Background. Hypertension and dyslipidemia are independent risk factors for coronary heart disease and commonly coexist. Cardiovascular risk can be reliably predicted using lipid ratios such as the atherogenic index, a useful prognostic parameter for guiding timely interventions. Objective. We assessed the cardiovascular risk profile based on the atherogenic index of residents within a rural Ugandan cohort. Methods. In 2011, a population based survey was conducted among 7507 participants. Sociodemographic characteristics, physical measurements (blood pressure, weight, height, and waist and hip circumference), and blood sampling for nonfasting lipid profile were collected for each participant. Atherogenic risk profile, defined as logarithm base ten of (triglyceride divided by high density lipoprotein cholesterol), was categorised as low risk (<0.1), intermediate risk (0.1-0.24), and high risk (>0.24). Results. Fifty-five percent of participants were female and the mean age was 49.9 years (SD ± 20.2). Forty-two percent of participants had high and intermediate atherogenic risk. Persons with hypertension, untreated HIV infection, abnormal glycaemia, and obesity and living in less urbanised villages were more at risk. Conclusion. A significant proportion of persons in this rural population are at risk of atherosclerosis. Key identified populations at risk should be considered for future intervention against cardiovascular related morbidity and mortality. The study however used parameters from unfasted samples that may have a bearing on observed results.
背景。高血压和血脂异常是冠心病的独立危险因素,且常同时存在。使用诸如致动脉粥样硬化指数等血脂比值可可靠地预测心血管风险,该指数是指导及时干预的有用预后参数。目的。我们基于乌干达农村队列居民的致动脉粥样硬化指数评估心血管风险状况。方法。2011年,对7507名参与者进行了一项基于人群的调查。收集了每位参与者的社会人口学特征、身体测量数据(血压、体重、身高以及腰围和臀围)以及非空腹血脂谱的血样。致动脉粥样硬化风险状况定义为(甘油三酯除以高密度脂蛋白胆固醇)的以十为底的对数,分为低风险(<0.1)、中度风险(0.1 - 0.24)和高风险(>0.24)。结果。55%的参与者为女性,平均年龄为49.9岁(标准差±20.2)。42%的参与者有致动脉粥样硬化高风险和中度风险。患有高血压、未接受治疗的艾滋病毒感染、血糖异常、肥胖以及生活在城市化程度较低村庄的人风险更高。结论。该农村人群中有很大一部分人有动脉粥样硬化风险。对于未来预防心血管相关发病和死亡的干预措施,应考虑已确定的关键高危人群。然而,该研究使用的是非空腹样本的参数,这可能对观察结果有影响。
