Abstract
In recent years, there has been a heightened awareness around young adults and body image perception. The interaction between body image, physical activity level, and the use of technology has compelled the attention of today's researchers and medical professionals. However, the majority of literature focuses on an individual's Body Mass Index (BMI) rather than measures of body composition. The purpose of this study is to determine differences in an individual's body image perception and changes in physical activity level following a Dual Energy X-ray Absorptiometry (DEXA) assessment. A total of 40 healthy young adults, 18-30 years of age, will be sought to participate. Participants will complete a series of surveys throughout 6 weeks collecting data on demographics, body composition, physical activity, emotional state, and personal body image perception. A Garmin smartwatch will be fitted during the initial session and biometrics (I.e. steps, heart rate variability, minutes of physical activity, quality and hours of sleep) will be recorded for the duration of the 6-week study. Each participant will complete one DEXA assessment a week after the initial session. Descriptive statistics along with a Repeated-Measures ANOVA will be administered at a p< 0.05 to determine any significant differences in psychological and physical behavior. Post-hoc analysis will be administered, if applicable. Current literature suggests that receiving personalized body composition data may influence health-related behaviors and self-perception. It is anticipated that participants may increase their physical activity following the DEXA assessment, regardless of whether their results indicate a high or low body fat percentage. For individuals with initially low body image perception, unfavorable DEXA results may lead to greater body dissatisfaction. Conversely, those with more favorable results may experience improved body image and motivation for continued physical activity.
