Feinkohl I, et al. - The role of obesity, diabetes and hypertension as risk factors for age-related cognitive impairment was examined in this analysis. Researchers obtained original baseline data from three studies (OCTOPUS, DECS, SuDoCo) for secondary analysis of cross-sectional associations of diabetes, hypertension, blood pressure, obesity (body mass index [BMI] ≥30 kg/m²) and BMI with the presence of cognitive impairment in log-binomial regression analyses. Findings revealed that older people who were obese had a higher prevalence of cognitive impairment vs normal weight and overweight people, and that is independent of co-morbid hypertension or diabetes. Data reported that none of the remaining risk factors were correlated with impairment.
