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.

Background and Purpose. Because the blood-brain barrier serves as a pharmacological barrier, malignant cells can remain in the central nervous system (CNS) despite systemic chemotherapy. Consequently, CNS-directed treatment is an essential part of therapy for Non-Hodgkin lymphoma (NHL). We aimed in this analysis to determine the neurocognitive effects of CNS-directed chemotherapy in children with NHL. Methods. In a cross-sectional study 20 NHL diseased children and 10 healthy controls were tested for neurocognitive functions. The selection criteria were: 3 years or more after the end of NHL chemotherapy only regimen, no anaemia, no CNS or systemic diseases. Both patients and healthy controls were examined for global intelligence quotient (IQ), verbal IQ, performance IQ, attention measures, auditory tests, long and short memory, math skills and academic achievement. Results. No decline in global IQ in NHL children compared to healthy controls but there was a significant decline of attention, verbal comprehension and performance IQ. Among 20 NHL diseased children 18 had poor recent and immediate memories while remote memory was normal in 16 children. Young age at diagnosis and treatment intensity were the commonest risk factors. Conclusion. In absence of cranial irradiation, childhood survivors of NHL experience long-term neurocognitive deficits after chemotherapy treatment. Global IQ is not a sufficiently sensitive measure to detect specific CNS deficits in NHL diseased children. The deficits are mainly present in basic neurophysiologic processes of attention and executive functioning. Note: This abstract was not presented at the meeting.
