Objective: An urgent need in dietary assessment is the development of short tools that provide valid assessments of dietary quality for use in time-limited settings. The present study assessed concurrent and construct validity of the short Diet Quality Screener (sDQS) and brief Mediterranean Diet Screener (bMDSC) questionnaires. Design: Relative validity was measured by comparing three dietary quality indicesthe Diet Quality Index (DQI), the modified Mediterranean Diet Score (mMDS) and the Antioxidant Score (ANTOX-S) -derived from the two questionnaires with those from multiple 24 h recalls over 12 months. Construct validity was demonstrated by correlations between average nutrient intake recorded on multiple 24 h recalls and the DQI, mMDS and ANTOX-S derived by the short screeners. Setting: Both short questionnaires were administered to 102 participants recruited from a population-based survey in Spain. Results: DQI, mMDS and ANTOX-S correlated (P , 0?001) with the corresponding 24 h recall indices (r 5 0?61, 0?40 and 0?45, respectively). Limits of agreement lay between 96 and 126 %, 59 and 144 % and 61 and 118 % for the DQI, ANTOX-S and mMDS, respectively. Dietary intakes of fibre, vitamin C, vitamin E, Mg and K reported on the 24 h recalls were positively associated (P , 0?04) with the DQI, mMDS and ANTOX-S indices. Conclusions: The sDQS and bMDSC provide reasonable approximations to food-based dietary indices and accurately situate subjects within the indices constructed for the present validation study. Keywords Validation Short screener Construct validity Diet quality Mediterranean dietNon-communicable diseases such as CVD and cancer are estimated to be responsible for 60 % of world deaths, and dietary habits appear to be strong determinants for their development (1) . Therefore, analysis of dietary habits in large populations to identify dietary deficiencies is of paramount importance. FFQ are widely used to estimate food intake in large epidemiological settings. However, full-length FFQ are time consuming for participants and thus are unsuitable for routine clinical use and for non-dietary studies incorporating a broad spectrum of measurements. For this reason, several brief screening tools have been developed to assess intakes of major food groups. Most of these short dietary questionnaires focus on one or two dietary components (2)(3)(4)(5)(6)(7) . Only a few brief screeners assess a broader range of dietary intake (8,9) , an approach that might help to identify subjects at nutritional risk by indicating their level of adherence to diet quality recommendations. To address the need for a brief, effective instrument, we designed short dietary screeners for two different settings. The brief Mediterranean Diet Screener (bMDSC) is intended to assess adherence to the healthy Mediterranean dietary pattern. The short Diet Quality Screener (sDQS) was created to estimate overall diet quality in primary-care settings. We calculated a modified Mediterranean Diet Score (mMDS) and an y A full roster of REGIC...

Background. Breast cancer (BC) is the first cause of cancer morbidity and mortality in women. This disease has been linked to obesity; however, it is not clear how fat accumulation affects women who survive breast cancer. Although the visceral adiposity index (VAI) is a marker of cardiometabolic risk and adipose tissue dysfunction, it is not clear how it changes in breast cancer survivors. The aim of this investigation was to compare VAI in women with and without breast cancer. Methods. A case-control cross-sectional study was conducted on women who were BC survivors and women without the history of BC (control group). Body composition was assessed using electrical bioimpedance while VAI by means of waist circumference (WC), body mass index (BMI), triacylglycerols (TG), and high-density lipoprotein cholesterol (HDL-C). Results. 49 women in the BC survivor group and 50 in the control group. WC was wider in the survivor group as regards control (93.65 ± 10.48 vs. 88.52 ± 9.61 cm) ( p = 0.025 ); at once, TG and VAI were significantly higher for the survivor group (243.55 ± 199.84 vs. 159.84 ± 75.77) ( p = 0.007 ) and (11.03 ± 11.15 vs. 6.41 ± 3.66) ( p < 0.005 ), respectively. Body composition parameters were similar in both groups. Conclusions. VAI is higher in women who are BC survivors in comparison with controls matched by age and bodyweight.
