Objective: This study aimed to investigate the incidence and risk factors for musculoskeletal injuries among junior badminton athletes during a national championship. Methods: A retrospective cohort study was conducted among 128 junior badminton athletes who were members of one Indonesian badminton club and participated in the National Premier Circuit held in June 2019 in West Java, Indonesia. Data on demographic characteristics, history of previous and current injuries, physical examination, diagnosis (type, anatomical structure involved, and location), and treatment of injuries were collected along with data on the format of the game (single, double, or combination), and the number of matches for each respective athlete. Measures of injury frequency used were the incidence proportion and clinical incidence. Determinant factors for incidence were investigated. Results: Twenty-four injury events involving 23 athletes were recorded, with an incidence proportion of 23/128 athletes (18%) and a clinical incidence of 24/128 athletes or 18.8 per 100 athletes. Acute injuries were more frequent (13/24, 54.2%) than chronic/overuse injuries. More than half (14/24, 58.3%) of the injuries occurred in the lower extremities. Factors that increased the risk of injury were age ≥ 15 years (relative risk [RR] = 6.26, 95% confidence interval [CI] 1.96, 20.04, p < 0.001), and the number of matches ≥ 3 (RR = 3.79, 95% CI 1.61, 8.92, p = 0.001). Conclusion Musculoskeletal injuries occurred frequently among Indonesian junior badminton athletes during the national elite championship. An effective injury-prevention program specific to young athletes should be developed to maintain their future participation and performance in competition.

INTRODUCTION: Lack of physical activity is a risk factor for dyslipidemia. Office work is a job associated with low physical activity. Wellness programmes in the workplace might increase physical activity and cardiorespiratory fitness. OBJECTIVE: This study aimed to determine the effect of a wellness programme on aerobic physical exercise adherence and blood lipid profile changes among government employees. METHODS: This study used a randomized controlled trial design, with the intervention (wellness programme) conducted for six weeks. Thirty participants who were office workers in a government institution were allocated into two groups. The intervention group (n = 15) received health education, aerobic physical exercise (30 minutes on a treadmill, three times/week for six weeks), reminders, and a logbook. The control group (n = 15) received education only. The outcomes were adherence to the exercise programme and lipid profile levels. RESULT: The intervention group showed more adherence to aerobic exercise than the control group (OR 42.2, 95% CI 5.1, 346.9). The mean (SD) total cholesterol level in the intervention group was decreased by 9.9 (21.1) mg/dl, while in the control group, it was increased by −16.0 (14.5) mg/dl at the end of the study (p = 0.010). The mean (SD) of low-density lipoprotein (LDL) cholesterol in the intervention group was also decreased by 0.9 (17.2) mg/dl while in the control group, it was increased by -14.8 (11.6) mg/dl (p = 0.007). No significant mean differences were observed for high-density lipoprotein (HDL) cholesterol and triglyceride. CONCLUSION A workplace wellness programmes can enhance employees’ adherence to physical exercise and decrease their total blood cholesterol and LDL level.

INTRODUCTION: Offshore and onshore workers have a higher risk of psychological stress related to their job. Stress reactions vary depending on the type of stressor, the duration or severity of the stressor, their genetics, their coping styles, and their nutrition. Tryptophan is an essential amino acid precursor of serotonin and melatonin, which have an antidepressant effect and roles in stress perception and management. This study assessed the correlation of daily tryptophan intake and occupational factors with stress outcome scores based on the Indonesian Short Version New Brief Job Stress Questionnaire (SV-NBJSQ) among offshore and onshore workers. METHODS: A cross-sectional study was conducted on 14 offshore workers and 20 onshore workers. Interviews and questionnaires were conducted to obtain demographic data, dietary intake, occupational factors, and stress outcome scores. Tryptophan daily intake was measured through a single 24-hour dietary recall and a one-day-weighted food record. Data of average daily intake for two days were analyzed using the NutriSurvey software based on the food composition table from The United States Department of Agriculture National Nutrient Database for calculating tryptophan intake. RESULTS: The median (min-max) tryptophan daily intake of offshore workers was 5.5 (1.9–9.9) mg/kg, and 4.5 (1.4–7.5) mg/kg among onshore workers. There was no difference in tryptophan daily intake between offshore and onshore workers (p = 0.064). There was no significant difference between occupational factors except for the shorter tenure of offshore workers (12.5 vs 3, p < 0.001). There was no significant correlation between tryptophan daily intake and each of the stress outcome scores. There was a significant correlation between occupational factors and stress outcome scores among offshore and onshore workers, specifically between workload and fatigue (r = 0.35, p =0.04), workload and depression (r = 0.4, p = 0.02), interpersonal conflict and anxiety (r = 0.47, p = 0.005), role conflict and anxiety (r = 0.47, p = 0.005), as well as between tenure and physical reaction stress (r = -0.42, p = 0.02). CONCLUSION Adequate tryptophan daily intake and high stress outcome scores among offshore and onshore oil and gas workers are observed in this study, and no correlation was found between the two. Similar food sources, homogeneous occupational stressors, the selection bias of the “healthy worker effect” or other factors that were not studied may influence the findings. There is a correlation between occupational factors and stress outcome scores, namely workload and fatigue, workload and depression, interpersonal conflict and anxiety, role conflict and anxiety, and tenure and stress physical reactions.
