya Village, Lhoknga District, Aceh Besar. These conditions, if left unmanaged, can lead to severe complications, impacting the quality of life of older adults. This community service project aims to improve elderly individuals' understanding of NCDs, as well as their prevention and management, through educational initiatives carried out at the Integrated Health Post (Posbindu). The activities involved interactive counseling sessions, health assessments including blood pressure monitoring, and measurements of body weight, height, waist circumference, blood sugar, and cholesterol levels. The community service event, conducted on July 22, 2025, revealed a significant improvement in the elderly participants’ knowledge about NCDs. Notably, 83% of the participants gained a better understanding of the prevention of NCDs, while 70% reported improved knowledge regarding blood sugar and blood pressure management. Moreover, there was a noticeable increase in the number of elderly individuals attending regular Posbindu visits, which suggests a growing commitment to managing their health. Health education through Posbindu has proven to be an effective tool in raising awareness and changing health behaviors among the elderly, helping to prevent NCD complications. The project demonstrates the pivotal role of Posbindu not only in promoting NCD prevention but also in providing continuous support to the elderly in managing their health, ultimately enhancing their quality of life. This initiative highlights the importance of local health programs in addressing the growing prevalence of NCDs in elderly populations and emphasizes the need for further community-based health interventions.

Non-Communicable Disease (NCD) Screening is an early effort to identify NCD risk factors in individuals or groups through the Integrated Development Post (Posbindu) NCD. NCDs consist of Hypertension, Diabetes Mellitus, Cervical and Breast Cancer, and Chronic Obstructive Pulmonary Disease. NCDs are increasing and are the main cause of death of the population. In 2030, it is targeted that at least the number of premature deaths due to NCDs can be prevented through the SDGs program by 25%. The Faculty of Health Sciences (Fikes) of Musi Charitas Catholic University (UKMC) is part of the Sukarami Health Center Working Area which has 396 students in the 2024/2025 academic year. Fikes finds out whether or not there are NCD risk data factors in students. Lecturers and Officers of the Sukarami Health Center are actively conducting NCD screening using the Posbindu activity method, namely 5 Tables (Registration, Interview, Measurement, Examination and Counseling/Education). The target of all UKMC Fikes students who are studying on campus is 287 (72.47%). The activities carried out were measuring Body Weight (BB), Height (BB), determining Body Mass Index (BMI). Implementation of procedures in accordance with the guidelines set by the Indonesian National Nurses Association (PPNI). Results: The target achievement was 245 (85.37%) of the original target of 287. Analysis results 1) Students who have a BMI > 25 are 72 (29.39%) students; have a waist circumference > 80 (women) and > 90 (men) are 62 (25%) students. Blood pressure > 130/90 mmHg is owned by 6 (2.45%) students, while random blood sugar > 180 mg/dl is owned by 1 (0.41%) student. Suggestions or Follow-up Action Plans: All students are screened periodically and PTM control is carried out.

Metabolic syndrome, encompassing hypertension, elevated blood glucose levels, high cholesterol, and increased waist circumference, is a significant risk factor for frailty in older adults. The FRAIL questionnaire is a screening tool that assesses five components of frailty, enabling early detection for appropriate intervention. This community service program was conducted using the PDCA (Plan-Do-Check-Act) method with 93 elderly participants. Health education and screening for metabolic syndrome and frailty were performed using the FRAIL questionnaire. Among the participants, 22.58% were categorized as "Non-Frail," 50.54% as "Pre-Frail," and 26.88% as "Frail." These findings indicate a high prevalence of frailty risk among the elderly population. The FRAIL questionnaire proved effective for early detection of frailty, facilitating preventive interventions such as physical activity, nutritional monitoring, comorbidity management, and psychosocial support. These measures have the potential to sustain long-term health in older adults. The application of the FRAIL questionnaire for the elderly provides significant benefits for managing frailty risk, with a sustainable approach that promotes the well-being of older adults.

The study was to describe the nutritional status of participants in the Integrated Development Post for Non-Communicable Diseases. The method used was descriptive quantitative with 35 respondents. Respondents were measured anthropometrically including weight, height, waist circumference and body mass index (BMI) then descriptive analysis was carried out using SPSS. The results showed that respondents who had BMI in the obesity category were 15 (42.90%), normal 14 (40%) and obese 6 (17.10%) and based on the measurement of waist circumference, respondents who experienced central obesity were 30 (85.70%) and not central obesity were 5 (14.30%). Conclusion: Maintaining nutritional status is very beneficial because someone who is overweight is at risk of experiencing several diseases such as hypertension, diabetes mellitus and heart disease.

Obesity in children and adolescents is a global health problem, with increasing prevalence in low- and middle-income countries and consistently high obesity rates in high-income countries. Obesity, characterized by excessive lipid accumulation, is primarily caused by an energy imbalance resulting from high caloric intake and inadequate expenditure. This activity uses the PDCA (Plan-Do-Check-Act) methodology, involving 167 participants for obesity screening. The results of measuring Body Mass Index and waist circumference showed that 14 (8.39%) people were obese level II, 22 (13.18%) people were obese level I, 13 (7.79%) people were overweight, and 53 ( 31.74%) people have a risk of central obesity. Early detection through routine anthropometric assessments allows timely intervention, including lifestyle modifications to prevent obesity and related comorbidities, thereby improving overall health outcomes.

Abstract: Obesity is a global epidemic and a significant public health problem. In the elderly population, obesity is defined as a BMI ≥ 25 kg/m². In the United States, the prevalence of obesity among the elderly is 37.1% in men and 33.6% in women over the age of 60. Obesity increases the risk of chronic diseases such as type 2 diabetes, hypertension and cardiovascular disease, and can cause psychological problems such as sleep disorders and lack of self-confidence. Accurate obesity risk assessment involves measuring Body Mass Index (BMI) and waist circumference. This activity uses the Plan-Do-Check-Act (PDCA) methodology to screen for obesity in the elderly at Hana Nursing Home, South Tangerang. The screening includes anthropometric measurements of BMI and waist circumference, followed by evaluation and nutritional counseling for at-risk individuals. 9 people (14.75%) had overweight nutritional status, 3 people (4.92%) had obese nutritional status, and 35 people (57.38%) were at risk of central obesity. Routine anthropometric measurements are critical for monitoring obesity and implementing preventive measures to improve overall health outcomes, improve quality of life, and reduce obesity-related morbidity and mortality rates.

Coronary artery disease (CAD) is a significant cardiovascular disease that affects the human population worldwide. There are several risk factors that contribute to the development of this cardiovascular disease, including lifestyle, environmental factors, and genetic factors. This survey study aims to examine the characteristics of age, gender, blood pressure, body mass index, hip circumference, waist circumference, and arm circumference in the normal EKG group, EKG suspect coronary artery disease group, and the total research sample at SMA Kalam Kudus II Jakarta, selected based on total sampling criteria during the period of May - June 2023. The variables used in this study are age, gender, blood pressure, body mass index, hip circumference, waist circumference, arm circumference, and electrocardiogram (ECG) examination. All examinations were conducted according to standard procedures and protocols. Among the 52 respondents, the characteristics of the respondents in terms of gender, age, blood pressure, body mass index, hip circumference, waist circumference, and arm circumference were not significantly different among the normal EKG group, EKG suspect CAD group, and the total sample.

Counseling activities and waist circumference screening in the context of early detection of obesity in male students aim to increase awareness of the importance of maintaining health and preventing obesity among male students. This activity was carried out using a combination approach between counseling and waist circumference screening. The counseling was conducted to provide a better understanding of the risk of obesity and the importance of measuring waist circumference as an indicator of health. Boys were given information about the negative impact of obesity on physical and psychological health, as well as the importance of a healthy lifestyle and a balanced diet. In addition to counseling, this activity also involves screening waist circumference as a method for early detection of the risk of obesity. Boys' waist circumference was measured using a measuring tape, and the measurement results were compared with a predetermined reference standard. This helps identify students who are in the waist circumference range who are at risk and require further follow-up in obesity prevention and management. The results of this activity show that male students need to understand the importance of maintaining health and managing their weight well. Waist circumference screening provides useful information in evaluating the risk of obesity in male students. In efforts to prevent and control obesity, collaboration between families, educators and medical personnel is very important to provide the necessary support, understanding and guidance
