Background & Objective : Nutritionists have traditionally recognized breakfast as the most important meal of the day. The importance of eating breakfast is for growing and nutritional well being of children. While health habits such as eating breakfast, maintaining weight, and sleeping regularly are related to the longevity of adults, very little is known about the health habits of disadvantaged school-age children. This study set out to evaluate eating breakfast among adolescent girls and its relationship with body mass index, weight and nutrient intake.

  Methods : This descriptive cross-sectional study was done on 611 adolescent primary and secondary school girls (10-14 years old) in Ardabil. Anthropometric studies (height, weight, and MAC) and nutritional status (24 hour recall and food frequency) were done, and the students were asked about eating breakfast and other snacks. The collected data were analyzed using SPSS ver. 9 and Food Processor.

  Results : About 16.85% of girls had come to school without eating breakfast. BMI and body weight of these students were significantly more than those of girls who ate breakfast (P<0.05). On the other hand snack intake among the girls who did not use to eat breakfast was more than that among breakfast eaters (P<0.05). The amount of calorie, protein, thiamin, niacin, calcium and iron intake in breakfast-eating girls was more than those among non-eaters (P<0.05). The amount of folacin, riboflavin, calcium and zinc intake in non-eaters was less than recommended dietary allowance of WHO. The result of food frequency showed that the consumption of food such as protein different types of bread, potato, and legume among breakfast eaters was more than their consumption among non-eaters.

  Conclusions : This study indicated that eating breakfast can provide adequate calorie and nutrients but its omission can not only lead to lower calorie and nutrients intake but also have an unfavorable effect on food habit and weight of the students.

  Background & Objectives: Urinary stone disease is one of the common urinary tract complications that can lead to renal failure. It occurs usually in middle-aged and older men The aim of this study was to determine the association between types of urinary stones and risk factors for urinary stone formation in patients referred to Ardabil therapeutic centers.

  Methods : In this descriptive cross-sectional study, 150 patients with urinary stone were followed from March 2008 to July 2009 in therapeutic centers of Ardabil.

  Data were collected by a questionnaire include demographic factors such as age, gender, body mass index (BMI), Job and Habitation place. Data were analyzed by chi-square test and ANOVA in SPSS 16 software. The level of significance was p<0.05.

  Results: 116 of patients (77.3%) had calcium oxalate stone, 15 of patients (10%) had phosphate calcium stone, 10 of patients (6.7%) had acid uric and 9 of patients (6%) had phosphate ammonium stone. The mean age of patients was 41.90 + 14.41 years (48% of patients were 30-50 years old) and the mean body mass index (BMI) was 25.81+3.66. 91 of patients (60.66%) were male and 59 (39.4%) of them were female. There was no significant difference between types of urinary stones and factors including BMI the job of patient, (p=0.252), habitation place (p=0.173), history of previous illness (p=0.207) and history of drug use (p=0.247).

  Conclusion: The most common type of urinary stones was calcium oxalate (77.3%) in both men and women however ammonium phosphate (6%) is much less common.

  Background & Objectives: Colorectal cancer is considered as the third prevalent malignancy worldwide. Investigation of information on cancers in Iran during 1985-1996 showed an increase in the incidence and prevalence of colorectal cancer. Its rank in Iran has increased from 9 to 5th during 10 years. It was reported as high prevalent cancer in Iranian people aged less than 40 years among Asian countries.

  Methods: In this cases-control study patients with a pathologic report of colorectal cancer were recruited among those cases registered in Ardabil Cancer Registry. Control group were selected from neighbors, frequency matched for age and gender. Subjects were interviewed using a questionnaire consisting information on age, gender, smoking, drugs and alcohol consuming, diet, family history of cancer and serum IgM and IgG level for H. pylori. Data were analyzed using SPSS v16.

  Results: In the current study, 43 persons (53.8%) were male and 37 (46.2%) were female. In the case group, 10 persons (12.5%) were under 40, 34 cases (42.5%) in age group of 41- 60 and 36 persons (45%) were more than 61 years. In the control group 12 persons (15%) were under 40, 36 persons (45.5%) in age group of 41-60 and 40 persons (68%) were more than 61 years. In the control group 3 cases had BMI less than 19, 36 cases (45%) between 19-24.9, 31 cases (38.8%) between 25-29.9 and 10 cases (12.5%) were more than 30, whereas this variable was 2.5, 32.5, 46.2 and 18.8% respectively in the case group.

  Positive history of smoking found to increase the risk of cancer around 1.8 times (OR= 1.78 CI: 0.91- 5.85). However, significant difference was not observed between two groups regarding alcoholic beverage consumption (p=0.385) . There were significant differences between two groups in terms of vegetables and carbohydrates intake. Difference was also significant between two groups regarding positive level of IgG. Among studied persons, 19 and 13 patients in case and control group had positive IgM respectively.

  Conclusion: Our finding showed an increased risk colorectal cancer in those consuming low vegetable and fruits and high carbohydrate consuming, having smoking history, positive family history of cancer and serum IgG level.
