Few studies exist on thyroid status and ovarian dysfunction, although the prevalence of thyroid disease, particularly hypothyroidism, increases with advanced age and is more common in women. Loss of ovarian function is a lengthy process, and it is well known that follicle-stimulating hormone (FSH) increases with age and is correlated with loss of ovarian reserves. Limited information is available on FSH and thyroid-stimulating hormone (TSH) status in healthy euthyroid women in pre- and postmenopause states. We propose that patterns in FSH levels depend on the menopause state and that a possible relationship with TSH is present in mature women.
Baseline data from the study Health and Menopause in Hispanic Women in Puerto Rico were used. Eligible women were 30-84 years old. Demographic data and lifestyle and health information were collected through a questionnaire, and blood chemistries were analyzed.
In women without thyroid disease, the median TSH was 1.97 mIU/L, and for euthyroid women the median was 1.84 mIU/L; no difference was observed between pre- and postmenopause states. A positive tendency was found between FSH levels and age in this group.
This report compares the value of TSH in Puerto Rican women during pre- and postmenopausal states, and our findings are different from those in other ethnic groups. FSH levels correlate with age, and the general tendency of FSH to increase with age differs according to menopause state. No correlation between TSH and FSH levels was found in this study.

    ABSTRACT: The aim of this study was to determine the association between metabolic syndrome (MetS) and demographic, health, and lifestyle characteristics in a sample of women living in Puerto Rico. The study group consisted of 214 women aged 36 to 82 years, residing in the metropolitan area of San Juan, Puerto Rico. Demographic, reproductive, lifestyle, and metabolic variables were assessed through an annual questionnaire and blood chemistries. MetS was defined according to the criteria set by the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults/Adult Treatment Panel III (NCEP/ATP III) and the International Diabetes Federation (IDF). The overall prevalence of MetS was 24% according to NCEP/ATP III criteria and 33% according to IDF criteria. When using the IDF criteria, 37% of participants older than 51 years have MetS, in contrast to 28% when using the NCEP/ATP III criteria. Obese women have an increased probability of MetS when adjusting for age, education level, menopause status, and/or alcohol use (IDF criteria: estimated odds ratio [OR], 2.68; 95% CI, 1.44-4.97; NCEP/ATP III criteria: estimated OR, 3.42; 95% CI, 1.71-6.84). A higher education level (estimated OR, 0.45; 95% CI, 0.23-0.92 [IDF criteria]) and alcohol consumption (estimated OR, 0.48; 95% CI, 0.23-0.99 [NCEP/ATP III criteria]) seem to provide a protective effect, when adjusting for confounders. Our study confirms obesity as an important risk factor associated with MetS in this sample of women in Puerto Rico. Alcohol consumption and a higher education level seem to decrease the prevalence of MetS. In view of this, patient counseling regarding weight reduction and lifestyle modification should be emphasized in the primary prevention and management of MetS. Additional studies are warranted to further characterize the effect of menopause status on MetS.

    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.
