"The main thrust of the subsequent research is that traditional masculinity—marked by stoicism, competitiveness, dominance and aggression—is, on the whole, harmful. Men socialized in this way are less likely to engage in healthy behaviors. For example, a 2011 study led by Kristen Springer, PhD, of Rutgers University, found that men with the strongest beliefs about masculinity were only half as likely as men with more moderate masculine beliefs to get preventive health care (Journal of Health and Social Behavior, Vol. 52, No. 2). And in 2007, researchers led by James Mahalik, PhD, of Boston College, found that the more men conformed to masculine norms, the more likely they were to consider as normal risky health behaviors such as heavy drinking, using tobacco and avoiding vegetables, and to engage in these risky behaviors themselves (Social Science and Medicine, Vol. 64, No. 11)."
