Abstract

Background and Aim: Obesity in childhood can cause obesity and its related complications in adulthood. This study was aimed to determine the correlateion between obesity among female adolescents and its related complications of Tehran schools in 2011.

Materials and Methods: In this cross-sectional study, 810 female adolescents, aged 12-16 years old, studying in schools of Tehran University of Medical Sciences were selected using multi-stage random sampling. Height and weight of the participants were measured and their BMI calculated. Data were collected using a questionnaire. Validity and reliability of the questionnaire was confirmed using content validity and test-retest. Using BMI, the participants were categorized into obese(BMI>95 percentile for age and gender) and overweight(BMI between 85 and 95 percentiles for age and gender) individuals. Data were analyzed using the Chi-squared test, Fisher's exact test, ANOVA, and multivariate logistic analysis.

Results: The prevalence of overweight and obesity in our study were 4.4%(95% CI 4/2-6/4) and 14/1%(95% CI 10/25-15/3), respectively. There was a statistically significant relationship between obesity and TV watching(p<0.001).

Conclusion: Based on our findings, further investigations are recommended to determine factors affecting overweight.

Abstract
Background and Aim: Clostridium perfringens is one of the major agents of food poisoning in humans around the world. This study was accomplished to identify and track the toxins of Clostridium perfringens bacterium in some raw animal food origin products in Shahrekord.
Materials and Methods: In this study, 100 samples of traditional and commercial curd and 43 samples of beef and lamb meats were randomly collected from Shahrekord’s shopping center in 2014. Then to identify the bacteria in samples cultivation and polymerase chain reaction (PCR) method were used.
Results: In culture method no positive samples were isolated. However, frequency of Clostridium perfringens bacterium in traditional and commercial curd samples and beef and lambs samples have been reported as 6, 10, 25 and 13 percent using PCR method, respectively. Frequency of cpa, cpb, cpe, cpi and etx genes were detected in curd samples were 37.5, 25, 75, 12.5 and 12.5 percent respectively and in meat samples 62, 50, 75.5, 37.5 and 25 percent respectively. Statistically significant differences were observed between the prevalence of the bacterium in various samples and their isolated toxins (p < 0.05).
Conclusion: With attention to infection of above food samples to Clostridium perfringens and also its transfer by foodstuffs to human, it is necessary to reduce food pollution of this organism for of public health.
