Mobile technology access and use among youth in Nairobi, Kenya: implications for mobile health intervention design

User-informed tailoring of electronic and in-person peer navigation strategies to improve retention in HIV care for adolescents and young adults: a qualitative inquiry

Poor adherence and retention in HIV care remain a major challenge among adolescents and young adults (AYA) living with HIV in sub-Saharan Africa (SSA). Strategies are urgently required to support AYA to remain in care for better health outcomes. We explored AYA preferences regarding the format and delivery of electronic and in-person peer navigation to improve HIV care outcomes. This formative qualitative study was conducted among AYA enrolled in HIV care at three clinics in western Kenya. We conducted two focus group discussions (FGDs) each with 8-9 participants (n = 17) purposively selected based on age, gender and clinic where they received care. The characteristics desired of a navigator are a person of the same age group and HIV status who has a good memory and is friendly and able to maintain confidentiality. AYA want the content of their interaction with the navigator to center on sharing motivational messages and also educating them on matters of HIV care, sexual and reproductive health and mental health. The preferred navigation formats for electronic communication are platforms considered confidential. AYA preferred interventions delivered through secure communication platforms by navigators with whom they have commonalities. The navigation interventions that prioritize confidentiality and holistic content will likely be most highly valued by AYA. Furthermore, electronic mechanisms can help support the relationship building that is at the core of our navigation approach and a fundamental aspect of social work in general.

Facilitated WhatsApp Support Groups for Youth Living With HIV in Nairobi, Kenya: Single-Arm Pilot Intervention Study

BACKGROUND

Mobile technology can support HIV care, but studies in youth are limited. In 2014, youth receiving HIV care at several health care facilities in Nairobi, Kenya spontaneously formed peer support groups using the social media platform WhatsApp.

OBJECTIVE

Inspired by youth-initiated groups, we aimed to evaluate the use of WhatsApp to deliver a social support intervention to improve HIV treatment and psychosocial outcomes in youth. We developed a facilitated WhatsApp group intervention (named Vijana-SMART), which was grounded in social support theory and guided by the design recommendations of youth living with HIV. This paper evaluates the intervention's acceptability and pre-post changes in health outcomes.

METHODS

The intervention involved interactive WhatsApp groups facilitated by study staff for 6 months, with each group having approximately 25 members. Study staff sent weekly structured messages, and the message content was based on social support theory and encouraged unstructured peer-to-peer messaging and support. We conducted a single-arm pilot among 55 youth living with HIV aged 14-24 years recruited from a government health care facility serving a mixed-income area of Nairobi. At enrollment and follow-up, self-report questionnaires assessed acceptability; antiretroviral therapy (ART) information, motivation, and behavioral skills (IMB); depression; social support; stigma; resilience; and ART adherence. All participants received the intervention. We used generalized estimating equations (GEEs) clustered by participant to evaluate changes in scores from baseline to follow-up, and correlates of participant WhatsApp messaging.

RESULTS

The median participant age was 18 years, and 67% (37/55) were female. Intervention acceptability was high. All participants reported that it was helpful, and 73% (38/52) sent ≥1 WhatsApp message. Messaging levels varied considerably between participants and were higher during school holidays, earlier in the intervention period, and among youth aged ≥18 years. IMB scores increased from enrollment to follow-up (66.9% to 71.3%; P<.001). Stigma scores also increased (8.3% to 16.7%; P=.001), and resilience scores decreased (75.0% to 70.0%; P<.001). We found no significant change in ART adherence, social support, or depression. We detected a positive association between the level of messaging during the study and the resilience score, but no significant association between messaging and other outcomes. Once enrolled, it was common for participants to change their phone numbers or leave the groups and request to be added back, which may present implementation challenges at a larger scale.

CONCLUSIONS

Increased IMB scores following WhatsApp group participation may improve HIV outcomes. Increased stigma and decreased resilience were unintended consequences and may reflect transient effects of group sharing of challenging experiences, which should be addressed in larger randomized evaluations. WhatsApp groups present a promising and acceptable modality to deliver supportive interventions to youth living with HIV beyond the clinic, and further evaluation is warranted.

Adapt for Adolescents: Protocol for a sequential multiple assignment randomized trial to improve retention and viral suppression among adolescents and young adults living with HIV in Kenya

BACKGROUND

Adolescents and young adults living with HIV (AYAH) aged 14-24 years in Africa experience substantially higher rates of virological failure and HIV-related mortality than adults. We propose to utilize developmentally appropriate interventions with high potential for effectiveness, tailored by AYAH pre-implementation, in a sequential multiple assignment randomized trial (SMART) aimed at improving viral suppression for AYAH in Kenya.

METHODS

Using a SMART design, we will randomize 880 AYAH in Kisumu, Kenya to either youth-centered education and counseling (standard of care) or electronic peer navigation in which a peer provides support, information, and counseling via phone and automated monthly text messages. Those with a lapse in engagement (defined as either a missed clinic visit by ≥14 days or HIV viral load ≥1000 copies/ml) will be randomized a second time to one of three higher-intensity re-engagement interventions: This study will evaluate which interventions and which dynamic sequence of interventions improve sustained viral suppression and HIV care engagement in AYAH at 24 months post-enrollment and assess the cost-effectiveness of successful strategies.

DISCUSSION

The study utilizes promising interventions tailored to AYAH while optimizing resources by intensifying services only for those AYAH who need more support. Findings from this innovative study will offer evidence for public health programming to end the HIV epidemic as a public health threat for AYAH in Africa.

Prevalence and Factors Associated with Risky Sexual Behaviors Among Sexually Active Female Adolescents in Zambia

Despite decades long commitment to women's reproductive health rights, sexually transmitted diseases and unintended pregnancies continue to be major public health concerns in sub-Saharan Africa. In order to provide an evidence base for future policy and services, this study aims to explore the prevalence and factors associated with risky sexual behaviors (RSB) among sexually active Zambian female adolescents using a nationally representative sample. Data on females, aged 15-19 (n = 3000), were obtained from the 2018 Zambia Demographic and Health Survey, an interviewer-administered, nationally representative survey that used multistage sampling. The study conducted multiple logistic regression to explore the correlates of RSB. Of the 3000 respondents, 49.7% (1490) reported ever having sexual intercourse of which 71.1% reported engaging in RSB. Among sexually active female adolescents, the following RSB percentage were reported: intercourse before age 16 (50.6%), nonuse of condoms at last intercourse (37.8%), engaging in transactional sex (6.2%), alcohol use at last intercourse (4.6%), and multiple sexual partners (1.9%). Educational attainment and household wealth showed strong inverse trends with RSB risk and there were notably large geographic differences in RSB within Zambia (22.1% in Lusaka region vs. 62.4% in Western province). The multiple logistic regression results revealed that those who were younger, unmarried, with less than secondary education, without access to Internet, and residents of Western Zambia were significantly more likely to have engaged in RSB (AOR: 1.74-7.69, p < 0.05). Given the negative health outcomes associated with RSB, Zambian adolescent health care programs may strategically target limited resources to the identified risk groups.

Using serious mobile games to improve health literacy in rural Sub-Saharan Africa: A literature review

The African gaming industry is beginning to flourish as a result of a rise in the availability of inexpensive phones and the number of mobile phone subscribers. It has enabled the development and implementation of mobile serious games to promote healthy behavior change in rural communities. This paper examines the use of mobile serious games in healthcare education, with a particular focus on those designed to increase health literacy in rural Africa. Identifying and addressing the design challenges and issues faced by people living in rural African communities through the use of persuasive mobile games can promote behavior change among these underserved communities. We used PubMed, Scopus, Google Scholar and manual search to identify relevant studies published from 2011 to July 2021. The literature review highlights how the identified challenges affect the implementation of persuasive strategies, suggests design solutions for overcoming them, and discusses how persuasive games can be tailored to suit the target rural African populations. Some of the identified challenges are technical in nature (e.g., access to electricity and internet connectivity), while others are not (e.g., language diversity and low literacy). As the number of serious games for healthcare education and awareness continues to increase, it is essential for the successful implementation of inclusive mobile health technologies in rural Africa to identify and address the specific challenges faced by underserved populations such as rural African communities.

Mobile phone ownership, digital technology use and acceptability of digital interventions among individuals on opioid use disorder treatment in Kenya

Background

There is limited research on the use of digital interventions among individuals with opioid use disorders (OUD) in low-and-middle income countries. This study aimed to assess mobile phone ownership, digital technology use and acceptability of digital interventions for treatment among individuals on treatment for OUD in Nairobi, Kenya.

Methods

A cross-sectional study was conducted among individuals with OUD. Structured questionnaires were used to collect data on socio-demographic and clinical characteristics, use of mobile phones and other digital technology and acceptability of digital interventions for treatment.

Results

One hundred and eighty participants were enrolled comprising 83.3% males with mean age of 31.5 years (SD 8.6). Mobile phone ownership was reported by 77.2% of participants of which 59.7% used smartphones. One hundred and sixty-six (92.2%) used phones to call, 82.8 and 77.2% used phones to send and receive text messages respectively; 30% used the internet; 57.2% had replaced the phone in past year and 51.1% of participants reported use of at least one social media platform, of these 44.4% had searched social media for information on drug use. Acceptability to receive treatment by phone was 95% and computer 49.4% with majority (88.1%) preferring a text message-based intervention. The preferred approach of delivery of a text message-based intervention were: one text message per day once a week, message to be personalized and individuals allowed to choose time and day to receive the message. Factors associated with acceptability of digital interventions were education level, being single, smartphone ownership and employment.

Conclusion

Majority of individuals on treatment for OUD had access to mobile phones but with high device turnover and limited access to computers and internet. There was high acceptability of digital interventions to provide treatment for OUDs, mostly through phones. These findings highlight factors to consider in the design of a digital intervention for this population.
