Childhood malnutrition, rickets, and anemia: a systematic review and meta-analysis on global prevalence, determinants, and public health implications
Abstract
Background: The world continues to face major health risks through childhood malnutrition and rickets and anemia which hinder the development of physical and mental and immune system functions. The public health system needs to study determinants of health problems and their effective solutions.
Methods: Our research team evaluated 96 studies, which include 153,694 participants from the Middle East and Africa and South and Southeast Asia and high-latitude regions through systematic review. The research team searched for studies in PubMed, Web of Science, Embase, Cochrane Library, and Google Scholar. The research team included observational studies and RCTs and cohort studies and individual participant data meta-analyses in their investigation. The study team evaluated research quality and bias risk through the use of Jadad scale and GRADE system and standard evaluation tools. The research team conducted random-effects meta-analyses to combine hazard ratio data while they used funnel plots and Egger's test to check for publication bias.
Results: The study found that Childhood Nutritional Rickets and Vitamin D/Calcium Status showed strong associations with low calcium and vitamin D intake (HR 1.51, 95% CI 1.26-1.82; I2 = 88%). The research team found that three programs which included Childhood Malnutrition Prevention and Micronutrient Supplementation and Maternal/Early Childhood Nutrition Programs showed protective effects (HR 0.80, 95% CI 0.77-0.84; I2 = 0%; HR 0.91, 95% CI…
