A China health declaration form will also ask the individual because of their height, weight, and other body dimensions, as well as some private info about the individual. This information is needed in order to calculate an average height and weight in the country. This is done by dividing the person's weight in g by his/her height in centimeters, to get his/her approximate height and weight in centimeters. This measurement will be utilized by the doctor in diagnosing the individual with any health state and will help determine the best treatment options.
