Effects of BMI and height at prepuberty age on height growth. LOESS smooth curve and shaded 95% confidence interval of height for age. (a) By body mass index (BMI) categories at 11 years of age for males. P-values at 11 years and 17 years of age for the difference of height between BMI categories at 11 years of age were shown. (b) By BMI categories at 9 years of age for females. P-values at 9 years and 15 years of age for the difference of height between BMI categories at 9 years of age were shown. BMI was categorized according to World Health Organization (WHO) 2007 references: overweight was BMI-for-age greater than +1 SD above the WHO Growth standards median, obesity was BMI-for-age greater than +2 SD above the WHO Growth standards median. Thinness was BMI-for-age <-2 SD of the WHO Child growth standards median. Normal BMI was BMI-for-age between -2SD and +1SD of WHO Growth standards. SD: Standard deviation. p-values from Kruskal-Wallis’ test. (c) By height categories at 11 years of age for males according to WHO 2007 references. (d) By height categories at 9 years of age for females according to WHO 2007 references.
