Background:Women in Baltimore City, Maryland have been able to order home collection kits via internet recruitment, iwantthekit.org since 2004.
Objectives:To compare the socio-demographic characteristics of census block groups (CBGs) where women have utilized iwantthekit for STI testing to those of CBGs where women have not.
Methods:Addresses were collected for each kit request between 2004 -2009, and were geocoded into 710 CBGs. CBGs from which kits were ordered (kit requesting CBGs) were compared to CBGs who did not order kits (non-kit requesting CBGs).The population characteristics of the two groups were compared using Chi Square. The means of percent home ownership and percent below poverty among CBGs were analyzed using t-test.
Results:From 2004 to 2009, there were 545 kit requesting CBGs, 159 non-kit requesting CBGs and 6 CBGs without any population. Kit requesting CBGs had a higher mean for percent of population below poverty (24.7% v. 20.1%) and a lower mean for percent of home-ownership (51.3% v. 58.9%),(p<0.01). 70.1% of kit requesting CBGs had a higher proportion of black female population (out of the total female population) when compared to 39.6% of non-kit requesting CBGs,(p<0.001). Furthermore, 58.4% of kit requesting CBGs had chlamydia rates above the Baltimore City morbidity rate for 2006 (989.1 per 100,000) compared to 48.4% of non-kit requesting CBGs (p<0.05). However, differences in gonorrhea rates between the two CBG categories were not significant.
Conclusions:Kit requesting CBGs were more likely to have a population below poverty, and have lower rates of home ownership. Kit requesting CBGs also had a higher percent of black female population and had higher chlamydia rates.
Implications for Programs, Policy, and Research:STD programs may be able to utilize the Internet testing data to identify and target services for high morbidity populations. Internet testing may be a valuable tool for chlamydia testing in high morbidity areas.
