The Impact of Using Clean Fuel on the Risk of Stunting in Children Aged 0-59 Months

Stunting is a critical global health challenge, particularly in developing nations, affecting children's physical, cognitive, and socioeconomic outcomes. This study investigates the impact of clean cooking fuel use on stunting risk among children aged 0–59 months in Indonesia, employing cross-sectional data from the 2014 Indonesian Family Life Survey (IFLS) and the Propensity Score Matching (PSM) method. The results reveal that households using clean cooking fuels, such as liquefied petroleum gas (LPG), significantly improve children's Height-for-Age Z-scores, reducing stunting risk. Factors including higher household education, income levels, and access to urban areas positively influence clean fuel adoption. The study underscores the importance of clean energy policies and increased awareness, particularly in rural areas, to mitigate health disparities and improve childhood growth outcomes. These findings contribute to the growing evidence linking clean energy transitions with enhanced public health and child development indicators.

Household fuel use and the regression from prehypertension to normotension among Chinese middle-aged and older adults: a cohort study.

To examine the association of household fuel use with prehypertension regression among middle-aged and older people based on the China Health and Retirement Longitudinal Study (CHARLS), we included a total of 3501 participants with prehypertension at baseline, and they were followed up from 2011-2012 to 2015-2016 with information on blood pressure and household solid fuel use (heating and cooking fuels). Cox proportional hazards regression models were used to explore the hazard ratio (HR) and 95% confidence interval (CI) between fuel use and prehypertension regression. Additionally, we investigated the impact of switching fuels (2011-2013) on the regression to normotension during the 4-year follow-up. Linear regression was used to examine the effect of household fuel use on changes in blood pressure. Compared to solid fuel users, those who used clean fuel for heating at baseline had a positive effect on the regression of prehypertension (HR: 1.28, 95% CI: 1.08-1.53). Participants who used clean fuels for both heating and cooking had increased odds for the regression of prehypertension (HR: 1.32, 95% CI: 1.09-1.60). Compared to consistent solid fuel users, those who consistently used clean fuel for heating had a higher likelihood of transitioning from prehypertension to normotension (HR: 1.36, 95% CI: 1.06-1.73) and exhibited 2.45 mmHg lower systolic blood pressure. In conclusion, household clean fuel use for heating was positively associated with the regression of prehypertension to normotension. Furthermore, switching from solid fuel to clean fuel for heating could reduce the risk of prehypertension in Chinese middle-aged and older adults.

Effects of household solid fuel use on sarcopenia in middle-aged and older adults: evidence from a nationwide cohort study.

Household solid fuel use is common in global households and has been linked to changes in handgrip strength and muscle mass. However, whether household solid fuel use results in sarcopenia over time is not well elaborated. This study employed data from the 2011-2015 China Health and Retirement Longitudinal Study (CHARLS) that recruited 4,932 participants ≥45 years. The Cox proportional hazards regression model was conducted to estimate the impact of household solid fuel use for cooking and heating on sarcopenia development. The analysis was further stratified based on geographic position. Mediation analysis was employed to estimate the potential mediating effects of cognitive function and depressive symptoms associated with household solid fuel use and sarcopenia. Over the 4-year follow-up, 476 cases of sarcopenia were reported (9.65%), with 254 in males (10.82%) and 222 in females (8.59%). Cooking and heating with solid fuels increased the risk of sarcopenia (Cooking: HR 1.401, 95% CI 1.138-1.724; Heating: HR 1.278, 95% CI 1.040-1.571). Crop residue/wood burning correlated with higher sarcopenia risk (Cooking: 1.420, 95% CI 1.147-1.758; Heating: 1.318, 95% CI 1.062-1.635). Switching to clean cooking fuels significantly reduced sarcopenia risk (HR 0.766, 95% CI 0.599-0.979). Heating with solid fuels was associated with higher sarcopenia risk only in southern China (HR 1.375, 95% CI 1.102-1.715). Additionally, cognitive function and depressive symptoms partially mediated the link between household solid fuel use and sarcopenia. Household use of solid fuels is associated with an increased risk of sarcopenia. Restricting the use of solid fuels and focusing on cognitive function and depressive symptoms in solid fuel users can help decrease sarcopenia development.

APPRAISAL OF ACCESS TO CLEAN FUELS BY FOOD VENDORS IN ILARO, YEWA SOUTH LOCAL GOVERNMENT AREA, OGUN STATE, NIGERIA

The extensive use of solid fuels in food preparation such as firewood and charcoal presents problems for the environment, human health, and the economy. In Nigeria, more than 175 million people rely on traditional biomass for daily cooking. While significant research has been done on access to clean cooking fuels among households, particularly households in rural areas, there is a gap in the study of access to clean fuels among food vendors in developing countries, including Nigeria. This study explores factors influencing access to clean cooking fuel among food vendors in Nigeria. The study adopts a cross-sectional survey design, a pretested questionnaire was administered to all the registered food vendors in the study area. The results show that a significant number of the food vendors in the study area use solid fuels such as firewood and coal. Probit regression result indicates that education and income are significant factors that increase predicted probability of the use of clean fuel among food vendors. Empirical findings also show that financial constraints, availability and distribution of clean fuel, technical issues, and lack of information on the importance of clean fuel usage are some of the attention-seeking challenges inhibiting the adoption of clean cooking fuels among food vendors. Thus, the study suggests the need for integrated strategies that aim at increasing awareness of the benefits of adopting clean cooking fuels among food vendors, improving the affordability of clean cooking fuels, and providing technical assistance for transitioning into clean cooking fuels.

Dwelling characteristics and mental well-being in older adults: A systematic review

The increasing prevalence of mental health challenges in older adults underscores the need for a comprehensive understanding of the interplay between dwelling characteristics and mental health outcomes. This systematic review aims to investigate house characteristics associated with mental well-being in older adults. The review meticulously explores existing literature from databases such as PubMed, Scopus, Web of Science, and the Google Scholar search engine. The Newcastle-Ottawa Scale (NOS) was utilized to assess the quality of the included articles. Out of an initial 1182 references, 21 pertinent articles published between 2002 and 2023 were included in the study. While the geographical scope was global, a notable concentration of studies was observed in China. The synthesis of studies reveals that specific attributes of dwelling characteristics, such as high-rise and multi-floor houses, larger house size, high house quality, bathing facilities, and the use of clean fuels for heating and cooking, positively impact mental health outcomes in older adults. However, inconsistent results were found regarding the impact of construction materials on mental health outcomes. Further research is warranted to deepen our understanding of the intricate relationship between construction materials and mental health outcomes. These findings underscore the importance of considering specific dwelling characteristics in designing interventions to enhance the mental well-being of older adults, necessitating targeted strategies for creating age-friendly living environments.

Climate shocks, adaptive mechanisms and household energy transition in Uganda

Nearly 41% of the global populace depends on unclean fuels for cooking. As a result, about 4 million premature deaths connected to household air pollution are registered annually. Worryingly, over 2.1 billion people are estimated to continue using unclean fuels by 2030 if no strong policy actions are taken to alter the status quo. Climate parameters including; temperature, solar radiation, wind, and moisture have been widely touted as having an impact on multidimensional energy poverty, their effect on household energy consumption and subsequent transition to cleaner fuels is seldom investigated in Uganda. The purpose of this study is to investigate the effect of climate shocks, and adaptation mechanisms on household energy transition in Uganda. The study adopted a panel data methodology employing an ordered logit model with random effects to estimate the effect of climate shocks and adaptation mechanisms on household fuel transition from high to low-pollutant cooking fuels in Uganda. The findings revealed that climate shocks, adaptation mechanisms significantly affect household energy transition in Uganda. The study recommended that policies aimed at enhancing detection and report of early warning signs should be emphasized. Furthermore, investing in an insurance scheme especially for people living in climate shock prone areas can help households to cope up with shocks are eventually transition to clean cooking fuels.

Understanding the socioeconomic determinants of cooking fuel expenditure in Uttar Pradesh, India

Poor people in a developing country like India face energy poverty and are deprived of clean cooking fuel. Clean cooking fuels are costlier and require more willingness to pay (WTP) from the consumer. Therefore, this is a descriptive study aims to analyze factors associated with differences in cooking fuel expenses at the household level in Uttar Pradesh, India. For this purpose, panel data from the Consumer Pyramids Household Survey of CMIE from 2014 to 2019 has been considered. The study uses fixed-effect panel data model to control individual-specific effects. Cooking fuel expenses show positive elasticity concerning per capita income. However, this elasticity is lower for the higher-income group than the bottom-income group. Less educational attainments of households are associated with lower spending on cooking fuel. Moreover, households with better access to electricity are willing to spend more on cooking fuel expenditure. Hence, improved access to electricity nudges households towards more WTP for cooking fuel. It is further confirmed by finding a positive association between electricity-using household appliances and cooking fuel expenses. Therefore, improved access to electricity may increase the WTP for cooking fuel and adopt clean cooking fuel in different ways. This suggests positive spillover effects of modern energy services on clean cooking fuel.

Empirical analysis of solid biomass fuel and ill-health

The Sustainable Development Goal (SDG) seven highlights the need to ensure access to affordable, reliable, sustainable, and modern energy for all. Improving access to reliable and affordable modern energy for cooking have far-reaching benefits on human health and the environment. In most developing countries, the use of solid biomass fuel (SBF) for cooking is widespread. Using a nationally representative household-level data from Ghana and the biprobit model, this paper examines the relationship between SBF and ill-health. The first stage results show that the adoption of SBF is significantly influenced by socio-economic factors, rental and dwelling status, food hardship, information about SBF, and geographical controls. The adoption of SBF for cooking increases the probability of a household reporting ill-health and frequently reporting ill-health by 25% each, respectively. The differential analysis indicates that charcoal has a moderate effect on ill-health relative to using wood as fuel for cooking. The findings of the study imply that households are more likely to improve their health with increasing affordability and use of clean cooking fuels. Government programs on the promotion of clean energy fuels must be intensified and make more accessible and affordable to households.

Energy-Efficient Electric Cooking and Sustainable Energy Transitions

Transitioning to clean cooking fuels is not only part of achieving SDG7 but also makes a significant contribution to mitigating climate change by reducing carbon emissions. Research projects and pilots across a number of countries in Africa and South Asia have been exploring the suitability and energy performance of different cooking appliances and fuels. The paper presents the first statistical analysis across these multiple datasets to determine the range of energy required to cook dishes using different technologies and fuels. The paper draws out distinctions between African and Asian dishes, notably the impact of energy-intensive dishes prepared mostly in Africa. The paper demonstrates that the standard efficiency-based approaches to comparing the performance of stoves are not appropriate to modern electric cooking devices, so a novel alternative approach based on specific energy consumption and termed energy ratios is developed. Charcoal stoves are shown to use 15 times as much energy as electric pressure cookers (EPCs) to cook African dishes, and a detailed review of how the EPC works explains why this should be. Energy ratios provide a basis for estimating carbon emission reductions associated with transitioning to modern cooking fuels and also for estimating household cooking costs. Fuel and electricity prices from studies show that the cost of cooking with an EPC can be only 20% of the cost of cooking with charcoal, which highlights the potential for modern, energy-efficient electric cooking devices to defy the conventional wisdom of the energy ladder.

Assessment of Energy Poverty and Alleviation Strategies in the Global South

The incidence of energy poverty in the Global South is identified by the lack of basic access to modern fuels and energy carriers. Impoverished people have traditional biomass and human power as their only sources of energy. This situation of deprivation of basic resources, in which (according to estimates of international agencies) almost one third of the world’s population lives, masks other relevant characteristics of energy poverty. Current assessments of energy poverty in impoverished areas and the mitigation strategies being implemented are derived from the development agenda and, with variations in detail and scope, highlight electricity connections and access to clean cooking fuels as guarantors of progress. However, a comprehensive understanding of energy poverty requires focusing beyond basic access, building on the interactions between the supply of energy sources and carriers, the provision of energy services, and their impact on decent living conditions. To deal with the effects of these interactions on the energy poor, several studies have attempted in the last decade to construct an assessment framework centred on energy services. This work discusses the relevant dimensions in the framework (supply, services, and impact on wellbeing), reviews the multidisciplinary work available in each aspect, presents a range of proposed taxonomies, and discusses the different issues. A detailed framework is proposed for the integrated assessment of the supply of energy carriers and energy equipment, the provision of relevant energy services, and the improvements obtained in living conditions.

Transition of cooking fuels and obesity risk in Chinese adults

BackgroundSince 1990 s, China has witnessed a widespread transition to clean cooking fuels, presenting an opportunity to investigate whether household fuel transition could mitigate obesity risk and reconcile inconsistencies in the literature regarding the association between cooking fuels and obesity. MethodsThe China Health and Nutrition Survey (CHNS) is a prospective cohort study covering 12 provinces of China (1989–2015). Participants were classified into persistent cleaner fuel users, fuel transitioners, and persistent polluting fuel users according to self-reported primary cooking fuels. Obesity and central obesity were defined as BMI ≥ 28.0 kg/m2 and waist circumference ≥ 90 cm in men and ≥ 85 cm in women according to Chinese criteria. FindingsAmong 13,032 participants, 3657 (28.06 %) were persistent cleaner fuel users; 5264 (40.39 %) transitioned from using polluting fuels to cleaner fuels after the baseline survey; and 4111 (31.55 %) were persistent polluting fuel users. During the period of follow-up of 9.0 ± 6.8 years, 1248 (9.58 %) participants were classified into the obesity category, and 4703 (36.09 %) into the central obesity category. Persistent polluting fuel users had a significantly higher risk of developing obesity (hazard ratio [HR]: 1.45, 95 %CI: 1.22–1.72) and central obesity (HR: 1.32, 95 %CI: 1.21–1.44), compared to persistent cleaner fuel users. Persistent polluting fuel use was positively associated with developing obesity in women (HR: 1.64, 95 %CI: 1.30–2.06), but not in men. Subgroup analyses showed higher HR of persistent polluting fuel use among individuals aged 18–44 years (HR: 2.04, 95 %CI: 1.62–2.56). In contrast, the transitioners did not exhibit a significantly different risk of developing obesity (HR: 0.94, 95 %CI: 0.80–1.10) compared to persistent cleaner fuel users, which was consistent across different sex, age and urbanicity. Similar trends were observed for developing central obesity. InterpretationPersistent polluting fuel use increased obesity risk while the obesity risk of the transition to cleaner fuels was similar to persistent use of cleaner fuels. The finding underscores the significance of advocating for the adoption of cleaner fuels as a strategy to mitigate the disease burden associated with obesity.

Household Environments and Cognitive Decline Among Middle-Aged and Older Adults in China: Exploring Gender, Age, and Residential Variations

This study examined the relationship between household environments and trajectories of cognitive function among middle-aged and older adults in China and its urban/rural, gender, and age variations. We estimated multi-level linear growth curve models using a representative sample of 16,111 respondents aged 45 years and over from the China Health and Retirement Longitudinal Study (2011–2018). Older people who lived with a spouse, but not with children, and those with higher living expenditures, better housing quality, and indoor clean fuels for cooking had a slower cognitive decline. Living arrangement more strongly predicted men's cognitive decline, while living expenditure, solid fuel use, and housing quality significantly predicted only women's cognitive decline. Only for older adults and rural residents, those living alone had significantly faster cognitive decline than those living with a spouse only. These findings underscore the importance of improving the living conditions of older adults to help alleviate their cognitive decline.

Effects of indoor air pollution from household solid fuel use on the risk of gastrointestinal and liver diseases in middle aged and elderly adults

Solid fuels are widely used in China and increase the concentrations of indoor air pollutants. Nevertheless, there is limited longitudinal evidence linking solid fuel use and Gastrointestinal (GI) and liver diseases. This study aimed to prospectively investigate the association between household solid fuel use and the risk of GI and liver diseases in middle aged and elderly adults. This work was based on the China Health and Retirement Longitudinal Study (CHARLS). Longitudinal data incorporate with cross-sectional data were analyzed. Compared with individuals using clean fuel for cooking, solid fuel users were observed to have higher risk of GI diseases (OR in 2011, 2013, 2015, 2018 wave separately: 1.37, 95 % CI: 1.24–1.50, P < 0.001; 1.24, 95 % CI: 1.11–1.39, P < 0.001; 1.18, 95 % CI: 1.06–1.33, P < 0.001; 1.23, 95 % CI: 1.04–1.45, P < 0.05). The associations between solid fuel use and liver diseases were not significant in most of the groups. Participants transforming from solid to clean cooking fuels had lower risk of GI and liver diseases than persistent solid fuel users. Moreover, biomass cooking fuel users were at a significant higher risk of both liver and GI diseases compared with clean fuel users. Overall, household solid fuel use, especially for cooking, was related to higher risk of GI and liver diseases, while switching from solid to clean fuels could reduce this risk. Using biomass for cooking was identified to be more associated with the increasing risk of GI and liver diseases than cooking with coal.

Energy access and female labor force participation in developing countries

Access to reliable modern energy services and female economic empowerment are vital for sustainable development of developing countries. While micro-level evidence suggests that energy access can alleviate women's household burdens and enhance their labor market participation, there is little macro-level evidence on this relationship and limited insights on how institutional environments influence it. This study fills this gap using a national-level dataset covering 78 developing countries from 2000 to 2020 and analyzing how access to electricity and clean cooking fuels affects women's labor supply and demand, respectively. Results show that clean energy access increases female labor force participation, particularly in rural areas and small island developing countries. Electricity access reduces female unemployment, especially in urban areas and African countries. Moreover, the importance of country risk and governance capability in shaping this relationship is highlighted. These findings provide valuable insights for enacting synergy policies targeting sustainable development goals.

Gendered health effects of cooking fuel technologies in southern Ghana

The introduction of clean cooking technologies in many developing countries ensures environmental quality and improved well-being through reduction in indoor air pollution. This study examines the adoption of cooking fuel technologies and its effect on health outcomes using panel data from two districts in the Greater Accra region of Ghana. The inverse probability weighting regression adjustment (IPWRA) approach was used to examine the effect of cooking fuel technologies on health outcomes. The empirical results show that factors such as tenancy, kitchen design, assets, gender, education, access to internet and tarred roads influence the adoption of cooking fuel technologies, including clean cooking fuels. The study finds that clean cooking fuels decrease female illness incidence but not male illness incidence, with large improvement for adults. The findings suggest that policies and programs aimed at promoting clean cooking fuel technologies can significantly improve well-being of females in developing countries.

Pain in Solid and Clean Fuel Using Households

Household air pollution from solid cooking fuel use influences multiple health outcomes, but its association with body pain remains poorly understood. This was a longitudinal study of 8880 adults who participated in the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018. Household cooking fuels were extracted from the baseline household questionnaire. Transitions in cooking fuels from 2011 to 2018 were also identified. Body pain status was reported in the three waves of surveys conducted in 2011, 2015, and 2018. The associations between cooking fuel type, fuel transition, and pain site number were examined using generalized estimating equations. Among the 8880 participants, 41.4% (n=3680) primarily used clean fuels for cooking, and 58.6% (n=5200) used solid ones at baseline. Cooking with solid fuels was associated with more pain sites (incidence rate ratio (IRR): 1.14; 95% confidence interval (CI): 1.08 to 1.21), but a slower rate of pain sites increases from 2011 to 2018 (IRR=0.78; 95% CI: 0.71 to 0.86, for 2018×solid fuels). Compared with those who persistently used clean fuels for cooking, the number of pain sites increased by 10% in participants who transiting from using solid to clean fuels (IRR=1.10; 95% CI: 1.04 to 1.18), by 21% in those transiting from cooking with clean to solid fuels (IRR=1.21: 95% CI: 1.08 to 1.35) and by 25% among those persistent using solid fuels for cooking (IRR=1.25; 95% CI: 1.18 to 1.34). Our findings provided new evidence linking using solid fuels for cooking with more pain sites, but a slower rate of pain sites increases. Public health efforts should focus on fuel transition and take measures to help clean fuels spread.

Association between cooking fuel exposure and respiratory health: Longitudinal evidence from the China Health and Retirement Longitudinal Study (CHARLS)

The epidemiological evidences for the association between cooking fuel exposure and respiratory health were inconsistent, and repeated-measures prospective evaluation of cooking fuel exposure was still lacking. We assessed the longitudinal association of chronic lung disease (CLD) and lung function with cooking fuel types among Chinese adults aged ≥ 40 years. In this prospective, nationwide representative cohort of the China Health and Retirement Longitudinal Study from 2011 to 2018, 9004 participants from 28 provinces in China were included. CLD was identified based on self-reported physician diagnosis in 2018. Lung function was assessed by peak expiratory flow (PEF) in 2011, 2013 and 2015. Multivariable logistic and linear mixed-effects repeated-measures models were conducted to measure the associations of CLD and PEF with cooking fuel types. Three-level mixed-effects model was performed as sensitivity analysis. Among the participants, 3508 and 3548 participants used persistent solid and clean cooking fuels throughout the survey, and 1948 participants who used solid cooking fuels at baseline switched to clean cooking fuels. Use of persistent clean cooking fuels (adjusted odds ratio [aOR] = 0.73, 95 % confidence interval [CI]: 0.61, 0.88) and switch of solid fuels to clean fuels (aOR = 0.81, 95 % CI: 0.67, 0.98) were associated with lower risk of CLD. The use of clean cooking fuels throughout the survey and switch of solid fuels to clean fuels in 2013 were also significantly associated with higher PEF level. Similar results were observed in stratified analyses and different statistical models. The evidence from CHARLS cohort suggested that reducing solid cooking fuel exposure was associated with lower risk of CLD and better lung function. Given the recent evidence, improving household air quality will reduce the burden of chronic lung diseases.

Clean Cooking Fuels Use and Its Determinants in Assam

The research highlighted the access to clean fuels in the Kokrajhar district of Assam. The expenditures and factors determining the use of clean cooking fuels were analysed. The sample consisted of 100 households selected randomly, considering both rural and urban. It was found that 45 and 55 per cent of households used clean cooking and clean and dirty fuels. The determinants of clean cooking fuels were families' monthly income, fuel expenditure, LPG connection, and kitchen, which were statistically significant. It was the same for urban areas, but only monthly expenditure on cooking fuels was highly significant in rural areas. Thus, the stakeholders should focus more on subsidies and frequently organize awareness programs, especially in rural areas, to encourage the practice of clean fuels.

Consumption of clean and dirty cooking fuels in ghanaian households: The role of financial inclusion

Home cooking is considered an important activity which promotes healthier lives, sustenance, and binds families and people together. Despite the benefits of home cooking, it is the leading source of household air pollution and its associated health risks particularly for developing countries including Ghana. The role of financial inclusion in facilitating the achievement of the Sustainable Development Goals (SDGs) of the United Nations is explored in this study for clean cooking technologies (i.e., SDG 7). The proposed study is based on three datasets from the Ghana Statistical Service (GSS), comprising of Ghana Living Standard Survey (GLSS) round 6, round 7 and the pooled form. Using distance to the nearest financial institution as instrument, the study employed probit two-stage least squares to investigate the heterogenous impacts of financial inclusion on household cooking fuels in Ghana. The findings show that financial inclusion increases the consumption of clean cooking fuel but reduces dirty fuels such as firewood, charcoal, kerosene etc. Female-headed households were found to be more impacted by financial inclusion over time than their male counterparts. The results also showed that financially included rural households reduced their consumption of dirty cooking fuels than their urban counterparts. These findings have important policy implications.

Will environmental concern contribute to the transition of household cleaner cooking?

Access to clean cooking is a vital sustainable development goal, yet achieving it poses challenges within the current trend. We should now investigate whether the increasing environmental concern would drive a shift towards cleaner cooking or potentially lead to the abandonment of pro-environmental behaviors. Based on China's national micro survey data from 2012 to 2018, the results of multiple econometric models are: (1) Residents' environmental concern about environmental issues positively contributes to households use of non-solid clean cooking fuels. (2) Rising income levels and urbanization promote a smoother transition towards cleaner cooking. (3) Higher education and Internet access can reinforce the role of environmental concern. (4) The transition to cleaner cooking fuels has a net reduction in household expenditure, as it slightly increases fuel costs but significantly reduces health expenditures. The importance of environmental concern in household energy decision-making is highlighted, and suggestions are provided to promote the cleaner transition of household cooking energy.
