The impact of seeing and posting photos on mental health and body satisfaction:A panel study among Dutch and Japanese adolescents

A vivid scholarly debate addresses the extent to which social media usage is detrimental for adolescents’ mental health and body satisfaction. The current study aims to advance the debate in three ways: (1) we differentiate between different types of active and passive social media use (i.e., authentic vs. edited content), (2) we examine both between- and within-person results, and (3) we take a cross-national approach. Therefore, a three-wave panel study was conducted among 987 adolescents in Japan (N = 433) and the Netherlands (N = 554) to longitudinally investigate the relationships between active visual self-presentation, passive exposures thereto, and mental health and body satisfaction. Between-person results generally indicate that, regardless of being active or passive, both creating or seeing authentic content can be associated with increases in mental health and body satisfaction. Contrary, both creating and seeing edited content can coincide with reduced levels of mental health and body satisfaction. Nevertheless, the results should be seen in light of differences in between- and (lagged) within-person processes as well as cross-country differences. In all, evidence exemplifies the need for a communication-centered approach specifying content heterogeneity, showcases differences in between- and within-person effects, and demonstrates cross-national differential susceptibly to media effects

Me, my selfie, and I:the relations between selfie behaviors, body image, self-objectification, and self-esteem in young women

Due to the enormous popularity of social networking sites (SNSs), online and offline social lives seem inextricably linked, which raises concerns for how SNS use relates to psychological health. Similarly, the omnipresence of selfies on SNSs—a form of appearance-related exposure—raises concerns regarding psychological health. This study aimed to investigate the relationships between body image, self-objectification, self-esteem, and various selfie behaviors among young women (N = 179). We hypothesized that a worsened body image (i.e., higher body dissatisfaction or lower body appreciation), higher levels of self-objectification, and lower self-esteem would precede greater engagement in selfie behaviors. Structural equation modeling showed that body appreciation is associated with greater engagement in selfie selection and deliberate posting, and that self-objectification is related to greater engagement in all selfie behaviors assessed. In support of our proposed model, a reversed model was also tested that showed poorer results. These findings suggest that body image may serve not only as an outcome of SNS use but also as a motive preceding selfie behaviors

Non-AIDS defining cancers in the D:A:D Study-time trends and predictors of survival : a cohort study

BACKGROUND:Non-AIDS defining cancers (NADC) are an important cause of morbidity and mortality in HIV-positive individuals. Using data from a large international cohort of HIV-positive individuals, we described the incidence of NADC from 2004-2010, and described subsequent mortality and predictors of these.METHODS:Individuals were followed from 1st January 2004/enrolment in study, until the earliest of a new NADC, 1st February 2010, death or six months after the patient's last visit. Incidence rates were estimated for each year of follow-up, overall and stratified by gender, age and mode of HIV acquisition. Cumulative risk of mortality following NADC diagnosis was summarised using Kaplan-Meier methods, with follow-up for these analyses from the date of NADC diagnosis until the patient's death, 1st February 2010 or 6 months after the patient's last visit. Factors associated with mortality following NADC diagnosis were identified using multivariable Cox proportional hazards regression.RESULTS:Over 176,775 person-years (PY), 880 (2.1%) patients developed a new NADC (incidence: 4.98/1000PY [95% confidence interval 4.65, 5.31]). Over a third of these patients (327, 37.2%) had died by 1st February 2010. Time trends for lung cancer, anal cancer and Hodgkin's lymphoma were broadly consistent. Kaplan-Meier cumulative mortality estimates at 1, 3 and 5 years after NADC diagnosis were 28.2% [95% CI 25.1-31.2], 42.0% [38.2-45.8] and 47.3% [42.4-52.2], respectively. Significant predictors of poorer survival after diagnosis of NADC were lung cancer (compared to other cancer types), male gender, non-white ethnicity, and smoking status. Later year of diagnosis and higher CD4 count at NADC diagnosis were associated with improved survival. The incidence of NADC remained stable over the period 2004-2010 in this large observational cohort.CONCLUSIONS:The prognosis after diagnosis of NADC, in particular lung cancer and disseminated cancer, is poor but has improved somewhat over time. Modifiable risk factors, such as smoking and low CD4 counts, were associated with mortality following a diagnosis of NADC
