Physical inactivity is a leading risk factor for cardiovascular and other noncommunicable diseases in high-, low- and middle-income countries. Nepal, a low-income country in South Asia, is undergoing an epidemiological transition. Although the reported national prevalence of physical inactivity is relatively low, studies in urban and peri-urban localities have always shown higher prevalence. Therefore, this study aimed to measure physical activity in three domains-work, travel and leisure-in a peri-urban community and assess its variations across different sociodemographic correlates.
Adult participants (n=640) from six randomly selected wards of the Jhaukhel-Duwakot Health Demographic Surveillance Site (JD-HDSS) near Kathmandu responded to the Global Physical Activity Questionnaire. To determine total physical activity, we calculated the metabolic equivalent of task in minutes/week for each domain and combined the results. Respondents were categorized into high, moderate or low physical activity. We also calculated the odds ratio for low physical activity in various sociodemographic variables and self-reported cardiometabolic states.
The urbanizing JD-HDSS community showed a high prevalence of low physical activity (43.3%; 95% CI 39.4-47.1). Work-related activity contributed most to total physical activity. Furthermore, women and housewives and older, more educated and self-or government-employed respondents showed a greater prevalence of physical inactivity. Respondents with hypertension, diabetes or overweight/obesity reported less physical activity than individuals without those conditions. Only 5% of respondents identified physical inactivity as a cardiovascular risk factor.
Our findings reveal a high burden of physical inactivity in a peri-urban community of Nepal. Improving the level of physical activity involves sensitizing people to its importance through appropriate multi-sector strategies that provide encouragement across all sociodemographic groups.
身体活动不足是高、中、低收入国家心血管疾病和其他非传染性疾病的主要危险因素。尼泊尔是南亚的一个低收入国家，正在经历一场流行病学转变。尽管报告的全国身体活动不足的流行率相对较低，但在城市和城郊地区进行的研究始终显示出更高的流行率。因此，本研究旨在测量城郊社区中工作、旅行和休闲三个领域的身体活动，并评估其在不同社会人口学相关因素中的差异。
来自加德满都附近的Jhaukhel-Duwakot 健康人口监测点（JD-HDSS）六个随机选择的区的成年参与者（n=640）回答了全球身体活动问卷。为了确定总身体活动量，我们计算了每个领域的任务代谢当量分钟/周，并将结果合并。受访者被分为高、中或低身体活动水平。我们还计算了各种社会人口学变量和自我报告的心血管代谢状态下低身体活动的比值比。
城市化的 JD-HDSS 社区显示出高比例的低身体活动（43.3%；95%CI 39.4-47.1）。与工作相关的活动对总身体活动的贡献最大。此外，女性和家庭主妇以及年龄较大、教育程度较高、自我或政府就业的受访者表现出更高的身体活动不足发生率。患有高血压、糖尿病或超重/肥胖的受访者比没有这些疾病的人报告的身体活动量更少。只有 5%的受访者认为身体活动不足是心血管风险因素。
我们的研究结果显示，尼泊尔城郊社区的身体活动不足负担很重。通过提供跨所有社会人口学群体的鼓励的适当多部门策略，提高身体活动水平需要使人们意识到其重要性。
