Item Contribution of physical activity and sedentary behaviour to glycaemic status in urban women(Sri Lanka Medical Assosiation, 2012) Waidyatilaka, P.H.I.U.; de Silva, A.; Lanerolle, P.; Wickremasinghe, R.; Somasundaram, N.; Atukorala, S.INTRODUCTION: Physical activity plays a significant role in the development of Type 2 diabetes mellitus and the role of sedentary behaviour is gaining importance. This association may exist even in persons meeting exercise guidelines. AIMS: To assess percentage fat mass (FM%), waist circumference (WC), physical activity (PA) and sedentary behaviour (sitting time) in relation to glycaemic status in urban women. METHODS: Newly diagnosed diabetic and non diabetic urban women (30-45 years) were recruited in a community based cross sectional study following screening using fasting blood sugar (n-425). HbAlc was used to categorise "worn en as normoglycaemic (n=182) or dysglycaemic (n=243). PA and sitting time were assessed by the International Physical Activity Questionnaire (IPAQ). WC was measured and FM% was determined by Bio-impedance analysis. Means were used to describe variables and Spearman correlation coefficients and multiple linear regression analysis were used to test for associations. Results: Mean age of women was 37.7+4.0 years. Compared with normoglycemics, dysglycaemics had significantly higher WC(70.7±7.1 vs 80.7±7.5cm), FM% (32.0±5.6 vs 37.0±4.7%), and sitting time (144±66 vs 311±120 minutes/day)(p<0.001 for each variable). PA (7252±2935 vs 2769±1762METminutes/week) was significantly lower (p<0.001) in dysglycemics. WC(rs=0.575, p<0.001), sitting time (rs=0.712, p<0.001) were significantly correlated with HbAlc. PA (rs=- 0.719, p<0.001) was negatively correlated with HbAlc. WC and sitting time were significantly associated with glycaemic status (F=69.3, p<0.001) after adjusting for PA. CONCLUSIONS: WC, sitting time and PA are significantly associated with glycaemic status. Independent of PA, WC and sedentary behaviour are associated with dysglycaemia.Item Knowledge, attitudes and practices regarding type 2 diabetes mellitus, nutrition and lifestyle in urban Sri Lankan women(Sri Lanka Medical Association, 2013) Waidyatilaka, P.H.I.U.; de Silva, A.; Atukorala, S.; Somasundaram, N.; Lanerolle, P.; Wickramasinghe, R.AIMS: Data on population specific patterns of knowledge, attitudes and practices (KAP) is essential for the design of effective intervention strategies. The aim of this study was to assess KAP regarding type 2 diabetes mellitus (T2DM), nutrition and lifestyle in Sri Lankan urban women who were unaware of their glycaemic status. Methods: 2800 apparently healthy urban women (30 - 45 years) were screened for dysglycaemia and 345 normoglcaemics and 272 dysglycaemics were selected from Coiombo Municipal Council area by random cluster sampling for a cross sectional study. An interviewer administered questionnaire was used to obtain KAP, demographic information and family history. Chi square test and Student's t- tests were used for categorical variables and for group comparison respectively. RESULTS: KAP on T2DM, nutrition and healthy lifestyle were poor. Knowledge on pre-diabetes and prevention of T2DM was also poor. However majority wanted to improve their knowledge. Women with a family history had better knowledge (p< 0.001) and attitudes (p< 0.05), but lower practice scores (p< 0.05) compared to women without a family history of T2DM. A significant (p< 0.001) proportion of women with a family history of T2DM found it difficult to resist eating foods high in fat and sugar. CONCLUSIONS: Overall KAP was poor, especially about pre-diabetes and prevention. Willingness to learn can be used positively to direct future interventions. Poor practices despite better knowledge and attitudes among women with a family history of T2DM indicate a need for targeted intervention.Item Measures of body fat in diabetic and non-diabetic females(Sri Lanka Medical Association, 2011) Waidyatilaka, P.H.I.U.; de Silva, A.; Lanerolle, P.; Wickremasinghe, R.; Somasundaram, N.; Atukorala, S.INTRODUCTION AND OBJECTIVES: Increased body fat (BF) predisposes to obesity linked co-morbidities, including diabetes. Data on body fat percentage in Sri Lankan adult populations are limited. Aim of this study was to assess %BF, waist circumference (WC) and body mass index (BMI) in adult diabetic, pre-diabetic and normoglycaemic females. METHODS: Free living females (n=25) aged 30-45 years, without any known illness, and 19 females of similar age, social class and employment, recently diagnosed with DM and yet untreated, were recruited from primary health care centers in Colombo Municipality for a community based cross sectional study. Weight, height and WC were measured using standard protocols and BMI calculated. Bio-impedance analysis was used to determine % BF. HbAlc was estimated and women grouped into diabetic (HbAlc >6.5 %), pre-diabetic (HbAlc 5.7-6.4 %) or normoglycemic categories. Results: Mean age of women was 36.6±4.1 years. In the group without known illness, 9 were pre-diabetic and 16 were normoglycaemic. No significant differences were observed between diabetic, pre-diabetic and normoglycaemic women in age or weight. There was no significant difference in BMI between diabetic (25.3±3.3kg/m), pre-diabetic (26.8±2.5 kg/m2) or normoglycaemic (24.4±3.7 kg/m2) women. However, %BF was significantly higher (p < 0.01) among diabetic (37.3± 6.1} and pre-diabetic (33.9±5.5) than in normoglycaemic women (28.6±9.9). WC was also significantly higher (p < 0.01) among diabetic (83.5±7.9 cm.) and pre-diabetics (84.5±6.8) than normoglycaemic women (76.2±6.4 cm). CONCLUSIONS: In this population, although there was no difference in BMI, pre-diabetic and diabetic women had a higher %BF and WC than normogiycaemics. Funded by IAEA.
