The purpose of the study was to determine the influence of demographic variables such as gender, locality, delivery type, type of management, class, father’s education, father’s occupation, family income and birth order on mental health status. Mental Health Status inventory by Dr. Jagadeesh & A.K. Srivastva was administered to assess the mental health status of the subjects (N=200). To test the hypotheses, the collected data were analyzed using t-test and Chi-square test. Findings suggested that there is significant impact of demographic variables on mental health; the class of secondary school students is positively related to their mental health; the birth order of secondary school students is positively related to their mental health; the mental health status of urban area students is slightly better than of rural area students; the mental health status of caesarean delivered students is slightly better than that of normal delivered and the mental health status of girls is slightly better than that of boys
