Obesity screening for Indonesian adults using BMI and percentage body fat: Redefined cut-off points
12 Results: Triglyceride concentrations before and after DM-MCT diet did not increase significantly (146.0 ± 86.43 mg/dl vs. 144.0 ± 114.0 mg/dl), whereas triglyceride concentration before and after diabetes diet was significantly decreased (151.6 ± 102.66 mg/dl vs.117.5 ± 50.34 mg/dl). Conclusion: Medium chain triglyceride in nutrition therapy does not increase triglyceride concentration in T2DM.

However the index is not a measure of body fat. Since obesity is defined as an excess accumulation of body fat, determination of obesity should consider an individual’s body fat level. Method: The current study aimed to determine the optimum BMI cut-off values for obesity screening based on body fat in Indonesian adults. Stature and body weight were measured from 600 Indonesians aged 18—65 years (males, n = 292; females, n = 308) and their BMI was calculated. Percent body fat (%BF) was determined using the deuterium oxide (D2 O) dilution technique. Obesity was defined using WHO criteria: %BF > 25% for males and %BF > 35% for females. A receiver-operating characteristic (ROC) curve was performed to provide the best cut-off values of BMI as a screening tool for obesity defined by %BF in males and females. Two existing BMI cut-offs for obesity (23 kg/m2 and 25 kg/m2 ) were also evaluated for sensitivity and specificity.
Journal Abstracts Result: The new BMI cut-offs for the determinations of obesity were 21.9 kg/m2 for males and 23.6 kg/m2 for females respectively. The existing BMI cut-off values showed low sensitivity in our samples (between 18.4 and 71.1%) and the new proposed cut-offs increased sensitivity to reach 66.7—88.5%, respectively. Conclusions: Instead of existing BMI cut-off values, the new proposed values are recommended as better screening values for obesity in this population.

Objectives: To assess 25(OH)D serum levels in women and determine factors that can influence these levels. Method: This cross-sectional study was conducted on 156 healthy Indonesian women during the dry season, measured serum 25(OH)D levels, examined two single nucleotide polymorphisms in the vitamin D receptor (TaqI and BsmI), and assessed lifestyle factors by using questionnaire. Results: The mean serum 25(OH)D level was 18.8 ± 7.0 ng/mL, 148 subjects categorised as either deficient and insufficient, and eight were categorised as sufficient. However, there was no significant difference in serum 25(OH)D levels between obese (OG) and non-obese groups (NG). All participants were heterozygous (T>C for TaqI and A>G for BsmI).
