Prediction of 10-year risk for ischemic cardiovascular disease in adults aged 35 years old and above in Nanjing
-
摘要:
目的 了解南京市≥35岁人群缺血性心血管病(ischemia cardiovascular disease, ICVD)10年发病风险。 方法 采用多阶段分层整群抽样方法,随机抽取南京市≥18岁常住居民61 098名作为调查对象。最终纳入年龄≥35岁且无ICVD病史36 079名作为研究对象。采用《国人ICVD 10年发病风险评估表》评估ICVD发病风险。 结果 研究对象平均年龄(53.8±11.7)岁,其中男性17 681名,占比49.0%,女性18 398名,占比51.0%。人群ICVD 10年发病风险总得分为(5.1±3.7)分,绝对危险度为2.1%(0.8%~5.4%);其中发病风险≥10%比例为12.6%,女性高于男性(15.0% vs 10.1%),且随着年龄的增加而增长,差异均有统计学意义(均有P < 0.001)。ICDV危险因素≥3的人群比例为23.0%,男性高于女性(31.8% vs 14.6%),差异有统计学意义(χ2=1 509.07, P < 0.001)。男女各危险因素评分在总危险因素评分权重最高分别为吸烟(34.8%)和体重异常(32.5%)。 结论 南京市≥35岁人群ICVD 10年发病风险高危人群比例已超过10%。需重点关注老年人、体重异常者、高血压者。男性应加强烟草控制,女性应加强体重管理。 Abstract:Objective To understand the exposure of risk factors related to Ischemia Cardiovascular Disease (ICVD) in a population aged ≥35 years in Nanjing and to estimate their 10-year risk of ICVD. Methods Multi-stage stratified cluster sampling method was used to randomly select 61 098 permanent residents ≥18 years of age in Nanjing. A total of 36 079 people aged ≥35 years old with no history of ICVD were selected as the study subjects. The "10-year Risk Assessment Table of ICVD in Chinese" was used to assess the risk of ICVD. Results The subjects were (53.8 ± 11.7) years old, including 17 681 men (49.0%) and 18 398 women (51.0%). The score of 10-year risk for ICVD was (5.1 ± 3.7) points, and the absolute risk was 2.1% (0.8%-5.4%); of which, the proportion of ICVD 10-year incidence risk ≥10% was 12.6%, and women were higher than men (15.0% vs 10.1%). Besides, the risk score was found increased with age, and the differences among different age groups were statistically significant (P < 0.001). The proportion of people with ICDV risk factors ≥3 was 23.0%, and the proportion of men is higher than that of women (31.8% vs 14.6%), and the difference was also statistically significant (χ2=1 509.07, P < 0.001). Among the total risk score of ICVD, smoking (34.8%) and BMI (32.5%) accounted for the highest proportion in male and female, respectively. Conclusion The risk of ICVD ≥10% in the population aged ≥35 years old in Nanjing in the next 10 years has exceeded 10%. Attention should be paid to the elderly, abnormal weight and hypertension population. Men should strengthen tobacco control, and women should strengthen weight health management. -
