ARCHIVED - Early Prenatal Care

Early Prenatal Care
Note: Early Prenatal Care is the proportion of births where mother received early prenatal care divided by the total number births where prenatal care start time was known, by geography. Births with unknown start of care are not included in the denominator.

Early prenatal care is defined here as care beginning during 1st trimester of pregnancy. This does not account for frequency of care.
Limitation: Beginning in 2007, "Date of first prenatal visit" was collected in addition to the "Month prenatal care began" on birth certificates. This affects comparability of statistics before and after 2007.

Prepared by: County of San Diego, Health & Human Services Agency, Public Health Services, Community Health Statistics Unit, 2019.

Sample Interpretation: "85% of all births in Geography X received prenatal care".

早期孕产期保健

注：早期孕产期保健比例指接受早期孕产期保健的母亲出生数占总已知孕产期保健开始时间的出生总数的比例，按地域划分。未知的保健开始时间出生数不包含在分母中。

在此，早期孕产期保健被定义为妊娠早期（孕早期）开始的保健。此定义不计入保健频率。

局限性：自2007年起，在出生证明上除了收集“孕产期保健开始月份”外，还收集了“首次孕产期就诊日期”。这影响了2007年前后统计数据的一致性。

数据来源：加利福尼亚州公共卫生部，健康统计与信息中心，出生统计主文件和出生公共使用文件。圣地亚哥县，卫生与公共服务署，公共卫生服务，孕产妇、儿童和家庭健康服务（MCFHS）。

编制单位：圣地亚哥县，卫生与公共服务署，公共卫生服务，社区健康统计单元，2019。

样本解读：‘地理X地区85%的所有出生都接受了孕产期保健’。
