Based on 20 years experiences of follow-up of the Turkish Adult Risk Factor (TARF) study, this review summarizes the distribution of risk factors among Turks which is dominated by components of the metabolic syndrome (MetS), especially abdominal obesity and atherogenic dyslipidemia. The adoption of a 95 cm cutoff for male abdominal circumference was crucial in the understanding of cardiometabolic risk factors. The prevalence of MetS, type-2 diabetes and coronary heart disease (CHD) are high, alike in Iranians. The TARF study demonstrated that low-grade systemic inflammation and oxidative stress are major determinants of cardiometabolic risk in the population at large, and involves the female sex to a greater extent than the male. As a result, impaired anti-inflammatory and atheroprotective function developed in middle-aged and elderly obese individuals emerging as dysfunction of apolipoprotein A-I and HDL particles. This dysfunction is currently a major driver cardiometabolic risk in Turkish adults leading to substantial excess diabetes and CHD. Separate algorithms for diabetes and CHD were derived that improved the risk prediction of these diseases.The author strongly suspects that such dynamics in the development of diabetes and CHD exist in Western adults prone to impaired glucose tolerance, and evidence is accumulating regarding general Iranian adults. These issues posing a vast threat on public cardiometabolic health will have to be recognized with the purpose of not delaying implementation of measures for the modification of cardiometabolic risk, especially in women.
基于土耳其成人风险因素(TARF)研究20年的随访经验,本综述总结了土耳其人群中风险因素的分布情况,其中代谢综合征(MetS)的组成部分占主导,尤其是腹型肥胖和致动脉粥样硬化性血脂异常。采用95厘米的男性腹围临界值对于理解心脏代谢风险因素至关重要。MetS、2型糖尿病和冠心病(CHD)的患病率都很高,与伊朗人相似。TARF研究表明,低度全身炎症和氧化应激是总体人群心脏代谢风险的主要决定因素,且在女性中比男性更为显著。结果,中年和老年肥胖个体出现抗炎和抗动脉粥样硬化功能受损,表现为载脂蛋白A-I和高密度脂蛋白颗粒功能障碍。这种功能障碍目前是土耳其成年人心脏代谢风险的主要驱动因素,导致糖尿病和冠心病大量增加。得出了针对糖尿病和冠心病的单独算法,改善了对这些疾病的风险预测。作者强烈怀疑,在葡萄糖耐量受损的西方成年人中,糖尿病和冠心病的发展也存在这种动态变化,而且关于伊朗普通成年人的证据也在不断积累。这些对公众心脏代谢健康构成巨大威胁的问题必须得到认识,以免延误采取措施改变心脏代谢风险,尤其是在女性中。
