  2. Mental health and air pollution. Alongside effects on cardiovascular and respiratory health, there is emerging evidence that exposure to air pollutants (both indoors and outdoors) may lead to neurocognitive disorders and affect mental health (directly and indirectly) through a range of potential causal pathways (see Figs 1 and 2). 1,31–35 ...

  3. Jul 6, 2023 · There were also indications that children and adolescents might be exposed to air pollution at critical stages in their mental development making them at risk of the most severe impact and significant future mental health problems.

    Peer-reviewed articles, published on or before 10 April 2020, will be retrieved using the following databases: Africa-Wide, CINAHL, ERIC, PsycARTICLES, and PsycINFO (all via EBSCOhost platform); MEDLINE (via Web of Science Clarivate Analytics); PubMed; Scopus (which includes contents of Embase); Web of Science Core Collection; and SciELO Citation I...

    The search strategy (see Supplemental File 2) was developed by author LS1, a librarian working in South Africa, and tested by LS2, a research assistant working in the UK. No date or language limits will be imposed, but the search will be limited to scholarly/peer-reviewed journal publications. The terms listed in the search strategy will be searche...

    Data management

    Articles meeting the search strategy will be populated into EndNote and screened for duplicates. Once duplicates have been removed, the records will be exported to Zotero, a software programme that allows citations to be formulated as title and abstract.

    Selection process

    The first 50 citations (title and/or abstract) will be independently screened by 11 of the review authors (LT, YAV, CB, MECL, GPA, MAO, LG, LL, IM, AT, KH) and results compared via consensus discussion (see Saldana ). This will support reviewer familiarity with the inclusion/exclusion criteria and calibrate application of the criteria. Thereafter, the remaining citations will be divided into five sets. Each set will be independently screened by at least 2 reviewers. Titles/abstracts that...

    Data collection process

    Data extraction will be guided by a data-charting form that will be developed by LT and KH and calibrated by all reviewers (using 10 of the eligible articles). The data-charting form will correspond to the items for which data will be sought (see the ‘Data items’ section). At least 2 reviewers will independently extract data from each eligible article. In instances of reviewer disagreement about extracted data, LT and KH will arbitrate. If necessary, study authors will be approached to clarif...

    The primary outcomes will be evidence (or not) of symptoms of (i) neurodevelopmental disorders; (ii) disruptive, impulse-control, and conduct disorders; (iii) depressive disorders; (iv) anxiety or post-traumatic stress disorders; (v) substance disorders; or (vi) schizophrenia spectrum disorders. Each of the aforementioned constitutes a cluster of d...

    Two review authors will independently assess the risk of bias in the included quantitative studies using the Scottish Intercollegiate Guidelines Network (SIGN) methodology checklist . This checklist includes 14 items, of which 12 assess research biases, including in selection, performance, attrition, and detection. The two review authors will evalu...

    Because we anticipate that studies will not be sufficiently homogenous to accommodate meta-analyses, the results will be tabulated and narratively synthesized. We will conduct our data synthesis according to the Synthesis Without Meta-analysis (SWiM) guidelines from Campbell et al. . In line with SWiM guidelines, we will include a table explaining ...

    Meta-bias includes both the selective reporting of outcomes due to their significance, magnitude, or direction and publication bias . To assess meta-biases due to selective outcome reporting, we will (1) evaluate whether studies have associated protocols and whether those protocols were published prior to the recruitment of participants; (2) look f...

    To assess confidence, we will apply the Grading of Recommendations Assessment, Development and Evaluation (GRADE ), which is a widely used and transparent framework for summarizing confidence in evidence presented. GRADE involves a separation between judgements of quality of the evidence and the strength of the recommendations. Quality of evidence ...

  4. Apr 12, 2023 · Though less well-understood, there is substantial evidence that air pollution also impacts mental health. Past research has associated air pollution with higher levels of stress, psychological distress, increased risk of dementia and Alzheimer’s and depression.

  5. We examined the association of air and noise pollution exposure from pregnancy to 12 years of age with mental health problems from ages 13 to 24 years. Based on previous evidence, we focused on psychotic experiences (eg, subclinical hallucinations and delusions), depression, and anxiety.

  6. Mar 14, 2022 · Washington – Exposure to ozone from air pollution has been linked to an increase in depressive symptoms for adolescents over time, even in neighborhoods that meet air quality standards, according to new research published by the American Psychological Association.

  7. This scope review contributes to the evidence of the health effects of short- and long-term exposure to urban air pollution, leading to a range of harmful effects on children’s and adolescents’ cognitive, respiratory, and cardiovascular health.
