The aim of this work is to evaluate the effects of two soft drink policies (soft drink taxes and restricting vending machine access in schools) on child and adolescent soft drink consumption and body weight. Investigators will use a ‘natural experiment’ design by leveraging state and time variation in these soft drink policies combined with three large, nationally representative datasets that contain information on state of residence, soft drink consumption, body mass index (BMI), and a rich set of socio-demographic variables. These econometric analyses will focus specifically on influences among at-risk populations, including individuals in low income communities and racial/ethnic minorities.

Taxing Soft Drinks and Restricting Access to Vending Machines to Curb Child Obesity

This paper focused on the impact changes in soft drink taxes and policies restricting school vending machine access had on soda consumption among children and adolescents. The researchers used data from the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) and IV (1999-2006) and the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K).

Can Soft Drink Taxes Reduce Population Weight?

This paper evaluates the impact of changes in state soft drink taxes on body mass index (BMI), obesity and overweight. Researchers found that weight responds to changes in soft drink taxes; an increase of 1% in the state soft drink tax rate leads to a decrease in BMI of 0.003 points and the influence of More

The Effects of Soft Drink Taxes on Child and Adolescent Consumption and Weight Outcomes

In this paper the authors investigate the potential for soft drink taxes to combat the rise in child and adolescent obesity levels through a reduction in consumption. Using state soft drink sales and excise tax information from 1989-2006 and National Health Examination and Nutrition Survey (NHANES) data, researchers find that currently practiced soft drink taxation More
