Obesity is becoming an epidemic globally as it has been closely linked with a wide variety of chronic diseases. The identification of associated factors for obesity occurrences is still the main interest of many researchers. However, there has been extensive disagreement among researchers over possible factors associated with obesity which commonly involve the demographic factors, socioeconomic status (SES) and environmental factors. Biomarkers are also considered as important possible factors linked with the prevalence of obesity but investigations looking into their associations are still lacking. Therefore, it is important to examine factors that are associated with obesity using biomarkers and common factors to get detailed perspectives on obesity prevalence. The objectives of this study are to determine the prevalence of obesity and to examine the association between the common factors and biomarkers with obesity among community in Selangor, Malaysia. The results showed that the prevalence of obesity among participants was 49% (N=498) and Ordinal regression model with Cauchit built-in link function was the best fitted model to predict obesity. Meanwhile, three types of common factors (i.e. older age, being female and Malay ethnic) and one type of biomarker (i.e. high glucose level) were found to be significantly associated with obesity.
This study evaluate the Lee-Carter model for projecting age and gender specific mortality rates and life expectancy at births Thailand and Singapore. Although the Lee many developed countries, little information is obtained on the suitability of the model for developing countries. We fit age and gender specific mo country from 1960 to 1989 into the model and forecast over the evaluation period from 1990 to 2015. The forecast values are then compared with actual rates over the same period to estimate the out-sample forecast errors. Th that the Lee-Carter model works better in Malaysia, Indonesia and Thailand, than in Singapore. In terms of life expectancy at births, the Lee accurate for females than that of males.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
