Background Chronic exposure to heavily polluted air affects the respiratory status. Objectives: To observe the effects of air pollution on pulmonary functions of adolescent male living in urban areas of Bangladesh. Methods: This cross-sectional study was done in the department of Physiology, BSMMU. For this purpose, 60 apparently healthy adolescent male of age 13 to 18 were selected from different slum areas of Dhaka city. Sex and age matched 55 subjects were taken as control from rural area of Bangladesh. All subjects were of low socio-economic status and living in the corresponding areas since birth. In the study, Forced vital capacity (FVC), Forced expiratory volume in first second (FEV1), FEV1 /FVC % and Peak expiratory flow rate (PEFR) were estimated by VMI ventilometer on standing position. Statistical analysis was done by using “Z” test. Result: The mean measured values of FVC, FEV1, FEV1/ FVC% and PEFR were lower in the experimental group than in the control group. FVC and FEV1 were lowered significantly (p<0.05) but FEV1/FVC % and PEFR in experimental group though lowered , the result were not statistically significant. Conclusion: The results of the study reveals that pulmonary functions were lowered in urban adolescent and it was of restricted lung function type.

The Impact

IntroductionThere is growing interest in the impact of greenness exposure on airway diseases, but the impact of greenness on lung function in children is limited. We aimed to investigate the associations between greenness surrounding schools and lung function in children and whether these associations are modified by air pollution exposure.MethodsBetween 2012 and 2013, a cross-sectional survey and spirometry were performed among 6740 school children. Lung function patterns were determined as obstructive forced expiratory volume 1 s/forced vital capacity (FEV1/FVC <0.8) or restrictive (FEV1/FVC ≥0.8 but FVC <80% of predicted). School greenness was defined by Normalized difference vegetation index (NDVI) and soil-adjusted vegetation index. Nitrogen dioxide, sulphur dioxide and particular matter concentrations were assessed using a spatiotemporal model and national monitoring data. Two-level generalised linear models were used to investigate associations and interactions.ResultsOverall, an IQR in NDVI within 500 m was associated with higher FEV1 (+57 mL 95% CI 44 to 70) and FVC (+58 mL 95% CI 43 to 73). NDVI was similarly associated with 25% reduced odds of spirometric restriction (OR: 0.75, 95% CI 0.65 to 0.86). However, among children exposed to the highest compared with the lowest quartile of particulate matter, increasing NDVI was paradoxically associated with lower −40 mL FVC (95% CI −47 to –33, p interaction <0.05).DiscussionOur findings suggest that, in this study population, greening urban areas may promote lung health in low–moderate pollution areas but not in high air pollution areas. If the findings are replicated in other moderate-to-high pollution settings, this highlights a need to have a flexible green policy.

Abstract Background During pregnancy, a number of changes affecting venous blood flow occur in the circulatory system, such as reduced vein wall tension or increased exposure to collagen fibers. These factors may cause blood stagnation, swelling of the legs, or endothelial damage and consequently lead to development of venous disease. Objectives The aim of this study is to evaluate the effect of special footwear designed to improve blood circulation in the feet on venous blood flow changes observed during advancing phases of pregnancy. Methods Thirty healthy pregnant women participated in this study at 25, 30, and 35 weeks of gestation. Participants were allocated at random to an experimental group (n = 15) which was provided with the special footwear, or a control group (n = 15). At each data collection session, Doppler measurements of peak systolic blood flow velocity and cross-sectional area of the right popliteal vein were performed using a MySonoU6 ultrasound machine with a linear transducer (Samsung Medison). The differences were compared using Cohen’s d test to calculate effect size. Results With advancing phases of pregnancy, peak systolic velocity in the popliteal vein decreased significantly in the control group, whereas it increased significantly in the experimental group. No significant change in cross-sectional area was observed in any of the groups. Conclusions Findings in the experimental group demonstrated that wearing the footwear tested may prevent venous blood velocity from reducing during advanced phases of pregnancy. Nevertheless, there is a need for further investigation of the beneficial effect on venous flow of the footwear tested and its application.

Objectives: The sedentary lifestyle, physical inactivity, and unhealthy diet of Malaysian female have become important contributing factors to the rise of obesity. Studies on pulmonary function in relation to obesity are very few in Malaysia. Therefore, the study was aimed to evaluate the effect of obesity on pulmonary functions among young adult healthy female students of Shah Alam, Malaysia.Methods: A cross-sectional comparative study was conducted in a total of 100 (50 obese and 50 non-obese) adult non-smoker healthy female students aged 18–25 years. Forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), FEV1 as a percentage of FVC (FEV1/FVC%), maximum midexpiratory flow rate (FEF 25–75%), and peak expiratory flow rate (PEFR) were measured using a computerized spirometer. Body weight, height, waist circumference (WC), and hip circumference (HC) were measured.Results: The mean FVC (L), FEV1 (L), FEV1/FVC ratio, FEF 25–75% (L/s), and PEFR (L/s) of obese group were marginally lower than non-obese control group, but the differences were not statistically significant. WC and waist–hip ratio exhibited significant (p<0.05) inverse correlation with all pulmonary function measurements except FEV1/FVC%. However, body mass index had no significant correlation with any spirometric variables in studied obese females.Conclusion: There was no significant effect of obesity on pulmonary functions in the studied Malaysian females. However, abdominal obesity had more impact on the impairment of pulmonary functions than overall relative obesity.

Abstract Background The differential effects of PM2.5 fractions on children’s lung function remain inconclusive. This study aimed to examine whether lung function in asthmatic children was associated with increased PM2.5 fractions in urban areas in Nagasaki prefecture, Japan, where the air pollution level is relatively low but influenced by transboundary air pollution. Methods We conducted a multiyear panel study of 73 asthmatic children (boys, 60.3%; mean age, 8.2 years) spanning spring 2014–2016 in two cities. We collected self-measured peak expiratory flow (PEF) twice a day and daily time-series data for PM2.5 total mass and its chemical species. We fitted a linear mixed effects model to examine short-term associations between PEF and PM2.5, adjusting for individual and time-varying confounders. A generalized linear mixed effects model was also used to estimate the association for worsening asthma defined by severe PEF decline. Back-trajectory and cluster analyses were used to investigate the long-range transboundary PM2.5 in the study areas. Results We found that morning PEFs were adversely associated with higher levels of sulfate (− 1.61 L/min; 95% CI: − 3.07, − 0.15) in Nagasaki city and organic carbon (OC) (− 1.02 L/min; 95% CI: − 1.94, − 0.09) in Isahaya city, per interquartile range (IQR) increase at lag1. In addition, we observed consistent findings for worsening asthma, with higher odds of severe PEF decline in the morning for sulfate (odds ratio (OR) = 2.31; 95% CI: 1.12, 4.77) and ammonium (OR = 1.73; 95% CI: 1.06, 2.84) in Nagasaki city and OC (OR = 1.51; 95% CI: 1.06, 2.15) in Isahaya city, per IQR increase at lag1. The significant chemical species were higher on days that could be largely attributed to the path of Northeast China origin (for sulfate and ammonium) or both the same path and local sources (for OC) than by other clusters. Conclusions This study provides evidence of the differential effects of PM2.5 fractions on lung function among asthmatic children in urban areas, where the Japanese national standards of air quality have been nearly met. Continuous efforts to promote mitigation actions and public awareness of hazardous transboundary air pollution are needed to protect susceptible children with asthma.

Background: Air pollution leads to several health effects, the major systems affected were respiratory, dermatology, neurology and ophthalmology. This study is an attempt to find out various health effects of pollution, from a food factory to the nearby residents.Methods: A cross sectional comparative study was performed on 248 residents nearby a food factory, situated in rural area of Thrissur district and a comparative group of 266 participants taken 5km away from this factory.Results: Both the groups were comparable in socio-demographic profile except religion and occupation. There was no statistically significant difference (p>0.05) between the use of firewood in both the groups. The symptoms of major systems involved were respiratory (odds ratio 3.9, 95% CI 2.2 to 6.8), dermatological (odds ratio 18.3, 95% CI 8.3 to 40.7), neurological (odds ratio 13.5, 95% CI 4.1 to 44.7) and ophthalmological (odds ratio 5.9, 95% CI 2.6 to 13.6). The major symptoms complained by them were pruritus (32.7%), skin lesions (17.7%), breathlessness (16.9%), itching eye (13.3%) watering from eye (11.7%) and headache (11.3%). All these symptoms among the case group compared to control group were very high and these associations were highly statistically significant (p<0.001).Conclusions: This study showed an increased occurrence of adverse health effects among the individuals who were residing near the food factory. Therefore this study points out the possibility of environmental pollution (mainly air pollution) as a main factor for the increased prevalence of symptoms among those who reside nearby the factory.

Anxiety was the barrier mostly chosen by women for not performing mammography examination. Music was perceived as an effective method in reducing these barriers. Thus, this study was done to investigate how music would influence anxiety level among women undergoing mammogram screening. A cross-sectional descriptive study was conducted at randomly selected private hospitals around Klang Valley. The ’State-Trait Anxiety Inventory’ form was used to measure the level of anxiety. Respondents were categorized into two groups, which are control (no music) and experimental (with music) groups. Descriptive analysis was used to determine the anxiety level and T-test analysis were used to compare the anxiety level between both groups. A total of 60 respondents participated in this study in which 30 (50.0%) were in a control group and 30 (50.0%) were in the experimental group. Mean age of respondents were 53.5 (±12.7) years. The anxiety level is high in women who underwent mammography with no music (60.0%) as compared those with music (53.3%), although the difference is not significant (p>0.05). Music intervention has potential in reducing anxiety level during mammography examination.

Background: Moderate-to-vigorous physical activity (MVPA) offers many health benefits for preschoolers (2.5–5 y). In childcare, MVPA is predominantly accumulated outdoors, with higher rates purported among children within the first few minutes outside. The Supporting Physical Activity in the Childcare Environment intervention included shorter, more frequent outdoor play sessions; this study sought to explore children’s activity levels during various outdoor play schedules. Methods: During the final week of the Supporting Physical Activity in the Childcare Environment intervention, preschoolers wore an Actical™ accelerometer for 5 days during childcare and staff logged outdoor times. Separate linear mixed effects models were run to explore the effect of the intervention on preschoolers’ physical activity (total and MVPA) and sedentary time during outdoor play. Sex was entered as an interaction effect. Results: Preschoolers (n = 292) were significantly more active in the first 10 minutes outdoors compared with remaining time (P < .0083). For total outdoor time, children in the experimental group engaged in significantly less sedentary time than those in the control group (P < .017), and experimental group boys and girls engaged in higher MVPA than boys and girls in the control group (P < .017). Conclusions: Findings support scheduling more frequent outdoor play sessions in childcare to increase physical activity participation among young children.
