Early pregnancies and their poor reproductive outcomes remain increasing concerns.
This study aims to investigate the pregnancy rate and outcomes and to identify social factors associated with pregnancy among Chinese unmarried youths aged 15-24 years.
Data were obtained from the Survey of Youth Access to Reproductive Health in China, and 11,076 unmarried female youths were analyzed. Prevalence of pregnancy by various demographic and socioeconomic characteristics was calculated. Univariate and multivariable logistic regression models were used to identify factors associated with pregnancy.
The main outcome is pregnancy among unmarried female youths during their lifetime.
Among 11,076 female youths, 501 individuals reported 697 premarital pregnancies during their lifetime until the survey was conducted, approximately 62.9 (95% CI: 58.5-67.6) pregnancies per 1,000 female youths. Older age group (odds ratio [OR] = 4.49; 95% CI = 3.60-5.59), low education levels (primary school and below: OR = 1.78, 95% CI = 1.33-2.37; junior and senior high school: OR 1.44, 95% CI = 1.15-1.80), living in non-eastern regions (central: OR 1.34, 95% CI = 1.06-1.68; west: OR 1.62, 95% CI = 1.28-2.04), cigarette smoking (OR 3.60, 95% CI = 2.76-4.70), alcohol drinking (OR 1.59, 95% CI = 1.28-1.97), from family with mother's education of primary school and below (OR 1.65, 95% CI = 1.11-2.46), and the bottom economic status (OR 1.48, 95% CI = 1.14-1.91) were associated with higher risk of premarital pregnancy among female youths.
The findings justify the national concern for pregnancy among unmarried youth in China. Strategies to improve sexual education in school and family, to enhance the reproductive services for youth, and to increase public awareness of the reproductive health of young people were warranted.

早期妊娠及其不良生殖结局一直是日益受到关注的问题。
本研究旨在调查妊娠率和结局，并确定中国15至24岁未婚青年中与妊娠相关的社会因素。
数据来自中国青年生殖健康调查，对11076名未婚青年女性进行了分析。计算了不同人口统计学和社会经济特征的妊娠患病率。采用单变量和多变量逻辑回归模型来确定与妊娠相关的因素。
主要结局是未婚青年女性一生中的妊娠情况。
在11076名青年女性中，501人报告在调查前一生中发生了697次婚前妊娠，每1000名青年女性中约有62.9次（95%置信区间：58.5 - 67.6）妊娠。年龄较大组（比值比[OR]=4.49；95%置信区间=3.60 - 5.59）、低教育水平（小学及以下：OR = 1.78，95%置信区间=1.33 - 2.37；初中和高中：OR 1.44，95%置信区间=1.15 - 1.80）、居住在非东部地区（中部：OR 1.34，95%置信区间=1.06 - 1.68；西部：OR 1.62，95%置信区间=1.28 - 2.04）、吸烟（OR 3.60，95%置信区间=2.76 - 4.70）、饮酒（OR 1.59，95%置信区间=1.28 - 1.97）、母亲受教育程度为小学及以下的家庭（OR 1.65，95%置信区间=1.11 - 2.46）以及经济状况最差（OR 1.48，95%置信区间=1.14 - 1.91）与青年女性婚前妊娠风险较高相关。
这些发现证明了国家对中国未婚青年妊娠问题的关注是合理的。有必要采取策略改善学校和家庭中的性教育，加强针对青年的生殖服务，并提高公众对青少年生殖健康的认识。郭C，庞L，丁R等。中国未婚青年妊娠、结局及社会因素：基于全国人群调查的结果。性医学2019；7：396 - 402。
