Ethnicity and cardiovascular risk factors: evaluation of 40,921 normal-weight, overweight or obese children and adolescents living in Central Europe.

BACKGROUND AND AIMS: Cardiovascular disease (CVD) is a major global health problem and the leading cause of death in Europe. Risk factors such as obesity and hypertension that accelerate the development of CVD begin in childhood. Ethnicity is a known risk factor for CVD in adults. The aim of this study is to explore differences in the prevalence of hypertension and dyslipidemia among overweight/obese and normal-weight children/adolescents of three different ethnic origins living in Central Europe. METHODS AND PROCEDURES: Prevalence of hypertension and dyslipidemia was calculated among obese/overweight children/adolescents (n = 25,986; mean age 12.7 ± 3.0 years; range: 0-18 years; 46% males) documented in the German-Austrian-Swiss APV (Prospective Documentation of Overweight Children and Adolescents) registry and among normal-weight subjects (n = 14,935; mean age: 8.8 ± 5.1 years; range 0-18 years; 51% males) from the population-based cross-sectional German Health Interview and Examination Survey for Children and Adolescents (KiGGS) study. In both cohorts, subjects were categorized into three ethnic groups (Central European: Germany, Austria, Switzerland; Southeastern European: Turkish; Southern European: Spain, Portugal, Italy, Greece, Cyprus, Malta) based on the country of birth of both parents. Regression models were used to examine ethnic differences after adjustment for age and gender and body mass index (BMI) category. RESULTS: Age-, gender- and BMI category-adjusted prevalence of hypertension were 38% and 39% for the ethnic minority groups, compared with 35% among German/Austrian/Swiss counterparts. Turkish ethnicity was significantly associated with hypertension (odds ratio (OR) 1.14; 95% confidence interval: 1.02-1.27; P = 0.0446). No significant ethnic differences were found in lipid levels. Prevalence of hypertension found among normal-weight subjects (Central European vs Southeastern vs Southern European: 6.8% vs 6.3% vs 7.2%) did not differ significantly. CONCLUSIONS: Turkish obese/overweight children/adolescents showed a significantly higher prevalence of hypertension relative to their peers of Central European descent. No significant ethnic difference in the prevalence of hypertension was found among normal-weight children/adolescents. The high prevalence of hypertension among Turkish obese/overweight children/adolescents indicates the need for greater preventive and therapeutic efforts to reduce cardiovascular risk factors among vulnerable populations.

[Childhood craniopharyngioma with hypothalamic obesity - no long-term weight reduction due to rehabilitation programs]. / Kraniopharyngeom mit hypothalamischer Adipositas - Stationäre Rehabilitation ohne Einfluss auf die Gewichtszunahme bei Kindern und Jugendlichen.

BACKGROUND: Severe obesity due to hypothalamic involvement has major impact on prognosis in long-term survivors of childhood craniopharyngioma. The long-term effects of rehabilitation efforts on weight development and obesity in these patients are not analyzed up to now. PATIENTS AND METHODS: 108 patients with childhood craniopharyngioma recruited in HIT Endo before 2001 were included in the study. Long-term weight development (BMI SDS after >10 yrs follow-up) was analyzed in regard to rehabilitation, which was performed in 31 of 108 (29%) patients (one rehabilitation in 4 patients (13%), more than one in 21 patients (68%), 6 patients unknown) in 13 German rehabilitation -clinics. RESULTS: 84% of patients underwent rehabilitation in order to reduce hypothalamic obesity (BMI>+ 2 SD), whereas 12% of patients were normal weight. Childhood craniopharyngioma pa-tients with rehabilitation presented with higher BMI at diagnosis (median BMI: +1.32 SD; range: -1.08 to + 7.00 SD) and at last evaluation (median BMI: +4.93 SD; range: -0.20 to + 13.13 SD) when compared with patients without rehabilitation (median BMI at diagnosis: +0.24 SD; range: -2.67 to + 6.98 SD; BMI at evaluation: +2.09 SD; range: -1.48 to + 10.23 SD). A long-term weight reducing effect of rehabilitation was no detectable regardless of degree of obesity, frequency of rehabilitation, and hospital of rehabilitation. CONCLUSION: Treatment options for hypothalamic obesity in terms of rehabilitation are limited. Accordingly, strategies for prevention of hypothalamic lesions and psychosocial effects of rehabilitation are currently in focus for improvement of prognosis in childhood craniopharyngioma patients.

Association of foveomacular retinitis, ankylosing spondylitis, iritis, and acquired iris atrophy.

A case of foveomacular retinitis, ankylosing spondylitis, iritis, and iris dissociation is described. Only ankylosing spondylitis was present in other family members. The differential diagnosis is discussed. The iritis of ankylosing spondylitis must be considered in cases of developmental full-thickness iris holes.
