Spatial analysis of the relationship between mortality from cardiovascular and cerebrovascular disease and drinking water hardness

2004

Journal Article; Research Support, Non-U.S. Gov't; Reproduced with permission from Environmental Health Perspectives. Previously published scientific papers have reported a negative correlation between drinking water hardness and cardiovascular mortality. Some ecologic and case-control studies suggest the protective effect of calcium and magnesium concentration in drinking water. In this article we present an analysis of this protective relationship in 538 municipalities of Comunidad Valenciana (Spain) from 1991-1998. We used the Spanish version of the Rapid Inquiry Facility (RIF) developed under the European Environment and Health Information System (EUROHEIS) research project. The strateg…

A high dietary glycemic index increases total mortality in a Mediterranean population at high cardiovascular risk

2014

© 2014 Castro-Quezada et al. Objective: Different types of carbohydrates have diverse glycemic response, thus glycemic index (GI) and glycemic load (GL) are used to assess this variation. The impact of dietary GI and GL in all-cause mortality is unknown. The objective of this study was to estimate the association between dietary GI and GL and risk of all-cause mortality in the PREDIMED study. Material and Methods: The PREDIMED study is a randomized nutritional intervention trial for primary cardiovascular prevention based on community-dwelling men and women at high risk of cardiovascular disease. Dietary information was collected at baseline and yearly using a validated 137-item food freque…

Lifestyles and risk factors associated with adherence to the Mediterranean diet: a baseline assessment of the PREDIMED trial

2013

Background: The traditional Mediterranean dietary pattern (MedDiet) is associated with longevity and low rates of cardiovascular disease (CVD). However, there is little information on who is more likely to follow this food pattern. Aim: To evaluate how different factors are associated with lower MedDiet adherence in older Spanish subjects. Methods: We included 7305 participants (men aged 55-80 y, women 60-80 y) at high-risk of CVD recruited into the PREDIMED trial (ISRCTN35739639). Socioeconomic, anthropometric, lifestyle characteristics and CVD risk factors were recorded. A validated 14-item questionnaire was used to evaluate MedDiet adherence at baseline. Multivariate models were used to …

A 14-item Mediterranean diet assessment tool and obesity indexes among high-risk subjects: the PREDIMED trial

2012

Objective Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet) is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circum…

Incidence of Stakeholders in the corporate social responsibility of micro, small and medium-sized enterprises of Santa Marta

2018

Abstract This article analyses the perception and application of corporate social responsibility (CSR) practices in a sample of 499 micro, small and medium enterprises (MSMEs) in the city of Santa Marta (Colombia) following the theory of Stakeholders. Specifically, the interdependence technique of exploratory factor analysis was used to determine the most influential Stakeholders in the execution of CSR practices. It was found that Stakeholders related to the value chain, the environment and corporate management favour social responsibility actions in local MSMEs. In contrast, community and government have less influence on the development of social responsibility practices in MSMEs. Additi…

Cross‐national validation of the Social Media Disorder‐scale : Findings from adolescents from 44 countries

2022

Background and aims There is currently no cross-national validation of a scale that measures problematic social media use (SMU). The present study investigated and compared the psychometric properties of the Social Media Disorder (SMD)-scale among young adolescents from different countries. Design Validation study. Setting and participants Data came from 222,532 adolescents from 44 countries participating in the Health Behaviour in School-aged Children (HBSC) survey (2017/2018). The HBSC survey was conducted in the European region and Canada. Participants were on average 13.5 years old (SD = 1.6) and 51.2% were girls. Measurement Problematic SMU was measured using the 9-item SMD-scale with …

Adolescent use of social media and associations with sleep patterns across 18 European and North American countries

2023

Objective Over the past decade, concurrent with increasing social media use (SMU), there has been a shift toward poorer sleep among adolescents in many countries. The purpose of this study was to examine the cross-national associations between adolescent SMU and sleep patterns, by comparing 4 different categories of SMU (nonactive, active, intense, and problematic use). Design, setting, and participants Data were from 86,542 adolescents in 18 European and North American countries that participated in the 2017/18 Health Behaviour in School-aged study. Measurements Mixed-effects linear regression models were used to examine cross-national associations between 4 SMU categories and adolescent s…

International perspectives on social media use among adolescents: Implications for mental and social well-being and substance use

2022

In the present study, we aimed to explore the relationship between intensity of social media use (SMU), problematic SMU and well-being outcomes. Four categories of SMU were developed taking into account both intensity of use and problematic SMU simultaneously: non-active; active; intense; and problematic use. Using these four categories, we assessed associations between SMU and mental and social well-being, and substance use. Data from 190,089 respondents aged 11, 13, and 15 years from 42 countries involved in the Health Behavior in School-aged Children (HBSC) study were analyzed. With a slight cross-national variance, 78% of adolescents in the sample were classified as active or intense us…

3d mesh denoising using normal based myriad filter

2011

We propose a new filtering scheme for denoising of 3D objects which are represented by a triangular mesh. This scheme consists on applying myriad filter to face normals and then updating the vertices positions in order to preserve the original shape of the object. The choice of the Myriad is justified by the assumption of Cauchy distributed angles between surface normals. This filter improves the performance of a normal-based method which is adapted to the underlying mesh structure. To evaluate these methods of filtering, we use three error metrics. The first is based on the vertices, the second is based on the normals and the third is based on Hausdorff distance. Experimental results demon…
