Therefore, similar published analyses across cohorts are inconsistent. In our sample of women living with HIV (WLWH) and women without HIV (WWOH), we conducted comparable analyses as those published in men with and without HIV. We examined cross-sectional and longitudinal associations between body mass index (BMI) and waist circumference (WC) and NP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Four hundred thirty two 432 virologically-suppressed WLWH and 367 WWOH, \u226540 years in the Women\u2019s Interagency HIV Study (WIHS) with anthropometry and NP assessments every two years from 2009-2019 were included in the study. Demographically-adjusted T-scores were calculated for six NP domains: learning, memory, executive function, processing speed, attention and working memory, and motor function. Multivariable linear regression models stratified by HIV status were used to examine cross-sectional associations of BMI and WC by NP domain; repeated measures analyses assessed baseline BMI and WC in association with longitudinal change in NP. Covariates included sociodemographic, behavioral, and HIV-related characteristics.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At baseline among all women, the median age was 45 years, 65% were Non-Latinx Black women, and 45% were obese women. Obese WLWH (BMI\u226530.0 kg\/m<jats:sup>2<\/jats:sup>) had poorer executive function (\u03b2=-2.27, 95%CI [-4.46, -0.07]) versus WLWH with healthy BMI (18.5\u201324.9 kg\/m<jats:sup>2<\/jats:sup>). Longitudinally over ~8 years, obese versus overweight WWOH improved on memory (\u03b2=2.19, 95%CI [0.13, 4.26]), however overweight versus healthy WWOH experienced declining memory (\u03b2= -2.67, 95%CI [-5.40, -0.07]). Increasing WC was associated with declining executive, processing speed, and motor function (p\u2019s&amp;lt;0.05); an at-risk WC was associated with improved memory (\u03b2=1.81, 95%CI [0.19, 3.44]) among WWOH.
