ABSTRACT
Background: having appropriate nutrition can affect the quality and quantity of adolescent students' growth; therefore this study was conducted to assess the nutritional status and its relationship to the educational achievement among adolescent students.
Methods: This cross sectional study was carried out on 800 adolescent students who were in a range age of 14-18 years in Sabzevar, Iran. Multi-stage random sampling was used .in order to this, after receiving permission from Sabzevar Education Office, subjects were randomly selected from the first to fourth grade girlish and boyish high schools of city and then, demographic checklist, academic information and food frequency questionnaire were completed by students. Also, their weight and height were measured using standard methods. The quantity of food mentioned in food frequency questionnaire was converted to gram through the domestic index guideline. Next, every food was coded biased on Nutritionist IV instructions and analysis was performed via descriptive statistics, frequency and the correlation coefficient and one sample t-test by means of SPSS 16 software in a significant level of P<0.05.
Results: The mean BMI of female and male students were 20. 3 +/- 2.7 and 19.5 +/- 3.2 kg/m2, respectively. Dietary assessment showed amount of Energy, vitamins A, C, D, folic acid, calcium, iron and zinc intake were less than DRI [P <0.05]. Also, among all of the nutrients there was only observed a significant correlation between iron intake and total average score and specific average scores in female students [P <0.05].
Conclusion: The findings of this study indicated a lower intake of some nutrients among sabzevarian high school students than the DRI.
ABSTRACT
Anorexia, limitation in the intake of some nutrients, loss of nutrients during dialysis, and extensive inflammation are important causes of malnutrition in hemodialysis patients. For this reason, this study reviews the status of macro- and micronutrient intake in these patients as compared to Dietary Reference Intake [DRI] values. This cross-sectional study was performed on 75 hemodialysis patients referred to the dialysis department of Vasei Hospital, Sabzevar, Iran. After measuring height and body weight, nutrient intake of each patient was determined using 24-hour food recall method for two consecutive days [one day on and one day off dialysis] and the frequency of meals was recorded. Nutrient intake of each individual was determined using Nutritionist IV software. Data were analyzed by descriptive statistics and one-sample t-test at the significance level p < 0.05. The mean BMI of patients in this study was 20.04 +/- 3.38 kg/m2. The mean energy intake was 1767.98 +/- 373.85 and 1816.76 +/- 433.16 kcal in women and men, respectively, and the mean protein intake was 67.92 +/- 21.11 and 69.30 +/- 21.38 g per day in men and women, respectively. Also, in this study, the intake of all nutrients, except vitamins B1, B3, B12, and iron, was less than the recommended standard in hemodialysis patients [p < 0.05]. Based on the findings of this study, the intake of most water- and fat-soluble vitamins and minerals was less than the recommended standard in hemodialysis patients
ABSTRACT
Background and Purpose: There is evidence on the antiobesity effects of dietary calcium. Most employees have low physical activity and due to many rounds of work, their nutritional intake is affected, and around one-fifth of them suffer from overweight. The present study was conducted to investigate the correlation of dietary calcium and anthropometric indices in the staff of Vasei Hospital in Sabzevar, Iran
Methods and Materials: The cross sectional descriptive study was conducted on 300 employees at Vasei Hospital in Sabzevar, Iran. Their weight, height, hip and arm circumference were measured by standardized procedures to take a record in data collection forms. A 24-hour recall form was given for two successive days to each participant, and a food frequency form was completed for the annual nutritional pattern of each participant. The food intake by grams was given into the Food Processor 3 software. Then, each participant's data on nutrients and their anthropometric readings were fed into SPSS 14 for analyzing by independent t-test, Person correlation coefficient, One-way and Two-way ANOVA
Results: In this study, 77.9% of the participants had normal weight and 22.1% were overweight. Mean calcium intake was 1843.57 +/- 1383 and 1023.99 +/- +/-703.71 mg/day in men and women, respectively. No correlation was observed between calcium, BMI [p=o.52] and body weight [p=0.22]. However, there was significant negative correlation between dietary calcium and hip [p=0.01] and arm circumference [p=0.04] in men
Conclusion: The results showed that there is no significant correlation between dietary calcium, BMI and body weight
