background: population attributable fraction (paf) is one of the most practical measures for estimating the burden of risk factors with some challenges in its calculation. cardiovascular disease (cvd) is the first cause of death worldwide and the estimation of accurate pafs for cvd risk factors is of great importance in conducting preventive strategies. our aim was to estimate the pafs of cvd r...

OBJECTIVES To determine the prevalence of proper fencing around outdoor swimming pools among US households and to describe this fencing in relation to demographic and other household factors. To estimate the number of drownings among children <5 years of age that might be prevented by having proper fencing around all residential pools in the United States. METHODS A 1994, randomly dialed nati...

BACKGROUND Childhood immunisation is recognised worldwide as an essential component of health systems and an indispensable indicator of quality of care for vaccine-preventable diseases. While performance of immunisation programmes is more commonly measured by coverage, ensuring that every child is immunised at the earliest/appropriate age is an important public health goal. This study therefore...

We investigated the relation between parental education and dementia in the United States. Participants in the Aging, Demographics, and Memory Study were included, with information regarding parental education obtained from the Health and Retirement Study. The odds of dementia in elderly Americans whose mothers had less then 8 years of schooling were twice (95% CI, 1.1-3.8) that of individuals ...

BACKGROUND Indigenous peoples in Canada have higher prevalence of modifiable risk factors for Alzheimer's disease (AD). The relative importance of these risk factors on AD risk management is poorly understood. METHODS Relative risks from literature and prevalence of risk factors from Statistics Canada or the First Nations Regional Health Survey were used to determine projected population attr...

Population attributable risk (PAR) or etiologic fraction is the proportion of a disease that could be prevented by elimination of a causal risk factor from the population. PAR is likely to be a function of time because both the prevalence of a risk factor and its effect on exposed individuals may change over time, as may the underlying risk of disease. In cohort studies with a wide range of fol...

OBJECTIVES To investigate the temporal trends in the mortality burden attributed to overweight and obesity in Canada between 1985 and 2000. DESIGN Overweight and obesity prevalence data from six cross-sectional national population surveys, including the 1985 and 1990 Health Promotion Surveys, 1994, 1996 and 1998 National Population Health Surveys, and 2000 Canadian Community Health Survey, in...

OBJECTIVE To estimate the impact of employee alcohol and drug use on crashes in the transit industry from 1995-2000. DESIGN Secondary analysis of federally mandated post crash and random alcohol and drug testing results. SETTING The US transit industry. SUBJECTS Transit industry employees. MAIN OUTCOME MEASURES Relative risk (RR), population attributable risk (PAR), and population attri...
