BACKGROUND:
: HIV remains a major global health issue, especially in sub-Saharan Africa. Knowing one's status is crucial for combating HIV/AIDS and achieving the 2030 SDGs. However, testing coverage among young people in Tanzania remains low. This study aimed to identify factors influencing HIV testing among young Tanzanian women using Anderson’s Behavioral Model.

METHODS:
We analyzed a weighted sample of 5,810 young women from the 2022 Tanzania DHS. A multilevel mixed-effect logistic regression model was used to identify factors associated with 'ever tested for HIV.' Adjusted Odds Ratios (AORs) with 95% Confidence Intervals (CIs) were calculated. Statistical significance was determined at a p-value of less than 0.05.

RESULTS:
In our study, the prevalence of HIV testing among young women was 60.18% (95% CI: 58.91% to 61.43%). Significant factors associated with HIV testing included age (AOR = 4.33, 95% CI [3.43, 5.45]), marital status (AOR = 2.31, 95% CI [1.76, 3.04]), knowledge of HIV prevention (AOR = 1.59, 95% CI [1.23, 2.04]), discriminatory attitudes towards HIV (AOR = 0.74, 95% CI [0.58, 0.95]), visiting healthcare facilities (AOR = 4.80, 95% CI [3.75, 6.14]), media exposure (AOR = 1.44, 95% CI [1.09, 1.90]), internet use (AOR = 1.56, 95% CI [1.02, 2.38]), and ever heard of STIs (AOR = 2.12, 95% CI [1.63, 2.77]). Conclusion and Recommendation: Our study found that six in ten young Tanzanian women have been tested for HIV. Addressing barriers like stigma and improving access to healthcare and information through media and the internet can significantly boost HIV testing rates among young women, aiding the global effort to end the AIDS epidemic by 2030.
