Purpose This study aims to assess the relationship between sleep habits and obesity in children. Design/methodology/approach This is an observational cross-sectional case–control study conducted on 100 children aged 6–12 years, selected randomly from the OPC of the Pediatric Hospital, Ain-Shams University. The subjects were subdivided into two groups: the control group of 50 and the target group of children who are classed overweight or obese. Subjects were excluded where the obesity could be explained owing to an endocrinal and/or any identified disease, those who have a medical or psychiatric illness, and those whose parents refused to give consent. All patients had a full history taken, and each child’s parent fulfilled one questionnaire on sleep behaviors. Findings This study found that 72% with bedtime resistance compared to only 14% among the control subjects, 68% of children experienced a delay with sleep onset compared to 14% among controls, 68% experienced sleep duration abnormalities compared to 12% in the control group, 60% of children stated they needed their parents while going to sleep, compared to 12% among controls, 64% of cases suffered from walking during the night compared to 12% among controls, 64% of cases had a Parasomnia compared to 12% among controls, 66% of cases snoring loudly compared to 12% among controls, and 66% suffering from Apnea, compared to 6% in the control group, and 50% of cases had daytime sleepiness compared to 14% among controls. Research limitations/implications It is hoped that this research will be remedied through the adoption of a child-centered approach inspired by the rights to health and play, and the general principles of the Convention on the Rights of the Child (CRC). Practical implications The results showed a strong association between excessive weight and increased risk of sleep problems, which were broadly diffused in the population childhood. Originality/value This current study has given us a base for the overwhelming fact that these children are directly affected by obesity. A chronic medical condition has enormous implications on health and can lead to many associated disease processes.

metastases in multiple organs or locations. Correlations between the location, number, and SUVmax of metastatic lesions and overall survival (OS) were evaluated. Results: Of 136 patients, hepatic metastasis was found in 104, pulmonary metastasis in 36, distant lymph node metastasis in 18, peritoneal metastasis in 15, and bone metastasis in 13. The SUVmax range for metastatic lesions was 4-9.9 (mean 7.8; median 7.5). According to the sub-classification, groups I, II, and III were consisted of 35, 58, and 43 patients, respectively. The patients without bone and distant lymph node metastasis, with metastatic lesion of SUVmax <7.5, from groups I and II had significantly longer OS compared with those of the patients with bone and distant lymph node metastasis, with metastatic lesion of SUVmax 7.5, and from group III. Moreover, multivariate analysis showed that bone metastasis and higher SUVmax of metastatic lesion ( 7.5) were independent prognostic factors for OS. Conclusions: The presence of bone metastasis and high SUVmax of metastatic lesion in staging PET/CT might have prognostic value in predicting the survival of mCRC patients.
