Effect of Diet and Physical Activity on Adipokines

Study Overview
=================
Brief Summary
-----------------
The prevalence of metabolic syndrome (MetS) in young population continues to rise. Obesity is a chronic inflammatory disorder in which leptin, adiponectin and C reactive protein (CRP) play an important role. This study aimed to determine whether these adipokines are significant markers in defining MetS in pediatric population and to assess the effect of hypocaloric diet and physical activity on serum concentrations of adiponectine, leptin, and high sensitivity CRP (hs-CRP).

Detailed Description
-----------------
The idea that adipose tissue is just a form of energy storage has changed dramatically in recent years. Currently, adipose tissue is considered to be a true endocrine gland that fulfills multiple roles in regulating different biological functions. Communication between adipose tissue and the rest of the systems is accomplished through bioactive mediators (adipokines) Adipokines control energy homeostasis and are involved in metabolic, endocrine and immunological processes.The prevalence of metabolic syndrome (MetS) in young population continues to rise. Obesity is a chronic inflammatory disorder in which leptin, adiponectin and C reactive protein (CRP) play an important role. This study aimed to determine whether these adipokines are significant markers in defining MetS in pediatric population and to assess the effect of hypocaloric diet and physical activity on serum concentrations of adiponectine, leptin, and high sensitivity CRP (hs-CRP). The investigators tested the hypothesis that long-term lifestyle changes and moderate weight loss would reduce the plasma concentrations of adipokines involved in inflammation, angiogenesis, and chemotaxis and would increase adiponectin concentrations. Material and methods: A prospective study was conducted over a period of 1 year, between January 2016 and December 2016, on 66 cases of obesity in children diagnosed at the Louis Ţurcanu Emergency Hospital for Children Timisoara. The patients diagnosed with MetS were put on diet and physical exercise for 3 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Defining obesity in the pediatric population | Measuring weight in kilograms and height in meters in order to calculate BMI and represent it on the percentile graph. | Weight and height were measured on day 1 of admission. Obesity was defined as a BMI > the 95th percentile. | 
| Leptin changes in the obese children with metabolic syndrome | Evaluating leptin in the obese group with metabolic syndrome after three months of diet and physical activity. | Leptin levels were measured on day 1 of admission and after three months. Normal range was considered < 24ng/ml. | 
| Adiponectin changes in the obese children with metabolic syndrome | Evaluating adiponectin in the obese group with metabolic syndrome after three months of diet and physical activity. | Adiponectin levels were measured on day 1 of admittance and after three months in children aged between 4 and 18 years. Levels 4-26 mcg/ml were defined as normal values. | 
| hsCRP changes in the obese children with metabolic syndrome | Evaluating hsCRP in the obese group with metabolic syndrome after three months of diet and physical activity. | hsCRP levels were measured on day 1 of admittance and after three months in children aged between 4 and 18 years. Normal levels were considered between 0.1-2.8 mg/l. |
