“…Birthweights obtained by maternal recall may have been subject to recall bias, but this was reduced by limiting the data collection period to births within the last five years. Although there was no evidence of an effect in our study and the reference cooking fuel differs to that of other studies, they are similar to those obtained in single-country analyses investigating the difference between biomass and cleaner fuels in Malawi (AOR, 1.29 (95% CI: 0.34; 4.48) [ 18 ]), Ethiopia (AOR, 1.3 (95% 0.9–1.9) [ 20 ]), Nigeria (−0.09 (95% CI: −0.31, 0.10) [ 17 ]), Bangladesh (AOR 0.96 (95% CI: 0.81–1.13) [ 46 ]), and India (AOR: 1.07(95% CI: 0.94–1.22) [ 47 ]). On the contrary, findings in this study were inconsistent with the population-based study from Zimbabwe which showed biomass fuel use was associated with a 175 g lower birthweight (95% CI: −300 to −50 g) [ 22 ].…”

“…However, only a limited number of studies from Africa were included in the meta-analyses [ 4 , 7 , 11 , 12 ], a region with a high burden of LBW [ 10 ], and predominant use of polluting fuels [ 1 ]. The studies from Africa were limited to relatively few countries, including Ghana [ 13 ], Nigeria [ 14 , 15 , 16 , 17 ], Malawi [ 18 ], Ethiopia [ 19 , 20 , 21 ], and Zimbabwe [ 22 ]. The African studies were limited to hospital-based settings [ 21 ] with a reliance on the woman’s subjective recall of the birth weight or size of the child [ 14 , 18 , 22 ].…”

In utero exposure to household air pollution (HAP) from polluting cooking fuels has been linked to adverse pregnancy outcomes including low birthweight (LBW). No previous study in Uganda has attempted to investigate the association between the different types of biomass cooking fuels and LBW. This study was conducted to investigate the association between wood and other biomass cooking fuel use with increased risk of LBW, using the 2016 Uganda Demographic and Health Survey for 15,270 live births within five years prior to interview. LBW, defined as birthweight of <2500 g, was estimated from maternal recall and health cards. Association between household exposure to the different solid biomass cooking fuels and LBW was determined using multivariable logistic regression. Biomass cooking fuels were used in 99.6% of the households, with few (0.3%) using cleaner fuels and 0.1% with no cooking, while the prevalence of LBW was 9.6% of all live-births. Although the crude analysis suggested an association between wood fuel use and LBW compared to other biomass and kerosene fuel use (AOR: 0.82; 95% CI: 0.67–1.00), after adjusting for socio-demographic and obstetric factors, no association was observed (AOR: 0.94; 95% CI: 0.72–1.22). LBW was significantly more likely among female neonates (AOR: 1.32 (95% CI: 1.13–1.55) and neonates born to mothers living in larger households (AOR: 1.03; 95% CI: 1.00–1.07). LBW was significantly less likely among neonates delivered at term (AOR: 0.39; 95% CI: 0.31–0.49), born to women with secondary or tertiary level of education (AOR: 0.80; 95% CI: 0.64–1.00), living in households with a higher wealth index (AOR: 0.69; 95% CI: 0.50–0.96), Eastern (AOR: 0.76; 95% CI:0.59–0.98) and Northern (AOR: 0.75; 95% CI: 0.57–0.99) regions. The study findings suggest inconclusive evidence regarding the association between the use of wood compared to other biomass and kerosene cooking fuels and risk of LBW. Given the close observed association between socioeconomic status and LBW, the Ugandan government should prioritize public health actions which support female education and broader sustainable development to improve household living standards in this setting.

“…Since then, many new studies have been conducted, focusing on a broader range of fuel types and adverse birth outcomes, and the conclusion is still inconsistent. One cohort study (27), two case-control studies (28,29), and six cross-sectional studies (30-35) suggested that polluting fuel use was related to increased risk of adverse birth outcomes, while other studies (23,24,(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47) failed to reveal a significant correlation between them. A recent review of the subject qualitatively assessed the impact of unclean cooking fuels on adverse birth outcomes, but the review was short of quantitative combined research data (48).…”

Background and aimThe current study aimed to clarify the association between household polluting cooking fuels and adverse birth outcomes using previously published articles.MethodsIn this systematic review and meta-analysis, a systematic literature search in PubMed, Embase, Web of Science, and Scopus databases were undertaken for relevant studies that had been published from inception to 16 January 2023. We calculated the overall odds ratio (OR) and 95% confidence interval (CI) for adverse birth outcomes [low birth weight (LBW), small for gestational age (SGA), stillbirth, and preterm birth (PTB)] associated with polluting cooking fuels (biomass, coal, and kerosene). Subgroup analysis and meta-regression were also conducted.ResultsWe included 16 cross-sectional, five case–control, and 11 cohort studies in the review. Polluting cooking fuels were found to be associated with LBW (OR: 1.37, 95% CI: 1.24, 1.52), SGA (OR: 1.48, 95% CI: 1.13, 1.94), stillbirth (OR: 1.38, 95% CI: 1.23, 1.55), and PTB (OR: 1.27, 95% CI: 1.19, 1.36). The results of most of the subgroup analyses were consistent with the main results. In the meta-regression of LBW, study design (cohort study: P < 0.01; cross-sectional study: P < 0.01) and sample size (≥ 1000: P < 0.01) were the covariates associated with heterogeneity. Cooking fuel types (mixed fuel: P < 0.05) were the potentially heterogeneous source in the SGA analysis.ConclusionThe use of household polluting cooking fuels could be associated with LBW, SGA, stillbirth, and PTB. The limited literature, observational study design, exposure and outcome assessment, and residual confounding suggest that further strong epidemiological evidence with improved and standardized data was required to assess health risks from particular fuels and technologies utilized.

“…9 10 Studies have linked cooking solid fuel use with adverse birth outcomes such as low birth weight (LBW), birth size, preterm birth, stillbirth, small for gestational age (SGA), Apgar score and neonatal mortality. [11][12][13][14][15][16][17][18][19][20][21][22][23] Most of previous studies have focused mainly on the association between the use of solid fuels and birth outcomes by comparing pollution fuels (wood, crop residue, animal dung, charcoal or kerosene) versus cleaner fuels (liquid petroleum gas, natural gas and/or electricity). 12 14-17 19-23 However, to our knowledge, no studies have accessed the type of cooking biomass fuels (crop residues vs fuelwood, also called 'firewood') in association with newborn birth outcomes such as birth size and LBW, even though the pollution exposure from biomass was different by type of cooking biomass fuels.…”

ObjectivesWe aimed to investigate the association between type of cooking biomass fuels (crop residues vs fuelwood) and newborn birth outcomes in Bangladeshi children.MethodsIn this birth cohort study, pregnant women who were 18 years or older with ultrasound confirmed singleton pregnancy of ≤16 weeks of gestation were enrolled from two Bangladesh clinics between January 2008 and June 2011. Exposure to cooking biomass fuels during pregnancy was assessed by an administered questionnaire. The newborn size metrics were measured at the time of delivery. We used multiple linear regression and logistic regression to assess the associations between the type of cooking biomass fuels and birth outcomes after adjusting for covariates.ResultsA total of 1137 participants were using biomass fuels, including crop residues (30.3%) and fuelwood (69.7%), respectively, for cooking. After adjusting for covariates, the use of crop residues for cooking was associated with a 0.13 SD decrease in birth length (95% CI 0.25 to −0.01), a 0.14 SD decrease in head circumference (95% CI −0.27 to –0.02), and increased risk of low birth weight (LBW, OR 1.52, 95% CI 1.07 to 2.15) compared with the use of fuelwood.ConclusionThe use of crop residues for cooking was associated with reduced birth size and increased risk for LBW in Bangladeshi children, implying that the use of crop residues during pregnancy may have a detrimental effect on fetal growth.
