Dust Phenomenon: Threat Appraisal of Cardiovascular Patients

Abstract

Introduction: Dust phenomenon is a major environmental problem in world that threatens the middle-east countries specifically. In order to develop a need-based policy and regulate the supporting health program to reduce dust effects requires a proper understanding of the public beliefs about threats posed by this issue. The purpose of this study was to explain the threat appraisal patients with cardiovascular diseases regarding exposure to dust phenomena.

Method: This qualitative content-analysis study was conducted from January to June 2018. The participants included 28 cardiovascular patients who referred to the healthcare centers in Ahvaz City. Semi-structured interviews were conducted with open-ended questions and inspiration from threat appraisal process constructs were used to collect data. All data were gathered, transcribed, and analyzed using MAXQDA-10 software and in-depth analysis.

Findings: Perceived threat constructs were used and 4 categories and 9 sub-categories were extracted: perceived likelihood of exposure to dust (perceived likelihood of increased non-respiratory problems, perceived likelihood of increased respiratory problems), belief in seriousness and danger of exposure to dust (understanding the severity of physical complications, understanding the severity of mental and psychological complications, understanding the severity of economic complications), external reward of exposure to dust (improving personal and social relationships, improving financial problems), internal reward of exposure to dust (pleasant feeling).

Conclusion: This study provided a clearer and deeper understanding of the threat posed by exposure to dust among cardiovascular patients. Based on the results, the authorities can design more targeted and more effective protective plans to raise awareness among community members, especially cardiovascular patients about the negative effects of exposure to dust and the ways to reduce its exposure.
