Trends and factors associated with long-acting reversible contraception in Kenya [version 1; peer review: 1 approved, 2 approved with reservations]

Background: Kenya has 12 million female adolescents and youths aged 10-34 years whose reproductive behavior will determine the growth and size of its population for the next decade. The anticipated momentum of births can be slowed by the use of long-acting reversible contraception (LARC) methods as they are more effective, need no user adherence, and hence have no risk of incorrect or inconsistent use. However, in spite of the many health and social benefits, LARC is underutilized because of myths and misconceptions. Kenya is in the ultimate decade towards Vision 2030 and investing in LARC can save costs of health care and accelerate the achievement of the development goal. The objective of this study was to establish factors associated with LARC use, with a view of establishing the potential for increasing demand. Methods: The study was national and used secondary data from the three waves of the Kenya Demographic Health Survey from 2003, 2008/09 and 2014 in a sample of all women of reproductive age who reported currently using modern contraceptive methods at the time of interview. Descriptive and logistic regression analysis was employed to profile and examine LARC users. Results: LARC use was low but picking up rapidly, especially among contraceptive users of higher social economic status in a major shift between 2008/09 and 2014. Consistent factors that influenced its use were age, wealth, and number of living children, while education and residence were of influence some of the time. Conclusions: There is huge unexploited potential for more LARC uptake based on the identified predictors of its use. Scaling up of LARC uptake is critical to deal with issues of poor user adherence, incorrect and inconsistent use, and method failure that characterize short-acting contraception, resulting in increased unintended pregnancies, incidences of unsafe abortions and maternal and infant mortality.
