Comparative Study Clinical TrialCommercially available pedometers: considerations for accurate step counting.
Many commercially available pedometers undercount, especially at slower speeds. We examined the effects of age, obesity, and self-selected walking speed on pedometer accuracy. We also compared the accuracy of piezoelectric and spring-levered pedometers at slow walking speeds. ⋯ Accuracy of all pedometers tested exceeded 96% at speeds 3.0 MPH, but decreased at slower walking speeds. In individuals that naturally ambulate at slower walking speeds (e.g., elderly), we recommend the use of more sensitive (e.g., piezoelectric) pedometers.

Physicians taught as residents to conduct smoking cessation intervention: a follow-up study.
The influence of residency training on use of smoking cessation intervention (SCI) in future practice is unexamined. ⋯ To expand use of best SCI, residencies must ensure physicians use SCI skills, and health care systems must provide resources to facilitate intervention.

Colorectal cancer screening: practices and opinions of primary care physicians.
The Canadian Task Force on Preventive Health Care (CTFPHC), in 2001, concluded that there is good evidence to include annual or biennial fecal occult blood testing (FOBT) and fair evidence to include flexible sigmoidoscopy in the periodic health examination of asymptomatic adults more than 50 years of age. ⋯ Although supportive of colorectal cancer screening of average-risk patients, few physicians recommend screening for the majority of their patients. Clarification of inconsistencies between guidelines, resource issues, and the availability of efficacious screening tests is required for wider acceptance of the new Canadian guideline.

Predictors of sun protection in northern Australian men with a history of nonmelanoma skin cancer.
It is important to understand what predicts regular use of sun protection in men susceptible to skin cancer. ⋯ Men who adequately protect themselves from the sun and who have better attitudes to sun exposure were more often those with a high level of negative experience with skin cancer. Therefore, the sun protection attitudes and behaviors of some men may only improve after significant sun damage. This study recommends that the use of appropriate sun protective clothing should be made mandatory for all who work outdoors in high-sun-exposure occupations.
