Introduction
|
|
Conditions prior to conception and during pregnancy impact the birth outcome. The California County Profile Reports include several prenatal
risk factors. The risk of having suboptimal pregnancy outcomes increases in women who are experiencing their sixth or higher birth (grand
multiparous). Similarly, there is increased risk for women who give birth less than 24 months after a previous birth (short birth interval).
|
|
The Healthy People 2020 Objectives establish guidelines for the remaining two factors in this section
of the California County Profile Reports, namely:
|
| 2. | Increasing the percent of births to women who enter prenatal care in the first trimester to 77.9 percent. |
| 3. | Increasing the percent of births to women experiencing early and adequate prenatal care to 77.6 percent. |
|

The California County Profile Reports include information on timing of entry into prenatal care and on the the adequacy of prenatal care
received.

|
Definitions
|
|
Grand multiparous mothers are women who have had six or more births (including the current birth).
Note that fetal deaths are included in the count of previous births.
|
|
The birth certificate collects information on the months between the current and the previous birth. The previous birth can be a live birth
or fetal death. A birth interval is considered short if the number of months between the current and last birth is less than 24.
|
|
A woman is considered to enter prenatal care late if she never receives prenatal care or if her first prenatal visit occurs after the first trimester of pregnancy.
|
|
The Adequacy of Prenatal Care Index (APNCU or Kotelchuck index) is based on two independent components: the initiation (timing) of prenatal care and the number of
prenatal visits adjusted for the length of gestation. A woman is considered to have experienced inadequate prenatal care if the APNCU index (Kotelchuck index)
indicates late or intermediate and/or too few prenatal care visits for the length of gestation. For a detailed description of and additional information on the APNCU index,
