TOPLINE:
A higher intake of ultraprocessed foods increases the risk for systemic lupus erythematosus (SLE) by over 50% in women. The risk doubled in those with anti–double-stranded DNA antibodies.
METHODOLOGY:
- Researchers assessed 204,175 women from two Nurses’ Health Study cohorts from 1984 to 2016.
- Participants completed semiquantitative food frequency questionnaires every 4 years for the assessment of dietary intake.
- Incident SLE cases were self-reported and confirmed using medical records, with 212 cases identified.
TAKEAWAY:
- A higher cumulative average daily intake of ultraprocessed foods was associated with a 56% increased risk for SLE (95% confidence interval [CI], 1.04-2.32).
- The risk for anti–double-stranded DNA antibody-positive SLE was more than doubled (hazard ratio, 2.05; 95% CI, 1.15-3.65).
- Sugar or artificially sweetened beverages were associated with a 45% increased risk for SLE (95% CI, 1.01-2.09).
- No significant interactions with body mass index were observed in the association between ultraprocessed food intake and SLE.
IN PRACTICE:
This study is too preliminary to have practical application.
SOURCE:
The study was led by Sinara Rossato, PhD, Harvard T.H. Chan School of Public Health, Boston. It was published online in Arthritis Care & Research.
LIMITATIONS:
The study’s generalizability is limited due to the predominantly White female population of registered nurses. The relatively high baseline age of participants may not fully capture the peak incidence age range for SLE. The observational nature of the study cannot establish causality between ultraprocessed food intake and SLE risk.
DISCLOSURES:
The study was supported by the National Institutes of Health. The authors did not declare any competing interests.
