Examining the relationship between non-suicidal self-harm and suicidality within the past 12-months and gaming problems in Norwegian full-time students.

BACKGROUND: Although gaming problems are associated with poor mental health, few population-based studies have examined its association with self-harm and suicidality. This study investigates the association between gaming problems, non-suicidal self-harm and suicidality within the past year, stratified by sex among Norwegian full-time students. METHODS: Data derived from the Norwegian Students' Health and Wellbeing Study 2022 (N = 59,544). The respondents were categorized into non-gamers, recreational gamers, engaged gamers, problematic gamers, and addicted gamers based on the Game Addiction Scale for Adolescents. Log-link binomial regression models, stratified by sex, adjusted for age, were used to estimate the risk ratio of non-suicidal self-harm (ideation and behavior) and suicidal behaviors (ideation and attempt) across different levels of gaming problems. RESULTS: Among females, the risk of non-suicidal self-harm and suicidal ideation increased from non-gamer to problem gamer, with no differences between problem and addicted gamers. Among males, the risk of non-suicidal self-harm increased from non-gamers to engaged gamers, but no differences were observed between engaged, problematic, and addicted gamers. No sex × gaming category interaction was observed for suicide attempts. Engaged and addicted gamers had higher risks of suicide attempt than non-gamers and recreational gamers. CONCLUSIONS: Gaming problems are associated with increased risk of non-suicidal self-harm and suicidal ideation among females. Among males, no differences were observed between engaged, problem and addicted gamers. The results highlight sex when studying health related outcomes and their association to level of gaming problems. Longitudinal studies are warranted to uncover the temporal mechanisms between IGD, non-suicidal self-harm and suicidality.

The association of psychological distress and economic and health worries with tobacco smoking behavior during the COVID-19 pandemic: a two-year longitudinal cohort study.

BACKGROUND: The COVID-19 pandemic and other life events may trigger worries and psychological distress. These impacts may lead to unhealthy behaviors, such as tobacco smoking, but the degree of such associations is unclear. The current three-wave longitudinal study examines changes in tobacco smoking in Norway between 2020 and 2022 and their associations with psychological distress as well as health- and economy-related worries. METHODS: Data were collected in April 2020 (baseline), January 2021, and January 2022 in Bergen, Norway, from an online longitudinal population-based survey. Smoking tobacco (the outcome variable) was dichotomized based on the responses to the question of whether participants smoked cigarettes or not. Tobacco smoking and its associations with psychological distress were assessed among 24,914 participants (response rate 36%) in a mixed model regression presented with coefficients and 95% confidence intervals (CI), adjusting for COVID-19-related worries, home office/study, occupational situation, age, gender, education, having children below 18 years living at home, living alone, and alcohol consumption. RESULTS: A total of 10% of the study sample were current smokers at baseline. At baseline, smoking tobacco was associated with high levels of psychological distress (absolute difference 13%, 95% CI 10%; 15%), advanced age (50-59 years: 11%, CI 10%; 13%), and hazardous alcohol use (4%, CI 3%; 5%) compared to their counterparts. Higher education (-5%, CI -6%; -4%), working from home (-4%, CI -5%; -4%), and higher physical activity levels (-4%, CI -5%; -3%) were associated with non-smoking. The prevalence of smoking among individuals experiencing severe psychological distress decreased slightly over time (-2% per year, CI -3%; -1%). CONCLUSIONS: Smoking was associated with severe psychological distress, advanced age, and hazardous alcohol use at baseline; non-smoking was associated with high education, working from home, and high physical activity. Nevertheless, the smoking rate among individuals experiencing severe psychological distress slightly decreased over the course of the COVID-19 pandemic.

Establishing the Association Between Snus Use and Mental Health Problems: A Study of Norwegian College and University Students.

INTRODUCTION: Smoking and mental health problems are public health concerns worldwide. Studies on smoke-free tobacco products, especially snus are scarce. Snus is considered less harmful than smoking and in the United States allowed to be marketed accordingly, but may still add to the burden of disease. AIMS AND METHODS: Data stem from the Norwegian Students' Health and Wellbeing Study (SHoT study) in 2018 (162 512 invited, 50 054 (30.8%) completed). Smoking, snus use, health service and medication usage and mental health problems, including the Hopkins Symptom Checklist-25 (HSCL-25), were assessed using self-report. The aims were to explore the associations between smoking and snus use and mental health problems and treatments. Furthermore, the association between both daily smoking and daily snus use and mental health problems. Associations were tested with χ2-, t-tests, and logistic regression. RESULTS: Daily snus users had 38% increased odds (odds ratio [OR]: 1.38, CI: 1.30 to 1.46), and daily smokers had 96% increased odds (OR: 1.96, CI: 1.65 to 2.34) of having a high HSCL-25 score, adjusted for gender, low socioeconomic status (SES), using tobacco, participating in therapy and using antidepressants daily. CONCLUSIONS: Both daily smoking and daily snus use were associated with an increased level of mental health problems. The adjusted probability for mental health problems was lower for snus use; however, snus use prevalence was tenfold in our sample. IMPLICATIONS: Despite the lack of causal and directional conclusions, these associations may have implications for future legislation on snus. They also highlight the importance of more research, especially as snus is considered less harmful and seemingly replacing smoking in Norway.

A cross-sectional study of the relationship between injuries and quality of life, psychological distress, sleeping problems, and global subjective health in adults from three Norwegian counties.

BACKGROUND: Studies examining associations between injuries and outcomes like quality of life and psychological distress are important to understand a broader range of possible consequences of injuries for population health. AIMS: The aim of this study was to examine associations between self-reported injury and quality of life, psychological distress, sleeping problems, and global subjective health. METHODS: The sample was drawn from the Norwegian National Population Register. Data were collected among the general adult populations in three Norwegian counties in 2019-2020 (response rate 45.3%, n = 74,030). Exposure variables were being injured during the last 12 months, cause of injury (if more than one, the most serious one), and functional impairment due to injuries. Outcome variables included measures of total quality of life, global quality of life, positive affect, negative affect, positive social relations, social capital (trust, belongingness, feeling safe), psychological distress, sleep problems, loneliness, and global subjective health. Data were analysed with General Linear Modelling in SPSS Complex. RESULTS: Reporting to have been injured once during the last 12 months was associated with slightly elevated levels of psychological distress, sleeping problems, and loneliness, and lower mean scores on quality-of-life indicators and global subjective health. Reporting being injured twice or more showed more pronounced contrasts to the reference group on the same outcomes, with Cohen's d-values (absolute numbers) ranging from 0.17 to 0.54. For having been victim to violence, d-values ranged from 0.30 to 1.01. Moderate functional impairment due to injuries was associated with less favourable scores on all outcomes (d ranging from 0.15 to 0.71). For strong functional impairment d-values ranged from 0.35 to 1.17. CONCLUSIONS: Elevated levels of distress and reduced levels of quality of life are particularly associated with multiple injuries, being victim to violence, and functional impairment due to injuries. Prospective, longitudinal studies with high quality instruments and large samples, allowing adjustment for baseline values of outcome variables, and utilization of state-of-the-art statistical techniques, would bring this research closer to examining causality.

Potential traumatic events and symptoms of post-traumatic stress in unaccompanied refugee minors-a comparison with youth in foster care.

Building knowledge on how child welfare services (CWS) should tailor services for unaccompanied refugee minors (URMs) is important. URMs and youth in foster care are high-risk groups taken care of by the CWS in Norway. Little is known on whether knowledge gained from youth in foster care can inform services for URMs, and if these groups are comparable in terms of experiences of potential traumatic events (PTEs) and post-traumatic stress disorder (PTSD) symptom load. Eighty-one URMs reported PTEs and PTSD-symptoms using an adapted version of the Child and Adolescent Trauma Screen (CATS). Responses were described and compared with a sample of 303 youth in foster care in linear regression models. We present relative risks (RR) and standardized mean differences (SMD) for the PTEs and the PTSD subscale and total score between the groups in forest plots. URMs had experienced a mean (standard deviation) of 6.4 (3.4) PTEs and 43.9% reported to have PTSD-symptoms at or above the clinical cut off. Compared to the foster youth, URMs reported more exposures of interpersonal violence outside of the family (RRs ranging from 66.4 [95%CI 18.1; 243.5) to 1.3 (1.0, 1.5)], and more PTSD-symptoms in the re-experiencing subscale [SMD = 0.3 (95% CI 0.1, 0.6)]. The frequency and types of PTEs and the PTSD-symptom load and profile among URMs and youth in foster care differed. Findings underscore the importance of qualified and targeted care for URMs, and that this care should differ to that of other high-risk groups in the CWS.

Quality of life among young people in Norway during the COVID-19 pandemic. A longitudinal study.

In this study, we aimed to examine health-related quality of life during the COVID-19 pandemic among a general sample of young people in Norway aged 11-19 years. More specifically, we examine: (1) Change over 2 time-points in five health-related quality of life dimensions, (2) Whether sociodemographic- and COVID-19-related factors contributed to change in these five dimensions, (3) Whether parental stress and socioeconomic status at T1 interacted with change in health-related quality of life across T1 and T2. Data collection lasted from April 27th to May 11th, 2020 (T1), and from December 16th, 2020, to January 10th, 2021 (T2). Youth aged 11-19 years (N = 2997) completed the KIDSCREEN-27, COVID-19 related and sociodemographic items. Parents (N = 744) of youth aged 15 years and younger completed the parental stress scale and sociodemographic items. Physical and psychological wellbeing declined significantly from March to December 2020. Subscale scores for social support and peers increased. Controlling for a broad number of sociodemographic and COVID-19-related factors did not make an overall impact on the estimates. Those worried about infection, older aged, girls, and youth born outside Norway had a steeper decline in health-related quality of life subdimensions from T1 to T2. In the wake of the COVID-19 pandemic, we warrant special attention to the recovery of youth's physical and psychological wellbeing.

Negative Life Events, Protective Factors, and Substance-Related Problems: A Study of Resilience in Adolescence.

BACKGROUND: There is compelling evidence for an association between negative life events (NLE) and substance-related problems (SRP) during adolescence. The literature is, however, still limited with regards to protective factors for SRP among adolescents exposed to NLE. METHODS: A large population-based survey including 9,611 Norwegian adolescents aged 16 to 19 years, comprised the dataset of this study. The main explanatory variable was NLE. The main outcome variable was SRP, assessed by the CRAFFT scale. Potential protective factors were measured with five subscales from the Resilience Scale for Adolescents (READ) questionnaire. The potential protective factors and sex were explored as moderators for the associations between NLE and SRP. RESULTS: NLE were strongly associated with SRP. Four out of five potential protective factors (i.e., Goal Orientation, Self-confidence, Family Cohesion, and Social Support) showed evidence of a protective-stabilizing effect. Even if they had protective effect across all levels of exposure to NLE, these effects were even stronger for adolescents with high exposure. For Family Cohesion a protective-stabilizing effect was only evident for boys, while a direct protective effect was found for girls. Finally, Social Competence was the only factor that did not show any evidence of promoting resilience toward SRP. CONCLUSIONS: NLE had a strong relation with SRP in this study. Protective factors buffered against SRP for all adolescents - but particularly so for adolescents who had high exposure to NLE. These findings highlight the need for preventive efforts to strengthen protective factors that may promote resilience among adolescents at risk for SRP.

Emerging mental health problems during the COVID-19 pandemic among presumably resilient youth -a 9-month follow-up.

BACKGROUND: The COVID-19 pandemic may have multifarious adverse effects on the mental health of some youth. To our knowledge, no study has followed young people beyond the first 6 months of the pandemic outbreak. The aim of this study was to examine 1) Change in internalizing, externalizing, and total mental health problems over two time-points with a nine-month interval during the COVID-19 outbreak and 2) Whether contextual and COVID-19-related factors contribute to change in mental health problems. METHODS: Youth within the municipality of Bergen aged 11-19 years were invited via SMS to participate in an online survey in April and again in December 2020. A total of 2997 (40% response rate) youth participated at baseline in the present study, and 1598 (53.3%) completed the second survey. At baseline, the mean age was 16.0 (standard deviations 1.7) years, about 60% were girls, and 93% were born in Norway. Comparison across time was approached using inferential statistics and mixed linear models with maximum likelihood estimation and mixed-effects logistic regression models. RESULTS: There was an overall increase in total mental health problems from the first weeks into lockdown to 9 months after the pandemic outbreak. The overall increase seems to be exclusively driven by internalizing difficulties, i.e., increases in emotional problems and peer problems. The level of externalizing difficulties, i.e., conduct problems and hyperactivity/inattention remained stable between the two time-points. CONCLUSIONS: Our results imply that in the wake of the pandemic, one should be aware of emerging mental health problems among presumably resilient youth, in addition to the more expected and pronounced mental health needs of vulnerable groups. Efforts to reach out to the general youth population with preventive measures in schools may be important actions to normalize the situation for young people, and to identify those in need of more targeted mental health interventions.

How the Norwegian population was affected by non-pharmaceutical interventions during the first six weeks of the COVID-19 lockdown.

AIMS: The aim of this study was to examine how the Norwegian general adult population was affected by non-pharmaceutical interventions during the first six weeks of the COVID-19 lockdown. We assessed quarantine, symptoms, social distancing, home office/school, work status, social contact and health-care contact through digital access and knowledge. METHODS: A cross-sectional survey was performed of 29,535 adults (aged 18-99) in Norway after six weeks of non-pharmaceutical interventions in March/April 2020. RESULTS: Most participants found the non-pharmaceutical interventions to be manageable, with 20% of all adults and 30% of those aged <30 regarding them as acceptable only to some or a limited degree. Sixteen per cent had been quarantined, 6% had experienced symptoms that could be linked to COVID-19 and 84% practiced social distancing. Eleven per cent reported changes in the use of health and social services. Three-quarters (75%) of those who had mental health or physiotherapy sessions at least monthly before the pandemic reported a reduction in their use of these services. A substantial reduction was also seen for home nursing, hospital services and dentists compared to usage before the non-pharmaceutical interventions. Immigrants were more likely to experience a reduction in follow-up from psychologists and physiotherapy. With regard to the use of general practitioners, the proportions reporting an increase and a reduction were relatively equal. CONCLUSIONS: The non-pharmaceutical interventions were perceived as manageable by the majority of the adult general population in Norway at the beginning of the COVID-19 pandemic. A substantial proportion of adults <30 years old experienced difficulties with social distancing, and those >70 years old lacked the digital tools and knowledge. Further, immigrant access to health services needs monitoring and future attention.

Negative experiences, social exclusion and unwanted attention on social media: exploring the association with adolescent alcohol use.

BACKGROUND: Adolescents' presence on Social Media (SoMe) facilitates peer connections making them susceptible to peer-influences and approval. Negative experiences on SoMe can affect adolescent stress and wellbeing, impelling their use of alcohol. This paper provides a novel understanding of the relationship between negative experiences on SoMe and key indicators of alcohol use in adolescents. METHODS: Data was collected from upper secondary school students (n = 3528, ages 16-19, 45% boys) in Bergen (Norway) using a web-based questionnaire during school-hours in 2020 and 2021. Dependent variables were alcohol consumption, binge drinking and scoring ≥ 2 points on the CRAFFT instrument screening for substance use problems in adolescents. Independent variables were two scales indicating "negative acts and exclusion" and "unwanted attention from others". Covariates included age, gender, country of birth and subjective socioeconomic status. Results are presented as relative risk ratios (RRR), odds ratios (OR) and incidence rate ratios (IRR) with 95% confidence intervals. RESULTS: Using multinomial logistic regression models, "negative acts and exclusion" and "unwanted attention" were positively associated with trying alcohol (OR: 1.50 (95% CI 1.28-1.76) and 1.86 (95% CI 1.66-2.09) respectively, both p ≤ 0.001), with frequency and amount of alcohol consumed. Findings from logistic regression models indicated that "negative acts and exclusion" and "unwanted attention" were positively associated with i. CRAFFT-caseness (OR: 2.13 and 1.86) and ii. frequent binge drinking (OR: 1.55 and 1.89). CONCLUSION: Both exclusion and unwanted attention on SoMe were associated with indicators of problematic drinking, including frequency, quantity, and consequences related to alcohol.

Met and unmet need for mental health care before and during the COVID-19 pandemic.

There is a concern that the coronavirus disease 2019 (COVID-19) pandemic will generate large unmet needs for mental health care. Using data from an epidemiological psychiatric diagnostic interview survey (n = 2159) conducted on a probability sample from the general population, the proportions of met and unmet need for mental health care among individuals with and without mental disorders were compared before and during the COVID-19 pandemic. The results showed no statistical difference in met and unmet need for mental health care, but point estimates were suggestive of a higher unmet need for care among those with a current mental disorder after the lock-down period.

The gendered relationship between illicit substance use and self-harm in university students.

PURPOSE: To estimate associations between multiple forms of substance use with self-harming thoughts and behaviours, and to test whether gender is an effect modifier of these associations, both independently and along with perceived risk of cannabis use. METHODS: Data were drawn from the 2018 Norwegian Students' Health and Wellbeing Study (SHoT 2018). A national sample of n = 50,054 full-time Norwegian students (18-35 years) pursuing higher education completed a cross-sectional student health survey, including questions on past-year self-harm: non-suicidal thoughts of self-harm, non-suicidal self-harm, suicidal thoughts, and suicide attempt. Students reported their frequency of past-year alcohol use (range: never to ≥ 4 times/ week), illicit substance consumption, and perceived risk of cannabis use. The AUDIT and CAST screening tools measured problematic alcohol and cannabis consumption, respectively. We used logistic regression modelling adjusted for age, symptoms of depression and anxiety, and financial hardship (analytic sample range: n = 48,263 to n = 48,866). RESULTS: The most frequent alcohol consumption category (≥ 4 times/ week) was nearly always associated with more than a two-fold increased likelihood of self-harm. Less frequent alcohol consumption was associated with reduced odds of suicidal thoughts [monthly or less: OR = 0.87 (95% CI: 0.75-1.00), 2-4 times/month: OR = 0.79 (95% CI: 0.69-0.91), and 2-3 times/ week: OR = 0.83 (95% CI: 0.71-0.98)]. Problematic alcohol consumption was associated with most outcomes: odds ranging from 1.09 (95% CI: 1.01-1.18) for suicidal thoughts to 1.33 (95% CI: 1.00-1.77) for suicide attempt. There was evidence of multiple illicit substance by gender interactions: consumption of all but one illicit substance category (other drug use) was associated with all four forms of self-harm for women, but findings among men were less clear. Among men, only one illicit substance category (stimulant) was associated with most forms of self-harm. Women, but not men, who perceived cannabis use as a health risk were more likely to experience non-suicidal thoughts as cannabis consumption increased, and with harmful consumption patterns. CONCLUSION: Frequent alcohol consumption is associated with increased risk of self-harm and suicidality for young women and men. Associations between illicit substance use and self-harm and suicidality appear stronger in women compared to men.

Nordic adolescents responding to demanding survey scales in boring contexts: Examining straightlining.

INTRODUCTION: Straightlining, or identical responses across all items within a multi-item scale, is often taken as an indication that responses to all items in a questionnaire are of poor quality. The purpose of this study was to examine straightlining on two scales: The Sense of Unity Scale (SUS) and the short version of the Warwick-Edinburgh Mental Well-being Scale (SWEMWBS). METHODS: Data stem from the 2017-2018 data collections in four Nordic countries of the Health Behaviour in School-children study (HBSC) (15-year-old students only; 50.9% girls; n = 5928). Data were weighted to adjust for oversampling of Swedish-speaking Finnish students and to equalize sample size across countries. The main analyses were done with general linear modeling with adjustments for cluster effects (school classes). RESULTS: The proportion with straightlining on SUS was 22.8%, varying from 5.8% among Swedish girls to 46.4% among Finnish boys. The proportion with straightlining on SWEMWBS was 18.4%, varying from 5.2% among Norwegian girls to 46.0% among Finnish boys. Straightlining on one of the scales correlated with straightlining on the other one. Straightlining tended to inflate Cronbach's α values and reduce number of factors in factor analyses. Associations between the two scales and external variables tended to be lower among straightlining students. Associations between external variables (other than SUS/SWEMWBS) are on average slightly weaker among straightliners. Straightlining students obtained more favorable scores on several resource-related variables. CONCLUSION: Although some problems have been identified, straightlining does not serve well as a general indicator of poor data quality.

Trends in self-reported psychological distress among college and university students from 2010 to 2018.

BACKGROUND: An increase in reported psychological distress, particularly among adolescent girls, is observed across a range of countries. Whether a similar trend exists among students in higher education remains unknown. The aim of the current study was to describe trends in self-reported psychological distress among Norwegian college and university students from 2010 to 2018. METHODS: We employed data from the Students' Health and Wellbeing Study (SHoT), a nationwide survey for higher education in Norway including full-time students aged 18-34. Numbers of participants (participation rates) were n = 6065 (23%) in 2010, n = 13 663 (29%) in 2014 and n = 49 321 (31%) in 2018. Psychological distress was measured using the Hopkins Symptom Checklist-25 (HSCL-25). RESULTS: Overall, a statistically significant increase in self-reported psychological distress was observed over time across gender and age-groups. HSCL-25 scores were markedly higher for women than for men at all time-points. Effect-size of the mean change was also stronger for women (time-by-gender interaction: χ2 = 70.02, df = 2, p < 0.001): in women, mean HSCL-25 score increased from 1.62 in 2010 to 1.82 in 2018, yielding a mean change effect-size of 0.40. The corresponding change in men was from 1.42 in 2010 to 1.53 in 2018, giving an effect-size of 0.26. CONCLUSIONS: Both the level and increase in self-reported psychological distress among Norwegian students in higher education are potentially worrying. Several mechanisms may contribute to the observed trend, including changes in response style and actual increase in distress. The relative low response rates in SHoT warrant caution when interpreting and generalising the findings.

Sexual harassment and assault predict sleep disturbances and is partly mediated by nightmares: Findings from a national survey of all university students in Norway.

Sexual harassment and assault is common in most domains of society, and has been linked to several adverse outcomes, including reduced sleep quality. However, less is known about the possible impact of sexual harassment and assault on various sleep problems among university students. In a sample of 49,051 students in Norway (69.2% women), we examined i) the associations of varying extents of sexual harassment (unwanted sexual comments, looks or gestures, photographs, indecent exposure, and physical harassment) and sexual assault (attempted or completed rape), with meeting Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic criteria of insomnia and with sleep duration, ii) the association of cumulative exposure to sexual harassment/assault with insomnia and sleep duration, and iii) to what extent nightmares could explain the association between sexual harassment and insomnia and sleep duration. For both genders, all forms of harassments with the exception of "indecent exposure" and "unwanted sexual photographs" for men were negatively associated with sleep duration, with the strongest associations being found for "rape" and "attempted rape". For both genders, the odds of insomnia increased as a function of cumulative harassment exposure. Similarly, a graded, negative association was found between cumulative harassment and sleep duration for both genders. Mediation analyses showed that 28% of the observed association between cumulative harassment and insomnia, and 15% of the association between cumulative harassment and sleep duration, was mediated by frequency of nightmares.

Alcohol-related problems among college and university students in Norway: extent of the problem.

Aims: The aim of the current study was to provide estimates of the distribution of alcohol-related problems in a large sample of college and university students. We also sought to examine trends in the distribution of alcohol-related problems from 2010 to 2018. Methods: Data stem from a recent national health survey from 2018 for higher education in Norway (the SHoT study) in which 50,054 full-time students (69.1% women; 30.9% men) aged 18-35 years participated. The Alcohol Use Disorders Identification Test (AUDIT) was used to assess potential alcohol-related problems. Data on demographic characteristics were also collected. Results: More than half of the male students (52.8%) and 4 out of 10 of the female students (40.1%) reported risky, harmful or dependent alcohol use. Compared to women, men had an increased risk of risky alcohol use (relative risk ratio (RRR) = 1.57), harmful alcohol use (RRR = 2.45) and dependent alcohol use (RRR = 2.73). Younger students had higher rates of risky and harmful alcohol use compared with older students, while rates of dependent alcohol use were similar across the age span. Several demographic variables were associated with alcohol use. The trend analyses revealed that the rates of risky, harmful and dependent alcohol use, as well as mean AUDIT scores, among the students have remained relatively stable over the past 8 years. Conclusions: Alcohol use remains an important health concern among Norwegian college and university students, and the present study confirms the high rates of alcohol-related problems, and the need to address the issue within this population.

Perceived consequences and worries among youth in Norway during the COVID-19 pandemic lockdown.

Aims: To examine perceived consequences for everyday life, learning outcomes, family relations, sleep problems and worries for infection, for friends and their future, among youth aged 12-19 years during weeks 7 to 9 of the COVID-19 lockdown in Norway. We examine variations by age, gender, socioeconomic status and country of birth. Methods: Youth within the municipality of Bergen were invited via SMS to participate in a 15-minute online survey. A total of 2997 (40%) youths participated. The mean age was 17 years (standard deviation 1.7). Results: Overall, 28% reported feeling somewhat to a lot impacted by schools closing, 63% reported learning less. In total, 62% reported improvement of everyday life. The youth's situation in their family was worse for 13%. Regarding sleep problems, 19% reported difficulties initiating and maintaining sleep, 12% had more nightmares, while 90% reported later bedtime and rise time. Seven per cent worried about getting infected, while 53% worried about infection among family members. A total of 19% worried that the outbreak would lead to a more difficult future, and 32%worried that friends were facing a difficult situation at home. Perceived consequences and worries related to the lockdown varied across sociodemographic groups. Conclusions: The perceived consequences and degree of worries varied by age, gender, socioeconomic status and to a certain degree country of birth. Girls, older youth, youth with lower socioeconomic status and with a migrant background from developing countries seemed to experience the lockdown as more difficult, and thereby possibly accentuating the need for services in these groups.

Locked and lonely? A longitudinal assessment of loneliness before and during the COVID-19 pandemic in Norway.

AIMS: There are concerns that lockdown measures taken during the current COVID-19 pandemic lead to a rise in loneliness, especially in vulnerable groups. We explore trends in loneliness before and during the pandemic and differences across population subgroups. METHODS: Data were collected via online questionnaires in June 2020 and four to eight months prior in two Norwegian counties (N=10,740; 54% women; age 19-92 years). Baseline data come from the Norwegian Counties Public Health Survey (participation rate 46%, of which 59% took part in a COVID-19 follow-up study). RESULTS: Overall loneliness was stable or falling during the lockdown. However, some subgroups, single individuals and older women, reported slightly increased loneliness during lockdown. Interestingly, individuals with low social support and high levels of psychological distress and loneliness before the pandemic experienced decreasing loneliness during the pandemic. CONCLUSIONS: Although data limitations preclude strong conclusions, our findings suggest that, overall, Norwegians seem to have managed the lockdown without alarming increases in loneliness. It is important to provide support and to continue investigating the psychological impact of the pandemic over time and across regions differentially affected by the pandemic.

Revisiting the continuum of resistance model in the digital age: a comparison of early and delayed respondents to the Norwegian counties public health survey.

BACKGROUND: The continuum of resistance model's premise is that delayed respondents to a survey are more similar to non-respondents than early respondents are. For decades, survey researchers have applied this model in attempts to evaluate and adjust for non-response bias. Despite a recent resurgence in the model's popularity, its value has only been assessed in one large online population health survey. METHODS: Respondents to the Norwegian Counties Public Health Survey in Hordaland, Norway, were divided into three groups: those who responded within 7 days of the initial email/SMS invitation (wave 1, n = 6950); those who responded after 8 to 14 days and 1 reminder (wave 2, n = 4950); and those who responded after 15 or more days and 2 reminders (wave 3, n = 4045). Logistic regression analyses were used to compare respondents' age, sex and educational level between waves, as well as the prevalence of poor general health, life dissatisfaction, mental distress, chronic health problems, weekly alcohol consumption, monthly binge drinking, daily smoking, physical activity, low social support and receipt of a disability pension. RESULTS: The overall response to the survey was 41.5%. Respondents in wave 1 were more likely to be older, female and more highly educated than those in waves 2 and 3. However, there were no substantial differences between waves for any health outcomes, with a maximal prevalence difference of 2.6% for weekly alcohol consumption (wave 1: 21.3%, wave 3: 18.7%). CONCLUSIONS: There appeared to be a mild continuum of resistance for demographic variables. However, this was not reflected in health and related outcomes, which were uniformly similar across waves. The continuum of resistance model is unlikely to be useful to adjust for nonresponse bias in large online surveys of population health.

Increasing similarities between young adults' smoking and snus use in Norway: a study of the trends and stages of smoking and snus epidemic from 2010 to 2018.

BACKGROUND: The prevalence of smoking has been decreasing in Norway for decades. In contrast, the prevalence of snus use has recently increased substantially, especially among females. While there is a clear social gradient in smoking, with a higher smoking prevalence among individuals with low socioeconomic status (SES), a possible social gradient in snus use has been less studied. The aim of the current study was to investigate the trends of smoking and snus use and to examine whether ongoing changes in snus use are similar to prior smoking epidemic development. METHODS: The study was based on the 2010 (n = 5836), 2014 (n = 13,319) and 2018 (n = 24,515) waves from a nation-wide, cross-sectional, health survey of higher education in Norway (the SHoT study). Variables on smoking, snus use, gender, age and SES were used. Chi-square tests and logistic regression analyses were used to test significance, and Mantel-Haenszel weights were used to test the trends in stratified cross-tabulations. RESULTS: Daily smoking decreased from 5.9 to 1.5% between 2010 and 2018, while daily snus use increased from 13.4 to 19.9%. Female snus use almost doubled, from 10.9 to 19.2%. Low SES was associated with both daily smoking and snus use across all three waves. Occasional smoking was also associated with low SES at all waves, but occasional snus use was only associated with low SES in 2010. There were no significant changes over time in either the association between occasional or daily smoking and SES or the association between occasional or daily snus use and SES. CONCLUSIONS: The overall smoking decrease indicated that the Norwegian smoking epidemic is in its latest stage. Steady male snus use, doubled female snus use and a clear social gradient in snus use all indicate that the snus epidemic in Norway has progressed. If this trend continues, a main implication is that snus prevalence will soon peak, first in males and then in females.
