An assessment of the readability of online material related to fluoride.

Community water fluoridation has been deemed one of the greatest public health achievements, yet it remains a controversial topic. As those who are concerned about the benefits and safety of community water fluoridation are likely to turn to the Internet to find information, it is important to know the ease with which a person can read popular materials online. The aim of this study was to assess the readability levels of pro- and anti-fluoride articles on the Internet. Using a highly-recommended readability site, the first 100 articles garnered from websites in a Google were analyzed for a multitude of scores on popular readability tests. Of the 100 articles analyzed, 71 were deemed to be pro-fluoride, and 29 were anti-fluoride. Anti-fluoride materials were more readable across all scores when compared to the pro-fluoride materials. It is critical for consumers to be aware of the credibility of the health information they are reading and to be educated on how to determine if a website or source is reliable, especially when information is conflicting. It is also critical that health associations and other websites devoted to public health promotion develop and provide more accessible health information in terms of readability.

Violence depicted in advertisements on LinkNYC kiosks in Manhattan, New York City.

Violence has a profound negative impact on the lives of youth. Exposure to violence may be a precursor to violence later in life. The purpose of this study was two-fold: (1) to estimate the prevalence of violence depicted in advertisements on LinkNYC kiosks in Manhattan, NYC, and (2) to determine if violent advertising varied based on the median annual income of the zip code in which the kiosk was located. This cross-sectional study involved observations of advertisements on 100 LinkNYC kiosks that were selected randomly from 500 that were listed in Manhattan, NYC. The frequency and type of violent depictions were recorded. The kiosks were grouped into quartiles of median annual income (1) $40,782 and below (2) $40,783 to $86,801 (3) $86,802 to $105,500 and (4) $105,501 and above. Of the 2025 total advertisements observed, including duplicates, a total of 190 (9.4%) included violent content. These 190 advertisements were observed on 68 of the 100 kiosks and included 339 depictions of violence. The overwhelming majority (n = 136; 71.6%) of violent depictions were for movies. There were significant differences in the frequency of violent content based on income quartiles, χ2 (3, n = 190) = 19.00, p < 0.001. The highest two income quartiles had fewer violent advertisements than would be expected and the lowest quartile had more violent advertisements than expected. Symbols of violence were the most frequent type of violence portrayed observed in 85% of the violent advertisements observed (n = 161). Weapons, crime and fighting were observed in 5-11% of the advertisements. Our study suggests that greater alignment between the city's aims to improve community health and reduce health disparities and advertising policies on LinkNYC warrants consideration.

Price, promotion, and availability of nutrition information: a descriptive study of a popular fast food chain in New York City.

Legislation in NYC requires chain restaurants to post calorie information on menu boards in an effort to help consumers make more informed decisions about food and beverage items they are purchasing. While this is a step in the right direction in light of the current obesity epidemic, there are other issues that warrant attention in a fast food setting, namely the pricing of healthy food options, promotional strategies, and access to comprehensive nutrition information. This study focused on a popular fast-food chain in NYC. The study's aims were threefold: (1) to determine the cost differential between the healthiest meal item on the chain's general menu and meal items available specifically on a reduced cost menu for one dollar (US$1.00); (2) to identify and describe the promotions advertised in the windows of these restaurants, as well as the nutrition content of promoted items; and (3) to ascertain availability of comprehensive nutrition information to consumers within the restaurants. We found the healthiest meal item to be significantly higher in price than less nutritious meal items available for $1.00 (t=146.9, p<.001), with the mean cost differential equal to $4.33 (95% CI: $4.27, $4.39). Window promotions generally advertised less healthful menu items, which may aid in priming customers to purchase these versus more healthful options. Comprehensive nutrition information beyond calorie counts was not readily accessible prior to purchasing. In addition to improving access to comprehensive nutrition information, advertising more of and lowering the prices of nutritious options may encourage consumers to purchase healthier foods in a fast food setting. Additional research in this area is needed in other geographic locations and restaurant chains. 

Promoting healthy vision in students: progress and challenges in policy, programs, and research.

BACKGROUND: An estimated 1 in 5 American children has a vision problem. Children living in poor urban environments have twice the normal rate of vision problems. Uncorrected vision problems can worsen over time and result in permanent vision loss. Early detection and treatment of vision problems is therefore essential in optimizing children's health and development. Federal-, state-, and school-based prevention efforts continue to evolve to identify and serve children with vision problems. METHODS: Review of current literature on (1) major vision problems among children, (2) unique problems faced by low-income children with poor vision, and (3) the rise in health policy and program efforts to support the goal of healthy vision for each child. The preliminary relationship established between vision and academic performance is also discussed. RESULTS: Low-income children have a disproportionate amount of vision problems and face several barriers to acquiring vision care. Varied actions among states include legislation requiring screening and follow-up before entry into elementary school. CONCLUSIONS: States and schools can take concrete steps to increase the number of children identified and treated for vision problems. Health policy and programs should also address common barriers to children receiving and wearing their glasses at home and in the classroom. Further research is necessary to assess the relationship between children's vision and educational outcomes. To the extent that vision is associated with academic success, policies and programs can be shaped to address the achievement gap that exists among our nation's youth and to support the goal of healthy vision for each child.
