Teenage motherhood and smoking have important health implications for youth in the United States and globally, but the link between teen childbearing and subsequent smoking is inadequately understood. The selection of disadvantaged young women into early childbearing and smoking may explain higher smoking levels among teen mothers, but teen motherhood may also shape subsequent smoking through compromised maternal depression or socioeconomic status, and race/ethnicity may condition these processes.
This study examines the relationship between US teen childbearing and subsequent daily smoking, accounting for prior smoking and selection processes related to social disadvantage. Analyses investigate whether socioeconomic status and depression in young adulthood explained any relationship between teen childbearing and daily smoking, as well as examining racial/ethnic heterogeneity in these processes.
Multivariate binary logistic regression analyses employ the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 7,529).
The highest daily smoking prevalence occurred among non-Hispanic White teen mothers, with lower prevalence among Hispanic and non-Hispanic Black teen mothers. Compared to other women, teenage mothers are 2.5 times as likely to smoke daily in young adulthood. Their greater likelihood of daily smoking is due in part to selection and is also mediated by socioeconomic status in ways that differ by race/ethnicity.
The findings suggest that preventing teen pregnancy or ameliorating its socioeconomic consequences may decrease daily smoking in this vulnerable population. Reducing teen smoking, especially during pregnancy, could improve teen, maternal, and infant health and thereby increase US health and longevity.
This study provides new, nationally representative information about selection, mediation, and heterogeneity processes in the relationship between teen childbearing and subsequent smoking.
青少年母亲生育和吸烟对美国及全球的年轻人都有重要的健康影响，但青少年生育与随后吸烟之间的联系尚未得到充分理解。弱势年轻女性选择过早生育和吸烟可能解释了青少年母亲中较高的吸烟率，但青少年母亲身份也可能通过母亲抑郁或社会经济地位受损影响随后的吸烟行为，而且种族/族裔可能会影响这些过程。
本研究考察美国青少年生育与随后每日吸烟之间的关系，同时考虑既往吸烟情况以及与社会劣势相关的选择过程。分析调查年轻成年期的社会经济地位和抑郁是否解释了青少年生育与每日吸烟之间的任何关系，并检验这些过程中的种族/族裔异质性。
多变量二元逻辑回归分析采用青少年到成人健康的全国纵向研究（“加健康”研究；N = 7529）。
非西班牙裔白人青少年母亲的每日吸烟率最高，西班牙裔和非西班牙裔黑人青少年母亲的吸烟率较低。与其他女性相比，青少年母亲在成年早期每日吸烟的可能性是其他女性的2.5倍。她们每日吸烟可能性较高部分归因于选择因素，并且社会经济地位也起到了中介作用，其方式因种族/族裔而异。
研究结果表明，预防青少年怀孕或改善其社会经济后果可能会降低这一弱势群体的每日吸烟率。减少青少年吸烟，尤其是孕期吸烟，可改善青少年、母亲和婴儿的健康状况，从而提高美国的健康水平和寿命。
本研究提供了关于青少年生育与随后吸烟之间关系中的选择、中介和异质性过程的新的、具有全国代表性的信息。
