To analyze prospectively the association between hormone replacement therapy (HRT) and mortality in women before old age.
A group of 11,667 women (91% of the age cohort of the area) aged 52-62 years from the population-based Kuopio Osteoporosis Risk Factor and Prevention Study were followed for 7 years in 1994-2001. Information about HRT use and health events was obtained from two repeated questionnaires in 1989 and 1994. Information about deaths and causes of death from the follow-up period was obtained from the Statistics Finland. Cox's proportional-hazards models were used to calculate risk of death related to the use of HRT.
At the start of follow-up, 2203 women had used HRT > 5 years, 3945 women < or = 5 years and 5519 women had never used it. During the follow-up, 361 deaths occurred. Compared with non-users of HRT, the adjusted hazard ratio (HR) of death from any cause was 1.05 (95% confidence interval (CI) 0.80-1.36) in women who used HRT < or = 5 years and 1.06 (95% CI 0.78-1.46) in women who used HRT > 5 years. The adjusted HR for coronary heart disease (CHD) mortality in women who used HRT < or = 5 years was 0.79 (95% CI 0.36-1.73), and in women who used HRT > 5 years, 2.16 (95% CI 0.93-4.98). For breast cancer mortality the adjusted HR for < or = 5 years of HRT use was 0.96 (95% CI 0.32-2.82) and 2.62 (95% CI 0.98-7.00) for > 5 years of HRT use.
History of HRT use does not affect overall or CHD mortality in women. More than 5 years of HRT use may increase the risk of breast cancer mortality.
前瞻性分析激素替代疗法(HRT)与老年前女性死亡率之间的关联。
基于人群的库奥皮奥骨质疏松症风险因素与预防研究中,选取了11667名年龄在52 - 62岁的女性(占该地区年龄队列的91%),于1994年至2001年进行了7年的随访。关于HRT使用情况和健康事件的信息来自1989年和1994年的两份重复问卷。随访期间的死亡及死因信息来自芬兰统计局。采用Cox比例风险模型计算与使用HRT相关的死亡风险。
随访开始时,2203名女性使用HRT超过5年,3945名女性使用HRT≤5年,5519名女性从未使用过HRT。随访期间,共发生361例死亡。与未使用HRT的女性相比,使用HRT≤5年的女性任何原因导致的死亡调整风险比(HR)为1.05(95%置信区间(CI)0.80 - 1.36),使用HRT超过5年的女性为1.06(95%CI 0.78 - 1.46)。使用HRT≤5年的女性冠心病(CHD)死亡率调整HR为0.79(95%CI 0.36 - 1.73),使用HRT超过5年的女性为2.16(95%CI 0.93 - 4.98)。对于乳腺癌死亡率,使用HRT≤5年的调整HR为0.96(95%CI 0.32 - 2.82),使用HRT超过5年的为2.62(95%CI 0.98 - 7.00)。
HRT使用史不影响女性的总体死亡率或CHD死亡率。使用HRT超过5年可能会增加乳腺癌死亡风险。
