To examine the association between skin tone discrimination and lifetime suicidal ideation and suicide attempt among Black Americans.
We analyzed the National Survey of American Life (NSAL), which is a national probability sample of Black American adults residing in the general population of the United States. Using multivariable logistic regression, we examined the associations between skin tone discrimination (from Blacks and from whites) and suicidal ideation and suicide attempt, adjusting for sociodemographic characteristics.
While respondents on average reported higher frequency of inter-group skin tone discrimination, only intra-group skin tone discrimination was significantly associated with greater odds of lifetime suicidal ideation [aOR: 1.21; 95% CI: 1.08-1.36] and suicide attempt [aOR: 1.22; 95% CI: 1.22; 95% CI: 1.04-1.44] adjusting for sociodemographic characteristics. Inter-group skin tone discrimination was not significantly related to suicidal ideation or suicide attempt. When stratifying by ethnicity, the effect of intra-group skin tone discrimination on suicidal ideation and attempt was stronger among Caribbean Black Americans than it was for African Americans.
All measures in the sample were self-reported and thus vulnerable to recall bias.
Intra-group skin tone discrimination is a risk factor for suicidal ideation among Black Americans, and especially among Caribbean Black Americans.
研究黑人群体中肤色歧视与终身自杀意念和自杀企图之间的关联。
我们分析了美国生活全国调查（NSAL），这是一项针对居住在美国普通人群中的美国黑人成年人的全国概率抽样调查。我们使用多变量逻辑回归，在调整了社会人口特征后，考察了来自黑人内部和白人内部的肤色歧视与自杀意念和自杀企图之间的关联。
尽管受访者平均报告了更高频率的群体间肤色歧视，但只有群体内肤色歧视与更高的终身自杀意念发生几率显著相关（aOR：1.21；95% CI：1.08-1.36）和自杀企图（aOR：1.22；95% CI：1.22；95% CI：1.04-1.44），调整了社会人口特征。群体间肤色歧视与自杀意念或自杀企图没有显著关系。当按族裔分层时，群体内肤色歧视对自杀意念和企图的影响在加勒比裔黑人中比在非裔美国人中更强。
样本中的所有措施均为自我报告，因此容易受到回忆偏倚的影响。
群体内肤色歧视是黑人群体自杀意念的一个风险因素，尤其是在加勒比裔黑人群体中。
