Measuring linear body segments for studying the growth of any individual anthropometric measurements have been an important tool from earliest times to the present days. The current investigation was cross sectional study undertaken among 1040 (boys=525; girls=515) Bengalee children aged 2-5 years in the Jalpaiguri district of West Bengal, India. There were 40 ICDS centres were selected randomly for the study. This study aims to investigate the age and sex variation of linear body segments such as Height, Sitting Height, Sitting Height/Height, Sitting Height/Sub Ischial Leg Length, Sub Ischial Leg Length, Sub ischial leg length Percentage, Upper Trunk Length and Upper Trunk Length Percentage. The study reveals that sex-specific age variation was found for all linear body segment variables except for the boy’s Body Mass Index. There was significant sexual dimorphism observed for some anthropometric variables such as Height, Sitting Height, Upper Trunk Length and Sitting Height/Sub-Ischial Leg Length. Sub Ischial Leg Length Percentage shows a negative correlation with Body Mass Index among both sexes whereas Upper Trunk Length Percentage shows a positive correlation with Body Mass Index among both sexes. The correlation of sub-ischial leg length with Upper Trunk Length, Upper Trunk Length Percentage and Sitting Height/Sub-Ischial Leg Length was observed in all age groups among both sexes. Correlation of Sitting Height with Sub ischial leg length was also observed at every age group for both sexes. The findings of the present study may help to determine the sex and age variations on linear body segments during growth among children.
