Effect of Social Media Characteristics on Perceptions of Alcohol-Branded Social Media Content

Background: Alcohol advertising has recently expanded onto social networking sites (SNSs), which allows users to interact with alcohol ads through user engagement features (e.g. Likes or Shares) and user-generated comments. Few studies have evaluated alcohol advertising on SNSs or investigated how ad interactivity may influence ad perceptions. Two inter-related studies were conducted to answer these questions. Methods: In Study 1, alcohol advertising posted on Facebook by Budweiser and Bud Light were evaluated for compliance with a self-regulated alcohol advertising code and for thematic content. User-generated comments written in response to these ads were also evaluated. The results of this study were used to inform Study 2, a 2(within) x 2(between) x 2(between) factorial randomized trial. Participants (n=120) viewed four pre-selected Facebook ads, of which two were compliant and two were non-compliant with a self-regulated alcohol advertising code. Participants also viewed real-world high or low user engagement values and real-world pro- or anti-drinking user-generated comments. Ad appeal, drinking intentions, and individual user engagement were measured after viewing each ad. The results were analyzed using hierarchical linear models. Results: In Study 1, 82% of the ads contained 1 or more violations of a self-regulated alcohol advertising code, and 78% of the ads contained one or more content areas previously associated with code violations. Forty-seven percent of the user-generated comments were positive towards the product or drinking. In Study 2, ads non-compliant with a self-regulated alcohol advertising code scored higher on emotional appeal (p=0.004) while compliant ads scored higher on informational (p\u3c0.001) and source appeal (p=0.034). Pro-drinking user-generated comments significantly increased drinking intentions and individual user engagement. Discussion: Self-regulation has failed to prevent potentially harmful content from appearing in Budweiser and Bud Light advertising posted on Facebook. Non-compliance with existing self-regulated alcohol advertising codes was associated with increased emotional appeal, which may result in the ads being remembered more often and recalled more swiftly. Pro-drinking user-generated comments were associated with increased drinking intentions and increased individual user engagement, both of which are associated with increased alcohol consumption. New regulations may be needed to limit alcohol ad content and the influence of user-generated comments

Industry Self-regulation of alcohol marketing: A systematic review of content and exposure research

BACKGROUND AND AIMS: With governments increasingly relying on the alcohol industry's self-regulated marketing codes to restrict alcohol marketing activity, there is a need to summarize the findings of research relevant to alcohol marketing controls. This paper provides a systematic review of studies investigating the content of, and exposure to, alcohol marketing in relation to self-regulated guidelines. METHODS: Peer-reviewed articles were identified through four literature search engines: SCOPUS, Web of Science, PubMed, and PsychINFO. Non-peer reviewed reports produced by public health agencies, alcohol research centers, non-governmental organizations, and government research centers were also identified. 96 publications met the inclusion criteria. RESULTS: Of the 19 studies evaluating a specific marketing code and 25 content analysis studies reviewed, all detected content that could be considered potentially harmful to children and adolescents, including themes that strongly appeal to young men. Of the 57 studies of alcohol advertising exposure, high levels of youth exposure and high awareness of alcohol advertising were found for television, radio, print, digital, and outdoor ads. Youth exposure to alcohol advertising has increased over time, even as greater compliance with exposure thresholds has been documented. CONCLUSIONS: Violations of the content guidelines within self-regulated alcohol marketing codes are highly prevalent in certain media. Exposure to alcohol marketing, particularly among youth, is also prevalent. Taken together, the findings suggest that the current self-regulatory systems that govern alcohol marketing practices are not meeting their intended goal of protecting vulnerable populations

Disparities in Infant Mortality Due to Congenital Anomalies on Guam

In the 1970's and 1980's, there were large inter-village disparities in infant mortality due to congenital anomalies on Guam. A village-level analysis was conducted to determine if these disparities can be explained by behavioral (ie, median age of village females, village fertility ratio), structural (ie, population density, persons per household, single mother households per village, married females per village), and environmental (ie, living in a village where Agent Orange (AO) spraying was conducted) factors. Village-level data for live births and infant mortality due to congenital anomalies (1970–1989) was collected from Guam's Office of Vital Statistics. Data on median age of village females, village fertility ratio, population density, persons per household, single mother households, and married females were obtained from the 1980 US Census. Estimates of village-level AO use were provided through personal communications, and villages were dichotomized into AO and non-AO spray areas. Village location was classified by usual residence of the mother. Linear regression was used to determine associations between infant mortality due to congenital anomalies and the behavioral, structural, and environmental factors. The association between AO spray area and infant mortality due to congenital anomalies was statistically significant under univariable (B [95%CI] = 1.88 [0.64,3.11], P = .005) and multivariable conditions (B [95%CI] = 2.02 [0.08,3.96], P = .042). These results suggest that infants born to mothers whose usual residence was in an AO spray area on Guam are at an increased risk of mortality due to congenital anomalies. Further studies using individual-level data are needed to validate these results
