- Background: This cross-sectional study of two middle-aged community samples from Sweden and Russia examined the distribution of perceived control scores in the two populations, investigated differences in individual control items between the populations, and assessed the association between perceived control and self-rated health. Methods: The samples consisted of men and women aged 45–69 years, randomly selected from national and local population registers in southeast Sweden (n = 1007) and in Novosibirsk, Russia (n = 9231). Data were collected by structured questionnaires and clinical measures at a visit to a clinic. The questionnaire covered socioeconomic and lifestyle factors, societal circumstances, and psychosocial measures. Self-rated health was assessed by standard single question with five possible answers, with a cut-off point at the top two alternatives. Results: 32.2 % of Swedish men and women reported good health, compared to 10.3 % of Russian men and women. Levels of perceived control were also significantly lower in Russia than in Sweden and varied by socio-demographic parameters in both populations. Sub-item analysis of the control questionnaire revealed substantial differences between the populations both in the perception of control over life and over health. Logistic regression analysis revealed that the odds ratios (OR) of poor self-rated health were significantly increased in men and women with low perceived control in both countries (OR between 2.61 and 4.26). Conclusions: Although the cross-sectional design does not allow causal inference, these results support the view that perceived control influences health, and that it may mediate the link between socioeconomic hardship and health.

- Previous longitudinal studies have demonstrated the importance of measuring stability of risk factors over time to correct for attenuation bias. The present aim was to assess the stability of scores for eight psychometric scales over a 2-yr. period and whether stability differed by socioeconomic position. Baseline data were collected during 2003–2004 from 1,007 men and women ages 45 to 69 years. Follow-up data were collected in 2006 from a total of 795 men and women. Analysis showed that stability over 2 yr. was moderate and tended to be lower in groups of low socioeconomic position. It is suggested that correction of attenuation bias is relevant in longitudinal studies for psychosocial factors, especially for groups of low socioeconomic position.

- Objective Associations between subjective status and health are still relatively unexplored. This study aimed at testing whether subjective status is uniquely confounded by psychosocial factors compared to objective status, and what factors that may predict subjective status. Design A cross-sectional analysis of a population-based, random sample of 795 middle-aged men and women from the southeast of Sweden. Questionnaires included subjective status, objective measures of socioeconomic status, life satisfaction, and a battery of psychosocial factors. Associations were controlled for effects of age and sex. Results Both subjective status and occupation were significantly associated with self-rated health also after control for psychosocial factors. Stepwise regression showed that subjective status was significantly influenced by self-rated economy, education, life satisfaction, self-esteem, trust, perceived control, and mastery. Conclusion The association between subjective status and self-rated health does not seem to be uniquely confounded by psychosocial factors. Both resource-based measures and psychological dimensions seem to influence subjective status ratings. Comparative studies are required to study whether predictors of subjective status vary between countries with different socio-political profiles.

Social status : a state of mind?
- 2008

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is concerned with social stratification of psychosocial factors and social position measurement in population samples collected in mid-Sweden 2000-2006. Traditional resource-based measures of social position (occupation, education) and so far less explored prestige-based measures (subjective status, status incongruence) are tested with respect to their associations with psychosocial factors, emotions, and selfrated health. Three papers in this thesis are based on data from the Life Conditions, Stress, and Health (LSH) study, using a randomly selected population sample. Data for the fourth paper is a regional sample drawn from the health-related survey “Liv och Hälsa 2000”. Statistical methods range from correlation analysis to logistic regression and repeated measures analyses.Results from studies I and IV show that psychosocial factors are unequally distributed within the population in a linear manner, so that the lower the socioeconomic position (SEP), the more unfavourable levels. This is independent of whether we study this in a highly unequal setting such as Russia, or in a more egalitarian society such as Sweden. The stability of psychometric instruments over two years tend to be lower for all instruments among low SEP groups, and differ significantly for self-esteem and perceived control among groups with high and low education, and for cynicism among groups with high and low occupational status. Results from studies II and III point to the relevance of individuals’ own thoughts about themselves, and the potential impact on the self by normative judgements of social position in a certain hierarchical setting. In paper II, the prestige-based measure of subjective status was influenced by resource-based measures, such as self-rated economy and education, but also by life satisfaction and psychosocial factors. The importance of self-evaluation was especially obvious from the study on status incongruence (study III) where the traditionally protective effecs of a high education seem to disappear when combined with a lowstatus occupation. Shaming experiences may play an important role here for our understanding of self-perception.

- Study purpose: Status incongruence has been related to poor health and all-cause mortality, and could be a growing public health problem due to changes in the labour market in later decades. Shaming experiences have been suggested as playing a part in the aetiology. Our aim was to study the risk for shaming experiences, pessimism, anxiety, depressive feelings, and poor mental well-being (GHQ) with a special focus on shame, in four status categories: negatively and positively incongruent individuals, and low-status and high-status congruent individuals. Method: Data comprised 14 854 working men and women from a regional sample of randomly selected respondents, 18-79 years. Logistic regression was used to study differences in risk for negative emotional outcomes. Results: The negative incongruent category persisted as the group most at risk for all negative emotional outcomes (OR 1.5-1.9; p<0.05-<0.001). When testing the risk for poor mental well-being among the status categories with and without shaming experiences, OR for all groups with shaming experiences were elevated. Among groups without shame, only the negative incongruent category remained at risk (OR 2.7; p<0.05) after adjustment. Conclusion: Negative incongruent status is associated with adverse emotional outcomes, among them shame, which is a previously unappreciated aspect of status incongruence.

- Objective Copy number variation of the C4 complement components, C4A and C4B, has been associated with systemic inflammatory autoimmune diseases. This study was undertaken to investigate whether C4 copy number variation is connected to the autoimmune repertoire in systemic lupus erythematosus (SLE), primary Sjogrens syndrome (SS), or myositis. Methods Using targeted DNA sequencing, we determined the copy number and genetic variants of C4 in 2,290 well-characterized Scandinavian patients with SLE, primary SS, or myositis and 1,251 healthy controls. Results A prominent relationship was observed between C4A copy number and the presence of SSA/SSB autoantibodies, which was shared between the 3 diseases. The strongest association was detected in patients with autoantibodies against both SSA and SSB and 0 C4A copies when compared to healthy controls (odds ratio [OR] 18.0 [95% confidence interval (95% CI) 10.2-33.3]), whereas a weaker association was seen in patients without SSA/SSB autoantibodies (OR 3.1 [95% CI 1.7-5.5]). The copy number of C4 correlated positively with C4 plasma levels. Further, a common loss-of-function variant in C4A leading to reduced plasma C4 was more prevalent in SLE patients with a low copy number of C4A. Functionally, we showed that absence of C4A reduced the individuals capacity to deposit C4b on immune complexes. Conclusion We show that a low C4A copy number is more strongly associated with the autoantibody repertoire than with the clinically defined disease entities. These findings may have implications for understanding the etiopathogenetic mechanisms of systemic inflammatory autoimmune diseases and for patient stratification when taking the genetic profile into account.
