Residential Light and Risk for Depression and Falls: Results from the LARES Study of Eight European Cities

Abstract

Objectives. We examined the relationship between self-reported inadequate residential natural light and risk for depression or falls among adults aged 18 years or older.Methods. Generalized estimating equations were used to calculate the odds of depression or falls in participants with self-reported inadequate natural residential light vs. those reporting adequate light (n6,017) using data from the World Health Organization's Large Analysis and Review of European Housing and Health Survey, a large cross-sectional study of housing and health in representative populations from eight European cities.Results. Participants reporting inadequate natural light in their dwellings were 1.4 times (95% confidence interval [CI] 1.2,1.7) as likely to report depression and 1.5 times (95% CI 1.2, 1.9) as likely to report a fall compared with those satisfied with their dwelling's light. After adjustment for major confounders, the likelihood of depression changed slightly, while the likelihood of a fall increased to 2.5 (95% CI 1.5, 4.2).Conclusion. Self-reported inadequate light in housing is independently associated with depression and falls. Increasing light in housing, a relatively inexpensive intervention, may improve two distinct health conditions.

Chronotyp und Depression bei Jugendlichen – ein Review

“…Studien zur Validierung des MEQ zeigten, dass der Peak der Körperkerntemperatur (Bailey & Heitkemper, 2001;Griefahn, Künemund, Bröde, & Mehnert, 2001;Horne & Ostberg, 1976;Ishihara & Miyasita, 1987), der Cortisol-Ausschüttung (Bailey & Heitkemper, 2001) als auch der Zeitpunkt der abendlichen Melatonin-Ausschüttung (Griefahn et al, 2001) (Murray & Lopez, 1996) und Jugendliche besonders späte Chronotypen sind (Roenneberg et al, 2004 Typische Symptome der Depression wie Interessensverlust und Antriebslosigkeit gehen häufig mit sozialem Rückzug einher (Gotlib, 1992;Hagerty, Williams, Coyne, & Early, 1996). Diese Zurückgezogenheit führt meist dazu, dass Patienten seltener ihre Wohnung verlassen und sich so weniger Tageslicht aussetzen (Brown & Jacobs, 2011;Espiritu et al, 1994;Haynes, AncoliIsrael, & McQuaid, 2005). Dies bedeutet, dass weniger helles Licht auf die Retina auftrifft und an die "Hauptuhr" im Nucleus suprachiasmaticus weitergeleitet wird -die innere Uhr wird weniger mit dem 24-Stunden Licht-Dunkel-Wechsel synchronisiert (Roenneberg, Hut, Daan, & Merrow, 2010).…”

Fatores ambientais e risco de quedas em idosos: revisão sistemática

“…Nos estudos analisados, a prevalência de quedas no último ano em idosos da comunidade variou entre 11 e 42%, [15][16][17][18][19][20] sendo observada menor prevalência (11% a 21%) nos estudos de base populacional. 16,17,20 Dos dez artigos incluídos no presente estudo, sete avaliaram a ocorrência de quedas tanto em ambientes interno como externo, 15,16,[18][19][20][21][22][23] enquanto um analisou as quedas em ambiente externo 24 e um dentro do domicílio.…”

The Physiological and Psychological Effects of Windows, Daylight, and View at Home: Review and Research Agenda

“…WHO's Large Analysis and Review of European Housing and Health Survey, covering eight cities across Europe, provided the source data for an analysis by Brown and Jacobs (2011), who found that individuals who reported inadequate natural light in their homes were at greater risk for depression and falls.…”
