Purpose: Flavonoids are dietary polyphenolic compounds with a variety of proposed beneficial cardiovascular effects, but rigorous prospective data in representative samples are limited. We assessed the association between dietary flavonoid intake and incident coronary heart disease (CHD) in a biracial cohort. Methods: Participants were 17,121 black and white, men and women, enrolled in the REGARDS study, without CHD at baseline, who completed a Block-98 food frequency questionnaire (FFQ). Total flavonoid and flavonoid subclass (anthocyanidin, flavan-3-ol, flavanone, flavonol, flavone, proanthocyanidin and isoflavone) intakes were estimated from USDA flavonoid databases. Incident CHD events were captured by participant report and adjudicated by experts. Quintiles of flavonoid intake were examined as predictors of incident CHD using Cox proportional hazards regression models. Tests for trend used the quintile medians. Results: Over a mean 6.0 years (1.9 yrs) of follow-up, 605 CHD events occurred. High flavonoid intake was associated with self-identified white race, exercise, smoking, education and income. In fullyadjusted models (including age, caloric intake, sex, race, income, education, exercise, smoking, and intake of sweets) there was an inverse association between anthocyanidin and proanthocyanidin intake and incident CHD (Q5 v Q1: anthocyanidins HR¼0.72 (0.54-0.95), p-trend¼0.01; proanthocyanidins HR¼0.68 (0.50-0.92), p-trend¼0.003). There was no association between total flavonoid or other flavonoid subclass intakes and incident CHD. There was no effect modification by sex, race or region of residence. Conclusions: Dietary anthocyanidin and proanthocyanidin intake is inversely associated with incident CHD.
Purpose: To examine the association between sleep duration and asthma among Florida high school students, and whether body mass index (BMI) is an effect modifier of the association. Methods: Cross-sectional analysis of 16728 high school students participating in the Florida Youth Risk Behavior Survey (2009- 2013). We used logistic regression to obtain odds ratios (OR) and 95% confidence intervals (CI) of the association between sleep duration and current asthma, after controlling for potential confounders, followed by stratified analyses by BMI categories. Results: Both short and long sleep durations were associated with increased odds of asthma. Compared with 7 hours of sleep per night, odds ratios (95% CI) for sleeping for 4, 5 hours, and 9 hours per night were 1.37 (1.11, 1.70), 1.37 (1.10, 1.70), and 1.39 (1.027, 1.87) respectively. Associations were stronger in overweight adolescents, with sleep durations 4 hours, 5 hours, and 9 hours resulting in OR¼1.75 (1.25, 2.72), 1.85 (1.29, 2.65), and 2.06 (1.15, 3.68) respectively. These associations were not significant in normal weight adolescents, with ORs of 1.25 (0.98, 1.59), 1.21 (0.94, 1.55) and 1.20 (0.83, 1.73) for 4 hours, 5 hours, and 9 hours of sleep respectively. Results for 6, 8, and 10 hours of sleep were non-significant. Conclusion: The association between sleep duration and asthma in adolescents is modified by BMI. Short and long sleep durations are associated with increased odds of asthma in overweight adolescents, but not in normal weight ones. Lowest odds of asthma occurred with 7-8 hours of sleep.

Predicting Emergency Department Visits for Asthma: A Poisson Regression Analyses Using Data from the 2012 Asthma Call Back Survey Albert Botchway PhD, Applied Experimental Psychology, Wiley Jenkins PhD, MPH. Southern Illinois University School of Medicine Purpose: Approximately 1.3 million visits to U.S emergency departments (ED) have asthma as the primary reason. Using the 2012 Asthma Call Back Survey (ACBS), this paper identified predictors of ED visits due to Asthma and reported incidence rate ratios for each predictor. Methods: This was a cross-sectional design relying on the Behavioral Risk Factor Surveillance System (BRFSS). The ACBS relies on the BRFSS sampling frame to collect follow-up information on BRFSS participants on asthma including ED visits. ED visits was measured by self-report. Results: About 10.42% individuals reported ED visits due to Asthma. Out of those reporting ED visits, the breakdown was: 53.26% (1 visit), 23.71% (2 visits) and 11.01% (3 visits). The health-related of quality of life model guided this study. Using Poisson regression, the results revealed that possessing knowledge on the signs of asthma attacks interestingly increased the incidence of ED visits, IRR¼1.74 (1.18-2.56). Depression led to more ED use, IRR¼1.47 (1.06-2.03). Compared to Whites, Blacks and Hispanics used the ED more frequently, IRR¼1.89 (1.18-3.03) and IRR¼1.61 (1.01-2.56) respectively. Asthmatics in urban areas used the ED at a higher rate compared to rural, IRR¼1.56 (1.39-1.81). Asthmatics who were divorced/separated/widowed had a higher incidence of ED visits compared to married individuals, IRR¼1.48 (1.04-2.11). Proportion of environmental exposures, gender, smoking status and obesity were not significant factors in predicting ED visits. Conclusions: Interestingly, knowledge of signs of asthma attack increased the incidence of ED visits. It is suggested that knowing attack signs cognitively and behaviorally prepared individuals to visit the ED.
Purpose: Chronic obstructive pulmonary disease (COPD), a progressive and nonreversible disease, is a leading cause of mortality and morbidity throughout the world. Because airway inflammation is a hallmark of COPD, it has been proposed that measuring exhaled nitric oxide, a marker of inflammation, in exhaled breath condensate could prove to be an inexpensive and efficient method to detect COPD in outpatient settings. Methods: This study used data from the National Health and Nutrition Examination Survey 2007 to 2010 to test the association between exhaled nitric oxide (eNO), COPD, and COPD severity (defined based on the GOLD standard). In addition, this study explored whether occupation modifies the association between eNO and COPD. Descriptive statistics, univariable and multivariable binary logistic Regression and proportional odds logistic regression analyses were used to analyze data from a sample size of 10,214 individuals. Results: The prevalence of COPD was 7.2%, based on self-reported physician diagnosed COPD and 11.4% based on pre-bronchodilator spirometry analysis. Whereas, the prevalence of COPD severity was 6.9% for Stage I, 4.8% for Stage II, and 0.7% for Stage III/IV. This study found no statistically significant association between eNO quartiles, COPD, and COPD severity, and occupational status did not appear to modify the association between eNO and COPD. Conclusions: The findings of this study highlight the importance of using objective measures such as spirometry in clinical settings for early diagnosis and management of COPD. The results weaken the prospect of using eNO as a biomarker for COPD.
