Regular physical activity may be an important contributor to psychological well-being. This link has not been explored in ethnically distinct, low- and middle-income countries (LMIC), especially in countries affected by war. This study aimed to examine the relationship between physical activity and levels of psychological distress in an epidemiological cross-representative sample of Vietnamese living in the Mekong Delta region of Vietnam.
The sample was drawn from an urban (Cn Th City) and a rural (H u Giang) region, using a multi-stage probabilistic cluster sampling frame. The measures applied included the Composite International Diagnostic Interview (CIDI 2.0) yielding 12-month prevalence rates of common mental disorders, including anxiety, mood and substance use disorders; the Phan Vietnamese Psychiatric Scale (PVPS), a culturally specific self-report measure; and the Harvard Trauma Questionnaire. The Global Physical Activity Questionnaire (GPAQ version 1) was used to measure activity. Analyses were conducted using SAS software v.9.1.3. The population was assigned to three (high, moderate and low) physical activity levels. Analyses included chi-square tests and univariable and multivariable logistic models.
Physical activity was greater in males, the middle-aged group (30-54 years), those who were married, the rural population, less educated individuals and those who were employed. High physical activity was significantly associated with low levels of psychological distress (indexed by a combination of CIDI and PVPS cases identified) when controlling for socio-demographic factors and number of medical conditions). Membership of the lowest of the three physical activity groups was associated with a psychological distress odds ratio of 2.19 (95% CI 1.28-3.75). The results remained consistent when analyses were undertaken separately for males and females.
Low levels of physical activity appear to be associated with greater psychological distress in the Mekong Delta of Vietnam. The association remained after adjusting for the influence of socio-demographic characteristics, exposure to past trauma, urban-rural residency and the presence of self-reported physical disorders. These data provide a foundation for exploring the role of physical activity as an adjunct to conventional interventions for common mental disorders in resource-poor LMIC countries.
有规律的身体活动可能是心理幸福感的一个重要贡献因素。这一联系在种族不同、中低收入国家（LMIC），特别是在受战争影响的国家，尚未得到探索。本研究旨在调查越南湄公河三角洲地区居住的越南人代表性横断面样本中身体活动与心理困扰水平之间的关系。
该样本来自城市（芹苴市）和农村（坚江省）地区，采用多阶段概率聚类抽样框架。应用的措施包括使用复合国际诊断访谈（CIDI 2.0）得出包括焦虑、情绪和物质使用障碍在内的常见精神障碍的 12 个月患病率；使用文化特异性自我报告措施 Phan 越南精神病量表（PVPS）；以及哈佛创伤问卷。全球体力活动问卷（GPAQ 版本 1）用于测量活动。使用 SAS 软件 v.9.1.3 进行分析。人群被分配到三个（高、中、低）体力活动水平。分析包括卡方检验和单变量和多变量逻辑模型。
男性、中年组（30-54 岁）、已婚人士、农村人口、受教育程度较低的个体和就业者的体力活动水平较高。在控制社会人口因素和医疗条件数量后，高体力活动与低心理困扰水平（通过 CIDI 和 PVPS 确定的病例综合指数）显著相关。在三个体力活动组中，最低组的心理困扰比值比为 2.19（95%CI 1.28-3.75）。当对男性和女性分别进行分析时，结果仍然一致。
在越南湄公河三角洲地区，低水平的体力活动似乎与更大的心理困扰有关。在调整社会人口特征、过去创伤暴露、城乡居住和自我报告身体障碍的影响后，这种关联仍然存在。这些数据为探索身体活动作为资源匮乏的中低收入国家常见精神障碍常规干预的辅助手段的作用提供了基础。
