目的评估西班牙65岁以上人群中高血压的患病率和发病率，并进行13年的随访。这是首次在65岁或以上的地中海人群中提供年龄调整和性别调整的高血压发病率的研究。方法以西班牙莱甘内斯市为基础的人口纵向研究。高血压的横断面患病率是使用1993、1995、1999和2006年队列中可获得的数据来估计的。522名非高血压人群的发病密度(高血压发病例数/人-年)按基线计算。结果高血压患病率随时间递增，从1993年的53.5%上升到2006年的86.2%。在所有四波中，女性的高血压患病率高于男性(P<；0.05)。高血压总发病密度为7.6[95%可信区间(CI)6.6~8.7]例/百人年，女性9.0例(95%CI 7.2~11.2)，男性6.9例(95%CI 5.8~8.3)。在所有年龄段中，女性的发病率密度均高于男性(P>；0.05)。结论65岁以上人群高血压的发病率和患病率均较高，且患病率随着时间的推移而显著增加，尤其是女性。J Hyperten 29：1863-1870(C)2011年沃尔特斯·克鲁沃健康垂直酒吧Lippincott Williams&Wilkins。
Objective To estimate the prevalence and incidence of hypertension in a Spanish cohort of people aged at least 65 years with 13 years' follow-up. This is the first study to provide age-adjusted and sex-adjusted incidence rates of hypertension in a Mediterranean-based population aged 65 years or older.Methods Population-based longitudinal study set in the city of Leganes, Spain. The cross-sectional prevalence of hypertension was estimated using data available for the 1993, 1995, 1999, and 2006 cohorts. The incidence density ( incident cases of hypertension/person-years) was calculated for 522 individuals without hypertension at baseline. Individuals were classified as hypertensive if they were taking physician-prescribed medication for hypertension or if their blood pressure was equal to or greater than 140/90 mmHg.Results Hypertension prevalence increased progressively with time, from 53.5% in 1993 to 86.2% in 2006. In all four waves, women had a higher prevalence of hypertension than men (P < 0.05). The total incidence density of hypertension was 7.6 [95% confidence interval (CI) 6.6-8.7] cases per 100 person-years of follow-up: 9.0 (95% CI 7.2-11.2) in women and 6.9 (95% CI 5.8-8.3) in men. In all age groups, the incidence density was nonsignificantly higher in women than in men (P > 0.05).Conclusion Both the incidence and prevalence of hypertension in this population of people aged at least 65 years were high, and the prevalence increased dramatically over time, especially among women.
