Sugar-sweetened beverage consumption in Thailand: Determinants and variation across socioeconomic status

Objectives: Reducing consumption of sugar-sweetened beverages (SSBs) is a primary public health goal in Thailand, but information on the characteristics of SSB consumers remains limited. This study aims to gain knowledge about the characteristics of SSB consumers in Thailand. Study design: Secondary analysis of survey data. Methods: The study used data from the Health Behaviour of Population Survey conducted by Thailand's National Statistics Office between February and May 2021. SSB consumption was sourced from a survey question about the consumption of prepackaged sugar-sweetened non-alcoholic beverages. The influence of demographic, socioeconomic, behavioural, habitual, and health factors on mean daily intake and daily consumption was assessed using a two-part model and logistic regression analysis, respectively. Decomposition analysis was conducted to understand how the impact of these factors affecting SSB consumption varied across socioeconomic groups. Results: Frequent SSB consumers exhibited various unhealthy behaviours, including smoking, unhealthy food consumption, low physical activity, and making food selections driven by appetitive motivations. Although higher socioeconomic status was associated with greater consumption of SSBs, it stabilised at elevated income levels. Increased SSB consumption in higher socioeconomic groups was linked to mixed eating habits, being overweight, and occasional drinking, while in lower socioeconomic groups, it was associated with unhealthy behaviours like smoking, regular alcohol drinking, appetitive food choices, and low physical activity. Conclusions: SSB consumption in Thailand is multifactorial, varying by socioeconomic status. These insights are crucial for policy formation aimed at reducing SSB consumption in the country. Policymakers should explore interventions that address overall unhealthy behaviours alongside those targeting overconsumption of SSBs.
