Household energy choice for domestic cooking: distribution and factors influencing cooking fuel preference in Ouagadougou.

Many studies have highlighted the link between indoor air pollution from the burning of solid fuels for cooking and heating and the occurrence of various health problems particularly in women and children under 5 years. In developing countries, solid fuels remain the main sources of energy. The purpose of this study aims to describe the distribution of household cooking fuel types and to analyze the factors influencing household cooking energy choice in Ouagadougou. A cross-sectional survey was conducted in 2017 in 3 neighborhoods of Ouagadougou. A total of 1734 household were randomly selected. We performed a multivariable logistic regression and a multinomial logistic regression to measure the relationship between selected determinants and households' primary cooking fuel. 59.53% of the households of Ouagadougou reported using solid fuels as the main cooking fuel. Wood is the most common primary cooking fuel used (43.93%), followed by LPG (40.41%) and then charcoal (15.60%). About 84% combine at least 2 types of energy for cooking. Cooking fuel choice is strongly influenced by the socioeconomic status, the family size, and also by the woman's educational attainment, her age and the main cooking fuel used in her parents' house. Actions aimed at reducing the impact of solid fuel use in the environment or health must consider these factors.

Primary Cooking Fuel Choice and Respiratory Health Outcomes among Women in Charge of Household Cooking in Ouagadougou, Burkina Faso: Cross-Sectional Study.

Background: Approximately 3 billion people, worldwide, rely primarily on biomass for cooking. This study aimed to investigate the association between respiratory symptoms among women in charge of household cooking and the type of fuel used for cooking. Methods: A community-based cross-sectional survey was conducted. A total of 1705 women that were randomly selected, completed the survey. We also performed a bivariate and a multivariate analysis to verify the possible associations between respiratory symptoms in women in charge of household cooking and the type of cooking fuel used. Results: Dry cough, breathing difficulties, and throat irritation frequencies were statistically high in biomass fuel users when compared to liquefied petroleum gas (LPG) users. It was also the case for some chronic respiratory symptoms, such as sputum production, shortness of breath, wheezing, wheezing with dyspnea, wheezing without a cold, waking up with shortness of breath, waking up with coughing attacks, and waking up with breathing difficulty. After adjustment for the respondents' and households' characteristics; dry cough, breathing difficulties, sneezing, nose tingling, throat irritation, chronic sputum production, wheezing, wheezing with dyspnea, wheezing without a cold, waking up with shortness of breath, waking up with coughing attacks, and waking up with breathing difficulty were symptoms that remained associated to biomass fuel compared to LPG. Women who used charcoal reported the highest proportion of all the chronic respiratory symptoms compared to the firewood users. However, this difference was not statistically significant except for the wheezing, waking up with coughing attacks, and waking up with breath difficulty, after adjustment. Conclusion: Exposure to biomass smoke is responsible for respiratory health problems in women. Charcoal, which is often considered as a clean fuel compared to other biomass fuels and often recommended as an alternative to firewood, also presents health risks, including increased respiratory morbidity in women. Effective and efficient energy policies are needed to accelerate the transition to clean and sustainable energies.

Prevalence of wasting and associated factors among 6 to 23 months old children in the Sahel Region of Burkina Faso.

INTRODUCTION: Despite the efforts of nutrition stakeholders in Burkina Faso to improve infant and young child feeding (IYCF) practices, the country is still struggling to stem undernutrition. Wasting, or acute malnutrition, is the form of malnutrition that has the most harmful short-term consequences for children. The objective of our study was to estimate the prevalence of wasting in children aged 6-23 months in the Sahel region of Burkina Faso and to identify its associated factors. METHODS: We conducted a secondary analysis of data from the 2015 National Nutrition Survey. The factors associated with wasting in the studied population were identified using a logistic regression. RESULTS: A total of 956 children participated in the study. The prevalence of wasting was 25% (95% CI [22.28, 27.87]) in the Sahel region. Only 24.37% of children received a minimum meal frequency and 13.38% received a minimum dietary diversification the day before the survey. In the multivariate analysis, being male (aOR = 1.99; 95% CI [1.46, 2.72]), breastfeeding the day before the survey (aOR = 2.43; 95% CI [1.13, 5.22]), and having a history of illness (aOR = 2.32; 95% CI [1.67, 3.21]) significantly increased the risk of acute malnutrition. CONCLUSION: In 2015, the prevalence of wasting among children was high in the Sahel region and good IYCF practices were still inadequate. There is an urgent need to implement good IYCF practices and strengthen interventions to improve infant health in this region.

[Indoor air pollution and acute respiratory infection prevalence in infants in Ouagadougou.] / Pollution de l'air intérieur et prévalence des infections respiratoires aiguës chez les enfants à Ouagadougou.

In Burkina Faso, women and their young children are the most exposed to the effects of indoor air pollution. This study investigated the risk factors associated with air pollution during meal cooking in the occurrence of Acute Respiratory Infections (ARI) in children under 5 years of age. This is a cross-sectional study that took place in two sectors of the city of Ouagadougou (sectors 15 and 17) in Burkina Faso. The study involved 608 households. The data was collected using an interview guide and an observation grid. The data was entered with Epi data 3.1 software and analyzed with Stata / SE 12.0. The associations between the variables were expressed in Odds Ratio (OR) and their confidence intervals were estimated at 95%. The prevalence of ARI was 3.5% in children under 5 years of age. In bivariate analysis, with low-standing habitats, the use of traditional and / or improved stoves, appeared to be a risk factor for ARI. In multivariate analysis, only the use of the combination ? improved stoves + wood ? was found to be significantly associated with ARI in the last 2 weeks before the study (OR = 14.703, 95% CI: 1.156 -186.887). This requires strengthening the promotion of the use of gas and conducting studies on the effectiveness of improved stoves in reducing exposure to pollutants.

Chronic obstructive pulmonary disease associated with biomass fuel use in women: a systematic review and meta-analysis.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is a major and growing cause of morbidity and mortality worldwide. The global prevalence of COPD is growing faster in women than in men. Women are often exposed to indoor pollutants produced by biomass fuels burning during household activities. METHODS: We conducted a meta-analysis to establish the association between COPD and exposure to biomass smoke in women.Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we searched MEDLINE and Scopus databases in 31December 2016, with the terms: "wood", "charcoal", "biomass", "solid fuels", "organic fuel", "biofuel", "female", "women", "COPD", "chronic bronchitis", "emphysema", "chronic obstructive pulmonary disease". Studies were eligible if they were case-control or cross-sectional studies involving exposure to indoor biomass smoke, conducted at any time and in any geographic location. Fixed-effects or random-effects meta-analysis was used to generate pooled OR. RESULTS: 24 studies were included: 5 case-control studies and 19 cross-sectional studies. Biomass-exposed individuals were 1.38 times more likely to be diagnosed with COPD than non-exposed (OR 1.38, 95% CI 1.28 to 1.57).Spirometry-diagnosed COPD studies failed to show a significant association (OR 1.20, 95% CI 0.99 to 1.40). Nevertheless, the summary estimate of OR for chronic bronchitis (CB) was significant (OR 2.11, 95% CI 1.70 to 2.52). The pooled OR for cross-sectional studies and case-control studies were respectively 1.82 (95% CI 1.54 to 2.10) and 1.05 (95% CI 0.81 to 1.30). Significant association was found between COPD and biomass smoke exposure for women living as well in rural as in urban areas. CONCLUSIONS: This study showed that biomass smoke exposure is associated with COPD in rural and urban women.In many developing countries, modern fuels are more and more used alongside traditional ones, mainly in urban area. Data are needed to further explore the benefit of the use of mixed fuels for cooking on respiratory health, particularly on COPD reduction.

Knowledge and perceptions of health and environmental risks related to artisanal gold mining by the artisanal miners in Burkina Faso: a cross-sectional survey.

INTRODUCTION: Artisanal gold mining is an activity ensuring the survival of about 700,000 families in Burkina Faso with a considerable contribution to the national economy. Techniques and chemicals used in the operation, have adverse impacts on health and the environment. Our study aims to evaluate the perceptions and knowledge of these different impacts among artisanal gold miners. METHODS: A cross-sectional survey was conducted in artisanal gold mines Bouda and Nagsene in the region of the North of Burkina Faso. Two hundred miners over 18 years of age were interviewed. RESULTS: All the participants have recognized that gold mining has health impacts and 88.5% felt these impacts as important with a significantly higher proportion among those with more than 3 years' seniority (p = 0.001). The environmental impacts were perceived as important by 64.5% of miners, with a significant difference according to the position (p = 0.004). Sixty percent (60%) of respondents could identify at least 3 of the 5 health impacts of gold mining listed and 49.5% acknowledged at least 3 impacts on the environment. The diggers had significantly more knowledge about the symptoms (p < 0.001). CONCLUSION: Study highlights the lack of knowledge of the Stampeders on the health and environmental impacts of artisanal gold mining. Findings might be used to develop more effective awareness campaigns in the future. Communication with diggers must focus on the risk perception because it appears that raising risk perceptions from low to high would have a major effect on behavior.
