An Examination of Changes in Social Disparities in Health Behaviors in the US, 2003-2015

Objectives: Due to growing health disparities, federal and philanthropic agencies have emphasized reducing health disparities in their preventive health efforts.This study determined the status of disparities in health behaviors in the last 13 years in the United States.Methods: Data were obtained from the Behavioral Risk Factor Surveillance Systems in odd years (2003-2015). Health behaviors were dichotomized to reflect met fruit and vegetable (FV) consumption and physical activity (PA) recommendations, non-cigarette smoking, non-heavy drinking, and non-binge drinking.Overall and sociodemographic characteristic-specific disparities ratios for each behavior were calculated.Linear trend analyses were calculated to determine disparities change across the years.Results: Overall disparities fluctuated across the years.Linear trend analyses confirmed that education-specific and income-specific disparities' contribution to overall disparities increased for all behaviors.Sex-specific disparities' contribution decreased for all behaviors except non-cigarette smoking.Age-specific disparities' contribution decreased for all behaviors except non-binge drinking.Race/ ethnicity-specific disparities' contribution to overall disparities increased for FV and non-cigarette smoking, but decreased for the other behaviors. Conclusions: The results suggest health disparities in preventive health behaviors in the last 13 years have not improved.Tailored interventions, systemic and policy changes, and/or inclusive population efforts should be initiated to reduce disparities in preventive health for the most-divergent groups identified in the results.
