[Robert Koch as a young rural doctor in Brandenburg and the Poznan region (1868-1880)]

The bacteriologist and Nobel Prize winner Robert Koch (1843-1910) is one of the most important and best-known scientists in German history. Many people associate him not only with the institute named after him (today the Robert Koch Institute is Germany's National Public Health Institute), but above all, with his work as a "microbe hunter". Koch achieved world fame with the discovery of the tuberculosis pathogen in 1882. To research and combat infectious diseases, he undertook expeditions to foreign countries. This article deals with a lesser-known episode in Robert Koch's life - his years as a young rural doctor in the then Prussian provinces of Brandenburg and Posen. After a chronological description of Robert Koch's "wandering years", the focus is directed to today's culture of remembrance. The question is discussed in which way, if at all, the memory of Robert Koch is maintained at the authentic places.

[Kurt Huldschinsky: A pioneer in the struggle against rickets]

Kurt Huldschinsky (1883-1940) was a German pediatrician who was one of the international leaders in the field of rickets research between the two world wars. After his medical studies, he served at the Kaiserin-Auguste-Victoria-Haus in Berlin and at the University Children's Hospital in Vienna, among other places. After World War I, he worked with the famous orthopedist Konrad Biesalski at the Oskar-Helene-Heim for the healing and education of frail children in Berlin. Here he was the first to prove that exposure to ultraviolet (UV) radiation from mercury vapor lamps ("artificial sunlight") could cure rickets in young children, which is mostly caused by vitamin D deficiency. He published his discovery in this journal - the Deutsche Medizinische Wochenschrift [German Medical Weekly] - in 1919. For this groundbreaking scientific achievement and his further research into the prevention and treatment of rickets, Huldschinsky was awarded the Otto Heubner Prize of the German Association of Pediatrics in 1926. He was even nominated for the Nobel Prize in Medicine. As a Jew, however, he had to flee Germany from the National Socialists in 1933/34. Together with his wife and daughter, he emigrated to Egypt, where he died in Alexandria on October 31, 1940. As Huldschinsky was for many decades almost forgotten, this article recalls the life and work of a meritorious physician and scientist.

Better air but not for all? Changes in second-hand smoke exposure at workplaces in 29 European countries over 10 years

BACKGROUND

As the largest study of its kind to date, this article aims to describe the scope, trends over time, socio-demographic risk groups and the association with different progressive regulations relating to workplace second-hand smoke (SHS) exposure in 29 European countries during a period of high regulatory action.

METHODS

Three waves of the European Working Conditions Surveys (2005, 2010 and 2015) were evaluated, including a total of 95 718 workers. The samples are representative for all employed residents of the 29 countries included. All interviews were conducted face-to-face at respondents' homes (computer-assisted personal interviews). SHS exposure among the overall working population of 29 countries-including smokers-was examined. Workplace regimes were grouped corresponding to the sub-scale 'workplace' as used in the Tobacco Control Scale.

RESULTS

Between 2005 and 2015, SHS exposure in the European countries declined from around 19.0% (95% CI 16.1-22.0) to 9.9% (8.3-11.5). High SHS-exposure was reported by workers with the lowest level of education [11.5% (9.7-13.2)], among high-skilled manual labourers [14.3% (12.1-16.4)] and among those without a standard employment contract [11.2% (9.3-13.1)]. The highest exposure was reported by workers in the food service industry [19.7% (16.8-22.6)]. Countries with less workplace-related smoking prevention regulations were found to have the highest overall levels of exposure.

CONCLUSION

This multinational series of cross-sectional surveys on the trends in passive smoking in the workplace have shown that countries with more comprehensive workplace smoking bans overall report lower levels of SHS exposure among their work force as compared with slow progressing countries.

[Rahel Hirsch (1870-1953): A Tribute For The 150th Birthday Of The First Female Professor Of Medicine In Germany]

Rahel Hirsch, whose 150^th birthday was celebrated on 15 September 2020, is one of the female pioneers of medicine in Germany. Since it was not yet possible for women to study medicine in Germany at the end of the 19^th century, she initially worked as a teacher. In 1898 she went to Switzerland to study medicine, graduating in Strasbourg in 1903. From 1903 to 1919 she worked in the 2^nd Medical Clinic of the Berlin Charité hospital. Due to her scientific achievements, she was the first female medical doctor in Prussia to be awarded the title of professor in 1913. Her early investigations into the permeability of the intestinal mucosa for large corpuscular particles and their renal elimination were initially met with rejection and ignorance. It took more than half a century until the phenomena she discovered found their way into the specialist literature as the "Hirsch effect". After the First World War, Rahel Hirsch worked mainly in her own practice. As a Jew during the dictatorship of the National Socialists, she was marginalised and increasingly endangered, and emigrated to England in 1938. There she lived in modest circumstances and died in London in 1953. Rahel Hirsch, who asserted herself in a male-dominated environment both as a doctor and as a scientist, is a suitable role model for those who work for more gender equality in medicine and society today.

Waterpipe Use among Adolescents in Germany: Prevalence, Associated Consumer Characteristics, and Trends (German Health Interview and Examination Survey for Children and Adolescents, KiGGS)

Waterpipe (WP) use is popular among youth worldwide, but epidemiological data from Germany are scarce. We aimed to describe prevalence rates of WP use (current, last 12 months, ever) and analysed correlates and trends among 11- to 17-year-olds in Germany. Analyses were based on data from the "German Health Interview and Examination Survey for Children and Adolescents" study during 2014-2017 (n = 6599). Changes in WP use prevalence compared with 2009-2012 were used to describe trends. Associations with sociodemographic characteristics and cigarette smoking were assessed with multivariable logistic regression models. Prevalence of current WP use among adolescents was 8.5% (95% confidence interval (CI) = 7.5-9.6), use in the last 12 months was 19.7% (95% CI = 18.3-21.2), and ever use was 25.8% (95% CI = 24.2-27.5). High prevalence rates were particularly found among 16-17-year-olds. During 2009-2012, these prevalence rates were 9.0%, 18.5%, and 26.1%, respectively. WP use was associated with older age, male sex, migration background, lower educational level, and current smoking status. Among current WP users, 66.2% (95% CI = 60.0-71.9) identified themselves as non-smokers, and 38.1% (95% CI = 32.5-44.0) had used WP ≥ three times in the last month. WP consumption is popular among German youth, and prevalence rates have not changed over time. Specific prevention strategies to reduce harmful WP consumption among youth should be implemented.

Smoking during pregnancy. Results of the cross-sectional KiGGS Wave 2 study and trends

Background

Maternal smoking during pregnancy represents a significant risk, increasing the adverse consequences for mothers and newborns. Different national targets have been developed in Germany to reduce smoking rates during pregnancy. To monitor the achievement of these goals, this study aims to assess social differences and temporal trends of smoking behaviour during pregnancy in mothers living in Germany.

Methods

Data of children aged 0 to 6 with valid information on maternal smoking habits during pregnancy were subtracted from German Health Interview and Examination Survey for Children and Adolescents (KiGGS)(KiGGS baseline 2003-2006, n = 6,525 and KiGGS wave 2 2014-2017, n = 4,838). The information on maternal smoking during pregnancy was recorded retrospectively as part of a self-administered written questionnaire. We estimated the prevalence of smoking in pregnancy and multivariable logistic regression models to assess the association with the age of the mother at the time the child was born, the socioeconomic status of the family and the migration background. In addition, to analyse trends over time, we compare the current data with the KiGGS baseline study.

Results

The prevalence of mothers who smoked during pregnancy decreased statistically significant from 19.9% (KiGGS baseline) to 10.9% (KiGGS wave 2). Younger mothers aged up to 24 years were more likely to smoke during pregnancy (OR 1.74; 95%CI 1.04-2.89), similar to those with intermediate (OR 5.52; 95%CI 2.90-10.48) or low socioeconomic status (OR 22.43; 95%CI 10.84-46.39), and those without (OR 4.18; 95%CI 2.27-7.70) or with one-sided migration background (OR 2.47; 95%CI 1.26-4.84), in comparison to the groups of reference.

Conclusions

Our findings, present the reduction of smoking prevalence during pregnancy, recognising the effectiveness of the tobacco control programs in Germany. However, more emphasis on the prevention strategies for young and socially disadvantaged women are still required.

Key messages

Smoking prevalence during pregnancy has decreased in Germany over time, though still represents a challenge for public health and tobacco control. The prevention strategies should reduce the social breach, to extend the benefit among women and their offspring.

Individual and interpersonal correlates of cardiorespiratory fitness in adults - Findings from the German Health Interview and Examination Survey

Cardiorespiratory fitness (CRF) is an established predictor of adverse health outcomes. The aim of this study is to investigate potential behavioral, interpersonal and socioeconomic correlates of CRF among men and women living in Germany using data from a population-based nationwide cross-sectional study. 1,439 men and 1,486 women aged 18-64 participated in the German Health Interview and Examination Survey (2008-2011) and completed a standardized sub-maximal cycle ergometer test. Maximal oxygen consumption ([Formula: see text]) in ml·min-1·kg-1 was estimated. Mean values of VO2max for various anthropometric, behavioral, interpersonal, and sociodemographic variables were estimated. Linear regression analyses using multiple imputations technique for missing values was performed to analyze the influence of potential correlates on CRF. Women with high alcohol consumption had higher [Formula: see text], (β = 2.20; 95% CI 0.98 to 3.42) than women with low alcohol consumption and women with high occupational status had higher [Formula: see text] (β = 1.83; 95% CI 0.21 to 3.44) in comparison to women with low occupational status. Among men, high fruit intake (β = 1.52; 95% CI 0.63 to 2.40), compared to low or medium fruit intake and performing at least 2.5 hours of total PA per week (β = 2.19; 95% CI 1.11 to 3.28), compared to less than 2.5 hours was associated with higher [Formula: see text]. Among both men and women, lower body mass index, lower waist circumference and higher levels of physical exercise were considerably associated with higher [Formula: see text]. Among women, those in higher age groups showed a considerably lower level of [Formula: see text] compared with those aged 18-24. Furthermore, mean estimated [Formula: see text] was higher among men (36.5; 95% CI 36.0 to 37.0) than among women (30.3; 95% CI 29.8 to 30.7). Despite the cross-sectional nature of the current study, we conclude that several behavioral, anthropometric, and sociodemographic factors are associated with CRF in the general adult population in Germany. These results can provide evidence to tailor prevention measures according to the needs of specific subgroups.

["Medicine is a social science" - the 200th birthday of Salomon Neumann]

Salomon Neumann (1819-1908) is one of the outstanding representatives of 19th century social medicine. As a medical reformer, statistician and city councilor, he made a significant contribution to improving social and hygienic conditions in Berlin. His most famous work was published in 1847 under the title "Die oeffentliche Gesundheitspflege und das Eigenthum" [Public Health and Property]. From 1859 to 1905, Neumann was active in the Berlin City Council for the improvement of the living conditions of the population. He was involved in the construction of municipal hospitals, supported the modernisation of sewage disposal, organised the Berlin censuses of 1861 and 1864 and was active in the field of health and social statistics. Not only was Neumann exposed to anti-Semitic reprisals during his lifetime, a foundation he founded to promote the science of Judaism was dissolved by the National Socialists in 1940. On the occasion of his 200th birthday, this article commemorates the life and work of the democratically minded and socially committed doctor and health politician. Salomon Neumann has rendered great services to social medicine in Germany.

Educational differences in the prevalence of behavioural risk factors in Germany and the EU - Results from the European Health Interview Survey (EHIS) 2

This article examines educational differences in the prevalence of behavioural risk factors among adults and compares the results for Germany with the average from the European Union (EU). Data were derived from the second wave of the European Health Interview Survey, which took place between 2013 and 2015 (EHIS 2). Analyses were conducted using a regression-based calculation of relative and absolute educational differences in the prevalence of behavioural risk factors, based on self-reported data from women and men aged between 25 and 69 (n=217,215). Current smoking, obesity, physical activity lasting less than 150 minutes per week, heavy episodic drinking and non-daily fruit or vegetable intake are more prevalent among people with a low education level than those with a high education level. This applies to Germany as well as the EU average. Overall, the relative educational differences identified for these risk factors place Germany in the mid-range compared to the EU average. However, relative educational differences in current smoking and heavy episodic drinking are more manifest among women in Germany than the EU average, with the same applying to low physical activity among men. In contrast, relative educational differences in non-daily fruit or vegetable intake are less pronounced among women and men in Germany than the average across the EU. Increased efforts are needed in various policy fields to improve the structural conditions underlying health behaviour, particularly for socially disadvantaged groups, and increase health equity.

30 years after the fall of the Berlin Wall: Regional health differences in Germany

Following the fall of the Berlin Wall in November 1989, considerable effort was made to bring the living conditions and levels of social participation in the former East German federal states into line with the former West German federal states. As a result, differences in health between the East and the West diminished significantly, in many cases as early as the 1990s, examples being life expectancy and cardiovascular mortality. In regard to health behaviour, the overall tendency has also clearly been one of convergence. Thus, only very small differences can be observed today, for example in the use of tobacco or in the prevalence of obesity. Yet the results also highlight the insufficiency of regarding the remaining differences as a simple comparison between East and West. Instead, the focus should shift towards smaller-scale approaches that take regional differences in living conditions into account.

The health situation of children and adolescents with migration background in Germany

Introduction

Although more than one third of minors living in Germany have a migration background (MB), valid data on the health of this population are still lacking. The German Health Interview and Examination Survey for Children and Adolescents in Germany (KiGGS wave 2, 2014-2017) provides population-based data to make reliable statements on the health of adolescents with and without MB.

Methods

Survey data from KiGGS wave 2 are used to describe the general health status, mental health and the prevalence of allergic diseases in 3-to 17-year-old children and adolescents (n = 13,568). To determine overweight, body height and weight are measured (n = 3,463). In addition to MB (without/one-sided/two-sided), the socio-economic status (SES) and the length of stay of the parents in Germany are taken into account.

Results

Children and adolescents with two-sided MB show a physician-diagnosed atopic dermatitis (3.5%vs.6.9%) and attention deficit hyperactivity disorder (ADHD) (1.5%vs.5.1%) less frequently than their peers without MB, but more often a moderate or poor general health status (6.1%vs.3.9%). Adolescents with two-sided MB are also more often affected by overweight than those without MB (22.1%vs.12.2%). If only participants with MB are considered, their health situation is often associated with the SES and partly also with the length of stay of the parents.

Discussion

Health differences between children and adolescents with and without MB vary by the observed indicator. The heterogeneity of children and adolescents with MB, which can be partly determined by the SES or the length of stay of the parents, should be considered in target-group-specific interventions.

Main messages

The vast majority of children and adolescents in Germany grow up healthy and a MB is not per se associated with a poorer health status. Our results suggest that considering MB as the sole determinant of health to reflect the impact of migration on health is insufficient.

Key messages

Migration background is not per se associated with a poorer health status. Socioeconomic status and parents’ length of stay are derminants associated with poorer health outcomes among children and adolescents with migration background.

[Effects of poverty for health and health behavior of children and adolescents : Results from KiGGS Wave 2]

INTRODUCTION

Differences in the health status and health behavior of children and adolescents are analyzed, taking the income situation of the family into account.

METHOD

The data is based on the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-2017). Health outcomes are the subjective health, chronic health limitations, mental disorders, ADHD, consumption of fresh fruit, consumption of sugary soft drinks, physical activity, sports activity during leisure time, overweight, and obesity. The income situation is recorded using the equivalized household income.

RESULTS

Poor children and adolescents are more likely to have health problems than their peers from the middle- and, especially, the high-income group; their health behavior is less favorable. The biggest relative income-related differences are found in subjective health. With statistical control for parental education and occupational status, income-related differences in health status remain consistent while being significantly reduced for health behavior.

DISCUSSION

The results confirm that low family income has a significant impact on the health of children and adolescents. Partly, this also applies to their health behavior, whereby the observed differences between the income groups can be attributed mainly to parental education and occupational status. This shows once again that children and adolescents growing up in poverty should be a key target group for prevention and health promotion.

[Time trends of occupational differences in smoking behaviour of employed men and women in Germany : Results of the 1999-2013 microcensus]

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.

[Differences in subjective health, mental health, and health behavior among 11- to 17-year-olds at secondary schools in Germany : Results of the German health interview and examination survey for children and adolescents: first follow-up (KiGGS Wave 1)]

BACKGROUND

Social inequalities in health can already be found among children and adolescents to the disadvantage of socially deprived population groups. This paper aims to detect, whether differences in subjective health, mental health and health behavior among young people are due to the secondary school type attended and whether these associations exist independently of the family's socioeconomic position (SEP).

METHODS

The data basis was the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1, 2009-2012). Data of 11- to 17-year-old girls and boys (n = 4665) who attend different types of secondary schools in Germany were analyzed. The dependent variables were self-rated health, findings of the Strengths and Difficulties Questionnaire (SDQ) for the detection of psychological abnormalities, as well as self-reported information regarding leisure sport, tobacco, and alcohol consumption. Prevalence and odds ratios (ORs) based on logistic regressions are shown.

RESULTS

For the majority of the examined indicators, it can be shown that adolescents in lower secondary schools are more likely to report worse self-rated health and mental problems and engage in unhealthy behavior than peers in grammar schools ("Gymnasium"). The differences decrease after controlling for family's SEP but mostly remain statistically significant. Adolescents who don't attend grammar schools are most strongly disadvantaged in terms of inattention/hyperactivity for both gender (OR: 2.29 [1.70-3.08]), smoking among girls (2.91 [1.85-4.57]) and physical inactivity (no leisure sport) among boys (OR: 2.71 [1.85-3.95]).

DISCUSSION

Unequal health opportunities should be viewed in relation to people's living conditions. For adolescents, school constitutes an important setting for learning, experience, and health. The results indicate divergent needs of school-based health promotion and prevention regarding differences among gender and type of school.

[Trends in smoking among adults in Germany : Evidence from seven population-based health surveys from 1991-2015]

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.

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 educational inequalities in smoking among adolescents in Germany : Evidence from four population-based studies]

BACKGROUND

In Germany, smoking prevalence among adolescents has significantly declined since the early 2000s. However, data show that adolescent smoking rates considerably differ between different types of secondary schools. The aim of our study was to examine how educational inequalities in adolescent smoking behaviour have developed over time.

METHODS

Data were used from four population-based studies (each consisting of repeated cross-sectional surveys from 2001-2015): the representative surveys of the Federal Centre for Health Education, the German Health Interview and Examination Survey for Children and Adolescents, the Health Behaviour in School-aged Children Study, and the European School Survey Project on Alcohol and Other Drugs. Each study comprised different age groups (within the age range of 11-17 years) and used different smoking measures. Adolescents' educational status was based on the attended type of secondary school. Absolute and relative educational inequalities were presented as prevalence differences and prevalence ratios, respectively.

RESULTS

Despite methodical differences, all four studies similarly reveal that adolescent smoking rates have significantly declined in all educational groups. However, lower smoking rates among secondary school students attending higher educational tracks could be observed. While absolute educational inequalities tended to decrease over time, relative inequalities between educational groups remained rather stable or even increased.

DISCUSSION

Declining adolescent smoking rates suggest that smoking may have lost some of its attractiveness for young people. Our findings further emphasize the importance of tobacco control measures such as raising cigarette taxes, smoking bans, and increasing minimum legal age for tobacco purchase. As relative educational inequalities in adolescent smoking rates did not diminish over time, setting- and target group-specific interventions should focus more on students in middle and lower secondary school tracks.

Health inequalities among children and adolescents in Germany. Developments over time and trends from the KiGGS study

This study examines the extent to which health inequalities among children and adolescents in Germany have developed over the past decade. The analyses are based on data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), which are representative of the 0- to 17-year-old population in Germany. The KiGGS data were collected in three waves: the KiGGS baseline study (2003-2006), KiGGS Wave 1 (2009-2012) and KiGGS Wave 2 (2014-2017). Prevalences of five health outcomes are considered: general health, mental health problems, physical activity, the consumption of sugary soft drinks, and smoking. Moreover, it defines health inequalities in relation to differences in the socioeconomic status of the family (SES), an index derived from the parents’ level of education, occupation and income, and considers both absolute and relative health inequalities. In order to do so, the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) were calculated using linear probability or log-binomial models. Significant inequalities were identified to the detriment of young people from families with a low SES. These inequalities were particularly pronounced in the KiGGS Wave 2 data with regard to general health and the consumption of sugary soft drinks. Additionally, evidence from trend analyses for these two outcomes suggests that relative inequalities have increased. However, absolute inequalities decreased during the same period, and this also applies to smoking. The persistently high and, in some cases, widened levels of health inequalities indicate that adolescents from families with a low SES do not benefit to the same extent from disease prevention and health promotion measures for children and adolescents as young people from families with a higher SES.

Intergenerational Educational Pathways and Self-Rated Health in Adolescence and Young Adulthood: Results of the German KiGGS Cohort

Health differences in social mobility are often analysed by income differences or different occupational positions. However, in early adulthood many young people still have very diffuse income situations and are not always fully integrated into the labour market despite many having finished school. This article focusses on the link between intergenerational educational pathways and self-rated health (SRH) among young adults considering their SRH in adolescence. The data source used is the German KiGGS cohort study. The analysis sample comprises 2175 young people at baseline (t0: 2003⁻2006 age 14⁻17) and first follow-up (t1: 2009⁻2012 age 19⁻24). Combining parent's and young people's highest school degree, the data can trace patterns of intergenerational educational pathways (constant high level of education, upward mobility, downward mobility, constant low level of education). Young people's SRH was recorded at t0 and t1. During adolescence and young adulthood, participants were less likely to report poor SRH if they had a constant high intergenerational education or if they were upwardly mobile. The differences were particularly striking among young adults: average marginal effects (AME) for poor SRH showed much higher risk among downwardly mobile compared to peers with an intergenerational constant high education (AME: 0.175 [0.099; 0.251]), while the upwardly mobile had a significantly lower risk for less than good SRH than peers with an intergenerational constant low level of education (AME: -0.058 [-0.113; -0.004]). In the context of great societal demands and personal developmental needs, educational differences in health tend to increase in young adulthood. Public Health should pay more attention to educational and health inequalities in young adulthood.

Socioeconomic Inequalities in the Rise of Adult Obesity: A Time-Trend Analysis of National Examination Data from Germany, 1990-2011

OBJECTIVE

Despite extensive study of the obesity epidemic, research on whether obesity has risen faster in lower or in higher socioeconomic groups is inconsistent. This study examined secular trends in obesity prevalence by socioeconomic position and the resulting obesity inequalities in the German adult population.

METHODS

Data were drawn from three national examination surveys conducted in 1990-1992, 1997-1999 and 2008-2011 (n = 18,541; age range: 25-69 years). Obesity was defined by a body mass index ≥30 kg/m2 using standardised measurements of body height and weight. Education and equivalised household disposable income were used as indicators of socioeconomic position. Time trends in socioeconomic inequalities in obesity were examined using linear probability and log-binomial regression models.

RESULTS

In each survey period, the highest socioeconomic groups had the lowest prevalence of obesity. The low and medium socioeconomic groups showed increases in obesity prevalence, whereas no such trend was observed in the high socioeconomic groups. Absolute inequalities in obesity by income increased by an average of 0.53 percentage points per year (95% confidence interval [CI] 0.01-1.05, p = 0.047) among men and 0.47 percentage points per year (95% CI 0.05-0.90, p = 0.029) among women. Absolute inequalities in obesity by education increased on average by 0.64 percentage points per year (95% CI 0.19-1.08, p = 0.005) among women but not among men (0.33 percentage points, 95% CI -0.27 to 0.92, p = 0.283).

CONCLUSIONS

These findings suggest a widening obesity gap between the top and the bottom of the socioeconomic spectrum. This has the potential to have adverse consequences for population health and health inequalities in coming decades. Interventions that are effective in preventing and reducing obesity in socially disadvantaged groups are needed.

Oral health behaviour of children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

Oral health behaviour plays a key role in the prevention of caries and periodontitis. This article describes the prevalence, determinants and trends of tooth brushing frequency and utilization of dental check-ups. The analyses are based on the data from the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-2017). The results show that around 80% of children and adolescents meet the recommended tooth brushing frequency and utilization of dental check-ups. Around one fifth of children and adolescents do not meet the recommendations. 14- to 17-year-old adolescents, as well as those with low socioeconomic status and a migration background are groups which are particularly at risk. Compared to the KiGGS baseline study (2003-2006), tooth brushing frequency and utilization of dental check-ups has improved. While this positive development is apparent for nearly all the population groups analysed, the same risk groups that were identified by the baseline study are also evident in the KiGGS Wave 2 results. Targeted measures directed at specific target groups to promote oral health behaviour at younger ages should therefore be maintained and expanded, respectively.

Utilization of early detection examinations by children in Germany. Results of the cross-sectional KiGGS Wave 2 study

Examinations for early detection of diseases (called U-Untersuchungen in Germany) are among the most important prevention measures at childhood age. According to KiGGS Wave 2 data, participation rates are over 95% for most of these examinations. 99.7% and 99.6% of children, respectively, who had reached the recommended age for these examinations participated in the U1 and U2 examinations, 98.0% and 98.1%, respectively, the U8 and U9 examinations. Participation rates for children from families with low socioeconomic status and those with a two-sided migration background are slightly lower. A comparison with previous KiGGS waves shows that the utilization of early detection examinations has increased significantly over the last ten years. During this time, social differences which were previously pronounced have decreased.

Social differences in the utilization of medical services by children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study

Data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) enable conclusions about the utilization of outpatient and inpatient medical services by children and adolescents accounting the family's socioeconomic status (SES). Results from the second follow-up to the KiGGS survey (KiGGS Wave 2), which covers the years 2014 to 2017, clearly demonstrate that children and adolescents from families with a low SES visit specialists in general medicine, gynaecologists and psychiatrists, as well as child and adolescent psychiatrists, psychotherapists and psychologists more frequently. In contrast, children and adolescents from families with a high SES visit paediatric, dermatological, dental and orthodontic practices more often. No statistically significant differences between the status groups with regard to the utilization of outpatient medical services in hospitals were identified. However, children and adolescents from the low status group received inpatient hospital treatment more frequently and, on average, spent more nights in hospital. These results reflect status-specific differences both in disease prevalence and care, as well as in patterns related to the utilization of medical services.

Social inequalities in health of children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study

The close link between socioeconomic status (SES) and health can already be observed in childhood and adolescence. Although the vast majority of children and adolescents grow up healthily in Germany, social inequalities in health exist. The results of the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2) demonstrate that children and adolescents with a low SES have a poorer level of general health and face health constraints more frequently than their peers with a higher SES. Social inequalities in mental health are significantly more profound than in the 12-month prevalence of bronchial asthma and allergic rhinitis. The odds of being affected by mental health problems or attention-deficit/hyperactivity disorder (ADHD) were 2.8 to 4.4 times higher for children and adolescents with a low SES compared to their peers with a high SES. Therefore, in order to enable all children and adolescents to grow up healthily, health promotion and disease prevention measures need to be put in place early in a child's life and need to be tailored to the needs of particular target groups.

ADHD in children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

Attention deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders in childhood and adolescence and is associated with functional, psychosocial and cognitive impairment. As part of the second wave of the German Health Interview and Examination Survey for Children and Adolescents (2014-2017), parents of children and adolescents aged between 3 and 17 years reported whether their child was diagnosed with ADHD by a physician or psychologist. Overall, 4.4% of children and adolescents have been diagnosed with ADHD in Germany. In comparison, the KiGGS baseline study (2003-2006) showed a reduction of lifetime ADHD diagnoses of almost one percentage point over a period of ten years. The reduction of parent-reported ADHD diagnoses primarily occurred among 3- to 8-year old children and boys. The results are discussed in terms of health promotion and the introduction of health care measures.

Tobacco and alcohol use among 11- to 17-year-olds in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

Tobacco and alcohol use are among the leading preventable risk factors associated with premature mortality and a variety of diseases that have long-term effects. Although tobacco and alcohol use among adults is widespread in Germany, there is a trend towards lower levels of consumption. The foundations for health-related behaviour in adulthood are set at an early age: young people who use alcohol and tobacco also tend to do so regularly when they reach adulthood. With this in mind, health policies should focus on preventing young people from smoking, and encouraging them to adopt a responsible, low-risk approach to alcohol. This article analyses patterns of tobacco and alcohol use among children and adolescents (aged between 11 and 17 years). It describes the prevalences of tobacco and alcohol use, as well as trends and correlates. The data used in this article was sourced from the second follow-up to the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2). The survey's results show that 7.2% of 11- to 17-year-old children and adolescents smoke at least occasionally, with 3.7% doing so daily. The survey also demonstrates that a good half (51.0%) of 11- to 17-year-olds have ever drunk alcohol; at-risk drinking was prevalent among 12.1%, and heavy episodic drinking among 7.0%. The consumption of tobacco and alcohol increases considerably with age. Patterns of at-risk drinking and heavy episodic drinking show gender-associated differences: While more girls than boys practice at-risk drinking, more boys than girls practice heavy episodic drinking. Nevertheless, the KiGGS survey waves demonstrate a highly significant trend towards a decline in tobacco use (KiGGS baseline study 21.4%, KiGGS Wave 1 12.4%). The proportion of 11- to 17-year-olds who have ever drunk alcohol is also declining (KiGGS baseline study 63.9%, KiGGS Wave 1 55.6%). The proportions of at-risk drinking (KiGGS Wave 1 16.5%) and heavy episodic drinking (KiGGS Wave 1 12.0%) decreased as well. The results presented here are in line with findings from other studies that have surveyed adolescent tobacco and alcohol use in Germany, and they underscore the success of preventive measures.

The subjective health of adults in Germany

The term 'subjective health' reflects not only existing illnesses and health complaints, but particularly emphasizes the personal well-being. Studies often collect data on subjective health by asking participants to provide self-assessments of their general state of health. This was also the case with GEDA 2014/2015-EHIS, which employed the internationally renowned Minimum European Health Module (MEHM) as part of the study. Its results demonstrate that 68.2% of adults in Germany rate their general health as very good or good, with the remaining 31.8% rating it as fair, poor or very poor. The proportion of women who rate their general health as very good or good is slightly lower than the proportion of men who do so (66.6% compared to 69.9%). With increasing age, women and men view the condition of their general health as worsening. The study also identified educational differences which showed that men and women with low levels of education tend to rate their health worse compared to self-assessments provided by women and men with higher levels of education, and in some cases also regional differences.

Adult exposure to passive smoking in Germany

Passive smoking is associated with the same consequences for health as smoking, albeit to a lesser extent. Various legislative measures have been put in place in Germany to lower exposure to passive smoking. According to data from GEDA 2014/2015-EHIS, 11.3% of non-smoking adults are regularly exposed to passive smoking in enclosed spaces, this is particularly the case with young adults. Non-smoking women who are regularly exposed to passive smoking usually come into contact with passive smoking when they are together with friends and acquaintances (51.2%). Non-smoking men most frequently face passive smoking in the work place (56.1%). People with a high level of education are much less frequently exposed to passive smoking than those with medium to lower levels of education. Action still needs to be taken to protect people against the dangers linked to passive smoking.

Socioeconomic differences in the health behaviour of children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study

Childhood and adolescence are key determining stages for health behaviour in the life course. Frequently, health-related attitudes and patterns of behaviour that develop at young age are also maintained at adult age. As studies show, already during childhood and adolescence, patterns of health risk behaviour are more common in certain population groups. KiGGS Wave 2 results confirm that 3- to 17-year-old children and adolescents from families with low socioeconomic status (SES) eat a less healthy diet, do fewer sports and are more often overweight or obese than their peers from more affluent backgrounds. Whereas socioeconomic differences appear to have little effect on levels of alcohol consumption among 11- to 17 year-olds, girls and boys with low SES smoke more frequently than their peers with high SES. Prevention and health promotion encourage children and adolescents to adopt healthy lifestyles, and aim to drive structural changes to stimulate behaviour which promotes good health. Combining measures that target individual behaviour and a settings-based approach appears to be the most promising preventative approach to reduce health inequalities among young people. Due to the clear impacts of socioeconomic differences on health behaviour already at young age measures for disadvantaged children and adolescents and their living conditions should be given an even stronger focus in the future.

Post-millennial trends of socioeconomic inequalities in chronic illness among adults in Germany

Objective

Time trends in health inequalities have scarcely been studied in Germany as only few national data have been available. In this paper, we explore trends in socioeconomic inequalities in the prevalence of chronic illness using Germany-wide data from four cross-sectional health surveys conducted between 2003 and 2012 (n = 54,197; ages 25–69 years). We thereby expand a prior analysis on post-millennial inequality trends in behavioural risk factors by turning the focus to chronic illness as the outcome measure. The regression-based slope index of inequality (SII) and relative index of inequality (RII) were calculated to estimate the extent of absolute and relative socioeconomic inequalities in chronic illness, respectively.

Results

The results for men revealed a significant increase in the extent of socioeconomic inequalities in chronic illness between 2003 and 2012 on both the absolute and relative scales (SII₂₀₀₃ = 0.06, SII₂₀₁₂ = 0.17, p-trend = 0.013; RII₂₀₀₃ = 1.18, RII₂₀₁₂ = 1.57, p-trend = 0.013). In women, similar increases in socioeconomic inequalities in chronic illness were found (SII₂₀₀₃ = 0.05, SII₂₀₁₂ = 0.14, p-trend = 0.022; RII₂₀₀₃ = 1.14, RII₂₀₁₂ = 1.40, p-trend = 0.021). Whereas in men this trend was driven by an increasing prevalence of chronic illness in the low socioeconomic group, the trend in women was predominantly the result of a declining prevalence in the high socioeconomic group.

Smoking behaviour among children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

Smoking behaviour during adolescence is particularly important because the pattern of a person's tobacco consumption in later life usually is established in this period. According to recent data from KiGGS Wave 2, 7.4% of 11 to 17 year-old girls and 7.0% of boys of the same age smoke at least occasionally. The proportion of children and adolescents who smoke increases with age. Adolescents with high socioeconomic status smoke less frequently than their peers with medium or low socioeconomic status. Since the beginning of the first KiGGS study (2003-2006), the proportion of 11 to 17 year-olds who smoke fell from 21.4% to 12.4% (2009-2012) and has recently dropped to 7.2% (2014-2017). Despite considerable progress, however, there is still potential to improve tobacco prevention policy in Germany for example using taxation and advertising bans.

Smoking during pregnancy. Results of the cross-sectional KiGGS Wave 2 study and trends

Maternal smoking during pregnancy poses a significant risk to the development of unborn children. Data from KiGGS Wave 2 shows that 10.9% of mothers of 0 to 6 year-old children smoked during pregnancy. Mothers who were under 25 when giving birth smoked about two to three times more often than older mothers. Furthermore, there is a distinct social gradient in maternal smoking: a higher socioeconomic status is associated with a lower proportion of children with a mother who smoked during pregnancy. A comparison with data from the KiGGS baseline study shows that the proportion of mothers who smoked during pregnancy fell from to 19.9% to 10.9% between the two study periods. Thus, the KiGGS results are in line with those from the perinatal survey, which also found that the proportion of pregnant women who smoke has declined significantly since the mid-1990s.

Socioeconomic status and subjective social status measurement in KiGGS Wave 2

This article describes the method applied to measure socioeconomic status (SES) and subjective social status (SSS) in the current wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2), which was conducted over three years between 2014 and 2017. The composite multidimensional SES index was calculated as a sum of point scores for the parents' education level, occupational status and equivalised disposable income. SSS was assessed in the 11 to 17 year age group using a German version of the MacArthur Scale for children and adolescents. To demonstrate the use of both instruments, we present examples that highlight the association between SES and SSS with the general health of children and adolescents in the 3 to 17 and/or 11 to 17 age groups. Over 95% of parents rated the general health of their children as 'very good' or 'good'. However, the analyses clearly reveal that children and adolescents from families with low SES and SSS have poorer general health than their better-off peers. Even when mutually adjusted, both low SES and SSS are independently associated with poorer general health. In addition to the SES index, studies on the health of children and adolescents should therefore also consider SSS. In this way, additional aspects of the socioeconomic conditions of families can be taken into account.

The general health of children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

Data from KiGGS Wave 2 show that 95.7% of parents who participated in the survey rated the overall health of their 3 to 17 year-old children as very good or good. This proportion is higher than the figures identified by the KiGGS baseline study across all age groups. The proportion of children rated as in very good health is highest among 3 to 6 year-olds and decreases with age. Among 14 to 17 year-olds, the proportion of girls in very good health is well below the level found among boys. A pronounced social gradient is still clear from the data: the proportion of parents who assess the overall health of their children as very good or good rises with increasing social status. This highlights the need for strategies to reduce health inequalities that involve society as a whole, and the need for target group-specific measures in prevention and health promotion.

Health inequalities in Germany and in international comparison: trends and developments over time

Social epidemiological research has consistently demonstrated that people with a low socioeconomic status are particularly at risk of diseases, health complaints and functional limitations, and die at younger ages than those with a higher socioeconomic status. Greater stresses and strains in the workplace, family and living environment are under discussion as possible explanations. Health-related behaviours, psycho-social factors and personal resources, which are important in coping with everyday demands, certainly also play a role. From a public health and health policy perspective, reducing these health inequalities is an important goal. Insights into developments and trends in health inequalities over time can contribute towards highlighting new and emerging problems, and can thus help identify possible target groups and settings for relevant interventions. At the same time, these insights provide a basis upon which the success of policies and programmes that have already been implemented can be analysed and measured. Against this background, this review examines how health inequalities in Germany have developed over the last 20 to 30 years and places its findings within the context of the latest international research in this field.
