Aging and Sexual Health: A Cross-Sectional Survey of Patients in a Canadian Urban Academic Family Health Team.

Primary care physicians are in a position to recognize sexuality as a core component of health. Data examining the sexual behaviours of Canadians over the age of 50 and the role of primary care in this domain is lacking. A cross-sectional survey was administered to patients over the age of 50, which assessed the importance of sexual activity, problems, and preferences in discussing sexual health with their primary care providers. A total of 39 per cent of patients indicated ongoing sexual activity and 52% of male participants reported current sexual activity compared with 25 per cent of females (p < 0.01). More males reported sexual activity as important than did females (69% vs. 45%, p < 0.01). Participants identifying sexual health concerns discussed physical dysfunctions more than emotional, social, or global health concerns (p < 0.01). More male participants discussed sexual health concerns with their family physician than did females (p < 0.01). The results of our study indicate that many individuals over the age of 50 continue to be sexually active, and that physical and non-physical concerns directly impact participation in sexual activity.

Genetic Similarities between Compulsive Overeating and Addiction Phenotypes: A Case for "Food Addiction"?

There exists a continuous spectrum of overeating, where at the extremes there are casual overindulgences and at the other a 'pathological' drive to consume palatable foods. It has been proposed that pathological eating behaviors may be the result of addictive appetitive behavior and loss of ability to regulate the consumption of highly processed foods containing refined carbohydrates, fats, salt, and caffeine. In this review, we highlight the genetic similarities underlying substance addiction phenotypes and overeating compulsions seen in individuals with binge eating disorder. We relate these similarities to findings from neuroimaging studies on reward processing and clinical diagnostic criteria based on addiction phenotypes. The abundance of similarities between compulsive overeating and substance addictions puts forth a case for a 'food addiction' phenotype as a valid, diagnosable disorder.
