(Computerization of Health Records) A health care issue that has been in the news lately is the computerization of health records. This possibility is being approached cautiously because of sensitive privacy and security concerns, among others. Computerizing health records could make it easier for patients to share their health profiles and histories among their various health care professionals. This could improve the quality of health care, help avoid drug conflicts and erroneous drug prescriptions, reduce costs and in emergencies, could save lives. In this exercise, you’ll design a “starter” Health Profile class for a person. The class attributes should include the person’s first name, last name, gender, date of birth (consisting of separate attributes for the month, day and year of birth), height (in inches) and weight (in pounds). Your class should have a constructor that receives this data. For each attribute, provide set and get functions. The class also should include functions that calculate and return the user’s age in years, maximum heart rate and target-heart-rate range, and body mass index (BMI; see Exercise 2.32). Write an application that prompts for the person’s information, instantiates an object of class Health Profile for that person and prints the information from that object—including the person’s first name, last name, gender, date of birth, height and weight—then calculates and prints the person’s age in years, BMI, maximum heart rate and target-heart-rate range. It should also display the “BMI values” chart from Exercise 2.32. Use the same technique as Exercise 16.16 to calculate the person’s age.

(Body Mass Index Calculator) We introduced the body mass index (BMI) calculator in Exercise 1.14. The formulas for calculating BMI are

Exercise 1.14

(Test-Drive: Body Mass Index Calculator) By recent estimates, two-thirds of the people in the United States are overweight and about half of those are obese. This causes significant increases in illnesses such as diabetes and heart disease. To determine whether a person is overweight or obese, you can use a measure called the body mass index (BMI). The United States Department of Health and Human Services provides a BMI calculator at www.nhlbisupport.com/bmi/. Use it to calculate your own BMI. An exercise in Chapter 2 will ask you to program your own BMI calculator. To prepare for this, use the web to research the formulas for calculating BMI.
