OBJECTIVE To investigate sexual activity as a trigger of myocardial infarction and the potential effect modification of physical fitness. DESIGN A case-crossover study nested in the Stockholm Heart Epidemiology Programme (SHEEP). SETTING Stockholm County from April 1993 to December 1994. PATIENTS All patients with a first episode of non-fatal acute(More)
OBJECTIVE Our objectives were to study anger as a trigger of acute myocardial infarction (MI) and to explore potential effect modification by usual behavioral patterns related to hostility. METHODS This study was a case-crossover study within the Stockholm Heart Epidemiology Program. Exposure in the period immediately preceding MI was compared with(More)
AIMS To investigate the triggering effects of alcohol, illegal substances and major classes of prescribed psychotropic drugs on criminal violence. DESIGN A case-crossover design, using each subject as its own control. SETTING AND PARTICIPANTS A consecutive sample of 133 violent offenders was recruited from a forensic psychiatric evaluation unit and a(More)
BACKGROUND Sudden emotions may interfere with mechanisms for keeping balance among the elderly. The aim of this study is to analyse if emotional stress and specifically feelings of anger, sadness, worries, anxiety or stress, can trigger falls leading to hip or pelvic fracture among autonomous older people. METHODS The study applied the case-crossover(More)
OBJECTIVES Research has shown that individuals reporting a low level of adjustment latitude, defined as having few possibilities to temporarily adjust work demands to illness, have a higher risk of sick leave. To what extent lack of adjustment latitude influences the individual when making the decision to take sick leave is unknown. We hypothesize that ill(More)
To study possible triggering of first events of acute myocardial infarction by heavy physical exertion, the authors conducted a case-crossover analysis (1993-1994) within a population-based case-referent study in Stockholm County, Sweden (the Stockholm Heart Epidemiology Program). Interviews were carried out with 699 myocardial infarction patients after(More)
STUDY OBJECTIVES Recent changes in labour market conditions and in the organisation of work in developed societies have increased exposure to work related stress. The question is whether this also implies an increased risk of myocardial infarction, either through the triggering effect of acute stress, or through accumulation of stress over several months.(More)
BACKGROUND There is growing epidemiological evidence that opioids may increase the risk of unintentional injuries and it is plausible that the time of initiation is most critical in that respect. Studies on fall-related injuries remain few, limited and mostly focused on specific groups of elderly patients. OBJECTIVE The objective of this study was to(More)
BACKGROUND The simultaneous use of several medications is an important risk factor for injurious falls in older people. The aim of this study is to investigate the effect of the number of medications dispensed to elderly persons on fall injuries and to assess whether this relationship is explained by individual demographics, health habits and health status.(More)
BACKGROUND Among senior drivers, benzodiazepines (BZDs) have a documented effect on the risk of road traffic crashes (RTCs). It remains unclear however if BZDs play the same role when considering marital status. Therefore, we aimed to investigate the role of marital status in the association between BZD use and injurious RTCs among senior drivers. METHODS(More)
