RESUMEN
Achieving an understanding of the extent of micronutrient adequacy across Europe is a major challenge. The main objective of the present study was to collect and evaluate the prevalence of low micronutrient intakes of different European countries by comparing recent nationally representative dietary survey data from Belgium, Denmark, France, Germany, The Netherlands, Poland, Spain and the United Kingdom. Dietary intake information was evaluated for intakes of Ca, Cu, I, Fe, Mg, K, Se, Zn and the vitamins A, B1, B2, B6, B12, C, D, E and folate. The mean and 5th percentile of the intake distributions were estimated for these countries, for a number of defined sex and age groups. The percentages of those with intakes below the lower reference nutrient intake and the estimated average requirement were calculated. Reference intakes were derived from the UK and Nordic Nutrition Recommendations. The impact of dietary supplement intake as well as inclusion of apparently low energy reporters on the estimates was evaluated. Except for vitamin D, the present study suggests that the current intakes of vitamins from foods lead to low risk of low intakes in all age and sex groups. For current minerals, the study suggests that the risk of low intakes is likely to appear more often in specific age groups. In spite of the limitations of the data, the present study provides valuable new information about micronutrient intakes across Europe and the likelihood of inadequacy country by country.

Regular physical activity can have a positive effect on health at any age. Today's lifestyles, however, can often be characterised as sedentary. Therefore, the promotion of physical activity and sports has become an integral part of public health measures. The representative data of adults aged 18 to 79 years in Germany obtained from the "German Health Interview and Examination Survey for Adults" (DEGS1) provide an overview of self-estimated current physical activity behaviour. The results show that one third of the adult population claims to pay close attention to reaching a sufficient level of physical activity and one fourth participates in sports for at least 2 h/week on a regular basis. Thus, the percentage of adults regularly engaged in sports has increased compared to the previous "German National Health Interview and Examination Survey 1998". Still, four out of five adults do not achieve at least 2.5 h/week of moderate-intensity physical activity as recommended by the World Health Organisation. Consequently, future individual-level and population-level interventions should focus on target group-specific measures while continuing to promote regular physical activity in all segments of the population.

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.

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.

The study analyses the distribution of physical and sporting activity among the adult population in Germany. The data came from the "German Health Update 2009" survey, which is based on 21,262 telephone interviews conducted by the Robert Koch Institute between July 2008 and June 2009. The study shows that 56% of men aged 18 and over and 38% of women in the same age group engaged in physical activity with an intensity that made them sweat or be out of breath for at least 2.5 h/week. In addition, 64% of both men and women stated that they had actively engaged in sporting activities over the previous 3 months. Comparing 1998 and 2003, participation in sport was observed to have increased among men and women in all age groups over time. Furthermore, socio-economic differences were observed, indicating lower physical activity among higher-status groups and lower sporting activity among lower-status groups. Measures to promote physical activity and sport prove to be especially necessary for people who are not physically active (19% of men and 26% of women) or who do not engage in sport at all (36% of both men and women).

This article provides an overview of primary prevention measures to promote physical activity. First, health-related recommendations for physical activity are presented together with a brief description of the frequency and determinants of physical activity. Prevention measures in Germany to promote physical activity are categorized taking into account the respective level of intervention (individual, setting, population) and contextual reference (with and without relying on structural conditions). Typical preventive measures to promote physical activity will be presented along with some examples. This is followed by concluding remarks about the current state in the area of preventive measures in Germany for the promotion of physical activity.

From 2003-2006, the health status of 17,641 girls and boys was comprehensively assessed by interview and medical examinations in the nationwide German Health Interview and Examination Survey for Children and Adolescents (KiGGS). Therewith, data exists for a broad spectrum of health relevant questions in childhood and adolescence, including indicators, determinants and consequences of obesity. As part of the health monitoring system of the Robert Koch Institute, KiGGS is being continued as a longitudinal study. This enables the observation of health development of children and adolescents up to adulthood as well as the detection of changes in behavior and circumstances within this population. This offers many new perspectives for analyses, whose findings may be helpful for the prevention of obesity. Current insights and future perspectives are discussed.

Monitoring and quality assurance are gaining in importance for the identification of needs and the effectiveness of prevention and health promotion activities. This paper presents examples of activities of monitoring and quality assurance at the federal level, carried out by the Federal Centre for Health Education and the Robert Koch Institute. Examples include the prevention issues "HIV/AIDS", "nutrition and physical activity" and "child health". They illustrate the roles of epidemiological surveillance, health monitoring, evaluation, and intervention reporting. The Robert Koch Institute and the Federal Centre for Health Education provide complementary information on health and intervention reporting at the federal level. With their reports, they provide essential information for health policy to formulate, to implement and to evaluate evidence-based national health goals and action plans.

The study EsKiMo (Eating study as a KiGGS Module) was conducted from January to December 2006 as a follow-up study of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). With data from this study, the alcohol consumption of adolescents in Germany is explored. Interviews were conducted with 1272 adolescents, aged 12 to 17 years, using the dietary assessment software DISHES which is based on the diet history method. From consumption data of the previous four weeks, means and percentiles of the average daily consumption of alcoholic beverages as well as pure alcohol intake were calculated, stratified by age, sex, new and old federal states, social status, type of school, and migration background. Furthermore, the associations of these variables with alcohol intake were determined in univariate and multiple linear regression analyses. The highest amount of alcoholic beverages is consumed as beer. Among 16- to 17-year-olds, boys consume on average 10.4 g alcohol and girls 3.8 g alcohol per day and even 11% of boys and 6% of girls exceed the tolerable upper intake levels for adults. Alcohol consumption increases significantly with age (p< 0.001), boys drink significantly more alcohol than girls of the same age (p< 0.001), and migrants significantly less than non-migrants (p< 0.05). Differences between new and old federal states, social status, and type of school are not statistically significant. Alcohol consumption is high among adolescents, most particular among boys aged 16 to 17 years. Since about a quarter of 12- to 13-year-olds consumed alcohol at least once in the last four weeks, there is a need for action already in this age group.

Health targets are increasingly becoming a health-policy control instrument, both nationally and internationally. In the project gesundheitsziele.de, targets have been formulated for children and adolescents in Germany - currently in the areas of nutrition, exercise, and stress management. Implementing and evaluating health targets requires regularly updated, informative data that allow a comprehensive and precise description of the relevant problems and developments. The Robert Koch Institute's National Health Interview and Examination Survey for Children and Adolescents - conducted during the period from 2003 to 2006 - provides a pool of data with information on virtually all facets of health development during childhood and adolescence which can be used to determine the starting point of the health-targeting process. This article describes the data provided by the survey of the areas nutrition, exercise, and stress management and the contribution these data could make towards further developing and implementing the health targets for children and adolescents.

This study aimed at estimating the prevalence in adults of complying with the aerobic physical activity (PA) recommendation through transportation-related walking and cycling. Furthermore, potential determinants of transportation-related PA recommendation compliance were investigated. 10,872 men and 13,144 women aged 18 years or older participated in the cross-sectional 'German Health Update 2014/15 - EHIS' in Germany. Transportation-related walking and cycling were assessed using the European Health Interview Survey-Physical Activity Questionnaire. Three outcome indicators were constructed: walking, cycling, and total active transportation (≥600 metabolic equivalent, MET-min/week). Associations were analyzed using multilevel regression analysis. Forty-two percent of men and 39% of women achieved ≥600 MET-min/week with total active transportation. The corresponding percentages for walking were 27% and 28% and for cycling 17% and 13%, respectively. Higher population density, older age, lower income, higher work-related and leisure-time PA, not being obese, and better self-perceived health were positively associated with transportation-related walking and cycling and total active transportation among both men and women. The promotion of walking and cycling among inactive people has great potential to increase PA in the general adult population and to comply with PA recommendations. Several correlates of active transportation were identified which should be considered when planning public health policies and interventions.

OBJECTIVE: To analyze vitamin D status based on serum 25-hydroxyvitamin D (25OHD) measurements, its determinants and health correlates in a representative sample of German adults. SUBJECTS: A total of 1763 men and 2267 women, 18- to 79-year old, who participated in the representative German National Health Interview and Examination Survey 1998 and the integrated German Nutrition Survey. RESULTS: The median vitamin D intake from both diet and supplements did not meet the recommended level of 5 microg/day, in either men (2.8 microg/day) or women (2.3 microg/day). Altogether 80.9% of men and 88.5% of women had vitamin D intakes below this level. Moderate (12.5-25 nmol/l serum 25OHD levels) and mild (25-50 nmol/l) vitamin D deficiency was prevalent in the adult population in Germany, even in younger age groups. Overall, 57% of men and 58% of women had vitamin D levels below 50 nmol/l. Among 65- to 79-year-old women, the proportion amounted to 75%, even during the sunnier half of the year. In sex-specific multiple linear regression models, independent determinants of serum 25OHD levels consistently included season, vitamin D intake from both diet and supplements, physical activity and living in a partnership. In addition, age and current menopausal hormone use contributed to the model among women, as opposed to time of day of blood sampling and body mass index (marginally) among men. Significantly lower serum 25OHD levels were observed in women with hypertension, cardiovascular diseases and noninsulin-treated diabetes mellitus as well as in men with insulin-treated diabetes mellitus compared with nonaffected participants. CONCLUSIONS: Vitamin D deficiency is a public health issue in Germany. We identified a number of determinants with potential for primary prevention of vitamin D deficiency. Risk and benefits of preventive actions need to be examined in further studies.

BACKGROUND: As part of the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2), food and nutrient intake of children and adolescents aged 6-17 years living in Germany is assessed in EsKiMo II - the Eating Study as a KiGGS Module. METHODS: EsKiMo II is a cross-sectional study, conducted from June 2015 until September 2017. The study population comprises 6 to 17-year-old study participants from the cross-sectional sample of KiGGS Wave 2 in 167 KiGGS sample points, which are revisited by trained nutritionists. Dietary intake is assessed by weighted food records during three consecutive days plus one randomly selected day within the following 3 months for children aged 6-11 years. Dietary intake for adolescents aged 12-17 years is assessed by computer-assisted dietary history interviews, reflecting the past four weeks, using the software DISHES. Further information, for example, about specific diets and dietary supplement intake, is reported during a standardised computer assisted interview for all participants. Food items are coded by the German Food Code and Nutrient Database (BLS 3.02). DISCUSSION: EsKiMo II provides actual data on the dietary behaviour of children and adolescents living in Germany and their determinants. Results of EsKiMo II will be relevant for decision-making, measures, and evaluations within nutrition, consumer and health policy.
RESUMEN
Dietary intake of long-chain polyunsaturated fatty acids (EPA and DHA) was analysed, stratified by sex and age groups, using data from the German Nutrition Survey 1998. The median intake of both fatty acids combined (EPA and DHA) was 141 mg per day among women and 186 mg among men. In all age groups, women consumed less EPA and DHA than men, partly because of lower total intake. The lowest median intake was observed among women aged 18-24 years (84 mg) and the highest median intake among men aged 45-54 years (217 mg). The main sources of these fatty acids are fish (68%), eggs (12%), poultry (7%), meat and sausages (7%). The remaining 6% of EPA and DHA is supplied by bakery products.

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.

OBJECTIVE: To explore differences in food and nutrient intake as well as cardiovascular risk factors between the eastern and western parts of Germany in 1998 and to compare food consumption information between 1991 and 1998. DESIGN AND SUBJECTS: In all, 4030 people, aged 18-79 y, sampled from the East and West parts of Germany participated in the German Nutrition Survey (1998) by completing dietary histories and being assessed for cardiovascular risk factors. In a separate analysis, two food frequency data sets were compared from National Health Surveys conducted in 1991 (n = 7466) and in 1998 (n = 4556). RESULTS: In 1998, East Germans consumed more bread, fruit, fish, sausage, offal, and men additionally more cakes/cookies, beer and soft drinks than West Germans. They consumed less cereals, pasta, sweets, leafy vegetables, tea and drinking water, and men less vegetables and wine and women less pastry/crackers, potatoes and animal fat compared with their counterparts in West Germany. East Germans had a higher intake of total vitamin A, retinol, vitamin D, vitamin B12 and chloride, and in addition men of alcohol, and women of monosaccharides. They had a lower intake of total water, vitamin K, calcium, magnesium and manganese, and men of linoleic acid, and women of vitamin E than their West German counterparts. In East Germany, higher mean systolic blood pressure, and total and high-density lipoprotein cholesterol concentrations were found in men, and a lower mean total serum cholesterol concentration found in women compared with West Germany. CONCLUSION: Differences in food intake between the eastern and western parts of Germany still existed in 1998, although these differences were smaller than those observed 1 y after the reunification.

OBJECTIVE: To analyse the current vitamin intake and the contribution of dietary supplements to this intake of 4030 participants of the German Nutrition Survey (GeNuS) 1998, which was part of the representative German National Health Interview and Examination Survey (GNHIES), conducted from October 1997 until March 1999. DESIGN: In the GeNuS participants were interviewed comprehensively about their usual diet and supplementation patterns using a modified dietary history. SETTING: Population-based nutritional survey. SUBJECTS: A subsample of 4030 persons, aged 18-79 y, randomly selected from the GNHIES 1998. RESULTS: The contribution of dietary supplements to the vitamin intake reached 5% for vitamin E among men and 6% for vitamin C among women. Among the group of regular users, the contribution to the vitamin E intake is 36% among men and 43% among women. A substantial part of the population does not reach the current recommendations for some vitamins, especially for folate and vitamin E through their diet alone. Among regular supplement users, about one-third for folate and about half for the other vitamins reach the recommended intake only when supplemental intake is considered. Among the regular users of folate supplements, this proportion is about half. CONCLUSION: If reference values are used as preference intake, a substantial population part improves their vitamin intake by taking supplements regularly. Nevertheless, there are persons who stay below the reference values including supplemental intake or already consume more than 100% of recommendation excluding supplemental intake.

BACKGROUND: The EFCOSUM (European Food Consumption Survey Methods) Project aims at harmonizing food consumption surveys in European countries within the perspective of an overall Public Health Monitoring Programme. Harmonization implies the need for a common framework of procedures and tools, that are applicable and feasible in all potentially interested countries. A major element in such a framework is the protocol for the operationalization of a food consumption survey, referring to all practical, logistical and material conditions that need to be fulfilled in order to guarantee a successful implementation of such a survey. OBJECTIVE: The objective of this paper was to review a number of aspects of operationalization of food consumption surveys in detail. On the basis of the currently available knowledge and experience in Europe, consensus recommendations have been elaborated for an operationalization protocol that would be feasible for all European countries. METHODS: The EFCOSUM recommendations with respect to operationalization of food consumption surveys in Europe are mainly based on three sources of information, which have been discussed at several ad hoc expert meetings: experience from previous collaborative epidemiological studies, literature searches and results of two questionnaires, distributed among representatives from 23 European countries-all experts affiliated with experienced organizations in the fields of nutrition research and related fields. RESULTS: Consensus recommendations have been set up for the following topics: sampling, recruitment, fieldwork, biomarkers, interviewer qualifications and training and quality control. These recommendations have to be considered the best achievable common denominator within Europe at this time. In a number of cases, recommendations are presented in a hierarchical way, with a gradation from first choice options towards acceptable alternatives. CONCLUSIONS: It can be concluded that a high degree of standardization of fieldwork can be achieved within Europe. A number of specific problems and constraints will have to be solved in connection with the conduction of a real survey. These problems include, amongst others, country-specific decisions on, for example, target population, detailed sampling and recruiting procedures, interview setting and support. However, on the whole, these problems can be overcome and the main recommendations presented in this paper are considered feasible for every country in Europe. Application of the EFCOSUM operationalization protocol in European countries will contribute significantly to the quality and comparability of food consumption data across Europe. It is anticipated that the policy supporting and orienting potential of this type of databases-both at the national and at the EU supranational level-will be increased accordingly.

OBJECTIVE: In nutritional research, a growing interest in the use of computer-assisted cross-check dietary history interview methods exists in order to improve cost-effectiveness. The introduction of such a method in an ongoing longitudinal study was evaluated with special emphasis on the effect on interviewer bias. DESIGN: A study for the interviewer bias within and the agreement between a previously used paper-based face-to-face cross-check dietary history interview method and a newly developed interviewer-administered computer-assisted version of this interview method. SUBJECTS: The interviewer bias of 436 face-to-face interviews is compared with that of 352 computer-assisted interviews. A subset of 82 subjects underwent a face-to-face interview at the mean age of 27 and 32 y and a computer-assisted interview at their mean age of 36 y. Energy, three macronutrients (protein, fat and carbohydrate), two micronutrients (calcium and iron) and alcohol intakes obtained by these three measurements are compared to analyse the agreement between the two interview methods. RESULTS: ANOVA showed no interviewer bias for all seven analysed nutrients within the data from the computer-assisted interview, while for the face-to-face interview method, several nutrients varied significantly among the interviewers. Five different measures, used to analyse the agreement (differences, Pearson's correlation, ICC, square weighted kappa and Bland-Altman plots), showed no relevant differences between the two cross-check dietary history interview methods. CONCLUSIONS: It is concluded that the computer-assisted interview caused a reduction of interviewer bias and is of similar quality to the face-to-face interview method. Computerization of a paper-based interview can be implemented in a running cohort if a change in method is unavoidable.

In 2006, 20 % of adolescents aged 12-17 years used dietary supplements. Persons with high physical activity levels as well as those with high education levels consumed dietary supplements more often than others. Many supplement users used only one single-nutrient supplement. A similarly large proportion of users consumed one supplement with multiple nutrients. Most often supplements containing vitamin C, magnesium, B-vitamins, vitamin E and calcium were used.
