BACKGROUND: In most previous studies the association between number of teeth and cardiovascular diseases has been found to be stronger among younger age groups than in older age groups, which indicates that age may modify the association between number of teeth and cardiovascular diseases. We investigated the association between tooth loss and atherosclerotic vascular diseases such as myocardial infarction and stroke in a homogeneous elderly population. The study population was comprised of a subpopulation of 392 community-living elderly people who participated in the population-based Kuopio 75+ study. The data were collected through an interview, a structured clinical health examination and from patient records. The main outcome measures were a history of diagnosed myocardial infarction and diagnosed ischemic stroke. Prevalence proportion ratios (PPR) were estimated using generalised linear models. RESULTS: Edentate subjects had a weakly, statistically non-significantly increased likelihood of a history of myocardial infarction and ischemic stroke compared with dentate subjects. Those with a large number of teeth had a slightly, but not statistically significantly increased likelihood of a history of myocardial infarction and ischemic stroke compared with those with a small number of teeth. CONCLUSION: These data did not show evidence that total or partial tooth loss would be associated with atherosclerotic vascular diseases such as myocardial infarction and ischemic stroke among an elderly population aged 75 years or older.
What lies behind relief and worsening of asthma symptoms? A register-based study of adults with asthma and other chronic obstructive pulmonary diseases in Finland.
AIMS: To examine how subjects with relief or worsening of asthma symptoms differ in terms of gender, age, severity and duration of asthma, comorbidity, and difficulties with medication and daily life. METHODS: A postal inquiry among a sample of 6000 adults with clinically diagnosed asthma and/or other chronic obstructive pulmonary diseases. RESULTS: Relief of asthma symptoms over a 12-month period was associated with a recent asthma diagnosis, within five years, in both sexes. Lack of current smoking and lack of problems in using anti-asthmatic treatment were associated with a positive outcome in men, and mild asthma and living alone associated with a positive outcome in women. Severe and moderate asthma predicted worse symptoms in both sexes, as did other obstructive pulmonary diseases, living alone, and medication problems amongst men. CONCLUSIONS: Patients with asthma should be cared for comprehensively, requiring consideration of both clinical and psychosocial factors that can modify the course of the disease.
