To determine how self-esteem mediates the relationship between family support and initiation of sex for US-born Black Caribbean compared to African American adolescents. Secondary data analyses were performed on responses from 1170 adolescents from the National Survey of American Life—Adolescents supplement (2003–2004). Weighted descriptive statistics and logistic regression analyses were performed to examine whether initiation of sex on perceived family support is mediated by self-esteem. The study population consists of 360 Black Caribbean and 810 African American adolescents. Sexual initiation prevalence was higher for Black Caribbean adolescents (42.1%) than African American adolescents (36.75%). The adjusted odds ratio for Black Caribbean adolescents' initiation of sex was 0.85 (95% confidence interval [CI]: 0.16–4.51) compared to African American adolescents' 0.59 (95% CI: 0.35–1.00). Self-esteem represented a statistically significant mediation path and might be more important for African American adolescents' sexual health than the Black Caribbean. The unfounded mediating role of self-esteem between perceived family support and Black Caribbean adolescents' sexual initiation suggests possible influences of Black heterogeneity stemming from ethnic identity differences in sexual health decision-making.

自尊的中介作用：加勒比黑人和非裔美国青少年的性行为开始

确定自尊如何调节美国出生的加勒比黑人与非裔美国青少年的家庭支持和开始性行为之间的关系。对来自美国全国生活调查 - 青少年增刊 (2003–2004) 的 1170 名青少年的回答进行了二次数据分析。进行了加权描述性统计和逻辑回归分析，以检查在感知到的家庭支持下开始性行为是否由自尊介导。研究人群由 360 名加勒比黑人和 810 名非裔美国青少年组成。加勒比黑人青少年 (42.1%) 的性开始流行率高于非裔美国青少年 (36.75%)。加勒比黑人青少年开始性行为的调整优势比为 0.85（95% 置信区间 [CI]：0.16-4。51) 与非裔美国青少年的 0.59 (95% CI: 0.35–1.00) 相比。自尊代表了统计上显着的中介路径，对于非裔美国青少年的性健康可能比黑加勒比地区更重要。自尊在感知到的家庭支持和加勒比黑人青少年的性开始之间的毫无根据的中介作用表明，黑人异质性的可能影响源于性健康决策中的种族身份差异。
