“…First, counting only newly treated patients increased the sensitivity of demonstrating a change in prescribing. 7 Second, combining the effects of a series of letters created a larger sample than would have been available for any 1 letter.…”

“…Letters #7 and #8 on antihypertensive therapy were a special case. 7 They formed a 2-part series and were mailed 10 weeks apart. They were treated as a single intervention; the control group received Letter #7 8 weeks after the intervention group received Letter #8.…”

“…In 1998 we reported that 2 letters on the treatment of primary hypertension did not produce a statistically significant change in prescribing. 7 Here we report findings from a combined randomized trial of the impact of 12 of the first 20 issues of the Therapeutics Letter, which were distributed between October 1994 and December 1997. This combined analysis was undertaken to measure the series' overall impact on prescribing to newly treated patients and to provide evidence of the effectiveness of these interventions in a Canadian setting.…”

“…By serving as credible sources in media coverage, health professionals serve as role models and public educators (Chapman, 2004). Perhaps because healthcare professionals identify with credible spokespeople in media coverage of health issues, media coverage has also been demonstrated to influence practices such as prescribing patterns (Maclure, Dormuth, Naumann, McCormack, Rangno, Whiteside et al, 1998). In other words, the influences on practicing professionals include their initial training, continuing professional education activities such as conferences and journal clubs, outreach by industry representatives, and mass media coverage.…”

In industrialized societies, more than one in three dogs as well as people currently qualify as overweight or obese. Experts in public health expect both these figures to rise. While clinical treatment remains important, so are public perceptions and social norms. This article presents a thematic analysis of English-language mass media coverage on canine obesity from 2000 through 2009, and compares these results with a thematic analysis of articles on canine obesity in leading veterinary journals during the same time period. Drawing on Giddens' theory of structuation, articles that emphasised individual agency, environmental structure or both as contributors to canine obesity were identified. Comparisons with weight-related health problems in human populations were virtually absent from the veterinary sample. While such comparisons were almost always present in the media sample, veterinarians and other animal welfare spokespeople were quoted in ways that emphasized the agency of individual owners over structural influences. Now that weight gain and obesity have been established as a pressing animal welfare problem, these results suggest a need for research and for interventions such as media advocacy that emphasizes intersections between animal-owner agency and socio-environmental determinants, and connections between animal welfare and human health.

ATTERNS OF HORMONE THERAPYuse among postmenopausal women in the United States ideally should reflect known risks and benefits. However, definitive information on these risks and benefits was lacking until recently. The Heart and Estrogen/Progestin Replacement Study (HERS) 1 and HERS follow-up (HERS II) 2 concluded that postmenopausal hormone therapy with combination oral estrogen/progestin offered no cardiovascular disease benefit among women with established disease. The estrogen plus progestin trial of the Women's Health Initiative (WHI) 3 demonstrated that hormone therapy with an estrogen/ progestin combination caused increased risk of breast cancer and cardiovascular disease in postmenopausal women. These findings from randomized trials contrast with prior observational studies that suggested cardiovascular benefits. [4][5][6] Based on the quality of recent data, new guidelines recommend against routine hormone therapy use for chronic conditions, 7 and current users have been advised to taper doses toward discontinuation. 8,9 Prior studies from nationally representative databases showed that in 1975, hormone therapy prescriptions peaked at 30 million. [10][11][12] Prescriptions subsequently declined to approximately 15 million in the early 1980s as evidence emerged showing an increased risk of endometrial cancer with unopposed estrogen use. [10][11][12] Prescription growth resumed as progestins were prescribed in combination with estrogen, and prescriptions for hormone therapy reached 36 million in 1992, representing approximately 6 million women and 17% of women older than 50 years. 10 More re-
