The role of intrapersonal and interpersonal factors in waterpipe cessation: a case-control study

The prevalence of waterpipe smoking among women in southern Iran is significantly higher than women in other regions of Iran. We aimed to explore the effect of several demographic factors, knowledge, attitude, self-efficacy and social norms on a successful cessation of waterpipe smoking in the marginalized women of Bandar Abbas city, in the south of Iran.

This case-control study was conducted in 2022 among 731 women (246 subjects who successfully quit waterpipe smoking in the case group and 485 who smoked waterpipe in the control group). A cluster sampling method was used to collect the required data through face-to-face interviews and a researcher-made questionnaire. The questionnaire consisted of demographic information, behavioral information about waterpipe smoking and knowledge, attitude, self-efficacy and social norms. The data were analyzed in STATA 14 using univariate and multivariate regression analyses.

The mean and standard deviation of age was 39.24 ± 11.93 and 37.18 ± 13.57 in the control and case groups, respectively. With an increase of one score in social norm (OR: 1.046), the odds of cessation were increased for 4%. With an increase of one score in self-efficacy (OR: 1.152), the odds of cessation were increased for 15%. With an increase of one score in knowledge (OR: 1.064), the odds of cessation were increased for 6%. With an increase of one score in attitude (OR: 1.215) the odds of cessation were increased for 21%.

The present findings revealed personal and interpersonal influential factors in successful waterpipe cessation. Women's knowledge can be increased and their attitude can be changed. Important people in women's lives can be influenced to, consequently, affect women positively and improve their self-esteem.
