Number of observations is based on outcomes over 60 months from January 2011 to December 2015. Volume (mL) of items purchased per capita per month. For sugar, the unit of measurement is g per 100 mL. 3. SES is that given by Kantar WorldPanel. Occupation, education, and age refer to the household head. Mean adult BMI is calculated for all household members older than 18 years. If a household did not participate in 2014, we prioritised the use of subsequent years (2015, 2013, 2012, 2011). The number of products is based on SKU; i.e., items with different barcodes (for example, items with the same ingredients but with different package sizes) are treated as distinct SKUs.
Abbreviations: BMI, body mass index; SES, socioeconomic status; SKU, stock-keeping unit.
