“…Clark et al () reported increased levels of PM 2.5 with increased FEV 1 values among Honduran women. Kurti et al () found no association between lung function of adults with HAP exposure, but reported an association for children. These studies suggest that chronic exposure may have reduced the susceptibility of mothers (Clark et al, ; Regalado et al, ).…”

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.

“…4,48,50,51 Women using SBF as primary fuel showed a decline of 7.62% in FEV 1 /FVC ratio in comparison to clean fuel users. [52][53][54][55] Gupta and Kaul 56 also reported a considerable reduction in lung function values among the population dependent on SBF. Sana et al 16 summarized available studies on potential health risk associated with SBF uses and suggested to identify the chemical constituents of HAP for better understanding of biomass exposure and the onset as well as aggravation of respiratory diseases.…”

Combustion of solid biomass fuel (SBF) releases a high concentration of airborne pollutants, resulting in household air pollution (HAP). HAP is considered as a leading risk factor for the development of various respiratory diseases. The increased exposure to HAP significantly affects the health of the vulnerable population, including the women, elderly, and children who stay indoors for most of the time. Considering this, self-reported respiratory health symptoms were assessed using a standard American Thoracic Society (ATS) questionnaire, whereas lung function capacity of women using SBF, liquefied petroleum gas (LPG) and mix fuels were assessed using a cross-sectional study design. Lung function capacity was examined with help of spirometry. Results suggest that compared with LPG users, SBF and mix fuel users had a relatively high prevalence of phlegm (25.7%), cough (54%), and eye irritation (74.3%). Use of SBF was found to be associated significantly with lower forced expiratory volume in the first second of expiration (FEV1) values ( P < .01). The study concludes that women cooking with SBF and mix fuels have an impact on lung function and increased prevalence of respiratory symptoms. The findings suggest that women who cook using LPG have improved lung function and respiratory health status. Hence, it is suggested to increase the scope of clean fuel programmes such as Pradhan Mantri Ujjwala Yojana (PMUY) by identifying the barriers for the choice of clean fuel uses for household energy.

The purpose of this study was to determine: (1) whether pulmonary function is reduced, and airway reactivity is increased after recovery from COVID-19 in individuals who did not have severe illness, and (2) whether physical activity levels had any impact on pulmonary function or airway reactivity. An exploratory aim of the study was also to assess whether number of symptoms was associated with pulmonary function outcomes. The maximal flow volume loop (MFVL) was used to measure pulmonary function in individuals who had previously tested positive for COVID-19 (COV; n = 20, 23.0 ± 5.4 y) and those who had not (CON; n = 20, 23.7 ± 5.5 y) before and after a hypertonic saline challenge (HSC) designed to increase airway reactivity. Self-reported symptoms and physical activity levels (MET-minutes/week) were collected to examine their correlation with pulmonary outcomes. There were no significant differences in any pulmonary function outcomes between the COV and CON groups before or after the HSC. There were also no associations between physical activity and pulmonary function outcomes. However, among participants who reported greater than four symptoms, there was a larger decline in forced expiratory volume in one second divided by forced vital capacity (FEV1/FVC) following HSC (p = 0.035). Pulmonary function and airway reactivity are not impacted after recovery from COVID-19 in young individuals; however, it appears that the number of symptoms reported may be associated with increased airway reactivity even after recovery in young adults who were not hospitalized with the virus.
