“…In a cross-sectional study performed on 97 female students in Tanzania, body fat percentage was 22% greater in postmenarche girls than in premenarche girls and age at menarche and body muscle percentage were negatively correlated (beta-coefficient −0.12) [6]. A cross-sectional study by Gemelli et al [26] reported that girls with experience of menarche had more mass of skeletal muscle than those without menarche.…”

Sarcopenia is defined as an age-related loss of skeletal muscle and is associated with several health disorders. Causes of sarcopenia, which included physical inactivity, alcohol, dietary habits, and smoking, have been researched. The present study was undertaken to examine the association between reproductive span and sarcopenia in Korean women. Data obtained from 2008 to 2011 Korea National Health and Nutrition Examination Surveys (KNHANES) were analyzed. We defined sarcopenia based on the cut-off values of the Foundation for the National Institutes of Health (FNIH) sarcopenia project criteria: ASM/BMI < 0.512 for women. Reproductive span was defined as years from menarche to menopause, and we divided the 3970 study subjects into three groups by reproductive span tertile. Multivariate logistic regression analysis was used to determine adjusted ORs for the relation between reproductive span and sarcopenia. The prevalence of sarcopenia in the study was 17.7% (704 of 3970). Multiple logistic regression analysis was performed using weighted populations. After adjusting for covariates, reproductive span was found to be inversely associated with the risk of sarcopenia [Tertile 1 = 1 (reference); Tertile 2, odds ratio (OR) = 0.927, 95% confidence interval (CI) = 0.863–0.995; Tertile 3, OR = 0.854, 95% CI = 0.793–0.915].

“…And the greater adiposity found in juveniles, compared to children, may also be related to biological maturation [19]. In Gemelli, Farias, and Spritzer [20], the occurrence of menarche was associated with body fat gain.…”

“…Additionally, a high level of physical exercise can promote pubertal development delay [27]. The age at which menarche occurs varies considerably between countries; in Brazil, studies carried out between 2010 and 2014 showed a mean age of 12.2 years [20]. Camargo [28] found the presence of menarche in only 26% of its sample of 132 Brazilian athletes from RG, with an average of 13.2 years.…”

Introdução: A ginástica rítmica é uma modalidade esportiva estética, cujas regras encorajam biotipo longilíneo e magro, expondo ginastas ao risco de deficiência energética relativa no esporte (RED-S). Objetivo: Analisar comportamentos de risco para RED-S em ginastas brasileiras de alto rendimento de categorias pré-infantil, infantil e juvenil, com destaque nacional e internacional. Métodos: 36 atletas brasileiras (10 pré-infantis, 9 infantis e 17 juvenis) foram avaliadas quanto à composição corporal, maturação sexual e risco de transtornos alimentares. A investigação de volume de treinamento, ciclos menstruais, monitoramento de densidade mineral óssea e de exames laboratoriais, ocorrência de fratura por estresse, acompanhamento nutricional especializado e consumo de suplementos alimentares realizou-se por questionário de Ackerman adaptado. Resultados: As ginastas apresentaram volume de treinamento semanal de 27,32 horas, % de massa gorda de 12,1 ± 2,8, sendo as infantis as de menor adiposidade. Quanto à maturação sexual, 66,1% encontravam-se na fase púbere, e nenhuma atleta chegou à fase pós-púbere. A frequência de risco de transtornos alimentares foi de 55,6%, sendo as juvenis mais afetadas (70,6%). Apenas 47,1% das juvenis apresentaram menarca. Somente 36,1% têm acesso a nutricionista esportivo, enquanto 16,7% avaliaram a densidade mineral óssea ao menos uma vez na carreira, e 52,8% realizam exames laboratoriais regularmente. Foi relatada fratura por estresse por 22,2% das ginastas, sendo 44,4% nas juvenis. Encontrou-se suplementação alimentar em 36,1% das ginastas, com destaque para vitaminas C e D e proteínas. Conclusão: Foram encontrados comportamentos de risco para RED-S em jovens ginastas rítmicas brasileiras de alto rendimento, com destaque para transtornos alimentares, especialmente na categoria juvenil.

“…Albeit many studies focused on precocious puberty have been conducted by researchers, the causes in most cases in girls remain unknown. Most epidemiology studies from US [ 22 – 25 ], England [ 26 ], Germany [ 27 , 28 ], Danmark [ 8 ], Brazil [ 29 ], Italy [ 30 ], and China [ 31 , 32 ] et al have confirmed the positive association between obesity and earlier attainment of puberty for girls. Our results are consistent with the prior studies and suggested that, among girls, overweight and obesity were significantly associated with increased odds of CPP, independent of children’s birth characteristics, feeding practices, and social-demographic data.…”

Obesity is a risk factor for central precocious puberty: a case-control study

Background Obesity is an important underlying cause of central precocious puberty (CPP), but previous large studies are flawed by using just age and breast examination to diagnose CPP. We aimed to determine whether overweight and obesity in childhood increases hormonally diagnosed CPP. Methods Our retrospective, case-control study recruited 846 children diagnosed as having CPP and randomly sampled 1650 healthy control subjects in Xingtai Third Hospital in China between November 2018 and March 2021. Information was obtained from an electronic medical record and questionnaire investigated in the outpatient visit. Observations were made before the a priori hypothesis. Unconditional logistic regression for analysis was used to determine whether overweight and obesity status and duration of overweight/obesity were associated with CPP. Results Overweight and obesity were significantly associated with increased odds of CPP among girls, even after adjusting for birth weight, exclusive breastfeeding for 6 month, household income, maternal overweight, paternal overweight, and maternal menarche age (overweight: the adjusted odds ratio (aOR) (95%CI): 1.92 (1.16, 3.24), p = 0.02; obesity: aOR (95%CI): 1.78 (1.13, 3.48), p = 0.03). Furthermore, the effects of overweight and obesity were significant when ongoing for 1 to 2 years, 2 to 3 years, and greater than 3 years, but not at less than 1 year. For boys, association between obesity and increased odds of CPP was observed (aOR (95%CI): 1.68 (1.09, 3.75), p = 0.03). The effects of overweight and/or obesity were only significant when ongoing for greater than 2 years. Conclusions Prolonged overweight and obesity in early childhood may be risk factors for CPP, especially in girls. Weight loss might be an important approach for the prevention of precocious puberty in children.
