Comparing the Amount of 25-Hydroxy Vitamin D3 Concentrated in Serum of Normal and Overweight/ Obese Women and Its Relation to Metabolic Syndrome

Background & Objective: The relationship between vitamin D3 and risk factors of metabolic syndrome is unclear. This study aimed to investigate the vitamin D3 kevel of women and its relation with metabolic syndrome risk factors. Materials & methods: A cross-sectional study conducted between 200 healthy women aged 20 to 50 in two groups of normal BMI (BMI=18.5-24.9 kg/m2) and overweight/obese group (BMI≥25 kg/m2) who did not use mineral and vitamin supplementation. A fasting blood sample after 10 to 12 hour collected for fasting blood glucose, triglyceride, HDL-cholesterol and vitamin D3(25 OH D3) and weight, height, waist circumference, systolic and diastolic blood pressure were measured. Results: The mean of 89 obese subjects and 76 normal weight ones were 36±9 years old. The mean of 25 hydroxy vitamin D3 was not significantly different between the two groups; 22.3±19.9 ng/ml for normal weight group and 16.5±11.4 ng/ml for the obese one (p=0.31). HDL-cholesterol (r=.25, p<0.05) and waist circumference (r=-.14, p<0.05) were related to vitamin D3 levels significantly which repeated after BMI (body mass index) adjustment Conclusion: The results indicated that although the total amount of vitamin D3 were not significantly different between the two groups but more than 80 percent of women in both groups were deficient in vitamin D3 which is a  noteworthy issue based on the findings of the study

Comparison The Activity Rate of Alpha-1 Antitrypsin in Obese with normal weight People

Background & Objective: Obesity is one of the most important global health priorities as far as it increases illnesses and disorders the life quality. Alpha-1-Antitrypsin (AAT) is the most abundant serum protease inhibitor and prevents tissue degradation through proteases. Hence, its defect or deficiency significantly increases the risk of various diseases. AAT may be involved in the development and complications of obesity. The present study then was performed to determine the activity of AAT in the obese people compared to those with normal weight. Materials & Methods: In this cross- sectional study, determining the AAT’s activity was performed through Trypsin-Inhibitor-Capacity (TIC) in healthy individual who were referred to the laboratory of Dr.Shariati in Fasa Hospital in April 2013. Serum of 150 people with normal weight (Body Mass Index, BMI, ranges between 18.5 and 24.9) and the serum of 140 obese people (BMI more than 30) were surveyed. The data were analyzed by SPSS software using t-test and Pearson correlation coefficient. Results: The serum amount of TIC in obese people (1.774±0.618 µmol/min/ml) was significantly lower than its amount in people with normal weight (3.047±0.498 µmol/min/ml) (P-value< 0.001). There was a significant negative correlation between TIC and weight (P< 0.001, R=-0.686). In addition, no significant correlation was observed between TIC and age sex and height. Conclusion: The results showed that AAT in obese people was less in healthy individuals compared with the ones with normal weight. Therefore, it can be stated that AAT can be introduced as a clinical biomarker and be a potential target for treating obesity
