Binge drinking, blood pressure, and duration of physical activity as risk factors for cardiovascular disease in college students. Danielle Dubois & Jesse Stabile Morrell. Nutrition Program, Department of Molecular, Cellular and Biomedical Sciences University of New Hampshire, Durham NH, USA Introduction College students frequently participate in binge drinking behavior 1-3
. Surprisingly, studies have found a correlation between increased physical activity and greater frequency of alcohol consumption 1-3
. Binge drinking behavior may lead to long term adverse health effects in addition to alcoholism, such as heart disease 4 . Pre-hypertension is an early indicator of heart disease that can easily be obtained 5 . The risky behaviors demonstrated by college aged students provide a unique opportunity to gather data on an at risk population that may benefit from educational intervention.
Purpose
To examine the relationship of blood pressure and duration of physical activity with the incidence of self reported binge drinking in college aged students. CHANAS The College Health and Nutrition Assessment Survey is an on-going cross sectional study of a college aged cohort, 18-24 years of age, at the University of New Hampshire 6 . Students (n=5604) were recruited between 2005-2012 from an introductory nutrition course (UNH IRB# 3329, 5524). Methods • Blood pressure was measured via automated cuff following standard protocol. •Binge drinking was defined as drinking ≥5 drinks in a row for men or drinking ≥4 drinks in a row for women. Data were self reported via questionnaire. • Duration of physical activity was reported via questionnaire and categorized by none, <30, 30-59, 60-89, >90 minutes. •Pre-hypertension (PH) was defined as a blood pressure >120/85 mmHg. • Chi square tests were used to examine differences (SPSS, v.20.0). Results
Key Findings • Fifty-two percent of students reported binge drinking within the last two weeks. • Male binge drinkers tended to be more likely than non- binge drinkers to spend ≥90 min/day engaging in PA. • Female binge drinkers were more likely to spend 60-89 min/day engaging in PA vs. non-binge drinkers. • Male binge drinkers were more likely to have PH than non-binge drinkers.

Stude n ts Program # LB384. Inadequate physical activity (PA) and pre-hypertension (PH) are known risk factors for cardiovascular disease (CVD), however, their relationship with college binge drinking has not been closely examined. Data from the ongoing cross-sectional College Health and Nutrition Assessment Survey were collected between 2005-2012. Introductory nutrition students (n=5604) reported PA and drinking behavior via questionnaire; blood pressure (BP) was measured via automated cuff following standard protocol. The duration of daily PA was categorized as none, <30, 30-59, 60-89, or ≥90 min; BP was categorized as PH (≥120/85) or normotensive (<120/85). Fifty-two percent of students reported binge drinking within the last two weeks. Male binge drinkers tended to be more likely than non-binge drinkers to spend ≥90 min/day engaging in PA (37% vs 32%, p=.07). Female binge drinkers were more likely to spend 60-89 min/day engaging in PA vs non-binge drinkers (36% vs 31%, p<.01). Male binge drinkers were more likely to have PH than non-binge drinkers (59% vs 45%, p<.01); no difference in prevalence of PH among females were observed. Data suggests that binge drinking is associated with longer durations of PA in all students, and PH is more common among male students that report binge drinking as compared to those that report no binge drinking.
