Circulating carotenoids are associated with favorable lipid and fatty acid profiles in an older population at high cardiovascular risk.

Carotenoid intake has been reported to be associated with improved cardiovascular health, but there is little information on actual plasma concentrations of these compounds as biomarkers of cardiometabolic risk. The objective was to investigate the association between circulating plasma carotenoids and different cardiometabolic risk factors and the plasma fatty acid profile. This is a cross-sectional evaluation of baseline data conducted in a subcohort (106 women and 124 men) of an ongoing multi-factorial lifestyle trial for primary cardiovascular prevention.

Psychometric properties of the Weight Locus of Control Scale (MWLCS): study with Spanish individuals of different anthropometric nutritional status.

Introduction: The Multidimensional Weight Locus of Control Scale (MWLCS) measures a person's beliefs regarding the locus of control or lack of locus of control over his/her body weight.

Purpose: We aim to evaluate the factorial structure and psychometric properties of the MWLCS with Spanish normal weight, overweight and obese samples.

Methods: The research was carried out in two different studies.

Mediterranean alcohol-drinking pattern, low to moderate alcohol intake and risk of atrial fibrillation in the PREDIMED study.

Background And Aims: There is ongoing controversy about the effect of a low to moderate alcohol consumption on atrial fibrillation (AF). Our aim is to assess the association between adherence to a Mediterranean alcohol drinking pattern and AF incidence.

Methods And Results: A total 6527 out of the 7447 participants in the PREDIMED trial met our inclusion criteria.

Longitudinal changes in Mediterranean diet and transition between different obesity phenotypes.

Background & Aims: Little is known about the impact of specific dietary patterns on the development of obesity phenotypes. We aimed to determine the association of longitudinal changes in adherence to the traditional Mediterranean diet (MedDiet) with the transition between different obesity phenotypes.

Methods: Data of 5801 older men and women at high cardiovascular risk from PREDIMED trial were used.

Yogurt consumption and abdominal obesity reversion in the PREDIMED study.

Background And Aims: Evidence on the association yogurt consumption and obesity is not conclusive. The aim of this study was to prospectively evaluate the association between yogurt consumption, reversion of abdominal obesity status and waist circumference change in elderly.

Methods And Results: 4545 individuals at high cardiovascular risk were prospectively followed.

Mercury and methylmercury intake estimation due to seafood products for the Catalonian population (Spain).

This study estimates mercury and methylmercury levels in fish and fishery products commercialized in the city of Barcelona, Spain, from 2001 to 2007. Combining data of mercury levels in food with the consumption data of 2158 people (as the median of two 24-h recall), the total mercury intake of the Catalonian population was calculated. Mercury was detected in 32.

Compliance with the European and national nutritional objectives in a Mediterranean population.

Objective: To analyze compliance with the current European and Spanish nutritional objectives in a representative sample from Catalonia, a Spanish Mediterranean region; and to examine relationships between diet and plasma fatty acid composition.

Design: Cross-sectional nutritional survey.

Setting: Population based random sample derived from the Catalan Nutrition Survey.

Increasing serum levels of non-DDT-derivative organochlorine pesticides in the younger population of the Canary Islands (Spain).

Organochlorine pesticides are a lipophilic class of chemicals that persist in the environment and tend to accumulate in human tissues for years. They came into widespread use in the late 1940s. Because of their capacity to bioaccumulate and biomagnify in food chains and their toxic effects, most of them were banned in industrialized countries, among them Spain, in the late 1970s and 1980s.

Nontraditional nutrition education interventions: the radio ECCA method.

Objective: To evaluate a nutrition education intervention using a radio programme in the Canary Islands.

Design: Pre-post quasiexperimental epidemiological study.

Setting: Free living population in the Canary Islands, Spain.

Nutritional risks in the Spanish population: results of the eVe study.

Objective: To determine the vitamin status of different groups within the Spanish population.

Design: Pooled analysis of cross-sectional population nutritional regional studies and meta-analysis of smaller studies in population subgroups performed in Spain between 1990 and 1999.

Subjects: In total, 10 208 participants in eight random population studies aged 25-60 y and participants in 76 studies included in the meta-analysis.

Food preferences of Spanish children and young people: the enKid study.

Objective: To describe the profile of food preferences, likes and dislikes of Spanish children and young people and analyse its connection with prevailing food patterns.

Design: Cross-sectional population survey.

Setting: Population study.

Sociodemographic and lifestyle determinants of food patterns in Spanish children and adolescents: the enKid study.

Objective: To analyse prevailing food patterns among Spanish children and young people and their relationship to sociodemographic and lifestyle factors.

Design: Cross-sectional population survey.

Setting: Population study.

Nutrient adequacy and Mediterranean Diet in Spanish school children and adolescents.

Objective: To evaluate dietary habits and nutritional status of Spanish school children and adolescents, and their relationship with the Mediterranean Diet.

Design: Cross-sectional study by face-to-face interview.

Setting: Free living children and adolescents of all Spanish regions.

Olive oil and the Mediterranean diet: beyond the rhetoric.

Objective: The purpose of this study was to analyze the association of food, nutrient and energy intakes with olive oil consumption in Spain.

Design: Cross-sectional study by face-to-face interview.

Setting: Population-based random sample derived from the Catalan Nutrition Survey.

[Concentrations of Na, K, Ca, and P in serum from a representative sample of the Canary Islands population].

As part of the nutritional survey of the Canary Islands (ENCA-1998), the concentrations in serum of Na, K, Ca and P were determined in 395 individuals representing the population of the Canary Islands. The concentrations were found to be within the reference intervals described for the healthy population. Differences were observed in the mean concentrations depending on the island of residence.

Population attitudes towards changing dietary habits and reliance on general practitioners in Spain.

Objective: To investigate the relationship between population attitudes towards modifying food behaviour and reliance on General Practitioners (GPs) as nutrition educators.

Design: Personal interview in a random sample of the general population of the Canary Islands as part of the Canary Islands Nutrition Survey.

Subjects: 1747 individuals aged 6-74y.
