483 A NOVEL APPROACH IN PREDICTING THE 10-YEAR RISK OF CARDIOVASCULAR DISEASE AMONG CANADIANS AND ITS ASSOCIATION WITH DIETARY INTAKE S Setayeshgar, H Vatanparast, SJ Whiting Saskatoon, Saskatchewan BACKGROUND:
Cardiovascular disease (CVD) is the second cause of death in Canada with 21% of all deaths. Initial risk assessment completed by Framingham Risk Score (FRS) is recommended to estimate the percent of 10-year risk of developing fatal and nonfatal CVD. Based on the 2012 update of the Canadian Cardiovascular Society recommendations, two modifications were added to FRS: FRS is doubled in subjects 30-59y who have CVD present in a first-degree relative before 55y for men and 65y for women; and cardiovascular age is calculated for each individual. Thus our aim is to evaluate differences for Canadians in 10-year CVD risk obtained from traditional FRS and modified FRS, at the population level. Further, we evaluated the association between dietary intake and 10-year CVD risk controlling for potential covariates. METHOD: Canadian Health Measures Survey data cycle 1 was used among Canadian aged 30-74y. Descriptive statistics and logistic regression analysis were conducted using STATA SE 11. Data were weighted and bootstrapped to take into account the population variance. RESULTS: Using modified FRS for predicting percent 10-year risk of CVD significantly increased the mean of the risk compared to the traditional approach, 8.66%0.35 versus 6.06%0.18. Similarly, the distribution of Canadians in low (<10%), and high risk (20%) categories of CVD displayed significant difference between traditional and modified RFS: 79.6% versus 67.3% (low risk) and 4.5% versus 13.7% (high risk), respectively. The risk was significantly greater among males (11.9% vs. 5.4%), less educated (

S305 BACKGROUND: Increased cardiovascular risk factor (CRF) awareness in the general population is a defined objective of health care campaigns and public health policy in the Western world. Cardiovascular disease remains a major cause of morbidity and mortality, with disproportionate distribution amongst various ethnic populations. Furthermore, recent trends demonstrate greater ethnic diversity in many countries affected by a high cardiovascular disease morbidity and mortality. However, there is limited information on CRF prevalence and awareness among diverse ethnic groups. METHODS: A cross-sectional survey was administered to 4682 subjects presenting to an urgent care clinic serving an ethnically diverse metropolitan population. CRF awareness was determined for hypertension, smoking, hyperlipidemia, diabetes, obesity, sedentary lifestyle, and physical inactivity. We compared CRF awareness and prevalence among Caucasian, South Asian, East Asian, Black, and other ethnic groups, using Caucasians as the reference for comparative analyses. Analyses were adjusted for age, gender, education and length of residence in Canada. RESULTS: Response rate was 68%. Ethnicity status was available for 3102 of 3189 (97%) survey respondents. The mean age of the study population was a 3714 years with 44% males and 56% females. The CRF prevalence and awareness profile of the study population are shown in the table 1 and table 2 respectively. The CRF prevalence trended non-significantly towards greater burden amongst ethnic groups compared to Caucasians, except for significantly lower levels of smoking in ethnic groups. Prevalence was significantly greater amongst South Asians for most risk factors and amongst various ethnic groups for diabetes, sedentary lifestyle and obesity. Awareness was significantly lower for most CRF examined across all ethnic groups compared to Caucasians. CONCLUSION: While the burden of CRF prevalence varied amongst ethnicities, there was marked disparity for CRF awareness across ethnic subgroups. These findings highlight the need for specifically designed interventions to improve CRF awareness and lower cardiovascular disease burden in an ethnically diverse population.
