Mental ill-health during COVID-19 confinement.

BACKGROUND: Confinement due to COVID-19 has increased mental ill-health. Few studies unpack the risk and protective factors associated with mental ill-health and addictions that might inform future preparedness. METHODS: Cross-sectional on-line survey with 37,810 Catalan residents aged 16+ years from 21 April to 20 May 2020 reporting prevalence of mental ill-health and substance use and associated coping strategies and behaviours. RESULTS: Weighted prevalence of reported depression, anxiety and lack of mental well-being was, respectively, 23, 26, and 75%, each three-fold higher than before confinement. The use of prescribed hypnosedatives was two-fold and of non-prescribed hypnosedatives ten-fold higher than in 2018. Women, younger adults and students were considerably more likely, and older and retired people considerably less likely to report mental ill-health. High levels of social support, dedicating time to oneself, following a routine, and undertaking relaxing activities were associated with half the likelihood of reported mental ill-health. Worrying about problems living at home, the uncertainty of when normality would return, and job loss were associated with more than one and a half times the likelihood of mental ill-health. With the possible exception of moderately severe and severe depression, length of confinement had no association with reported mental ill-health. CONCLUSIONS: The trebling of psychiatric symptomatology might lead to either to under-identification of cases and treatment gap, or a saturation of mental health services if these are not matched with prevalence increases. Special attention is needed for the younger adult population. In the presence of potential new confinement, improved mental health literacy of evidence-based coping strategies and resilience building are urgently needed to mitigate mental ill-health.

Gender differences in sexual risk behaviour among adolescents in Catalonia, Spain.

OBJECTIVE: To analyze the factors associated with sexual risk behavior in adolescent girls and boys in order to plan future school health interventions. METHODS: A cross-sectional study with two-stage cluster sampling that included 97 schools and 9,340 students aged between 14 and 16 years old was carried out in 2005-2006 in Catalonia (Spain). For the survey, a self-administered paper-based questionnaire was used. The questionnaire contained items on sociodemographic variables, use of addictive substances and mood states, among other items. These variables were tested as risk factors for unsafe sexual behavior. RESULTS: This study included 4,653 boys and 4,687 girls with a mean age of 15 years. A total of 38.7% of students had had sexual relations at least once and 82.3% of boys and 63.0% of girls were engaged in sexual risk behaviors. The prevalence of sexual relations and risk behaviors was generally higher in boys than in girls, independently of the variables analyzed. Boys had more sexual partners (P<.001) and used condoms as a contraceptive method less frequently than girls (P<.001). Foreign origin was related to unsafe sexual activity in both genders. Alcohol consumption was also a risk factor in boys. CONCLUSIONS: Sexual risk behaviors among adolescents in Catalonia are higher in boys than in girls. Factors related to unsafe sexual activity in boys were foreign origin and alcohol consumption. In girls only foreign origin was a significant risk factor.

Safety of intramuscular influenza vaccine in patients receiving oral anticoagulation therapy: a single blinded multi-centre randomized controlled clinical trial.

BACKGROUND: Influenza vaccines are recommended for administration by the intramuscular route. However, many physicians use the subcutaneous route for patients receiving an oral anticoagulant because this route is thought to induce fewer hemorrhagic side effects. Our aim is to assess the safety of intramuscular administration of influenza vaccine in patients on oral anticoagulation therapy. DESIGN: Randomised, controlled, single blinded, multi-centre clinical trial. SETTING: 4 primary care practices in Barcelona, Spain. PARTICIPANTS: 229 patients on oral anticoagulation therapy eligible for influenza vaccine during the 2003-2004 season. INTERVENTIONS: intramuscular administration of influenza vaccine in the experimental group (129 patients) compared to subcutaneous administration in the control group (100 patients). PRIMARY OUTCOME: change in the circumference of the arm at the site of injection at 24 hours. SECONDARY OUTCOMES: appearance of local reactions and pain at 24 hours and at 10 days; change in INR (International Normalized Ratio) at 24 hours and at 10 days. Analysis was by intention to treat using the 95% confidence intervals of the proportions or mean differences. RESULTS: Baseline variables in the two groups were similar. No major side effects or major haemorrhage during the follow-up period were reported. No significant differences were observed in the primary outcome between the two groups. The appearance of local adverse reactions was more frequent in the subcutaneous administration group (37,4% vs. 17,4%, 95% confidence interval of the difference 8,2% to 31,8%). CONCLUSION: This study shows that the intramuscular administration route of influenza vaccine in patients on anticoagulant therapy does not have more side effects than the subcutaneous administration route.

Communicable diseases in the immigrant population attended to in a tropical medicine unit: epidemiological aspects and public health issues.

For geographical and historical reasons, Spain is receiving an increasing number of immigrants. The aim of this study was to evaluate some epidemiological aspects and the main public health issues of communicable diseases in Barcelona's immigrant population. From 2001 to 2004, a population of immigrants from tropical, subtropical regions and Eastern Europe was attended to in our centre. Each patient was offered a complete screening for tropical and common diseases. The prevalence and demographical characteristics of eight diseases with a potential risk of transmission in our setting were studied: latent and active tuberculosis, syphilis, human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV), Chagas disease, Giardia intestinalis and Entamoeba histolytica/Entamoeba dispar. In all, 2464 immigrants mainly from sub-Saharan Africa were seen. Among the patients who underwent the screening, 46.5% had a positive tuberculin skin test (>or=10 mm), incidence of active tuberculosis was 324.7/100,000 immigrants in the period of the study, 6.4% had a positive syphilis serology, 7.7% had a positive HBsAg, 3.1% had a positive serology for HCV and 2.8% were HIV positive, 41 patients from Latin America with risk factors for American Trypanosomiasis were screened for Chagas disease by immunofluorescence assay and 34% had a positive result; 5.4% of stools parasitological tests were positive for G. intestinalis; 4.2% for E. histolytica/E. dispar. Communicable diseases in immigrant population could lead to emerging and re-emerging infections in the European Union with important issues for public health. European countries may have to establish guidelines for screening of infectious diseases in immigrants from low-income countries.
