A Latent Class Analysis: Identifying Pregnancy Intention Classes Among U.S. Adolescents

Abstract

Purpose: Few studies have captured the multidimensionality of pregnancy intentions for adolescents on a national level, particularly missing the perspectives of male adolescents. Therefore, this study aimed to identify and describe pregnancy intention profiles among U.S. adolescents.

Methods: Latent class analysis was conducted using data from two cycles of the National Survey of Family Growth (2015-2017 and 2017-2019) among U.S. adolescents 15-19 years old (N = 3,812). Stratified by sex, six National Survey of Family Growth indicators around desires, feeling, timing, and social acceptability were included. Multinomial logistic regression was used to identify the correlates of class membership.

Results: Three latent classes of pregnancy intention were identified for each sex, which were distinguished by immediate and future desires, feelings, timing, and social acceptability. For both females and males, Delayed Pro-pregnancy (53% vs. 82%) and Near Pro-pregnancy (28% vs. 8%) were identified. Ambivalent-pregnancy (14%) and Anti-pregnancy (10%) were specific to females and males, respectively. Near Pro-pregnancy females and Anti-pregnancy males were more likely to be sexually active, older, of Hispanic descent, report receiving public assistance, and have a teen mother than adolescents classified as Delayed Pro-pregnancy. Females with a pregnancy history were more likely to be classified as Ambivalent than Delayed Pro-pregnancy.

Discussion: While most adolescents intend to delay or avoid childbearing, there are subsets of adolescents whose pregnancy intentions are in favor of early childbearing, which is often dismissed in adolescent sexual and reproductive health. Current efforts can use these distinct pregnancy intention classes to tailor sexual and reproductive health services specifically for diverse adolescent populations.
