Summary
This summary is machine-generated.Willingness to pay for long-acting injectable cabotegravir (CAB-LA) among men who have sex with men in China is low, with price elasticity of demand being elastic. Policy considerations include patent waivers and enhanced health education for CAB-LA promotion.
Area Of Science
- Public Health
- Health Economics
- Infectious Disease Prevention
Background
- Long-acting injectable cabotegravir (CAB-LA) became available in the US in 2021 for HIV prevention.
- No prior studies have investigated willingness to pay (WTP) for CAB-LA post-market introduction.
- Understanding WTP and price elasticity of demand (PED) is crucial for accessibility and public health strategies.
Purpose Of The Study
- To explore the willingness to pay for CAB-LA among men who have sex with men (MSM) in Guangxi, China.
- To identify factors associated with WTP for CAB-LA.
- To determine the price elasticity of demand (PED) for CAB-LA in this population.
Main Methods
- A cross-sectional study involving 1,006 MSM in Guangxi, China.
- Univariate and multivariate ordinal logistic regression analyses were used to identify factors associated with WTP.
- PED was calculated to assess the responsiveness of demand to price changes.
Main Results
- The median monthly WTP for CAB-LA was 200 Chinese Yuan (CNY), with 84.2% willing to pay less than 600 CNY.
- WTP was positively associated with younger age, higher education, higher monthly income, bisexual/unsure sexual orientation, and prior PrEP awareness/use.
- CAB-LA exhibited relatively elastic PED, with demand increasing significantly as price decreased across tested price points (e.g., PED of 3.13 when price dropped from 600 to 500 CNY).
Conclusions
- Willingness to pay for CAB-LA in Guangxi, China, is relatively low.
- The price elasticity of demand for CAB-LA is considerable, suggesting price sensitivity.
- Recommendations include considering waived patent protection for wider promotion and strengthening health education to improve CAB-LA recognition and uptake.
