Skeletal age during hurricane impacts fluctuating asymmetry in Cayo Santiago rhesus macaques
Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023 Fluctuating asymmetry (FA), or random deviations from symmetry, can be used as a proxy for developmental instability, and anthropogenic and natural disruptions have been associated with increased levels of FA. In this study, we investigate the effect of demographic variables (age, sex, and decade of birth) and hurricane experience on FA in a model ...

Internalization of body shape ideals and body dissatisfaction: A systematic review and meta‐analysis
International Journal of Eating Disorders, Volume 54, Issue 9, Page 1575-1600, September 2021., 2021 Abstract Objective The present meta‐analysis summarizes existing evidence on the relationship between the internalization of body shape ideals (IBSI) and body dissatisfaction. Method Pooled effect sizes (r) were computed using a random‐effects model. The robustness of the results was examined using influence analyses.
