Maturation Stages

Introduction: Pubertal growth stages are important periods in orthodontic treatment with functional appliances and orthognathic surgery. Pubertal growth prediction, which determines the amount of growth that has taken place and estimates the remaining growth, can influence diagnosis, treatment goals, treatment plans, and orthodontic treatment outcomes, especially in cases requiring growth intensity or growth completion. Determination of pubertal growth stages is more accurate when performed using physiological maturation indicators than chronological age. There are several maturation indices that can be used to predict the pubertal growth stage, such as hand-wrist maturation, cervical vertebrae maturation index (CVMS), dental calcification, peak height velocity of body height (PHV), and menarche in females. The aim of this study was to identify the differences and correlation between hand-wrist, CVMS maturation stages, peak height velocity (PHV), canine and M2 calcification stages, and menarche age (of female subjects). The study also aimed to describe the pubertal growth curve plot of female and male subjects. Materials and Methods: This is a retrospective study with a cross-sectional approach, which included 279 females and 144 males aged 8-17 years. Subjects had digital lateral cephalograms, hand-wrist, and panoramic radiographs. The hand-wrist maturation stage was analyzed using the Fishman method, CVMS using Baccetti et al.’s method, and the stages of dental maturation were assessed using Demirjian and Goldstein method. PHV was measured from standing height using a wall-mounted plastic stadiometer, while menarche was analyzed through interviews. Statistical analysis by ANOVA, post hoc analysis, and Spearman’s rank correlation coefficient were determined with Excel Mega Stat. Results: There were significant differences between females and males in CVMS and hand-wrist (P< 0.05) except for radius union (Ru). No significant differences in canine and M2 calcification between females and males were observed. PHV females increased by 7.89 cm at 11-12 years, while males increased by 9.9 cm at 13-14 years. Menarche occurred at the age of 12.2 years on average, with the oldest being 14.7 years and the youngest being 9.6 years. The correlation between females’ and males’ hand-wrist and CVMS was very high. The lowest correlation in females was between menarche and CVMS and in males, it was between PHV and canine. Conclusion: Maturation stages of hand-wrist, CVMS, and PHV females were earlier than males. Pubertal growth curves plot of females tended to skew to the left, demonstrating that the time from the beginning to the peak of pubertal growth is shorter than that from the peak to the end of pubertal growth, while pubertal growth curves plot of males tended to skew to the right, demonstrating that the time from the beginning to the peak of pubertal growth is longer than that from the peak to the end of pubertal growth.

Adolescent Growth Spurt

The prediction of the timing of the pubertal growth spurt could be helpful in planning some types of orthodontic treatment. It has been suggested that information from hand—wrist radiographs could be used for this purpose. Insufficient attention has been paid to the distinction between ossification events and bone stages. In the present paper it is shown that the uncertainty of prediction of the timing of the peak height Velocity from ossification events in the hand and wrist, is generally large and so they are of limited value for this purpose.

AbstractObjectivesIn general population, there are three phases in the human growth curve: infancy, childhood and puberty, with different main factors involved in their regulation and mathematical models to fit them. Achondroplasia children experience a fast decreasing growth during infancy and an “adolescent growth spurt”; however, there are no longitudinal studies that cover the analysis of the whole post-natal growth. Here we analyse the whole growth curve from infancy to adulthood applying the JPA-2 mathematical model.MethodsTwenty-seven patients, 17 girls and 10 boys with achondroplasia, who reached adult size, were included. Height growth data was collected from birth until adulthood. Individual growth curves were estimated by fitting the JPA-2 model to each individual’s height for age data.ResultsHeight growth velocity curves show that after a period of fast decreasing growth velocity since birth, with a mean of 9.7 cm/year at 1 year old, the growth velocity is stable in late preschool years, with a mean of 4.2 cm/year. In boys, age and peak height velocity in puberty were 13.75 years and 5.08 cm/year and reach a mean adult height of 130.52 cm. In girls, the age and peak height velocity in puberty were 11.1 years and 4.32 cm/year and reach a mean adult height of 119.2 cm.ConclusionsThe study of individual growth curves in achondroplasia children by the JPA-2 model shows the three periods, infancy, childhood and puberty, with a similar shape but lesser in magnitude than general population.

We reviewed the growth characteristics of American boys and girls from published studies, including age at takeoff, age at peak height velocity, peak height velocity, duration of puberty, and the magnitude of the pubertal contribution to adult height. Age at takeoff is highly variable and sex-dependent. The mean takeoff age in children growing at an average rate is ∼11 years in boys and 9 years in girls, and peak height velocity occurs at a mean age of 13.5 years and 11.5 years, respectively, in these children. Whole-year peak height velocity is 9.5 cm/y in boys and 8.3 cm/y in girls, with slight variations in the different studies. The contribution of pubertal growth to final height is ∼30 to 31 cm in boys, accounting for 17% to 18% of the final height, and 27.5 to 29 cm in girls, accounting for 17% of the final height. The magnitude of pubertal growth has a negative correlation with age at takeoff, but no correlation with final height. Age at takeoff, however, correlates highly with pubertal stage, but correlates negatively with duration of puberty.

Abstract. Bioassayable somatomedin-A (SM-A) and serum concentrations of testosterone (T) and dehydroepiandrosterone (DHEA) were determined longitudinally in 26 normal boys during puberty. The mean trend of SM-A increased in relation to age, pubic hair development and peak height velocity (PHV) and significant correlations were observed with testicular volume, height velocity and T (all P < 0.001) but not with DHEA. In relation to growth SM-A increased mainly during 12 to 6 months prior to PHV but no further increase was seen in the 6 months thereafter. Thus pubertal growth and development have to be taken into account in the evaluation of changes in bioassayable SM-A concentrations in boys.

Nf1 Gene

Previous studies have suggested that children with neurofibromatosis type 1 are shorter than their unaffected counterparts as an effect of a germline NF1 gene mutation. The pathophysiology of this effect is still uncertain. The purpose of this study was to characterize longitudinal growth in children with neurofibromatosis type 1 in order to assess growth velocity and its influence on stature. Longitudinal height data were collected for 188 patients with a confirmed clinical diagnosis of neurofibromatosis type 1. Children with neurofibromatosis type 1 had population mean heights statistically different from the general population, with a reduced peak height velocity during pubertal growth. In addition, there were no significant differences in the timing of peak height velocity during puberty between the general population and those with neurofibromatosis type 1. These data demonstrate that short stature in neurofibromatosis type 1 is due in part to subnormal height acquisition during puberty.

Anthropometric Profile

The anthropometric profile assessment is an important aspect to consider during the growth stages of youth sport practitioners due to its usefulness in controlling maturity status and overall health. We performed an anthropometric profile evaluation in a sample of youth goalkeepers (n = 42) during a training camp, dividing them into three categories based on their years from peak height velocity (YPHV). We also checked if the selection of goalkeepers was associated with the birth quartile. The results showed that most of the participants’ anthropometric parameters followed the normal trend according to the maturation stages. However, several subjects showed an overweight/obese condition and/or high waist circumference. Non-optimal values were found, mostly in the group of goalkeepers around the PHV. In addition, no selection based on birth quartile was seen. Therefore, the anthropometric profile and body composition of youth goalkeepers are physiologically affected by maturity status. However, several subjects were found to be overweight/obese and at cardiometabolic risk, suggesting that children and adolescents, although practicing sport, should pay attention to potentially contributing factors such as the attainment of the recommended levels of physical activity, lowering sedentary time, and adopt a healthy lifestyle.

Summary Background/Objectives The aims were to study the presence of a secular trend in (a) age at peak height velocity (PHV), (b) velocity at PHV, and (c) duration of skeletal maturation in relation to PHV. Material/Method Two groups of children: 100 children (63 boys, 37 girls) born between 1969–1973 and 71 children (49 boys, 22 girls) born between 1996 and 2000, were compared. Age and velocity at PHV were measured on individual growth velocity curves. Skeletal maturation stages were assessed on hand-wrist radiographs, and duration from the skeletal maturation stages to PHV was determined. Results Age at PHV occurred significantly earlier (0.47 years, CI 95% 0.19–0.76, P &lt; 0.001), and velocity at PHV was significantly higher (0.68 cm/year, CI 95% 1.47–2.06, P &lt; 0.003) in children born 1996–2000 compared to 1969–1973. No significant difference in duration of skeletal maturation was seen between the groups. Skeletal maturation stages occurred significantly in the following order before PHV for both genders: PP2= 2.18 years (P = 0.002), MP3= 1.60 year (P = 0.008), S 1.07 year (P = 0.003), and MP3cap 0.38 year (P = 0.037). Limitations Most radiographs were taken before PHV, the duration thus mainly reflects the early event of pubertal growth spurt. Conclusion A secular trend was evident: significantly decreased age at PHV and significantly increased velocity at PHV. No evidence of a secular trend regarding duration of the skeletal maturation in relation to PHV was found. Due to the declining age at PHV, the skeletal maturation stages occurred earlier in relation to chronological age.

The identification of young soccer players’ maturation level throughout puberty is crucial to verify the influence of aspects that interfere on sport performance, such as body height and physical capacities. The aim of the present study was to verify the differences in physical performance of young soccer players in maturation stages before and after peak height velocity. This study comprised 49 soccer players (14.49 ± 1.00 yrs) belonging to the youth teams of a club in the city of Fortaleza. Body weight, height and trunk-cephalic height were measured. Somatic maturation was estimated using distance in years from peak height velocity (DPHV). 10 Meters Sprint and 20 Meter Flying Sprint, Modified Illinois, Jump Height (CMJ), RAST and Yo Yo IRT 1 tests were applied. Standardized Mean Difference (SMD) and Confidence Intervals (CI = 90%) were used to compare the study variables (PRE-PHV vs POST-PHV). Our findings showed that POST-PHV group showed higher values in CMJ (3/3/97, Very likely) and RAST (peak, average, minimum power) and lower in the 20 Meter Flying Sprint (100/0/0, Most Likely) when compared to the PRE-PHV group. We concluded that young soccer players with somatic maturation after peak height velocity presented better capacity of lower limb strength, anaerobic power and speed.

ABSTRACT Objective: To identify the prevalence of overweight in adolescents according to different classification criteria for obesity and somatic maturation stages. Methods: Cross-sectional study in 10 schools in a city from Southern Brazil, with 1715 adolescents. Height, weight, waist circumference, and neck circumference (NC) data were collected. Body Mass Index was classified according to World Health Organization (WHO) and Centers for Disease Control and Prevention criteria, and the waist-to-height ratio (WHtR) was classified according to Brazilian and European cut-off points. Somatic maturation was obtained through the Peak Height Velocity. The prevalence data were compared between sex and stages of somatic maturation; the concordance between different criteria was verified. Results: The prevalence of overweight was high in both sexes; WHO criteria showed that 34.5% of boys and 29.3% of girls were overweight. For the WHtR, the prevalence was 28.4% in boys and 23.7% in girls. NC classified 13.8% of boys and 15.8% of girls as being overweight. The prevalence of overweight was higher in adolescents before complete somatic maturation. Conclusions: The prevalence of overweight was high among adolescents. The boys presented higher frequency of overweight, except if NC was used to classify them. Adolescents before somatic maturation had a higher prevalence of overweight. NC showed a lower ability to track obese adolescents.

ObjectiveKnowledge of the biological parameters of pubertal growth spurt allows verification of secular changes and exploration of the timing of puberty. The aim of the study was to estimate final height, age at peak height velocity (APHV), and peak height velocity PHV (cm/y) in children and adolescents living at moderate altitude in Colombia.MethodsA cross-sectional study was designed in 2.295 schoolchildren from Bogotá (Colombia) with an age range from 5.0 to 18.9 years. Height (cm) was assessed. Preece–Baines model 1 (1PB) was used to make inferences about mathematical and biological parameters.ResultsThe five mathematical parameters estimated in general have reflected quality in the fit to the model, reflecting a small residual error. Final height was reached in boys at 170.8 ± 0.4 cm and in girls at 157.9 ± 0.2 cm. APHV was estimated at 12.71 ± 0.1 years in boys and 10.4 ± 0.2 years in girls. Girls reached APHV 2.2 years earlier than boys. In relation to PHV (cm/y), boys reached higher growth speed in height (7.4 ± 0.4 cm/y), and in girls it was (7.0 ± 0.2 cm/y).ConclusionIt was determined that final height was reached at 170.8 ± 0.4 cm in boys and 157.9 ± 0.2 cm in girls, and APHV (years) and PHV (cm/ye) were reached relatively early and with average peak velocity similar to Asian and Western populations. A large-scale longitudinal study is needed to confirm these findings.
