Abstract: The elemental compositions and concentration of major and minor trace elements of twenty (20) tropical hardwoods from the environmental site of Pra Anum forest (longitudes 1o 12’ and 1o 15’ W; latitude 6o 14’ and 6o 20’ N) were determined using Instrumental Neutron Activation Analysis (INAA). The investigation covered samples from the immediate vicinity of the soil in which the woods were grown, the root, stem and the leaf segments of the wood species. A total of seven major trace elements (Al, Mg, Ca, K, Na, Cl, Na) and two minor trace elements (Br, La) were identified. The concentrations of all the elements were found to be generally highest in the leaves (> 10,000 ppm) of all the wood species. Ca and K were found in highest concentration levels in the stem (> 500 ppm) of the wood species, Albizia zygia, Morinda lucida and Stromboria glaucescens. In the root, Ca and K were found comparatively high (> 500 ppm) in Daniellia ogeafaro, Albizia zygia, Morinda lucida and Stromboria glaucescens. There were anomalous cases of certain wood species having greater concentrations of trace elements in their parts than that measured in the soils. The concentrations of Ca in Albizia zygia and Morinda lucida were found to be on the average, constant for the roots, stems and leaves.

Abstract: Introduction: Waist circumference (WC) in children or teenage have a close relation with the prediction to cardiovascular disease and diabetes mellitus type 2. The person that have a high risk is the children with WC percentile <90 which direct us to a study about the relation of waist circumference and lipid profile in children as an early intervention of prevention of cardiovascular disease in children. Methods: We have done a cross sectional study about the relationship of the waist circumference and lipid profile in children. The study samples are the junior high schools of Nusantara’s, Frater’s, and Islamic Athirah’s that met the criteria. The study was done from July 2012 until January 2013. Results: The study samples that met the study criteria are 86 children with 43 of them are with WC percentile >90 and the rest of 43 with percentile <90. By a multivariate analyses, we obtained 3 variables of lipid profile that have a relation to the WC percentile >90, which a cholesterol level total AOR is 12.621 (95% CI 3.72-94.40), triglyceride is AOR 6.945 (95% CI 1.80-54.67) and the ratio of LDL and HDL cholesterol with AOR 4.025 (95% CI 1.03-17.48). Conclusion: According to the study result, we conclude that the cholesterol frequency occurrence is high; the triglyceride is also high, and the ratio of high LDL and HDL cholesterol are more greats in WC children with percentile >90 rather than the percentile <90.
