This study examined differences in the trajectory of depressive symptoms between Hispanic, Black, and White Americans in middle and old age.
Data came from a national sample of Americans with up to 6 repeated assessments spanning 11 years. Hierarchical linear models with time-varying covariates were used.
Hispanics started with the worst depressive symptomatology, followed by Black Americans, whereas White Americans had the fewest symptoms. These differences, however, diminished over time. More importantly, net of socioeconomic and health differentials, the depressive symptoms trajectory did not differ between Blacks and Whites, whereas Hispanics still started with worse symptoms and had a greater rate of reduction in symptomatology compared to Whites.
Significant ethnic differences exist in both the intercept and rate of change in depressive symptoms in middle-aged and older Americans. These variations are substantially confounded by socioeconomic and health differentials.
本研究考察了中年和老年时期西班牙裔、非裔和美国白人在抑郁症状轨迹上的差异。
数据来自一个全国性的美国人群样本，这些人在 11 年内接受了多达 6 次重复评估。使用具有时变协变量的分层线性模型。
西班牙裔的抑郁症状最严重，其次是非裔美国人，而白人的症状最少。然而，这些差异随着时间的推移而减少。更重要的是，在排除社会经济和健康差异后，黑人和白人之间的抑郁症状轨迹没有差异，而西班牙裔的症状起始较差，且症状减轻的速度比白人更快。
在美国中年和老年人中，抑郁症状的截距和变化率存在显著的种族差异。这些差异主要受到社会经济和健康差异的影响。
