Acne and Dietary Patterns in Shanghai Adolescents, 2025 Cross-Sectional Study

A 2025 cross-sectional study of 1,299 junior high school students (aged 11–16 years) in Shanghai, China, investigating the association between high-sugar and high-fat dietary patterns and acne vulgaris. The dataset was created by Ruiqi Cai and published on figshare in 2026. It includes a constructed Dietary Exposure Index (DEI) and results from questionnaires and clinical skin examinations.

Use Cases

• Analyze the dose-response relationship between a cumulative dietary index (DEI) and acne prevalence.
• Model the association between specific beverage consumption (sugar-sweetened drinks, milk tea, coffee) and acne risk.
• Investigate demographic factors like grade level and age in relation to acne prevalence in adolescents.

Strengths

• Includes data from 1,299 participants, providing a substantial sample size.
• Uses a constructed Dietary Exposure Index (DEI, range 0-5) to quantify cumulative dietary patterns.
• Data collection combined questionnaires with onsite clinical skin examinations for outcome assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The cross-sectional design limits causal inference.
