Alcohol consumption is common on college campuses and is associated with negative consequences. Factors associated with availability of alcohol are not completely understood.To describe how proximity and density of alcohol outlets are associated with any drinking and binge drinking in students at the University of Wisconsin-Madison.Participants were full-time students enrolled in the Young Adults Eating and Active for Health, a multisite, randomized intervention that assessed a variety of health behaviors. Geographic information systems were used to calculate proximity and enumerate alcohol outlet densities. Participants were categorized as "drinkers" or "nondrinkers" based on self-reported alcohol consumption. Binge drinking was categorized as "non-binge drinker," "frequent binge drinker," and "excessive binge drinker." Analysis included regression, t tests, and chi-square tests. RESULTS. Among the 166 participants, 126 (76%) were drinkers. Among drinkers, 80 (63%) were either frequent or excessive binge drinkers. Drinkers lived closer to an alcohol outlet than non-drinkers (0.18 +/- 0.15 vs. 0.61 +/- 1.59 miles, respectively, P=0.005). Within a 1-mile walking radius, there were 47% more establishments for drinkers (153 +/- 47 compared to 104 +/- 55 outlets for nondrinkers, P0.0001). At distances of 0.10-0.25 and 0.25-0.50 miles, twice as many outlets were available to drinkers (19 +/- 19 and 43 +/- 25, respectively) compared to nondrinkers (7 +/- 11 and 20 +/- 22, respectively), P0.001. Proximity and density were hot associated with binge drinking frequency.Drinkers lived closer to alcohol outlets and had significantly more outlets available at a distance of up to 1 mile. Municipal and college administrators could consider limiting alcohol license distributions in municipalities with high alcohol consumption.

In 2005, the Cystic Fibrosis Foundation (CFF) revised the nutrition classification guidelines to eliminate the use of percentage of ideal body weight (%IBW) to define "nutritional failure"; the CFF also recommended that children with cystic fibrosis maintain a body mass index percentile (BMIp)or = 50th.We assessed the effect of the 2005 CFF nutrition classification guidelines on evaluating the performance of nutritional care practices.Data from 14,702 children reported to the 2002 CFF Patient Registry were analyzed to compare malnutrition rates in 113 cystic fibrosis centers in the United States. Nutritional failure was defined according to the 2002 CFF criteria--ie, height5th percentile, %IBW90%, or BMIp10th. "Below BMI goal" was defined according to the 2005 CFF criterion, ie BMIp50th.Eliminating %IBW resulted in a 6% reduction (from 33% to 27%) in the nutritional failure rate in the United States. The use of BMIp50th led to the classification of 57% of children as below the BMI goal. Misclassification of nutritional failure according to %IBW ranged from 1% to 16% among 113 centers and was greater in the centers with a larger proportion of tall patients. After the elimination of %IBW, one-third of centers changed to a different tertile ranking for nutritional failure rates (kappa = 0.50, moderate-to-poor agreement). More than half the centers changed to a different tertile ranking, from nutritional failure to below BMI goal (kappa = 0.22, poor agreement).Eliminating misclassification by %IBW and implementing the new BMI goal led to profound and unequal changes in malnutrition rates across cystic fibrosis centers.

It is not yet known whether early-life physical activity reduces the risk of developing breast cancer. Subgroup analyses according to menopausal status and body mass may help clarify this association. Data from a population-based case-control study of female residents of Wisconsin, Massachusetts, Maine, and New Hampshire were used to examine associations between body mass and breast cancer risk. Cases (n = 4614) were identified by each state's tumor registry; controls (n = 5817) were randomly selected from population lists. Frequency of participation in strenuous physical activity when 14-22 years of age, weight at age 18 and 5 years before interview, height, and other factors were ascertained through structured telephone interviews. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were computed using logistic regression. Reductions in postmenopausal breast cancer risk associated with strenuous physical activity were greatest for women in the fourth quartile of body mass index at age 18; the OR for women with the highest activity frequency on average (or =once/day) was 0.45 (95% CI = 0.26-0.79). Associations with frequency of activity also varied by weight change. Compared to women with no activity and little adult weight gain, frequent physical activity was associated with reduced postmenopausal breast cancer risk in women who had lost weight since age 18 (OR = 0.19, 95% CI = 0.05-0.70) or had gained little or modest amounts of weight (weight gain: first tertile, OR = 0.36, 95% CI = 0.05-0.85; second tertile, OR = 0.31, 95% CI = 0.14-0.66). Weighted MET score analyses yielded similar but less inverse results. These findings suggest that the reduced risk of postmenopausal breast cancer associated with frequent, early-life physical activity may be greatest in women who, over the adult years, either lost weight or gained only modest amounts.
