Southeast Asia is experiencing a health transition, where non-communicable diseases (NCD) are exceeding communicable diseases. Despite NCDs accounting for roughly 60-85% of deaths in the region, many developing Southeast Asian countries are beginning to address the impacts of a physically inactive lifestyle for the first time. Our study aims to bridge this gap by objectively measuring physical activity in rural Lao PDR to reveal the association among physical activity, activity space, and seasonal variation.
Multiple waves of survey data were collected in Songkhon District, Lao PDR between March 2010 and March 2011. Adults aged between 18 and 65 were recruited (n = 48). A portable GPS recorded participants' activity and farmland locations and an accelerometer recorded participants' physical activity level and daily steps for seven consecutive days. Using a directional distribution tool in ArcGIS 10.5, the activity space area of each participant in each wave was calculated. Concurrently, participants recorded time spent on each daytime activity. Linear mixed models with the fixed effects as the observations from different waves and the random effects as individual participants were developed to identify factors associated with areas of activity space and counts of daily steps, respectively.
A total of 48 respondents aged between 19 and 57 took part in the study. Half of the participants were females. Walking was found to be the most frequent travel mode. Females were physically less active, with a smaller activity space, and were more overweight than the males in the study. Participants were physically less active during the off-farming seasons.
Findings contribute to the surveillance of risk factors needed to create healthy living environments. Our research is also one of the first to use empirical evidence demonstrating seasonal variations of rural residents' activities in mainland Southeast Asia.
东南亚正在经历健康转型，非传染性疾病（NCD）的致死率超过了传染病。尽管该地区约60%-85%的死亡由非传染性疾病导致，但许多东南亚发展中国家才刚刚开始首次应对缺乏身体活动的生活方式所带来的影响。我们的研究旨在通过客观测量老挝农村地区的身体活动，揭示身体活动、活动空间和季节变化之间的关联，以填补这一空白。
2010年3月至2011年3月期间，在老挝的宋孔县收集了多轮调查数据。招募了年龄在18至65岁之间的成年人（n = 48）。使用便携式全球定位系统（GPS）记录参与者的活动和农田位置，并用加速度计连续七天记录参与者的身体活动水平和每日步数。利用ArcGIS 10.5中的方向分布工具，计算每一轮中每个参与者的活动空间面积。同时，参与者记录了每项白天活动所花费的时间。分别建立了以不同轮次的观测值为固定效应、以个体参与者为随机效应的线性混合模型，以确定与活动空间面积和每日步数相关的因素。
共有48名年龄在19至57岁之间的受访者参与了该研究。一半的参与者为女性。步行被发现是最常见的出行方式。在研究中，女性的身体活动较少，活动空间较小，且比男性更超重。参与者在农闲季节的身体活动较少。
研究结果有助于监测创建健康生活环境所需的风险因素。我们的研究也是首批利用实证证据证明东南亚大陆农村居民活动存在季节性变化的研究之一。
