Background: The World Health Organization (WHO-2007) and the International Obesity Task Force (IOTF-Cole) systems assess child weight status. However, derived estimations often differ. We aimed to a) compare the prevalence of overweight and obesity, b) analyze individual and contextual factors associated with child weight using multilevel analysis and c) explore the spatial distribution of overweight and obesity using both classification systems. Methods: We used data from the 2015/2016 National School Height and Weight Census in El Salvador. Information on 111,991 children aged 6.0-9.9 years attending the first grade was analyzed. Body mass index Z-score (BMIZ), overweight and obesity were defined with both classification systems. Weighted kappa was used to measure agreement. Child, school and municipal potential determinants of BMIZ were examined by multilevel analysis. Municipal spatial clustering of overweight and obesity was tested using Moran's Index and Getis-ord Gi* statistics. Results: The combined prevalence of overweight and obesity was higher according to the WHO system than the IOTF (30.4% vs 23.1%). The weighted kappa was 0.83. Boys, children attending urban schools, children attending private schools, and children residing in municipalities with high human development index had higher BMIZ than their counterparts. The Moran's indexes were positives and significant. Clusters of high prevalence (above the national prevalence) of overweight and obesity were found in 29 municipalities using the WHO and IOTF systems. For obesity, 28 and 23 municipalities in clusters of high prevalence were detected using the WHO and IOTF criteria, respectively. Conclusions: Overweight and obesity is high among school-age children in El Salvador. The prevalence of overweight and obesity was higher when using the WHO system, as compared to the IOTF system. Irrespective of the classification system, the multilevel and spatial analysis derived similar interpretations. These results support the need for national preventive interventions with targeting strategies to reduce overweight and obesity in school-age children.
The present study allows end-userś opinions on the utility of the various products/services offered by HTA agencies to be contrasted in order to adapt HTA activity to their needs and requirements. The involvement of health care professionals in all HTA fields is perceived as one of the main lines of action for HTA agencies. Such involvement could be achieved by reinforcing personal contact and increasing feedback to collaborators.
The erectile dysfunction is a pathology that, with different degrees of intensity, affects nearly the 20% of the spanish adult men. The treatment is usually performed in stages, reserving the penile prosthesis for when other previous treatments have failed. The aim of this work is to evaluate, according to the state of present knowledge, the effectiveness and security of the penile prosthesis for the treatment of the erectile dysfunction. With this purpose 52 articles were selected, observing a 5 years prosthesis survival of 78-91% and a 3-8% of surgical complications. Mechanical failures and infection percentages were smaller in the semi-rigid prosthesis that in the inflatable ones, with high levels of postoperative satisfaction in patients as well as in their couples, even greater than in other treatments available at the present time. The penile prosthesis implantation must be reserved for the organic erectile dysfunction when previous treatments have failed, evaluating the risk-benefit relation and informing the patient of the results that are hoped to be obtained and of the possible complications that can arise. In view of the great concern of our society with the erectile function and the availability of effective drugs, an increase in the demand of penile prosthesis implantation is predictable in those patients highly motivated, but refractory to the less invasive treatments.
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.
