Overweight and obesity prevalence among upper Egypt primary schools' children using Egyptian and CDC growth charts.

BACKGROUND: Monitoring of overweight and obesity among children; by using different growth charts; is fundamental to disease prevention and health promotion. AIM OF THE STUDY: To determine overweight and obesity for age among primary school children in Upper Egypt using the Egyptian and CDC growth charts. SUBJECTS AND METHODS: Cross-sectional research design was used and conducted at 20 public primary schools in four Upper Egypt governorates. The sample size was 5300 children who selected by multistage sampling technique. Interview questionnaire included personal data and anthropometric measurements (height, Weight and BMI) and Egyptian and CDC growth charts. RESULTS: The percentages of children being overweight and obese for age using Egyptian chart were low compared to CDC charts (1.9 vs 4.6%, 8.5% vs. 3.3%, 8.7% vs 3.3% respectively). According to Egyptian chart 5.2% and 5% from total studied boys and girls were overweight and obese respectively, while in CDC growth chart 13.3% and 10.5% from total studied boys and girls respectively. CONCLUSION: It concluded that there were remarkable differences between CDC and Egyptian growth charts references in the classification of child overweight and obesity. The CDC growth chart evident much higher prevalence among the studied children compared to the Egyptian growth chart. RECOMMENDATION: Periodic development and reconstruction of national growth chart to represent the growth pattern of all geographical areas in Egypt. Also, further researches needed to assess the differences of both international and national references.

Molecular detection and phylogenetic analysis of newly emerging foot-and-mouth disease virus type A, Lineage EURO-SA in Egypt in 2022.

A newly emerging and exotic foot-and-mouth disease virus (FMDV) caused a recent outbreak of serotype A in Egypt in 2022, which affected cattle and water buffalo. Previous phylogenetic studies on FMDV circulating in Egypt have mainly focused on genomic regions encoding the structural proteins which determine FMDV serotype. No study has yet determined structural proteins sequences of the newly emerging Europe-South America (EURO-SA) lineage which was recently isolated from Egypt during a routine surveillance in 2022. The objective of the current study was to analyze the structural proteins of the Venezuelan type which belongs to EURO-SA. The new isolate was related to serotype A lineage Euro-South America. Phylogentic analyses have reveled that the newly isolated lineage samples were closely related to reported sequences that have been identified in Venzuela and Colombia. Analysis of structural protein sequences revealed the recent isolates belong to prototype strain A24 Cruzeiro. Notably, nucleotide sequences of the Egyptian isolate was related to Venezuelan, Brazilian, and Colombian strains with identity not exceeding 90%. The divergence which appears in the genetic identity of the Egyptian A/EURO-SA lineage from other related strains may be attributed to the absence of Euro-SA lineage sequence from Egypt. The present study is the first report on the detection of EURO-SA lineage in Egypt. The recent detection of the EURO-SA lineage samples may be explained due to imported animals from Colombia or Brazil which share geographical borders with Venezuela. The findings of the present study highlight the significance of continuous monitoring of FMDV in Egypt for newly emerging FMDVs.
