While the importance of antenatal care for maternal and child health continues to be debated, several researchers have documented its impact on intermediate variables affecting survival such as birth weight. These studies have also highlighted the problems of causality that are typically not taken into account when estimating the effects of antenatal care on skilled birth attendance. In this study, we revisit this relation in the rural areas of four countries: Ghana, Kenya, Uganda and Tanzania. Using a structural equation modeling approach that corrects for endogeneity, in all four countries we find that the usual simpler probit (or logit) models tend to underestimate the direct effect of antenatal care on skilled birth attendance. Furthermore, in two of the countries, this estimated effect is mediated by the range of services offered to women during antenatal care. These results suggest that governments and NGOs should place more importance on the role of antenatal care providers and on the services they offer, in efforts to promote skilled birth attendance.
虽然产前护理对母婴健康的重要性仍存在争议,但已有几位研究人员记录了其对影响生存的中间变量(如出生体重)的影响。这些研究还强调了通常在估计产前护理对熟练接生的影响时未考虑到的因果关系问题。在这项研究中,我们在加纳、肯尼亚、乌干达和坦桑尼亚这四个国家的农村地区重新探讨了这一关系。我们使用一种结构方程建模方法来纠正内生性,在所有四个国家中,我们发现通常更简单的概率单位(或对数单位)模型往往会低估产前护理对熟练接生的直接影响。此外,在其中两个国家,这种估计的影响是由产前护理期间向妇女提供的服务范围所介导的。这些结果表明,政府和非政府组织应该更加重视产前护理提供者的作用及其提供的服务,以努力促进熟练接生。
