The objectives were to establish regions by level of maternal mortality in order to evaluate its trend from 1937-1995 and to analyze characteristics of cases which occurred from 1990-1995.
Regionalization of the country by maternal mortality level was carried out using Poisson regression. Level and mortality trends were analyzed globally and compared by regions using Poisson and linear regression. Characteristics of cases were analyzed from 1990-1995 using proportions and X2 test.
Four well-differentiated and independent regions were established. Low and medium maternal mortality rate regions were found in northern and northwestern Mexico. High and very high maternal mortality regions were found in the South and the Southeast of the country. Even when maternal mortality had descended, the speed of the descent has decreased and in the last few years, maternal mortality has increased. The quality of health care is a challenge for regions with low mortality rates, while the problem of accessibility is present in those with very high mortality rates.
The employment of this regionalization approach in maternal mortality analysis would be useful to determine specific problems for each region. The establishment of programs according to this analysis could contribute to decrease in maternal mortality cases in Mexico.
目的是按孕产妇死亡率水平划分区域，以评估1937年至1995年期间的趋势，并分析1990年至1995年期间发生病例的特征。
采用泊松回归按孕产妇死亡率水平对该国进行区域划分。使用泊松回归和线性回归对全球的水平和死亡率趋势进行分析，并按区域进行比较。使用比例和卡方检验分析1990年至1995年期间病例的特征。
确定了四个区分明显且相互独立的区域。墨西哥北部和西北部为孕产妇死亡率低和中等的区域。该国南部和东南部为孕产妇死亡率高和非常高的区域。即使孕产妇死亡率有所下降，下降速度也已减缓，并且在过去几年中，孕产妇死亡率有所上升。医疗保健质量对低死亡率地区而言是一项挑战，而可及性问题则存在于死亡率非常高的地区。
在孕产妇死亡率分析中采用这种区域划分方法将有助于确定每个区域的具体问题。根据该分析制定方案有助于减少墨西哥的孕产妇死亡病例。
