THE EFFECT OF COUPLES' MOTIVATIONAL INTERVIEW IN PREGNANCY ON MEN'S SMOKING AT HOME

Complications of exposure to second-hand smoke (SHS) are known to affect the health of pregnant women and fetus and it requires designing interventions to reduce the exposure of pregnant women to smoke. This study, therefore, aimed to examine the effect of couples' motivational interview in pregnancy on men's smoking at home.

The present study is a clinical trial study. 112 couples (56 non-smoking pregnant women with smoking spouses) enrolled in the study. Sampling was performed in several steps. First, according to the social, economic, and cultural conditions of the city, Urmia was divided into three sections, and two comprehensive health centers were randomly selected from each section. Blocked randomization method was used for random allocation in control and intervention groups. The motivational interview was conducted in 5 sessions of 60 minutes twice a week for intervention group. Individuals in both groups completed a demographic and smoking behavior questionnaire. The control group received routine prenatal care. Post-test was performed in the control and intervention groups 7 days and 30 days after the intervention. Data were analyzed by parametric and non-parametric tests and repeated measures in SPSS software version 20.

One hundred two couples completed the study. Mean smoking in the last week by the spouse, before, one week, and one month after the intervention were (70-172/5) 110, (40-135/5) 70, and (46-122/5)69.50 cigarettes, respectively. The results showed that these changes were statistically significant (p <0.001).

Couples' motivational interviews can be used to reduce smoking by the spouse, and ultimately this behavior change reduces the pregnant mother's exposure to secondhand smoke.
