    The effect of various nitrogen fertilizers on zinc (Zn) availability in non calcic brown forest soils
    (2004) Adiloglu A.; Adiloglu S.; Gonulsuz E.; Oner N.
    In this article the effect of different nitrogen fertilizer application on the availability of zinc (Zn) content in non calcic brown forest soil was investigated. For this purpose increasing rates of NH 4 Cl, (NH 4 ) 2 S0 4 ; NH 4 N0 3 and Ca(N0 3 ) 2 .4H 2 0 fertilizers were applied for having different physical and chemical properties in two soil samples. An incubation experiment was carried out over 4 months. The available Zn content of the soils was determined each month. According to the results the highest available Zn content of the soils was obtained from NH 4 Cl applied to the soils followed by (NH 4 ) 2 S0 4 ; NH 4 N0 3 and Ca(N0 3 ) 2 .4H 2 0 application to soil. At the end of the experiment the average available Zn content of non calcic brown forest soils for NH 4 Cl, (NH 4 ) 2 S0 4 ; NH 4 N0 3 and Ca(N0 3 ) 2 .4H 2 0 fertilizers are 0.93, 0.91, 0.88 and 0.77 mg kg ?1 , respectively. © 2004 Taylor & Francis Group, LLC.

    Obesity Risk Factors in Turkish Children
    (2009) Garipagaoglu M.; Budak N.; Süt N.; Akdikmen Ö.; Oner N.; Bundak R.
    On the basis of the knowledge that the prevalence of obesity in children has increased steadily in recent years, this study aimed to assess the association between obesity and certain risk factors in a group of 6- to 14-year-old children living in Istanbul. The study was carried out at the Istanbul University School of Medicine Hospital. Data were collected from 592 children aged between 6 and 14 years who were examined in general pediatrics clinics. Weight and height measurements were performed on the children and their parents. The children were classified as obese and nonobese in accordance with the body mass index reference values for Turkish children. Energy intake of children was estimated with a 3-day food consumption recording form. A structured questionnaire was used to collect the information from the parents on possible risk factors causing obesity. The physical activity state of the children was assessed. A logistic regression model was developed to examine the relationships between obesity and possible risk factors. Almost 32% (n = 184) and 69% (n = 408) of children were assessed as obese and nonobese, respectively. Although there was no difference in daily energy intakes of obese and nonobese children, 13.6% of obese and 40.9% of nonobese children were reported to do physical activity regularly. Obesity was strongly associated with parental obesity. Furthermore, energy intake; having regular physical activity; presence of obesity in the mother, the father, and the mother's family; and having a mother working out of home were also significantly associated with obesity. Creating awareness in mothers on the importance of a healthy nutrition and encouraging families to participate in physical activities are important points in the prevention of childhood obesity. © 2009 Elsevier Inc.
