How the Exposure to Beauty Ideals on Social Networking Sites Influences Body Image: A Systematic Review of Experimental Studies

Sharing and viewing photos on social networking sites (SNSs) have been identified as particularly problematic for body image. Although correlational research to date has established that SNS use is associated with increased body dissatisfaction, only experimental studies can enhance confidence in the conclusions drawn. For this reason, this systematic review synthesizes data from 43 experimental studies (N = 8637; %F = 89.56; mean age = 21.58 ± 1.78) examining the effect of viewing idealized images (i.e., attractive, thin, and fit) and body positive content on SNSs on body image. Two studies were conducted on adolescents. Each study had slight variations in how the images were presented for each category (e.g., selfies and photos taken by others). The wide variability in experimental stimuli and psychological moderators used in the published research make a systematic review more feasible and meaningful than a meta-analysis. Findings indicate that viewing idealized images on SNSs lead to increased body dissatisfaction among young women and men. State appearance comparison (i.e., engaging in social comparison while viewing images) significantly mediated the effect, whereas trait appearance comparison (i.e., the relatively stable general tendency to engage in social comparison) was a significant moderator. Mixed results were found regarding the exposure to body positive images/captions. Viewing images on SNSs depicting unattainable beauty ideals leads young people to feel dissatisfied about their bodies, with appearance comparison processing playing an important role. More research is required to assess the long-term effects.

Body Image Problems in Individuals with Type 1 Diabetes: A Review of the Literature

Despite type 1 diabetes' (T1D) potential influence on adolescents' physical development, the occurrence of body image problems of adolescents with diabetes remains unclear. No research synthesis has yet addressed this issue. This study aims to systematically evaluate the empirical evidence concerning body image in individuals with T1D in order to provide an overview of the existing literature. Using PRISMA methodology, 51 relevant studies that fulfilled the eligibility criteria were found, the majority of them (N = 48) involving youth. The findings varied across studies: 17 studies indicated that in youth with T1D, body dissatisfaction was common and that body concerns were generally greater in youth with T1D than in controls; nine studies did not find any differences in body image problems between participants with and without T1D; three studies described higher body satisfaction in youth with diabetes than in controls; and three studies reported mixed results. Body concerns in individuals with T1D were often found to be associated with negative medical and psychological functioning. The variability and limits in assessment tools across studies, the overrepresentation of female subjects, and the fact that most research in this field is based on cross-sectional data are stressed in the interpretation of these mixed findings. Future research directions that could improve the understanding of body image concerns and clinical implications are discussed.
