Which of the following is a primary risk factor for drowning?

Lack of supervision is a significant primary risk factor for drowning because it directly impacts the ability to respond to emergencies in aquatic environments. When individuals, particularly children, are not supervised while swimming or near water, the likelihood of drowning incidents increases dramatically. Supervision helps ensure that someone is present to monitor behavior, recognize danger, and react quickly in the event of an emergency.

On the other hand, swimming lessons can actually reduce the risk of drowning by educating individuals on water safety and swimming skills. Good weather conditions generally create a safer environment for swimming, and wearing flotation devices is intended to increase safety by helping individuals stay afloat. Therefore, adequate supervision is essential to prevent drowning accidents and is considered a primary risk factor.
