Abstract
The New York City (NYC) Department of Health and Mental Hygiene released the Teens in NYC mobile phone application (app) in 2013 as part of a program to promote sexual and reproductive health among adolescents aged 12-19 in NYC. The app featured a locator that allowed users to search for health service providers by sexual health services, contraceptive methods, and geographic locations. We analyzed data on searches from the Where to Go section of the app to understand the patterns of use of the app’s search functionality. From January 7, 2013, through March 20, 2016, the app was downloaded more than 20 000 times, and more than 25 000 unique searches were conducted within the app. Results suggest that the app helped adolescents discover and access a wide range of sexual health services, including less commonly used contraceptives. Those designing similar apps should consider incorporating search functionality by sexual health service (including abortion), contraceptive method, and user location.

In the United States, rates of pregnancy, 1 –3 sexually transmitted infections (STIs), 4,5 and human immunodeficiency virus (HIV) infection 6,7 are higher among adolescents than among other age groups. Although traditional media (eg, television, film, radio, and music) 8 have featured campaigns to promote adolescent sexual health, new media (eg, mobile phones, mobile applications [apps], and social networking sites) have not yet been effectively used for this purpose. 8,9 Many adolescents feel that sexual health information is important 10 and are receptive to using mobile technology (including mobile phones) to access it. 10 –19
Mobile phones are a promising technology for engaging adolescents in accessing information about sexual health topics. Mobile phone ownership is common in the United States, particularly among adolescents. In 2015, 73% of teenagers aged 13-17 owned a mobile phone, of whom 91% used their mobile phone to access the internet. 20 The use of mobile technology for health promotion offers privacy, 9,10,13,14,21 –23 access to personalized information, 8 –10,14,24 and convenience, 18,21,22 making it a valuable way to provide accurate information about sexual health to adolescents. 15,17,18,24 –26
In collaboration with the Bronx Teens Connection Youth Advisory Board, the New York City (NYC) Department of Health and Mental Hygiene (DOHMH) created the Teens in NYC mobile phone app in 2013. This app was an extension of a paper-based resource, launched in 2007, that listed health care providers in NYC that met best practices in sexual health care for adolescents. 27 The app had 3 main sections: Where to Go, What to Get, and What to Expect (Figure A). 28

Graphic user interfaces of Teens in NYC mobile application (app) (A) home page and (B) Where to Go section, used in 28 503 separate searches, New York City, February 27, 2013, through March 20, 2016. The home page is where users navigate to 1 of 3 main sections of the app: Where to Go (where to access sexual health services), What to Get (descriptions of contraceptive methods), and What to Expect (videos of adolescents accessing sexual health services). In the Where to Go section, users search for health care provider listings by selecting sexual health services (eg, birth control or gynecology) or contraceptive methods (eg, condoms) and by indicating their geographic location of interest (eg, current location).
The Where to Go section of the Teens in NYC app allowed users to find providers of sexual health services or contraceptive methods. Users were prompted to select from 3 menus (services, methods, and geography) on the same screen. Users could specify services or methods (each via drop-down menus) and indicate their geographic location of interest (using a particular address and/or borough or a current location) (Figure B). On each drop-down menu for services and methods, they could choose 0, 1, or >1. However, they had to make at least 1 selection in either the services menu or the methods menu. On the services drop-down menu, users could select “gold star” service to find providers who offered certain sexual health care services and contraceptive methods on-site for free.
The Where to Go section therefore allowed for the tailoring of information to the user’s needs and preferences, an approach that others have reported to be a key to the success of new media initiatives, 8 –10,14,24 including initiatives focused on contraceptive services. 29,30 The other 2 sections of the app supported the search functionality. The What to Get section provided brief descriptions of each contraceptive method, and the What to Expect section featured videos 29 of adolescents accessing sexual health services. We analyzed search data from the Where to Go section of the Teens in NYC mobile app to understand patterns of use of a mobile phone app that contained a provider locator for local sexual health care services.
Methods
We obtained a data set in Microsoft Excel from the NYC DOHMH information technology department that included all searches conducted using the app from February 27, 2013, through March 20, 2016 (NYC DOHMH, unpublished data). This data set consisted of a separate row for each search conducted and individual columns for the following variables of interest that users could select during a search: geographic location (current location, borough, or address), corresponding borough (when current location or address was searched), various sexual health services (birth control or gynecological service, STI testing and treatment, pregnancy testing, abortion service, HIV testing, gold star service, mental health counseling, and lesbian/gay/bisexual/transgender/queer [LGBTQ]–specific service), and various contraceptive methods (condom, oral contraceptive pill, emergency contraception, injectable contraception, female condom, hormonal intrauterine device, copper intrauterine device, contraceptive implant, vaginal ring, and contraceptive patch). We calculated percentages for variables with discrete outcomes (eg, frequency of selecting a particular service) and means and medians for variables with continuous outcomes (eg, number of services selected).
The information technology department also provided us with access to data on the number of apps that were downloaded from App Annie’s free online app monitoring tool, 30 as well as Apple’s iTunes Connect internet-based tool. 31 We obtained data on the number of downloads from the dates of the app’s launch (January 7, 2013, for Apple and January 14, 2013, for Android) through March 20, 2016, and we exported that data set (unpublished data) to Microsoft Excel.
Because both our search and download data sets included no personally identifiable user information, we were unable to link those data sets to determine how many users conducted searches. Instead, we used the number of app downloads to estimate the number of potential users of the app’s Where to Go section.
By accepting the Terms of Service for the Teens in NYC mobile app, users consented to anonymous data collection. NYC DOHMH privacy restrictions for adolescent-focused services prohibited the use of any existing analytics packages that would store data on users offsite or collect unique user information. For each Where to Go search performed, the app sent deidentified search information directly to a secure database at NYC DOHMH. No data were stored on users’ phones. The NYC DOHMH Institutional Review Board determined that this study did not meet the definition of research and was deemed exempt.
We compared the distribution of searches by corresponding borough of current location with the overall distribution of residents aged 12-19 by NYC borough by using data from the 2010 US Census. 32 We also compared the contraceptive methods searched with 2015 data from a representative sample of NYC public high school students in the Youth Risk Behavior Survey (YRBS). 33 The 2015 YRBS data describes contraceptive methods used at last sex among students who had sex in the past 3 months.
Results
We identified 22 137 downloads of the Teens in NYC mobile app from January 7, 2013, through March 20, 2016, and 28 503 unique searches in the app’s Where to Go section from February 27, 2013, through March 20, 2016. The geographic location of interest for searches was the user’s current location in 17 544 (65%) searches, a borough in 2885 (10%) searches, and an address in 1330 (5%) searches. Geographic selection data were missing in 5744 (21%) searches. Current locations used in searches came from all 5 NYC boroughs and were nearly proportional to the distribution of residents aged 12-19 across the boroughs (Table 1).

bLocation refers to the borough in which the user was when he or she performed the search. User could choose among 3 options for location of interest: current location (18 544 [65%] searches), borough (2885 [10%]) searches, and address (1330 [5%]) searches. Geographic selection data were missing in 5744 (20%) searches. “Current location” was default option.
cBased on data from US Census 2010. 32 Numbers were weighted for sample nonresponse.
Among all 28 503 searches of the Where to Go section of the Teens in NYC mobile app, 10 656 (37%) were for both 1 or more sexual health service and 1 or more contraceptive method, 10 134 (36%) were for only 1 or more sexual health service, and 5931 (21%) were for only 1 or more contraceptive method. Data on sexual health service and contraceptive method selections were missing in 1782 (6%) searches. Among all searches, 20 790 (73%) involved the selection of at least 1 sexual health service. A mean of 2 and median of 1 unique sexual health services were searched. A sexual health service was selected in searches 45 110 times. Of these, birth control or gynecological services were searched 12 509 (28%) times, STI testing and treatment 8902 (20%) times, pregnancy testing 7674 (17%) times, abortion services 7494 (17%) times, HIV testing 3874 (9%) times, gold star services 2201 (5%) times, mental health counseling 1607 (4%) times, and LGBTQ-specific services 849 (2%) times.
Among all 28 503 searches, 16 587 (58%) involved the selection of at least 1 contraceptive method. Of note, 2414 (8%) searches included the selection of condom or female condom with another contraceptive method. A mean of 2 and a median of 1 unique contraceptive methods were searched. Contraceptive method was selected in searches 26 539 times. Of these, condom was searched 6630 (25%) times. The most frequently searched methods (condom and oral contraceptive pill) were also the most commonly used methods in the 2015 YRBS. However, whereas 52% of the contraceptive methods searched were for other methods, only 19% of students in the 2015 YRBS reported using other methods (Table 2).

Lessons Learned
This case study demonstrated the importance of making information available to adolescents about where to access all US Food and Drug Administration–approved contraceptive methods, as well as STI and other family planning services, including abortion services, which are often excluded from public education. The results suggest that the mobile app reached NYC adolescents nearly proportionately to their population distribution across the 5 NYC boroughs. One of the exceptions, the overrepresentation of current location searches in Manhattan, may have been related to a large number of adolescents traveling from other boroughs or surrounding suburbs to or through this central borough for school or other reasons.
We observed that searching for providers of sexual health services or contraceptive methods by current location was more popular than searching for them by selecting a borough, perhaps because current location was the default search option. Before the study, we had hypothesized that selecting a borough would be more popular than current location, postulating that adolescents may want to avoid going to a sexual health care provider close to their home or school. Future research should explore whether selecting a borough would be more popular if it were more prominently displayed in an app, perhaps in a map. Whereas individual providers could be mapped in the Teens in NYC mobile app, users were unable to interact directly with a map of providers by borough or by all of NYC.
The comparison of Teens in NYC mobile app search data on contraceptive methods with 2015 YRBS data indicates that the mobile app may have helped adolescents discover a wider range of contraceptive methods than those currently in use. To further support users in finding these methods, we structured the mobile app so that users who searched for contraceptive methods received results listing providers who prescribed and dispensed contraceptives. This decision was informed by Bronx Teens Connection Youth Advisory Board members, who advised that having to visit a pharmacy would be a barrier to accessing contraceptives.
Of note, we emphasized dual protection (eg, using condoms with another contraceptive method) to address pregnancy and STI prevention in the app. We set up the app’s What to Get section to display phrases such as “my birth control + his condoms” or “use with condom every time you have sex” when users accessed this section. In addition, similar messages appeared within the narrative videos 29 in the What to Expect section. Yet, despite these messages, only 8% of searches included the selection of both condoms and another contraceptive method. However, this low number of searches may not fully reflect the impact of these messages because easy access to condoms in NYC public high school health resource rooms and other settings (eg, pharmacies and convenience stores) potentially reduced the need for users of the Teens in NYC app to select condoms in their searches.
Downloads of the Teens in NYC mobile app were driven by media coverage after a May 2013 public launch, as well as by online and transit advertisements. Continuous marketing to reach those entering adolescence and to create exposure when adolescents need sexual health services would likely have further expanded the reach of the Teens in NYC mobile app. This strategy could be used by others who are developing similar apps. Indeed, the Teens in NYC mobile app has inspired apps with similar functionality, including TMI Georgia 34 (formerly gPower 35 ) in Georgia and Oakland Teens 36 in California. Yet, although it would be feasible for more cities and states to launch their own mobile apps, limited resources and the common functionalities required for locally based apps suggest that a national mobile app, particularly one that could be adapted to local needs, may be a more efficient use of limited resources.
Our analysis provides valuable information for those building similar apps. Our observations suggest the importance of allowing for searches: (1) by a range of contraceptive methods and sexual health services, including less widely available services such as abortion services, to serve a broad array of needs; (2) by user’s current location, to provide service information with a convenient point of reference; and (3) by contraceptive methods that are not only prescribed but also dispensed at provider locations, to support ease of access, particularly to less commonly used contraceptive methods.
Limitations
This analysis had several limitations. First, because of NYC DOHMH privacy restrictions for adolescent-focused services, we were unable to use a more robust app analytics software package. As a result, we could not collect data on individual users, and we were unable to group searches by individual user or to evaluate common metrics (eg, user demographic characteristics, user navigation) through the app. Although we did not have an analytics package that assessed the ages of users, a user survey suggested that 77% of users were adolescents (data not shown). Second, at the time this article was finalized, the Teens in NYC mobile app was not available in either Apple or Android app stores, primarily because of a lack of resources needed to update the app to meet current platform operating system specifications.
Conclusion
Although NYC DOHMH is working to identify and secure the resources needed to update and maintain the Teens in NYC mobile app, it is developing a sexual health mobile app that will reach beyond the teen audience, address limitations of analytics, and ensure the broadest reach by expanding the content available for those of different genders and sexual orientations. This evaluation of the Teens in NYC mobile app suggests that mobile apps with search functionality are a valuable way to deliver sexual health service information to adolescents.
