Yaguang Zheng is an assistant professor at NYU Rory Meyers College of Nursing. Her research focuses on cardiometabolic risk reduction by leveraging mobile health, electronic health records, and data science techniques. Zheng has explored behavioral phenotypes through the use of wireless devices in clinical trials and real-world settings and their impacts on cardiometabolic disease prevention and management. Zheng’s initial work focused on lifestyle behavior changes through mobile health, more specifically, using mobile health for self-monitoring and its impact on weight-loss outcomes. After identifying a critical knowledge gap in the area of engagement with mobile health, Zheng conducted a pilot study that found that older adults were able to use multiple mobile devices to improve diabetes self-management, debunking traditional perceptions of older adults as being skeptical of multiple mobile technologies.
Zheng has also applied machine learning algorithms to analyze data from a large real-world sample that has yielded varied patterns of use of wireless devices over the course of a year, findings which are helping to target subgroups of individuals who need long-term engagement in using mobile health devices. More recently, Zheng has worked on electronic health record data, including mobile health data from wearable devices, like continuous glucose monitors, which has real-world application for clinical practice.
Prior to joining the NYU Rory Meyers faculty, Zheng was a postdoctoral scholar supported by NIH grant T32 NR008857 Technology: Research in Chronic and Critical Illness at the University of Pittsburgh School of Nursing.
Zheng earned her PhD at the University of Pittsburgh. She also received a Nursing Informatics Certificate during her postdoctoral training.

Racial and ethnic disparities in the burden of non-obese type 2 diabetes using different anthropometric measurements
AbstractSui, J., Wu, B., Zheng, Y., Mo, Z., Dong, Q., Ðoàn, L. N., Yi, S. S., & Qi, X. (2025). Obesity Medicine, 53. 10.1016/j.obmed.2024.100573AbstractAIMS: Compare racial/ethnic disparities in the prevalence of non-obese type 2 diabetes (T2D) and the proportion of non-obese individuals among T2D patients.METHODS: This cross-sectional study used ICD-9/10 codes to ascertain T2D. Participants were classified as non-obese by BMI (<25 kg/m2 for normal weight; <23 kg/m2 for Asian Americans), waist circumference (<102 cm for males, <88 cm for females), and waist-to-hip ratio (<0.9 for males, <0.85 for females). The statistical analysis used marginal standardization of predicted probabilities from multivariable logistic regression to calculate the prevalence.KEY RESULTS: Among 276,736 participants (mean age 51.7, 61.2% female), non-obese T2D prevalence varied: 6.85% (BMI), 4.17% (waist circumference), 3.63% (waist-to-hip ratio). Asian participants had the highest prevalence of normal-weight T2D (2.70% vs. 1.92% in White, OR 1.44, 95% CI: 1.22-1.69) and non-obese T2D by waist circumference (8.04% vs. 3.36%, OR 2.61, 95% CI: 2.35-2.89). Black participants had the highest prevalence using waist-to-hip ratio (5.37% vs. 2.91%, OR 1.91, 95% CI: 1.80-2.03).CONCLUSION: Asian Americans showed higher non-obese T2D prevalence by BMI and waist circumference, while Black adults had higher prevalence by waist-to-hip ratio, suggesting different fat distribution patterns.Association Between Video-Based Telemedicine Visits and Medication Adherence Among Patients With Heart Failure: Retrospective Cross-Sectional Study
AbstractZheng, Y., Adhikari, S., Li, X., Zhao, Y., Mukhopadhyay, A., Hamo, C. E., Stokes, T., & Blecker, S. (2024). JMIR Cardio, 8, e56763. 10.2196/56763AbstractBACKGROUND: Despite the exponential growth in telemedicine visits in clinical practice due to the COVID-19 pandemic, it remains unknown if telemedicine visits achieved similar adherence to prescribed medications as in-person office visits for patients with heart failure.OBJECTIVE: Our study examined the association between telemedicine visits (vs in-person visits) and medication adherence in patients with heart failure.METHODS: This was a retrospective cross-sectional study of adult patients with a diagnosis of heart failure or an ejection fraction of ≤40% using data between April 1 and October 1, 2020. This period was used because New York University approved telemedicine visits for both established and new patients by April 1, 2020. The time zero window was between April 1 and October 1, 2020, then each identified patient was monitored for up to 180 days. Medication adherence was measured by the mean proportion of days covered (PDC) within 180 days, and categorized as adherent if the PDC was ≥0.8. Patients were included in the telemedicine exposure group or in-person group if all encounters were video visits or in-person office visits, respectively. Poisson regression and logistic regression models were used for the analyses.RESULTS: A total of 9521 individuals were included in this analysis (telemedicine visits only: n=830 in-person office visits only: n=8691). Overall, the mean age was 76.7 (SD 12.4) years. Most of the patients were White (n=6996, 73.5%), followed by Black (n=1060, 11.1%) and Asian (n=290, 3%). Over half of the patients were male (n=5383, 56.5%) and over half were married or living with partners (n=4914, 51.6%). Most patients' health insurance was covered by Medicare (n=7163, 75.2%), followed by commercial insurance (n=1687, 17.7%) and Medicaid (n=639, 6.7%). Overall, the average PDC was 0.81 (SD 0.286) and 71.3% (6793/9521) of patients had a PDC≥0.8. There was no significant difference in mean PDC between the telemedicine and in-person office groups (mean 0.794, SD 0.294 vs mean 0.812, SD 0.285) with a rate ratio of 0.99 (95% CI 0.96-1.02; P=.09). Similarly, there was no significant difference in adherence rates between the telemedicine and in-person office groups (573/830, 69% vs 6220/8691, 71.6%), with an odds ratio of 0.94 (95% CI 0.81-1.11; P=.12). The conclusion remained the same after adjusting for covariates (eg, age, sex, race, marriage, language, and insurance).CONCLUSIONS: We found similar rates of medication adherence among patients with heart failure who were being seen via telemedicine or in-person visits. Our findings are important for clinical practice because we provide real-world evidence that telemedicine can be an approach for outpatient visits for patients with heart failure. As telemedicine is more convenient and avoids transportation issues, it may be an alternative way to maintain the same medication adherence as in-person visits for patients with heart failure.Association between visit frequency, continuity of care, and pharmacy fill adherence in heart failure patients
AbstractHamo, C. E., Mukhopadhyay, A., Li, X., Zheng, Y., Kronish, I. M., Chunara, R., Dodson, J., Adhikari, S., & Blecker, S. (2024). American Heart Journal, 273, 53-60. 10.1016/j.ahj.2024.04.003AbstractBackground: Despite advances in medical therapy for heart failure with reduced ejection fraction (HFrEF), major gaps in medication adherence to guideline-directed medical therapies (GDMT) remain. Greater continuity of care may impact medication adherence and reduced hospitalizations. Methods: We conducted a cross-sectional study of adults with a diagnosis of HF and EF ≤40% with ≥2 outpatient encounters between January 1, 2017 and January 10, 2021, prescribed ≥1 of the following GDMT: 1) Beta Blocker, 2) Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Blocker/Angiotensin Receptor Neprilysin Inhibitor, 3) Mineralocorticoid Receptor Antagonist, 4) Sodium Glucose Cotransporter-2 Inhibitor. Continuity of care was calculated using the Bice-Boxerman Continuity of Care Index (COC) and the Usual Provider of Care (UPC) index, categorized by quantile. The primary outcome was adherence to GDMT, defined as average proportion of days covered ≥80% over 1 year. Secondary outcomes included all-cause and HF hospitalization at 1-year. We performed multivariable logistic regression analyses adjusted for demographics, insurance status, comorbidity index, number of visits and neighborhood SES index. Results: Overall, 3,971 individuals were included (mean age 72 years (SD 14), 71% male, 66% White race). In adjusted analyses, compared to individuals in the highest COC quartile, individuals in the third COC quartile had higher odds of GDMT adherence (OR 1.26, 95% CI 1.03-1.53, P = .024). UPC tertile was not associated with adherence (all P > .05). Compared to the highest quantiles, the lowest UPC and COC quantiles had higher odds of all-cause (UPC: OR 1.53, 95%CI 1.23-1.91; COC: OR 2.54, 95%CI 1.94-3.34) and HF (UPC: OR 1.81, 95%CI 1.23-2.67; COC: OR 1.77, 95%CI 1.09-2.95) hospitalizations. Conclusions: Continuity of care was not associated with GDMT adherence among patients with HFrEF but lower continuity of care was associated with increased all-cause and HF-hospitalizations.Association of Gum Treatment with Cognitive Decline and Dementia Risk among Older Adults with Periodontal Symptoms: A 12-Year Prospective Cohort Study
AbstractQi, X., Zhu, Z., Wang, K., Zheng, Y., Li, A., & Wu, B. (2024). Neuroepidemiology, 1-10. 10.1159/000540086AbstractINTRODUCTION: This study examines the associations of gum treatment with cognitive decline and dementia risk among older adults with periodontal symptoms in the USA.METHODS: A cohort of 866 adults aged ≥50 with periodontal symptoms was recruited for the 2008 Health and Retirement Study "Dental Health Experimental Module" and followed until 2020. Cognitive function was assessed with the Telephone Interview for Cognitive Status (TICS). Dementia status was ascertained with the Langa-Weir algorithm based on TICS scores and proxy assessments. Linear mixed-effects model and multivariable Cox regression models were utilized to analyze the associations of gum treatment with cognitive decline and the risk of dementia, respectively.RESULTS: Of 866 participants (mean age 67.7, 61.4% women), 105 (12.1%) developed dementia with a median follow-up of 9 (IQR, 6-10) years. The dementia incidence rates were lower in the group with gum treatment (7.4 vs. 12.9 per 1,000 person-years). Compared with participants who did not have gum treatment, those with gum treatment experienced a decline in TICS score that was on average 0.025 (95% CI, 0.005-0.044) points less per year and a 38% lower incidence of dementia (hazard ratio, 0.62; 95% CI, 0.41-0.93). These associations were consistent across participants with a different severity of periodontal symptoms and sociodemographic characteristics (age, sex, race, ethnicity, and education) except for income levels.CONCLUSION: Prompt gum treatment for older adults with periodontal symptoms may be beneficial for their cognitive health.School-Based Protective Factors for HIV Prevention in the United States: Secondary Analysis of the Youth Risk Behavior Survey 2015-2019
AbstractGarcia, D. R., Fletcher, J., Goldsamt, L., Bell, D. L., Zheng, Y., & Dunn Navarra, A.-M. (2024). The Journal of the Association of Nurses in AIDS Care : JANAC. 10.1097/JNC.0000000000000501AbstractThis secondary analysis of the National Youth Risk Behavior Survey (years 2015-2019) examines associations between school-based protective factors (i.e., safe school environments and academic achievement) and HIV risk behaviors among sexually experienced adolescent gay and bisexual men ( n = 644), a population with the highest prevalence of undiagnosed HIV infections. Demographics included Hispanics/Latinos (25%, n = 158), Other race/ethnicity (14%, n = 88), and non-Hispanic Blacks/African Americans (13%, n = 81). Adjusted models showed that protective factors reduced odds for early sexual debut, multiple sexual partners, sex under the influence of drugs/alcohol, and condomless sex, with an additive effect demonstrated when two protective factors were present. Hispanics/Latinos had greater odds of reporting multiple sexual partners and HIV testing, indicating opportunities for school-based HIV prevention and further research. Our findings provide support for school-based programs that aim to improve social and structural determinants of health and ultimately reduce adolescent HIV burdens.Age differences in the effects of multi-component periodontal treatments on oral and metabolic health among people with diabetes mellitus: A meta-epidemiological study
AbstractZhu, Z., Qi, X., Zheng, Y., Pei, Y., & Wu, B. (2023). Journal of Dentistry, 135, 104594. 10.1016/j.jdent.2023.104594AbstractOBJECTIVE: To explore the age differences in the effects of multi-component periodontal treatments on oral and metabolic indicators among individuals with periodontitis and diabetes.DATA: Trials reporting the effects of multi-component periodontal treatments on oral and metabolic indicators among participants aged 18 and above with periodontitis and diabetes were included.SOURCES: Six databases (PubMed/Medline, Embase, CINHAL, Web of Science, Cochrane Library, and ProQuest) were searched from database inception to August 2022.STUDY SELECTION: Two reviewers selected the included studies independently. We used bivariate and multivariate meta-regression models to examine the association between age and treatment effect size. The primary outcomes were changes in probing depth (PD), clinical attachment level (CAL), and hemoglobin A1c (HbA1c).RESULTS: A total of 18,067 articles were identified in the database search. Of these, 115 trials (119 articles) met inclusion criteria. The mean age of participants was 58 years old, ranging from 35 to 73 years. The pooled evidence demonstrated that multi-component periodontal treatment significantly reduced PD (g=0.929 [0.689-1.169], I2=94.1%), CAL (g=0.879 [0.669-1.089], I2=92.1%), and HbA1c (g=0.603 [0.443-0.763], I2=87.5%). A significant decreasing trend was observed in the effect size for PD (P for trend = 0.020) and CAL (P for trend = 0.028) as age increases. Results from multivariate meta-regression showed that mean age was associated with a smaller effect size for PD (β=-0.123 [0.041], P = 0.004) and CAL (β=-0.159 [0.055], P = 0.006). Compared to their younger counterparts, the effect size for HbA1c was smaller among participants aged 55 and older (β=-0.792 [0.322], P = 0.017).CONCLUSIONS: Multi-component periodontal treatments may be more effective in younger populations in terms of effects on PD, CAL, and HbA1c.CLINICAL SIGNIFICANCE: Our study highlights the importance of early intervention and tailored treatment approaches. Clinicians should take into account the patient's age when developing periodontal treatment plans and may need to employ more aggressive or personalized strategies for older adults to achieve optimal outcomes.Association Between Types of Family Support and Glycemic Control for Adults With Cognitive Impairment
AbstractZheng, Y., Lawrence, K., Fletcher, J., Qi, X., & Wu, B. (2023). Gerontology and Geriatric Medicine, 9, 23337214231218800. 10.1177/23337214231218800AbstractBACKGROUND: Family support is important in assisting with diabetes self-management for individuals with cognitive impairment, but what types of family support are most effective remain unknown.OBJECTIVES: We aimed to examine the association between the types of family support in diabetes self-management with glycemic control in middle-aged and older adults with cognitive impairment.METHODS: A total of 267 individuals were included with diabetes and cognitive impairment (27-point Telephone Interview for Cognitive Status score <12), using the data of 2003 Health and Retirement Study (HRS) Diabetes Study and 2004 wave of the HRS.RESULTS: Most respondents were White (68.9%), followed by Black (25.8%). The mean age was 73.4±8.4 years. Adults with strong family support (as indicated by a "strongly agree" response) in testing sugar and in handling feelings about diabetes had significantly lower A1C compared with those with less family support (mean ± standard deviation: 7.08±1.39 vs. 7.51±1.42, P=.03; 6.79±0.87 vs. 7.57±1.53; P=.007 respectively).CONCLUSIONS: Our findings indicate that family members of individuals with cognitive impairment provide critical support to patients with diabetes and cognitive impairment, and may need additional intervention to assist with diabetes self-management tasks that require unique knowledge and skills.Dietary Self-Management Using Mobile Health Technology for Adults With Type 2 Diabetes: A Scoping Review
AbstractZheng, Y., Campbell Rice, B., Melkus, G. D., Sun, M., Zweig, S., Jia, W., Parekh, N., He, H., Zhang, Y. L., & Wylie-Rosett, J. (2023). Journal of Diabetes Science and Technology, 17(5), 1212-1225. 10.1177/19322968231174038AbstractObjective: Dietary self-management is one key component to achieve optimal glycemic control. Advances in mobile health (mHealth) technology have reduced the burden of diabetes self-management; however, limited evidence has been known regarding the status of the current body of research using mHealth technology for dietary management for adults with type 2 diabetes. Methods: Literature searches were conducted electronically using PubMed, CINAHL (EBSCO), Web of Science Core Collection, PsycINFO (Ovid), EMBASE (Ovid), and Scopus. Keywords and subject headings covered dietary management, type 2 diabetes, and mHealth. Inclusion criteria included studies that applied mHealth for dietary self-management for adults with type 2 diabetes and were published in English as full articles. Results: This review (N = 15 studies) revealed heterogeneity of the mHealth-based dietary self-management or interventions and reported results related to physiological, dietary behavioral, and psychosocial outcomes. Twelve studies applied smartphone apps with varied functions for dietary management or intervention, while three studies applied continuous glucose monitoring (CGM) to guide dietary changes. Among 15 reviewed studies, only three of them were two-arm randomized clinical trial (RCT) with larger sample and 12-month study duration and 12 of them were pilot testing. Nine of 12 pilot studies showed improved HbA1c; most of them resulted in varied dietary changes; and few of them showed improved diabetes distress and depression. Conclusion: Our review provided evidence that the application of mHealth technology for dietary intervention for adults with type 2 diabetes is still in pilot testing. The preliminary effects are inconclusive on physiological, dietary behavioral, and psychosocial outcomes.Examining reactivity to intensive longitudinal ecological momentary assessment: 12-month prospective study
AbstractCajita, M. I., Rathbun, S. L., Shiffman, S., Kline, C. E., Imes, C. C., Zheng, Y., Ewing, L. J., & Burke, L. E. (2023). Eating and Weight Disorders, 28(1), 1-5. 10.1007/s40519-023-01556-1AbstractPurposeTo examine the association between intensive, longitudinal ecological momentary assessment (EMA) and self-reported eating behaviors.MethodsSecondary analysis of the EMPOWER study—a 12-month observational study that examined the microprocesses of relapse following intentional weight loss using smartphone-administered EMA—was conducted. Participants were asked to complete four types of EMA surveys using a mobile app. For this analysis, only the number of completed random EMA surveys was used. Using linear mixed-effects modeling, we analyzed whether the number of completed random EMA surveys was associated with changes in self-reported dietary restraint, dietary disinhibition, and susceptibility to hunger measured using the Three-Factor Eating Questionnaire (TFEQ).ResultsDuring the 12-month study, 132 participants completed a mean of 1062 random EMA surveys (range: 673–1362). The median time it took for participants to complete random EMA surveys was 20 s and 90% of random EMA surveys were completed within 46 s. The number of completed random EMA surveys was not significantly associated with the TFEQ scores.ConclusionsIntensive longitudinal EMA did not influence self-reported eating behaviors. The findings suggest that EMA can be used to frequently assess real-world eating behaviors with minimal concern about assessment reactivity. Nonetheless, care must be taken when designing EMA surveys—particularly when using self-reported outcome measures.HIV Syndemic Factor Associations Among Adolescent Gay and Bisexual Men in the Youth Risk Behavior Survey 2015-2019: A Secondary Data Analysis
AbstractGarcia, D. R., Fletcher, J., Goldsamt, L., Bell, D. L., Zheng, Y., & Dunn Navarra, A.-M. (2023). The Journal of the Association of Nurses in AIDS Care : JANAC, 34(5), 440-458. 10.1097/JNC.0000000000000423AbstractThis analysis of the Youth Risk Behavior Survey examined HIV syndemic factor associations (substance use, violence, mental health, and HIV risk behaviors) among adolescent gay, bisexual, and other men who have sex with men-a population with the highest prevalence of undiagnosed HIV infections. The representative sample ( n = 644) exhibited low condom use (52%) and HIV testing (21%). Adjusted multivariate logistic regression models showed that Blacks were less likely to report HIV testing (adjusted odds ratio [aOR] = 0.06, 95% confidence interval [CI] [0.01-0.44], p < .01), whereas Hispanics were more likely to report four or more lifetime sexual partners (aOR = 3.75, 95% CI [1.49-9.44], p < .01), compared with Whites. A syndemic of substance use and intimate partner violence (sexual, sexual dating, and/or physical dating violence) was associated with early intercourse, multiple sexual partners, and drugs/alcohol before intercourse. Multiple syndemic factor exposures were associated with additive risk, suggesting multilevel approaches for HIV prevention. -
