Child health is a matter of concern in developing countries like India.Predominantly, Pneumonia and Bronchiolitis comprising the Lower Respiratory Tract Infections along with Upper Respiratory Tract Infections have some severe implications on the health of pediatric population when they occur recurrently.Pneumonias can prove fatal at times especially in the rural areas where immediate health care facilities remain unavailable as compared to urban areas where immediate interventions are possible due to presence of tertiary health care centres.Malnutrition is another serious health related hazard which can have devastating effects on the overall growth and development of the child and also is quite rampant in our society.The main objective behind this book was to assess the relation between socio-demographic and environmental factors with respiratory infections and malnutrition. Knowledge, Attitude and Progress was also assessed among the mothers and some striking findings were revealed.The results and conclusions drawn from this study will help us in formulating a stronger health care system which vetoes the ill effects of ARI and malnutrition on the health of pediatric population.
