Higher scores on the thrill and adventure seeking scale, social disinhibition scale, and drug and alcohol attitude scale reflect higher levels of each aspect of sensation seeking. regardless of level of acculturation (ORlowest acculturation = 1.30; 95% CI: 1.05–1.61; ORmedium acculturation = 1.66; 95% CI: 1.39–1.98; and ORhighest acculturation = 1.74; 95% CI: 1.43– 2.12), after adjusting for age, country of birth, gender, SES, and the two other sensation seeking subscales. Among the least acculturated only, higher levels of social disinhibition were associated with cigarette experimentation (OR = 1.30; 95% CI: 1.05–1.59), after adjusting for age, country of birth, gender, SES and the two other sensation seeking subscales. TAS was not a significantly associated with cigarette experimentation at any level of acculturation. In Table 5 we present the results from the logistic regression models for meeting physical activity recommen- dations stratified on level of acculturation. After adjusting
