Endothelial NO Synthase Genotype and Risk of Preeclampsia: A Multicenter Case-Control Study

Polymorphisms in the endothelial NO synthase (eNOS) gene have been evaluated as risk factors for preeclampsia. However, data from small studies are conflicting. We assessed whether eNOS genotypes alter the risk of preeclampsia in a population in which the incidence of this disorder is high. A total of 844 young pregnant women (322 preeclamptic and 522 controls) were recruited from 5 cities. Genotyping for the Glu298Asp, intron-4 and –786T→C polymorphisms in the eNOS gene was conducted. Multivariate odds ratios (ORs) were obtained to estimate the association of individual polymorphisms and haplotypes with preeclampsia risk. No increase in the risk of preeclampsia for the intron-4 or –786T→C polymorphisms was observed under any model of inheritance. In contrast, in women homozygous for the Asp298 allele, the adjusted OR for preeclampsia was 4.60 (95% confidence interval [CI], 1.73 to 12.22) compared with carriers of the Glu298 allele. After a multivariate analysis, carriage of the “Asp298–786C-4b” haplotype was also associated with increased risk of preeclampsia (OR, 2.11 [95% CI, 1.33 to 3.34]) compared with carriers of the “Glu298–786T-4b” haplotype. The eNOS Glu298Asp polymorphism and the Asp298–786C-4b haplotype are risk factors for preeclampsia.

Impaired quality of life among middle aged women: a multicentre Latin American study.

BACKGROUND Several studies indicate that quality of life (QoL) is impaired in middle aged women. Assessment of QoL using a single validated tool in Latin American climacteric women has not been reported to date at large scale. OBJECTIVE The Menopause Rating Scale (MRS) was used to assess QoL among middle aged Latin American women and determine factors associated with severe menopausal symptoms (QoL impairment). METHODS In this cross-sectional study, 8373 healthy women aged 40-59 years, accompanying patients to healthcare centres in 18 cities of 12 Latin American countries, were asked to fill out the MRS and a questionnaire containing socio-demographic, female and partner data. RESULTS Mean age of the entire sample was 49.1+/-5.7 years (median 49), a 62.5% had 12 or less years of schooling, 48.8% were postmenopausal and 14.7% were on hormonal therapy (HT). Mean total MRS score (n=8373) was 11.3+/-8.5 (median 10); for the somatic subscale, 4.1+/-3.4; the psychological subscale, 4.6+/-3.8 and the urogenital subscale, 2.5+/-2.7. The prevalence of women presenting moderate to severe total MRS scorings was high (>50%) in all countries, Chile and Uruguay being the ones with the highest percentages (80.8% and 67.4%, respectively). Logistic regression determined that impaired QoL (severe total MRS score > or =17) was associated with the use of alternatives therapies for menopause (OR: 1.47, 95% CI [1.22-1.76], p=0.0001), the use of psychiatric drugs (OR: 1.57, 95% CI [1.29-1.90], p=0.0001), attending a psychiatrist (OR: 1.66, 95% CI [1.41-1.96], p=0.0001), being postmenopausal (OR: 1.48, 95% CI [1.29-1.69, p=0.0001]), having 49 years or more (OR: 1.24, 95% CI [1.08-1.42], p=0.001), living at high altitude (OR: 1.43, 95% CI [1.25-1.62, p=0.0001]) and having a partner with erectile dysfunction (OR: 1.69, 95% CI [1.47-1.94, p=0.0001]) or premature ejaculation (OR: 1.34, 95% CI [1.16-1.55, p=0.0001]). Lower risk for impaired QoL was related to living in a country with a lower income (OR: 0.77, 95% CI [0.68-0.88], p=0.0002), using HT (OR: 0.65, 95% CI [0.56-0.76], p=0.0001) and engaging in healthy habits (OR: 0.59, 95% CI [0.50-0.69], p=0.0001). CONCLUSION To the best of our knowledge this is the first and largest study assessing QoL in a Latin American climacteric series with a high prevalence of impairment related to individual female and male characteristics and the demography of the studied population.

Sexual dysfunction in middle-aged women: a multicenter Latin American study using the Female Sexual Function Index

Objective: The purpose of this study was to assess the prevalence of sexual dysfunction (SD) and associated risk factors among middle-aged Latin American women using one validated instrument. Methods: The Female Sexual Function Index (FSFI) was applied to 7,243 healthy women aged 40 to 59 years who were users of 19 healthcare systems from 11 Latin American countries. An itemized questionnaire containing personal and partner sociodemographic data was also filled out. Results: Mean ± SD age of surveyed women was 49.0 ± 5.7 years, with 11.6 years of schooling on average. There were 55.1% of women who were married, 46.8% who were postmenopausal, 14.1% who used hormonal therapy (HT), and 25.6% who were sexually inactive. Among those who were active (n = 5,391), the mean ± SD total FSFI score was 25.2 ± 5.9 and 56.8% of them presented SD (FSFI total score ≤26.55), with a prevalence varying from 21.0% to 98.5% depending on the center. Centers were grouped in terciles (according to mean ± SD prevalence). The tercile with higher SD prevalence (86.4%) compared with that with lower SD prevalence (32.2%) had significantly older women (49.5 ± 5.3 vs 48.0 ± 5.6 y) with a higher rate of vaginal dryness (60.4% vs 40.8%) and older partners (53.0 ± 6.9 vs 50.2 ± 7.5 y). Similarly, there was a significantly higher rate of married (68.5% vs 63.1%), postmenopausal (49.7% vs 39.3%), and HT-using women (23% vs 9.2%). There were no differences in regard to their health perception, history of oophorectomy, rape, and partner SD rate (27% vs 26.2%). The total FSFI score was significantly lower in the tercile with higher SD prevalence (22.0 ± 5.0 vs 27.5 ± 5.4). Logistic regression analysis was used to determine the odds ratios (95% CIs) for the main risk factors associated with SD among those who were sexually active: bad lubrication, 3.86 (3.37-4.43); use of alternative menopausal therapies, 2.13 (1.60-2.84); partner SD, 1.89 (1.63-2.20); older women (>48 y), 1.84 (1.61-2.09); bladder problems, 1.47 (1.28-1.69); HT use, 1.39 (1.15-1.68); negative perception of female health status, 1.31 (1.05-1.64); and being married, 1.22 (1.07-1.40). Protective factors were higher educational level (women), partner faithfulness, and access to private healthcare. Conclusions: The prevalence of SD in this middle-aged Latin American series was found to be high, varying widely in different populations. A decrease in vaginal lubrication was the most important associated risk factor. Differences in the prevalence of risk factors among the studied groups, several of which are modifiable, could explain the variation of SD prevalence observed in this study.

A large multinational study of vasomotor symptom prevalence, duration, and impact on quality of life in middle-aged women

Objective: The aim of this study was to determine vasomotor symptom (VMS) prevalence, duration, and impact on quality of life in middle-aged women using a validated menopausal tool. Methods: The Menopause Rating Scale (MRS) and an itemized questionnaire containing personal sociodemographic data were used to examine 8,373 women aged 40 to 59 years from 22 healthcare centers in 12 Latin American countries. Results: Less than half (48.8%) of all women studied were postmenopausal, 14.7% used hormone therapy (HT), 54.5% presented VMS of any degree, and 9.6% presented severe/bothersome symptoms. The rate of VMS (any degree) significantly increased from one menopausal stage to the next. HT users presented more VMS (any degree) than did nonusers (58.6% vs 53.8%, P = 0.001). When surgical postmenopausal women were compared, non-HT users displayed a higher prevalence of severe VMS (16.1% vs 9.0%, P = 0.0001). The presence of VMS of any degree was related to a more impaired quality of life (higher total MRS score; odds ratio, 4.7; 95% CI, 4.1-5.3). This effect was even higher among women presenting severe VMS. Logistic regression analysis determined that the presence of severe psychological/urogenital symptoms (MRS), lower educational level, natural perimenopause-postmenopause status, nulliparity, surgical menopause, and living at high altitude were significant risk factors for severe VMS. HT use was related to a lower risk. A second regression model determined that surgical menopause, intense psychological/urogenital symptoms, and a history of psychiatric consultation were factors related to severe VMS persisting into the late postmenopausal stage (5 or more years). Conclusions: In this Latin American middle-aged series, VMS prevalence was high, persisting into the late postmenopausal phase in a high rate and severely impairing quality of life. HT use was related to a lower risk of severe VMS.

Increased menopausal symptoms among Afro-Colombian women as assessed with the Menopause Rating Scale

BACKGROUND Increased frequency and severity of menopausal symptoms have been associated to black race. However, this situation has not been described in any Latin American population. OBJECTIVE Compare frequency and severity of menopausal symptoms among Afro and non-Afro Hispanic Colombian climacteric women. METHODS In this cross-sectional study, healthy Afro and non-Afro-Colombian women aged 40-59 years were asked to fill out the Menopause Rating Scale (MRS) questionnaire in order to compare symptom frequency and intensity. RESULTS A total of 578 women were surveyed (201 Afro-Colombian and 377 non-Afro-Colombian). Mean age of the whole sample was 47.9+/-5.9 years (median 47), with no differences among studied groups in terms of age, parity, and hormone therapy (HT) use. Intensity of menopausal symptoms, assessed with the total MRS score, was found to be significantly higher among Afro-Colombian women (10.6+/-6.7 vs. 7.5+/-5.7, p=0.0001), which was due to higher somatic and psychological subscale scores. In this group, the frequency of somatic symptoms, heart discomfort and muscle and joint problems, was found to be higher than in non-Afro-Colombian women (38.8% vs. 26.8% and 77.1% vs. 43.5%, respectively, p<0.05); equally, all items of the psychological subscale (depressive mood, irritability, anxiety and physical exhaustion) were also found to be higher among black women. On the other hand, compared to black women non-Afro-Colombian ones presented more bladder problems (24.9% vs. 14.9%, p=0.005). After adjusting for confounding factors, logistic regression analysis determined that black race increased the risk for presenting higher total MRS scorings (OR: 2.31; CI 95%: 1.55-3.45, p=0.0001). CONCLUSION Despite the limitations of this study, as determined with the MRS Afro-Colombian women exhibited more impaired quality of life (QoL) when compared to non-Afro-Colombian ones, due to a higher rate and severity of menopausal somatic and psychological symptoms.

Angiotensin-Converting Enzyme I/D Polymorphism and Preeclampsia Risk: Evidence of Small-Study Bias

Background Inappropriate activation of the renin–angiotensin system may play a part in the development of preeclampsia. An insertion/deletion polymorphism within the angiotensin-I converting enzyme gene (ACE-I/D) has shown to be reliably associated with differences in angiotensin-converting enzyme (ACE) activity. However, previous studies of the ACE-I/D variant and preeclampsia have been individually underpowered to detect plausible genotypic risks. Methods and Findings A prospective case-control study was conducted in 1,711 unrelated young pregnant women (665 preeclamptic and 1,046 healthy pregnant controls) recruited from five Colombian cities. Maternal blood was obtained to genotype for the ACE-I/D polymorphism. Crude and adjusted odds ratio (OR) and 95% confidence interval (CI) using logistic regression models were obtained to evaluate the strength of the association between ACE-I/D variant and preeclampsia risk. A meta-analysis was then undertaken of all published studies to February 2006 evaluating the ACE-I/D variant in preeclampsia. An additive model (per-D-allele) revealed a null association between the ACE-I/D variant and preeclampsia risk (crude OR = 0.95 [95% CI, 0.81–1.10]) in the new case-control study. Similar results were obtained after adjusting for confounders (adjusted per-allele OR = 0.90 [95% CI, 0.77–1.06]) and using other genetic models of inheritance. A meta-analysis (2,596 cases and 3,828 controls from 22 studies) showed a per-allele OR of 1.26 (95% CI, 1.07–1.49). An analysis stratified by study size showed an attenuated OR toward the null as study size increased. Conclusions It is highly likely that the observed small nominal increase in risk of preeclampsia associated with the ACE D-allele is due to small-study bias, similar to that observed in cardiovascular disease. Reliable assessment of the origins of preeclampsia using a genetic approach may require the establishment of a collaborating consortium to generate a dataset of adequate size.

Menopausal symptoms appear before the menopause and persist 5 years beyond: a detailed analysis of a multinational study

Objective Few Latin American studies have described menopausal symptoms in detail by means of a standardized assessment tool. The objective of this study was to assess the prevalence and severity of menopausal symptoms and their impact over quality of life among mid-aged Latin American women. Method In this cross-sectional study, 8373 otherwise healthy women aged 40–59 years from 12 Latin American countries were asked to fill out the Menopause Rating Scale (MRS) and a questionnaire containing personal sociodemographic data. Menopause status (pre-, peri- and postmenopausal) was defined according to the criteria of the Stages of Reproductive Aging Workshop. Results Of all the studied women, 90.9% had at least one menopausal symptom (complaint) that they rated. Muscle and joint discomfort, physical and mental exhaustion and depressive mood were highly prevalent and rated as severe–very severe (scores of 3 and 4), at a higher rate than vasomotor symptoms (15.6%, 13.8% and 13.7% vs. 9.6%, respectively). Of premenopausal women (40–44 years), 77.0% reported at least one rated complaint, with 12.9% displaying MRS scores defined as severe (> 16). The latter rate increased to 26.4% in perimenopausal, 31.6% in early postmenopausal and 29.9% among late postmenopausal women. As measured with the MRS, the presence of hot flushes increased the risk of impairment of overall quality of life in both premenopausal (odds ratio 12.67; 95% confidence interval 9.53–16.83) and peri/postmenopausal women (odds ratio 9.37; 95% confidence interval 7.85–11.19). Conclusion In this large, mid-aged, female Latin American series, muscle/joint discomfort and psychological symptoms were the most prevalent and severely rated menopausal symptoms. The symptoms appear early in the premenopause, significantly impair quality of life and persist 5 years beyond the menopause.

Quality of life impairment among postmenopausal women varies according to race

Background. Few studies have addressed the impact of menopausal symptom severity over quality of life (QoL) in Latin American women with different ethnics. Objective. To assess menopausal symptom severity and the QoL among postmenopausal Colombian women with three different ethnicities. Method. Data of healthy naturally occurring postmenopausal Hispanic, indigenous and black women aged 40–59 years who participated in a cross-sectional study filling out the Menopause Rating Scale (MRS) and a general questionnaire was analysed. Results. A total of 579 women were included, 153 Hispanic, 295 indigenous and 131 Afro-descendent. Hispanic women had an average age of 55.3 ± 3.3 years. Indigenous and black women were less educated than the Hispanic ones (2.2 ± 1.8 and 4.6 ± 4.4 vs. 6.4 ± 3.5 years, p < 0.0001). Hispanic women displayed lower total MRS scores (better QoL) when compared to indigenous and black women. Urogenital scoring was worse among indigenous women compared to Hispanic and black women. Black women presented higher MRS psychological and somatic scorings than Hispanic and indigenous women. After adjusting for confounding factors, indigenous and black women continued to display a higher risk for impaired QoL, total MRS score >16 (OR: 3.11, 95% CI: 1.30–7.44 and OR: 5.29, 95% CI: 2.52–11.10, respectively), which was significantly higher among indigenous women due to urogenital symptoms (OR: 102.75, 95% CI: 38.33–275.47) and black women due to psychological (OR: 6.58, 95% CI: 3.27–13.27) and somatic symptoms (OR: 3.88, 95% CI: 1.83–8.22). Conclusion. In this postmenopausal Colombian series, menopausal symptoms in indigenous (urogenital) and black (somatic/psychological) women were more severe (impaired QoL) when compared to Hispanic ones.

Severe menopausal symptoms in mid-aged Latin American women can be related to their indigenous ethnic component

Background Latin American women present more severe menopausal symptoms when compared to those from other regions of the world. Since this population is an ethnic blend of Caucasian and indigenous people, we sought to test the hypothesis that severe menopausal symptoms in Latin American women are associated with an indigenous origin. Objective To assess menopausal symptoms among two specific indigenous Latin American populations. Method A total of 573 natural postmenopausal indigenous women aged 45–59 years (288 Quechua (Peru) and 285 Zenú (Colombia)) living in isolated communities were surveyed with a general questionnaire and the Menopause Rating Scale (MRS). Results The total MRS score was significantly higher among Quechua women as compared to Zenú ones (22.7 ± 5.7 vs. 14.7 ± 2.5, p < 0.0001); both figures were higher than those described for Hispanic or European populations. Quechua women presented more intense somatic and psychological symptoms as compared to Zenú (8.8 ± 2.3 vs. 5.3 ± 1.8; and 7.8 ± 2.4 vs. 3.2 ± 1.7, p < 0.0001); however, both indigenous groups presented similar intense urogenital symptoms (6.1 ± 1.6 vs. 6.2 ± 1.4, not significant). These differences persisted after adjusting for age, years since menopause onset and parity. The percentage of women presenting severe somatic and psychological symptoms significantly increased with aging among Quechua. This was not the case for Zenú women. More than 90%% of indigenous women (Quechua and Zenú) at all age intervals presented severe urogenital scores, a percentage that is much higher than that described in the world literature. Conclusion Severe menopausal symptoms found among Latin American women could be the result of their indigenous ethnic origin; the urogenital domain is the most affected.

Obesity and its relation to depressive symptoms and sedentary lifestyle in middle-aged women

BACKGROUND The prevalence of obesity increases during female mid-life and although many factors have been identified, data from Latin America is lacking. OBJECTIVE To assess factors related to obesity among middle-aged women and determine the association with depressive symptoms, sedentary lifestyle and other factors. METHODS A total of 6079 women aged 40-59 years of 11 Latin American countries were asked to fill out the Goldberg Anxiety and Depression Scale, the Menopause Rating Scale, the Athens Insomnia Scale, the Pittsburgh Sleep Quality Index and a general questionnaire containing personal socio-demographic data, anthropometric measures and lifestyle information. Obesity was defined as a body mass index (BMI) ≥30 kg/m(2). RESULTS Obesity was observed in 18.5% and sedentary lifestyle in 63.9%. A 55.5% presented vasomotor symptoms, 12.2% had severe menopausal symptoms and 13.2% used hormone therapy for the menopause. Prevalence of depressive symptoms was 46.5% and anxiety 59.7%. Our logistic regression model found that significant factors associated to obesity included: arterial hypertension (OR: 1.87), depressive symptoms (OR: 1.57), sedentary lifestyle (OR: 1.50) diabetes mellitus (OR: 1.34), higher number of individuals living at home (OR: 1.31), sleep problems (OR:1.22), anxiety (OR: 1.21), having a stable partner (OR: 1.20), parity (OR: 1.16) and vasomotor symptoms (OR:1.14). A lower risk for obesity was found among women using hormonal contraceptives (OR: 0.69). CONCLUSION Obesity in middle-aged women is the consequence of the interaction of multiple factors. It was associated to hypertension, depressive symptoms, sedentary lifestyle, climacteric symptoms and other factors.
