Item Metabolic syndrome and risk of endometrial carcinoma among asymptomatic, postmenopausal, urban Sri Lankan females: a community cohort follow-up study(Wiley Publishing, 2017) Dias, T.; Niriella, M.; de Silva, S.; Motha, C.; Palihawadana, T.S.; Ediriweera, D.; de Silva, J.OBJECTIVES: Metabolic syndrome (MetS) has been recognised as a risk factor for malignancies. The aim of this study was to evaluate the association of MetS and risk of endometrial carcinoma (EC), by measuring endometrial thickness (ET). METHODS: The Ragama Health Study (RHS) recruited 35-64-year-old female cohort by age-stratified random sampling in 2007 and re-evaluated them in 2014, using a structured interview, anthropometric measurements and biochemical tests. Liver ultrasound to detect fatty liver was performed in 2007. Pelvic ultrasound to detect ET was performed in 2014 among consenting participants. MetS was diagnosed on established International Diabetes Federation (IDF 2012) criteria. Increased ET was defined as >5mm. Simple logistic regression was used to screen variables and multiple logistic regression was used to obtain adjusted effects of risk factors for increased ET. RESULTS: 813/1636(49.7%) of the original female cohort attended follow-up; ET was measured in 567(69.7%). Median (IQR) age of females was 61 (56-66) years. 323 fulfilled criteria for MetS (prevalence 57.1%) in 2007. 57(10.1%) had increased ET in 2014. Increasing plasma triglycerides [OR=1.004 per mg/dl, 95%CI:1.001-1.007, p<0.05] and being hypertensive [OR=2.16, 95%CI:1.11–4.08, p<0.05] were associated with increased ET, while advancing age [OR=0.93 per year, 95%CI:0.89–0.98, p<0.01] and being diabetic [OR= 0.34, 95%CI:0.10–0.89, p<0.05] were protective. CONCLUSIONS: Hypertension and increased plasma triglyceride levels, in the pre-menopausal period, were risk factors for future asymptomatic increased ET.Item Study on age-ralated variation in ovarian volume and proportion of endometrial thickness abnormalities in women of advanced and post-reproductive age(Wiley Publishing, 2016) Pieris, V.; Dias, T.; Palihawadana, T.S.; de Silva, J.OBJECTIVES : To describe the variations in endometrial thickness and the ovarian volume among peri and postmenopausal women. METHODS : A cross-sectional analysis was done in a study population of a longitudinal study. This was a community-based study and included 888 women randomly selected from the Ragama, Sri Lanka. This was done as part of a larger ongoing study, the “Ragama Health Study”. All study participants underwent a transvaginal pelvic ultrasound scan and the endometrial thickness and the ovarian size were measured. The ovarian volume was calculated using the formula for a prolate ellipsoid (0.523 h x w x l). RESULTS: The mean age of the study population was 59.45 yrs (SD=7.601) and 85.8% (n = 762) of them had undergone menopause. The prevalence of an endometrial thickness (ET) > 10 mm among premenopausal women was 14.98% while 0.9% (n = 1) had an ET>15 mm. Among postmenopausal women an ET >4 mm was seen in 16.01%. This included 1.3% (n = 10) who had an ET >10 mm. The mean of average ovarian volumes of the study population, according to age is shown in the figure. CONCLUSIONS : The study demonsatrated the proportion of asymptomatic women with a thickened endometrium among perimenoausal and poatmenopausal women (>15 mm and >4 mm resepectively) that necessitate evaluation is around 1%. It also described the age related changes in ovarian volume.
