ⁱ

GEE model was used to test the associations between sleep duration groups and sensitization to aero allergens;

ⁱⁱ

All subjects were divided into three groups by sleep duration tertiles (3.0 to 7.8 hours ( T1: 1^st tertile), 7.8 to 8.9 hours(T2:2^nd tertile), and 8.9 to 14.7 hours(T3:3^rd tertile));

ⁱⁱⁱ

Model 1 was adjusted with age, sex, occupation, education, cockroach at home, smoking status, and birth order;

^iv

Model 2 was further adjusted with percentage body fat besides the covariates adjusted in model1.
