Limited data are available on physical activity tracking among adults in low- and middle-income countries. Using a longitudinal design, we assessed trends and correlates of physical activity among Sri Lankan adults. Individuals selected through age-stratified random sampling, were screened initially in 2007 (n = 2986) and reevaluated in 2014 (n = 2148). On both occasions, structured interviews and clinical measurements were completed. Approximately 40% of the participants engaged in recommended levels of physical activity both at baseline and follow-up. One-fifth reported increased physical activity at follow-up, a similar proportion reported being persistently inactive or a reduction in physical activity. In the adjusted analysis, being persistently active was associated with male sex, a lower educational level and income, being free of any chronic disease conditions, better self-rated health, and sitting time <8 hours. Our findings support public health interventions to help maintain recommended physical activity levels over time, particularly for subgroups at high-risk of physical inactivity.
关于中低收入国家成年人的身体活动追踪，相关数据有限。本研究采用纵向设计，评估了斯里兰卡成年人的身体活动趋势及其相关因素。通过分层随机抽样选择的个体于 2007 年（n=2986）和 2014 年（n=2148）进行初次筛选和重新评估。两次评估均完成了结构化访谈和临床测量。大约 40%的参与者在基线和随访时均达到了推荐的身体活动水平。五分之一的人在随访时报告身体活动增加，同样比例的人报告持续不活动或身体活动减少。在调整分析中，持续活跃与男性、较低的教育水平和收入、无任何慢性疾病、更好的自我健康评估和坐姿时间<8 小时有关。我们的研究结果支持公共卫生干预措施，以帮助人们随着时间的推移保持推荐的身体活动水平，特别是针对身体活动不足高危人群的干预措施。
