The role of perceived loneliness and sociodemographic factors in association with subjective mental and physical health and well-being in Norwegian adolescents.

AIMS Adolescence is a particularly salient period for understanding the role of perceived loneliness for subjective health and well-being. This study investigated sociodemographic differences (sex, age, self-reported socio-economic status (SES)) in loneliness and associations between sociodemographic factors, loneliness and self-rated health (SRH), subjective health symptoms, symptoms of depression/anxiety and mental well-being (MWB) in a sample of Norwegian adolescents. METHODS The study was based on a cross-sectional sample of 1816 adolescents aged 15-21 years. The participants reported scores on an 11-item scale assessing subjective health complaints (SHC), one item each assessing SRH and loneliness, the 10-item version of the Hopkins Symptom Checklist and the seven-item version of the Warwick-Edinburgh Mental Well-Being Scale. SES was assessed using perceived family economy and parents' education. Data were analysed with descriptive, comparative and multiple linear regression analyses. RESULTS The multivariate results showed that boys scored significantly higher on MWB than girls did, whereas girls scored significantly higher on loneliness, depression/anxiety and SHC. Perceptions of poorer family finances were significantly associated with higher levels of SHC and depression/anxiety, lower levels of MWB and more negative SRH. Loneliness showed significant positive associations with depression/anxiety and SHC, and significant negative associations with MWB and SRH. A significant moderation effect of sex by loneliness was found in association with depression/anxiety, with stronger associations for girls. CONCLUSIONS The findings in this study support the significant roles of sex, perceptions of family finances and loneliness in association with adolescent's subjective mental and physical health and well-being, especially mental health.
