The effect of a locally tailored intervention on the uptake of preconception care in the Netherlands: a stepped-wedge cluster randomized trial (APROPOS-II study).

BACKGROUND: The preconception period provides a window of opportunity for interventions aiming to reduce unhealthy lifestyle behaviours and their negative effect on pregnancy outcomes. This study aimed to assess the effectiveness of a locally tailored preconception care (PCC) intervention in a hybrid-II effectiveness implementation design. METHODS: A stepped-wedge cluster randomized controlled trial was performed in four Dutch municipalities. The intervention contained a social marketing strategy aiming to improve the uptake (prospective parents) and the provision (healthcare providers) of PCC. Prospective parents participated by administering a questionnaire in early pregnancy recalling their preconceptional behaviours. Experiences of healthcare providers were also evaluated through questionnaires. The composite primary outcome was adherence to at least three out of four preconceptional lifestyle recommendations (early initiation of folic acid supplements, healthy nutrition, no smoking or alcohol use). Secondary outcomes were preconceptional lifestyle behaviour change, (online) reach of the intervention and improved knowledge among healthcare providers. RESULTS: A total of 850 women and 154 men participated in the control phase and 213 women and 39 men in the intervention phase. The composite primary outcome significantly improved among women participating in the municipality where the reach of the intervention was highest (Relative Risk (RR) 1.57 (95% Confidence Interval (CI) 1.11-2.22). Among women, vegetable intake had significantly improved in the intervention phase (RR 1.82 (95%CI 1.14-2.91)). The aimed online reach- and engagement rate of the intervention was achieved most of the time. Also, after the intervention, more healthcare providers were aware of PCC-risk factors (54.5% vs. 47.7%; p = 0.040) and more healthcare providers considered it easier to start a conversation about PCC (75.0% vs. 47.9%; p = 0.030). CONCLUSION: The intervention showed some tentative positive effects on lifestyle behaviours among prospective parents. Primarily on vegetable intake and the knowledge and competence of healthcare providers. The results of this study contribute to the evidence regarding successfully implementing PCC-interventions to optimize the health of prospective parents and future generations.

Validation of an internet questionnaire for risk assessment in preconception care.

AIM: Validation of a self-administered Internet questionnaire for preconception risk assessment. METHODS: Women with an appointment at the outpatient clinics for preconception care or fertility at the Erasmus Medical Center Rotterdam were requested to fill out the online questionnaire prior to attendance. Subsequently, the items of the questionnaire were verified by history taking during the first or next appointment. Agreement between the 2 screening methods (Internet vs. history taking) was calculated using Kappa statistic. RESULTS: Most lifestyle variables, including smoking, alcohol, and dietary items, showed a good to high level of agreement when compared to the interview. Most medical history and obstetric history items also showed a good to high level of agreement. The use of over-the-counter drugs revealed a poor level of agreement (Kappa = 0.21). The items pertaining to women's family history showed a reasonable level of agreement; however, the partner's family history was unreliable and should be checked at the interview. CONCLUSION: The online questionnaire www.zwangerwijzer.nl is a useful tool for the identification of a number of potential risk factors in the preconception care setting and was found to be a an efficient and clear screening instrument by the majority of women. However, additional history taking by trained professionals is necessary to verify several items and to further explore identified risk factors for an adverse pregnancy outcome.

[Preconception care: an essential part of the care for mother and child]. / Preconceptiezorg: een onlosmakelijk onderdeel van de zorg voor moeder en kind.

Despite the modernisation of antenatal care in the Western world, the incidence of a number of adverse pregnancy outcomes, such as birth defects, low birth weight and preterm birth, has not decreased over the past few decades. Since its inception at the beginning of the last century, the concept of antenatal care has not changed. The first antenatal visit typically starts at the end of the first trimester. By this stage of pregnancy organogenesis and early placentation have been completed making it almost impossible to reverse any unfavourable exposure on the foetus. Preconception care addresses risk factors that are present prior to pregnancy. By either eliminating or altering risk factors during this period, pregnancy outcome may improve. The goal of preconception care is to optimise the quality of foetal, newborn and infant life through primary prevention. With regard to genetic conditions the aims of preconception care are more nuanced. The principle components of preconception care include (a) risk assessment, (b) information and advice on health promotion, (c) specific counselling and (d) intervention. The effectiveness of preconception care has been demonstrated in women who are at increased risk of adverse pregnancy outcome. In women at low-risk, however, the usefulness of preconception care has yet to be established. The concept of preconception care is relatively simple, logical and promises much. For preconception care to be a success, it is crucial to make this form of preventive care available to all prospective parents. The Internet could play a major part in the dissemination of information that is relevant to a successful outcome of pregnancy.
