Age at Menarche Is Associated With Leg-Length Components Among the Adolescent Girls in West Bengal, India
Background
The relationship between early age at menarche (AAM) and body height (HT), including its different segments has not been extensively studied among non Western populations. Lengths of the lower (distal) part of the leg, such as knee HT (KH) and tibial length (TbL), are considered to be sensitive indicators of living conditions during early growth and development. Life history theory predicts that within a survival challenge the growth of vital parts of the body shall be prioritized over less essential parts. The present study hypothesized that earlier age at menarche would be associated with shorter tibial length in resource constrained settings.
Aim
To investigate the potential associations of menarcheal age with HT, KH, TbL, and other linear components of HT among the Bengalee schoolgirls aged 10–13 years.
Methods
Among the 208 girls aged 10–13 years, menarcheal status and age at menarche were determined by status quo and retrospective methods, respectively. Lower leg length was represented by two measures, KH and the supracutaneous measure of TbL. The differences in HT, sitting HT (SH), total leg length (LL), thigh length (TL), KH, and TbL, between pre-menarcheal-(PMG) and post-menarcheal girls (POMG), as well as between earlier menarcheal-(EMG) and later menarcheal girls (LMG), were assessed by student t-test and analysis of covariance.
Results
The POMG were heavier, taller and had higher adiposity than their PMG peers, without showing any significant age-difference. HT, knee HT, TbL, and TbL to HT ratio showed significant differences between the EMG and LMG. The EMG showed lower values for all of those measures and the strongest difference was observed for TbL. However, there were no significant differences in SH and SHR between EMG and LMG.
Conclusions
The study indicated a possible effect of early AAM on growth of distal body parts in a resource poor socioeconomic condition. Further studies on the relationship between growth and AAM among different populations living in different socio-ecological conditions could be worth conducting.
期刊介绍：
The American Journal of Human Biology is the Official Journal of the Human Biology Association.
The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field.
The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology.
Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification.
The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
