[Prevalence and factors associated with hot flashes in climacteric and post-climacteric women]

A cross-sectional study was conducted on the prevalence of hot flashes and associated factors among women from 40 to 69 years old, from a population-based sample in the city of Pelotas, southern Brazil. A multi-stage sampling process was used, and data were collected through an interview and a self-applied questionnaire. A total of 879 women were included. Point prevalence and lifetime prevalence were 30.1% and 53.2%, respectively. Factors associated with hot flashes were: pre-menopausal status (RP = 2.33) and post-menopausal status (RP = 2.66); age 45-49 years (RP = 1.34) and 50-54 years (RP = 1.42); lower social class (RP = 2.16); no use of a hormonal contraception method after 40 years of age (RP = 1.40); obesity (RP = 1.39) and overweight (RP = 1.32); and not having a partner (RP = 0.80). High prevalence of this symptom indicates that health facilities should be prepared to deal with problems encountered by climacteric women.
