The total effective rate was 96.7% in group A, versus 93.3% in group B and 100.0%in group C, and the rank-sum test showed thatZ=7.675,P=0.022 (P<0.05).ConclusionThe three treatment methods are all effective in treating primary dysmenorrhea, while combining acupuncture and auricular point sticking can approach the optimal effect.

Objective: To examine the exposure to television advertising of unhealthy food among children and adolescents in Beijing, in order to provide a basis for the formulation of marketing management policies with unhealthy food.
