Race/Ethnicity Moderates Associations Between Childhood Weight Status and Early Substance Use
Identification of risk-factors for early drinking, smoking, and illicit drug use is essential for targeted substance abuse prevention. Few studies have examined associations between weight during childhood and early substance use, with mixed results. Some research has linked childhood obesity to higher rates of alcohol, cigarette, and/or cannabis use during adolescence, while others have found no associations. The present study examined the role of race/ethnicity as a potential moderator of relationships between childhood weight status and early use (by age 15) of alcohol, cigarettes, and cannabis.

The research shows that people actually anticipate smiles that are genuine but not smiles that are merely polite. The differing responses may reflect the unique social value of genuine smiles. “These findings give us the first clear suggestion that the basic processes that guide responses to reward also play a role in guiding social behavior on a moment-to-moment basis during interactions,” explains psychological scientist and lead researcher Erin Heerey of Bangor University (UK).
