Rules are listed by order of predicted variables and support values in descendent order.

^aARM results of Minimum support 2%; minimum confidence: 60% for men, 50% for women.

^bSize is the number of lifestyle risk behaviors included in the rule. Predictors are the variables to the left of the rule, and predicted variables are those to the right of the rule.

^cThe odds ratio was adjusted for sex, age, marital status, education, occupation, income, and chronic disease status.

CS: current smoking; HD: heavy drinking; PI: physical inactivity; OB: obesity; IS: inadequate sleep; BS: breakfast skipping; FS: frequent snacking.
