Physical activity (PA) is an important lifestyle recommendation for managing type-2 diabetes mellitus (T2DM). However, low PA among them is a global public health concern, including Bangladesh. We aimed to investigate the prevalence of low PA levels and its associated sociodemographic factors particularly among middle-aged T2DM subjects, which is quite limited globally and unknown in Bangladesh. In this cross-sectional study, we conveniently recruited 356 T2DM subjects (aged 40–60 years) from outpatient departments of the corresponding diabetic hospitals from Pirojpur and Dinajpur, the southern and northern districts, respectively. The primary outcome was low PA (via metabolic equivalents <600), using the Global Physical Activity Questionnaire. Univariable and multivariable binary logistic regression analyses were used to identify the factors associated with low PA. Among the participants (mean age 51.0±6.9 years), men and women were with almost equal proportions (48.9% and 51.1%, respectively). The prevalence (95% Confidence Intervals [CI]) of low PA was 34.8% (29.9–39.7). The median sitting or reclining time was 6 hours on a typical day. The odds (OR [95% CI]; P) of low PA was found to be significantly higher in respondents with primary or no education compared to the above-primary level, in unadjusted (1.6 [1.1–2.6]; 0.029) and adjusted (2.0 [1.1–3.7]; 0.028) associations both. In conclusion, over one-third of the middle-aged study subjects had a low PA level, which was associated with education. There is a high demand for designing and implementing PA enhancing interventions among them.

体力活动（Physical Activity, PA）是管理2型糖尿病（type-2 diabetes mellitus, T2DM）的重要生活方式干预建议。然而，该人群体力活动水平低下是一项全球性公共卫生议题，孟加拉国亦存在此类问题。本研究旨在探讨中年2型糖尿病患者体力活动低下的患病率及其相关社会人口学因素，目前全球范围内此类研究较为匮乏，孟加拉国更是尚无相关报道。本项横断面研究采用便利抽样法，从分别位于南部皮罗杰布尔（Pirojpur）和北部迪纳杰布尔（Dinajpur）的两所糖尿病医院的门诊科室招募了356名年龄介于40~60岁的2型糖尿病研究对象。本研究的主要结局为体力活动低下，以代谢当量（metabolic equivalents）<600为判定标准，采用全球体力活动问卷（Global Physical Activity Questionnaire）进行评估。本研究采用单变量及多变量二元logistic回归分析，筛选与体力活动低下相关的影响因素。本研究对象平均年龄为51.0±6.9岁，男女占比近乎均等，分别为48.9%和51.1%。该人群体力活动低下的患病率为34.8%（95%置信区间[Confidence Intervals, CI]：29.9~39.7）。研究对象的中位每日久坐或躺卧时长为6小时。与受教育程度高于小学水平的研究对象相比，仅接受小学及以下教育或未接受过教育的研究对象，其体力活动低下的比值比（Odds Ratio, OR [95% CI]; P值）显著升高；未校正模型中OR为1.6（95%CI：1.1~2.6；P=0.029），校正模型中OR为2.0（95%CI：1.1~3.7；P=0.028），两者均具有统计学意义。综上，本研究中超过三分之一的中年研究对象存在体力活动水平低下的情况，且该情况与受教育程度显著相关。针对该人群设计并实施提升体力活动水平的干预措施具有极高的必要性。
