With the increasing burden of non-communicable diseases in low-income and middle-income countries, biological risk factors, such as hyperglycaemia, are a major public health concern in Bangladesh. Hyperglycaemia is an excess of glucose in the bloodstream and is often associated with type 2 diabetes mellitus. Nationally representative data of hyperglycaemia prevalence starting from age ≥18 years are currently unavailable for Bangladeshi adults. The objective of this study was to assess the prevalence and determinants of hyperglycaemia among adults in Bangladesh aged ≥18 years.
Cross-sectional, population-based study.
Data for this analysis were collected in November to December 2015, from a population-based nationally representative sample of 1843 adults, aged ≥18 years, from both urban and rural areas of Bangladesh. Demographic information, capillary blood glucose, blood pressure, height, weight, waist circumference and treatment history were recorded.
Hyperglycaemia was defined as a random capillary blood glucose level of ≥11.1 mmol/L (ie, in the diabetic range) or currently taking medication to control type 2 diabetes, based on self-report.
Overall, the prevalence of hyperglycaemia was 5.5% (95% CI 4.5% to 6.6%) and was significantly higher among urban (9.8%, 95% CI 7.7% to 12.2%) than rural residents (2.8%, 95% CI 1.9% to 3.9%). The age-standardised prevalence of hyperglycaemia was 5.6% (95% CI 4.6% to 6.8%). Among both urban and rural residents, the associated determinants of hyperglycaemia included hypertension and abdominal obesity. About 5% of the total population self-reported have been previously diagnosed with type 2 diabetes; among these adults, over 25% were not taking medications to control their diabetes.
Our study found that about 1 in 20 Bangladeshi adults aged ≥18 years have hyperglycaemia. To control and prevent the development of type 2 diabetes, data from this study can be used to inform public health programming and provide descriptive information on surveillance of progress towards controlling diabetes in Bangladesh.
随着低收入和中等收入国家非传染性疾病负担的增加，高血糖等生物危险因素成为孟加拉国的一个主要公共卫生关注点。高血糖是指血液中葡萄糖含量过高，通常与 2 型糖尿病有关。目前，孟加拉国成年人还没有年龄在 18 岁及以上的全国代表性高血糖患病率数据。本研究旨在评估孟加拉国年龄在 18 岁及以上成年人的高血糖患病率及其决定因素。
横断面、基于人群的研究。
本分析的数据于 2015 年 11 月至 12 月期间采集自孟加拉国城乡地区一个基于人群的全国代表性样本，该样本包括 1843 名年龄在 18 岁及以上的成年人。记录了人口统计学信息、毛细血管血糖、血压、身高、体重、腰围和治疗史。
高血糖定义为随机毛细血管血糖水平≥11.1mmol/L（即糖尿病范围）或根据自我报告目前正在服用药物控制 2 型糖尿病。
总体而言，高血糖的患病率为 5.5%（95%CI：4.5%至 6.6%），城市居民（9.8%，95%CI：7.7%至 12.2%）显著高于农村居民（2.8%，95%CI：1.9%至 3.9%）。高血糖的年龄标准化患病率为 5.6%（95%CI：4.6%至 6.8%）。在城市和农村居民中，高血压和腹型肥胖是高血糖的相关决定因素。大约 5%的总人口自我报告曾被诊断患有 2 型糖尿病；在这些成年人中，超过 25%的人没有服用药物来控制他们的糖尿病。
我们的研究发现，约 1/20 的孟加拉国年龄在 18 岁及以上的成年人患有高血糖。为了控制和预防 2 型糖尿病的发生，本研究的数据可用于为公共卫生规划提供信息，并提供孟加拉国控制糖尿病进展监测的描述性信息。
