Relationship between Unwanted Pregnancy and Health-Related Quality of Life in Pregnant Women.

OBJECTIVE To determine the relationship between unwanted pregnancy and health-related quality of life in pregnant women. STUDY DESIGN Case-control study. PLACE AND DURATION OF STUDY Department of Community Medicine, Kermanshah University of Medical Sciences, Kermanshah, Iran, from October 2013 to July 2014. METHODOLOGY Of the pregnant women who presented to primary healthcare centers of Kermanshah, Iran to receive prenatal care at 6 - 10 weeks of their pregnancy, those with unwanted pregnancy were selected as cases and those with wanted pregnancy were selected as control group. The selection process was done using multi-stage stratified random sampling. Frequency matching was applied to match the two groups. Quality of life was measured by the SF-36 questionnaire and was compared by the t-test. Relationship power between pregnancy type (wanted or unwanted pregnancy) and impairment of quality of life subscales as the outcome was assessed using odds ratio (OR). RESULTS Frequency distribution of matched variables was not statistically different between the two studied groups. Mean scores of mental component summary and physical component summary as well as eight subscales (physical functioning, role, bodily pain, general health, vitality, social functioning, role emotional, and mental health) were lower in the unwanted pregnancy group compared to women with wanted pregnancy (p < 0.001). The highest high impairment odds ratio was highest for the mental component summary (MCS) (OR = 9.19; 95% CI = 5.17- 16.32) and vitality subscale (OR = 5.2; 95% CI = 2.89- 9.33). CONCLUSION Mental health of the pregnant women with unwanted pregnancy is affected more than their physical health. Mental health in women with unwanted pregnancy is 9.19 times more likely to be reduced. Among mental health subscales, vitality (energy/fatigue) showed the highest decrease.
