Does negative affectivity have an association with achieving target values in hypertensive patients: primary care perspective

Abstract

Objectives: The current study aimed to seek the relationship between demographic characteristics, treatment compliance status, and type D personality characteristics to achieve target BP values.

Methods: This cross-sectional research was conducted on HT patients at three family medicine health-care services in Ankara, Turkey, between 1 February 2021, and 31 January 2022. The sociodemographic questionnaire survey, Hill-Bone Compliance to High Blood Pressure Therapy Scale (HBCHBPTS), and Type D Scale-14 (DS-14) were applied to 317 patients. HBCHBPTS consists of 14 items with three domains. DS-14 consists of 14 items assessing negative affectivity (NA) and social inhibition (SI).

Results: Patients with NA were less likely to achieve the SBP target values (62.20% vs 47.50, p = 0.011). NA scores were correlated with HBCHBPTS total scores and HBCHBPTS medication-taking domain scores. Living in a city center (β = -0.157, p = 0.017), not smoking (β = -0.114, p = 0.042), knowing the names of HT drugs (β = - 0.152, p = 0.005), having a Mediterranean-style diet (β = -0.182, p = 0.002), starting treatment immediately after diagnosis (β = -0.121, p = 0.029), older age (β = -0.164, p = 0.028), having less NA scores (β = 0.171, p = 0.029) were effective on better treatment adherence. Variables affecting the failure to achieve the SBP target values were not being in the extended family (p = 0.022, OR: 0.337), anti-HT drug side effects (p = 0.029, OR: 2.566), higher HBCHBPTS total scores (p = 0.001, OR: 1.178), higher DBP values (p < 0.001, OR: 1.141).

Conclusion: HBCHBPTS total and HBCHBPTS medication-taking domain indicators worsened as the NA and SI characteristics increased. Predictors, including those not living in an extended family, being affected by the side effects of anti-HT drugs, high HBCHBPTS total score, and high DBP values, were effective in failure to achieve the SBP target values.
