Introduction: Food insecurity represents a public health issue that has been associated with poor birth outcomes. We describe the methodological steps followed to structure and validate a questionnaire, which has the potential to contribute to the planning and conduction of future studies investigating the possible association between maternal food insecurity and fetal structural anomalies. Methods: We first conducted a literature review to structure and validate the questionnaire. Subsequently, we drafted the questionnaire based on the results of this review, further refined through two focus groups. Afterward, the questionnaire was submitted using the Delphi Method to a panel of experts for validation. We conducted a pilot study prior to recruiting the final sample. Results: The questionnaire consisted of sections covering information about socio-demographic characteristics, women's health and lifestyle, pregnancy, and food security status. After the first Delphi round, the Content Validity Index (CVI) for each section ranged 0.81–0.85, while after the second round all items had a CVI of 1. The final version of the questionnaire, consisting of 87 items, was pilot tested among 20 participants. Cronbach's Alpha for each section resulted in values higher than 0.6. The response rate ranged from 78 to 100%. A situation of food security was present in 85% of the participants, while 5% were in a situation of mild food insecurity and 10% of moderate food insecurity. Conclusion: The questionnaire has appropriate measurement properties, and is an adequate instrument to evaluate the association between maternal food insecurity and fetal structural anomalies. Significance: What is already known? Food insecurity in pregnant women is a public health concern, since it affects both the woman and her child. This condition leads to poor health outcomes, such as gestational hypertension, preeclampsia, gestational diabetes, and anemia for the woman, and low birth weight, shorter gestational age, and chronic diseases in adulthood for the child. However, to date, few studies have investigated the potential association between food insecurity in women during pregnancy and fetal structural anomalies. What this study adds? To our knowledge, in Europe this is the first study to evaluate the association of interest. Understanding and assessing the potential association of food insecurity in pregnant women and fetal structural anomalies might help policymakers design and implement policies, interventions, and screening strategies to mitigate food insecurity in pregnant women. In this regard, there is the need for validated instruments, and through this study we provide the detailed methodology process in developing and structuring a questionnaire that might be used as a guide tool for future studies. Identifying women at risk of food insecurity and assisting them might help in preventing poor health outcomes and fetal structural anomalies, which could also decrease the burden on health systems.

Background While many studies focus on specific aspects of Unaccompanied Migrant Minors' (UMMs) health, especially mental well-being, there is a lack of tools comprehensively assessing their needs. To fill this gap, we developed and validated a questionnaire to thoroughly assess unAccompaniEd miGrant mInorS' physical, psychological, legal, spiritual, social and educational needs (AEGIS-Q). Methods This work consisted of three stages. The first one involved an extensive literature review. Given the results of the review, a first draft of the questionnaire was developed and submitted to a panel of experts for validation (Delphi method-second stage). During the third stage, the final version of the questionnaire was pilot-tested in a sample of 18 UMMs. Results The questionnaire, drafted based on the results of the review, consisted of sections covering personal data, migration profile, physical health needs and access to healthcare, psychological needs, legal needs, spiritual needs and educational and social needs of UMMs. After two Delphi rounds, the final version of the questionnaire, consisting of 83 questions, was structured. The pilot study had a response rate of 89–100%. We found substantial reliability for most of the sections in the questionnaire, including physical health (α=0.652), legal (α=0.781), and educational and social (α=0.614) needs. The questions regarding psychological needs had very high reliability (α=0.860). Conclusions The questionnaire offers a useful sharable tool to assess and monitor UMMs' needs, helping the reception system to better know and meet their needs and implement the taking in charge.
