CI= confidence interval

a

adjusted for age in years as a continuous variable.

b

adjusted for age, race/ethnicity, gender and foreign birth

c

adjusted for age, race/ethnicity, gender, foreign birth and poverty

d

adjusted for age, race/ethnicity, gender, foreign birth and education

e

adjusted for age, race/ethnicity, gender, foreign birth, poverty and education

f

full model - adjusted for age, race/ethnicity, gender, foreign birth, poverty, education, metro residence, sleep, video game familiarity, smoking, alcohol use, body mass index, hypertension, and diagnosis of diabetes.

g

final model - adjusted for significant cofactors: SRTT highest quartile - adjusted for race/ethnicity, gender, education, video game use, sleep, and alcohol use. SDST highest quartile - adjusted for age, race/ethnicity, gender, poverty, education, video game familiarity, sleep, alcohol use and any smoking.

h

stratified models - adjusted for cofactors in the final model and stratified on significant interaction term - poverty index
