Background & Significance: Nearly a third of American adults have hypertension (HTN), which is projected to continue increasing. Healthy behaviors are necessary for HTN control, but are difficult or unfavorable to adopt. It is important to understand what influences the adoption or rejection of healthy behaviors to prevent serious future health outcomes. Time perspective (TP) is a thought process which can be categorized as general or specific to HTN. It may be associated with age, or a number of other factors. In addition to the Health Belief Model (HBM), it may provide a unique contribution to the adoption of healthy behavior.
Specific Aims: 1) Describe the association between general TP and HTN-specific TP in adults with HTN. 2) Explore the association of age with general TP and HTN-specific TP in adults with HTN, controlling for other demographic variables, personality differences and HTN knowledge. 3) Determine if TPs, when incorporated into the HBM, were related to selected current health behaviors in adults with HTN when controlling for other HBM variables.
Methodology: 99 adults with self-reported HTN, not caused by an underlying illness, completed an anonymous online survey. The survey collected demographics, personality traits, HTN knowledge, health behaviors related to HTN control, individual beliefs from the HBM (perceived susceptibility and severity; perceived benefits and barriers; self-efficacy; cues to action), and both general and HTN-specific TPs.
Results: General and HTN-specific TPs significantly correlated only in young adults. Age was significantly associated with present-fatalistic and future general TPs, and nonexperiential HTN-specific TPs. Adding TPs to the HBM significantly increased variance in four health behaviors: spiritual growth, interpersonal relations, medication adherence, and BMI. Individual beliefs from the HBM significantly increased the variance in overall health-promoting lifestyle, health responsibility, nutrition, spiritual growth, and stress management. Race significantly associated with six behaviors, controlling for TPs and HBM variables.
Conclusion: Age had subtle influence general and HTN-specific TPs. When incorporated into the HBM, TPs increased variance in a number of behaviors. However, race appeared to be a significant variable. More research is needed to better understand the relationship between TPs, race, and ultimately, adopting healthy behaviors to improve HTN control.
