Menopause experience and the relationship between metabolic syndrome components and periodontitis / 대한구강보건학회지

OBJECTIVES: The purpose of this study was to investigate the correlation of periodontitis with metabolic syndromes and menopause status. METHODS: The 2013 Korea National Health and Nutrition Examination Survey data of 645 postmenopausal and 663 premenopausal women were analyzed using the Pearson's chi-squared test and multiple regression analysis with the Statistical Package for the Social Sciences (PASW statistics) software version 21.0. Metabolic syndromes and community periodontal index (CPI) were analyzed. RESULTS: CPI 3, CPI 4 (P<0.001), and the prevalence of periodontal disease were significantly higher in the postmenopausal group (P<0.001). Periodontal disease was significantly higher (P<0.001) in postmenopausal women not using dental floss (2.69 times), hypertensive postmenopausal women (1.60 times), and premenopausal women with high blood glucose levels (1.67 times). In the multiple logistic regression analysis, after adjusting for age, smoking habit, and alcohol consumption, significant risk factors for periodontal disease were the lack of dental floss use (odds ratio [OR]: 1.83; 95% confidence interval [CI]: 1.26–2.67), menopause (OR: 1.71; 95% CI: 1.22–2.41), and number of metabolic syndromes (when 1 or 2, OR: 2.22 and 95% CI: 1.50–3.29; when 3 or more, OR: 2.22 and 95% CI: 1.58–3.13). CONCLUSIONS: In summary, menopause status is associated with periodontal disease. Therefore, oral health programs for middle-aged women with menopause and metabolic syndromes should be conducted to improve their oral health-related quality of life.

Influence of menopause status on breast fibrograndular tissue and background parenchymal enhancement / 复旦学报（医学版）

Objective To evaluate the influence of menopause status on breast fibrograndular tissue (FGT),background parenchymal enhancement volume ratio (BPEv) and intensity ratio (BPEI) by breast MR image automatic quantitative analysis.Methods From 14 033 consecutive patients who underwent breast MR in our center from 2009 to 2012,we randomly selected 101 normal cases (47cases of premenopausal and 54 cases of postmenopausal).Premenopausal status was subclassified into four groups (8 cases in the 1st week and 13 cases in the 2nd,3rd and 4th week,respectively) based on the menstrual cycle.We evaluated FGT,BPEv and BPEI at early (2 minutes),medium (4 minutes) and late (6 minutes) enhanced time phases of breast MRI for quantitative assessment.The FGT,BPEv and BPEI in premenopausal and postmenopausal women were compared using the Mann-Whitney U test.Comparison of each menstrual cycle was made using the Kruskal-Wallis test.Results The FGT,BPEv and middle-late BPEI of postmenopausal women were significantly lower than that of premenopausal women (P＜0.05).The maximum BPEI was in the 1st week,the minimum in the 2nd week in premenopausal women (P＜0.05).The FGT and BPEv in the 1st week were the highest among the 4 weeks,but there was no significant difference.Conclusions The FGT,BPEv and BPEI were significantly decreased after menopause.The optimal time of breast MR examination is in the 2nd week of menstrual cycle.
