In summary, our study describes an influence of SAT topography on adiponectin serum levels and provides first evidence that incipient atherosclerosis is associated with low serum levels of this adipocytokine.

OBJECTIVE -To estimate the impact of type 1 diabetes during pregnancy on transgenerational genetically caused and/or fuel-mediated amplification of types 1 and 2 diabetes and to estimate the impact of elevated amniotic fluid insulin levels. RESEARCH DESIGN AND METHODS-A total of 75 white offspring of type 1 diabetic mothers and 49 control subjects of similar age and pubertal stage were examined at 5-15 years of age. All offspring had an oral glucose tolerance test. Glucose, insulin, and C-peptide were measured at 0, 30, 60, and 120 min after loading. Lipids and autoimmune antibodies were measured in fasting plasma.RESULTS -Of the 75 offspring, 4 (5.3%) had overt diabetes, and 16 of 71 (22.5%) had autoimmune antibodies. Offspring of diabetic mothers had significantly higher BMI; symmetry indexes; cholesterol, glucose, insulin, and C-peptide levels; and insulin resistance than control subjects. With the exception of cholesterol, these values were significantly elevated in offspring who had elevated amniotic fluid insulin levels (Ͼ8 µU/ml, Ͼ48 pmol/l) during pregnancy compared with normoinsulinemic offspring and control subjects.CONCLUSIONS -Offspring of type 1 diabetic mothers have an increased risk for diabetes later in life. The relative risk for type 1 and type 2 diabetes is 71.6 and 3.2, respectively. Type 2 diabetes-associated risk factors, such as high BMI; elevated glucose, insulin, and C-peptide levels; and insulin resistance, are related to the fetal metabolic experience in utero, as reflected by amniotic fluid insulin concentration.

A low grade inflammation as determined by serum hs-CRP is significantly increased in children with type 1 diabetes, and even more pronounced in apparently healthy juveniles with obesity. The increased IMT of CCAs strongly argues for an association between this low grade inflammation and early atherosclerotic vessel injury.

OBJECTIVE:To investigate the effect of short term energy restriction combined with physical activity on serum concentrations of Interleukin-6 (IL-6) in obese children and adolescents. DESIGN: Longitudinal intervention study of 3.8 -5 MJ daily with exercise. SUBJECTS: Forty-nine white obese children and adolescents (31 girls, age 11.9 AE 1.8 y; 18 boys, age 11.6 AE 1.7 y). MEASUREMENTS: Indexes of obesity, IL-6, leptin, estradiol, systolic and diastolic blood pressure, heart rate at baseline and after 3 weeks. RESULTS: All determined parameters decreased significiantly during the 3 week program (IL-6: 3.9 AE 4.7 vs 2.0 AE 2.2 pg=ml; P < 0.05). Body mass index (BMI) fat mass, percentage fat mass (indexes of obesity), and leptin were not related to IL-6 before the program. In contrast, IL-6 concentrations correlated significantly with indexes of obesity and leptin after weight loss. IL-6 concentrations did not correlate with estradiol, systolic and diastolic blood pressure, and heart rate. Changes in IL-6 concentrations correlated significantly with changes in BMI (r ¼ 0.25, P < 0.05). CONCLUSION: An improved body composition induced by restriction of energy intake and increase in physical activity is associated with more favorable serum concentrations of IL-6 in obese children and adolescents.
