Low back pain (LBP) is one of the main causes of disability and need for rehabilitation services. It is necessary to have a better understanding about the association of sociodemographic factors with the disability related to individuals with LBP.
Assess the prevalence of LBP and its association with capacity, performance, and sociodemographic variables in Chilean population.
Cross-sectional study was performed with data from the population survey from Chile, 2015. People over 17 years old were selected for the analysis (n = 12,265 people). The variables chosen were: presence of LBP, place of living in Chile, sex, age, marital status, education, income, work status, and type of home. Capacity and performance levels were assessed by the Model Disability Survey. The population characteristics, performance, and capacity values were presented through means or frequencies. A generalized linear model with logarithmic linkage and gamma distribution was employed to assess the associations between the explanatory variables and the outcomes, considering the distribution of the variables, while adjusting for all study variables.
22 % of the population reported having LBP. People with LBP had worse levels of capacity and performance. Being female, older age, having worse education level, and worse health classification, were factors associated with worse capacity and performance in those with LBP. Conversely, being employed in the last week was correlated with improved capacity in this group.
Individuals with LBP demonstrated poorer capacity and performance outcomes, with sociodemographic variables influencing their functioning.
腰痛（LBP）是导致残疾和需要康复服务的主要原因之一。有必要更好地了解社会人口学因素与腰痛患者残疾之间的关联。
评估智利人群中腰痛的患病率及其与能力、表现和社会人口学变量的关联。
采用2015年智利人口调查数据进行横断面研究。选取17岁以上人群进行分析（n = 12265人）。所选变量包括：是否存在腰痛、在智利的居住地点、性别、年龄、婚姻状况、教育程度、收入、工作状态和家庭类型。通过残疾模式调查评估能力和表现水平。通过均值或频率呈现人口特征、表现和能力值。采用对数链接和伽马分布的广义线性模型来评估解释变量与结果之间的关联，同时考虑变量的分布，并对所有研究变量进行调整。
22%的人群报告有腰痛。腰痛患者的能力和表现水平较差。女性、年龄较大、教育水平较差以及健康分类较差，是与腰痛患者能力和表现较差相关的因素。相反，在过去一周有工作与该组能力的改善相关。
腰痛患者表现出较差的能力和表现结果，社会人口学变量影响他们的功能。
