Sun-exposure knowledge and protection behavior in a North Chinese population: a questionnaire-based study

Area of Science:

• Dermatology
• Public Health

Background:

• Sun exposure poses risks for skin disorders.
• Sun protection measures can prevent skin damage.
• Limited research exists on sun exposure knowledge in non-Caucasian populations.

Purpose of the Study:

• To assess sun exposure knowledge, awareness, and behavior in the Chinese population.
• To evaluate sunscreen knowledge and usage patterns.
• To compare findings with existing data from Caucasian populations.

Main Methods:

• A self-administered questionnaire with 13 multiple-choice questions was used.
• The questionnaire assessed knowledge, awareness, and protection behaviors related to sun exposure.
• It also evaluated knowledge of sunscreens and their application.

Main Results:

• 623 volunteers (38.2% men, 61.8% women) participated.
• Correct answers on sun exposure knowledge ranged from 50% to 80%.
• Sunscreen use was reported by 58.8%, followed by protective clothing (49.3%). High SPF (mean 27.7) and PA (mean 2.3) sunscreens were common. 52% found tanning unattractive.

Conclusions:

• The Chinese population shows broad awareness of sun exposure dangers.
• High-SPF and high-PA sunscreens are prevalent among Chinese users.
• Significant sex differences and distinct attitudes toward tanning compared to Caucasians were observed.
