“…The take-off of the growth spurt (TO) in girls appears on average around 8-9 years, about 2 years earlier than in boys. Peak height velocity (PHV) occurs in girls aged 11.5 years, and in boys aged 13.5 [2,3]. In the assessment of developmental age during puberty, the markers of secondary sexual characteristics appear to be one of the most important.…”

“…Intensive physical activity is connected with delayed puberty because of negative energetic balance, special diet, and corticotropic axis stimulation in increased stress leading to gonadoliberin excretion disturbances [13]. The relationship between the percentage of fat tissue and the dynamics of the puberty process has been demonstrated in girls [3,14]. Leptin secreted by adipose tissue is a key factor affecting the age of puberty onset since it has been shown to have a direct effect on the secretion of gonadotropins and gonadotropin releasing hormone (GnRH) [15].…”

“…A relatively late event during puberty is menarche, which usually occurs about 1.2 to 1.3 years after reaching a maximum rate of linear growth (peak height velocity, PHV) [2]. In recent years the mean age at menarche in Poland ranged from 12.5 to 13 years [3,4].…”

Developmental gynecology uses methods practiced in auxology -the science of human ontogenetic development. An important and jointly used concept in gynecology and auxology is the concept of developmental age, which, unlike calendar age, is a measure of the biological maturity of the organism, indicating the stage of advancement in the development of certain features or body systems. Developmental age assessment methods include: a) morphological (somatic) age -body height and weight, b) secondary sex characteristics -breast in girls, genitalia (penis and testes) in boys, and pubic hair in both sexes, c) bone age -hand and wrist x-ray, and d) dental age. An important marker of developmental age is also age at menarche, treated as a late indicator of puberty in girls. All of these methods are useful in the context of assessing regularity and disorders of puberty, such as delayed puberty. The paper discusses developmental age assessment methods that can be used to diagnose delayed puberty as well as the causes of delayed puberty in girls. It should be emphasized that in assessing the process of physical development of a given individual, the cooperation of specialists in the field of developmental gynecology, pediatrics, auxology, dentistry, endocrinology, and dietetics would be the most desirable.

“…AIS can be considered a disorder of growth, with a close association between patient's maturity and a risk of spinal curve progression [3]. An informative marker of female physical maturity and remaining growth potential during adolescence is the age of menarche [4]. Research studies revealed that the progression of the spinal deformity was related to growth velocity and thus significantly greater before menarche than after menarche [3].…”

“…The observed differences of menarcheal age of AIS patients as compared to healthy population have been attributed to hormonal disturbances involving estrogen, melatonin, and leptin [5,8]. Several studies have linked high body mass index (BMI) with earlier puberty [4,9]. Interestingly, low BMI has also been found to be associated with AIS [10,16], although literature data regarding nutritional status of scoliotic patients are inconclusive [11,12].…”

Factors affecting puberty gingivitis in Polish girls with adolescent idiopathic scoliosis

et al. 2020

Objectives: Age at menarche and hormonal disturbances have been linked to the occurrence and severity of adolescent idiopathic scoliosis (AIS). Concomitantly, an increase in the production of sex hormones during puberty may result in steroid hormones-related gingivitis. Thus, the study aimed to assess the prevalence and factors affecting puberty gingivitis, including menarcheal status, in female patients with AIS and control subjects. Material and methods:The study group was comprised of 59 girls aged 12-16 years with AIS and 50 healthy controls. Dental examination included the assessment of oral hygiene, gingivitis, and dental caries intensity. Data were statistically analyzed with a significance taken as p < 0.05.Results: There wasn't any statistically significant difference in the age at menarche and menarcheal status of both groups. During regression analysis, three predictors significantly affected gingival status of girls: oral hygiene, orthopedic condition, and laterality of the curve. Scoliosis and left convex of the curve significantly increased the index of gingival inflammation. Conclusions:The results indicate that gingivitis is frequent among female adolescents with AIS, due to poor oral hygiene and higher susceptibility to inflammation. It emphasizes a need for a development of preventive strategy for scoliotic patients, since incipient periodontal problems in children may turn into irreversible advanced periodontal diseases in adults.

Objectives The aim of this study was to assess time intervals between the age at menarche (AM) and age at sexual initiation (ASI) in Polish women born before and after the political transformation period in Poland. Methods Participants were 518 women born between 1959 and 2001 in Poland. AM and ASI were based on self‐report. Three birth cohorts were distinguished based on the year of birth: I (1959‐1979), II (1980‐1989), III (1990‐2001). Three categories of AM were distinguished: early maturing (<12.0 years), average (12.0‐13.0 years), and late maturing (≥14.0 years). Temporal intervals between AM and ASI were calculated. Results Both AM and ASI decreased in subsequent birth cohorts, with the greatest changes observed in the women born after 1989. No significant differences in the time interval between AM and ASI were observed between birth cohorts. However, the time interval between AM and ASI differed by AM category (H = 74.16; P < .001). The longest time period between AM and ASI occurred in early maturing girls (7.13 years) and the shortest in late maturing girls (3.25 years). Conclusions Despite the transformation and decline in both AM and ASI, the time interval between these two characteristics remained stable. Significant differences in the time interval were found among women stratified by AM. The time interval between AM and ASI was longer in girls who matured early in comparison to those maturing late or at the average time.
