Loneliness: its correlates and associations with health risk behaviours among university students in 25 countries

The aim of this cross-national study was to assess factors associated with loneliness and to determine the degree to which loneliness affects health status and risk behaviours among university students Data were collected from 17 886 university students in 25 countries (females = 58 6%, from Africa = 33 5%) In multivariable logistic regression, loneliness was predicted by lower family wealth, living in a low or lower middle income country, and antecedent childhood Moreover, psychosocial factors of perceived lack of control, low organised religious activity, high non-organised religious activity, high intrinsic religiosity, and low social support were associated with loneliness Lonely students were also likely to self-report poor subjective health status, sleeping problems, short sleep duration, tobacco use, heavy internet use, aggressive behaviour, injury, and sexual risk behaviour University students with loneliness may be assisted by preventive health interventions aimed at enhancing their subjective well-being.
