The association of biomass fuel use with body weight has never been investigated. We therefore examined the effect of biomass fuel use on body weight of adult Ghanaian women. Data from the 2014 Ghana Demographic and Health Survey, a nationally representative population-based survey was analysed for this study. A total of 4751 women who had anthropometric (height and weight) data qualified for inclusion in this study. In linear regression modelling, charcoal use resulted in 3.08 kg (95% CI: 2.04, 4.12) and 0.81 kg/m (95%CI: 0.29, 1.33) reduction in weight and body mass index (BMI), respectively, compared to clean fuel (electricity, liquefied petroleum gas and natural gas) use. Use of wood resulted in much higher reduction in weight and BMI. In modified Poisson regression, charcoal users had 19% (Adjusted Prevalence Ratio [aPR] = 0.81; 95%CI: 0.71, 0.92) and 29% (aPR = 0.71; 95%CI: 0.61, 0.83) decreased risk of overweight and obesity, respectively, compared to clean fuel users. Wood users had much higher decreased risk of overweight and obesity. In conclusion, biomass fuel use was associated with reduced body weight and BMI of Ghanaian women and is the first report on the relationship. However, it is important that our findings are confirmed and the biological mechanisms elucidated through rigorous study designs.
生物量燃料的使用与体重的关联从未被研究过。因此，我们研究了生物量燃料的使用对加纳成年女性体重的影响。本研究分析了 2014 年加纳人口与健康调查的数据，该调查是一项具有全国代表性的基于人群的调查。共有 4751 名具有人体测量（身高和体重）数据的女性符合纳入本研究的条件。在线性回归模型中，与使用清洁燃料（电、液化石油气和天然气）相比，使用木炭分别导致体重和体重指数（BMI）降低 3.08 公斤（95%CI：2.04，4.12）和 0.81 公斤/米（95%CI：0.29，1.33）。与使用木材相比，使用木炭导致体重和 BMI 的降低幅度要大得多。在修正泊松回归中，与使用清洁燃料相比，木炭使用者超重和肥胖的风险分别降低了 19%（调整后的患病率比[aPR] = 0.81；95%CI：0.71，0.92）和 29%（aPR = 0.71；95%CI：0.61，0.83）。与使用清洁燃料相比，使用木材的人超重和肥胖的风险降低幅度更高。总之，生物量燃料的使用与加纳女性的体重和 BMI 降低有关，这是首次对此关系的报告。然而，通过严格的研究设计来证实我们的发现并阐明生物学机制非常重要。
