Utilizing Genomics through Family Health History with the Theory of Planned Behavior: Prediction of Type 2 Diabetes Risk Factors and Preventive Behavior in an African American Population in Florida

Abstract

Aim: African Americans are disproportionately affected by type 2 diabetes. The purpose of this study was to assess to what extent African Americans' knowledge and awareness of family health history and related risk factors for developing type 2 diabetes influence their likelihood of adopting a preventive behavior.

Methods: This study employed an anonymous pencil-and-paper, self-administered survey consisting of two sections. Section 1 was a modified version of the US Surgeon General's Family Health History Initiative and the American Diabetes Association Diabetes Risk Factor Survey. Section 2 of the survey was based on the constructs of the theory of planned behavior. Over 394 African American participants completed the survey.

Results: 'Perceived behavioral control' was the strongest predictor of 'likelihood of adopting preventive behavior'. Participants were aware of their family history as a risk factor for type 2 diabetes, but it was not a significant predictor of behavior modifications based on that knowledge.

Conclusion: The lack of perceived risk in this population shows the importance of not only knowing one's risk factors but translating those risk factors to a more personalized form that fits into the current lifestyle of the individual in a meaningful way.
