1. Improve definitions and descriptions of terminology such as low socioeconomic status, diversity & disparities on regional, national and global levels
2. Advance identification & characterization of populations at risk and
actively recognize & use these characteristics in study design, data interpretation and designing interventions
3. Broaden measurement & detection environments through active & integrated partnerships comprised of industry, healthcare, public health, government & academic entities
What are some ‘translational’ needs across diverse,
aging HIV communities?

ADA and FINRISC Diabetes Risk Scores
• Risk scores include:• Age
• BMI (weight [kg]/height2 [meters])
• waist circumference
• history of hypertension (systolic blood pressure ≥140 mmHg and diastolic blood pressure ≥90 mmHg or self-reported hypertension or as self-reported anti-hypertension medication use prior to or at index visit)
• history of hyperglycemia (FBG measure of 100–125 mg/dL at index visit)
• family history of diabetes.
• Physical activity was excluded from the ADA model
• FINRISC concise model, excludes physical activity and fruit and vegetable consumption

Use of Diabetes Risk Scores in the WIHS:ADA and FINRISC
• 1111 HIV+ (median age 41) and 454 HIV- women (median age 38)
• ADA sensitivity did not differ: HIV+ (77%), HIV- women (81%)• Specificity better in HIV- women (42% vs. 49%, p=0.006).
• Overall ADA discrimination suboptimal in both HIV+ (AUROC=0.64 [95% CI: 0.58, 0.70]) and HIV- women (AUROC=0.67 [95% CI: 0.57, 0.77]).
• FINRISC sensitivity and specificity did not differ: HIV+ (72% and 49%, respectively), HIV- women (86% and 52%, respectively). • Overall FINRISC discrimination was suboptimal in HIV+ (AUROC=0.68 [95%
CI: 0.62, 0.75]) and HIV- women (AUROC=0.78 [95% CI: 0.66, 0.90]).
• Greater misclassification was generally observed among HIV+ women.

HIV–Diabetes Care Continuum Over 15 Years
• HIV-specific risk factors known to contribute to diabetes risk
should be explored in these models.
• Gains in life expectancy through optimal control of HIV
infection with antiretroviral therapy (ART) may be threatened
if other comorbidities, such as diabetes, are not optimally
managed.

• Proportions of HIV+ and HIV- women with diabetes who were
engaged in care and achieved treatment goals, ABCs:
• Hemoglobin A1c [A1c] <7.0%
• Blood pressure [BP] <140/90 mmHg
• LDL cholesterol <100 mg/dL
• No smoking
• 486 HIV-positive and 258 HIV-negative women with diabetes
• Cross-sectional WIHS data from 2001, 2006, and 2015.

HIV–Diabetes Care Continuum Over 15 Years
• In 2001, 91.8% visited a health care provider
• 60.7% achieved the HbA1c target
• 70.5% achieved the BP target
• 38.5% achieved the LDL cholesterol target
• 49.2% were nonsmokers
• 23.3% achieved combined ABC targets (A1c, BP, and cholesterol)
• 10.9% met combined ABC targets and did not smoke
• No differences by HIV status
• Patterns similar in 2006 and 2015.
• Viral suppression increased from 41% in 2001 to 87% in 2015 in WWH
• Viral suppression not associated with achievement of diabetes care goals

HIV–Diabetes Care Continuum Over 15 Years
• Successful management of HIV is outpacing that of diabetes.
• Future studies are needed to identify factors associated with gaps in the HIV–diabetes care continuum and design interventions to better integrate effective diabetes management into HIV care.
• Findings reinforce the importance of considering HIV a chronic infectious disease, for which the aggressive management of comorbid cardio-renal risk factors, such as diabetes, is important.

• Integrase strand-transfer inhibitor (INSTI)-based ART, for example, is associated with severe body weight gain.
• WWH who switched to an INSTI-based ART or added it to their ongoing regimen experienced, within 2 years, an average increase of • 2.1 kg in body weight
• 0.8 kg/m² in BMI
• 1.4% in percent body fat
• 2.0, 1.9, 0.6, and 1.0cm in waist, hip, arm, and thigh circumferences, respectively (all p <0.05).
• There were no differences in magnitude of these changes by INSTI type.

Cross-Sectional Adiposity Conclusions
• Adipokines measures may provide mechanistic insights of fat-brain or gut-brain associations in middle-aged HIV+ and at risk HIV- women.

Longitudinal Adiposity ConclusionsBody mass index and leptin are associated with executive function over 10
years in women with and without HIV infection
• 301 HIV+ and 113 HIV- WIHS participants
• Over 10 years
• HIV+ and HIV- women transitioned from overweight (29.1+/-7.9 kg/m2) to obese (30.4+/-7.9 kg/m2).
• Leptin increased (11.4+/-26.4 ng/ml).
• Higher baseline BMI and leptin predicted lower EF 10 years later in HIV- women (BMI b=-0.368,
SE=0.099, p<0.001; leptin b = -0.134 SE=0.038, p=0.001).
• Among HIV+ women, 10y increases in BMI and leptin predicted lower EF score (BMI b= -0.383, SE=0.16,
p=0.019; leptin b= -0.071, SE=0.025, p=0.006) adjusted for HIV viral load and CD4+.

Bone Health in a DXA substudy
• Among WWH (average obese and adherent to ART), older age, White (vs. Black) race, prior fracture, history of cocaine use, and history of injection drug use were significant predictors of incident fracture, a marker of low bone mineral density, over 10 years follow-up.
• Evaluation over 5.4 years during premenopause only, there was no association of HIV status with fracture risk• Traditional risk factors such as White (vs. Black) race, hepatitis C virus infection,
and higher serum creatinine were associated with fracture

• Cross-sectionally, when compared to uninfected women, after adjusting for age, race, menopause status, and BMI, WWH have:• degraded skeletal microarchitecture (27% vs. 9%, P=0.001)
• lower mean lumbar spine (LS) & trabecular bone score (TBS) • 1.3 ± 0.1 vs. 1.4 ± 0.1, P< 0.001
• No differences between WWH and uninfected women in:• correlations between annual changes in
• TBS and BMD
• LS and BMD
• mean % annual change in TBS • -1.0%/yr ± 2.9% for WWH
• -0.8%/yr ± 1.7% for uninfected women

Falls and Frailty
• Falls associated with the Fried Frailty Phenotype (FFP) in WWH
• FFP predicts almost 2-fold higher odds of recurrent falls (not single falls) among middle-aged WWH.
• Unintentional weight loss and exhaustion most informative.
• Multi-faceted bone health and frailty risk profile in, on average, obese WWH.

Self-Reported Successful Aging

Better SRSA
Score
No differences in SRSA prevalence by HIV status:
• 84% of older (50+) WWH and 83% of HIV- women report an SRSA ≥7 (range = 2-10)
• SRSA ≥7 associated with higher levels of positive psychosocial characteristics • e.g., resilience and optimism, in older WWH and HIV- women.
