The objectives of this study were to establish whether alcohol risk consumption varied during COVID-19 confinement, and how these variations manifested as a function of different sociodemographic variables. METHODS The study was conducted during confinement with 3,779 participants in Spain. We used an online survey with sociodemographic variables (sex, age and employment situation) and AUDIT-C. Frequency and mean difference analysis were performed (Student t, ANOVA and Kruskal-Wallis) to establish intra-group variations before the pandemic compared to during confinement, and intergroup for each time period, reporting effect size. RESULTS Alcohol risky consumption presented high prevalence rates before confinement (25,9% of alcohol consumers), showing a general decrease during confinement (15,1%), both in men (X2=224,82...

A list has been compiled which is available upon request from the authors (blay@castor.daa.uv.es;juan@pleione.daa.uv.es).The boundaries of the instability strips have been defined by observational β – c0 HR diagrams based on Stræmgren photometry (Sterken & Jerzykiewicz 1993 = SK93). The ZAMS has been set as the lower limit of both strips. Low and high temperature limits are set as those given by SK93 and the upper limit is fixed by the photometry β of Cep stars found in the literature. For the SPB stars we have followed the same procedure. We have found the following boundaries: β Cephei: 0.2295c0 + 2.6263 > β > 0.0394c0 + 2.5656; 0.17 > c0 > –0.1; SPB: 2.630 > β > 0.2642co + 2.6207; 0.8 > c0 > 0.17.
