Prevalence trends of wood use as the main cooking fuel in Mexico, 1990-2013

Abstract

Objective. To determine prevalence trends of using Wood as the Main Cooking Fuel (WMCF) ResumenObjetivo. Determinar las tendencias temporales de prevalencia del uso de leña utilizada para cocinar (ULPC) y características del hogar que lo predicen. Material y métodos. Los estimados se obtuvieron de los censos 1990, 2000 y 2010 y de la encuesta nacional de 2012-2013. Resultados. En el periodo 2012-2013, 9.5% de los 66 321 hogares y 10.9% de sus 252 011 residentes usaron LPC. La prevalencia fue mayor en áreas rurales (40.5%) que las urbanas (1.5%), p<0.0001. De 1990 a 2013 el ULPC disminuyó 53% en todo el país y 28.6% en áreas rurales. Contrariamente, el uso de gas incrementó 17.5 y 52.7% respectivamente. Los predictores del ULPC fueron el vivir en áreas rurales o suburbanas, y aquellos asociados al nivel socioeconómico bajo. Conclusión. El ULPC ha disminuido pero a ritmo lento en las áreas rurales de México. Mejorar las características del hogar y nivel socioeconómico pudiera disminuir el ULPC a mayor ritmo.

Lung cancer mortality and municipal marginalization in Mexico, 1998-2016

“…However, so far there are lack of studies that evaluate the national prevalence at individual level of this exposure and its evolution over time, in these populations. 4,5 Based on the above, it is important to point out that although the control and reduction of preventable risk factors are important to reduce the mortality burden attributable to LC, these are not the only means to reduce incidence and mortality for LC, unless accompanied by measures that ensure access to an opportune diagnosis and treatment, especially of the most vulnerable groups given their unfavorable social determinants. 9,16,17 The main advantage of this study is the national representativeness and the disaggregation of the IM at municipal level which highlights inequalities that can be difficult to identify with the analysis of the level of marginalization by federal entity.…”

“…3 In rural zones, slight changes have been observed in the prevalence of this risk factor; between 2012 and 2013 the prevalence of this factor was 44.5%. 4 Smoking is associated with 71% of LC mortality. SHS can raise the risk of LC to up to 30% for non-smoking individuals who live with a smoker; BSE can be the only related risk factor in up to 27% of the incident cases seen at the National Cancer Institute of Mexico (Instituto Nacional de Cancerología, Incan), particularly among women.…”

“…3,5 Analysis of LC mortality trend is important as changes in incidence and mortality of this tumor can be partly attributed to changes in the prevalence these and other risk factors which in turn have been reported to be unequally distributed in populations according to sex, age, socioeconomic status (SES) and other social and structural determinants such as geographical and economical environments (rural vs. urban). [2][3][4][5] Furthermore, differences by country in LC mortality according to the level of development can be partially explained by the efficacy of health promotion interventions in well-defined targeted populations, by the access to prevention methods to increase timely diagnosis (as effective screening programs) as well as by treatment access. 6,7 For that reason, the study of marginalization and dynamic patterns of LC mortality is relevant.…”

Asthma mortality among Mexican children: Rural and urban comparison and trends, 1999‐2016

“…13 However, this is the first Mexican study that compared mortality rates by zone of residence, gender, and age group and the findings indicate that the decrease in asthma mortality is occurring specifically in Indoor pollution resulting from solid fuel combustion has also been considered a risk factor for asthma in rural zones 26 of wood use for cooking in Mexico (1.5%, 9.8%, and 40.5% for urban, suburban, and rural zones, respectively). 28 The still higher prevalence of wood use as the main cooking fuel in rural vs urban zones may explain in part the results of a higher mortality in rural vs urban zones.…”
