Effects of a simple educational intervention in well-baby clinics on women's knowledge about and intake of folic acid supplements in the periconceptional period: a controlled trial.

ABSTRACT:

Objective

To test the hypothesis that a concise intervention to promote the preconception use of folic acid (FA) supplements among mothers who visit a well-baby clinic (WBC) for the 6-month check-up of their youngest child is effective. Effectiveness was measured as intention to use or actual use of FA supplements before a next pregnancy among women who expected to be pregnant within 0-12 months.

Design

Controlled intervention study with independent samples of intervention and control mothers. The intervention took place at the 6-month visit. A post-intervention measurement was done in the intervention group and a comparable measurement in the control group at the 11-month check-up visit.

Setting

The intervention, verbal and in writing, was implemented in four Dutch WBC and given by the WBC physician to the mothers who visited the WBC.

Subjects

All mothers visiting the WBC were eligible for inclusion, unless they were unable to complete a questionnaire. The intervention group consisted of 198 (68 %) mothers recruited from 291 6-month intervention visits and the control group of 215 (84%) mothers recruited from 255 11-month normal visits.

Results

In mothers who expected to be pregnant within 0-12 months, the proportion using or intending to use FA was 65% in the intervention group (n 49) v. 42% in the control group (n 43; difference 23%, 95% CI 4, 43%, P<0·05).

Conclusions

Health education intervention at the 6-month WBC visit is an effective means to promote the use of FA supplements or the intention to do so.

Project description:BackgroundWomen attending mammography screening units (msus) and well women's clinics (wwcs) represent a motivated cohort likely to engage in interventions aimed at primary breast cancer (bca) prevention.MethodsWe used a feasibility questionnaire distributed to women (40-49 or 50-74 years of age) attending msus and wwcs in Halifax, Nova Scotia, to examine■ women's views about bca primary prevention and sources of health care information,■ prevalence of lifestyle-related bca risk factors, and■ predictors of prior mammography encounters within provincial screening guidelines.Variables examined included personal profiling, comorbidities, prior mammography uptake, lifestyle behaviours, socioeconomic status, health information sources, and willingness to discuss or implement lifestyle modifications, or endocrine therapy, or both. A logistic regression analysis examined associations with prior mammography encounters.ResultsOf the 244 responses obtained during 1.5 months from women aged 40-49 years (n = 75) and 50-74 years (n = 169), 56% and 75% respectively sought or would prefer to receive health information from within, as opposed to outside, health care. Lifestyle-related bca risk factors were prevalent, and most women were willing to discuss or implement lifestyle modifications (93%) or endocrine therapy (67%). Of the two age groups, 49% and 93% respectively had previously undergone mammography within guidelines. Increasing age and marital status (single, separated, or divorced vs. married or partnered) were independent predictors of prior mammography encounters within guidelines for women 40-49 years of age; no independent predictors were observed in the older age group.ConclusionsWomen attending msus and wwcs seem to largely adhere to mammography guidelines and appear motivated to engage in bca primary prevention strategies, including lifestyle modifications and endocrine therapy. Women's views as observed in this study provide a rationale for the potential incorporation of bca risk assessment within the "mammogram point of care" to engage motivated women in bca primary prevention strategies.

Project description:BackgroundFolate, including the folic acid form, is a key component of the one-carbon metabolic pathway used for DNA methylation. Changes in DNA methylation patterns during critical development periods are associated with disease outcomes and are associated with changes in nutritional status in pregnancy. The long-term impact of periconceptional folic acid supplementation on DNA methylation patterns is unknown.ObjectivesTo determine the long-term impact of periconceptional folic acid supplementation on DNA methylation patterns, we examined the association of the recommended dosage (400 μg/d) and time period (periconceptional before pregnancy through first trimester) of folic acid supplementation with the DNA methylation patterns in the offspring at age 14-17 y compared with offspring with no supplementation.MethodsTwo geographic sites in China from the 1993-1995 Community Intervention Program of folic acid supplementation were selected for the follow-up study. DNA methylation at 402,730 CpG sites was assessed using saliva samples from 89 mothers and 179 adolescents (89 male). The mean age at saliva collection was 40 y among mothers (range: 35-54 y) and 15 y among adolescents (range: 14-17 y). Epigenome-wide analyses were conducted to assess the interactions of periconceptional folic acid exposure, the 5,10-methylenetetrahydrofolate reductase (MTHFR)-C677T genotype, and epigenome-wide DNA methylation controlling for offspring sex, geographic region, and background cell composition in the saliva.ResultsIn the primary outcome, no significant differences were observed in epigenome-wide methylation patterns between adolescents exposed and those non-exposed to maternal periconceptional folic acid supplementation after adjustment for potential confounders [false discovery rate (FDR) P values < 0.05]. The MTHFR-C677T genotype did not modify this lack of association (FDR P values < 0.05).ConclusionsOverall, there were no differences in DNA methylation between adolescents who were exposed during the critical developmental window and those not exposed to the recommended periconceptional/first-trimester dosage of folic acid.
