In the study, 218 adolescents responded to measures of perfectionistic self-presentation (i.e., perfectionistic self-promotion, nondisplay of imperfection and nondisclosure of imperfection), pain intensity, pain catastrophizing, pain interference, and fatigue. Four hierarchical regression analyses and three mediation analyses were conducted. Our results showed that perfectionistic self-promotion was significantly and independently associated with pain intensity and that nondisplay of imperfection was significantly and independently associated with pain catastrophizing, pain interference, and fatigue. Nondisclosure of imperfection was not significantly associated with any criterion variable. Pain catastrophizing mediated the association between both perfectionistic self-presentation and nondisplay imperfection and pain interference but not between nondisclosure of imperfection and pain interference. The findings provide new information about the role of perfectionistic self-presentation in children and adolescents' experience of pain. These findings, if replicated, support perfectionism as a potential target of pain treatment in young people.Polyphenols (PPs) are the naturally occurring bioactive components in fruits and vegetables, and they are the most abundant antioxidant in the human diet. Studies are suggesting that ingestion of PPs might be helpful to ameliorate metabolic syndromes that may contribute in the prevention of several chronic disorders like diabetes, obesity, hypertension, and colon cancer. PPs have structural diversity which impacts their bioavailability as they accumulate in the large intestine and are extensively metabolized through gut microbiota (GM). Intestinal microbiota tra
