The study included 198 boys and 180 girls with a mean age of 9.4 and 9.2 years, respectively. Unadjusted median (25–75 IQR) of 25(OH)D and iPTH concentrations were 13.8 (10 Dating in Ihrem 30er Meme.0–19.6) ng/mL and 33.1 (22.3–48.6) pg/mL, respectively, among boys and 9.9 (6.4–15.8) ng/ml and 47.8 (32.8–76.1) pg/mL, respectively, among girls. The prevalence of obesity and BMI z-score among boys was higher than girls (p<0.001). There were higher serum concentrations of PTH and lower 25(OH)D in girls, compared to boys (p = 0.036 and p<0.001, respectively). Regarding dietary intakes, the boys consumed more energy (p<0.001), calcium (p = 0.001), vitamin D (p = 0.012), magnesium(p = 0.002), and phosphorous (p<0.001) in comparison to girls.
Based on nonlinear regression designs, the connection between twenty-five(OH)D and you will iPTH are rapid. The fresh new projected fixed outcomes (and you may important mistake) were: a beneficial = step three.598 (0.110), b = 0.868 (0.465), c = 0.190 (0.141) in girls, and good = step 3.092 (4.495), b = 0.553 (cuatro.338), c = 0.014 (0.151) inside the men. Latest equations had been the following:
- Within the lady (Fig 1A): iPTH (pg/ ml) = 3.598 + 0.868 ? exp (-0.190 ? 25(OH)D ) and a good plateau during the iPTH peak in the 49 pg/mL are observed at a serum twenty-five(OH)D concentration of as much as 20 ng/mL (95% CI: 7.1 so you can thirty-two.2).
- From inside the males (Fig 1B): iPTH (pg/ ml) = 3.092 + 0.553 ? exp (-0.014 ? 25(OH)D) and there try zero plateau in the serum iPTH since 25(OH)D amount enhanced.
Because there is no plateau to possess iPTH for the boys, according to a mean gel log-iPTH intensity of 3.53 pg/mL, subjects were split up into two teams .
