Prevalence and correlates of nicotine dependence among construction site workers: A cross-sectional study in Delhi.
BACKGROUND
Workers represent half the world's population and are major contributors to economic and social development. Tobacco consumption in construction site workers has been considered a big challenge.


OBJECTIVE
(1) To assess the prevalence of nicotine dependence among tobacco users. (2) To study the correlates of nicotine dependence among the construction site workers.


METHODS
A cross sectional study was conducted using a predesigned and pretested structured proforma. The study was conducted among all construction site workers aged 18yrs and above in campus of Hamdard Institute of Medical Sciences and Research and associated HAH centenary hospital, New Delhi. Karl Fagerstrom Nicotine Dependence Questionnaire was used to assess dependence on nicotine.


RESULTS
The mean age of construction site workers was 32.04±11.6 years. Among the workers, majority (91%) were tobacco user. Among the users, 60% found it difficult to refrain from smoking/chewing in places where use of tobacco is not allowed (e.g. hospitals, government offices, cinemas, Libraries etc). 55% of the users smoked or chewed tobacco during the first hours after waking than during the rest of the day. On multivariate analysis, the factors which were found to be significantly associated with nicotine dependence were lower income group (OR 2.57, CI:1.66-3.99), smokeless tobacco use (OR 2.36, CI:1.30-4.27) and lower education (OR = 2.86 (95% CI 1.97-4.16) for illiterate).


CONCLUSIONS
The prevalence of tobacco use (91%) among construction workers is very high compared to that in the general population. Recognition of construction sites as work places and proper implementation of law is needed.
