Background: Since the normal fasting plasma glucose
level has decreased to below 100 mg/dL, the range for
impaired fasting glucose (IFG) has expanded. Early
detection and management of IFG in adolescents can
reduce and delay the development of diabetes. Therefore,
the prevalence of IFG in adolescents and its related
factors were investigated in this study.
Methods: The study population comprised of 2,850(1,584 boys and 1,266 girls) students from 14 different
middle schools in Korea. The participants’ height, weight
and fasting plasma glucose were measured. The
participants’ age, body mass index (BMI), number of
siblings, their parents’ monthly income, weight at birth,
and physical activity were assessed using self-recording
Results: The prevalence of IFG is 4.3% (boys; 5.3%,
girls; 3.0%). Univariate analysis showed that rural
community (OR = 1.67) and monthly income of parents
(P = 0.021) were factors associated with IFG for boys,
while rural community (OR = 2.18) and obesity (OR =
4.84) were associated with IFG for girls. Multiple logistic
regression analysis showed that the risk of IFG is
associated with skipping breakfasts (OR = 3.50
[2.01~6.09]) and high monthly income of parents (P =
0.011) for boys, while obesity (OR = 5.95 [2.58~13.75])
is the associated factor for girls.
Conclusion: The factors strongly associated with IFG
for adolescents were skipping breakfast and obesity for
boys and girls, respectively.
