  virtually from Toronto\n\nAbstract\n\nAlmost half of the global adult pop
 ulation suffers from gum disease\, which\, if untreated\, can lead to toot
 h loss. When the unit of analysis is the tooth\, we need to account for th
 e baseline number of teeth and the rate of tooth loss over time when analy
 zing the marginal effect of health risk factors on changing gum disease ou
 tcomes over time. I will present two recent works on methods to model comp
 lex longitudinal dental data subject to informative cluster size. One inco
 rporates inverse probability censoring weights into cluster weighted gener
 alized estimating equations and the other incorporates cluster weights int
 o a multistate model. The methods are applied study the effects of metabol
 ic syndrome on the progression of gum disease using data from the Veterans
  Affairs Dental Longitudinal Study.\n\nSpeaker Bio\n\nAya is Assistant Pro
 fessor in the Division of Biostatistics at the Dalla Lana School of Public
  Health\, University of Toronto. Her research focuses on developing statis
 tical methods to analyze correlated data and to remove biases that emerge 
 from informative cluster size\, study design\, missing data\, or misclassi
 fication in multilevel observational studies and complex surveys. She has 
 collaborated with researchers from oncology\, nephrology\, anesthesiology\
 , and oral health. Aya’s research is funded by the Connaught Fund\, Nation
 al Science and Engineering Council of Canada\, Canadian Institutes of Heal
 th Research\, and National Institutes of Health.\n
