Using public datasets to understand the psychological correlates of smoking, alcohol consumption, and obesity: A country-level analysis

In the present research, we investigate whether cultural value orientations (CVOs) and aggregate personality traits (Big-5) predict actual levels of alcohol consumption, smoking, and obesity across 50 countries using averages derived from millions of data points. Aggregate traits explained variance above and beyond CVOs in obesity (particularly neuroticism and extraversion), while CVOs explained variance beyond aggregate traits in alcohol consumption (particularly harmony and hierarchy). Smoking did not appear to be strongly linked to aggregated traits or CVOs. We conclude that an understanding of the cultural correlates of risky health behaviours may help inform important policies and interventions for meeting international sustainable development goals.
