Socioeconomic inequalities in sexual victimisation in a nationally representative sample of the Swedish population.

AIMS: Sexual victimisation is a key public health concern because of its physical, psychological and social consequences. Nationally representative studies exploring sexual victimisation and re-victimisation are still scarce. The aim of the current study was to explore associations of sexual victimisation with sociodemographic factors including sexual orientation in Sweden. METHODS: We used Swedish data from a national population survey linked to nationwide registers. The sample consisted of 3349 individuals aged 30-44 years, (2021 women and 1328 men). With a latent class analysis we identified groups of individuals with distinctly different experiences of sexual victimisation. Multinomial logistic regression was used to explore how common characteristics could explain latent class membership classes. RESULTS: Experiences of sexual victimisation were common: 48% of women and 13% of men had experienced sexual harassment, 47% of women and 12% of women sexual assault, 11% of women and 1% of men attempted intercourse and 8% of women and 1% of men rape. Among women four groups were identified who had distinctly different experiences of exposure to sexual victimisation such as low victimisation, sexually harassed and assaulted several times, highly sexually victimised with low re-victimisation and finally high victimisation. Both women and men who were highly sexually victimised had to a higher extent a non-heterosexual sexual identity. CONCLUSIONS: Non-heterosexual orientation is a robust indicator of a high level of sexual victimisation as well as re-victimisation among both male and female adults.

Having a child without wanting to? Estimates and contributing factors from a population-based survey in Sweden.

AIMS: The aims of the current study were to identify the prevalence of unwanted childbirth (UC), to explore the association with sociodemographic factors and to identify possible contributing factors such as psychosomatic health, contraceptive use, experiences of induced abortion and sexual violence. METHODS: We used Swedish data from the randomised population-based study SRHR2017 on sexual and reproductive health and rights (SRHR), based on self-administered surveys, linked to nationwide registers. The national sample consisted of 14,537 women and men aged between 16 and 84 years. With logistic regression, we examined differences in self-reported experience of UC, stratified by sex, in relation to socio-economic factors, as well as several possible contributing factors. RESULTS: Despite advances in SRHR and fertility control, 6% of women and men in Sweden reported UC. This experience tends to be unevenly distributed in the population according to age, country of birth and, to some extent, income and educational attainment. Previous experience of induced abortion, sexual violence and threat from a partner were significantly associated with UC, whereas self-reported good health was protective. CONCLUSIONS: Mechanisms behind unintended, unplanned, unwanted or mistimed pregnancies are complex. Current results focus on the role of individual factors and personal experiences. In addition, in line with previous understanding, there is a need for adopting a broader socio-ecological perspective on fertility intentions.

Are Men Who Buy Sex Different from Men Who Do Not?: Exploring Sex Life Characteristics Based on a Randomized Population Survey in Sweden.

The buying and selling of sex is a topic of frequent discussion and a relevant public health issue. Studies of sex workers are available, while studies addressing the demand side of sex are scarce, especially based on robust population data. The current study provides national estimates of the prevalence of and factors associated with having paid for sex among men in Sweden. We used a randomized population-based survey on sexual and reproductive health and rights among ages 16-84 years, linked to nationwide registers. The sample consisted of 6048 men. With a logistic regression, we analyzed what sex life factors were associated with ever having paid for or given other types of compensation for sex. A total of 9.5% of male respondents reported ever having paid for sex. An increased probability of having paid for sex was identified in men who were dissatisfied with their sex life (aOR: 1.72; 95% CI: 1.34-2.22), men reporting having had less sex than they would have liked to (aOR: 2.78; 95% CI: 2.12-3.66), men who had ever looked for or met sex partners online (aOR: 5.07; 95% CI: 3.97-6.46), as well as frequent pornography users (aOR: 3.02; 95% CI: 2.28-3.98) Associations remained statistically significant after adjustment for age, income, and educational attainment. Sex life characteristics such as poor sex life satisfaction, high online sex activity, and frequent pornography use are strongly associated with sex purchase. These findings can help guide and support counselling and prevention activities targeting sex buyers.

Psychological Distress, Suicidal Ideation, and Suicide Attempt Among Lesbian, Gay, and Bisexual Immigrants: Population-Based Findings from the Stockholm Public Health Cohort.

In a large, population-based sample in Sweden, we sought to examine mental health disparities between lesbian, gay and bisexual (LGB) and heterosexual individuals with different immigration statuses. We conducted a population-based study including 1799 LGB and 69,324 heterosexual individuals, recruited in 2010 and 2014 as part of the Stockholm Public Health Cohort. Data were obtained from self-administered surveys that were linked to nationwide registers. We examined associations between mental health outcomes (i.e., psychological distress, suicidal ideation, and suicide attempt) and sexual orientation (LGB versus heterosexual), immigration status (immigrant versus Nordic-born), and their interaction. Sex-stratified weighted multivariable logistic regression analyses were used to calculate adjusted odds ratios with 95% confidence intervals. LGB individuals demonstrated substantially elevated odds of all mental health outcomes compared to heterosexuals; immigrants reported moderately elevated odds of psychological distress and suicide attempt, but not suicidal ideation, compared to Nordic-born individuals. Interaction terms between sexual orientation and immigration status were significant at p < 0.05 for psychological distress for both sexes and for suicidal ideation and attempt among women. Unexpectedly, models probing interactions generally demonstrated that Nordic-born LGB individuals demonstrated greater risk of psychological distress, suicidal ideation, and suicide attempt than did immigrant LGB individuals, especially among women. Supplemental analyses showed that Nordic-born bisexual women demonstrated the highest risk of all studied outcomes. Being LGB in Sweden is generally a stronger risk factor for poor mental health among Nordic-born than immigrant populations. These findings call for future intersectionality-focused research to delineate the unique cultural, social, and psychological factors associated with mental health and resilience among LGB immigrants.

Sexual Orientation-Related Differences in Sexual Satisfaction and Sexual Problems-A Population-Based Study in Sweden.

INTRODUCTION: Human sexuality is a natural and important part of peoples' life and well-being. The underlying interactions affecting sexual satisfaction are complex, and sexual orientation differences partly remain to be identified as well as explained. AIM: Our aim was to investigate sexual orientation-related differences in sexual satisfaction and sexual dissatisfaction and differences in sexual function and sexual-related problems. METHODS: We used Swedish data from SRHR2017 (sexual and reproductive health and rights), based on self-administered surveys, linked to nationwide registers. The national sample consisted of 14,537 women and men aged 16-84 years. With logistic regression, we examined sexual orientation-related differences in self-reported sexual satisfaction and sexual dissatisfaction, stratified by sex. MAIN OUTCOME MEASURES: The main outcome measures of this study are odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: Bisexual women were more dissatisfied with their sex life, as compared with heterosexual women (OR: 1.8; 95% CI: 1.3-2.6), as were bisexual men compared with heterosexual men (OR: 2.7; 95% CI: 1.7-4.4). A bisexual or lesbian identity was a robust risk factor for premature orgasm (OR: 2.1; 95% CI: 1.1-3.9 and OR: 8.0; 95% CI: 3.2-20.0, respectively). Lesbian women seemed to have lower risk for many sexual-related problems (however not significant). Gay men lacked arousal (OR: 3.3; 95% CI: 1.6-6.9), had no orgasm (OR: 2.6; 95% CI: 1.4-4.7), and were at lower risk of experiencing premature ejaculation (OR: 0.4; 95% CI: 0.2-0.9), as compared with heterosexual men. CONCLUSION: Our findings contribute to the sparse evidence of some sexual orientation differences in sexual satisfaction and sexual dysfunctions. Especially bisexual women and men appear to experience less sexual satisfaction in relation to heterosexual and homosexual women and men. Björkenstam C, Mannheimer L, Löfström M, et al.

Meeting Sexual Partners Online and Associations With Sexual Risk Behaviors in the Swedish Population.

BACKGROUND: Online arenas may facilitate sexual encounters. However, to what extent finding sexual partners online is associated with sexual risk behavior and sexual health outcomes is still not fully explored. METHODS: A stratified randomized population based study on sexual and reproductive health and rights of 50,000 Swedes was conducted in 2017. The final sample consisted of 14,537 women and men aged 16-84 years. We identified sexual health factors associated with finding sexual partners online and estimated prevalences thereof. RESULTS: Having used the internet to meet sexual partners was reported by 11% (95% confidence interval: 10.1-12.3) of men and 7% (95% confidence interval: 6.0-7.4) of women and was most common among men aged 30-44 years (13.7%). After adjustment, those reporting a non-heterosexual identity were most likely to meet sexual partners online. Meeting sexual partners online was also associated with reporting several sexual risk behaviors: condomless sex with temporary partner during the past 12 months, adjusted odds ratio (AOR): 5.1 (3.8-6.8) for women and AOR: 6.0 (4.5-7.9) for men, and having had a test for sexually transmitted infections (STIs) generated a 4-fold AOR for both sexes, STI diagnosis showed a 2-fold AOR, ever having paid or given other compensation for sex AOR: 4.8 (2.7-8.8) for women and AOR: 4.2 (2.9-6.1) for men as well as ever having received money or other compensation for sex AOR: 4.0 (1.3-11.9) for women and AOR: 6.0 (2.4-15.1) for men. CLINICAL TRANSLATION: Meeting sexual partners online was associated with sexual risk behaviors, which is of importance in tailoring sexual health interventions and STI/HIV-control activities. STRENGTHS AND LIMITATIONS: Few studies of online sexual behaviors are based on population-based surveys of the general population with results stratified by sexual identity. However, the use of lifetime prevalence of ever having used the internet, smartphone, or app to meet sexual partners has limitations. CONCLUSION: Meeting sexual partners online was associated with sexual risk behaviors in a randomized sample of the Swedish population, which is of importance to tailoring sexual health interventions.

Sickness absence and disability pension in relation to first childbirth and in nulliparous women according to occupational groups: a cohort study of 492,504 women in Sweden.

BACKGROUND: Childbirth has been suggested to increase sickness absence (SA) and disability pension (DP). This may vary by occupation; however, knowledge in this field remains limited. We explored SA and DP in the years before and after childbirth among women in four occupational groups and those without occupation. METHODS: We studied nulliparous women aged 18-39 years, living in Sweden on December 31, 2004 (n = 492,504). Women were categorized into five skill-level based occupational groups and three childbirth groups; no childbirths within 3 years (B0), first childbirth in 2005 with no childbirth within 3 years (B1), and first childbirth in 2005 with at least one more birth within 3 years (B1+). We compared crude and standardized annual mean SA (in spells> 14 days) and DP net days in the 3 years before and 3 years after first childbirth date. RESULTS: Women in the highest skill level occupations and managers, had less mean SA/DP days during most study years than women in the lowest skill level occupations group. In B1 and B1+, absolute differences in mean SA/DP, particularly in SA, among occupational groups were highest during the year before childbirth. DP was most common in B0, regardless of group and year. CONCLUSIONS: We found that women's mean SA/DP days before and after first childbirth was higher with decreasing skill-level of the occupational group and these differences were most pronounced in the year before childbirth. DP was most common among women not giving birth, regardless of occupational group.

Parental Sexual Orientation and Children's Psychological Well-Being: 2013-2015 National Health Interview Survey.

Debate persists about whether parental sexual orientation affects children's well-being. This study utilized information from the 2013 to 2015 U.S., population-based National Health Interview Survey to examine associations between parental sexual orientation and children's well-being. Parents reported their children's (aged 4-17 years old, N = 21,103) emotional and mental health difficulties using the short form Strengths and Difficulties Questionnaire (SDQ). Children of bisexual parents had higher SDQ scores than children of heterosexual parents. Adjusting for parental psychological distress (a minority stress indicator) eliminated this difference. Children of lesbian and gay parents did not differ from children of heterosexual parents in emotional and mental health difficulties, yet, the results among children of bisexual parents warrant more research examining the impact of minority stress on families.

Anxiety and Depression Among Sexual Minority Women and Men in Sweden: Is the Risk Equally Spread Within the Sexual Minority Population?

INTRODUCTION: Sexual minority individuals have a higher risk of anxiety and depression compared with heterosexuals. However, whether the higher risk is spread equally across the sexual minority population is not clear. AIM: To investigate the association between sexual orientation and self-reported current anxiety and a history of diagnosis of depression, paying particular attention to possible subgroup differences in risks within the sexual minority population, stratified by sex and to examine participants' history of medical care for anxiety disorders and depression. METHODS: We conducted a population-based study of 874 lesbians and gays, 841 bisexuals, and 67,980 heterosexuals recruited in 2010 in Stockholm County. Data were obtained from self-administered surveys that were linked to nationwide registers. MAIN OUTCOME MEASURES: By using logistic regression, we compared risks of current anxiety, histories of diagnosed depression, and register-based medical care for anxiety and/or depression in lesbian and gay, bisexual, and heterosexual individuals. RESULTS: Bisexual women and gay men were more likely to report anxiety compared with their heterosexual peers. Bisexual individuals and gay men also were more likely to report a past diagnosis of depression. All sexual minority groups had an increased risk of having used medical care for anxiety and depression compared with heterosexuals, with bisexual women having the highest risk. CONCLUSION: Bisexual women appear to be a particularly vulnerable sexual minority group. Advocating for non-discrimination and protections for lesbian, gay, and bisexual people is a logical extension of the effort to lower the prevalence of mental illness.

Association between childhood adversity and a diagnosis of personality disorder in young adulthood: a cohort study of 107,287 individuals in Stockholm County.

Childhood adversity (CA) may increase the risk for later developing of personality disorder (PD). However, less is known about the association between cumulative CA and PD, and the role of childhood psychopathology and school performance. The current study examined the relationship between a range of CAs and a diagnosis of PD in young adulthood, and the roles of childhood psychopathology and school performance in this relationship. All individuals born in Stockholm County 1987-1991 (n = 107,287) constituted our cohort. Seven CAs were measured between birth and age 14: familial death, parental criminality, parental substance abuse and psychiatric morbidity, parental separation and/or single-parent household, household public assistance and residential instability. Individuals were followed from their 18th birthday until they were diagnosed with PD or until end of follow-up (December 31st 2011). Adjusted estimates of risk of PD were calculated as hazard ratios (HR) with 95% confidence intervals (CI). Associations were observed between cumulative CA and PD. During the follow-up 770 individuals (0.7%) were diagnosed with PD. Individuals exposed to 3+ CAs had the highest risks of being diagnosed with PD (HR 3.0, 95% CI 2.4-3.7). Childhood psychopathology and low school grades further increased the risk of PD among individuals exposed to CA. Cumulative CA is strongly associated with a diagnosis of PD in young adulthood. Our findings indicate that special attention should be given in schools and health services to children exposed to adversities to prevent decline in school performance, and to detect vulnerable individuals that may be on negative life-course trajectories.

Sexual Orientation and All-Cause Mortality Among US Adults Aged 18 to 59 Years, 2001-2011.

To determine whether sexual minorities have an earlier mortality than do heterosexuals, we investigated associations between sexual orientation assessed in the 2001 to 2010 National Health and Nutrition Examination Surveys (NHANES) and mortality in the 2011 NHANES-linked mortality file. Mortality follow-up time averaged 69.6 months after NHANES. By 2011, 338 individuals had died. Sexual minorities evidenced greater all-cause mortality than did heterosexuals after adjusting for demographic confounding. These effects generally disappeared with further adjustment for NHANES-detected health and behavioral differences.

Suicide in married couples in Sweden: Is the risk greater in same-sex couples?

Minority sexual orientation is a predictor of suicide ideation and attempts, though its association with suicide mortality is less clear. We capitalize on Sweden's extensively linked databases, to investigate whether, among married individuals, same-sex marriage is associated with suicide. Using a population-based register design, we analyzed suicide risk among same-sex married women and men (n = 6456), as compared to different-sex married women and men (n = 1181723) in Sweden. We selected all newly partnered or married individuals in the intervening time between 1/1/1996 and 12/31/2009 and followed them with regard to suicide until 12/31/2011. Multivariate Poisson regression was used to calculate adjusted incidence risk ratios (IRR) with 95 % confidence intervals (CI). The risk of suicide was higher among same-sex married individuals as compared to different-sex married individuals (IRR 2.7, 95 % CI 1.5-4.8), after adjustment for time at risk and socioeconomic confounding. Sex-stratified analyses showed a tentatively elevated risk for same-sex married women (IRR 2.5, 95 % CI 0.8-7.7) as compared to different-sex married women. Among same-sex married men the suicide risk was nearly three-fold greater as compared to different-sex married (IRR 2.895 % CI 1.5-5.5). This holds true also after adjustment for HIV status. Even in a country with a comparatively tolerant climate regarding homosexuality such as Sweden, same-sex married individuals evidence a higher risk for suicide than other married individuals.

Excess cause-specific mortality in in-patient-treated individuals with personality disorder: 25-year nationwide population-based study.

BACKGROUND: Although personality disorders are associated with increased overall mortality, less is known about cause of death and personality type. AIMS: To determine causes of mortality in ICD personality disorders. METHOD: Based on data from Swedish nationwide registers, individuals admitted to hospital with a primary diagnosis of personality disorder between 1987 and 2011 were followed with respect to mortality until 31 December 2011. Standardised mortality ratios (SMRs) with 95% confidence intervals and underlying causes of death were calculated. RESULTS: All-cause SMRs were increased, overall and in all clusters, for natural as well as unnatural causes of death. The overall SMR was 6.1 in women and 5.0 in men, as high as previously reported for anorexia nervosa, with higher rates in cluster B and mixed/other personality disorders. The SMR for suicide was 34.5 in women and 16.0 in men for cluster B disorders. Somatic and psychiatric comorbidity increased SMRs. CONCLUSIONS: The SMR was substantially increased for all personality disorder clusters. Thus, there was an increased premature mortality risk for all personality disorders, irrespective of category.

Is disability pension a risk indicator for future need of psychiatric healthcare or suicidal behavior among MS patients- a nationwide register study in Sweden?

BACKGROUND: Mental disorders and suicidal behavior are common in patients with multiple sclerosis (MS), they also carry a higher risk of disability pension (DP). Our aim was to investigate if DP and other factors are associated with psychiatric disorders and suicidal behavior among MS patients, and whether DP is a stronger risk indicator among certain groups. METHOD: A prospective population-based cohort study with six-year follow-up (2005-2010), including 11 346 MS patients who in 2004 were aged 16-64 and lived in Sweden. Incidence rate ratios (IRR) with 95 % confidence intervals (CI) were calculated. RESULTS: MS patients on DP had a modestly higher risk of requiring psychiatric healthcare, IRR: 1.36 (95 % CI: 1.18-1.58). MS patients with previous psychiatric healthcare had a higher IRR for both psychiatric healthcare and suicidal behavior; 2.32 (2.18-2.47) and 1.91 (1.59-2.30), respectively. DP moderated the association between sex and psychiatric healthcare, where women on DP displayed higher risk than men, X(2) 4.74 (p = 0.03). CONCLUSION: The findings suggest that losing one's role in work life aggravates rather than alleviates the burden of MS, as MS patients on DP seem to have a higher need for psychiatric healthcare, especially among women; which calls for extra awareness among clinicians.

Co-morbidities increase the risk of disability pension among MS patients: a population-based nationwide cohort study.

BACKGROUND: Multiple sclerosis (MS) is a chronic and often disabling disease. In 2005, 62% of the MS patients in Sweden aged 16-65 years were on disability pension. The objective of this study is to investigate whether the presence of common co-morbidities increase MS patients' risk for disability pension. METHODS: This population-based cohort study included 4 519 MS patients and 4 972 174 non-MS patients who in 2005 were aged 17-64 years, lived in Sweden, and were not on disability pension. Patients with MS were identified in the nationwide in- and outpatient registers, while four different registers were used to construct three sets of measures of musculoskeletal, mental, and cardiovascular disorders. Time-dependent proportional hazard models with a five-year follow up were performed, adjusting for socio-demographic factors. RESULTS: All studied disorders were elevated among MS patients, regardless of type of measure used. MS patients with mental disorders had a higher risk for disability pension than MS patients with no such co-morbidities. Moreover, mental disorders had a synergistic influence on MS patients' risk for disability pension. These findings were also confirmed when conducting sensitivity analyses. Musculoskeletal disorders appeared to increase MS patients' risk for disability pension. The results with regard to musculoskeletal disorders' synergistic influence on disability pension were however inconclusive. Cardiovascular co-morbidity had no significant influence on MS-patients' risk for disability pension. CONCLUSIONS: Co-morbidities, especially mental disorders, significantly contribute to MS patients' risk of disability pension, a finding of relevance for MS management and treatment.

Suicide or undetermined intent? A register-based study of signs of misclassification.

BACKGROUND: Several studies have concluded that some deaths classified as undetermined intent are in fact suicides, and it is common in suicide research in Europe to include these deaths. Our aim was to investigate if information on background variables would be helpful in assessing if deaths classified as undetermined intent should be included in the analyses of suicides. METHODS: We performed a register study of 31,883 deaths classified as suicides and 9,196 deaths classified as undetermined intent in Sweden from 1987 to 2011. We compared suicide deaths with deaths classified as undetermined intent with regard to different background variables such as sex, age, country of birth, marital status, prior inpatient care for self-inflicted harm, alcohol and drug abuse, psychiatric inpatient care, and use of psychotropics. We also performed a multivariate analysis with logistic regression. RESULTS: Our results showed differences in most studied background factors. Higher education was more common in suicides; hospitalization for self-inflicted harm was more common among female suicides as was prior psychiatric inpatient care. Deaths in foreign-born men were classified as undetermined intent in a higher degree and hospitalization for substance abuse was more common in undetermined intents of both sexes. Roughly 50% of both suicide and deaths classified as undetermined intent had a filled prescription of psychotropics during their last six months. Our multivariate analysis showed male deaths to more likely be classified as suicide than female: OR: 1.13 (1.07-1.18). The probability of a death being classified as suicide was also increased for individuals aged 15-24, being born in Sweden, individuals who were married, and for deaths after 1987-1992. CONCLUSION: By analyzing Sweden's unique high-validity population-based register data, we found several differences in background variables between deaths classified as suicide and deaths classified as undetermined intent. However, we were not able to clearly distinguish these two death manners. For future research we suggest, separate analyses of the two different manners of death.

Diagnosis-specific disability pension and risk of all-cause and cause-specific mortality--a cohort study of 4.9 million inhabitants in Sweden.

BACKGROUND: The incidence of disability pension (DP) is high in several European countries. However, knowledge on associations of cause-specific DP and premature death is limited. The aims were to: 1) investigate the association between cause-specific DP and all-cause and cause-specific mortality among women and men and 2) examine period effects of this association. METHODS: Three prospective population-based cohort studies were conducted, the first including all individuals aged 16-64 years who lived in Sweden all of 1995 and who were not on DP before 1995 (N = 5,006,523, 48.8% women). Those granted DP in 1995 were compared to those not granted DP regarding mortality during 1996-2009. Two other cohorts were created in a similar fashion, for 2000 and 2005, respectively, and in comparisons each of the three cohorts were followed up for four years with regard to all-cause mortality as well as death due to cancer, circulatory disorders, or suicide. All analyses were stratified by sex and we controlled for a number of socio-demographic factors and inpatient care. RESULTS: Individuals with granted DP had a higher mortality risk, women (HR 1.75; 95% CI 1.68-1.82) and men (HR 1.66; 95% CI 1.61-1.71) and highest for cancer. People on DP with some diagnoses had higher risk of premature death in other causes of death than their DP diagnoses. All-cause mortality risk varied with DP-diagnosis and was lowest for musculoskeletal diagnoses. The mortality HR decreased among women with DP between the cohort 1995, HR 2.07 (1.92-2.24) and the cohort 2005, 1.84 (1.71-1.99). Here, temporal decreases in mortality risk occurred particularly in DP due to mental diagnoses and cancer. CONCLUSIONS: All DP diagnoses were associated with a higher mortality risk. Even individuals granted DP due to diagnoses with low mortality risk displayed a higher risk for premature death. This warrants close monitoring of disability pensioners and further studies on consequences of being on disability pension.

Associations between number of sick-leave days and future all-cause and cause-specific mortality: a population-based cohort study.

BACKGROUND: As the number of studies on the future situation of sickness absentees still is very limited, we aimed to investigate the association between number of sick-leave days and future all-cause and cause-specific mortality among women and men. METHODS: A cohort of 2 275 987 women and 2 393 248 men, aged 20-64 years in 1995 was followed 1996-2006 with regard to mortality. Data were obtained from linked authority-administered registers. The relative risks (RR) and 95% confidence intervals (CI) of mortality with and without a 2-year wash-out period were estimated by multivariate Poisson regression analyses. All analyses were stratified by sex, adjusting for socio demographics and inpatient care. RESULTS: A gradually higher all-cause mortality risk occurred with increasing number of sick-leave days in 1995, among both women (RR 1.11; CI 1.07-1.15 for those with 1-15 sick-leave days to RR 2.45; CI 2.36-2.53 among those with 166-365 days) and men (RR 1.20; CI 1.17-1.24 to RR 1.91; CI 1.85-1.97). Multivariate risk estimates were comparable for the different causes of death (circulatory disease, cancer, and suicide). The two-year washout period had only a minor effect on the risk estimates. CONCLUSION: Even a low number of sick-leave days was associated with a higher risk for premature death in the following 11 years, also when adjusting for morbidity. This was the case for both women and men and also for cause-specific mortality. More knowledge is warranted on the mechanisms leading to higher mortality risks among sickness absentees, as sickness certification is a common measure in health care, and most sick leave is due to diagnoses you do not die from.

Variation and seasonal patterns of suicide mortality in Finland and Sweden since the 1750s.

OBJECTIVES: Suicide mortality varies in both the short and long term. Our study examines suicide mortality in Finland and Sweden from the 1750s until today. The aim of our study is to detect any seasonal peaks in suicide rates and examine their temporal evolution to suggest a mechanism that may explain such peaks. METHOD: We acquired the study material from the Finnish and Swedish cause of death statistics (257,341 deaths by suicide) and the relevant population gender structure data. We then separately calculated the annual male and female suicide rates per 100,000 inhabitants. We analysed the suicide peaks, calculating factors of proportionality for the available data by dividing the suicide rates in the peak months (May and October) by the annual suicide rates. RESULTS: Suicide rates in Finland and Sweden peak twice a year. Both men and women in both countries most often commit suicide in May. There is another peak in October, with the exception of Finnish men. These suicide peaks coincide with a temperature increase in May and the biggest annual drop in temperature in October. We also observed a monotonic long-term change in the Swedish statistics, but not in the Finnish data. Our hypothesis is that seasonal variation in suicide rates may be caused by abrupt temperature changes twice a year that trigger the activity in brown adipose tissue and deepen depression. CONCLUSION: While the overall suicide mortality rates varied considerably, the monthly proportions in May did not. This finding suggests a routine factor underlying the spring peak in suicide mortality.

Effect of comorbid ADHD on mortality in women with borderline personality disorder.

BACKGROUND: Many similarities exist between borderline personality disorder (BPD) and attention-deficit/hyperactivity disorder (ADHD), more so in women than in men. People with comorbid ADHD and BPD represent a subgroup of BPD patients with distinct symptom expression and, consequently, a different prognosis. We used Swedish national high quality registers to assess whether such comorbidity is related to increased mortality risk. The study focused on women with BPD because they are more likely than men to be clinically diagnosed with BPD and present a higher mortality risk, especially for unnatural causes of death, including suicide. FINDINGS: In a cohort of 15 847 women diagnosed with BPD a subsequent clinical diagnosis of ADHD did not influence the overall risk of mortality, including suicide. CONCLUSIONS: Women with comorbid ADHD and BPD have a similar mortality risk as those only diagnosed with BPD.
