Results
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 (10.0–19.6) 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 activities, the connection anywhere between 25(OH)D and you will iPTH try exponential. Brand new estimated repaired consequences (and you will standard error) were: a great = step 3.598 (0.110), b = 0.868 (0.465), c = 0.190 (0.141) in the females, and you can a = step 3.092 (4.495), b = 0.553 (4.338), c = 0.014 (0.151) inside the men. Finally equations was the following:
- Inside girls (Fig 1A): iPTH (pg/ ml) = step 3.598 + 0.868 ? exp (-0.190 ? 25(OH)D ) and a beneficial plateau inside iPTH top in the forty-two pg/mL is noticed at the a solution 25(OH)D intensity of up to
20 ng/mL (95% CI: eight.step 1 to 32.2). - During the boys (Fig 1B): iPTH (pg/ ml) = step three.092 + 0.553 ? exp (-0.014 ? 25(OH)D) there is no plateau into the gel iPTH due to the fact twenty five(OH)D focus increased.
As there are zero plateau to possess iPTH within the males, according to a hateful serum journal-iPTH intensity of 3.53 pg/mL, victims had been divided in to a couple of groups . In accordance with the exponential picture offered above, it can be determined you to into the people, an indicate serum diary-iPTH concentration of 3.53 pg/mL received at solution twenty-five(OH)D levels out-of 15 ng/mL.Read More »Medical and you may biochemical sex-situated properties off participants are given during the Dining table step 1
