Poor glucose regulation is associated with declines in well-being among older men, but not women.

Abstract: Glucose regulation is a key aspect of healthy aging and has been linked to brain functioning and cognition. Here we examined the role of glucose regulation for within-person longitudinal trajectories of well-being. We applied growth models to data from the Berlin Aging Study II (N ϭ 955), using insulin resistance as an index of glucoregulatory capacity. We found that poor glucose regulation (higher insulin resistance) was consistently associated with lower levels of well-being among older men but not women. Ou… Show more

“…Direct effects were analyzed using multiple regression with discrimination, depression, and anxiety entered as predictors; well-being entered as the outcome; and gender, income, perceived health, smoking status, age, exercise, and insulin resistance entered as covariates. All covariates were selected based on sample size constraints and potential to act as confounds, as previous studies have reported associations between these factors and both discrimination [10,11,31,32] and well-being [33][34][35][36][37][38]. Glycemic control (i.e., HbA1c) was initially considered as a covariate in place of insulin resistance, but the latter was chosen for the final model because it shared a significant correlation with at least one other variable in the model, and is considered a more reliable indicator of longterm metabolic health [39].…”

“…This is even more dramatic since almost one third of the participants was not aware of the disease (Table 1). In addition being a risk factor for cardiovascular disease and cognitive decline, a recent analysis of BASE-II data suggested that the capacity to regulate the glucose metabolism is associated with well-being among older men 43 .…”
