Prevalence and associated factors of at risk of anemia among children under five in Northeast Thailand using noninvasive hemoglobin screening in a cross sectional study
Abstract
Pediatric anemia remains a significant public health challenge in Northeast Thailand, where hemoglobinopathies and nutritional deficiencies coexist. Early identification of children at risk of anemia is crucial to prevent developmental and health consequences. This study assessed the prevalence of children under five being at risk of anemia using Masimo Rad-67® with Rainbow DCI-mini Sensor, while evaluating the association between caregivers’ knowledge, attitudes, and practices on complementary feeding and childhood anemia. A clustered randomized cross-sectional study was conducted involving 2,000 child-caregiver pairs (aged 6 months to 5 years) in Northeast Thailand from September 2022 to March 2023. Non-invasive hemoglobin measurement was used, with anemia risk defined as spectrophotometry hemoglobin (SpHb) < 13.0 g/dL. Data collection included demographic characteristics, natal history, and feeding practices. Additionally, a survey was conducted to assess associated factors of anemia and caregivers’ attitudes, knowledge, and practices regarding complementary feeding. The study found a 36.9% prevalence of at-risk anemia. Key predictors included age under 24 months (adjusted OR 2.1, 95%CI 1.7–2.6), maternal thalassemia trait (adjusted OR 1.8, 95%CI 1.4–2.3), and wasting (adjusted OR 1.6, 95%CI 1.2–2.1). Iron supplementation was a protective factor. Despite 48.2% of children receiving iron supplementation per government policy, only 24.6% met the daily iron intake according…
