Abstract

OBJECTIVE:

To estimate temporal changes in the prevalence of diabetic ketoacidosis (DKA) at diagnosis of type 1 or type 2 diabetes in youth and to explore factors associated with its occurrence.

METHODS:

Five centers identified incident cases of diabetes among youth aged 0 to 19 years starting in 2002. DKA presence was defined as a bicarbonate level <15 mmol/L and/or a pH <7.25 (venous) or <7.30 (arterial or capillary) or mention of DKA in the medical records. We assessed trends in the prevalence of DKA over 3 time periods (2002-2003, 2004-2005, and 2008-2010). Logistic regression was used to determine factors associated with DKA.

RESULTS:

In youth with type 1 diabetes (n = 5615), the prevalence of DKA was high and stable over time (30.2% in 2002-2003, 29.1% in 2004-2005, and 31.1% in 2008-2010; P for trend = .42). Higher prevalence was associated with younger age at diagnosis (P < .0001), minority race/ethnicity (P = .019), income (P = .019), and lack of private health insurance (P = 008). Among youth with type 2 diabetes (n = 1425), DKA prevalence decreased from 11.7% in 2002-2003 to 5.7% in 2008-2010 (P for trend = .005). Higher prevalence was associated with younger age at diagnosis (P = .001), minority race/ethnicity (P = .013), and male gender (P = .001).

CONCLUSIONS:

The frequency of DKA in youth with type 1 diabetes, although stable, remains high, indicating a persistent need for increased awareness of signs and symptoms of diabetes and better access to health care. In youth with type 2 diabetes, DKA at onset is less common and is decreasing over time.
