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.
