BACKGROUND: Very little is known about how incarceration influences a person's weight in Canada. We sought to determine how inmates' weights change during their incarceration in Canadian federal penitentiaries. METHODS: We performed a retrospective, longitudinal cohort study to examine weight change in Canadian federal penitentiaries. To participate, inmates had to have been incarcerated for at least 6 months at the time of the study. Current anthropometric data were measured or taken from medical records, then compared with anthropometric data from the beginning of incarceration (mean follow-up of 5...

BACKGROUND: Colonoscopy is used widely, but its quality is highly variable, which may adversely affect patients. Research and quality-improvement initiatives in a variety of jurisdictions have sought to address this issue, often supported by the use of health administrative data. As these data are generally not collected for these purposes, it is critical to measure their validity before use. The aim of this study was to validate health administrative data definitions for 5 key colonoscopy elements through comparison to the clinical record...
