OBJECTIVE: To identify the prevalence and type of intimate partner violence in women assigned at primary care health and estimates the risks for violence. DESIGN: Case (incident cases)-control. LOCATION: Primary health care unit in Cancun, Quintana Roo, Mexico. PARTICIPANTS: Women over 18years old living in couple at last 12months. MAIN MEASUREMENTS: Validated violence scale for Mexican population was evaluated: total partner violence, physical, psychological and sexual violence. History of violence and sociodemographic variables. Chi square for categorical variables and odds ratio (OR) for risk estimate was determined. RESULTS: The total intimate partner violence was 15.05%, psychological violence in 37.3%. Overall violence, age differences, socioeconomic status, marital status, history of violence and alcohol intake by the partner (P<.05) were observed. The risk increased in over 40 years old (OR: 2.09; 95%CI: 1.07 to 4.11), history of violence (OR: 5.9; 95%CI: 2.8 to 12.44) and alcohol intake by partner (OR=12.38; 95%CI: 2.15 to 29.59). Low socioeconomic status (OR: 0.384; 95%CI: 0.19 to 0.74) and free union (OR: 0.507; 95%CI: 0.27 to 0.95) were relation factors to lower intimate violence partner. CONCLUSIONS: Sexual violence predominated among users of primary health care and the risk that present this behavior increases with the consumption of alcoholic beverages in the couple and a history of violence, but the free union and socioeconomic status were possibility protected for violence.
