“…Kumar et al (2011a) have shown significant contributions to excess mortality due to the exposure to traffic-derived UFP in urban areas. Jacobs et al (2010) and Bos et al (2011) have shown that even brief exposure of healthy people to traffic UFP seems to induce some health effects. Moreover, those particles may also cause cardio-vascular damage (de Hartog et al, 2003) and could cause brain stroke when penetrating into the bloodstream and being transported to other organs (Hong et al, 2002).…”

“…The foregoing observations are further substantiated by reports indicating that BDNF is markedly downregulated among those who have completed suicide, independently of mood symptoms (112). Notable, it has been demonstrated that when exercising in air polluted conditions, specifically traffic-related air pollution, levels of BDNF are not increased compared to those exercising in a room with clean air (101). Despite exercise being known to increase BDNF this increase was only seen in those that exercised in a clean room.…”

Objective: Risk factors for suicide can be broadly categorized as sociodemographic, clinical and treatment. There is interest in environmental risk and protection factors for suicide. Emerging evidence suggests a link between environmental factors in the form of air pollution and aeroallergens in relation to suicidality. Methods: Herein, we conducted a systematic review of 15 articles which have met inclusion criteria on the aforementioned effects. Results: The majority of the reviewed articles reported an increased suicide risk alongside increased air pollutants or aeroallergens (i.e. pollen) increase; however, not all environmental factors were explored equally. In specific, studies that were delimited to evaluating particulate matter (PM) reported a consistent association with suicidality. We also provide a brief description of putative mechanisms (e.g. inflammation and neurotransmitter dysregulation) that may mediate the association between air pollution, aeroallergens and suicidality. Conclusion:Available evidence suggests that exposure to harmful air quality may be associated with suicidality. There are significant public health implications which are amplified in regions and countries with greater levels of air pollution and aeroallergens. In addition, those with atopic sensitivity may represent a specific subgroup that is at risk.

“…Specialized prospective studies measure exposure within the same subjects as the reported crashes (de Geus et al, 2012;Int Panis et al, 2011;Poulos et al, 2012) (www.pasta-project.eu). The SHAPES Study followed 1087 regular Belgian cyclists over one year, during which cyclists reported their cycling distance and crashes on a weekly basis.…”

“…Only few studies found associations between cycling-related exposure to air pollution and short-term effects on health (e.g. asthma attacks) or biomarkers in cyclists (Bos et al, 2011;Strak et al, 2010). There are no studies available that link cycling-related exposure to air pollution directly to long-term health effects, which leaves various questions open about whether and how short peak exposures during cycling translate into clinically and public health-relevant chronic diseases.…”

Cycling as a Part of Daily Life: A Review of Health Perspectives

Health aspects of day-to-day cycling have gained attention from the health sector aiming to increase levels of physical activity, and from the transport and planning sector, to justify investments in cycling. We review and discuss the main pathways between cycling and health under two perspectives -generalizable epidemiological evidence for health effects and specific impact modeling to quantify health impacts in concrete settings. Substantial benefits from physical activity dominate the public health impacts of cycling. Epidemiological evidence is strong and impact modeling is well advanced. Injuries amount to a smaller impact on the population level, but affect crash victims disproportionately and perceived risks deter potential cyclists. Basic data on crash risks are available, but evidence on determinants of risks is limited and impact models are highly dependent on local factors. Risks from air pollution can be assumed to be small, with limited evidence for cycling-specific mechanisms. Based on a large body of evidence, planners, health professionals, and decision-makers can rest assured that benefits from cycling-related physical activity are worth pursuing. Safety improvements should be part of the efforts to promote cycling, both to minimize negative impacts and to lower barriers to cycling for potential riders.
