ABSTRACT Folic acid use started prior to pregnancy confers a decreased risk of neural tube defects, and yet 20-50% of pregnancies are unplanned. We sought to determine whether medical providers order folic acid (FA) or folic acid-containing multivitamins (MVI) for their non-pregnant female patients of childbearing age. This is a cross-sectional study using data from the CDC's National Ambulatory Medical Care Survey (NAMCS) and National Hospital Ambulatory Medical Care Survey (NHAMCS) (2005 and 2006). Among non-pregnant, female patients of childbearing age (15-44), the proportion of preventive visits during which a provider ordered FA/MVI supplements was determined and compared to pregnant patients. Next, the rates of FA/MVI orders were examined according to race/ethnicity, age, insurance status, region of the country, provider type, contraceptive care, income and education. Analyses were conducted using SAS-callable Sudaan to account for survey design and to obtain population estimates. There were 4,634 preventive visits for non-pregnant women of childbearing age, representing 32.1 million visits nationally. Of these visits, 7.2% included provider-ordered FA/MVI. Multivariable logistic regression analyses revealed that provider-ordered FA/MVI was most common for women ages 30-34, who receive Medicaid, and whose race/ethnicity was other than White, Black or Hispanic. Preventive care visits represent an important venue for counseling regarding the benefits of FA for women of childbearing age, but appear to be under-utilized in all women. Our findings suggest that annually there may be over 29 million missed opportunities to recommend folic acid to non-pregnant women seeking preventive care.

    ABSTRACT: Objective:The American College of Obstetricians and Gynecologists and the American Psychiatric Association both recommend pharmacotherapy for perinatal depression when the benefits outweigh the risks. While minority adults are less likely to use antidepressant medications compared with non-Hispanic Whites, whether this pattern occurs among pregnant women is unclear. We sought to determine the frequency of antidepressant medication use reported during ambulatory care visits for pregnant women and whether these rates varied by race.Study Design:We combined the 2006-2010 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey to obtain nationally representative estimates of outpatient preventive care visits for pregnant women. We then obtained estimates of the prevalence of reported depression and antidepressant use during outpatient visits for pregnant women. To determine whether these estimates varied by race, we used multivariable logistic regression analyses accounting for survey design using SAS 9.2 (PROC SURVEYLOGISTIC) to estimate odds ratios of reported antidepressant use after adjustment for age, insurance status and region of the country.Result:Antidepressant use was reported during 2.2% of all outpatient visits for pregnant women. Providers indicated a depression diagnosis in 4.5% of visits. Among visits for depressed pregnant women, providers reported antidepressant use 25.4% of the time for all visits. Antidepressant use during pregnancy varied significantly by race/ethnicity. Among visits for non-Hispanic White women, 3.1% included a code for antidepressant use vs just 1.0% for non-White women (P<0.0001). After adjustment for age, insurance status and region of the country, this association persisted with non-Hispanic White (vs non-White) pregnant women having higher odds of antidepressant use (adjusted OR 3.3, 95% confidence intervals 2.1, 5.3).Conclusion:Non-Hispanic White women were more likely than non-White women to be using antidepressants during pregnancy. Whether differences in antidepressant use by race/ethnicity indicates over-treatment of non-Hispanic White women or under-treatment of minorities remains unclear. This disparity warrants investigation with the goal of optimizing maternal mental health while minimizing potential adverse sequelae of antidepressants on developing fetuses.Journal of Perinatology advance online publication, 20 November 2014; doi:10.1038/jp.2014.197.

    ABSTRACT: Despite the institution of mandatory folic acid fortification in the US, folate deficiencies still occur and are associated with an increased risk of several conditions. Since little is known regarding the relationship between folate status and other clinical, demographic, and healthcare-related characteristics, the objective of the study was to compare healthcare-related characteristics among US child-bearing age women with low vs normal red blood cell (RBC) folate levels. Data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) were used to conduct a retrospective cohort study. Women (aged 18-45 when surveyed) were categorized in two cohorts for comparison: normal RBC folate level (≥ 140 ng/ml, NFL) and low RBC folate level (<140 ng/ml, LFL). Of the 2816 subjects, 5.9% were assigned to the LFL cohort and were significantly younger (28 vs 30 years, p=0.01); a greater proportion were 18-25 years old (55.7% vs 39.9%, p<0.001) or African-American (55.1% vs 22.3%, p<0.01). A lower proportion of LFL women were insured (67.3% vs 75.5%, p=0.01) with low rates of private insurance (39.5% vs 53.1%, p<0.01), while Medicaid/SCHIP coverage was similar (16.8% vs 15.1%, p=0.56). Predictors of low folate levels included aged 36-45 years (OR: 2.14 [95% CI: 1.04, 4.39]) and never being married (2.65 [1.34, 5.24]), while a household income ≥ $75,000 reduced the likelihood of having low folate levels (0.20 [0.06, 0.73]). The proportion of women with low folate levels was small, with the sample size limiting the ability to adjust for other factors during analysis. Medical histories were based on patient interviews and are subject to recall bias. LFL women are younger and have low rates of private insurance coverage compared to women with normal folate levels. Differences in age, marital status, and household income are associated with folate status.

    ABSTRACT: Healthy diet, physical activity and appropriate weight gain during pregnancy contribute to healthy birth outcomes. The Institute of Medicine recommends that women receive counseling about diet and exercise during preconception, pregnancy and postpartum periods. We sought to determine how often healthcare providers report counseling women of childbearing age about diet or exercise and if such rates vary by pregnancy, overweight/obesity status or physician specialty. We combined the 2005-2010 National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey to obtain nationally representative estimates of outpatient preventive care visits for women of child-bearing age (15-44 years). Accounting for survey design, we compared proportions of preventive visits that included diet/exercise counseling for pregnant women versus non-pregnant women and performed multivariable logistic regression models to estimate odds ratios. Providers reported counseling pregnant women about diet/exercise during 17.9 % of preventive care visits compared to 22.6 % of visits for non-pregnant women (P < 0.01, adj. OR 0.8, 95 % CI 0.7, 1.0). Overweight/obese pregnant (vs. non-pregnant) women were significantly less likely to receive diet/exercise counseling (adj. OR 0.7, CI 0.5, 0.9) as were women seen by OB/GYNs versus non-OB/GYNs (adj. OR 0.4, CI 0.3, 0.5). Our findings suggest that provider-reported diet/exercise counseling rates during preventive care visits for women of childbearing age vary by overweight/obesity and pregnancy statuses, as well as by provider specialty. Our data suggest that there may be missed opportunities to provide diet/exercise counseling and that increasing rates of counseling could result in improved maternal and infant health outcomes.
