Background: The combined oral contraceptives (COCs) and intrauterine devices (IUDs) are the most common contraceptive methods used by women. Women's choices of contraceptive method are largely affected by the safety and efficacy of contraceptive methods as well as by change in women's quality of life. However, there are still scanty data focusing on the impact of COC or IUD on quality of life in women, especially in China. The aim of this study was to evaluate the impact of desogestrel and ethinyl estradiol tablets (Marvelon) and Yuangong-Cu220 IUD (YCu220 IUD) on quality of life in rural women of the Jiangsu province in China. Study Design: In this prospective cohort study, 784 COC users and 910 YCu220 IUD users were included. The women filled up quality-of-life questionnaires (Quality of Life Enjoyment and Satisfaction Questionnaire) before and after use of contraceptive methods. Results: Significant score changes in physical health, mood, work/school/labor, living situation, vision, general well-being and overall satisfaction were noted as significant improvements after COC use in women (p<.05), and the largest improvements were in physical health and living situation; all item scores except for work/school/labor, household activities and leisure time activities had improved statistically from baseline in YCu220 IUD users (p<.05). For COC users, the proportions of women with total quality-of-life scores ≥57 before and after COC use were 11.50% and 11.79%, respectively; but the proportion of YCu220 IUD users with total quality-of-life scores ≥57 increased from 4.40% to 12.04%. Compared to women without contraceptive use history, women with past OC and/or IUD use had a significantly higher difference in the total quality-of-life scores. Conclusions: COC and YCu220 IUD could significantly improve overall quality of life in rural women of the Jiangsu province. © 2009.
