Therefore, the objective of this study was to determine the association between maternal age and different newborn health parameters. An observational study was conducted in Spain on primiparous women and their infants. Data were collected on newborn health variables, breastfeeding, and different clinical practices that are beneficial for child health and development. Crude and adjusted mean differences were calculated along with the standard error of the mean. A total of 373 women and their children participated. In terms of early commencement skin-to-skin contact, the mean age of women that did skin-to-skin contact was 29.95 \u00b1 0.31 years compared to 31.49 \u00b1 0.66 years in those that did not (p = 0.042). In terms of other newborn parameters, such as preterm birth, health problems or complications, or the need for hospital admission, these were more frequent in the oldest group of mothers, but the differences found were not significant (p &gt; 0.05). Hence, indicators of newborn morbidity were not found to be significantly associated with maternal age; however, beneficial practices such as early commencement skin-to-skin contact were found to be significantly associated with maternal age.<\/jats:p>","DOI":"10.3390\/ijerph16183448","type":"journal-article","created":{"date-parts":[[2019,9,17]],"date-time":"2019-09-17T04:23:36Z","timestamp":1568694216000},"page":"3448","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Newborn Health Indicators Associated with Maternal Age during First Pregnancy"],"prefix":"10.3390","volume":"16","author":[{"given":"Leticia","family":"Molina-Garc\u00eda","sequence":"first","affiliation":[{"name":"Complejo Hospitalario de Ja\u00e9n, 23007 Ja\u00e9n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel","family":"Hidalgo-Ruiz","sequence":"additional","affiliation":[{"name":"Hospital San Juan de la Cruz, 23400 \u00dabeda, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Mar\u00eda","family":"C\u00e1mara-Jurado","sequence":"additional","affiliation":[{"name":"Hospital San Agust\u00edn, 23700 Linares, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Jose","family":"Fern\u00e1ndez-Valero","sequence":"additional","affiliation":[{"name":"Complejo Hospitalario de Ja\u00e9n, 23007 Ja\u00e9n, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Delgado-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, University of Jaen, 23071 Jaen, Spain"},{"name":"Consortium for Biomedical Research in Epidemiology and Public Health (CIBERESP), 28029 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Miguel","family":"Mart\u00ednez-Galiano","sequence":"additional","affiliation":[{"name":"Consortium for Biomedical Research in Epidemiology and Public Health (CIBERESP), 28029 Madrid, Spain"},{"name":"Department of Nursing, Campus de Las Lagunillas s\/n, Edificio B3, University of Jaen, 23071 Jaen, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"311","DOI":"10.1080\/00324728.2012.697569","article-title":"Fertility postponement is largely due to rising educational enrolment","volume":"66","author":"Beaujouan","year":"2012","journal-title":"Popul.
