All the women participated voluntarily in the study and signed an informed consent form. The study protocol was approved by the internal review board of the School of Medical Sciences, University of Campinas. Results The sociodemographic http://www.selleckchem.com/products/Cisplatin.html characteristics of the women in the study sample are shown in table 1. Table 1 Percentage of women without and with diabetes according to their sociodemographic and behavioural characteristics—bivariate analysis Of the 617 women interviewed, 22.7% reported
having diabetes. Of the women with diabetes (n=140), the mean age at onset of the disease was 56±11.2 years (median 55 years), reported at the time of the interview (figure 1). 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=0.001), more than two people living in the household (coefficient=0.656; SE of the coefficient=0.223; p=0.003); and BMI (kg/m2) at 20–30 years of age (coefficient=0.056, SE of the coefficient=0.023; p=0.014) (table 2). No association was found between menopausal status and diabetes. Figure 1 Age at the onset of diabetes over a lifetime (years). Cumulative survival N=617. Mean age at onset of the disease was 56±11.2 years (median 55 years). Cumulative continuation rate without diabetes was 56% at 92 years of … Table 2 Variables
associated with the presence of diabetes—Cox multiple regression analysis (n=428) Discussion The objective of this population-based study was to evaluate factors associated with age at onset of diabetes in women above 49 years. In the current study, the prevalence of self-reported diabetes was 22.7%, which could lead to misreporting. This finding is consistent with that of other studies. In Brazil, Lebrão et al7 showed Dacomitinib an 18.7% prevalence of self-reported diabetes among women aged above 60 years, and in the USA, for the period 2005–2008, it was estimated that 26.9% of people aged 65 years or more had diabetes, based on both fasting glucose and glycated haemoglobin levels.15 Self-rated health considered good or very good was associated with a higher rate of survival without diabetes.
