As described below, both images and text were coded. Differences between the two magazines also body fat monitors were examined. METHODS The units of sampling for this body fat monitors study were the individual magazines. From 1999 to 2003, Men's Fitness published 60 issues (one per body fat monitors month), while Men's Health published 50 issues (the January/February and July/August issues were combined each year). A sample consisting of 15 issues of each magazine (25% of the population of Men's Fitness and 30% of the population of Men's Health issues published in that time period) was used. Because the contents of magazines may, to some extent, reflect the time of year (for example, summer issues may be more likely to focus on improving physical appearance to look good at the beach), the sampling method was designed to ensure that particular months would not be overrepresented.
