The association between environmental conditions and pregnancy outcome has been under investigation for a long time, but results appear to be inconclusive regarding damage to either the newborn or the mother. The aim of this study was to evaluate the distribution of hospitalization of newborns with low birthweight (< 2500 g) and extremely low birthweight (< 1000 g) in the geographical area of Taranto, Italy, which is characterized by high environmental risk because of industrial pollution. We analyzed the database of hospital discharge forms for the years 2001–2013 regarding hospital admission of newborns in the region of Apulia. The relative risk (RR) of hospitalization, adjusted for the deprivation index, was estimated using the Besag–York–Molliè Bayesian model. The city of Taranto, which has the highest environmental risk, had the highest RR for newborns with low birthweight (1.47, 95% uncertainty interval 1.38–1.56). Other geographical areas with high environmental pollution had higher RRs for low birth weight compared with the regional average. We found no geographical distribution pattern of extremely low birthweight that would suggest an association with environmental pollution.

意大利普利亚高环境风险地区低出生体重和极低出生体重事件调查

长期以来，人们一直在研究环境条件与妊娠结果之间的关系，但结果似乎对新生儿或母亲的损害没有定论。本研究的目的是评估意大利塔兰托地理区域内低出生体重（< 2500 g）和极低出生体重（< 1000 g）新生儿住院的分布情况，该地理区域因工业而具有高环境风险。污染。我们分析了 2001-2013 年关于普利亚地区新生儿入院的出院表格数据库。使用 Besag-York-Molliè Bayesian 模型估计根据剥夺指数调整的住院相对风险 (RR)。环境风险最高的塔兰托市，低出生体重新生儿的 RR 最高（1.47，95% 不确定区间 1.38-1.56）。其他环境污染严重的地理区域与区域平均水平相比，低出生体重的 RRs 更高。我们没有发现极低出生体重的地理分布模式表明与环境污染有关。
