We studied the contribution of physical load in daily activities, including activities in work, housekeeping, and leisure time, to the burden of low back problems (LBP) in the population.
Logistic regression models were used to calculate the association between physical load and several LBP parameters as assessed by questionnaire in a cross-sectional study on 22,415 randomly selected men and women in The Netherlands, controlling for well-known LBP determinants. The population attributable risk (PAR) percentage was estimated with the elimination method using the logistic model.
Half of the population reported LBP during the past year and 19% chronic LBP. Activities characterized by an awkward posture, by the same posture for a long time, or by often bending and rotating the trunk increased the risk for LBP, with ORs between 1.1 and 1.6. More than 13% of the 1-year prevalence of LBP could be contributed to these activities. This PAR was higher for those belonging to the working population, for women, and for the more severe LBP parameters.
Because LBP present such a large public health problem, the estimated potential impact of eliminating (the unhealthy effect of) physical load is substantial. To assess the real health gain, more insight is necessary into the causality of the relationship and into effective preventive measures.
我们研究了日常活动中的身体负荷，包括工作、家务和休闲活动中的负荷，对人群中腰痛问题（LBP）负担的影响。
在一项对荷兰随机选取的22415名男女进行的横断面研究中，使用逻辑回归模型计算身体负荷与通过问卷调查评估的几个LBP参数之间的关联，并对已知的LBP决定因素进行控制。使用逻辑模型的消除法估计人群归因风险（PAR）百分比。
一半的人群报告在过去一年中有腰痛，19%有慢性腰痛。以尴尬姿势、长时间保持同一姿势或经常弯腰和扭转躯干为特征的活动会增加患腰痛的风险，比值比在1.1至1.6之间。这些活动可导致超过13%的腰痛1年患病率。对于在职人群、女性以及更严重的LBP参数，这一PAR更高。
由于腰痛是一个重大的公共卫生问题，消除身体负荷（的不良影响）估计具有很大的潜在影响。为了评估实际的健康益处，有必要更深入地了解这种关系的因果关系以及有效的预防措施。
