The relationship of reports of aches and joint pains to the menopausal transition: a longitudinal study.

UNLABELLED: OBJECTIVES Part I: To determine factors associated with reported joint symptoms across the menopausal transition. Part II: To investigate the relationship between symptom reporting and radiological arthritis in postmenopausal women. DESIGN Part I: The Melbourne Women's Mid-life Health Project, commenced in 1991, is a population-based prospective study of 438 Australian-born women, aged 45-55 years and menstruating at baseline; they were interviewed annually over 8 years. The retention rate was 88% (n = 387). Part II: After 12 years of follow-up, 257 (57%) women returned for assessment and 224 agreed to undergo X-rays of their hands and knees. METHODS Part I: Annual fasting blood collection, physical measurements, and interviews including questions about bothersome aches or stiff joints in the previous 2 weeks. A score for this symptom was calculated from the product of the severity and frequency data. These data were analyzed using random-effects time-series regression models. Part II: X-rays were scored for evidence of osteoarthritis using a validated scale, by two investigators who were blinded to questionnaire results. RESULTS Part I: 'Aches and stiff joints' were the most commonly reported symptom and reporting increased over time in the longitudinal study. Variables significantly associated with reporting bothersome aches and stiff joints were high body mass index (BMI) (p < 0.001), high negative mood (p < 0.01), not being employed (p < 0.001), and experiencing the menopausal transition (p < 0.05). A higher severity and frequency of this symptom were associated with BMI (p < 0.01), not being employed (p < 0.05) and high negative mood (p < 0.005). Part II: The relationship between radiological osteoarthritis and symptom reports approached statistical significance (p = 0.06). Knee osteoarthritis was significantly associated with symptom reports (p = 0.008) but not hand osteoarthritis (p = 0.2). CONCLUSION: Menopausal status, BMI, employment status and depressed mood were all associated with the experience of bothersome aches and stiff joints. Aches and stiff joints, common in postmenopausal women, are not necessarily indicative of radiological osteoarthritis.

Physician diagnosed arthritis, reported arthritis and radiological non-axial osteoarthritis.

OBJECTIVE: To determine the question that best predicts radiographic evidence of non-axial osteoarthritis (OA). DESIGN: The Melbourne Women's Mid-life Health Project (MWMHP), commenced in 1991, is a population-based prospective study of 438 Australian-born. Two hundred and fifty-seven (57%) women remained in longitudinal assessment in 2002 and 224 (87%) women agreed to undergo X-rays of their hands and knees between 2002 and 2003. METHODS: Annually participants were asked about aches and stiff joints and arthritis or rheumatism. In the eleventh year of follow-up X-rays were scored for evidence of OA using a validated scale, by two investigators who were blinded to questionnaire results. Information on hormone therapy use, physical activity, mood, smoking, body mass index (BMI) and age were obtained by both self-administered and face-to-face questionnaires. RESULTS: Patient reported physician diagnosed arthritis was the best predictor of radiological OA (ROA). The question had a specificity of 64%, a positive predictive value of 57% and a negative predictive value of 71%. Even the most reliable question about arthritis still had a relatively low specificity for radiologically diagnosed OA. Reporting symptoms were significantly more common in participants who were depressed, those who had a higher negative affect and those with a higher BMI. CONCLUSION: In large epidemiological studies where questionnaire assessment of OA is required, the greatest accuracy is achieved by asking about physician diagnosed arthritis. Concurrent application of a validated scale for mood is important.

Moderate alcohol consumption contributes to women's well-being through the menopausal transition.

OBJECTIVES: To examine the association of alcohol consumption with well-being in mid-aged Australian women, taking into account other lifestyle factors. METHODS: A prospective, observational study was carried out among 438 urban Australian women aged 45-55 years at baseline. They were assessed annually for 8 years using a questionnaire on health and lifestyle, including self-ratings of well-being and daily 'hassles'. Statistical analyses were performed using cluster and repeated measures analyses. RESULTS: About 80% of the women had consumed alcohol in the week preceding the interview. Alcohol intake was weakly associated with well-being overall (p = 0.094). Women who consumed alcohol at moderate levels had higher well-being scores than non-drinkers or heavy drinkers, however, provided they were also non-smokers and exercised weekly or more (p for interaction = 0.023) (21% of all study participants). Everyday symptoms and stresses had a negative impact on well-being (all p values < 0.001). CONCLUSIONS: Among women undergoing menopausal transition, well-being is positively associated with moderate alcohol consumption along with other lifestyle factors in a synergistic fashion, rather than any individual factor having a dominant or an independent effect.

A prospective study of outcomes after hysterectomy in mid-aged Australian-born women.

OBJECTIVE: To describe the prevalence of hysterectomy in a mid-aged population-based sample of Australian-born women who were menstruating at baseline and followed for 11 years, and to compare the hysterectomized women with the non-hysterectomized women with regard to symptom reporting and health outcomes. METHODS: This was a 12-year prospective observational study of 438 women who at baseline were aged 45-55 years, not taking hormone therapy (HT) and had menstruated in the previous 3 months. Interviews were conducted face-to-face. RESULTS: After 11 years of follow-up, 39 (9%) women had experienced a hysterectomy, of whom 43.5% had the uterus only removed, 13% had the uterus plus one ovary and 43.5% had the uterus and both ovaries removed. Hysterectomies were performed on average 5.8 years prior to the year 11 interview. The mean age at hysterectomy was 54 years. Multivariate logistic regression analysis, including all co-variates, found that women who had experienced a hysterectomy (+/-oophorectomy) were significantly more likely to complain of trouble sleeping (p < 0.01), have problems with urine control (p < 0.05) and with their bowels (p = 0.07), have used HT (p < 0.05) and have a higher body mass index (p < 0.05). There were no significant associations between hysterectomy and sexuality or hot flush reporting. CONCLUSION: In a community-based sample of Australian-born women, the experience of a hysterectomy after the age of 45 years was associated with bladder, weight and sleeping problems 5-6 years after the surgery.

Intimate partner violence and health outcomes in mid-life women: a population-based cohort study.

AIM: To investigate the association between experience of intimate partner violence (IPV) and health outcomes measured prospectively. METHOD: Eleven-year prospective study of a population-based cohort of 438 Australian-born women aged 45-55 years at baseline (in 1991). Annual face-to-face interviews measured health status and quality of life; questionnaires on intimate partner physical, emotional and sexual violence and on experiences of childhood abuse completed in year 6 of follow-up. RESULTS: In year 11 of follow-up 233 women (mean age 59.9 SD 2.5 years) were interviewed of whom 62 (27%) reported experiencing physical and/or emotional and/or sexual IPV prior to the 6(th) year of follow-up. In bi-variate analysis a history of IPV was significantly associated with mental and sexual health variables and marital status at baseline and follow-up. Multivariate analysis found that at follow-up after allowing for baseline measures and other co-variates: Frequency of Sexual Activities was lower in women who had experienced IPV (p < 0.05); and negative mood was higher in women with the experience of IPV during the 12 months prior to completing the violence questionnaire (p < 0.05). CONCLUSION: IPV was a significant contributor to mental and sexual health status measured prospectively in this cohort of mid-aged Australian-born women.

Factors affecting the prevalence of osteoarthritis in healthy middle-aged women: data from the longitudinal Melbourne Women's Midlife Health Project.

The prevalence of osteoarthritis (OA) is greater in women then men. Weight, a factor strongly associated with osteoarthritis, is significantly increased over the menopausal transition. Despite the high prevalence of osteoarthritis, a disabling disease with limited treatment options, there is a paucity of studies in women. The longitudinal phase of the Melbourne Women's Midlife Health Project, is a population-based prospective study of 438 Australian born women who have been followed annually over 11 years. 257 (59%) of these women remained in longitudinal assessment at 11th year of follow-up and 224 of these women agreed to undergo X-rays of their knees and hands. In this study, X-rays were scored for evidence of osteoarthritis using a validated scale, by two investigators who were blinded to questionnaire results. Information on hormone therapy use, physical activity, smoking, BMI and age were obtained by both self-administered and face-to-face questionnaires. Results showed that one hundred and twenty-eight women (56%) had evidence of radiological OA. Forty-nine (21.6%) had evidence of radiological knee OA. One hundred and one (44.5%) had evidence of radiological hand OA. Compared to baseline, at 11th year of follow-up participants had put on weight (4 kg range -14 to 25 kg) and a larger proportion (25% vs. 40%) reported exercising frequently (P = 0.005). Physical activity and BMI were associated with higher prevalence of osteoarthritis in the final year of follow-up. Smoking was associated with a lower prevalence of radiological knee OA. The prevalence was 61% among never smokers compared to only 39% among those who smoked (P < 0.05). Total OA was associated with never having used hormone therapy (odds ratio 2.7; CI 1.1-6.9). There was a trend for increasing level of physical activity at ages 20-29 to be associated with an increased risk of knee OA (P value 0.03 for trend). In conclusion increasing age, BMI and history of more frequent physical activity in younger years were risk factors for radiological knee OA. In contrast, smoking appeared to be associated with less knee OA. Never having used hormone therapy was a risk factor for radiological hand and knee OA. Further work will be needed to determine whether modification of these factors can prevent the development of OA.

Serum C-reactive protein and plasma homocysteine levels are associated with hormone therapy use and other factors: a population-based study of middle-aged Australian-born women.

OBJECTIVE: To investigate the associations between C-reactive protein (CRP), homocysteine levels, use of hormone therapy (HT) and other factors. METHODS: A 12-year prospective study of 438 Australian-born women (Melbourne Women's Midlife Health Project), who at baseline were aged 45-55 years, had menstruated in the previous 3 months and were not taking HT. Fasting blood was collected in the 11th follow-up year for CRP, homocysteine, estradiol and follicle stimulating hormone (FSH) levels. Physical measurements and face-to-face interviews obtained information on health and lifestyle variables. RESULTS: A total of 258 women (mean age 60 years) participated in the 11th follow-up year. Multiple regression analysis found that CRP levels were positively associated with body mass index (p < 0.001), HT use (p < 0.01), and negatively associated with statin use (p < 0.005) and exercising (p < 0.05). In postmenopausal women currently not using HT (n = 173) and after adjusting for body mass index, exercise and smoking, CRP was negatively associated with FSH levels (beta = -0.32, p < 0.05). Homocysteine levels were positively associated with smoking (p < 0.001) and negatively associated with HT use (p < 0.05). CONCLUSION: In middle-aged Australian-born women, HT use was associated with increased CRP and decreased homocysteine levels. High CRP levels were also associated with high relative weight, low exercise levels and no statin medication.

The menopausal transition: does it induce women's worries about aging?

OBJECTIVE: This study examines whether patterns of worries about aging change in women during the menopausal transition. DESIGN: A population-based sample of 261 Australian-born women aged 45-55 years at baseline participated in a longitudinal study. Data were collected at baseline and in the 5th year of annual follow-up interviews. Measures included the Attitudes to Aging Scale which is based on a scale developed by Kaufert and Syrotuik and contained the six-item version which examines worries about specific losses. Menopausal status was determined by menstrual status as follows: late reproductive, early menopausal transition, late menopausal transition, and postmenopause. RESULTS: Data analysis carried out by cross-tabulation found that 36% of participants did not change their attitudes over the 5-year follow-up period, 30% became more worried and 33% became less worried and there was no significant difference between those who had or had not experienced the menopausal transition. There was no significant association between the scores on the Attitudes to Aging Scale and changes in the self-rated health, work status and marital status. CONCLUSION: The menopausal transition does not induce an overall increase in worries about aging.

The menopausal transition: a 9-year prospective population-based study. The Melbourne Women's Midlife Health Project.

OBJECTIVES: To describe the natural history of the menopause in Australian-born women. To determine the hormonal changes relating to the menopausal transition (MT) and how these affect quality of life, bone mineral density, body composition, cardiovascular disease (CVD) risk and memory. DESIGN: A 9-year prospective, observational study of a population-based sample of 438 Australian-born women aged 45-55 years at baseline. By the 9th year, the retention rate was 88%. Interviews, blood sampling, menstrual calendars, quality of life and physical measures were taken annually, and bone mineral density was measured bi-annually. RESULTS: The late MT coincides with changes in estradiol, follicle stimulating hormone, and free testosterone index, decreases in bone density and mastalgia, and increases in central adiposity, vasomotor symptoms, insomnia and vaginal dryness. Levels of total testosterone and dehydroepiandrosterone sulfate are unchanged by the MT. An increase in CVD risk was associated with increases in weight and free testosterone index and a decrease in estradiol. Depressed mood is increased by symptoms and by stressors occurring in the MT. Sexual functioning significantly deteriorates with the MT and aging, but relational factors have major effects. Menstrual cycles became more variable and longer closer to the final menstrual period. CONCLUSIONS: As hormonal changes during the MT directly or indirectly adversely affect quality of life, body composition and CVD risk, maintenance of health parameters in the premenopausal years is crucial for a healthy postmenopause.

Serum lipids and memory in a population based cohort of middle age women.

OBJECTIVE: To assess the relation between serum lipids and memory in a healthy middle age cohort of women. METHODS: For 326 women in the Melbourne Women's Midlife Health Project aged 52-63 years, serum lipids were measured annually, and memory was assessed during the eighth annual visit. RESULTS: There was a small but significant association between current low density lipoprotein cholesterol (LDL-C) concentrations and memory; for total cholesterol (TC) the association approached significance. Better memory was associated with positive changes in TC and LDL-C based on lipid measurements three years, but not six years, earlier. Memory performance was lowest among women in the lowest quartile of current LDL-C values and among women whose LDL-C levels declined over the previous three years. High density lipoprotein cholesterol (HDL-C) and triglyceride concentrations were unassociated with memory. The association between memory and TC and LDL-C was primarily related to immediate recall and not delayed recall performance on the word list task. Low cholesterol has been linked with depression, but lipid measures and self-rated mood were unrelated. CONCLUSIONS: Higher serum concentrations of LDL-C, and relatively recent increases in TC and LDL-C concentrations, are associated with better memory in healthy middle age women. Possible cognitive effects of cholesterol reduction should be considered in future studies of lipid lowering agents.

Health care-seeking for menopausal problems.

OBJECTIVES: To determine the rate and timing of medical consultations for menopausal problems during the menopausal transition and to identify baseline and prospective variables associated with these consultations. METHODS: This was a 9-year community-based study with annual interviews of 438 Australian-born women who at baseline were aged 45-55 years, had menstruated in the previous 3 months and were not using hormone therapy. RESULTS: In total, 387 women completed the 9-year study, of whom 86% consulted a doctor about menopausal problems, with an annual mean of 31%. Of the women, 212 experienced a natural menopause. The prevalence of consultations regarding menopausal problems was a maximum about 2.5 years before the final menstrual period (FMP). The time of greatest prevalence of reporting bothersome hot flushes was 2.1 years after the FMP. There was no significant relationship between number of symptoms reported and time to/from the FMP. Multiple regression analysis found that an increased number of consultations for menopausal problems was associated with the baseline variables: vasomotor symptoms (p < 0.005), rating one's health as 'worse than most' (p < 0.005) and taking two or more non-prescription medications (p < 0.05); and the follow-up variables: dysphoric symptoms (p < 0.05), vasomotor symptoms (p < 0.005) and hormone therapy use (p < 0.001). CONCLUSION: Nearly one-third of women will consult a doctor annually during the years of the menopausal transition. Those who are more symptomatic with mood or vasomotor symptoms consult doctors more often and are more likely to use hormone replacement therapy.

Estrogen exposures and memory at midlife: a population-based study of women.

Estrogen loss after natural menopause is hypothesized to impair episodic memory. A total of 326 women aged 52 to 63 years participating in the Melbourne Women's Midlife Health Project completed a word list memory task. Estrogen exposures were inferred from menopausal status, time from final menstrual period, use of hormone therapy, serum estradiol concentration, and other indices. Memory did not vary significantly with most exposures. The authors conclude that episodic verbal memory assessed by word list learning is not substantially affected during the menopausal transition or in the years immediately after natural menopause.

Studying the menopausal transition: methodological considerations.

OBJECTIVE: To document prospectively the menopausal status of a population-based cohort of women. METHODS: A 11-year community-based study with annual interviews of 438 Australian-born women who at baseline were aged 45-55 years, had menstruated in the previous 3 months and were not using hormone therapy or the oral contraceptive pill. Women were interviewed annually in their own homes. Each woman's menstrual history during her transition to menopause was documented prospectively using menstrual calendars. RESULTS: After 11 years of follow-up, the retention rate was 83%. The percentages of the cohort who had experienced a natural menopause at the 3rd, 6th, 9th and 11th years of follow-up were 13%, 36%, 51% and 52%, respectively. After 11 years of follow-up, 3% of the cohort had menstruated in the previous 12 months and 18% had used hormone therapy prior to their final menstrual period. CONCLUSION: In studying the normal transition to menopause, the baseline age of the cohort, the length of time available for follow-up, the intervention rate (hormone therapy and hysterectomy) and the number of participants all need to be considered to ensure there is sufficient power for analyses.

Is incontinence associated with menopause?

OBJECTIVES: To estimate (1) the prevalence of urinary incontinence in a population-based sample of Australian women aged 45-55 and to identify the factors associated with urinary incontinence; (2) the incidence of urinary incontinence over a 7-year follow-up period and to identify whether the transition from pre- to postmenopause is associated with the development of urinary incontinence. METHODS: This was a cross-sectional study of 1897 women and a 7-year longitudinal follow-up of 373 of these women who were premenopausal at baseline. Annual interviews and physical measurements were taken in their homes. RESULTS: Cross-sectional: the prevalence of urinary incontinence was 15%; multivariate analysis found that urinary incontinence patients were significantly more likely than those without incontinence to have higher body mass index (odds ratio [OR] 1.50, 95% confidence interval [CI] 1.15, 1.95), have had gynecologic surgery (OR 2.17, 95% CI 1.42, 3.32), report urinary tract infections (OR 4.75, 95% CI 2.28, 9.90), diarrhea or constipation (OR 1.95, 95% CI 1.27, 3.00), and have had three or more children (OR 1.47, 95% CI 1.06, 2.05). Longitudinal: during the 7-year follow-up, the average prevalence of urinary incontinence was 18% and the overall incidence 35%. Women who experienced a hysterectomy during the follow-up period had a higher incidence. CONCLUSION: Urinary incontinence in middle-aged women is more closely associated with mechanical factors than with menopausal transition.

Impaired fasting glycaemia in middle-aged women: a prospective study.

OBJECTIVES: To investigate: (i) the incidence of impaired fasting glycaemia (IFG) developed over 5 y in a population-based sample of Australian-born women; (ii) prospectively the factors which are associated with the development of IFG; (iii) the association of the menopausal transition with the onset of IFG and an increase in serum insulin concentrations. DESIGN AND METHODS: A total of 265 women (110 pre-, 138 peri-, 17 postmenopausal) participants in the longitudinal phase of the Melbourne Women's Midlife Health Project, aged 46-57 and with normal fasting plasma glucose concentrations at the time of the initial measure, were interviewed, had physical measurements and blood taken annually over a 5 y follow-up period. RESULTS: During the study period 43 women (16%) recorded a fasting glucose concentration of > or =6.1 mmol/l (IFG). Women who recorded IFG prospectively had, at the time of the initial measure when fasting glucose concentrations were normal: higher body mass index (BMI), trunk skinfold thicknesses, waist and hip circumferences (P<0.005), lower SHBG, higher free androgen index and serum insulin concentrations (P<0.05), higher systolic blood pressure, serum triglyceride and lower HDL-cholesterol concentrations (P<0.05) than women whose fasting glucose concentrations remained normal. The onset of IFG was not triggered by the menopausal transition or hormone use. Changes in insulin concentration were associated with changes in BMI (P<0.05). CONCLUSION: Women who developed IFG during the menopausal transition exhibited significantly higher levels of body fatness and dyslipidemia, premenopausally, compared with the women who did not develop IFG. The menopausal transition did not have an effect on the development of IFG, but weight gain during this period was associated with an increase in insulin concentration.

Attitudes of middle-aged women to aging: contribution of the Reactions to Aging Questionnaire.

Attitudes to aging in mid-life have been found to be a predictor of health and well-being. The main purpose of the study was to assess the contribution of the Reactions to Aging Questionnaire (RAQ) to the understanding of middle-aged women's attitudes towards their aging. An additional purpose was to expand the existing information regarding the dimensions of the new version of the RAQ. Middle-aged Melbourne women (n = 381) were asked to complete the RAQ, in addition to another attitudes-to-aging scale (Worries About Aging). Factor analysis of the RAQ was used to explore its dimensionality, and frequencies of responses were used to assess the spread of response of both instruments. The factors extracted in the factor analysis of the RAQ were interpretable and meaningful in terms of emotions related to aging. They were also similar to the factors described by previous data. The RAQ was more effective in its distribution ability than the Worries About Aging Scale. With some modifications, the RAQ may be more informative than was the Worries About Aging Scale in its ability to assess emotions, opinions and beliefs associated with aging in middle-aged women.

Risk factors for osteoporosis: A review.

Skeletal fragility and falls are the 2 most potent factors leading to osteoporotic fractures. The aim of this article is to review factors associated with women's risk of developing skeletal fragility and subsequent osteoporosis. Many factors have been implicated, but the evidence for some is unsubstantial. Low premenopausal bone mineral density (BMD), a decrease in BMD, and an increase in bone fragility -- which occur as a result of both aging and the menopause -- are major determinants of subsequent risk for osteoporotic fracture. In addition, low body mass index (BMI), low calcium intake, low physical activity, and smoking can affect BMD. The relative importance of the effects these physical and lifestyle factors have on BMD in midlife women is not fully established. The impact of gynecologic history (parity, lactation, oral contraceptive use, age of menarche) on BMD is uncertain.

Risk factors for osteoporosis: prevalence, change, and association with bone density.

OBJECTIVES: To describe the prevalence of risk factors for osteoporosis in a population-based cohort of Australian-born midlife women; determine the effect of these risk factors on premenopausal and early perimenopausal bone mineral density (BMD); and describe changes in risk factors and any effect of these on bone loss. DESIGN: 4-year longitudinal community-based study. BMD of the lumbar spine (LS) and femoral neck (FN) was measured using dual x-ray absorptiometry (DXA). SETTING: Melbourne, Australia PARTICIPANTS: 224 Australian-born women aged 46-56 years MAIN OUTCOME MEASURES: Risk factors for osteoporosis, LS-BMD, FN-BMD, and change in risk factors and BMD. RESULTS: At baseline, 52% reported a calcium intake of less than 800 mg/day and 46% reported a caffeine intake of more than 360 mg/day; 29% exercised less than 1.5 hours/week; 5% had a body mass index (BMI) of less than 20; 14% were current smokers; 23% were past smokers; 10% reported abnormal menstrual histories; and 25% reported a family history of osteoporosis. BMD was positively associated with weight; BMI; and waist, hip, and trunk skin-fold measure (P less than .0005). At 4-year follow-up, there were increases in weight (P less than .0005), waist/hip ratio (P less than. 05), trunk skin-fold measurements (P less than.005), and calcium intake (P less than.05). In women who became late perimenopausal or postmenopausal, bone loss was associated with time in relation to the final menstrual period but not with other variables. CONCLUSIONS: There are multiple risk factors for osteoporosis in this Australian-born population of midlife women, but only anthropometric variables were associated with BMD at baseline. Significant changes during the menopausal transition in anthropometric variables and calcium intake were in the direction that could decrease the risk of osteoporosis but were not found to affect menopausal bone loss.

A prospective population-based study of menopausal symptoms.

OBJECTIVE: To identify symptoms that change in prevalence and severity during midlife and evaluate their relationships to menopausal status, hormonal levels, and other factors. METHODS: In a longitudinal, population-based study of 438 Australian-born women observed for 7 years with an 89% retention rate, 172 advanced from premenopause to perimenopause or postmenopause. Annual measures included a 33-item symptom check list; psychosocial, lifestyle, and health-related factors; menstrual status; hormone usage; and blood levels of follicle-stimulating hormone and estradiol (E2). RESULTS: Increasing from early to late perimenopause were the number of women who reported five or more symptoms (+14%), hot flushes (+27%), night sweats (+17%) and vaginal dryness (+17%) (all P <.05). Breast soreness-tenderness decreased with the menopausal transition (-21%). Trouble sleeping increased by +6%. The major change in prevalence was from early to late perimenopause, except for insomnia, which showed a gradual increase. Those variables most related to onset of hot flushes were number of symptoms at early perimenopause (P <.05), having an unskilled or no occupation (P <.05), more than 10 pack-years of smoking (P <.01), and decreased E2 (P <.01). The onset of night sweats increased with the change in E2 (P <.05). The onset of vaginal dryness decreased with more years of education (P <.05). Trouble sleeping was predicted by prior lower well-being (P <.01), belief at baseline that women with many interests hardly notice menopause (P <.01), and hot flushes (P <.01). CONCLUSION: Although middle-aged women are highly symptomatic, the symptoms that appear to be specifically related to hormonal changes of menopausal transition are vasomotor symptoms, vaginal dryness, and breast tenderness. Insomnia reflected bothersome hot flushes and psychosocial factors.

Longitudinal study of risk factors for coronary heart disease across the menopausal transition.

The patterns of change in blood lipids, diastolic blood pressure, body mass index, smoking and drinking behaviors, and exercise were examined in an ongoing longitudinal study from 1991 to 1995 of 150 middle-aged Melbourne, Australia, women as they passed through menopause. Changes in risk factors over time were examined with reference to time of the final menstrual period (FMP). Random effects models were fitted with adjustments for repeated measures and other covariates, including age. There were overall net increases between 3 years before and the 3 years after menopause of 0.25 mmol/liter for low density lipoprotein cholesterol, 0.05 mmol/liter for high density lipoprotein cholesterol (HDL cholesterol), 0.34 mmol/liter for triglycerides, 0.12 kg/m2 for body mass index, and 0.48 mmHg for diastolic pressure. The proportion of drinkers decreased by 13%, that of smokers increased by 17%, and that of women who exercised at least once a week increased by 6%. The only change dependent on the FMP was a significant decrease in HDL cholesterol (counterbalanced by a similar rise in HDL cholesterol in the year before the FMP), and the rate of decrease was maximal around 9 months after menses ceased, with an instantaneous estimate of slope of 0.55 mmol/liter per year.
