Little is known about male high school students who have been involved in a pregnancy. This study was undertaken to determine whether male involvement with a pregnancy during adolescence is associated with other risk and problem behaviors.
The 1993 Massachusetts Youth Risk Behavior Survey was conducted on a random sample of 3054 9th- through 12th-grade students. The use of tobacco, alcohol, and other drugs, early and multiple sexual experiences, fighting resulting in injury, and demographic variables were compared between sexually active young men who reported being involved in pregnancy (n = 82) and their counterparts who reported not ever causing a pregnancy (n = 537). Associations were measured using chi 2 analyses and Kruskal-Wallis analysis of variance. Stepwise logistic regression was used to further analyze those variables significantly associated with involvement with a pregnancy.
Based on logistic regression, older age and earlier ages of onset of cocaine use, initial sexual intercourse, and regular use of cigarettes were associated with being involved with a pregnancy. An increased lifetime frequency of cocaine use, lifetime frequency of alcohol use, and an increased number of lifetime sexual partners were also associated with having caused a pregnancy. Those who reported involvement with a pregnancy reported a higher frequency of being injured in a fight during the past year, drinking while driving, and having multiple sexual partners during the previous 30 days than those who had not gotten someone pregnant.
A history of being involved with a pregnancy clustered with other health risk and problem behaviors to form a "risk behavior syndrome." These findings suggest that when risk behaviors are encountered during the routine comprehensive screening of male adolescents, strategies for pregnancy prevention among young men should also be emphasized.
对于使女性怀孕的男性高中生，人们了解甚少。本研究旨在确定青春期男性与怀孕相关是否与其他风险及问题行为有关。
1993年马萨诸塞州青少年风险行为调查对3054名9至12年级学生的随机样本进行。比较了报告使女性怀孕的性活跃年轻男性（n = 82）及其报告从未致孕的同龄人（n = 537）在烟草、酒精和其他药物使用、过早及多次性经历、打架致伤以及人口统计学变量方面的情况。使用卡方分析和克鲁斯卡尔 - 沃利斯方差分析来测量相关性。采用逐步逻辑回归进一步分析与怀孕相关的那些显著变量。
基于逻辑回归，年龄较大以及可卡因使用起始年龄较早、初次性交年龄较早和经常吸烟与使女性怀孕有关。可卡因使用终生频率增加、酒精使用终生频率增加以及终生性伴侣数量增加也与致孕有关。报告使女性怀孕的人在过去一年打架受伤频率更高、酒后驾车以及在前30天有多个性伴侣，这都高于未使他人怀孕的人。
有使女性怀孕的经历与其他健康风险及问题行为聚集在一起，形成一种“风险行为综合征”。这些发现表明，在对男性青少年进行常规全面筛查时遇到风险行为时，也应强调针对年轻男性的怀孕预防策略。
