Abstract
Engineering non-linear hybrid light-matter states in tailored lattices is a central research strategy for the simulation of complex Hamiltonians. Excitons in atomically thin crystals are an ideal active medium for such purposes, since they couple strongly with light and bear the potential to harness giant non-linearities and interactions while presenting a simple sample-processing and room temperature operability. We demonstrate lattice polaritons, based on an open, high-quality optical cavity, with an imprinted photonic lattice strongly coupled to excitons in a WS2 monolayer. We experimentally observe the emergence of the canonical band-structure of particles in a one-dimensional lattice at room temperature, and demonstrate frequency reconfigurability over a spectral window exceeding 85 meV, as well as the systematic variation of the nearest-neighbour coupling, reflected by a tunability in the bandwidth of the p-band polaritons by 7 meV. The technology presented in this work is a critical demonstration towards reconfigurable photonic emulators operated with non-linear photonic fluids, offering a simple experimental implementation and working at ambient conditions.

Abstract
The large oscillator strength of excitons in transition metal dichalcogenide layers facilitates the formation of exciton-polariton resonances for monolayers and van-der-Waals heterostructures embedded in optical microcavities. Here, we show, that locally changing the number of layers in a WSe2/hBN/WSe2 van-der-Waals heterostructure embedded in a monolithic, high-quality-factor cavity gives rise to a local variation of the coupling strength. This effect yields a polaritonic stair case potential, which we demonstrate at room temperature. Our result paves the way towards engineering local polaritonic potentials at length scales down to atomically sharp interfaces, based on purely modifying its real part contribution via the coherent light-matter coupling strength g.

Abstract
In KiGGS Wave 2, data from 3‑ to 17-year-olds were collected from a total of 3462 persons using a standardized interview on the current use of AM/NEM in the last seven days. For trends analysis, data from 14,679 study participants in the same age group from the KiGGS baseline study were used.In KiGGS Wave 2, 36.4% (95% CI 34.1-38.8) of the 3‑ to 17-year-olds had used at least one AM/NEM in the last seven days. The prevalence was highest at 46.5% in 14- to 17-year-olds and significantly different between girls and boys (56.4% vs. 37.3%). Only among girls were there significant differences by migrant background with a higher prevalence of use among girls without a migrant background.Most frequently, the preparations used were for treatment of the respiratory tract (girls: 14.2%, boys: 14.9%), followed by "Varia" (girls: 8.7%, boys: 9.3%) and preparations for the treatment of the musculoskeletal system (girls: 8.9%, boys: 5.8%). There was a significant decrease in the overall prevalence of medicine use compared to the KiGGS baseline study (46.4% vs. 36.4%). This decrease was mainly due to lower prevalences of use in the ATC main groups "N Nervous System" (7.5% vs. 5.4%), "J Systemic Anti-infectives" (2.5% vs. 1.4%) and "H Systemic Hormones, excl. Sexual Hormones and Insulins" (2.0% vs. 1.1%).The results describe key points in the use of AM/NEM, including self-medication for children and adolescents in Germany. They illustrate the use behaviour and represent a valuable supplement to prescription data.

Abstract
BACKGROUND The benefit of medicines in the secondary prevention of coronary heart disease (CHD) has been demonstrated in women and men. However, gender-specific differences have been observed in the prescription of these medicines. Information on trends in prevalence use in women and men from population-based studies are still lacking. METHODS Data of people aged 40-79 years with CHD from the national health interview and examination surveys for adults in Germany from 1997-1999 (GNHIES98, n = 411) and from 2008-2011 (DEGS1, n = 440) were analyzed. Trend analyses via multivariable regression models, taking into account relevant covariables, were used to calculate the prevalence of medicine use in secondary prevention of CHD between GNHIES98 and DEGS1. The following groups were considered: antiplatelet, statins, beta-receptor blockers, agents acting on the renin-angiotensin system (RAS blocker), calcium-channel blockers, and nitrate. RESULTS In one decade, the prevalence had increased for antiplatelet (24.0% vs. 59.6%), statins (18.5% vs. 56.2%), beta-receptor blockers (24.7% vs. 65.5%), and RAS blockers (31.6% vs. 69.0%). The prevalence of calcium-channel blockers (33.3% vs. 20.5%) and nitrate (40.6% vs. 10.1%) had decreased. In GNHIES98, men were more likely to use RAS blockers. Significant gender differences were found in DEGS1 only for angiotensin-converting-enzyme (ACE) inhibitors. CONCLUSION This study showed an improvement in the use of drugs for the secondary prevention of CHD in both sexes.

Associations between the use of specific psychotropic drugs and all-cause mortality among older adults in Germany: Results of the mortality follow-up of the German National Health Interview and Examination Survey 1998. PLoS One 2019; 14:e0210695. [PMID: 30640945 PMCID: PMC6331145 DOI: 10.1371/journal.pone.0210695] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2018] [Accepted: 01/01/2019] [Indexed: 11/18/2022] Open
Abstract
Background Use of psychotropic drugs is common among older adults. Population-based studies on the associations of psychotropic drug use with mortality are sparse. Objectives To investigate the associations between the use of specific psychotropic drug groups (opioids, antipsychotics, antidepressants and benzodiazepines) and all-cause mortality among community-dwelling older adults in Germany. Methods Participants of the German National Health Interview and Examination Survey 1998 were followed up for mortality from 1997 to 2011. Persons aged 60–79 years with complete data on psychotropic drug use at baseline and on mortality follow-up were considered as study population (N = 1,563). Associations between the use of opioids, antipsychotics, antidepressants and benzodiazepines and all-cause mortality were examined by Cox proportional hazards models adjusted for sociodemographics (sex, age, community size, region, socioeconomic status), life style (smoking, sports, risky alcohol drinking) and health conditions (obesity, disability, history of cardiovascular diseases, diabetes, hyperlipidemia, hypertension, any cancers, any mental disorders) at baseline. Results After a median follow-up of 11.4 years, 21, 18, 23 and 26 deaths were documented among those who used at baseline opioids (n = 39), antipsychotics (n = 30), antidepressants (n = 53) and benzodiazepines (n = 54) with an unadjusted mortality rate (MR) of 57.7, 59.1, 44.6 and 53.7 per 1000 person-years, respectively. Meanwhile, 400 deaths were documented among 1,406 nonusers of any of the above mentioned psychotropic drugs with a MR of 26.7 per 1000 person-years. The age and sex adjusted mortality rate ratios in comparison with nonusers were 2.20 (95% confidence intervals 1.42–3.41), 1.66(1.03–2.70), 1.56(1.06–2.28), and 1.57(1.07–2.31) for the use of opioids, antipsychotics, antidepressants and benzodiazepines, respectively. In the fully adjusted Cox models, use of opioids (hazardous ratio 2.04, 95% confidence intervals 1.07–3.89), antipsychotics (2.15, 1.11–4.15) and benzodiazepines (1.76, 1.09–2.82), but not antidepressants, were significantly associated with an increased risk of mortality. Conclusions Use of opioids, antipsychotics, benzodiazepines is significantly associated with an increased risk of all-cause mortality among community-dwelling older adults in Germany. Clinicians should be careful in prescribing these psychotropic drugs to older adults while patients already under psychotropic therapy should well balance the risks and benefits of drug use. Further studies with a larger sample size and information on specific indications for psychotropic drug use and mental comorbidities are required to confirm the findings of the present study.

Oral health behaviour of children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends. JOURNAL OF HEALTH MONITORING 2018; 3:3-19. [PMID: 35586143 PMCID: PMC8852791 DOI: 10.17886/rki-gbe-2018-096] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/13/2018] [Accepted: 11/08/2018] [Indexed: 11/16/2022]
Abstract
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.

Abstract
In order to assess the effects of prescription-only (Rx) to over-the-counter (OTC) drug switches and related policies, it is imperative to distinguish self-medication from OTC drug use. The objective of this study was to estimate the OTC drug use in the adult population in Germany, to identify its predictors and to highlight methodological differences when compared to the study of a self-medication prevalence. Seven-day prevalence of OTC drug use was calculated on the basis of information provided by 7091 participants of the German Health Interview and Examination Survey for Adults (DEGS1) conducted between 2008 to 2011. Logistic regression analysis was used to identify predictors of OTC drug use. Seven-day prevalence of OTC drug use was higher in women (47.16%) than in men (33.17%). Female gender, an age of more than 60 years, reduced health status, Rx drug use, and multi-morbidity were identified as predictors of OTC drug use. The levels of OTC drug use were higher than the self-medication prevalence found in the same data set probably because some OTC drugs are commonly prescribed by physicians. Drug utilization studies should, therefore, make a methodological distinction between self-medication and OTC drug use depending on whether the focus is on drug safety or the impact of regulatory decisions on the trade status.

Abstract
The use of medicines is an essential aspect of treating disease. In this field, surveys that map the population's use of medicines are of particular interest. The GEDA 2014/2015-EHIS study collected data on the use of medically prescribed and self-medicated drugs during the two weeks that preceded the survey. 58.9% of women and 52.0% of men reported that they had taken medically prescribed drugs during this period. 48.5% of women and 35.4% of men stated they had taken medication during this period that had not been prescribed by a doctor. The prevalence of the use of medically prescribed drugs and self-medication was higher among women than among men. Finally, the prevalence of the use of medically prescribed drugs increased significantly with age, whereas the prevalence of self-medication decreased with age.

Abstract
Purpose To investigate the association of psychotropic drug use with falls among older adults in Germany based on data from the National Health Interview and Examination Survey for Adults 2008–2011 (DEGS1). Methods DEGS1 collected data on drug use in the past 7 days and on falls occurred in the last 12 months. Study participants were older adults aged 65–79 years with complete data on drug use and falls (N = 1,833). Odds ratio (OR) and 95% confidence intervals (95% CI) were derived from logistic regression models adjusting for potential confounders including socio-demographic characteristics, health-related behaviors (alcohol drinking), body mass index and health conditions (frailty, vision impairment, disability, polypharmacy, blood pressure) as well as use of potential falls-risk-increasing drugs. SPSS complex sample methods were used for statistical analysis. Results Compared to people without falls, people with falls (n = 370) had a higher psychotropic drug use (33.1% vs. 20.7%, p < .001). After adjusting for potential confounders, use of psychotropic drugs overall was associated with a higher risk of falls (OR 1.64, 95% CI 1.14–2.37). This was particularly true for the use of synthetic psychotropic drugs (1.57, 1.08–2.28), antidepressants overall (2.88, 1.63–5.09) or synthetic antidepressants (2.66, 1.50–4.73), specifically, selective serotonin reuptake inhibitors (SSRIs) (6.22, 2.28–17.0). Similar results were found for recurrent falls. Conclusions Use of psychotropic drugs overall, especially synthetic antidepressants like SSRIs, is associated with higher risks of falls and recurrent falls among community dwelling older adults aged 65–79 years in Germany.

Changes in prevalence of psychotropic drug use and alcohol consumption among the elderly in Germany: results of two National Health Interview and Examination Surveys 1997-99 and 2008-11. BMC Psychiatry 2017; 17:90. [PMID: 28279159 PMCID: PMC5345233 DOI: 10.1186/s12888-017-1254-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2016] [Accepted: 03/04/2017] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Psychotropic drug use and alcohol consumption among older adults need to be monitored over time as their use or combined use bears risks of harms. Representative data on changes in prevalence, patterns and co-relates of substance use are lacking in Germany. METHODS Participants were older adults (60-79 years) from two German National Health Surveys: 1997-99 (GNHIES98, N = 1,606) and 2008-11 (DEGS1, N = 2,501). Included were drugs acting on the nervous system used during the last 7 days. Alcohol consumption was measured by frequency (daily drinking) and quantity (risky drinking: ≥20/10 g/day alcohol for men/women). Changes in prevalence adjusted for potential socio-economic and health-related confounders were calculated by logistic regression models approximated by the SAS LSMEANS statement. RESULTS The prevalence of overall psychotropic drug use (20.5% vs. 21.4%) remained constant between the two surveys. Significant changes were observed in the use of some psychotropics (all GNHIES98 vs. DEGS1): Synthetic antidepressants (3.9% vs. 6.9%), St. John's wort (2.9% vs. 1.1%), benzodiazepines (3.7% vs. 2.5%), benzodiazepine related drugs (0.2% vs. 0.8%), narcotic analgesics (3.0% vs. 4.1%), anti-dementia drugs (2.2% vs. 4.2%) and anti-epileptics (1.0% vs. 2.3%). Significant changes were also observed in long-term use of synthetic anti-depressants (3.2% vs. 5.9%), St. John's wort (2.0% vs. 0.6%) and opioid analgesics (1.0% vs. 2.2%). Further, we found significant changes in benzodiazepines use (3.3% vs. 1.4%) among men, opioids use (2.9% vs. 7.3%) among people with a lower social status, and overall psychotropics (26.8% vs. 32.5%) as well as opioids use (4.4% vs. 8.1%) among those with a worse health status. Moderate alcohol consumption increased significantly (58.0% vs. 66.9%). Risky drinking remained unchanged (16.6% vs. 17.0%). In spite of significant increases in daily alcohol drinking (13.2% vs. 18.4%) psychotropic drug use combined with daily drinking remained unchanged (1.8% vs. 2.7%). CONCLUSIONS Although prevalence of overall psychotropic drug use remained stable, changes in the use of some psychotropic drug groups and alcohol consumption patterns have been observed. Further studies are required to investigate resulting health consequences and public health relevance of those outcomes.

Abstract
Background This study examines changes in physical functioning among adults aged 50-79 years in Germany based on data from two German National Health Interview and Examination Surveys conducted in 1997–1999 (GNHIES98) and 2008–2011 (DEGS1). Methods Using cross-sectional data from the two surveys (GNHIES98, n = 2884 and DEGS1, n = 3732), we examined changes in self-reported physical functioning scores (Short Form-36 physical functioning subscale (SF-36 PF)) by sex and age groups (50–64 and 65–79 years). Covariables included educational level, living alone, nine chronic diseases, polypharmacy (≥5 prescribed medicines), body mass index, sports activity, smoking and alcohol consumption. Multimorbidity was defined as ≥2 chronic diseases. Multivariable models were fitted to examine consistency of changes in physical functioning among certain subgroups and to assess changes in mean SF-36 PF scores, adjusting for changes in covariables between surveys. Results Mean physical functioning increased among adults aged 50–79 years between surveys in unadjusted analyses, but this change was not as marked among men aged 65–79 years who experienced rising obesity (20.6 to 31.5%, p = 0.004) and diabetes (13.0 to 20.0%, p = 0.014). Prevalence of multimorbidity and polypharmacy use increased among men and women aged 65–79 years. In sex and age specific multivariable analyses, changes in physical functioning over time were consistent across subgroups. Gains in physical functioning were explained by improved education, lower body mass index and improved health-related behaviours (smoking, alcohol consumption, sports activity) in women, but less so among men. Conclusions Physical functioning improved in Germany among adults aged 50–79 years. Improvements in the population 65–79 years were less evident among men than women, despite increases in multimorbidity prevalence among both sexes. Changes in health behaviours over time differed between sexes and help explain variations in physical functioning. Targeted health behaviour interventions are indicated from this study.

Time Trends in Cardiometabolic Risk Factors in Adults. DEUTSCHES ARZTEBLATT INTERNATIONAL 2016; 113:712-719. [PMID: 27866566 PMCID: PMC5143790 DOI: 10.3238/arztebl.2016.0712] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/15/2016] [Revised: 04/15/2016] [Accepted: 07/07/2016] [Indexed: 12/13/2022]
Abstract
BACKGROUND Data from three representative health examination surveys in Germany were analyzed to examine secular trends in the prevalence and magnitude of cardiometabolic risk factors. METHODS The target variables were the following cardiometabolic risk factors: lack of exercise, smoking, obesity, systolic blood pressure, total cholesterol, serum glucose, self-reported high blood pressure, hyperlipidemia, and diabetes, and the use of antihypertensive, cholesterol-lowering, and antidiabetic drugs. 9347 data sets from men and 10 068 from women were analyzed. The calculated means and prevalences were standardized to the age structure of the German population as of 31 December 2010 and compared across the three time periods of the surveys: 1990-1992, 1997-1999, and 2008-11. RESULTS Over the entire period of observation (1990-2011), the mean systolic blood pressure fell from 137 to 128 mmHg in men and from 132 to 120 mmHg in women; the mean serum glucose concentration fell from 5.6 to 5.3 mmol/L in men and from 5.4 to 5.0 mmol/l in women; and the mean total cholesterol level fell from 6.2 to 5.3 mmol/L in both sexes. In men, smoking and lack of exercise became less common. On the other hand, the prevalence of use of antidiabetic, cholesterol-lowering, and antihypertensive drugs rose over the same time period, as did that of self-reported diabetes. The first of the three surveys (1990-1992) revealed differences between persons residing in the former East and West Germany in most of the health variables studied; these differences became less marked over time, up to the last survey in 2008-2011. CONCLUSION The cardiometabolic risk profile of the German adult population as a whole improved over a period of 20 years. Further in-depth analyses are now planned.

Abstract
OBJECTIVES The use and combined use of psychotropic drugs and alcohol among older adults is a growing public health concern and should be constantly monitored. Relevant studies are scarce in Germany. Using data of the most recent national health survey, we analyse prevalence and correlates of psychotropic drug and alcohol use among this population. METHODS Study participants were people aged 60-79 years (N=2508) of the German Health Interview and Examination Survey for Adults 2008-2011. Medicines used during the last 7 days were documented. Psychotropic drugs were defined as medicines acting on the nervous system (ATC code N00) excluding anaesthetics (N01), analgesics/antipyretics (N02B), but including opiate codeines used as antitussives (R05D). Alcohol consumption in the preceding 12 months was measured by frequency (drinking any alcohol-containing beverages at least once a week/a day) and quantity (alcohol consumed in grams/day; cut-offs: 10/20 g/day for women/men defining moderate and risky drinking). SPSS complex sample module was used for analysis. RESULTS 21.4% of study participants use psychotropic medications, 66.9% consume alcohol moderately and 17.0% riskily, 51.0% drink alcohol at least once a week and 18.4% daily, 2.8% use psychotropic drugs combined with daily alcohol drinking. Among psychotropic drug users, 62.7% consume alcohol moderately, 14.2% riskily. The most frequently used psychotropic medications are antidepressants (7.9%) and antidementia (4.2%). Factors associated with a higher rate of psychotropic drug use are female sex, worse health status, certified disability and polypharmacy. Risky alcohol consumption is positively associated with male sex, smoking, upper social class, better health status, having no disability and not living alone. CONCLUSIONS Despite the high risk of synergetic effects of psychotropic drugs and alcohol, a substantial part of older psychotropic drug users consume alcohol riskily and daily. Health professionals should talk about the additional health risks of alcohol consumption when prescribing psychotropic drugs to older adults.

Reduced pain perception in children and adolescents with ADHD is normalized by methylphenidate. Child Adolesc Psychiatry Ment Health 2016; 10:24. [PMID: 27453723 PMCID: PMC4957360 DOI: 10.1186/s13034-016-0112-9] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2016] [Accepted: 06/29/2016] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND The present study examined pain perception in children and adolescents with ADHD and the interaction between pain perception and the administration of methylphenidate (MPH) in order to generate hypotheses for further research that will help to clarify the association between ADHD diagnosis, MPH treatment and pain perception. METHODS We included 260 children and adolescents of the "German Health Interview and Examination Survey for Children and Adolescents" (KiGGS) and analyzed parent's assessments of children's pain distribution and pain perception, as well as the influence of MPH administration on pain perception in affected children and adolescents. RESULTS Pain perception was associated with ADHD and MPH administration, indicating that children and adolescents suffering from ADHD without MPH treatment were reported to have lower pain perception compared to both, healthy controls (HC) and ADHD patients medicated with MPH. CONCLUSION We suggest that reduced pain perception in children and adolescents with ADHD not medicated with MPH may lead to higher risk tolerance by misjudgments of dangerous situations, expanding the importance of MPH administration in affected children and adolescents.

Abstract
OBJECTIVE This study aims to ascertain once and for all whether children and adolescents affected by ADHD show a higher risk for accidents, as well as investigating a possible association between the administration of ADHD-specific medication and the occurrence of accidents. METHOD Two exceptionally large sets of data were implemented in this analysis. Participants included children and adolescents representative of the entire German population. Data for Survey 1 was collected through extensive administration of questionnaires. Data for Survey 2 stemmed from the records of a leading German health insurance company. In terms of statistical analysis, chi-square tests as well as logistic regression analyses were applied and odds ratios (ORs) were determined. RESULTS Innovative results are presented showing a significantly higher likelihood for ADHD-affected youngsters to be involved in accidents compared with their nonaffected counterparts (Survey 1: OR = 1.60; Survey 2: OR = 1.89) but lacking an overall significant influence of medication regarding the occurrence of accidents (Survey 1: OR = 1.28; Survey 2: OR = 0.97). Frequency of accidents could be predicted by ADHD, gender, and age in both samples. Medication intake served as a weak predictor only in Survey 2. CONCLUSION It has been determined in two representative and independent German samples that youngsters with ADHD are at a significantly higher risk of being involved in accidents. In the future, this should always be considered when setting up a treatment plan to ensure a safer and healthier coming of age without relying solely on specific effects of medication. (J. of Att. Dis. 2016; 20(6) 501-509).

Changes in mean serum lipids among adults in Germany: results from National Health Surveys 1997-99 and 2008-11. BMC Public Health 2016; 16:240. [PMID: 26956524 PMCID: PMC4784325 DOI: 10.1186/s12889-016-2826-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2015] [Accepted: 02/04/2016] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Monitoring of serum lipid concentrations at the population level is an important public health tool to describe progress in cardiovascular disease risk control and prevention. Using data from two nationally representative health surveys of adults 18-79 years, this study identified changes in mean serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG) in relation to changes in potential determinants of serum lipids between 1997-99 and 2008-11 in Germany. METHODS Sex-specific multivariable linear regression analyses were performed with serum lipids as dependent variables and survey wave as independent variable and adjusted for the following covariables: age, fasting duration, educational status, lifestyle, and use of medication. RESULTS Mean TC declined between the two survey periods by 13 % (5.97 mmol/l vs. 5.19 mmol/l) among men and by 12 % (6.03 mmol/l vs. 5.30 mmol/l) among women. Geometric mean TG decreased by 14 % (1.66 mmol/l vs. 1.42 mmol/l) among men and by 8 % (1.20 mmol/l vs. 1.10 mmol/l) among women. Mean HDL-C remained unchanged among men (1.29 mmol/l vs. 1.27 mmol/l), but decreased by 5 % among women (1.66 mmol/l vs. 1.58 mmol/l). Sports activity and coffee consumption increased, while smoking and high alcohol consumption decreased only in men. Processed food consumption increased and wholegrain bread consumption decreased in both sexes, and obesity increased among men. The use of lipid-lowering medication, in particular statins nearly doubled over time in both sexes. Among women, hormonal contraceptive use increased and postmenopausal hormone therapy halved over time. The changes in lipid levels between surveys remained significant after adjusting for covariables. CONCLUSION Serum TC and TG considerably declined over one decade in Germany, which can be partly explained by increased use of lipid-lowering medication and improved lifestyle among men. The decline in serum lipids among women, however, remains unexplained.

Abstract
BACKGROUND Hypertension is a major risk factor for morbidity and mortality, therefore its control is of great importance. In this study we compare the use of antihypertensive medication among adults with hypertension in Germany 1998 and 2008-2011 and determine factors associated with use and control. METHODS Data from German Health Examination Surveys (GNHIES98 1998, n = 7,124 and DEGS1 2008-2011 n = 7,988, age 18-79 years) including standardized blood pressure (BP) measurements and Anatomical Therapeutic Chemical (ATC) medication codes were analyzed. RESULTS The use of antihypertensive medication among adults with hypertension in Germany increased from 54% to 72% in 1 decade. In 2008-2011, 67% of users were treated with polytherapy. The most commonly used antihypertensive class in 1998 was diuretics (43%) and in 2008-2011 beta-blockers (54%). Ramipril and metoprolol are currently the most commonly used monotherapy agents, while ramipril in combination with hydrochlorothiazide is the most frequent polytherapy. Being a woman, older age, having statutory health insurance, diabetes, coronary heart disease (CHD), stroke, and obesity were positively associated with antihypertensive use. The control rate among treated increased from 42% to 72%. Young women (18-54 years) had better control compared to older women or to men. Having CHD or stroke was positively associated with BP control. CONCLUSIONS Increased and improved antihypertensive use might be a main contributor to the decrease in BP observed in Germany in the last decade. However, there are still socio-demographic and health disparities in hypertension treatment and control.

Abstract
OBJECTIVES In Germany, population-wide data on adherence to national asthma management guidelines are lacking, and performance measures (PM) for quality assurance in asthma care are systematically monitored for patients with German national asthma disease management program (DMP) enrollment only. We used national health survey data to assess variation in asthma care PM with respect to patient characteristics and care context, including DMP enrollment. METHODS Among adults 18-79 years with self-reported physician-diagnosed asthma in the past 12 months identified from a recent German National Health Interview Survey (GEDA 2010: N = 1096) and the German National Health interview and Examination Survey 2008-2011 (DEGS1: N = 333), variation in asthma care PM was analyzed using logistic regression analysis. RESULTS Overall, 38.4% (95% confidence interval: 32.5-44.6%) of adults with asthma were on current inhaled corticosteroid therapy. Regarding non-drug asthma management, low coverage was observed for inhaler technique monitoring (35.2%; 31.2-39.3%) and for provision of an asthma management plan (27.3%; 24.2-30.7%), particularly among those with low education. Specific PM were more complete among persons with than without asthma DMP enrollment (adjusted odds ratios ranging up to 10.19; 5.23-19.86), even if asthma patients were regularly followed in a different care context. CONCLUSIONS Guideline adherence appears to be suboptimal, particularly with respect to PM related to patient counseling. Barriers to the translation of recommendations into practice need to be identified and continuous monitoring of asthma care PM at the population level needs to be established.

Abstract
Background Despite the public health relevance of analgesic use, large-scale studies on this topic in Germany are lacking. This study describes the prevalence, trends, associations and patterns of use of prescription and over-the-counter (OTC) analgesics, focusing on five of the most common agents: aspirin, diclofenac, ibuprofen, naproxen and paracetamol. Methods Data from two representative population-based surveys: The German National Health Interview and Examination Survey 1998 (GNHIES98 n = 7099) and the German Health Interview and Examination Survey for Adults 2008–2011 (DEGS1 n = 7091) was investigated. Information on all medicines consumed in the previous 7 days was collected via computer-assisted personal interviews with adults aged 18–79 years. Associations between analgesic use and socio-demographic and health-behaviour factors were analysed using logistic regression models. Results Analgesic use has increased over the last decade from 19 to 21 %. This was exclusively due to the rise in OTC analgesic use from 10.0 to 12.2 %. Prescribed analgesic use remained constant (7.9 %). Findings from DEGS1 indicate that ibuprofen is the most commonly used analgesic followed by aspirin and paracetamol. OTC analgesic use is higher among women and smokers, but lower among older adults (65–79 years). Prescribed analgesics use is higher among women, older adults, smokers and obese adults with medium or high socio- economic status. Adults performing more than 2 h/week of physical exercise use fewer analgesics. Discussion Among the adult population of Germany, the prevalence of OTC analgesic use has significantly increased over the last decade. We found differences between adults consuming OTC and prescribed analgesics (or both) concerning their health behaviour and health conditions. International direct comparison between prevalence rates of analgesic use was limited due to varying availability of analgesics between countries and to methodological differences. Conclusions About one in five community dwelling adults aged 18–79 years in Germany use analgesics in a given week. Considering the potential harms of analgesic use, monitoring of prevalence, patterns and determinants of use at the population level are important steps to inform disease prevention and health promotion policies.

Abstract
Background Medicines to treat common colds (CC) and upper respiratory tract infections (URTI) are widely used among children, but there are only few data about treatments actually applied for these diseases. In the present study we analyze the prevalence and correlations of self-medicated and prescribed drug use for the treatment of CCs and URTIs among children and adolescents in Germany. Methods Medicine use during the week preceding the interview was recorded among 17,450 children (0–17 years) who participated in the drug interview of the 2003–2006 German Health Interview and Examination Survey for Children and Adolescents (KiGGS). The definition of CCs and URTIs in the present study included the WHO-ICD-10 codes J00, J01.0, J01.9, J02.0, J02.9, J03.0, J03.9, J04.0, J06.8, J06.9, J11.1, J11.8, R05 and R07.0. Using the complex sample method, the prevalence and associated socio-demographic factors of self-medication, prescribed medicines and antibiotics were defined. Results 13.8% of the participating girls and boys use drugs to treat a CC or an URTI. About 50% of this group use prescribed medications. Among the users of prescribed medication, 11.5% use antibiotics for the treatment of these diseases. Looking at all prescribed medicines we find associations with younger age, immigration background, and lower social status. Antibiotic use in particular is associated with female sex, higher age, residency in the former East Germany and immigration background. Conclusions The use of medicines to treat CCs or URTIs is widespread among children and adolescents in Germany. Thus, longitudinal studies should investigate the risks associated with this drug use. Differences in socio-demographic variables regarding exposure to antibiotic use indicate that there could be an implausible prescribing behavior among physicians in Germany.

Abstract
Background Germany is a country with a high use of herbal medicinal products. Population-based data on the use of herbal medicinal products among children are lacking. The aim of this study is to investigate the prevalence, patterns and determinants of herbal medicine use among children and adolescents in Germany. Methods As data base served the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), a representative population based survey conducted 2003–2006 by the Robert Koch Institute. 17,450 boys and girls aged 0–17 years provided information on drug use in the preceding seven days. Herbal medicinal products were defined according to the European and German drug laws. SPSS Complex Sample method was used to estimate prevalence rates and factors associated with herbal medicine use. Results The prevalence rate of herbal medicinal product use amounts to 5.8% (95% confidence interval 5.3-6.3%). Use of herbal medicine declines along with increasing age and shows no difference between boys and girls in younger age groups. Teenage girls are more likely to use herbal medicines than teenage boys. Two thirds of herbal medicines are used for the treatment of coughs and colds; nearly half of herbal medicines are prescribed by medical doctors. Determinants of herbal medicinal product use are younger age, residing in South Germany, having a poor health status, having no immigration background and coming from a higher social class family. Children’s and parents-related health behavior is not found to be associated with herbal medicine use after adjusting for social class. Conclusions Use of herbal medicinal products among children and adolescents between the ages of 0 and 17 years in Germany is widely spread and shows relatively higher rates compared to international data. This study provides a reference on the use of herbal medicinal products for policy-makers, health professionals and parents. Further studies are needed to investigate the effectiveness and safety of specific herbal medicinal products, potential effects of long term use as well as possible interactions of herbal medicinal products with concomitantly used conventional medicines.

Abstract
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.

Abstract
BACKGROUND The German Health Interview and Examination Survey for Adults (DEGS) is part of the recently established national health monitoring conducted by the Robert Koch Institute. DEGS combines a nationally representative periodic health survey and a longitudinal study based on follow-up of survey participants. Funding is provided by the German Ministry of Health and supplemented for specific research topics from other sources. METHODS/DESIGN The first DEGS wave of data collection (DEGS1) extended from November 2008 to December 2011. Overall, 8152 men and women participated. Of these, 3959 persons already participated in the German National Health Interview and Examination Survey 1998 (GNHIES98) at which time they were 18-79 years of age. Another 4193 persons 18-79 years of age were recruited for DEGS1 in 2008-2011 based on two-stage stratified random sampling from local population registries. Health data and context variables were collected using standardized computer assisted personal interviews, self-administered questionnaires, and standardized measurements and tests. In order to keep survey results representative for the population aged 18-79 years, results will be weighted by survey-specific weighting factors considering sampling and drop-out probabilities as well as deviations between the design-weighted net sample and German population statistics 2010. DISCUSSION DEGS aims to establish a nationally representative data base on health of adults in Germany. This health data platform will be used for continuous health reporting and health care research. The results will help to support health policy planning and evaluation. Repeated cross-sectional surveys will permit analyses of time trends in morbidity, functional capacity levels, disability, and health risks and resources. Follow-up of study participants will provide the opportunity to study trajectories of health and disability. A special focus lies on chronic diseases including asthma, allergies, cardiovascular conditions, diabetes mellitus, and musculoskeletal diseases. Other core topics include vaccine-preventable diseases and immunization status, nutritional deficiencies, health in older age, and the association between health-related behavior and mental health.

Abstract
OBJECTIVE To investigate the prevalence, determinants and spectrum of attention-deficit hyperactivity disorder (ADHD) medication and its associations with socioeconomic status (SES), health-related behaviour and living conditions. DESIGN Observational cross-sectional study. SETTING Germany. PARTICIPANTS Representative population-based sample of non-institutionalised youth aged between 0 and 17 years (n=17 450) and examined between 2003 and 2006. MAIN OUTCOME MEASURE Prevalence and spectrum of ADHD medication (Anatomical Therapeutic Chemical (ATC) code N04BA) measured by standardised computer-assisted personal interview (CAPI) on drug use. RESULTS The overall prevalence of ADHD medication (stimulants including atomoxetine) was 0.9% (95% CI 0.7% to 1.1%). Boys used these drugs (1.5%, 1.2% to 1.8%) five times more than girls 0.3% (0.2% to 0.5%). The highest prevalence rates were for boys aged 6-10 years (2.3%, 1.7% to 3.1%S) and 11-13 (2.7%, 2.0% to 3.7%). Boys from families with no immigration background used ADHD medication almost 6 times as frequently as boys with an immigration background (1.7% vs 0.3%). Multivariate analysis (binary logistic regression) showed boys (OR 5.16, 95% CI 3.15 to 8.47), 11-year-olds to 13-year-olds (2.24, 1.28 to 3.49), children in large cities (2.18, 1.13 to 4.22), children with no immigration background (3.06, 1.34 to 6.99), and children with only a good (vs excellent) parent-rated health status (1.91, 1.18 to 3.08) being more likely to be using ADHD medication. A visit to the doctor in the last month or last quarter was associated with a higher probability for ADHD medication (3.18, 1.29 to 7.95 and 3.59, 1.45 to 8.90, respectively). CONCLUSIONS Results show prevalence rates of ADHD medication use for the German child and adolescent population that are considerably lower than published prevalence rates from the USA, but comparable with those of western European and Scandinavian countries. Lower use rates in rural versus urban regions may point to differential healthcare access. The inverse association of ADHD medication use with immigration status suggests potentially restricted access to healthcare services for immigrants or may reflect culture-specific differences in attitudes towards symptoms of ADHD.

Juvenile obesity and its association with utilisation and costs of pharmaceuticals--results from the KiGGS study. BMC Health Serv Res 2011; 11:340. [PMID: 22176689 PMCID: PMC3266211 DOI: 10.1186/1472-6963-11-340] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2011] [Accepted: 12/16/2011] [Indexed: 11/10/2022] Open
Abstract
Background According to a national reference, 15% of German children and adolescents are overweight (including obese) and 6.3% are obese. An earlier study analysed the impact of childhood overweight and obesity on different components of direct medical costs (physician, hospital and therapists). To complement the existing literature for Germany, this study aims to explore the association of body mass index (BMI) with utilisation of pharmaceuticals and related costs in German children and adolescents. Methods Based on data from 14, 836 respondents aged 3-17 years in the German Interview and Examination Survey for Children and Adolescents (KiGGS), drug intake and associated costs were estimated using a bottom-up approach. To investigate the association of BMI with utilisation and costs, univariate analyses and multivariate generalised mixed models were conducted. Results There was no significant difference between BMI groups regarding the probability of drug utilisation. However, the number of pharmaceuticals used was significantly higher (14%) for obese children than for normal weight children. Furthermore, there was a trend for more physician-prescribed medication in obese children and adolescents. Among children with pharmaceutical intake, estimated costs were 24% higher for obese children compared with the normal weight group. Conclusions This is the first study to estimate excess drug costs for obesity based on a representative cross-sectional sample of the child and adolescent population in Germany. The results suggest that obese children should be classified as a priority group for prevention. This study complements the existing literature and provides important information concerning the relevance of childhood obesity as a health problem.

Abstract
In the case presented an intravenous line for large volume infusion rates was to be placed in a patient with an aortic aneurysm during clinical preoperative care. After a high-flow catheter had been placed without any problems retraction of the guide wire was found to be impossible. Computer tomography revealed that the reason was a kink in the catheter resulting in the guide wire being nipped off. Fortunately both catheter and guide wire could be removed completely without any further complications.

Operationalizing multimorbidity and autonomy for health services research in aging populations--the OMAHA study. BMC Health Serv Res 2011; 11:47. [PMID: 21352521 PMCID: PMC3055812 DOI: 10.1186/1472-6963-11-47] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2010] [Accepted: 02/25/2011] [Indexed: 12/21/2022] Open
Abstract
Background As part of a Berlin-based research consortium on health in old age, the OMAHA (Operationalizing Multimorbidity and Autonomy for Health Services Research in Aging Populations) study aims to develop a conceptual framework and a set of standardized instruments and indicators for continuous monitoring of multimorbidity and associated health care needs in the population 65 years and older. Methods/Design OMAHA is a longitudinal epidemiological study including a comprehensive assessment at baseline and at 12-month follow-up as well as brief intermediate telephone interviews at 6 and 18 months. In order to evaluate different sampling procedures and modes of data collection, the study is conducted in two different population-based samples of men and women aged 65 years and older. A geographically defined sample was recruited from an age and sex stratified random sample from the register of residents in Berlin-Mitte (Berlin OMAHA study cohort, n = 299) for assessment by face-to-face interview and examination. A larger nationwide sample (German OMAHA study cohort, n = 730) was recruited for assessment by telephone interview among participants in previous German Telephone Health Surveys. In both cohorts, we successfully applied a multi-dimensional set of instruments to assess multimorbidity, functional disability in daily life, autonomy, quality of life (QoL), health care services utilization, personal and social resources as well as socio-demographic and biographical context variables. Response rates considerably varied between the Berlin and German OMAHA study cohorts (22.8% vs. 59.7%), whereas completeness of follow-up at month 12 was comparably high in both cohorts (82.9% vs. 81.2%). Discussion The OMAHA study offers a wide spectrum of data concerning health, functioning, social involvement, psychological well-being, and cognitive capacity in community-dwelling older people in Germany. Results from the study will add to methodological and content-specific discourses on human resources for maintaining quality of life and autonomy throughout old age, even in the face of multiple health complaints.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Drug safety in paediatric medication is a public health concern. According to previous studies, the incidence of adverse drug reactions (ADRs) varies greatly from 0.7% to 2.7% among paediatric outpatients and from 2.6% to 18.1% among paediatric inpatients. Little has been reported on the risks of drug use in the general child population. WHAT THIS STUDY ADDS Our study showed that the prevalence of perceived ADRs in Germany was 0.9% among non-institutionalized children in general and 1.7% among children who had used at least one medicine within the 7 days before the medical interview. Perceived ADRs in the general child population were clustered with gastrointestinal disorders and subcutaneous tissue disorders. They appeared to be mild and at the lower limits of the range reported in other studies. Health surveys covering the use of a diverse range of drugs might be suitable for computing ADR prevalence and for identifying risk factors among non-institutionalized children. They should be taken into account together with other pharmacovigilance systems. AIMS Little has been reported on the risks of drug use in the general child population. This study investigated perceived adverse drug reactions (ADRs) among non-institutionalized children in Germany. METHODS All medicines used in the last 7 days before the medical interview were recorded among the 17 450 children aged 0-17 years who participated in the 2003-06 German Health Interview and Examination Survey for Children and Adolescents (KiGGS). Perceived ADRs were reported by the children's parents and confirmed by trained medical professionals during the medical interview. RESULTS One hundred and fifty-seven medicines were involved in the occurrence of 198 perceived ADRs in 153 patients. This corresponded to 1.1% of total used drugs, 0.9% (95% confidence intervals 0.7, 1.1%) of all children, and 1.7% (1.4, 2.1%) of children treated with medications. About 40% of all perceived ADRs involved gastrointestinal disorders and 16% involved skin tissue disorders. Perceived ADRs were most frequently reported in relation to drugs acting on the nervous system (25.8%), followed by systemic anti-infectives (18.7%) and drugs acting on the respiratory system (16.2%). Risk factors for perceived ADRs included older age groups, polypharmacy (>or=2) and a poor health status. CONCLUSION Perceived ADRs in the general child population were clustered with gastrointestinal disorders and subcutaneous tissue disorders. They appeared to be mild and at the lower limits of the range reported in other studies. Health surveys covering the use of a diverse range of drugs might be suitable for computing ADR prevalence and identifying risk factors among non-institutionalized children. They should be taken into account together with other pharmacovigilance systems.

Abstract
AIMS Despite the widespread use of self-medication among the child population and the potential harm it can do, up-to-date epidemiological data on self-medication are sparse worldwide. The aim was to investigate the prevalence and correlates of self-medication use among non-institutionalized children in Germany, focusing on the paediatric self-medications that are most frequently used. METHODS All cases of last-week medicine use were recorded among 17 450 children aged 0-17 years who participated in the 2003-2006 German Health Interview and Examination Survey for Children and Adolescents. Self-medication was defined as the use of medicines that had either been bought over the counter or obtained from other sources (OS). The complex sample method was used to estimate the prevalence of, and factors associated with self-medication use. RESULTS During the previous week 25.2% of participants had used self-medication (17.0% used over-the-counter drugs and 9.9% other-sources drugs). Self-medication accounted for 38.5% of total medicine use and included all medication classes. These clustered among drugs acting on the respiratory system (32.1%), alimentary tract and metabolism (21.6%), skin (14.2%) and nervous system (11.3%), as well as homoeopathic preparations (8.6%). Vitamin preparations were most frequently used with a weighted user prevalence of 4.7% (5.2% vs. 4.1%, P < 0.001, boys vs. girls), followed by cough and cold medicines (CCMs) 4.4% (4.3 vs. 4.5, P > 0.05) and analgesics 3.7% (3.0% vs. 4.4%, P < 0.001, both boys vs. girls). Overall use of aspirin among children <12 years old was 0.3%; use of CCMs was substantial (4.4%), particularly among children <6 years old. Use of self-medication was closely related to older adolescent ages of between 14 and 17 years (odds ratio 1.16; 95% confidence interval 1.00, 1.33), children with a poor health status (1.29; 1.10, 1.52), with no immigration background (1.55; 1.33, 1.80), from families with a higher household income (1.23; 1.06, 1.42) and with mothers with a higher educational level (1.37; 1.19, 1.57). CONCLUSIONS Self-medication use is highly prevalent in Germany, particularly among children and adolescents from families with a higher socioeconomic status. Self-medication in younger children using such drugs as CCMs and aspirin suggested inappropriate drug use and potential risks. This should be closely monitored and warrants an education programme for parents in Germany.

Abstract
BACKGROUND There are virtually no prospective cohort studies in Germany regarding the changes of menopausal hormone therapy (HT) use pattern and factors associated with HT discontinuation after the release of the Women's Health Initiative (WHI) trial results. METHODS We assessed HT prevalence and use pattern as well as factors associated with HT discontinuation in a cohort of 903 women 40 years of age and older, who participated in two consecutive follow-up visits in a 20-year prospective health study from July 2000 to February and from August 2002 to December 2004. RESULTS Overall, the prevalence of HT users in the cohort declined significantly from 35.4% in 2000-2002 to 22.5% in 2002-2004. Adjusting for aging of the population, a statistically significant decrease in HT user prevalence was consistently observed across subgroups of HT users defined by type and duration of HT use. The decline was most pronounced with respect to women using combined estrogen-progestin regimens (-10.5%), higher-dose estrogens (-11.6%), oral preparations (-11.1%), as well as long-term HT users (-8.4%). The prevalence of women indicating HT use for climacteric symptoms decreased significantly (-12.4%), whereas the prevalence of women reporting use of HT for the prevention of osteoporosis increased (+1.8%) significantly. Irrespective of hysterectomy status, half of the women who continued HT changed their HT preparations and switched to lower estrogen doses (11.5%), topical estrogens (8.2%), or phytohormones (3.8%). We did not observe any significant differences between women who continued and discontinued HT regarding health-related characteristics of the study population as of 2000-2002. However, women seeing a gynecologist in the 12 months preceding the 2002-2004 visit were significantly less likely to discontinue HT use in bivariate and multivariate analyses. CONCLUSIONS Substantial declines in HT user prevalence as well as changes in HT use patterns to lower-dose estrogen preparations and non-oral routes of administration are likely to reflect effects of the publication of the WHI results. Consulting a gynecologist appeared to be relevant for a woman's decision to continue HT.

Abstract
OBJECTIVE The aim of this study was to identify the "real-life" prevalence of psychotropic medications in children and adolescents in Germany and related behavioral and emotional problems. Data from the nationwide representative National German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were analyzed. METHOD A total of 17,450 subjects aged 0-17 years from 167 communities were examined as part of the KiGGS in Germany between 2003 and 2006 to determine their use of antidepressants, antipsychotics, anxiolytics, and sedatives within the 7 days prior to being interviewed. Medication use was assessed by a medical doctor who conducted a computer-assisted personal interview (CAPI) with the parents, and related emotional and behavioral problems were assessed using the Strength and Difficulties Questionnaire (SDQ). RESULTS The overall prevalence for these medications was moderate (4.81/1000; 95% confidence interval [CI], 3.70-6.26), but prevalence varied across the different classes of drugs (sedatives > antipsychotics > antidepressants > anxiolytics). Rates of off-label use were high for antipsychotics and antidepressants. About 30% of the medication, especially sedatives, was used without prescription. Subjects using psychotropic medication obtained higher scores in the screening for emotional or behavioral problems than the total sample, but 40% of the children did not show abnormal scores. CONCLUSION The indication for antipsychotics was mostly behavioral symptomatology, while antidepressants were used for a wide variety of symptoms. The high proportion of children and adolescents using psychotropic medication with normal scores in the emotional and behavioral screening was remarkable. It cannot be determined whether in these cases low scores were related to improvement in symptoms or whether medication was being misused.

Abstract
BACKGROUND Psoriasis is a common dermatological disorder characterized by an immune-mediated chronic inflammation which is associated with a variety of other diseases commonly referred to as comorbidities. The treatments for these diseases may interfere with the course and the treatment of psoriasis. Little is known on the general drug intake of patients with psoriasis. OBJECTIVES To gain more insight into the general drug intake of patients with severe psoriasis. A correlation of comedication to respective diseases could lead to a better knowledge of comorbidities. METHODS Data on demographics, comedication and comorbidities from 1203 patients with severe psoriasis in Germany were analysed. As a control group data from 7099 subjects from the German National Health Survey 1998 were used. RESULTS Patients with severe psoriasis are receiving significantly more different systemic drugs on average than the general population, with the most prominent difference in multidrug treatment. Drugs used in the treatment of arterial hypertension, diabetes mellitus and other diseases of the metabolic syndrome as well as oral anticoagulants and anticonvulsant agents showed the greatest differences. Special characteristics of antihypertensive drug treatments could be determined. CONCLUSIONS The data obtained in this study provide the basis for an improved management of patients with psoriasis. Knowledge of existing comedication and comorbidities may lead to the ability to treat psoriasis and comorbidities at the same time more safely and to use possible synergistic effects.

Abstract
Despite successful prevention and the possibility to directly control oral health by individual behaviour, children are still affected by caries. Aim of this article is to determine the prevalence and the social factors influencing selected aspects of oral health behaviour based on data of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). Over a period of three years, 17,641 children and adolescents aged 0 to 17 years - a representative sample for Germany - were examined in the nationwide KiGGS study. Based on a written survey and a medical interview, data on oral health behaviour were also collected. 29 % of the surveyed children and adolescents brushed their teeth only once daily or less frequently. This type of teeth brushing behaviour shows a social status gradient (low: 39 %, middle: 28 %, high: 22 %) and is more frequently found in children with a migration background (45 %) than in those without a migration background (26 %). Differences were also found between girls and boys (girls: 25 %; boys: 33 %). In only 8 % of cases, parents stated that their children have a dental check-up less than once a year. However, this information substantially differs from the actual visits to dentists. Here again, differences regarding social status (low: 12 %; high: 6 %) and migration status (migrants: 16 %; non-migrants: 6 %) were found. According to the parents, 43 % of the 0-to-2-year-olds and 7 % of the 3-to-6-year-olds use pharmaceutical preparations for caries prevention. Relevant differences were found between migrants (5 %) and non-migrants (8 %). These results show that there is primarily a need for social status-specific and culture-specific prevention. To identify starting points for effectively offering preventative measures, a systematic study into the factors causing these behavioural differences is needed.

Abstract
In the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), data on the current use of medicines during the last 7 days prior to the examination were collected from 17,450 subjects aged 0 to 17 years by means of a standardised interview conducted by a physician. 50.8 % of all children and adolescents reported to have used at least 1 medication. Prevalence was found to be highest (74.9 %) in the age group 0 to 2 years. Girls showed with 53.1% a significantly higher prevalence rate than boys (48.7 %). Children from families with low socioeconomic status and children from migrant families stated a less frequent use of medication compared to children from families with higher socio economic status and no migration background. Most frequently, the boys and girls used medicines for the treatment of respiratory tract conditions (ATC code R00: 16.8%). This was followed by Alimentary System and Metabolism (ATC code A00: 16.0%) and Dermatological Preparations (ATC code D00: 9.7%). The most frequent indications included with 12.4% of all medicines reported Other Specified Prophylactic Measures (ICD code Z29.8), with 11% Acute Rhinopharyngitis (ICD code J00), and with 10. 9 % Cough (ICD code R05). Most of the drugs named were prescribed by a doctor (58%), one quarter (25%) was independently bought without prescription, 14% came from other sources, including the medicine chest, and 2% were prescribed by a non-medical practitioner. Regarding the duration of use, short-term use (less than 1 week: 55%) was encountered most frequently, while a duration of use of at least one year was reported for 13% of all medicines named. The results presented here describe the key points of medicine use among children and adolescents in Germany and are representative for this population segment. Based on the extensive data collected, further aspects, such as co- and multi-medication, are addressed. In addition, special drug segments of public health interest shall be represented in the future.
