Using a Betabinomial distribution to estimate the prevalence of adherence to physical activity guidelines among children and youth
Population health surveys routinely use activity monitors to measure physical activity. This results in a finite number of days when respondents wear the device and accumulate enough physical activity to meet a predetermined level at which the day will be deemed active. In large samples, a minimum number of wear-days for a minimum number of hours is required in order to have a valid representation of a respondent’s activity level. This yields a different number of valid days for each respondent. Each combination of active and valid days can then be used to calculate a probability of adherence to a certain frequency of active days (for example, physical activity guidelines).

Active travel and adults’ health: The 2007-to-2011 Canadian Health Measures Survey
by Richard Larouche, Guy Faulkner and Mark S. Tremblay
Lack of physical activity is strongly associated with a range of negative health consequences for adults. For instance, insufficient physical activity causes an estimated 9% of premature mortality worldwide and is related to 6% to 10% of the burden of diseases from coronary heart disease, type 2 diabetes, breast cancer and colon cancer.

Differences in cancer survival in Canada by sex
Studies in Europe, the United States, and Korea have recently reported that women have an advantage over men in surviving a diagnosis of cancer. A biological advantage mediated through sex hormones has been proposed. Another possibility is that the difference may, in part, reflect women’s generally healthier attitudes and behaviours. Whether the explanation is biological or cultural, or a combination of the two, has yet to be determined. Analyses of data from population-based cancer registries may be used to reduce, or at least better understand, sex-specific disparities in cancer prognosis.
