Four trials that were not combined in meta-analyses suggested that extracts with high ( > 30 mg/d ) levels of genistein consistently reduced the frequency of hot flushes .
BACKGROUND Vasomotor symptoms , such as hot flushes and night sweats , are very common during the menopausal transition .
Hormone therapy has traditionally been used as a highly effective treatment , but concerns about increased risk of some chronic diseases have markedly increased the interest of women in alternative treatments .
Some of the most popular of these treatments are foods or supplements enriched with phytoestrogens-plant-derived chemicals that have estrogenic action .
OBJECTIVES To assess the efficacy , safety and acceptability of food products , extracts and dietary supplements containing high levels of phytoestrogens when compared with no treatment , placebo or hormone therapy for the amelioration of vasomotor menopausal symptoms ( such as hot flushes and night sweats ) in perimenopausal and postmenopausal women .
Vasomotor symptoms among Japanese-American and European-American women living in Hilo, Hawaii
Objective : The Hilo Women 's Health Survey  was design ed and administered to gather baseline data on women 's health in Hilo , HI . This r and omized , cross-sectional study allowed for a focus on ethnic differences in symptom reporting . The results presented here focus on hot flash and night sweat experience among Japanese-American and European-American women . Design : Survey packets were mailed to street addresses associated with parcel numbers pulled r and omly from Hilo tax maps . Of the 6,401 survey packets delivered to households , 1,824 question naires were completed and returned . The results reported here are based on 869 women aged 40 to 60 , of whom 249 described themselves to be 100 % Japanese and 203 described themselves to be 100 % European-American . Logistic regression analyses were used to examine whether the relationship between ethnicity and vasomotor symptoms persisted after controlling for other variables . Results : European-American participants were more likely to have ever experienced a hot flash as compared with Japanese-American participants ( 72 % vs 53 % , P < 0.01 ) . During the 2 weeks before the survey , European-American participants were more likely to have experienced hot flashes ( P < 0.05 ) and night sweats ( P < 0.01 ) . In logistic regression analyses , after controlling for age , body mass index , menopause status , level of education , financial comfort , smoking habits , alcohol intake , exercise , use of hormone therapy , and soy intake , European-American women were still significantly more likely to have experienced hot flashes ( odds ratio = 1.858 ) and night sweats ( odds ratio = 2.672 ) . Conclusions : The results , based on self-reporting of menopausal symptoms , indicate that Japanese-American women report fewer hot flashes and night sweats than European-American women . Japanese-American women reported a higher intake of soy , but soy intake was not associated with fewer vasomotor symptoms
