Declared experiences of risky sexual behaviors in relation to alcohol consumption in the first year of college

Fundamentos: En universitarios, el consumo de alcohol de mayor riesgo (borracheras y binge drinking (BD), tiene consecuencias negativas sobre su desarrollo y probablemente facilita conductas sexuales de riesgo. El objetivo de este trabajo fue estudiar si las conductas sexuales de riesgo al consumir alcohol (CSRA) se asocian a los consumos de mayor riesgo. Métodos: Estudio multicéntrico transversal con datos del Proyecto uniHcos, de universitarios de 1er año de 11 universidades españolas, entre los cursos 2011-2012 y 2017- 2018. Datos recogidos mediante cuestionario autoadministrado. Se realizó un análisis uni y bivariable, evaluando la significación estadística de las diferencias de prevalencia con chi-cuadrado. Se utilizó media y desviación típica para variables cuantitativas y como estadístico de contraste t de Student. Resultados: 9.862 participantes (72,2% mujeres). El 90,3% consumió alcohol y el 60,9% tuvo borracheras en último año; el 49% tuvo BD en el último mes. El consumo en el último mes y las borracheras fueron mayores en hombres y < 21 años. Las CSRA fueron superiores entre los que se emborracharon (15,7% sexo sin protección, 1,9% abuso sexual y 0,7% aprovecharse sexualmente) y consumieron en BD (17,1%, 1,9% y 0,7%). Las mujeres con ambos consumos de riesgo presentaron más abusos sexuales (2,2%), y los hombres fueron quienes más se aprovecharon sexualmente de otros (borracheras:1,2%; BD: 1,3%). Conclusiones: El consumo de alcohol está por encima de grupos similares. El BD tiene un patrón similar por género y edad. Las CSRA se asocian a los consumos de mayor riesgo, no detectándose en este grupo diferencias por género en sexo sin protección, sí en otras CSRA.Objective: In college students, higher risk alcohol consumption (drunkenness and binge drinking-BD) has negative consequences on their development and and probably facilitates risk sexual behaviors. The objective was to study if risky sexual behaviors when consuming alcohol (RSBA) are associated with higher risk consumption. Methods: Cross-sectional multicenter study with UniHcos Project, 1st year university students from 11 universities in Spain, academic years 2011-2012 to 2017-2018 data. This data were collected by self-administered questionnaire. A uni and bivariate analysis was performed, evaluated the statistical significance of the differences in prevalence with chi-square. Mean and standard deviation were used for quantitative variables and Student's t test statistic was used. Results: 9,862 subjects (72.2% women). 90.3% reported having consumed alcohol and 60.9% had drunk the last year, 49% BD in last month. It was deteded in men, significantly higher consumption in the last month and drunkenness. Last month consumption and drunkenness were significantly higher in men and in <21 years. The RSBA were significantly higher among who were drunk (15.7% unprotected sex, 1.9% sexual abuse and 0.7% taking sexual advantage) and had BD (17.1%, 1.9% and 0.7 %). Women with both risk consumptions had more sexual abuse (2.2%), and men had greater behaviors of taking sexual advantage of someone (drunk: 1.2%; BD: 1.3%). Conclusions: Alcohol consumption was above similar groups. BD consumption was similar by gender and age. Risk sexual behaviors appear mainly in problematic consumption. Gender differences are not detected in alcohol consumers in unprotected sex but deteded in the rest.Financiación: El estudio ha sido financiado por el Plan Nacional Sobre Drogas del Ministerio de Salud, Servicios Sociales e Igualdad.

Alcohol use and family-related factors among Spanish university students: the unHicos project

Background: During adolescence and youth there are relevant changes in the consolidation, gain or loss of consumption habits and lifestyles and the family factors has a fundamental role to development these habits. The study of the consumption of toxins, such as alcohol intake, is crucial at this stage due to the repercussions that said consumption presents in adulthood. Therefore, the objective of our study was to evaluate the associations between alcohol consumption patterns and related family factors (family functioning, family history of alcohol consumption) in Spanish university students. Methods: Observational, descriptive, cross-sectional, multicenter study, carried out in first-year university students from 11 Spanish universities. Through an online questionnaire, alcohol consumption (risky consumption and intensive consumption or binge drinking), family functioning and history of alcohol in the family were evaluated. Risky alcohol consumption and binge drinking were assessed using the AUDIT test, and family functioning was assessed using the family APGAR questionnaire. A descriptive analysis of the data was performed, as well as the Chi-Square test and Student's T-Test, and non-conditional logistic regression models were carried out to examine this association. Results: The prevalence of risky alcohol consumption identified in the 10,167 respondents was 16.9% (95% CI = 16.2–17.6), and that of BD was 48.8% (95% CI = 47.9–48.8). There is a significant association between risky alcohol consumption and family functioning in students of both sexes, with greater consumption in the face of severe dysfunctional support (men OR = 1.72; p < 0.001 and women OR = 1.74; p < 0.001) and family history of consumption (p = 0.005). Regarding the binge drinking pattern, no statistically significant differences were observed. Conclusions: Risky alcohol consumption in university students is associated with dysfunctional family support, unlike the binge drinking pattern, where there is no such association. The findings of this study show the importance of creating prevention programs focused on the family approach in university students, which include alcohol screening in the population with a family history of this substance, and greater social support from health services.This work was supported by the National Drug Plan, Ministry of Health, Social Services and Equality of Spain (Codes: 2010|145, 2013|034 and 2020|030) and project PI16/01947

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
