Control of blood pressure is important in old age for prevention of hypertension-associated complications. This study aimed to investigate the factors associated with control of hypertension in elderly people (>or=60 years old) diagnosed with hypertension.
The subjects were those who had a self-reported diagnosis of hypertension (532 men and 1078 women) from a stratified random cluster sample of 4201 people aged 60 years or older. Controlled hypertension was defined as a systolic blood pressure (SBP) <140 mmHg and diastolic blood pressure (DBP) <90 mmHg, and SBP <130 mmHg and DBP <80 mmHg for subjects with diabetes.
The prevalence of controlled hypertension (25.9%) was low. In older women, the prevalence of isolated uncontrolled SBP was increased. After adjusting for other covariates, uncontrolled hypertension was positively associated with body mass index (BMI>or=23 kg/m(2)), and negatively associated with balanced diet and a past history of cardiovascular disease in men, whereas in women it was positively associated with waist circumference (>or=80 cm).
In elderly people diagnosed with hypertension general obesity (high BMI) appears to have an important influence on uncontrolled hypertension in men, whereas abdominal obesity (high waist circumference) appears to be an important factor in women.
控制血压对于老年人预防高血压相关并发症至关重要。本研究旨在调查确诊为高血压的老年人（≥60岁）中与高血压控制相关的因素。
研究对象为来自4201名60岁及以上人群的分层随机整群样本中自我报告诊断为高血压的患者（532名男性和1078名女性）。血压得到控制的高血压定义为收缩压（SBP）<140 mmHg且舒张压（DBP）<90 mmHg，对于糖尿病患者，收缩压<130 mmHg且舒张压<80 mmHg。
血压得到控制的高血压患病率（25.9%）较低。在老年女性中，单纯收缩压未得到控制的患病率有所增加。在对其他协变量进行调整后，未得到控制的高血压与体重指数（BMI≥23 kg/m²）呈正相关，在男性中与均衡饮食和心血管疾病既往史呈负相关，而在女性中与腰围（≥80 cm）呈正相关。
在确诊为高血压的老年人中，总体肥胖（高BMI）似乎对男性未得到控制的高血压有重要影响，而腹型肥胖（高腰围）似乎是女性的一个重要因素。
