Abstract
OBJECTIVE The aim of this study was to determine the prevalence and associated factors of mild cognitive impairment (MCI) and subtypes, amnestic MCI (aMCI) and non-amnestic MCI (naMCI), in women with surgical menopause. METHODS We obtained the database containing information for 200 women with surgical menopause from our previous study. The Montreal Cognitive Assessment - total score, the Montreal Cognitive Assessment - memory index score (MoCA-MIS) and their age, years since menopause, education, medical and surgical history, hormone therapy use, exercise, sleep duration, alcohol use, smoking and family history of dementia were obtained. All participants without the MoCA-MIS were excluded. RESULT The average age of the 164 participants was 56.3 ± 6.9 years. The prevalence of MCI, aMCI and naMCI was 43.3%, 9.8% and 33.5%, respectively. The duration of education reduced MCI for 93% (95% confidence interval 0.03-0.20) of the women. In late postmenopause, hormone therapy >10 years showed 47% lower prevalence of MCI (age-adjusted odds ratio = 0.53, 95% confidence interval 0.22-1.28). Finally, length of education was the only independent factor associated with MCI and its subtypes. CONCLUSION We found a high prevalence of MCI and the non-amnestic subtype in women with surgical menopause. Further study is needed to clarify the long-term effects of surgical menopause on cognitive function.

Abstract
OBJECTIVE This study aims to explore the prevalence of decreased frontal lobe function and its associated factors in women with surgical menopause. METHODS This study is a retrospective analysis of a cross-sectional study conducted between October 2013 and July 2014. Data from 164 women with surgical menopause were analyzed. The Montreal Cognitive Assessment Thai version (MoCA-T) test was administered by a psychologist. The MoCA frontal lobe function score was derived from visuospatial/executive, abstraction, attention, and verbal fluency tests. Multivariable logistic regression was used to assess data associated with decreased frontal lobe function. RESULTS The mean age of participants was 56.3 ± 6.9 years, and the mean time since menopause was 11.3 ± 7.4 years. The prevalence of decreased frontal lobe function score was 73.8%, with an average score of 6.21 ± 1.84. The independent factor associated with a lower MoCA frontal lobe function score was duration of education greater than 6 years. CONCLUSION Our study adds information about decreased frontal lobe function in almost three-quarters of women with surgical menopause. Duration of education greater than 6 years was a protective factor. Menopause hormone therapy usage did not seem to increase the detrimental effect on frontal lobe function when initiated in young women with surgical menopause.

Abstract
The adjusted incidence rate of hip fracture in Thailand has increased more than 31% from 1997 to 2006. Mortality and morbidity after hip fracture are also high. One year mortality after a hip fracture has increased from 18% in 1999 to 21% in 2007. The Thai Osteoporosis Foundation (TOPF) developed the first Clinical Practice Guideline (CPG) in 2002 and keeps updating the CPG since then. This latest version of the CPG is our attempt to provide comprehensive positional statement on the diagnosis, prevention and treatment of osteoporosis in Thailand. The study group who revised this position statement contains experts from the TOPF, Four Royal Colleges of Thailand, includes the Orthopaedic Surgeons, Gynecologists and Obstetricians, Physiatrists, Radiologists and 2 Associations of Endocrinologists and Rheumatologists which have involved in the management of patients with osteoporosis.

Abstract
OBJECTIVES The primary objective of this study was to evaluate the correlation among symptoms, signs, and the number of lactobacilli in postmenopausal vaginal atrophy. The secondary objective was to develop a new parameter to improve the correlation. STUDY DESIGN A cross-sectional descriptive study. METHODS Naturally postmenopausal women aged 45-70 years with at least one clinical symptom of vaginal atrophy of moderate to severe intensity were included in this study. All of the objective parameters (vaginal atrophy score, vaginal pH, the number of lactobacilli, vaginal maturation index, and vaginal maturation value) were evaluated and correlated with vaginal atrophy symptoms. A new parameter of vaginal atrophy, vaginal atrophy symptoms II, was developed and consists of the two most bothersome symptoms (vaginal dryness and dyspareunia). Vaginal atrophy symptoms II was analyzed for correlation with the objective parameters. RESULTS A total of 132 naturally postmenopausal women were recruited for analysis. Vaginal pH was the only objective parameter found to have a weak correlation with vaginal atrophy symptoms (r = 0.273, p = 0.002). The newly developed vaginal atrophy symptoms II parameter showed moderate correlation with vaginal pH (r = 0.356, p < 0.001) and a weak correlation with the vaginal atrophy score (r = 0.230, p < 0.001). History of sexual intercourse within 3 months was associated with a better correlation between vaginal atrophy symptoms and the objective parameters. CONCLUSION Vaginal pH was significantly correlated with vaginal atrophy symptoms. The newly developed vaginal atrophy symptoms II was associated with a better correlation. The vaginal atrophy symptoms II and vaginal pH may be better tools for clinical evaluation and future study of the vaginal ecosystem.

Abstract
OBJECTIVE To determine the effects of estrogen therapy on objective sleep quality in insomniac postmenopausal women without severe vasomotor symptoms and/or recognized hot flushes during sleep. Study design Randomized, double-blinded, placebo-controlled trial, parallel design (ClinicalTrials.gov Identifier: NCT01501422). METHODS Forty insomniac postmenopausal women with no severe vasomotor symptoms and/or recognized hot flushes during sleep were randomized into 2 months' treatment with a 50-μg transdermal estradiol patch or placebo. Sleep quality was determined objectively with wrist actigraphy. Sleep efficiency, total sleep time, wake up after sleep onset and number of awakenings were compared before and after treatment. The Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) questionnaires were used for subjective sleep quality assessment before and after treatment. RESULTS The study showed no significant difference in sleep efficiency improvement between women having estrogen alone or placebo (median 85.7% vs. 85.2%, respectively, p = 0.71). Similarly, sleep quality scores assessed by ISI and ESS were not significantly different. CONCLUSION Estrogen therapy in insomniac postmenopausal women without severe vasomotor symptoms and/or recognized hot flushes during sleep was not found to improve sleep efficiency during the study period.

Abstract
Objective The aim of this study was to demonstrate the efficacy of an ultra-low-dose vaginal estriol 0.03 mg in combination with viable Lactobacillus acidophilus KS400 (Gynoflor® vaginal tablets) in the short-term therapy and to investigate the long-term maintenance dose in the treatment of vaginal atrophy. Methods This was a double-blind, randomized, placebo-controlled study (Controlled phase – initial therapy) followed by an open-label follow-up (Open phase – test medication initial and maintenance therapy). Included were postmenopausal women with vaginal atrophy symptoms and Vaginal Maturation Index (VMI) of ≤ 40%. The method of treatment was initial therapy with test medication (or placebo in first phase), one vaginal tablet daily for 12 days, followed by maintenance therapy, one tablet on two consecutive days weekly for 12 weeks. Results A total of 87 women completed the study. The Controlled phase results for a change in VMI demonstrated superiority of the 0.03 mg estriol–lactobacilli combination to placebo (p < 0.001). In the test group, the positive change in VMI was 35.2%, compared to 9.9% in the placebo group. In the Open phase after the initial therapy, the VMI was increased to 55.4% and, during maintenance therapy, it stayed at a comparable level (52.8–49.4%). The maturation of epithelium was followed by improvement of clinical symptoms and normalization of the vaginal ecosystem. Conclusions The ultra-low-dose, vaginal 0.03 mg estriol–lactobacilli combination (Gynoflor®) was superior to placebo with respect to changes in VMI after the 12-day initial therapy, and the maintenance therapy of two tablets weekly was sufficient to prevent the relapse of vaginal atrophy.

Abstract
BACKGROUND Pathophysiologic changes during the menopause transition may contribute to the risk of metabolic syndrome (MetS). Body fat composition, particularly visceral fat, is highly associated with increased insulin resistance, abnormal carbohydrate metabolism and high blood pressure. We purposefully wished to determine the optimal cut-off values of body fat composition, including visceral fat, in order to predict MetS and to assess the prevalence of MetS in peri- and postmenopausal women. METHODS This cross-sectional study was conducted in a population-based, prospective cohort at the Menopause and Gynecology clinics, King Chulalongkorn Memorial Hospital. Body fat percentage and visceral fat rating were measured by a bioelectrical impedance analyzer (Tanita SC 330). MetS was diagnosed using the Harmonizing criteria of A Joint Interim Statement of IDF/NHLBI/AHA/WHF/IAS/IASO 2009. Receiver operating characteristic analyses were performed to determine the optimal cut-off values of body fat, visceral fat, waist circumference and body mass index to identify peri- and postmenopausal women at risk of MetS. RESULTS Ninety-two perimenopausal and 446 postmenopausal women aged 40-60 years were recruited for the analyses. The optimal cut-off values for body fat percentage, visceral fat rating, waist circumference and body mass index for identifying women at risk of MetS were 34%, 7, 88 cm and 24 kg/m(2), respectively. The prevalence of MetS in this study was 27.9%. CONCLUSION The optimal cut-off values to predict MetS of body fat percentage, visceral fat and waist circumference were established. Using the Harmonizing 2009 criteria, we found that approximately one out of four peri- and postmenopausal women in this study had MetS.

Abstract
OBJECTIVES To develop a new instrument, the Menopause-specific Quality of Life Scale (MS-QoLS), for Thai women and to study the experience of menopausal aspects in peri- and postmenopausal Thai women. MATERIALS AND METHODS Item generation was developed from a focus group discussion and in-depth interview, and the content validity index (CVI) was computed, using item relevance ratings by content experts. Items with CVI values higher than 0.7 were selected. The draft questionnaire was tested for language, format and content. The final questionnaire was administered and the construct validity and reliability were then assessed. RESULTS Fifty-seven peri- and postmenopausal women participated in the focus group discussion and in-depth interview. Sixty-eight items across eight dimensions were generated based on content analysis result. The dimensions included Physical health, Psychological health, Sexual health, Daily activity, Family, Social, Treatment, and Economics. A total of 280 menopausal women were recruited from four collaborative hospitals for psychometric validation. After factor analysis, 22 items remained with six dimensions identified, that is, well-being, emotionality, anxiety/fear, family, social and sexual health. Cronbach's coefficient α of each domain was between 0.61 and 0.83. CONCLUSION The Thai MS-QoLS was systematically developed and validated for peri- or postmenopausal women. The initial assessment of the questionnaire showed an acceptable level of validity and reliability.

Abstract
In the Phase III PATRICIA study (NCT00122681), the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine (Cervarix(®), GlaxoSmithKline Biologicals) was highly efficacious against HPV-16/18 infections and precancerous lesions in women HPV-16/18 deoxyribose nucleic acid (DNA) negative and seronegative at baseline. We present further data on vaccine efficacy (VE) against HPV-16/18 in the total vaccinated cohort including women who may have been exposed to HPV-16/18 infection before vaccination. In women with no evidence of current or previous HPV-16/18 infection (DNA negative and seronegative), VE was 90.3% (96.1% confidence interval: 87.3-92.6) against 6-month persistent infection (PI), 91.9% (84.6-96.2) against cervical intraepithelial neoplasia (CIN)1+ and 94.6% (86.3-98.4) against CIN2+ [97.7% (91.1-99.8) when using the HPV type assignment algorithm (TAA)]. In women HPV-16/18 DNA negative but with serological evidence of previous HPV-16/18 infection (seropositive), VE was 72.3% (53.0-84.5) against 6-month PI, 67.2% (10.9-89.9) against CIN1+, and 68.8% (-28.3-95.0) against CIN2+ [88.5% (10.8-99.8) when using TAA]. In women with no evidence of current HPV-16/18 infection (DNA negative), regardless of their baseline HPV-16/18 serological status, VE was 88.7% (85.7-91.1) against 6-month PI, 89.1% (81.6-94.0) against CIN1+ and 92.4% (84.0-97.0) against CIN2+ [97.0% (90.6-99.5) when using TAA]. In women who were DNA positive for one vaccine type, the vaccine was efficacious against the other vaccine type. The vaccine did not impact the outcome of HPV-16/18 infections present at the time of vaccination. Vaccination was generally well tolerated regardless of the woman's HPV-16/18 DNA or serological status at entry.

Abstract
BACKGROUND The human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine was immunogenic, generally well tolerated, and effective against HPV-16 or HPV-18 infections, and associated precancerous lesions in an event-triggered interim analysis of the phase III randomised, double-blind, controlled PApilloma TRIal against Cancer In young Adults (PATRICIA). We now assess the vaccine efficacy in the final event-driven analysis. METHODS Women (15-25 years) were vaccinated at months 0, 1, and 6. Analyses were done in the according-to-protocol cohort for efficacy (ATP-E; vaccine, n=8093; control, n=8069), total vaccinated cohort (TVC, included all women receiving at least one vaccine dose, regardless of their baseline HPV status; represents the general population, including those who are sexually active; vaccine, n=9319; control, n=9325), and TVC-naive (no evidence of oncogenic HPV infection at baseline; represents women before sexual debut; vaccine, n=5822; control, n=5819). The primary endpoint was to assess vaccine efficacy against cervical intraepithelial neoplasia 2+ (CIN2+) that was associated with HPV-16 or HPV-18 in women who were seronegative at baseline, and DNA negative at baseline and month 6 for the corresponding type (ATP-E). This trial is registered with ClinicalTrials.gov, number NCT00122681. FINDINGS Mean follow-up was 34.9 months (SD 6.4) after the third dose. Vaccine efficacy against CIN2+ associated with HPV-16/18 was 92.9% (96.1% CI 79.9-98.3) in the primary analysis and 98.1% (88.4-100) in an analysis in which probable causality to HPV type was assigned in lesions infected with multiple oncogenic types (ATP-E cohort). Vaccine efficacy against CIN2+ irrespective of HPV DNA in lesions was 30.4% (16.4-42.1) in the TVC and 70.2% (54.7-80.9) in the TVC-naive. Corresponding values against CIN3+ were 33.4% (9.1-51.5) in the TVC and 87.0% (54.9-97.7) in the TVC-naive. Vaccine efficacy against CIN2+ associated with 12 non-vaccine oncogenic types was 54.0% (34.0-68.4; ATP-E). Individual cross-protection against CIN2+ associated with HPV-31, HPV-33, and HPV-45 was seen in the TVC. INTERPRETATION The HPV-16/18 AS04-adjuvanted vaccine showed high efficacy against CIN2+ associated with HPV-16/18 and non-vaccine oncogenic HPV types and substantial overall effect in cohorts that are relevant to universal mass vaccination and catch-up programmes.

Abstract
OBJECTIVES Significant differences in the prevalence of menopausal symptoms and in lipid profiles have previously been reported for nine ethnic groups of postmenopausal Asian women participating in the Pan-Asia Menopause (PAM) study. Based on these findings, we tested the hypothesis that reproductive hormone profiles differ among the nine ethnic groups under investigation in the PAM study. METHODS Baseline serum samples from postmenopausal women (n=1020) representing nine ethnic groups were analyzed at a central laboratory by electro-chemiluminescence immunoassay methods. Hormone concentrations were measured for estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH). RESULTS The hormone levels for the overall study population (mean+/-SD) were: E2=74.1+/-125.1 pmol/l (n=1015); FSH=81.2+/-31.4 IU/l (n=1013); LH=36.8+/-15.6 IU/l (n=1015). Estradiol levels ranged from 50.0 pmol/l in Chinese women to 106.8 pmol/l in Vietnamese women; FSH ranged from 68.2 IU/l in Korean women to 90.8 IU/l in Malay women; and LH ranged from 30.7 IU/l in Korean women to 44.1 IU/l in Malay women. There was an inverse correlation between log E2 and FSH levels and a positive correlation between FSH and LH levels. The concentrations of E2, FSH and LH were significantly associated with ethnicity after adjustment for age and body mass index. Additionally, the concentrations of all three hormones were significantly associated with body mass index, whereas E2 and LH levels were associated with age, but FSH levels were not. CONCLUSION The levels of FSH, LH and particularly of E2 differ substantially among ethnic groups of postmenopausal Asian women. The clinical significance, if any, of these differences remains to be investigated. The inverse correlation of E2 and FSH levels suggests that E2 at the postmenopausal state still affects pituitary FSH output.

Abstract
The purpose of this study was to compare cycle control, efficacy and side effects of an oral contraceptive containing 20 microg ethinylestradiol and 75 microg gestodene, with a reference preparation containing 30 microg ethinylestradiol combined with 75 microg gestodene. From the study, it was demonstrated that the two regimens had no difference in cycle control, efficacy, and side effects. The occurrence of spotting and breakthrough bleeding was low and was not different between these two preparations. The most common adverse events in both treatment groups were nausea, vomiting, dizziness, and chloasma. There were no statistically significant change in body weight and blood pressure in both groups at the end of study. It is concluded that both preparations are good cycle control, reliable and low side effects oral contraceptives.

Abstract
This prospective analysis was conducted to compare the effects of hormone treatments on bone mineral density (BMD) of the lumbar spine, hip, and distal forearm in postmenopausal women with normal BMD and those with low bone mass. Eighty healthy women were randomly assigned to receive a cyclic regimen of standard hormone replacement therapy (HRT) or currently used low-dose oral contraceptive (OC). Women were categorized as normal BMD and low bone mass according to the Thai reference database. The results revealed that women with low bone mass gained more BMD than those with normal BMD. The difference in mean per cent bone acquisition was obvious at the spine. In addition, further subset analysis into OC and HRT groups revealed higher effects of OC on BMD when compared to HRT.

Abstract
OBJECTIVES To evaluate the contraceptive reliability and clinical effects of a monophasic oral contraceptive containing 20 microg ethinylestradiol and 150 microg desogestrel (Mercilon) in Thai women. METHOD The study was carried out at the Family Planning Clinic of King Chulalongkorn Memorial Hospital, Bangkok, Thailand. One hundred and forty six healthy women of fertile age were enrolled and treated with the study oral contraceptives for 12 cycles. Clinical data of vaginal bleeding, side effects, blood pressure and body weight were assessed periodically. RESULTS One thousand four hundred and twenty five cycles were evaluated. No conception occurred. The cycles were almost regular. The incidence of irregular bleeding was highest in the first cycle, after the third cycle, the value was below 4 per cent. Side effects were very few. There was no change in blood pressure. A slight decrease in mean body weight was observed. CONCLUSION The oral contraceptive containing 20 microg ethinylestradiol and 150 microg desogestrel has high contraceptive efficacy, good cycle control and minimal side effects.

Abstract
OBJECTIVE To determine the age-specific and age-adjusted prevalence of osteopenia and osteoporosis in pre- and postmenopausal Thai women. METHODS This was a descriptive study of 1,935 Thai women ranging in age from 40 to 80 years, with randomly selected strata using multistage sampling and stratifying from six representative provinces of the country. After recruiting, all the women were interviewed by a well-trained interviewer using structured questionnaires. Bone mineral density (BMD) of lumbar spine 1-4 and nondominant hip was measured by a dual energy photon absorptiometer. The investigators were trained and standardized; inter- and intraobserver variations were measured periodically. Every BMD outcome was re-examined by the specialist. Age-specific prevalence of osteoporosis and osteopenia were determined using both Thai and Western standard BMD values. Age-adjusted prevalence of osteopenia and osteoporosis was calculated using the age-adjusted direct method. RESULTS Using the Thai BMD reference, the age-specific prevalence of osteoporosis among Thai women rose progressively with increasing age to more than 50% after the age of 70. The age-adjusted prevalence of osteoporosis also rose progressively. It was 19.8%, 13.6%, and 10% for lumbar spine, femoral neck, and intertrochanteric. The age-adjusted prevalence of osteoporosis indicates the overall magnitude of that condition in the population or country. In our study, using a Western BMD reference resulted in a misleadingly high prevalence of osteoporosis in the population of Asian countries. CONCLUSION It is important to calculate the age-adjusted prevalence of osteopenia and osteoporosis to address the overall magnitude of the problem in Thai women. This will allow us to predict the socioeconomic impact of preventable chronic conditions such as osteoporosis. The results obtained from this study are important data for public health policy: maximizing bone mass throughout life as well as detection of important risk factors is essential.

Abstract
OBJECTIVE To find the reference data for age-specific normal bone mineral density in a Thai female population. STUDY DESIGN Cross-sectional, Descriptive study. MATERIAL AND METHOD 1773 Thai women aged between 11-80 years were recruited, using multistage cluster sampling and stratifying from six represented provinces in the country, each strata was randomly selected. After recruiting, the women were interviewed by well-trained personnel using structured questionnaires. Bone mineral density of the lumbar spine 1-4 and nondominant hip were measured by Dual Energy Photon Absorptiometer. The scientists, X-rays technician were trained and standardized inter and intra observers variation. Quality control of examination was measured periodically. Every BMD outcome was re-examined by a specialist. RESULTS The peak bone mineral density of both spines and hips was between the age of 30 to 34 years old. Mean Value for spine and femoral neck was 0.957 and 0.814 g/cm2 respectively. The BMD of spine and hip was significantly decreased after the age of 35 and the loss was accelerated at age 50. Osteoporosis for spine and femoral neck is considered when BMD are below 0.682 and 0.569 g/cm2 respectively. CONCLUSION The results are important data for public health policy, by maximizing bone mass during skeletal growth before menopause and minimizing bone loss throughout life as well as for detection of important risk factors.

Abstract
The study of effects on weight and blood pressure in long term DMPA acceptors is reported. The objectives were to study body weight and blood pressure changes in long term DMPA users compared with intrauterine device (IUD) acceptors. A total of 50 healthy women who had been using DMPA for 120 months were compared with 50 IUD acceptors who had been using an IUD for 120 months. Age, parity, income, body weight, and blood pressure at the initiation of contraception were matched. The mean +/- SD body weight at 120 months in the DMPA and IUD groups were 60.9 +/- 7.5 kg and 62.1 +/- 9.3 kg. No difference in mean body weight was demonstrated. The blood pressure change between DMPA and IUD acceptors also was not different. It is suggested that long term DMPA use does not have unfavorable effects on weight or blood pressure.

Abstract
This prospective analysis was done in 95 postmenopausal women to observe bone loss rate between 59 natural and 36 surgical menopausal women with or without hormonal replacement therapy (HRT). Bone mass measurement was performed at lumbar spines (L1-L4) and hip by dual energy X-ray absorptiometer at 0, 6 and 12 months. The results revealed that in the non-HRT group there was significant faster bone loss rate of lumbar spines (LS) and hip (H) of the surgical group at 12 months (Natural group: LS = -1.11%, H = +2.38%; Surgical group: LS = -4.51%, H = -0.66%, P < 0.05). However, there was no significant difference in bone changes of lumbar spines and hip between natural and surgical group with HRT at 12 months (Natural: LS = +2.0%, H = +4.06%; Surgical: LS = +0.62%, H = +2.28%, P > 0.05). This observation showed that without HRT oophorectomized women had greater magnitude of bone loss than women who entered menopause naturally.

Abstract
To assess the effect of hormonal replacement therapy on lipid changes, measurement of serum total cholesterol (TC), triglycerides (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), apolipoprotein A-1 (Apo-A) and apolipoprotein B (Apo-B) was performed on 93 postmenopausal women. Women in the study group (HRT) (51/93) received estrogen with or without progestin. The control group (Non-HRT) (42/93) did not receive any hormone regimen. The measurement was done at 0, 6 and 12 months. The results revealed that triglyceride increased significantly more in the non-HRT than the HRT group at 6 and 12 months. (Non-HRT: +21.7%, +21.7%; HRT: -2.8%, +2.4%, respectively P < 0.05). However, there was no significant difference in changes of other lipid profiles between the two groups at 6 and 12 months (Non-HRT: TC -2.7%, +0.7%, HDL +2.9%, +5.1%, LDL -5.2%, -4.1%, Apo-A +0.5%, +0.9%, Apo-B +3.8%, +1.3%: HRT: TC -1.4%, -2.8%, HDL +4.7%, +6.2%, LDL -1.5%, -4.9%, Apo-A -0.9%, +1.6%, Apo-B -2.6%, -1.6%, respectively P > 0.05). The paradoxical changes of triglyceride and HDL might partly be explained by the effect of progestins used in this study.

Abstract
UNLABELLED Bone mass measurement was performed in 95 healthy postmenopausal women to assess the effect of hormonal replacement therapy (HRT) on bone changes. Women in the study group (51/95) received estrogen with or without progestin. The control group (44/95) did not receive any hormone regimen. The measurement was done at lumbar spines (L1-L4) and hip by dual energy X-ray absorptiometer at 0, 6 and 12 months. The results revealed significantly higher per cent changes of bone density of lumbar spines and hip, at 12 months, in the study group than in the control. ( STUDY Lumbar Spine +1.76%, Hip +3.57%; CONTROL Lumbar spines -2.32%, Hip +1.32%, P < 0.05). In conclusion, this study showed the value of hormonal replacement therapy for prevention of postmenopausal bone loss in Thai women.
