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/m² (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.

从未研究过生物质燃料使用与体重之间的关系。因此，我们检查了使用生物质燃料对成年加纳妇女体重的影响。本研究分析了2014年加纳人口与健康调查的数据，这是一项全国性的以人口为基础的调查。共有4751名具有人体测量数据（身高和体重）的妇女有资格纳入本研究。在线性回归建模中，使用木炭可产生3.08千克（95％CI：2.04、4.12）和0.81千克/米^2。与清洁燃料（电力，液化石油气和天然气）相比，体重和体重指数（BMI）分别降低了（95％CI：0.29、1.33）。木材的使用导致重量和BMI大大降低。在改良的Poisson回归中，木炭使用者的超重和肥胖风险降低了19％（调整后患病率[aPR] = 0.81； 95％CI：0.71、0.92）和29％（aPR = 0.71； 95％CI：0.61、0.83）分别与清洁燃料使用者进行比较。木材使用者的超重和肥胖风险降低得多。总之，使用生物质燃料与加纳妇女体重减轻和BMI降低有关，这是有关这种关系的第一份报告。然而，重要的是要通过严格的研究设计确认我们的发现并阐明其生物学机制。
