Abstract

Objectives The objective of this study was to compare the patterns of smoked and smokeless tobacco use among multimorbid and non-multimorbid middle-aged and older-aged individuals in Karachi, Pakistan.Study design This was an observational cross-sectional study conducted during 2015–2016.Study setting and participants A total of 3250 participants aged 30 years and above, residing in the Gulshan-e-Iqbal town, Karachi, Pakistan were enrolled in the study through systematic random sampling. The selected area of residence represents diverse socioeconomic and ethnic groups of the city. People who could speak and write English or Urdu, and those who provided written informed consent were included in the study.Outcome measures The primary outcome measure of the study was to determine the differences in patterns of tobacco consumption among multimorbid and non-multimorbid adult individuals.Results We found no difference in patterns of smoked (adjusted OR (aOR) 1.15, 95% CI 0.88 to 1.50, p=0.289) or smokeless tobacco (aOR 1.13, 95% CI 0.86 to 1.48, p= 0.379) use among multimorbid and non-multimorbid individuals. Individuals who perceived tobacco as a risk were less likely to consume smokeless tobacco products.Conclusion There was no difference in tobacco consumption among individuals with and without multimorbidity. Evidenced-based guidelines are required to implement mental and behavioural interventions in patients with multiple chronic diseases to help them modify their behaviours.
