Abstract
Present work deals with the statistical analysis of anthropometric parameters and sociodemographic data of adolescent girls to check the prevalence of Anemia in the Rural and Tribal area of Udham Singh Nagar District of Uttarakhand. The study is based on secondary data related to anthropometric and socio-demographic parameters of 520 adolescent girls (170 Rural and 350 Tribal). The study was conducted by categorizing the whole dataset into two categories according to their age i.e. Early adolescent girls & Late adolescent girls. Major conclusions of the study are: 1. On basis of distribution patterns of the seven parameters viz. Weight, Height, Waist Circumference, Hip Circumference, Waist to Hip Ratio, BMI & Haemoglobin obtained using EasyFit 5.6 Professional software, it was concluded that probability distribution of only one parameter i.e. Height in the case of Rural Late Adolescent Girls category follows Normal Distribution. Other than it, all of the parameters in different categories of Rural and Tribal Adolescent Girls follow Non-Normal distribution. 2. On the basis of Karl Pearson’s Correlation Coefficient and Chi-square test of Independence relationship between various anthropometric parameters and socio demographic parameters was found. Only one anthropometric parameter i.e. Waist to Height Ratio was negatively correlated with Haemoglobin. It was also found that Haemoglobin depends on sociodemographic parameters viz. No. of Family members, No. of siblings, Age at the time of Menarche, Standard of Living Score, Food Habit, No. of Home prepared meals taken in a day, Menarche Achieved, Menstrual Flow, Avoiding Food during Menstrual Cycle, Nutrition Education on Anemia, Fasting Frequency and Socio-economic class. 3. On the basis of Z test used for comparison of various anthropometric parameters and Haemoglobin for Rural and Tribal adolescent girls, it was concluded that there is a significant difference between the Weights of Rural and Tribal Early Adolescent Girls.. A significant difference was found between Weight, Height, Waist Circumference, Hip circumference, Waist to Height Ratio and Haemoglobin in case of Rural and Tribal Late adolescent girls. A significant difference was also observed in prevalence of Anemia in Rural and Tribal Late adolescent girls. 4. On the basis of Multiple Linear Regression (MLR) and Binomial Logistic Regression (BLR) models developed for prediction of Haemoglobin and BMI, it was concluded that Multiple Linear Regression provides better result than Binomial Logistic Regression model for estimating Haemoglobin and BMI in case of Rural Late Adolescent Girls, Tribal Early and Late Adolescent Girls categories. However, BLR model was found better than MLR for estimating Haemoglobin in case of Rural Early Adolescent Girls. The findings of the study are expected to provide useful information to the nutritionist and health experts for future policy planning in the study area.
