To assess whether exposure to increased levels of outdoor air pollution is associated with psychological depression, six annual iterations of the Canadian Community Health Survey (n ≈ 127,050) were used to estimate the prevalence of a major depressive episode (2011–2014) or severity of depressive symptoms (2015–2016). Survey data were linked with outdoor air pollution data obtained from the Canadian Urban Environmental Health Research Consortium, with outdoor air pollution represented by fine particulate matter ≤2.5 micrometers (μm) in diameter (PM2.5), ozone (O3), sulfur dioxide (SO2), and nitrogen dioxide (NO2). Log-binomial models were used to estimate the association between outdoor air pollution and depression, and included adjustment for age, sex, marital status, income, education, employment status, urban versus rural households, cigarette smoking, and chronic illness. No evidence of associations for either depression outcomes were found. Given the generally low levels of outdoor air pollution in Canada, these findings should be generalized with caution. It is possible that a meaningful association with major depression may be observed in regions of the world where the levels of outdoor air pollution are greater, or during high pollution events over brief time intervals. Future research is needed to replicate these findings and to further investigate these associations in other regions and populations.

Background: The ocular surface is separated by a thin layer of tear film from outdoor air pollutants making individuals exposed to outdoor air pollution prone to various ocular surface disorders. The aim of this study was to determine the magnitude of ocular surface disorders symptoms among traffic police officers of Kathmandu, Nepal. Methods: Two hundred traffic police officers working at different traffic police office branches of Kathmandu, Nepal were invited to the police headquarters for eye and vision examination. Among them, 91 individuals (95% males) completed the ocular surface disease index (OSDI) questionnaire and underwent Schirmer’s I tear test. Results: Symptoms of ocular surface disorders were reported by over 80% of the individuals. Approximately two fifths of the individuals (38%) reported severe symptoms.  Only 17% of the individuals’ tear secretion was found to be below normal using the Schirmer’s tear test.  There was no association between the OSDI score and Schirmer’s tear test scores (r = 0.008, p = 0.94). A weak but significant relationship was observed between the OSDI score and job duration (r=0.21,p = 0.04). Individual exposed to outdoor air pollution for more than 10 years had higher odds of reporting ocular surface complaints as compared to those who were exposed for less than 10 years (OR = 3.94, p = 0.02). Conclusion: Ocular surface disorder symptoms are common among traffic police officers of Kathmandu, Nepal. The duration of exposure appears to significantly contribute to the increased symptoms in this vulnerable population.

The Impact

ObjectivesOutdoor air pollution is a serious environmental problem worldwide. Current systematic reviews (SRs) and meta-analyses (MAs) mostly focused on some specific health outcomes or some specific air pollution.DesignThis evidence gap map (EGM) is to identify existing gaps from SRs and MAs and report them in broad topic areas.Data sourcesPubMed, Cochrane, Scopus and Web of Science were searched from their inception until June 2018. Citations and reference lists were traced.Eligibility criteriaSRs and MAs that investigated the impact of outdoor air pollution on human health outcomes were collected. This study excluded original articles and qualitative review articles.Data extraction and synthesisCharacteristics of the included SRs and MAs were extracted and summarised. Extracted data included authors, publication year, location of the corresponding author(s), publication journal discipline, study design, study duration, sample size, study region, target population, types of air pollution and health outcomes.ResultsAsia and North America published 93% of SRs and MAs included in this EGM. 31% of the SRs and MAs (27/86) included primary studies conducted in 5–10 countries. Their publication trends have increased during the last 10 years. A total of 2864 primary studies was included. The median number of included primary studies was 20 (range, 7–167). Cohort studies, case cross-over studies and time-series studies were the top three most used study designs. The mostly researched population was the group of all ages (46/86, 53%). Cardiovascular diseases, respiratory diseases and health service records were mostly reported. A lack of definite diagnostic criteria, unclear reporting of air pollution exposure and time period of primary studies were the main research gaps.ConclusionsThis EGM provided a visual overview of health outcomes affected by outdoor air pollution exposure. Future research should focus on chronic diseases, cancer and mental disorders.

Familial Dependence

Associations between outdoor air pollution and asthma in adults are still scarce, and the underlying biological mechanisms are poorly understood. Our aim was to study the associations between 1) long-term exposure to outdoor air pollution and current asthma, 2) exhaled 8-isoprostane (8-iso; a biomarker related to oxidative stress) and current asthma, and 3) outdoor air pollution and exhaled 8-iso.Cross-sectional analyses were conducted in 608 adults (39% with current asthma) from the first follow-up of the French case–control and family study on asthma (EGEA; the Epidemiological study of the Genetic and Environmental factors of Asthma). Data on nitrogen dioxide, nitrogen oxides, particulate matter with a diameter ≤10 and ≤2.5 µm (PM10 and PM2.5), road traffic, and ozone (O3) were from ESCAPE (European Study of Cohorts for Air Pollution Effects) and IFEN (French Institute for the Environment) assessments. Models took account of city and familial dependence.The risk of current asthma increased with traffic intensity (adjusted (a)OR 1.09 (95% CI 1.00–1.18) per 5000 vehicles per day), with O3 exposure (aOR 2.04 (95% CI 1.27–3.29) per 10 µg·m−3) and with exhaled 8-iso concentration (aOR 1.50 (95% CI 1.06–2.12) per 1 pg·mL−1). Among participants without asthma, exhaled 8-iso concentration increased with PM2.5 exposure (adjusted (a)β 0.23 (95% CI 0.005–0.46) per 5 µg·m−3), and decreased with O3 and O3-summer exposures (aβ −0.20 (95% CI −0.39– −0.01) and aβ −0.52 (95% CI −0.77– −0.26) per 10 µg·m−3, respectively).Our results add new insights into a potential role of oxidative stress in the associations between outdoor air pollution and asthma in adults.

Abstract To investigate the prevalence of CSS in a general population. A large-scale cross-sectional study on 21,661 residents (7,531 men, 14,130 women) in a community in Japan was performed. CSS were assessed using Central Sensitization Inventory (CSI-A, B). Participants with a CSI-A score ≥40 was defined as having CSS. Age, sex, district, CSI-B (10 CSS-related diseases), lifestyle, and mental health factors were rated in a self-reported survey. The prevalence of CSS and its relationship with potential factors were examined by sex using descriptive and logistic regression models. The prevalence of CSS was 5.4% (95% Confidence Interval (CI) 5.1 to 5.7) in all participants. It significantly differed between men (3.6%, 95% CI 3.2 to 4.1) and women (6.3%, 95% CI 5.6 to 6.7). A CSI-A score ≥40 correlated with more than one CSI-B disease, exercise habits, sleeping hours per day, perceived stress, and resilience in both men and women. In women, age, ex-smokers, coffee intake (≥1 day per week), and alcohol intake correlated with CSS. The prevalence of CSS was 5.4% in the community examined and was higher in women than in men. CSS-related diseases and many factors correlated with CSS. The present results provide important information for future research on CSS.
