An examination of the relationship between height, height dissatisfaction, drive for thinness and muscularity, and eating disorder symptoms in north American women

Recent research has evidenced the importance of height dissatisfaction in male body image, however the impact of height on body image in women remains relatively unexplored. Our study aimed to investigate the association between height, heightdissatisfaction, body dissatisfaction, and eating disorder symptoms in a sample of 139 women from the USA. Participants were recruited using Amazon's MTurk and reported their actual and ideal height, as well as completing measures of height dissatisfaction, and drive for thinness, drive for muscularity, and eating disorder symptoms. A paired sample t-test was utilised to examine differences in participants' actual and ideal height. Additionally, linear hierarchical multiple regression was used to assess whether height, eating disorder symptoms, drive for thinness, and drive for muscularity uniquely predicted height dissatisfaction, and significant interactions were explored using a simple slope analysis complemented with a Johnson-Neyman analysis. Results showed that 48.92% of women reported identical actual and ideal height, 33.09% of women wanted to be taller, and 13.67% wanted to be shorter than their actual height. Additionally, shorter women tended to report greater height dissatisfaction, and higher levels of drive for thinness and drive for muscularity were associated with increased height dissatisfaction. However, eating disorder symptoms did not uniquely account for significant variance in height dissatisfaction once accounting for drive for thinness and muscularity. Our exploratory analysis also revealed that for taller than average women, height dissatisfaction was more strongly predicted by drive for muscularity, thus implicating the significance of height and muscle dissatisfaction for taller women. Overall, our study demonstrated that height and height dissatisfaction are important components to the theoretical construct of women's body image, and therefore should be integrated into theoretical models of female body dissatisfaction and considered in assessment, formulation, and treatment of body image-related disorders. Further research with larger and more diverse samples, including clinical populations, is warranted to validate and extend our findings.
