Cross-national time trends in adolescent alcohol use from 2002 to 2014.

Background: Adolescent alcohol consumption is a major public health concern that should be continuously monitored. This study aims (i) to analyze country-level trends in weekly alcohol consumption, drunkenness and early initiation in alcohol consumption and drunkenness among 15-year-old adolescents from 39 countries and regions across Europe and North America between 2002 and 2014 and (ii) to examine the geographical patterns in adolescent alcohol-related behaviours.

Methods: The sample was composed of 250 161 adolescents aged 15 from 39 countries and regions from Europe and North America.

Association of alcohol control policies with adolescent alcohol consumption and with social inequality in adolescent alcohol consumption: A multilevel study in 33 countries and regions.

Background Previous research found inconsistent associations between alcohol control policies and socioeconomic inequality with adolescent drinking outcomes. This study expands the focus beyond individual associations to examine whether a combination of policies is related to socioeconomic inequality in adolescent drinking outcomes and whether this relationship varies across survey years. Methods Multilevel modelling of 4 waves of repeat cross-sectional survey data (2001/02, 2005/06, 2009/10, and 2013/14) from the Health Behaviour in School-aged Children (HBSC) study was carried out.

[Trends in alcohol consumption among school-aged adolescents in Spain (2010-2018)].

Objective: To analyze trends in beer, wine, and distilled spirits consumption, as well as drunkenness among school-aged adolescents in Spain from 2010 to 2018 by sex and age.

Method: The sample is composed of 35,310 adolescents aged 15 to 18. The data is representative of the adolescent school population in Spain in 2010, 2014, and 2018.

Trends in tobacco use among adolescents in Spain (2002-2018).

Smoking is the single greatest preventable cause of death in the world today. Adolescence is the developmental period during which smoking is most commonly initiated and addiction is likely to happen. The aim of this study is to examine trends in tobacco use among school-aged adolescents in Spain from 2002 to 2018 by sex and age.

Effects of culture medium and formulation on the larvicidal activity of the mosquito pathogen Lagenidium giganteum (Oomycetes: Lagenidiales) against Aedes aegypti.

In this work, we examined the production of infective zoospores of Lagenidium giganteum in four culture media, and the larvicidal activity of the cultures was determined against Aedes aegypti larvae, as well as the effect of polymer encapsulation. Medium containing sunflower seed extract showed the greatest production of zoospores, 5.92×10(6) zoospores/ml after six days of fermentation at 25±2°C and 150rpm shaking.
