[Prevalence of obesity, abdominal obesity and hypertension in 10-13 years old children of governmental and non-governmental elementary school in some regions of Tehran in 1390 year]

Obesity and hypertension disorders affect whole body and are associated with most diseases, including diabetes and cardiovascular disease. Children with obesity and high blood pressure are prone to adulthood health problems. Yet most parents are unaware of their child obesity and high blood pressure. This 2011 study, included 1184 boys and girls aged 10-13 years old from five districts of Tehran. Overweight and obesity were diagnosed by the International Obesity Task Force [IOTF] criteria. Also, systolic or diastolic blood pressure >/= 95 for age, height and gender were considered as hypertensive. Waist circumference according to the standard Iranian cut off for children was assessed on the basis of age, gender. Waist circumference > 90 percentile was considered as abdominal obesity. Prevalences of overweight, obesity, hypertension and abdominal obesity were 21.92, 5.28, 13.16 and 25.31% respectively. The highest prevalence of obesity and abdominal obesity reported in District 3, which is north of Tehran and the lowest was related to boys from region 19 of southern Tehran. Economic conditions can affect obesity and hypertension disorders and more attention must be paid to obesity and hypertension in particular, to creat awarences in parents for changes in lifestyle, nutrition and physical activity these children

[Comparing the glycemic index and some nutrient contents of two types of imported rice with a domestic rice]

Carbohydrate contents of different foods may have different effects on postprandial blood glucose. This study was done to measure and compare glycemic indices and some nutrients in three types of rices. This study was conducted to compare the glycemic effects of 50g carbohydrate in the Basmati, Kazemi and Sorna Perl types of rice in normal subjects. Thirty healthy subjects [13 male and 17 female], aged between 20-40 years, were selected, and were evaluated 4 times at 1 week intervals. On the first day, all subjects consumed 50 gram glucose; they were then divided into 3 groups. Each group consumed one of the 3 rice types, with 50g carbohydrate content each week. Blood samples were collected before and at 15,30,60 and 120 minutes, after taking glucose and rice. At the end of the experiment, all subjects received all three kinds of rice and the Gl was calculated for each rice as the ratio of the incremental area under the 3- hour glycemic response curve to rice, to the incremental area under the 3- hour glycemic response curve to sugar. The glycemic indices of Sorna Pearl, Kasemin and Basmati were 52/2 +/- 5/1, 67/6 +/- 13 and 61/2 +/- 6/1 respectively, the Gl of Sorna peri being lower than the others [p<0/05]. Maximum changes of blood sugar for Sorna Perl, Kasemi and Basmati were 21/8112, 27/4 +/- 6 and 31/7 +/- 5/9 mg/dl respectively. The results of this study indicate that in healthy of the 3 types of rice consumed subjects Sorna Perl had the lowest Gl and GL
