History of Changes
The non-maintenance of ART adherence is a major barrier to the achievement of optimal
treatment outcomes among adolescents living with HIV. ART adherence is a challenge among
adolescents living with HIV because of lack of appropriate information, their unique
emotional state and lifestyles but the most commonly quoted challenge to adherence is
forgetting to take antiretroviral drugs. There is evidence to suggest that short message
service (SMS) reminder- interventions may enhance drug compliance among adolescents living
with other chronic diseases such as asthma and diabetes. Available literature underscores the
need for randomized controlled trials (RCTs) of effective interventions to promote ART
adherence among adolescents with HIV.
The aim of this study is to evaluate the feasibility, acceptability, and efficacy of interactive and tailored SMS reminders on ART adherence among adolescents (15-19 years) living with HIV in Ogun State, Nigeria. The study hypothesizes that the use of personal mobile phones and SMS reminders for the improvement of ART adherence among adolescents living with HIV are feasible, acceptable, and effective.
A single-blind, parallel-design (ratio 1:1), and multi-center RCT of 230 adolescent living with HIV who are non-adherent to medications will be conducted over a one-year period in Southwest Nigeria. All the participants will receive routine adherence counseling during clinic visits and one SMS reminder each for follow-up appointments 48 hours and 24 hours before the follow-up visit date. The intervention group will also receive daily ART adherence reminder SMS. Participants will be assessed at baseline and during follow-up visits at 4, 8, 12, 16 and 20 weeks after the baseline. Baseline assessment of participants will include socio-demographic characteristics; HIV/AIDS risk behaviour assessment, Alcohol and Drug abuse assessment, Client Satisfaction Survey, ART adherence assessment, CD4count and viral load assessments. ART adherence and client satisfaction will be assessed at each follow-up visit while CD4count and viral load assessments will be done at baseline and at 20th week.
It is possible that tailored SMS reminders will mitigate the barrier of forgetfulness in ART-adherence and lead to improved drug compliance, viral suppression, and quality of life among adolescents living with HIV.

Primary Outcome Measures
ART Adherence at 20 Weeks as Determined by VAS, Viral Load
[ Time Frame: 20week [End of study] ]
ART adherence is assessed by different well-validated methods. In this study, ART adherence will be measured, primarily, using the self-report visual analog scale. The scale is well-validated, self-report of the level of ART adherence with a range from 0 to 100%. While higher values indicate better levels of adherence, patients with adherence levels of 95% and above are regarded as ART-adherent while those with values less than 95% are not adherent to ART medications. Viral load is the number of copies of viral RNA detected in participants' blood. Participants with viral load =20 copies per ml are regarded to have optimal viral suppression indicative of optimal adherence to medications.
ART Adherence at 20 Weeks as Determined by Pill Counts, ACTG Adherence Questionnaire, and VAS Scores
[ Time Frame: 20week [End of study] ]
AIDS Clinical Trials Group Scale scores range from 0 to 1. The higher scores reflect better ART adherence Pill count scores also range from 0 to 1 and the higher scores also reflect better adherence. Visual analog scale [VAS] adherence ranges between 0 and 100%. Higher scores reflect better ART adherence
ART Adherence at 20 Weeks as Determined by Viral Load Count
[ Time Frame: 20 week [End of study] ]
Viral load count is measured in copies per ml. The minimum value is 0. There is no maximum value. The higher values reflect poor adherence
ART Adherence at 20 Weeks as Determined by Log of Viral Load Count
[ Time Frame: 20week [End of study] ]
log of viral load count is log 10 transformation of the viral load values
- Patient Satisfaction Score at 20 Weeks
[ Time Frame: End of Study (20weeks) ]
Patient satisfaction will be assessed using a 22-item adaptation of the SERVQUAL tool. It is a multi-dimensional service quality assessment tool that uses a 5-point likert scale scored from 1 to 5 points to assess 5 domains of client satisfaction. The domains are tangibility (4 items; scores from 4 to 20), reliability (5 items; scores from 5 to 25), responsiveness (4 items; scores from 4 to 20), assurance (4 items; scores from 4 to 20), and empathy (5 items; scores from 5 to 25). Patient satisfaction is measured by the total score which will range between 22 and 110. Higher scores indicate better client satisfaction.
- Number of Participants With Mental Distress Determined by General Health Questionnaire 12 at 20 Weeks
[ Time Frame: End of study (20weeks) ]
The General Health Questionnaire 12 (GHQ12) will be used to assess the mental health status of all the participants. It is a well-validated and widely used instrument for screening for mental health distress. It is a 12-item questionnaire that is based on a 4-point likert scale scored from 0 to 3 points. The scores will range between 0 and 36. A score of 12 or more is suggestive of mental distress while scores less than 12 suggest that mental distress is absent.

BACKGROUND In Nigeria, approximately 3.2 million people were living with human
immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in Nigeria. Nigeria
has about 196,000 adolescents (10-19 years) living with HIV with an estimated 17,000 new
infections and 11,000 AIDS-related deaths per year in the age group. Adolescents aged 15 to
19 years constitute 8.8% of Nigeria's over 173 million people and have an HIV prevalence rate
Non-adherence to antiretroviral therapy (ART) increases the risk of non-suppression of HIV, secondary HIV transmission, and development of drug resistance; it has a negative impact on treatment outcomes, leads to decreased survival and worsened quality of life. Adolescents on ART have lower viral suppression rates (49%) when compared with both adults and younger children (72.8% and 57%) and this is one of the most frequent causes of lower adherence to ART.
The non-maintained ART adherence is a major barrier to the achievement of optimal treatment outcomes among adolescents living with HIV. ART adherence is a challenge among adolescents living with HIV because of lack of appropriate information, their unique emotional state and lifestyles. Religious, cultural, social and health services related factors have also been recognized as a source of non-adherence to ART treatment. Other known barriers to ART adherence include difficult dosing schedule, side effects, food restrictions and pill burden but the most commonly quoted challenge to adherence is forgetting to take antiretroviral drugs. Many strategies, including directly observed drug use, adherence counselling, telephone calls and reminder devices adopted to enhance ART adherence have turned out to be time-consuming, costly and intrusive.
With over 148 million active mobile lines, short message service (SMS) has become a common means of communication in Nigeria. SMS is used commonly by teenagers, including those who are economically disadvantaged. SMS has been applied in a variety of healthcare setting because of its low-cost and convenient technology and has proved to be an effective tool for behavioural change interventions. There is evidence to suggest that SMS interventions may enhance drug compliance among adolescents living with other chronic diseases such as asthma and diabetes. An RCT showed that text-messaging system increased adherence to medication among adolescents by about 7%. While studies have evaluated the effectiveness of SMS reminders on ART adherence among PLHIV in some low-resource settings, to the best of our knowledge studies that evaluated SMS reminders for adolescents living with HIV have not yet been published. Indeed, a Cochrane systematic review of randomized controlled trials (RCTs) that assessed the effectiveness of SMS for improving ART adherence among people living with HIV infection identified the need of RCTs for this intervention among adolescents.
Mobile technology communicates interventions to people in real-time and in their natural habitat. A review of the literature on SMS interventions for behavioural change in health care settings identified key characteristics for success such as interactivity and tailored messages.
PROJECT OBJECTIVES Objective 1: To evaluate the efficacy of interactive and tailored SMS reminders on ART adherence among adolescents (15-19 years) living with HIV in Southwest, Nigeria.
Objective 2: To assess the feasibility and acceptability of using personal mobile phones and interactive and tailored SMS reminders for the improvement of ART adherence among adolescents living with HIV in Southwest, Nigeria.
Objective 3: To identify the predictors of ART non-adherence among adolescents (15-19 years) living with HIV in Southwest, Nigeria.
- Interactive and tailored SMS reminders are efficacious in the improvement of ART adherence among adolescents (15-19) years living with HIV.
- The use of personal mobile phones for the improvement of ART adherence among adolescents living with HIV is feasible and acceptable.
- ART adherence among adolescents is predicted by demographic, socioeconomic, and psychosocial factors.
METHODOLOGY Study design and procedure This study is designed to have 80% power to detect a difference of 20%. When the proportion of adolescents who are adherent to ART was taken as 49% (5), a sample size of 104 per group was obtained. The study will recruit 230 participants from the ART clinics in Southwest Nigeria into a randomized controlled trial (RCT). Convenience sampling method by which participants will be recruited on routine clinic visits across five (5) high patient-density ART sites will be used.
For the purpose of this study, we defined poor adherence as self-reported < 95% adherence in the preceding one month using a validated visual analogue scale. Self-reported 95% adherence level is an ideal cut-off point because self-reported measures tend to exaggerate adherence and such high adherence level will minimize the occurrence of false-negatives.
Initial eligibility screening and recruitment will be carried out by the primary caregivers using a checklist. Potential participants who meet the first four criteria will be presented with a visual analogue scale (VAS) labelled 0 to 100% at intervals of 5%. Eligible and willing participants will then be referred to the research assistants for a comprehensive informed consent process.
At the baseline, the research assistants will give the volunteer participants a detailed explanation of the study, including its aim, duration, intervention and possible benefits. All the volunteers will be required to give a signed informed consent in a private room. Adolescents aged 15 to 19 years are thought to be relatively mature. According to a brief of AIDS regulations and Laws in Nigeria, children who are deemed mature in this context are capable of giving informed consent. Besides, based on evidence from South Africa and Lesotho, the WHO recommended that the legal age of consent for HIV testing and treatment should be 12 years. The consenting volunteers will then be allocated unique identifiers that they will maintain throughout the course of the study. The contact details of the lead investigator will be made available to the participants so that he can be reached directly for any reason that is related to the study. Baseline data will be obtained in a private room by trained research assistants using structured interviewer-administered paper-based questionnaires over a period of about 40 minutes. The questionnaire will assess:
Ten millilitres (10 ml) of blood samples will also be taken by laboratory scientists to measure the volunteers' CD4 cell count and HIV viral load. Sampling collection, handling and disposal will follow the standards and guidelines outlined by the WHO and PEPFAR. The participants' capability to operate mobile phones will be enhanced. The research assistants will work with participants to select from a list the most preferred SMS that will serve as a daily reminder of ART adherence. Each participant will select an SMS format that will serve as a reminder for follow-up visit reminders. In addition, the participants will also choose the preferred language and time for SMS reminders. The messages will be designed in such a way that they are sensitive and protect the privacy of the participants. The participants will be able to contact the lead investigator if they wish to change their chosen messages or if the services to their mobile phones are disrupted.
Data Analysis The research assistants will code and enter the data obtained into Microsoft excel software in the CSV format. The data will be exported to the STATA version 15/SE for analyses. The data manager will fully review 5% (one in every twenty) questionnaire for errors. The data manager in conjunction with the investigators will be responsible for baseline, interim and final data analysis. The investigators, data manager, research assistants, counsellors and other project staff will be blinded throughout the study. After the scientific review has been completed and data collection has been completed, at the point of analysis, a list of participants' unique identifiers in two groups will be sent to the data analysts without specifying which the investigation or control group is. The blinding of the clinical database will finally be removed after final data analysis has been completed.
Statistical Methods Intention-to-treat analysis will be carried out. Baseline characteristics will be compared using the chi-square test, rank-sum test, and independent t-test as appropriate. The independent t-test will be used to compare the means of ART adherence between the investigation and control groups after each follow-up visit in order to test if the intervention has any effect. The incidence proportion, incidence rate, relative risk, risk difference, and odds ratio will be used to measure the effect. Survival analysis will also be carried out to adjust for censoring (competing risk and loss to follow-up). Multiple regression analyses will be used to control for possible confounders. Subgroup analysis will also be undertaken in order to generate further hypotheses.
The acceptability of the SMS will be accessed by the responses given by participants. The proportion of participants who find the method acceptable will be determined.
The feasibility will be determined using the proportion of participants who are deemed to have completed the study (participate fully).
The study will also assess client satisfaction and the possible effect of adherence on the mental health status of adolescents. Correlation and linear regression analyses will be used to determine the association between adherence (percent) and mental health status (GHQ 12 measure). Eligibility
