BackgroundThe goals of this study were to (1) determine the feasibility and acceptability of using actigraphy to objectively measure sleep quality and habitual physical activity in rural Democratic Republic of Congo (DRC) and (2) examine the relationship between sleep parameters, self-report symptoms, daytime physical activity, and physical function, including the ability to work.MethodThirty individuals were asked to wear a wrist-worn accelerometer for 5 nights and 4 days. Nighttime sleep parameters derived were average and intra-individual variability (IIV) in total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE), and wake after sleep onset (WASO). Daytime habitual physical data derived were average and peak activity and daytime napping.ResultsNinety-three percent (n= 28) of participants completed the study. All participants who wore the device marked sleep and wake cycles and periods of non-wear using the marker. Trauma-related symptoms were not associated with mean or IIV in TST, SE, SOL, or WASO (p> 0.01). Those with higher levels of bodily pain slept longer (β= 0.633,p= 0.003, adjustedR2= 0.279), were more likely to report that their physical health limited their physical activities (β= 0.71,p< 0.001, adjustedR2= 0.679) and had greater difficulty doing daily work (β= 0.84,p= 0.001, adjustedR2= 0.665).ConclusionThe use of actigraphy to collect objective measures of activity and sleep quality in rural post-conflict settings is feasible and acceptable. Our preliminary findings suggest that bodily pain and not trauma-related symptoms have a significant impact on sleep and functional outcomes in men and women survivors of prolonged conflict in the DRC.

在受冲突影响的刚果民主共和国东部农村社区中使用活动记录仪评估生活在农村社区的男性和女性的习惯性身体活动和睡眠参数的可接受性和可行性

背景本研究的目标是 (1) 确定使用活动记录仪客观测量刚果民主共和国 (DRC) 农村地区的睡眠质量和习惯性身体活动的可行性和可接受性，以及 (2) 检查睡眠参数、自我报告之间的关系症状、白天的体力活动和身体机能，包括工作能力。方法要求 30 个人佩戴腕戴式加速度计 5 晚 4 天。得出的夜间睡眠参数是总睡眠时间 (TST)、入睡潜伏期 (SOL)、睡眠效率 (SE) 和入睡后醒来 (WASO) 的平均和个体内变异性 (IIV)。得出的白天习惯性身体数据是平均和峰值活动以及白天打盹。结果百分之九十三（n= 28) 的参与者完成了研究。所有佩戴该设备的参与者都使用标记标记睡眠和唤醒周期以及不佩戴时间。创伤相关症状与 TST、SE、SOL 或 WASO 的平均值或 IIV 无关（p> 0.01)。身体疼痛程度较高的人睡得更久（β= 0.633,p= 0.003，调整后R2= 0.279），更有可能报告他们的身体健康限制了他们的身体活动（β= 0.71,p< 0.001，调整后R2= 0.679) 并且在日常工作中遇到更大的困难 (β= 0.84,p= 0.001，调整后R2= 0.665).结论在冲突后农村地区使用活动记录仪收集活动和睡眠质量的客观测量是可行和可接受的。我们的初步研究结果表明，身体疼痛而非创伤相关症状对刚果民主共和国长期冲突的男性和女性幸存者的睡眠和功能结果有显着影响。
