Insufficient physical activity (PA) is a major contributing factor in the growing problem of non-communicable diseases (NCDs) in urban and rural Sub-Saharan Africa. This study aimed to determine PA and associated factors among adults in Northern Tanzania.
We analyzed secondary data from a cross-sectional serological survey nested within the Magu health and demographic sentinel surveillance population in Magu District Northwestern Tanzania. All resident adults aged 15 years and older were invited to participate in the study, and physical activity data were analyzed for 5663 participants. Data were analyzed using Stata version 13.0. We used logistic regression to obtain odds ratios and 95% confidence intervals (CI) for risk factors associated with differences in PA.
In this mainly rural population, 96% reported sufficient PA, with a higher proportion in males (97.3%) compared to females (94.8%). In males the odds of sufficient PA were lower in rural areas compared to urban areas (OR = 0.19; P < 0.001; 95% CI = 0.08-0.42), while in females the odds of sufficient PA were higher in rural areas compared to urban areas (OR = 2.27; P < 0.001; 95%CI = 1.59-3.24). Leisure-related activity was low compared to work-related and transport-related activity. Farmers had a higher odds of sufficient PA than those in professional jobs in both males (OR = 9.75; P < 0.001; 95% CI = 3.68-5.82) and females (OR = 2.83; P = 0.021; 95% CI = 1.17-6.86).
The prevalence of PA in this population was high. However, there is need for PA programs to maintain the high level of compliance during and following the transition to a more urban-based culture.
身体活动不足是撒哈拉以南非洲城乡地区非传染性疾病（NCDs）问题日益严重的一个主要促成因素。本研究旨在确定坦桑尼亚北部成年人的身体活动及相关因素。
我们分析了坦桑尼亚西北部马古区马古健康与人口监测哨点人群中一项横断面血清学调查的二手数据。邀请所有15岁及以上的常住成年人参与研究，并对5663名参与者的身体活动数据进行了分析。数据使用Stata 13.0版本进行分析。我们使用逻辑回归来获得与身体活动差异相关的危险因素的比值比和95%置信区间（CI）。
在这个主要为农村人口的群体中，96%的人报告有充足的身体活动，男性（97.3%）的比例高于女性（94.8%）。在男性中，农村地区充足身体活动的几率低于城市地区（OR = 0.19；P < 0.001；95% CI = 0.08 - 0.42），而在女性中，农村地区充足身体活动的几率高于城市地区（OR = 2.27；P < 0.001；95%CI = 1.59 - 3.24）。与工作相关和交通相关的活动相比，休闲相关活动较少。在男性（OR = 9.75；P < 0.001；95% CI = 3.68 - 5.82）和女性（OR = 2.83；P = 0.021；95% CI = 1.17 - 6.86）中，农民充足身体活动的几率均高于从事专业工作的人。
该人群中身体活动的患病率较高。然而，需要开展身体活动项目，以便在向更加城市化的文化转变期间及之后保持较高的依从水平。
