Background  Women after menopause increase risk for cardiovascular disease and several factors may be related. The purpose was to study biological and psychosocial factors associated with early cardiovascular damage in pre- and postmenopausal women, assessed with carotid intima-media thickness vs flow-mediated dilatation.    Methods  Women 45 to 57 years old were grouped in the pre- ( n  = 60), early ( n  = 58) and late post-menopause ( n  = 59). Anthropometric, metabolic and hormonal data were registered, as well as measures of depression, anxiety, submission, perceived stress, and sleep alterations. Heart Rate Variability was recorded to obtain the information regarding sympathovagal balance. Carotid intima-media thickness and flow-mediated dilatation were assessed by ultrasound. Two-way ANOVA and multiple regression model were used.    Results  At late postmenopause, the carotid intima-media was thicker ( p  < 0.001) and flow-mediated dilatation decreased ( p  < 0.001). Carotid intima-media thickness was associated positively with age (p < 0.001), submission score ( p  = 0.029), follicle stimulating hormone levels (p < 0.001), and body mass index ( p  = 0.009). Flow-mediated dilatation was associated only with age (p < 0.001). Regarding heart rate variability, the time domain pNN50 measurement was higher in premenopausal women ( p  = 0.001), Low Frequency (LF) was higher in the two groups of postmenopausal (p = 0.001) and High Frequency (HF) higher in the early postmenopausal women ( p  = 0.042).    Conclusions  Under our conditions carotid intima-media thickness had higher predictive value for early cardiovascular damage at menopause. The finding of the association of the submission score, indicates de influence of stress on vascular damage.
