Background

We examined area-level (aSES) and individual-level (iSES) socio-economic status on trajectories of HRQoL to 10 years following stroke.

Methods

Participants with strokes between 1/5/1996 and 30/4/1999 completed the Assessment of Quality of Life instrument (AQoL, range: -0.04 [worse than death] to 0 [death] to 1 [full health]) at ≥one of 3month, 6-month, 1-year, 2-year, 3-year, 4-year, 5-year, 7-year and 10-year interviews after stroke. Sociodemographic and health information were collected at baseline. We derived aSES from postcode using the Australian Socio-Economic Indexes For Area (2006) (categories: high, medium, low), and iSES from lifetime occupation (categories: non-manual, manual). Multivariable linear mixed effects modelling was used to estimate trajectories of HRQoL over 10 years, by aSES and iSES, adjusting for age, sex, cardiovascular disease, smoking, diabetes, stroke severity, stroke type, and the time influence on age and health conditions.

Results

Of 1,686 participants enrolled, we excluded 239 with ‘possible’ stroke and 284 with missing iSES. Among the remaining 1,163 participants, 1,123 (96.6%) had AQoL assessed at ≥3 timepoints. In multivariable analysis, over time, people in the medium aSES group had mean 0.02 (95% CI -0.06, 0.02) greater reduction in AQoL score, and people in the low aSES group had mean 0.04 (95% CI, -0.07, -0.001) greater reduction, than those in the high aSES group. Manual workers had an average 0.04 (95% CI, -0.07, -0.01) greater reduction in AQoL score over time than non-manual workers.

Conclusions

Over time, HRQoL declines in all people with stroke, declining most rapidly in lower SES groups.

与健康相关的生活质量轨迹的区域层面和个人层面的社会经济差异:一项为期 10 年的纵向卒中研究的结果

背景

我们检查了区域水平 (aSES) 和个人水平 (iSES) 社会经济状况对中风后 10 年 HRQoL 轨迹的影响。

方法

1996 年 1 月 5 日至 1999 年 4 月 30 日之间患有中风的参与者完成了生活质量评估工具(AQoL,范围:-0.04 [比死亡更糟] 至 0 [死亡] 至 1 [完全健康])≥1中风后 3 个月、6 个月、1 年、2 年、3 年、4 年、5 年、7 年和 10 年的采访。在基线收集社会人口和健康信息。我们使用 Australian Socio-Economic Indexes For Area (2006)(类别:高、中、低)从邮政编码中得出 aSES,并从终生职业中得出 iSES(类别:非体力、体力)。通过 aSES 和 iSES,使用多变量线性混合效应模型估计 HRQoL 超过 10 年的轨迹,调整年龄、性别、心血管疾病、吸烟、糖尿病、中风严重程度、中风类型以及时间对年龄和健康状况的影响。

结果

在登记的 1,686 名参与者中,我们排除了 239 名“可能”中风和 284 名缺失 iSES。在其余 1,163 名参与者中,1,123 名 (96.6%) 的 AQoL 在≥3 个时间点进行了评估。在多变量分析中,随着时间的推移,中等 aSES 组的人 AQoL 评分平均降低 0.02(95% CI -0.06,0.02),而低 aSES 组的人平均降低 0.04(95% CI,-0.07,- 0.001) 比高 aSES 组减少更多。随着时间的推移,与非体力劳动者相比,体力劳动者的 AQoL 分数平均降低 0.04(95% CI,-0.07,-0.01)。

结论

随着时间的推移,所有中风患者的 HRQoL 都在下降,在社会经济地位较低的人群中下降最快。
