这项研究的目的是在一项基于人群的队列研究中，与其他定义不明确的疾病(定义不明确的心血管疾病、癌症和伤害)进行比较，以检验症状、体征和定义不明确的条件下死亡的时间趋势和预测因素的差异。在1606名年龄在60岁及以上的基线参与者中，524人在9年的随访中死亡，并纳入了这项研究。从1997-1999年到2003-2005年，按“症状”编码的死亡人数下降了77%。对其他定义不清的情况进行编码的死亡人数保持不变。2003-2005年(相对危险度=0.25；95%可信区间：0.09-0.70)和住院死亡(相对危险度=0.16；95%可信区间：0.08-0.34)与“症状”独立相关，但与其他定义不清的情况无关。基线社会人口学特征和慢性病不是这些结果的预测因素。国际和国家机构把重点放在减少与“症状”有关的死亡人数上，以改进生命统计数据的登记，而其他定义不清的情况则鲜有人关注。我们的数据提供了支持纠正这种情况的必要性的证据。
The study objective was to examine differentials in time trends and predictors of deaths assigned to symptoms, signs and ill-defined conditions in comparison with other ill-defined conditions (ill-defined cardiovascular diseases, cancer and injury) in a population-based cohort study. Of 1,606 baseline participants aged 60 years and over, 524 died during 9-year follow-up and were included in this study. Deaths coded to "symptoms" declined by 77% in the period from 1997-1999 to 2003-2005. Deaths coded to other ill-defined conditions remained unchanged. The calendar period 2003-2005 (RR = 0.25; 95% CI: 0.09-0.70) and in-hospital deaths (RR = 0.16; 95% CI: 0.08-0.34) were independently associated with "symptoms", but not with other ill-defined conditions. Baseline socio-demographic characteristics and chronic diseases were not predictors of these outcomes. International and national agencies have focused on the reduction of deaths assigned to "symptoms" to improve the registration of vital statistics, while other ill-defined conditions have received little attention. Our data provide evidence supporting the need to redress this situation.
