Abstract

Obesity can cause chronic oxidative stress. Oxidative stress occurs when the formation of free radicals is greatly increased or the protective antioxidant mechanisms are disrupted. Previous studies have concluded that there is a relationship between oxidative stress and excess body weight and obesity. One of the products of oxidative stress is malondialdehyde (MDA). This study aims to determine the correlation between malondialdehyde (MDA) levels and body mass index (BMI), waist circumference (LP), and body fat percentage. The subjects were 55 students of the Medical Education Study Program, Faculty of Medicine, University of Mataram, class of 2021. The BMI variable was calculated by dividing body weight (kg) by the square of height (m), waist circumference was measured using a tape measure (cm), and body fat percentage measured by body composition monitor (%). Serum MDA levels were measured using the ELISA method. Data were analyzed statistically with the Spearman correlation test. The results showed that the average MDA level in subjects with overweight and obesity was higher than normal, however there was no significant correlation between body mass index, waist circumference, and body fat percentage with MDA levels, with each significance value :p=0.230; p=0.276; and p=0.666. Body mass index, waist circumference, and body fat percentage cannot be ruled out as risk factors for oxidative stress.

Abstract

Introduction: Diving-related injuries remain a major occupational health risk among coastal fishermen. It is crucial to examine health-seeking behavior among traditional diving fishermen to improve prevention strategies and early management for this high-risk occupational group. Methods: This qualitative study used purposive sampling. The participants were 17 active or former diving fishermen and 13 healthcare workers from coastal primary healthcare centers (Puskesmas) across Lombok Island, Indonesia. Data were collected through focus group discussions and analyzed thematically using Andersen's predisposing, enabling, and perceived need framework. Results: The health-seeking behavior of traditional diving fishermen is influenced by their perception of the severity of diving-related injuries, referred to as perceived need. Predisposing factors include the normalization of occupational risks based on empirical experience, culturally influenced interpretations of symptoms, and peer support. Enabling factors include the cost of treatment, perceptions of unclear referral pathways, and previous negative experiences with primary healthcare services. Healthcare providers also acknowledged that their capacity to manage diving-related injuries remains limited. Conclusion: The interaction of occupational risk normalization, perceived need, and healthcare system barriers appears to contribute to delayed healthcare utilization among traditional diving fishermen. These factors suggest that the limited use of formal healthcare services is more likely to reflect substantial underreporting than a genuinely low incidence of diving-related injuries. These findings highlight the need for coordinated multilevel interventions to improve timely healthcare utilization in this high-risk occupational group.
