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.
Considering nonlinear regression activities, the connection ranging from twenty five(OH)D and you may iPTH is great. The estimated fixed effects (and you may practical error) were: a great = step 3.598 (0.110), b = 0.868 (0.465), c = 0.190 (0.141) for the lady, and you may an excellent = 3.092 (4.495), b = 0.553 (4.338), c = 0.014 (0.151) in males. Last equations had been as follows:
- Inside women (Fig 1A): iPTH (pg/ ml) = 3.598 + 0.868 ? exp (-0.190 ? 25(OH)D ) and a great plateau inside the iPTH top at the forty two pg/mL is seen in the a serum twenty-five(OH)D concentration of around 20 ng/mL (95% CI: eight.step 1 to help you thirty two.2).Read More »Systematic and you can biochemical sex-built services away from participants are given for the Table 1
