    Abstract: OBJECTIVE—To study the effect of body composition and adiponectin on insulin resistance and β-cell function in schoolchildren during puberty. RESEARCH DESIGN AND METHODS—Plasma adiponectin level and its relationships with insulin sensitivity and β-cell function were analyzed in 500 randomly recruited nondiabetic Taiwanese schoolchildren (245 boys and 255 girls) aged 6–18 years in a national survey program for diabetes in 1999. Insulin resistance and β-cell function were evaluated by homeostasis model assessment (HOMA). Plasma adiponectin concentrations were determined with radioimmunoassay. RESULTS—Plasma glucose levels remained stable, whereas insulin resistance increased with a compensatory rise in β-cell function during this period. A transient drop of adiponectin level with a trough at 10–12 years was found in boys but not in girls. This pubertal drop of adiponectin levels in boys coincides with the sharp rise in testosterone concentration. A negative correlation between testosterone levels and adiponectin concentration was also noted in boys (r = −0.142, P = 0.032). Plasma adiponectin levels correlated inversely with relative body weight, fasting insulin concentrations, and insulin resistance index by HOMA in boys aged 15–18 years and in girls aged 11–14 years. No association was observed between adiponectin levels and β-cell function by HOMA. CONCLUSIONS—There is a transient drop in the level of adiponectin during male puberty, correlated with the increase in testosterone level in boys. Plasma adiponectin levels were inversely correlated with obesity and insulin resistance in boys and girls during the pubertal period.

    Abstract: OBJECTIVE—To study the effect of birth weight on risk of type 2 diabetes in the schoolchildren in Taiwan. RESEARCH DESIGN AND METHODS—From 1992 to 1997, all schoolchildren aged 6–18 years were screened for diabetes in Taiwan Province. This cohort consisted of 1,966 patients with diabetes and 1,780 randomly selected subjects with normal fasting glycemia (NFG). Questionnaire interviewing was designed to classify diabetes. The birth weight was obtained from the Taiwan’s Birth Registry. After merging the data, there were 978 subjects, including 429 with type 2 diabetes and 549 with of NFG enrolled in the present analyses. RESULTS—The odds ratios (95% CI) for type 2 diabetes, after adjusting age, sex, BMI, family history of diabetes, and socioeconomic status, were 2.91 (1.25–6.76) for children with low birth weight ( & lt;2,500 g) and 1.78 (1.04–3.06) for those with high birth weight (≥4,000 g) when compared with the referent group (birth weight 3,000–3,499 g). The risk of diabetes was still 64% higher in the high birth weight group [odds ratio (OR) 1.64 (95% CI 0.91–2.96)], even after adjustment for gestational diabetes mellitus (GDM). Patients with type 2 diabetes who were born with high birth weight were more likely to have a higher BMI and diastolic blood pressure as well as a higher family history of diabetes compared with those with low birth weight. CONCLUSIONS—A U-shaped relationship between birth weight and risk of type 2 diabetes was found in the schoolchildren aged 6–18 years in Taiwan. Schoolchildren with type 2 diabetes who were born with low birth weight had different metabolic phenotypes compared with those born with high birth weight.
