Acute sadness was associated with reduced, rather than increased, UPF intake in the laboratory, while naturalistic affect did not predict UPF intake.
Study context
- Population
- Youth with overweight or obesity: Study 1, girls aged 7–12 years; Study 2, youth aged 8–14 years46 girls (Study 1)
- Comparison
- Negative vs neutral mood induction (Study 1); affect ratings and %UPF intake over time (Study 2)
- Outcome
- Percentage of energy from UPFs (%UPF), foods classified using NOVA
Methodological detailscounterbalanced mood inductions, 14-day ecological momentary assessment (EMA) protocol, lagged multilevel models
- Counterbalanced mood inductions
- 14-day EMA protocol

As reported in the abstract
Further findings
Post-induction sadness and subsequent %UPF intake, within negative mood condition (Study 1)
- Greater post-induction sadness predicted lower subsequent %UPF intake (b)
- −0.076, p = 0.015
Affect and %UPF intake in daily life (Study 2)
- Affect did not prospectively predict subsequent %UPF intake, and %UPF intake did not predict subsequent affect
- all p > 0.20
