Attitudes to menopause and hormone replacement therapy among Asian and Caucasian women general practitioners

This study was conducted to investigate body-mass-index (BMI), insulin resistance and beta cell function in a group of pregnant women. Two hundred and twenty-three consecutive women with an abnormal 50 g glucose challenge test in the third trimester were studied. All underwent oral glucose tolerance testing; 97 had a 100 g test and 126 a 75 g test. Fasting insulin was measured. Insulin resistance and beta cell function were calculated using the homeostasis model. Among the 136 Caucasian, 60 Asian, 11 Indian and 16 Arabic women studied, there were no age differences. Arabic women had higher parity (p < 0.05). Asian women had lower BMI than Caucasian (p < 0.001), Indian (p < 0.01), and Arabic women (p < 0.01). Women with gestational diabetes had higher insulin resistance than women with normal glucose tolerance (2.9+/-4.0 vs. 2.3 +/- 2.5 p = 0.025). Women with gestational diabetes tended to have lower beta cell function 199 +/- 203 vs. 247 +/-380 p = 0.08). Asian women had higher glucose levels than Caucasian women after 50 g challenge (8.9 +/- 2.1 mmol/1 vs. 8.6 +/- 1.6; p = 0.034). Asian women were more likely to have gestational diabetes than Caucasian women (31.7% vs. 14%; p = 0.02). Fasting glucose and insulin were comparable in Asian and Caucasian women. Mean insulin resistance and beta cell function in Asian and Caucasian women were not significantly different. We concluded that Asian women had lower BMI than Caucasian women. Women with gestational diabetes were more insulin resistant. Insulin resistance and beta cell function in Asian and Caucasian women are similar. Gestational diabetes in Asian women is of similar aetiology to that seen in Caucasian women, but occurs at a lower BMI.

Background: A major area of innovation in breast cancer (BC) is improving risk models for screening efforts. The University of California Athena Breast Health Network uses several risk models, including the Gail model [PMID: 10491430]. The Breast Cancer Surveillance Consortium (BCSC) model [PMID: 18316752] which integrated information on breast density was developed and validated by UCSF investigators and reports Asian-specific risk. The Peking Union Medical College (PUMC) model [PMID: 22662004] is developed from a case-control study in China and reports BC risk in Chinese women. Risk factors and their respective weights included in these models are different. Methods: From December 2012 to April 2014, 2,305 women without previous history of BC and consented to research were enrolled in the UCSF Athena screening cohort. Questions asked included risk factors used in Gail, BCSC and PUMC model, such as age, age of menarche (AOM), age at first live birth, body mass index (BMI), breast biopsy, breast density, hormone replacement therapy (HRT), oral contraceptives (OCP). Women were considered high risk when: Gail &amp;gt; 1.67% 5-year risk, BCSC &amp;gt; 1.67% 5-year risk, PUMC score &amp;gt; 30 (equals &amp;gt;0.20% 1-year risk) respectively. The distribution of the risk factors and the high risk population percentage were compared between Chinese women versus non-Chinese Asian and Caucasian women. Results: 402 Asian women comprise 17.4% of all 2,305 Athena screening cases with 234 Chinese, and 168 non-Chinese Asian (NCA). Differences in risk factor distribution were observed for the following: positive family history was observed 23% for Caucasian, 15% for Chinese and 13% for NCA (p=0.001), and previous breast biopsy was 27%, 17% and 22% respectively (p=0.002). Ever use of HRT was 36% in Caucasian, 17% in Chinese and 11% in NCA (p&amp;lt;0.001). Ever give birth was 68% in Chinese, 65% in NCA, and 57% in Caucasian (p=0.001), while the age at first live birth &amp;lt;30 was 35%, 33%, and 26% correspondingly (p=0.001). Breast density appeared to be higher in Asian women (p=0.095). The high risk proportions by each model are given in Table 1.

Asian ethnicity is associated with reduced pregnancy outcomes after assisted reproductive technology

This study aimed to describe the prevalence of hormone replacement therapy (HRT) use by women doctors and doctors' wives in northern Italy, to explore the relationship between their personal characteristics and HRT use, and to gather information about the use of alternative remedies. A questionnaire was mailed to all physicians born between 1935 and 1955 included in the database of the Medical Register of Turin County (Northern Italy). The questions were meant to explore medical, behavioral, and professional characteristics; personal use of HRT; reasons for and against HRT use; side effects and use of other therapies. 56.5% of postmenopausal women who completed the questionnaire had used HRT and 68.3% of them were current users. The median duration of HRT use was 3.7 years. Only 18.5% of the women had used HRT for 5 years or more; in this case, HRT was started significantly earlier than in the other groups. More than 50% had taken oral HRT, while 39% had used patches; estrogens only had been taken by 21.9%. HRT users had a significantly lower basal body mass index and more vasomotor and dystrophic symptoms at menopause onset compared with non-HRT users. More women on HRT were in good physical health and had an active sex life. Previous breast cancer and family history of cardiovascular diseases were inversely associated with HRT use. The main reason for not taking HRT or stopping it was fear of breast cancer (43.7% and 34.8%, respectively); irregular bleeding and weight gain were also frequently reported as a reason for HRT (30% and 22%). Overall, 22% of women had used alternative drugs to alleviate menopausal symptoms or prevent menopause-related diseases, mainly tibolone (21% among never HRT users and 2% among HRT users; p=0.015) and phytoestrogens.The prevalence and duration of use of HRT by Italian physicians is consistent with the available data from other Western countries, and is much higher than in the general population. This is in contrast with the very low prevalence of use in the general population and may lead, in the near future, to a larger use of HRT in Italy.

This study investigated secular trends in socio-economic status (SES) differentials in Australian suicide (1979-2003), which includes overall declines in male suicide from 1998. Suicide rates were stratified by approximate equal-population quintiles of area-based SES for the period 1979-2003 and examined across five quinquennia, centred on each Australian Census from 1981 to 2001, to determine if (1) SES differentials in suicide have persisted over time, and (2) if SES differentials have widened or narrowed. Suicide rates (per 100,000) were adjusted for confounding by sex, age, country-of-birth, and urban-rural residence using Poisson regression models, and secular changes in SES differentials were assessed using trend tests on suicide rate ratios (low to high SES quintiles). Socio-economic status (SES) differentials persisted across the study period for both males and females after adjusting for the effects of age, migrant status, and urban-rural residence, with the largest differences between low and high SES groups evident in males, and especially young males (20-34 years). For males, suicide rates increased significantly in all SES groups until 1998, before diverging significantly in the most recent 5-year period, particularly in younger males (P<0.0001). In young males, suicide rates in the most recent period increased in the low SES group from 44.8 in 1994-1998 to 48.6 in 1999-2003 (an 8% increase). In contrast, suicide rates in the middle SES group decreased from a peak of 37.3 to 33.5 (a 10% decrease), and in the high SES group from a peak of 33.0 to 27.9 (a 15% decrease). A similar statistically significant divergence of a lesser magnitude was also evident in all age males and younger females (20-34 years). This study shows that SES differentials in suicide persisted in Australia for most of the period 1979-2004. The decline in suicide in young males in the most recent quinquennium was limited to middle and high SES groups, while the low SES group displayed a continued increase. The continued increase in suicide in low SES males has implications for social and economic intervention and suicide control programs.

Objectives:Little is known about ethnic differences in bone geometry, nor their association with 25-hydroxyvitamin D (25(OH)D), especially among ethnicities living in the same country. The purpose of this preliminary study was to investigate differences in bone geometry at the radius and tibia, as well as in 25(OH)D status, between Arab (A), South Asian (SA), and Caucasian (C) premenopausal women residing in the UK. The potential association between 25(OH)D concentration and indices of bone geometry was also assessed.Methods:Fifty-seven healthy premenopausal women (17 A, 18 SA, and 22 C), ranging in age from 18 to 51 years, underwent assessment of their volumetric bone mineral density and 25(OH)D concentration. Ethnic differences were assessed using ANOVA. Spearman’s rho was used to analyze associations between 25(OH)D and pQCT bone variables.Results:At the 4% radius, Arab women had a lower BMC, as well as a smaller total bone area and trabecular area than did Caucasian women. At the 4% tibia, Arab women had a lower total vBMD than did South Asian women. Serum 25(OH)D among Arab (36.5(22.4SD)) and South Asian (31.4 (16.8SD)) women was significantly lower than in Caucasian women (81.9(20.0SD)) (P < 0.05). There were no statistically significant correlations between 25(OH)D and pQCT bone variables in any ethnic group.Conclusions:This study suggests a possible need for attention to bone health in premenopausal Arab women as well as improvement in Vitamin D status in Arab and South Asian populations.

Polycystic ovary syndrome (PCOS), insulin resistance and overall mortality due to diabetes and coronary artery disease are higher in South Asians than in Caucasians. Aims: We compared the prevalence of the C677T and A1298C single nucleotide polymorphisms in the methylenetetrahydrofolate reductase gene in South Asian and Caucasian women, its association with folate and homocysteine (Hcy) metabolism, and its relevance to future atherogenic events. Methods and results: 71 women were recruited for the study: South Asian PCOS (21) plus controls (9) and Caucasian PCOS (25) plus controls (16). Anthropometric and laboratory parameters were compared. South Asian PCOS women were significantly hyperandrogenic and exhibited a greater degree of insulin resistance. Caucasian PCOS women had higher plasma Hcy concentrations with a 1.9 times higher frequency of the T allele than the South Asian PCOS group. In the presence of this variant allele, plasma Hcy levels appear to be higher in both PCOS groups. The South Asians had a 1.8 times higher frequency of the C allele than the Caucasians; however, the overall frequency was comparable in the two PCOS groups. The frequency of homozygosity, i.e. TT677 and CC1298, was 7.2% and 4.9% in the Caucasians and 0% and 16.6% in the South Asian recruits, respectively.Dietary inadequacies in the South Asian women can influence their plasma folate and B12 concentrations resulting in hyperhomocysteinemia which, in combination with dyslipidaemia and insulin resistance, can lead to long-term atherogenic consequences. Conclusions: Current data suggests that the mechanisms of atherothrombosis have separate pathways in the two ethnic groups. Larger studies exploring the current theme need to be carried out in the PCOS groups to obtain adequate insight.

Personal use of hormone therapy by postmenopausal women doctors and male doctors’ wives in Italy after the publication of WHI trial

Ethno-cultural risk of ante-natal lead exposure among South Asian women in the UK.

The urinary ratio of 6-beta-hydroxycortisol/cortisol has been used as a noninvasive probe for human cytochrome P450 3A4 isoforms (CYP3A4). Ethnic-related differences in the ratio have not been evaluated. The aim of this study was to determine if there are differences in the ratio between Asian and Caucasian women over a menstrual cycle. First-morning urine samples were collected every other day starting from the second day of menstruation for a complete menstrual cycle from 15 Asians and 16 Caucasian women who were 18 to 40 years old, healthy, nonsmoking, and alcohol and drug free, including oral contraceptives. Urine concentrations of 6-beta-hydroxycortisol and cortisol were measured by high-pressure liquid chromatography (HPLC). For statistical analysis, three phases of the menstrual cycle were evaluated: menstruation (days 1-4), follicular or postmenstruation (days 6-10), and the luteal phase (days 21-24) based on the average menstrual cycle (28 days). Statistical analysis was performed by an independent sample t-test using the Bonferroni correction for repeated measures. Large intersubject and intrasubject variations of the 6-beta-hydroxycortisol/cortisol ratios were observed during the menstrual cycles in both ethnic groups. Asian women had a statistically significant lower ratio than Caucasian women did for all three phases of the menstrual cycle: 2.2 +/- 1.1 versus 5.1 +/- 3.5, 2.1 +/- 1.1 versus 6.0 +/- 4.9, and 2.8 +/- 1.6 versus 5.6 +/- 3.0 for the menstruation, follicular, and luteal phases, respectively. The two- to threefold lower 6-beta-hydroxycortisol/cortisol ratios in Asian women suggest that Asian women may have a lower CYP3A activity compared with Caucasian women. Differences in ethnicity may mask potential gender-related effects if ethnic background is not evaluated as a contributing factor.

Health professionals face two complicated but contradictory epidemics: obesity and osteoporosis (OP). While obesity is obvious, OP progresses silently affecting one in two UK women. Both South Asian and Caucasian women are at OP risk. This study compared experiences of osteoporotic Caucasian and South Asian women in a purposive sample of 21 volunteers from south east England, aged 43 to 82 years. The women had been diagnosed for eight months to 40 years. Long disease duration was marked by complacent OP dialogue, although OP was objectionable and marked a loss of quality of life. Inductive content analysis of transcripts showed that 'uncertainty'--about one another and about what constituted helpful self-care--affected both GPs and patients. Instead, support groups and the media supported learning about OP care. Beyond providing drug prescriptions, women reported desiring, but rarely feeling, that GPs fully supported their preferences for self-care. Self-care often included specialist exercise classes. Some younger women led their GPs to better understand the range of self-care options. GPs were seen as being unsure about how and when to discuss physical activity (PA). In conclusion, women with OP in this sample are sensitive to their GP's hesitance about offering detailed PA recommendations. Regardless of ethnicity, younger women undertook PA based on personal initiative. Positive PA experiences stimulated an interest in discussing PA with GPs, and these dialogues broke the silence surrounding OP care. By providing important information regarding the OP patient experience, the findings highlight the unmet desire of OP sufferers for better and closer attention from GPs.

BackgroundPolycystic ovary syndrome (PCOS) is the most common chronic endocrine disorder affecting women of reproductive age. This study aimed to compare the HRQoL of South Asian and white Caucasian women with PCOS, given that it is particularly common among women of South Asian origin and they have been shown to have more severe symptoms.MethodsThe Polycystic Ovary Syndrome Questionnaire (PCOSQ) and the Short Form-36 (SF-36) were administered in a cross-sectional survey to 42 South Asian and 129 Caucasian women diagnosed with PCOS recruited from the gynaecology outpatient clinics of two university teaching hospitals in Sheffield and Leeds. Additional clinical data was abstracted from medical notes. Normative data, collected as part of the Oxford Health and Lifestyles II survey, was obtained to compare SF-36 results with ethnically matched women from the general UK population. Using the SF-36, normative HRQoL scores for women of South Asian origin were lower than for Caucasian women. Given this lower baseline we tested whether the same relationship holds true among those with PCOS.ResultsAlthough HRQoL scores for women with PCOS were lower than normative data for both groups, South Asian women with PCOS did not have poorer HRQoL than their Caucasian counterparts. For both the SF-36 and PCOSQ, mean scores were broadly the same for both Asian and Caucasian women. For both groups, the worst two HRQoL domains as measured on the PCOSQ were 'infertility' and 'weight', with respective scores of 35.3 and 42.3 for Asian women with PCOS compared to 38.6 and 35.4 for Caucasian women with PCOS. The highest scoring domain for South Asian women with PCOS was 'menstrual problems' (55.3), indicating best health, and was the only statistically significant difference from Caucasian women (p = 0.01). On the SF-36, the lowest scoring domain was 'Energy & Vitality' for Caucasian women with PCOS, but this was significantly higher for Asian women with PCOS (p = 0.01). The best health status for both groups was 'physical functioning', although this was significantly lower for South Asian women with PCOS (p = 0.005). Interestingly, only two domains differed significantly from the normative data for the Asian women with PCOS, while seven domains were significantly different for the Caucasian women with PCOS compared to their normative counterparts.ConclusionsThe HRQoL differences that exist between South Asian and Caucasian women in the general population do not appear to be replicated amongst women with PCOS. PCOS reduces HRQoL to broadly similar levels, regardless of ethnicity and differences in the normative baseline HRQoL of these groups.

Improving access and quality for ethnic minority women— panel discussion

Epidemiologic evidence suggests that a full-term pregnancy may affect maternal risk of breast cancer later in life. The objective of this cross-sectional study was to compare circulating levels of maternal hormones affecting breast differentiation (human chorionic gonadotropin and prolactin) and proliferation [alpha-fetoprotein, insulin-like growth factor I (IGF-I), and estradiol] between women at a low to moderate risk (Asians and Hispanics), as compared with women at a high risk for breast cancer (Caucasians and African-Americans). Between May 2002 and December 2004, a total of 586 pregnant women were approached during a routine prenatal visit. Among them, 450 women (206 Caucasian, 126 Asian, 88 Hispanic, and 30 African-American) met the inclusion criteria and signed the informed consent. Only singleton pregnancies were considered. Blood samples were drawn during the second trimester of pregnancy. Laboratory analyses were done using the IMMULITE 2000 immunoassay system. Gestational age standardized mean levels of estradiol, IGF-I, and prolactin were significantly higher in Hispanic women compared with Caucasian women. Mean concentration of IGF-I was significantly higher in African-American women compared with Caucasian and Asian women. No significant differences in pregnancy hormone levels were observed between Caucasian and Asian (predominantly second-generation Chinese) women in this study. Irrespective of ethnicity, women who had their first pregnancy had substantially higher mean levels of alpha-fetoprotein, human chorionic gonadotropin, estradiol, and prolactin compared with women who previously had at least one full-term pregnancy. These data suggest that circulating pregnancy hormone levels may explain some of the ethnic differences in breast cancer risk.

Attitudes towards eating, weight and shape were examined in 479 Caucasian, Afro-Caribbean and Asian British women. The Asian women were found to have significantly more disordered eating attitudes than the Caucasian women, but no difference was found between the three groups in their concern with their body weight and shape. However, while in the Caucasian group disordered eating attitudes were significantly positively correlated with feelings of anxiety and depression, this was not true in the other two groups. Although the concerns of British Afro-Caribbean and Asian women are similar to those of the Caucasian women, there may be ethnic differences in the relationship between feelings about eating, weight and shape and mood.
