Studies examining the intricate interplay between poverty, female literacy, child malnutrition, and child mortality are rare in demographic literature. Given the recent focus on Millennium Development Goals 4 (child survival) and 5 (maternal health), we explored whether the geographic regions that were underprivileged in terms of wealth, female literacy, child nutrition, or safe delivery were also grappling with the elevated risk of child mortality; whether there were any spatial outliers; whether these relationships have undergone any significant change over historical time periods.
The present paper attempted to investigate these critical questions using data from household surveys like NFHS 1992-1993, NFHS 1998-1999 and DLHS 2002-2004. For the first time, we employed geo-spatial techniques like Moran's-I, univariate LISA, bivariate LISA, spatial error regression, and spatiotemporal regression to address the research problem. For carrying out the geospatial analysis, we classified India into 76 natural regions based on the agro-climatic scheme proposed by Bhat and Zavier (1999) following the Census of India Study and all estimates were generated for each of the geographic regions.
RESULT/CONCLUSIONS: This study brings out the stark intra-state and inter-regional disparities in infant and under-five mortality in India over the past two decades. It further reveals, for the first time, that geographic regions that were underprivileged in child nutrition or wealth or female literacy were also likely to be disadvantaged in terms of infant and child survival irrespective of the state to which they belong. While the role of economic status in explaining child malnutrition and child survival has weakened, the effect of mother's education has actually become stronger over time.
在人口学文献中,很少有研究考察贫困、女性识字率、儿童营养不良和儿童死亡率之间错综复杂的相互作用。鉴于最近对千年发展目标 4(儿童生存)和 5(孕产妇健康)的关注,我们探讨了在财富、女性识字率、儿童营养或安全分娩方面处于劣势的地理区域是否也面临儿童死亡率升高的风险;是否存在任何空间异常值;这些关系在历史时期是否发生了任何重大变化。
本研究试图利用来自家庭调查(如 NFHS 1992-1993、NFHS 1998-1999 和 DLHS 2002-2004)的数据来研究这些关键问题。我们首次运用地理空间技术,如 Moran's-I、单变量 LISA、双变量 LISA、空间误差回归和时空回归来解决研究问题。为了进行地理空间分析,我们根据印度人口普查研究,根据 Bhat 和 Zavier(1999 年)提出的农业气候方案,将印度分为 76 个自然区域,所有估计值都是针对每个地理区域生成的。
结果/结论:本研究揭示了过去二十年来印度在婴儿和五岁以下儿童死亡率方面存在的明显的州内和区域间差异。它还首次揭示了在儿童营养或财富或女性识字率方面处于劣势的地理区域,无论它们所属的州如何,在婴儿和儿童生存方面也可能处于劣势。虽然经济状况在解释儿童营养不良和儿童生存方面的作用已经减弱,但母亲教育的影响实际上随着时间的推移变得更强。
