Planning is not equivalent to preparing, how Dutch women perceive their pregnancy planning in relation to preconceptional lifestyle behaviour change - a cross-sectional study.

BACKGROUND: Unhealthy prenatal lifestyle behaviours are associated with adverse pregnancy outcomes, but little is known about what motivates women to comply with preconceptional lifestyle recommendations or consciously plan their pregnancy. Therefore, the objective of this study is to explore the associations between preconceptional lifestyle behaviours, health beliefs and pregnancy planning among Dutch pregnant women. METHODS: In this cross-sectional study based on the data of the APROPOS-II study, 1,077 low-risk pregnant women were eligible for inclusion. Preconception lifestyle behaviours and actively preparing for pregnancy were assessed in relation to planned pregnancies (based on the London Measure of Unplanned Pregnancies) and health beliefs (14 statements). The following preconceptional lifestyle behaviours were assessed through a self-administered questionnaire in the first trimester of pregnancy: fruit intake, vegetable intake, caffeine intake, (second-hand)smoking, alcohol intake, folic acid supplement use and exercise. Data were analysed using multivariate logistic regression analyses. RESULTS: A total of 921 (85.5%) women in our cohort had a planned pregnancy. However, of these women, 640 (69.5%) adequately used folic acid supplements and 465 (50.5%) women consumed alcohol at any point during pregnancy. Of the women considering themselves 'healthy enough and not needing preconception care', 48 (9.1%) women had an adequate vegetable intake, 294 (55.6%) women consumed alcohol at any point during pregnancy and 161 (30.4%) women were either over-or underweight. CONCLUSION: Despite consciously planning their pregnancy, most women did not adhere to preconceptional lifestyle behaviour recommendations. Women's health beliefs and overestimation of their health status seem to interfere with actively planning and preparing for pregnancy. Findings from our study may encourage the development of prospective health-promoting interventions that focus on health beliefs and actively preparing for pregnancy, to improve preconceptional lifestyle behaviours, thereby optimizing the health of future generations.

How to improve preconception care in a local setting? Views from Dutch multidisciplinary healthcare providers.

OBJECTIVE: To explore healthcare providers' views on improving preconception care in their region. DESIGN: Mixed-methods study. SETTING: Working conferences aimed to educate healthcare providers on preconceptional risk factors and conduct a region-specific analysis of barriers and facilitators for implementing preconception care, were organised in ten municipalities in the Netherlands. PARTICIPANTS: 250 healthcare providers of various disciplines attended a working conference and participated in the study. MEASUREMENTS AND FINDINGS: Participants were asked to both fill out a questionnaire concerning statements and experiences with preconception care and to participate in a workshop, to identify barriers and facilitators for the implementation of a local preconception care program. Almost all healthcare providers suggested that the responsibility for providing preconception care consultations lies within primary care (general practitioners (n = 239; 95.6%) and midwives (n = 236; 94.4%)). Professionals other than midwives found it significantly more difficult to start a conversation about a wish to conceive compared to midwives (26.8% versus 20.2%, p-value = 0.006) and felt less competent to provide preconceptional information (32.3% versus 15.1%, p-value = <0.001). Innovative facilitators were mentioned to improve reaching the target population with preconceptional information, i.e. the use of social media and local ambassadors. KEY CONCLUSION: While the responsibility for providing preconception care consultations is best suited with primary care, many other healthcare providers involved may act as referrers towards preconception care. Still, approximately 1 in 7 midwives (strongly) disagree with the statement that it is part of their job to provide preconceptional information to couples with a wish to conceive. IMPLICATIONS FOR PRACTICE: There is a need for integrating preconception care in many curricula and postgraduate courses, especially for non-midwives, to improve the delivery of preconception care. Insights in the suggested barriers and facilitators can improve the implementation of (local) preconception care programs.

Associations between periconceptional lifestyle behaviours and adverse pregnancy outcomes.

BACKGROUND: While the potential adverse outcomes of prenatal exposure to unhealthy lifestyle are widely evidenced, little is known about these exposures in the periconception period. We investigated the associations between lifestyle behaviours and adverse pregnancy outcomes with a unique distinction between preconceptional- and prenatal lifestyle behaviours. METHODS: A secondary analysis took place within a prospective multicentre cohort study in the Netherlands, including 3,684 pregnant women. Baseline characteristics and preconceptional and first trimester lifestyle behaviours were assessed through a self-administered questionnaire in the first trimester. Adverse pregnancy outcomes (hypertensive disorders in pregnancy (HDP), small for gestational age (SGA), gestational diabetes (GDM) and spontaneous preterm birth (sPTB)) were reported by healthcare professionals. Data were collected between 2012 and 2014 and analysed using multivariate logistic regression. RESULTS: Women who are overweight, and especially obese, have the highest odds of developing any adverse pregnancy outcome (adjusted odds ratio (aOR) 1.61 (95 % Confidence Interval (CI) 1.31-1.99) and aOR 2.85 (95 %CI 2.20-3.68), respectively), particularly HDP and GDM. Women who prenatally continued smoking attained higher odds for SGA (aOR 1.91 (95 %CI 1.05-1.15)) compared to the reference group, but these odds decreased when women prenatally quit smoking (aOR 1.14 (95 %CI 0.59-2.21)). Women who did not use folic acid supplements tended to have a higher odds of developing adverse pregnancy outcomes (aOR 1.28 (95 %CI 0.97-1.69)), while women who prenatally started folic acid supplements did not (aOR 1.01 (95 %CI 0.82-1.25)). CONCLUSIONS: Our results indicate that smoking cessation, having a normal body mass index (BMI) and initiating folic acid supplements preconceptionally may decrease the risk of adverse pregnancy outcomes. Therefore, intervening as early as the preconception period could benefit the health of future generations.

First effective mHealth nutrition and lifestyle coaching program for subfertile couples undergoing in vitro fertilization treatment: a single-blinded multicenter randomized controlled trial.

OBJECTIVE: To study compliance and effectiveness of the mHealth nutrition and lifestyle coaching program Smarter Pregnancy in couples undergoing in vitro fertilization (IVF) treatment with or without intracytoplasmic sperm injection (ICSI). DESIGN: Multicenter, single-blinded, randomized controlled trial, conducted from July 2014 to March 2017. SETTING: IVF clinics. PATIENT(S): A total of 626 women undergoing IVF treatment with or without ICSI and 222 male partners. INTERVENTIONS(S): Couples were randomly assigned to the light (control group) or regular (intervention group) Smarter Pregnancy program. Both groups filled out a baseline screening questionnaire on nutrition and lifestyle behaviors, and the intervention group received coaching tailored to inadequate behaviors during the 24-week period. MAIN OUTCOME MEASURE(S): Difference in improvement of a composite dietary and lifestyle risk score for the intake of vegetables, fruits, folic acid supplements, smoking, and alcohol use after 24 weeks of the program. RESULT(S): Compared with control subjects, women and men in the intervention group showed a significantly larger improvement of inadequate nutrition behaviors after 24 weeks of coaching. At the same time, the women also showed a significantly larger improvement of inadequate lifestyle behaviors. CONCLUSION(S): The mHealth coaching program Smarter Pregnancy is effective and improves the most important nutritional and lifestyle behaviors among couples undergoing IVF/ICSI treatment. International multicenter randomized trials are recommended to study the effect of using Smarter Pregnancy on pregnancy, live birth, and neonatal outcome. NETHERLANDS TRIAL REGISTER NUMBER: NTR4150.

A Mobile App Lifestyle Intervention to Improve Healthy Nutrition in Women Before and During Early Pregnancy: Single-Center Randomized Controlled Trial.

BACKGROUND: Unhealthy nutrition contributes to the worldwide rising prevalence of noncommunicable diseases. As most adverse reproductive outcomes originate during the periconception period, effective interventions targeting this period are needed. Therefore, we developed the lifestyle intervention Smarter Pregnancy to empower women to adapt a healthy diet prior to conception and during early pregnancy and performed a randomized controlled trial. OBJECTIVE: The objectives of this trial were to investigate compliance and effectiveness in women using the Smarter Pregnancy program. METHODS: Women aged between 18 and 45 years who were contemplating pregnancy or <13 weeks pregnant and their male partners living in the urban area of Rotterdam, the Netherlands, were eligible for participation. After baseline screening, the intervention group received personal online coaching based on identified inadequate intakes of vegetables, fruits, and folic acid supplements. The sum of these risk factors was used as a dietary risk score (DRS), ranging from 0 (healthy) to 9 (unhealthy). The control group did not receive coaching. We applied an intention-to-treat principle and used a multivariable linear regression model to evaluate the change in DRS after 24 weeks. Compliance was defined as the percentage of women who completed the screening questionnaire at 24 weeks. RESULTS: Of women recruited, 81.2% (177/218) completed the program (intervention: 91/218, 83.5%; control: 86/218, 78.9%; P=.95). After 24 weeks, the reduction in DRS of women in the intervention group was significantly larger than in the control group (ß=.75, 95% CI 0.18-1.34). This reduction was mainly due to increased vegetable intake (ß=.55, 95% CI 0.25-0.86). CONCLUSIONS: The high compliance and the larger improvements in nutritional behaviors, especially vegetable intake, in women in the intervention group emphasizes the effectiveness of empowering women by using the lifestyle change intervention Smarter Pregnancy.

The Impact of Neighbourhood Deprivation on Embryonic Growth Trajectories: Rotterdam Periconception Cohort.

BACKGROUND: Neighbourhood deprivation is a risk factor for impaired health and adverse pregnancy outcomes. We investigated whether living in a deprived neighbourhood is associated with embryonic growth. METHODS: From the Predict cohort, we studied 566 women who underwent repeated first trimester ultrasound examinations. Crown rump length (CRL; n = 1707) and embryonic volume (EV; n = 1462) were measured using three-dimensional techniques. Neighbourhood deprivation was assessed using the neighbourhood status scores (NSS) of the Dutch Social Cultural Planning office. A high NSS represents a non-deprived neighbourhood. Associations between the NSS and embryonic growth were investigated using linear mixed models. Adjustment was performed for individual-level factors: maternal age, geographic origin, educational level, BMI, folic acid supplement use, fruit and vegetable intake, alcohol use and smoking habits. RESULTS: The NSS was negatively associated with embryonic growth: a higher score (a less deprived neighbourhood) was associated with a smaller CRL and EV; adjusted ß: -0.025 (95% CI -0.046, -0.003) and adjusted ß: -0.015 (95% CI -0.026, -0.003). At 11 weeks of pregnancy, we observed a 0.55 cm3 smaller EV (7.65 cm3 vs. 7.10 cm3) and 1.08 mm smaller CRL (43.14 mm vs. 42.06 mm) in the highest compared to the lowest category. CONCLUSION: In deprived neighbourhoods, embryos are larger than in non-deprived neighbourhoods.

The impact of maternal lifestyle factors on periconception outcomes: a systematic review of observational studies.

The main risk factors for important reproductive health issues such as subfertility and perinatal mortality largely originate in the periconception period. To evaluate associations between modifiable maternal lifestyle factors and periconception outcomes, a systematic search was conducted for relevant studies published from 1990 to February 2017 on Embase, Medline, Web of Science, Cochrane database, PubMed and Google Scholar. The initial search identified 6166 articles, of which 49 studies were eligible for inclusion. Fecundity (the capacity to have a live birth) showed significant inverse associations with smoking, alcohol use and poor diet. Studies regarding time to pregnancy showed a decline in fecundity ratios (the monthly conception rate among exposed relative to unexposed couples) with increasing body mass index (BMI). Furthermore, risk of first-trimester miscarriage was found to be increased in smokers, alcohol and caffeine consumers, and with increasing BMI. Vitamin supplement use showed a decrease in this risk. This review demonstrates that maternal modifiable lifestyle factors affect periconception outcomes. If couples planning a pregnancy are more aware and supported to adopt healthy lifestyles during the periconceptional 'window of opportunity', short-term reproductive health as well as health in later life and even of future generations can be further improved.

The effect of a local promotional campaign on preconceptional lifestyle changes and the use of preconception care.

PURPOSE: The objective of this study was to investigate the effect of a local promotional campaign on preconceptional lifestyle changes and the use of preconception care (PCC). MATERIAL AND METHODS: This quasi-comparative study was carried out between February 2015 and February 2016 at a community midwifery practice in the Netherlands. The intervention consisted of a dual track approach (i) a promotional campaign for couples who wish to conceive and (ii) a PCC pathway for health care providers. Questionnaires were collected from a sample of women who received antenatal care during the pre-intervention (n = 283) and post-intervention (n = 257) period. Main outcome measures were preconceptional lifestyle changes and PCC use (defined as searching for information and/or consulting a health care provider). RESULTS: Women who were exposed to the intervention were significantly more likely to make at least one lifestyle change during the preconception period [adjusted OR 1.56 (95% CI 1.02-2.39)]. Women were especially more likely to preconceptionally reduce or quit [adjusted OR 1.72 (95% CI 1.05-2.83)] their alcohol consumption after exposure to the intervention. Although non-significant, it appeared that women who were exposed to the intervention more often prepared themselves for pregnancy by means of independently searching for preconception health information [adjusted OR 1.13 (95% CI 0.77-1.65)] or consulting a health care provider regarding their wish to conceive [adjusted OR 1.24 (95% CI 0.81-1.92)]. CONCLUSIONS: Exposure to a local promotional campaign targeted at preconceptional health was associated with improved preconceptional lifestyle behaviours, especially with regard to alcohol consumption, and has the potential to improve the use of PCC.

Maternal Lifestyle Impairs Embryonic Growth: The Rotterdam Periconception Cohort.

Previously, embryonic growth has been assumed to be uniform, but in recent years, it has become more clear that genetic and environmental factors may influence the intrauterine environment and therefore embryonic growth trajectories as well as pregnancy course and outcome. The objective of this study was to investigate associations between modifiable maternal nutrition and lifestyle factors during the periconception period and embryonic growth. We established a prospective cohort including 342 women less than 13 weeks pregnant. At enrollment, women filled out a questionnaire regarding demographic and medical data and a validated food frequency questionnaire. Participants received multiple 3-dimensional ultrasound examinations up until the 12th week of pregnancy, and crown-rump length (CRL) and embryonic volume (EV) were measured offline using V-Scope Virtual Reality software (version 1.0.0) in a Barco I-Space. Associations between maternal periconception vegetable and fruit intake, folic acid supplement use, smoking, and alcohol consumption and embryonic growth measurements were assessed by linear mixed models adjusted for potential confounders. No or postconception initiation of folic acid supplement use was significantly associated with a 0.76 mm (-7.8%) and 1.63 mm (-3.7%) smaller CRL and a 0.01 cm3 (-19.5%) and 0.86 cm3 (-12.2%) smaller EV at 7+0 and 11+0 weeks of gestation, respectively. Smoking, alcohol consumption, and inadequate fruit and vegetable intake showed weaker associations with embryonic growth parameters. These results emphasize the influence of periconceptional maternal folic acid supplement use on embryonic growth. Results regarding maternal nutrition and lifestyle factors also suggest an association with embryonic growth, but this has to be confirmed in a larger study.

The use of the mHealth program Smarter Pregnancy in preconception care: rationale, study design and data collection of a randomized controlled trial.

BACKGROUND: Unhealthy nutrition and lifestyle contribute to the worldwide rising prevalence of non-communicable diseases. This also accounts for the reproductive population, in which unhealthy behavior affects fertility and pregnancy outcome. Maternal smoking, alcohol consumption and inadequate folic acid supplement use are strongly associated with fetal complications as small for gestational age, premature birth and congenital malformations. In the Netherlands 83% of the perinatal mortality rate is due to these complications and is relatively high compared to other European countries. In order to reduce this prevalence rate, preconception care should be focused on the promotion of health of prospective parents by identification and intervention on modifiable nutrition and lifestyle risk factors. We developed the personal mHealth program 'Smarter Pregnancy' (Dutch version available on: https://www.slimmerzwanger.nl ) to provide individual coaching and information to improve nutrition and lifestyle during the preconception period in order to improve health of the reproductive population and subsequent generations. METHODS: Women between 18 and 45 years of age, and trying to conceive are eligible for inclusion in a randomized controlled trial. Participants are allocated either to a general population cohort or a subfertile (IVF/ICSI) population cohort. The intervention group receives personal online coaching based on the identified nutrition and lifestyle risk factors at baseline. Coaching comprises recipes, incentives, additional questions including feedback and text and e-mail messages, with a maximum of three per week. The control group only receives one recipe per week to maintain adherence to the program and prevent drop out. Screening questionnaires are send in both groups at 6, 12, 18, and 24 weeks of the program to monitor the change in the identified risk factors. DISCUSSION: We expect to demonstrate that the mHealth program 'Smarter Pregnancy' can effectively improve nutrition and lifestyle in couples contemplating pregnancy. By the identification and improvement of modifiable nutrition and lifestyle risk factors on a large scale, both reproductive and pregnancy outcomes can be improved and subsequent perinatal morbidity and mortality rates are expected to be reduced. The current use and rapid development of mHealth applications offers new opportunities to reach and educate large populations, which can facilitate the implementation of preconception care.
