To read the full abstract: Acta Paediatr. 2019 Jun;108(6):1008–1015.This meta-analysis reviews the association between physical activity and age at menarche.The onset of puberty is a multifactorial trait including a wide range of genetic and environmental components. Age at menarche has been associated with several environmental factors such as ...

To read the full abstract: Pregnancy Hypertens. 2019 Jan;15:134–140.This observational cohort study highlights the negative association between age at menarche and blood pressure in pregnancy, and the probable relationship with BMI and insulin resistance.Age at menarche (AAM) is influenced by genetic and environmental determinants (1). Given that some...

Brief summary: This longitudinal UK cohort study examined the prospective associations between objectively measured physical activity, independently of BMI, and pubertal timing in boys and girls.This large study analyzed device-measured physical activity and its intensity in relation to puberty timing, using accelerometers worn on the right hip. A previous meta-analysis reported that female athletes had later age at menarche than non-athletes (1), but it...

To read the full abstract: Front Endocrinol (Lausanne). 2018 Feb 28;9:54Secular trends in birth parameters1-3, growth4,5, and timing of puberty6-8 are observed in normal populations. Changes in nutrition, better access to health care, and other environmental factors have been implicated as causative factors for those changes. Here, the authors assessed secular ...

Brief Summary: This review summarizes the role of macronutrients and hormones which regulate energy balance and sexual maturation by conveying energy availability information to the GnRH system.30 years ago, Kennedy and Mitra were the first to use translational studies to show that nutrition is a key factor regulating puberty timing1. Their seminal protocol modified the size of rat litters to affect weight increase and showed that nutritional ...

The timing of puber...

Brief Summary: This international cohort study of 404 patients identified rare likely damaging variants in the gene MECP2 in patients with central precocious puberty. Translational experiments showed that GnRH neurons in mice express Mecp2.Over the last few years, several studies have provided insight into the epigenetic regulation of the onset of puberty1-3. DNA methylation, histone post-translational modifications and non-c...
