Examining gender and the longitudinal effect of weight conscious drinking dimensions on body mass index among a college freshman cohort.

OBJECTIVE This study aims to: (1) examine gender differences for weight conscious drinking among college students accounting for the broader phenomenon (e.g. including the Alcohol Effects dimension); and (2) longitudinally examine the effect of weight conscious drinking behaviors on body mass index (BMI). Participants: United States freshmen students from eight participating universities (N= 1,149). Methods: Structural equation modeling was used to model the effect of gender on weight conscious drinking dimensions at 7-month follow-up. Results: Findings suggest a significant effect of gender on Alcohol Effects (β = -.15, SE = .05, p = .005) at 7-month follow-up among college freshmen. Weight conscious drinking dimensions predicted no significant change in BMI at 7-month follow-up among college freshmen. Conclusion: Findings contribute to weight conscious drinking theory and provide campus weight conscious drinking prevention initiatives with evidence to tailor their programming to address female tendencies to engage in compensatory strategies to enhance the psychoactive effects of alcohol.
