title: Vasomotor symptoms and quality of life in previously sedentary postmenopausal women randomised to physical activity or estrogen therapy.
abstract: OBJECTIVE
  To assess if regular physical exercise or oral oestradiol therapy decreased vasomotor symptoms and increased quality of life in previously sedentary postmenopausal women.
  
  
  METHODS
  A prospective, randomised trial at a University Hospital.
  
  
  METHODS
  75 postmenopausal, sedentary women with vasomotor symptoms were randomised to: exercise three-times weekly over 12 weeks (15 women), oral oestradiol therapy for 12 weeks (15 women) and 45 women to three other treatment arms. Results from the exercise and oestradiol groups are presented here. The effects on vasomotor symptoms and wellbeing were assessed with logbooks and validated questionnaires.
  
  
  RESULTS
  Ten women fulfilled 12 weeks of exercise. The number of flushes was rather unchanged in five women and decreased to 28% (range 18-42%) of baseline in the other five women. Five of the ten women continued to exercise another 24 weeks, thus in all 36 weeks. The mean number of flushes decreased by about 50% in these five women (from 6.2/24 to 3.2 flushes/24 h at 36 weeks). In the same group a score made as the product of reduction in number and severity of flushes decreased by 92% at 12 weeks, 75% at 24 weeks and 72% at 36 weeks compared with baseline. In the estrogen group flushes decreased from 8.4 to 0.8 (P<0.001) after 12 weeks of therapy and remained at this level after 36 weeks. Well-being according to different measurements improved significantly in both groups, albeit more markedly in the estrogen group.
  
  
  CONCLUSIONS
  Apart from many other health benefits regular physical exercise may decrease vasomotor symptoms and increase quality of life in postmenopausal women, but this has to be further evaluated scientifically. Exercise should be introduced gradually to ensure compliance.
