Interventions to Increase Multivitamin Use Among Women in the Interconception Period: An IMPLICIT Network Study.

INTRODUCTION: Each year, 3% of infants in the Unites States (US) are born with congenital anomalies, including 3000 with neural tube defects. Multivitamins (MVIs) including folic acid reduce the incidence of these birth defects. Most women do not take recommended levels of folic acid prior to conception or during the interconception period. METHODS: The Interventions to Minimize Preterm and Low Birth Weight Infants through Continuous Improvement Techniques (IMPLICIT) ICC model was implemented to screen mothers who attend well child visits (WCVs) for their children aged 0-24 months. Mothers were queried for maternal behavioral risks known to affect pregnancy including multivitamin use and use of family planning methods to enhance birth spacing. When appropriate, interventions targeted at those at risk behaviors are offered. A mixed effects logistic regression model was used to calculate the odds ratio (OR) of behavior change in MVI use among mothers who reported not using MVIs. RESULTS: 37.7% of mothers reported not using MVIs at WCVs. 64.0% of mothers received an intervention to improve MVI use in this model. Mothers who received an intervention were more likely to report taking an MVI at the subsequent WCV if they received advice to take MVIs (OR 1.64) or directly received MVI samples (OR 3.09). CONCLUSIONS: Dedicated maternal counseling during pediatric WCVs is an opportunity to influence behavioral change in women at risk of becoming pregnant. Direct provision of MVIs increases the odds that women will report taking them at a higher rate than provider advice or no counseling at all.

Systematic review and meta-analysis of the effectiveness of pre-pregnancy care for women with diabetes for improving maternal and perinatal outcomes.

BACKGROUND: Pre-gestational diabetes mellitus is associated with increased risk of maternal and perinatal adverse outcomes. This systematic review was conducted to evaluate the effectiveness and safety of pre-conception care (PCC) in improving maternal and perinatal outcomes. METHODS: Databases from MEDLINE, EMBASE, WEB OF SCIENCE, and Cochrane Library were searched, including the CENTRAL register of controlled trials, and CINHAL up until March 2019, without any language restrictions, for any pre-pregnancy care aiming at health promotion, glycemic control, and screening and treatment of diabetes complications in women with type I or type II pre-gestational diabetes. Trials and observational studies were included in the review. Newcastle-Ottawa scale and the Cochrane collaboration methodology for data synthesis and analysis were used, along with the GRADE tool to evaluate the body of evidence. RESULTS: The search identified 8500 potentially relevant citations of which 40 reports of 36 studies were included. The meta-analysis results show that PCC reduced congenital malformations risk by 71%, (Risk ratio (RR) 0.29; 95% CI: 0.21-0.40, 25 studies; 5903 women; high-certainty evidence). The results also show that PCC may lower HbA1c in the first trimester of pregnancy by an average of 1.27% (Mean difference (MD) 1.27; 95% CI: 1.33-1.22; 4927 women; 24 studies, moderate-certainty evidence). Furthermore, the results suggest that PCC may lead to a slight reduction in the risk of preterm delivery of 15%, (RR 0.85; 95% CI: 0.73-0.99; nine studies, 2414 women; moderate-certainty evidence). Moreover, PCC may result in risk reduction of perinatal mortality by 54%, (RR 0.46; 95% CI: 0.30-0.73; ten studies; 3071 women; moderate-certainty evidence). There is uncertainty about the effects of PCC on the early booking for antenatal care (MD 1.31; 95% CI: 1.40-1.23; five studies, 1081 women; very low-certainty evidence) and maternal hypoglycemia in the first trimester, (RR 1.38; 95% CI: 1.07-1.79; three studies; 686 women; very low- certainty evidence). In addition, results of the meta-analysis indicate that PCC may lead to 48% reduction in the risk of small for gestational age (SGA) (RR 0.52; 95% CI: 0.37-0.75; six studies, 2261 women; moderate-certainty evidence). PCC may reduce the risk of neonatal admission to intensive care unit (NICU) by 25% (RR 0.75; 95% CI: 0.67-0.84; four studies; 1322 women; moderate-certainty evidence). However, PCC may have little or no effect in reducing the cesarean section rate (RR 1.02; 95% CI: 0.96-1.07; 14 studies; 3641 women; low-certainty evidence); miscarriage rate (RR 0.86; 95% CI: 0.70-1.06; 11 studies; 2698 women; low-certainty evidence); macrosomia rate (RR 1.06; 95% CI: 0.97-1.15; nine studies; 2787 women, low-certainty evidence); neonatal hypoglycemia (RR 0.93; 95% CI: 0.74-1.18; five studies; 880 women; low-certainty evidence); respiratory distress syndrome (RR 0.78; 95% CI: 0.47-1.29; four studies; 466 women; very low-certainty evidence); or shoulder dystocia (RR 0.28; 95% CI: 0.07-1.12; 2 studies; 530 women; very low-certainty evidence). CONCLUSION: PCC for women with pre-gestational type 1 or type 2 diabetes mellitus is effective in improving rates of congenital malformations. In addition, it may improve the risk of preterm delivery and admission to NICU. PCC probably reduces maternal HbA1C in the first trimester of pregnancy, perinatal mortality and SGA. There is uncertainty regarding the effects of PCC on early booking for antenatal care or maternal hypoglycemia during the first trimester of pregnancy. PCC has little or no effect on other maternal and perinatal outcomes.

Vaccinating in Pregnancy: Opportunities and Challenges.

The continuum of preconception, antenatal period, fourth trimester, and interconception period are a critical time for comprehensive care to advance maternal-child health and deliver family-centered care. Immunizations are a key component of this care delivery; however, there are intricacies around indications of vaccinations during this key period. Both active immunity to the individual receiving the vaccine as well as passive immunity passed to the fetus during pregnancy highlight the benefits of this care. Understanding the indications and benefits of vaccine administration during this continuum is critical for providers caring for individuals of reproductive age.

Optimizing interconception care: Rationale for the IMPLICIT model.

Despite traditional prenatal interventions, the incidence of low birth weight and prematurity in the United States have not significantly decreased. Interconception care for women between pregnancies has been proposed as a method of improving various perinatal outcomes. Although broadly advocated by national groups, interconception care (ICC) has not been widely implemented. We describe best practices for an ICC model based on screening mothers for tobacco use, depression, folic acid intake, and inter-pregnancy interval at well child visits. Because of the model's flexibility, sites can readily customize implementation by incorporating the questions directly into existing workflows and using local service providers already working in maternal-child health. This model has demonstrated promising results and ease of implementation thus far, and offers great potential for improved perinatal outcomes and promotion of health equity.

Co-designing preconception and pregnancy care for healthy maternal lifestyles and obesity prevention.

PROBLEM: A recognised gap exists between current and recommended practices in the provision of lifestyle advice and weight management support for women across preconception and pregnancy care. BACKGROUND: Preconception and pregnancy are critical stages for promoting healthy maternal lifestyles and obesity prevention. Co-design is a novel approach with the potential to strengthen existing models of care to facilitate the implementation of clinical practice guidelines promoting preconception and pregnancy health, especially in relation to preconception weight management and preventing excessive gestational weight gain. AIM AND METHODS: The aims of this discussion paper are to (i) define co-design in the context of preconception and pregnancy care, (ii) outline key considerations when planning co-design initiatives and (iii) describe co-design opportunities in preconception and pregnancy care for promoting women's health and obesity prevention. DISCUSSION: While several definitions of co-design exist, one critical element is the meaningful involvement of all key stakeholders. In this discussion, we specifically identified the involvement of women and expanding the role of practice nurses in primary care may assist to overcome barriers to the provision of healthy lifestyle advice and support for women during preconception. Co-designing pregnancy care will involve input from women, nurses, midwives, obstetricians, allied health and administration and management staff. Additional attention is required to co-design care for women considered most at-risk. CONCLUSION: There is potential to enhance current provision of preconception and pregnancy care using co-design. Nursing and midwifery professions are active across both preconception and pregnancy and therefore, they have an important role to play.

Integrating interconception care in preventive child health care services: The Healthy Pregnancy 4 All program.

BACKGROUND: Most parents with young children pay routine visits to Well-Baby Clinics, or so-called Preventive Child Health Care (PCHC) services. This offers a unique opportunity to promote and deliver interconception care. This study aimed to integrate such care and perform an implementation evaluation. METHODS: In seven Dutch municipalities, PCHC professionals were instructed to discuss the possibility of an interconception care consultation during each routine six-months well-baby visit. The primary outcome of this study was coverage of the intervention, quantified as the proportion of visits during which women were informed about interconception care. Secondary outcomes included adoption, fidelity, feasibility, appropriateness, acceptability and effectiveness of the intervention, studied by surveying PCHC professionals and women considering becoming pregnant. RESULTS: The possibility of interconception care was discussed during 29% (n = 1,849) of all visits, and 60% of the PCHC physicians adopted the promotion of interconception care by regularly informing women. About half of the PCHC professionals and most women judged integration of interconception care in PCHC appropriate and acceptable. Estimated feasibility was poor, since 13% of the professionals judged future integration in daily practice as probable. The uptake of interconception care consultations was low (n = 4 consultations). CONCLUSIONS: Promotion of interconception care was achieved in approximately one-third of the routine PCHC consultations and appeared promising with regards to adoption, appropriateness and acceptability. However, concerns on feasibility and uptake of interconception care consultations in daily practice remain. Suggestions for improvement may include further integration of interconception care health promotion in routine PCHC consultations, while allocating sufficient resources.

Regional Overview on Maternal and Child Nutrition and Examples of Nutrition Governance and Policy Responses: Europe, Central Asia and Eastern Mediterranean Regions.

The Eastern Mediterranean Regions and Europe and Central Asia Regions are facing an epidemiological and nutrition transition, especially among vulnerable groups including mothers, children and adolescents. This has led to a double burden of malnutrition (DBM). Poor infant and young child feeding (IYCF), poor dietary diversity, excessive consumption of energy dense unhealthy foods, a growing obesogenic environment for children, including aggressive marketing of unhealthy foods for children, and reduced physical activity are among the main causes. In addition, several countries in the region lack the nutrition governance capacity to respond effectively to the DBM. This article reviews the context and provides a set of conclusions in which countries are called to reduce the marketing of unhealthy foods for children, enforce the fortification of staple foods with micronutrients to reduce micronutrient deficiencies and improve IYCF, including breastfeeding in the region. Also, the call is strong for cross-border multi-sectoral efforts to address the DBM in these regions.

Regional Overview on Maternal Nutrition and Examples of Health System Programme and Policy Responses: Asia and the Pacific.

BACKGROUND: The double burden of malnutrition in Asia and the Pacific is driving a renewed focus on maternal malnutrition. SUMMARY: Though adverse consequences of maternal malnutrition have been long recognized, there is slow progress in addressing nutritional problems of women/adolescent girls. Coverage and quality of current maternal nutrition interventions, mostly delivered through antenatal care programmes vary across countries, and are often sub-optimum. Further, despite a marked increase in overweight and obesity in women of reproductive age, at present, most programmes are focused on under-nutrition and micronutrient deficiencies. Key Messages: The recent antenatal care recommendations released by World Health Organization provide a benchmark for countries to evaluate their programmes and identify gaps and challenges to improving maternal nutrition. Asian and Pacific countries need to address all forms of maternal malnutrition. For countries that historically focused on maternal under-nutrition, expanding their programmes to incorporate interventions to address overweight and obesity will be challenging. Innovative methods for nutrition counselling, both in terms of content and using novel channels of communication, are needed. Protocols and guidance on managing excessive weight gain as well as determining appropriate pregnancy weight gains are needed, while managing micronutrient deficiencies, particularly in settings where inherited disorders of red blood cells exist.

Regional Overview on the Double Burden of Malnutrition and Examples of Program and Policy Responses: Latin America and the Caribbean.

BACKGROUND: Hunger, food insecurity, stunting, anemia, overweight, and noncommunicable diseases (NCDs) may coexist in the same person, household, and community in Latin America and the Caribbean (LAC). The double burden of malnutrition (DBM) is an important cause of disability and premature death, which could be addressed with comprehensive policies such as the Plan of Action for the Prevention of Obesity in Children and Adolescents. This paper summarizes the main policies and actions aimed to prevent undernutrition and obesity. SUMMARY: Several countries are implementing the Plan of Action, Caribbean Public Health Agency is actively supporting Ministries of Health, Education, and Sport to develop school nutrition policies and strategies to create health-promoting environments at school and in their surrounding communities. Chile is implementing the comprehensive child protection system "Chile Crece Contigo" that integrates health, social development, and educational activities to optimize growth and childhood cognitive-motor development. Brazil is implementing policies and plans to commit to international targets regarding food and nutrition security, NCDs and their risk factors. Key Messages: The DBM exists in the Americas and contributes to disability and premature death. The Region is making progress implementing policies and actions addressing the DBM. However, stronger political will and leadership are needed to enact legislation and policies that create and support enabling -environments.

Did an urban perinatal health programme in Rotterdam, the Netherlands, reduce adverse perinatal outcomes? Register-based retrospective cohort study.

OBJECTIVES: To study the effect of an urban perinatal health programme in Rotterdam, the Netherlands, on perinatal outcomes. DESIGN: A retrospective cohort study with difference-in-differences analysis using individual-level perinatal outcome data from the Dutch Perinatal Registry 2003-2014 linked to Central Bureau of Statistics data of migration background and individual disposable household income. INTERVENTION: The programme consisted of perinatal health promotion, risk selection and risk-guided pregnancy care, and a new primary care child birth centre. The programme was implemented during 2009-2012. PRIMARY OUTCOME MEASURES: We compared trends in perinatal mortality, preterm delivery and small-for-gestational-age births between targeted urban neighbourhoods in Rotterdam (n=61 415) and all other urban neighbourhoods in the Netherlands (n=881 202). The effect of the programme was modelled as a change in trend of each perinatal outcome in the treatment group post intervention compared with the control population from January 2010 onwards. All analyses were adjusted for maternal age, parity, ethnicity and individual-level low socioeconomic status (SES). We also conducted a stratified analysis by SES. RESULTS: During 2003-2014, downward trends in perinatal mortality (adjusted OR (aOR) 0.9439 per year, 95% CI 0.9362 to 0.9517), preterm birth (aOR 0.9970 per year, 95% CI 0.9944 to 0.9997) and small-for-gestational-age births (aOR 0.9809 per year, 95% CI 0.9787 to 0.9831) in the entire study population were observed. No demonstrable changes in these trends were found in the intervention group after the programme had started. The stratified analyses by SES showed no changes in trends post intervention in both strata either. CONCLUSIONS: The programme had no demonstrable effects on perinatal outcomes. The intervention may not have reached a sufficient proportion of the population or has provided too little contrast to the widespread attention for inequalities in pregnancy outcomes occurring simultaneously in the Netherlands.

Availability of Services Related to Achieving Pregnancy in U.S. Publicly Funded Family Planning Clinics.

BACKGROUND: Recognizing that quality family planning services should include services to help clients who want to become pregnant, the objective of our analysis was to examine the distribution of services related to achieving pregnancy at publicly funded family planning clinics in the United States. METHODS: A nationally representative sample of publicly funded clinics was surveyed in 2013-2014 (n = 1615). Clinic administrators were asked about several clinical services and screenings related to achieving pregnancy: basic infertility services, reproductive life plan assessment, screening for body mass index, screening for sexually transmitted diseases, provision of natural family planning services, infertility treatment, and primary care services. The percentage of clinics offering each of these services was compared by Title X funding status; prevalence ratios (PRs) and 95% confidence intervals (CIs) were estimated after adjusting for clinic characteristics. RESULTS: Compared to non-Title X clinics, Title X clinics were more likely to offer reproductive life plan assessment (adjusted PR [aPR], 1.62; 95% CI, 1.42-1.84), body mass index screening for men (aPR, 1.10; 95% CI, 1.01-1.21), screening for sexually transmitted diseases (aPRs ranged from 1.21 to 1.37), and preconception health care for men (aPR, 1.10; 95% CI, 1.01-1.20). Title X clinics were less likely to offer infertility treatment (aPR, 0.55; 95% CI, 0.40-0.74) and primary care services (aPR, 0.74; 95% CI, 0.68-0.80) and were just as likely to offer basic infertility services, preconception health care services for women, natural family planning, and body mass index screening in women. CONCLUSIONS: The availability of selected services related to achieving pregnancy differed by Title X status. A follow-up assessment after publication of national family planning recommendations is underway.

Preconception health in England: a proposal for annual reporting with core metrics.

There is growing interest in preconception health as a crucial period for influencing not only pregnancy outcomes, but also future maternal and child health, and prevention of long-term medical conditions. Successive national and international policy documents emphasise the need to improve preconception health, but resources and action have not followed through with these goals. We argue for a dual intervention strategy at both the public health level (eg, by improving the food environment) and at the individual level (eg, by better identification of those planning a pregnancy who would benefit from support to optimise health before conception) in order to raise awareness of preconception health and to normalise the notion of planning and preparing for pregnancy. Existing strategies that target common risks factors, such as obesity and smoking, should recognise the preconception period as one that offers special opportunity for intervention, based on evidence from life-course epidemiology, developmental (embryo) programming around the time of conception, and maternal motivation. To describe and monitor preconception health in England, we propose an annual report card using metrics from multiple routine data sources. Such a report card should serve to hold governments and other relevant agencies to account for delivering interventions to improve preconception health.

The Use of a Community-Based Preconception Peer Health Educator Training Intervention to Improve Preconception Health Knowledge.

This paper highlights the use of an adapted Office of Minority Health (OMH) Preconception Health Peer Educator program to address persistent infant mortality health disparities. The community-based Attack Infant Mortality (AIM Escambia) initiative was established to increase preconception health knowledge among African American women at risk for adverse birth outcomes. Participants (N = 122) attended a 6-h AIM peer educator training, completed pretest and posttest questionnaires about their health knowledge, health attitudes, and planned engagement in health behaviors. Study results support the use of preconception health education training to inform health knowledge, health attitudes, and planned health sharing behaviors. Multidisciplinary collaborations and targeted interventions should be considered when seeking to improve community health conditions and increase health knowledge and health literacy for minority populations.

Conditions and Dynamics That Impact Maternal Health Literacy among High Risk Prenatal-Interconceptional Women.

The purpose of the study was to describe conditions and dynamics in the lives of high-risk, low-income, Southern United States prenatal-interconceptional women (n = 37) in a home visiting program that promoted maternal health literacy progression. In the Life Course Health Development (LCHD) Model, conditions were risk and protective factors that impacted health. Dynamics drove the complex, epigenetic relationships between risk and protective factors. Maternal health literacy promotion helped participants address conditions and dynamics to create positive life changes. This research was a retrospective, mixed methods study of women's service records documenting care from prenatal admission to 24 months post-delivery. The Life Skills Progression Instrument (LSP) was scored to measure maternal health literacy progression. Ethnographic content analysis of visit notes triangulated with quantitative data enabled specificity of critical data elements. Subsequently, a complementary focus group was conducted with the Registered Nurse Case Managers (RNCM). Severe social conditions included devastating poverty, low educational achievement, transient housing, unstable relationships, incarceration, lack of continuous health insurance, and shortage of health care providers. Dynamics included severe psycho-social stressors, domestic violence, lack of employment, low income, low self-esteem and self-expectations, and social/family restraints upon women's intended positive changes. An important protective factor was the consistent, stable, evidence-informed relationship with the RNCM. Findings from the focus group discussion supported content analysis results.

Men's Preconception Health: A Primary Health-Care Viewpoint.

The purpose of this article is to theoretically explore men's preconception health as a mechanism to enhance fertility, as well as the health and well-being of the subject and his descendants. Premorbid risk factors and behaviors associated with stress, environmental toxins, excessive alcohol consumption, smoking, lack of exercise/obesity, and the use of illicit drugs are all known to affect fecundity. While there are many health clinics available to women, where advice in areas such as postnatal care of the newborn, family planning, and couples fertility is provided, there are few, if any, equivalent health clinics available to men. Additionally, getting men to attend primary health-care services has also been continuously problematic, even in the context of there being a clearly discernible need for treatment. It is argued in this article that an impetus is required to encourage men to focus on and improve their preconception health and to utilize primary health-care services to take action. An assertive men's preconception health outlook can positively influence the conjugal relationship, fathering, male self-esteem, and continued good health. Using the sometimes complex concept of preconception health as a motivating factor for healthy lifestyle adaptation has the potential to improve male fertility outcomes and general health and well-being, as well as the health of future generations.

Pregnancy in Diabetes: challenges and opportunities for improving pregnancy outcomes.

Our aim was to review the data from the National Pregnancy in Diabetes (NPID) audit, and to identify the challenges and opportunities for improving pregnancy outcomes in women with diabetes. We reviewed three years of NPID data and relevant diabetes and obstetric literature, and found that there has been little change in pregnancy preparation or outcomes over the past 3 years, with substantial clinic-to clinic variations in care. Women with Type 2 diabetes remain less likely to take 5 mg preconception folic acid (22.8% vs. 41.8%; P < 0.05), and more likely to take potentially harmful medications (statin and/or ACE inhibitor 13.0% vs. 1.8%; P < 0.05) than women with Type 1 diabetes. However, women with Type 1 diabetes are less likely to achieve the recommended glucose control target of HbA1c < 48 mmol/mol (6.5%) (14.9% vs. 38.1%; P < 0.05). The following opportunities for improvement were identified. First, the need to integrate reproductive health into the diabetes care plans of all women with diabetes aged 15-50 years. Second, to develop more innovative approaches to improve uptake of pre-pregnancy care in women with Type 2 diabetes in primary care settings. Third, to integrate insulin pump, continuous glucose monitoring and automated insulin delivery technologies into the pre-pregnancy and antenatal care of women with Type 1 diabetes. Fourth, to improve postnatal care with personalized approaches targeting women with previous pregnancy loss, congenital anomaly and perinatal mortality. A nationwide commitment to delivering integrated reproductive and diabetes healthcare interventions is needed to improve the health outcomes of women with diabetes.

Improving preconception health and care: a situation analysis.

BACKGROUND: The purpose of this situation analysis was to explore the views of health and non-health professionals working with women of childbearing age on current and future delivery of preconception care in one National Health Service (NHS) Board area in Scotland. METHODS: The situation analysis was undertaken using a mixed methods approach. Six focus groups were conducted organised by profession - general practitioners (GPs), practice nurses, health visitors, family nurses, guidance teachers and youth workers. Existing evidence of effective preconception care interventions informed focus group guides. A survey was undertaken with community pharmacists which provided qualitative data for analysis. Focus group transcripts were analysed by two researchers using a thematic analysis approach. RESULTS: There was lack of awareness of preconception health and its importance amongst the target group. Levels of unplanned pregnancy hampered efforts to deliver interventions. Professional knowledge, capacity and consistency of practice were viewed as challenges, as was individual compliance with preconception care advice. Improvement requires multifaceted action, including ensuring the school curriculum adequately prepares adolescents for future parenthood, increasing awareness through communication and marketing, supporting professional knowledge and practice and capitalising on existing opportunities for preconception care, and ensuring services are equitable and targeted to need. CONCLUSIONS: Delivery of preconception care needs to be improved both before and between pregnancies to improve outcomes for women and infants. Action is required at individual, organisational and community levels to ensure this important issue is at the forefront of preventative care and preventative spending.
