Awareness, Treatment, and Control of Diabetes in Bangladesh: A Nationwide Population-Based Study

ObjectivesTo examine awareness, treatment, and control of diabetes mellitus among the adult population in Bangladesh.MethodsThe study used data from the 2011 nationally representative Bangladesh Demographic and Health Survey (BDHS). The BDHS sample is comprised of 7,786 adults aged 35 years or older. The primary outcome variables were fasting blood glucose, diagnosis, treatment, and control of diabetes. Multilevel logistic regression models were used to identify the risk factors for diabetes awareness.ResultsOverall, age-standardized prevalence of diabetes was 9.2%. Among subjects with diabetes, 41.2% were aware of their condition, 36.9% were treated, and 14.2% controlled their condition. A significant inequality in diabetes management was found from poor to wealthy households: 18.2% to 63.2% (awareness), 15.8% to 56.6% (treatment), and 8.2% to 18.4% (control). Multilevel models suggested that participants who had a lower education and lower economic condition were less likely to be aware of their diabetes. Poor management was observed among non-educated, low-income groups, and those who lived in the northwestern region.ConclusionsDiabetes has become a national health concern in Bangladesh; however, treatment and control are quite low. Improving detection, awareness, and treatment strategies is urgently needed to prevent the growing burden associated with diabetes.研究目标 本研究旨在探讨孟加拉国成年人群中糖尿病（diabetes mellitus）的知晓率、治疗现状与疾病控制水平。研究方法 本研究采用2011年具有全国代表性的孟加拉国人口与健康调查（BDHS）数据。该调查共纳入7786名35岁及以上的成年研究对象。本研究的主要结局指标包括空腹血糖水平、糖尿病诊断情况、治疗情况与疾病控制水平，采用多水平logistic回归模型分析糖尿病知晓率的相关危险因素。研究结果 总体而言，经年龄标化的糖尿病患病率为9.2%。在确诊糖尿病的研究对象中，41.2%知晓自身患病情况，36.9%接受了规范治疗，14.2%实现了病情控制。不同经济阶层的糖尿病管理存在显著梯度差异：从低收入家庭到高收入家庭，糖尿病知晓率从18.2%升至63.2%，治疗率从15.8%升至56.6%，控制率从8.2%升至18.4%。多水平模型分析结果显示，受教育程度较低、经济状况较差的研究对象，知晓自身罹患糖尿病的概率显著更低。未接受教育、低收入群体以及居住在该国西北部地区的人群，糖尿病管理状况普遍较差。研究结论 目前糖尿病已成为孟加拉国亟待重视的国民健康问题，但其治疗与控制水平仍相对低下。亟需优化糖尿病筛查、健康宣教与治疗策略，以遏制糖尿病相关疾病负担的持续增长。
