Dietary Inflammatory Index and Depressive Symptoms in Elderly Hong Kong Chinese

Agassi Chun Wai Wong published a longitudinal cohort study on figshare. The dataset contains results from a 7-year study of 3,740 elderly Chinese subjects in Hong Kong, analyzing the association between Dietary Inflammatory Index (DII) scores and Geriatric Depression Scale (GDS) outcomes. The study found a significant positive association, particularly among females.

Use Cases

• Analyze longitudinal associations between diet and mental health based on Dietary Inflammatory Index scores.
• Investigate sex differences in diet-depression relationships based on the study's findings.
• Benchmark dietary inflammation models in non-Western populations based on the Hong Kong cohort.
• Study attrition bias correction methods based on the use of inverse probability weighting.

Strengths

• Longitudinal design with 7 years of follow-up.
• Substantial cohort size of 3,740 elderly subjects.
• Uses validated instruments: Geriatric Depression Scale and Food Frequency Questionnaire.

Limitations

• Single dietary assessment at baseline may not capture dietary changes over time.
• Substantial attrition was noted, requiring statistical correction.
• Column-level documentation is absent; field semantics must be inferred after download.
