Factors Associated With Health-promoting Behaviors Among Nurses in South Korea: Systematic Review and Meta-analysis Based on Pender's Health Promotion Model

Abstract

Purpose: Although the importance of health promotion for nurses is increasing, there is a lack of meta-analyses targeting nurses in the world. This study aimed to identify the effect sizes between the health-promoting behaviors and related variables of nurses working in Korea. Methods: Systematic review and meta-analysis were conducted according to the PRISMA and MOOSE guidelines. The literature included in this meta-analysis was published between 1994 and 2022 in core databases such as KMbase, KISS, KoreaMed, ScienceON, DBpia, NAL, RISS, CINAHL, CENTRAL, WoS, PubMed, and hand searched. In this study, the PICO-SD framework was applied with Participants being nurses actively working in various healthcare settings across Korea, and for a more comprehensive search, intervention and comparisons were not set. The outcomes measured were nurses' health-promoting behaviors, assessed using structured tools. The study design included observational studies. The Comprehensive Meta-Analysis and the R software program were used for meta-analysis. Results: In total, 50 articles were selected for the systematic review and meta-analysis. The total effect size of the 50 articles was moderate (correlation effect size [ESr] = 0.30). The individual variables presented in the 50 articles were classified into nine sub-categories according to Pender's Health Promotion Model (HPM). Among them, situational influences demonstrated the largest effect size (ESr = 0.44, number of studies [k] = 2), followed by perceived self-efficacy (ESr = 0.39, k = 10) and activity-related affect (ESr = 0.32, k = 12). Conclusions: To achieve the optimal health status of nurses through health promotion intervention programs, these effective variables – situational influences, perceived self-efficacy, and activity-related affect – should be considered when developing the intervention program for nurses.
