This study examined the effects of sociodemographic variables such as
ethnicity, socioeconomic status (SES), and family structure on disease
control in 58 children with diabetes stratified by ethnicity and SES.
Three dependent variables were chosen to evaluate the disease control
of the study participants, including HbA(1) values averaged over the
year prior to study participation, number of hospitalizations, and num
ber of hypoglycaemic blackouts. SES and family structure, but not ethn
icity, were the primary risk factors to disease control. Children from
low SES families were in poorer glycaemic control (mean HbA(1) = 12.6
%) and experienced more episodes of hypoglycaemia-related loss of cons
ciousness (mean = 0.5 per patient) than did children from middle incom
e families (mean HbA(1) = 10.4%; mean blackouts = 0.1 per patient). In
addition, children from middle-class, two-parent families were in bet
ter metabolic control than all other groups. These results indicate th
at it may not be ethnicity per se, but other factors that often covary
with ethnic status, that may pose a risk to the disease status of chi
ldren and adolescents with diabetes.
