“…Knowing where people are can give insights into their exposure to different attributes of the environment (e.g. air pollution, noise, greenness) and related health effects (Seeger et al, 2007;Dons et al, 2013;Bekö et al, 2015;Dewulf et al, 2016). Knowing where people are physically active (in terms of location or greenness) can also provide policy makers with insights into people's needs.…”

Physical activity is an important facilitator for health and wellbeing, especially for late middle-aged adults, who are more susceptible to cardiovascular diseases. Physical activity performed in green areas is supposed to be particularly beneficial, so we studied whether late middle-aged adults are more active in green areas than in non-green areas and how this is influenced by individual characteristics and the level of neighbourhood greenness. We tracked 180 late middle-aged (58 to 65 years) adults using global positioning system and accelerometer data to know whether and where they were sedentary or active. These data were combined with information on land use to obtain information on the greenness of sedentary and active hotspots. We found that late middle-aged adults are more physically active when spending more time in green areas than in non-green areas. Spending more time at home and in non-green areas was found to be associated with more sedentary behaviour. Time spent in non-green areas was found to be related to more moderate-to-vigorous physical activity (MVPA) for males and to less MVPA for females. The positive association between time spent in green areas and MVPA was the strongest for highly educated people and for those living in a green neighbourhood. This study shows that the combined use of global positioning system and accelerometer data facilitates understanding of where people are sedentary or physically active, which can help policy makers encourage activity in this age cohort.

“…41 Daily mass-time ratio, the proportion of the integrated exposure attributable to each microenvironment divided by the fraction of time spent in that microenvironment, 35 was also created for each participant: The limit of detection for the ambient CO monitor was 0.5 ppm, and all hourly average values below the LOD were replaced by 0.25 ppm.…”

The Fort Collins commuter study: Variability in personal exposure to air pollutants by microenvironment

et al. 2019

This study investigated the role of microenvironment on personal exposures to black carbon (BC), fine particulate mass (PM2.5), carbon monoxide (CO), and particle number concentration (PNC) among adult residents of Fort Collins, Colorado, USA. Forty‐four participants carried a backpack containing personal monitoring instruments for eight nonconsecutive 24‐hour periods. Exposures were apportioned into five microenvironments: Home, Work, Transit, Eateries, and Other. Personal exposures exhibited wide heterogeneity that was dominated by within‐person variability (both day‐to‐day and between microenvironment variability). Linear mixed‐effects models were used to compare mean personal exposures in each microenvironment, while accounting for possible within‐person correlation. Mean personal exposures during Transit and at Eateries tended to be higher than exposures at Home, where participants spent the majority of their time. Compared to Home, mean exposures to BC in Transit were, on average, 129% [95% confidence interval: 101% 162%] higher and exposures to PNC were 180% [101% 289%] higher in Eateries.
