Introduction
Obstructive Sleep Apnea (OSA) is a significant public health issue in India, with rising prevalence linked to factors such as obesity and lifestyle changes. This document compiles key findings on the prevalence of OSA in India and compares it with global statistics.
What is OSA?
Obstructive sleep apnea (OSA) is when you stop breathing during sleep because of a blockage in your windpipe.
You may wake up frequently, which can lead to daytime exhaustion and other frustrating symptoms.
Untreated OSA increases your risk of life-threatening complications.
A healthcare provider might recommend lifestyle changes or using a CPAP machine.
Key Health Hazards due to Sleep Apnea (OSA)
How BAD IS THE SITUATION?????
Overall Prevalence:
A systematic review indicates that approximately 11% of the Indian adult population suffers from OSA, with around 5% experiencing moderate-to-severe OSA (AHI ≥15 events/hour)[1].
Urban vs. Rural:
Studies show that urban populations have a higher prevalence of severe OSA compared to rural areas, with figures reaching up to 19.5% in urban settings[2][3].
Gender Disparities:
Men are more likely to suffer from OSA than women, with reported prevalence rates of 13% for men compared to 5% for women[4].
Undiagnosed Cases:
A significant number of cases remain undiagnosed due to low awareness and underreporting, with only about 2% of affected individuals consulting a physician[5].
Comparison with Global Averages
Globally, the prevalence of moderate-to-severe OSA ranges from approximately 10% to 20% in various populations, indicating that urban India’s rates are comparable or even higher in some studies[4].
Management and Treatment
How is obstructive sleep apnea treated?
Treatment for OSA may include:
Making lifestyle changes like sleeping position adjustments (not sleeping on your back) or maintaining a weight that’s healthy for you
Using a continuous positive airway pressure (CPAP) machine
Wearing oral appliances (mouthpieces)
Undergoing surgery
Obstructive sleep apnea surgery
Common types of surgeries to open your airway and treat OSA include:
Uvulopalatopharyngoplasty (UPPP): Removing tissue from the back of your throat
Tracheostomy: Opening your windpipe to bypass a blockage
Tonsillectomy/adenoidectomy: Removing tonsils or adenoids
Nerve stimulation: Implanting a device to stimulate airway muscles during sleep
