Anthropometric study is useful for forensic investigation and personal identification. In forensic and medical examination, the determination of stature and age are important parameters. There is a lot of variation in estimating stature from foot dimension measurements in different age groups, especially in the case of children of various races and populations. Foot dimensions as the most valuable evidence that may be available at the crime scene may estimate the stature of an individual. In the present cross-sectional study was done on randomly selected ICDS (Integrated Child Development Scheme) centres, there were 25 ICDS selected. A total of 541 (boys: 280 & girls: 261) children of Jalpaiguri aged 2-5 years were considered for the study. There was significant sex differences found in mean stature, right foot length, left foot length, right foot breadth, left foot breadth. Study reports significant age variations for all anthropometric parameters such as stature and foot dimensions among boys, girls, and unknown samples. The regression coefficients were statistically significant (p<0.05) and for the R showed high positive correlation for most of the variables except for foot index. Present research reported significant age trends of foot measurements and stature among studied children. For the prediction of stature, foot length was found more accurate and reliable among foot length, foot breadth and foot index. Present study reported positive linearity between foot dimensions with age and stature facilitates the formulation of age and sex specific regression equation which can be utilised for estimation of age and stature of preschool children from foot anthropometry.

Introduction: In today’s Era, mobile phones have become an essential part of our lives but this excessive dependence on smart phones has led to Nomophobia as adults are the most active user of the smart phones, they are prone to develop Nomphobia. This much dependency on mobile phones is affecting their mental health, academic performance and social relationships.
Methods: A Cross sectional and descriptive study approach was used in conducting this study among 108 adults selected by using convenient sampling technique at selected urban community of Kolkata. Data was collected using structured questionnaire. Statistical analysis included Fischer exact test.
Results: The data was tabulated and analysed by using descriptive statistics. It was inferred that 1.85% of adults had no Nomophobia, 45.37% of adults had mild, another 45.37 had moderate and 7.41% of adults had severe levels of Nomophobia. The study concluded that there was no association between level of Nomophobia and selected socio demographic variables.
Discussion: The study provided a source of information about the levels ofNomophobia prevalent among adults in Kolkata.This study will help to broaden the perspective about Nomophobia so that community interventions can be done to subside the concerned issue.
Conclusion: The study revealed that prevalence of Nomophobia in adults is 52.78%. Statistically there was no association between Nomophobia and socio-demographic variables.
