Objectives: Estimate the LBW, PTB, and IUGR rates in S\u00e3o Lu\u00eds, Maranh\u00e3o, Brazil, in 2010, and check for associations between socioeconomic factors and these indicators. Methods: This study is based on a birth cohort performed in S\u00e3o Lu\u00eds. It included 5,051 singleton hospital births in 2010. The chi-square test was used for proportion comparisons, while simple and multiple Poisson regression models with robust error variance were used to estimate relative risks. Results: LBW, PTB and IUGR rates were 7.5, 12.2, and 10.3% respectively. LBW was higher in low-income families, while PTB and IUGR were not associated with socioeconomic factors. Conclusion: The absence or weak association of these indicators with social inequality point to improvements in health care and\/or in social conditions in S\u00e3o Lu\u00eds.<\/jats:p>","DOI":"10.1590\/1980-5497201700040010","type":"journal-article","created":{"date-parts":[[2017,12,16]],"date-time":"2017-12-16T22:47:46Z","timestamp":1513464466000},"page":"676-687","source":"Crossref","is-referenced-by-count":6,"title":["Maternal
