<p>Sociodemographic characteristics of respondents.</p>

616 in-school adolescents from Osun State, Nigeria, were surveyed for smoking status using both a Smokerlyzer device and a WHO STEPwise questionnaire. The dataset, created by Funmito Omolola Fehintola and last updated in April 2026, contains sociodemographic characteristics and smoking behavior data. It reveals a discrepancy, with 13.0% self-reporting smoking and 27.3% detected as current smokers by the objective measure.

Use Cases

• Analyzing the discrepancy between self-reported and objectively measured smoking prevalence.
• Identifying sociodemographic predictors of adolescent smoking based on age and class level.
• Training models to assess risk factors for non-communicable diseases among youth.
• Evaluating the effectiveness of different data collection methods for health surveillance.

Strengths

• Includes objective biometric measurement (exhaled carbon monoxide) alongside self-reported survey data.
• Dataset size is precisely defined with 616 respondents.
• Analysis includes specific statistical results, such as Cohen's κ of 0.063 and adjusted odds ratios for predictors.

Limitations

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