“…52 The finding that active tobacco smoking is associated with significantly increased risk of asthma is also consistent with previous research. [53][54][55][56] However, active tobacco smoking is not a major confounder in this study because only a small proportion of women in India smoke tobacco (only 2.3% in the NFHS-2 sample). 4 A positive significant effect of biomass fuel use on asthma is also consistent with previous research linking cooking smoke to asthma.…”

OBJECTIVE: Both obesity and asthma are on the rise worldwide. This study examined the association between obesity and asthma prevalence in adult women in India. METHODS: The analysis used information on 82 464 nonpregnant, ever-married women aged 15À49 y, included in India's 1998À99 National Family Health Survey. The effects of measured Body Mass Index (BMI) on reported asthma were estimated using logistic regression, after adjusting for tobacco smoking (active and passive), cooking smoke, age, education, work status, media habits, food habits, house type, separate kitchen, indoor crowding, religion, caste/tribe, household living standard, urban/rural residence, and geographic region. RESULTS: Obese women (BMIZ30.0 kg/m 2 ) were about twice as likely as those with a normal BMI (18.5À25.0 kg/m 2 ) to report suffering from asthma (OR ¼ 1.92; 95% CI: 1.40À2.65). The association between obesity and asthma remained strong and statistically significant even when the effects of other selected risk factors and potential confounders were controlled (OR ¼ 1.85; 95% CI: 1.30À2.63). Overweight women (25.0rBMIo30.0 kg/m 2 ) also reported significantly higher adjusted asthma prevalence than those with a normal BMI (OR ¼ 1.32; 95% CI: 1.07À1.63). Results hold in separate analysis for younger (15À29 y) and older (30À49 y) women. CONCLUSION: The study finds a strong positive association between obesity and asthma among adult Indian women. To validate this relationship and to establish causality, prospective epidemiological studies, with better measures of overweight conditions and clinical measures of asthma, are needed in developing-country settings.

“…A cohort study of schoolchildren in Japan 24 found a significant association between the prevalence of respiratory symptoms and indoor nitrogen dioxide in girls but not in boys. A Swedish study, 25 however, reported an essentially similar risk of asthma related to visible mold growth among men (OR: 2.7) and women (OR: 2.0). Pershagen et al 26 also suggested that environmental exposure did not differ between boys and girls.…”

Indoor and Outdoor Environmental Exposures, Parental Atopy, and Physician-Diagnosed Asthma in Taiwanese Schoolchildren

ABSTRACT. Objective. Parental atopy and environmental exposures are recognized risk factors for childhood asthma. However, the relative contributions of specific risk factors and the overall contributions of indoor and outdoor exposures remain unexplored. This study was undertaken to identify risk factors, estimate the population attributable risk of each exposure, and compare the data for boys versus girls for physician-diagnosed asthma in Taiwanese schoolchildren.Methods. During a February to June 2001 cross-sectional national survey, 35 036 6-to 15-year-old schoolchildren were chosen from 22 elementary and 22 middle schools located within 1-km catchment areas of 22 airmonitoring stations in Taiwan. The main outcome measure was physician-diagnosed asthma, as reported by the parents. We investigated hereditary and indoor and outdoor environmental factors for childhood asthma by questionnaire. The adjusted prevalences of questionnaire-determined outdoor indicators were also compared with air-monitoring data.Results. Outdoor air pollutants were associated with parent-reported perceived ambient air pollution. Physician-diagnosed asthma was reported for 8.1% of the boys (1330 of 16 441) and 5.6% of the girls (894 of 16 056). The risk of physician-diagnosed asthma was significantly associated with parental atopy and perceived ambient air pollution in both sexes. A sthma is the single most common chronic childhood disease in developed nations, 1,2 and its prevalence and severity have been reported as increasing in many countries. [3][4][5][6] The changing pattern of the disease has not been fully explained, in part because of an incomplete understanding of its pathogenesis. The change has been too rapid to be accounted for by changes in gene frequencies. It is also unlikely that the increase can be totally accounted for by changes in either clinical diagnostic patterns or increased recognition of asthma symptoms by the general population. 7 This does, however, suggest a role for environmental exposures in the cause of this evolving epidemic. 8 Many factors have been proved to be associated with the prevalence and/or attacks of asthma, including personal factors (smoking habits, genetics, age, sex, nutritional status, number of siblings, coexisting lung disease, lifestyle, allergy status, family history, and occupation) and environmental stimuli (house dust, animal danders, molds, cockroach infestation, occupational exposure, environmental tobacco smoke, indoor/outdoor air pollution, cooking fumes, aeroallergens, and climate). 9 -29 Both genetic and environmental factors are believed to contribute to the relationship. However, epidemiologic evidence concerning different effects in boys and girls in relationships between environmental exposures and childhood asthma was insufficient and warranted additional investigations.The first aim of this study was to investigate the relationship between physician-diagnosed asthma and selected risk factors in a population-based sample of 6-to 15-year-old elementary-and middleschool...

“…Anecdotal association of asthma with cooking smoke is common, but few epidemiologic studies seem to have been done (25). Of the limited research that does exist on this issue, some studies have found a positive association between biomass fuel exposure and asthma (10,(54)(55)(56)(57)(58), whereas others found no significant relationship (48,59,(60)(61) or found a protective effect (62,63).…”

Objectives-Increasing prevalence of asthma in developing countries has been a significant challenge for public health in recent decades. A number of studies have suggested that ambient air pollution can trigger asthma attacks. Biomass and solid fuels are a major source of indoor air pollution, but in developing countries the health effects of indoor air pollution are poorly understood. In this study we examined the effect of cooking smoke produced by biomass and solid fuel combustion on the reported prevalence of asthma among adult men and women in India.Methods-The analysis is based on 99,574 women and 56,742 men aged between 20 and 49 years included in India's third National Family Health Survey conducted in [2005][2006]. Effects of exposure to cooking smoke, determined by the type of fuel used for cooking such as biomass and solid fuels versus cleaner fuels, on the reported prevalence of asthma were estimated using multivariate logistic regression. Since the effects of cooking smoke are likely to be confounded with effects of tobacco smoking, age, and other such factors, the analysis was carried out after statistically controlling for such factors.Results-The results indicate that adult women living in households using biomass and solid fuels have a significantly higher risk of asthma than those living in households using cleaner fuels (OR: 1.26; 95%CI: 1.06-1.49; p = .010), even after controlling for the effects of a number of potentially confounding factors. Interestingly, this effect was not found among men (OR: 0.98; 95%CI: 0.77-1.24; p = .846). However, tobacco smoking was associated with higher asthma prevalence among both women (OR: 1.72; 95%CI: 1.34-2.21; p < .0001) and men (OR: 1.35; 95%CI: 1.49-2.25; p < .0001). Combined effects of biomass and solid fuel use and tobacco smoke on the risk of asthma were greater and more significant in women (OR: 2.16; 95%CI: 1.58-2.94; p < .0001) than they were in men (OR: 1.34; 95%CI: 1.04-1.72; p = .024). Conclusions-The Europe PMC Funders Group
