“…Our finding of adverse effects of living in urban areas on lung function among elementary school children in Lanzhou city in Period 2 was in conformity with those from earlier studies (37)(38)(39), including some conducted among developing countries (37,40). An international population-based study (38) investigated the influence of childhood living environment and biodiversity indicators on lung function, reporting fewer atopic sensitization and higher FEV 1 among those with early-life farm exposure.…”

“…Another two cross-sectional cohort study, conducted among school-age children (5-15 years of age) from the capital and the rural district in Mongolia (40), reported normal FEV 1 was actually 40% higher in rural Mongolian children than in urban children. The differences observed in lung function between the rural and urban areas were also pointed by other studies (37,44) and attributed to outdoor air pollution (12), exposure to farm animals (45), farming activities (46), and allergen exposure (11). While we initially intended to consider ambient air pollution as a risk factor, it was difficult to do this in our two cross-sectional design, due to difficulties in measuring personal exposure to outdoor and indoor air pollution.…”

Lanzhou has experienced rapid urbanization, leading to changes in socioeconomic, nutritional, and household factors. These changes may affect children's lung function. Methods:Two cross-sectional studies of school-age children (6-13 years of age) from the urban (Chengguan) (Period 1 in 1996 with n=390; Period 2 in 2017 with n=192) and the suburban (Xigu) (Period 1 n=344; Period 2 n=492) district were conducted. Demographic information, household factors, and nutrition status were obtained via a questionnaire survey. Forced vital capacity (FVC) and forced expiratory volume in the first second (FEV 1 ) were measured in each period. Student's t-test analysis of variance was used to assess the differences in FVC and FEV 1 between Periods 1 and 2. Generalized linear models were used to analyze the associations between questionnaire derived factors and lung function. Analyses were done separately for girls and boys. Results:Children had significantly lower mean FEV 1 and FVC measures in Period 2 than in Period 1. This reduction was greater in children living in the urban area than those living in the suburban area. Obese children had significantly lower lung function but this was only statistically significant in Period 1. Conclusions:Children's lung function (FVC and FEV 1 ) were lower in 2017 than in 1996. Rapid urbanization may have contributed to the decline of lung function. Obesity may be a risk factor for impaired lung function in children living in Lanzhou and possibly elsewhere.

There are many benefits of breastfeeding for children, women and society but robust evidence that breastfeeding is favorable for the lung function of children is lacking. To evaluate the associations of breastfeeding with the lung function of children with no known respiratory disease and to determine which lung function parameters are related to breastfeeding, the PubMed, Embase and Cochrane Library were searched from their inception to 11 Oct 2023. Observational studies (cohort, cross-sectional or case-control designs) were included. A random-effects model was used to estimate the combined β if significant heterogeneity was detected(P < 0.05 or I2 > 50%); otherwise, the fixed-effects model was applied. The outcomes measured were forced expiratory volume in one second(FEV1), forced vital capacity(FVC), forced expiratory volume in one second to forced vital capacity(FEV1/FVC), peak expiratory flow(PEF) and other relevant lung function parameters. Compared with children with never-breastfeeding, children with ever-breastfeeding had better FEV1(β:19.34 ml; 95%CI:6.05,32.64; P = 0.004) and FVC(β:75.68 ml; 95%CI:24.40,126.97; P = 0.004). Additionally there was a slight statistical significance for FVC(β:17.45 ml; 95%CI:-0.43,35.33; P = 0.06). Furthermore, compared with the breastfed for less than 3 to 4 months, Children who had been breastfed for 3 to 4 months or more had better FEV1(β:19.86 ml; 95%CI:4.21,35.51; P = 0.01),FVC(β:31.90 ml; 95%CI:7.87,55.93; P = 0.009) and PEF(β:75.68 ml; 95%CI:24.40,126.97; P = 0.004). No significant difference was detected in FEV1/FVC between breastfed and non-breastfed children(β:-0.28; 95%CI:-0.99,0.44; P = 0.44) or between those breastfed for less than 3 to 4 months and those breastfed for more than 3 to 4 months(β:-0.48; 95%CI:-1.45,0.48; P = 0.33). This systematic review and meta-analysis revealed that being breastfed or breastfed for more than 3 to 4 months seemed to be favorable for the improvement of lung function in children aged 6–16 years. And additional high-quality evidence is needed.

Background: Air pollution in India is a serious issue with the major sources being motor vehicle emissions, thermal power stations, cooling towers, biomass burning, fuel adulteration, factory smoke, and stubble burning. Chronic exposure to ambient air pollution has obtunded effects on the development of lung function in children and detrimental effects on lung function of adults. The adverse effects of pollution on lung function increase the development of lung diseases in the future. Aims and Objective: The aim of the study was a comparison of lung function between two groups of population with different occupations, one group with outdoor occupation (high exposure) and second group with indoor occupation (low exposure). Settings and Design: It was a cross-sectional study and the sampling approach was Quota sampling. Quota sampling is a type of non-probabilistic sampling. There are certain groups of people who are particularly vulnerable to ambient air pollution because of their sustained high exposure like traffic police personnel deputed at traffic junctions, auto rickshaw driver/Taxi driver, E-Rickshaw driver plying in this area, and road side vendors this group. Low exposure group chosen were employee of offices and showrooms who are working indoor. Methods and Materials: This study was a two groups of 245 participants in each. First group with outdoor occupation and second group with indoor occupation having different level of exposure to air pollution due to their nature of occupation. Lung function parameters FEV1, FVC, FEV1/FVC, PEFR, and FEF were compared between two groups. Statistical Analysis: SPSS 26 software was used. Independent “T” test for continuous data type for different population, paired “T” test within the group, and Chi-square test for categorical data were applied. Results: Among high exposure group, 62.7% and 9.4% were found to have restrictive and normal lung function pattern, respectively. In comparison, among low exposure group, 31% and 59.5% were found to have restrictive and normal lung function pattern, respectively. Among outdoor group, there was a significant decline of lung function parameters such as FEV1, FVC, FEV1/FVC, PEFR, and FEF in comparison to indoor group. Conclusion: In this study, the lung function parameters were decreased in population working outdoor and chronically exposed to air pollution, in comparison to indoor subjects.
