Preliminary

marital characteristics, condom negotiation self-efficacy, and sexual preparatory behaviors. Results: Socio-demographic variables (age and education) explained 16.1% of variance ( (cid:2) F(2, 170)=16.30, p <.001), and marital variables, ‘‘marital status’’ and ‘‘talking about AIDS with partner’’ explained 22.3% of additional variance ( (cid:2) F(2, 168)=30.36, p <.001) in preparatory behaviors. The final model with condom negotiation self-efficacy explained 11.7% of additional variance ( (cid:2) F(1, 167)= 39.14, p <.001), this being the most important correlate in the model ( (cid:2) = .48). We observed that higher condom negotiation self-efficacy is associated with higher levels of preparatory behaviors. The overall model explained 48.6% of variance in sexual pre- paratory behaviors. Conclusions: These results seem to support an exploratory predictive model of sexual preparatory behaviors that can inform interventions directed at behavioral change among Mozambican women at sexual risk. Background: Physical inactivity is the fourth leading cause of death in the world. The concept of medical prescription of physical activity (PA) adapted now appears in a law, which specifies the central role of the family physician. The needs of the general practitioners (GP) about prescription of PA have not been studied. Aim: To assess the knowledge and needs of GPs regarding the medical prescription of PA. Methods: This is a transversal observational epidemiological study of GPs working in the departments of Hauts-de-Seine (92) and Val-de-Marne (94) near Paris. A questionnaire was sent by mail or email. Results: Conclusions:
