Longitudinal cohort study reveals narrowing income gradients in animal-source food intake among Chinese adults, indicating widespread diet Westernization across socioeconomic levels.

Key Points

To examine whether the relationship between urbanization and animal-source food consumption varies by income and how this dynamic changes over a 24-year period.
Analyzed data from nine waves of the longitudinal China Health and Nutrition Survey (1991–2015) comprising N=22,360 Chinese adults followed across 24 years.
Assessed dietary intake via three repeated 24-hour dietary recalls per wave.
Implemented simultaneous year-stratified linear regression models adjusting for age, sex, region, physical activity, and total energy intake while accounting for within-individual correlation.
Average daily calories derived from animal-source foods increased from 15% in 1991 to approximately 25% by 2015.
Urbanization and income were strongly associated with animal-source caloric intake, displaying significant variation across income groups (p < 0.0001) and over time (p < 0.0001).
Income gradients in animal-source food intake narrowed over time in low- and moderately urbanized communities, resulting in minimal income-based consumption differences across urbanization tiers by 2015.
