Media Flight Schedules and Seasonality in Relation to Quitline Call Volume.

CONTEXT: Given the high profile, cost, and vulnerability to budget cuts of mass-reach health education campaigns, researchers have cited the need for media buying strategies. OBJECTIVE: The objective of the current study is to fill a gap in the literature by comparing the impact of media flight schedule types in relation to tobacco quitline call volume. DESIGN: The retrospective study was designed to determine whether type of media flight schedule (eg, flighting, continuous, pulsing) impacted number of calls to the Maine Tobacco Helpline, while accounting for number of gross rating points (GRPs), seasonality, holidays, and other factors. SETTING: Maine has 3 designated market areas (DMAs): Portland/Auburn, Bangor, and Presque Isle. MAIN OUTCOME MEASURES: Daily call volume was matched with weekly GRPs. METHODS: A negative binomial regression model was created to examine the relationship among media flight schedules, number of GRPs, and call volume. Gross rating points reflect national networks and local cable TV media buys. A second model examined the association between GRP dose levels and call volume. RESULTS: The number of GRPs was a significant predictor of call volume (P < .001). Weekly number of GRPs within a media flight schedule was the most important indicator for potential effectiveness. Weekly low-dose GRPs were not effective in increasing calls, indicating a minimum threshold. For every 250 GRPs, 29% (or 73) more calls per week were attributed to the media campaigns (P < .001). Weekly quitline call volume was 21% (or 53 calls) lower during the weeks of Christmas, US Thanksgiving, and US Independence Day. CONCLUSION: Type of media flight schedule should be considered in the context of purchasing sufficient weekly, as well as quarterly, rating points to increase tobacco quitline call volume. In addition, our study is the first to quantify and report on lower tobacco quitline call volume during several US holidays.

Peer Crowd Identification and Adolescent Health Behaviors: Results From a Statewide Representative Study.

PURPOSE: Peer crowds are macro-level subcultures that share similarities across geographic areas. Over the past decade, dozens of studies have explored the association between adolescent peer crowds and risk behaviors, and how they can inform public health efforts. However, despite the interest, researchers have not yet reported on crowd size and risk levels from a representative sample, making it difficult for practitioners to apply peer crowd science to interventions. The current study reports findings from the first statewide representative sample of adolescent peer crowd identification and health behaviors. METHODS: Weighted data were analyzed from the 2015 Virginia Youth Survey of Health Behaviors ( n = 4,367). Peer crowds were measured via the I-Base Survey™, a photo-based peer crowd survey instrument. Frequencies and confidence intervals of select behaviors including tobacco use, substance use, nutrition, physical activity, and violence were examined to identify high- and low-risk crowds. Logistic regression was used to calculate adjusted odds ratios for each crowd and behavior. RESULTS: Risky behaviors clustered in two peer crowds. Hip Hop crowd identification was associated with substance use, violence, and some depression and suicidal behaviors. Alternative crowd identification was associated with increased risk for some substance use behaviors, depression and suicide, bullying, physical inactivity, and obesity. Mainstream and, to a lesser extent, Popular, identities were associated with decreased risk for most behaviors. CONCLUSIONS: Findings from the first representative study of peer crowds and adolescent behavior identify two high-risk groups, providing critical insights for practitioners seeking to maximize public health interventions by targeting high-risk crowds.
