Differences in how women and men in a Swedish population-based sample think about sick leave: A cross-sectional vignette study.

Gender differences in attitudes towards depression gives reason to believe that sociocultural gender norms play a role in other areas. The aim was to test (i) if the likelihood to think that sick leave with depression symptoms is not reasonable varies between women and men, and (ii) if the likelihood to think sick leave is not reasonable varies depending on the gender of the individual with depression symptoms. A study population of 3147 participants responded to a web-survey with a written case briefly describing a man or woman with symptoms of depression. Respondents were asked if they thought it is reasonable that the person was sick listed for two weeks. Logistic regression was used to analyse the data. After controlling for age, education, self-rated health, and respondent's own experience of sickness absence the adjusted OR was 1.45 (95% CI 1.25-1.67) for men being less likely to think sick-leave was reasonable. Gender difference decreased when adjusting for negative attitudes towards depression (adjusted OR 1.24, 95% CI 1.06-1.44). No difference was found between how women and men thought about sick leave in relation to the gender of the case described in the vignette. Men were more likely to think that sick leave was not reasonable with decreased OR after adjustment for negative attitudes towards depression. Gender norms might be part of the explanation for differences but are challenging to test. This study contributes to a bourgeoning research field on gendered attitudes and sick leave, in terms of theoretical reasoning and methodological choice.

Prevalence and heritability of parental-reported speech and/or language difficulties in a Swedish population-based twin sample.

Research on genetic and environmental influences on speech and/or language difficulties (SaLD) is sparse, with inconsistent heritability estimates. We aimed to estimate the prevalence of parental reported SaLD and the relative contributions of genetic and environmental factors for the phenotype using a Swedish population-based twin sample. We hypothesized that there would be a stronger genetic than environmental effect on SaLD. Data were collected from The Child and Adolescent Twin Study in Sweden. The study sample included 16,774 twin pairs (16,946 males, 16,602 females), of which 5141 were monozygotic, 5861 dizygotic (DZ), and 5772 opposite-sex DZ pairs. The language items in the Autism-Tics, Attention-Deficit Hyperactivity Disorder, and other Comorbidities inventory were used to categorize individuals as having parental-reported SaLD. A classical twin design was used to estimate the relative contribution of genetic and environmental factors to the liability of SaLD. The prevalence of SaLD was 7.85% (95% confidence interval (CI) [7.57%-8.15%]) and 7.27% (95% CI [6.99%-7.55%]) when excluding individuals with autism and intellectual disability (ID). We also found that SaLD were significantly more prevalent in males than females with a ratio of 2:1. The heritability was estimated to be 75% (95% CI [67%-83%]) for SaLD. Shared environment played a significant role with an estimated contribution of 22% (95% CI [14%-30%]). The heritability estimate was reduced to 70% but with overlapping CI when excluding individuals with autism and ID. We provide evidence that SaLD is common in the population and under strong genetic influence. Future studies should focus on mapping the genetic architecture of SaLD and related disorders.

Risk factors for insomnia and burnout: A longitudinal population-based cohort study.

Insomnia and burnout are highly prevalent in the general population, calling for understanding of its causes. Taking a broad approach, the aim of this study was to determine various mental and somatic risk factors for development of insomnia and burnout and stratifying for sex and age group. Questionnaire data were used from a Swedish population-based sample aged 18-79years, from which cohorts without insomnia (n=1702) and without burnout (n=1972) at baseline were followed-up after 3 years. Self-reports of eight mental and somatic conditions at baseline were used as independent variables in logistic regression analyses to predict development of insomnia and burnout at 3-year follow-up. All eight studied conditions were significant risk factors for development of both insomnia (odds ratio, OR=1.62-2.73) and burnout (OR=2.20-3.21). Burnout and poor self-rated health had the highest ORs for insomnia, and poor self-rated health, anxiety and somatic symptoms had the highest ORs for burnout. The ORs were generally similar between men and women, whereas age groups tended to differ in some of the risk factors. The study highlights the importance of a broad assessment of both mental and somatic conditions in the prevention of insomnia and burnout.

The Typology of Alcohol Use Disorder: Latent Class Analyses of a Population-Based Swedish Sample.

The purpose of this study was to clarify the clinical heterogeneity of alcohol use disorder (AUD) in a national Swedish sample of affected individuals using latent class analysis. Using a Swedish population-based sample of AUD cases ascertained from medical, criminal, and pharmacy registries (n = 217,071), we applied latent class analysis to sex, externalizing and internalizing syndromes before first registration, and age at first registration. The resulting types were evaluated against 15 diverse validators and degree of resemblance in relative pairs concordant for AUD. A three-class solution was preferred by fit indices. The three classes were as follows: type 1 (male preponderant, externalizing; 32%), type 2 (minimal prior psychopathology; 46%), and type 3 (mixed-sex internalizing; 23%). Repeated split-half analyses revealed the statistical stability of these solutions. Meaningful differences emerged between the classes on many validators. Type 1 had the greatest family disruption, lowest educational levels, most AUD registrations, highest rates of criminal registration, and highest genetic risk for externalizing disorders and AUD. Type 2 had the least social dysfunction. Type 3 had the highest educational attainment, genetic liability to internalizing disorders, and proportion of women. All types significantly aggregated in affected pairs of relatives. Meaningful and reproducible subtypes of AUD, consistent with prior typological results, can be obtained from national registry-based samples. Using a range of external validators and patterns of familial aggregation, our results suggest that our three-class solution captured a meaningful proportion of the clinical heterogeneity of AUD.

Mental health in children of parents being treated by specialised psychiatric services.

One in ten children have a parent diagnosed with a mental illness by specialised psychiatric services. Severe parental mental illness is a well-established risk factor for children's mental health problems, making the identification and support of these children a public health concern. This study investigated the mental health and family context of children of parents diagnosed with depression, anxiety, or bipolar disorder in this clinical setting. Parental reports on 87 children aged 8-17 years were analysed. The children's mental health was compared with that of a Swedish population-based sample. Multiple linear regression was used to investigate associations between child mental health and child gender, child age, parent symptoms and social status, family functioning, and perceived parental control. Furthermore, a cumulative risk index explored the effect of multiple risk factors on child mental health. The children reportedly had significantly more mental health problems than did the population-based sample and about one-third had scores above the clinical cut-off. A significant multiple linear regression explained 49% of the variance in child mental health, with lower perceived parental control and younger child age being associated with more child mental health problems. With more reported risk factors, children reportedly had more mental health problems. The results underline the importance of identifying a patient's children and assessing multiple relevant risk factors in the child's life. Furthermore, the results indicate that the needs of younger children and of patients in their parenting role are important to address.

The role of sickness absence diagnosis for the risk of future inpatient- or specialized outpatient care in a Swedish population-based twin sample

BackgroundStudies of consequences of sickness absence such as health and well-being have been rare whereas risk factors for sickness absence have been studied extensively. This study assumed the consequences of sickness absence would differ by diagnostic group or by patient care type. The aim was to investigate sickness absence due to various diagnosis groups as a predictor for subsequent inpatient- and specialized outpatient care while controlling for familial confounding.MethodsWe utilized the register data of 69,552 twin individuals between 16 and 80 years of age (48% women). The first incident sickness absence spell, from baseline year 2005, including diagnosis of sickness absence was our primary exposure of interest and we followed them until the first incident inpatient- and specialized outpatient care episode with main diagnosis code or until 31.12.2013.ResultsA total of 7464 incident sickness absence spells took place (11%), 42% had inpatient care and 83% specialized outpatient care (mean follow-up time 3.2 years, SD 3.1 years). All the main sickness absence diagnosis groups were associated with increased risk of future care in comparison to no sickness absence. Controlling for confounders attenuated the associations in magnitude but with retaining direction, and we could not confirm an effect of familial factors.ConclusionsSickness absence predicts both inpatient- and specialized outpatient care and the association is universal across diagnosis groups. The lower survival time and incidence rates of inpatient than specialized outpatient care point towards severity of diseases assumption. This finding was also universal across sickness absence diagnosis groups.

The association between family history and genomic burden with schizophrenia mortality: a Swedish population-based register and genetic sample study

Individuals with schizophrenia (SCZ) have a 2–3-fold higher risk of mortality than the general population. Heritability of mortality in psychiatric disorders has been proposed; however, few have investigated SCZ family history and genetic variation, with all-cause and specific causes of death. We aimed to identify correlates of SCZ mortality using genetic epidemiological and genetic modelling in two samples: a Swedish national population sample and a genotyped subsample. In the Swedish national population sample followed from the first SCZ treatment contact until emigration, death or end of the follow-up, we investigated a standardised measure of SCZ family history. In a subgroup with comprehensive genetic data, we investigated the impact of common and rare genetic variation. Cox proportional hazards regression was used to estimate the association between various factors and mortality (all and specific causes). A total of 13727 SCZ cases fulfilled criteria for the population-based analyses (1268 deaths, 9.2%). The genomic subset contained 4991 cases (1353 deaths, 27.1%). Somatic mutations associated with clonal hematopoiesis with unknown drivers were associated with all-cause mortality (HR 1.77, 95% CI: 1.26–2.49). No other heritable measures were associated with all-cause mortality nor with any specific causes of death. Future studies in larger, comparable cohorts are warranted to further understand the association between hereditary measures and mortality in SCZ.

Different Characteristics and Heritabilities of Alcohol Use Disorder Classes: A Population-Based Swedish Study.

The aims of the present study are to identify alcohol use disorder (AUD) classes among a population-based Swedish sample, determine if these classes differ by variables known to be associated with AUD and determine whether some AUD classes have stronger genetic influences than others. A latent class analysis (LCA), based on types of registrations, was conducted on Swedish individuals with an AUD registration born between 1960 and 1990 (N=184,770). These classes were then validated using demographics; patterns of comorbidity with drug abuse, psychiatric disorders and criminal behavior; and neighborhood-level factors, i.e. peer AUD and neighborhood deprivation. The degree of genetic and environmental influence was also investigated. The best-fit LCA had four classes: (a) outpatient/prescription, characterized by a mix of outpatient medical and prescription registrations, (b) low-frequency inpatient, characterized entirely by inpatient medical registrations, with the majority of individuals having one AUD registration, (c) high-frequency mixed, characterized by a mix of all four registration types, with the majority having four or more registrations and (d) crime, characterized almost entirely by criminal registrations. The highest heritability for both males and females was found for Class 3 (61% and 65%, respectively) and the lowest for Class 1 (20% for both), with shared environmental influences accounting for 10% or less of the variance in all Classes. Using comprehensive, nationwide registry data, we showed evidence for four distinct, meaningful classes of AUD with varying degrees of heritability.

Length of time periods in treatment effect descriptions and willingness to initiate preventive therapy: a randomised survey experiment

BackgroundCommon measures used to describe preventive treatment effects today are proportional, i.e. they compare the proportions of events in relative or absolute terms, however they are not easily interpreted from the patient’s perspective and different magnitudes do not seem to clearly discriminate between levels of effect presented to people.MethodsIn this randomised cross-sectional survey experiment, performed in a Swedish population-based sample (n = 1041, response rate 58.6%), the respondents, aged between 40 and 75 years were given information on a hypothetical preventive cardiovascular treatment. Respondents were randomised into groups in which the treatment was described as having the effect of delaying a heart attack for different periods of time (Delay of Event, DoE): 1 month, 6 months or 18 months. Respondents were thereafter asked about their willingness to initiate such therapy, as well as questions about how they valued the proposed therapy.ResultsLonger DoE:s were associated with comparatively greater willingness to initiate treatment. The proportions accepting treatment were 81, 71 and 46% when postponement was 18 months, 6 months and 1 month respectively. In adjusted binary logistic regression models the odds ratio for being willing to take therapy was 4.45 (95% CI 2.72–7.30) for a DoE of 6 months, and 6.08 (95% CI 3.61–10.23) for a DoE of 18 months compared with a DoE of 1 month. Greater belief in the necessity of medical treatment increased the odds of being willing to initiate therapy.ConclusionsLay people’s willingness to initiate preventive therapy was sensitive to the magnitude of the effect presented as DoE. The results indicate that DoE is a comprehensible effect measure, of potential value in shared clinical decision-making.

Self-Reported Negative Influence of Gambling Advertising in a Swedish Population-Based Sample

This study investigated the negative influence of gambling advertising, that is, gambling more often or for more money than intended. We analyzed data from wave four of the Swedish Longitudinal Gambling Study (Swelogs), in which the self-perceived negative influence of gambling advertising was measured by responses to three survey questions. Few gamblers reported having been negatively influenced by gambling advertising. Among those who reported such influence, problem gamblers were overrepresented. Those who had set limits for their gambling reported a negative influence from advertising more often than others, which likely was caused by a perception that advertising is detrimental to efforts to cut down on excessive gambling. A multivariate regression analysis showed that negative influence from gambling advertising was positively associated with problem gambling, gambling at least monthly, participation in online gambling, and being in the age group 30–49 years. We conclude that although few gamblers are negatively influenced by gambling advertising, the adverse effects on those that are should not be neglected. For a considerable number of people, gambling advertising substantially contributes to problem gambling.

Lower risk of hip fractures among Swedish women with large hips?

SummaryIn women, a large hip circumference (HC) related to lower hip fracture risk, independent of age and regardless if HC was measured long before or closer to the fracture. In older women, body mass index (BMI) explained the protection.IntroductionIn postmenopausal women, HC has been suggested to inversely associate with hip fracture while this has not been investigated in middle-aged women. We examined the association between HC, measured at two different time points, and hip fracture in a Swedish female population-based sample monitored for incident hip fractures over many years.MethodsBaseline HC, measured in 1968 or 1974 (n = 1451, mean age 47.6 years), or the HC measures that were the most proximal before event or censoring (n = 1325, mean age 71.7 years), were used to assess the effects of HC on hip fracture risk in women participating in the Prospective Population Study of Women in Gothenburg. HC was parameterized as quintiles with the lowest quintile (Q1) as reference. Incident hip fractures over 45 years of follow-up (n = 257) were identified through hospital registers.ResultsHigher quintiles of HC at both baseline and proximal to event were inversely associated with hip fracture risk in age-adjusted models, but only baseline HC predicted hip fractures independently of BMI and other covariates (HR (95% CI) Q2, 0.85 (0.56–1.27); Q3, 0.59 (0.36–0.96); Q4, 0.57 (0.34–0.96); Q5, 0.58 (0.31–1.10)).ConclusionsA large HC is protective against hip fracture in midlife and in advanced age, but the association between proximal HC and hip fracture was explained by concurrent BMI suggesting that padding was not the main mechanism for the association. The independent protection seen in middle-aged women points to other mechanisms influencing bone strength.

Psychological Health in the Retirement Transition: Rationale and First Findings in the HEalth, Ageing and Retirement Transitions in Sweden (HEARTS) Study.

From an aging research and life-course perspective, the transition to retirement marks a significant life-event and provides a unique opportunity to study psychological health and coping during a period of substantial change in everyday life. The aim of the present paper is to: (a) outline the rationale of the HEalth, Ageing and Retirement Transitions in Sweden (HEARTS) study, (b) describe the study sample, and (c) to present some initial results from the two first waves regarding the association between retirement status and psychological health. The HEARTS study is designed to annually study psychological health in the years before and following retirement, and to examine change and stability patterns related to the retirement event. Among a representative Swedish population-based sample of 14,990 individuals aged 60–66 years, 5,913 completed the baseline questionnaire in 2015. The majority of the participants (69%) completed a web-based survey, and the rest (31%) completed a paper version. The baseline HEARTS sample represents the general population well in terms of gender and age, but is more highly educated. Cross-sectional findings from the first wave showed that retired individuals demonstrated better psychological health compared to those who were still working. Longitudinal results from the first and second waves showed that individuals who retired between waves showed more positive changes in psychological health compared with those still working or previously retired.

Adult attachment's unique contribution in the prediction of postpartum depressive symptoms, beyond personality traits

BackgroundPersonality traits such as neuroticism can help identify pregnant women at risk of postpartum depressive symptoms (PPDS). However, it is unclear whether attachment style could have an additional contribution to this risk elevation. This study aimed to examine the overlap of adult attachment insecurity and neuroticism/trait anxiety as PPDS predictors, taking into account baseline depressive symptoms. MethodsA Swedish population-based sample of pregnant women reported on adult attachment and either neuroticism (n = 1063) or trait anxiety (n = 555). Depressive symptoms were assessed at baseline, and at six weeks and six months postpartum. Correlations between attachment and neuroticism/trait anxiety were calculated. Generalized linear models of PPDS tested the effect of attachment anxiety and avoidance, adjusting for neuroticism/trait anxiety and baseline depression. Logistic regression models with combined high attachment anxiety and neuroticism/trait anxiety visualized their value as risk factors beyond antenatal depression. ResultsAttachment and neuroticism/trait anxiety were highly correlated (r = .55–.77). Attachment anxiety exerted a partially independent effect on PPDS at six weeks (p < .05) and at six months (p < .05) adjusting for neuroticism. Among antenatally non-depressed, combined high attachment anxiety and high neuroticism or trait anxiety was predictive of PPDS at both assessment points. LimitationsLow acceptance rate, exclusive use of self-reports. ConclusionsBeyond personality, attachment anxiety had a small independent effect on the risk of PPDS. Combining items of adult attachment and neuroticism/trait anxiety could prove useful in antenatal screening for high risk of PPDS.

Shift work and cognitive aging: a longitudinal study.

Objectives The few studies of shift work and late life cognitive functioning have yielded mixed findings. The aim of the present study is to estimate the association between shift-work experience and change in cognitive performance before and after retirement age among older adults who were gainfully employed. Methods Five hundred and ninety five participants with no dementia were followed up for a mean of 17.6 standard deviation (SD) 8.8 years from a Swedish population-based sample. Participants had self-reported information on any type of shift-work experience (ever/never) in 1984 and measures of cognitive performance (verbal, spatial, memory, processing speed, and general cognitive ability) from up to 9 waves of cognitive assessments during 1986-2012. Night work history (ever/never) from 1998-2002 was available from a subsample (N=320). Early adult cognitive test scores were available for 77 men. Results In latent growth curve modeling, there were no main effects of "any-type" or night shift work on the mean scores or rate of change in any of the cognitive domains. An interaction effect between any-type shift work and education on cognitive performance at retirement was noted. Lower-educated shift workers performed better on cognitive tests than lower-educated day workers at retirement. Sensitivity analyses, however, indicated that the interactions appeared to be driven by selection effects. Lower-educated day workers demonstrated poorer cognitive ability in early adulthood than lower-educated shift workers, who may have selected jobs entailing higher cognitive demand. Conclusion There was no difference in late-life cognitive aging between individuals with a history of working shifts compared to those who had typical day work schedules during midlife.

Population-based incidence and clinical characteristics of idiopathic intracranial hypertension.

To validate the diagnosis of idiopathic intracranial hypertension (IIH) from the Swedish National Patient Register (NPR) and investigate the incidence of IIH, as well as co-morbidities and medication use in a large Swedish population-based sample. We searched the NPR to find all patients ≥18years old with the ICD-10 diagnosis code (G93.2) for IIH in Stockholm County from Jan 1, 2006, to Dec 31, 2013. All medical records were reviewed to validate the diagnosis and to collect additional information. We included 207 patients with an IIH diagnosis, of which 135 (65%) were correctly diagnosed when validated by charts review. Eighty-three patients had disease onset during the study period. This gave a yearly incidence of 0.65/100000. Female-to-male ratio was 6.1:1. Females, mean age 31.0 (CI 28.8-33.1), were younger at time of diagnosis compared to males, mean age 42.9 (CI 36.4-49.5), P<.001. The most common co-morbidities were obesity (92%), hormonal conditions (21%) and recent infections preceding the diagnosis (21%). Prior treatment with tetracycline derivatives were seen in 9%. The incidence of IIH in Stockholm is in the lower range of previously reported rates, possibly due to a lower prevalence of obesity. A substantial proportion of patients (35%) did not fulfill diagnostic criteria. Disease onset occurs at younger age in females. Co-morbidities were mainly associated with diseases affecting hormonal balance or causing inflammatory activation. These findings raise new hypothetical theories regarding mechanisms involved in IIH pathogenesis.

The role of online social network chatting for alcohol use in adolescence: Testing three peer-related pathways in a Swedish population-based sample

The aim of the study was to examine whether online social network chatting (OSNC) is related to any of three peer-related pathways to alcohol use among adolescents including a stress-exposure pathway, a peer status pathway and a social context pathway. A survey was distributed to a Swedish population-based sample of 2439 boys and girls 15–16 years old enrolled in the 9th grade of primary school. Indirect effects, moderating effects, and gender differences were analysed. The results exposed a robust positive association between OSNC and alcohol use, but also that OSNC accounted for one-fifth of the association between the peer status pathway and alcohol use. A positive association between the stress-exposure pathway and alcohol use was found that was weaker among adolescents who scored high on OSNC whereas a positive association between the social context pathway and alcohol use also was found that was stronger among adolescents who scored high on OSNC. Consequently, OSNC may contribute differently to alcohol use depending on which peer-related pathway that the adolescent follows. The robust positive association between OSNC and alcohol use that remained when the three peer-related pathways were accounted for also indicates that this association is accounted for by other factors.

Alcohol use disorder and divorce: evidence for a genetic correlation in a population-based Swedish sample.

We tested the association between alcohol use disorder (AUD) and divorce; estimated the genetic and environmental influences on divorce; estimated how much genetic and environmental influences accounted for covariance between AUD and divorce; and estimated latent genetic and environmental correlations between AUD and divorce. We tested sex differences in these effects. We identified twin and sibling pairs with AUD and divorce information in Swedish national registers. We described the association between AUD and divorce using tetrachorics and used twin and sibling models to estimate genetic and environmental influences on divorce, on the covariance between AUD and divorce and the latent genetic and environmental correlations between AUD and divorce. Sweden. A total of 670 836 individuals (53% male) born 1940-1965. Life-time measures of AUD and divorce. AUD and divorce were related strongly (males: rtet =+0.44, 95% CI=0.43, 0.45; females rtet =+0.37, 95% CI=0.36, 0.38). Genetic factors accounted for a modest proportion of the variance in divorce (males: 21.3%, 95% CI=7.6, 28.5; females: 31.0%, 95% CI=18.8, 37.1). Genetic factors accounted for most of the covariance between AUD and divorce (males: 52.0%, 95% CI=48.8, 67.9; females: 53.74%, 95% CI=17.6, 54.5), followed by non-shared environmental factors (males: 45.0%, 95% CI=37.5, 54.9; females: 41.6%, 95% CI=40.3, 60.2). Shared environmental factors accounted for a negligible proportion of the covariance (males: 3.0%, 95% CI=-3.0, 13.5; females: 4.75%, 95% CI=0.0, 6.6). The AUD-divorce genetic correlations were high (males: rA=+0.76, 95% CI=0.53, 0.90; females +0.52, 95% CI=0.24, 0.67). The non-shared environmental correlations were modest (males: rE=+0.32, 95% CI=0.31, 0.40; females: +0.27, 95% CI=0.27, 0.36). Divorce and alcohol use disorder are correlated strongly in the Swedish population, and the heritability of divorce is consistent with previous studies. Covariation between AUD and divorce results from overlapping genetic and non-shared environmental factors. Latent genetic and non-shared environmental correlations for alcohol use disorder and divorce are high and moderate.

Divorce and the Onset of Alcohol Use Disorder: A Swedish Population-Based Longitudinal Cohort and Co-Relative Study

The purpose of this study was to clarify the magnitude and nature of the relationship between divorce and risk for alcohol use disorder (AUD). In a population-based Swedish sample of married individuals (N=942,366), the authors examined the association between divorce or widowhood and risk for first registration for AUD. AUD was assessed using medical, criminal, and pharmacy registries. Divorce was strongly associated with risk for first AUD onset in both men (hazard ratio=5.98, 95% CI=5.65-6.33) and women (hazard ratio=7.29, 95% CI=6.72-7.91). The hazard ratio was estimated for AUD onset given divorce among discordant monozygotic twins to equal 3.45 and 3.62 in men and women, respectively. Divorce was also associated with an AUD recurrence in those with AUD registrations before marriage. Furthermore, widowhood increased risk for AUD in men (hazard ratio=3.85, 95% CI=2.81-5.28) and women (hazard ratio=4.10, 95% CI=2.98-5.64). Among divorced individuals, remarriage was associated with a large decline in AUD in both sexes (men: hazard ratio=0.56, 95% CI=0.52-0.64; women: hazard ratio=0.61, 95% CI=0.55-0.69). Divorce produced a greater increase in first AUD onset in those with a family history of AUD or with prior externalizing behaviors. Spousal loss through divorce or bereavement is associated with a large enduring increased AUD risk. This association likely reflects both causal and noncausal processes. That the AUD status of the spouse alters this association highlights the importance of spouse characteristics for the behavioral health consequences of spousal loss. The pronounced elevation in AUD risk following divorce or widowhood, and the protective effect of remarriage against subsequent AUD, speaks to the profound impact of marriage on problematic alcohol use.

How are social capital and sense of coherence associated with hazardous alcohol use? Findings from a large population-based Swedish sample of adults.

This study examined whether social capital and a sense of coherence are associated with hazardous alcohol use in a large population-based Swedish sample. In particular, the objectives were (a) to examine which of five subdimensions of social capital is associated with hazardous alcohol use, (b) to investigate the moderating role of sense of coherence and (c) to examine possible sex differences. A postal survey was distributed to a sample of respondents (aged 18-84 years) from five Swedish counties that was stratified by sex, age and city; 40,674 (59.2%) participants responded, of which 45.5% were men and 54.5% were women with a mean±SD age of 53.8±17.9 years. Structural dimensions of social capital were associated with an increased probability of hazardous alcohol use among both men and women, whereas the increased probability associated with cognitive dimensions occurred mostly among women. Sense of coherence was robustly associated with a decreased probability of hazardous alcohol use among both men and women. There were few moderating effects of sense of coherence and sex differences emerged mainly for the cognitive dimension of social capital. CONCLUSIONS ASSOCIATIONS BETWEEN SOCIAL CAPITAL DIMENSIONS AND HAZARDOUS ALCOHOL USE WERE PARTLY SEX-SPECIFIC, WHEREAS THE BENEFITS OF A SENSE OF COHERENCE ACCRUED TO BOTH SEXES SOCIAL CAPITAL DIMENSIONS AND SENSE OF COHERENCE WERE GENERALLY UNRELATED TO EACH OTHER ONLY ASSOCIATIONS BETWEEN THE COGNITIVE DIMENSIONS OF SOCIAL CAPITAL AND HAZARDOUS ALCOHOL USE DIFFERED BY SEX.

Knowledge and Attitudes towards Antibiotic Use and Resistance - A Latent Class Analysis of a Swedish Population-Based Sample.

BackgroundIn 2006, a study investigating knowledge and attitudes regarding antibiotic use and resistance in Sweden, indicated high level of knowledge but also areas in need of improvement.Objective(i) To provide an update on the knowledge and attitudes to antibiotic use and resistance of the Swedish population, and (ii) to identify which groups within the population are in particular need of improved knowledge or attitudes.MethodsA questionnaire was sent by post in 2013 to 2,500 randomly-selected individuals aged 18–74, living in Sweden. Latent class analyses were conducted to group respondents based on their responses. The association between socio-demographic characteristics and the probability of belonging to each latent class was assessed.ResultsThe response rate was 57%. Ninety-four per cent of the responders knew that bacteria could become resistant to antibiotics and the majority answered correctly to the questions regarding antibiotic resistance development. The respondents expressed confidence in doctors who decided not to prescribe antibiotics. Three latent classes related to ‘knowledge regarding antibiotic use and resistance’, two regarding ‘attitudes towards antibiotic accessibility and infection prevention’ and three regarding ‘attitudes towards antibiotic use and effects’ were revealed. Men, younger and more educated people were more knowledgeable but males had a less restrictive attitude. Respondents with high levels of knowledge on antibiotics were more likely to have appropriate restrictive attitudes to antibiotics.ConclusionKnowledge on antibiotic use and resistance is maintained high and has improved in Sweden compared to 2006. People with lower education and elderly are especially in need of improved knowledge about antibiotic use and resistance.
