Abstract：
As the largest profession within the healthcare industry, nursing and midwifery workforce (NMW) provides comprehensive healthcare to children and their families. This study quantified the independent role of NMW in reducing under-5 mortality rate (U5MR) worldwide.
A retrospective, observational and correlational study to examine the independent role of NMW in protecting against U5MR.
Within 266 \"countries\", the cross-sectional correlations between NMW and U5MR were examined with scatter plots, Pearson\'s r, nonparametric, partial correlation and multiple regression. The affluence, education and urban advantages were considered as the potential competing factors for the NMW-U5MR relationship. The NMW-U5MR correlations in both developing and developed countries were explored and compared.
Bivariate correlations revealed that NMW negatively and significantly correlated to U5MR worldwide. When the contributing effects of economic affluence, urbanization and education were removed, the independent NMW role in reducing U5MR remained significant. NMW independently explained 9.36% U5MR variance. Multilinear regression selected NMW as a significant factor contributing an extra 3% of explanation to U5MR variance when NMW, affluence, education and urban advantage were incorporated as the predicting variables. NMW correlated with U5MR significantly more strongly in developing countries than in developed countries.
NMW, indexing nursing and midwifery service, was a significant factor for reducing U5MR worldwide. This beneficial effect explained 9.36% of U5MR variance which was independent of economic affluence, urbanization and education. The NMW may be a more significant risk factor for protecting children from dying under 5 years old in developing countries. As a strategic response to the advocacy of the United Nations to reduce child mortality, it is worthy for health authorities to consider a further extension of nurses and midwives\' practice scope to enable communities to have more access to NMW healthcare services.

摘要：
背景：作为医疗保健行业中最大的职业，护理和助产劳动力（NMW）为儿童及其家庭提供全面的医疗保健。这项研究量化了NMW在降低全球5岁以下儿童死亡率（U5MR）中的独立作用。
方法：回顾性研究，观察性和相关性研究，以检查NMW在预防U5MR中的独立作用。
方法：在266个国家/地区内，用散点图检查了NMW和U5MR之间的横截面相关性，皮尔森的r，非参数，偏相关和多元回归。富裕，教育和城市优势被认为是NMW-U5MR关系的潜在竞争因素。探索并比较了发展中国家和发达国家的NMW-U5MR相关性。
结果：双变量相关性显示，NMW与全球U5MR呈显著负相关。当经济富裕的贡献效应，城市化和教育被取消，在降低U5MR中的独立NMW作用仍然显著.NMW独立解释了9.36%的U5MR方差。当NMW，富裕,教育和城市优势被纳入预测变量。在发展中国家，NMW与U5MR的相关性明显高于发达国家。
结论：NMW，索引护理和助产服务，是全球降低U5MR的重要因素。这一有益效应解释了9.36%的U5MR方差，这与经济富裕程度无关，城市化和教育。在发展中国家，NMW可能是保护5岁以下儿童免于死亡的更重要的风险因素。作为对联合国倡导降低儿童死亡率的战略回应，卫生当局值得考虑进一步扩大护士和助产士的执业范围，以使社区有更多机会获得NMW医疗保健服务。
