Limited attention has been given to how insomnia is associated with BMI, particularly in subarctic regions with extreme seasonal climate and daylight differences.

We included 15,364 participants aged 40\u201365\u2009years, who had complete BMI measurements and insomnia questionnaires. Sex-stratified multiple linear regression analyses were conducted to assess the association between insomnia and BMI.
