OBJECTIVE: The authors documented the prevalence of gambling and correlates to health among undergraduates. METHODS: The authors analyzed data from a health-habit questionnaire (gambling questions included) given to students enrolled in a university-required course. RESULTS: Gambling and problems with gambling were more frequent among men than women regardless of venue. Athletes more frequently bet on sports and played games of chance, had gambling debt, and sought help for gambling than did nonathletes. More than 50% of fraternity members gambled and had a higher prevalence of gambling debt than did other men. Several gambling practices were correlated with failure to use seatbelts, driving or riding with someone under the influence, and using drugs (including cigarettes). Twice as many students who had gambling problems reported considering or attempting suicide than did those who did not report gambling problems, and gambling was correlated with depression. CONCLUSION: These results indicate that gambling is correlated with high-risk health behaviors and indicates the need for intervention for college students with gambling problems.

Mounting evidence suggests that vitamin D deficiency could be linked to several chronic diseases, including cardiovascular disease and cancer. The purpose of this study was to examine the prevalence of vitamin D deficiency and its correlates to test the hypothesis that vitamin D deficiency was common in the US population, especially in certain minority groups. The National Health and Nutrition Examination Survey 2005 to 2006 data were analyzed for vitamin D levels in adult participants (N = 4495). Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D concentrations ≤20 ng/mL (50 nmol/L). The overall prevalence rate of vitamin D deficiency was 41.6%, with the highest rate seen in blacks (82.1%), followed by Hispanics (69.2%). Vitamin D deficiency was significantly more common among those who had no college education, were obese, with a poor health status, hypertension, low high-density lipoprotein cholesterol level, or not consuming milk daily (all P < .001). Multivariate analyses showed that being from a non-white race, not college educated, obese, having low high-density lipoprotein cholesterol, poor health, and no daily milk consumption were all significantly, independently associated with vitamin D deficiency (all P < .05). In summary, vitamin D deficiency was common in the US population, especially among blacks and Hispanics. Given that vitamin D deficiency is linked to some of the important risk factors of leading causes of death in the United States, it is important that health professionals are aware of this connection and offer dietary and other intervention strategies to correct vitamin D deficiency, especially in minority groups., (Copyright © 2011 Elsevier Inc.

Cross-sectional data from the Epidemiology of Diabetes Complications Study were used to examine the relationships between waist to hip circumference ratio (WHR) and the presence of diabetes complications in IDDM adults ages 18-45 years (N = 586). Significantly higher WHRs were observed among both genders with proliferative retinopathy or peripheral vascular disease and only among males with either neuropathy or nephropathy compared to those free of these complications. Logistic regression to determine the strength of association between WHR and each complication demonstrated that although WHR was significantly related to each complication (except nephropathy among females), WHR was only independently related to neuropathy in males and PVD in females in the final model when hypertension, LDL- and HDL-cholesterol and fibrinogen were included. These findings suggest that WHR acts as a marker of risk for diabetes complications mainly through an influence on other complication risk factors.

The role of waist-to-hip ratio (WHR) in the metabolic disturbance of IDDM has not been widely explored. Cross-sectional data from the Epidemiology of Diabetes Complications Study were used to examine the associations between WHR and risk factors for IDDM complications such as lipid or lipoprotein levels, blood pressure and fibrinogen. A total of 586 adults (greater than or equal to 18 years of age) were examined. WHR was calculated as the mean of duplicate waist circumference measurements made at mid-point between the iliac crest and the lower costal margin in mid-axillary line divided by the mean of duplicate maximum hip measures. WHR was positively correlated with total cholesterol, LDL-cholesterol, triglycerides, systolic and diastolic blood pressure and fibrinogen univariately for both sexes. WHR was negatively correlated with HDL-cholesterol. These correlations remained significant after adjustment for age among females and became less strong, although still significant, for males. The independent effects of WHR to these IDDM risk factors, assessed by multiple linear regression, indicated WHR was related to adverse lipid and lipoprotein levels, but not to fibrinogen or blood pressure. These findings underscore the importance of targeting intervention to IDDM individuals who have a high WHR to reduce known risk factors for IDDM complications especially those for cardiovascular disease, and is consistent with the hypothesis that insulin resistance may have a role to play in IDDM complications.

To determine the extent to which cholesterol measured in childhood is predictive of values in adulthood, the investigators conducting the second follow-up of the Beaver County Lipid Study tracked the cholesterol values of 295 adults who had initially participated as children (ages 11 to 14 years) in a countywide school screening program. The follow-up study was conducted 16 years after the initial study, when the participants had reached a mean age of 28 years. The overall correlation (r) between baseline (1972-1973) total cholesterol values and the values found at the present follow-up was 0.44 (p less than 0.0001). Women had a higher correlation (r = 0.51) than men (r = 0.38). In addition, the efficacy of childhood screening for cholesterol levels was assessed by considering currently recommended borderline values (greater than 175 mg/dl (4.6 mmol/L) for children and greater than 200 mg/dl (5.2 mmol/L) for adults) as a "positive" test result. The sensitivity of screening at age 12 years for predicting elevated adult total cholesterol concentrations was 63%, specificity was 67%, and the predictive value of a positive test result was 47%. Comparison of false-positive results (above the borderline cutoff point as a child but not as an adult) and false-negative results (below the borderline cutoff point as a child but above it as an adult) showed that male subjects with false-positive results smoked significantly less than those with false-negative results (p less than 0.05) and had a greater improvement during the preceding 7 years in cholesterol-lowering dietary practices (p less than 0.01). Female subjects with false-positive results smoked significantly less than those with false-negative results (p less than 0.05), were less overweight (p less than 0.05), and had a lower prevalence of oral contraceptive use (p less than 0.01). These results support the potential value of screening for hypercholesterolemia in childhood on a population basis. Although some subjects were misclassified as a result of childhood screening, some of this misclassification was associated with adopting changes that a screening and intervention program would be designed to promote--nonsmoking, weight control, and a prudent diet.
