背景和目标：背痛是在美国提出工人赔偿索赔的最常见原因，并影响许多其他国家的大量工人。为了评估重复活动的工作时间与背痛之间的关联，对 1988 年全国健康访谈调查收集的数据进行了分析。该数据还用于识别高风险职业。方法：共有30 074名工人参与了调查。他们被要求提供有关其工作的信息，包括在典型工作中重复进行剧烈体力活动所花费的时间 (RSPA) 以及重复弯曲、扭转或伸展所花费的时间 (RBTR)。背痛病例被定义为在过去 12 个月内每天都有背痛、持续一周或更长时间的工人。每个病例都被要求报告背痛的原因。那些将背痛归因于重复活动 (RA) 或单次事故或伤害 (AI) 的人被要求回忆自己是否进行了 RA 或在工作中进行了 Al。 结果：虽然背痛的患病率随着 RSPA 或 RBTR 工作时间的增加而增加，但任一因素的剂量反应关系都不是线性的，这表明还涉及其他未测量的因素。据估计，男性工人中 RA 背痛的总体患病率为 8.9%，女性工人中为 5.9%。男性主要职业中，“木匠”患病率最高（19.2%），病例最多（33.8万例）；女性主要职业中，“护工、勤务员、服务员”患病率最高（15.2%），病例最多（21.7万例）。结论：工作中重复活动的小时数与背痛患病率相关。本研究确定了高危职业，有利于今后的研究和干预。
Background and Aims: Back pain is the most common reason for filing workers' compensation claims in the United States and affects large numbers of workers in many other countries. To evaluate the associations between working hours spent on repeated activities and back pain, data gathered through the 1988 National Health Interview Survey were analysed. The data were also used to identify high risk occupations.Methods: A total of 30 074 workers participated in the survey. They were asked to provide information on their job, including the time spent on repeated strenuous physical activities (RSPA) and the time spent on repeated bending, twisting, or reaching (RBTR) on a typical job. A case of back pain was defined as a worker who had back pain every day for a week or more during the past 12 months. Each case was asked to report the cause of back pain. Those who attributed their back pain to repeated activities (RA) or a single accident or injury (AI) were asked to recall whether they performed RA or had the Al at work.Results: Whereas the prevalence of back pain increased as the number of working hours spent on RSPA or RBTR increased, the dose-response relations were not linear for either factor, suggesting the involvement of other unmeasured factors. The estimated overall prevalence of RA back pain was 8.9% among male workers and 5.9% among female workers. "Carpenters" had the highest prevalence (19.2%) and most cases (338 000) among the major occupations of men, and nursing aides, orderlies, and attendants" had the highest prevalence (15.2%) and most cases (217 000) among the major occupations of women.Conclusions: The number of hours spent on repeated activities at work was associated with the prevalence of back pain. This study identified high risk occupations for future research and intervention.
