ABSTRACT
Background
Understanding the relationship between the perceived body weight, body mass index (BMI), and weight management-related behaviors is critical to preventing obesity in young adults.
Purpose
To explore the relationship between perceived body weight and weight management-related behaviors and to assess the mediating effects of BMI between perceived body weight and weight management-related behaviors among young adults.
Methods
Using data (n = 4882) from the National Longitudinal Study of Adolescent to Adult Health, multiple linear regression and a series of mediation analyses were applied to analyze the data.
Results
Both perceived body weight and BMI were significantly associated with breakfast consumption and sleep for overall participants (p < .001; p < .001). Perceived body weight and BMI were significantly associated with breakfast consumption among young female adults (p < .001). Perceived body weight and BMI were significantly associated with sleep among young male adults (p = .03). BMI is found to mediate the relationship between perceived body weight and breakfast consumption.
Discussion
The study demonstrated both perceived body weight and BMI contribute to certain weight management-related behaviors. BMI could be the inflammatory mechanism of health behavior change.
Translation to Health Education Practice
Development of tailored interventions or culturally appropriate weight management educational programs are needed for young adults. Findings of this study could have implications for public health education.
