Abstract
The start of this survey, 588 students (294 in either area) were selected randomly but the ultimate size of the sample was increased to 905, allowing for a 35% omission rate. Anthropometric measurements and stool examinations were performed. Questionnaires dealing with socioeconomic status were completed through interviews with mothers. We also carried out blood tests on a subsample of 180 individuals (1/5 of the the original sample).The results of the study were as follows:In Area 1:4.3% and 15% of the subjects showed evidence of anemia and parasites, respectively.Th mean hemoglobin and hematocrit concentrations were 13.46 g/dland40%.Anthropometric assessment revealed rates of 8.6% and 1.3% for severe wasting and obesity, and 11.9% for severe stunting. Gauging the weight-for-age index on standard growth charts, 13.1% of the subjects had severe wasting and 14.4% suffered from severe stunting and based on BMI, 21.3% were severely malnourished.ln Area 2:5.8% and 13% of the subjects suffered from anemia and parasites, respectively.Mean hemoglobin and hematocrit concentrations were 13.05 g/dl and 37.8%.Anthropometric assessment showed that 9% of the subjects had severe wasting, and 1.8% were obese. 11.7% showed severe stunting. On standard growth charts, 12.4% had severe wasting and 15.3% were severely stunted. Judging by the Body Mass Index, 21.6%) of the subject had severe malnutrition.The mean weight, height and BMI in both areas were substandard and the mean weight in Area 1 was lower than in Area 2. Statistical Associations:In Area 1: the following variables showed statistically significant relationships: History of parasite infection in the last year with child's weight for age. Mother's age and history of maternal parasite infection in the fast year with child's height for age.Parasites infection in the last year with BMI.In Area 2: statistically significant relationships were found:Between mother's literacy / mother's job /family income and child's weight for age.Between family income / percentage of income spent on food/ current parasite infection and height for age.Between diseases affecting food intake and BMI.

Abstract
Many studies indicate that the nutritional knowledge and practice of adolescent girls are inadequate. Few surveys were performanced about effect of nutrition education on knowledge, attitude and practice in this vulnerable group. The purpose of this study was to compare the effect of two nutrition education methods (guidebook and group discussion) on the nutritional knowledge, attitude and practice of first-grade guidance school girl students in Tehran ’s 8th district, in 2003.A total of 300 students were selected from 11 guidance schools by simple random sampling and divided into three 100-student groups: 1-guide-book, 2-group discussion, and 3-control. Data on the nutritional knowledge, attitude and practice were collected using pretest and posttest questionnaires. The students in group1 were given the guide-book and required to study it at home, while group 2 students were told to discuss among themselves the contents of the guide-book. The control group were given nothing to study or to do. The pre-test showed that the mean scores of nutrition knowledge (K), attitude (A) and practice (P) were not statistically different among the 3 groups. The scores for the 3 variables increased in the guide-book and discussion groups significantly at the end of the study period (in all cases, p<0.001), while the inter-group comparisons also showed that the K and A scores were statistically different among the 3 groups the P, however, was not different among them. Conclusion: Both methods (guide-book and group discussion)increased the level of nutritional knowledge and attitude as compared to (a) – the control group,and (b) – the initial values. Also both methods increased the level of nutritional practice as compared to (b) – the initial values. The group discussion method was more effective than the guide-book method in the promotion of the nutritional knowledge of the students.

Abstract
Background and Aim: Breast carcinoma is the most common type of cancer in women. It has been estimated that 8-9 percent of all women will develop breast cancer during their lifespan. According to The Iranian Ministry of Health and Medical Education, the incidence of breast cancer in Iran has risen between 1984 and 1988 and the current mortality rate from this kind of cancer ranks fifth in the country.
Materials and Methods: In this case-control study, 110 patients with breast cancer (ages 20-60 yrs) were compared with a similar number of age- and sex-matched women hospitalized for other reasons. Cases were women with histologically confirmed in situ or invasive breast cancer diagnosed no more than 1 year before the interview and with no previous diagnosis of cancer at other sites. Controls were drawn from either patient relatives or from women with no history of cancer admitted to Imam Hospital for acute, non-neoplastic, non-gynecologic conditions unrelated to hormonal or digestive tract disease or to long-term diet modifications. We calculated odds ratios and performed Mantel-Haenzel as well as logistic regression tests to control for potential confounding factors.
Results: Odds ratios [with 95% confidence intervals] for total fat, saturated fatty acids, monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA) and cholesterol were 1.97 [1.062-3.67], 1.19 [0.64-2.14], 2.2 [1.17-4.13], 4.11 [2.2-7.65] and 0.45 [0.25-0.83], respectively. After adjusting for energy, macronutrients, weight, age at first full-term pregnancy and the socioeconomic status, it emerged that the intake of PUFA (OR=6.38 and 95%CI: 1.95-20.83) had a positive association with breast cancer while cholesterol (OR=0.22 and 95%CI: 0.09-0.55) showed a negative relationship, though the latter finding only applies to menopaused women.
Conclusion: Undoubtedly, dietary factors involved in the etiology of breast cancer take many years to cause any pathologic changes in any organ. Nonetheless, one-year frequency of lipid intake is a good measure of individual's dietary habit throughout his/her adult life. Based on this, the present study suggests that increased PUFA intake- probably due to its high pro-oxidant potential- can be considered as a key factor in the rising incidence of breast cancer in Iran.

Abstract
Background and Aim: Adolescence is the transition period between childhood and adulthood, a period in life that begins at puberty. It is one of the fastest growth periods in a person's life. During this time, physical changes affect the body's nutritional needs, while changes in one's lifestyle may affect eating habits and food choices. Nutritional health during adolescence is important for supporting the growing body and for preventing future health problems. In Iran, the prevalence of anemia, obesity, and other chronic nutritional diseases has increased in recent years due to undesirable eating habits. This survey was conducted to determine consumption of the four major food groups (vegetables, fruits, milk products, and meat) among a group of high school students in Zanjan Province, Iran.
Methods and Materials: A descriptive, cross-sectional study was carried out on 1500 students, selected by random cluster sampling, in Zanjan high schools, Iran in 2005. The daily intakes of the 4 food groups during the previous week were determined using a food frequency questionnaire. The potential determinants of the pattern of food consumption were also determined.
Results: The proportions of the students not having consumed fruits, vegetables, and meat during the weak were 16%, 6.8%, and 10%, respectively. More than 95% of the students said that they had consumed milk/milk products at least once a day. Only 8.7% consumed fruits and 27% consumed vegetables 3 times or more daily.
Conclusion: The consumption of the 4 food groups of large proportions of Zanjan Province adolescents is below the current recommendations. Health and nutrition educational programs would be a valuable tool to correct erroneous food habits of the adolescents leading to improvements in their nutritional status.

Abstract
Background and Aim: Today cardiovascular diseases are the main cause of disability and mortality in many countries. This study was performed to determine the effect of health education based on the Health Belief Model on the knowledge, attitude and practice of housewives in Isfahan, Iran regarding improving their nutritional behavior for preventing heart disease.
Materials and Methods: This was a quasi-experimental intervention, including 68 Isfahani housewives randomly divided into an experimental (n=34) and a control (n=34) group. Data were collected using a standard health belief model (HBM) and a food-frequency (FFQ) questionnaire. The experimental group attended, after a pre-test, 6 weekly education sessions. The HBM questionnaire was completed 3 times (before and immediately, and 2 months, after education), while the FFQ questionnaire was completed twice (before and 2 months after education) by the housewives. The data were analyzed using SPSS16 software, the statistical tests being t-test, and repeated measure ANOVA.
Results: The two groups were not significantly different with regard to demographic variables. Similarly, before the intervention they were statistically similar with respect to the scores of the HBM components (P>0.05). After the intervention, significant differences appeared between the experimental and the control groups with regard to all the components (knowledge, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, perceived efficacy, and performance in all cases, P<0.001)
Conclusion: Based on the findings, it can be concluded that the intervention had a positive impact on the feeding pattern of the women and was effective in increasing or improving their knowledge, attitude and practice.

Abstract
Background and Aim: To examine the association of diet and the risk of esophageal squamous cell carcinoma (SCC) in Kurdistan province.
Materials and Methods: This was a case-control study including 47 patients with esophageal SCC and 96 healthy controls. Dietary intake was assessed using a valid semi-quantitative food frequency questionnaire. Logistic regression analysis was run to estimate odds ratios and 95% confidence intervals.
Results: The controls had a significantly higher mean body mass index (25.3 vs. 20.4) and a higher level of education than the case group, while the latter had significantly higher records of tobacco consumption and symptomatic gastresophageal reflux. An independent protective effect was observed for the highest tertile of total fruit consumption (OR: 0.13, CI: 0.04-0.45, p-value=0.001). Within the fruits group, a significant inverse association was observed for bananas, kiwis and oranges (P for trends: 0.03, 0.02 and 0.01, respectively). The effect of total vegetable intake on esophageal SCC was not significant (OR: 0.66, CI: 0.23-1.87), although a reduction in risk was observed in the highest tertile of intake. With regard to other food groups we did not find a statistically significant association.
Conclusion: The results of the present study suggest an inverse association only between fruit consumption and esophageal SCC.

Abstract
Background an Aim: Aging trend especially in developing country is increasing. This study aimed to assess the nutritional status of the elderly and its associated factors in Gorgan .
Materials and Methods: This is a cross sectional study that two-stage cluster sampling method was used for considering participant. The data were collected using Mini Nutritional Assessment and anthropometric questionnaire which was referred to the elderly inhabitant in urban area. 541 elder were interviewed and data were analyzed by chi square, independent T test and one way ANOVA tests.
Results : The prevalence of malnutrition was %4/8 and nearly %44/7 of the elderly were at the risk of malnutrition. %51/9 of the elderly were on a special diet due to a disease or specific condition. Malnutrition frequency and the risk of it were higher in woman than men and the difference between sexes was statistically significant. BMI, mid arm circumference and calf circumference measures in elderly with malnutrition were less than elderly with good nutrition, and the difference was statistically significant
Conclusion: The risk of malnutrition in elderly who exposed to socio-economic, mental and also dental difficulties, living alone and female old age was higher than others groups. The implementation of supportive and nutritional programs is more important in this group.

Abstract
Background and Aim: The role of nutritional quality of the diet in the development and progression of multiple sclerosis (MS) is not yet well understood. The aim of the present study was to determine the association between index of nutritional quality (INQ) and MS.
Materials and Methods: In this case-control study, 70 patients with a definitive diagnosis of MS in the preceding year and 140 frequency-matched hospital controls were selected from among 20-50 year-old patients referred to Sina and Lolagar hospitals in Tehran. The subjects’ dietary intakes were assessed using a valid and reliable semi-quantitative food frequency questionnaire. INQs for all the nutrients were then calculated for every participant, and logistic regression analysis was used to calculate the odds ratios for having MS in relation to every nutrient’s INQ.
Results: After adjusting for potential confounders, it was seen that subjects who had higher INQs for alpha-linolenic acid, vitamins A, D, K, B1, B2, B5, B6, folate, B12, and C, and minerals calcium, phosphorus, zinc, and potassium were less likely (p<0.05) to have MS as compared to subjects with lower INQs for these nutrients.
Conclusion: The findings of the present study show inverse associations between the INQ of many nutrients and risk of having MS. Therefore, it seems that overall improvement of the nutritional quality of the diet might be an appropriate approach for prevention of this disease.

Abstract
Background and Aim: Nutritional knowledge acquired by young girls as would-be mothers will play an important role in children’s and family health protection and promotion in the future. The purpose of this study was to determine the effects of an educational program based on the BASNEF model on the nutritional behavior among guidance school first-grade female-students.
Materials and Method: This was an interventional study carried out in the form of a clinical trial including 160 female-pupils divided into two groups ─ a case and a control group ─ randomly selected by two-stage sampling, namely, classification and cluster sampling. The data gathering tool was a questionnaire. Education about healthy nutrition was imparted to the case group in 4 60-minute sessions in the form of lectures, group discussions, and question-answer in addition, pamphlets were distributed among the subjects. Data were collected and analyzed using the SPSS-18 software, the statistical tests being Chi-square, fisher , independent and paired t-tests.
Results: The data showed that the mean scores of knowledge and BASNEF model components as regards nutritional behavior increased after the intervention in the case, they being higher significantly in the case group as compared to the controls. The most important subjective norms after the intervention were the pupils’ parents .
Conclusions : The findings indicate that a 3-month educational intervention based on the BASNEF model can bring about desirable changes in some of the undesirable nutritional behaviors in guidance school pupils, and that designing and implementing interventions of this kind, with the support of health and school authorities, is quite feasible.

Abstract
Background and Aim: The present study aimed to determine the stages of changes and cognitive and behavioral processes (Transtheorical model) in the use of nutrients in overweight middle-aged women.
Materials and Methods: The present study was a descriptive-analytic. The research sample consisted of 281 middle-aged women with overweight referring to comprehensive health centers in Isfahan. Personal characteristics, stage of change and behavior and cognitive behavioral processes, and FFQ questionnaire (168-item) were completed by Questioning, and then the information entered the N4 and SPSS 18 software, and information was analyzed using descriptive and analytical tests.
Results: 57.7% of the people were inactive (pre-thinking, thinking, preparation) and 42.3% of them were in active phase. There was a significant difference between the different stages of change and the use of behavior change processes (p=0.001) And Benfrown's test shows the increasing use of cognitive and behavioral processes during the stage of change in use of nutrients (p<0.001).
Conclusion: The difference in the mean of changes processes during the stage of change show the impact of these processes on the nutritional individual's behavior, which is recommended to use stage of change and behavioral change processes for education nutrition behavioral.

Abstract
Background and Aim: Patient education is an essential component of diabetes control, and increasing the health knowledge of diabetic patients based on suitable educational theories is crucial. This study aimed to determine the effect of educational intervention using the Transtheoretical Model (TTM) on improving the nutritional habits among patients with type-2 diabetes mellitus in Maragheh city, Iran during 2017-2018.
Materials and Methods: This study was a randomized controlled trial conducted on 136 diabetic patients under coverage of Maragheh health centers, Maragheh city, Iran, randomly divided into two groups of intervention and control (68 participants in each group). The data collection tool was a three-part questionnaire with questions/items related to demographic characteristics and nutritional habits, as well as constructs of TTM and HbA1c based on the TTM. The educational program included four weekly sessions of 45-60 minutes each. The data were analyzed using the SPSS16 software, the statistical tests being descriptive and inferential tests such as ANCOVA; the significance level was set as a p-value < 0.05.
Results: Before the intervention, the comparison and control groups did not differ significantly as regards demographic variables, HbA1c, TTM constructs and nutritional habits (p<0.05). After the educational intervention, the mean scores of nutritional habits, constructs of TTM and HbA1c were statistically significant in patients with type 2 diabetes (p <0.01).
Conclusion: The study results reveal that the application of transtheorical model can improve the nutritional habits of diabetic patients.

Abstract
Background and Aim: Physical activity and nutrition are important topics in adolescent health. This study aimed to determine the predictors of nutritional knowledge, behaviors, and physical activity in fifth-grade elementary school female students
Materials and Methods: This cross-sectional descriptive-analytical study was performed on 480 female students in the fifth grade of the elementary school in Gods city in 2020-2021 by cluster random sampling. Data were collected using a researcher-made questionnaire two-part questionnaire of contextual questions and questions about knowledge, nutritional and physical activity, virtual in the Shad messenger. The content validity ratio and content validity index was used to determine validity, and the intra-cluster correlation index to determine the reliability, of the questionnaire. In data analysis, descriptive statistical tests, Pearson
correlation coefficient, and multiple regression analysis were performed using SPSS 27.
Results: The results of multiple regression analysis showed the effect of nutritional knowledge variables on nutritional behavior (p <0.001, β = 0.159) and physical activity knowledge on nutritional behavior (p = 0.008, β = 0.120) if the Physical activity knowledge variable was not effective on physical activity behavior and also nutritional knowledge variable had no effect on physical activity behavior.
Conclusion: Increasing knowledge of nutrition and physical activity improves students' nutritional behavior, but this increase in knowledge does not affect physical activity behavior. The sedentary lifestyle and the presence of the Covid-19 pandemic appear to have significantly reduced physical activity. By increasing knowledge, nutritional behavior and physical activity can be improved to some extent
