      OBJECTIVE To characterize age-group specific patterns in the stability of contraceptive use, and evaluate whether factors associated with non-use and sporadic use as compared to stable use differ by age among women at risk for unintended pregnancy. STUDY DESIGN We used data from the 2006–2010 National Survey of Family Growth to characterize the prevalence of stable and sporadic contraceptive use and non-use by age over a 1-year period. We used polytomous logistic regression models to assess the odds of contraceptive non-use and sporadic use versus stable use. Age-stratified models were used to show age-group differences in associated characteristics. RESULTS Over a 1-year period, stable contraceptive use decreased across age groups from 80% for teens 15–19 years to 74% for women 20–24 years, and 70–71% for women 25–34 and 35–44 years. Contraceptive non-use increased across age groups from 5% for teens 15–19 years to 9%–20% for older women. By contrast sporadic use was least common for women 35–44 years (10%, compared to 16–17% for younger women). Among teens 15–19 years, a history of method discontinuation due to dissatisfaction was associated with non-use. Among older women, intentions to have children in the future and reported difficulty achieving pregnancy were associated with non-use and sporadic use. CONCLUSION Because the stability of contraceptive use and associated factors differ by age, providers may need to consider these differences when talking to women about contraception. To address non-use, it may be especially important to help teens identify a method they are comfortable using, while for older women it may be more important to discuss the potential for continuing fertility. To address sporadic use, it may be helpful to discuss the benefits of user-independent methods, with a particular emphasis on long acting reversible contraceptives for younger women and teens who are less likely to have completed their desired childbearing and have tended to rely on methods that are more difficult to use consistently.
