  Background Insufficient sleep is commonly reported in adolescence and is negatively associated with a wide range of health outcomes. A way to grasp the complicated challenge of how sleep impact different aspects of the adolescents´ everyday life is by examining the relationship between sleep duration in schooldays and weekends on different health-related quality of life (HRQOL) subscales. Furthermore, to expand the understanding of possible underlying mechanisms between sleep and HRQOL, testing for self-efficacy as a possible mediator is of importance. Methods A cross-sectional study was performed among 696 adolescents aged 13–15 years from a schoolbased setting. All participants completed an electronic survey in their respective classrooms. The survey included demographic data, the School Sleep Habits Survey, the KIDSCREEN-27 questionnaire measuring HRQOL, and the General Perceived Self-Efficacy Scale. Statistical analyses were conducted using SPSS Statistics software including PROCESS macro by Andrew Hayes. Results Our findings revealed overall similar sleep patterns in boys and girls including longer sleep duration in the study sample during weekends (10:09 h) than in schooldays (08:36 h). Regression analyses revealed that sleep duration in schooldays was positively and statistically associated with HRQOL subscales psychological well-being (95% CI [0.44 to 1.33]), autonomy and parents (95% CI [0.12 to 1.06]), school environment (95% CI [0.47 to 1.40]), and self-efficacy (95% CI [0.01 to 0.47]). Sleep duration in weekends revealed no associations with the HRQOL subscales, except for the HRQOL subscale psychological well-being (95% CI [0.09 to 0.85]). Mediation analyses revealed that sleep duration in schooldays explained most of the associations (64 −75%) in 4 out 5 HRQOL subscales, except in the association with the HRQOL subscale physical well-being revealing an indirect effect of 71.9%. Conclusions This cross-sectional study described sleep among Norwegian adolescents and demonstrated that sleep durations in weekends and schooldays impact HRQOL and self-efficacy, revealing overall better outcome in HRQOL and self-efficacy with sufficient sleep during schooldays. These findings support the regularity of sleep and highlight the importance of sufficient sleep during schooldays, especially in a school-based sample of adolescents.

  Background: Increased knowledge about factors that can impact changes in adolescents’ health-related quality of life (HRQOL) is needed. The present study aimed to investigate possible HRQOL changes in adolescents at 14 and 16 years, and assess the impact of sociodemographic factors, gender, pain, self-esteem, self-efcacy, loneliness, and stress on HRQOL changes over time. Further, to assess HRQOL stratifed by gender. Methods: A longitudinal study involving 211 adolescents was conducted. Sociodemographic variables, pain, selfesteem, self-efcacy, loneliness, and stress were all assessed with well-validated instruments. KIDSCREEN-27 was used to measure HRQOL. Data were analyzed using independent t-tests, paired samples t-tests, and linear mixed models for repeated measures. Results: When all variables were added to the linear mixed models, stress, loneliness, and pain were signifcantly, independently associated with a reduction in HRQOL change scores for four of the fve KIDSCREEN subscales. Time was signifcantly associated with a reduction in physical and psychological well-being. Self-efcacy and self-esteem were signifcantly associated with an increase in HRQOL change scores for four and two subscales, respectively. Male gender was signifcantly negatively associated with changes in social support and peers compared to female gender. Conclusion: Our results demonstrated a signifcant decline in adolescents’ HRQOL regarding physical and psychological well-being for the age range 14–16 years. Furthermore, we found that stress, loneliness, and pain have a signifcant negative impact on HRQOL changes, whereas self-esteem and self-efcacy have a signifcant positive impact. Our results highlight the importance of increased understanding regarding factors associated with changes in adolescents’ HRQOL to enable accurate and strategic interventions.

  Background: For many adults, their role as a parent is a vital part of their lives. This role is likely to be associated with a parent’s health-related quality of life (HRQOL). The aim of this study was to explore the associations between gender, demographic and psychosocial variables, pain, and HRQOL in parents of 14–15-year-old adolescents. Methods: This was a cross-sectional study that included 561 parents. Data on demographic, psychosocial variables and pain were collected using validated instruments. HRQOL was assessed using the RAND-36. Data were analysed using univariate and hierarchical multiple linear regression analyses. Results: Four hundred and thirty-six (78%) mothers and 125 (22%) fathers with a mean age of 45 (SD=5) years were included. Eighty-one per cent were married/cohabiting, 74% worked full time, and 50% had university education of more than 4 years. Almost one-third reported daily or weekly pain, and more than half (58%) reported using pain analgesics during the previous 4 weeks. Mothers reported signifcantly lower scores on self-efcacy, self-esteem and for all RAND-36 domains, including the physical component summary (PCS) and mental component summary (MCS) and experienced greater stress than fathers. Hierarchical regression analyses showed that working part-time (beta=0.40) or full time (beta=0.52) (reference: not working) had the strongest positive efect on PCS. Absence from work for >10 days (beta=−0.24) (reference: no absence), short-term pain (beta=−0.14), chronic pain (beta=−0.37) (reference: no pain), and stress (beta=−0.10) had the strongest negative efects on PCS. High self-esteem (beta=0.11) had the strongest positive efect, whereas stress (beta=−0.58) and absence from work for>10 days (beta=−0.11) (reference: no absence) had the strongest negative efects on MCS. Conclusion: Mothers reported signifcantly lower scores on self-efcacy, self-esteem, and HRQOL, and experienced greater stress than the fathers. A high proportion of parents reported pain. Pain, stress, and low work afliation were strongly associated with decreased HRQOL in parents. We recommend that parents of adolescents should be provided guidance about coping with pain and stress, and facilitation of a strong work afliation because these seem to be important to parents’ HRQOL.

  BACKGROUND: Lifestyle interventions seem promising with regard to cancer patients' potential for physical and psychological health benefits and as an empowerment tool. Nevertheless, there is a lack of knowledge concerning cancer patients' longer-term experiences of participating in comprehensive lifestyle interventions. OBJECTIVE: The aim of this study was to explore cancer patients' long-term experiences of participating in a 12-month individualized comprehensive lifestyle intervention study focusing on physical activity, diet, smoking cessation, and stress management while receiving curative or palliative chemotherapy. METHODS: A qualitative design with semistructured interviews of 7 curative and 7 palliative cancer patients was conducted 12 months after inclusion in lifestyle intervention. Data were analyzed following a phenomenological-hermeneutic approach. RESULTS: Two main themes emerged: (1) awareness of the importance of a healthy lifestyle during cancer treatment and (2) individual follow-up; it's good to have someone to talk to. CONCLUSIONS: Participation in a 12-month comprehensive lifestyle intervention is both feasible and desirable in curative and palliative patients. However, although the curative participants' motivation and perceived ability to adhere to lifestyle recommendations increased during the intervention period, the palliative participants' perceived ability to adhere decreased even though they were overall highly motivated. IMPLICATIONS FOR PRACTICE: Our findings encourage the future implementation of lifestyle interventions during cancer treatment, even in cancer patients with advanced disease. However, when implementing lifestyle interventions, healthcare professionals must keep the patients' motivation, perceived ability to adhere to lifestyle recommendations, and individual needs in mind.
