“…Research shows similar patterns for schoolchildren and adolescents (Gradisar et al, 2011; Liu et al, 2005). Adults from East and Southeast Asia (Dong et al, 2018; Ryu et al, 2011; Tang et al, 2017; Thichumpa et al, 2018; Um & Um, 2015; Wang et al, 2020; Wu et al, 2018), Central and Southern America (Carrillo‐Larco et al, 2014; Lima et al, 2012; Neutzling et al, 2020; Soldatos et al, 2005), Sub‐Saharan Africa (Ade et al, 2021; Peltzer, 2017; Soldatos et al, 2005), The Middle East (Asghari et al, 2012; Chami et al, 2020), and urban regions in North America (Grandner, Smith, et al, 2015) are more likely to report sleep of poor quality (range 28%–50%, generally higher in rural areas) and short duration (range 12%–39%, generally higher in metropolitan urban areas) than adults residing in Europe, Japan, Australia and non‐urban regions in North America (Adams et al, 2017; Doi et al, 2001; Kocevska et al, 2021; Lakerveld et al, 2016; Liu et al, 2000). In most Western countries, the average self‐reported sleep duration (from ~7 h/night in Japan to 8.5 h/night in Portugal) and indicators of poor sleep quality (range 9%–30%, depending on the indicator assessed) are relatively comparable between populations (Adams et al, 2017; Doi et al, 2000; Groeger et al, 2004; Kocevska et al, 2021; Kronholm et al, 2006; Soldatos et al, 2005).…”
