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.

潜在类别分析：确定美国青少年的怀孕意向类别

目的

很少有研究在全国范围内捕捉到青少年怀孕意图的多维性，尤其是缺少男性青少年的观点。因此，本研究旨在识别和描述美国青少年的怀孕意向概况。

方法

潜在类别分析是使用来自美国 15-19 岁青少年（N = 3,812）的全国家庭成长调查（2015-2017 年和 2017-2019 年）的两个周期的数据进行的。按性别分层，包括六项围绕欲望、感觉、时间和社会可接受性的家庭成长全国调查指标。多项逻辑回归用于识别类成员的相关性。

结果

为每种性别确定了三种潜在的怀孕意图类别，分别以即时和未来的欲望、感觉、时间和社会可接受性来区分。对于女性和男性，均确定了延迟妊娠（53% 对 82%）和接近妊娠（28% 对 8%）。矛盾妊娠 (14%) 和抗妊娠 (10%) 分别针对女性和男性。与被归类为延迟怀孕的青少年相比，接近准怀孕的女性和抗怀孕的男性更有可能性活跃、年龄较大、西班牙裔后裔、报告接受公共援助并且有一个青少年母亲。有妊娠史的女性比延迟妊娠更容易被归类为矛盾型。

讨论

虽然大多数青少年打算推迟或避免生育，但也有一部分青少年的怀孕意图倾向于早育，而这在青少年性和生殖健康方面经常被忽视。目前的努力可以利用这些不同的怀孕意向类别来专门为不同的青少年群体量身定制性健康和生殖健康服务。
