Association between loneliness, physical activity, and participation in physical education among adolescents in...

Loneliness is an individual and social problem associated with an unhealthy lifestyle among adolescents. We examined the association between loneliness, physical activity, and participation in physical education lessons among school-going adolescents. Participants included 2517 adolescents aged 14-19 years selected from state public high schools in Amazonas, Brazil. Participants answered a questionnaire containing demographic information, physical activity, and participation in physical education lessons and loneliness. Our results showed that physically inactive adolescents and those who did not participate in physical education lessons were more likely to feel lonely. These findings underscore the need to target physically inactive adolescents and those non-engaged in physical education lessons when developing interventions to address loneliness.
