This study examined the impact of wood fuel consumption on health outcomes, specifically under-five and adult mortality in Sub-Saharan Africa, where wood usage for cooking and heating is on the increase. Generalized method of moment (GMM) estimators were used to estimate the impact of wood fuel consumption on under-five and adult mortality (and also male and female mortality) in the region. The findings revealed that wood fuel consumption had significant positive impact on under-five and adult mortality. It suggests that over the studied period, an increase in wood fuel consumption has increased the mortality of under-five and adult. Importantly, it indicated that the magnitude of the effect of wood fuel consumption was more on the under-five than the adults. Similarly, assessing the effect on a gender basis, it was revealed that the effect was more on female than male adults. This finding suggests that the resultant mortality from wood smoke related infections is more on under-five children than adults, and also are more on female adults than male adults. We, therefore, recommended that an alternative affordable, clean energy source for cooking and heating should be provided to reduce the wood fuel consumption.
本研究考察了木材燃料消耗对健康结果的影响，特别是对撒哈拉以南非洲地区五岁以下儿童和成年人死亡率的影响，该地区用于烹饪和取暖的木材使用量正在增加。采用广义矩估计法（GMM）来估计该地区木材燃料消耗对五岁以下儿童和成年人死亡率（以及男性和女性死亡率）的影响。研究结果显示，木材燃料消耗对五岁以下儿童和成年人死亡率有显著的正向影响。这表明在研究期间，木材燃料消耗的增加提高了五岁以下儿童和成年人的死亡率。重要的是，研究表明木材燃料消耗对五岁以下儿童的影响程度大于成年人。同样，按性别评估影响时发现，对成年女性的影响大于成年男性。这一发现表明，与木材烟雾相关感染导致的死亡率在五岁以下儿童中高于成年人，在成年女性中也高于成年男性。因此，我们建议应提供一种替代的、价格可承受的清洁能源用于烹饪和取暖，以减少木材燃料的消耗。
