Abstract
The incidence of cardiovascular disease (CVD) is increasing in HIV-infected people. Risk factors such as hyperlipidemia, impaired glucose tolerance, and insulin resistance have become common. CVD in HIV may also be related to nontraditional risk factors including accumulation of visceral fat, inflammation secondary to HIV, and effects of some antiretroviral drugs. This cross-sectional study described the CVD risk factors of 123 adults living with HIV and calculated the 10-year estimate for general cardiovascular risk score. Results showed that approximately 25% of the participants were considered to be at high risk for developing CVD in the next 10 years. Increased waist circumference and longer duration of smoking habit were associated with elevated general cardiovascular risk scores. Similar to the general population, most of the identified risks could be modified through lifestyle management.

Abstract
Identifying sources of variability in the response to cancer chemotherapy requires knowledge of all variables, including concomitant medications, that can alter the metabolism and pharmacokinetics of chemotherapy. This study investigated the accuracy of the lists of concomitant medications in the charts of cancer patients. Information collated from a questionnaire, patient interview, and the patient's medical chart was used to obtain validated medication lists. Patients took an average of 4.8 prescription drugs, 1.6 nonprescription drugs, and 1.6 other remedies within the 3 days prior to chemotherapy. Of the concomitant drugs actually taken, the medical records did not report 24% of prescription drugs, 84% of nonprescription drugs, and 83% of other remedies. Electronic medical records (EMRs) were more complete than paper charts, but even these omitted >75% of nonprescription drugs and other remedies. Potential drug interactions were noted in this study. This study documents the extent and complexity of the concomitant drugs taken by patients undergoing chemotherapy and the deficiencies in recording this information in medical charts.

Abstract
OBJECTIVES Evidence of the effects of soft drinks consumption on BMI and lifestyle in adult populations is mixed and quite limited. The aim of the present study was to determine the association of soft drinks consumption with BMI and lifestyle in a representative Mediterranean population. DESIGN Two independent, population-based, cross-sectional (2000 and 2005) studies. Dietary intake was assessed using a validated FFQ. Weight and height were measured. SETTING Girona, Spain. SUBJECTS Random sample of the 35- to 74-year-old population (3910 men and 4285 women). RESULTS Less than half (41·7%) of the population consumed soft drinks; the mean consumption was 36·2 ml/d. The prevalence of sedentary lifestyle increased with the frequency of soft drinks consumption (P = 0·025). Daily soft drinks consumption significantly increased the risk of low adherence to the Mediterranean diet (OR = 0·57, 95% CI 0·44, 0·74 v. top tertile of Mediterranean diet score). Multiple linear regression analyses, controlled for potential confounders, revealed that an increment in soft drinks consumption of 100 ml was associated with a 0·21 kg/m² increase in BMI (P = 0·001). Only implausibly low reports of energy consumption showed a null association between soft drinks consumption and BMI. CONCLUSIONS Soft drinks consumption was not embedded in a healthy diet context and was positively associated with BMI and sedentary lifestyle in this Mediterranean population.

Abstract
Little data exists on metabolic syndrome (MetS) related with intake, especially for the South Korean. The purpose of this study was to develop and evaluate a food frequency questionnaire (FFQ) for nutritional assessment in the population with MetS in South Korea. Randomly selected female participants, mean age 21.9 years (n = 38) were invited to answer the FFQ twice (FFQ1 and FFQ2) over a nine-month interval and to complete twelve-day diet records (DR) during the months between in South Korea. The correlation coefficients for nutrient intake between FFQ1 and FFQ2 varied from 0.253 (niacin) to 0.573 (cholesterol), and the energy intake-adjusted correlation coefficients ranged from 0.187 for protein to 0.662 for iron. The energy intake-adjusted and de-attenuated correlation coefficients for comparison of FFQ1 and the DRs ranged between 0.277 (vitamin B1) and 0.768 (fiber), and between 0.229 (zinc) and 0.859 (fat) for comparison of DRs with FFQ2. The percentages of study subjects classified into the same quartiles in both the DRs and FFQ1 ranged from 15.8% (vitamin B6) to 47.4% (calcium), and for the same quartiles in DRs and FFQ2 from 13.2% (vitamin B1) to 44.7% (potassium). The FFQ has reasonably good validity and reproducibility. Further research is needed for an assessment of reproducibility and validation of present FFQ in the subjects with MetS.

Abstract
OBJECTIVE To evaluate the reproducibility of a semi-quantitative FFQ used in the Seguimiento Universidad de Navarra (SUN) project. DESIGN The data that were analysed were collected from an FFQ answered twice by a 326-participant subsample of the SUN project (115 men, 35.3 %; 211 women, 64.7 %), with either less than 1 year or more than 1 year between responses. The questionnaire included 136 items. Pearson correlation coefficients (r) were calculated to evaluate the magnitude of the association between both measures after energy adjustment and correcting for within-person variability. We also evaluated misclassification by quintiles distribution. RESULTS The highest corrected correlations among participants who answered before 1 year were found for PUFA (r = 0.99). Among participants who answered after 1 year between both questionnaires, olive oil had the highest corrected correlation (r = 0.99). The highest percentage of gross misclassification, lowest quintile in FFQ1 and highest quintile in FFQ2 or highest quintile in FFQ1 and lowest quintile in FFQ2 was for cereals, fish or seafood, and n-3 fatty acids (7.6 %). Alcoholic drinks had the highest percentage of reasonable classification, same or adjacent quintile, in FFQ1 and FFQ2 (86.4 %). CONCLUSIONS Our study suggests that FFQ reproducibility is acceptable for participants who answered the same questionnaire twice less than 1 year apart. Participants who answered FFQ more than 1 year apart showed worse values on reproducibility. We consider this Spanish FFQ as an important, valid and reproducible tool in nutritional epidemiology.

Abstract
INTRODUCTION Crohn's disease (CD) may lead to protein and calorie malnutrition (PCM) secondary to impaired digestive and absorptive functions of the small intestine and sometimes to the influence of diet taboos. The earlier the PCM is diagnosed, the higher are the odds of reversal. The objective of this study was to compare different methods of nutritional assessment in patients with CD and correlate them with the disease characteristics. SAMPLE The sample comprised 75 patients with CD from the Gastroenterology Service at the Hospital de Clínicas de Porto Alegre; 37 were male, with a mean age of 38.2 years old (SD = 13.3). All patients had been in clinical remission (CDAI <150) for over 3 months. They were not receiving enteral or parenteral nutrition. The nutritional assessment was considered: body mass index (BMI), triceps skin fold (TSF), arm circumference (MAC), arm muscle circumference (MAMC), subjective global assessment (SGA), non-dominating handgrip strength (HGS) and food intake inquiries. RESULTS When comparing the different nutritional assessment methods, 26.7% of the patients were malnourished according to the MAC, 29.3% according to the MAMC, 18.7% according to the SGA, 6.7% according to the BMI, 37.3% according to the TSF and 73.3% according to the HGS. No statistically significant associations were found for disease location, its behavior, drugs utilized, ESR, CRP, age of patients and disease time with the nutritional state verified by HGS, TSF, MAMC and SGA. CONCLUSION The prevalence of malnutrition is significant in patients with CD, even in clinical remission. The BMI should not be used as reference in this population. The HGS detected a high prevalence of nutritional risk in patients with CD in remission. Studies are required that correlate it with more sensitive methods, for the patients' effective nutritional state assessment.

Abstract
BACKGROUND Epidemiologic studies have suggested that flavonoid intake plays a critical role in the prevention of coronary heart disease. Because atherosclerosis is considered a low-grade inflammatory disease, some feeding trials have analyzed the effects of cocoa (an important source of flavonoids) on inflammatory biomarkers, but the results have been controversial. OBJECTIVE The objective was to evaluate the effects of chronic cocoa consumption on cellular and serum biomarkers related to atherosclerosis in high-risk patients. DESIGN Forty-two high-risk volunteers (19 men and 23 women; mean +/- SD age: 69.7 +/- 11.5 y) were included in a randomized crossover feeding trial. All subjects received 40 g cocoa powder with 500 mL skim milk/d (C+M) or only 500 mL skim milk/d (M) for 4 wk. Before and after each intervention period, cellular and serum inflammatory biomarkers related to atherosclerosis were evaluated. RESULTS Adherence to the dietary protocol was excellent. No significant changes in the expression of adhesion molecules on T lymphocyte surfaces were found between the C+M and M groups. However, in monocytes, the expression of VLA-4, CD40, and CD36 was significantly lower (P = 0.005, 0.028, and 0.001, respectively) after C+M intake than after M intake. In addition, serum concentrations of the soluble endothelium-derived adhesion molecules P-selectin and intercellular adhesion molecule-1 were significantly lower (both P = 0.007) after C+M intake than after M intake. CONCLUSIONS These results suggest that the intake of cocoa polyphenols may modulate inflammatory mediators in patients at high risk of cardiovascular disease. These antiinflammatory effects may contribute to the overall benefits of cocoa consumption against atherosclerosis. This trial was registered in the Current Controlled Trials at London, International Standard Randomized Controlled Trial Number, at controlled-trials.com as ISRCTN75176807.

Abstract
BACKGROUND & AIMS Assessment of dietary intake using a 3-day dietary record may delay the management of undernutrition. Methods allowing a quick estimation of dietary intake are needed. We aimed to determine the feasibility of assessing dietary intake using two 10-point verbal (AVeS) and visual (AViS) analogue scales, to assess the correlations of both scales with energy intake, and to determine the accuracy of AVeS for assessing undernutrition. METHODS We prospectively recruited 114 patients undernourished or nutritionally at-risk in two French University Hospitals. Undernutrition was defined as a Nutritional Risk Index <97.5. AVeS and AViS were performed by one interviewer and mean daily energy intake was calculated from 3-day dietary records by one dietician. RESULTS The feasibility of AVeS and AViS was 98% and 96%, respectively. Both verbal and visual scales were statistically correlated with calculated energy intake (rho=0.66 and rho=0.74, P<0.0001), especially in undernourished patients (rho=0.82, P<0.0001, for AVeS). Sensitivity, specificity, positive and negative predictive values of an AVeS score less than 7 for assessing undernutrition were 57%, 81%, 86% and 46%, respectively. CONCLUSION AVeS and AViS could be used for a quick assessment of dietary intake in clinical practice, particularly in undernourished in-patients. Thus, both verbal and visual analogue scales could be particularly useful for the management of hospital undernutrition.

Abstract
BACKGROUND Cancer patients take medications for coexisting disease and self-medicate with over-the-counter drugs (OTCs). A complete analysis of the use of prescription drugs, OTCs, and supplements during cancer treatment has never been done. METHODS The study developed and validated a self-administered questionnaire on the use of concomitant medications by patients undergoing treatment with chemotherapy. The questionnaire listed 510 prescription medications, OTCs, and supplements (including vitamins, minerals, and herbs). Fifty-two subjects completed the questionnaire while visiting the infusion clinic to receive chemotherapy. On a subsequent visit the subjects brought their medications to the clinic and a pharmacist reviewed their completed questionnaire. RESULTS Ninety-six percent of the subjects reported taking prescription medications within 3 days prior to chemotherapy, 71% reported taking OTCs and 69% reported use of supplements. The subjects took an average of 5.5 (range 0-13) prescription drugs, 2.2 (0-20) OTCs, and 1.9 (0-11) supplements. Twenty-one drugs were each taken by at least 10% of the subjects. Acetaminophen was taken by 59.6% of the subjects. One subject reported taking five acetaminophen-containing drugs. The questionnaire's sensitivity was 92.0%, specificity 99.9%. CONCLUSION Within 3 days prior to chemotherapy, subjects took an average of 9.6 concomitant medications, many of which alter drug metabolism and or disposition. In clinical trials, multivariate analysis of all concomitant medications could add to clinically relevant data to identify drug interactions that negate or potentiate the efficacy of cancer treatment regimens. In some instances, apparent resistance of tumors to chemotherapy may be the result of drug interactions.

Abstract
PURPOSE The purpose of this study was to examine the differences in nutritional intake and body mass index (BMI) in HIV patients with chronic diarrhea via secondary analysis of patients' nutritional diaries. A secondary purpose was to evaluate the quality of diets against national dietary guidelines. DATA SOURCES Seventy-five ambulatory patients with HIV were included in this study. Patients were categorized using baseline BMI as normal weight (BMI 18.5-24.9 kg/m2), overweight (BMI 25.0-29.9 kg/m2), and obese (BMI >or=30.0 kg/m2). Seven-day nutritional diaries were used to estimate diet in terms of dietary fats, cholesterol, fiber, protein, and sugar. A one-way analysis of variance was conducted to evaluate the relationship between BMI and mean nutritional intake from fat, saturated fat, polyunsaturated fat, monounsaturated fat, cholesterol, fiber, and sugar. CONCLUSIONS 39.7% and 13.3% of participants were overweight and obese, respectively. The mean intake of fat, saturated fat, and cholesterol was higher than the recommended levels by the National Cholesterol Education Program (NCEP), while the mean intake of monounsaturated fat, polyunsaturated fat, and fiber was below the NCEP guideline. Although the results were not statistically different between groups, grams of fiber intake were lowest for individuals with BMI >or=30.0 kg/m2. IMPLICATIONS FOR PRACTICE Advanced practice nurses should encourage increased physical activity and healthy diets at each visit for individuals living with HIV. The continued use of nutritional supplements to boost weight should also be reviewed at each visit to prevent the consumption of unnecessary calories.

Abstract
BACKGROUND Studies on obesity and glycemic index (GI) or glycemic load (GL) have had inconsistent results, perhaps in part because of underreporting or to heterogeneous dietary patterns across food cultures. OBJECTIVES We examined associations between body mass index (BMI) and GI or GL in a Mediterranean population, accounting for underreporting. We also constructed dietary factors related to GI and GL to better understand food patterns related to these measures. DESIGN Cross-sectional data on 8195 Spanish adults aged 35-74 y were analyzed. A validated food-frequency questionnaire was used to estimate GI and GL, with glucose as the reference value. Reduced-rank regression was used to construct dietary patterns that explained variation in GI and GL. Multivariate linear regression was used to estimate associations between BMI and GI, GL, and their respective diet factors with and without adjusting for energy, which may lie on the causal pathway between glycemic quality and obesity. Effects of excluding underreporters (ratio of energy intake:basal metabolic rate < 1.20) were examined. RESULTS Food patterns underlying high GI differed substantially from those of high GL, with fruits, vegetables, and legumes related positively to GL but negatively to GI. After excluding underreporters, GL was negatively associated with BMI, adjusting for energy. GI was not associated with BMI in any model. CONCLUSIONS After adjusting for energy, GL was associated with reduced BMI in this Mediterranean population. Underreporting did not explain this inverse relation, which was observed among subjects with plausible intakes.

Abstract
The aim of the present study was to analyse the association between adherence to the Mediterranean diet and self-perceived mental and physical health function, controlled for confounding effects of age, smoking, BMI, alcohol consumption, educational level, leisure-time physical activity and the presence of chronic conditions. A random sample of the 35-74-year-old population (3910 men and 4285 women) of Gerona, Spain, was examined in 2000 and 2005 in two independent population-based cross-sectional surveys. Dietary intake was assessed using a validated FFQ. The Mediterranean diet score (MDS) was calculated according to tertile distribution of energy-adjusted food consumption considered characteristic for the Mediterranean region. Health-related quality of life was measured using the SF-12 questionnaire. Alcohol consumption, leisure-time physical activity and smoking habits were recorded. Weight and height were measured. Age-adjusted linear regression analysis revealed a significant (P < 0.01) direct association of the MDS with self-reported mental and physical health in both sexes. An increase of 5 units of the MDS was directly associated with changes of 0.74 and 1.15 units in men and women, respectively, in the mental component score after controlling for potential confounders. The age-adjusted direct association of the MDS with self-reported scoring of physical health remained stable after adjusting for several confounders in men but was attenuated in women. Adherence to the Mediterranean diet was associated with higher scoring for self-perceived health.

Abstract
Nutrient adequacy in the diet is of paramount importance to physical and mental health. The aim of this study was to characterize the dietary pattern associated with a low energy density diet and determine its nutrient adequacy in elderly men and women. The subjects were men (n = 1150) and women (n = 1094) >65 y, examined in 2 population-based cross-sectional surveys (2000 and 2005) in northeast Spain (Girona). Dietary data were recorded using a 165-item FFQ. Reduced rank regression (RRR) analysis was used to identify an energy density-associated dietary pattern. A nutrient adequacy score (NAS) and Mediterranean diet score (MDS) were computed to estimate the association of diet adequacy with energy density. The RRR-derived factor (dietary pattern) predicted 75.4% of the variance in energy density of the diet. Vegetables, fruits, legumes, cooked potatoes, and low-fat milk and yogurt were key to the low energy density of the diet. Higher proportions of men and women consuming low energy density diets met dietary recommendations for total fat, saturated fat, cholesterol, total fiber, vitamin C, vitamin E, thiamin, riboflavin, vitamin B-6, folate, calcium, and magnesium than their peers on high energy density diets. Multivariate linear regression analysis revealed an inverse association (P < 0.001) of the NAS and MDS with energy density and energy density-related patterns. A low energy density diet has a higher capacity to prevent nutrient deficiency, despite lower energy content, than a high energy density diet in the elderly population studied.

Abstract
Olive oil decreases the risk of CVD. This effect may be due to the fatty acid profile of the oil, but it may also be due to its antioxidant content which differs depending on the type of olive oil. In this study, the concentrations of oleic acid and antioxidants (phenolic compounds and vitamin E) in plasma and LDL were compared after consumption of three similar olive oils, but with differences in their phenolic content. Thirty healthy volunteers participated in a placebo-controlled, double-blind, crossover, randomized supplementation trial. Virgin, common, and refined olive oils were administered during three periods of 3 weeks separated by a 2-week washout period. Participants were requested to ingest a daily dose of 25 ml raw olive oil, distributed over the three meals of the day, during intervention periods. All three olive oils caused an increase in plasma and LDL oleic acid (P < 0·05) content. Olive oils rich in phenolic compounds led to an increase in phenolic compounds in LDL (P < 0·005). The concentration of phenolic compounds in LDL was directly correlated with the phenolic concentration in the olive oils. The increase in the phenolic content of LDL could account for the increase of the resistance of LDL to oxidation, and the decrease of thein vivooxidized LDL, observed in the frame of this trial. Our results support the hypothesis that a daily intake of virgin olive oil promotes protective LDL changes ahead of its oxidation.

Abstract
Background As the primary source of dietary vitamin C is fruit and to some extent vegetables, the plasma level of vitamin C has been considered a good surrogate or predictor of vitamin C intake by fruit and vegetable consumption. The purpose of this systematic review was to investigate the relationship between dietary vitamin C intakes measured by different dietary methods and plasma levels of vitamin C. Method We searched the literature up to May 2006 through the OVID interface: MEDLINE (from 1960) and EMBASE (from 1988). We also reviewed the reference lists in the articles, reviews, and textbooks retrieved. A total of 26 studies were selected and their results were combined using meta-analytic techniques with random-effect model approach. Results The overall result of this study showed a positive correlation coefficient between Food Frequency Questionnaire (FFQ) and biomarker (r = 0.35 for "both" genders, 0.39 for females, and 0.46 for males). Also the correlation between Dietary Recalls (DR)/diary and biomarker was 0.46 for "both" genders, 0.44 for females, and 0.36 for males. An overall correlation of 0.39 was found when using the weight record method. Adjusting for energy intake improved the observed correlation for FFQ from 0.31 to 0.41. In addition, we compared the correlation for smokers and non-smokers for both genders (FFQ: for non-smoker r = 0.45, adjusted for smoking r = 0.33). Conclusion Our findings show that FFQ and DR/diary have a moderate relationship with plasma vitamin C. The correlation may be affected/influenced by the presence of external factors such as vitamin bioavailability, absorption condition, stress and food processing and storage time, or by error in reporting vitamin C intake.

Abstract
BACKGROUND Moderate alcohol consumption is cardioprotective. The mechanism for this beneficial effect might be reduced inflammatory responses, as suggested by prospective studies and small clinical trials in men. No studies have evaluated the antiinflammatory effects of wine in women. OBJECTIVE We investigated whether low-dose intake of white and red wines has differential effects on inflammatory markers in women. DESIGN In a crossover study, we randomly assigned 35 healthy women to two 4-wk periods of 20 g ethanol/d as white or red wine, preceded by two 4-wk washout periods. Before and after interventions, we measured serum lipids, circulating inflammatory biomarkers, cellular adhesion molecules (CAMs), and adhesion of monocytes to stimulated endothelial cells. RESULTS HDL cholesterol increased, and the serum concentrations of high-sensitivity C-reactive protein, intercellular adhesion molecule-1, CD40L, and interleukin-6 decreased after either wine (P < 0.01, all). Vascular CAM-1 and E-selectin decreased (P < 0.01) only after red wine. CAM expression by mononuclear cells was blunted after either wine, with a greater suppressant effect of red wine. Enhanced adhesion of monocytes to stimulated endothelial cells was reduced by 51% (95% CI: -57%, -45%) after white wine and by 89% (95% CI: -96%, -82%) after red wine (P = 0.01 for between-wine differences). CONCLUSIONS Moderate wine consumption is associated with beneficial effects on various inflammatory pathways related to endothelial activation in women. Probably because of its higher polyphenol content, red wine shows superior antiinflammatory effects than does white wine. Reducing low-grade inflammation and endothelial activation may be another potential mechanism by which alcoholic beverages exert their cardioprotective effect.

Abstract
Atherosclerosis is considered a low-grade inflammatory disease. Polyphenol-rich alcoholic beverages (red wine) have shown a more pronounced antiinflammatory effect than polyphenol-free alcoholic beverages (gin). However, no studies to our knowledge have evaluated the antiinflammatory effects of alcoholic beverages with medium-level polyphenol content such as cava (sparkling wine). We enrolled 20 healthy men (aged 34 +/- 9 y) in a randomized crossover study to receive 30 g ethanol/d as cava or gin for 28 d. Before both interventions, subjects abstained from alcohol for 2 wk. Inflammatory biomarkers of atherosclerosis and expression of adhesion molecules on peripheral leukocytes were measured before and after each intervention. Likewise, dietary intake and exercise were also evaluated. Expression of lymphocyte function-associated antigen-1 (LFA-1), very late activation antigen-4 (VLA-4), Sialyl-Lewis(x) (SLe(x)), and CD40 on monocytes decreased after cava intake (all P < 0.05), whereas only SLe(x) was reduced after gin intake (P = 0.036). Circulating markers of atherosclerosis including vascular cell adhesion molecule-1, E-selectin, and P-selectin decreased after both interventions (all P < 0.05). High-sensitivity C-reactive protein, intercellular adhesion molecule-1 (ICAM-1), IL-6, monocyte chemoattractant protein-1 (MCP-1), and CD40L were diminished only after cava intake (all P < 0.05). The effects of cava on circulating CD40L, ICAM-1, and MCP-1, and monocyte surface expression of CD40, LFA-1, and VLA-4 were greater than those of gin (all P < 0.05). In conclusion, both cava and gin showed antiinflammatory properties; however, cava had a greater protective effect, probably due its polyphenol content.

Abstract
BACKGROUND The high energy content of alcohol makes its consumption a potential contributor to the obesity epidemic. AIM OF THE STUDY To determine whether alcohol consumption is a risk factor for abdominal obesity, taking into account energy underreporting. METHODS The subjects were Spanish men (n = 1491) and women (n = 1563) aged 25-74 years who were examined in 1999-2000, in a population-based cross-sectional survey in northeastern Spain (Girona). Dietary intake, including alcohol consumption, was assessed using a food frequency questionnaire. Anthropometric variables were measured. RESULTS The mean consumption of alcohol was 18.1 +/- 20.7 g/d in men and 5.3 +/- 10.4 g/d in women. 19.3% of men and 2.3% of women reported alcohol consumption of more than 3 drinks per day. The consumption of alcohol was directly associated with total energy intake in men (P < 0.001) and women (P = 0.001). The proportion of energy underreporting significantly (P < 0.001) decreased with higher amounts of alcohol drinking in both genders. Multiple logistic regression analysis, controlled for energy underreporting, smoking, educational level, leisure-time physical activity, energy, and diet quality, revealed that consuming more than 3 drinks of alcohol (>30 g ethanol) was significantly associated with the risk of abdominal obesity (Odds ratio 1.80; 1.05, 3.09) and exceeding recommended energy consumption (Odds ratio 1.97; 1.32, 2.93) in men. A very small number (2.13%) of women in this population reported high levels of alcohol consumption. CONCLUSIONS Alcohol consumption in elevated amounts was associated with risk of abdominal obesity in men, independent of energy underreporting.

Abstract
The aim of the present study was to describe the association of fast food consumption with BMI, energy intake and diet quality in a Mediterranean population. The subjects were Spanish men (n 1491) and women (n 1563) aged 25-74 years who were examined in 1999-2000, in a population-based cross-sectional survey in northeast Spain (Girona). Dietary intake was assessed using a FFQ that included four typical fast food items. Two dietary-quality indices, the Mediterranean diet score and the healthy eating index, were created. Height and weight were measured. Within the population studied, 10.1 % reported eating fast food at least once per month. Dietary energy intake and energy density were directly associated with frequency of fast food consumption. Multivariate logistic regression analysis adjusted for lifestyle and educational level showed an inverse association of frequency of fast food consumption with meeting the dietary reference intake (DRI) for energy (P = 0.001). The consumption of fast food more than once per week increased the risk of overall low diet quality (P < 0.001). BMI was directly associated with fast food consumption expressed in g/d (P = 0.025) and in kJ/d (P = 0.017). The risk of being obese increased with the frequency of fast food consumption (P = 0.046). Fast food consumption was associated with higher energy intakes, poor diet quality and higher BMI. The likelihood of not meeting the DRI for energy, and of being obese, increased with the frequency of fast food consumption.

Abstract
OBJECTIVE Dietary intake is strongly influenced by the energy density of the diet. The purpose of this study was to determine the association of energy density with diet quality, dietary reference intake (DRI) for energy and lifestyle characteristics in free-living people. SUBJECTS The subjects were Spanish men (n=1491) and women (n=1563) selected in between 1999 and 2000 among the general population according to the 1996 census. RESULTS A low-energy density diet was significantly associated (P<0.001) with a higher consumption of vegetables, fruits, legumes, fish and white meat as compared to high-energy density diets. More subjects (P<0.001) with a high adherence to low-energy density diets meet DRI for energy intake and tended to be closer (P<0.05) to the recommendations of dietary intakes, established by the Spanish Society of Community Nutrition than those following a high-energy density diet. Alcohol consumption, the prevalence of a sedentary lifestyle and smoking significantly increased (P<0.01) across quartile distribution of energy density. CONCLUSION Low-energy density diets of the present population were associated with a healthier lifestyle. Furthermore, our data suggest that adherence to low-energy density diets, with similar characteristics to those found in the present population, promote adequate energy intakes and increase overall diet quality.

Abstract
Homocysteine (Hcy) is recognised as a risk factor for IHD. Serum Hcy is negatively correlated with serum folate levels, the main sources of which are fruits, vegetables and legumes. The present case–control study was designed to examine the relationship between serum Hcy levels and IHD and to assess the role of dietary factors in the southern Mediterranean population of Crete, Greece. Serum Hcy, folate, vitamin B12, creatinine and glucose levels and a full lipid profile were measured in 152 patients with established IHD, median age 64 (range 33–77) years, and 152 healthy control subjects, age- and sex-matched. Dietary data were assessed using a 3 d food intake record. Compared with controls, patients with IHD had significantly higher daily intakes of vitamin B12and MUFA and significantly lower intakes of carbohydrate, fibre, folate, cholesterol,n-3 fatty acids and totaltransunsaturated fatty acids. Moreover, patients had significantly higher serum Hcy, vitamin B12and creatinine levels, but significantly lower folate. Serum folate concentrations in both groups had a significant positive correlation with dietary fibre consumption and a significant inverse correlation with vitamin B12intake. IHD patients should be encouraged to increase their daily dietary intake of fibre, folate andn-3 fatty acids, which are significant components of the traditional Cretan Mediterranean diet. Where dietary folate intake is inadequate, folate supplements are recommended to reduce elevated Hcy levels.

Abstract
OBJECTIVES This study assessed the reproducibility and relative validity of an eight-item self-administered food frequency questionnaire (FFQ) on intake of sugared snacks in Ugandan schoolchildren. A 5-day precoded food behaviour checklist (FBC) was used as validation criteria. Sociodemographic correlates of a sum frequency sugar score were explored. METHODS The study was conducted in Kampala, Uganda, in 2004. Six hundred and fourteen schoolchildren (mean age 12.4 years) completed the FFQ on cakes/biscuits, chocolate, ice sticks, soft drinks, coffee, tea, sugared desserts and sweets/candies at school. They were examined clinically for dental caries. Forty students completed the FFQ twice, 1 week apart and 325 students completed the 5 day FBC at school. RESULTS The mean decayed, missing and filled tooth index score was 0.98 (SD 1.6, range 0-15). Reproducibility scores (Cohen's kappa) for the sugar items ranged from 0.17 (ice sticks) to 0.55 (biscuits). No differences were seen between the average intakes at test and retest. Higher intake was reported in FFQ than in FBC across all sugar items. Crude agreement between students reporting intake at least 3-5 times a week/less than three times a week ranged from 50% to 55% (e.g. biscuits, chocolate) to 87% (tea). Spearman's correlation coefficients ranged from 0.14 (desserts) to 0.27 (sweets). anova revealed significant increase (P = 0.001) in the mean FBC sum scores by increasing quartiles of the FFQ sum scores. The average sum FFQ sugar scores were higher in girls than in boys and higher in older than in younger students. CONCLUSION Fair reproducibility was established for the FFQ sugar items. The FFQ was acceptable in classifying individuals into broad categories of low and high sugar consumption.

Abstract
BACKGROUND Dietary habits are an important determinant of serum homocysteine (tHcy), which may be a marker rather than a cause of progression of the atherosclerotic process. The aim of the present study was to evaluate the nutritional status, and to determine the serum tHcy concentrations in healthy subjects who live in rural areas of Crete, and who theoretically follow a contemporary Mediterranean-style diet. METHODS Serum tHcy, folate, vitamin B(12), creatinine, glucose, and the lipid profile, were measured in 203 (141 men and 62 women) healthy subjects, aged 33-78 years. The major risk factors for cardiovascular disease such as age, gender, cigarette smoking, obesity were recorded and dietary data were assessed using a 3-day weighed food intake record. RESULTS Our population had high serum tHcy, low serum folate concentrations and lower than the traditional Cretan dietary folate intake [median (range): 12.0 (3.6-44.7) micromol L(-1), 7.9 (1.9-15.5) ng mL(-1) and 241 (68-1106) microg, respectively]. Dietary intake of fibre, omega-3, and mono- or/ polyunsaturated fatty acids was also low. An inverse relation was observed between serum tHcy concentrations and serum folate (r = -0.28; P < 0.01) and vitamin B(12) levels (r = -0.33; P < 0.001). CONCLUSIONS Nowadays, the Cretan diet has changed towards a more westernized eating pattern. Given the analytic difficulties in determining the amount of folate in food and the inverse correlation between serum tHcy and folate levels, serum tHcy concentrations may be a useful marker for nutritional status, especially folate deficiency, in healthy subjects.

Abstract
AbstractBackground: Nutritional biomarkers may be better measures of dietary exposure than self-reported dietary data. We evaluated resveratrol metabolites, potential biomarkers of wine consumption, in humans after moderate consumption of sparkling, white, or red wines.Methods: We performed 2 randomized, crossover trials and a cohort study. In the first study, 10 healthy men consumed 30 g of ethanol/day as sparkling wine or gin for 28 days. In the second trial, 10 healthy women consumed 20 g of ethanol/day as white or red wine for 28 days. We also evaluated 52 participants in a study on the effects of a Mediterranean diet on primary prevention of cardiovascular disease (the PREDIMED Study). We used liquid chromatography–tandem mass spectrometry to analyze urinary total resveratrol metabolites (TRMs) and predictive values and ROC curve analyses to assess the diagnostic accuracy.Results: We observed significant increases in TRMs [72.4 (95% confidence interval, 48.5–96.2; P = 0.005), 211.5 (166.6–256.3; P = 0.005), and 560.5 nmol/g creatinine (244.9–876.1; P = 0.005)] after consumption of sparkling, white, or red wine, respectively, but no changes after the washout or gin periods. In the cohort study, the reported daily dose of wine consumption correlated directly with TRMs (r = 0.654; P <0.001). Using a cutoff of 90 nmol/g, we were able to use TRMs to differentiate wine consumers from abstainers with a sensitivity of 72% (60%–84%); and a specificity of 94% (87%–100%).Conclusions: Resveratrol metabolites in urine may be useful biomarkers of wine intake in epidemiologic and intervention studies.

Abstract
Findings on the association of alcohol consumption and oxidation of low-density lipoprotein (LDL), which is thought to play a crucial role in the generation of atherosclerotic lesion, are inconsistent. The aim of the present study was to investigate the association of total alcohol consumption and type of alcoholic beverage with circulating plasma LDL oxidation. This cross-sectional study included data of circulating oxidized LDL (ox-LDL) from a subpopulation of 587 men and women enrolled in a population-based survey conducted in 2000 in Girona (Spain). Multivariate analysis was performed to describe the independent association of alcohol consumption and ox-LDL. Increasing alcohol consumption was associated with high in vivo ox-LDL levels in the present population. The consumption of 10 g of alcohol was associated with an increase of 2.40 U/L of ox-LDL (p = 0.002). Adjustment for dietary variables, leisure-time physical activity, educational level, smoking, LDL-cholesterol, high-density lipoprotein-cholesterol, glycemia, triglycerides, diabetes, body mass index, waist circumference, and systolic and diastolic blood pressures only slightly modified this association (p = 0.003). In this full adjusted model the consumption of 10 g of alcohol per day was associated with an increase of 2.11 U/L of ox-LDL. Consumption of wine (ml/day) was associated with increasing ox-LDL levels (p = 0.029), however, attenuated after controlling for alcohol. No significant relationship of ox-LDL with alcohol-independent consumption of wine, beer, and spirits was observed. Alcohol consumption was independently and directly associated with circulating ox-LDL in the present population.

Abstract
INTRODUCTION Food choice is strongly influenced through economic constraints. The monetary costs for foods, especially those foods associated with a lower risk of obesity, have considerably increased during the last years. The purpose of this study was to determine the cost differences between low and high adherence to two dietary patterns which have been inversely associated with body mass index (BMI) and obesity. METHODS The subjects were Spanish men (n=1547) and women (n=1615) aged 25-74 years who were examined in 1999-2000, in a population-based cross-sectional survey in the northeast of Spain (Girona). Dietary intake was assessed using a food frequency questionnaire. Two dietary quality indices, namely the Mediterranean Diet Score (MDS) and the Healthy Eating Index (HEI), were created. Average food prices were calculated. Anthropometric variables were measured. RESULTS Adjusted linear regression analysis revealed that an increase in 1 Euro (1.25$) of monetary diet costs per day was associated with a change of 0.46 units (P<0.001) and 2.03 units (P<0.001) in the MDS and HEI, respectively. The magnitude of the association was similar for both scores after standardization. Subjects who closely adhered to the MDS and HEI paid daily 1.2 Euro (1.50$) (P<0.001) and 1.4 Euro (1.75$) (P<0.001) more for food consumption, respectively, than those who weakly adhered to these dietary patterns. Multiple linear regression analysis adjusted for several confounders showed an inverse association of the MDS (P=0.011) and the HEI (P<0.001) with BMI. The risk of obesity (BMI> or =30) significantly decreased across quartile distribution of MDS (P=0.004) and HEI (P=0.001). CONCLUSION Data showed that a high adherence to the MDS and HEI, both inversely associated with BMI and obesity, led to higher monetary costs as compared to a low adherence. This might be of importance for public health policies in an effort to develop strategies to promote healthy diets preventing weight gain.

Abstract
BACKGROUND Obesity is associated with oxidative stress, and the oxidation of LDL is thought to play a crucial role in the generation of atherosclerotic lesions. OBJECTIVE The objective was to describe the association of waist circumference (WC) and body mass index (BMI; in kg/m2) with plasma circulating oxidized LDL (ox-LDL) and C-reactive protein (CRP). DESIGN This cross-sectional study included data for circulating ox-LDL and CRP from a subpopulation of 586 men and women enrolled in a population-based survey conducted in 2000 in Girona, Spain. Multivariate analysis was performed to describe the independent association of WC and BMI with ox-LDL and CRP. RESULTS Multivariate logistic regression analysis adjusted for lifestyle, educational level, and dietary confounders showed a direct association of WC (quartile distribution) and BMI categories with ox-LDL (P for linear trend = 0.002) and CRP (P for linear trend = 0.004). Subjects in the top quartile of WC and with a BMI > 29.9 were at high risk of elevated circulating concentrations of ox-LDL and CRP. Further adjustment for cardiovascular disease risk factors did not substantially modify these associations. The risk of high ox-LDL concentrations in overweight (BMI = 25.0-29.9) or obese (BMI > or = 30) subjects with a WC < 102 cm (men) or < 88 cm (women) was not significantly different from that in normal-weight subjects with these WCs. In contrast, overweight or obese subjects with higher WCs (WC > or = 102 cm for men and > or = 88 cm for women) were at significantly higher risk of increased ox-LDL. CONCLUSION High WC was associated with high concentrations of ox-LDL independently of BMI in the study population.

Abstract
BACKGROUND Malnutrition is frequent in cirrhotic patients, and its assessment is difficult. Functional assessment through a dynamometer is a simple method and could minimize these drawbacks. Harris-Benedict prediction formulae estimates the resting energy expenditure but has not been validated for this population. One alternative is the use of indirect calorimetry. AIM To assess nutritional status in cirrhotic patients and estimates the resting energy expenditure through indirect calorimetry and compares it to Harris-Benedict. PATIENTS AND METHODS Thirty four adult hepatitis C cirrhotic outpatients were studied, classified by Child-Pugh and model of end-stage liver disease score. The resting energy expenditure was predicted through Harris-Benedict and measured by indirect calorimetry. Nutritional assessment was done through anthropometry, subjective global assessment, hand-grip strength and a 3-day recall. RESULTS Fifteen (44.2%) were Child-Pug A, 12 (35.3%) B and 7 (20.6%) C, and 33 (97.1%) had model of end-stage liver disease scores less than 20. The resting energy expenditure predicted was higher than the measured (Harris-Benedict 1404.5 +/- 150.3 kcal; indirect calorimetry 1059.9 +/- 309.6 kcal). The prevalence of malnutrition varied between methods (body mass index, muscle arm circumference, subjective global assessment, triceps skinfold thickness and hand-grip strength: 0; 5.9; 17.6; 35.3 and 79.4%, accordingly). Calories and proteins intake were 80% and 85% of recommended amounts and there was inadequate intake of calcium, magnesium, iron and zinc. CONCLUSION Malnutrition was frequent and hand-grip strength seemed to be the most sensitive method for its diagnosis. Calories and protein intakes were inadequate. Considering that the predicted resting energy expenditure was higher than the measured one and the need to offer higher caloric intake, the use of the predicting equation may replace indirect calorimetry.

Abstract
The Mediterranean diet, in which olive oil is the main source of fat, has been associated with a reduced incidence of coronary heart disease (CHD) and low blood pressure levels. Virgin olive oil (VOO), besides containing monounsaturated fat, is rich in phenolic compounds (PC) with antioxidant properties. The aim of this study was to examine the antioxidant and anti-hypertensive effect of two similar olive oils, but with differences in their PC (refined: 14.7 mg/kg versus virgin: 161.0 mg/kg), in 40 males with stable CHD. The study was a placebo controlled, crossover, randomized trial. A raw daily dose of 50 mL of VOO and refined olive oil (ROO) were sequentially administered over two periods of 3 weeks, preceded by 2-week washout periods in which ROO was used. Lower plasma oxidized LDL (p < 0.001) and lipid peroxide levels (p = 0.003), together with higher activities of glutathione peroxidase (p = 0.033), were observed after VOO intervention. Systolic blood pressure decreased after intake of VOO (p = 0.001) in hypertensive patients. No changes were observed in diastolic blood pressure, glucose, lipids, and antibodies against oxidized LDL. Consumption of VOO, rich in PC, could provide beneficial effects in CHD patients as an additional and complementary intervention to the pharmacological treatment.

Abstract
The Mediterranean diet is a healthy eating pattern with protective effects on chronic diseases. The purpose of this study was to assess the relation between BMI and obesity and the level of adherence to the traditional Mediterranean diet. The subjects were Spanish men (n = 1547) and women (n = 1615) aged 25-74 y who were examined in 1999-2000, in a population-based, cross-sectional survey in the northeast of Spain (Girona). Dietary intake was assessed using a FFQ. A Mediterranean diet score, including foods considered to be characteristic components of the traditional Mediterranean diet (vegetables, fruits, pulses, nuts, fish, meat, cereals, olive oil, and wine) was created. An increase of 5 U in the dietary score was associated with a change in the BMI of 0.43 (P = 0.030) and 0.68 (P = 0.007), after controlling for potential confounders, in men and women, respectively. The obesity risk decreased in men (P = 0.010) and women (P = 0.013) with increasing adherence to the traditional Mediterranean dietary pattern. The population in the top tertile of this score were less likely to be obese in both genders [odds ratio (OR) and (95% CI): 0.61 (0.40-0.92) in men; 0.61 (0.40-0.93) in women] after adjusting for potential confounders. These data suggest that the traditional Mediterranean dietary pattern is inversely associated with BMI and obesity. This finding may be useful in the development of dietary approaches for dietary counseling and the prevention of obesity.

Abstract
BACKGROUND No intervention studies have explored the anti-inflammatory effects of different alcoholic beverages on markers of atherosclerosis. We embarked on a randomized, crossover, single-blinded trial to evaluate the effects of wine and gin on inflammatory biomarkers of atherosclerosis. METHODS AND RESULTS Forty healthy men (mean age, 37.6 years) consumed 30 g ethanol per day as either wine or gin for 28 days. Before and after each intervention, we measured the expression of lymphocyte function-associated antigen 1 (LFA-1), Mac-1, very late activation antigen 4 (VLA-4), and monocyte chemoattractant protein (MCP-1) in monocytes, as well as the soluble vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), interleukin-1alpha (IL-1alpha), C-reactive protein (hs-CRP) and fibrinogen. After either gin or wine consumption, plasma fibrinogen decreased by 5 and 9%, respectively, and cytokine IL-1alpha by 23 and 21%. The expression of LFA-1 (-27%), Mac-1 (-27%), VLA-4 (-32%) and MCP-1 (-46%) decreased significantly after wine, but not after gin. Wine reduced the serum concentrations of hs-CRP (-21%), VCAM-1 (-17%) and ICAM-1 (-9%). CONCLUSIONS Both wine and gin showed anti-inflammatory effects by reducing plasma fibrinogen and IL-1alpha levels. However, wine had the additional effect of decreasing hs-CRP, as well as monocyte and endothelial adhesion molecules.

Abstract
BACKGROUND Moderate alcohol consumption protects against ischemic heart disease, possibly through an antiinflammatory effect. However, little is known about the mechanisms by which alcohol may interfere in the development of atherosclerosis. OBJECTIVE We analyzed the effects of 2 alcoholic beverages with high (red wine) or low (gin) polyphenolic content on human monocyte adhesion to an endothelial cell line (Ea.hy926). DESIGN This was a randomized, crossover trial with 8 healthy men. After a washout period, the subjects received 30 g ethanol/d as red wine or gin for 28 d. Before and after each intervention, a dietary survey and laboratory analysis were performed. Adhesion of human monocytes to endothelial cells was measured in basal and stimulated [by tumor necrosis factor alpha (TNF-alpha)] conditions. Adhesion molecules involved in monocyte-endothelium interactions were determined on the cell surface. RESULTS The mean expression of very late activation antigen 4 on monocytes significantly decreased after red wine intake [by 18% (95% CI: 33%, 3%); P = 0.022]. Monocyte adhesion significantly increased after TNF-alpha stimulation of endothelial cells. This increase, however, was 39% less (95% CI: 48%, 35%; P = 0.049) after gin intake than after the respective washout period and was nearly abolished by red wine intake [96% less than after the respective washout period (95% CI: 142%, 76%); P < 0.001]. The reduction after red wine intake was significantly different from that after gin intake (P = 0.014). CONCLUSIONS TNF-alpha-induced adhesion of monocytes to endothelial cells was virtually abolished after red wine consumption but was only partially reduced after gin consumption. This effect may be due to the down-regulation of adhesion molecules on the monocyte surface.

Abstract
OBJECTIVE The aim of the present study was to analyse the relation between age and both dietary habits and leisure-time physical activity, and to determine nutrient inadequacy of aged groups in our population. DESIGN Cross-sectional study. SETTING A random sample of the 25-74-y-old population of Gerona, Spain. SUBJECTS A total of 838 men and 910 women were selected from among the general population according to the 1991 census. OUTCOME MEASURES Analysis of dietary habits, including amount and type of alcohol consumption, and detailed evaluation of leisure-time physical activity. RESULTS Nutrient densities of carbohydrates, vitamin B(1), vitamin B(12), vitamin C, vitamin E, folate, potassium, iron, magnesium, copper, and dietary fiber increased significantly (P<0.05) with age in both genders, whereas an inverse trend was observed for total fat, saturated fatty acids, cholesterol, and sodium. Multiple linear regression analysis revealed a direct association of healthy dietary habits, characterized through a composite dietary score, with age after adjusting for several confounders both in men and women (P<0.001). This score was composed of folate, vitamin C, vitamin E, beta-carotene, dietary fibre, cholesterol, saturated fatty acids, and sodium. In all, 29 and 10% of male and female subjects aged 65-74 y, respectively, reported inadequate intakes of six or more of 16 nutrients. Total leisure-time physical activity increased with age in men (P<0.002), and was not different among female age groups. CONCLUSION Dietary behaviours and levels of physical activity spent during leisure time indicate a healthy lifestyle of the aged men and women in the present population. Nutrient inadequacy observed in some aged men and women, however, deserves particular intervention of health-care programmes for this growing part of our society.

Abstract
Glutathione peroxidase (GPx) is one of the most important antioxidant enzymes in humans. We studied the relationship between erythrocyte GPx activity and fasting serum insulin, plasma glucose, and C-peptide, estimates of insulin resistance from the homeostasis model of assessment as well as dietary fat intake in 408 normotensive nondiabetic pregnant women from Camden, NJ. GPx activity and the metabolic parameters were determined at entry to care (16 wk of pregnancy) and during the third trimester. GPx activity and the levels of insulin resistance increased significantly between entry and the third trimester. Statistically significant associations, all positive, were observed between GPx activity and fasting insulin (beta = 0.009, P < 0.001), glucose (beta = 0.975, P < 0.05), C-peptide (beta = 1.537, P < 0.01), and insulin resistance from the homeostasis model of assessment (beta = 0.209, P < 0.01). Dietary intakes of fat and polyunsaturated fatty acids were positively correlated with GPx activity as well. African Americans had significantly higher GPx activity, dietary fat, and polyunsaturated fatty acid intake than Hispanics and Caucasians. In conclusion, we demonstrated that normal pregnancy is associated with increased GPx activity and insulin resistance. There are ethnic differences in antioxidant response and dietary fat intake. Our findings suggest a potential link among antioxidant defenses, insulin resistance, and dietary fat intake.

Abstract
BACKGROUND AND AIM Several genetic polymorphisms have been found to be involved in cardiovascular risk, and many studies have documented the beneficial effect of systematic physical activity (PA) on the cardiovascular system. Our aim was to investigate the interactive effects of PA and genetic background on plasma lipids and homocysteine (tHcy) levels. METHODS AND RESULTS Clinical and metabolic parameters, dietary intakes and some polymorphisms of the genes involved in cardiovascular risk (Apo E, fatty acid binding protein-2, Apo AII, hepatic lipase and methylene tetrahydrofolate reductase) were determined in 100 men aged over 40 years who cycle 120-150 Km/week and 100 age-matched sedentary controls. The physically active subjects had lower concentrations of plasma LDL cholesterol (LDL-C), triglyceride (TG), Apo B, glucose and tHcy, and higher concentrations of plasma HDL cholesterol (HDL-C) and Apo AI than the sedentary men; they also had larger LDL particle sizes (LDLs). The LDL-C and Apo B raising effect of the Apo E epsilon 4 allele detectable in the sedentary subjects was totally absent in the cyclists, in whom the LDL-C and Apo B lowering effect of the epsilon 2 allele was observed. PA blunted the TG-raising effect of the Apo AII-265TT genotype, and amplified the HDL-C raising effect of the HL-250AA genotype. PA had a small but significant lowering effect on plasma tHcy adjusted for folate levels in subjects with the 677TT genotype of the MTHFR gene. CONCLUSIONS Extended high-intensity PA in men aged over 40 years may modify their metabolic cardiovascular risk factors even in the presence of some unfavourable genotypes.

Abstract
The aim of the present study was to determine the relationship of BMI with other cardiovascular risk factors, leisure-time physical activity and diet. Participants were recruited in a cross-sectional population-based survey in a southern-Europe Mediterranean population (Spain); cardiovascular risk factors were measured, and leisure-time physical activity and diet intake were evaluated. Linear regression analysis adjusted for several confounders showed a significant, direct association of BMI and total cholesterol (P<0.005) and LDL-cholesterol (P<0.006), in men. HDL-cholesterol was inversely related to BMI in both sexes (P<0.0001). Higher BMI was more frequent in less-active men (P<0.04) but not in women. BMI increased significantly (P<0.0001) by 1.92 kg/m(2) with each 4.18 MJ consumed in men but not in women. Dietary intakes of carbohydrate (P<0.03), total fat (P<0.03) and saturated fatty acids (P<0.02) were directly associated with BMI in men but not in women, in whom protein intake was correlated (P<0.001) with BMI. Linear regression models including dietary components explained up to 10.6 and 21.1 % of BMI variability in men and women, respectively. Sex differences in the association of BMI with total cholesterol, and LDL-cholesterol, may account for the lower risk for CHD in women compared with men of similar BMI reported in the literature for the southern-Europe Mediterranean region. An increases of BMI may be more deleterious in populations in which it is accompanied by other risk factors such as a higher intake of total fat and, particularly, of saturated fatty acids, or lower leisure-time physical activity.

Abstract
The aim of the present study was to analyse the relationships among different intensities of leisure-time physical activity (PA) and cancer-protective dietary components, cancer-related biological (general and central obesity) and lifestyle factors (heavy smoking and excessive alcohol consumption). The present population-based cross-sectional study (765 men and 812 women from the general population of Gerona, Spain) included measurement of anthropometrical data, dietary intake, and alcohol and cigarette consumption and furthermore detailed evaluation of total leisure-time physical activity, including measurement of different intensities. Logistic regression analysis adjusted for several confounders was used to analyse the relationships among variables. A composite variable composed of dietary fibre, vitamin C, alpha-tocopherol, beta-carotene and folate was directly associated with higher levels of leisure-time PA in both genders, after further adjusting for energy intake [odds ratio (OR) of low versus second tertile of total leisure-time PA was 1.98 (95% confidence interval (CI) 1.22-3.23) for men and OR of low versus top tertile of total leisure-time PA was 1.75 (95% CI 1.07-2.84) for women]. Low to moderate- but not high-intensity leisure-time PA was directly related to higher intakes of these nutrients. Heavy smoking was inversely associated with higher levels of total leisure-time PA in men. With the exception of central obesity in women, there was no significant relationship between the cancer-related biological and lifestyle factors, and low to moderate-intensity leisure-time PA in both genders. In contrast, central obesity (OR 0.31, 95% CI 0.16-0.63) and heavy smoking (OR 0.38, 95% CI 0.16-0.96) were significantly related to high-intensity but not to total or low to moderate-intensity leisure-time PA in men and women, respectively. The observed relationships between leisure-time PA and several of the studied cancer-associated variables might partially account for the protective effect of physical activity against cancer observed in the literature. However, different intensities of leisure-time PA were distinctly associated with the mentioned cancer-related dietary, biological and lifestyle factors. Most importantly, although some of these variables were not associated with total leisure-time PA a significant relationship was observed for intensities of leisure-time PA. This should be considered when analysing the relationship between leisure-time PA and cancer.

Abstract
METHODS: We determined the effect of smoking on PON1 activity levels in a population-based sample of 1380 subjects and examined the possibility of regular physical activity modulating the effect of cigarette smoking on PON1 activity levels at a population level. RESULTS: Mean PON1 activity was significantly lower in smokers than in non- or ex-smokers (237.6+/-8.4 vs. 276.7+/-5.3 U/l, mean+/-S.E.M.; P= 0.001). PON1 activity levels were significantly higher in physically active subjects than in those who were inactive (296.1+/-10.4 vs. 260.1+/-9.2 U/l; P=0.002). Inactive smokers showed significantly lower PON1 activity levels than inactive nonsmokers (P=0.002). These differences disappeared when active nonsmokers were compared with active smokers. Serum PON1 activity levels were found to be significantly increased in active smokers compared to those in inactive smokers. A statistically significant interaction (P=0.003) between smoking and physical activity on PON1 activity was observed. CONCLUSION: Smoking appears to have a deleterious effect on PON1 activity levels. Being physically active clearly attenuates this effect.

Abstract
OBJECTIVE To assess the validity of the food-frequency questionnaire used in the European Prospective Investigation of Cancer (EPIC FFQ) for estimating nutrient intake in an adolescent population. DESIGN Sixty-seven schoolchildren (mean age: 12.3 +/- 0.3 years) were recruited to complete a 7-day weighed dietary record (7-day WDR), the EPIC FFQ and supply one 24-hour urine collection. SETTING Harris Academy in Dundee (UK). RESULTS Fifty subjects completed both dietary assessment methods. Thirteen of these were classified as underreporters with energy intake/basal metabolic rate < 1.14. The EPIC FFQ showed higher estimates than the 7-day WDR for all nutrients. The median Spearman correlation coefficient for the nutrients examined was found to be 0.31 and increased to 0.48 after adjustment for total energy. The limits of agreement were as far apart as 13.4 MJ, 120 g, 270 g, 120 g and 1170 mg for energy, fat, sugar, protein and calcium, respectively. Correlations between urine and 7-day WDR dietary nitrogen and potassium were found to be statistically significant with r = 0.45 (P < 0.05) and r = 0.78 (P < 0.001) respectively. The median proportion of subjects that appeared in the same and opposite third of intake was found to be 45.9% and 10.8%, respectively. CONCLUSIONS The EPIC FFQ seems adequate to correctly classify low, medium and high consumers and might therefore be used to identify adolescent population groups at risk or for differences between populations. However, agreement between the EPIC FFQ and the 7-day WDR was very poor on both a group and an individual basis, and demonstrates that the EPIC FFQ is not an appropriate method for estimating absolute intakes in this age group.

Abstract
Tobacco and alcohol consumption are strongly related to other cardiovascular and cancer risk factors. The aim of the present study was to analyse the association of nutrient intake, blood lipid variables and leisure-time physical activity with tobacco and alcohol consumption status. Participants were recruited in a cross-sectional population-based survey, including cardiovascular risk factor measurements and evaluation of physical activity and diet intake in a Mediterranean population (n 1748). Multiple linear regression analysis, adjusted for several confounders, showed a direct association of saturated fatty acids (g and % total energy intake), dietary cholesterol intakes and serum triacylglycerol with smoking. An inverse association was observed for smoking and unsaturated fatty acids (% energy intake), vitamin C, alpha-tocopherol and beta-carotene intakes, leisure-time physical activity and HDL-cholesterol. These associations were not observed for alcohol drinking. After adjusting for the confounders earlier mentioned, low dietary intakes of vitamin C and dietary fibre were more likely in heavy-smokers as compared with non-smokers (odds ratio 1.74 (95 % CI 1.07, 2.73) and 1.94 (95 % CI 1.29, 2.92) of low vitamin C (<60 mg/d) and dietary fibre intakes (<10 g/d) respectively). Alcohol consumption was directly associated with HDL-cholesterol and triacylglycerol, and attenuated the effects of smoking on HDL-cholesterol. These results suggest that the dietary intake of fibre and several antioxidant components of the Mediterranean diet is reduced in smokers, who also show an adverse lipid profile. However, the worst triacylglycerol levels are associated with the combination of heavy smoking and heavy alcohol drinking. Moderate alcohol consumption was not associated with an unhealthy diet pattern or adverse lipid profile. The health benefits of the Mediterranean diet appear to be strongly counteracted by smoking.

Abstract
Olive oil, rich in oleic acid, could play a particular beneficial role in the anti-atherogenic effects attributed to the Mediterranean diet. Paraoxonase (PON1) has emerged as the component of high-density lipoproteins (HDL) most likely to explain its ability to attenuate the oxidation of low-density lipoproteins. We hypothesised that oleic acid intake might be associated with changes in PON1-HDL associated particles, and investigated the impact, if any, on this association of the PON1-192 polymorphism, a common polymorphism that strongly modulates PON1 activity. Six hundred and fifty-four men randomly selected from the census were studied. Oleic acid intake was calculated from a 72-h recall questionnaire with specific software. Oleic acid intake groups (low vs. high) were created by stratifying the population according the median value as a cut-point. After adjusting for confounding variables, high oleic acid intake was associated with increased HDL cholesterol levels and PON1 activity only in subjects with the QR and the RR genotypes, respectively. Analyses of the variance showed a statistically significant interaction between PON1-192 genotypes and oleic acid intake for log PON1 activity (P=0.005) and a marginally significant interaction for HDL cholesterol (P=0.066). These results suggest that the beneficial effect of increasing oleic acid intake on HDL and PON1 activity at population level is especially observed in subjects carrying the R allele of the PON1-192 polymorphism.
