We studied secular stillbirth trends by maternal socioeconomic status (SES) in Spain.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>We developed a population-based observational study, including 4 083 919 births during 2007\u201315. We estimate stillbirth rates and secular trends by maternal SES. We also evaluated the joint effect of maternal educational attainment and the Human Development Index (HDI) of women\u2019s country of origin on the risk of stillbirth.

Overall, women from countries with low HDIs and low educational attainments had approximately a four times higher risk of stillbirth (RR: 4.44; 95%CI: 3.71\u20135.32). Furthermore, we found a paradoxical reduction of the stillbirth gap over time between the highest and the lowest SESs, which is mostly due to the significant and increasing trend of stillbirth risk among highly educated women of advanced maternal age.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Our findings highlight no improvement in stillbirth rates among women of lower SES and an increasing trend among highly educated women of advanced maternal age over recent years. Public health policies developing preventive programmes to reduce stillbirth rates among women with lower SES are needed as well as the necessity of further study to understand the growing trend of age-related stillbirths among highly educated women in Spain.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/eurpub\/ckz086","type":"journal-article","created":{"date-parts":[[2019,4,30]],"date-time":"2019-04-30T14:49:02Z","timestamp":1556635742000},"page":"1043-1048","source":"Crossref","is-referenced-by-count":17,"title":["Secular trends in stillbirth by maternal socioeconomic status in Spain 2007\u201315: a population-based study of 4 million births"],"prefix":"10.1093","volume":"29","author":[{"given":"Miguel Angel","family":"Luque-Fernandez","sequence":"first","affiliation":[{"name":"Andalusian School of Public Health, Biomedical Research Institute of Granada, University of Granada, Granada, Spain"},{"name":"Department of Epidemiology and Population Health, London School of Hygiene and Tropical Medicine, London, UK"},{"name":"Department of Epidemiology, Harvard T.H.
