Using theory to identify beliefs associated with support for policies to raise the price of high-fat and high-sugar foods

Public policies designed to dramatically raise the price of high-fat and high-sugar foods have received substantial attention from researchers and the media. Although econometric studies suggest that these policies could reduce obesity rates, they are likely to face substantial public opposition. This study used the theory of perceived responsibility and social motivation as a framework to analyze data from a politically diverse convenience sample of 500 adults in upstate New York. The authors examined associations between attribution beliefs and policy support to identify what types of scientific evidence and accompanying messages appear most likely to generate public support for price-raising policies. Results suggest that public health advocates and health communicators could benefit from an increased emphasis on advertising for unhealthy foods as a cause of obesity and the food industry's (manufacturers, advertisers, markets, and restaurants) responsibility for addressing the problem.     

Linking agriculture and health in low- and middle-income countries: an interdisciplinary research agenda

Recent global fluctuations in food prices and continuing environmental degradation highlight the future challenge of feeding a growing world population. However, current dialogues rarely address the relationship between agricultural changes and health. This relationship is traditionally associated with the role of food in nutrition and with food safety, and while these are key interactions, we show in this paper that the relationship is far more complex and interesting. Besides the direct effects of agriculture on population nutrition, agriculture also influences health through its impact on household incomes, economies and the environment. These effects are felt particularly in low- and middle-income countries, where dramatic changes are affecting the agriculture-health relationship, in particular the growth of nutrition-related chronic disease and the associated double burden of under- and over-nutrition. Greater understanding of the negative effects of agriculture on health is also needed. While lengthening food value chains make the chain of influence between agricultural policy, food consumption, nutrition and health more complex, there remain opportunities to improve health by changing agricultural systems. The first challenge in doing this, we suggest, is to improve our capacity to measure the impact of agricultural interventions on health outcomes, and vice versa.     

An unmasking phenomenon in an observational post-licensure safety study of adolescent girls and young women

Our recent experience in a post-licensure safety study of autoimmune conditions following the quadrivalent human papillomavirus vaccine in 189,629 girls and young women ages 9-26 years led us to question the adequacy of the exclusion of Day 0 events to prevent the erroneous association of prevalent conditions with vaccination. Of the 18 confirmed cases of Graves' disease diagnosed in days 1-60 following vaccination, only 6 cases appeared to be truly new onset. Among the remaining 12 cases, 2 cases had abnormal thyroid stimulating hormone or thyroxine labs drawn prior to or on Day 0 but had no documented pre-existing symptoms. The other 10 cases had mention of symptoms of hyperthyroidism referencing a period prior to first HPV-4 dose. This 'unmasking' phenomenon, due to health care visits that include vaccination and new workups of preexisting symptoms, may not be adequately controlled through the exclusion of Day 0 events.     

Clinical effectiveness of pneumococcal polysaccharide vaccine in men: California Men's Health Study

Objective

To examine the effectiveness of pneumococcal polysaccharide vaccine (PPV) among approximately 40,000 community-dwelling men aged 45 years and older in the California Men's Health Study (CMHS) cohort.

Methods

All participants completed an extensive questionnaire at baseline (2002–2003) and were followed for the occurrence of invasive pneumococcal disease (IPD) or all-cause pneumonia hospitalization through the end of 2009. Immunization status and incident IPD and pneumonia cases were ascertained through electronic medical records. The associations between vaccination and IPD or pneumonia hospitalization were assessed using time-dependent Cox proportional models to account for sociodemographics, time-updated vaccination status, and comorbidities.

Results

The median follow-up period of the 39,222 participants was 7.3 years. Among them, 11,902 (30.3%) had received at least one PPV vaccine at baseline and 7653 (19.5%) received their first PPV vaccine during the follow-up. There were 17 pneumococcal bacteremia cases, 647 hospitalized pneumonia cases, and no pneumococcal meningitis cases. The results suggested a reduced risk of pneumococcal bacteremia among men vaccinated at age ≥65 (adjusted hazard ratio [HR]: 0.35; 95% confidence interval [CI]: 0.06–1.91; p = 0.22). PPV vaccination did not show a protective effect against all-cause pneumonia hospitalization (adjusted HR: 1.18; 95% CI: 1.02–1.37, p = 0.03) among men vaccinated before 65 years old, but a moderate protective effect was suggested among men without chronic obstructive pulmonary diseases who were vaccinated after 65 years old (adjusted HR: 0.84; 95% CI: 0.67–1.06, p = 0.15).

Conclusions

The findings in this large cohort of men in Southern California suggested a benefit of PPV for protection against pneumococcal bacteremia among men vaccinated at age 65 years and older. PPV might not provide adequate protection against all-cause pneumonia hospitalization among men.     

Solutions to emergency department 'boarding' and crowding are underused and may need to be legislated

The practice of keeping admitted patients on stretchers in hospital emergency department hallways for hours or days, called "boarding," causes emergency department crowding and can be harmful to patients. Boarding increases patients' morbidity, lengths of hospital stay, and mortality. Strategies that optimize bed management reduce boarding by improving the efficiency of hospital patient flow, but these strategies are grossly underused. Convincing hospital leaders of the value of such solutions, and educating patients to advocate for such changes, may promote improvements. If these strategies do not work, legislation may be required to effect meaningful change.
