Objective: The first COVID-19 lockdown was a very restrictive situation that may have impacted on the prevalence and patterns of cannabis use. The aim of this systematic review was to assess the evidence on cannabis use and reasons for use in different countries during first lockdown in young adults and general population., Methods: This study followed PRISMA guidelines, and the review protocol was registered in PROSPERO (registration CRD42022303181). The search was carried out in PubMed, Scopus, Web of Science y Embase databases. Inclusion criteria were: cross-sectional or cohort studies; population ≥16 years; exploring cannabis use during lockdown; and English or Spanish language., Results: Thirty studies, conducted in European countries (n=17), North America (n=12) and rest of the world (n=1), were analysed. The overall prevalence of cannabis use was found to be largely unchanged, but regular users tended to maintain (between 39.5% and 96.8% of the sample) or increase cannabis use (between 2.9% and 51.6%). The main decreases were among occasional users. Some reasons for the increase were boredom, loneliness, stress, coping and depressive symptoms. In addition, young people were the heaviest users, and being younger, live without family, financial problems and a low educational level were significantly (p-value<0.05) associated with increased use., Conclusions: Most regular users maintained or slightly increased their use, with young people being the main users. Concerning reasons for use like coping and depressive symptoms were found. Cannabis use needs to be addressed with strategies focused on the young population, considering occasional and regular use, as well as motivations.

Objective: For cancer incidence, tobacco use is one of the main avoidable risk factors.The aim of this study is to describe the frequency, trend and geographical distribution of the incidence of tobacco-associated tumours in the León Health Area, Spain., Material and Methods: An observational, descriptive study was carried out on tumours of Hospital Registry of Tumours of the University Hospital Complex of León between 1997 and 2014. León Health Area residents, associated with smoking were included. Gross and adjusted rates were calculated and adjusted for triennials. For the analysis of spatial distribution, municipal relative hazards were smoothed by adjusting the Besag, York, and Mollié model and for their posterior probabilities for relative hazards to be higher than 1, using Bayesian methods., Results: A total of 7,103 cases were included. Crude incidence rates rose from 116.4 (1997-1999) to 228.0 (2012-2014) per 100,000 men, and from 19.8 (1997-1999) to 44.5 (2012-2014) per 100,000 women. The adjusted rates for the European population also increased from 116.2 (1997-1999) to 136.9 (2012-2014) per 100,000 men, and from 11 (1997-1999) to 24.5 (2012-2014) per 100,000 women. In the south and centre of the province, there were municipalities with high relative hazards, several of them higher than 2 with posterior probabilities of 1., Conclusions: Tumours associated with tobacco increased in the triennial studied, especially in women. The different geographical distribution can be used as a tool to prevent tobacco consumption in the areas involved., (Copyright © 2018 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Introduction: eating disorders (ED) are particularly common in young people., Objective: To determine the prevalence of eating disorders in college students and its associated factors., Methods: Study of prevalence in young Spanish university uniHcos project. Using unconditional logistic regression have determined the magnitude of the association between the risk factors associated with lifestyle and ED measured by questionnaire Sick, Control, One, Fat, Food (SCOFF)., Results: The prevalence of ED was 19.5%, being higher in women (ORa=1.59; p=0.006). In boys, have criteria of developing an eating disorder was associated with living in halls of residence, "binge drinking" and problematic Internet use. In women studying different courses at Health Sciences (ORa=1.50) and problematic Internet use (ORa=2.33). Those women at risk of ED more frequently had depression (ORa=2.02), menstrual pains (ORa=1.81) and perceived poor health (ORa=1.70). In men, those at risk for eating disorders more frequently had poor perceived health (ORa=2.42)., Conclusions: The risk of a positive outcome in the scoff in our study is similar to that reported for other populations of students as well as their association with certain health problems and addictions. By gender differences that need attention in the design of prevention and control strategies were observed., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.)

The University stage gives rise to social and personal changes as the independence of the nuclear family and the increased responsibilities that are related to the acquisition and/or consolidation of life styles and habits that may determine the future health status. Inadequate nutrition, a high level of inactivity, risky sexual behavior, abuse of new technologies or starting consumption of legal and illegal drugs, are among the most significant risk behaviors in this phase. In order to know how to set and / or consolidate the habits and lifestyles in the university stage and health effects in the future, to born the uniHcos project. It is a dynamic cohort of university students who join the project during the first academic year and will be followed during their stay at college and working life. The follow-up will be biennially and for the capture and the information collection will be used on-line technologies. This paper aims to show the uniHcos project to the scientific community as well as present preliminary results found so far in the two cohorts established since 2011.

Background: Stomach cancer is common and has a high mortality rate. The aim of this study was to analyze the incidence and trend of gastric cancer in the health area of León., Methods: We designed an observational descriptive study that included patients enrolled in the Hospital Tumor Registry of the Centro Asistencial Universitario de León with a diagnosis of malignant neoplasm of the stomach (ICD 9-151, ICD10-C16) between 01/01/1994 and 12/31/2008 and resident in the health area of León. The population supplied by Spain's National Institute of Statistics was used as the denominator. The time trend was evaluated with a Poisson regression model. To study the spatial distribution, we estimated municipal relative risks (RR) smoothed by fitting the Besag, York and Mollié model and the posterior probability (PP) of RR>1 using bayesian methods., Results: A total of 1680 cases were included. The average crude incidence rate was 40.0 new cases per 100,000 in men and 23.5 for women. The incidence decreased by 1.4% per year (men: 1.2%, women: 1.8%). The age adjusted rates (European standard population) decreased from 26.9 (1994-6) to 22.2 (2006-8) new cases per 100,000 population in men and from 13.3 to 9.5 in women. Three geographical areas showed a RR excess with a PP higher than 0.9., Conclusions: The observed rates are among the highest in Spain and their declining trend is lower than expected. Some municipalities had an excess risk., (Copyright © 2012 Elsevier España, S.L. and AEEH y AEG. All rights reserved.)

Background: There is an excess incidence of colorectal cancer (CRC) and mortality from this disease in the health area of Leon. The aim of the present study was to determine trends in CRC and its geographical distribution., Methods: Cases included in the Hospital Registry of Tumors of the Centro Asistencial Universitario de León from 1994-2008 and occurring in patients residing in the health area of Leon were studied. Time trends were evaluated with a Poisson regression model. To analyze geographical distribution, the smoothed relative risks (RR) of the municipalities adjusted by the Besag, York and Mollié model were calculated, and their subsequent probability of an RR>1 (PP) was calculated using Bayesian methods., Results: A total of 4,136 cases were included. Rates standardized to the European standard population ranged from 49.6 (1994-6) to 63.5 new cases per 100,000 inhabitants in men (2006-8) and from 29.6 to 33.8 in women. An annual 2% increase was found for all localizations, ranging from 1.8% in the rectum to 3.6% in the proximal colon. In all localizations, the increase was greater in men than in women. Several municipalities in the health area of Leon showed an excess risk. The geographical pattern observed was due especially to the distribution of colon cancer., Conclusions: The incidence rates observed were high and were increasing. Special attention should be paid to CRC in the health area of Leon, mainly in the municipalities with excess risk., (Copyright © 2011 Elsevier España, S.L. and AEEH y AEG. All rights reserved.)
