Correlates of Dual-Method Contraceptive Use: An Analysis of the National Survey of Family Growth (2006–2008)

OBJECTIVE To analyze a nationally representative sample of women for correlates of dual-contraceptive-method use. MATERIALS AND METHODS We conducted an analysis of the National Survey of Family Growth, 2006-2008, a cross-sectional survey of reproductive-aged women in the United States. RESULTS Dual method use was reported by 7.3% of the 5,178 women in the sample. Correlates of higher rates of dual-contraceptive-method use included age younger than 36 years and nonmarried marital status. Lower rates of dual method use were observed for women with less than a high-school education and women without consistent health insurance in the past year. Compared to women using oral contraceptives, use of the contraceptive injection or long-acting reversible contraception was associated with lower dual-method use. CONCLUSIONS The overall rate of dual-method use in the USA is low. Future interventions to promote dual method use should target high-risk groups with modifiable risk factors.
