dc.description.abstract	The aim of this research was to investigate whether morningness-eveningness, midpoint of sleep and average sleep duration are associated with longitude, latitude, age, gender, inhabitation and school start times in Turkish students. 15,362 students from 9 to 21 years participated in this study. Eveningness and midpoint of sleep - but not sleep duration - increased from east to west, suggesting that longitude has an effect on chronotype. Adolescents from the southern parts of Turkey were more morning oriented, suggesting an influence of climate or latitude. Morningness was negatively and midpoint of sleep was positively related with age. Females had higher morningness scores and students from urban localities showed higher eveningness and a later midpoint of sleep. (C) 2015 Elsevier Ltd. All rights reserved.
