This study compared the body composition parameters between shiftworkers and nonshiftworkers in a hospital setting in Sri Lanka.
A comparative cross-sectional study was carried out among a sample of 78 health care workers, recruited by a stratified random sampling technique. Subjects underwent anthropometric and bioimpedentiometric analysis for body composition parameters.
The mean (SD) body fat percentage (BF%) of shiftworking women (40.8 [SD, 6.8%]) was significantly higher than day-working women (36.7% [SD, 5.9%]) ( P < 0.05). Mean BF% between day and shift groups did not significantly differ (33.0% [SD, 6.9%] vs 32.4% [SD, 10.7%]). Body mass index and waist circumference were significantly higher among shiftworking women ( P < 0.05), whereas male workers showed the opposite trend.
Prolonged exposure to shiftwork was associated with a higher BF%. Therefore, interventions for shiftworkers must be addressed, focusing on improving body composition.
本研究比较了斯里兰卡某医院中轮班工人和非轮班工人的人体成分参数。
采用分层随机抽样技术，对 78 名医护人员进行了一项横断面比较研究。对受试者进行人体测量学和生物电阻抗分析，以获取人体成分参数。
轮班女性（40.8%[标准差，6.8%]）的体脂百分比（BF%）均值显著高于日班女性（36.7%[标准差，5.9%]）（P<0.05）。日间组和轮班组之间的 BF%均值无显著差异（33.0%[标准差，6.9%]与 32.4%[标准差，10.7%]）。轮班女性的体重指数和腰围明显更高（P<0.05），而男性工人则表现出相反的趋势。
长时间暴露于轮班工作与较高的 BF%有关。因此，必须针对轮班工人采取干预措施，重点改善其身体成分。
