Abstract 13067: Trends and Clustering of Cardiovascular Health Metrics Among US Adolescents 1988-2010
Introduction: The American Heart Association recently published a set of 7 cardiovascular (CV) health metrics for adults and children, emphasizing the importance of preventing cardiovascular risk factors. Although cardiovascular disease risk factors have generally improved in adults, there is concern that this has not been true among adolescents.
Objectives: To examine trends, clusters, and disparities of CV health metrics among US adolescents.
Methods: Using National Health and Nutrition Examination Survey 1988-2010, including 11,233 adolescents aged 12-17 years, we estimated prevalence and mean score of CV health metrics, and examined the disparities in mean score by sex, race/ethnicity, education attainment, and Poverty-Income-Ratio (PIR). The clustering of CV health metrics was indicated if the observed-over-expected prevalence (O/E) ratio was >1.
Results: Prevalence of nonsmoking, normal total cholesterol, and consuming a healthy diet appeared to increase from 1988 through 2010, while prevalence of normal BMI and physical activity appeared to decrease, resulting in a largely unchanged distribution of overall CV health scores since 1988. The prevalence of adolescents meeting all 7 CV health metrics was low across all years examined. The O/E ratios were 1.74 (1.10-2.41) and 1.07 (1.03-1.13) among adolescents achieving either lower (0-2 metrics) or higher (6-7 metrics) numbers of CV health metrics, respectively. The disparities in adjusted mean scores of CV health metrics persisted between non-Hispanic whites and non-Hispanic blacks, families/households with >12 vs. <12 years of education, and households with a PIR of >3 vs. <3 (P<0.05).
Conclusions: The proportion of adolescents achieving all 7 CV health metrics was low, and remained unchanged during 1988-2010. The disparities in mean CV health score persisted among adolescents.
