Rate and risk predictors for development of self-reported type-2 diabetes mellitus over a 5-year period: the SHIELD study
International Journal of Clinical Practice, 06/22/2012
Rodbard HW et al. – Among this representative US adult population, the rate of developing type–2 diabetes mellitus (T2DM) was 7.2% over 5 years. Predictors of T2DM diagnosis identified in this analysis were readily obtainable via self–report.Methods
- The US Study to Help Improve Early evaluation and management of risk factors Leading to Diabetes (SHIELD) survey was a 5–year longitudinal study of adults with and without diabetes mellitus.
- Adults completed a baseline health questionnaire in 2004 and≥1 annual follow–up survey through 2009.
- Respondents with no self–reported diagnosis of diabetes at baseline were followed to measure rate of and assess risk factors for development of T2DM over 5 years.
- Among 8582 respondents without diabetes at baseline, 622 (7.2%) reported a diagnosis of T2DM over the subsequent 5 years.
- Increasing age, family history of T2DM, body mass index ≥30 kg/m2, abdominal obesity, excessive thirst, asthma, gestational diabetes and `high blood sugar without diabetes' significantly increased the risk of developing T2DM (p<0.05 for each).
- Good to excellent health status and self–reported circulatory problems decreased the risk (p<0.05 for each).
