Prevalence of overweight and obesity among adolescents living with HIV after dolutegravir - based antiretroviral therapy start in Kampala, Uganda.

BACKGROUND: Dolutegravir (DTG)-based antiretroviral therapy (ART) is currently the preferred first-line treatment for persons living with HIV (PLHIV) including children and adolescents in many low- and middle-income countries including Uganda. However, there are concerns about excessive weight gain associated with DTG especially in adults. There remains paucity of current information on weight-related outcomes among adolescents on DTG. We determined the prevalence of excessive weight gain and associated factors among adolescents living with HIV (ALHIV) receiving DTG-based ART in Kampala, Uganda. METHODS: Cross-sectional study involving ALHIV aged 10-19 years on DTG-based ART for at least one year were recruited from public health facilities in Kampala between February and May 2022. Excessive weight gain was defined as becoming overweight or obese per body mass index (BMI) norms while on DTG-based ART for at least one year. Demographic, clinical and laboratory data were collected using interviewer-administered questionnaires and data extracted from medical records. At enrolment, blood pressure and anthropometry were measured and blood was drawn for blood glucose and lipid profile. Data was summarised using descriptive statistics and logistic regression was performed to determine the associated factors. RESULTS: We enrolled 165 ALHIV with a median age of 14 years (IQR 12-16). Eighty (48.5%) were female. The median duration on ART and DTG was 8 years (IQR 7-11) and 2 years (IQR 1-3) respectively. At DTG initiation, the majority of participants (152/165, 92.1%) were ART-experienced, and had normal BMI (160/165, 97%). Overall, 12/165 (7.3%) adolescents (95% CI: 4.2-12.4) had excessive weight gain. No factors were significantly associated with excessive weight gain after DTG start in ALHIV. However, all ALHIV with excessive weight gain were females. CONCLUSION: Our study found a prevalence of 7.3% of overweight and obesity in ALHIV after initiating DTG. We did not find any factor significantly associated with excessive weight gain in ALHIV on DTG. Nonetheless, we recommend ongoing routine monitoring of anthropometry and metabolic markers in ALHIV as DTG use increases globally, to determine the exact magnitude of excessive weight gain and to identify those at risk of becoming overweight or obese while taking the medication.

High blood pressure and associated factors among HIV-infected young persons aged 13 to 25 years at selected health facilities in Rwenzori region, western Uganda, September-October 2021.

BACKGROUND: High blood pressure (HBP), including hypertension (HTN), is a predictor of cardiovascular events, and is an emerging challenge in young persons. The risk of cardiovascular events may be further amplified among people living with HIV (PLHIV). We determined the prevalence of HBP and associated factors among PLHIV aged 13 to 25 years in Rwenzori region, western Uganda. METHODS: We conducted a cross-sectional study among PLHIV aged 13 to 25 years at nine health facilities in Kabarole and Kasese districts during September 16 to October 15, 2021. We reviewed medical records to obtain clinical and demographic data. At a single clinic visit, we measured and classified BP as normal (< 120/ < 80 mmHg), elevated (120/ < 80 to 129/ < 80), stage 1 HTN (130/80 to 139/89), and stage 2 HTN (≥ 140/90). We categorized participants as having HBP if they had elevated BP or HTN. We performed multivariable analysis using modified Poisson regression to identify factors associated with HBP. RESULTS: Of the 1,045 PLHIV, most (68%) were female and the mean age was 20 (3.8) years. The prevalence of HBP was 49% (n = 515; 95% confidence interval [CI], 46%-52%), the prevalence of elevated BP was 22% (n = 229; 95% CI, 26%-31%), and the prevalence of HTN was 27% (n = 286; 95% CI, 25%-30%), including 220 (21%) with stage 1 HTN and 66 (6%) with stage 2 HTN. Older age (adjusted prevalence ratio [aPR], 1.21; 95% CI, 1.01-1.44 for age group of 18-25 years vs. 13-17 years), history of tobacco smoking (aPR, 1.41; 95% CI, 1.08-1.83), and higher resting heart rate (aPR, 1.15; 95% CI, 1.01-1.32 for > 76 beats/min vs. ≤ 76 beats/min) were associated with HBP. CONCLUSIONS: Nearly half of the PLHIV evaluated had HBP, and one-quarter had HTN. These findings highlight a previously unknown high burden of HBP in this setting's young populations. HBP was associated with older age, elevated resting heart rate, and ever smoking; all of which are known traditional risk factors for HBP in HIV-negative persons. To prevent future cardiovascular disease epidemics among PLHIV, there is a need to integrate HBP/HIV management.

Investigation of a COVID-19 outbreak at a regional prison, Northern Uganda, September 2020.

Despite implementing measures to prevent introduction of COVID-19 in prisons, a COVID-19 outbreak occurred at Moroto Prison, northern Uganda in September 2020. We investigated factors associated with the introduction and spread of COVID-19 in the prison. A case was PCR-confirmed SARS-CoV-2 infection in a prisoner/staff at Moroto Prison during August-September 2020. We reviewed prison medical records to identify case-patients and interviewed prison and hospital staff to understand possible infection mechanisms for the index case-patient and opportunities for spread. In a retrospective cohort study, we interviewed all prisoners and available staff to identify risk factors. Data were analyzed using log-binomial regression. On September 1, 2020, a recently-hospitalized prisoner with unrecognized SARS-CoV-2 infection was admitted to Moroto Prison quarantine. He had become infected while sharing a hospital ward with a subsequently-diagnosed COVID-19 patient. A sample taken from the hospitalized prisoner on August 20 tested positive on September 3. Mass reactive testing at the prison on September 6, 14, and 15 revealed infection among 202/692 prisoners and 8/90 staff (overall attack rate=27%). One prison staff and one prisoner who cared for the sick prisoner while at the hospital re-entered the main prison without quarantining. Both tested positive on September 6. Food and cleaning service providers also regularly transited between quarantine and unrestricted prison areas. Using facemasks >50% of the time (adjusted risk ratio [aRR]=0.26; 95%CI: 0.13-0.54), or in combination with handwashing after touching surfaces (aRR=0.25; 95%CI: 0.14-0.46) were protective. Prisoners recently transferred from other facilities to Moroto Prison had an increased risk of infection (aRR=1.50; 95%CI: 1.02-2.22). COVID-19 was likely introduced into Moroto Prison quarantine by a prisoner with hospital-acquired infection and delayed test results, and/or by caretakers who were not quarantined after hospital exposures. The outbreak may have amplified via shared food/cleaning service providers who transited between quarantined and non-quarantined prisoners. Facemasks and handwashing were protective. Reduced test turnaround time for the hospitalized prisoner could have averted this outbreak. Testing incoming prisoners for SARS-CoV-2 before quarantine, providing unrestricted soap/water for handwashing, and universal facemask use in prisons could mitigate risk of future outbreaks.

Investigation of possible preventable causes of COVID-19 deaths in the Kampala Metropolitan Area, Uganda, 2020-2021.

BACKGROUND: Identifying preventable causes of COVID-19 deaths is key to reducing mortality. We investigated possible preventable causes of COVID-19 deaths over a six-month period in Uganda. METHODS: A case-patient was a person testing reverse transcription polymerase chain reaction-positive for SARS-CoV-2 who died in Kampala Metropolitan Area hospitals from August 2020 to February 2021. We reviewed records and interviewed health workers and case-patient caretakers. RESULTS: We investigated 126 (65%) of 195 reported COVID-19 deaths during the investigation period; 89 (71%) were male, and the median age was 61 years. A total of 98 (78%) had underlying medical conditions. Most (118, 94%) had advanced disease at admission to the hospital where they died. A total of 44 (35%) did not receive a COVID-19 test at their first presentation to a health facility despite having consistent symptoms. A total of 95 (75%) needed intensive care unit admission, of whom 45 (47%) received it; 74 (59%) needed mechanical ventilation, of whom 47 (64%) received it. CONCLUSION: Among hospitalized patients with COVID-19 who died in this investigation, early opportunities for diagnosis were frequently missed, and there was inadequate intensive care unit capacity. Emphasis is needed on COVID-19 as a differential diagnosis, early testing, and care-seeking at specialized facilities before the illness reaches a critical stage. Increased capacity for intensive care is needed.

Risk perception and psychological state of healthcare workers in referral hospitals during the early phase of the COVID-19 pandemic, Uganda.

BACKGROUND: Safeguarding the psychological well-being of healthcare workers (HCWs) is crucial to ensuring sustainability and quality of healthcare services. During the COVID-19 pandemic, HCWs may be subject to excessive mental stress. We assessed the risk perception and immediate psychological state of HCWs early in the pandemic in referral hospitals involved in the management of COVID-19 patients in Uganda. METHODS: We conducted a cross-sectional survey in five referral hospitals from April 20-May 22, 2020. During this time, we distributed paper-based, self-administered questionnaires to all consenting HCWs on day shifts. The questionnaire included questions on socio-demographics, occupational behaviors, potential perceived risks, and psychological distress. We assessed risk perception towards COVID-19 using 27 concern statements with a four-point Likert scale. We defined psychological distress as a total score > 12 from the 12-item Goldberg's General Health Questionnaire (GHQ-12). We used modified Poisson regression to identify factors associated with psychological distress. RESULTS: Among 335 HCWs who received questionnaires, 328 (98%) responded. Respondents' mean age was 36 (range 18-59) years; 172 (52%) were male. The median duration of professional experience was eight (range 1-35) years; 208 (63%) worked more than 40 h per week; 116 (35%) were nurses, 52 (14%) doctors, 30 (9%) clinical officers, and 86 (26%) support staff. One hundred and forty-four (44%) had a GHQ-12 score > 12. The most common concerns reported included fear of infection at the workplace (81%), stigma from colleagues (79%), lack of workplace support (63%), and inadequate availability of personal protective equipment (PPE) (56%). In multivariable analysis, moderate (adjusted prevalence ratio, [aPR] = 2.2, 95% confidence interval [CI] 1.2-4.0) and high (aPR = 3.8, 95% CI 2.0-7.0) risk perception towards COVID-19 (compared with low-risk perception) were associated with psychological distress. CONCLUSIONS: Forty-four percent of HCWs surveyed in hospitals treating COVID-19 patients during the early COVID-19 epidemic in Uganda reported psychological distress related to fear of infection, stigma, and inadequate PPE. Higher perceived personal risk towards COVID-19 was associated with increased psychological distress. To optimize patient care during the pandemic and future outbreaks, workplace management may consider identifying and addressing HCW concerns, ensuring sufficient PPE and training, and reducing infection-associated stigma.

The burden of drug resistant tuberculosis in a predominantly nomadic population in Uganda: a mixed methods study.

BACKGROUND: Emergence of drug resistant tuberculosis (DR-TB) has aggravated the tuberculosis (TB) public health burden worldwide and especially in low income settings. We present findings from a predominantly nomadic population in Karamoja, Uganda with a high-TB burden (3500 new cases annually) and sought to determine the prevalence, patterns, factors associated with DR-TB. METHODS: We used mixed methods of data collection. We enrolled 6890 participants who were treated for tuberculosis in a programmatic setting between January 2015 and April 2018. A cross sectional study and a matched case control study with conditional logistic regression and robust standard errors respectively were used to the determine prevalence and factors associated with DR-TB. The qualitative methods included focus group discussions, in-depth interviews and key informant interviews. RESULTS: The overall prevalence of DR-TB was 41/6890 (0.6%) with 4/64,197 (0.1%) among the new and 37/2693 (1.4%) among the previously treated TB patients respectively. The drug resistance patterns observed in the region were mainly rifampicin mono resistant (68.3%) and Multi Drug-Resistant Tuberculosis (31.7%). Factors independently associated with DR-TB were previous TB treatment, adjusted odds ratio (aOR) 13.070 (95%CI 1.552-110.135) and drug stock-outs aOR 0.027 (95%CI 0.002-0.364). The nomadic lifestyle, substance use, congested homesteads and poor health worker attitudes were a great challenge to effective treatment of TB. CONCLUSION: Despite having the highest national TB incidence, Karamoja still has a low DR-TB prevalence. Previous TB treatment and drug stock outs were associated with DR-TB. Regular supply of anti TB medications and health education may help to stem the burden of TB disease in this nomadic population.

Violence and discrimination among Ugandan residents during the COVID-19 lockdown.

BACKGROUND: In March 2020, the World Health Organization (WHO) declared COVID-19 a pandemic. Many countries in Sub-Saharan Africa, Uganda inclusive, implemented lockdowns, curfew, banning of both private and public transport systems, and mass gatherings to minimize spread. Social control measures for COVID-19 are reported to increase violence and discrimination globally, including in Uganda as some may be difficult to implement resulting in the heavy deployment of law enforcement. Media reports indicated that cases of violence and discrimination had increased in Uganda's communities following the lockdown. We estimated the incidence and factors associated with experiencing violence and discrimination among Ugandans during the COVID-19 lockdown to inform control and prevention measures. METHODS: In April 2020, we conducted a secondary analysis of cross-sectional data under the International Citizen Project (ICP) to assess adherence to public health measures and their impact on the COVID-19 outbreak in Uganda. We analyzed data on violence and discrimination from the ICP study. We performed descriptive statistics for all the participants' characteristics and created a binary outcome variable called experiencing violence and/or discrimination. We performed logistic regression analysis to identify the factors associated with experiencing violence and discrimination. RESULTS: Of the 1726 ICP study participants, 1051 (58.8%) were males, 841 (48.7%) were currently living with a spouse or partner, and 376 (21.8%) had physically attended work for more than 3 days in the past week. Overall, 145 (8.4%) experienced any form of violence and/or discrimination by any perpetrator, and 46 (31.7%) of the 145 reported that it was perpetrated by a law enforcement officer. Factors associated with experiencing violence or discrimination were: being male (AOR = 1.60 CI:1.10-2.33), having attended work physically for more than 3 days in the past week (AOR = 1.52 CI:1.03-2.23), and inability to access social or essential health services since the epidemic started (AOR = 3.10 CI:2.14-4.50). CONCLUSION: A substantial proportion of Ugandan residents experienced violence and/or discrimination during the COVID-19 lockdown, mostly perpetrated by law enforcement officers. We recommend mitigation of the collateral impact of lockdowns with interventions that focus on improving policing quality, ensuring continuity of essential services, and strengthening support systems for vulnerable groups including males.

Level and Determinants of Adherence to COVID-19 Preventive Measures in the First Stage of the Outbreak in Uganda.

We conducted an online survey in the first two months of the Coronavirus Disease 2019 (COVID-19) epidemic in Uganda to assess the level and determinants of adherence to and satisfaction with the COVID-19 preventive measures recommended by the government. We generated Likert scales for adherence and satisfaction outcome variables and measured them with four preventive measures, including handwashing, wearing face masks, physical distancing, and coughing/sneezing hygiene. Of 1726 respondents (mean age: 36 years; range: 12-72), 59% were males, 495 (29%) were adherent to, and 545 (32%) were extremely satisfied with all four preventive measures. Adherence to all four measures was associated with living in Kampala City Centre (AOR: 1.7, 95% CI: 1.1-2.6) and receiving COVID-19 information from health workers (AOR: 1.2, 95% CI: 1.01-1.5) or village leaders (AOR: 1.4, 95% CI: 1.02-1.9). Persons who lived with younger siblings had reduced odds of adherence to all four measures (AOR: 0.75, 95% CI: 0.61-0.93). Extreme satisfaction with all four measures was associated with being female (AOR: 1.3, 95% CI: 1.1-1.6) and health worker (AOR: 1.2, 95% CI: 1.0-1.5). Experiencing violence at home (AOR: 0.25, 95% CI: 0.09-0.67) was associated with lower satisfaction. Following reported poor adherence and satisfaction with preventive measures, behavior change programs using health workers should be expanded throughout, with emphasis on men.
