Age Variations and Sexual Dimorphism in Linear Body Segments among Children Aged 2-6-Years of Bengalee Ethnicity from Arambagh, West Bengal, India

Background Sitting height (SH), sub ischial leg length (SILL) and the sitting height/leg length ratio (SH/SILL) are useful tools for assessing human body proportions. They are often used to detect the presence of abnormal growth, especially in school-aged children. Materials and Methods Our cross-sectional study was conducted among 1012 preschool children aged 2 to 6-years from Integrated Child Development Services (ICDS) scheme centers at Bali Gram Panchayat, Arambagh, Hooghly District, West Bengal, India. Anthropometric measurements like height, weight, SH were measured following standard protocol. Results There was no age combined significant sex difference in any variable. However, age specific sex differences were there in few age groups. Highly significant (p<0.001) age variations existed in all variables. The body mass index (BMI) was significantly (p<0.01) negatively correlated with SILL (r=-0.443), SILLP (r=-0.302) and UTL (r=-0.346) in both sexes. It was significantly (p<0.01) positively associated with UTLP (r=0.302). Moreover, SILL was significantly positively correlated with UTL in both sexes (boys, r=0.821 and girls, r=0.871; p<0.01), whereas it was significantly negatively associated with UTLP (boys, r=-0.590 and girls, r=-0.552; p<0.01) in the participants. Conclusion Our results suggest that, in both sexes, there were significant age differences in SILL, SILLP, upper trunk length (UTL) and unified technology learning platform (UTLP). The BMI had significant associations with these variables in both sexes. Moreover, SILL had significant correlation with UTL and UTLP among the participants.
