[Motor Skills of Extremely Obese Children and Adolescents Based on the Multicentre Longitudinal Obesity Database (APV)]. / Motorische Fitness extrem adipöser Kinder und Jugendlicher basierend auf der multizentrischen Adipositas-Patienten-Verlaufsdokumentation (APV).

BACKGROUND: Obese children and adolescents often exhibit progressively declining motor skills. To support young obese patients adequately, it is necessary to assess their individual physical and motor abilities, taking the degree of obesity into account. PATIENTS: A total of 5 924 children and adolescents (mean age: 12.7±2.5 years, range 6.0-18.0 years, 3 195 girls) were examined in a standardised multicentre evaluation survey (APV). Fitness parameters were correlated with age- and gender-specific BMI-SDS (Standard Deviation Score) Methods: Anthropometric data were collected and patients performed the modified Munich fitness test (mMFT: maximal power, coordination, trunk flexibility) and a 6-min walk-test (aerobic endurance capacity). RESULTS: 33% of patients were extremely obese (BMI>99.5th percentile). Mean BMI-SDS was + 2.32±0.53 (♀-Δ=+ 0.06; p<0.001). The data indicated significant negative correlations between BMI-SDS and selected components of motor performance, especially maximal power (r=- 0,134), and particularly aerobic endurance capacity (r=- 0,214; all p<0.001). Motor performance was significantly below average (n=27 473, 6-18 years), especially among extremely obese patients. Performance in all motor tasks was lower in girls compared to boys, except for trunk flexibility (p<0.001). CONCLUSION: Correlations were found between BMI-SDS and motor performance. Extremely obese patients and obese girls showed the most pronounced motor deficits. These results emphasize the importance of standardized evaluation of individual motor performance in children and adolescents with obesity.

[Hypertension, dyslipoproteinemia and BMI-category characterise the cardiovascular risk in overweight or obese children and adolescents: data of the BZgA-observational study (EvAKu-J-project) and the KiGGS-study]. / Hypertonie, Dyslipoproteinämie und BMI-Kategorie charakterisieren das kardiovaskuläre Risiko bei übergewichtigen oder adipösen Kindern und Jugendlichen: Daten der BZgA-Beobachtungsstudie (EvAKuJ-Projekt) und der KiGGS-Studie.

BACKGROUND: The considerable increase of obesity in children and adolescents poses a major challenge to the health care system. METHODS: In an observation study of the Bundeszentrale für gesundheitliche Aufklärung (BZgA) somatic data of 1916 overweight and obese children and adolescents aged 8-17 years were compared to data of 7 451 normal weight children and adolescents (KiGGS). Age, sex, body weight, height, BMI-SDS, blood pressure, and lipids were analyzed. Body weight was assessed using the BMI categories of the Arbeitsgemeinschaft Adipositas im Kindes- und Jugendalter (AGA) guidelines. Blood pressure measurements were given as above 95 (th) percentile and categorized according to the classification of the European Society of Hypertension (ESH). In addition blood pressure in BZgA-patients were estimated as above 95 (th) percentile by age, sex and height in German normal weight children and adolescents. Lipid values were evaluated according to American Heart Association specifications. RESULTS: Out of the participants of BZgA-study 14% were overweight, 48% obese, and 38% extremely obese. Blood pressure values were above the 95 (th) percentile (ESH) in 35%. The blood pressure in normal weight participants of the KiGGS-study were elevated in 5%. Total cholesterol of BZgA-patients was elevated in 13%, LDL-cholesterol was elevated in 13%, HDL-cholesterol was low in 7%, and triglycerides in the fasting state were elevated in 12%. CONCLUSIONS: The rising prevalence of cardiovascular risk factors in children and adolescents with increasing BMI category requires effective strategies for prevention and treatment of obesity.

[Evaluation of obesity treatment in children and adolescents (EvAKuJ Study). Role of therapeutic concept, certification, and quality indicators]. / Evaluation von Therapieangeboten für adipöse Kinder und Jugendliche (EvAKuJ-Projekt). Welche Rolle spielen Behandlungskonzept, AGA-Zertifizierung und initiale Qualitätsangaben?

AIM: Different providers of obesity treatment in children and adolescents in Germany were compared using the following criteria: outpatient/inpatient; with/without AGA certification; good/less good quality. METHODS: A total of 1,916 patients (8-16.9 years) from 48 study centers were examined before (t0), after (t1), and at least 1 year after therapy (t2/3). Body mass index (BMI), blood pressure, blood lipids, and psychosocial data were measured. RESULTS: Patients from inpatient rehabilitation centers were older and more obese. Patients from AGA-certified centers were more obese, and the completeness of comorbidity screening was higher. There were no differences in short- or long-term BMI reduction. "Good" treatment centers (classified after the UKE study 2004) did not differ from those centers not rated as "good" in weight reduction. Patients treated in "good" centers were more obese, and screening for comorbidity was better. No differences in drop out and loss to follow-up were found. CONCLUSION: There were only small differences between the different groups. Pronounced differences were found between the individual treatment centers. In order to improve therapy processes and outcomes, benchmarking and quality management have to be extended.

[Overweight and obesity in childhood and adolescence. Evaluation of inpatient and outpatient care in Germany: the EvAKuJ study]. / Übergewicht und Adipositas in Kindheit und Jugend. Evaluation der ambulanten und stationären Versorgung in Deutschland in der "EvAKuJ-Studie".

Numerous forms of therapy exist for the increasing number of obese children and adolescents in Germany, but these are heterogeneous and have not been evaluated. Access to health care, long- and short-term treatment outcome, as well as factors determining success of therapy were examined for the first time using standardized instruments to measure somatic and psychosocial variables. A total of 1,916 children aged 8-16 years from 48 (5 rehabilitation, 43 outpatient) institutions were examined. Data were collected for height, weight, blood pressure, and lipid status before treatment started (t0), at the end of treatment (t1), and 1 year after completion of treatment (t2). Furthermore, psychosocial variables were documented using questionnaires for parents and children. The mean BMI-SDS (body mass index standard deviation score) reduction at t1 was -0.27 and 1 year later at t2 was -0.23 (per protocol analysis; intention to treat: t1=-0.24; t2=-0.06). Psychological health and quality of life, which were markedly impaired at the beginning, improved. However, physical activity, media consumption, and nutrition remained basically unchanged. A reduction in weight is associated with an improvement in cardiovascular risk profiles, and long-term behavior changes are possible. However, the institutions differed considerably in the percentage of follow-up examinations and in the weight reduction accomplished.

[Treatment of obesity in pediatric patients in Germany: anthropometry, comorbidity and socioeconomic gradients based on the BZgA Observational Study]. / Beobachtungsstudie der BZgA zur Adipositastherapie bei Kindern und Jugendlichen in Deutschland: Anthropometrie, Komorbidität und Sozialstatus.

BACKGROUND: In recent years, the prevalence of overweight and obesity in children and adolescents has markedly increased. Even though numerous treatment options are available for patients, these are heterogeneously structured and insufficiently evaluated. PATIENTS: In this initial report of specific therapy under routine care circumstances, data from 1916 patients aged 8-16.9 years were analyzed. Patients were characterized based on cluster of therapy, sociodemographic, psychosocial and medical features. Furthermore, the quality of care procedures with regard to the diagnosis of comorbidities was analyzed. RESULTS: At initial medical examination mean patient BMI-SDS was +2.43 and mean age was 12.6 years. 43.3% of patients were male. The mean duration of treatment was 6.1 months (55% outpatient, 45% inpatient care setting). 14% of patients were overweight, 48% obese and 37% were extremely obese. In 51% of the patients we could find already comorbidities. Parental BMI was related to patient's BMI. Socioeconomic status was reduced compared to general population. CONCLUSION: In this nationwide, pioneer multicentre observational study initiated by Federal Centre for Health Education (BZgA) in Germany, different therapeutic approaches were compared by examining somatic and psychosocial variables. The short- and long-term effects of different weight reduction programs on BMI-SDS, nutritional- and physical activity habits as well as quality of life and comorbidity will be examined at the end of therapy. Two follow-up assessments are planned for one and two years after the intervention ended.

Medical care of overweight children under real-life conditions: the German BZgA observation study.

OBJECTIVE: Current care for overweight children is controversial, and only few data are available concerning the process of care, as well as the outcome under real-life conditions. METHODS: A nationwide survey of treatment programs for overweight children and adolescents in Germany identified 480 treatment centers. From 135 institutions that had agreed to participate in this study of process of care and outcome, 48 randomly chosen institutions were included in the study. All 1916 overweight children (mean age 12.6 years, 57% female, mean body mass index 30.0 kg/m(2)), who presented at these institutions for lifestyle interventions, were included in this study. Diagnostic procedures according to guidelines and effect of lifestyle interventions on weight status at end of treatment were analyzed. RESULTS: Children treated <3 months were older and more obese, whereas children with >3 months treatment duration demonstrated more cardiovascular risk factors at baseline. On the basis of an intention-to-treat analysis, 75% of the children reduced their overweight. The reduction of overweight varied widely between the treatment institutions (intracluster correlation coefficient 0.15 in the multiple regression model reflecting the intracenter correlation). Screening for hypertension, disturbed glucose metabolism and dyslipidemia was performed in 52% of the children at baseline and in 10% at the end of intervention. CONCLUSION: Overweight reduction is achievable with lifestyle intervention in clinical practice. However, because the clientele, treatment approach and outcome varied widely between different institutions, and screening for comorbidities was seldomly performed as recommended, quality criteria for institutions have to be implemented to improve medical care of overweight children under real-life conditions.

[Obesity in children and adolescents and their parents. Correlation of standardized body mass index between patients, their parents and siblings from the multicentre APS data]. / Adipositas bei Kindern, Jugendlichen und ihren Eltern. Assoziation des standardisierten BMI zwischen Patienten, Eltern und Geschwistern anhand multizentrischer APV-Daten.

BACKGROUND: Obesity in children and adolescents is moving into the focus of public interest. Genetic as well as environmental factors are important in the etiology of obesity. The aim of this multicentre study was to correlate the weight of overweight or obese children and adolescents with that of their parents and siblings. PATIENTS AND METHODS: Anthropometric and other data - comorbidities, various influencing factors and treatment - were collected from the adiposity data acquisition system for prospective surveillance (APS). Currently 125 medical centers and pediatric care clinics in Germany, Austria and Switzerland use the APS documentation. Until February 2008 data on a total of 37,062 children and adolescents had been collected. RESULTS: Data to calculate the Body Mass Index (BMI) were obtained from both parents of 11,074 (29,9%) children and adolescents. The mean BMI Standard Deviation Score (SDS) of these children and adolescents was 2.46. Their mean age was 11.9 years; 46% were males. The mean BMI-SDS of these children and adolescents correlated significantly with the BMI-SDS of both the mother (r=0.29 [Spearman's rank correlation coefficient]) and the father (r=018, both p<0.0001). The correlation with the father's BMI was closer in adolescents (15-20 years, r=0.20) than in young children (<10 years: r=0.12). The correlation with the mother's BMI was independent of age. A multivariate model including the BMI of the parents as well as age and sex of the children and adolescents explained 10.0% of the variance. Significant influencing factors were BMI of the mother, sex and the relationship between BMI of mother, age and sex. Data for the BMI of siblings were available of 3,933 (10.6 %) children and adolescents. The correlation of the BMI of the children and adolescents with that of their siblings was +0.17 (p<0.0001). This correlation was highest in adolescence (<10 years.: r=0.17, 15-20 years.: r=0.24, both p<0.0001). CONCLUSION: The patient's weight correlated more strongly with the mother's than the father's weight or that of the siblings.

Comparison of transvaginal ultrasound, hysteroscopy, and dilatation and curettage in the diagnosis of abnormal vaginal bleeding and intrauterine pathology in perimenopausal and postmenopausal women.

STUDY OBJECTIVE: To compare transvaginal ultrasound, hysteroscopy, and dilation and curettage (D&C) in the evaluation of women with perimenopausal and postmenopausal bleeding. DESIGN: Descriptive study (Canadian Task Force classification II-1). SETTING: Seven outpatient clinics. PATIENTS: One thousand two hundred eighty-six women. INTERVENTION: Transvaginal ultrasound, hysteroscopy, and D&C. MEASUREMENTS AND MAIN RESULTS: Of our patient population, 29 (2.26%) had a histologic diagnosis of endometrial carcinoma; in 2 of them (7.14%) endometrial thickness was 5 mm or less. In 10 women (34.5%), endometrial carcinoma was missed by hysteroscopy (sensitivity 65.52%, specificity 99.92%). Complication rate of D&C was 1.4%. CONCLUSION: In women with perimenopausal and postmenopausal bleeding neither transvaginal ultrasound nor hysteroscopy as a single diagnostic tool is suitable to rule out endometrial cancer.

Expression and functional analysis of endothelial nitric oxide synthase (eNOS) in human placenta.

We have investigated the expression and localization of endothelium-derived nitric oxide synthase (eNOS) and the effect of eNOS on placental human chorionic gonadotrophin (HCG) release. eNOS mRNA was found to be expressed in all tissues, with its expression significantly (P<0.05) increased across gestation. Compared to normal term gestation, placentae from term pregnancies with fetal retardation, or maternal diabetes, but not with maternal hypertension, displayed significantly more (P<0.05) eNOS mRNA. By immunocytochemistry, we found staining for eNOS in both the cyto- and syncytiotrophoblasts of first trimester and a loss of cytotrophoblast eNOS staining in term placentae, while syncytiotrophoblasts at term were strongly eNOS positive. Additional staining was found in endothelium surrounding the vascular tree. HCG was found to colocalize with eNOS in trophoblasts, but not in endothelia. When placental explants were perifused, exposure to the NOS substrate, the NO donor, I-arginine and trinitroglycerol evoked a prompt, albeit transient, increase of HCG release. The NOS inhibitor delayed, but did not block arginine-induced HCG release. Thus, eNOS is expressed in the human placenta at increasing levels during gestation with further increases during some pathological conditions. A role for NO in the acute endocrine modulation of the placenta is suggested by the colocalization of eNOS with HCG in human trophoblasts and the prompt secretion of HCG in response to agents which increase NO concentrations.
