People\r\nwith earlier chronotypes usually get up earlier and are more active in the morning than\r\nthose with later chronotypes. Chronotype has been found to vary across countries, and\r\nresearch finds that within countries a later chronotype is correlated with worse health\r\noutcomes. This study examines chronotype\u2019s effect on people\u2019s physical and mental\r\nhealth levels across different countries. We recruited 5128 participants from 20 countries\r\nover six continents, with approximately 250 participants in each country. Participants\r\ncompleted the survey in a two-week window before and after the autumn equinox,\r\nreporting their chronotypes, mental health levels, physical health levels, and depression\r\nlevels. We used multilevel modeling to study the effect of chronotype on people\u2019s health\r\noutcomes within and between countries. We found that within countries, people with\r\nchronotypes that are later than the corresponding country\u2019s average tend to have lower\r\nphysical and mental health outcomes. However, the analysis of between-country effects\r\ndid not show any relationship between chronotype and people\u2019s health outcomes. Our\r\nstudy\u2019s findings highlight the importance of cultural fit in the relationship between chronotype and health level, demonstrating that people\u2019s chronotypes are most relevant\r\nfor predicting people\u2019s health in comparison with their own countries\u2019 averages.","language":"en"},{"key":"dc.language.iso","value":"eng","language":"en"},{"key":"dc.relation.ispartofseries","value":"University of British Columbia.
