Factors that may influence the experience of hot flushes by healthy middle-aged women.

ABSTRACT: Interest in menopausal symptoms in general and hot flushes (HFs) in particular has grown in recent years. This is mostly due to increased awareness and the vast impact these symptoms have on women's lives. Despite the high prevalence of women who experience HFs, a definitive etiology for HFs is yet to be found. Our objective was to review the current literature dealing with associated factors for experiencing HFs and to provide a synthesized overview on this common and often debilitating condition.We systematically searched the English-language literature in the PubMed database using relevant key words and included only those articles that contained information on associated factors for HFs in generally healthy midlife women.Both conflicting scientific results between studies documenting factors that influence HFs and the lack of validated measuring tools make it difficult to truly pinpoint associated factors for HFs. Nonetheless, we identified the following clusters of associated factors: the menopausal stages, sex steroid hormones, other endocrine agents, genetic polymorphisms, race/ethnicity, body mass index (BMI) and obesity, mood disorders, smoking, soy isoflavones and phytoestrogens, alcohol consumption, and physical activity.No single associated factor was consistently identified as having a major role in experiencing HFs. More resources should be directed to develop a unified study system along with multivariable analyses to get a better understanding of this condition, which often imposes a tremendous social and personal toll on the women who experience it.

Project description:ObjectiveVasomotor flushing (hot flushes) is a common menopausal symptom experienced by most women going through the menopausal transition; flushing continues for a variable period in postmenopause. Primarily due to lack of ovarian estrogen, other biomarkers of hot flushes have not been clearly identified. We examined the relationship of hot flushes with ghrelin and adipokines.MethodsBaseline data from two clinical trials, the Women's Isoflavone Soy Health (WISH) trial and Early versus Late Intervention Trial of Estrogen (ELITE), were used in this post hoc cross-sectional study. Both WISH and ELITE had similar study designs, inclusion criteria, and data collection processes. Study participants were healthy postmenopausal women not taking estrogen-based hormone therapy, free of cardiovascular disease, or any other chronic diseases. Both trials used the same hot flush diary in which participants recorded the number of daily hot flushes by severity over a month on average. Serum concentrations of ghrelin, leptin, adiponectin, and resistin were assessed in stored fasting blood samples using highly specific radioimmunoassay. In this analysis, self-reported flushing experience was tested for an association with leptin, adiponectin, resistin, and ghrelin concentrations using logistic regression and mean comparisons.ResultsA total of 898 postmenopausal women from the ELITE and WISH trials contributed to this analysis. Mean (SD) age was 60.4 (7.0) years, body mass index (BMI) 27 (5.3) kg/m, 67% were white, and 47% were within 10 years of menopause. Reported flushing was significantly associated with younger age, lower education, lower BMI, being married, and more recent menopause. Adjusted for these factors other than BMI, women in the highest quartile of ghrelin had significantly greater likelihood of experiencing hot flushes (OR [95% CI] = 1.84 [1.21-2.85]) compared to women in the lowest quartile. The association was more pronounced among overweight or obese women (OR [95% CI] = 2.36 [1.28-4.35]) compared to those with normal BMI (1.24 [0.54, 2.86]; interaction P value = 0.46). The association between ghrelin and hot flushes was similar among early (within 10 y) and late (over 10 y) postmenopausal women. Blood levels of adiponectin and resistin were not associated with hot flushes.ConclusionsHigher concentrations of ghrelin were associated with greater likelihood of hot flushes in both early- and late-postmenopausal women. Leptin, adiponectin, and resistin levels were not associated with hot flushes in postmenopausal women.
