Potential hepato-protective effect of Salvia hispanica (chia) and Chenopodium quinoa (quinoa) in diabetic male albino rats

Chia and quinoa seeds are novel sources of bioactive compounds that may improve lipid profile, blood glucose homeostasis, and body weight in diabetic rats. This work aims to study the effect of different percentages of chia and quinoa consumption, alone or in a mixture, compared to Metformin drug on regulating lipid profile, blood glucose level, and weight of male diabetic rats. The consumption of quinoa and chia seeds showed a significant decline in fasting blood glucose (FBG), fasting insulin level, Hemoglobin A1C (HbA1c), and Homeostatic Model Assessment for Insulin (HOMA-IR), while the best results were obtained with Metformin and chia seeds. A decrease in mean body weight, triglycerides, total cholesterol, low density lipoprotein (LDL-C), and very low-density lipoprotein (VLDL-C), and an increase in high density lipoprotein (HDL-C) occurred, which was significant when consuming chia and quinoa seeds rather than treatment with metformin. Chia and quinoa seeds could improve blood glucose homeostasis and lipid profile in diabetic rats. These research findings could promote the daily consumption of quinoa and chia as great functional foods that could improve blood glucose homeostasis and lipid profile

Development and validation of an Arabic questionnaire to assess psychosocial determinants of eating behavior among adolescents: a cross-sectional study

Background: There is a scarcity of studies that evaluate the psychosocial determinants of eating behavior among adolescents in the Eastern Mediterranean region. The availability of such data is limited by the lack of valid culturally appropriate tools. The current study aims to develop and validate an Arabic questionnaire that measures psychosocial determinants of eating behavior among adolescents. Methods: A cross-sectional study was carried out to validate a five-scale questionnaire developed to measure nutrition-related knowledge, attitude, practices, and self-efficacy and social norms. Content validity was assessed by Lawshe\u2019s method, factor analysis was used to assess construct validity, and Cronbach\u2019s \u3b1 was used to test internal consistency. Temporal stability was assessed by test\u2013retest reliability. A random sample of public and private school students participated in the validation study. Results: All the five scales demonstrated excellent content validity (content validity ratio, CVR 650.778). Factor analysis revealed several dimensions for each scale. Cronbach\u2019s \u3b1 for the identified dimensions or subscales ranged between 0.495 and 0.809 indicating acceptable internal consistency. Cronbach\u2019s \u3b1 for the total scales ranged between 0.759 and 0.836. Test\u2013retest analysis revealed good temporal stability (intraclass correlation, ICC >0.7). Conclusions: A psychometrically valid tool to measure psychosocial determinants of eating behavior was developed. This tool can serve as a potential instrument for pretest and impact evaluation of ongoing nutrition education interventions and curricula. Based on results obtained from this tool, efficacious modifications can be instilled for nutrition policies and interventions

The current study aims to develop and validate an Arabic questionnaire that measures psychosocial determinants of eating behavior among adolescents. Methods A cross-sectional study was carried out to validate a five-scale questionnaire developed to measure nutrition-related knowledge, attitude, practices, and self-efficacy and social norms. Content validity was assessed by Lawshe’s method, factor analysis was used to assess construct validity, and Cronbach’s α was used to test internal consistency. Temporal stability was assessed by test–retest reliability. A random sample of public and private school students participated in the validation study. Results All the five scales demonstrated excellent content validity (content validity ratio, CVR ≥0.778). Factor analysis revealed several dimensions for each scale. Cronbach’s α for the identified dimensions or subscales ranged between 0.495 and 0.809 indicating acceptable internal consistency. Cronbach’s α for the total scales ranged between 0.759 and 0.836.

Transitions to Adulthood: A National Survey of Adolescents in Egypt [1st edition, Arabic]

Egypt holds a unique place among developing countries due to its longstanding commitment to gather information on the numbers and well-being of its population. But until now, there has never been a systematic effort to gather data on the group of young Egyptians poised between childhood and adulthood—its adolescents. Today, Egypt has the largest cohort of adolescents in its history, more than 13 million boys and girls between the ages of 10 and 19 according to its 1996 census. Their experiences during the transition to adulthood will profoundly affect how the nation makes its transition into the next century. This research report contains the early findings of a nationally representative survey of 9,000 adolescents aged 10-19 and their parents, conducted in 1997, and aims to provide a comprehensive picture of the contemporary situation of Egypt’s young people. The report attempts to achieve a fuller understanding of the major developmental “tasks” each adolescent undertakes as he or she moves toward the roles and responsibilities of adulthood, as well as household perspectives on the services and institutions available in Egypt to support those transitions
