Title Outdoor light at night at residences and breast cancer risk in Canada Type Journal Article
Year 2020 Publication European Journal of Epidemiology Abbreviated Journal Eur J Epidemiol
Volume in press Issue Pages
Keywords Human Health; Breast cancer; Case-control study; Circadian disruption; Light at night; Night work; Women's health
Abstract Experimental and epidemiologic studies suggest that light at night (LAN) exposure disrupts circadian rhythm, and this disruption may increase breast cancer risk. We investigated the potential association between residential outdoor LAN and breast cancer risk. A population-based case-control study was conducted in Vancouver, British Columbia and Kingston, Ontario, Canada with incident breast cancer cases, and controls frequency matched by age in the same region. This analysis was restricted to 844 cases and 905 controls who provided lifetime residential histories. Using time-weighted average duration at each home 5-20 years prior to study entry, two measures of cumulative average outdoor LAN were calculated using two satellite data sources. Logistic regression was used to estimate the relationship between outdoor LAN and breast cancer risk, considering interactions for menopausal status and night shift work. We found no association between residential outdoor LAN and breast cancer for either measure of LAN [OR comparing highest vs. lowest tertile (DNB) = 0.95, 95% CI 0.70-1.27]. We also found no association when considering interactions for menopausal status and past/current night work status. These findings were robust to changes to years of residential data considered, residential mobility, and longer exposure windows. Our findings are consistent with studies reporting that outdoor LAN has a small effect or no effect on breast cancer risk.

Title Health consequences of circadian disruption Type Journal Article
Year 2020 Publication Sleep Abbreviated Journal Sleep
Volume 43 Issue 1 Pages
Keywords Human Health; Circadian Rhythm; Chronobiology; Sleep; Review
Abstract The circadian system is key for optimal functioning by maintaining synchrony between internal circadian rhythms, behaviors, and external cues. Many clinicians are not fully aware, however, of the far-reaching implications of the circadian system for human health. Clinical attention to circadian rhythms has largely focused on sleep disturbances. The impact of the circadian system on health is, however, much broader. Clinical diagnoses are often based on single time point assessments during the day, ignoring circadian influences on physiology. Even when time is considered, using (external) clock time ignores the large interindividual differences in internal timing.

Title Effects of artificial light at night and light pollution on human circadian rhythms Type Journal Article
Year 2019 Publication Environnement Risques Santé Abbreviated Journal
Volume 18 Issue 6 Pages 477-487
Keywords Reveiw; Human Health
Abstract Artificial light is a tangible manifestation of economic and social development, as well as a response to certain needs, especially comfort and civil and road safety. However, this use has been so associated with technological progress that its invasion of daily life has been almost imperceptible. With the recent increase in night lighting (11 million light points in 2016 according to the French Agency for the Environment and Energy Management) and the production of new lamp technologies (in particular light-emitting diodes or LEDs), societal concerns have emerged and are growing. These concerns include light pollution and the impact of blue light on human health and the environment. The scientific community has also taken up the subject, publishing in recent years a large and ever-increasing number of articles on the effects of artificial light at night on fauna and flora as well as on human health. In this review, we propose a synthesis of knowledge on human health effects of light based on scientific reports and an update of recent scientific production.

This review updates knowledge of the chronobiological effects of light at night, particularly blue light. We also briefly describe the potential beneficial effects of light on well-being.

Title Explaining seasonal fluctuations of measles in Niger using nighttime lights imagery Type Journal Article
Year 2011 Publication Science (New York, N.Y.) Abbreviated Journal Science
Volume 334 Issue 6061 Pages 1424-1427
Keywords Remote Sensing; Human Health; Cities; Emigration and Immigration; Epidemics; *Epidemiologic Methods; Humans; Light; Measles/*epidemiology/transmission; Niger/epidemiology; *Population Density; Remote Sensing Technology; *Seasons; Spacecraft
Abstract Measles epidemics in West Africa cause a significant proportion of vaccine-preventable childhood mortality. Epidemics are strongly seasonal, but the drivers of these fluctuations are poorly understood, which limits the predictability of outbreaks and the dynamic response to immunization. We show that measles seasonality can be explained by spatiotemporal changes in population density, which we measure by quantifying anthropogenic light from satellite imagery. We find that measles transmission and population density are highly correlated for three cities in Niger. With dynamic epidemic models, we demonstrate that measures of population density are essential for predicting epidemic progression at the city level and improving intervention strategies. In addition to epidemiological applications, the ability to measure fine-scale changes in population density has implications for public health, crisis management, and economic development.
