Establishment of Z Score Reference of Growth Parameters for Egyptian School Children and Adolescents Aged From 5 to 19 Years: A Cross Sectional Study

ObjectiveChildren entering first grade at the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) schools in West Bank, Gaza, Lebanon, Jordan and Syria complete a comprehensive medical examination at UNRWA health centres (HCs) as a requirement for their acceptance. Our study aimed to assess anaemia prevalence and undernutrition indicators among new entrant school children during their preschool medical examination.SettingsIn 2017, we conducted a cross-sectional study in 59 UNRWA HCs, targeting children entering first grade at UNRWA schools in four of UNRWA’s countries of operation (known as fields), namely Gaza, West Bank, Syria and Lebanon.Participants2419 completed the study. Boys and girls living inside or outside Palestine refugee camps were included. Verbal consent was obtained from their parents.Primary and secondary outcome measuresSociodemographic and anthropometric data on each child were collected. Underweight (weight-for-age z-score <−2 SD), stunting (height-for-age z-score <−2 SD), thinness (body mass index-for-age z-score <−2 SD) and obesity (body mass index-for-age z-score >+2 SD) were examined according to WHO growth indicators (5–10 years).Results2419 students (1278 girls and 1141 boys) aged 6.1±0.4 years were examined. The prevalence of anaemia (haemoglobin (Hb) <11.5 g/L) was 25.0% (Gaza: 29.3%; West Bank: 22.0%; Syria: 30.0%; Lebanon: 18.3%). The mean Hb level was 12.0±0.9 g/L. The overall prevalence of stunting, thinness and underweight was 3.2%, 3.5% and 5.6%, respectively, with the highest levels found in Syria (4.3%, 6.3% and 10.1%, respectively). The highest prevalence of overweight was in Lebanon (8.6%), and the lowest was in Gaza (2.6%). Significant differences were found among fields with regard to undernutrition indicators (p=0.001). Also, children with anaemia had significantly higher prevalence of being underweight (5.2%) in comparison with those without anaemia (p=0.001).ConclusionsThe prevalence of anaemia among the surveyed children increased to 25.0%, compared with the previous study conducted by UNRWA in 2005 (19.5%). Thus, it is recommended that Hb testing be included in the medical examination of new entrant school children attending UNRWA schools.

Abstract Background:Growth charts are an important method for evaluating a child's health, growth and nutritional status.Objective:To establish Lambda – Mu- Sigma (LMS) and Z score references for assessment of growth and nutritional status in Egyptian school children and adolescents.Methods:A total of 34,822 Egyptian school children and adolescents from 5 to 19 years were enrolled in a cross sectional randomized study from December 2017 to November 2019 to create LMS and Z score references for weight, height and body mass index (BMI) corresponding to ages. They were selected from different districts in Egypt. Apparent Healthy children with good nutritional history and not suffering from any chronic diseases were included in the study.Results:Egyptian children of both sexes (54.3% boys and 45.7 % girls) from 5 to 19 years old were studied. Then LMS and Z scores for weight for age, height for age, BMI for age of both sexes were represented in detailed tables and graphs. There was no statistically significant difference between the Egyptian Z score charts and the reference values of WHO for weight, height and BMI corresponding to age (P>0.05).Conclusion: This is the first national reference for growth and nutritional assessment using LMS and Z score charts in Egyptian school children and adolescents, this tool is essential for healthcare and research.Key words: Adolescent - Egyptian Z score -Growth parameters- Nutritional status-School children

Abstract Background: Growth charts are an important method for evaluating a child's health, nutrition and development. Objective: To establish Lambda – Mu- Sigma (LMS) and Z score references for assessment of growth and nutrition in Egyptian school children and adolescents. Methods: A total of 31,416 Egyptian school children and adolescents from 5years to 19 years were enrolled in a cross sectional randomized study from December 2017 to November 2019 to create LMS and Z score references for weight, height and body mass index (BMI) corresponding to ages. They were selected from different districts in Egypt. Apparent Healthy children with good nutritional history and not suffering from any chronic diseases were included in the study. Results: Egyptian children of both sexes (56.7% boys and 43.3% girls) from 5 years to 19 years old were studied. Then LMS and Z scores for weight for age, height for age, BMI for age of both sexes were represented in detailed tables and graphs. There was no statistically significant difference between the Egyptian Z score charts and the reference values of WHO for weight, height and BMI corresponding to age (P>0.05). Conclusion: This is the first reference for growth and nutritional assessment in Egyptian school children and adolescents, this tool is essential for healthcare and research. In case of absence of these local charts, we recommend to use the WHO references values rather than other local charts. Key words: Adolescent - Egyptian Z score -Growth parameters- School children

Dental Arch Width

Aim: Objectives: To analyze variations in dental arch width in relation to oral habits. Materials and Methods : Cross sectional study was carried out Department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka with a total number of 600 primary school children of 3-6 years ages of Bangladeshi population. Results: This study was a cross sectional study conducted among the 600 children with 3-6 years old prima- ry school children of Bangladeshi population. According to present study, bottle feeding causes significant reduction in maxillary intercanine width and mouth breathers show significant reduction of both arches. Conclusion: It was observed that the children who had used a bottle had a significant reduction in maxillary intercanine width. Breathing through mouth appeared to be associated with a reduction in the size of both arches. This was more significant in the maxillary intercanine , mandibular intercanine and mandibular molar widths. Therefore to prevent malocclusions, the public should be informed of the harm caused by certain oral habits, the benefits of breast-feeding, and the need to correct bad habits at early life.
