Food Choices and Hypertension Among Rural Thais: Evidence From a Discrete Choice Experiment

Area of Science:

• Public Health
• Nutritional Science
• Behavioral Economics

Background:

• The rural northern region of Thailand faces a high prevalence of hypertension.
• Understanding food choices is crucial for developing effective public health interventions.

Purpose of the Study:

• To investigate food choice attributes influencing normotensive and hypertensive individuals in rural northern Thailand.
• To identify key factors driving dietary decisions in a high-hypertension-prevalence area.

Main Methods:

• A discrete choice experiment (DCE) survey was administered to 403 Thai adults in rural northern Thailand.
• A mixed logit model analyzed the relative importance of food preparation, price, taste, and salt content.

Main Results:

• The amount of salt and home food preparation were the most significant attributes for both groups.
• Normotensive individuals showed greater sensitivity to the salt content in food compared to hypertensive individuals.
• Price and taste were less influential than salt and preparation methods.

Conclusions:

• Intervention programs should promote low-salt cultural foods and educate on flavor enhancement without added sodium.
• Strategies focusing on reducing high-sodium seasonings while maintaining taste are recommended.
• Public health initiatives can leverage cultural food practices for hypertension management.
