“…In this study, none of the children and mothers demonstrated combined defect. Other studies focusing on populations exposed to cookstove emissions in India have found all three patterns of lung‐function impairments among the participants (Dutta & Ray, ; Mukherjee et al, ; Norboo, Yahya, Bruce, Heady, & Ball, ). One limitation in studies obtaining PFTs in the field is the inability to obtain lung volumes using plethysmography techniques.…”

“…For example, Patel et al (2017) monitored spatio-temporal PM 2.5 in multiple locations of different types of Indian households using similar cookstoves and fuels, and reported that PM 2.5 levels in the living space and bedroom were comparable to that in the kitchen area, even in bigger households than those that participated in this study. which the 95% CI did not include the null value (OR = 1) are presented ( focusing on populations exposed to cookstove emissions in India have found all three patterns of lung-function impairments among the participants (Dutta & Ray, 2014;Mukherjee et al, 2014;Norboo, Yahya, Bruce, Heady, & Ball, 1991).

Half of the world's population still relies on solid fuels to fulfill its energy needs for cooking and space heating, leading to high levels of household air pollution (HAP), adversely affecting human health and the environment. A cross-sectional cohort study was conducted to investigate any associations between: (1) HAP metrics (mass concentration of particulate matter of aerodynamic size less than 2.5 μm (PM ), lung-deposited surface area (LDSA) and carbon monoxide (CO)); (2) a range of household and socio-demographic characteristics; and (3) lung function for women and children exposed daily to biomass cookstove emissions, in rural southern India. HAP measurements were collected inside the kitchen of 96 households, and pulmonary function tests were performed for the women and child in each enrolled household. Detailed questionnaires captured household characteristics, health histories and various socio-demographic parameters. Simple linear and logistic regression analysis was performed to examine possible associations between the HAP metrics, lung function and all household/socio-demographic variables. Obstructive lung defects (forced vital capacity (FVC) ≥ lower limit of normal (LLN) and forced expiratory volume in 1 second (FEV )/FVC < LLN) were found in 8% of mothers and 9% of children, and restrictive defects (FVC < LLN and FEV /FVC ≥ LLN) were found in 17% of mothers and 15% of children. A positive association between LDSA, included for the first time in this type of epidemiological study, and lung function was observed, indicating LDSA is a superior metric compared to PM to assess effects of PM on lung function. HAP demonstrated a moderate association with subnormal lung function in children. The results emphasize the need to look beyond mass-based PM metrics to assess fully the association between HAP and lung function.

“…When their analysis was restricted to lifelong non-smokers, airflow obstruction was also more common in the biomass smoke exposed group (5.2% vs 1.8%, p=0.004). Similarly, Mukherjee et al 27 compared 681 non-smoking women from eastern India who cooked exclusively with biomass (wood, dung and crop residues) with 438 age-matched women from similar neighbourhoods who cooked with liquefied petroleum gas (LPG) and reported that airflow obstruction was diagnosed in 4.6% of biomass users, as compared with only 0.9% of LPG users. In contrast, Obaseki et al 28 reported that there was no association between chronic airway obstruction and the use of firewood or coal for cooking or heating in Nigeria.…”

Background:Chronic obstructive pulmonary disease (COPD) is associated with a high degree of mortality and morbidity around the world with the burden of the disease being more in the developing countries. In the Indian context data is limited. This study was carried out to determine the predictors of outcome in patients admitted with acute exacerbation of COPD in a rural Tertiary Care Center in the state of Kerala.Materials and Methods:This was a prospective cohort study. Patients admitted with acute exacerbation of COPD in the Intensive Care Unit between August 2013 and July 2014 was included in the study. Sociodemographic data, clinical variables, and investigations were collected. Mortality with respect to relevant risk factors was compared using Kaplan–Meier method and Cox proportional hazard model.Results:Seventy patients were enrolled in the study of whom 58 (82.9%) were above the age of 60 years. Majority of the patients (87.1%) were males. Tobacco smoking was the main risk factor in them. All the females had a history of exposure to biomass fuel in the form of firewood; none of them were smokers. Majority of patients (80.0%) had a history of one or more co-existing illnesses. Anemia was found to be an independent risk factor for mortality (adjusted hazard ratio: 3.167, 95% confidence interval: 1.516–6.616). Risk factors for poor outcome in COPD patients reported from other centers in India were not found to be relevant in this study.Conclusions:Anemia could be an independent risk factor for mortality in COPD patients. India already has a high prevalence of iron deficiency anemia especially in the rural area and in the geriatric population. Henceforth, family practitioners and primary care physicians may remain vigilant regarding the development of anemia in their COPD patients and institute remedial measures without delay. Futhermore, the wide variation reported in the predictors of outcome of COPD along with the finding of this study calls for an urgent need for more studies.

Respiratory symptoms, lung function decrement and chronic obstructive pulmonary disease in pre-menopausal Indian women exposed to biomass smoke

Abstract: Cumulative exposure to biomass smoke causes lung function decrement and facilitates COPD development even in non-smoking and relatively young pre-menopausal women.
