Soy product intake and hot flashes in Japanese women: results from a community-based prospective study

The association between soy product intake and the occurrence of hot flashes was examined in a cohort of 1,106 female residents of Takayama, Gifu, JAPAN: The women were aged 35-54 years and premenopausal at their entry into the study in 1992. Diet, including intake of soy products and isoflavones, was assessed by means of a validated semiquantitative food frequency questionnaire at study entry. A follow-up mail questionnaire asking about experiences of hot flashes was sent in 1998. During the 6 years of the study period, 101 women had new moderate or severe hot flashes according to the Kupperman test of menopausal distress. After data were controlled for age, total energy intake, and menopausal status, hot flashes were significantly inversely associated with consumption of soy products in terms of both total amount (highest tertile of soy product intake (g/day) vs. lowest: hazard ratio = 0.47; 95% confidence interval: 0.28, 0.79; p for trend = 0.005) and isoflavone intake (highest tertile of isoflavone intake (mg/day) vs. lowest: hazard ratio = 0.42; 95% confidence interval: 0.25, 0.72; p for trend = 0.002). These data suggest that consumption of soy products has a protective effect against hot flashes.

The effect of Valerian on the severity and frequency of hot flashes: A triple-blind randomized clinical trial

ABSTRACT

Valerian is one of the most widely used herbal supplements and a phytoestrogenic herb. The aim of this study was to determine the effect of Valerian on the severity and frequency of hot flashes. This triple-blind, randomized, controlled clinical trial was conducted during a three-month period in Hamadan, Iran, in 60 postmenopausal women aged 45–55 years. Participants were randomly assigned to one of two groups– either placebo or Valerian. An oral Valerian 530 mg capsule was given twice per day for two months. An oral placebo 530 mg capsule (starch) was similarly administered. The severity and frequency of hot flashes were determined by the Kupperman index, before the intervention, one month after, and two months after initiation of the intervention. The severity of hot flashes in the Valerian group was significantly lower than that in the placebo group at one (p = .048) and two months (p = .020) after initiation of the intervention. Compared with the placebo group, the mean frequency of hot flashes was significantly reduced two months after initiating the use of Valerian (p = .033). Health-care providers should consider Valerian to be effective for menopausal women with hot flashes.     

Soy isoflavones attenuate bone loss in early postmenopausal Chinese women

Background Previous studies show that daily doses of 40–99 mg soy isoflavones produce inconsistent effects on preventing estrogen-related bone loss in postmenopausal women. Aim of the study To examined the bone-sparing effect of isoflavones at a higher dose in early Chinese postmenopausal women. Methods A total of 90 eligible women aged 45–60 years were randomly assigned to three treatment groups (30 subjects/group) with daily dosages of 0 (placebo), 84 and 126 mg isoflavones for 6 months. Further inclusion criteria included body mass index <30 kg/m² and Kuppermann Climacteric Scale >15. Bone mineral density (BMD) of the spine and hip were measured using dual- energy X-ray absorptiometry at 0 and 6 months. Serum osteocalcin, bone-specific alkaline phosphatase (BAP) and urinary deoxypyridinoline were examined at 0, 3 and 6 months. Results Mean percent changes in BMD at the lumbar spine (p = 0.114) and femoral neck (p = 0.053) increased with the supplementations of soy isoflavones after adjusting for age, years since menopause, body weight and height, dietary intakes of isoflavones, calcium and protein, physical activities and baseline BMD at the relevant sites. We observed significantly dose-dependent linear relationship between the supplemental isoflavones and percent changes of BMD at the spine (p = 0.042) and femoral neck (p = 0.016) post-treatment, and urinary total deoxypyridinoline (p = 0.014) at 12 weeks but not at 24 weeks after adjusting for the above factors. No significant difference in percent changes in serum osteocalcin (p > 0.05) and BAP (p > 0.05) was found among the three treatment groups at 12-week and 24-week post-treatment. Conclusion There is a significantly dose-dependent effect of soy isoflavones on attenuating bone loss at the spine and femoral neck possibly via the inhibition of bone resorption in non-obese postmenopausal Chinese women with high Kuppermann Scale.     

FSH/LH值与控制性超排卵中卵巢反应性关系的临床研究

目的:探讨FSH/LH值在控制性超排卵(COH)中与卵巢反应性的关系。方法:对336个周期分为超排卵治疗不反应组(34个周期)、低反应组(59个周期)、正常反应组(243个周期),比较3组FSH、LH,以及使用促性腺激素释放激素激动剂(GnRHa)后FSH、LH水平,促性腺激素(Gn)的用量等。激素测定采用酶联免疫分析法。结果:不反应组的FSH基础值为9.9±4.9U/L,分别与低反应组的8.1±5.1U/L及正常反应组的6.6±2.5U/L比较,差异均有统计学意义(P<0.05)。不反应组的FSH/LH基础值为2.8,分别与低反应组(2.1)及正常反应组(1.5)比较差异均有统计学意义(P<0.05)。使用GnRHa启动日不反应组FSH/LH比值为5.1,低反应组为4.1,两者与基础水平比较均有明显增高,而正常反应组增高不明显。结论:GnRHa降调节后,FSH/LH值可用于预测卵巢对Gn的反应性而作为判断COH结果的预测指标。     

Efficacy of soyfoods and soybean isoflavone supplements for alleviating menopausal symptoms is positively related to initial hot flush frequency

Soy has received attention as an alternative to conventional hormone replacement therapy (HRT) largely because it is a unique dietary source of isoflavones. Isoflavones are diphenolic compounds that have both hormonal and nonhormonal properties and are considered to be selective estrogen receptor modulators. The estrogen-like effects of isoflavones in combination with the low reported frequency of hot flushes in Japan has prompted investigation of the effect of soy on menopausal symptoms. The purpose of this review is to evaluate the efficacy of soyfoods and isoflavone supplements for the alleviation of hot flushes. Nineteen trials (13 using a parallel design) involving more than 1,700 women were identified. Six trials were excluded from analysis: two that involved breast cancer patients, two that reported data on severity but not hot flush frequency, one that was not blinded, and one that did not include a control group. Based on a simple regression analysis of the remaining data set (13 trials), there was a statistically significant relationship (P =.01) between initial hot flush frequency and treatment efficacy. Initial hot flush frequency explained about 46% of the treatment effects, and hot flush frequency decreased by about 5% (above placebo or control effects) for every additional initial hot flush per day in women whose initial hot flush frequency was five or more per day. Although conclusions based on this analysis should be considered tentative, the available data justify the recommendation that patients with frequent hot flushes consider trying soyfoods or isoflavone supplements for the alleviation of their symptoms.
