Quality Appraisal of Quality of Life Research in Children and Adolescents with Food Allergy: A Systematic Review.

INTRODUCTION: Quality of life (QOL) and health-related quality of life (HRQOL) in children and adolescents with food allergies have been an important and steadily growing field of research for the past 20 years. There seem to be conceptual and methodological challenges that might influence the face validity of QOL and HRQOL research in general health research, but this has not been investigated in pediatric and adolescent food allergy research up until now. The aim of this study was to perform a systematic review of the QOL and HRQOL studies on food allergy in children and adolescents under the age of 18. METHODS: The systematic review was conducted on studies purporting to measure QOL or HRQOL in children and adolescents with food allergies. The literature search was developed in Ovid MEDLINE and databases used in the review were Embase, Cochrane Database of Systematic Reviews, CINAHL, and Scopus. Studies were evaluated based on a set of face validity criteria developed by Gill and Feinstein in 1994 and refined by Moons et al. in 2004. RESULTS: Out of 61 studies eligible for the review, 11 (18%) defined QOL or HRQOL and two distinguished QOL from HRQOL. The Food Allergy Quality of Life (FAQLQ) instrument series is the most frequently used HRQOL measurement among the studies included. QOL and HRQOL were employed interchangeably in half of the studies, some of them also using a third term in addition. CONCLUSION: Our findings lead to the conclusion that the research field investigated contains methodological and conceptual shortcomings regarding QOL and HRQOL. An increased awareness toward the terminology as well as consideration of points to reflect upon will be beneficial, as this will also improve the validity of future studies.

The relationship between gender, psychosocial factors, pain, health literacy and health-related quality of life in parents of Norwegian adolescents one year into the COVID-19 pandemic.

BACKGROUND: Stress impacts healthy behaviours and may influence life and health-related quality of life (HRQOL). A stressful event occurred when the COVID-19 pandemic hit in March 2020. The present study aims to explore possible gender differences in stress, psychosocial factors (self-efficacy, self-esteem, loneliness), pain, HL, and HRQOL in parents of adolescents one year into the COVID-19 pandemic, and to explore possible associations between gender, demographic and psychosocial factors, pain, HL, and HRQOL. METHODS: Parents of adolescents aged 16-17 took part in the study from January to February 2021, when the COVID-19 pandemic was ongoing. Data on socio-demographics, stress, self-efficacy, self-esteem, pain, HL, loneliness, and HRQOL were collected. HRQOL was assessed using RAND-36. RESULTS: Among the 320 parents from the general population, the mean age was 47.6 (standard deviation (SD) = 4.6) years, 81% were mothers, 79% were married or cohabiting, 81% had a university degree, and the majority worked full time (78%) or part time (13%). The average pain score was low, 0.48 (95% CI [0.43-0.54]). However, 50% of the parents reported persistent pain and more mothers reported persistent pain compared to fathers (53% vs. 37%). The parents' mean (SD) score for RAND-36 was 52.1 (95% CI [51.2-53.0]) for the physical component summary (PCS) score and 51.0 (95% CI [50.0-52.1]) for the mental component summary (MCS) score. Mothers reported significantly lower scores for all the eight RAND-36 domains and the PCS and MCS scores. Adjusting for gender, age, living condition, education, pain, HL, self-efficacy and loneliness, we revealed no associations between stress and RAND-36-PCS. University education of four years or more was positively associated (B = 3.29, 95% CI: [0.78-5.80]) with RAND-36-PCS, while persistent pain was negatively associated (B = -7.13, CI: [-9.20- -5.06]). We identified a strong negative association between RAND-36-MCS and stress (B = -43.11, CI: [-48.83- -37.38]) and a positive association with older age (B = 0.21, CI: [ 0.04, 0.39)]. CONCLUSION: One year into the COVID-19 pandemic, we identified a strong negative association between stress and mental HRQOL, while pain was strongly negatively associated with physical HRQOL.

The effect of the association between food budget and food quality on adherence to national guidelines in kindergartens, and the impact of budget limit on the food quality.

Background: In Norway, almost 97% of children attend kindergartens. Most of the daily food intake happens during the day in kindergartens, and the quality of food and meals being served is essential to promote healthy food habits. There is variation in the food that kindergartens provide, and kindergartens can ask for additional payment from parents to cover the food. There are no rules neither across kindergartens for the food offering nor how much additional payment kindergarten can request. Objective: Our main objective is to investigate possible associations between the food budget and the quality of food offered in kindergartens. We specifically aimed to identify budget levels that were associated with better adherence to national guidelines, thereby the quality of the food provided, as recommended by the Norwegian Directorate of Health. Design: A cross-sectional study design, based on kindergarten pedagogical leaders' answers to a web-based questionnaire. Settings: Private and public kindergartens across Norway are included in this present study. Participants: A total of 324 kindergarten staff attending on behalf of kindergartens participated. Results: The food budget thresholds over NOK 199 are associated with higher quality of served food, in adherence to national guidelines of food and meals (odds ratio 5.2, CI = [1.5, 16.5]), compared to thresholds under 199 NOK. However, increasing the monthly food budget per child to low (200-299 NOK), medium (300-399 NOK), high (400-499 NOK), or very high (>500 NOK) levels did not lead to an improvement in food quality. Conclusion: The main results reveal that budget plays a limited role in the quality of food and meals served as long as it is above 'very low' (199 NOK) food budget threshold. We assume that other contextual factors can influence the quality of food and meals in a more prominent role.

Interprofessional collaboration for children with physical disabilities: a scoping review.

Interprofessional collaboration is vital in the context of service delivery for children with physical disabilities. Despite the established importance of interprofessional collaboration and an increasing focus on research on this topic, there is no overview of the research. A scoping review was conducted to explore current knowledge on interprofessional collaboration for children with physical disabilities from the point of view of the actors involved. The steps of this review included identifying a research question, developing a protocol, identifying relevant research, selecting studies, summarizing and analyzing the data, and reporting and discussing the results. Through databases and studies from hand-searches, 4,688 records were screened. A total of 29 studies were included. We found that four themes: communication, knowledge, roles, and culture in interprofessional collaboration illustrate current knowledge on the topic. Interprofessional collaboration for children with physical disabilities is shown to be composed of these four themes, depending on the actors involved. Interprofessional collaboration is affected by how these four themes appear; they mainly act as barriers and, to a lesser extent, as facilitators for interprofessional collaboration. Whether and how the themes appear as facilitators need further exploration to support innovation of interprofessional collaboration.

The use of youth healthcare services and its association with health-related quality of life, physical and mental health and over-the-counter analgesics use in 13-19-year-old adolescents: a cross-sectional study.

BACKGROUND: Youth healthcare services in Norway include a public health nurse (PHN) at school and local youth health centres (YHCs). They provide health services for all adolescents free of charge, focusing on health promotion and disease prevention. The present study aimed to assess possible associations between health-related quality of life (HRQoL), physical and mental health, over-the-counter analgesics (OTCA) use and use of youth healthcare services among 13-19-year-old adolescents. METHODS: This study was based on national, cross-sectional data from the Ungdata Survey conducted in 2022. The sample was comprised of 16 482 adolescents. Multiple logistic regression was used to analyse the associations between HRQoL, headaches, selected physical symptoms, psychological distress, use of OTCA, PHN availability, sociodemographic variables, and use of the PHN at school or at a YHC. The KIDSCREEN-10 was used to measure HRQoL, and the Hopkins Symptoms Checklist 10 was used to measure symptoms of psychological distress. RESULTS: Girls used the youth healthcare services more frequently than boys. Better HRQoL was significantly associated with fewer visits to the PHN at school. Girls reported lower HRQoL and mental health, and more pain and frequent OTCA use than boys. When having symptoms of psychological distress, boys had greater odds of visiting the PHN at school than girls. For girls in senior high school, headaches and OTCA use were strongly associated with visiting the PHN at school and the YHC. In senior high school, boys with an immigration background had greater odds of visiting the YHC than native Norwegian boys, while girls with an immigration background were less likely to visit the YHC than native Norwegian girls. CONCLUSIONS: Our results show that more girls than boys use youth healthcare services. When adolescents experience pain, have mental problems, use OTCA, or report low levels of HRQoL, they have greater odds of using youth healthcare services. Youth healthcare services offer excellent opportunities to support and follow up with adolescents. The findings provide important insights into youth healthcare services used by adolescents for various stakeholders, including PHNs and policy makers, with potential implications for future public health efforts.

Pain in Adolescence: Maternal and Paternal Factors Affecting Adolescents' Pain in Norway-A Cross-Sectional Study.

BACKGROUND: Pain in adolescence is considered a worldwide concern. Adolescents' pain affects family functioning. However, bidirectional associations should be considered as parental determinates such as pain, stress, and sociodemographic factors are also shown to influence pain in adolescence. OBJECTIVES: This study explored the associations between maternal and paternal sociodemographic factors, pain, and stress and adolescents' pain, and stress on adolescents' pain. METHODS: In total, 508 school-based Norwegian adolescents with a corresponding parent were included. All adolescents completed an electronic survey during school hours, and their respective parents responded electronically. The survey included sociodemographic data, the Perceived Stress Questionnaire, and the Brief Pain Inventory. RESULTS: Herein, 385 adolescents reported an average pain of 2.1 (SD, 1.9), and 308 of the participating parents reported an average pain of 1.6 (SD, 1.8). Regressions stratified by parental gender revealed nonsignificant associations in fathers' study variables predicting adolescents' pain. However, having the highest maternal educational level (p ≤ 0.01) and working part-time (p ≤ 0.01) were associated with lower pain in adolescents. CONCLUSIONS: The findings of this study demonstrated that sociodemographic factors such as high educational status in mothers and mothers working part-time were associated with lower pain in Norwegian adolescents. These findings highlight the importance of a holistic approach to pain management in adolescence.

Sleep duration in schooldays is associated with health-related quality of life in norwegian adolescents: a cross-sectional study.

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 school-based 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.

'Struggling to participate in everyday life': emerging adults' experiences of living with long-term health challenges.

AIM: To gain a deeper understanding of the experiences of participation in the everyday life of emerging adults living with long-term health challenges and how this influences their own quality of life. METHODS: Using an explorative study design, data were collected through in-depth interviews with a sample of 12 young people aged 18-29 years living with long-term health challenges in Norway. FINDINGS: The analysis identified one overarching theme of struggling to participate in everyday life, and four subthemes: the notion of being independent but also dependent, experiencing mismatch between needs and support, experiencing deprivation of spontaneity and feeling uncertain about the future. The emerging adults experienced difficulties with participation in key areas of life such as education, employment and leisure activities. Associated symptoms of their diagnosis, limited physical abilities and lack of sufficient support made it hard to participate in everyday life the way they aspired to. CONCLUSION: The challenges of living with a long-term health challenge as an emerging adult contributed to limitations in participation in different areas of life that was perceived as important for their quality of life.

Use of KIDSCREEN health-related quality of life instruments in the general population of children and adolescents: a scoping review.

PURPOSE: Subjectively assessing health related quality of life (HRQoL) in children and adolescents is increasingly important in the public health field. One valid and widely used generic HRQoL instrument is the KIDSCREEN questionnaire. The aim of this study was to map all studies using KIDSCREEN instruments in the general population of children and adolescents aged 6-18 years. METHODS: A scoping review was conducted. The search strategy was formulated according to the Preferred Reporting Items for Systematic Reviews and Scoping Reviews guidelines. The databases Cinahl, socINDEX, Medline, Embase, APA Psychinfo, Scopus, and Eric were searched in October 2021. RESULTS: In total, 1365 papers were eligible for screening, 1031 were excluded and 334 reports were read in full. 252 reports were included. KIDSCREEN studies in the general population was predominantly conducted in Europe (n = 211). Most studies (n = 179) had a cross sectional design, while few experimental studies (n = 24) were found. The three KIDSCREEN versions comprising of 10, 27 and 52 items, were equally distributed between studies. The self-reported version (n = 225) of the KIDSCREEN instrument was more prevalent than the proxy version, while few studies discussed a cut point. Study contexts reflected international trends of public health challenges, commonly including mental- and psychosocial health, physical activity, socioeconomic status, and obesity. CONCLUSION: KIDSCREEN is widely used in cross sectional studies assessing common public health challenges. Experimental and longitudinal assessments, possibly including relevant cut offs remain mainly unexplored and are recommended for future research.

Unpacking the Public Health Triad of Social Inequality in Health, Health Literacy, and Quality of Life-A Scoping Review of Research Characteristics.

Social inequalities in health, health literacy, and quality of life serve as distinct public health indicators, but it remains unclear how and to what extent they are applied and combined in the literature. Thus, the characteristics of the research have yet to be established, and we aim to identify and describe the characteristics of research that intersects social inequality in health, health literacy, and quality of life. We conducted a scoping review with systematic searches in ten databases. Studies applying any design in any population were eligible if social inequality in health, health literacy, and quality of life were combined. Citations were independently screened using Covidence. The search yielded 4111 citations, with 73 eligible reports. The reviewed research was mostly quantitative and aimed at patient populations in a community setting, with a scarcity of reports specifically defining and assessing social inequality in health, health literacy, and quality of life, and with only 2/73 citations providing a definition for all three. The published research combining social inequality in health, health literacy, and quality of life is heterogeneous regarding research designs, populations, contexts, and geography, where social inequality appears as a contextualizing variable.

The relationship between stress and health-related quality of life and the mediating role of self-efficacy in Norwegian adolescents: a cross-sectional study.

BACKGROUND: During the transitional phase from childhood to adulthood, adolescents encounter many changes and challenges. Stress is associated with reduced health-related quality of life (HRQOL) in adolescents and, thus, impacts all aspects of their life. Adolescents' thoughts and beliefs in their capacity may be essential with regard to their subjective perception of stress and coping with it. Insights into the complexity of stress and exploration of the possible underlying mechanisms in adolescence are needed. We sought to describe stress, HRQOL, and self-efficacy and explore the association between stress and HRQOL by testing for self-efficacy as a possible mediator in adolescents. METHODS: In total, 696 school-based adolescents aged 14-15 years participated in this study. Participants were recruited from 22 schools in the Eastern and Southern parts of Norway. All participants completed an electronic survey in their respective classrooms. The survey included demographic data, the Perceived Stress Questionnaire, the KIDSCREEN-27 questionnaire measuring HRQOL, and the General Perceived Self-Efficacy Scale. Statistical analyses were conducted using the PROCESS macro for SPSS Statistics software by Andrew Hayes model 4. RESULTS: Descriptive analyses revealed overall low levels of stress with a score of 0.29 (SD, 0.15). Nevertheless, stress was negatively associated with all HRQOL subscales: physical well-being (B = - 25.60), psychological well-being (B = - 38.43), autonomy and parents (B = - 28.84), social support and peers (B = - 21.05), and school environment (B = - 30.28). Furthermore, these respective associations were all mediated by self-efficacy, which explained approximately one-fifth of the reduction in HRQOL. The highest degree of mediation and, thus, the largest indirect effect was estimated for the HRQOL subscale physical well-being (31.7%). CONCLUSIONS: Our findings extend prior research on the mechanisms underlying the relationship between perceived stress and HRQOL in adolescents. They demonstrated that perceived stress explained most of the reduction in the HRQOL after adjusting for the effect of self-efficacy. Hence, stress itself appears to be an important target for future interventions to enhance HRQOL, rather than purely focusing on increasing self-efficacy to enhance the HRQOL in adolescents. Our findings highlight the importance of a better understanding of the underlying mechanisms to develop strategic and accurate interventions for adolescents.

Health-related quality of life in parents of adolescents one year into the COVID-19 pandemic: a two-year longitudinal study.

AIM: For many adults, their role as a parent is a vital part of their life that may influence their health-related quality of life (HRQOL) and vary with the age of their child. The aim of the present study was to describe and compare sociodemographic and psychological factors, pain and HRQOL in parents of adolescents assessed at baseline and 2 years later,-during the COVID-19 pandemic. METHODS: A longitudinal study of 309 parents from the general Norwegian population was conducted. The parents were chosen based on their adolescent's school belonging and responded to a web-based questionnaire. We used data collected at baseline (T1), when the adolescents were aged 14-15 years (2018/2019), and two years later (T2), in 2021, when the COVID-19 pandemic was ongoing. The response rate was 55%. HRQOL was assessed using RAND-36. Data were analysed using McNemar tests, paired samples t-tests and multiple linear regression analyses. RESULTS: Of the participants, 82% were mothers and 18% fathers. From T1 to T2, the average pain score increased, 1.6 (95% CI [-1,4; 1.8]) vs 1.8 (95% CI [1,6; 2.0]), the pain interference emotion score increased, 1.6 (95% CI [1.3; 1.9]) vs 1.8 (95% CI [1.5; 2.1]), and a larger proportion reported pain duration > 3 months (44% vs 50%, p = 0.014). The parents were more lonely, 12.8 (95% CI [12.3; 13.3]) vs 13.7 (95% CI [13.2; 14.2]), and reported lower RAND-36 mental component summary (MCS) scores, 52.2 (95% CI [51.3; 53.2]) vs 50.9 (95% CI [49.8; 52.0]). There were no significant associations between gender, sociodemographic factors, psychological factors, pain at T1 and changes in RAND-36 physical component summary (PCS). A positive change in MCS from T1 to T2 was predicted by working part time, B = 5.22 (95% CI [1.05; 9.38]) (ref no paid work) and older age, B = 0.24, (95%CI [-001; 0.42]), and there was a negative change with stress, B = -17.39, (95%CI [-27.42; -7.51]). CONCLUSION: The parents experienced more pain and were lonelier, and more reported reduced mental HRQOL. However, the changes appear to be of limited clinical significance.

The Parent Health Literacy Questionnaire (HLQ-Parent). Adaptation and validity testing with parents of children with epilepsy.

AIMS: The aim of this study was to adapt the Health Literacy Questionnaire (HLQ) in English and Norwegian for use with parents. METHODS: The research group evaluated all HLQ items and, where relevant, modified them to refocus the attribution of care to that of a child by a parent. Five cognitive interviews with parents were undertaken to gain a detailed depiction of the meanings and processes they used to respond to the HLQ items. Assessment of the psychometric properties of the revised HLQ was undertaken using data from a cross-sectional survey of 254 parents of children with epilepsy. Analysis included internal consistency (Cronbach's alpha) and confirmatory factor analysis (CFA). RESULTS: Some 22 out of 44 items and the names of three domains were modified (e.g. attribution changed from 'me' to 'my child'). Cognitive interviews indicated that parents interpreted the HLQ-Parent items in the way intended. All but three factor loadings were high to acceptable. All nine HLQ scales showed satisfactory to good internal consistency (Cronbach's alpha 0.70 to 0.87). When fitting one-factor CFA models, correlated residuals were required for four scales to generate an acceptable fit. One scale, '8. Ability to find good health information', required inclusion of two correlated residuals to generate an acceptable CFA model fit, indicating that further work on this scale is warranted. CONCLUSIONS: The results from both the adaptation process and the CFA analysis supported the relevance, understanding and theoretical structure of the instrument in a parental context.

Changes in health-related quality of life in adolescents and the impact of gender and selected variables: a two-year longitudinal study.

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-efficacy, loneliness, and stress on HRQOL changes over time. Further, to assess HRQOL stratified by gender. METHODS: A longitudinal study involving 211 adolescents was conducted. Sociodemographic variables, pain, self-esteem, self-efficacy, 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 significantly, independently associated with a reduction in HRQOL change scores for four of the five KIDSCREEN subscales. Time was significantly associated with a reduction in physical and psychological well-being. Self-efficacy and self-esteem were significantly associated with an increase in HRQOL change scores for four and two subscales, respectively. Male gender was significantly negatively associated with changes in social support and peers compared to female gender. CONCLUSION: Our results demonstrated a significant 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 significant negative impact on HRQOL changes, whereas self-esteem and self-efficacy have a significant positive impact. Our results highlight the importance of increased understanding regarding factors associated with changes in adolescents' HRQOL to enable accurate and strategic interventions.

Sleep patterns and psychosocial health of parents of preterm and full-born infants: a prospective, comparative, longitudinal feasibility study.

BACKGROUND: The early birth and hospitalization of a preterm infant in neonatal intensive care unit can produce several emotional and behavioural responses including sleep problems for parents. Few studies have explored sleep and its associations with health and HRQoL over time in this vulnerable parent population. This purpose of this study was to evaluate the feasibility of a prospective, comparative, longitudinal study of the sleep patterns and psychosocial health of preterm and full-born infants' parents during the first postpartum year. METHODS: A prospective, comparative, longitudinal feasibility study was conducted. Parents of preterm infants were compared to parents of full-born infants to identify if there were differences in outcomes between the groups. The parents were instructed to wear actigraphs and complete sleep diaries for two consecutive weeks, and responded to a digital questionnaire covering stress, insomnia, fatigue, depression, social support, self-efficacy, and health-related quality of life. Survey data were collected at infant ages of 2, 6, and 12 months, actigraphy and sleep diary data were collected at infant age of 2 months only. Descriptive analysis was used to describe recruitment and attrition rates. Differences between completers and dropouts were analysed with a chi-square test (categorical data) and Mann-Whitney-Wilcoxon test for two independent samples (continuous variables). RESULTS: Between June 2019 and March 2020, 25 parents of a preterm infant and 78 parents of a full-born infant were recruited from four neonatal intensive care units and two maternity wards, respectively, in four Norwegian hospitals. Feasibility was predefined as recruiting ≥ 75 parents each of preterm and full-born infants. The target for the full-born group was reached. However, the preterm group recruitment was challenging. Actigraphs, sleep diaries, and questionnaires were evaluated as feasible for use in a future study. Attrition rates were high in both groups at 6 and 12 months. No parent-related characteristics were associated with participation at 6 months. At 12 months, dropouts had a statistically significantly lower age in the full-born group (both parents) and higher age and body mass index in the preterm group (fathers). CONCLUSIONS: A longitudinal study is feasible; however, procedural changes, including using active methods and contacting participants, are necessary to increase the recruitment of preterm infants' parents.

Health-related quality of life, health literacy and COVID-19-related worries of 16- to 17-year-old adolescents and parents one year into the pandemic: a cross-sectional study.

BACKGROUND: The uncertain and challenging situation caused by the COVID-19 pandemic affects adolescents and their parents in an exceptional way. More knowledge of health-related quality of life (HRQoL), health literacy (HL) and COVID-19-related worries in adolescents and parents 1 year into the pandemic is needed. The present study aimed to describe HRQoL, HL and COVID-19-related worries of 16- to 17-year-old adolescents and parents of adolescents. Further, to assess the strength of associations between gender, HL, COVID-19-related worries and HRQoL. METHODS: A cross-sectional study involving 215 adolescents and 320 parents was conducted, exploring HRQoL, HL, COVID-19-related worries and sociodemographic variables. KIDSCREEN-10 and RAND-36 were used to measure HRQoL. Data were analyzed using bivariate methods, multiple linear regression and robust regression. RESULTS: Adolescents' HRQoL was notably lower compared to previous Norwegian studies and European norms. Parents' HRQoL was comparable to Norwegian norms. Adolescents and parents reported moderate-to-high HL and high degrees of COVID-19-related worries. Females reported significantly lower HRQoL and more worries compared to males. In adolescents, higher HL was significantly associated with higher HRQoL. COVID-19-related worries were not significantly associated with HRQoL. In parents, higher HL in the "understand health information" domain was significantly associated with higher HRQoL for mental well-being (mental component sum scores [MCS]) and with lower HRQoL for physical well-being (physical component sum scores [PCS]). Being worried a lot about infecting others and about family/friends becoming sick was significantly associated with higher MCS and lower MCS, respectively. COVID-19-related worries were not significantly associated with PCS. CONCLUSIONS: Our results indicate that the pandemic has a major negative impact on adolescents' HRQoL. Parents' HRQoL remained unchanged and comparable to previous studies. Our study demonstrates that HL, gender and COVID-19-related worries are significantly associated with adolescents' and parents' HRQoL, indicating that efforts aimed at increasing their HL might indirectly affect their HRQoL as well and that gender-specific interventions or strategies could be beneficial.

App-based intervention among adolescents with persistent pain: a pilot feasibility randomized controlled trial.

BACKGROUND: Persistent pain in adolescence adversely affects everyday life and is an important public health problem. The primary aim was to determine the feasibility of an 8-week app-based self-management intervention to reduce pain and improve health-related quality of life in a community-based population of adolescents with persistent pain. A secondary aim was to explore differences in health outcomes between the intervention and control groups. METHODS: A sample of 73 adolescents aged 16-19 years with persistent pain from a community-based population were randomized into 2 groups. The intervention group received the Norwegian culturally adapted version of the iCanCope with PainTM app, which includes symptom tracking, goal setting, self-management strategies, and social support. The attention control group received a symptom tracking app. Feasibility was assessed as attrition rates and level of engagement (interactions with the app). The secondary outcomes included pain intensity, health-related quality of life, self-efficacy, pain self-efficacy, perceived social support from friends, anxiety and depression, and patient global impression. Statistical analyses were conducted using SPSS. RESULTS: Demographic and baseline outcome variables did not differ between the 2 groups. No differences were found between the participants completing the study and those who withdrew. Twenty-eight adolescents completed the intervention as planned (62% attrition). Both groups had a low level of app engagement. Intention-to-treat analysis (n = 19 + 14) showed no significant differences in outcomes between groups. However, the large effect size (Cohen's d = .9) for depression suggested a lower depression score in the intervention group. CONCLUSIONS: High treatment attrition and low engagement indicate the need for changes in trial design in a full-scale randomized controlled trial to improve participant retention. TRIAL REGISTRATION: The iCanCope with Pain Norway trial was retrospectively registered in Clinical Trials.gov (ID: NCT03551977 ). Registered 6 June 2018.

"It's hard to keep a distance when you're with someone you really care about"-A qualitative study of adolescents' pandemic-related health literacy and how Covid-19 affects their lives.

PURPOSE: The aim of this study was to explore how adolescents accessed, understood, appraised, and applied information on pandemic preventive measures, how their lives were impacted by long-lasting regulations and how they described their quality of life. METHODS: A qualitative design with focus group interviews was used to elaborate on the quantitative survey results obtained and analyzed in a previous survey study from the first phase of the Covid-19 pandemic. Five focus groups with seventeen adolescents were conducted digitally during the second pandemic phase in November and December 2020. The interview data were analyzed with directed content analysis. RESULTS: The adolescents reported using traditional media and official websites as sources for Covid-19 information. They engaged in preventive behavior, and washing hands and keeping a distance from strangers had become a habit. However, not being physically close to friends felt strange and unpleasant. The measure most frequently discussed was limiting social contact, which was a constant struggle. No one disputed the authorities' guidelines and rules, but the social restrictions caused boredom and despair, particularly due to interrupted schooling and missed opportunities to engage in life events, and freely socialize with friends. CONCLUSION: The adolescents gave an overall impression of being health literate, which corresponds well with the results from our previous survey study. Their descriptions of how they translated protective measures into their everyday lives demonstrate that they took responsibility and accepted personal costs for the collective good. However, life with social restrictions decreased their quality of life.

Infant colic, young children's temperament and sleep in a population based longitudinal cohort study.

BACKGROUND: Colic and sleep problems are common among infants, constitute challenges and distress for parents, and are often reasons for seeking help from health professionals. The literature debates whether infant colic and sleep problems are linked together or not. Further, limited evidence exists on how colic impacts on child temperament and sleep during early childhood. Thus, the purpose of this study was to increase our knowledge of the characteristics of infants with a history of colic compared to infants without, and to study how infant colic is associated with the development of child temperament and sleep over time. METHODS: The study is based on The Norwegian Mother, Father and Child Cohort Study (MoBa), a population-based cohort study conducted by the Norwegian Institute of Public Health. This sample contains 88,186 mothers and children. Data was retrieved from questionnaires distributed to mothers at recruitment (in pregnancy) and when the child was 6 months, 18 months, 3 years, and 5 years. Data was analysed using linear mixed models and GLM models for repeated measures. RESULTS: At 6 months, infants with reported colic are described as fussier, present more sleeping problems, are breastfed less, and the families visit the child health centre more often when compared to the non-colic group. Mothers of children with reported colic perceive their children's temperament significantly more challenging from the age of 6 months to 5 years. Further, children with reported colic were more likely to sleep less than recommended (22%) and to have more frequent night awakenings (14%) than usual for their age (6 months to 5 years). CONCLUSION: Infant colic often occurs together with other signs of regulatory problems which may amplify the load on the parents. Moderate differences in temperament and sleep-problems across time, between those with colic and those without, indicate that the diagnosis of colic is moderately associated with later behavioural difficulties. However, it is demanding for the parents, and important to be aware of and act upon symptoms of colic in the child health centres to reduce the parents' load and prevent adverse long-term outcomes.

Definitions and measurement of health literacy in health and medicine research: a systematic review.

OBJECTIVES: The way health literacy is understood (conceptualised) should be closely linked to how it is measured (operationalised). This study aimed to gain insights into how health literacy is defined and measured in current health literacy research and to examine the relationship between health literacy definitions and instruments. DESIGN: Systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. DATA SOURCES: The MEDLINE, PsycINFO, ERIC and CINAHL databases were searched for articles published during two randomly selected months (March and October) in 2019. ELIGIBILITY CRITERIA: We included articles with a quantitative design that measured health literacy, were peer-reviewed and original, were published in the English language and included a study population older than 16 years. DATA EXTRACTION AND SYNTHESIS: Six researchers screened the articles for eligibility and extracted the data independently. All health literacy definitions and instruments were considered in relation to category 1 (describing basic reading and writing skills, disease-specific knowledge and practical skills) and category 2 (social health literacy competence and the ability to interpret and critically assess health information). The categories were inspired by Nutbeam's descriptions of the different health literacy levels. RESULTS: 120 articles were included in the review: 60 within public health and 60 within clinical health. The majority of the articles (n=77) used instruments from category 1. In total, 79 of the studies provided a health literacy definition; of these, 71 were in category 2 and 8 were in category 1. In almost half of the studies (n=38), health literacy was defined in a broad perspective (category 2) but measured with a more narrow focus (category 1). CONCLUSION: Due to the high degree of inconsistency between health literacy definitions and instruments in current health literacy research, there is a risk of missing important information about health literacy considered be important to the initial understanding of the concept recognised in the studies.
