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
Background: Breast cancer is the most common cancer in women and its treatment includes various surgeries. Breast-Q is a new patient-reported outcome instrument for breast surgery and it should be validated appropriately for clinical research. This study aimed to develop the Persian version of the Breast-Q and validate the reconstruction module to evaluate the quality of life and satisfaction of Iranian women with a previous history of breast reconstruction.
Methods: This study was descriptive and analytical cross-sectional. The study population consisted of women with a previous history of breast cancer and various breast surgeries referred to the outpatient clinic of Cancer Institute, Imam Khomeini Hospital from September 2017 to October 2019, using convenience sampling. After obtaining permission from the MAPI institute and translating all questionnaires into Persian, the validity, and reliability of the breast reconstruction module were evaluated. To confirm face validity, a questionnaire was given to patients to judge each item. To confirm the content validity of the questionnaire, two qualitative and quantitative methods were used. Content validity ratio (CVR) was calculated based on the expert opinion (Lawshe formula). Waltz & Bausell’s method was used to examine the content validity index (CVI). Finally, a new version of the questionnaire was assessed in 20 women who had undergone TRAM flap breast reconstruction at least 6 months ago.
Results: After translation of the questionnaire into Persian, and face and content validation process, the 116 items of the first questionnaire converted to 72 with an acceptable impact score greater than 1.5 and CVR and CVI. The internal validity of the breast reconstruction module was approved by Cronbach's alpha value of 0.94.
Conclusion: Considering the limitation of the specific questionnaires for various breast surgery procedures, the Breast-Q questionnaire can be an efficient tool for the evaluation of the quality of life and satisfaction in patients. Since the translation of the questionnaire has become valid and reliable, it can be used for future research by other researchers. |
