We examine the effects of mother's characteristics and socioeconomic condition on weight at birth and preterm delivery in an Italian region (Umbria).
The study concerns all live-born singleton infants in 2007 with at least a gestational age of 22 weeks. Information derived from the Standard Certificate of Live Birth was linked to information from census statistics, so as to obtain a deprivation index.
On the basis of the fitting of two separate logistic regression models, we conclude that all individual socioeconomic factors are strongly associated with the outcomes at birth, apart from the deprivation index. Older and less educated mothers, and those with lower occupational level, have a higher probability to run into preterm delivery with respect to the other mothers. The relative risk ratios for low birth weight are significantly higher for older mothers, non-European, and not married. Lower weight rates are found in infants from complicated pregnancy and non-spontaneous conception.
Effects of mother's characteristics on weight at birth and weeks of gestation are confirmed. The deprivation index does not affect these outcomes, showing the proper implementation of the Health System.
我们研究了意大利翁布里亚地区（Umbria）母亲特征和社会经济状况对出生体重和早产的影响。
本研究涉及 2007 年所有至少 22 周妊娠期的单胎活产婴儿。从标准出生证明中获得的信息与人口普查统计数据相关联，以获得剥夺指数。
根据两个单独的逻辑回归模型的拟合，我们得出结论，除剥夺指数外，所有个体社会经济因素都与出生结局密切相关。与其他母亲相比，年龄较大、受教育程度较低、职业水平较低的母亲更有可能早产。对于年龄较大、非欧洲和未婚的母亲，低出生体重的相对风险比显著更高。在复杂妊娠和非自然受孕的婴儿中，体重较低的情况更为常见。
母亲特征对出生体重和妊娠期周数的影响得到了证实。剥夺指数并不影响这些结果，这表明卫生系统得到了妥善实施。
