BACKGROUND: Lockdown and school closure related to the coronavirus disease 2019 (COVID-19) have unfavorable effects on children and adolescents. AIM: This study was conducted to survey the changes in dietary pattern and related health factors in Egyptian children and adolescents during the COVID-19 outbreak closure. MATERIALS AND METHODS: Data were collected through a dietary pattern, eating behavior, and physical activity electronic questionnaire conducted through social media sites, targeting parents of children and adolescents after two whole months of lockdown and school closure in Egypt. RESULTS: This study included 765 participants, 31.8% noted increased appetite, 45.6% reported increased sweets and unhealthy food consumption, and 37.6% showed increased frequent snacking between meals. Alongside 53.1% showed increase in late snacks during night after COVID-19 closure. The majority of our participants 82.0% noted associative change in eating behavior with boring and 94.6% revealed increased usage of electronics and screen time. This study showed significant positive correlation between increased appetite and mobile screen time, laptop screen time, and video gaming. Increased sweets and unhealthy food consumption was positively correlated with TV watching and mobile screen time. A significant positive correlation was revealed between uncaring about eating fruits and vegetables and increase screen time for each of mobile, and laptop and remote learning. Furthermore, there was positive correlation between decreased protein serving intake and each of mobile screen time and remote learning. TV watching and laptop screen times showed positively significantly association with frequent snacking between meals. Mobile screen time, TV screen time, and video gaming were positively significantly correlated with late night snacking. CONCLUSIONS: The present study concluded prolonged lockdown leads to changes in eating patterns, related to contributing factors of physical inactivity and prolonged screen time.

Background Coronavirus Disease Pandemic 2019 has a pervasive effect on all health aspects include psychological and mental health. This study aimed to assess the hidden stressful impact of COVID-19 pandemic on Egyptian children and adolescents’ lifestyles 2 months after lockdown in Egypt by detecting symptoms of anxiety and sleep disorders. Online questionnaire was used by snowball sampling approach 2 months after lockdown targeting children and adolescents. Results The overall mean Sleep Disturbance Scale for Children score (SDSC) in participated groups was 44.6 ± 11.72. Of 765 participants 502 (65.6%) showed the symptoms suggestive of sleep disorder. Disorders of initiating and maintaining sleep were the most common among participants as 168 (33.4%) of them were suffering from it while 79 (15.7%) children were suffering from excessive somnolence. Linear stepwise regression revealed that anxiety score, understanding safety measures, and following strict quarantine measures significantly predicted SDSC (p = 0.001, 0.009, 0.046). Significant positive correlations were found between SDSC and extra screen usage, understanding safety and quarantine measures, anxiety signs, and change in child lifestyle with (p = 0.029, 0.010, 0.001 and 0.001) sequentially. Significant positive correlation was found between family income affection, SDSC, and anxiety with p value (00.001, 00.4). Conclusion Child deprived of his or her normal lifestyle is vulnerable to develop anxiety symptoms and sleep disturbances. Low income, extra screen time, and restricted quarantine measures are all contributing factors that influence children and adolescent’s mental health.

Childhood obesity has been linked to an increase in fracture risk, so the impact of obesity on bone metabolism is becoming a focus of attention to identify factors that may affect bone health in obese children. Therefore, this study aimed to examine the association between serum 25-Hydroxy vitamin D [25(OH) D], adipokines and bone status in obese children. This case control study was executed in the Child Health Clinic in Medical and Scientific Centre of Excellence, National Research Centre (NRC), 100 obese and 80 non-obese age- and sex-matched children were enrolled in our study with mean age of (10.12±2.34 & 9.62±1.67 years) respectively. Anthropometric measurements, femoral neck bone mineral density (BMD) and its Z-score, bone mineral content (BMC) were measured using dual-energy X-ray absorptiometry (DXA) in relation to body weight (kg), we also determined serum 25(OH) D, adiponectin, leptin and lipid profile. HOMA-IR was calculated to assess insulin resistance. It was found that BMC and BMD Z-score adjusted for weight were significantly lower in obese children as compared to controls (all p<0.05). Obese children had lower levels of 25(OH) D and adiponectin (P<0.01), while higher levels of leptin, total cholesterol (TC) and triglycerides (TG) compared to controls (P<0.01). Both BMC and BMD Z-score showed positive association with 25(OH) D and adiponectin (P<0.01) and negative association with HOMA-IR, TG and TC (P<0.05). Linear regression analysis showed that 25(OH) D was the most effective factor predicting BMD Z-score and BMC in obese children. It is concluded that, obesity is negatively related to bone health in childhood. Those obese children are at increased risk for vitamin D insufficiency, which shows an obvious relationship to lower bone mass, raising the question of supplementation to prevent the deleterious effect of its deficiency on bones and reducing future risk of fracture and osteoporosis.

BACKGROUND: Increased incidence of pediatric end-stage renal disease (ESRD) with associated serious consequences indicating a major public health problem. Malnutrition and uremic wasting are leading causes of growth impairment and increasing morbidity and mortality of pediatric ESRD patients, predominantly those on regular hemodialysis (HD). Ghrelin and obestatin, which are known appetite regulatory hormones, might have a pivotal role in uremic wasting and growth impairment in hemodialyzed children. AIM: The aim of the present study was to measure serum unacylated ghrelin (UAG) and obestatin and to investigate their roles in the growth impairment of Egyptian hemodialyzed children. SUBJECTS AND METHODS: The study included 50 hemodialyzed and 40 healthy children recruited from the Department of Nephrology, Pediatric Hospital, Ain Shams University. Full clinical examination and measurement of anthropometric indices were done. Routine labs were done as well, with an assessment of serum levels of obestatin, UAG, and insulin by enzyme linked immunosorbent assay. Furthermore, we determined fasting serum glucose and lipid profile with the calculation of homeostasis model assessment for insulin resistance (HOMA-IR). RESULTS: Anthropometric measurements were statistically significantly decreased in the hemodialyzed group than that of the control group (p < 0.05). Weight z-score was the most affected anthropometric parameter (37 patients = 74% with underweight and 13 patients = 26% with normal weight). The hemodialyzed children showed a significant increase of UAG, obestatin, insulin, glucose, HOMA-IR, and TG, while a significant decrease of HDL-cholesterol and albumin (p < 0.01). UAG had a negative correlation with Wt-z score, Ht z-score, fat mass %, albumin, and TG while obestatin was inversely correlated to Wt-z score, BMI z-score, waist circumference, and waist-height ratio (W/H). CONCLUSION: UAG and obestatin hormones were elevated in a group of Egyptian children on regular HD. These hormones were strongly related to the impairment of renal functions, and anthropometric parameters, dyslipidemia, hypoalbuminemia, and insulin resistance in these pediatric hemodialyzed patients.
