Promoting preconception health of women is a key public health strategy in the United States to decrease morbidity and mortality associated with adverse maternal and infant outcomes. In 2006, CDC published 10 recommendations for improving the health of women before pregnancy (1); one recommendation proposed maximizing public health surveillance to monitor preconception health. Toward this end, data collected in Oklahoma (the only state to develop a detailed survey question on preconception health) during 2000--2003 from the Pregnancy Risk Assessment Monitoring System (PRAMS) were analyzed to 1) estimate the prevalence of women who did not report three selected preconception health indicators, (i.e., pre-pregnancy awareness of folic acid benefits,* multivitamin consumption,† and receipt of health-care counseling§) and 2) identify those subpopulations of women who were more likely not to report these indicators. Results of this analysis indicated that 21.5% of Oklahoma women with a recent live birth were not aware of folic acid benefits before they became pregnant, 73.5% did not consume multivitamins at least four times per week during the month before pregnancy, and 84.8% did not receive preconception counseling from a health-care provider. Subpopulations of women with characteristics (at the time of conception) significantly associated (p<0.05) with not reporting at least two of the three indicators included those who were younger, were unmarried, had <12 years of education, had no health insurance, had an unintended pregnancy, or had a previous live birth. Other states might use this analysis to help develop preconception health questions to be included in their own PRAMS surveys; Oklahoma state and local health officials can use the results to help prioritize preconception health objectives and identify subpopulations of women in need of targeted programs.
PRAMS is an ongoing state- and population-based surveillance system designed to monitor self-reported behaviors and experiences that occur before, during, and after pregnancy among women who deliver live-born infants. PRAMS is administered by CDC in collaboration with state health departments and follows standard data-collection procedures.¶ Self-reported survey data are linked to birth certificate data and weighted for sample design, nonresponse, and noncoverage. The PRAMS questionnaire consists of core questions that appear on all state surveys and state-developed questions tailored to meet the individual needs of states. Additional details regarding PRAMS have been described previously (4).
Data from Oklahoma were analyzed because Oklahoma was the only state to develop a detailed question for its PRAMS questionnaire regarding preconception health: "Before you became pregnant with your new baby, did any of these things happen? a) You heard or read that taking vitamins with folic acid could help prevent some birth defects; and b) you received advice or counseling from a health-care provider to prepare for becoming pregnant." Preconception multivitamin use was ascertained from a PRAMS core question used by all states: "In the month before you got pregnant with your new baby, how many times a week did you take a multivitamin (a pill that contains many different vitamins and minerals)?" The percentage of women who did not report each of these indicators was estimated overall and stratified by selected characteristics. To identify significant associations between women in subpopulations with selected characteristics and not reporting each indicator, multiple logistic regression was used to calculate adjusted odds ratios (AORs) and 95% confidence intervals (CIs). All calculations were performed using data weighted to Oklahoma population data. The average annual weighted survey response rates during 2000--2003 was 81.3% (range: 79.9%--83.7%).
Results indicated that, during 2000--2003, among Oklahoma women who had recently delivered a live-born infant, 21.5% were not aware of folic acid benefits before they became pregnant, 73.5% did not consume multivitamins at least four times per week during the month before pregnancy, and 84.8% did not receive preconception counseling from a health-care provider (Table). Lack of awareness of folic acid benefits before pregnancy was greatest among women who were aged <20 years (39.4%), black (40.7%), or enrolled in Medicaid (39.2%). The prevalence of not consuming multivitamins at least four times a week in the month before pregnancy was greatest among women who were aged <20 years (87.4%), who were unmarried (85.2%), who had <12 years of education (83.9%), who had no health insurance (84.1%), or whose pregnancy was unintended (84.4%). Not receiving preconception counseling was most common among women who were Hispanic (91.4%), who were unmarried (90.1%), who had no health insurance (92.3%), or whose pregnancy was unintended (93.4%).
Subpopulations of women with characteristics significantly associated with lack of pre-pregnancy awareness of folic acid benefits included those who were aged <20 (AOR = 1.9), 20--24 (AOR = 1.5), or >35 (AOR = 1.5) years, compared with those aged 25--34 years; who were black (AOR = 2.0) or American Indian (AOR = 1.5), compared with those who were white; who were unmarried (AOR = 1.8), compared with those who were married; who had <12 (AOR = 2.3) or 12 (AOR = 2.1) years of education, compared with those who had >12 years of education; or whose pregnancy was unintended (AOR = 1.5), compared with those whose pregnancy was intended (Table). Subpopulations of women with characteristics significantly associated with not consuming multivitamins at least four times per week 1 month before pregnancy included those who were aged <20 (AOR = 1.8) or 20--24 (AOR = 1.7) years; who were unmarried (AOR = 1.5); who had 12 years of education (AOR = 1.5); who had no health insurance (AOR = 1.7), compared with those who had private insurance; whose pregnancy was unintended (AOR = 2.6); or who had a previous live birth (AOR = 1.4), compared with those who did not have a previous live birth. Subpopulations of women with characteristics significantly associated with not receiving preconception counseling included those who were Hispanic (AOR = 1.9), compared with those who were not Hispanic; uninsured (AOR = 2.2); whose pregnancy was unintended (AOR = 5.1); or who had a previous live birth (AOR = 1.9).
