Adolescent Smoking Habits in Osun State Nigeria with Self-Report and Biomarker Data

Osun State, Nigeria, is the geographic scope of this dataset. It contains survey and biomarker measurements from 616 in-school adolescents, comparing self-reported smoking to exhaled carbon monoxide levels. The data was collected by Funmito Omolola Fehintola using a cross-sectional study design and was last updated on 2026-04 28.

Use Cases

• Analyzing the discrepancy between self-reported and objectively measured smoking prevalence based on the study's findings.
• Modeling determinants of adolescent smoking behavior based on variables like age and class level mentioned in the description.
• Assessing the agreement between survey and biomarker data using metrics like Cohen's kappa reported in the study.

Strengths

• Includes objective biomarker measurements (exhaled carbon monoxide) for 616 participants, providing a validation layer.
• Reports specific prevalence figures: 13.0% by self-report and 27.3% by smokerlyzer.
• Data is openly licensed under CC-BY-4.0 for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to a specific region (Osun State, Nigeria) and population (in-school adolescents), which may affect generalizability.
