Anaemia prevalence in children newly registered at UNRWA schools: a cross-sectional study

OBJECTIVE: Children 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. SETTINGS: In 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. PARTICIPANTS: 2419 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 MEASURES: Sociodemographic 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). RESULTS: 2419 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). CONCLUSIONS: The 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.
