Such habits include an adequate eating pattern along with good adherence to the intake of certain supplements, practice of moderate physical activity and avoiding the consumption of toxic products such as tobacco and alcohol. The objective of this study is to assess the interrelation between such habits and their association with sociodemographic variables. To such end, a cross-sectional study was conducted with a representative sample of pregnant women who attended the scheduled morphology echography consultation at the 20th gestational week in their reference public hospital in the city of Seville (Spain). Results: Younger pregnant women and with lower educational levels are the ones that present the worst eating habits and the highest smoking rate. Pregnant women with lower educational levels are the least active. Non-smoking pregnant women present better eating habits than those who smoke. Pregnant women with lower educational levels are those who accumulate more unhealthy habits during pregnancy. This should be taken into account when planning the health care provided to pregnant women and in public health intersectoral policies.<\/jats:p>","DOI":"10.3390\/nu14030557","type":"journal-article","created":{"date-parts":[[2022,1,27]],"date-time":"2022-01-27T22:00:56Z","timestamp":1643320856000},"page":"557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Relationship between Eating Habits, Physical Activity and Tobacco and Alcohol Use in Pregnant Women: Sociodemographic Inequalities"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6317-2668","authenticated-orcid":false,"given":"Isabel","family":"Corrales-Gutierrez","sequence":"first","affiliation":[{"name":"Foetal Medicine Unit, University Hospital Virgen Macarena, 41009 Seville, Spain"},{"name":"Department of Surgery, University of Seville, 41009 Seville, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisca","family":"Baena-Antequera","sequence":"additional","affiliation":[{"name":"Obstetric Unit, University Hospital Virgen de Valme, 41014 Seville, Spain"},{"name":"Nursing Department, Osuna\u2019s University School, 41640 Osuna, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4651-0439","authenticated-orcid":false,"given":"Diego","family":"Gomez-Baya","sequence":"additional","affiliation":[{"name":"Research Group on Health Promotion and Development of Lifestyle across the Life Span, University of Huelva, 21007 Huelva, Spain"},{"name":"Department of Social, Developmental and Educational Psychology, University of Huelva, 21007 Huelva, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9475-0440","authenticated-orcid":false,"given":"Fatima","family":"Leon-Larios","sequence":"additional","affiliation":[{"name":"Nursing Department, Faculty of Nursing, Physiotherapy and Podiatry, University of Seville, 41009 Seville, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramon","family":"Mendoza","sequence":"additional","affiliation":[{"name":"Research Group on Health Promotion and Development of Lifestyle across the Life Span, University of Huelva, 21007 Huelva, Spain"},{"name":"Department of Social, Developmental and Educational Psychology, University of Huelva, 21007 Huelva, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1830","DOI":"10.1016\/S0140-6736(18)30311-8","article-title":"Before the beginning: Nutrition and lifestyle in the preconception period and its importance for future health","volume":"391","author":"Stephenson","year":"2018","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/j.reprotox.2018.05.004","article-title":"Folic acid and primary prevention of neural tube defects: A review","volume":"80","author":"Hirche","year":"2018","journal-title":"Reprod.
