About Me

Dr. Xiaotao Zhang earned his medical degree in Preventive Medicine in China. With a growing interest in disease prevention at the level of population health, he emigrated to the U.S to continue his education and training in Biostatistics and Epidemiology at Tulane University in New Orleans and The University of Texas Health Science Center in Houston. His research and experience are primarily focused on nutrition, the microbiome, cancer disparities and geriatric oncology. His research agenda is built upon multidisciplinary experiences studying the role of biological and modifiable factors in cancer disparities and cancer prevention. By merging epidemiologic methods with innovative techniques and bioinformatic/statistical strategies, his current research examines the role of biological and modifiable factors in cancer disparities and cancer prevention. He hopes to unravel risk factors and mechanisms to inform the development of new preventive interventions and clinical strategies.

Research

Malnutrition, a common and underrecognized condition in adults 65 and older. It often remains undiagnosed because the associated symptoms can be difficult to identify. Inadequate nutrition screening commonly leads to the mistreatment of this condition as a normal part of the aging process. The consequences of undiagnosed malnutrition can be detrimental to the health of an older person. The objective of dissertation was to evaluate malnutrition from an epidemiology perspective -- primary prevention: risk factors; secondary prevention: assessment and screening tools; and tertiary prevention: overall survival. Major findings from this dissertation include: Mini Nutrition Assessment was found to be the most valid and reliable predictor for malnutrition when compared with clinical diagnosis, while weight loss and BMI exhibited unfavorable validity and reliability; patients with frailty, functional impairment, abnormal gait speed, cognitive diagnosis, major depression, or poor performance status face a higher risk of developing malnutrition; malnutrition remains an independent risk factor for mortality in older cancer patients, especially those with solid tumors, despite nutritional recommendations regarding an increased dietary intake. Therefore, nutritional support, counseling, and interventions should be initiated as early as possible for this population. My research contributes empirical and theoretical knowledge to the fields of malnutrition and cancer care. Such knowledge is valuable to both academics and clinicians globally. Primary care physicians, nurses, and relatives should all help to enhance these patients’ awareness of their nutrition and health statuses. Recommendations for malnourished, frail, and functionally impaired older cancer patients may include an increased protein intake. One review article has been published by Current Oncology Reports (2019). It comprehensively describes the public health burden, malnutrition prevention, and relationship among cancer cachexia, malnutrition, and sarcopenia. Specifically, the research reveals comprehensive malnutrition prevention is required for improving the nutrition status among older adults with cancer.
