[Prevalence of myocardial infarction and coronary heart disease in adults aged 40-79 years in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. / Prävalenz von Herzinfarkt und koronarer Herzkrankheit bei Erwachsenen im Alter von 40 bis 79 Jahren in Deutschland: Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

In the German Health Interview and Examination Survey for Adults (DEGS1), data on the prevalence of myocardial infarction and coronary heart disease were collected from 2008-2011 in a representative population-based sample of 5,901 adults aged 40-79 years. The results of DEGS1 were compared with the prevalence estimates from the German National Health Interview and Examination Survey 1998 (GNHIES98). The lifetime prevalence of myocardial infarction amongst 40-79 year olds in DEGS1 is 4.7 % (women 2.5 %; men 7 %). In comparison with GNHIES98 a small increase was observed in men, but not in women. The lifetime prevalence of coronary heart disease in adults aged 40-79 years in DEGS1 is 9.3 % (women 6.4 %; men 12.3 %). In comparison to GNHIES98 there is a slight reduction only in women. There is a significant inverse relationship between disease prevalence and socioeconomic status. The trend in prevalence of coronary heart disease is comparable with that in other high-income countries. Given a falling incidence of myocardial infarction and a decrease in the mortality rates due to coronary heart disease, the basically stable prevalence rates indicate a positive development in the field of cardiovascular prevention and therapy.

[Prevalence of stroke in adults aged 40 to 79 years in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. / Prävalenz des Schlaganfalls bei Erwachsenen im Alter von 40 bis 79 Jahren in Deutschland: Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

In the German Health Interview and Examination Survey (DEGS1), data on the prevalence of physician-diagnosed stroke were collected from 2008 to 2011 in a representative population-based sample of 5,901 adults aged 40-79 years. The stroke prevalence in DEGS1 was compared with prevalence estimates from the German National Health Interview and Examination Survey 1998 (GNHIES98). The lifetime prevalence of stroke in adults aged 40-79 years is 2.9 % (women: 2.5 %; men: 3.3 %). In both sexes, the prevalence increases continuously with age, up to 6.3 % in women and 8.1 % in men 70-79 years old. More pronounced in women than in men, the prevalence of stroke decreases with increasing socioeconomic status. Compared to GNHIES98, there is no evidence for a change in stroke prevalence over time. The prevalence of stroke in adults aged 40-79 years in Germany is comparable to prevalence estimates from other national and international studies. Further studies should examine the reasons behind stable prevalence rates, accounting for population ageing and changes in incidence, mortality and case fatality rates.

[Fruit and vegetable intake in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. / Obst- und Gemüsekonsum in Deutschland : Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

Until now, the recommendations of the German Nutrition Society on fruit and vegetable intake have not been reached by the majority of the population. In the first wave of the"German Health Interview and Examination Survey for Adults" (DEGS1), which was conducted from 2008 to 2011, food consumption was determined with a validated food frequency questionnaire in a representative random sample of the 18-79-year-old residential population in Germany (n=7116). The number of portions of fruit and vegetables consumed on average every day and the number of persons meeting the recommended five portions of fruit and vegetables per day were calculated. On average, women consume 3.1 and men 2.4 portions of fruit and vegetables per day. 15 % of women and 7 % of men reach the recommended quantity of five portions per day. Fruit intake increases in both men and women up to the age of 60- 69 years. 39 % of women and 25 % of men consume at least three portions of fruit and vegetables every day. The proportion of men and women who consume at least three portions every day tends to increase with rising social status. Although the intake of fruit has increased slightly compared to previous surveys, the percentage of persons who consume five portions of fruit and vegetables per day is still very low.

[Overweight and obesity in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS1)]. / Übergewicht und Adipositas in Deutschland: Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

The increase in overweight and obesity is a worldwide health problem. The first wave of the "German Health Interview and Examination Survey for Adults" (DEGS1), conducted from 2008 through 2011, provides current data about overweight and obesity among adults in Germany. Within DEGS1, a representative sample of the 18- to 79-year-old population was interviewed with regard to health relevant issues and physically examined (n = 7,116). From measurements of body height and weight, the body mass index (BMI) was calculated, which was used to define overweight (BMI ≥ 25 kg/m(2)) and obesity (BMI ≥ 30 kg/m(2)). Results are stratified for gender, age group, socioeconomic status and region and compared with results from the German National Health Interview and Examination Survey 1998 (GNHIES98) and the National Examination Surveys 1990/92. According to DEGS1, 67.1% of men and 53.0% of women are overweight. The prevalence of overweight has not changed compared to GNHIES98. The prevalence of obesity, however, has risen substantially, especially among men: in GNHIES98, 18.9% of men and 22.5% of women were obese, in DEGS1, these figures were 23.3% and 23.9%, respectively. The increase in obesity occurred especially among young adults. An English full-text version of this article is available at SpringerLink as supplemental.

[Prevalence of dyslipidemia among adults in Germany: results of the German Health Interview and Examination Survey for Adults (DEGS 1)]. / Verbreitung von Fettstoffwechselstörungen bei Erwachsenen in Deutschland: Ergebnisse der Studie zur Gesundheit Erwachsener in Deutschland (DEGS1).

Interview and laboratory data from the first wave of the German health interview and examination survey for adults (DEGS1) from 2008 to 2011 were used to provide current estimates of the prevalence of dyslipidemia which are representative of the population in Germany 18 to 79 years of age. A total of 56.6 % of men and 60.5 % of women 18 to 79 years have elevated serum total cholesterol concentrations in excess of the currently recommended threshold of 190 mg/dL; 17.9 % of men and 20.3 % of women have highly elevated total cholesterol concentrations ≥ 240 mg/dL. A total of 19.3 % of men and 3.6 % of women have high density lipoprotein cholesterol concentrations below 40 mg/dL. The overall prevalence of dyslipidemia (total cholesterol ≥ 190 mg/dL or medical diagnosis of dyslipidemia) is 64.5 % for men and 65.7 % for women. Of these, more than half of both men and women have previously undiagnosed dyslipidemia. Among persons with known dyslipidemia, 30.8% take lipid-lowering medication. Dyslipidemia is widely prevalent among adults in Germany. More in-depth analyses will examine time trends in the prevalence of dyslipidemia in Germany and in an international comparison.

Vascular aging in the young: New carotid stiffness centiles and association with general and abdominal obesity - The KIGGS cohort.

BACKGROUND AND AIMS: The evidence for an association between obesity and increased carotid intima-media thickness (CIMT) and carotid stiffness (CS) in the young has been limited by methodological challenges related to study populations, measurements, methods of percentile derivation and comprehensiveness of obesity markers investigated. This nationwide general population study developed new CS and CIMT centiles in the young and used them to study associations with body mass index, waist circumference, waist-to-height-ratio, bioimpedance-derived absolute and relative fat mass, fat-free mass, subscapular skinfold thickness and blood pressure. METHODS: In its 11-year follow-up, the KiGGS cohort, which is based on a nationally representative sample, included semi-automated state-of-the-art sonographic CIMT and CS measurements in 4,709 participants aged 14 to 28. Distensibility coefficient (DC), stiffness index ß, Young's elastic modulus (YEM) and Peterson's elastic modulus (Ep) centiles were modelled by sex, age and height simultaneously. RESULTS: CS increased with age in both sexes, and young men had stiffer arteries than young women at all ages. All obesity measures at baseline and at follow-up, except for subscapular skinfold thickness, were positively associated with several CS parameters with moderate relative risks (RR), e.g. cross-sectional RR 2.23 (95% CI 1.26-3.93) for DC ≥ 90th percentile when waist circumference ≥90th percentile; RR 5.98 (3.38-10.56) for elevated DC associated with simultaneously elevated waist circumference and BP. CONCLUSIONS: These new state-of-the-art CS percentiles show consistent associations of obesity with CS in the young and support primary prevention efforts starting at a young age.

Changes in body weight and obesity status in German adults: results of seven population-based prospective studies.

BACKGROUND/OBJECTIVES: The objective of this study was to quantify body weight changes in German adult populations during the past decades. SUBJECTS/METHODS: Longitudinal analysis of seven cohort studies covering different age ranges between 18 and 83 years. Baseline examinations were between 1994 and 2007 and follow-up durations between 4.0 and 11.9 years. For each study, mean change in body weight per year and 10-year change in body mass index (BMI) classification were analyzed. For the middle age group of 45-64 years, meta-analysis was conducted to obtain an overall estimate for Germany. RESULTS: Among men weight gain was highest in the youngest participants and decreased with advancing age. Among women weight gain was on a stable high level among those younger than 45 years and decreased at older age. Within 10 years, 30-40% of middle-aged participants with normal baseline weight became pre-obese or obese and 20-25% of those with pre-obesity at baseline became obese, whereas >80% of persons who were obese at baseline remained obese over time. The estimated average weight change in adults aged 45-64 years was 0.25 (95% confidence interval (CI): 0.18-0.33) kg/year among men and 0.24 (0.17-0.30) kg/year among women. CONCLUSIONS: We could observe a moderate weight gain over the past years in German middle-aged populations of 0.25 kg/year. Obesity prevention needs to be targeted to specific subgroups in the population, especially to younger adults, who seem to be most vulnerable for gaining weight. Obesity intervention needs to be improved, as the majority of obese adults remained obese over time.

Use of dietary supplements in the European Prospective Investigation into Cancer and Nutrition calibration study.

BACKGROUND: Dietary supplement use is increasing, but there are few comparable data on supplement intakes and how they affect the nutrition and health of European consumers. The aim of this study was to describe the use of dietary supplements in subsamples of the 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). METHODS: Specific questions on dietary supplement use were asked as a part of single 24-h recalls performed on 36,034 men and women aged 35-74 years from 1995 to 2000. RESULTS: Between countries, the mean percentage of dietary supplement use varied almost 10-fold among women and even more among men. There was a clear north-south gradient in use, with a higher consumption in northern countries. The lowest crude mean percentage of use was found in Greece (2.0% among men, 6.7% among women), and the highest was in Denmark (51.0% among men, 65.8% among women). Use was higher in women than in men. Vitamins, minerals or combinations of them were the predominant types of supplements reported, but there were striking differences between countries. CONCLUSIONS: This study indicates that there are wide variations in supplement use in Europe, which may affect individual and population nutrient intakes. The results underline the need to monitor consumption of dietary supplements in Europe, as well as to evaluate the risks and benefits.
