We compare four different risk-taking propensity measures on their ability to describe and to predict actual risky behavior in the domain of health. The risk-taking propensity measures we compare are: (1) a general measure of risk-taking propensity derived from a one-item survey question (Dohmen et al., 2011), (2) a risk aversion index calculated from a set of incentivized monetary gambles (Hol...

Background: Drug abuse is one of the important variables influencing protective sexual behavior. The objective of this study was to explore how risky sexual behaviors develop in drug abusing women using human ecological theory.Methods: In this study, we used a descriptive exploratory approach. The participants were 32 drug abusing women from two of the selected drop-in centers (DICs) in south T...

OBJECTIVE To report the prevalence and comparison of cancer-linked health behaviors and identify risk factors associated with unhealthy behavior among adolescent siblings and cancer survivors. METHODS The Child Health and Illness Profile--Adolescent Edition (CHIP--AE) was completed by 307 survivors and 97 sibling controls 14-20 years of age. RESULTS Risky behavior ranged from 0.7% to 35.8% ...

African American (AA) adolescent girls are at heightened risk for HIV and sexually transmitted infections (STIs), and thus knowledge of factors related to risky sexual behavior in this population is crucial. Using Social Learning Theory (Bandura, 1977), this paper examines pathways from female caregivers' risky sexual behavior and substance use to adolescent girls' risky sexual behavior and sub...

background: physicians are one of the most important groups directly associated with public health and their health related lifestyle has a significant impact on their patient’s behaviors. several studies showed that the majority of medical students did not have appropriate and healthy behaviors. the aim of this study was to determine the prevalence of risky lifestyle knowledge and behaviors am...

Background. Young people constitute a large number of population worldwide, and majority of this population group lives in developing countries. They are at high risk of engaging in risky sexual behaviors. These risk sexual behaviors predispose youths to several sexual and reproductive health problems like STIs, HIV, unwanted pregnancy, and abortion. So, this study was conducted to assess the m...

Longstanding theory in behavioral ecology predicts that prey should evolve decreased foraging rates under high predation threat. However, an alternative perspective suggests that growth into a size refuge from gape-limited predation and the future benefits of large size can outweigh the initial survival costs of intense foraging. Here, I evaluate the relative contributions of selection from a g...
