Smoking leads to increased loneliness
Source: EurekAlert
What the research found
Study (observational). Presented at the European Respiratory Society Congress, an analysis of SHARE (over 50,000 people in 15 countries; mean age about 67) found current smokers scored lonelier on the UCLA scale than non-smokers and showed larger loneliness increases two years later, after demographics and baseline loneliness. About 22% smoked at baseline; 48.5% had more than two chronic illnesses. Association is not proof that quitting immediately reverses loneliness. Educational aging notes, not a smoking-cessation prescription.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
