title: [Factors of risk of bacterial vaginosis].
abstract: OBJECTIVE
  To recognise factors in the host that might condition the appearance of the bacterial vaginosis (BV) syndrome, whether gynae-obstetrical factors, habits of sexual conduct, hygiene, or other factors.
  
  
  METHODS
  Cross-sectional, observational study.
  
  
  METHODS
  The study was conducted from January 2002 to June 2003 in the Primary Care Dr. Jose Castro Villagrana Community Health Centre at Tlalpan, Mexico City.
  
  
  METHODS
  968 patients with an active sexual life who had not taken antibiotics for at least 15 days before the study and who were not menstruating at the moment of taking a swab, 859 of whom had a diagnosis of cervico-vaginitis and 109 had no symptoms.
  
  
  METHODS
  Confidential questionnaire and a cervical-vaginal culture. The Amsel criteria were used to make the diagnosis of bacterial vaginosis.
  
  
  RESULTS
  There was 32.9% prevalence of BV. There was a statistically significant association with factors such as age, start of active sexual life, the number of sexual relations per week, the number of sexual partners, and pregnancy.
  
  
  CONCLUSIONS
  Bacterial vaginosis is the main cause of infectious processes in the vagina. Its appearance appears to be linked to factors involving sexual transmission. Interventions to reduce its prevalence and complications are recommended.
