Abstract

Background Central obesity has been associated with a high risk of insulin resistance. Waist circumference and waist-to-height ratio are anthropometric indices for determining central obesity and have been associated with increased blood pressure, cholesterol, and insulin levels. In adults, fat distribution around the waist is a valid predictor of glycated hemoglobin (HbA1c)levels, and is currently recommended by experts as a diagnostic tool for diabetes. Central obesity measurement has advantages over fasting blood glucose and oral glucose tolerance tests, as it is simple and inexpensive to perform.Objective To assess for correlations between HbA1c level and waist circumference as well as waist-to-height ratio and to assess factors potentially associated with HbA1c levels in overweight and obese adolescents.Methods This cross-sectional study was done in four junior high schools in Yogyakarta, which were obtained by cluster sampling. Overweight and obese students who were generally healthy were included in the study. Subjects underwent waist circumference and waist-to-height ratio measurements, as well as blood tests for HbA1clevels.Results Sixty-seven children participated in the study, with 48 girls (71.6%) and 19 boys (28.4%). Waist circumference and HbA1c levels were not significantly associated (r=0.178; P=0.15). However, waist-to-height ratio and HbA1c levels had a weak positive correlation (r=0.21; P=0.04). Linear regression analysis revealed that waist-to-height ratio had a significant association with HbA1c level (P=0.02), but age, sex, and nutritional status did not.Conclusion Waist-to-height ratio is correlated with HbA1c levels in overweight and obese adolescents.

Abstract

Background In developing countries, 5-10% of infants suffer from failure to thrive. Adequate feeding is the most crucial factor for optimal growth in early life. Objective To assess the differences in growth velocity at 4 to 6 months of age, based on the infant feeding practices. Methods This cross-sectional study involving 4 to 6 month-old babies from 6 public health centres in Yogyakarta was performed from August to November 2016. Data on body weight, and growth velocity as they related to weight at birth were collected. Subjects were divided into groups according to their feeding practices. Results Of 173 subjects, 130 (75%) infants were exclusively breastfed, 19 infants (11%) were given breast milk and formula, 14 (8%) infants were given breast milk and complementary food (8%), and 10 (6%) infants were given formula and complementary food. The mean growth velocity z-scores by group were as follows: exclusively breastfed 0.04 (SD 1.15) (95%CI -0.16 to 0.24), breast milk and formula -0.61 (SD 0.84) (95%CI -1.01 to -0.21), breast milk and complementary food -0.69 (SD 1.14) (95%CI -1.35 to -0.04), formula and complementary food 0.23 (SD 1.50) (95%CI: -0.84 to 1.31). The mean difference in growth velocity between the exclusively breastfed vs. breast milk and formula groups was 0.65 (SD 0.28) (95%CI: 0.10 to 1.20; P=0.02); vs. breast milk and complementary food was 0.73 (SD 0.32) (95%CI: 0.10 to 1.37; P=0.02); and vs. formula and complementary food was -0.19 (SD 0.37) (95%CI: -0.93 to 0.55; P=0.61). Conclusion Exclusively breastfed have the most optimal growth velocity compared to infants who experience other feeding practices.
