A national health objective for the year 2000 is to increase to at least 90% of the proportion of pregnant women who receive prenatal care during the first trimester of pregnancy (objective 14.11). Adequate prenatal care is believed to result in better pregnancy outcomes, including reduced maternal and infant morbidity and mortality and reduced risk for preterm delivery and for low birthweight (<2500 g [<5 lb 8 oz]). However, measures of prenatal-care utilization based on first-trimester initiation of prenatal care address only the timing of prenatal-care initiation and do not include the frequency of visits thereafter, which can provide a more comprehensive measure of prenatal-care utilization. To calculate rates of prenatal-care utilization for California during 1989-1994, the California Department of health Services (CDHS) analyzed data from birth certificates using a more comprehensive measure of prenatal-care utilization. This report presents annual rates of adequate prenatal-care utilization (APNCU) for California during 1989-1994 (the most recent year for which complete data were available), compares these data with the year 2000 objective for prenatal-care utilization, and examines rates of APNCU in California by payment source (for prenatal care) for 1989, 1992, and 1994.
2000年的一项全国性卫生目标是，将在孕早期接受产前护理的孕妇比例提高到至少90%（目标14.11）。人们认为，充分的产前护理会带来更好的妊娠结局，包括降低孕产妇和婴儿的发病率及死亡率，以及降低早产和低体重儿（<2500克[<5磅8盎司]）的风险。然而，基于孕早期开始产前护理的产前护理利用情况衡量指标仅涉及产前护理开始的时间，并未包括此后的就诊频率，而就诊频率能提供更全面的产前护理利用情况衡量指标。为计算1989 - 1994年加利福尼亚州的产前护理利用率，加利福尼亚州卫生服务部（CDHS）使用更全面的产前护理利用情况衡量指标对出生证明数据进行了分析。本报告呈现了1989 - 1994年（可获取完整数据的最近一年）加利福尼亚州充分产前护理利用率（APNCU）的年度数据，将这些数据与2000年产前护理利用目标进行了比较，并考察了1989年、1992年和1994年加利福尼亚州按产前护理支付来源划分的APNCU率。
