How health is affected by behaviors, economics, and social structure

Health is affected by various factors. These are known as the determinants of health. Behavior in the health context refers to how people engage in various activities that maintain their health and prevent diseases. Uchino, Uno, & Holt-Lunstad, 1999()

Therefore, health is extremely important in the maintenance of a good health status as well as in the prevention of disease. A good example is in heart disease, lung cancer and stroke which have risk factors that relate to the patient's behavior. For example, for lung cancer, smoking is a risk factor. Therefore, the behavior of the individual regarding smoking or living around smokers increases the risk of contracting lung cancer. For heart disease and stroke, the risk factor is eating foods that are high in fat. Therefore, the individual should eat a more balanced diet with plenty of fruits and vegetables to prevent heart disease. The individual should also consider keeping physically fit in order to steer away from the risk factors of heart disease and stroke. Therefore, the behavior of the individual, others surrounding the individual and health care providers can help in improving the health of the individual. Therefore, behavior is an important determinant of health.

Regarding economics, the financial status of an individual influences the quality of health care that they receive. For example, in the U.S., the insured individuals have access to high quality health care while the uninsured population has to result to lower quality because they cannot afford to pay for more expensive health care options Hurley, 2001.

Additionally, the economic status of a country affects the delivery of health care since delivery of health care is primarily a government responsibility and where the government is unable to finance healthcare, the quality of health provided will be low Connelly, 2004()

Social structure also affects health since it contributes risk factors for some diseases or conditions. For example, overcrowding is a risk factor of tuberculosis and other respiratory diseases. Social structure also affects health since it defines the health seeking behavior of the individuals in the society Uchino et al., 1999.

Some religions, for example, do not believe in seeking health care from hospitals and doctors.

Three stages of medical technology development

The three stages of development of medical technology are the scientific background and development of the idea for the product, development, approval and distribution of the product and diffusion, adoption and utilization of the product. In the first stage, there is building the need for the product and developing the concept of the product. This basically involves finding out what the product to be developed is expected to achieve and how it will achieve this. This is an important step since it guides the direction that the other stages take. If the product is not properly conceptualized, there is the risk of not achieving the desired objectives of the development program. Also, there is the risk of veering off the development route.

The second stage is whereby the product is actually developed using the right scientific methods and technology. After the product is developed, it needs to be tested and approved by the relevant body. Depending on the product, the time and type of testing that needs to be done varies. Some products need clinical testing such as drugs and machines while others need only basic testing in the laboratory. In the U.S., drugs and chemical substances are approved by the FDA (Food and drugs administration). The FDA received applications for approval after which it thoroughly tests the products for a lengthy amount of time before giving the manufacturer the green light to continue with mass production and distribution.

The last stage is the diffusion of the product, adoption and utilization. This involves the marketing of the product to the target market as well as other promotional activities that create awareness of the product in order to increase its acceptability and usage.

Major trends in population demographics over the past 80 years

Over the past century, the population of people in the U.S. has more than tripled from about 76 million people in the U.S. To about 290 million people as of the year 2000. The growth in the population for the 1990s was the largest in the history of the U.S. At 32.7 million people. The population of the U.S. grew increasingly each decade by about 28% with suburbs rather than cities accounting for most of the metropolitan growth. The west side of the country also grew faster than the other regions in every decade of the 20th century Hobbs & Stoops, 2002()

The age and sex composition of the population has also changed greatly. About 90 years ago in the 1920s, half of the U.S. population was less than 22.9 years of age but at the present, half of the population is more than 35.3 years. This is the country's highest median age of all times. The under 5's represented the largest age group in the year 1900 and again in the year 1950. However, in the year 2000, the largest age groups were ages 35-39 and 40-44. This was as a result of the baby-boom generation of the 1950s. The population of those aged above 65 also increased ten times from 3.1 million in the 1900s to 35 million in the year 2000. In terms of sex, the sex ratio (ratio of males per 1,000 females) declined every decade from 1910 to the 1980. However, it increased from the 1980s to the 1990s. The west had the highest sex ratio and the northeast had the lowest sex ratio for the whole century Hobbs & Stoops, 2002()
