The objective of the study was to determine the spatial variation in modern contraceptive use and unmet need for family planning
across the counties of Kenya and to examine whether the spatial patterns were associated with inequalities in physical access to
health facilities. Data were obtained from the 2008-2009 Kenya Demographic and Health Survey and linked to the location of
health facilities in the country. Multivariate logistic regression was used to examine the influence of distance to the nearest health
facility and health facility density, in addition to other covariates, on modern contraceptive use and unmet need. Overall, the
prevalence of modern contraceptive use and unmet need among women aged 15-49 in Kenya was 42.1% and 19.7% respectively.
Among the respondents who lived more than 5 km from the nearest health facility modern contraceptive use was significantly
less likely compared to women resident 5 km or less from the nearest health facility. Women from counties with higher health
facility density were 53% more likely to use modern contraceptives compared to women in counties with low health facility
density. Distance and health facility density in the county were not significantly associated with unmet need. Physical access to
health facilities is an important determinant of modern contraceptive use and unmet need in Kenya. Strategies should be
developed in underserved counties to mitigate the challenge of distance to health facilities, such as delivering services by
outreach and mobile facilities.
