Exploring Determinants of Condom Use among University Students in Sudan

Development of a risk estimation model for condomless sex among college students in Zhuhai, China: a cross-sectional study

BACKGROUND

Condom use at last intercourse is an effective indicator for human immunodeficiency virus (HIV) prevention. To identify at-risk individuals and improve prevention strategies, this study explored factors associated with condomless sex at last intercourse in the last year and developed a risk estimation model to calculate the individual possibility of condomless sex among college students in Zhuhai, China.

METHODS

A cross-sectional study was conducted among 1430 college students who had sex in the last year from six universities in Zhuhai. The least absolute shrinkage and selection operator (LASSO) and logistic regression were performed to explore the predictors of condomless sex. The nomogram was constructed to calculate the individual possibility of condomless sex. Discrimination and calibration of the nomogram were evaluated using the area under the receiver-operator characteristic curve (AUROC) and the calibration curve.

RESULTS

The proportion of students who had condomless sex at last intercourse was 18.2% (260/1430). Students who had experienced more types of intimate partner violence (aOR, 1.58; 95% CI, 1.31 ~ 1.92) and had anal sex (aOR, 1.75; 95% CI, 1.06 ~ 2.84) were more likely to have condomless sex. Students who had heterosexual intercourse (aOR, 0.37; 95% CI, 0.21 ~ 0.70), used condoms at first sex (aOR, 0.20; 95% CI, 0.14 ~ 0.27), had high attitudes towards condom use (aOR, 0.87; 95% CI, 0.80 ~ 0.95) and self-efficacy for condom use (aOR, 0.84; 95% CI, 0.78 ~ 0.90) were less likely to have condomless sex. The nomogram had high accuracy with an AUROC of 0.83 and good discrimination.

CONCLUSIONS

Intimate partner violence, anal sex, condom use at first sex, attitude towards condom use, and self-efficacy for condom use were associated with condomless sex among college students. The nomogram was an effective and convenient tool for calculating the individualized possibility of condomless sex among college students. It could help to identify individuals at risk and help universities and colleges to formulate appropriate individualized interventions and sexual health education programs.

Prevalence and circulant genotypes of Chlamydia trachomatis in university women from cities in the Brazilian Amazon

BACKGROUND

Approximately 80% of infected women infected by Chlamydia trachomatis are asymptomatic, although this infection can lead to serious complications in the female reproductive tract. Few data on Chlamydia infection and genotypes are available in Amazonian communities.

OBJECTIVES

To describe the prevalence of and associated factors and to identify the genotypes of sexual C. trachomatis infection in female university students in different urban centers (capital and interiors) in the Brazilian state of Pará, in the eastern Amazon region.

METHODS

A cross-sectional study was performed among young women attending public universities in four different urban centers in the eastern Amazon region. They were invited to participate in the studt and cervical secretions were collected for molecular diagnosis of C. trachomatis. We utilized amplification of the ompA gene by nested PCR. Positive samples were genotyped by nucleotide sequencing. Study participants completed a questionnaire on social, epidemiological, and reproductive health variables. A Qui-square and Binominal regression test were used to evaluate the degree of association of these variables with the infection.

RESULTS

A total of 686 female students was included in the study. The overall prevalence of C. trachomatis was 11.2% (77/686). The prevalence of this infection was higher in interiors (15.2% vs 9.5%/ p: 0.0443). Female university students who do not have a sexual partner (11.8%/p <0.008), who do not use a condom in their sexual relations (17.8%/p <0.0001) and who reported having suffered a miscarriage (32%/p <0.0001) have high chances of acquiring this sexual infection. The ompA gene was sequenced in only 33 (42.8%) samples, revealing the genotype J was the most frequent (27.2% [9/33]), followed by genotypes D (24.2% [8/33]), and then genotypes F (18.2% [6/33]), E (15.1% [5/33]) K (6.1% [2/33]), Ia (6.1% [2/33]), and G (3.1% [1/33]).

CONCLUSIONS

The high prevalence of sexual infection by C. trachomatis in the female university students from the interior of the state of Pará, individuals with no fixed sexual partner, those that had had a miscarriage, the students that do not use condoms in their sexual relations. The genotype J of C. trachomatis genotypes was the most frequent. These data are important to help defining the epidemiological effects of chlamydial infections in Amazonian populations.

Assessing Condom Use and Views on HIV Counselling and Testing among TVET College Students in Limpopo Province, South Africa

South Africa's population is predominantly young, presenting a powerful resource for the country. Despite this, adolescents and young people remain at the epicentre of the HIV epidemic, particularly adolescent girls and young women (AGYW). There are limited studies that investigate the views on HIV Counselling and Testing (HCT) and condom use among adolescents and young people, and college students in particular, in South Africa. This cross-sectional study assessed condom use among college students and their views and opinions on HCT. Utilising an adapted questionnaire from the Australian Secondary students and the South African Sexual Health survey, the data from 396 students were analysed using univariate and multiple logistic regression performed using Stata IC version 16. The majority of the students (n = 339, 85.8%) had a sexual partner at the time of the study. Our findings reveal a relatively high occurrence of condom use in the last sexual encounter (n = 225, 60%) and high HCT uptake (n = 50, 88.4%). Females were generally more comfortable regarding HIV services compared to their male counterparts. More than half, 54.6% vs. 36.0% were comfortable about testing, 34.0% vs. 48.3% felt very scared about testing for HIV, 3.6% vs. 10.1% reported that they were not ready to take an HIV test, 7.6% vs. 5.6% intended getting tested soon (p = 0.0002). Condom use was significantly associated with the use of a condom during the first sexual encounter (aOR = 4.71, 95% CI: 2.14, 10.37) and knowing their partner's HIV status (aOR = 2.08, 95% CI: 1.19-3.65). The HCT and condom promotion strategies implemented by Higher Health in TVET colleges is showing success and colleges in other parts of the region could emulate these best practices. Program developers should consider tailor-made combinations of prevention interventions that would appeal to both female and male college students to improve condom use and uptake of HIV testing services.

Psychosocial determinants of consistent condom use among university students in Sudan: findings from a study using the Integrated Change Model

Unprotected sex is common among university students in Sudan, thus increasing risks for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV). As little is known about the psychosocial determinants of consistent condom use among this population, this study was designed to identify them. The Integrated Change Model (ICM) was applied in a cross-sectional design to identify in 218 students (aged 18-25 years) from Khartoum which items distinguish condom users from non-condom users. Condom users differed significantly from non-condom users in having more HIV and condom use-related knowledge, higher perception of susceptibility to HIV, reporting more exposure to condom use cues, having a less negative attitude towards condom use (attitude cons), experiencing social support and norms favouring condom use and having higher condom use self-efficacy. Binary logistic regression showed that peer norms favouring condom use in addition to HIV-related knowledge, condom use cues, negative attitude and self-efficacy were the factors uniquely associated with consistent condom use among university students in Sudan. Interventions seeking to promote consistent condom use among sexually active students could benefit from increasing knowledge about HIV transmission and prevention, raising HIV-risk perception, using condom use cues, addressing perceived condom disadvantages and enhancing students` self-efficacy to avoid unprotected sex. Moreover, such interventions should raise students` perceptions of their peers` beliefs and behaviours favouring condom use and seek health care professionals` and religious scholars` support for condom use.

Universitários e o Uso do Preservativo como Método de Prevenção das Infecções Sexualmente Transmissíveis

Resultados: Dos 162 participantes, 64.8% possuíam conhecimento adequado; 52.5%, atitude adequada; e 98.1%, prática inadequada em relação à prevenção. O conhecimento esteve associado com a religião (p=0.015), frequência de realização de testes rápidos (p=0.016) e diagnóstico prévio de IST (p=0.029); a atitude esteve associada com a renda familiar (p=0.027), procedência (p=0.017) e sexo (p=0.000); houve associação da prática com o relacionamento (p=0.040). Discussão: O acesso apropriado a meios de prevenção e de informações favorece melhores atitudes e práticas em relação ao uso dos preservativos. Conclusão: Os universitários podem estar vulneráveis às IST, sendo importante ações educativas voltadas à adesão do preservativo.

Beliefs regarding COVID-19 vaccinations of young adults in the United Kingdom: An interview study applying the Integrated Change Model

INTRODUCTION

Young adults are considered one of the most hesitant groups towards getting vaccinated in the UK, which threatens the success of the vaccination program in ending the pandemic. Identifying and understanding the socio-cognitive beliefs is important to effectively design and implement health communication interventions. Therefore, the aim of this study was to identify the underlying beliefs regarding COVID-19 vaccinations among young adults in the UK.

METHODS

The study consisted of online, one-on-one interviews with 18 individuals (6 males, 12 females) aged between 18 and 29 years, conducted in June 2021. The guiding theoretical framework was the I-Change Model. Interviews were recorded and transcribed verbatim. The transcripts were independently coded by two researchers by using the constructs of the I-Change Model. Belief statements were elicited from the codes and the frequency of belief statements was recorded and compared between intenders and non-intenders.

RESULTS

Similar beliefs were observed in intenders and non-intenders for most constructs of the I-Change Model. However, non-intenders distinguished themselves from intenders by their higher perceived risks of side effects and higher perceived disadvantages of being vaccinated. Non-intenders expressed the belief that the risk of unknown or long-term side effects, such as blood clotting and impact on fertility, were the main reason for them not to be willing to vaccinate. In addition, in both groups, participants had mostly similar beliefs as their friends and family.

CONCLUSION

This research provides insights in the specific beliefs of the young adult population of the UK regarding COVID-19 vaccinations, which could have implications for health communication interventions. The findings suggest that such interventions should focus on reducing the uncertainty regarding short- and long-term effects and potentially having a focus on the entire social environment of young adults.

Differences in Sexual Behavior and Partner Notification for Sexually Transmitted Infections Between the Out of School Youth and University Students in a Peri-Urban District in South Africa-A Cross-Sectional Survey

The increase in sexually transmitted infections (STIs) in young people is a public health concern. Among those in university and out of school, different contextual factors contribute to their risky sexual behavior and increased susceptibility to STIs and HIV. There are limited comparative studies examining risky sexual behavior and partner notification (PN) between these two groups, particularly in South Africa. We investigated sexual behaviors, self-reported STI diagnosis, health seeking behavior, and preferred PN methods of university students and out of school youth. A descriptive cross-sectional survey was used using convenient sampling to select 917 students across five health sciences universities and through periodic sampling 699 out of school youth were selected from two main local shopping centers in South Africa. Descriptive statistics, bivariate and multivariable logistic analysis were performed using Stata IC version 14. More university students (71.7%) than out of school youth were in casual relationships (28.3%), with half of out of school youth being in steady relations (50.2%). Moreover, university students (65.7%) used a condom in the past 6 months compared to their counterparts (34.3%). Of the 124 youth who were diagnosed with STI in the past 12 months, majority (n = 106, 85%) were out of school youth. The probability of notifying a partner about a STI infection was 82% among university students compared to their counterparts (p = >0.05). The odds of notifying a partner was 1.79 times more for those having multiple sexual partners than those who had only one partner. Both groups preferred a face-to-face STI disclosure with partner; however, more university students (67%) preferred SMS notification than PN referral slips as compared to out of school youth (42%). Both the university students and the out of school youth engaged in risky sexual behaviors. Both groups preferred face-to-face and clinic SMS partner notifications, even though university students were in the majority. There is a need for developing health promotion scripts on disclosing STIs to sexual partners to empower the majority of the youth who prefer face-to-face PN over the prescribed methods.

Low awareness of oral and injectable PrEP among high-risk adolescent girls and young women in Kampala, Uganda

BACKGROUND

Adolescent girls and young women (AGYW) account for a disproportionate number of new HIV infections worldwide. HIV prevalence among young sex workers in Uganda is 22.5%. Although pre-exposure prophylaxis (PrEP) is a highly effective biomedical HIV prevention method, awareness of PrEP among AGYW in Uganda has not been studied systematically. We aimed to assess awareness of PrEP and factors associated with awareness of PrEP among AGYW who frequently reported paid sex.

METHODS

We conducted a cross-sectional study among 14-24-year old AGYW at high risk of HIV infection in Kampala, Uganda from January to October 2019. Participants were screened for PrEP eligibility using a national screening tool of whom 82.3% were eligible. Data on socio-demographics, behavioral and sexual risks were collected by interview. Awareness of oral or injectable PrEP, the latter of which is currently in late-stage trials, was defined as whether an individual had heard about PrEP as an HIV prevention method. Multivariable robust poisson regression model was used to assess factors associated with oral PrEP awareness.

RESULTS

We enrolled 285 participants of whom 39.3% were under 20 years old, 54.7% had completed secondary education, 68.8% had multiple sex partners in the past 3 months, 8.8% were screened as high risk drinkers'/ alcohol dependent (AUDIT tool) and 21.0% reported sex work as main occupation. Only 23.2% were aware of oral PrEP and 3.9% had heard about injectable PrEP. The prevalence of oral PrEP awareness was significantly higher among volunteers screened as alcohol dependents (aPR 1.89, 95% CI 1.08-3.29) and those with multiple sexual partners (aPR 1.84, 95% CI 1.01-3.35), but was lower among those who reported consistent condom use with recent sexual partners (aPR 0.58, 95% CI 0.37-0.91).

CONCLUSIONS

Majority of AGYW were not aware of any kind of PrEP. Those with higher risk behavior, i.e. alcohol dependents or multiple sexual partners, were more aware of oral PrEP. Interventions to increase awareness among female youth are needed. Improving PrEP awareness is critical to increasing PrEP uptake among high-risk AGYW in Uganda.

Conocimientos y percepción de estudiantes de psicología sobre el trabajo profesional en personas con VIH

Los psicólogos que se dedican a la atención de personas diagnosticadas con VIH es necesario que cuenten con una actitud favorable hacia el trabajo profesional que impacte en una mejor atención; además es necesario que como profesionales de la salud, también tengan un comportamiento sexual saludable, de tal manera que haya congruencia entre lo que hace y lo que transmite como profesional. Con base en lo anterior, se tienen dos objetivos: (1) conocer el nivel de conocimientos sobre VIH/SIDA, creencias y uso del condón en relaciones sexuales estudiantes de psicología; y (2) conocer su percepción sobre VIH y del trabajo profesional con personas diagnosticadas con VIH. Se evaluó a 439 estudiantes de psicología, en términos generales se encontró que tienen un nivel aceptable de conocimientos sobre VIH, pero no sobre el uso del condón; tienen creencias favorables hacia su uso, pero no implica que sean consistentes en su uso; también se encontró una valoración positiva hacia la atención de personas con VIH. Se discute en términos de la importancia de formar a los estudiantes sobre la importancia de su salud sexual y en cómo trabajar con personas con VIH.

Development and Evidence of the Validity of the Condom Use Attitudes Scale for Youth and Adults in a Chilean Context

Condom use is the most effective preventive behavior against HIV transmission, and its inadequate use is a public health problem that occurs mostly among youth and young adults. Although there are scales that measure condom use, those that exist correspond to English-speaking developments or do not have psychometric evidence to support them, so it is possible that the available adaptations of instruments do not adequately reflect the phenomenon in the Chilean population. Thus, the study aims to develop a scale to assess attitudes toward condom use in Chilean youth and young adults. Initially, a sample of students between 18 and 39 years (n = 520) was used for debugging the instrument. Then, a second sample was taken from the general population aged 18 to 40 (n = 992) to confirm the factor structure of the proposed model. The final scale has 10 items and 3 attitudinal dimensions (affective, cognitive, and behavioral). The results show that the identified structure provides adequate levels (ω > 0.7) or at least sufficient of reliability (ω > 0.6) and presents evidence of validity, based on the internal structure of the test, through ESEM (CFI = 0.993; TLI = 0.984; RMSEA = 0.056). In addition, evidence of validity was obtained based on the relationship with other variables and strong invariance between the scores of men and women. It is concluded that the scale developed has adequate psychometric properties to assess, in brief form, condom use attitudes in equal samples for research and screening purposes.

A spatial analysis of the epidemiology of HIV-infected students in Zhejiang province, China

BACKGROUND

The upsurge in HIV infections among students is a matter of particular concern. However, few studies have explored the epidemiological characteristics including the risky sexual networking of HIV-infected students in Zhejiang province, China.

METHODS

Using the provincial surveillance data of HIV-infected students, we conducted a retrospective epidemiology study to describe the epidemiological characteristics of 628 newly diagnosed cases from 2011 to 2016 and detailed information of 124 cases from 2015 to 2016. Spatial analyses were conducted using ArcGIS software, and statistical analyses were performed using SPSS software.

RESULTS

A total of 628 cases of HIV/AIDS were diagnosed among students in Zhejiang Province, China between 2011 and 2016. The cases showed an overall increasing trend over time, while the proportions of students with HIV disease status, cases diagnosed by HIV voluntary counseling and testing (VCT), and cases of homosexual transmission remained stable over time. Significant spatial heterogeneity in the cases was seen at the county level. Detailed data on 124 HIV-positive individuals collected from the local Center for Disease Control and Prevention (CDC) from 2015 and 2016, showed that the majority of them (85.5%,) engaged in homosexual behavior, and 93.4% had sex with casual partners. These partners included not only social members, but also other students. Online dating applications represented the most common means of seeking and communicating with homosexual partners. The level of awareness regarding the risk of HIV infection, and the amount coverage of face-to-face education towards students were both low.

CONCLUSIONS

HIV infections among students were characterized by increasing trend and spatial clustering in Zhejiang Province between 2011 and 2016, with homosexual sexual activity being the main mode of infection. Interventions are urgently required to prevent HIV infection in this population by increasing awareness of the disease. HIV testing programs and information regarding disease prevention specifically through online dating applications are needed.
