Global, regional, and national sex-specific burden and control of the HIV epidemic, 1990-2019, for 204 countries and territories: the Global Burden of Diseases Study 2019

Background: The sustainable development goals (SDGs) aim to end HIV/AIDS as a public health threat by 2030. Understanding the current state of the HIV epidemic and its change over time is essential to this effort. This study assesses the current sex-specific HIV burden in 204 countries and territories and measures progress in the control of the epidemic. Methods: To estimate age-specific and sex-specific trends in 48 of 204 countries, we extended the Estimation and Projection Package Age-Sex Model to also implement the spectrum paediatric model. We used this model in cases where age and sex specific HIV-seroprevalence surveys and antenatal care-clinic sentinel surveillance data were available. For the remaining 156 of 204 locations, we developed a cohort-incidence bias adjustment to derive incidence as a function of cause-of-death data from vital registration systems. The incidence was input to a custom Spectrum model. To assess progress, we measured the percentage change in incident cases and deaths between 2010 and 2019 (threshold >75% decline), the ratio of incident cases to number of people living with HIV (incidence-to-prevalence ratio threshold <0·03), and the ratio of incident cases to deaths (incidence-to-mortality ratio threshold <1·0). Findings: In 2019, there were 36·8 million (95% uncertainty interval [UI] 35·1–38·9) people living with HIV worldwide. There were 0·84 males (95% UI 0·78–0·91) per female living with HIV in 2019, 0·99 male infections (0·91–1·10) for every female infection, and 1·02 male deaths (0·95–1·10) per female death. Global progress in incident cases and deaths between 2010 and 2019 was driven by sub-Saharan Africa (with a 28·52% decrease in incident cases, 95% UI 19·58–35·43, and a 39·66% decrease in deaths, 36·49–42·36). Elsewhere, the incidence remained stable or increased, whereas deaths generally decreased. In 2019, the global incidence-to-prevalence ratio was 0·05 (95% UI 0·05–0·06) and the global incidence-to-mortality ratio was 1·94 (1·76–2·12). No regions met suggested thresholds for progress. Interpretation: Sub-Saharan Africa had both the highest HIV burden and the greatest progress between 1990 and 2019. The number of incident cases and deaths in males and females approached parity in 2019, although there remained more females with HIV than males with HIV. Globally, the HIV epidemic is far from the UNAIDS benchmarks on progress metrics.

Measuring routine childhood vaccination coverage in 204 countries and territories, 1980-2019 : a systematic analysis for the Global Burden of Disease Study 2020, Release 1

Background Measuring routine childhood vaccination is crucial to inform global vaccine policies and programme implementation, and to track progress towards targets set by the Global Vaccine Action Plan (GVAP) and Immunization Agenda 2030. Robust estimates of routine vaccine coverage are needed to identify past successes and persistent vulnerabilities. Drawing from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020, Release 1, we did a systematic analysis of global, regional, and national vaccine coverage trends using a statistical framework, by vaccine and over time. Methods For this analysis we collated 55 326 country-specific, cohort-specific, year-specific, vaccine-specific, and dosespecific observations of routine childhood vaccination coverage between 1980 and 2019. Using spatiotemporal Gaussian process regression, we produced location-specific and year-specific estimates of 11 routine childhood vaccine coverage indicators for 204 countries and territories from 1980 to 2019, adjusting for biases in countryreported data and reflecting reported stockouts and supply disruptions. We analysed global and regional trends in coverage and numbers of zero-dose children (defined as those who never received a diphtheria-tetanus-pertussis [DTP] vaccine dose), progress towards GVAP targets, and the relationship between vaccine coverage and sociodemographic development. Findings By 2019, global coverage of third-dose DTP (DTP3; 81.6% [95% uncertainty interval 80.4-82 .7]) more than doubled from levels estimated in 1980 (39.9% [37.5-42.1]), as did global coverage of the first-dose measles-containing vaccine (MCV1; from 38.5% [35.4-41.3] in 1980 to 83.6% [82.3-84.8] in 2019). Third- dose polio vaccine (Pol3) coverage also increased, from 42.6% (41.4-44.1) in 1980 to 79.8% (78.4-81.1) in 2019, and global coverage of newer vaccines increased rapidly between 2000 and 2019. The global number of zero-dose children fell by nearly 75% between 1980 and 2019, from 56.8 million (52.6-60. 9) to 14.5 million (13.4-15.9). However, over the past decade, global vaccine coverage broadly plateaued; 94 countries and territories recorded decreasing DTP3 coverage since 2010. Only 11 countries and territories were estimated to have reached the national GVAP target of at least 90% coverage for all assessed vaccines in 2019. Interpretation After achieving large gains in childhood vaccine coverage worldwide, in much of the world this progress was stalled or reversed from 2010 to 2019. These findings underscore the importance of revisiting routine immunisation strategies and programmatic approaches, recentring service delivery around equity and underserved populations. Strengthening vaccine data and monitoring systems is crucial to these pursuits, now and through to 2030, to ensure that all children have access to, and can benefit from, lifesaving vaccines.

Magnitude of Gender-Based Violence and Its Associated Factors among Female Night Students in Bahir Dar City, Amhara Region, Ethiopia

Background. Gender-based violence (GBV) is a major public health issue that affects the health and well-being of millions of young people worldwide each year. Gender-based violence was prevalent throughout Sub-Saharan Africa. However, research in Africa is extremely diverse. Objective. The purpose of this study is to determine the extent and risk factors of gender-based violence among night female students in Bahir Dar, Ethiopia. Methods. This cross-sectional study was conducted among 788 elementary and high school night female students in Bahir Dar from October 15 to November 15, 2019. Data was gathered using self-administered questionnaires. A binary and multiple logistic regression model was used to identify factors associated with gender-based and sexual violence. An adjusted odds ratio (AOR) with a 95 percent confidence interval (CI) was calculated to determine the level of significance. Results. The overall lifetime prevalence of gender-based violence (sexual, physical, and emotional violence) was 71.1% with a 95% CI of 67.8%-74.1%. The lifetime prevalence of sexual violence, physical violence, and emotional violence was 49.1%, 57.5%, and 41.6%, respectively. Rural childhood residence (AOR: 3.37, 95% CI: (2.17-5.54)), low school performance (AOR: 3.44, 95% CI: (2.13-5.56)), lack of sexual and reproductive health conversation experience (AOR: 3.68, 95% CI: (2.07-6.54)), poor family control (AOR: 5.62, 95% CI: (3.25-9.71)), and being sexually active (AOR: 3.79, 95% CI: (2.35-6.12)) increased significantly the risk of gender-based violence. The risk factors for sexual violence were young people living with both parents (AOR: 0.28, 95% CI: (0.19-0.41)), peer pressure (AOR: 5.73, 95% CI: (4.11-7.98)), and family support (AOR: 0.31, 95% CI: (0.22-0.43)). Conclusion. In the study area, the lifetime prevalence of sexual violence, physical violence, and emotional violence was high. As a result, it is recommended that policymakers, district officials, schools, and other stakeholders pay attention to and act on gender-based values

Sexual and reproductive health issues and associated factors among female night school students in Amhara Region, Ethiopia: an institution-based cross-sectional study

Objective This study aimed to assess the prevalence of sexual and reproductive health (SRH) issues and associated factors among female night school students in the Amhara Region, Ethiopia.Design Institution-based cross-sectional study.Setting 16 night schools were selected from 4 zones in the Amhara Region. The data were collected between 1 January and 28 February 2019.Participants 1428 female night school students aged 15–24 years.Outcomes Prevalence of SRH issues, defined as those who had experienced at least one SRH issue during their lifetime (including sexual violence, sexually transmitted diseases, teenage pregnancy, unwanted pregnancy, early marriage and abortion). Bivariable and multivariable logistic regression models were used in the analysis.Results The prevalence of SRH issues was 32.7% (95% CI 29.5% to 35.9%). Having secondary education (adjusted (OR) AOR = 1.49, 95% CI 1.19 to 1.86), being single in marital status (AOR = 1.33, 95% CI 1.01 to 1.74), not discussing SRH issues with their families (AOR = 2.69, 95% CI 2.13 to 3.40) and poor knowledge of SRH services (AOR = 2.63, 95% CI 2.08 to 3.32) were significantly associated with SRH issues.Conclusion The lifetime prevalence of SRH issues among female night school students was high. Being single, having a secondary education, not discussing SRH issues with family, and having a poor understanding of SRH services were associated with SRH issues. Qualitative studies should be conducted to explore students’ feelings and intentions about SRH issues
