Trends and disparities in deaths among young persons in the US during the COVID-19 pandemic

PURPOSE

To examine changes in death rates by demographic group and by the leading causes of death in U.S. persons 1 to 24 years of age during the COVID-19 pandemic.

METHODS

A retrospective cross-sectional study using mortality data from the National Vital Statistics System from April 2017 to March 2023. Pre-pandemic death rates were compared with death rates during the pandemic overall, by race/ethnicity, age, sex, and cause group.

RESULTS

Age-adjusted death rates in young persons 1-24 years of age increased by 14.3% during the pandemic. Injury-related causes accounted for 78.2% of the increase, driven mainly by increases in homicides and unintentional injuries related to drug overdose, firearms, and motor-vehicle traffic crashes. Non-Hispanic Black and Hispanic teens and young adults experienced the largest increases in deaths overall and across the leading causes of death.

CONCLUSIONS

During the COVID-19 pandemic, injury-related causes accounted for the majority of the increases in deaths in children and young adults, driven mainly by firearms, drug overdoses, and motor vehicle traffic crashes. Findings highlight the importance of understanding the drivers of these marked increases in injury-related mortality and the need for injury prevention efforts among children even in the context of an infectious disease pandemic.

Global health surveillance

Awareness of the importance of global health surveillance increased in the latter part of the 20th century with the global emergence of human immunodeficiency virus and novel strains of influenza. In the first decade of the 21st century, several events further highlighted global shared interests in and vulnerability to infectious diseases. Bioterrorist use of anthrax spores in 2001 raised awareness of the value of public health surveillance for national security. The epidemic of severe acute respiratory syndrome (SARS) in 2003, re-emergence of a panzootic of avian influenza A H5N1 in 2005, and the sudden emergence of pandemic H1N1 in North America in 2009 all highlighted the importance of shared global responsibility for surveillance and disease control. In particular, in 2003, SARS precipitated changes in awareness of the world's collective economic vulnerability to epidemic shocks.

Factors associated with HIV infection in adolescent females in Zimbabwe

PURPOSE

To identify factors associated with human immunodeficiency virus (HIV) infection among adolescent females in Zimbabwe and appropriate prevention strategies for this vulnerable population.

METHODS

A total of 1807 females aged 15-19 years completed a questionnaire and provided a blood sample for HIV testing as part of a nationally representative survey. Associations between HIV infection and factors operating at the individual, household, partner and community levels, as well as sexual behavior, were explored through bivariate and multivariate logistic regression analyses. Two multivariate models were fitted: the first model considered sexual risk behaviors and contextual variables, whereas the second model considered only contextual variables.

RESULTS

Of 1807 adolescent females, 192 (10.6%) were HIV positive, and 41% of HIV-positive adolescent females reported no sexual risk behaviors. In the first multivariate model, the risk associated with number of lifetime sexual partners was increased for 1 partner (odds ratio [OR] = 2.4, 95% confidence interval [CI] = 1.57-3.6), 2 partners (OR = 4.4, 95% CI = 2.22-8.55), and 3 or more partners (OR = 6.3, 95% CI = 2.56-15.7) as compared with having 0 partners. Believing that people with HIV have many sexual partners (OR = 1.71, 95% CI = 1.14-2.57) and that the man should take the initiative to have sex (OR = 1.55, 95% CI = 1.03-2.32) were also risk factors. In the second model, increased risk was associated with having ever married or lived with a man (OR = 1.99, 95% CI = 1.18-3.35) as well as the attitudes above. Decreased risk of HIV infection was associated with having a job (OR = .39, 95% CI = .18-.88), main activity in past 12 months was as a student (OR = .39, 95% CI = .19-.80), participation in school-based lectures on sexual health (OR = .49, 95% CI = .27-.87), and perceiving that AIDS is a somewhat serious problem in the community (OR = .55, 95% CI = .33-.92).

CONCLUSIONS

Adolescent females in Zimbabwe who are married, not attending school and/or are unemployed, are at heightened risk for HIV infection. Interventions that improve their educational and employment opportunities, strengthen school-based prevention services, foster more equitable gender attitudes, and make marriage safer by, for example, promoting knowledge of partners' serostatus before marriage, may reduce their risk. Future research priorities are proposed.
