Second Hand Smoke Exposure among Pregnant Women in Nigeria

ABSTRACT

Background:Despite the ban on smoking in public places in Nigeria, second-hand smoke exposure is common across the country. It is increasingly being viewed as a severe women’s issue because of the high prevalence among women, and its harmful effects on pregnant women. However, second-hand smoke exposure among pregnant women in Nigeria is hugely under-researched.Aim:This study aims to determine the prevalence of second-hand smoke exposure among pregnant women in Nigeria, and determine their knowledge and avoidance behavior towards second-hand smoke. Methodology: This cross-sectional study was conducted among 314 pregnant women in ten health facilities in Sokoto state, Nigeria. The health facilities were selected through simple random sampling.Results: The prevalence of second-hand smoke exposure was 72.9%. The majority of the respondents (61.1%) were exposed to second-hand smoke in homes of others, 20.4% in school 18.5% in restaurants, 43.3% in their own homes, 49.7% in public transport, 20.4% at work, and 15% in health facilities. Factors significantly associated with second-hand smoke exposure included knowing it causes miscarriage (OR=0.39, 95% CI=0.23 –0.64, P= <.001), and being able to keep a distance from smokers (OR=0.5, 95% CI= 0.28 –0.76, P=.002).Conclusion:This study revealed a high prevalence of exposure to second-hand smoke. Knowledge about the harmful effects of second-hand smoke was one of the significant factors associated with exposure. These findings indicate the need for appropriate education ofall pregnant women about the harmful effects of second-hand smoke and adequate enforcement of the ban on smoking in public places
