“…Several definitions are used to describe timing of puberty: age at menarche (11,12,16,21,(28)(29)(30), age at clinical onset of puberty (12,30,31) and age at peak height velocity (32). Using age at menarche, we found that the development of fat mass is significantly different in girls with an early and a late menarche.…”

Puberty is a critical period in body composition development. The influence of puberty on the development of fat mass asks for further investigation. We investigated the development of fat mass during puberty in a longitudinal prospective study in 152 healthy nonobese white girls, initial ages between 9 to 12 years. The influence of menarcheal age and the existing of tracking of fat mass have been analyzed. In 10 years time, participants were measured on eight time points. Various anthropometric data were collected, breast development was staged according to Tanner and body composition was determined with the dual‐energy X‐ray absorptiometry (DXA) scan. Calculations were made with the use of a linear mixed model. Fat mass increases from 7.9 kg (23.6%) at B1 to 18.5 kg (29.3%) at B5. Fat mass is higher in girls with an early menarche than in girls with a late menarche from B2. Girls in the quartile with initially the lowest fat mass have a chance of being in the same quartile after 10 years of 77% (P < 0.001). Girls in the quartile with initially the highest fat mass, have a risk of staying in the highest quartile of 55% (P < 0.001). Menarcheal age is of great influence on the development of fat mass. Girls with an early menarche, will have a bigger fat mass, especially at the end of puberty. Tracking of fat mass exists: a high amount of fat mass in early puberty will continue to exist at young adulthood.

“…In girls with early onset of breast development, the interval to menarche is longer (3 years or more) than in girls with later onset. [11][12][13] By 15 years of age, 98% of females will have had menarche. 3,14 Traditionally, primary amenorrhea has been defined as no menarche by 16 years of age; however, many diagnosable and treatable disorders can and should be detected earlier, using the statistically derived guideline of 14 to 15 years of age.…”

Young patients and their parents often are unsure about what represents normal menstrual patterns, and clinicians also may be unsure about normal ranges for menstrual cycle length and amount and duration of flow through adolescence. It is important to be able to educate young patients and their parents regarding what to expect of a first period and about the range for normal cycle length of subsequent menses. It is equally important for clinicians to have an understanding of bleeding patterns in girls and adolescents, the ability to differentiate between normal and abnormal menstruation, and the skill to know how to evaluate young patients' conditions appropriately. Using the menstrual cycle as an additional vital sign adds a powerful tool to the assessment of normal development and the exclusion of pathological conditions.

“…Criteria for subgrouping girls with different ages of pubertal onset were explained elsewhere (Martõ Â-Henneberg & Vizmanos, 1997). Only girls that started puberty from 10 y on (onset at 10 (n 68), at 11 (n 66), at 12 (n 37) and at 13 y of age (n 16)) were included in the analysis of body composition at pubertal onset.…”

Puberty begins with a characteristic subcutaneous body fat mass in each sex

Objective: To observe whether there exists a characteristic body fat mass at pubertal onset. Design: Longitudinal clinical follow-up (between ages of 10 and 15 y) with an annual visit in a sample of 469 children. They were grouped according to age of purbertal onset: boys with pubertal onset at the ages of 11 (n 59), 12 (n 88), 13 n 89) and 14 y (n 46), and girls with pubertal onset at the age of 10 (n 68), 11 (n 66), 12 (n 37) and 13 (n 16). Methods: Height, weight, upper arm circumference and four skinfold thicknesses were recorded annually. In boys testicular volume index was measured, and genital development was assessed on the Tanner scale; in girls mammary development was measured also using the Tanner scale. The sum of four skinfolds, body mass index, upper arm fat estimate and percentage body fat were calculated. Results: Boys presented a positive relation between the age of pubertal onset and body mass index (P`0.001), which was not observed in girls. Body mass index thus varied according to the onset of puberty in boys (P`0.001), but not in girls. The sum of four skinfolds, the upper arm fat estimate index and the percentage of body fat mass did not differ according to age of pubertal onset either in girls (P NS) or in boys (P NS). The characteristic adiposity of the puberty onset is progressively acquired during the previous years in all the groups. Conclusions: Puberty seems to begin with a characteristic subcutaneous body fat mass that is independent of the age of onset. This study supports the hypothesis of a close link between maturation and the development of an energy store in the form of adipose tissue in both sexes.
