    This study on smoking patterns in London workplaces found significant differences in smoking rates and timing based on occupation and smoking restrictions. Office workers had more non-smokers, while those with fewer restrictions smoked more, with peak times varying by group.

    Area of Science:

    • Occupational Health
    • Behavioral Science
    • Public Health

    Background:

    • Smoking prevalence and patterns vary significantly across different occupational settings.
    • Workplace smoking restrictions can influence non-smoker proportions and overall cigarette consumption.
    • Understanding daily smoking rhythms is crucial for targeted health interventions.

    Purpose of the Study:

    • To investigate and compare daily cigarette smoking rates across three distinct occupational groups in London.
    • To identify how workplace smoking policies affect smoking behavior and consumption.
    • To determine optimal timing for biological sample collection for smoking-related biomarkers.

    Main Methods:

    • Survey data collected from 3174 participants across a food processing factory (production and administrative) and a local borough office.

  • Categorization into three groups based on work environment and smoking restrictions.
  • Analysis of self-reported smoking rates during different periods of the day.

    • Main Results:

    • Non-smoker proportions were higher in office environments (over 70%) compared to factory production (about 55%).
    • Workers in Group 3 (no restrictions) exhibited higher average cigarette consumption.
    • Peak smoking rates varied: Groups 1 & 2 peaked post-work, while Group 3 peaked during afternoon work hours.

    Conclusions:

    • Occupational setting and smoking restrictions significantly impact smoking prevalence and daily patterns.
    • Distinct smoking times observed between restricted and unrestricted environments.
    • Findings inform the timing of carboxyhaemoglobin estimations for accurate smoking status assessment.
