Sexual maturity assessment in Indian children—a study from western India

Abstract

Abstract Objectives Pubertal assessment is crucial as puberty is the transition from childhood to adulthood. Pubertal assessment, growth, and secular trend in puberty need to be explored further in India. The objectives were to assess Sexual Maturity Rating (SMR) among children and establish normative data of puberty from western India. We also compared age of attainment of various stages of puberty with BMI and secular trend in menarche. Methods A cross-sectional observational study was undertaken at a tertiary care pediatric center. The study population were healthy girls and boys between 6 and 18 years. Demographic data was noted. Anthropometry and SMR assessment (Tanner staging) were performed. The age of menarche was noted among the girls and their mothers. Data were analyzed using SPSS 21. Results In girls, median age of thelarche, pubarche, and menarche was 9.37 (8.5–10.2), 10.18 (9.87–10.49), and 12.55 years (12.41–12.75) respectively. There was an early appearance of thelarche but menarche was delayed in overweight-obese girls (statistically not significant). Age of menarche showed a shift to left in girls as compared to their mothers (p=0.036). In boys, median age of testicular stage 2 and pubarche was 10.7 (9.9–11.8) and 11.6 years (11.1–12.1) respectively. In overweight-obese boys the pubertal milestones were achieved earlier (statistically not significant). Conclusions Normative data on pubertal assessment from western India is presented. Age of menarche shows a shift to left in girls as compared to their mothers. Pubertal milestones were observed at a younger age in overweight obese children which was not significant.
