• Effectiveness of a Vaping Cessation Text Message Program Among Young Adult e-Cigarette Users

  JAMA Internal Medicine · 2021 · 171 citations

  Senior authorCorresponding

  Importance: e-Cigarettes are the most commonly used tobacco product among young adults (YAs). Despite the harms of nicotine exposure among YAs, there are few, if any, empirically tested vaping cessation interventions available. Objective: To determine the effectiveness of a text message program for vaping cessation among YAs vs assessment-only control. Design, Setting, and Participants: A parallel, 2-group, double-blind, individually randomized clinical trial was conducted from December 2019 to…

  Importance: E-cigarettes are the most commonly used tobacco product among adolescents. Despite known harms of nicotine exposure among teens, there are no empirically tested vaping cessation interventions. Objective: To compare the effectiveness of a text message program for nicotine vaping cessation among adolescents with assessment-only control. Design, Setting, and Participants: A parallel, 2-group, double-blind, individually randomized clinical trial with follow-ups at 1 and 7 months after ra…

• A multi-component tailored intervention in family childcare homes improves diet quality and sedentary behavior of preschool children compared to an attention control: results from the Healthy Start-Comienzos Sanos cluster randomized trial

  International Journal of Behavioral Nutrition and Physical Activity · 2022 · 29 citations

  BACKGROUND: Childcare settings are important environments for influencing child eating and physical activity (PA). Family childcare homes (FCCH) care for many children of low-income and diverse racial/ethnic backgrounds who are at greater risk for poor diet quality, low PA, and obesity, but few interventions have targeted this setting. The aim of this study was to assess the efficacy of a multicomponent intervention conducted in FCCH on the diet quality and PA of 2-5 year old children in their c…

• Evaluation of Naturalistic Driving Behavior Using In-Vehicle Monitoring Technology in Preclinical and Early Alzheimer’s Disease

  Frontiers in Psychology · 2020 · 29 citations

  Cognitive impairment is a significant risk factor for hazardous driving among older drivers with Alzheimer's dementia, but little is known about how the driving behavior of mildly symptomatic compares with those in the preclinical, asymptomatic phase of Alzheimer's disease (AD). This study utilized two in-car technologies to characterize driving behavior in symptomatic and preclinical AD. The goals of this pilot study were to (1) describe unsafe driving behaviors in individuals with symptomatic…
