Physical "lying flat": The negative effect of personal relative deprivation on health-promoting lifestyles.

ABSTRACT

BACKGROUND: Social comparison is an inevitable aspect of human life, often leading to personal relative deprivation, wherein individuals experience a sense of unfair treatment when they perceive themselves as being at a disadvantage in comparison to others. Earlier research has observed a phenomenon called "lying flat" associated with personal relative deprivation, characterized by a lack of motivation for self-improvement. The purpose of this study is to investigate whether this pattern is suitable for the domains of health-promoting lifestyles given that health-promoting is driven by self-improvement motivation. METHODS: In three studies conducted in China, an understudied non-Western society, we investigated the association between personal relative deprivation and health-promoting lifestyles by utilizing diverse measures and samples. RESULTS: Findings from Study 1 (N = 12,465) indicated a negative relationship between personal relative deprivation and health-promoting behavior. This effect was particularly prominent among older individuals (Study 2, N = 11,378). Study 3 (N = 234) indirectly explored the possibility that a decreased priority given to health goals explains the reduced adoption of health-promoting behaviors when experiencing personal relative deprivation. LIMITATIONS: First, all health-promoting lifestyles are self-reported. Second, the mechanism between PRD and health-promoting lifestyles was not directly examined. CONCLUSION: Overall, this research confirms the physical "lying flat" phenomenon, highlighting that personal relative deprivation contributes to unhealthy diets and physical inactivity. Moreover, our findings also suggest that the lower significance placed on health goals relative to other life goals may serve as an underlying reason for this phenomenon.
