To assess whether women having preconceptional health care utilization were more likely to have early initiation of prenatal care than were women not having preconceptional health care utilization.
In this cohort study, data were collected prospectively from a population-based Perinatal Health Care Surveillance System in China. The analysis included 195 796 women who delivered single live births in 13 cities/counties during 1997 to 2000. Mantel-Haenszel test was employed to calculate risk ratios and 95% confidence intervals (CI). Multivariate logistic regression was conducted to assess the association between preconceptional health care utilization and early initiation of prenatal care after controlling for maternal residence, age at delivery, educational attainment, occupation, parity, preconceptional medical disorders, and high-risk medical experiences during the first trimester. SPSS 11.5 (SPSS Inc.) was employed for data analysis.
Women having preconceptional health care utilization were 2.6 times (95%CI: 2.5 to 2.6) more likely to have early initiation of prenatal care compared with women not having preconceptional health care utilization. When stratified by maternal residence, age at delivery, educational attainment, occupation, parity, preconceptional medical disorder, high-risk medical experiences during the first trimester, and preconceptional medical disorders, this association still existed. After controlling for stratification factors mentioned above and the interaction of maternal age, educational attainment, and parity, women having preconceptional health care utilization were 2.7 times (95%CI: 2.6 to 2.8) more likely to have early initiation of prenatal care than were women not having preconceptional health care utilization.
Women who had preconceptional health care utilization were more likely to have early prenatal care than were women not having preconceptional health care utilization.
评估进行孕前保健的女性比未进行孕前保健的女性更早开始产前检查的可能性是否更高。
在这项队列研究中，前瞻性地收集了来自中国一个基于人群的围产期保健监测系统的数据。分析纳入了1997年至2000年期间在13个市/县分娩单活胎的195796名女性。采用Mantel-Haenszel检验计算风险比和95%置信区间（CI）。在控制了产妇居住地、分娩年龄、教育程度、职业、产次、孕前疾病以及孕早期的高危医疗经历后，进行多因素逻辑回归分析以评估孕前保健利用与早期开始产前检查之间的关联。使用SPSS 11.5（SPSS公司）进行数据分析。
与未进行孕前保健的女性相比，进行孕前保健的女性更早开始产前检查的可能性高2.6倍（95%CI：2.5至2.6）。按产妇居住地、分娩年龄、教育程度、职业、产次、孕前疾病、孕早期的高危医疗经历以及孕前疾病进行分层时，这种关联仍然存在。在控制上述分层因素以及产妇年龄、教育程度和产次的相互作用后，进行孕前保健的女性比未进行孕前保健的女性更早开始产前检查的可能性高2.7倍（95%CI：2.6至2.8）。
进行孕前保健的女性比未进行孕前保健的女性更有可能更早开始产前检查。
