Abdominal Obesity and Its Associated Factors Among Malaysian Women, Does Ethnicity Matter?
No full textIntroduction Generally, a cause of death and disability were contributed by an excess of body fat. For health, the issue is not how much you weigh, but how much abdominal fat you have. This study aims to determine the prevalence of abdominal obesity among Malaysian women and its association with sociodemographic and personal life style.
Methodology Data were obtained from the National Health and Morbidity Survey (NHMS) 2019 which was carried out via face-to-face interviews using mobile devices. Abdominal obesity was defined according to WHO/IASO/IOTF, 2000 Waist Circumference cut-off (>= 90cm for Men, >= 80cm for Women). A complex sample analysis was carried out at 95% confidence interval using SPSS version 21.0.
Results The prevalence of abdominal obesity among women was 64.8% (95% CI: 62.62, 66.94). Ethnic Malays with age 60 years and above have the highest rate of abdominal obesity compared to other groups. Higher abdominal obesity was found in rural area, age 40-59 years old, unemployed, B40 income group and inactive physical activity for Sarawakians. Logistic regression analysis found that women at risk of having abdominal obesity in Malaysia were those of older people [aOR: 3.464 (95% CI: 2.460 - 4.879)], Sarawakians [aOR: 3.682 (95% CI: 2.222 - 6.102)] and no formal education [aOR: 1.354 (95% CI: 1.052 - 1.742)].
Discussion NHMS 2019 revealed that abdominal obesity was higher among women compared to male. Therefore, health education programs should provide information about the risk factors for abdominal obesity to all women, and preventive strategies should be implemented accordingly.

Revisión exploratoria de la composición fitoquímica y las actividades biológicas asociadas de varias especies del género caulerpa y su potencial en la industria farmacéutica
No full textEn la actualidad, gran parte de los medicamentos se obtienen a partir de compuestos aislados de seres vivos. Ante esta perspectiva, existe un interés creciente en la búsqueda de nuevos compuestos bioactivos, especialmente en organismos que han sido poco explora-dos hasta ahora, como es el caso de algunas especies de algas marinas. Este trabajo pretendió caracterizar fitoquímicamente e identificar las aplicaciones y beneficios procedentes de los metabolitos secundarios del género Caulerpa. Para llevar a cabo este estudio, Se realizó una revisión exploratoria con enfoque sistemático de artículos científicos en las bases de datos Scopus, PubMed, Marine Drugs, Scielo y Lilacs. El análisis de la información recopilada fue apoyado por el programa Microsoft Excel® y el gestor bibliográfico Zotero®. Se identificó el potencial bio prospectivo de las actividades biológicas de compuestos asociados a especies del género Caulerpa y su impacto en la industria farmacéutica a través de la revisión de 93 artículos científicos. Los hallazgos resaltan la importancia composicional y funcional de los polisacáridos sulfatados, los metabolitos secundarios Caulerpenina y Caulerpina, así como los ácidos grasos y extractos de Caulerpa, debido a que han revelado diversas actividades biológicas, incluyendo el potencial antiinflamatorio, antimicrobiano, antitumoral y antioxidante. La presencia de especies del género Caulerpa en el Caribe colombiano, respaldada por datos de caracterización de diversidad algal a nivel nacional, sugiere un potencial significativo de los recursos subvalorados de Caulerpa en Colombia para su desarrollo a mediano y largo plazo en la industria farmacológica. Universidad Libre Seccional Barranquilla -- Facultad de Ciencias Exactas y Naturales -- Programa de MicrobiologíaCurrently, a significant percentage of medicines derived from compounds isolated from living organisms. Considering this perspective, the exploration of new bioactive compounds is inclined to those organisms that have remained unexplored, as occurs with some species of marine algae. This work aimed to phytochemically characterize and identify the applications and benefits from the secondary metabolites of the Caulerpa genus. To conduct this study, an exploratory review of scientific articles was carried out using a systematic approach on databases including Scopus, Pubmed, Marine Drugs, Scielo and Lilacs. The collected information was analyzed using Microsoft Excel® and the reference management software Zotero®. Through the review of 93 scientific articles, the bioprospective potential of biologically active compounds associated with Caulerpa spp. And their impact on the pharmaceutical industry was identified. The findings highlight the compositional and functional importance of sulfated polysaccharides, as well as the secondar y metabolites Caulerpin and Caulerpenyne, along with the fatty acids and extracts of Caulerpa, since these compounds have demonstrated diverse biological activities, including anti-inflammatory, antitumoral, antimicrobial and antioxidant potentials. The presence of Caulerpa spp in the Colombian Caribbean, supported by data on algal diversity at the national level, suggests a significant potential for underexplored resources from Caulerpa in Colombia. These resources hold promise for medium and long-term development in the pharmaceutical industry
