Effects of the levonorgestrel-releasing intrauterine system plus estrogen therapy in perimenopausal and postmenopausal women: systematic review and meta-analysis.

Objective:The objective of this study was to compare the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) with those of systemic progestogen in perimenopausal and postmenopausal women taking systemic estrogen therapy (ET). Methods:We searched Medline (August 8, 2009), Embase (August 8, 2009), the Cochrane Central Register of Controlled Trials on the Cochrane Library Issue 3 (2009), the MetaRegister of Controlled Trials, and the reference lists of articles for relevant trials. Randomized controlled studies of LNG-IUS versus systemic progestogen in perimenopausal and postmenopausal women taking ET were included in the review. Two reviewers abstracted the trials independently. Any disagreement was resolved through discussion with the third reviewer. For dichotomous outcomes, a Peto odds ratio was calculated. For continuous outcomes, nonskewed data from valid scales were synthesized using a weighted mean difference or a standardized mean difference. Results:Six trials with a total of 518 participants were included. The methodological limitation was an attrition bias. In perimenopausal and postmenopausal women taking ET, the incidence of a proliferative endometrium was comparable between the use of systemic progestogen and LNG-IUS, except for sequential medroxyprogesterone acetate, which had a higher incidence of proliferative endometrium. Descriptive data synthesis showed that ET combined with either LNG-IUS or systemic progestogen effectively relieved climacteric symptoms. Vaginal bleeding and spotting were common in the LNG-IUS group for the first 3 to 6 months of use. The discontinuation rate was not different. There was insufficient evidence to draw any conclusions about the other outcomes. Conclusions:The LNG-IUS was more effective than sequential medroxyprogesterone acetate but was comparable with other systemic progestogen regimens for endometrial protection in perimenopausal and postmenopausal women taking ET.

Premenstrual syndrome (PMS) among high school students

Background Premenstrual syndrome (PMS) is a common health problem among adolescents. Objective To assess the prevalence of PMS in Thai high school students. Materials and methods This was a prospective study conducted among menstruating high school students in Khon Kaen, Thailand, from September to December, 2015. Participants were asked to prospectively complete an anonymous questionnaire, which included information about demographic data, menstrual patterns, and symptoms to be recorded on a daily calendar of premenstrual experiences according to the diagnostic criteria proposed by the American College of Obstetricians and Gynecologists. All of the data were prospectively recorded for 90 consecutive days. Results Of the 399 participants, 289 (72.4%) completed the self-report questionnaire. Eighty-six participants (29.8%; 95% CI, 24.5%–35.4%) reported having PMS. The most common somatic and affective symptoms among participants with PMS were breast tenderness (74.4%) and angry outbursts (97.7%). There were significant differences between the PMS and non-PMS groups, and PMS was associated with various problems related to educational activities, including lack of concentration and motivation, poor individual work performance, poor collaborative work performance, and low scores. However, there were no significant differences regarding interpersonal relationships between the PMS and non-PMS groups. Conclusions PMS is a common menstrual disorder among Thai high school students. The most common symptoms reported in this study were angry outbursts and breast tenderness.

Adequacy of calcium intake during pregnancy in a tertiary care center

Background Calcium is an essential element for the body, which is taken through the dietary sources. Calcium supplements may be needed to achieve the dietary reference intake (DRI). Dietary calcium and supplemental calcium intake for calcium balance might be necessary. However, increasing evidence shows that calcium supplementation may enhance soft tissue calcification and cause cardiovascular diseases. Calcium requirement during pregnancy is markedly increased. If calcium supplementation depends on the dietary style of a region, then the adequacy of dietary calcium intake may guide the calcium supplementation. Materials and methods A cross-sectional descriptive study was conducted among pregnant women who attended prenatal care at Srinagarind Hospital, Khon Kaen University. We used semiquantitative food frequency questionnaire (SFFQ) to evaluate the amount of daily calcium intake, and 3 days food record to assess the SFFQ reliability. We used the INMUCAL-N V.3.0, based on the Thai food composition table for nutritional calculation. Results Among 255 recruited pregnant women, the mean daily dietary calcium intake was 1,256.9 mg/day (SD: 625.1) and up to 1,413.4 mg/day (SD: 601.3) in daily milk consumed group. Based on Thai DRI for pregnant women, with 800 mg/day as adequate intake of calcium, 74.9% had adequate calcium intake, and majority of them had milk daily. Conclusion The majority of pregnant women in a province of Northeast Thailand had adequate calcium intake, particularly those who had milk with their meal every day.

Effects of sunlight exposure and vitamin D supplementation on vitamin D levels in postmenopausal women in rural Thailand: A randomized controlled trial

BACKGROUND Despite the abundant sunlight in Thailand, vitamin D deficiency is common in premenopausal and postmenopausal Thai women. Sunlight exposure is a natural way to increase ones intake of vitamin D. However, limited research has been conducted regarding natural exposure to sunlight as a strategy to improve vitamin D status in postmenopausal women. OBJECTIVE This study aimed to determine the effects of sunlight exposure compared with oral supplementation with vitamin D2 (weekly 20,000 IU) in combination with sunlight exposure on 25(OH)D levels. METHODS A 12-week randomized controlled trial was conducted in 52 postmenopausal women, age 50-70 years. The participants were randomized to either the sunlight exposure group or the sunlight exposure with vitamin D supplementation group. Serum 25(OH)D concentration and parathyroid hormone (PTH) were measured using standard assays at baseline and 12 weeks. RESULTS After 12 weeks, mean serum 25(OH)D had decreased from 32.3 to 29.7 ng/ml in the sunlight exposure group, but significantly increased in the combination group (from 29.9 to 32.4 ng/ml). At the end of the study, 25(OH)D levels were significantly higher in the sunlight exposure with vitamin D supplementation group compared with the sunlight exposure group. However, this difference was not observed in women aged >60 years. Serum PTH had decreased in both groups, but not to a significant extent. CONCLUSION A combination of weekly vitamin D2 supplementation at a dose of 20,000 IU with sunlight exposure is more effective than sunlight exposure alone in postmenopausal Thai women. Sunlight exposure alone is not sufficient to maintain 25-hydroxyvitamin D levels in this setting.

Carotid intima-media thickness and osteoporosis in postmenopausal women: a cross-sectional study

Abstract Objectives: To explore the difference in carotid intima-media thickness (CIMT) between postmenopausal women with and without osteoporosis and the risk of elevated CIMT and plaque presentation. Method: A cross-sectional study was conducted including 46 postmenopausal women with osteoporosis and 45 non-osteoporotic postmenopausal women. CIMT was measured using B-mode ultrasound. Results: There was no statistically significant difference in mean CIMT between postmenopausal women with osteoporosis and those without osteoporosis (p > 0.05). Risk for elevated CIMT in the osteoporosis group was comparable to that of the non-osteoporosis group (adjusted odds ratio = 0.844; 95% confidence interval 0.11–6.45). The risk for the presence of plaque was three times higher in osteoporotic women than in normal individuals. However, after adjusting for age and underlying diseases that would predispose the women to cardiovascular disease, there was no significant difference in terms of presence of plaque between the two groups (adjusted odds ratio = 0.844; 95% confidence interval 0.11–6.45). Conclusion: There was no difference in mean CIMT between postmenopausal women with and without osteoporosis. Risk of elevated CIMT in postmenopausal women with osteoporosis was comparable to that of postmenopausal women without osteoporosis. There was no significant difference between the two groups in terms of the presence of plaque.
