Associations of the Philadelphia sweetened beverage tax with changes in adult body weight: an interrupted time series analysis.

ABSTRACT:

Background

Sweetened beverage taxes are associated with large decreases in sugar-sweetened beverage sales, but their effects on weight outcomes are unclear. We examined associations of the 2017 Philadelphia beverage tax with changes in adult weight outcomes.

Methods

A panel sample comprised 175,675 adults with at least one BMI measure in both the pre-tax (2014-2016) and post-tax (2017-2019) periods. A cross-sectional sample comprised 587,121
