U.S. Latinas have a persistently high rate of teenage childbearing, which is associated with adverse outcomes for both mother and child. This study was designed to investigate the roles of socioeconomic factors and acculturation in teenage childbearing in this population.
Logistic regression was used to analyze the association of measures of acculturation (language spoken at home, nativity, and age at immigration) and respondents' parents' education with age at first birth in a stratified sample of post-partum women in California.
The unadjusted odds ratio for teenage birth for Latinas versus non-Latina Whites was 5.2 (95% CI 4.1-6.6). Nativity was not significantly associated with teen birth, but speaking Spanish at home was positively associated and immigrating at a later age was negatively associated with teen birth. Overall, these measures of acculturation accounted for 17% (95% CI 8-28%) of the difference in odds of teen birth between Latinas and non-Latina Whites. Higher levels of education among respondents' parents had differentially protective effects across the racial/ethnic groups. Controlling for disparities in respondents' parents' education without changing its differential effects across racial/ethnic groups reduced the odds ratio for Latinas compared to non-Latina Whites by 30% (95% CI 14-60%).
These findings call into question common assumptions about the protective effect of acculturation on teen fertility and suggest that improving childhood socioeconomic factors among Latinas may decrease teen childbearing.
美国拉丁裔少女的生育率一直居高不下,这对母婴双方都有不利影响。本研究旨在调查社会经济因素和文化适应在该人群中少女生育的作用。
使用逻辑回归分析了文化适应措施(在家中说的语言、出生地和移民年龄)和受访者父母的教育程度与加利福尼亚州产后妇女分层样本中首次生育年龄的关系。
与非拉丁裔白人相比,拉丁裔少女生育的未调整比值比为 5.2(95%置信区间 4.1-6.6)。出生地与少女生育无显著关联,但在家中说西班牙语呈正相关,移民年龄较大呈负相关。总体而言,这些文化适应措施解释了拉丁裔和非拉丁裔白人间少女生育几率差异的 17%(95%置信区间 8-28%)。受访者父母的教育程度越高,对不同种族/族裔群体的保护作用就越明显。在不改变其对不同种族/族裔群体的差异影响的情况下,控制受访者父母教育程度的差异,将拉丁裔与非拉丁裔白人间的比值比降低了 30%(95%置信区间 14-60%)。
这些发现对文化适应对青少年生育率的保护作用的常见假设提出了质疑,并表明改善拉丁裔少女的儿童社会经济因素可能会降低少女生育。
