Previous studies of social influences on adolescent smoking have focused on peers and parents, using data collected prior the 1998 Master Settlement Agreement. This study used the 2004 wave of the National Youth Tobacco Survey to examine associations between peer smoking, smoking at home, tobacco-related media exposure, and smoking behavior during early and middle adolescence. Findings indicate that peer smoking and smoking at home remain strongly associated with current smoking among early and middle adolescents, controlling for gender, race/ethnicity and exposure to tobacco industry and anti-tobacco media. The magnitude of the association between peer smoking and current smoking decreases from early adolescence to middle adolescence while the association between smoking at home and current smoking is static across developmental stage. Exposure to tobacco-related media is associated with increased current and former smoking in both early and middle adolescence.

The earliest developmental stage of a fertilized ovum (ZYGOTE) during which there are several mitotic divisions within the ZONA PELLUCIDA.
