UNLABELLED
Several studies have identified social inequalities in low birth weight (LBW), preterm birth (PTB), and intrauterine growth restriction (IUGR), which, in recent years, have diminished or disappeared in certain locations.
OBJECTIVES
Estimate the LBW, PTB, and IUGR rates in São Luís, Maranhão, Brazil, in 2010, and check for associations between socioeconomic factors and these indicators.
METHODS
This study is based on a birth cohort performed in São Luís. 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 São Luís.
未标注
多项研究已确定低出生体重（LBW）、早产（PTB）和宫内生长受限（IUGR）方面存在社会不平等现象，近年来，某些地区此类现象已有所减少或消失。
目的
估算2010年巴西马拉尼昂州圣路易斯市的低出生体重、早产和宫内生长受限发生率，并检验社会经济因素与这些指标之间的关联。
方法
本研究基于在圣路易斯市开展的一项出生队列研究。纳入了2010年在该市医院出生的5051例单胎新生儿。采用卡方检验进行比例比较，同时使用具有稳健误差方差的简单和多重泊松回归模型来估算相对风险。
结果
低出生体重、早产和宫内生长受限发生率分别为7.5%、12.2%和10.3%。低收入家庭的低出生体重发生率较高，而早产和宫内生长受限与社会经济因素无关。
结论
这些指标与社会不平等现象不存在关联或关联较弱，表明圣路易斯市的医疗保健和/或社会状况有所改善。
