title: [Adiponectin levels in perimenopause].
abstract: BACKGROUND
  Adiponectin is an hormone produced exclusively in adipose tissue, that actively acts in carbohydrate and fat regulation processes.
  
  
  OBJECTIVE
  To determine adiponectin levels in a women's group.
  
  
  METHODS
  Transversal study in 22 amenorrheal women with climacteric symptoms, and without estrogen therapy. There were excluded those with diabetes, hypertension, dislipoproteinemia and obesity. Significant differences among values of adiponectin in perimenopausal and young women during follicular phase of menstrual cycle were analyzed by means of Student t test.
  
  
  RESULTS
  Adiponectin concentration in perimenopausal women was 14.1 +/- 8.2 microg/mL (M +/- SD), without meaningful difference compared with young women.
  
  
  CONCLUSIONS
  It wasn't significant variation in adiponectin levels compared with normal menstrual cycle women. Further studies are necessary to establish adiponectin effect in postmenopause and its relation with the cardiovascular diseases.
