RESUMO
BACKGROUND/PURPOSE: Exposure to sunlight has been shown to cause pigmentary alterations, photoaging and photocarcinogenesis. Understanding photoprotective patterns in adolescent populations is beneficial to public health initiatives. We utilized data provided by the American College Health Association's National College Health Assessment to evaluate photoprotective behaviors among adolescent populations. METHODS: Behavioral questions related to photoprotection were analyzed from the American College Health Association (ACHA) National College Health Assessment (NCHA) (Version III). RESULTS: When comparing races, Black/African American respondents had the lowest association of practicing photoprotective behaviors in comparison to white respondents (p < .05). When comparing US geographic regions, the south had the lowest association of photoprotective measures (p < .05). LIMITATIONS: The response rate of each institution varied, although there was still a large quantity of respondents. Finally, we cannot discern the specific reasoning for adolescent populations not using sunscreen. CONCLUSION: These data identify demographics where efforts to enhance education on photoprotective behaviors, specifically among skin of color and southern population, to support public health initiatives.

Interest in the pathology of Obsessive-Compulsive Disorder\has focused on brain network profiles of the dorsal Anterior Cingulate Cortex (dACC), given its role as a principal control region. Both motor control and working memory tasks induce dysfunctional dACC profiles in OCD. H H We contrasted dACC network profiles in OCD and age-comparable controls during both tasks (from data collected in the same participants). The motor task required participants to tap their right forefinger in response to a flashing white probe; the memory task was a standard n-back (2-Back) requiring participants to identify if a current stimulus was identical to the one presented two items before it in the sequence. Network interactions were modeled using Psychophysiological Interactions (PPI), a model of directional functional connectivity. Inter-group analyses indicated a) that the motor control task evoked greater dACC modulation than the working memory task, and b) that the modulatory effect was significantly greater in the OCD group. We also investigated the relationship between OCD symptom dimensions (lifetime obsession and lifetime compulsion measured using the CY-BOCS) and dACC network profiles in OCD. This analysis revealed a dichotomy between Obsessive-Compulsive symptom dimensions and the degree of dACC modulation: primarily increased obsessions predicted increased modulation during the motor control task, but primarily increased compulsions predicted increased modulation during the working memory task. These results re-emphasize the salience of the dACC in OCD, and the primacy of tasks of motor control in evoking dACC pathology in the disorder.
