The relationship between vitamin D deficiency and metabolic syndrome in obese individuals

Introduction: Decreased vitamin D levels may have a role in the development of metabolic syndrome due to its effect on the metabolic syndrome components or because of insulin resistance. Objectives: The aim of this study was to investigate the prevalence of vitamin D deficiency in obese individuals and to determine the relationship between deficiency of vitamin D with metabolic syndrome in obese people with metabolic syndrome and healthy individuals. Patients and Methods: In this descriptive-analytical study, samples were selected among obese individuals admitted to Hajar and Kashani hospitals in Shahrekord. Metabolic indices of the samples were measured and recorded along with information such as demographic characteristics. According to the indices, the subjects (n=192) were divided into two equal groups of healthy obese and obese people with metabolic syndrome. Vitamin D levels were measured in both groups followed by determination of relationships between the vitamin D levels with metabolic syndrome and its indices. Results: The mean ages of the patients and healthy groups were 50.09 +/- 1.95 years and 52.57 +/- 2.05 years, respectively. The average serum vitamin D levels in the two groups showed a significant difference with significantly lower vitamin D levels in the metabolic syndrome group than those in the obese subjects (P 0.05)

Serum concentration of hs-CRP in obese individuals with and without metabolic syndrome and its association with parameters of metabolic syndrome

Introduction: Serum level of high sensitivity C-reactive protein (hs-CRP), as an inflammatory marker, can play a role in development of metabolic syndrome in obese individuals. Objectives: This study aimed to determine serum concentration of hs-CRP in obese patients with metabolic syndrome and determine the association of this factor with factors involved in the progression of metabolic syndrome. Patients and Methods: In this study, samples were selected by convenient method from obese patients, admitted to Kashani and Hajar hospitals (Shahrekord, Iran). First, based on NCEP-ATPIII-defined metabolic syndrome, parameters of metabolic syndrome and serum levels of vitamin D were measured and a questionnaire containing demographics was completed for each participant. Accordingly, the samples (n=192) were divided into two identical groups; obese individuals without metabolic syndrome (controls) and obese individuals with metabolic syndrome (case group). Hs-CRP levels were measured in both groups. Results: Serum level of hs-CRP in the case group was 17.58 +/- 1.40 mu g/mL and in the control group was 9.04 +/- 1.26 mu g/mL, which was significantly higher in the case group than the control group (P 0.05). Conclusion: Hs-CRP can be used for prognosis and early detection of patients at risk of metabolic syndrome
