Maternal folate status and placental vascular malperfusion: Findings from a high-risk US minority birth cohort.

INTRODUCTION: Maternal folate deficiency was associated with preeclampsia (PE) and PE was associated with placental maternal vascular malperfusion (MVM). However, no study has examined the association of maternal folate status with placental MVM. METHODS: We examined the association of maternal folate status and placental MVM in the Boston Birth Cohort. Primary exposure variables were maternal self-reported multivitamin supplement (<2, 3-5, >5 times/week) per trimester; and plasma folate levels (nmol/L) after birth. Primary outcome was presence/absence of placental MVM defined by the Amsterdam Placental Workshop Group standard classification. Covariates included demographics, chronic hypertension, clinically diagnosed PE, eclampsia and HELLP syndrome, gestational and pre-gestational diabetes, overweight/obesity, maternal cigarette smoking and alcohol use. Associations between folate and placental MVM were evaluated using multivariate logistic regressions. RESULTS: Of 3001 mothers in this study, 18.8% of mothers had PE, 37.5% had MVM. Mothers with the lowest self-reported frequency of folate intake had the highest risk of MVM (OR 1.45, 95% CI 1.03-2.05), after adjusting for the covariates. Consistently, among a subset of 939 mothers with plasma folate levels, folate insufficiency was associated with increased risk of MVM (OR 1.65, 95% CI 1.03-2.63), after adjusting for the covariables. As expected, mothers with low folate and placental MVM had highest rates of PE compared to those of high folate and no MVM (p < 0.001). DISCUSSION: In this high-risk birth cohort, low maternal folate status was associated with increased risk of placental MVM. Further investigation should explore the association between folate status, placental findings and the great obstetrical syndrome.

Cluster Randomized Trial of a Pre/Interconception Health Intervention for Mothers in Pediatric Visits.

OBJECTIVE: Recognizing that pediatric primary care focuses on family health and is an important location of contact for women of childbearing age, this project assessed the effectiveness of a pre/interconception women's health intervention delivered during pediatric primary care using a cluster randomized trial. METHODS: Pediatric clinicians were randomized to a screening and brief educational intervention group or usual care comparison group. Intervention group clinicians received training on pre/interconception care, including recommended counseling and referral resources for needs identified. Women presenting to primary care with their child ≤12 months were enrolled and assigned to the group corresponding to the assignment of their child's clinician. Mothers seen by clinicians in the intervention group completed a pre/interconception health screening tool and discussed results with their child's clinician during the visit. These mothers were compared to mothers seen by comparison group clinicians who did not receive the screening tool or clinician discussion. All enrolled mothers (Intervention and Comparison) received written preconception health information and a 90-day supply of multivitamins. Primary outcomes at 6 and 12 months post enrollment included contraception use, pregnancy, and access to and use of preventive health care. Secondary outcomes included daily folic acid supplementation, smoking, and substance use. RESULTS: A total of 415 women were enrolled and those who had at least 1 follow-up assessment were included in the analysis (n = 383). There was no significant effect of the intervention on contraceptive use, pregnancy incidence, or use of preventive care. Assignment to the intervention increased the odds of daily folic acid use (odds ratio 1.82, 95% confidence interval 1.25, 2.63) during follow-up. Intervention mothers were less likely to smoke at 6, but not 12 months. CONCLUSIONS: Pediatric visits are an opportune location for addressing maternal health and this intervention demonstrated feasibility and improved outcomes for some but not all outcomes. Attention to maternal health needs in pediatric visits during infancy may be important for maintaining positive pre/interconception health behaviors.

Vitamin D Trajectories From Birth to Early Childhood and Elevated Systolic Blood Pressure During Childhood and Adolescence.

Vitamin D deficiency is associated with hypertension in adults. It is unknown to what degree vitamin D status in early life can affect blood pressure (BP) a decade later. This study investigated the effect of vitamin D trajectory through early life on systolic BP (SBP) in childhood. This is a prospective birth cohort study of 775 children enrolled from 2005 to 2012 and followed prospectively up to age 18 years at the Boston Medical Center, Boston, MA. Persistent low vitamin D status is defined as plasma 25(OH)D <11 ng/mL at birth and <25 ng/mL in early childhood. Elevated SBP is defined as SBP ≥75th percentile. Low vitamin D status at birth was associated with higher risk of elevated SBP at ages 3 to 18 years: odds ratio, 1.38; (95% CI, 1.01-1.87) compared to those with sufficient vitamin D. Low vitamin D status in early childhood was associated with a 1.59-fold (95% CI, 1.02-2.46) higher risk of elevated SBP at age 6 to 18 years. Persistent low vitamin D status from birth to early childhood was associated with higher risk of elevated SBP (odds ratio, 2.04; [95% CI, 1.13-3.67]) at ages 3 to 18 years. These results suggest that low vitamin D status and trajectory in early life were associated with increased risk of elevated SBP during childhood and adolescence. Our findings will help inform future clinical and public health strategies for vitamin D screening and supplementation in pregnancy and childhood to prevent or reduce risk of elevated BP across the lifespan and generations.

Maternal postpartum plasma folate status and preterm birth in a high-risk US population.

OBJECTIVE: While maternal folate deficiency has been linked to poor pregnancy outcomes such as neural tube defects, anaemia and low birth weight, the relationship between folate and preterm birth (PTB) in the context of the US post-folic acid fortification era is inconclusive. We sought to explore the relationship between maternal folate status and PTB and its subtypes, i.e. spontaneous and medically indicated PTB. DESIGN: Observational study. SETTING: Boston Birth Cohort, a predominantly urban, low-income, race/ethnic minority population at a high risk for PTB.ParticipantsMother-infant dyads (n 7675) enrolled in the Boston Birth Cohort. A sub-sample (n 2313) of these dyads had maternal plasma folate samples collected 24-72 h after delivery. RESULTS: Unadjusted and adjusted logistic regressions revealed an inverse relationship between the frequency of multivitamin supplement intake and PTB. Compared with less frequent use, multivitamin supplement intake 3-5 times/week (adjusted OR (aOR) = 0·78; 95 % CI 0·64, 0·96) or >5 times/week (aOR = 0·77; 95 % CI 0·64, 0·93) throughout pregnancy was associated with reduced risk of PTB. Consistently, higher plasma folate levels (highest v. lowest quartile) were associated with lower risk of PTB (aOR = 0·74; 95 % CI 0·56, 0·97). The above associations were similar among spontaneous and medically indicated PTB. CONCLUSIONS: If confirmed by future studies, our findings raise the possibility that optimizing maternal folate levels across pregnancy may help to reduce the risk of PTB among the most vulnerable US population in the post-folic acid fortification era.

Folate Nutrition Status in Mothers of the Boston Birth Cohort, Sample of a US Urban Low-Income Population.

OBJECTIVES: To examine maternal folic acid supplementation and plasma folate concentrations in the Boston Birth Cohort, a predominantly urban, low-income, minority population in Boston, Massachusetts. METHODS: This report includes 7612 mothers with singleton live births (3829 Black, 2023 Hispanic, 865 White, and 895 others) enrolled in the Boston Birth Cohort at the Boston Medical Center, during 1999 to 2014. Folic acid supplementation during preconception and each trimester was obtained via interview questionnaire. In a subset (n = 2598), maternal plasma folate concentrations were measured in blood samples drawn within a few days of delivery. RESULTS: The percentage of mothers taking folic acid supplementation almost daily during preconception and the first, second, and third trimesters were 4.3%, 55.9%, 59.4%, and 58.0%, respectively. Most striking, we observed a wide range of maternal plasma folate concentrations, with approximately 11% insufficient (< 13.4 nmol/L) and 23% elevated (> 45.3 nmol/L). CONCLUSIONS: Findings indicate that fewer than 5% of mothers in the Boston Birth Cohort started folic acid supplements before pregnancy, and approximately one third of mothers had either too low or too high plasma folate levels, which may have important health consequences on both the mother and the child.

Association Between Preconception Counseling and Folic Acid Supplementation Before Pregnancy and Reasons for Non-Use.

To examine the relationship between folic acid preconception counseling (PCC) and folic acid use and reasons for non-use among women with a recent live birth. We analyzed Maryland Pregnancy Risk Assessment Monitoring System (PRAMS) survey responses from 2009 to 2011 (n = 4,426, response rate = 67%). Multivariable weighted logistic regression models were used to explore associations between folic acid PCC receipt and folic acid use and reasons for non-use. Approximately 30% of women reported daily folic acid use the month before pregnancy, with lower rates among those who were <30, non-white, or unmarried; received WIC during pregnancy; had suffered a stressful event prepregnancy; smoked prepregnancy; had a previous live birth; or had an unintended pregnancy (all p < 0.05). The most common reasons for folic acid non-use were "not planning pregnancy" (61%) and "didn't think needed to take" (41%). Folic acid PCC receipt was reported by 27% of women and was associated with three times the odds of folic acid use (adjusted odds ratio [aOR] 3.15, 95% CI 2.47-4.03) and half the odds of reporting "didn't think needed to take" (aOR 0.47, 95% CI 0.28-0.78) as a reason for non-use. Less than one-third of recent Maryland mothers reported using folic acid daily before pregnancy and only 27% reported receiving folic acid PCC. However, folic acid PCC was associated with increased folic acid use and decreased reporting that women did not think they needed to take folic acid. Our data support initiatives to promote provision of folic acid PCC to all women of childbearing age.

Merging systems: integrating home visitation and the family-centered medical home.

To improve the health of children and bend the health care cost curve we must integrate the individual and population approaches to health and health care delivery. The 2012 Institute of Medicine (IOM) report Primary Care and Public Health: Exploring Integration to Improve Population Health laid out the continuum for integration of primary care and public health stretching from isolation to merging systems. Integration of the family-centered medical home (FCMH) and home visitation (HV) would promote overall efficiency and effectiveness and help achieve gains in population health through improving the quality of health care delivered, decreasing duplication, reinforcing similar health priorities, decreasing costs, and decreasing health disparities. This paper aims to (1) provide a brief description of the goals and scope of care of the FCMH and HV, (2) outline the need for integration of the FCMH and HV and synergies of integration, (3) apply the IOM's continuum of integration framework to the FCMH and HV and describe barriers to integration, and (4) use child developmental surveillance and screening as an example of the potential impact of HV-FCMH integration.

Processes for effective communication in primary care.

Communication in the delivery of health care services occurs along 2 axes: between providers and patients and among several providers. In primary care, a principle objective in the provider-patient relationship is facilitating whole-person care, which is care provided in the context of family and community. In addition, primary care emphasizes communication between the primary care physician and other providers with the goal of integrated care, or care provided in the context of a patient's overall health care needs. However, considering both the U.S. health care delivery system and medical education programs, several obstacles interfere with the necessary processes of communication. This paper addresses those obstacles with a conceptual framework for effective communication in primary care. Recommendations propose formalizing requirements for the exchange of information among providers, enhancing communication training, disseminating information technology, and mitigating external factors that disrupt communication in primary care.
