Attention-deficit hyperactivity disorder is associated with risky and unhealthy behaviours among adolescents.

Objectives: Attention-deficit hyperactivity disorder (ADHD) is highly prevalent among adolescents globally, particularly in Israel. This study aimed to evaluate associations between ADHD and engagement in risky/unhealthy behaviours among adolescents.

Study Design: Cross-sectional study.

Pfizer COVID19 vaccine is not associated with acute cardiovascular events excluding myocarditis- a national self-controlled case series study.

Background: Despite publications assuring no increased risk for acute cardiovascular events (excluding myocarditis) and sudden death following administration of COVID19 vaccines, these issues still stir much public ado. We assessed the risk for acute cardiovascular events that require hospitalization (excluding myocarditis) and for mortality in the short-term following administration of the second dose of the Pfizer COVID19 vaccine in Israel.

Methods: Using a self-controlled case series (SCCS) study design and national databases, all second-dose vaccinees, who had not been diagnosed with COVID19 and who had an acute cardiovascular event (acute myocardial infarction/acute stroke/acute thromboembolic event) that required hospitalization in the 60 days following vaccine administration between Jan 11th, 2021 and Oct 31st 2021, were included.

Exposure to Holocaust is associated with chronic morbidity in older adults-Results from national health and nutrition surveys.

Background: Although studies have suggested that Holocaust survivors are more likely than their non-Holocaust-exposed counterparts to suffer from mental and chronic morbidity, methodology differences and potential confounders often compromise result replicability and external validity. We examined associations between Holocaust exposure and chronic morbidity, as well as overall risk of mortality.

Methods: Sociodemographic, health-related behavior and nutritional-intake data from two representative National Health and Nutrition Survey Ages 65 and Over-the 2005-2006 MABAT ZAHAV 1 (MZ1) and the 2014-2015 MZ2, including face-to-face interviews and anthropometric measurements-were analyzed.

Attention-deficit hyperactivity disorder is associated with disordered eating in adolescents.

Aim: Attention-deficit hyperactivity disorder (ADHD) and disordered eating (DE) are both highly prevalent among adolescents, but their relationship is understudied. This study examines their possible association in a nationally representative sample of adolescents.

Methods: Participants in the Israeli Youth Health and Nutrition Survey (2015-2016), a cross-sectional, school-based study, completed self-administered questionnaires, including the SCOFF questionnaire, and underwent anthropometric measurements.
