^aValues are 1s mean ± S.E. and adjusted for energy intake, BMI, physical activity score, sex, age, education, income to poverty ratio, and diabetes. For sweets, analyses were stratified by diabetes due to a stress × diabetes interaction. ns, not statistically significant (P > 0.05).

^*Indicates a statistical difference (P ≤ 0.05) from the lowest quartile within the same row.

^#Indicates a tendency (P ≤ 0.01) to be statistically different.
