Considering that physical activity is associated with healthy ageing and helps to delay, prevent, or manage a plethora of non-communicable diseases in older adults, there is a need to investigate the factors that influence physical activity participation in this population. Thus, we investigated physical activity correlates among community-dwelling older adults (aged ≥50 years) in six low- and middle-income countries.
Cross-sectional data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health. Physical activity was assessed by the Global Physical Activity Questionnaire. Participants were dichotomized into low (i.e., not meeting 150 minutes of moderate physical activity per week) and moderate-to-high physically active groups. Associations between physical activity and a range of correlates were examined using multivariable logistic regressions.
The overall prevalence (95%CI) of people not meeting recommended physical activity levels in 34,129 participants (mean age 62.4 years, 52.1% female) was 23.5% (22.3%-24.8%). In the multivariable analysis, older age and unemployment were significant sociodemographic correlates of low physical activity. Individuals with low body mass index (<18.5kg/m2), bodily pain, asthma, chronic back pain, chronic obstructive pulmonary disease, hearing problems, stroke, visual impairment, slow gait, and weak grip strength were less likely to meet physical activity targets in the overall sample (P<0.05). The associations varied widely between countries.
Our data illustrates that a multitude of factors influence physical activity target achievement in older adults, which can inform future interventions across low- and middle-income countries to assist people of this age group to engage in regular physical activity. Future prospective cohort studies are also required to investigate the directionality and mediators of the relationships observed.
鉴于身体活动与健康老龄化相关，并有助于延缓、预防或管理老年人的多种非传染性疾病，有必要调查影响该人群参与身体活动的因素。因此，我们调查了六个低收入和中等收入国家社区居住的老年人（年龄≥50岁）中与身体活动相关的因素。
分析了世界卫生组织全球老龄化与成人健康研究的横断面数据。通过全球身体活动问卷评估身体活动。参与者被分为低身体活动组（即每周中度身体活动不足150分钟）和中度至高度身体活动组。使用多变量逻辑回归分析身体活动与一系列相关因素之间的关联。
34129名参与者（平均年龄62.4岁，52.1%为女性）中未达到推荐身体活动水平的总体患病率（95%CI）为23.5%（22.3%-24.8%）。在多变量分析中，年龄较大和失业是低身体活动的重要社会人口学相关因素。体重指数低（<18.5kg/m2）、身体疼痛、哮喘、慢性背痛、慢性阻塞性肺疾病、听力问题、中风、视力障碍、步态缓慢和握力弱的个体在总体样本中达到身体活动目标的可能性较小（P<0.05）。各国之间的关联差异很大。
我们的数据表明，多种因素影响老年人身体活动目标的实现，这可为未来低收入和中等收入国家的干预措施提供参考，以帮助该年龄组的人进行定期身体活动。还需要未来的前瞻性队列研究来调查所观察到的关系的方向性和中介因素。
