Socioeconomic inequalities in pandemic-induced psychosocial stress in different life domains among the working-age population.

BACKGROUND: Psychosocial stress is considered a risk factor for physical and mental ill-health. Evidence on socioeconomic inequalities with regard to the psychosocial consequences of the COVID-19 pandemic in Germany is still limited. We aimed to investigate how pandemic-induced psychosocial stress (PIPS) in different life domains differed between socioeconomic groups. METHODS: Data came from the German Corona-Monitoring nationwide study - wave 2 (RKI-SOEP-2, November 2021-February 2022). PIPS was assessed using 4-point Likert scales with reference to the following life domains: family, partnership, own financial situation, psychological well-being, leisure activity, social life and work/school situation. Responses were dichotomised into "not stressed/slightly stressed/rather stressed" (0) versus "highly stressed" (1). The sample was restricted to the working-age population in Germany (age = 18-67 years, n = 8,402). Prevalence estimates of high PIPS were calculated by sex, age, education and income. Adjusted prevalence ratios (PRs) were estimated using Poisson regression to investigate the association between education/income and PIPS; high education and income were the reference groups. RESULTS: The highest stress levels were reported in the domains social life and leisure activity. Women and younger participants reported high stress levels more frequently. The highest inequalities were found regarding people's own financial situation, and PIPS was higher in low vs. high income groups (PR 5.54, 95% CI 3.61-8.52). Inequalities were also found regarding partnerships with higher PIPS in low vs. high education groups (PR 1.68, 95% CI 1.13-2.49) - and psychological well-being with higher PIPS in low vs. high income groups (PR 1.52, 95% CI 1.14-2.04). CONCLUSION: Socioeconomic inequalities in PIPS were found for different life domains. Generally, psychosocial support and preventive interventions to help people cope with stress in a pandemic context should be target-group-specific, addressing the particular needs and circumstances of certain socioeconomic groups.

[Socioeconomic deprivation and premature mortality in Germany, 1998-2021 : An ecological study with what-if scenarios of inequality reduction]. / Sozioökonomische Deprivation und vorzeitige Sterblichkeit in Deutschland 1998­2021 : Eine ökologische Studie mit What-if-Szenarien der Ungleichheitsreduktion.

BACKGROUND: Earlier mortality in socioeconomically disadvantaged population groups represents an extreme manifestation of health inequity. This study examines the extent, time trends, and mitigation potentials of area-level socioeconomic inequalities in premature mortality in Germany. METHODS: Nationwide data from official cause-of-death statistics were linked at the district level with official population data and the German Index of Socioeconomic Deprivation (GISD). Age-standardized mortality rates before the age of 75 were calculated stratified by sex and deprivation quintile. A what-if analysis with counterfactual scenarios was applied to calculate how much lower premature mortality would be overall if socioeconomic mortality inequalities were reduced. RESULTS: Men and women in the highest deprivation quintile had a 43% and 33% higher risk of premature death, respectively, than those in the lowest deprivation quintile of the same age. Higher mortality rates with increasing deprivation were found for cardiovascular and cancer mortality, but also for other causes of death. Socioeconomic mortality inequalities had started to increase before the COVID-19 pandemic and further exacerbated in the first years of the pandemic. If all regions had the same mortality rate as those in the lowest deprivation quintile, premature mortality would be 13% lower overall. DISCUSSION: The widening gap in premature mortality between deprived and affluent regions emphasizes that creating equivalent living conditions across Germany is also an important field of action for reducing health inequity.

[Occupational differences of COVID-19 morbidity and mortality in Germany. An analysis of health insurance data from 3.17 million insured persons]. / Berufsbedingte Unterschiede bei COVID-19-Morbidität und -Mortalität in Deutschland. Eine Analyse von Krankenkassendaten von 3,17 Mio. Versicherten.

INTRODUCTION: During the COVID-19 pandemic, occupation was assumed to play a central role in the occurrence of infection and disease. For Germany, however, there are only a few studies that analyse occupational differences in risk of COVID-19, COVID-19-associated hospitalisation, and mortality. METHODS: The study uses longitudinal health insurance data from the research database of the Institute for Applied Health Research (InGef) with information on 3.17 million insured persons aged 18-67 years (1,488,452 women; 1,684,705 men). Outcomes (morbidity, hospitalisation, and mortality) were determined on the basis of submitted COVID-19 diagnoses between 1 January 2020 and 31 December 2021. Occupations were classified according to four groupings of the official German classification of occupations. In addition to cumulative incidences, relative risks (RR) were calculated - separately for men and women. RESULTS: There is an increased risk of disease in personal service occupations, especially in health care, compared to other occupations (RR for women 1.46; for men 1.30). The same applies to social and cultural service occupations (but only for women) and for manufacturing occupations (only for men). In addition, the risks for hospitalisation and mortality are increased for cleaning occupations and transport and logistics occupations (especially for men). For all three outcomes, the risks are higher in non-managerial occupations and differ by skill level (highest for unskilled jobs and lowest for expert positions). CONCLUSION: The study provides important findings on work- and gender-related differences in COVID-19 morbidity and mortality in Germany, which indicate starting points for structural infection protection measures.

Regional disparities in SARS-CoV-2 infections by labour market indicators: a spatial panel analysis using nationwide German data on notified infections.

BACKGROUND: Regional labour markets and their properties are named as potential reasons for regional variations in levels of SARS-CoV-2 infections rates, but empirical evidence is missing. METHODS: Using nationwide data on notified laboratory-confirmed SARS-CoV-2 infections, we calculated weekly age-standardised incidence rates (ASIRs) for working-age populations at the regional level of Germany's 400 districts. Data covered nearly 2 years (March 2020 till December 2021), including four main waves of the pandemic. For each of the pandemic waves, we investigated regional differences in weekly ASIRs according to three regional labour market indicators: (1) employment rate, (2) employment by sector, and (3) capacity to work from home. We use spatial panel regression analysis, which incorporates geospatial information and accounts for regional clustering of infections. RESULTS: For all four pandemic waves under study, we found that regions with higher proportions of people in employment had higher ASIRs and a steeper increase of infections during the waves. Further, the composition of the workforce mattered: rates were higher in regions with larger secondary sectors or if opportunities of working from home were comparatively low. Associations remained consistent after adjusting for potential confounders, including a proxy measure of regional vaccination progress. CONCLUSIONS: If further validated by studies using individual-level data, our study calls for increased intervention efforts to improve protective measures at the workplace, particularly among workers of the secondary sector with no opportunities to work from home. It also points to the necessity of strengthening work and employment as essential components of pandemic preparedness plans.

The impact of regional socioeconomic deprivation on the timing of HIV diagnosis: a cross-sectional study in Germany.

BACKGROUND: HIV infections which are diagnosed at advanced stages are associated with significantly poorer health outcomes. In Germany, the proportion of persons living with HIV who are diagnosed at later stages has remained continuously high. This study examined the impact of regional socioeconomic deprivation on the timing of HIV diagnosis. METHODS: We used data from the national statutory notification of newly diagnosed HIV infections between 2011 and 2018 with further information on the timing of diagnosis determined by the BED-Capture-ELISA test (BED-CEIA) and diagnosing physicians. Data on regional socioeconomic deprivation were derived from the German Index of Socioeconomic Deprivation (GISD). Outcome measures were a non-recent infection based on the BED-CEIA result or an infection at the stage of AIDS. The effect of socioeconomic deprivation on the timing of diagnosis was analysed using multivariable Poisson regression models with cluster-robust error variance. RESULTS: Overall, 67.5% (n = 10,810) of the persons were diagnosed with a non-recent infection and 15.2% (n = 2746) with AIDS. The proportions were higher among persons with heterosexual contact compared to men who have sex with men (MSM) (76.8% non-recent and 14.9% AIDS vs. 61.7% non-recent and 11.4% AIDS). MSM living in highly deprived regions in the countryside (< 100 k residents) were more likely to have a non-recent infection (aPR: 1.16, 95% CI: 1.05-1.28) as well as AIDS (aPR: 1.41, 95% CI: 1.08-1.85) at the time of diagnosis compared to MSM in less deprived regions in the countryside. No differences were observed among MSM from towns (100 k ≤ 1 million residents) or major cities (≥ 1 million residents), and no differences overall in the heterosexual transmission group. CONCLUSIONS: An effect of socioeconomic deprivation on the timing of HIV diagnosis was found only in MSM from countryside regions. We suggest that efforts in promoting HIV awareness and regular HIV testing are increased for heterosexual persons irrespective of socioeconomic background, and for MSM with a focus on those living in deprived regions in the countryside.

Socioeconomic differences in the reduction of face-to-face contacts in the first wave of the COVID-19 pandemic in Germany.

BACKGROUND: The COVID-19 pandemic has led to physical distancing measures to control the spread of SARS-CoV-2. Evidence on contact dynamics in different socioeconomic groups is still sparse. This study aimed to investigate the association of socioeconomic status with private and professional contact reductions in the first COVID-19 wave in Germany. METHODS: Data from two especially affected municipalities were derived from the population-based cross-sectional seroepidemiological CORONA-MONITORING lokal study (data collection May-July 2020). The study sample (n = 3,637) was restricted to working age (18-67 years). We calculated the association of educational and occupational status (low, medium, high) with self-reported private and professional contact reductions with respect to former contact levels in the first wave of the pandemic. Multivariate Poisson regressions were performed to estimate prevalence ratios (PR) adjusted for municipality, age, gender, country of birth, household size, contact levels before physical distancing measures, own infection status, contact to SARS-CoV-2 infected people and working remotely. RESULTS: The analyses showed significant differences in the initial level of private and professional contacts by educational and occupational status. Less private contact reductions with lower educational status (PR low vs. high = 0,79 [CI = 0.68-0.91], p = 0.002; PR medium vs. high = 0,93 [CI = 0.89-0.97], p = 0.001) and less professional contact reductions with lower educational status (PR low vs. high = 0,87 [CI = 0.70-1.07], p = 0.179; PR medium vs. high = 0,89 [CI = 0.83-0.95], p = 0.001) and lower occupational status (PR low vs. high = 0,62 [CI = 0.55-0.71], p < 0.001; PR medium vs. high = 0,82 [CI = 0.77-0.88], p < 0.001) were observed. CONCLUSIONS: Our results indicate disadvantages for groups with lower socioeconomic status in private and professional contact reductions in the first wave of the pandemic. This may be associated with the higher risk of infection among individuals in lower socioeconomic groups. Preventive measures that a) adequately explain the importance of contact restrictions with respect to varying living and working conditions and b) facilitate the implementation of these reductions especially in the occupational setting seem necessary to better protect structurally disadvantaged groups during epidemics.

Socioeconomic inequalities in primary-care and specialist physician visits: a systematic review.

BACKGROUND: Utilization of primary-care and specialist physicians seems to be associated differently with socioeconomic status (SES). This review aims to summarize and compare the evidence on socioeconomic inequalities in consulting primary-care or specialist physicians in the general adult population in high-income countries. METHODS: We carried out a systematic search across the most relevant databases (Web of Science, Medline) and included all studies, published since 2004, reporting associations between SES and utilization of primary-care and/or specialist physicians. In total, 57 studies fulfilled the eligibility criteria. RESULTS: Many studies found socioeconomic inequalities in physician utilization, but inequalities were more pronounced in visiting specialists than primary-care physicians. The results of the studies varied strongly according to the operationalization of utilization, namely whether a physician was visited (probability) or how often a physician was visited (frequency). For probabilities of visiting primary-care physicians predominantly no association with SES was found, but frequencies of visits were higher in the most disadvantaged. The most disadvantaged often had lower probabilities of visiting specialists, but in many studies no link was found between the number of visits and SES. CONCLUSION: This systematic review emphasizes that inequalities to the detriment of the most deprived is primarily a problem in the probability of visiting specialist physicians. Healthcare policy should focus first off on effective access to specialist physicians in order to tackle inequalities in healthcare. PROSPERO REGISTRATION NUMBER: CRD42019123222 .

[Social inequalities in the regional spread of SARS-CoV-2 infections]. / Soziale Ungleichheit in der regionalen Ausbreitung von SARS-CoV-2.

BACKGROUND AND OBJECTIVE: It has not been adequately answered whether the spread of SARS-CoV­2 is influenced by social and economic factors. Earlier studies generally looked at cumulative incidences up to the analysis date and did not take into account the development of the spread over time. This study therefore focuses on the regional dynamic of new infections and their relationship to socioeconomic factors. Based on the literature we describe the state of knowledge and present our own analyses of administrative data from Germany. METHODS: For this study, we examined regional progress data of reported COVID-19 cases for 401 cities and counties in Germany and associated them with socioeconomic characteristics of the areas. Age-standardized weekly incidence rates were calculated for the period from 3 February 2020 to 28 March 2021. Macroindicators were added from the INKAR database (e.g., income, employment rate, and crowding). RESULTS: While areas with higher incomes and lower poverty had higher incidences in the first and at the beginning of the second wave of the pandemic, they increased significantly in low-income regions from December 2020 on. Regions with a high proportion of gainfully employed people in general and especially those in the manufacturing sector had high incidences, especially in the second wave and at the beginning of the third wave. A low mean living space per inhabitant was related to higher incidence rates since November 2020. CONCLUSION: The regional temporal course of the pandemic correlates with social and economic indicators. A differentiated consideration of these differences could provide information on target group-specific protection and test strategies and help to identify social factors that generally favor infections.

Serology- and PCR-based cumulative incidence of SARS-CoV-2 infection in adults in a successfully contained early hotspot (CoMoLo study), Germany, May to June 2020.

Three months after a coronavirus disease (COVID-19) outbreak in Kupferzell, Germany, a population-based study (n = 2,203) found no RT-PCR-positives. IgG-ELISA seropositivity with positive virus neutralisation tests was 7.7% (95% confidence interval (CI): 6.5-9.1) and 4.3% with negative neutralisation tests. We estimate 12.0% (95% CI: 10.4-14.0%) infected adults (24.5% asymptomatic), six times more than notified. Full hotspot containment confirms the effectiveness of prompt protection measures. However, 88% naïve adults are still at high COVID-19 risk.

[Social Inequalities and COVID-19: Social-Epidemiological Perspectives on the Pandemic]. / Soziale Ungleichheit und COVID-19: Sozialepidemiologische Perspektiven auf die Pandemie.

The new Coronavirus Disease (COVID-19) hits specific population groups harder than others. However, social-epidemiological patterns of the pandemic which go beyond differences by age and gender have hardly been addressed in Germany. First reports from other western industrialised countries indicate that people living in socioeconomically deprived areas and people of color have an increased risk of severe COVID-19 progression and mortality. Social inequalities in the risk of infection due to different living and working conditions, and social inequalities in the susceptibility and risk factors for severe COVID-19, particularly in pre-existing medical conditions, might play an important role in explaining those findings. Such inequalities are well established for Germany, as well. It can therefore be assumed that also in Germany people with a lower socioeconomic status might be more affected during the further course of the pandemic. In addition, the interventions to contain the pandemic might have unequal social, economic and psychological impacts on different social groups. Hence, the COVID-19 pandemic has the overall potential to increase social and health inequalities. Social-epidemiological research into COVID-19 is therefore needed to advance measures of health protection and infection control in an evidence-based, targeted and socially equitable manner.

[Socioeconomic differences in health and need for care among the elderly]. / Sozioökonomische Unterschiede in der Gesundheit und Pflegebedürftigkeit älterer Menschen.

In view of the continuing increase in life expectancy, the question arises as to the state of health in which these years of gained life can be spent. The research findings on social differences in health and life expectancy suggest that this question has to be answered differently for different population groups. Even after the age of 65, persons with a low socioeconomic status are more likely to be affected by chronic illnesses and complaints, functional limitations of everyday activities, as well as impairments of well-being and health-related quality of life. With a significant proportion of people with low socioeconomic status still dying prematurely, the increase in lifetime that is observed for all population groups could increase the social gap in health in later life. This implies the challenge of giving special attention to the needs of socially disadvantaged groups in policies and programs aiming to improve the health of older people and preventing the need for care.

[Socioeconomic inequalities in health in later life]. / Soziale Ungleichheit und Gesundheit im höheren Lebensalter.

BACKGROUND: Socioeconomic differences in health and life expectancy are key issues for public health and health policy. In the course of demographic change, in addition to childhood, adolescence and middle adulthood, old age is increasingly becoming the focus of attention in research on health inequalities, with a special emphasis on the transition from working age to retirement. OBJECTIVE: How do health inequalities change in the transition from middle to older age and then to very old age? MATERIAL AND METHODS: This article reviews the studies available for Germany, supplemented with new analyses based on the German Health Update study and the German Socioeconomic Panel study. In order to set the findings in the context of international research on health inequalities in old age, selected studies from other countries and international comparative studies are additionally considered. RESULTS: Social differences in health and remaining life-expectancy also exist in older age, although to a slightly lesser extent than in middle age. There is evidence that as age progresses, health inequalities narrow in some health domains but there is also isolated evidence that health inequalities may widen with age. CONCLUSION: The existence of health inequalities in old age indicates that older people from disadvantaged social groups have a particular need for healthcare and support. This poses special challenges for the medical, nursing and psychosocial care system as well as for the social security systems.

Trends in Absolute and Relative Educational Inequalities in Adult Smoking Since the Early 2000s: The Case of Germany.

Introduction: Since the early 2000s, several tobacco control policies have been implemented in Germany. Current research is inconsistent about how strengthening tobacco control can affect social inequalities in smoking. This study examines whether educational inequalities in adult smoking have widened in Germany since 2003. Methods: Data were used from four cross-sectional national health surveys conducted between 2003 and 2012 (n = 54,197; age = 25-69 years). Participants who smoked daily or occasionally were classified as smokers. The regression-based Slope Index of Inequality and Relative Index of Inequality (RII) were calculated to estimate the extent of absolute and relative educational inequalities in smoking, respectively. Results: In each survey year, smoking was associated with lower education. Overall, crude and age-standardized smoking rates declined over time. Stratified by education, trends of declining smoking rates were observed only in the high and medium education groups, whereas no statistically significant trend was found in the low education group. Relative educational inequalities in smoking increased significantly in men (2003: RII=1.74, 95% confidence interval 1.46 to 2.07; 2012: RII = 2.25, 95% confidence interval 1.90 to 2.67; p-trend = .019). Absolute educational inequalities in smoking were not found to have changed significantly during the study period. Conclusions: In the course of declining smoking rates, educational inequalities in smoking persisted in both absolute and relative terms. In men, relative inequalities in smoking may even have widened within only 9 years. Tobacco control policies should not only be targeted at the entire population but also attempt to reduce social inequalities in smoking by focusing more on socially disadvantaged groups. Implications: Smoking is associated with lower education in most European countries and contributes to social inequalities in health. Since the beginning of the 2000s, Germany has implemented a variety of tobacco control policies to reduce smoking in the population. This study reveals that despite a general decline in adult smoking, educational inequalities in smoking have persisted and even widened in Germany since 2003. The findings emphasize that more targeted efforts are needed to tackle smoking-induced inequalities in health.

[Trends in smoking among adults in Germany : Evidence from seven population-based health surveys from 1991-2015]. / Zeitliche Trends beim Rauchverhalten Erwachsener in Deutschland : Ergebnisse sieben bundesweiter Gesundheitssurveys 1991­2015.

BACKGROUND: Despite decreasing smoking prevalence, tobacco use remains a key public health problem in Germany. For planning, managing, and evaluating tobacco control measures, regular data collection on smoking behavior in the population is essential. The aim of this article is to present trends in adult tobacco use since the early 1990s based on data from the health monitoring of the Robert Koch-Institute (RKI). METHODS: Analyses are based on data from 106,158 individuals aged 18 to 79 years, who participated in seven RKI health surveys from 1991-2015. Trends in tobacco consumption were analyzed using different indicators of smoking behavior, stratified by age, cohort, and gender. RESULTS: An overall falling smoking prevalence can be attributed primarily to a significant decline in the younger age groups since the early 2000s. Trend analysis by cohort reveals a declining prevalence for almost all cohorts over time from 1991-2015. Historically there has been is a sharp increase in the prevalence of women who have ever smoked between the 1930-1934 and 1950-1959 cohorts. The proportion of men who have ever smoked slightly decreased between the 1930-1934 and 1980-1984 cohorts. DISCUSSION: The shown overall decline happened concurrently with various tobacco prevention measures implemented during this period in Germany. If present trends related to continuous high smoking rates are sustained, it can be assumed that the tobacco consumption of the population will remain the source of adverse health outcomes. Accordingly, tobacco prevention measures and the promotion of smoking cessation in all age groups should be a public health priority.

[Time trends of occupational differences in smoking behaviour of employed men and women in Germany : Results of the 1999-2013 microcensus]. / Zeitliche Entwicklung berufsgruppenspezifischer Unterschiede im Rauchverhalten von erwerbstätigen Männern und Frauen in Deutschland : Ergebnisse des Mikrozensus 1999­2013.

BACKGROUND: Studies show that people with a low occupational status are more likely to smoke than those with a high occupational status. Against the background of a general decline in tobacco consumption, time trends of occupational differences in smoking behaviour of employed men and women in Germany were examined. METHODS: The analyses were based on the last five waves of the German microcensus that included questions about smoking (1999, 2003, 2005, 2009 and 2013), taking only employed men and women aged 18-64 years into account (n = 688,746). Information on occupational position was summarised using international classifications of occupation (ISEI-08 and ISCO-08). Raw and model-based standardized prevalence estimates of current smoking were calculated. RESULTS: Between 1999 and 2013, the proportion of smokers in the working population fell from 39.9 to 34.4% (men) and from 30.6 to 26.8% (women). Differences between occupational status groups increased significantly: while the prevalence of smoking among employees with high occupational status decreased, it remained largely stable in the low status group. In 2013, the occupations with the highest proportion of smokers were waste disposal workers, cleaning staff, unskilled workers, truck and bus drivers, salespeople and cashiers, and employees in the catering industry. CONCLUSION: Since the beginning of the 2000s, the prevalence of smoking in the working population has declined. The strengthened tobacco control policy - e. g. the establishment of smoke-free workplace laws - might have contributed to this trend. In the context of workplace health promotion, tobacco prevention and cessation measures should be targeted at those professions in which smoking is still particularly common.

Changing educational inequalities in sporting inactivity among adults in Germany: a trend study from 2003 to 2012.

BACKGROUND: Social inequalities in health can be explained in part by the social patterning of leisure-time physical activity, such as non-participation in sports. This study is the first to explore whether absolute and relative educational inequalities in sporting inactivity among adults have changed in Germany since the early 2000s. METHODS: Data from four cross-sectional national health surveys conducted in 2003 (n = 6890), 2009 (n = 16,418), 2010 (n = 17,145) and 2012 (n = 13,744) were analysed. The study population was aged 25-69 years in each survey. Sporting inactivity was defined as no sports participation during the preceding 3 months. The regression-based Slope Index of Inequality (SII) and Relative Index of Inequality (RII) were calculated to estimate the extent of absolute and relative educational inequalities in sporting inactivity, respectively. RESULTS: Sporting inactivity was consistently more prevalent in less-educated groups. The overall prevalence of sporting inactivity declined significantly over time. However, the decline was observed only in the high and medium education groups, while no change was observed in the low education group. Both absolute and relative educational inequalities in sporting inactivity were found to have widened significantly between 2003 (SII = 0.30, 95% CI = 0.25-0.35; RII = 2.08, 95% CI = 1.83-2.38) and 2012 (SII = 0.41, 95% CI = 0.37-0.45; RII = 3.44, 95% CI = 3.03-3.91). Interaction analysis showed that these increases in inequalities were larger in the younger population under the age of 50 than among the elderly. CONCLUSIONS: The findings suggest that the gap in sports participation between adults with high and low educational attainment has widened in both absolute and relative terms because of an increase in sports participation among the better educated. Health-enhancing physical activity interventions specifically targeted to less-educated younger adults are needed to prevent future increases in social inequalities in health.

[Social inequalities in the prevalence of chronic back pain among adults in Germany]. / Soziale Ungleichheit und chronische Rückenschmerzen bei Erwachsenen in Deutschland.

BACKGROUND: Back pain is a common cause for health care utilization and inability to work and associated with corresponding costs. The aim of the study was to investigate socioeconomic inequalities in chronic back pain in the adult general population. METHODS: The analyses were based on pooled data of three waves (2009, 2010, 2012) of the nationwide German Health Update (GEDA) study carried out by the Robert Koch Institute (n = 62,606 aged 18 years and older). Self-reported back pain symptoms persisting at least three months were used to determine lifetime and 12-month prevalence. For analyzing socioeconomic differences in the prevalence of chronic back pain, a multidimensional SES index and its three individual components - educational level, occupational status and income - were used. RESULTS: About every sixth man (17.1%) and every fourth woman (24.4%) reported chronic back pain in the past twelve months. With decreasing SES, the 12-month prevalence of chronic back pain increased (Relative Index of Inequality (RII) [95% CI], men = 2.29 [2.04-2,56], women=1.92 [1.76-2.09]). Similar results were observed for lifetime prevalence. For both men and women, educational level, occupational status and income each had independent effects on chronic back pain prevalence. CONCLUSION: In Germany, back pain is widely prevalent. Our finding that different aspects of SES are independently associated with chronic back pain prevalence is a challenge but also a chance for treatment and preventive strategies combining behavioral and setting-oriented measures.

[Socioeconomic differences in physical activity in the middle-aged working population: The role of education, occupation, and income]. / Sozioökonomische Unterschiede in der körperlich-sportlichen Aktivität von Erwerbstätigen im mittleren Lebensalter : Welche Rolle spielen Bildung, Beruf und Einkommen?

BACKGROUND: Regular physical activity has positive effects on health at all ages. This study aims to investigate how far physical activity and regular sports engagement, as a more specific type of physical activity, are associated with socioeconomic factors in the middle-aged working population. METHODS: Data were obtained from 21,699 working men and women aged between 30 and 64 years who participated in the 2009 and 2010 population-based national German Health Update (GEDA) surveys conducted by the Robert Koch Institute. Besides a multi-dimensional index of socioeconomic status (SES), three single dimensions of SES (education, occupation, and income) were used to analyse socioeconomic differences in total physical activity and regular sports engagement. RESULTS: While the prevalence of total physical activity increased with lower SES, the proportion of people with regular sports engagement decreased with lower SES. These associations remained after adjusting for age in men and women. After mutual adjustment of the three single socioeconomic dimensions, physical activity was independently associated with lower education and lower occupational status. Regular sports engagement was observed to be independently associated with higher education, higher occupational status, as well as higher income after mutual adjustment. CONCLUSIONS: This study demonstrates significant socioeconomic differences in physical and sports activity in the middle-aged working population. Education, occupation, and income show varying independent associations with physical activity behaviour. Such differences need to be considered when identifying target groups for health-enhancing physical activity interventions.

[Health literacy of adults in Germany: Findings from the German Health Update (GEDA) study]. / Gesundheitskompetenz von Erwachsenen in Deutschland : Ergebnisse der Studie "Gesundheit in Deutschland aktuell" (GEDA).

BACKGROUND: In today's information society, health literacy (HL) is considered important for health maintenance and disease management. In this context, dealing with health information is fundamental and requires different cognitive and social skills. OBJECTIVES: The aim of this study was to investigate the distribution of HL levels in the adult population of Germany, and to identify associations with health behaviours and health status. MATERIALS AND METHODS: The analyses were based on data from the German Health Update (GEDA) study, a cross-sectional survey of the German-speaking adult population of Germany, which was conducted from October 2013 to June 2014. Health literacy was assessed with the short form of the European Health Literacy Questionnaire (HLS EU-Q16), along with questions about socio-demographics, health behaviours, and health status. The HLS-EU-Q16 index could be calculated for 4845 respondents. RESULTS: According to the criteria of the HLS-EU-Q16, more than half of the adults had "adequate" HL (55.8 %). Every third person (31.9 %) had "problematic" and almost every eighth person (12.3 %) had "inadequate" HL. We found significant differences in HL by educational level, but no differences in HL by sex and age group. Certain health behaviours were positively associated with health literacy. A low HL level was associated with poorer physical and mental health. CONCLUSION: The results point to a need for action to improve HL in the adult population. The strengthening of health literacy should not solely aim at the promotion of individual skills, but also give high priority to the development of health-literate settings.

[Measuring subjective social status in health research with a German version of the MacArthur Scale]. / Messung des subjektiven sozialen Status in der Gesundheitsforschung mit einer deutschen Version der MacArthur Scale.

In health research, socio-economic status (SES) is traditionally assessed using objective indicators (education, occupation, income). For a couple of years, there has been a growing body of studies that additionally assess the subjective social status (SSS) of respondents, mostly using the MacArthur Scale. The aim of this study was to examine the construct validity of a German-language version of this instrument and to investigate whether SSS is associated with health over and above objective SES. Analyses were based on data from a population-based pilot study carried out within the 'German Health Update' (GEDA) study conducted by the Robert Koch Institute (n = 1,571; age: 18-79 years). SSS was measured with the MacArthur scale asking respondents to place themselves on a 10-rung "social ladder". The strongest correlations to SSS were found with measures of similar constructs such as a multidimensional index of objective SES, income level, occupational position and educational attainment (r = 0.32-0.60; p < 0.001). Weaker correlations were found between SSS and measures of dissimilar constructs such as social support, mental well-being, depressiveness, and body-mass-index (r = - 0.29-0.30; p < 0.001). Factor analysis did not show considerable loadings of SSS on factors of mental well-being and depressiveness. After adjusting for age, education, occupation, and income, lower SSS remained significantly associated with higher odds of adverse health (p < 0.05). The findings of this study provide support for the convergent and discriminant validity of the MacArthur Scale and indicate that self-perceptions of social disadvantage may have health implications beyond the impact of objective SES.
