Human Development

– From Infancy to Geriatrics

Growth: generally refers to

changes in size and structure of a living organism

Development:Development:1. Generally refers to

successive changes in the process of

one’s natural growth 2. Occurs through the maturation of physical

and mental capacities and learning

Growth and development are ongoing processes beginning at birth

and ending at death.

Individuals have unique healthcare needs based on their level of

development

Health care workers need to be familiar with each

developmental stage in order to recognize maladaptive

behavior and provide quality healthcare.

GeriatricsAccording to the U.S. Government on Aging: 1. There are approximately 29 million people aged 65 or older (that’s 12% of the current population) in the U.S. 2. By the year 2030, this number is expected to increase to 20%.

Life Stages

Infancy

1. Physical changes – height and weight (born weighing between 5½ and 10 pounds—generally double weight by 9 months)

2. Muscular and neurological motions – progress from uncoordinated movements of the head and extremities to development of fine motor coordination

3. Teeth – generally born without teeth; usually develop them by the 1styear

4. Vision – poor at birth (capable of focusing on objects 8 to 12 inches from the face), but improves by 1 year to permit a longer range of visual recognition and hand-eye coordination

5. Language – the language of a newborn is the cry; by one month, an infant’s repertoire expands to include throaty or gurgle sounds.

6. Feeding – hungry at irregular intervals; eats every 2 to 3 hours

7. Social being – responds to human voice and touch
