“…Although the health effects of air pollution including mortality, morbidity, symptoms and physiological functions have been previously reported in Mongolia (Nakao et al 2016 ), the concept of HR-QoL, which refers to the individual’s perception of well-being, should also be considered as an adverse health outcome (American Thoracic Society 2000 ). The effects of air pollution on the HR-QoL in adults with CRD were previously reported (Miravitlles et al 2014 ; Jones et al 2016 ).…”

BackgroundThis study was performed to investigate the effects of air pollution and seasonality on the respiratory symptoms and health-related quality of life (HR-QoL) of outpatients with respiratory diseases in Ulaanbaatar, Mongolia. Subjects were outpatients who visited the hospital with chronic obstructive pulmonary diseases (COPD) or bronchial asthma (BA) in March. Their symptoms and HR-QoL were evaluated using a questionnaire including the SF-36v2 and COOP/WONCA charts in March, May and July. PM2.5 was sampled in March and July in Ulaanbaatar, and its composition was analyzed.ResultsPatients with COPD or BA showed higher prevalence of respiratory symptoms than the control subjects in each month. For HR-QoL, all subscales worsened in the patients than in the control group in March. Although the HR-QoL of the COPD and control groups were not significantly changed through the surveys, some subscales of the BA group showed remarkable improvement in July as compared to March. Daily means of PM2.5 in March were significantly higher than those in July. Carbon and ionic component concentrations, except for magnesium and calcium ions, were significantly higher in March than July. Mass concentrations of some metallic components were also significantly higher in March than July. The percentage of nitrate ion in PM2.5 was significantly higher in March when compared to that in July.ConclusionsThese results suggested that the symptoms in the COPD and BA groups were caused by the disease, and the association with air pollution or seasonality remained unclear. However, the effects of air pollution and seasonality on the HR-QoL were significant in the patients with BA.Electronic supplementary materialThe online version of this article (doi:10.1186/s40064-016-3481-x) contains supplementary material, which is available to authorized users.

“…The studies were started in 2010 and finished in 2015, and the participants were different each year. Subjects who agreed to participate in the present study received a self-completed questionnaire, which is the Japanese version of the questionnaire used in our previous study [22]. The questionnaire contained questions on age, gender, occupation, respiratory symptoms during last two weeks, as well as the COOP/WONCA charts (The ‘Dartmouth COOP Functional Health Assessment Charts/WONCA (World organization of Family Doctors)’).…”

Background There has been growing global concern about air pollution due to its great risk to public health. In Japan, although industrial- and traffic-related air pollution has been decreasing, concerns about particulate matter air pollution has been growing in recent years. In this study, we examined the effects of air pollution on symptoms and the health status of healthy subjects in Japan. Methods Participants ( n = 2887) who visited healthcare centers in Kumamoto or Niigata prefectures in February from 2010 to 2015 were asked to fill out a questionnaire, which was a self-completed booklet containing questions on the characteristics of participants, their respiratory symptoms, and questionnaires on their health status in February, May, and July. Generalized estimating equation analyses were performed to predict the factors associated with the symptoms and health status using two-week averages of air quality parameters obtained from 49 monitoring stations as independent variables. Results Only allergy was associated with air quality in both areas. Prevalence of the other respiratory symptoms were correlated with air quality only in Kumamoto. The health statuses including the ‘physical fitness’, ‘daily activities’, and ‘social activities’ domains were related only to time spent outdoors. The ‘overall health’ was associated with time spent outdoors and concentrations of nitrogen dioxide and suspended particulate matters (SPM) in Kumamoto, and with temperatures and SPM in Niigata. The ‘pain’ score was correlated with temperature and carbon monoxide concentration only in Kumamoto. In Kumamoto, the ‘quality of life (QoL)’ was worse in those who spent shorter hours outdoors, were exposed to lower humidity, higher concentrations of oxidants, SPM, and PM2.5, and who experienced more Asian sand dust (ASD) events. In Niigata, a worsened ‘QoL’ was associated with time spent outdoors, temperature, and SPM. Conclusions The associations between air quality and the health status was found mainly in the comprehensive domain of the health status such as ‘overall health’ and ‘QoL’. The effect of short-term exposure to larger particles, such as SPM, on health status was observed when compared to smaller particles such as PM2.5 and gaseous pollutants.

“…All data collection staff will be trained on managing research questionnaires and evaluating body measurements, in accordance with the standard research programs to ensure the high quality and consistency of the questionnaire. The quality of life evaluation scale Short-Form Health Survey 36 (SF-36) [33], COOP/WONCA charts [34], and gastrointestinal symptom rating scale (GSRS) will be completed before entering the group, after the final treatment, 12 weeks after the final treatment, and 24 weeks after the final treatment. The respiratory and circulatory disease follow-up records will be acquired 12 weeks after treatment and 24 weeks after final treatment.…”

Background Extended exposure to high concentrations of PM2.5 changes the human microbiota profile, which in turn may increase morbidity and mortality due to respiratory system damage. A balanced microecosystem is crucial to human health, and certain health-related problems may be addressed by effective microecosystem regulation. Recent studies have confirmed that probiotics may reduce the incidence of respiratory diseases. However, few studies have investigated probiotic treatment outcomes in subjects exposed to high concentrations of PM2.5. Methods This study is designed as a prospective, randomized, participants- and assessor-blinded, placebo-controlled trial. One hundred and twenty eligible volunteers recruited from October 2019 to July 2020 in downtown Chengdu, China, will be treated with either probiotics or placebo over 4 consecutive weeks. The primary outcome will be 16SrRNA sequencing assay data from nasal and intestinal secretions. Secondary outcomes will be pulmonary function, score on a gastrointestinal symptom rating scale, COOP/WONCA charts, and the Short-Form Health Survey 36 for quality of life. Results will be analyzed to assess differences in clinical efficacy between groups. Six-month follow-up examinations will evaluate the long-term value of probiotics on cardiovascular and respiratory disease end-point events. Discussion We will explore the characteristics of nasal and intestinal microbiota in a population with high exposure to PM2.5. Probiotics and placebo interventions will be tested for efficacy in microbial balance regulation, effects on lung and physical functions, and quality of life improvement. This study is expected to provide reliable evidence to support the widespread promotion of probiotics in clinical practice for the protection of individuals with high exposure to PM2.5.
