Prevalence, Perpetrators, and Factors Associated With Intimate Partner Violence Among Adolescents Living in Urban Slums of Kampala, Uganda.

Intimate partner violence (IPV) poses a public health burden, yet few studies have assessed co-existence of physical, emotional, and sexual IPV among adolescents. We assessed recent IPV victimization and associated factors and described IPV patterns and perpetrators among young people from urban slums in Kampala, Uganda. We conducted a prospective cohort study among 14 to 19-year-old individuals enrolled from March 2019 to March 2020 and followed quarterly for 12 months. We collected data on socio-demographics, sexual behavior, and substance use through interviews. Recent IPV victimization was documented at all visits if a participant reported experiencing physical, emotional, and/or sexual IPV in the past 3 months. Baseline factors associated with recent IPV victimization were determined using multivariable logistic regression. We enrolled 490 adolescents (60.6% female) with median age 18 years (Interquartile range (IQR) 17-18 years), 91.0% had less than secondary level education. Females mainly engaged in sex work (17.5%) and selling fruits/snacks (9.1%) while males commonly earned from sale of metal scrap or plastic waste (28.5%), 41% reported ≥10 life-time sexual partners, 16.1% were high-risk alcohol drinkers and 34.9% used illicit drugs in the past 3 months. Overall, 27.8% reported recent IPV victimization (20.0% females) with emotional IPV being common (17.8%). At baseline, recent IPV victimization was associated with high-risk alcohol consumption (adjusted odds ratio [aOR] 2.57; 95% confidence interval [CI] [1.44, 4.58]), reported paid sex in the past 3 months (aOR 1.82; [1.02, 3.22]) and being separated (aOR 2.47; [1.29, 4.73]). Recent IPV victimization declined from baseline to month 9 and increased at month 12 visits which coincided with the COVID-19 pandemic. IPV victimization is high among young people living in urban slums with emotional IPV being prevalent. IPV interventions are needed and should also address excessive alcohol consumption.

Oral pre-exposure prophylaxis preference, uptake, adherence and continuation among adolescent girls and young women in Kampala, Uganda: a prospective cohort study.

INTRODUCTION: Oral pre-exposure prophylaxis (PrEP) has been scaled up; however, data from real-world settings are limited. We studied oral PrEP preference, uptake, adherence and continuation among adolescent girls and young women (AGYW) vulnerable to HIV in sub-Saharan Africa. METHODS: We conducted a prospective cohort study among 14- to 24-year-old AGYW without HIV who were followed for 12 months in Kampala, Uganda. Within at least 14 days of enrolment, they received two education sessions, including demonstrations on five biomedical interventions that are; available (oral PrEP), will be available soon (long-acting injectable PrEP and anti-retroviral vaginal ring) and in development (PrEP implant and HIV vaccine). Information included mode and frequency of delivery, potential side effects and method availability. Volunteers ranked interventions, 1 = most preferred to 5 = least preferred. Oral PrEP was "preferred" if ranked among the top two choices. All were offered oral PrEP, and determinants of uptake assessed using Poisson regression with robust error variance. Adherence was assessed using plasma tenofovir levels and self-reports. RESULTS: Between January and October 2019, 532 volunteers were screened; 285 enrolled of whom 265 received two education sessions. Mean age was 20 years (SD±2.2), 92.8% reported paid sex, 20.4% reported ≥10 sexual partners in the past 3 months, 38.5% used hormonal contraceptives, 26.9% had chlamydia, gonorrhoea and/or active syphilis. Of 265 volunteers, 47.6% preferred oral PrEP. Willingness to take PrEP was 90.2%; however, uptake was 30.6% (n = 81). Following enrolment, 51.9% started PrEP on day 14 (same day PrEP offered), 20.9% within 30 days and 27.2% after 30 days. PrEP uptake was associated with more sexual partners in the past 3 months: 2-9 partners (aRR = 2.36, 95% CI: 1.20-4.63) and ≥10 partners (aRR 4.70, 95% CI 2.41-9.17); oral PrEP preference (aRR 1.53, 95% CI 1.08-2.19) and being separated (aRR 1.55, 95% CI 1.04-2.33). Of 100 samples from 49 volunteers during follow up, 19 had quantifiable tenofovir levels (>10 µg/L) of which only three were protective (>40 µg/L). CONCLUSIONS: Half of AGYW preferred oral PrEP, uptake and adherence were low, uptake was associated with sexual behavioural risk and oral PrEP preference. Development of alternative biomedical products should be expedited to meet end-user preferences and, community delivery promoted during restricted movement.

Knowledge, Attitudes, and Practices Regarding COVID-19 among Healthcare Workers in Uganda: A Cross-Sectional Survey.

Healthcare workers (HCWs) are at high risk of COVID-19. However, data on HCWs' knowledge, attitudes, and practices (KAP) toward COVID-19 are limited. Between September and November 2020, we conducted a questionnaire-based COVID-19 KAP survey among HCWs at three hospitals in Uganda. We used Bloom's cut-off of ≥80% to determine sufficient knowledge, good attitude, and good practice, and multivariate Poisson regression with robust variance for statistical analysis. Of 717 HCWs invited to participate, 657 (91.6%) agreed and were enrolled. The mean age (standard deviation) of enrollees was 33.2 (10.2) years; most were clinical HCWs (64.7%) and had advanced secondary school/other higher-level education (57.8%). Overall, 83.9% had sufficient knowledge, 78.4% had a positive attitude, and 37.0% had good practices toward COVID-19. Factors associated with KAP were: Knowledge: being a clinical HCW (aRR: 1.12; 95% CI: 1.02-1.23) and previous participation in health research (aRR: 1.10; 95% CI: 1.04-1.17); Attitude: age > 35 years (aRR: 0.88; 95% CI: 0.79-0.98); Practice: being a clinical HCW (aRR: 1.91; 95% CI: 1.41-2.59). HCWs in Uganda have good knowledge and positive attitude but poor practices towards COVID-19. Differences in COVID-19 KAP between clinical and non-clinical HCWs could affect uptake of COVID-19 interventions including vaccination.

Willingness to participate in COVID-19 vaccine trials; a survey among a population of healthcare workers in Uganda.

BACKGROUND: Healthcare workers (HCWs) are at high risk of acquiring SARS-CoV-2 and COVID-19 and may therefore be a suitable population for COVID-19 vaccine trials. We conducted a survey to evaluate willingness-to-participate in COVID-19 vaccine trials in a population of HCWs at three hospitals in Uganda. METHODS: The survey was conducted between September and November 2020. Using a standardised questionnaire, data were collected on socio-demographics, previous participation in health research, COVID-19 information sources, underlying health conditions, and willingness-to-participate in COVID-19 vaccine trials. Data were analysed descriptively and a binomial generalised linear model with a log link function used to investigate factors associated with unwillingness to participate. RESULTS: 657 HCWs (female, 63%) were enrolled with a mean age of 33 years (Standard Deviation, 10). Overall willingness-to-participate was 70.2%. Key motivating factors for participation were: hope of being protected against COVID-19 (81.1%), altruism (73.3%), and the opportunity to get health care (26.0%). Selected hypothetical trial attributes reduced willingness-to-participate as follows: weekly-quarterly study visits over a 12-month period (70.2%-63.2%, P = 0.026); provision of approximately 50ml of blood at each study visit (70.2%-63.2%, P = 0.026); risk of mild-moderate local adverse reactions (70.2%-60.3%, P<0.001); chance of receiving candidate vaccine or placebo (70.2%-56.9%, P<0.001); and delay of pregnancy [Overall, 70.2%-57.1% P<0.001); Female, 62.8%-48.4% (P = 0.002); Male, 82.5%-71.5% (P = 0.003)]. Collectively, these attributes reduced willingness-to-participate from [70.2%-42.2% (P<0.001) overall; 82.5%-58.1% (P<0.001) in men; 62.8%-32.6% (P<0.001) in women]. Among individuals that were unwilling to participate, the commonest barriers were concerns over vaccine safety (54.6%) and fear of catching SARS-CoV-2 (31.6%). Unwillingness to participate was associated with being female (aRR 1.97, CI 1.46-2.67, P<0.001) and having university or other higher-level education (aRR 1.52, CI 1.05-2.2, P = 0.026). CONCLUSIONS: Willingness-to-participate in COVID-19 vaccine trials among HCWs in Uganda is high but may be affected by vaccine trial requirements and concerns about the safety of candidate vaccines.
