Adolescents' self perceived acne-related beliefs: from myth to science.

BACKGROUND: Acne vulgaris is recognized as the third most prevalent skin disease worldwide, with highest prevalence among adolescents. Beliefs and perceptions of adolescents about acne are incoherent in the literature. OBJECTIVES: To assess the most frequently reported acne-related beliefs in adolescents in order to focus on misconceptions and develop proper recommendations. METHODS: A cross-sectional community-based study on representative sample of 2516 schoolchildren was conducted in six randomly selected secondary schools in Belgrade, Serbia. Only schoolchildren with present or past acne history participated. Factors believed to aggravate or ameliorate acne were recorded and analyzed, and the comparisons between girls and boys were evaluated using Pearson's chi-squared test. RESULTS: A total of 1452 schoolchildren with acne participated, aged 14-18 years, among them 801 (55.2%) girls and 651 (44.8%) boys. Boys significantly more frequently believed that sweating, exercise, and dairy foods aggravate acne, whereas girls significantly more frequently blamed emotional stress, sweets, fatty foods, sun, and lack of sleep. The top four amelioration factors were as follows: comedone extraction, healthy diet, sun exposure, and increased water consumption. Acne regression was more frequently perceived to be linked with cigarettes in boys, but with sun exposure and weight loss in girls. STUDY LIMITATIONS: The narrow age span of adolescents (14-18 years) and exclusion of acne-free adolescents are limitations due to study design. CONCLUSION: This survey is part of the first epidemiological study on a representative sample in the Western Balkan region. The significance of the most frequent acne-related beliefs is discussed and myths about acne are highlighted.

Visceral Adiposity Index is not Superior over Anthropometric Parameters with regards to Inflammation in Healthy Adolescent Girls.

OBJECTIVE: Better than simple anthropometric parameters, the visceral adiposity index (VAI) has recently been proposed as a predictor of cardiometabolic risk in adults. However, there are conflicting results on the associations of these parameters in children and adolescents. Therefore, we aimed to estimate this potential relationship between VAI, anthropometric parameters (i.e., body mass index [BMI], waist circumference [WC], and waist-to-height ratio [WHtR], respectively), and inflammation as measured by high-sensitivity C-reactive protein (hs-CRP) levels in a cohort of adolescent girls. METHODS: A total of 90 adolescent girls from 16 to 19 years old were included in cross-sectional study. Anthropometric and biochemical parameters (glucose, lipid parameters, and hsCRP) were measured. The VAI, derived from anthropometric and lipid parameters, calculated {[WC/36.58 + (1.89 × BMI)] × (triglycerides/0.81) × (1.52/HDL-cholesterol)} was calculated. RESULTS: A comparison of the receiver operating characteristic (ROC) curves showed that all the curves for the anthropometric parameters (e.g., BMI, WC, WHtR) had excellent discriminatory capability with regard to inflammation level status (low vs. high level) and significantly larger areas under the curve (AUC = 0.885, AUC = 0.863, AUC = 0.860, respectively; P < 0.001) than the ROC curve for VAI did (AUC = 0.686; P = 0.021). CONCLUSION: Visceral adiposity index is not superior over anthropometric parameters in relation to inflammation as measured by high sensitivity C-reactive protein in adolescent girls.
