Prevalence and complications of diabetes mellitus In India - A systematic review

Abstract

Background Diabetes is progressively becoming a vital chronic disease burden worldwide, mainly in developing countries such as India; this necessitates a shift in healthcare priorities and advanced data on the epidemiology and impact of diabetes to help plan and prioritize health programs. We systematically reviewed the literature on diabetes prevalence and its complications in India. Methods This systematic review focuses on diabetes prevalence and complications in India from January 2000 to September 2021. Literature searches were conducted using electronic databases. Results Diabetes prevalence ranged from 2.02% in rural Madhya Pradesh to 40.3% in Tamil Nadu. Diabetes prevalence was significantly higher in urban areas than in rural areas. The prevalence of pre-diabetes varied across Indian states ranging from 2.4% in Meghalaya to 47.6% in Delhi. The prevalence of chronic diabetes complications ranged from 4.8–21.7% for retinopathy, 0.9–62.3%% for nephropathy, and 10.5–44.9% for neuropathy. Conclusions Diabetes is a significant and widespread health problem in India. Dissimilarity in the prevalence of diabetes between individual states is observed. Most diabetes patients experience chronic complications of diabetes. Consequently, it is essential to map the urgent preventive approach to reduce the further increase in areas with high prevalence.

Unveiling the crucial role of intercellular adhesion molecule‐1 in secondary diabetic complications

“…12 In India, the prevalence of DN exhibits a considerable range, from 0.9% to 62.3%. 13 This variability underscores the significant public health implications of DN, as it imposes a considerable burden on the healthcare infrastructure in India.…”

“…Globally, DKD is the primary cause of chronic kidney disease and end‐stage kidney disease, accounting for nearly 50% of all cases 12 . In India, the prevalence of DN exhibits a considerable range, from 0.9% to 62.3% 13 . This variability underscores the significant public health implications of DN, as it imposes a considerable burden on the healthcare infrastructure in India.…”

A review on contemporary nanomaterial-based therapeutics for the treatment of diabetic foot ulcers (DFUs) with special reference to the Indian scenario

“…The national survey reported in various metropolitan cities suggests similar trends, i.e., 11.8% in Kolkata, 11.6% in New Delhi, 9.3% in West India and 6.1% in Kashmir Valley compared to Hyderabad, Chennai and Bangalore, which showed 16.6%, 13.5% and 12.4%, respectively. 27,28 The level of mortality and morbidity due to the incidence of DM is alarming and poses a burden on the healthcare in both society and family. This chronic disease is prevalent across India, posing signicant demands for urgent research interventions at the national and regional levels to mitigate the catastrophic acceleration in DM predicted for upcoming years.…”

Social Support and Medication Adherence Among People with Type 2 Diabetes Mellitus in Central Karnataka, India

“…2 It is crucial to raise awareness, promote early detection, and encourage healthy lifestyle practices to effectively manage and prevent diabetes in India. 3 Effective management including healthy lifestyle management, medication adherence, and regular follow-up is critical for avoiding complications such as cardiovascular disease, renal failure, retinopathy, and neuropathy. 4,5 Social support refers to the assistance, encouragement, and understanding that individuals receive from their social networks, such as family, friends, or support groups.…”
