The Effect of Vitamin E Supplementation on Lipid Profiles and Adiponectin Levels in Obese Adolescents: A Randomized Controlled Trial

Background: low-grade chronic inflammation in obese individuals contributes to the development of lipid abnormality and insulin resistance. Vitamin E has antioxidant and insulin-sensitizing properties, mediated by adiponectin. In this study, we aimed to evaluate the effect of vitamin E supplementation on lipid profiles and adiponectin levels in obese adolescents. Methods: this was a randomized, double-blind, controlled study. Obese adolescents aged 14-18 years, with no history of taking anti-obesity or antioxidant drugs, were recruited and randomized into two groups: vitamin E and placebo. The dose of vitamin E was 400 IU/day. Intervention was administered for two months. Lipid profiles and adiponectin levels were measured at baseline and after intervention. Primary outcomes were analyzed using the per-protocol analysis principle. Statistical analysis was performed using the independent t-test or the Mann-Whitney U test. Results: a total of 66 subjects completed the intervention study, 34 in the vitamin E group and 32 in the placebo group. Lipid profiles and adiponectin levels at 2 months after intervention did not differ significantly between the two groups. Changes from the baseline level were also not significantly different between the two groups and were inconsistent from one subject to another. Conclusion: in obese adolescents, vitamin E supplementation of 400 IU/day for 2 months does not significantly affect lipid profiles and adiponectin levels

Hubungan antara Ukuran Lingkar Pinggang dengan Masa Lemak Tubuh, Profil Lipid, dan Gula Darah Puasa pada Remaja Obese

Latar belakang. Obesitas pada anak masih menjadi masalah dunia, termasuk Indonesia. Obesitas abdominal, yang ditandai dengan besarnya ukuran lingkar pinggang, dapat meningkatkan risiko penyakit kardiovaskular, metabolik, dan kematian. Tujuan. Penelitian ini bertujuan untuk mendapatkan gambaran ukuran lingkar pinggang pada anak obes, serta hubungannya dengan masa lemak tubuh, profil lipid, dan kadar gula darah puasa. Metode. Penelitian ini merupakan studi potong lintang. Subjek penelitian adalah anak usia 14-18 tahun dengan obesitas. Pemeriksaan tinggi badan, berat badan, lingkar lengan atas, lingkar pinggang, dan bioelectric impedance analyzer (BIA) dilakukan untuk memperoleh gambaran antropometri subjek. Pemeriksaan darah puasa dilakukan untuk memperoleh data profil lipid dan gula darah puasa. Hasil. Sebanyak 69 subjek terlibat dalam penelitian ini. Semua subjek mempunyai lingkar pinggang ≥P80, dengan lingkar pinggang terlebar adalah 138 cm.

Detection of childhood developmental disorders, behavioral disorders, and depression in a post-earthquake setting

Background Disasters, including earthquakes, may strike abruptly without warning. Children may develop psychological damage resulting from experiencing an overwhelmingly traumatic event. They may feel very frightened during a disaster and demonstrate emotional and behavioral problems afterwards. Objective To evaluate the presence of developmental disorders, behavioral disorders, and depression in children after the earthquake at Padang and Pariaman on September 30th, 2009. Methods This was a crosssectional study using the developmental pre screening questionnaire (KPSP), Pediatric Symptoms Checklist-17 (PSC-17), and Child Depression Inventory (CDI) in children after the Padang and Pariaman earthquake (September 30th, 2009), in Sungai Limau and Sungai Geringging District, Pariaman Region, West Sumatera. Our study was conducted October 15th to November 28th, 2009. Results There were 172 children screened using the KPSP. Forty-two (25%) children scored 78 (reason for concern), 18 (10%) children scored <7 (suspected to have a developmental disorder), and the remainder scored as developmentally appropriate. Behavioral disorder screening was perfonned in 339 children using the PSC 17. Internalizing disorder alone was suspected in 58 (17%) children, externalizing disorder alone in 26 (7.7%), and attentiondefidt disorder alone in 5 (1.5%). Eight (2.4%) children were suspected to have both internalizing and attentiondefidt disorders, 4 (1.2%) children externalizing and attentiondefidt disorders, 22 (6.5%) children internalizing and externalizing disorders, and 15 (4.4%) children all three disorders. From 4 9 children who underwent depression screening using CDI, 15 (30.6%) children were suspected to have depression.  Conclusion After the Padang and Pariaman earthquake, we found 10% of subjects screened were suspected of having a developmental disorder. The most connnonbehavioral disorder found was internalizing disorder. Possible depression was found in 30.6% of children surveyed. Traumatized children are at risk for developing post traumatic stress disorder.  2011;5' :133-7]
