The aim of the present study was to assess the association between levels of physical activity (PA) and the presence of cataracts in people aged 15-69 years residing in Spain.
Cross-sectional data from the Spanish National Health Survey 2017 were analysed (n = 17,777 ≥ 15 years; 52% females; self-weighting sample). The International Physical Activity Questionnaire (IPAQ) short form was used to measure PA. Total PA MET-minutes/week were calculated, and participants were divided into two categories: 1) Less than 600 MET-minutes/week. 2) At least 600 MET-minutes/week, equivalent to meeting current PA recommendations. Cataracts were self-reported in response to the question "Have you ever been diagnosed with cataracts?". Multivariable logistic regression was used to assess associations overall and by age groups (15-49, 50-64, and 65-69 years; 15-49 and 50-69 years). Covariates included in the analysis were sex, education, BMI (Body Mass Index), multimorbidity, smoking, and alcohol consumption.
The overall prevalence of cataract was 3.7%, and the overall prevalence of participating in less than 600 MET-minutes/week of PA was 30.2%. In the adjusted overall analysis, less than 600 MET-minutes/week of PA was associated with significantly higher odds for cataract: OR = 1.324 (95% CI = 1.116-1.571). Age-stratified analyses showed that the association between PA and cataract was significant only in the age groups of 65-69 years and 50-69 years.
A significant association between PA and cataract was observed in people aged 15-69 years residing in Spain. Considering the impact on health and quality of life due to reduced PA in people with cataract, at least 600 MET-minutes/week activity should be promoted.
本研究旨在评估西班牙 15-69 岁人群的体力活动（PA）水平与白内障之间的关系。
对 2017 年西班牙国家健康调查的横断面数据进行分析（n=17777 岁；52%为女性；自我加权样本）。使用国际体力活动问卷（IPAQ）短表测量 PA。计算总 PA MET 分钟/周，参与者分为两组：1）少于 600 MET 分钟/周。2）每周至少 600 MET 分钟，相当于达到当前 PA 建议量。白内障通过回答“您是否曾被诊断患有白内障？”自我报告。多变量逻辑回归用于评估总体和年龄组（15-49、50-64 和 65-69 岁；15-49 和 50-69 岁）之间的关联。分析中包括的协变量有性别、教育程度、BMI（体重指数）、多种疾病、吸烟和饮酒。
白内障的总体患病率为 3.7%，每周进行少于 600 MET 分钟 PA 的总体患病率为 30.2%。在调整后的总体分析中，每周进行少于 600 MET 分钟的 PA 与白内障的发生几率显著增加相关：OR=1.324（95%CI=1.116-1.571）。按年龄分层分析显示，PA 与白内障之间的关联仅在 65-69 岁和 50-69 岁年龄组中具有统计学意义。
在西班牙 15-69 岁人群中，PA 与白内障之间存在显著关联。考虑到白内障患者因活动量减少对健康和生活质量的影响，应至少促进 600 MET 分钟/周的活动量。
