Area-Level Socioeconomic Status and Incidence of Abnormal GlucoseMetabolism The Australian Diabetes, Obesity and Lifestyle Study

RESEARCHDESIGNANDMETHODSdThe Australian Diabetes, Obesity and Lifestyle study is a national, population-based, longitudinal study of adults aged$25 years. A sample of 4,572 people provided complete baseline (1999 to 2000) and 5-year follow-up (2004 to 2005) data relevant for these analyses. Incident AGMwas assessed using fasting plasma glucose and 2-h plasma glucose from oral glucose tolerance tests, and demographic, socioeconomic, and behavioral data were collected by interview and questionnaire. Area SES was defined using the Index of Relative Socioeconomic Disadvantage. Generalized linear mixed models were used to examine the relationship between area SES and incident AGM, with adjustment for covariates and correction for cluster design effects.
