Rationale: The United States is one of only two countries that permit direct-to-consumer advertising (DTCA) of prescription drugs, and many questions remain regarding its effects. Objective: To quantify the association between asthma-related DTCA, pharmacy sales and health care utilization. Methods: Ecological study from 2005 through 2009 using linked data from Nielsen (... more

Authors: Huang J, Zheng R, Chaloupka FJ, Fong GT, Jiang Y.

Background: Few studies have examined the impact of tobacco tax and price policies in China. In addition, very little is known about the differential responses to tax and price increases based on socioeconomic status in China. Objective: To estimate the conditional cigarette consumption price elasticity among adult urban smokers in China and to examine the differential responses to cigarette price increases among groups with different... more

Tob Control. 2015 Jul;24 Suppl 3:iii88-iii93.
Authors: Shang C, Chaloupka FJ, Fong GT, Thompson M, O'Connor RJ.

Background: Recent studies have shown that more opportunities exist for tax avoidance when cigarette excise tax structure departs from a uniform specific structure. However, the association between tax structure and cigarette price variability has not been thoroughly studied in the existing literature. Objective: To examine how cigarette tax structure is associated with price variability. The variability of self-reported prices is... more

Contemp Clin Trials. 2015 Apr 3;42:98-104.

Retaining underserved populations, particularly low-income and/or minority participants in research trials, presents a unique set of challenges. In this paper, we describe initial retention strategies and enhanced retention strategies over time across three childhood obesity prevention trials. Hip... more

Introducation: Earlier initiation of cannabis use is associated with poorer neuropsychological functioning across several domains. Given well-documented sex differences in neuromaturation during adolescence, initiation of cannabis use during this time may affect neuropsychological functioning differently for males and females. Method: In the current study, we examined sex differences in the relationship between age... more

Objectives: Study the effects of the 2011 Malaysian minimum price law (MPL) on prices of licit and illicit cigarette brands. Identify barriers to the MPL achieving positive public health effects. Methods: The International Tobacco Control Project's Southeast Asia survey collected information on Malaysian smokers' cigarette purchases (n=7520) in five survey waves between 2005 and 2012. Consumption-weighted comparisons of... more

Introduction: The present study sought to identify time-dependent within-participant effects of CYP2A6 genotypes on smoking frequency and nicotine dependence in young smokers. Methods: Predicted nicotine metabolic rate based on CYP2A6 diplotypes (CYP2A6 Diplotype Predicted Rate [CDPR]) was partitioned into Normal, Intermediate, and Slow categories using a metabolism metric. Growth-curve models... more

Tob Control. 2015 Jul;24 Suppl 3:iii17-iii24.
Authors: Curti D, Shang C, Ridgeway W, Chaloupka FJ, Fong GT.

Background: Little research has been done to examine whether smokers switch to illegal or roll-your-own (RYO) cigarettes in response to a change in their relative price. Objective: This paper explores how relative prices between three cigarette forms (manufactured legal, manufactured illegal and RYO cigarettes) are associated with the choice of one form over another after controlling for covariates, including sociodemographic... more

The Society of Behavioral Medicine (SBM) urges policymakers to help prevent childhood obesity by improving state regulations for early care and education (ECE) settings related to child nutrition, physical activity, and screen time. More than three quarters of preschool-aged children in the USA attend ECE settings, and many spend up to 40 h per week under ECE care. ECE settings provide... more

Validation work of the Child Feeding Questionnaire (CFQ) in low-income minority samples suggests a need for further conceptual refinement of this instrument. Using confirmatory factor analysis, this study evaluated 5- and 6-factor models on a large sample of African-American and Hispanic mothers with preschool-age children (n=962). The 5-factor model included: 'perceived responsibility', 'concern about child's... more
