ABCs or Attack-Boom-Crash? A longitudinal analysis of associations between media content and the development of problematic media use in early childhood.

Researchers have begun to extensively examine pathological (or addictive-like) media use during adolescence and adulthood. However, few studies have examined precursors to these types of behavior (termed problematic media use) in early childhood, with even fewer examining predictors of this behavior over time. The current longitudinal study examined bi-directional associations between television content (educational, prosocial, and violence) and problematic media use over a 1-year period during early childhood.

Association between coarse particulate matter and inflammatory and hemostatic markers in a cohort of midlife women.

Background: Exposure to particulate matter air pollution has been associated with cardiovascular disease (CVD) morbidity and mortality; however, most studies have focused on fine particulate matter (PM) exposure and CVD. Coarse particulate matter (PM) exposure has not been extensively studied, particularly for long-term exposure, and the biological mechanisms remain uncertain.

Methods: We examined the association between ambient concentrations of PM and inflammatory and hemostatic makers that have been linked to CVD.

Contributions of Mainstream Sexual Media Exposure to Sexual Attitudes, Perceived Peer Norms, and Sexual Behavior: A Meta-Analysis.

Purpose: Decades of research have examined the impact of exposure to nonexplicit portrayals of sexual content in media. There is only one meta-analysis on this topic, which suggests that exposure to "sexy media" has little to no effect on sexual behavior. There are a number of limitations to the existing meta-analysis, and the purpose of this updated meta-analysis was to examine associations between exposure to sexual media and users' attitudes and sexual behavior.

A meta-analysis of prosocial media on prosocial behavior, aggression, and empathic concern: A multidimensional approach.

Studies examining the effects of exposure to prosocial media on positive outcomes are increasing in number and strength. However, existing meta-analyses use a broad definition of prosocial media that does not recognize the multidimensionality of prosocial behavior. The aim of the current study is to conduct a meta-analysis on the effects of exposure to prosocial media on prosocial behavior, aggression, and empathic concern while examining multiple moderators that the prosocial behavior literature suggests are important to our understanding of why individuals voluntarily help others (e.

The Effect of Media on Body Image in Pregnant and Postpartum Women.

Much research has found that exposure to certain types of media portrayals of women can be related to body image concerns among women. The current paper focuses on the impact of certain messages on pregnant and postpartum women. These women are rarely examined in a media research context but are particularly vulnerable to body image concerns.
