Gender Gap Widens in HIV Life Expectancy: Women Face Significant Disparities Despite Overall Improvements
Key Insights
A British Columbia study reveals that despite overall improvements in HIV (search) life expectancy from 1996-2020, women consistently lag behind men, with the gender gap increasing to 7.05 years by 2020.
Women with HIV (search) showed higher mortality risks across multiple health conditions, with an adjusted hazard ratio of 1.37 for all-cause mortality compared to men.
Life expectancy for HIV (search)-positive men increased by 23.54 years versus 18.81 years for women over the study period, highlighting urgent needs for targeted interventions for women with HIV.
A comprehensive population-based cohort study conducted in British Columbia, Canada, has unveiled concerning gender disparities in life expectancy among people living with HIV (search), despite significant overall improvements in survival rates between 1996 and 2020.
The research, published in Lancet Public Health (search), analyzed data from 14,272 individuals, with women comprising 17.8% of the study population. The findings reveal a persistent and widening gap in life expectancy between men and women living with HIV (search), challenging assumptions about equal healthcare outcomes.
Widening Gender Disparities
By 2020, the life expectancy gap between men and women at age 20 had expanded to 7.05 years (95% CI, 3.10-11.0), a significant increase from 2.33 years in the 1996-2001 period. Men's life expectancy at age 20 improved from 24.46 years to 48.00 years, while women's increased from 22.13 years to 40.94 years during the study period.
Mortality Risk Factors
The study identified several concerning trends for women living with HIV (search):
- Women faced a 37% higher risk of all-cause mortality (adjusted HR, 1.37; 95% CI, 1.27-1.48)
- Non-communicable diseases showed a 33% higher mortality risk in women (adjusted HR, 1.33; 95% CI, 1.14-1.54)
- Particularly high risk was observed for renal disease, liver disease, and chronic respiratory disease (adjusted HR, 2.30; 95% CI, 1.66-3.21)
Socioeconomic Factors
The research highlighted significant socioeconomic disparities between genders:
- 43.5% of women reported injection drug use as an HIV transmission risk factor, compared to 26.0% of men
- 38.6% of women lived in the lowest income quintile, versus 30.9% of men
- Women were generally younger at baseline, with a median age of 34 years compared to 38 years for men
Clinical Implications
Dr. Katherine Kooij, study co-author, emphasizes the urgent need for targeted interventions: "These findings demonstrate the need for the provincial government, health care providers, and other HIV (search)-related organizations to urgently prioritize their focus on women who are living with, or who are at risk of contracting, HIV."
The study underscores the importance of developing public health initiatives that address systemic challenges facing women affected by HIV (search), including enhanced screening and preventative measures for non-communicable diseases.
Study Limitations
The researchers acknowledge several limitations, including:
- Potential generalizability issues for undiagnosed HIV cases
- Lack of data on gender roles and identity
- Limited individual-level information due to administrative data usage
- Missing values in HIV risk transmission categories
Despite free and accessible antiretroviral therapy (search), these findings highlight the complex interplay between gender, social determinants of health, and HIV (search) outcomes, calling for immediate action to address these persistent disparities in healthcare delivery and outcomes.
