Factors Associated With The Age Of The Onset Of Diabetes In Women Aged 50 Years Or More: A Population-based Study

Objective: Investigate factors associated with the onset of diabetes in women aged more than 49 years. Design and methods: Cross-sectional, populationbased study using self-reports with 622 women. The dependent variable was the age of occurrence of diabetes using the life table method. Cox multiple regression models were adjusted to analyse the onset of diabetes according to predictor variables. Sociodemographic, clinical and behavioural factors were evaluated. Results: Of the 622 women interviewed, 22.7% had diabetes. The mean age at onset was 56 years. The factors associated with the age of occurrence of diabetes were self-rated health (very good, good) (coefficient= -0.792; SE of the coefficient=0.215; p=0.0001), more than two individuals living in the household (coefficient=0.656, SE of the coefficient=0.223; p=0.003), and body mass index (BMI) (kg/m2) at 20-30 years of age (coefficient= 0.056, SE of the coefficient=0.023; p=0.014). Conclusions: Self-rated health considered good or very good was associated with a higher rate of survival without diabetes. Sharing a home with two or more other people and a weight increase at 20-30 years of age was associated with the onset of type 2 diabetes.411Mensing, C., Boucher, J., Cypress, M., National standards for diabetes self-management education (2005) Diabetes Care, 28, pp. S72-S79Seshasai, S.R., Kaptoge, S., Thompson, A., Emerging risk factors collaboration.
