Anaemia prevalence and determinants in under 5?years children: findings of a cross-sectional population-based study in Sudan.

ABSTRACT: BACKGROUND:Early childhood is an age at risk of anaemia and its deleterious consequences. In Sudan, there is limited evidence on the prevalence and determinant of anaemia in under-five children. This study was conducted in Sudan to assess the prevalence of anaemia in children and to identify its determinants. METHODS:We conducted a household survey involving children aged 6?months to 5?years in November 2016. A representative population was sampled across rural, urban and camps settlements across 18 states in Sudan. We used a pre-designed questionnaire data collection. Haemoglobin (Hb) level and malaria infection were checked. In this cross-sectional study, we dichotomized the outcome variable and performed logistic regression analyses. RESULTS:A total of 3094 children under 5?years enrolled in the study, 1566 (50.6%) of them were female and 690 (22.3%) of them were under 2?years old. Anaemia prevalence in the whole cohort (6?months -?

Project description: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.

Project description:BackgroundIron-deficiency anaemia disproportionately affects children in low-income and middle-income areas; Western China is a prime example. Given the health risks associated with childhood anaemia and the large heterogeneity of published studies on this subject, we conducted a systematic review of the evidence regarding anaemia prevalence and associated factors in children under 5 years in Western China.MethodsWe searched for all relevant studies on the prevalence of iron deficiency anaemia in children under 5 years in Western China, obtaining research between 1 January 2011 and 30 June 2021, in English and Chinese from Medline, Embase, PubMed, Web of Science, CNKI, WanFang Data and VIP. Two reviewers independently screened titles and abstracts; three reviewed full texts of relevant articles for data extraction and performed quality assessments. The median prevalence was calculated on unweighted pooling, stratified by region, sex, age and ethnic group. Associated factors and a linear trend chart were conducted to identify trends and research highlights.ResultsAmong the 55 articles included, most were cross-sectional studies (39, 70.91%). The prevalence of anaemia in children under 5 years in Western China ranged from 3.69% to 75.74% (median 42.54% (IQR 25.62%-52.56%)); the highest levels were in Qinghai province: 59.10%-75.74% (median 67.80% (IQR 64.70%-72.75%)); the highest levels were reported in the subgroup of children aged 6-12 months (median 50.09% (IQR 34.35%-59.04%)). Regional contexts, individual sociodemographic characteristics and feeding behaviours, and nutritional programme interventions were factors associated with anaemia prevalence.ConclusionThe prevalence of anaemia in children under 5 years in Western China is concerningly high. For this multiethnic and economically underdeveloped region, more high-quality and prospective studies are needed to inform evidence based and targeted preventive strategies to decrease the high prevalence of anaemia among young children.
