Adolescent Obesity and Dental Caries in Southern Brazil, 5-Year Cohort

Southern Brazilian adolescents were examined in 2018 and reassessed after 5 years to study the influence of obesity on dental caries increment. The dataset includes baseline sociodemographic, behavioral, anthropometric, and oral health data for 1,197 participants, with 570 followed up. It was published on figshare under a CC-BY-4.0 license by an administrator for Karger.

Use Cases

• Analyze the association between adolescent weight status and caries increment based on the Decayed, Missing or Filled Surfaces (DMFS) index.
• Model caries risk factors based on sociodemographic and behavioral variables like family income and toothbrushing frequency.
• Study longitudinal oral health changes in a young adult population based on the 5-year follow-up data.

Strengths

• Prospective cohort design with a 5-year follow-up period.
• Baseline data includes 1,197 participants with sociodemographic, behavioral, anthropometric, and clinical oral health measurements.
• Analysis includes specific statistical results, such as a caries increment of 1.79 surfaces and an incidence risk ratio of 2.32 for obese participants.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Retention rate was 47.6%, which may introduce attrition bias.
