Tanning Capacity and Nicotine Dependence Among African Americans

Area of Science:

• Genetics and Public Health
• Behavioral Science
• Dermatology

Background:

• Facultative melanin and nicotine dependence show a potential link in African Americans.
• Tanning capacity may influence smoking behaviors.

Purpose of the Study:

• To investigate the association between tanning capacity and time to first cigarette (TTFC) in African American smokers.
• To explore tanning capacity as a potential indicator of nicotine dependence.

Main Methods:

• A sample of 150 African American adult smokers was assessed.
• Measurements included reflectometer readings for melanin and tanning capacity, saliva cotinine, and smoking history.
• Time to first cigarette (TTFC) was categorized as within 5 or 30 minutes of waking.

Main Results:

• Individuals smoking within 5 minutes of waking had significantly higher tanning capacity (13.5) than those smoking later (10.3).
• Similarly, those smoking within 30 minutes had higher tanning capacity (12.8) compared to those smoking later (9.6).
• Multivariate analysis confirmed a positive association between tanning capacity and smoking within the first 5 and 30 minutes (OR=1.14 and 1.13, respectively).

Conclusions:

• Tanning capacity is positively associated with nicotine dependence, measured by early smoking initiation, in African American smokers.
• This finding suggests melanin content may play a role in smoking behavior and dependence levels.
• Further research is recommended to explore tanning capacity's impact on smoking cessation and health disparities.
