The effects of traffic light labelling versus cartoon labelling on food and beverage purchases in a children's hospital setting.

This study's purpose was to examine changes in healthy and unhealthy items purchased following the implementation of traffic light and cartoon labelling in a small retail food venue (Café Bay) in a children's hospital in eastern North Carolina. Between October 2015 and March 2016, daily food and beverage sales from Café Bay were obtained during baseline, traffic light labelling, a washout period, cartoon labelling (on healthy foods only) and a final washout period. Pearson chi-squared tests and multiple linear regressions were used to examine effects of labelling strategies, controlling for the holidays. In unadjusted analyses, traffic light labelling was associated with significant decreases in purchases of unhealthy items purchased, while cartoon labelling was associated with increases in unhealthy items purchased. In adjusted linear regression analysis, traffic light labelling was associated with fewer unhealthy purchases and thus may have potential to decrease the amount of unhealthy items purchased in a children's hospital food retail venue.

Public support for the use of newborn screening dried blood spots in health research.

OBJECTIVES: The level of support among Michigan adults for the use of residual newborn screening dried blood spots (DBS) was investigated. METHODS: We analyzed data from 4 questions on the 2008 Michigan Behavioral Risk Factor Surveillance System (n = 3,108). The questions asked about general support for the use of DBS for research and for research investigating childhood diseases, adult diseases and diseases related to environmental exposures. RESULTS: The majority of adults (72.3%) favored the use of DBS for research intended to benefit the health of residents. With more question specificity, a higher proportion of adults (84.2%-86.8%) were found to favor the use of DBS for research, and a lower proportion had no opinion. The odds of favoring use were higher among those who were younger, female, white, healthy, or with at least a high school degree. CONCLUSIONS: This is the first population survey of adult attitudes regarding use of DBS for different types of health research, with results showing considerable public support. The findings are being used in community outreach efforts and highlight the need to investigate opposition in vulnerable populations.

Validity of a household gun question in a telephone survey.

The validity of self-reported data on the presence of guns in the home obtained in a telephone survey was assessed in samples of households where a hunting license had been purchased or a handgun registered. The survey was conducted among a random sample of Ingham County, MI, residents who had purchased a hunting license between April 1990 and March 1991 and among those registering a handgun during 1990. A third study sample was selected from the county's general adult population using a random digit dialing method. The interviews were conducted between November 1991 and January 1992. The proportion of respondents who reported that at least one gun was kept in their household was 87.3 percent among handgun registration households and 89.7 percent among hunting license households. In the survey of the general population of the county, approximately one-third of the respondents reported keeping a gun in the household, 67 percent of them for hunting and 23 percent for safety. Despite some limitations, the data indicate that a question on gun presence in a household can be used in a in a telephone survey.
