Factors associated with sexually transmitted infections among sexually active men in Ethiopia. Further analysis of 2016 Ethiopian demographic and health survey data

Provincial distribution and factors associated with self-reported sexually transmitted infections and their symptoms among women in Sierra Leone

BACKGROUND

Sexually transmitted infections (STIs) are a significant public health concern worldwide. These infections can have severe consequences for women's health, including pelvic inflammatory disease, infertility, and increased risk of HIV acquisition. Understanding the prevalence and factors associated with STIs among women in Sierra Leone is crucial to developing effective prevention and treatment strategies. This study investigated the provincial distribution and factors associated with self-reported STIs (SR-STIs) and STI symptoms among women in Sierra Leone.

METHODS

The study used data from the 2019 Sierra Leone Demographic and Health Survey, comprising 13,965 women aged 15 to 49 who have ever had sex. Provincial variations in the prevalence of SR-STIs and STI symptoms were presented using a spatial map. A binary logistic regression analysis was performed to assess the factors associated with SR-STIs and STI symptoms among women in Sierra Leone. The results were presented as adjusted odds ratios (aOR) with a 95% confidence interval (CI).

RESULTS

The overall prevalence of SR-STIs and their symptoms was 21.6% [20.4, 22.9] among women in Sierra Leone. Higher odds of SR-STIs and their symptoms were associated with being aged 25-29 (aOR = 1.35, 95% CI = 1.10,1.66), 30-34 (aOR = 1.38, 95% CI = 1.09,1.74), 35-39 (aOR = 1.39, 95% CI = 1.10, 1.77), having tested for HIV (aOR = 1.16, 95% CI = 1.04, 1.29), and having multiple sexual partners (aOR = 2.25, 95% CI = 1.80, 2.83) compared to those in the reference category. Being in the rich wealth index (aOR = 1.32, 95% CI = 1.11, 1.57), living in the Northern (aOR = 2.43, 95% CI = 2.08, 2.83) and Northwestern province (aOR = 3.28, 95% CI = 2.81, 3.83), and being covered by health insurance (aOR = 3.19, 95% CI = 2.62, 3.88) were associated with higher odds of SR-STIs and their symptoms. Lower odds of SR-STIs and their symptoms were found among women with one (aOR = 0.81, 95% CI = 0.68, 0.96), two (aOR = 0.75, 95% CI = 0.61, 0.93), three (aOR = 0.66, 95% CI = 0.53, 0.83), and four or more children (aOR = 0.62, 95% CI = 0.49, 0.77], those residing in rural areas (aOR = 0.81, 95% CI = 0.69, 0.94), and women living in the Southern province (aOR = 0.67, 95% CI = 0.57, 0.80) compared to those in the reference category.

CONCLUSION

The findings indicate that SR-STIs and their symptoms are prevalent among women in Sierra Leone. Our findings underscore the urgent need for targeted public health interventions to address the SR-STIs and their symptoms among women in Sierra Leone. The increased risk among women aged 25-39, those with multiple sexual partners and those from wealthier backgrounds, suggests that educational programmes focusing on safe sexual practices and STI prevention should be prioritized in urban and affluent areas. Additionally, the lower odds of SR-STIs among women with more children and those in rural regions indicate that family dynamics and geographic factors may offer protective benefits, which could be leveraged in public health messaging. Our findings highlight the importance of tailoring health services and outreach efforts to effectively reach and support vulnerable populations, ultimately aiming to reduce the incidence of SR-STIs.

Determinants of care-seeking behavior for sexually transmitted infections among sexually active men in East Africa: A multilevel mixed effect analysis

BACKGROUND

Addressing the global challenge of sexually transmitted infections (STIs) is crucial and demands immediate attention. Raising awareness, improving healthcare facilities, and implementing preventive measures are necessary to reduce the spread and mitigate their adverse effects. The treatment seeking behavior of individuals in relation to STIs is an important factor in STI prevention and control. Thus, this study aimed to identify factors associated with STI-related care-seeking behavior among sexually active men in East Africa.

METHODS

A weighted sample of 3,302 sexually active men from recent Demographic and Health Surveys (DHSs) in East African countries were included for analysis. To accommodate the inherent clustering in DHS data and the binary nature of the dependent variable, we applied a multi-level mixed-effect logistic regression model. The deviance value was used to select the best-fitted model. The strength of the association was estimated using an adjusted odds ratio, along with a 95% confidence interval, and statistical significance was determined at a p-value < 0.05.

RESULT

The pooled prevalence of STI-related care-seeking behavior among sexually active men in East Africa was 71% (95%CI: 69.76, 72.75). In the multivariable multilevel model, individuals in the age groups of 25-34 (AOR = 1.58, 95%CI: 1.22, 2.04) and 44 years and above (AOR = 1.44, 95%CI: 1.01, 2.02), those who were married (AOR = 1.62, 95%CI: 1.25, 2.11), had 1 (AOR = 1.88, 95%CI: 1.50, 2.35) and ≥2 (AOR = 2.53, 95%CI: 1.89, 3.39) sexual partners excluding their spouse, had ever been tested for HIV (AOR = 1.86, 95%CI: 1.52, 2.28), and had media exposure (AOR = 1.30, 95%CI: 1.04, 1.62) had a positive association with care-seeking behavior for STIs.

CONCLUSION

Based on our findings, seven out of ten sexually active men in East Africa exhibit care-seeking behavior for STIs. It is crucial to implement policies and strategies aimed at improving the health-seeking habits of young, unmarried men. Utilizing diverse media platforms to disseminate accurate information and success stories about STI symptoms is pivotal in achieving this goal.

Delay in healthcare seeking and associated factors among patients presenting with sexually transmitted infection symptoms in the Horo Guduru Wollega Zone, Oromia, Western Ethiopia, 2022

Background

Sexually transmitted infections (STIs) are the most prevalent communicable diseases that impact people's health and wellbeing. One of the main obstacles to successful prevention and control of STIs is the delay in seeking healthcare, which can result in significant personal and economic losses. However, there are limited studies on the delay in healthcare seeking among STI patients in resource-limited countries such as Ethiopia.

Objective

This study aims to assess delays in seeking healthcare and associated factors among patients presenting with STIs at public health facilities in the Horo Guduru Wollega Zone, Oromia, Western Ethiopia, 2022.

Methods

A cross-sectional study was conducted at public health facilities in the Horo Guduru Wollega Zone from 15 March to 15 May 2022. The study included 507 participants and used a consecutive sampling method. The outcome variable of the study was the delay in seeking healthcare among STI patients. A binary logistic regression model was used to identify candidate variables with a p-value of less than 0.25 after analyzing each variable separately. Finally, a multivariable analysis was performed to determine statistically significant variables at a p-value of less than 0.05, and an adjusted odds ratio (AOR) was reported.

Results

The proportion of individuals with STIs who delayed seeking healthcare in the Horo Guduru Wollega Zone was 61.3% [95% confidence interval (CI): 57%-65.5%]. Factors such as age >35 years (AOR = 2.23, 95% CI: 1.26-3.95), higher educational level (AOR = 2.72, 95% CI: 1.55-4.74), lack of condom use (AOR = 1.63, 95% CI: 1.05-2.55), and travel time to health facilities of >1 h (AOR = 4.30, 95% CI: 1.70-10.89) were found to be significantly associated with delayed healthcare seeking.

Conclusion and recommendations

This study found that the magnitude of delay in seeking healthcare was higher than the national average and identified several contributing factors. Interventions such as developing educational programs and improving access to healthcare services are crucial for supporting patients with STIs. Enhancing healthcare accessibility in rural areas and promoting the use of condoms through targeted community outreach can reduce travel time and prevent delays in seeking healthcare for STIs.

Feeding modalities, HIV transmission and its predictors among HIV-exposed infants visited Gamo and Gofa zones public health facilities, Southern Ethiopia: a retrospective follow up study

BACKGROUND

Despite the highest (88%) Prevention of Mother-To-Child Transmission (PMTCT) of HIV coverage in Eastern Africa, 50% of new HIV infections in children aged 0-14 years occur in the region.

OBJECTIVE

The aim of this study was to assess the feeding modalities, the rate of HIV transmission and its predictors among HIV exposed infants (HIV-EIs) visited Gamo and Gofa Zones public health facilities, Southern Ethiopia from January 2013 to February 2019.

METHOD AND MATERIALS

Institution-based retrospective follow up study was employed among 450 HIV-EIs having DNA/PCR test results. All infant-mother pair records in selected health facilities were reviewed using a standard data extraction tool from March to July 2019. HIV transmission probabilities were assessed by Kaplan-Meier time-to-event analysis method and log-rank tests were used to compare the risk among different groups. The Cox-proportional hazards model, adjusted on infant feeding modalities and other co-variants was used to identify predictors of HIV transmission, and statistical significance was declared at a p-value of < 0.05.

RESULTS

In total, 383 complete records were analyzed. In the study, 85.6% (95%CI: 81.6%, 89.1%) of HIV-EIs were exclusively breastfed in the first six months. The 18 months probability of infant HIV transmission was 64 (16.7%) (95%CI: 13.1%-20.8%). The risk of HIV-transmission was higher among infants who were delivered at the hospital than health centers/health posts (AHR = 3.07; 95%CI: 1.19, 7.95); discontinued Cotrimoxazole prophylaxis in at least one visit (AHR = 6.32; 95%CI: 3.35, 11.94); did not exclusively breastfeed (AHR = 3.07; 95%CI: 1.72, 5.47) and came from urban areas (AHR = 5.90; 95%CI: 1.40, 24.85).

CONCLUSIONS

The study showed that HIV-EIs had a greater rate of 18 months HIV transmission than the national pooled prevalence. The risk of transmission is higher among infants who do not breastfeed exclusively for the first 6 months, and the risk increases with the number of months spent by breastfeeding. Therefore, strengthening counselling on safer feeding options and Cotrimoxazole prophylaxis use; provision of quality PMTCT service with special focus in hospitals and urban residents were recommended.

Individual and community level factors associated with sexually transmitted infections among men in Tanzania: insights from the Tanzania demographic and health survey of 2022

BACKGROUND

Sexually transmitted infections continue to be a significant public health issue on a global scale. Due to their effects on reproductive and child health as well as their role in facilitating the spread of HIV infection, sexually transmitted infections impose a heavy burden of morbidity and mortality in many developing countries. In addition, stigma, infertility, cancer, and an increased risk of HIV are the primary impacts of STIs on sexual and reproductive health. While numerous studies have been conducted in Tanzania to address this specific topic in various settings, the majority of them weren't representative. Therefore, the main objective of this study was to use data from the most recent Tanzania Demographic and Health Survey in order to evaluate the individual and community-level factors associated with sexually transmitted infections among Tanzanian men at the national level.

METHODS

The most recent datasets from the Tanzania demographic and health survey were used for secondary data analysis. A total of 5763 men participated in this study. The recent Tanzania demographic and health survey provides data for multilevel mixed effect analysis on the variables that contribute to sexually transmitted infections among men in Tanzania. Finally, the percentage and odd ratio were provided, together with their 95% confidence intervals.

RESULT

This study includes a total weighted sample of 5763 men from the Tanzania demographic and health survey. Of the total study participants, 7.5% of men had sexually transmitted infections in the last twelve months. Being married [AOR: 0.531, 95% CI (0.9014, 3.429)] was a factor that reduced the risk of sexually transmitted infections among men. On the other hand, being between the age range of 20 and 24 years [AOR: 6.310, 95% CI (3.514, 11.329)] and having more than one union [AOR: 1.861, 95% CI (1.406, 2.463)] were the factors that increased the risk of sexually transmitted infections among men.

CONCLUSIONS

Men's sexually transmitted infections have been associated with individual-level factors. So, the Tanzanian governments and the concerned stakeholders should provide special attention for men whose age range is 20-24 years old. Promoting marriages and limiting the number of sexual partners should be the main strategies to lower the risk of sexually transmitted infections among men in Tanzania.

Self-reported sexually transmitted infections among men and women in Papua New Guinea: A cross-sectional study

Background and Aims

Sexually transmitted infections (STIs) pose a considerable concern for global healthcare systems. We examined the prevalence and correlates of self-reported STIs (SR-STIs) among men and women in Papua New Guinea.

Methods

A total of 7,195 women and 4,069 men from Papua New Guinea who participated in the 2016-2018 Demographic and Health Survey were included in this study. Percentages were used to summarize the prevalence of SR-STIs among men and women. A multivariable multilevel binary logistic regression was used to examine the correlates of SR-STIs in men and women.

Results

An overall 5.9% and 4.6% prevalence of SR-STIs were recorded among women and men, respectively, in Papua New Guinea. The odds of SR-STIs were higher among women who ever tested for HIV (aOR = 2.47, CI: 1.80-3.39), those who had first sex below 20 years (aOR = 1.76, CI: 1.10-2.80), those who watched television less than once a week (aOR = 1.83, CI: 1.13-2.95) and those from the Highlands and Momase regions (aOR = 5.55, CI: 3.30-9.33) compared to their counterparts who never tested for HIV, who had their first sexual intercourse when they were 20 years and above, who did not watch television at all, and those from the Southern Region. For men, the odds of SR-STIs were high among those who ever tested for HIV (aOR = 1.65, CI: 1.11-2.45), those with one (aOR= 2.08, CI: 1.05-4.14) and two or more (aOR = 3.77, CI: 1.49, 9.52) sexual partners excluding spouse in the 12 months preceding the survey, those living in the Highlands region (aOR = 2.52, CI: 1.48-4.29), and those living in communities with medium literacy level (aOR = 2.33, CI: 1.38-3.94) compared to their counterparts who had never tested for HIV, those with zero sexual partners excluding their spouse in the 12 months preceding the survey, those living in the Southern region, and those living in communities with low literacy levels.

Conclusion

We recommend that the National AIDS Council of Papua New Guinea through the National HIV and STI 2018-2022 Strategy program should be realigned to address these correlates and ensure that more sexual and reproductive health resources are provided to men and women in the Highlands and Momase regions.

Self-reported sexually transmitted infections among adolescent girls and young women in Mali: analysis of prevalence and predictors

OBJECTIVE

To examine the prevalence and predictors of self-reported sexually transmitted infections (SR-STIs) among adolescent girls and young women in Mali.

DESIGN

We performed a cross-sectional analysis of data from the Demographic and Health Survey of Mali, which was conducted in 2018. A weighted sample of 2105 adolescent girls and young women aged 15-24 was included. Percentages were used to summarise the results of the prevalence of SR-STIs. We used a multilevel binary logistic regression analysis to examine the predictors of SR-STIs. The results were presented using an adjusted odds ratio (aOR) with 95% confidence interval (CI). Statistical significance was set at p<0.05.

SETTING

Mali.

PARTICIPANTS

Adolescent girls (15-19 years) and young women (20-24 years).

OUTCOME MEASURE

SR-STIs.

RESULTS

The prevalence of SR-STIs among the adolescent girls and young women was 14.1% (95% CI=12.3 to 16.2). Adolescent girls and young women who had ever tested for HIV, those with one parity, those with multiparity, those with two or more sexual partners, those residing in urban areas, and those exposed to mass media were more likely to self-report STIs. However, those residing in Sikasso and Kidal regions were less likely to report STIs.

CONCLUSION

Our study has shown that SR-STIs are prevalent among adolescent girls and young women in Mali. Health authorities in Mali and other stakeholders should formulate and implement policies and programmes that increase health education among adolescent girls and young women and encourage free and easy access to STI prevention and treatment services.

Sexual violence and self-reported sexually transmitted infections among women in sub-Saharan Africa

Sexual violence has proven to be associated with sexually transmitted infections (STIs) in sub-Saharan Africa (SSA). We examined the association between sexual violence and self-reported STIs (SR-STIs) among women in sexual unions in 15 sub-Saharan African countries. This was a cross-sectional study involving the analysis of data from the Demographic and Health Surveys (DHS) from 15 countries in SSA. A total sample of 65,392 women in sexual unions were included in the final analysis. A multilevel binary logistic regression analysis was carried out and the results were presented using adjusted odds ratios (aOR) at 95% Confidence Interval (CI). Women who experienced sexual violence in the last 12 months were more likely to self-report STIs compared to those who did not experience sexual violence [aOR = 1.76, 95% CI = 1.59-1.94]. Compared to women in Angola, those who were in Mali, Nigeria, Sierra Leone, Uganda, and Liberia were more likely to self-report STIs while those in Burundi, Cameroon, Chad, Ethiopia, Malawi, Rwanda, South Africa, Zambia, and Zimbabwe were less likely to self-report STIs. The study has revealed variations in the country level regarding the prevalence of sexual violence and SR-STI in the last 12 months among women in sexual unions in the selected countries. This study has demostrated that sexual violence in the last 12 months is associated with SR-STIs among women in sexual unions. Moreover, factors that predict SR-STIs were observed in this study. Policymakers and agencies that matter could consider the factors identified in this study when designing policies or strengthening existing ones to tackle STIs among women in SSA. To accelerate the progress towards the achievement of Sustainable Development Goal 3, its imperative efforts and interventions must be intensified in SSA to reduce sexual violence which will go a long way to reduce SR-STIs among women.

Spatial distribution and machine learning prediction of sexually transmitted infections and associated factors among sexually active men and women in Ethiopia, evidence from EDHS 2016

INTRODUCTION

Sexually transmitted infections (STIs) are the major public health problem globally, affecting millions of people every day. The burden is high in the Sub-Saharan region, including Ethiopia. Besides, there is little evidence on the distribution of STIs across Ethiopian regions. Hence, having a better understanding of the infections is of great importance to lessen their burden on society. Therefore, this article aimed to assess predictors of STIs using machine learning techniques and their geographic distribution across Ethiopian regions. Assessing the predictors of STIs and their spatial distribution could help policymakers to understand the problems better and design interventions accordingly.

METHODS

A community-based cross-sectional study was conducted from January 18, 2016, to June 27, 2016, using the 2016 Ethiopian Demography and Health Survey (EDHS) dataset. We applied spatial autocorrelation analysis using Global Moran's I statistics to detect latent STI clusters. Spatial scan statics was done to identify local significant clusters based on the Bernoulli model using the SaTScan™ for spatial distribution and Supervised machine learning models such as C5.0 Decision tree, Random Forest, Support Vector Machine, Naïve Bayes, and Logistic regression were applied to the 2016 EDHS dataset for STI prediction and their performances were analyzed. Association rules were done using an unsupervised machine learning algorithm.

RESULTS

The spatial distribution of STI in Ethiopia was clustered across the country with a global Moran's index = 0.06 and p value = 0.04. The Random Forest algorithm was best for STI prediction with 69.48% balanced accuracy and 68.50% area under the curve. The random forest model showed that region, wealth, age category, educational level, age at first sex, working status, marital status, media access, alcohol drinking, chat chewing, and sex of the respondent were the top 11 predictors of STI in Ethiopia.

CONCLUSION

Applying random forest machine learning algorithm for STI prediction in Ethiopia is the proposed model to identify the predictors of STIs.

Epidemiology of sexually transmitted infections: trends among patients screened for sexually transmitted infections in rwandan health facilities 2014–2020

Background

Sexually Transmitted Infections (STIs) are of great global health concern. Currently, there are limited epidemiological data characterizing STIs in the general population in Rwanda. We assessed the national and regional epidemiology of STIs in Rwanda from 2014–2020 among patients syndromically screened for STIs in all health facilities in Rwanda.

Methods

This is a retrospective analysis of the trend of STIs epidemiology among screened patients at all health facilities in Rwanda using data from the Health Management Information System (HMIS) reporting. Adult patients (15 years and over) screened for STIs between July 2014 and June 2020 were included in the analysis. Outcomes of interest were the number of individuals screened for STIs and individuals diagnosed with at least one STI with a syndromic approach only or plus a test together.

Results

Overall, the number of individuals screened for STIs over the study period was 5.3 million (M) in 2014–2015, 6.6 M in 2015–2016, 6.3 M in 2016–2017, 6.7 M in 2017–2018, 6.2 M in 2018–2019, and 4.9 M in 2019–2020. There was a modest increase in the number of individuals diagnosed and treated for STIs from 139,357 in 2014–15 to 202,294 (45% increase) in 2019–2020. At the national level, the prevalence of STI syndromes amongst individuals screened at health facilities in Rwanda varied between 2.37% to 4.16% during the study period. Among the provinces, Kigali city had the highest prevalence for the whole 6 years ranging from 3.46% (95%CI: 3.41, 3.51) in 2014–2015 to 8.23% (95%CI: 8.15, 8.31) in 2019–2020.

Conclusion

From 2014 to 2020, the number of patients screened for STI syndromes in Rwanda varied between 4.9 M and 6.7 M. However, the prevalence of STIs among screened patients increased considerably over time, which could be associated with public awareness and improved data recording. The highest prevalence of all STIs was observed in urban areas and near borders, and private clinics reported more cases, suggesting the need to improve awareness in these settings and increase confidentiality and trust in public health clinics.

Sexual autonomy and self-reported sexually transmitted infections among women in sexual unions

BACKGROUND

Sexually transmitted infections (STIs) are major public health challenges worldwide. Despite the importance of sexual autonomy in the prevention and control of sexual and reproductive health disorders such as STIs, there are limited studies on the possible relationship between women's sexual autonomy and self-reported STIs, especially in sub-Saharan Africa (SSA). This study, therefore, examined the association between sexual autonomy and self-reported STIs among women in sexual unions in SSA.

METHODS

Data from the Demographic and Health Survey (DHS) of 31 countries in SSA conducted between 2010 and 2019 were analysed. A total of 234,310 women in sexual unions were included in the study. Data were analysed using binary logistic regression models and the results were presented as crude odds ratios (cORs) and adjusted odds ratios (aORs) at 95% confidence interval (CI).

RESULTS

The prevalence of self-reported STIs among women in sexual unions in SSA was 5.8%. Approximately 83.0% of the women surveyed had sexual autonomy. Women who had no sexual autonomy were less likely to have self-reported STIs (cOR=0.52, CI: 0.46-0.54), compared to those who had sexual autonomy. Additionally, higher odds of self-reported STIs were found among women aged 25-29, compared to those aged 15-19 (aOR= 1.21, CI: 1.09-1.35); those who reside in urban areas, compared to those who reside in rural areas (aOR= 1.51, CI: 1.37-1.66) and those who were cohabiting, compared to those who were married (aOR= 1.65, CI: 1.52-1.79). On the other hand, lower odds of self-reported STIs were found among women who were exposed to newspapers (aOR= 0.89, CI: 0.82-0.95), those whose partners had primary education (aOR= 0.84, CI: 0.78-0.91), those who were not exposed to radio (aOR= 0.84, CI: 0.79-0.89), and working women (aOR= 0.86, CI: 0.80-0.93).

CONCLUSIONS

Findings from this study suggest that sexual autonomy is a significant predictor of self-reported STIs among women in sexual unions in SSA. Thus, instituting policies and programs that empower women and improve their levels of sexual autonomy may result in increased self-reporting of symptoms associated with STIs which subsequently help in minimising STI-related complications. Also, policies aimed at enhancing women's sexual autonomy may reduce the burden of STIs in SSA, especially among women in sexual unions.

OUP accepted manuscript

Background

Sexually transmitted infections (STIs) affect individuals of all ages, but adolescent girls and young women are disproportionately affected. We examined the prevalence and factors associated with self-reported STIs (SR-STIs) among adolescent girls and young women in sub-Saharan Africa (SSA).

Methods

Demographic and Health Survey data of 27 sub-Saharan African countries were used for the study. The sample size comprised 68944 adolescent girls and young women (15–24 y of age). The outcome variable was SR-STIs. Multilevel binary logistic regression analysis was performed to identify factors associated with SR-STIs.

Results

On average, the prevalence of SR-STIs among adolescent girls and young women in SSA was 6.92%. The likelihood of SR-STIs was higher among young women aged 20–24 y (adjusted odds ratio [aOR] 1.36 [confidence interval {CI} 1.27 to 1.46]), those not married (aOR 1.64 [CI 1.51 to 1.79]), those working (aOR 1.20 [CI 1.12 to 1.27]), those whose age at first sex was ≤19 y (aOR 1.99 [CI 1.80 to 2.20]), those with two or more sex partners (aOR 1.56 [CI 1.35 to 1.80]), those who listened to radio (aOR 1.26 [CI 1.17 to 1.35]), those in urban areas (aOR 1.42 [CI 1.30 to 1.51]) and those with a wealth index of rich (aOR 1.28 [CI 1.17 to 1.40]) compared with their counterparts. In contrast, those with a primary (aOR 0.86 [CI 0.78 to 0.94]) or secondary/higher level of education (aOR 0.83 [CI 0.75 to 0.92]) compared with those with no formal education and those who were exposed to television (aOR 0.90 [CI 0.84 to 0.98]) compared with those who were not exposed were less likely to report STIs.

Conclusions

Our findings demonstrate the need for countries in SSA to commit towards reducing the incidence of STIs. Community-based health educational programs are required to intensify the awareness of STIs and their prevention in various sub-Saharan African countries considering the factors that expose adolescent girls and young women to STIs.

A Survey of Preclinical Studies Evaluating Nanoparticle-Based Vaccines Against Non-Viral Sexually Transmitted Infections

A worldwide estimate of over one million STIs are acquired daily and there is a desperate need for effective preventive as well as therapeutic measures to curtail this global health burden. Vaccines have been the most effective means for the control and potential eradication of infectious diseases; however, the development of vaccines against STIs has been a daunting task requiring extensive research for the development of safe and efficacious formulations. Nanoparticle-based vaccines represent a promising platform as they offer benefits such as targeted antigen presentation and delivery, co-localized antigen-adjuvant combinations for enhanced immunogenicity, and can be designed to be biologically inert. Here we discuss promising types of nanoparticles along with outcomes from nanoparticle-based vaccine preclinical studies against non-viral STIs including chlamydia, syphilis, gonorrhea, and recommendations for future nanoparticle-based vaccines against STIs.

Self-reported sexually transmitted infections among sexually active men in Ghana

Background

In sub-Saharan Africa, sexually transmitted infections (STIs) other than HIV are major public health problems. This study, therefore, sought to assess the prevalence and factors associated with self-reported STIsamong sexually active men in Ghana.

Methods

Data from the 2014 Ghana demographic and health survey wereused to conduct the study. This research included a total of 3051 sexually active men aged 15–59 years. Self-reported STI was the outcome variable. The data were analyzed using both descriptive (frequencies and percentages) and inferential (binary logistic regression) analysis.

Results

The prevalence of self-reported STIs in the past 12 months preceding the survey was 6.0% (CI:4.7–6.8). Compared to men aged 45-59 years, those aged 25–34 (aOR = 2.96, CI: 1.64–5.35), 15–24 (aOR = 2.19, CI: 1.13–4.26), and 35–44 (aOR = 2.29, CI: 1.23–4.24) were more likely to report an STI. Men who had 2 or more sexual partners apart from their spouse were more likely to report an STI compared to those with no other partner apart from spouse (aOR = 4.24, CI: 2.52–7.14). However, those who had their first sex when they were 20 years and above (AOR = 0.66, CI: 0.47–0.93) and men who read newspaper/magazine had lower odds (aOR = 0.53, CI: 0.37–0.77) of reporting STIs compared to those who had sex below 20 and those who did not read newspaper/magazine respectively.

Conclusion

The study has revealed a relatively low prevalence of self-reported STI among sexually active men in Ghana. Sexually active men aged 25–34 years, those whose age at first sex is below 20 years and those with two or more sexual partners apart from their spouse had higher odds of reporting STIs. However, reading a newspaper was found to be positive in reducing the odds of reporting STIs. To reduce STIs among sexually active men in Ghana, it is important for health systems and stakeholders to consider these factors and put in place measures to mitigate those that put men at risk of STIs and encourage the adoption of the protective factors. Mass media can be used as a useful avenue for encouraging men to report STIs in order to avoid transmitting them to their partners. 

A multi-country cross-sectional study of self-reported sexually transmitted infections among sexually active men in sub-Saharan Africa

Background

Despite the importance of self-reporting health in sexually transmitted infections (STIs) control, studies on self-reported sexually transmitted infections (SR-STIs) are scanty, especially in sub-Saharan Africa (SSA). This study assessed the prevalence and factors associated with SR-STIs among sexually active men (SAM) in SSA.

Methods

Analysis was done based on the current Demographic and Health Survey of 27 countries in SSA conducted between 2010 and 2018. A total of 130,916 SAM were included in the analysis. The outcome variable was SR-STI. Descriptive and inferential statistics were performed with a statistical significance set at p < 0.05.

Results

On the average, the prevalence of STIs among SAM in SSA was 3.8%, which ranged from 13.5% in Liberia to 0.4% in Niger. Sexually-active men aged 25–34 (AOR = 1.77, CI:1.6–1.95) were more likely to report STIs, compared to those aged 45 or more years. Respondents who were working (AOR = 1.24, CI: 1.12–1.38) and those who had their first sex at ages below 20 (AOR = 1.20, CI:1.11–1.29) were more likely to report STIs, compared to those who were not working and those who had their first sex when they were 20 years and above. Also, SAM who were not using condom had higher odds of STIs (AOR = 1.35, CI: 1.25–1.46), compared to those who were using condom. Further, SAM with no comprehensive HIV and AIDS knowledge had higher odds (AOR = 1.43, CI: 1.08–1.22) of STIs, compared to those who reported to have HIV/AIDS knowledge. Conversely, the odds of reporting STIs was lower among residents of rural areas (AOR = 0.93, CI: 0.88–0.99) compared to their counterparts in urban areas, respondents who had no other sexual partner (AOR = 0.32, CI: 0.29–0.35) compared to those who had 2 or more sexual partners excluding their spouses, those who reported not paying for sex (AOR = 0.55, CI: 0.51–0.59) compared to those who paid for sex, and those who did not read newspapers (AOR = 0.93, CI: 0.86–0.99) compared to those who read.

Conclusion

STIs prevalence across the selected countries in SSA showed distinct cross-country variations. Current findings suggest that STIs intervention priorities must be given across countries with high prevalence. Several socio-demographic factors predicted SR-STIs. To reduce the prevalence of STIs among SAM in SSA, it is prudent to take these factors (e.g., age, condom use, employment status, HIV/AIDS knowledge) into consideration when planning health education and STIs prevention strategies among SAM.
