Trends in Folic Acid Awareness and Behavior in the United States: The Gallup Organization for the March of Dimes Foundation Surveys, 1995–2005

Objective: To summarize changes in folic acid awareness, knowledge, and behavior among women of childbearing age in the United States since the U.S. Public Health Service (USPHS) 1992 folic acid recommendation and later fortification. Methods: Random-digit dialed telephone surveys were conducted of approximately 2000 women (per survey year) aged 18–45 years from 1995–2005 in the United States. Results: The percentage of women reporting having heard or read about folic acid steadily increased from 52% in 1995 to 84% in 2005. Of all women surveyed in 2005, 19% knew folic acid prevented birth defects, an increase from 4% in 1995. The proportion of women who reported learning about folic acid from health care providers increased from 13% in 1995 to 26% in 2005. The proportion of all women who reported taking a vitamin supplement containing folic acid increased slightly from 28% in 1995 to 33% in 2005. Among women who were not pregnant at the time of the survey in 2005, 31% reported taking a vitamin containing folic acid daily compared with 25% in 1995. Conclusions: The percentage of women taking folic acid daily has increased modestly since 1995. Despite this increase, the data show that the majority of women of childbearing age still do not take a vitamin containing folic acid daily. Health care providers and maternal child health professionals must continue to promote preconceptional health among all women of childbearing age, and encourage them to take a vitamin containing folic acid daily.

Communication monitoring: shaping CDC's emergency risk communication efforts

CDC develops and delivers health messages for a variety of audiences, including the public, health care professionals, public health researchers and practitioners, and policy makers. News media outlets--because of their broad reach and potential to influence knowledge, attitudes, and behaviors--are major channels for disseminating messages to these audiences. CDC has routinely monitored news outlets to identify message/information gaps and opportunities. The 9/11 terrorist attacks and the anthrax incidents that followed required CDC to transform its media monitoring system into a broader communication monitoring system, with both listening and telling functions, to support CDCs public health emergency response.

A qualitative study of perceived barriers to management of diabetes among women with a history of diabetes during pregnancy.

BACKGROUND Uncontrolled diabetes during pregnancy can cause adverse maternal and infant outcomes. This study explored barriers to glycemic control before, during, and after pregnancy and describes knowledge, attitudes, and behaviors among pregnant women with pregestational diabetes (PGDM) or gestational diabetes (GDM). METHODS Focus groups were conducted in the Atlanta area among white, black, and Hispanic women who had diabetes during a recent pregnancy. Participants were a convenience sample drawn from a variety of sources. Nine focus groups were held with women who had GDM, and seven focus groups were held with women who had PGDM. RESULTS Participants identified five main areas of barriers to management of diabetes during pregnancy: financial barriers and difficulties accessing care, barriers to maintaining a healthy diet and exercising, communication difficulties, lack of social support, and barriers related to diabetes care. Participants with GDM had general awareness of possible diabetes complications but frequently could not name specific effects of diabetes on the woman or child during and after pregnancy. Most were unaware of their risk for developing type 2 diabetes later. Participants with PGDM expressed concern about the increased risk of adverse outcomes for the baby; most knew the importance of maintaining glycemic control during pregnancy. Low rates of pregnancy planning were reported in both groups. Pregnancy planning was not identified as a strategy to ensure a healthy baby. CONCLUSIONS The barriers to achieving glycemic control during pregnancy identified in this study could help inform future efforts to assist women in achieving optimal prepregnancy and intrapregnancy glycemic control.

Predicted contribution of folic acid fortification of corn masa flour to the usual folic acid intake for the US population: National Health and Nutrition Examination Survey 2001–2004

BACKGROUND Folic acid can prevent up to 70% of neural tube defects (NTDs) if taken before pregnancy. Compared with other race-ethnicities, Hispanic women have higher rates of NTDs, lower rates of folic acid supplement use, and lower total folic acid intakes. OBJECTIVE The objective was to assess potential effects of fortifying corn masa flour with folic acid on Mexican American women and other segments of the US population. DESIGN A model was developed by using data from the National Health and Nutrition Examination Survey 2001-2004 to estimate the folic acid content in foods containing corn masa flour if fortified at a level of 140 microg folic acid/100 g corn masa flour. RESULTS Had corn masa flour fortification occurred, we estimated that Mexican American women aged 15-44 y could have increased their total usual daily folic acid intake by 19.9% and non-Hispanic white women by 4.2%. Among the US population, estimated relative percentage increases in total usual daily folic acid intake with corn masa flour fortification were greatest among Mexican Americans (16.8%) and lowest among children aged 1-3 y (2%) and adults aged >51 y (0-0.5%). CONCLUSION Analyses suggest that corn masa flour fortification would have effectively targeted Mexican Americans, specifically, Mexican American women, without substantially increasing folic acid intake among other segments of the population. Such increases could reduce the disparity in total folic acid intake between Mexican American and non-Hispanic white women of childbearing age and implies that an additional NTD preventive benefit would be observed for Mexican American women.

Social marketing: planning before conceiving preconception care.

Social marketing approaches can help to shape the formation of and to create demand for preconception care services. This article describes four components of social marketing, often referred to as the 4 P’s, that should be carefully researched and set in place before a national effort to launch and sustain preconception care services is pursued. First, the product or package of services must be defined and adapted using the latest in scientific and health care standards and must be based on consumer needs and desires. Second, the pricing of the services in financial or opportunity costs must be acceptable to the consumer, insurers, and health care service providers. Third, the promotion of benefits must be carefully crafted to reach and appeal to both consumers and providers. Fourth, the placement and availability of services in the marketplace must be researched and planned. With the application of market research practices that incorporate health behavior theories in their exploration of each component, consumer demand for preconception care can be generated, and providers can take preconception care to the market with confidence.

Broadcasting Behavior Change A Comparison of the Effectiveness of Paid and Unpaid Media to Increase Folic Acid Awareness, Knowledge, and Consumption Among Hispanic Women of Childbearing Age

Awareness about folic acids effectiveness in reducing the risk of certain birth defects has increased among women in the United States; however, few Hispanic women are consuming enough folic acid daily. A 1998 survey conducted by the Gallup Organization for the National March of Dimes Birth Defects Foundation found that English-speaking Hispanic women had lower folic acid awareness (53% vs. 72%) and lower daily consumption (29% vs. 33%) than non-Hispanic White women. In 1999, the Centers for Disease Control and Prevention (CDC) conducted baseline surveys with Spanish-speaking Hispanic women in selected U.S. markets to measure folic acid awareness, knowledge, and consumption. A Spanish-language public service announcement (PSA) volunteer campaign and a paid Spanish-language media and community education campaign were conducted in 2000 and 2002, respectively. Comparisons of postcampaign surveys indicate that the paid media campaign was significantly more effective than the PSA campaign in increasing folic acid awareness, knowledge, and consumption among Spanish-speaking Hispanic women.

Maternal attitudes toward DNA collection for gene–environment studies: A qualitative research study†‡

To assess attitudes toward DNA collection in an epidemiological study, focus groups were assembled in September 2007 with mothers who had participated in a case–control study of birth defects. Each recruited mother previously had completed an interview and had received a mailed kit containing cytobrushes to collect buccal cells for DNA from herself, her infant, and her infants father during the period July 2004 through July 2007. A total of 38 mothers attended six focus groups comprising: (1) non‐Hispanic Black mothers of case infants who participated or (2) did not participate in DNA collection, (3) mothers of any race or ethnicity who had case infants of low birth weight who participated or (4) did not participate in DNA collection, and (5) non‐Hispanic Black mothers of control infants who participated or (6) did not participate in DNA collection. Moderator‐led discussions probed maternal attitudes toward providing specimens, factors that influenced decision making, and collection method preferences. Biologics participants reported that they provided DNA for altruistic reasons. Biologics nonparticipants voiced concerns about government involvement and how their DNA will be used. Information provided (or not provided) on DNA use, storage, and disposal influenced decision making. Biologics participants and nonparticipants reported that paternal skepticism was a barrier to participation. All mothers were asked to rank DNA collection methods in terms of preference (cytobrushes, saliva, mouthwash, newborn blood spots, and blood collection). Preferred methods were convenient and noninvasive. Better understanding attitudes toward DNA collection and preferred collection methods might allow more inclusive participation and benefit future studies.

The CDC Clear Communication Index Is a New Evidence-Based Tool to Prepare and Review Health Information

This article presents the Centers for Disease Control and Prevention Clear Communication Index (the Index), a tool that emphasizes the primary audience’s needs and provides a set of evidence-based criteria to develop and assess public communication products for diverse audiences. The Index consists of four open-ended introductory questions and 20 scored items that affect information clarity and audience comprehension, according to the scientific literature. A research team fielded an online survey to test the Index’s validity. Respondents answered 10 questions about either an original health material or one redesigned with the Index. For 9 out of 10 questions, the materials revised using the Index were rated higher than the original materials. Regardless of education level, respondents rated the revised materials more favorably than the original ones. The results indicate that the Index performed as intended and made it more likely that audiences could correctly identify the intended main message and understand the words and numbers in the materials. The results also support the widely held view that audiences are more positive about clearly designed materials. The Index shows that an evidence-based scoring rubric can assess and improve the clarity of health materials.

Developing Effective Campaign Messages to Prevent Neural Tube Defects: A Qualitative Assessment of Women's Reactions to Advertising Concepts

The incidence of neural tube defects (NTDs), serious birth defects of the brain and spine that affect approximately 3,000 pregnancies in the United States each year, can be reduced by 50–70% with daily periconceptional consumption of the B vitamin folic acid. Two studies were designed to assess college womens reactions to and perceptions of potential campaign advertising concepts derived from preproduction formative research to increase folic acid consumption through the use of a daily multivitamin. Study one assessed draft advertising concepts in eight focus groups (N = 71) composed of college-enrolled women in four cities geographically dispersed across the United States. Based on study one results, the concepts were revised and reassessed in study two with a different sample (eight focus groups; N = 73) of college women in the same four cities. Results indicated that participants generally responded favorably to concepts in each of the two studies, and provided insight into individual concepts to increase their overall appeal and effectiveness. The specific findings and implications of these results are discussed.

Understanding Optimal Nutrition Among Women of Childbearing Age in the United States and Puerto Rico: Employing Formative Research to Lay the Foundation for National Birth Defects Prevention Campaigns

Neural tube defects (NTDs) are serious birth defects of the brain and spine that affect approximately 3,000 pregnancies in the United States each year and affected 404 pregnancies in Puerto Rico from 1996 to 2002. Consuming the B vitamin folic acid can reduce the incidence of NTDs 50%–70%, and recent efforts to reduce NTD rates have focused on increasing the number of childbearing-aged women who take a vitamin containing folic acid every day. As the first stage of formative research in campaign planning, two exploratory, qualitative studies were conducted in order to (a) understand the complexity of vitamin use among women in the United States and Puerto Rico and (b) serve as a foundation on which to develop national communication and education interventions. Also, this information shed light on theories that might be used to guide campaign development. Results indicated that campaign messages designed to increase folic acid use through multivitamin supplementation in the United States must address womens barriers to vitamin use (e.g., cost, time), increase womens perceived need for multivitamins (e.g., identify immediate, tangible results from taking a daily multivitamin), and address the relationship between daily food choices and the need for supplementation. Future campaign messages in Puerto Rico must focus on many of these same issues, in addition to increasing womens knowledge about when folic acid should be taken in relation to pregnancy and addressing womens perceptions that vitamins cause weight gain (an undesirable outcome for most participants). The practical and theoretical implications of these results are discussed in terms of their contribution to the development of a creative new approach to increase multivitamin consumption among women of childbearing age in the United States and Puerto Rico.
