High HIV sero-prevalence among students of institutions of higher education in Southeast Nigeria

The epidemiology of delayed HIV diagnosis in Ibadan, Nigeria

BACKGROUND

Human immunodeficiency virus infection (HIV) is one of the major health burdens in Nigeria. Delayed HIV diagnosis remains a significant driver of HIV transmission. The risk factors of delayed HIV diagnosis have not been widely studied in Nigeria. This observational study examined demographic risk factors for delayed HIV diagnosis and the trends in the annual total cases of delayed HIV diagnosis in Ibadan, Nigeria.

METHODS

We examined the data on HIV patients enrolled in care at the University College Hospital's Antiretroviral Therapy (ART) clinic in Ibadan, Nigeria. Delayed HIV diagnosis was defined as a Cluster of Differentiation 4 (CD4) count of less than 350 cells/mm³ at the time of diagnosis. The association between delayed HIV diagnosis and risk factors was analyzed using logistic regression. The trends in the annual total cases of delayed HIV diagnosis over time were examined.

RESULTS

This study included 3458 HIV patients. There were 1993/3458 prevalent cases of delayed HIV diagnosis (57.6%). The risk factors for delayed HIV diagnosis were older age, retirement, marriage separation, never married, and widowed female. The factors that were significantly associated with a low risk of delayed HIV diagnosis were student and tertiary education. There was a progressive decline in the annual cases of delayed HIV diagnosis.

CONCLUSIONS

Although the cases of delayed HIV diagnosis are still high, they are declining. Human immunodeficiency virus testing should be targeted at populations at risk of delayed diagnosis. Considerable public awareness and education programs about HIV testing may significantly reduce delayed HIV diagnosis in Nigeria.

Implementation of a campus-based and peer-delivered HIV self-testing intervention to improve the uptake of HIV testing services among university students in Zimbabwe: the SAYS initiative

Background

The uptake of HIV testing services among adolescents and young adults in Zimbabwe is low due to stigma associated with the risk of mental and social harm. The WHO recommends HIV self-testing (HIVST) as an innovative approach to improve access to HIV testing for this hard-to-reach populations. This study describes the development and implementation of a coordinated multifaceted and multidisciplinary campus-based approach to improve the uptake of HIV testing among university students in Zimbabwe.

Methods

We utilized both quantitative and qualitative methods guided by the Exploration, Preparation, Implementation, and Sustainment Framework. A formative survey, in-depth interviews, and a scoping review were conducted as part of the situation analysis. Implementers (peer educators and health workers) were trained and community dialogue sessions were conducted to ascertain the determinants (enablers and barriers) influencing both the inner and outer contexts. Self-test kits were disbursed over 6 months before a summative evaluation survey was conducted. Qualitative data were analyzed thematically while the chi-squared test was used to analyze quantitative data.

Results

The formative evaluation showed that 66% of students intended to test and 44% of the enrolled students collected HIVST test kits. Giving comprehensive and tailored information about the intervention was imperative to dispel the initial skepticism among students. Youth-friendly and language-specific packaging of program materials accommodated the students. Despite the high acceptability of the HIVST intervention, post-test services were poorly utilized due to the small and isolated nature of the university community. Implementers recommended that the students seek post-test services off-site to ensure that those with reactive results are linked to treatment and care.

Conclusions

Peer-delivered HIVST using trained personnel was acceptable among adolescents and young adults offered the intervention at a campus setting. HIVST could increase the uptake of HIV testing for this population given the stigma associated with facility-based HTS and the need for routine HIV testing for this age group who may not otherwise test. An off-site post-test counseling option is likely to improve the implementation of a campus-based HIVST and close the linkage to treatment and care gap.

HIV voluntary counselling and testing and behaviour changes among youths in Nigeria

Voluntary counselling and testing (VCT) for HIV has been promoted as a strategy to prevent HIV pandemics by changing sexual behaviour. Despite the provision of VCT in countries with generalized or high-burden epidemics, including Nigeria, the extent of its influence on behavioural change remains a conjecture. The main objective of this study was to examine the influence of HIV VCT on sexual behaviour changes among youths in Nigeria. The study utilized 2013 Nigeria Demographic and Health Survey (NDHS) data. Data were analysed from a nationally representative sample drawn from 8046 females and 6031 males aged 15-24 giving a total sample of 14,077 never-married youths. Descriptive and analytical analyses were carried out, including multivariate logistic regression. The study found a low uptake of HIV VCT and regional variation in behavioural changes between female and male youths. Voluntary HIV counselling and testing was found to be a protective factor for condom use at last sex for female youths, but significantly reduced the likelihood of primary sexual abstinence for both females and males, as well as having a single sexual partner for female youths. After controlling HIV VCT with other variables, certain socioeconomic factors were found to be significantly associated with behavioural changes. Thus, the attitudes of most Nigerian youths towards voluntary HIV counselling and testing needs to be improved through socioeconomic factors for healthy sexual activity. To achieve this, government and non-governmental organizations, as well as religious leaders and policymakers, should engage in appropriate and long-term activities directed at the sexual health needs of never-married youths, through voluntary HIV counselling and testing, to encourage them to change their sexual behaviour.
