Results from Poisson regression analysis regarding the relationship of the countries’ latitude with the incidence and fatality of COVID-19 per 1 million population during the whole time period (1 January 2020–17 April 2021) and during the time period 1 January 2020–31 March 2021, both in the total sample, as well as according to the prevalence of overweight/obesity.

Notes: Results are presented in the form: IRR (95% CI); IRR: Incidence Rate Ratio; CI: Confidence Interval; IRRs are presented per 1o increment in the latitude; Stringency Index: A composite measure based on nine response indicators including school closures, workplace closures, and travel bans, rescaled to a value from 0 to 100 (100 = strictest).
