Demographic and personal factors associated with metabolic control and self-care in youth with type 1 diabetes: a systematic review.

Optimal use of recent technological advances in insulin delivery and glucose monitoring remain limited by the impact of behaviour on self-care. In recent years, there has been a resurgence of interest in psychosocial methods of optimizing care in youth with type 1 diabetes. We therefore sought to examine the literature for demographic, interpersonal and intrapersonal correlates of self-care and/or metabolic control. Studies for this systematic review were obtained via an electronic search of Medline, Embase, Cumulative Index to Nursing and Allied Health Literature and PsycINFO databases. Seventy studies fulfilled the inclusion criteria. These studies have indicated that identifiable individual characteristics in each domain are robustly associated with metabolic control and/or self-care in children and adolescents. We present these characteristics and propose a theoretical model of their interactions and effect on diabetes outcomes. There is currently no consensus regarding patient selection for insulin pump therapy. In this era of scarce healthcare resources, it may be prudent to identify youth requiring increased psychosocial support prior to regimen intensification. The importance of this review lies in its potential to create a framework for rationally utilizing resources by stratifying costly therapeutic options to those who, in the first instance, will be most likely to benefit from them.
