Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Acne vulgaris is a common skin disorder among medical students. Proper facial cleansing habits may influence the occurrence of acne vulgaris. To examine the relationship between facial cleansing habits and the occurrence of acne vulgaris among 2022 cohort students at the Faculty of Medicine, University of Muhammadiyah North Sumatra. This analytic cross-sectional study involved 156 students enrolled through consecutive sampling. Facial cleansing habits were assessed using a validated closed-ended questionnaire, while acne vulgaris occurrence was determined through direct clinical inspection by a dermatology specialist. Data were analyzed using Chi-Square test at significance level p < 0.05. A total of 55.8% demonstrated adequate facial cleansing habits, while 41.0% experienced acne vulgaris. Statistical analysis indicated a significant association between facial cleansing habits and acne vulgaris occurrence (p = 0.012). There is a significant relationship between facial cleansing habits and acne vulgaris occurrence. Proper facial cleansing habits may serve as a practical non-pharmacological strategy to prevent acne vulgaris.
