An ecological study was performed to identify patterns in the spatial distribution of neonatal mortality and risk areas as well as associated factors in Salvador, Bahia State, Brazil, 2000-2006. A thematic map was constructed, and techniques were used for formal assessment of spatial dependence. No spatial and spatial regression models were used to assess possible relationships between selected factors and spatial distribution of neonatal mortality. Spatial autocorrelation was observed in neonatal mortality (I = 0.17; p = 0.0100), so its distribution was non-random. The analysis showed a spatial pattern in which the highest risk (> 9.0/1,000 live births) was concentrated in the downtown areas and peripheral neighborhoods with the highest concentration of low-income families, and this was associated with the target risk factors. The proportion of low birth weight newborns was the only variable that was significantly associated with neonatal mortality. Living conditions may have contributed to the uneven spatial distribution of neonatal mortality in this city.
开展了一项生态研究，以确定2000 - 2006年巴西巴伊亚州萨尔瓦多市新生儿死亡率的空间分布模式、风险区域以及相关因素。绘制了一幅专题地图，并运用技术手段对空间依赖性进行正式评估。未使用空间和空间回归模型来评估所选因素与新生儿死亡率空间分布之间的可能关系。观察到新生儿死亡率存在空间自相关（I = 0.17；p = 0.0100），因此其分布并非随机。分析显示出一种空间模式，即最高风险（> 9.0/1000活产）集中在市中心地区以及低收入家庭最集中的周边社区，且这与目标风险因素相关。低出生体重新生儿的比例是唯一与新生儿死亡率显著相关的变量。生活条件可能导致了该市新生儿死亡率的空间分布不均。
