The Relationship

The objective of this work was to study the relationship between the serum adiponectin level on the one hand, and the age, stage of sexual development and main anthropometric characteristics of children and adolescents depending on the degree of obesity, the presence or absence of metabolic disorders on the other hand. A total of 111 children and adolescents at the age from 2.5 to 17.9 years were available for the examination including 56 presenting with "simple" constitutional exogenous obesity, 12 overweight patients, and 43 with normal body weight. The concentration of adiponectin in the serum of obese children and adolescents was lower than in those with normal body weight (p=0.009). The highest adiponectin level was documented in prepubertal children; it decreased progressively in the course of sexual development and negatively correlated with BMI, waist circumference---???---(WC), and BMI SDS. The children presenting with obesity complicated by insulin resistance, the serum adiponectin level was lower than in those having normal and stimulated immunoreactive insulin concentrations, HOMA-IR and Matsuda's ISI indices. The study revealed the relationship between serum adiponectin levels, concentrations of high density lipoprotein cholesterol and triglycerides. The data obtained give reason to conjecture that the reduction of serum adiponectin level may be a link connecting obesity, insulin resistance, and atherogenic changed in the serum developing as early as the childhood that can be used as an additional biomarker for the identification of a group of children and adolescents at high risk of complications associated with obesity.

Abstract Background Obesity has emerged as a public health crisis in many populations including Egypt. Adipose tissue produces a number of adipokines, one of them is adiponectin which has attracted much attention because of its antidiabetic and antiatherogenic effects. Objective To determine the effect of a weight loss program on serum adiponectin level and insulin resistance among overweight and obese adult premenopausal females. Study design A pre-postintervention study was carried out among 95 premenopausal overweight and obese females (body mass index ≥ 25 kg/m2) aged 20 to 40 years at the integrated health clinic affiliated to the High Institute of Public Health, Alexandria, Egypt, from February 2016 to February 2017. All participants underwent a weight loss program based on a reduced calorie balanced diet and advised to increase their physical activity. Dietary instructions and follow-up were done weekly throughout 16 weeks. Blood samples were collected to investigate serum adiponectin level and insulin resistance at the beginning and the end of the intervention. Results After 16 weeks, a significant decrease in body weight by 9.7% was associated with a significant increase in serum adiponectin from 13.3 ± 4.9 μg/ml to 18.5 ± 5.6 μg/ml. Both fasting insulin and insulin resistance had decreased significantly by 13.6% and 13.7%, respectively. Conclusion A weight reduction program depending on a reduced calorie diet for 16 weeks was associated with a significant increase in total adiponectin level and reduction in insulin resistance. An emphasis on the importance of keeping normal weight through nutritional education and the promotion of healthy diets is recommended to reduce the risk of occurrence of insulin resistance, type 2 diabetes, and cardiovascular diseases.

Background: Obesity is the main risk factor for essential hypertension (EH) in childhood. The O.Si.Me. study (Obesity and Metabolic Syndrome in children and adolescents) evaluated the prevalence of metabolic syndrome (MetS) and its constitutive traits in a sample of obese children and adolescents living in Campania, southern Italy. Patients and methods: Four hundred and fifteen children and adolescents consecutively referred to the National Health Service participating Outpatient Clinics for minor health problems and found to have a Body Mass Index (BMI) Z-score > 2.0 were enrolled in the study. The entire sample was screened for MetS, which was defined as the presence of at least 2 of the following alterations in addition to obesity: fasting hyperglycemia, low levels of high-density lipoproteins cholesterol, hypertriglyceridemia, and EH. The present analysis evaluated the clinical characteristics of the O.Si.Me subgroup of EH participants (systolic and/or diastolic BP ≥ 95 th percentile for age, gender and height) as compared with normotensive participants. Results: The prevalence of EH in the O.Si.Me population was 23.6 % (98/415, 48M and 50F.) and two-thirds of the EH participants met the MetS diagnostic criteria. The EH participants featured serum insulin and HOMA-IR levels significantly higher compared with normotensive ones (11.6±0.6 vs. 9.5±0.4 μIU/ml, p = 0.014; 2.6±0.1 vs. 2.2±0.1, p = 0.028 for insulin and HOMA-IR, respectively). These differences were common to boys and girls and remained significant after correction for age, pubertal stage, body weight, length, BMI, gestational age at birth, duration of breastfeeding and anthropometric parental parameters. Accordingly, children and adolescents with EH had a a relative risk of being insulin resistant (defined as a HOMA-IR ≥2.5) significantly greater compared to those without. Moreover, they exhibited higher serum creatinine levels (53.8±7.1 vs. 35.4±6.8 μmol/l, p=0.025) accounting for gender and body weight. Conclusions: More than a quarter of obese children and adolescents meet the diagnostic criteria for EH in the Campania region in southern Italy. These obese boys and girls have an increased prevalence of insulin resistance and apparently an initial reduction in renal function compared with obese children and adolescents with normal BP.

It has been reported that the serum adiponectin level was negatively correlated with body mass index (BMI), insulin resistance index, and triglycerides and was positively correlated with high-density lipoprotein cholesterol in several cross-sectional studies. However, the causal relationship has not been elucidated. We investigated whether the baseline adiponectin level could predict subsequent changes in insulin resistance, lipid profile, or body weight in a 2-yr longitudinal study. This study included 590 male Japanese subjects, aged 30–65 yr, who received annual health checkups in both 2000 and 2002. Blood pressure, heart rate, and anthropometric and metabolic parameters, including serum insulin and adiponectin levels, were determined. The insulin resistance index was calculated based on homeostasis model assessment. Baseline adiponectin level was not correlated with the subsequent change in lipid profile or BMI in 2 yr after adjustment for each baseline value. However, the baseline adiponectin level was negatively correlated with subsequent changes in insulin and insulin resistance index based on homeostasis model assessment, even after adjustment for change in BMI (r = −0.162 and r = −0.140, respectively). These findings suggest that the serum adiponectin concentration predicts subsequent changes in insulin resistance, but not in lipid profile or body weight.

The  aim  of  the  observational  case  control  study  was  to  find  out  the  association  of  type  2  diabetes  mellitus  (T2DM)  with  serum  adiponectin  level  in  Bangladeshi  population.  This  was  conducted  in  the  Biomedical  Research  Group,  Research  Division,  Bangladesh  Institute  of  Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM), Dhaka,  Bangladesh.  Sixty six T2DM subjects and seventy four healthy control subjects were included.  Diabetes  was  diagnosed  and  classified  as  per  World  Health  Organization  criteria.  Serum  adiponectin was measured by Enzyme Linked Immunosorbent Assay (ELISA) method. Serum  glucose  was  measured  by  glucose-oxidase  method;  serum  insulin  was  measured  by  chemiluminescence- based ELISA technique. The insulin secretory capacity (HOMA%B), insulin  sensitivity  (HOMA%S)  &  insulin  resistance  (HOMA-IR)  were  assayed  by  homeostasis  model  assessment method. Statistical analysis was performed using SPSS Windows version 11.5. The  median  (range)  fasting  serum  insulin  of  control  and T2DM subjects  were  14.7  (1.9-45.9)  and  18.1 (4.1-42.8), respectively. The median (range) serum adiponectin (?g/ml) of the control and  T2DM  subjects  were  8.7  (0.8-16.0)  and  6.2  (1.1-22.4).  The  serum  adiponectin  of  T2DM  was  significantly lower than the control subjects (p < 0.001). The median (range) HOMA%B values  of control and T2DM subjects were 160.1 (33.4-493.4) and 100.5 (17.7-349.3), respectively. The  median  HOMA%B  of  T2DM  subjects  was  significantly  lower  than  the  control  subjects  (p  <  0.001).  The  median  (range)  HOMA%S  values  of  control  and  T2DM  subjects  were  44.2  (9.8-339.4)  and  32.8  (14.3-154.7),  respectively.  The  median  HOMA%S  of  T2DM  group  was  significantly lower than the control subjects (p < 0.05). The median (range) HOMA-IR of control  and T2DM subjects were 3.5 (0.5-11.4) and 5.8 (1.0-28.3), respectively. The median HOMA-IR  of T2DM subjects was significantly higher than the control subjects (p < 0.001). The results of  the  study  suggest  that  T2DM  subjects  have  both  insulin  secretory  defects,  insulin  resistance  and associated with lower serum adiponectin level in Bangladeshi population.Mediscope Vol. 2, No. 2: July 2015, Pages 16-21

Background: One of the objective methods of assessing the level of cardiopulmonary capacity in overweight and obese children and adolescents is cardiopulmonary exercise testing (CPET).Aims: The purpose of present study is an evaluation of aerobic capacity in high body mass index (BMI) children and adolescents by comparing them with a normal weight control group by CPET.Methods and Procedures: The subjects were recruited from participants of the Program of Treatment for Overweight and Obese Children organized by a local pediatric rehabilitation center in Poland. Based on BMI for age and gender, two validation groups were selected: (1) a group of overweight children (n = 49) and (2) a group of obese children (n = 48). The study included also 53 normal weight participants as a reference group (REF). The study consisted of two parts: anthropometric measurements and CPET. The Godfrey protocol for CPET was applied.Outcomes and Results: In this study, obese children and adolescents showed similar absolute VO2peak values in liters per minute (1.64 L/min) compared to overweight children (1.48 L/min), but significantly higher than children with normal body weight (1.39 L/min). The obese children and adolescents presented lower VO2peak in relation to body weight (25.44 ml/kg/min) compared to their peers with normal body weight (36.5 ml/kg/min), and overweight children (29.18 ml/kg/min).Conclusion and Implications: The main finding of our study was recognition of significant differences between cardiopulmonary capacity parameters in obese children in comparison not only to normal weight peers, but to overweight, too.

Background. Higher levels of uric acid production have been reported in individuals with visceral fat obesity, and obesity is known to enhance xanthine oxidoreductase (XOR) activity, although the precise mechanism remains unclear. We investigated the associations of visceral fat area (VFA), serum adiponectin level, and insulin resistance with plasma XOR activity using our novel highly sensitive assay based on [13C2,15N2] xanthine and liquid chromatography/triple quadrupole mass spectrometry. Methods. This cross-sectional study included 193 subjects (92 males and 101 females) registered in the MedCity21 health examination registry. Plasma XOR activity, serum adiponectin level, and VFA obtained by computed tomography were measured, and insulin resistance was determined based on the homeostasis model assessment (HOMA-IR) index. Results. The mean values for VFA, log HOMA-IR, and log plasma XOR activity were 76.8 ± 45.8 cm2, 0.14 ± 0.30, and 1.50 ± 0.44 pmol/h/mL, respectively. Multiple regression analysis showed that HOMA-IR was significantly (p=0.020) associated with plasma XOR activity independent of other factors, including VFA and adiponectin level, as well as age, sex, alcohol drinking habit, smoking habit, alanine transaminase, HbA1c, and eGFR. The “sex∗HOMA−IR” interaction was not significant (p=0.89), indicating that sex difference does not have an effect on the relationship between HOMA-IR and plasma XOR activity. Conclusions. Our results indicate that insulin resistance is associated with plasma XOR activity and that relationship is independent of visceral adiposity and adiponectin level, suggesting that the development of insulin resistance resulting from increased visceral adiposity and/or reduced serum adiponectin contributes to increased uric acid production by stimulating XOR activity.

Abstract Background: Several studies have evaluated the association between the serum adiponectin level and knee and hand osteoarthritis (OA); mixed results have been reported. We investigated the relationship between OA and the serum adiponectin level according to the radiographic features of knee and hand OA.Methods: A total of 2,402 subjects was recruited from the Dong-gu Study. Baseline characteristics were collected via a questionnaire, and X-rays of knee and hand joints were scored using a semi-quantitative grading system. The relationship between the serum adiponectin level and radiographic severity was evaluated by linear regression analysis.Results: Subjects in the higher serum adiponectin level tertiles were older and had a lower body mass index (BMI) than those in the lower tertiles. Regarding knee joint scores, the serum adiponectin level was positively associated with the total score (P < 0.001), osteophyte score (P = 0.003), and joint space narrowing (JSN) score (P < 0.001) after adjustment for age, gender, BMI, smoking, alcohol consumption, education, and physical activity. In terms of hand joint scores, no association was found between the serum adiponectin level and the total score, osteophyte score, JSN score, subchondral cyst score, sclerosis score, erosion score, or malalignment score after the above-mentioned adjustments.Conclusion: An increased serum adiponectin level was associated with a higher radiographic score in the knee joint, but not in the hand joint, suggesting the involvement of different pathophysiologic mechanisms in the development of OA between those joints.

Adiponectin, which is secreted specifically by adipose tissue, has been shown to act as an anti-atherosclerotic protein by direct effects on endothelial cells. Clinical studies have shown that adiponectin levels are lower in individuals with obesity, diabetes and coronary artery disease. The present study investigated relationships between serum adiponectin levels and body mass index (BMI), blood pressure, insulin resistance index, lipid profile, uric acid and high-sensitivity C-reactive protein levels in a large number of Japanese subjects not taking any medication for metabolic disease and without severe illness (705 men and 262 women; age 30–65 years; BMI 22.5±2.9kg/m2). The serum adiponectin concentration was measured by ELISA, without a protein-denaturing step. The insulin resistance index was assessed by homoeostasis model assessment (HOMA-IR). The serum concentration of adiponectin in women (13.5±7.9μg/ml) was significantly higher than that in men (7.2±4.6μg/ml). The serum adiponectin level was negatively correlated with BMI, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, insulin, HOMA-IR, total cholesterol, triacylglycerols, low-density lipoprotein (LDL)-cholesterol and uric acid, and positively correlated with high-density lipoprotein (HDL)-cholesterol. The correlations between serum adiponectin level and insulin, HOMA-IR, triacylglycerols, HDL-cholesterol, LDL-cholesterol and uric acid were significant even after adjustment for age, sex and BMI. Stepwise multiple regression analysis revealed that HDL-cholesterol, sex, BMI and HOMA-IR were independently correlated with the serum adiponectin level (R2 = 0.377). These findings suggest that the serum adiponectin level is negatively correlated with HOMA-IR and positively correlated with HDL-cholesterol, independent of age, sex and BMI, in the Japanese population.
