[{'content': 'Best indicator for nutritional status for a child is – \nSelect and explain. \nA. Mid arm circumference, B. Head circumference, C. Rate of increase of height and weight, D. Chest circumference', 'role': 'user'}, {'content': "Answer: C \nExplanation: Health and development are intimately interconnected.\nProper nutrition of children is fundamental to the achievement of sustainable development.\nAnthropometric measurements are the most widely used indicators of nutritional status in a community.\nThe commonly used anthropometric measurements are -\nWeight\xa0\xa0\nLength / height\xa0\xa0\xa0\nArm circumference\xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0 \xa0\xa0\nChest circumference\nSkinfold thickness\xa0 \xa0 \xa0 \xa0 \xa0\xa0\n\nMeasurement of weight and rate in gain in weight are the best single parameters for assessing physical growth.\n\nThe comparison of a child's height and weight with the standard growth chart helps to determine if the particular child is within the expected normal range for his age, sex and socioeconomic status.\nIt does not indicate if the rate of growth of child was normal in the recent past.\nThe point to stress here is that it is very difficult to recognize a recent disturbance in growth by comparing weight or height with the reference standards because a clearly abnormal percentile position on the growth chart becomes evident only when the factors retarding growth are profound or if they have persisted for a considerable time.\nMeasurement of the velocity of growth or increment in unit time is a better tool for early identification of factors affecting growth and also for assessment of the usefulness of social and remedial measures.", 'role': 'assistant'}]
