Abstract
The effects of taking snacks on the learning ability and educational achievement of elementary school children in district 18 of Tehran educational organization were examined in the school year 1997-98. Other factors such as grade, nutritional status, breakfast eating habits and snack eating habits in the school were also studied. For this purpose 236 boys were selected by random sampling in 4 different schools. The children were randomly assigned to a group, with a low calorie snack (119 subjects), and a low-calorie control group (117 subjects), and then given 3 cognitive functions tests. The test were repeated after 4 months. The data were collected by questionnaires and included family socio-economic conditions, nutritional status and dietary habit of the children. Also, the grades of the major courses and scores of cognitive tests were collected, and the effects of treatment on the mean grades and scores differences were determined by T-test and analysis of variance (ANOVA). Our findings are presented as follow: The experimental and control groups were similar in the initial assessment. 7.1% of the students were stunted based on height-for-age classification (NCHS). The intervention led to an increase in tests scores, but the increase was only significant in the case of the short-term memory test (P<0.03). The findings of the study showed that the intervention was effective on short-term memory and since short-term memory function in memorization process and retrieval of subjects form long-term memory and congenitive functions, we can conclude that the food intervention with an energy lower than 10% of recommended dietary needs increases learning ability level of the subjects. Stunting and the habit of eating breakfast were related to educational performance of students. Therefore implementation of such programs in the community, such as food intervention and nutritional education may be effective.

Abstract
The purpose of this study was to assess the prevalence of malnutrition and related factors that may affect the nutritional status of 0 to 59 month old children in the rural areas covered by the Birjand district health network. A total of 626 children were selected by random sampling. Data were collected using a questionnaires and face-to-face interviews with the mothers and by measuring weight and height of te children. The nutritional status of the children determination was based on the z-score (cut-off poing under-2Sd from median reference population). Based on the z-score and under 2-standard deviation from median of NCHS in rural areas of Birjand, 18.5%, 40.1% and 3% of children were suffering from past-and-present, and present, malnutrition, respectively. Therefore the highest prevalence of malnutrition was related to the past-malnutrition and the stunting was the main problem. The chi2 test showed a statistically significant relationship between the children's past malnutrition and fathers litarcy (P<0.001), also between the children's past and present malnutrition and mother's literacy (P<0.021) and past malnutrition (P<0.001). There was also significant relationship between, father's main occupation, per-capita income (P<0.0001, P<0.025 respectively) and children's past malnutrition in the cases under study. In this research, relationship between sex and prevalence of malnutrition in both peresent-past and past malnutrition was meaningful, (P<0.024, P<0.017 respectively). This study did not show a significant relationship between nutritional independent variables and nutritional status of the children.

Abstract
Background: The effects of population aging are becoming apparent throughout the world. Diseases, such as cardio-vascular disease (CVD) and diabetes, are among the most important factors affecting morbidity and mortality, especially in the elderly. These diseases not only result in huge economic costs for treatment and care, but also results in hardship and time lost for relatives of the afflicted individuals. The association between nutritional status and disease is well known. In the present study, the effects of both under-nutrition and over-nutrition on the prevalence of disease are monitored in an urban Iranian elderly population. Thus far, no similar study has been performed in the Iran.
Methods: This cross-sectional study was conducted in Isfahan, Iran, during late 2003 on 1694 elderly people (731 males, 963 females), aged 60 years and older. Subjects were randomly chosen from all urban elderly people during a door-to-door and weight and height survey. They were selected using a cluster sampling method, each containing 30 clusters. From each cluster, 58 elderly were selected at random. Using each subjects body mass index (BMI), the nutritional status was categorized as overweight (BMI greater than 25), underweight (BMI less than 19) and normal (having a BMI equal to or more than 19 and equal to or less than 25). Any illnesses known to each subject were also recorded.
Results: Results showed that 4.7% of the subjects were underweight and 61.2% overweight. Women were more likely to be overweight and long periods of watching television increased the risk of overweight in all subjects. Being overweight was associated with diabetes and coronary vascular diseases, and lean people were less likely to suffer from such diseases.
Conclusion: This study indicates a high prevalence of overweight among the Iranian elderly population, indicating the need for improvement in nutritional status in order to reduce the prevalence of diabetes and CVD.
