RESUMO
Background: Metabolically obese normal-weight [MONW] children and adolescents are characterized by body mass index [BMI] lower than +1SD with metabolic disorders such as hyperglycemia, hypertriglyceridemia, and/or hypertension. This study wants to determineprevalence of MONW, metabolically benign normal weight [MBNW], metabolically abnormality obese [MAO] and comparethe components of metabolic syndrome [MetS] in some Iranian normal-weight children and adolescents in Ahvaz, Iran
Methods: This cross-sectional study was conducted on 1124 boys and 1128 girls, aged 10-18 y, Ahvaz, Khuzestan.Participants were selected from 6 health centers in Ahvaz by a multistage cluster random sampling method. The Mets was defined according to the modified Adult Treatment Panel III [ATP III]. Anthropometric measurements and blood pressure were measured according to standard protocols. Fasting blood samples were collected for biochemical assessment
Results: MetS prevalence in normal weight group was 5.4% and 1.45% in boys and girls, respectively [P = 0.001] showing a significant difference. Triglyceride abnormality percentages [MBNW = 23.9%, MAO = 88.8%, MONW = 91%] and high density lipoprotein [MBNW = 19.2%, MAO = 73.8% and MONW = 67.2%] were higher than other MetS components in these groups
Conclusions: Since BMI in children and adolescents with metabolically obese-normal weight is normal the continuous measurements and treatment of MetS components especially in boys are important from public health view. The components mean of MetS was higher in MONW and MAO individuals compared with MBNW
RESUMO
Hepatitis B Virus infection [HBV] is a significant hazard in the dental environment and endoscopy room because the virus may be transmitted through contaminated instruments. This study was conducted in order to detect the HbsAg in the endoscopy and dental equipments and then to compare the results. In this cross-sectional study, in a time period of 30 days, 100 and 50 specimens were obtained randomly from multiple apparently sterile dental equipments and endescopes, respectively. Obtained samples evaluated for HBsAg by ELISA method [Sorin biomedical Kit]. Results of the present study shows that 2% of instruments used for dental treatment was infected with hepatitis B virus. Among 50 specimens of endescope instruments, only one sample was positive for HBsAg. Upon our results, there might exist the possibility of HBV transmission through dental equipments and endoscope instruments. We advise the use of standard sterilization for prevention of transmission of hepatitis B virus infection
