A cross-sectional survey combined with 24-hour dietary recall and food diary was undertaken to assess the calcium intake of the Myanmar population. The study was conducted from November 2003 to October 2005. A total of 886 subjects of both sexes aged above 2 years from three States and Divisions (Bago, Kayin, and Yangon) of Myanmar were included in the study. The major measures were mean daily calcium intake (mg/day) and major sources of calcium in the diet. Overall mean calcium intake was 197+13mg/day (2-9 years), 421+2mg/day (10-19 years), 399+21 mg/day (20-49 years), and 383+25mg/day (>50 years) for males, while the corresponding values for females were 207+17 mg/day, 366+19 mg/day, 387+16 mg/day, and 327 +19 mg/day. Calcium intake was less than 80% of the recommended dietary allowances (RDA) for Myanmar for ages 2-9 years and 10-29 years in all the study areas, and for the 50 years and above age group in Yangon. Fish paste was found to be the major source of calcium. Milk and milk products contributed very little to total calcium intake, contributing 2.1% for residents in Yangon, 5.1% in Pa-an and none in Bago. Consumption of calciumrich foods, particularly milk and milk products, should be encouraged among the Myanmar people. Towards this end, appropriate nutrition education materials should be developed for promotional purposes.

Objective: To assess the effect of oral calcium supplementation on lipid profile and atherogenic index of plasma (AIP). Methodology: This study was undertaken in 28 centrally obese male subjects [age 26.4 (6.5) years], BMI 31.6 (4.7) kg/m2, WC 99.4 (6.4) cm. All participants received six tablets of CaCO3 (250 mg of elemental calcium/ capsule, for a total of 1500 md/day) for 8 weeks. Serum lipid profile including triglyceride, total cholesterol, HDL-C, LDL- C was measured at baseline and after intervention. AIP was calculated by using formula = log (TG/HDL-C). Results: Oral calcium supplementation achieved a 22% (36 mg/dL, p<0.001) reduction in Triglyceride from baseline [163.4 (37.9) mg/dL] and 19.2% ( 5.8 mg/dL, p<0.001) increase in HDL-C from baseline [30.4 (7.4) mg/dL)]. There were no significant treatment effects on total cholesterol [217.1 (41.21) mg/dL vs 196.3 (46.2) mg/dL] and LDL-C [155.4 (45.1) mg/dL vs 136.3 (45.1) mg/dL]. Significant reduction in serum total cholesterol and LDL-C level was only found in dyslipidemic centrally obese subjects. AIP decreased significantly by 51% with calcium carbonate treatment [median and interquartile range; 0.35 (0.29-0.44) vs 0.17 (0.04-0.44), p<0.01]. Conclusion Eight-week calcium supplementation at 1500 mg/day led to a significant change in lipid levels and AIP.

Objective. This study determined the relationship between plasma adiponectin level and corrected QT interval (QTc) in smokers and non-smokers. Methodology.This cross-sectional analytical study was undertaken in 30 smokers and 30 non-smokers. Plasma adiponectin level was determined by enzyme-linked immunosorbent assay (ELISA). The QT interval was measured by routine 12-lead ECG with Lead II rhythm and QTc was calculated. Results. Mean plasma adiponectin level was significantly lower in smokers (27.89±15 μg/ml) than that of non-smokers (52.13±21.57μg/ml) (p<0.001). Mean QTc interval was significantly longer in smokers than that of non-smokers (415.37±29.9 versus 395.63±26.13 ms, p<0.01). Higher risk of low adiponectin level (odds ratio [OR],8.1; 95% confidence interval [CI],1.61-40.77) and QTc interval prolongation (OR,6; 95%CI,1.17-30.73) were observed in smokers. There was weak significant negative correlation between plasma adiponectin level and QTc interval in the study population (n=60, r=-0.407, p=0.001). Moreover, low plasma adiponectin level was significantly associated with prolonged QTc interval in the study population (n=60, Fisher's exact p value<0.05). Risk of QTc interval prolongation was 4.3 times higher in subjects with low plasma adiponectin level (OR,4.27; 95% CI,1.05-17.46). Conclusion. Smokers have greater risk for low plasma adiponectin level and prolonged QTc interval. There is a relationship between plasma adiponectin level and QTc interval.
