Sweden's excess mortality in 2020-2022 and reporting in the media.

AIM: The aim was to scrutinize the report in March 2023 that Sweden's excess mortality was lowest in 2020-2022 compared with other European Union and Nordic countries, a report that received great national and international attention. STUDY DESIGN: Comparison of excess mortality in Sweden and Norway. METHODS: Excess mortality for 2020-2022 was calculated for Sweden and Norway, the country with per-capita excess mortality closest to Sweden's, compared with the average mortality for 2017-2019 in the respective country, following the definitions by Statistics Sweden reported in a daily newspaper. RESULTS: Excess mortality is a measure with low misclassification compared with other pandemic outcome measures. Following the definitions, total excess mortality for the years 2020-2022 was 11,897 individuals in Sweden and 6089 in Norway. However, the distributions of excess mortality across the 3 years strongly differed. In Sweden, 60% of excess mortality was observed in 2020, 8% in 2021 and 32% in 2022. In sharp contrast, 0% of excess mortality was observed in Norway in 2020, 20% in 2021 and 80% in 2022. If the relative distribution of excess mortality in Sweden had been the same as in Norway in 2020-2022, approximately 7000 individuals who died in 2020 would instead have died as excess mortality in 2022, saving approximately 14,000 person-years in Sweden. CONCLUSIONS: The report disregards residual confounding due to the broad definition of the period 2020-2022. Mass media should avoid one-sided reporting.

The social medicine specialty in southern Sweden.

AIMS: This article discusses the situation of the social medicine specialty in Skåne, southern Sweden with the aim of understanding the long-term trends of this medical specialty in Skåne and its relation to research in social medicine. RESULTS: In the 1950s to 1980s, there was a balance between clinical and preventive practice, and research. This balance was maintained in the 1980s to early 2000s as the medical specialty and the research moved 'upstream' in the chain of causality to psychosocial, socio-economic and contextual determinants of health. The increasingly 'upstream' character of the specialty and particularly its new position in the regional organisation since 2010 may have made it more vulnerable to general executive-level reorganisations. CONCLUSIONS: The specialty should maintain its 'upstream' focus but regain its proximal scope in prevention, epidemiology and health equity. It should regain its place in the health-care system organisation or alternatively become a state-based instead of regional specialty.

The COVID-19 pandemic and the timing of government response: A comparison of four Nordic countries March-June 2020.

OBJECTIVES: The aim is to compare Sweden, Denmark, Finland and Norway regarding government response to the COVID-19 pandemic in mid-March-June 2020 using the Oxford Government Response Tracker. STUDY DESIGN: Descriptive longitudinal ecological study. METHODS: Descriptive analysis of time series data. RESULTS: Sweden displayed a far lower response index in March. By late April indexes were similar. In May-June, response indexes were lower in Finland and Norway than in Sweden. The average response index in mid-March-June was similar in Sweden, Finland and Norway. CONCLUSIONS: The government response in the four countries indicates that timing of response was essential. Sweden's slow and weak initial government response in March-April was followed by less loosening of government response in May-June compared with, especially, Finland and Norway, which resulted in similar average government response in mid-March-June for the three countries. As a comparison, COVID-19 mortality per capita was 10 times higher in Sweden than in Finland and Norway, and five times higher than in Denmark during the same period.

Arts and culture engagement and mortality: A population-based prospective cohort study.

AIMS: The aim of this study was to investigate associations between having visited the theatre/cinema and an arts exhibition during the past year and all-cause, cardiovascular disease (CVD), cancer and other-cause mortality. METHODS: The 2008 public health postal survey in Scania, Sweden, was distributed to a stratified random sample of the adult population (18-80 years old). The participation rate was 54.1%, and 25,420 participants were included in the present study. The baseline 2008 survey data were linked to cause-of-death register data to create a prospective cohort with 8.3-year follow-up. Associations between visit to the theatre/cinema, visit to an arts exhibition and mortality were investigated in survival (Cox) regression models. RESULTS: Just over a quarter (26.5%) had visited both the theatre/cinema and an arts exhibition during the past year, 36.6% only the theatre/cinema, 4.9% only an arts exhibition and 32% neither of the two. Not visiting the theatre/cinema during the past year was associated with higher all-cause and CVD mortality. Not visiting an arts exhibition was associated with higher all-cause and other-cause mortality. The combination of having visited neither the theatre/cinema nor an arts exhibition during the past year was associated with higher all-cause, CVD and other-cause mortality. CONCLUSIONS: There is an association between attending arts and culture activities and a reduced risk of CVD and other-cause mortality but not cancer mortality, although model imperfections are possible.

Revisiting socio-economic inequalities in sedentary leisure time in Sweden: An intersectional analysis of individual heterogeneity and discriminatory accuracy (AIHDA).

AIMS: Swedish public health reports have repeatedly provided information about socio-economic inequalities in sedentary leisure time, despite that, in the interest of health equity, physical activity should be equally distributed in the population. Such public health reports, however, neither consider the intersection of multiple socio-demographic factors nor the individual heterogeneity around group averages. Drawing on intersectionality theory, this study aimed to revisit previous findings on sedentary leisure time from Swedish public health surveys and demonstrate how the analysis of individual heterogeneity and discriminatory accuracy (AIHDA) can be used for analysing complex health inequalities. METHODS: Using data from Swedish national public health surveys (2004-2015), we applied the AIHDA to define 72 intersectional groups by categories of age, gender, educational achievement, migration status and household composition. We then calculated (a) the absolute and relative risk of sedentary leisure time and (b) the discriminatory accuracy (DA) of the intersectional grouping. RESULTS: The average risk of sedentary leisure time ranged from 5.8% among native-born, highly educated, young women living alone to 41.0% among immigrated young men, living alone, with low education. The risk was higher in strata comprising immigrated people with low education and lower in strata including native-born, highly educated people. However, the DA of the grouping was poor, indicating a substantial overlap of individual risk between groups. CONCLUSIONS: Using the AIHDA and drawing on intersectionality, this study provides an improved mapping of the socio-economic distribution of sedentary leisure time in Sweden, with the poor DA suggesting universal rather than targeted physical activity interventions.

Is kidney biopsy necessary in children with idiopathic nephrotic syndrome?

AIM: To investigate the need, in the Northern European setting, to perform kidney biopsy in children with steroid-sensitive nephrotic syndrome. METHODS: In this retrospective study 124 individuals aged 1-18 years with idiopathic nephrotic syndrome, followed in the paediatric hospitals in southern Sweden from 1999 to 2018, were included. RESULTS: There was a median follow-up time of 6.5 (0.2-16.8) years. The majority (92%) of children were steroid-sensitive and of them, 60.5% were frequently relapsing or steroid-dependent. Microscopic haematuria was found at onset in 81.1% and hypertension in 8.7%. At least one kidney biopsy was performed in 93 (75%). The most common indication was a steroid-dependent or relapsing course (58.4%). One of 79 steroid-sensitive children had another histological diagnosis than minimal change nephropathy 1.3%, 95% confidence interval (0.002, 0.068). Bleeding occurred after eight biopsies (6.6%). Twenty individuals (30.7%) were transferred to adult units, 18 still on immunosuppression. CONCLUSION: We have in our cohort of unselected children with idiopathic nephrotic syndrome confirmed that a kidney biopsy rarely gives important medical information in steroid-sensitive children without any other complicating factor and that the liberal policy of kidney biopsy in the Nordic countries safely can be changed.

Arts and culture engagement for health: a Danish population-based study.

OBJECTIVES: Global health challenges are complex and new approaches are pivotal. Engagement in arts and cultural activities is commonplace across different cultures, and research shows associations with benefits for health and wellbeing. Using the arts for health promotion and prevention of illness has increased worldwide. STUDY DESIGN: A population-based study. METHODS: Data were obtained from the Danish Health and Wellbeing Survey in 2019. A self-administered questionnaire was sent to 14,000 randomly selected adults (aged ≥15 years). The questionnaire included items on self-rated health and frequency of participation in various cultural activities (concerts or musical events; participation in a choir, band, or orchestra; theatre show or other performing arts; cinema; art museum or exhibition; library). A cultural participation index was calculated based on the six questions on cultural activities. Logistic regression models were fitted to examine the associations between the index and good self-rated health, adjusting for relevant covariates. RESULTS: In total, 6629 individuals completed the questionnaire (47.4%). The most frequent activity, used at least once a month, was visiting a library. A strong association between the cultural participation index and self-reported health was observed. A one-point-higher index score was associated with a 10% higher likelihood of having good self-reported health (adjusted odds ratio: 1.10; 95% confidence interval: 1.08-1.12). CONCLUSIONS: This study supports the understanding that engagement in arts and cultural activities is beneficial for self-rated good health. Individuals with higher frequency of arts and culture engagement were more likely to report good health than those with lower engagement.

Increased prevalence of human papillomavirus in fresh tissue from penile cancers compared to non-malignant penile samples: a case-control study.

BACKGROUND: HPV has been detected in approximately 50% of invasive penile cancers but with a large span between 24 and 89%, most likely due to different types of tumors and various methods for HPV analysis. Most studies of HPV in penile cancer have been performed using paraffin-embedded tissue, argued to be at risk for contaminated HPV analysis. Viral activity of HPV, by the use of HPV mRNA expression is well studied in cervical cancer, but seldom studied in penile cancer. The aim was to determine prevalence of HPV types in fresh tissue of penile cancers compared to non-malignant age-matched penile controls. Additional aims were to analyze the viral expression and copy numbers of HPV16-positive tumors and 10 mm adjacent to the tumor. METHODS: Fresh tissue from penile cancer cases was biopsied inside the tumor and 10 mm outside the tumor. Controls were males circumcised for non-malignant reasons, biopsied at surgery. PCR and Luminex assays were used for identification of HPV types. HPV16-positive samples were investigated for copy numbers and expression of HPV16-mRNA. RESULTS: Among tumors (n = 135) and age-matched controls (n = 105), HPV was detected in 38.5% (52/135) and 11.4% (12/105), respectively (p < 0.001), adjusted odds ratio 12.8 (95% confidence interval 4.9-33.6). High-risk HPV types were found in 35.6% (48/135) of tumors and 4.8% (5/105) of controls (p < 0.001). Among tumors and controls, HPV16 was present in 27.4% (37/135) and 1% (1/105), respectively (p < 0.001). Among HPV16-positive penile cancers, mean HPV16 viral copy/cell was 74.4 (range 0.00003-725.4) in the tumor and 1.6 (range 0.001-14.4) 10 mm adjacent from the tumor. HPV16-mRNA analysis of the tumors and 10 mm adjacent from the tumors demonstrated viral activity in 86.5% (32/37) and 21.7% (5/23), respectively. CONCLUSIONS: The prevalence of HPV was significantly higher in penile cancer (38.5%) than among age-matched non-malignant penile samples (11.4%). HPV16 predominates (27.4%) in penile tumors. HPV16 expression was more common in penile cancer than in adjacent healthy tissue, strongly suggesting an etiological role for HPV16 in the development of penile cancer.

Health locus of control and all-cause, cardiovascular, cancer and other cause mortality: A population-based prospective cohort study in southern Sweden.

The aim was to investigate associations between health locus of control (HLC) and all-cause, cardiovascular (CVD), cancer and other cause mortality. A public health postal questionnaire was distributed in the autumn of 2008 to a stratified random sample of the 18-80 year old adult population in Scania in southernmost Sweden. The participation rate was 54.1%, and 25,517 participants were included in the present study. Baseline 2008 survey data was linked to cause of death register data to create a prospective cohort with 8.3-year follow-up. Associations between health locus of control and mortality were investigated in survival (Cox) regression models. Prevalence of internal HLC was 69.0% and external HLC 31.0% among women. Internal HLC was 67.6% and external HLC 32.4% among men. In the models with women and men combined, external HLC had significantly higher all-cause, CVD, cancer and other cause mortality even after adjustments for sociodemographic factors and chronic disease at baseline, but after the introduction of health-related behaviors, external HLC only displayed higher cancer mortality compared to internal HLC. External HLC displayed higher all-cause, cancer and other cause mortality for men in the final model adjusted for health-related behaviors, but not for women. Other pathways than health-related behaviors may exist for the association between external HLC and cancer mortality, particularly among men.

Psychosocial stress and social capital pathways and health: Perspectives from Lund University, Malmö.

AIMS: The aim of this Commentary is to outline a few steps of the process by which psychosocial stress and later social capital have been investigated as health determinants at Lund University, Malmö since the 1980s. References to the international literature and literature from Malmö from the mid-1980s and onwards will be used. RESULTS: The development of research on psychosocial factors and social capital has followed international progress, with a complementary focus on social capital from the late 1990s onwards. Social participation, entailing a number of social activities, seems to be both the common connection between psychosocial stress theory and social capital and the common denominator between cohesion and structural/network approaches to social capital and health. CONCLUSIONS: The impact of this research area has been considerable in Sweden. Both psychosocial factors and social capital have been acknowledged as health determinants in national Swedish health policy, although a setback may be discerned in recent years.

Parental separation/divorce in childhood and tobacco smoking in adulthood: A population-based study.

Aims: The aim was to investigate associations between the experience of parental separation/divorce in childhood and tobacco smoking in adulthood, adjusting for economic stress in childhood and adulthood and psychological health (General Health Questionnaire GHQ12). Methods: The 2012 public-health survey in Skåne, southern Sweden, is a cross-sectional postal questionnaire population-based study with 28,029 participants aged 18-80 (51.7% response rate). Associations between parental separation/divorce in childhood and tobacco smoking were investigated in multiple logistic regression models, with adjustments for economic stress in childhood and adulthood and psychological health. Results: A 17.6% weighted prevalence of men and 17.1% of women reported tobacco smoking. Significantly higher odds ratios of tobacco smoking were observed for men who had experienced parental separation/divorce in childhood at ages 0-4, 5-9 and 15-18 years and for women with this experience in childhood at ages 0-4, 5-9, 10-14 and 15-18 years, even after inclusion of economic stress in childhood in the final multiple models. No effect modification was observed for parental separation and psychological health and for parental separation and economic stress in childhood with regard to smoking. Conclusions: Experience of parental separation/divorce in childhood was significantly associated with tobacco smoking in adulthood for both sexes. There seems to be no specific critical period.

Unmet health-care needs and mortality: A prospective cohort study from southern Sweden.

Aims: Research on the effect of unmet health-care needs on mortality at follow-up is scarce. This study investigated whether unmet health-care needs in 2008 were associated with a higher risk of mortality during a five-year follow-up period in a population in southern Sweden, and whether the association was stronger for particular subgroups of cause of death. Methods: The 2008 public-health survey in Skåne was used as baseline. The survey included variables such as unmet health-care needs, risk behaviours and social and socio-economic variables, and had 28,198 respondents aged 18-80 years. The study was longitudinal. Mortality data for the period 27 August 2008 (start of the survey) to 31 December 2013 were provided by the National Board on Health and Welfare. Analyses were run using Cox proportional hazard models. Mortality was analysed as the total and in subgroups: cardiovascular disease (CVD), cancer and other causes. Results: In the time period studied, 946 (3.4%) people had died. Unmet health-care needs increased the hazard ratios (HRs) of total mortality after adjusting for age, particularly for people aged 65-80 years (HR=1.53; confidence interval 1.24-1.88). Unmet health-care needs were associated with death due to cancer and other causes but not with CVD. Adjusting for self-rated health attenuated the HRs. For the age group 18-64 years, there was no significant association between unmet health-care needs and mortality. Conclusions: Having unmet health-care needs at baseline was significantly associated with increased mortality for all causes, except CVD, in the following five year-period, particularly for people aged 65-80 years.

Associations between self-injury and involvement in cyberbullying among mentally distressed adolescents in Scania, Sweden.

AIMS: To investigate associations between self-injury and involvement in cyberbullying as a bully, victim or bully-victim among mentally distressed adolescents. METHODS: Data from the public health survey of children and adolescents in Scania, Sweden 2016 were used. A questionnaire was answered anonymously in school by 9143 students in 9th grade compulsory school (response rate 77%) and 7949 students in 2nd grade of upper secondary school (response rate 73%). Students with past year (broadly defined) mental distress at least 2 weeks in a row (33% of boys and 63% of girls) were asked if they had performed self-injury (i.e. cut, superficially cut or otherwise injured themselves) past year, and those with data on self-injury and cyberbullying were included in the present study ( n=6841). Associations between self-injury and cyberbullying were investigated by multiadjusted logistic regression analysis. RESULTS: Among mentally distressed students, self-injury was reported by 11.7% of boys and 25.9% of girls. Age-adjusted analysis showed increasingly higher odds of self-injury among cyberbullies, cybervictims and cyberbully-victims, using non-involved as reference group (OR boys: 1.8, 2.3, 3.0; girls: 2.1, 3.2, 4.8). Associations weakened after adjustment for several potential confounders but remained significant for all cyberbullying groups except male cyberbullies, among whom significance was lost after adjustment for smoking, alcohol and narcotics. CONCLUSIONS: Peer victimization in cyber space is associated with self-injury, especially among victims and bully-victims. Decreasing peer victimization is a priority, and school and health professionals need to be aware of the associations between cyberbullying and self-injury among mentally distressed adolescents.

Volumetric measurement of dentoalveolar defects by means of intraoral 3D scanner and gravimetric model.

The aim of this study was to evaluate the accuracy in volumetric measurements obtained on an experimental model using an intraoral scanner and a gravimetric method. Three identical partial dentate maxillary acrylic models with three fabricated alveolar defects, in anterior and posterior regions, were scanned using an intraoral scanner (20 scans/defects). The defects differed in terms of size and distance of neighbouring teeth. As references, replicas of each defect were created using a dimensional stable silicone impression material. After measuring the mass of each replica, the volume was calculated by dividing the mass of each replica by the density of the impression material. The defects had a volume, according to the gravimetric method, ranging from 40.5 to 143.7 mm3. The scans were imported to metrology software for analyses. Accuracy was determined in terms of trueness and precision. The mean trueness for all defect types was 0.168 mm3 (SD 0.691, range 2.82). There was no statistical significant difference between the mean trueness for all defects measured (p = 0.910). The mean precision for all defect types was 0.147 mm3 (SD 0.524, range 2.86). There were no statistical significant differences between the dental models in regard to mean precision (p = 0.401), however, there were statistical significant differences between defects in position 1 and 2 (p = 0.002) and 1 and 3 (p = 0.001). Based on the findings of this study, the intraoral scanner utilized in the current study presented an acceptable level of accuracy when measuring volume of defects.

Self-rated health and social capital in Iraqi immigrants to Sweden: The MEDIM population-based study.

OBJECTIVES: Poor self-rated health is an estimator of quality of life and a predictor of mortality seldom studied in immigrant populations. This work aimed to study self-rated health in relation to social capital, socioeconomic status, lifestyle and comorbidity in immigrants from Iraq - one of the largest non-European immigrant group in Sweden today - and to compare it with the self-rated health of native Swedes. DESIGN: The study was a cross-sectional population-based study conducted from 2010 to 2012 among citizens of Malmö, Sweden, aged 30-65 years and born in Iraq or Sweden. All participants underwent a health examination and answered questionnaires on self-rated health, social capital, comorbidity, lifestyle and socioeconomic status. RESULTS: In total, 1348 Iraqis and 677 Swedes participated. Poor self-rated health was identified in 43.9% of Iraqis and 21.9% of native Swedes ( p<0.001), with the highest prevalence (55.5%) among Iraqi women. Low social capital was highly prevalent in the immigrants. Female gender showed higher odds of poor self-rated health in Iraqis than in Swedes (OR 1.8, 95% CI 1.4-2.5, pinteraction=0.024), independent of other risk factors connected to social capital, socioeconomic status, lifestyle or comorbidity. CONCLUSIONS: Although public health initiatives promoting social capital, socioeconomic status and comorbidity in immigrants are crucial, the excess risk of poor self-rated health in Iraqi women is not fully attributed to known risk factors for self-rated health, but remains to be further explored.

Differences in unmet healthcare needs between public and private primary care providers: A population-based study.

AIMS: To investigate if any differences in unmet healthcare needs between persons registered at public and private primary care providers exist in Skåne (southernmost Sweden). METHODS: The 2012 public health survey in Skåne was conducted with a postal questionnaire and included 28,029 respondents aged between 18 and 80 years. The study was cross-sectional. If the responder in the last three months had perceived oneself to be in need of medical care by a physician but did not seek it, this was used as a measure of unmet healthcare needs. Differences in unmet healthcare needs in relation to the primary care provider were investigated while adjusting for socioeconomic status and self-rated health in a logistic regression. RESULTS: Differences in unmet healthcare needs were small and non-significant when comparing public and private healthcare providers. Non-manual workers were to a somewhat higher extent using private providers while manual workers showed a reverse pattern. Unmet healthcare needs had decreased slightly since 2008, but so had the response rate. CONCLUSIONS: With the current primary care system, no significant differences in unmet healthcare needs seem to exist when comparing public and private providers. It is likely that the providers are similar in their organizational setup, accessibility and doctor-patient continuity. Still more studies need to be done, preferably in a way so that uncertainty about what type of primary care provider the respondent is listed at can be avoided and perhaps using a longer time interval for unmet needs so that more subjects could be included.

Subjective health complaints and exposure to peer victimization among disabled and non-disabled adolescents: A population-based study in Sweden.

AIMS: To investigate subjective health complaints (SHCs) (psychological and somatic, respectively) among disabled and non-disabled adolescents, focusing on the impact of traditional bullying and cyber harassment, and furthermore to report psychological and somatic SHCs across different types of disability. METHODS: Data from the public health survey of children and adolescents in Scania, Sweden, 2012 was used. A questionnaire was answered anonymously in school by 9791 students in the 9th grade (response rate 83%), and 7533 of these with valid answers on key questions were included in this study. Associations with daily SHCs were investigated by multi-adjusted logistic regression analyses. RESULTS: Any disability was reported by 24.1% of boys and 22.0% of girls. Disabled students were more exposed to cyber harassment (boys: 20.0%; girls: 28.2%) than non-disabled peers (boys: 11.8%; girls: 18.1%). Exposure to traditional bullying showed the same pattern but with a lower prevalence. Disabled students had around doubled odds of both daily psychological SHCs and daily somatic SHCs in the fully adjusted models. In general, the odds increased with exposure to cyber harassment or traditional bullying and the highest odds were seen among disabled students exposed to both cyber harassment and traditional bullying. Students with ADHD/ADD had the highest odds of daily psychological SHCs as well as exposure to traditional bullying across six disability types. CONCLUSIONS: Disabled adolescents report poorer health and are more exposed to both traditional bullying and cyber harassment. This public health issue needs more attention in schools and in society in general.

Changes in Social Capital and Cigarette Smoking Behavior Over Time: A Population-Based Panel Study of Temporal Relationships.

INTRODUCTION: Identifying factors that influence individuals' smoking behavior remains a huge public health concern. This study aimed to investigate changes in individuals' cigarette smoking while considering well-known smoking determinants, including social capital, its presence being postulated to reduce smoking. METHODS: From British Household Panel Survey data, two baseline smoking cohorts were created ("smoking" and "not smoking"). The same individuals from this nationally representative sample (NT = 8114, aged 16-91 years) were interviewed on four occasions between years 2000 and 2007 to investigate changes in cigarette smoking behavior. Logistic regression models with random effects compensated for within-individual behavior over time. Temporal pathways were investigated by lagging independent variables (t - 1) in relation to our cigarette-use outcome at time (t). RESULTS: Active social participation at (t - 1) was positively associated with smoking cessation at (t) (odds ratio [OR] = 1.39; 95% confidence interval [CI] [1.07-1.82]). Separating from one's spouse at (t - 1) increased risk for smoking relapse/initiation at (t) (OR = 6.63; 95% CI [1.70-28.89]). Conversely, being married protected against smoking cigarettes (OR = 1.87; 95% CI [1.15-3.04]). These associations held in our robustness checks. CONCLUSIONS: Initial marital breakdown predicted a high risk of smoking relapse/initiation. The timing of this life event provides a critical window where adverse smoking behavior might occur. Conversely, the positive effects of active social participation on cigarette cessation remained consistent, its absence further predicting smoking relapse/initiation. Robustness of results confirms the important role that active participation has on cigarette smoking behavior. Group smoking cessation interventions could harness participatory elements to better achieve their goals. IMPLICATIONS: By investigating temporal relationships between well-known smoking determinants and cigarette smoking outcomes, we identified that being "separated" (not "divorced") at time (t) predicted a higher risk of smoking relapse/initiation at (t). Tailored health messages could be employed to highlight the increased risk of cigarette smoking relapse/initiation during this stressful life event. Conversely, active social participation (a common social capital proxy) consistently predicted smoking cessation over time. Future group smoking cessation interventions could be designed explicitly to harness participatory elements to better achieve their goals.

Age at smoking initiation and self-rated health among second grade high school boys and girls in Scania, Sweden, a cross-sectional study.

BACKGROUND: Smoking is usually initiated early in life and most adult regular smokers have started smoking before 18 years of age. A younger age at smoking initiation is associated with risk taking behaviours and worse health outcomes regarding psychological and somatic conditions, suggested to be caused by exposure during critical developmental periods. The present study aims to investigate self-rated health among second grade high school boys and girls related to age at smoking initiation (<14 years of age and ≥ 14 years of age) among current and former smokers, compared to never smokers. METHODS: Data was derived from the Scania public health survey among children and adolescents in 2012. The study was cross-sectional with retrospective information about first time cigarette smoking experiences among 3245 boys and 3434 girls in second grade of high school. Self-rated health was assessed with the question "How do you rate your general health". Associations of age at smoking initiation, current smoking status and poor self-rated health were investigated with logistic regression models. RESULTS: Crude odds ratios of poor self-rated health were increased for all smoking groups compared to never smokers. Former smoking boys and currently smoking girls with early smoking initiation had the highest odds ratios of poor self-rated health, with odds ratios (OR) 2.4 (95 % confidence interval (CI): 1.5-3.7) and OR 2.9 (95 % CI: 2.3-3.6), respectively. After adjustments for sociodemographic factors, health-related behaviours, psychosocial factors, weight and functional disabilities, the results were attenuated, but remained statistically significant regarding former and current smoking boys with early smoking initiation, OR 2.0 (95 % CI: 1.1-3.7) and OR 1.7 (95 % CI: 1.1-2.4) and for current smoking girls with early and later smoking initiation, OR 2.1 (95 % CI: 1.5-2.8) and OR 1.5 (95 % CI: 1.1-2.0). CONCLUSION: Boys and girls in second grade of high school with early smoking initiation reported poorer self-rated health than later initiators and never smokers. Poorer self-rated health persisted also after smoking cessation among early initiating boys. Further studies are needed to understand the adverse health effects associated with timing of smoking initiation.

Subjective health complaints in adolescent victims of cyber harassment: moderation through support from parents/friends - a Swedish population-based study.

BACKGROUND: Victimization in cyberspace has emerged as a new public health issue among the young. The main purpose of this study was to analyze associations between cyber victimization defined as cyber harassment (CH) (a somewhat broader concept than cyberbullying) and subjective health complaints (SHC), to study whether these associations were modified by parental/friend support (measured as communication), and to explore the influence of traditional bullying victimization (TBV) on the association between CH and SHC. METHODS: The study population consisted of 8544 students in 9th grade (around 15 years old) who participated in the 2012 Scania public health survey of children and adolescents. The survey was a cross-sectional total-population study conducted in school, with a response rate of 83 %. Main and interaction (stress-buffering) effects of social support on the relationship between CH and SCH were investigated by hierarchical multiple linear regression analyses, adjusted for potential confounders, including TBV. RESULTS: The past-year prevalence of CH (once or several times) was 14 % among boys and 20 % among girls. Having been cyber harassed once or several times during the past year was associated with higher levels of SHC, controlling for age, parental occupation, parental origin, daily smoking, intense alcohol consumption, and disability. Among both boys and girls, the associations were stronger for CH occurring several times than for CH occurring only once. Main effects of parental/friend support were seen for both boys and girls, while stress-buffering effects were indicated for boys only. Additional analysis further adjusting for TBV did not change the associations substantially, indicating that CH has an effect of its own on SHC. CONCLUSION: Intervention programs aimed at improving the quality of peer and family relationships among children and adolescents might reduce the incidence of both cyber harassment and traditional bullying and lower the prevalence of psychosomatic complaints.
