Exploration of Body Self-Image and Associated Body Composition Supplement Behaviors in College Students.

Higher scores on the Investment in Ideals and Health-Fitness Evaluation subscales were significantly associated with higher performance-enhancing supplement (PES) use.

• Chi-square analyses examined supplement prevalence in students ranked within the highest and lowest tertiles of each subscale
• Both the Investment in Ideals subscale and the Health-Fitness Evaluation subscale showed significantly higher PES use in the high-scoring group compared to the low-scoring group
• Both subscales and male gender were identified as significant predictors of PES use in logistic regression analysis
• Sample consisted of college students aged 18-28 years (N = 122)

Higher scores on the Fatness Evaluation, Negative Affect, and Social Dependence subscales were significantly associated with higher weight-loss supplement (WLS) use.

• Chi-square analyses found significantly higher WLS use among students scoring in the highest tertile for Fatness Evaluation, Negative Affect, and Social Dependence subscales compared to the lowest tertile
• Fatness Evaluation subscale and age were identified as significant predictors of WLS use in logistic regression analysis
• Middle tertile data were excluded as part of the extreme-group design for chi-square analyses
• All responses were included in the logistic regression analysis

Body self-image subscales were not significantly associated with general dietary supplement (DS) use.

• None of the nine psychological subscales showed significant associations with general dietary supplement use in either chi-square or logistic regression analyses
• General dietary supplement use was assessed via a single dichotomous question
• This finding contrasts with the significant associations found for PES and WLS use
• The Body Self-Image Questionnaire-Short Form assessed nine psychological subscale groups

Male gender was a significant predictor of performance-enhancing supplement use in logistic regression analysis.

• Male gender was identified alongside the Investment in Ideals and Health-Fitness Evaluation subscales as a significant predictor of PES use
• Three dichotomous questions assessed general dietary (DS), performance-enhancing (PES), and weight-loss (WLS) supplement use
• The sample included college students aged 18-28 years (N = 122)

Age was a significant predictor of weight-loss supplement use in logistic regression analysis.

• Age was identified alongside the Fatness Evaluation subscale as a significant predictor of WLS use in logistic regression
• The study sample ranged from 18 to 28 years of age
• WLS use was assessed via a single dichotomous question

The study used an extreme-group design with an established body image instrument to examine supplement behaviors in a college student sample.

• Participants (N = 122; aged 18-28 years) completed the Body Self-Image Questionnaire-Short Form (BSIQ-SF) to assess body self-image across nine psychological subscale groups
• Student scores were ranked as high, moderate, or low percentile within the study sample
• Chi-square analyses compared supplement prevalence between the highest and lowest tertiles, excluding the middle tertile
• Logistic regression analysis included all responses and examined predictors of each supplement type
