Background: Continually rising prevalence of obesity and overweight in children and adolescents is a major public health concern. This is due to its various and serious health hazards on one side and its preventable nature on the other side. This study aims at identification of prevalence of overweight and obesity and its risk factors among children between 6 - 14 years of age in Sohag, Egypt. Method: A cross sectional study was conducted on 711 school children between 6 - 14 years in four months’ period from February to May 2016. Weight and height of the studied children were measured to calculate BMI, which was compared with standard Egyptian growth charts for determining overweight and obesity. Then a questionnaire containing data about socio demographic, parental obesity, early life and dietary risk factors was completed by the children’s parents. Result: Out of 711 studied children, 117 (16.5%) were overweight and 104 (14.6%) were obese. Residing in urban area, having an obese parent or both of them, low level of maternal education, being on formula feeding during early life and lack of fresh vegetables and fruits in diets were significant risk factors for overweight and obesity in the studied children (P value < 0.05). Conclusion: Improperly educated mothers together with sedentary life style manifested in obesity among the parents and lack of sport practice among children constituted the majors risk factors for childhood obesity. This emphasizes the need for increased health awareness of the community about the importance of proper nutrition and physical activity.

A pressure dependent Schrodinger equation is used to find the conditions that lead to superconductivity. When no pressure is exerted, the superconductor resistance vanishes beyond a critical temperature related to the repulsive force potential of the electron gass, where one assuming the electron total energy to be thermal, where applying mechanical pressure destroys Sc when it exceeds a certain critical value. However when the electron total energy is an assumed to be that of the free electron model and that the pressure is thermal and mechanical, the situation is different. The quantum expression for resistance shows that the increase of mechanical pressure increases the critical temperature. Such phenomenon is observed in high temperature cupper group.
