The aims of the present study were to determine the body composition and to assess the nutritional status on the basis of body composition parameters in Nepalese children. Body fat percentage (BF%), fat mass (FM), and fat-free mass (FFM) of 1,988 (1,016 boys and 972 girls) Nepalese children aged 6 to 10 years were calculated from triceps and subscapular skinfolds. FM and FFM were then divided by height-squared in meter to determine the fat mass index (FMI) and fat-free mass index (FFMI), respectively. Growth curves of BF% and FFM for Nepalese children remained at a low level compared to international data. BF%, FM, and FMI of Nepalese girls were significantly (p < 0.001) higher than Nepalese boys, whereas FFM and FFMI of Nepalese boys were significantly (p < 0.001) higher than Nepalese girls of all age groups. BF%, FM, and FFM were significantly correlated with almost all anthropometric parameters in both sexes. Growth curves of BF% and FFM showed that the undernutrition prevailed in Nepalese children. BF% and FFM were good indicators for measuring nutritional status in Nepalese children. Sexual dimorphism of fat patterning was present in Nepalese children.

Atomic polarizability is an essential theoretical construct to define and correlate many physicochemical properties. It exhibits periodicity and has a relationship with other periodic descriptors. Although a number of scales are available to compute atomic polarizability, the final scale is yet to be designed. In this venture, we have invoked a new empirical approach to compute the atomic polarizability of 103 elements of the periodic table, considering the conjoint action of other periodic descriptors, namely effective nuclear charge (Zeff) and absolute radii (r). The proposed approach is [Formula: see text], where “e” represents the electronic charge, Zeff is the effective nuclear charge, r is the absolute radius, and α is the polarizability. Our computed atomic polarizability follows all sine qua non of the periodicity. Our model significantly exhibits the relativistic effect too. A close agreement between our computed data and other available theoretical and experimental results demonstrates the efficacy of our proposed approach. Furthermore, we have established the polarizability equalization principle in terms of our computed data.
