Assessment of Knowledge Regarding Osteoporosis among Pre-Menopausal Women residing in Selected Rural Communities

Background: As a woman approaches menopause there are gradual changes in the physiology of her body. One of the prominent changes is an increase in the fragility of bone due to calcium variation causing Osteoporosis. A low level of estrogen, which occurs around the time of menopause leads to increased bone loss. A woman can undergo either primary or secondary osteoporosis. In most cases, the first 'symptom' of osteoporosis is broken bone. As osteoporosis is an emerging health problem, that creates an economic burden, it needs a special focus to promote healthy ageing. Knowledge is the best contributor to reducing the risk of premenopausal women getting osteoporosis. Methods: Total 70 pre-menopausal women living in chosen rural communities in Bagalkot were chosen with a convenient sampling technique. A structured questionnaire developed by the researcher was used to gather information concerning knowledge about osteoporosis. Chi-square analysis was used to uncover the relationship between knowledge about osteoporosis with socio-demographic factors. Results: Total 24.28% of women were having good knowledge, 54.28% were having average knowledge, and 21.42% of women were having poor knowledge about osteoporosis. A significant relationship was attained between knowledge regarding osteoporosis and occupation (?2=14.20, p<0.007) and formal education (?2=16.22, p<0.039) at the position of the significance of 0.05. Conclusion: After evaluation of knowledge on the subject of osteoporosis among pre-menopausal women, it was found that most women had average knowledge regarding osteoporosis.

Clinical characteristics of hospitalized premenopausal patients with hyperuricemia / 中华全科医师杂志

Objective:To analyze the clinical characteristics of hospitalized premenopausal patients with hyperuricemia.Methods:The medical records of premenopausal women with hyperuricemia (serum uric acid ≥360 μmol/L during hospitalization) admitted in Peking Union Medical College Hospital from 2013 to 2018 were reviewed and the clinical data were analyzed.Results:A total of 2 099 patients were enrolled. Only 14.01% (294 cases) of the patients were concerned about hyperuricemia by physicians. Autoimmune diseases (32.11%, 674 cases), nephrotic disease (19.29%, 405 cases) and endocrine system diseases (9.72%, 204 cases) are the main reasons for hospitalization, while 6.34%(133 cases) of patients were in gestation. In terms of the etiology, renal diseases (49.35%, 1 035 cases), specific drug use (49.26%, 1 034 cases) were the main causes of secondary hyperuricemia in premenopausal women, followed by metabolic diseases (10.62%, 233 cases). There was no significant difference in serum uric acid level among premenopausal women of different ages ( H=4.47, P=0.107), but the etiology of hyperuricemia among patients of different ages had significant differences. The proportion of hyperuricemia in patients with cancer and metabolic syndrome,secondary to use of diuretics and anti-tuberculosis drugs had differences among different age groups ( χ2=90.96,52.89,19.26 and 6.41, P<0.05). Conclusion:Hyperuricemia is not uncommon in premenopausal women. There are many secondary factors leading to hyperuricemia in premenopausal women, among which drugs and renal lesions are the main causes. In addition, the secondary factors in women with hyperuricemia has differences among different age groups.

ABSTRACT Introduction: patients with systemic lupus erythematosus have a high risk of presenting low bone mass. The etiology is multifactorial (traditional risk factors, characteristic of the disease, laboratory, serological, metabolic and those related to treatment). Objective: to determine the traditional risk factors for low bone mass (sedentary lifestyle, smoking, alcohol, low milk intake, low body mass index), those related to the disease (clinical presentation, laboratory), metabolic and treatment, with the decrease of bone mineral density in premenopausal women with systemic lupus erythematosus. Methodology: prospective analytical cross-sectional observational study of premenopausal women with systemic lupus erythematosus, who attended the National Hospital in the period October 2017 - October 2019. Bone mineral density was evaluated by DEXA densitometry, and the Z score was used, equal values or lower than -2,0 SD was considered low bone mass. The variables analyzed were: traditional risk factors for low bone mass, related to lupus, laboratory, serological, metabolic and treatment. Statistical analysis: mean and standard deviation for continuous variables were used to describe the variables; and proportions for qualitative ones. The risk factors for low bone mass were established by the Chi square test, considering a p value of ˂0,05 as significant; the Student's t test was used to compare means. Result: 61 premenopausal women were studied, with a mean age 25,6 ± 7 years, being from the interior of the country 50,8 % and Central 49,18 %. They had secondary studies 54,10 %, tertiary 34,43 %, primary 11,48 %. 40,98 % were sedentary. 21,31 % had a low milk intake and 1,64 % was an active smoker. They were 66,2 % normal weight, 15,25 % overweight, 18,33 % obese, 1,64 % underweight. The mean time of illness was 50,5 ± 56,4 months. The disease activity index (SLEDAI) was 6,5 ± 6,5. 31,5 % had a duration of the disease greater than 5 years. They had lupus nephritis 52,54 %, severe activity 24,5 %, hypocomplementemia 45 %. Mean ANA 995,5 ± 1164, mean anti DNA 274,2 ± 830,8, anti Ro positive 54,7 %, anti Sm positive 24,5 %.

Association between cadmium and anti-Mullerian hormone in premenopausal women at particular ages

BACKGROUND: Anti-Mullerian hormone (AMH) in women is secreted by granulosa cells of antral follicles. AMH appears to be a very stable marker for ovarian function. It may be used to diagnosis cases of premature ovarian failure, polycystic ovary syndrome (PCOS), and ovarian tumors. It has been suggested that cadmium exposure can reduce female fecundity. The purpose of this study was to investigate whether environmental exposure to cadmium was associated with alterations in AMH with regards to age. METHODS: In a cross-sectional study, the data of premenopausal women living in Seoul, ranging from 30 to 45 of age was collected. The study included a total of 283 women who completed serum AMH and whole blood cadmium assessments. Linear regression analyses were used in order to examine the association between cadmium and AMH. Given that age was the strongest confounder in both cadmium and AMH concentrations, we stratified subjects by 5 years old and analyzed their data. RESULTS: Geometric mean concentrations of blood cadmium and AMH were 0.97 μg/L and 3.02 ng/ml, respectively. Total association between cadmium and AMH was statistically significant (adjusted coefficient = − 0.34 (0.15), p = 0.02). After stratification, the only age group with a negative association between cadmium and AMH were the women raging between 30 and 35 years (adjusted coefficient = − 0.43 (0.18), p = 0.01). CONCLUSIONS: The results of this study suggest that environmental exposure to cadmium may alter the AMH level of premenopausal women, depending on their age group.

Prevalencia de causas secundarias de baja masa ósea en una población de mujeres premenopáusicas / Prevalence of secondary causes in a population of premenopausal women with low bone mass

La osteoporosis es un trastorno común en las mujeres posmenopáusicas; sin embargo, también puede afectar a hombres y mujeres jóvenes premenopáusicas. El objetivo del presente trabajo fue evaluar la prevalencia de causas secundarias de baja masa ósea en un grupo de mujeres premenopáusicas que consultaron en una Institución especializada en Osteología. Material y métodos: se realizó un estudio retrospectivo, de corte transversal, descriptivo y observacional. Se analizaron las historias clínicas de 88 pacientes que consultaron por baja masa ósea durante un período de 19 meses, con la finalidad de encontrar posibles causas secundarias. A su vez, se definió como pacientes con diagnóstico de baja masa ósea idiopática aquellas en las cuales no se encontró ninguna causa secundaria de pérdida ósea. Resultados: de las 88 mujeres evaluadas, el 48,9% presentaba al menos una causa secundaria para baja masa ósea (amenorrea secundaria, hipercalciuria, tratamiento con glucorticoides, hipovitaminosis D y enfermedad celíaca) y el 51,1% fueron consideradas idiopáticas. Conclusiones: es esencial evaluar exhaustivamente a las mujeres premenopáusicas con baja masa ósea a fin de descartar posibles causas secundarias y tomar las medidas preventivas necesarias para mejorar esa condición.

Blood cadmium and volume of uterine fibroids in premenopausal women

BACKGROUND: A number of studies have found associations between heavy metals and uterine fibroids, but the results are inconsistent. Here, we conducted this research to demonstrate the relationships between blood heavy metal concentrations and uterine fibroid volume as well as the rate of uterine fibroid presence. METHODS: In a cross-sectional study, we collected data from 308 premenopausal women aged 30–49 years in Seoul; uterine fibroids are ascertained by past history of myomectomy and pelvic ultrasonography. In the analytic phase, we first analyzed the presence of the fibroids and the concentrations of heavy metals via logistic regression. In subgroup analysis, we used simple and multiple linear regression analyses to examine the associations between heavy metals and uterine fibroid volume. RESULTS: There was no connection between the heavy metal concentrations and the presence of uterine fibroids, but the odds of women having fibroids were higher with three particular metals. In subgroup analysis, the association between blood cadmium concentrations and uterine fibroid volume was statistically significant (adjusted beta coefficient = 2.22, 95% confidential interval: 0.06–4.37). In contrast, blood mercury and lead concentrations were not significantly associated with uterine fibroid volume. CONCLUSIONS: Our findings are the first that we know to report the association of blood cadmium concentrations with the volume of uterine fibroids. We expect that our findings will be used as evidence for supporting policies to improve premenopausal Korean women's health.

Short-term influence on ovarian reserve in premenopausal women with hysterectomy plus salpingectomy / 医学研究生学报

Objective The risk of ovarian/pelvic serous cancer can be reduced by prophylactic bilateral salpingectomy ( PBS) at the time of hysterectomy .This study was to evaluate the short-term influence of PBS plus hysterectomy on ovarian reserve in premenopausal women . Methods We retrospectively analyzed the clinical data about 60 premenopausal women treated by total lapa-roscopic hysterectomy ( TLH) for benign indications , 30 undergoing PBS at the same time ( the experimental group ) while the other 30 with the ovary preserved ( the control group ) .We compared the levels of FSH, LH, E2, and anti-Müllerian hormone ( AMH) and the inci-dence of peri-menopausal symptoms between the two groups of patients before and at 1 and 3 months after operation . Results Statistically significant differences were not observed between the two groups in the such baseline clinical characteristics as age , gravidity, parity, men-strual cycle, comorbidity, diagnosis, comorbidities, and history of abdominal surgery (P>0.05), nor in the AMH level at the baseline ([1.08±0.08] vs [1.04±0.10] ng/mL) or at 1 month ([0.86± 0.44] vs [0.81±0.48] ng/mL) or 3 months postoperatively ([0.84±0.94] vs [0.68±0.42] ng/mL) (F=0.247, P=0.746).Howev-er, the mean level of AMH was markedly reduced at 1 and 3 months after operation as compared with the baseline ( P0.05) .There were not any statistically significant differences in the levels FSH, LH, and E2 between the two groups before or at 1 and 3 months after surgery (P>0.05), nor in the incidence rates of peri-menopausal symptoms at 1 month (6.7%vs 3.3%, P>0.05) or 3 months postoperatively (10.0%vs 6.7%, P>0.05). Conclusion PBS at the time of total hysterectomy in premenopausal women does not affect ovarian reserve in the short term .The level of AMH has a higher sensitivity than those of FSH , LH and E2 in the assessment of postoperative ovarian function .

Analysis of osteoporosis related factors in premenopausal patients with early rheumatoid arthritis / 中华风湿病学杂志

Objective To identify the clinical features and risk factors of early rheumatoid arthritis (RA)-associated osteoporosis in premenopausal women. Methods A total of 76 premenopausal women with early RA were randomly selected in the Department of Kidney and Rheumatology in the hospital. A total of 84 health cases were randomly selected in our hospital as controls. Bone mineral density (BMD) was determined using dual energy X-ray absorptiometry (DEX). Bone metabolism (CTX, PINP) and inflammatory cytokines (IL-17, IL-6, TNF-α) were examined with quantitative enzyme-linked immune-sorbent assay (ELISA). Quantitative data were expressed as x ±s deviation and the data were compared between groups using non- parametric test (Z value). Multi-group comparison was performed with variance analysis. Qualitative data were compared with Fisher's test. Logistic regression was used to investigate the risk factors. Results ①Compared with the control group, BMD in the premenopausal women with early RA group [neck: (0.802 ±0.193) g/cm2, GT zone: (0.923±0.033) g/cm2, L1: (0.862±0.011) g/cm2] was significantly decreased [(0.981±0.032) g/cm2, (0.771 ±0.023) g/cm2, (0.912 ±0.012) g/cm2, F=14.401, 19.860, 6.560, respectively, both P<0.05). The prevalence of osteoporosis in this group was 7%(5/76), which was higher than controls 1%(1/84). ② According to values of Bone meta-bolism [(CTX: (0.37±0.21) ng/ml] and inflammatory cytokines, TNF-α: (9.8±4.1) pg/ml, IL-6: (33.6±5.7) pg/ml and IL-17: (129±24) pg/ml were markedly increased in premenopausal women in early RA group [(0.24 ±0.09) ng/ml, (6.7 ±1.9) pg/ml, (1.5 ±0.4) pg/ml, (45 ±7) pg/ml, Z=2.722, 5.932, 7.501, 4.370, respectively, both P<0.05]. ③ The premenopausal women with early RA group with osteoporosis were signifi- cantly difference with controls in BMI [(9±3) kg/m2 vs (16±3) kg/m2], bone density of neck [(0.85±0.20) ng/ml vs (0.88±0.14) g/cm2], L2 [(0.75±0.23) g/cm2 vs (0.88±0.14) g/cm2], L3 [(0.87±0.07) g/cm2 vs (0.93±0.14) g/cm2], L4 [(0.92±0.12) g/cm2 vs (0.94±0.16) g/cm2], serum ESR [47.8(22.0, 76.0) mm/1 h vs 18.8(8.7, 35.2) mm/1 h] and DAS28-CRP (5.3 ±1.2 vs 3.8 ±1.2) F=0.68, 14.632, 26.114, 20.931, 36.582, Z=3.21, 6.58, respectively, both P<0.05. ④ Logistic regression showed that IL-6 (Wald χ2=5.78, P=0.021), PINP (Wald χ2=5.12, P=0.031), CTX (Wald χ2=9.17, P=0.003), ESR (Wald χ2=9.24, P=0.011), DAS28-CRP (Wald χ2=17.28, P=0.001) were significantly positively correlated with osteoporosis. Moreover, ordered unconditional Logistic regression analysis of the variables (IL-6, PINP, CTX, ESR, DSA28) described above showed that DAS 28-CRP score [OR=1.58, 95%CI: (1.10, 2.20)] was the most important risk factor for osteoporosis in premenopausal women with early RA. Conclusion The incidence of osteoporosis is high in premenopausal women with early RA than healthy cases. DAS 28-CRP score is the important risk factor for premenopausal women with early RA- associated osteoporosis. Measures relieve symptoms of RA can help to prevent and treatment osteoporosis.

Comparison of cardiac vagal activity between pre and postmenopausal women using heart rate recovery.

Ageing is associated with an increase in Heart Rate Recovery (HRR). HRR is a property of vagal activity. But there is little evidence regarding the extent to which age-related changes in HRR depend on simultaneous transition from pre-menopausal state to postmenopausal state. The purpose of this study was (i) to compare HRR between pre and postmenopausal women, (ii) to compare heart rate recovery between men of age group 40-45 years and 45-50years respectively (iii) and to determine whether difference in age, gender and body composition could account for the difference in HRR between pre- and post-menopausal groups. Methods: HRR was assessed using modified Bruce exercise protocol. The body mass index was assessed by measuring weight and height of the subject. Data was analyzed after adjusting for age and body composition. Results: It was found that the HRR were significantly higher (P <0.001) in postmenopausal women compared to that of premenopausal women. Analysis after adjusting for age and gender revealed that men of same age group didn’t undergo much change in HRR as compared to women. Conclusions: The study concludes that both ageing and declined oestrogen levels are associated with the increased Hear Rate Recovery (HRR) seen among postmenopausal women.

Association Between Anthropometric Status, Dietary Intake and Physical Activity with Bone Health Status among Premenopausal Chinese Women in the Klang Valley, Malaysia

Introduction: There is a lack of information on bone health status of premenopausal women in Malaysia. This study investigated the bone health status of premenopausal women and its associations with anthropometric, dietary and physical activity. Methods: Bone mineral density (BMD) was measured using dual X-ray absorptiometry (DEXA) at the lumbar spine, femoral neck, total hip and total body. Serum osteocalcin, parathyroid hormone (PTH), beta-crosslaps were also determined. Results: A total of 73 Chinese premenopausal women were recruited in the study with a mean age of 39.3 � 5.0 years. Average BMI, body fat percentage and lean body mass were 22.2 � 3.4 kg/m2, 33.9 � 4.6% and 34.5 � 4.4 kg, respectively. Mean BMD at the spine, total hip, femoral neck, and total body were 1.025 � 0.118 g/cm2, 0.876 � 0.109 g/cm2, 0.739 � 0.110 g/cm2, and 1.061 � 0.755 g/cm2, respectively. Their serum beta-crosslaps and PTH were within normal range, but serum osteocalcin (8.5 � 4.2 ng/ml) was low. On average, calorie intake (1506 � 427 kcal/day) was below the Malaysian Recommended Nutrient Intake (RNI) while their calcium intake achieved only 67% of RNI. Their mean metabolic equivalent score (MET) was 771.4 � 926.1 mm/week. Body weight and related indices (BMI, lean mass, fat mass) were significantly positively correlated with BMD at all skeletal sites. Conclusion: The study revealed that Chinese premenopausal women in the Klang Valley have low calcium intake and low level of physical activity.

Relationship Between Parasympathetic Nerve Function and Ovarian Hormones During Different Phases of Ovarian Cycle In Healthy Young Women.

Background: Women having regular ovarian cycle often experience premenstrual syndrome which may be associated with alterations of autonomic nerve function due to fluctuation of ovarian hormones during different phases of ovarian cycle. Objective: To observe the parasympathetic nerve function status and their relationships with ovarian hormones during different phases of ovarian cycle in healthy young women. Methods: This cross sectional study was carried out in the department of Physiology at BSMMU, Dhaka in 2007 on 30 eumenorrhogic healthy females aged 20 to 30 years. Serum estrogen and progesterone were measured by MEIA method and parasympathetic nerve functions were assessed by valsalva, deep breathing test and orthostatic test during follicular and luteal phases of ovarian cycle. Data were analyzed by paired student ‘t’ test, and Pearson’s Correlation coefficient test where applicable. Results: Mean resting HR,SBP,DBP and all measures of parasympathetic nerve function were similar in all phases of ovarian cycle. With serum estrogen level, deep breathing showed significant (p<0.05) positive correlation in follicular and luteal phase and valsalva showed significant positive correlation during luteal phase. Conclusion: The results this study suggest that estrogen has got positive influence on parasympathetic nerve function which support cardioprotective role of estrogen in premenopausal females.

A comparative study of serum lipid profile between premenopausal and postmenopausal women.

Background & objectives: The effect of the hormonal changes associated with menopause on the serum lipid levels may play an important role in most cardiac related disorders associated with menopause. So the present study was undertaken with the following objectives. 1) To study the serum lipid profile in premenopausal and postmenopausal women. 2) To compare the differences of serum lipid profile between premenopausal and postmenopausal women. 3) To study the effect of duration of menopause on serum lipid profile. 4) To correlate the results of present study with that of other studies. Methods: 50 premenopausal and 50 postmenopausal women were recruited for the study. The subjects having risk factors that may affect the lipid profile were excluded. 5 ml of venous blood was collected after overnight fasting of 12 hrs in all the subjects for estimation of serum levels of total cholesterol, HDL, LDL, VLDL and triglycerides. Results: As compared to premenopausal women, mean level of serum total cholesterol and serum LDL were significantly higher in postmenopausal women and level significantly increased with increase in the duration of menopause. While level of serum HDL was significantly lower in postmenopausal women and level significantly decreased with increase in the duration of menopause. There was no statistically significant difference in serum triglycerides and serum VLDL between premenopausal and postmenopausal women up to 10 years duration of menopause. However they increased significantly after > 10 years duration of menopause. Interpretation & conclusion: According to the present study, menopause is associated with altered serum lipid profile and thus an independent risk factor for developing cardiovascular diseases. Therefore it is important to consider each and every postmenopausal woman to undergo screening for abnormal lipid profile. In them, specific health education strategies are needed in an order to prevent the emerging cardiovascular diseases.

Relationship between Serum 25-hydroxyvitamin D Concentration and the Risks of Metabolic Syndrome in Premenopausal and Postmenopausal Women

Metabolic syndrome (MetS) has become a global epidemic. In particular, it is known that there is a dramatic increase in the prevalence of MetS among women during the postmenopausal period. Recently, accumulating studies have suggested that vitamin D deficiency may be inversely associated with the risk factors regarding MetS. However, evidence from postmenopausal women is limited. In this study, we examined the association between the serum 25-hydroxyvitamin D [25(OH)D] and the MetS in Korean adult women aged 20-69 years (n = 2,618) by using the 2007-2008 Korean National Health and Nutrition Examination Survey data. The geometric mean of plasma 25(OH)D were 17.16 +/- 6.28 ng/mL and 20.20 +/- 7.69 ng/mL for premenopausal and postmenopausal women, respectively. The percentages of vitamin D deficiency [25(OH)D < 12 ng/mL] were 22.5% and 14.4%, respectively. MetS was more prevalent in postmenopausal women (43.0%) compared with premenopausal women (11.2%). When serum concentrations of 25(OH)D were categorized in quintiles, there was no relationship in the prevalence of MetS in both premonopausal and postmenopausal women. However, in premenopausal women, compared with the lowest 25(OH)D quintile, the odds ratio for hypertriglyceridemia in the highest quintile was 0.57 (95% CI 0.34-0.95, Ptrend = 0.041) and for low serum HDL cholesterol 0.60 (95% CI 0.42-0.85, Ptrend = 0.014) after adjusting for all potential confounders. On the other hand, we observed the tendency of an inverse relationship for 25(OH)D regarding low serum HDL cholesterol (OR 0.78, 95% CI 0.50-1.22, Ptrend = 0.029) and a direct relationship with abdominal obesity (OR 1.94, 95% CI 1.01, 3.74, Ptrend = 0.049) in postmenopausal women. Further studies are needed to confirm these findings in other research settings.

Comparison of cardiac autonomic functions among postmenopausal women with and without hormone replacement therapy, and premenopausal women.

The aim of present study was comparison of cardiac autonomic status during different phases of reproductive life in women – in premenopausal women between proliferative and secretory phase, in postmenopausal women and in postmenopausal women receiving hormone replacement therapy (HRT). The study included 30 premenopausal women (Group 1) who were assessed in both proliferative (Group 1A) and secretory phase (Group 1B) of menstrual cycle, 30 postmenopausal women (Group 2) and 30 postmenopausal women on HRT (Group 3). Various autonomic function tests were done to assess parasympathetic and sympathetic functions. Results were obtained by ANOVA followed by Tukey test. The postmenopausal women (Group 2) showed increased sympathetic and decreased parasympathetic tone compared to premenopausal women (Groupl). The women on HRT (Group 3) showed parasympathetic dominance and decrease in sympathetic activity compared to postmenopausal women (Group 2). Across the menstrual cycle, increased parasympathetic activity was seen in secretory phase while no change was observed in the sympathetic activity in the two phases.

The Association between Bone Mineral Density, Bone Turnover Markers, and Nutrient Intake in Pre- and Postmenopausal Women

The purpose of this study was to examine the association among bone mineral density (BMD), biochemical bone markers, nutrients, and salt intake in premenopausal and postmenopausal women. We evaluated 431 subjects who visited a health promotion center of a university hospital between January 2008 and July 2009. We excluded those who were taking medications or who had an endocrine disorder affecting osteoporosis. The subjects were divided into premenopausal (n = 283) and postmenopausal (n = 143) women. We evaluated the correlation among BMD of the lumbar spine, femoral neck, and total femoral, as well as biochemical bone markers, hormone, serum profiles, general characteristics, nutrient intakes, and food intake frequencies. From a stepwise multiple regression analysis, lumbar spine BMD was positively correlated with weight (p < 0.001) and negatively correlated with osteocalcin (OC)(p < 0.001), Femoral neck BMD was positively correlated with weight (p < 0.001) and negatively correlated with C-telopeptide (CTx) and alkaline phosphatase (ALP)(p < 0.001, p < 0.05). In premenopausal women, femoral total BMD was positively correlated with BMI (p < 0.001) and negatively correlated with CTx (p < 0.001). In postmenopausal women, lumbar spine BMD was positively correlated with calcium intake (p < 0.01) and negatively correlated with sodium intake (p < 0.01). Femoral neck and femoral total BMD were both positively correlated with weight (p < 0.001), and femoral neck BMD was negatively correlated with age and ALP (p < 0.001, p < 0.05). Femoral total BMD was negatively correlated with age and OC (p < 0.001, p < 0.01). These results suggest that reducing sodium intake may play an important role delaying bone resorption and preventing a decrease in BMD.

Comparison of Factors Which Influence the Brachial-Ankle Pulse Wave Velocity in Pre- and Postmenopausal Women / 대한폐경학회지

OBJECTIVES: The aim of this study was to compare the factors which influence the brachial-ankle pulse wave velocity (baPWV) in pre- and post-menopausal women. We also investigated the association of menopause with arterial stiffness measured by baPWV. METHODS: We performed a retrospective review of 241 postmenopausal women who attended the health promotion center for a routine checkup. Simple and multiple regression analyses were performed to determine the parameters influencing baPWV in pre- and postmenopausal women. Multiple logistic regression analysis was performed to identify the independent parameters related to increased of arterial stiffness. RESULTS: Multiple regression analysis showed that diastolic blood pressure (DBP; beta = 0.402, P = 0.009) was identified as an independent determinant for baPWV in premenopausal women, and DBP (beta = 0.329, P = 0.021) and the neutrophil-to-lymphocyte ratio (NLR; beta = 0.210, P = 0.016) were identified as independent determinants for baPWV in postmenopausal women. The odds ratio (95% CI) of menopause for a high baPWV was 2.666 (1.025~6.937). CONCLUSION: The NLR is associated with arterial stiffness in postmenopausal women. Consequently, inflammation is thought to play a crucial role in increased arterial stiffness in postmenopausal women. Menopause is associated with a high baPWV, suggesting that changes in the concentrations of sex hormones during the menopausal transition may influence arterial stiffness in clinically healthy women.

Risk Factors and Assessment of Low Bone Mass in the Young Adult Female / 가정의학회지

Although low bone mass and accelerated bone loss can occur early in life, osteoporosis is usually considered a disorder of postmenopausal women. However, some premenopausal women are also at risk for osteoporosis. Because of a lack of knowledge and few practice recommendations for premenopausal women, it can be more difficult to determine the potential risk and to manage the low bone mass in these women. Low bone density in the young adult female may reflect attainment of a lower peak bone mass or be secondary to progressive bone loss following attainment of peak bone density. Early bone health is a key determinant of future osteoporosis, optimizing the bone gain by young adulthood and minimizing the bone loss by menopause is the important preventive strategies. Low bone mass in the young adult female may be associated with prolonged amenorrhea, anorexia nervosa, chronic glucocorticoid therapy and diseases that affect calcium and vitamin D metabolism. Also, bone loss may be associated with common conditions such as smoking, dieting, low calcium intake, and low physical activity. This review addresses peak bone mass accrual, risk factors, screening or evaluation and management of low bone mass in young adult female.
