Abstract
BackgroundSickle Cell Disease (SCD) is a common inherited disease in India. However, more aggregate data regarding the burden and distribution of SCD in India is required.MethodsA search was conducted in five electronic databases between 2000-2023. The quality appraisal was performed using the JBI Critical Appraisal Tool for prevalence studies. The review is reported according to the PRISMA guidelines.Results87 studies were included in this systematic review. The prevalence of SCD, Sickle cell Trait (SCT), and HBS beta thalassemia was estimated to be 1.17% (95% CI:0.79% - 1.75%), 5.9% (95% CI:3.8% - 8.88%) and 0.37% (95% CI:0.17% - 0.83%) respectively. Madhya Pradesh, Chhattisgarh, and Maharashtra have a high prevalence of SCD and SCT. The burden is higher among the tribal communities of India.ConclusionPrioritizing the management of SCD in India through targeted screening among communities of at-risk couples and newborns, and pre-marital counseling and raising awareness can assist in reducing the disease burden.
