Background and Aims. Childhood obesity is one of the most serious and urgent public health problems in
both developed and developing countries(1). Puberty itself is a state of relative insulin resistance and there is
an increase in basal and stimulated insulin secretion during the progression through normal puberty(2), and
metabolic syndrome occurs with a high rate in overweight youth. This Petai China Study determines the
prevalence of metabolic syndrome among the obese adolescents in Indonesia for estimating the magnitude of
this health problem and evaluate a definition for its early diagnosis in the young population.
Materials and Methods. Subjects were taken by a cluster random sampling from the list of junior high school
and high school located in north Jakarta. A cross-sectional study with a survey method was done to students
from 5 schools agreed for the study. Physical examination and anthropometric measurement were done to all
participating students. A fasting blood venous sample was collected among the overweight population to
determine glucose, trygliceride, HDL cholesterol and insulin levels, and also among lean students for study
control. Prevalence of the metabolic syndrome was estimated according to the National Cholesterol Educa-
tion Program Adult Treatment Panel III- Asia Pacific Perspective(3).
Results. Data were analyzed out of 510 adolescents participants, 51% were female, with the average of 14.84
+/- 1.46 year of age. Mean of BMI is 22.32 +/- 4.77 kg/m2. The prevalence rate of obesity was 4.9% (95% CI
26.31 - 36.75). With the blood test done to 47 overweight students and 11 lean students referring to the parents
permission. Metabolic syndrome found in 29.78% of population. Out of 14 obese subjects (BMI exceeding the
95th percentile) metabolic syndrome criterions found in 5 students (35.71%). The prevalence rate of the
metabolic syndrome increased significantly with increasing insulin resistance ( P for trend, < 0.001 ) after
adjustment for sex group and degree of obesity.
Conclusion. The prevalence of the metabolic syndrome is high among overweight Chinese adolescents in
Jakarta, Indonesia and it increases with worsening obesity.
