Factors Affecting Nurses’ Health Promotion Behavior during the COVID-19 Pandemic Based on the Information–Motivation–Behavioral Skills Model

Background and Objectives: The COVID-19 pandemic has emerged as a major threat to nurses’ health. This study aimed to investigate the factors affecting nurses’ health promotion behaviors during the coronavirus disease 2019 (COVID-19) pandemic. Material and Methods: The participants were clinical nurses who had direct contact with patients at a university hospital in G province, Korea. Data were collected from March 16 to April 16, 2021, and the final analysis included data from 162 nurses. The general and lifestyle characteristics of the participants were analyzed using descriptive statistics, and the effect on health promotion behavior was analyzed using multiple regression with SPSS/WIN 21.0. Results: The results showed that the factors influencing nurses’ health promotion behavior during the COVID-19 pandemic were social support (β = 0.40, p < 0.001), self-efficacy (β = 0.27, p = 0.014), being married (β = 0.18, p = 0.018), having good health (β = 0.31, p < 0.001), and not skipping meals (β = 0.20, p = 0.001). The explanatory power of the variables was 51.4%. Therefore, health promotion programs to promote social support and self-efficacy are needed to improve nurses’ health promotion behaviors during the COVID-19 pandemic. Conclusions: These results indicate that the development of additional management strategies for health promotion among nurses during the COVID-19 pandemic is necessary. It is necessary to prepare organizational policies and manage self-care to improve nurses’ irregular eating habits during the ongoing pandemic.
