Which factor is associated with an increased risk of developing Obstructive Sleep Apnea (OSA)?

• A. Increased caffeine consumption
• B. Increased neck circumference
• C. Decreased sleep duration
• D. High sodium diet

Answer: (B)

Increased neck circumference is associated with an increased risk of developing Obstructive Sleep Apnea (OSA) due to its connection to the structural aspects of the airway. A larger neck circumference often indicates an accumulation of fatty tissue around the neck, which can lead to partial or complete obstruction of the airway during sleep. This anatomical change can impair normal breathing patterns, causing the characteristic snoring and episodes of apnea that define OSA.

While other factors like decreased sleep duration and high sodium diet can impact overall health and may lead to weight gain, they are not as directly connected to the anatomical features influencing the risk for OSA. Increased caffeine consumption does not have a clear link to the physical changes that cause sleep apnea, making neck circumference a more critical indicator of risk in this context.
