Changes in concentrations of tobacco specific nitrosamines in saliva in the general popula

272 adults in Barcelona were surveyed longitudinally in 2004–2005 and 2013–2014 to evaluate changes in salivary tobacco-specific nitrosamines (TSNAs) before and after Spain's 2006 smoke-free law. Among baseline smokers who quit, TSNA concentrations decreased by up to −90.5%, while continuing smokers showed a 149.8% increase in NNN. The dataset, authored by Hipólito Pérez-Martín and shared under CC-BY-4.0, contains geometric means and confidence intervals for NNN, NNK, and NNAL, stratified by sociodemographics and smoking status.

Use Cases

• Modeling the longitudinal impact of smoke-free legislation on biomarker levels based on pre- and post-law measurements.
• Analyzing differences in tobacco-specific nitrosamine concentrations based on smoking behavior and cessation status.
• Studying potential compensatory smoking behaviors among continuing smokers after policy implementation based on TSNA concentration changes.

Strengths

• Longitudinal design with two survey waves spanning a major policy intervention (2006 legislation).
• Specific biomarker results are provided, including geometric means and 95% confidence intervals for three TSNAs.
• Data is stratified by multiple factors including sociodemographics, smoking status, and anthropometrics.

Limitations

• The dataset is small in scale at 622.4 KB, with an unknown row count.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is geographically limited to the general population of Barcelona, Spain.
