After completing this class, students will be able to differentiate between growth and development, describe principles of growth and development, and list factors that influence it. Growth is a physical change in size, while development is an increase in complexity of function and skills. Development is influenced by maturation, environment, genetics, and occurs sequentially in a head-to-toe and center-to-extremities pattern. Factors like nutrition, family, health, culture and temperament also influence growth and development from conception through the lifespan.

CONCEPTS OF GROWTH AND DEVELOPMENT Spring Semester 2014- 2015
LEARNING OUTCOMES  After completing this class, you will be able to: 1. Differentiate between the terms growth and development. 2. Describe essential principles related to growth and development. 3. List factors that influence growth and development.
Why we study human growth & development Nurses need to be knowledgeable about the characteristics and needs of the age groups with which nurses come into contact in order to  perform accurate health assessment  Description normal growth & development, individual differences  Explanation typical and individually different development  provide health promotion throughout the life span to optimization positive development & prevention difficulties  ensures safe and effective age-specific client care.
What is growth & development Growth is physical change and increase in number and size of cells.  It can be measured quantitatively.  Indicators of growth include: height, weight, bone size, and dentition.  The pattern of physiological growth is similar for all people. However, growth rates vary during different stages of growth and development.  (rapid during the prenatal, neonatal, infancy, and adolescent stages and slows during childhood & minimal during adulthood).
What is growth & development Development is an increase in the complexity of function and skill progression.  Development is an increase of capacity and skill of a person through growth , maturation and learning in order to adapt to the environment.  Development is the behavioral aspect of growth (e.g., a person develops the ability to walk, talk, and think).
Development Maturation is :  The physical change in the complexity of body structures resulting in final differentiation or refinement in the functioning of cells  An increase in competence and adaptability of human being capacities  A qualitative changes
Development  Learning: involves changes in behavior that occur as a result of maturation and experiences with environment.  Experience: Stimuli in the surrounding that modify developmental characteristics through the learning  Adaptation: interplay between individual and environment
growth & development  Growth and development are independent, interrelated processes. For example, an infant’s muscles, bones, and nervous system must grow to a certain point before the infant is able to walk, or talk. Growth generally takes place during the first 20 years of life; development takes place during that time and also continues after that point.  There are Principles of growth and development see Box 20–1.
Principles of Growth and Development  Growth and development are continuous, orderly, sequential processes influenced by maturational, environmental, and genetic factors.  All humans follow the same pattern of growth and development.  The sequence of each stage is predictable, although the time of onset, the length of the stage, and the effects of each stage vary with the person.  Each developmental stage has its own characteristics .
Principles of Growth and Development  Growth and development occur in a cephalocaudal direction, that is, starting at the head and moving to the trunk, the legs, and the feet. This pattern is obvious at birth, when the head of the infant is disproportionately large.
Principles of Growth and Development  Growth and development occur in a proximodistal direction, that is, from the center of the body outward. For example, infants can roll over before they can grasp an object with the thumb and second finger.
Principles of Growth and Development  Development proceeds from simple to complex, or from single acts to integrated acts.  Development becomes increasingly differentiated. Differentiated development begins with a generalized response and progresses to a skilled specific response.
Principles of Growth and Development  Certain stages of growth and development are more critical than others. (the first 10 to 12 weeks after conception are critical).  The pace of growth and development is uneven. growth is greater during infancy than during childhood. Asynchronous (uneven) development is demonstrated by rapid growth of the head during infancy and the extremities at puberty. Growth spurts
Factors Influencing Growth and Development  Genetics  The genetic inheritance of an individual is established at conception which remains unchanged such as eye color and potential height  Temperament  Temperament is the way individuals respond to their external and internal environment. Temperament may persist throughout the life span  Family  The family is the major constant in a child’s life. Families are involved in their children’s physical and psychological wellbeing and development.
Factors Influencing Growth and Development  Nutrition  Adequate nutrition is an essential component of growth and development.  Environment  environmental factors that can influence growth and development include living conditions of the child (e.g., homelessness), socioeconomic status (e.g., poor versus financially  Health  Illness, injury, or congenital conditions can affect growth and development.  Culture  cultural customs, nutritional practices & child-rearing practices can influence a child’s growth and development.
Domains of Growth and Development  Biophysical domain: body systems, motor skills, sensory skills, genetics  Cognitive domain: perception, analyzing, language, thinking, memory, problem solving, creativity, and moral decision  Affective domain : feelings, self-esteem, emotions, identity, self-confidence  Social domain : relationships, communication, roles, social identity, social adaptation  Moral/Spiritual domain : commitments, ethics, faith, purpose in life, integrity, meaning of life, hope.
Stages of Growth and Development  Stage Age Growth & Development Pre-emboryonic 0- 3 wks of gestation Rapid pace of growth and development Emboryonic 4 – 8 wks of gestation Fetal 9 – 40 wks of gestation Neonate Birth to one month Infancy 1 – 12 months Toddlerhood 1-3 years Slow pace of growth and development until puberty Preschool 3-6 years School age 6-12 years
Stages of Growth and Development  Stage Age Adolescence 12-20 years Rapid pace of growth and development from puberty to 15 yrs Young adulthood 20-40 years Decline of growth and development from 16 yrs to 24 yrs Middle adulthood 40-65 years Old adulthood Young old 65-74 years Middle old 75-84 years Old-old 85 and older
Conception of Age  Chronological age : Number of years since birth  Biological age: Age in terms of physical health Psychological age: Adaptive capacity compared to others of the same chronological age Social age: Social roles and expectations relative to chronological age

Editor's Notes

  1. Growth spurts (rapid increase in Growth Rate) There is an optimal time for initiation of experiences or learning Neonatal reflexes must be lost before development can proceed A great deal of skills are learned by practice mastery of developmental tasks is not permanent & do not always correlate with chronologic age
  2. Development becomes increasingly differentiated. Differentiated development begins with a generalized response and progresses to a skilled specific response. For example, an infant’s initial response to a stimulus involves the total body; a 5-year-old child can respond more specifically with laughter or fear. ■ Certain stages of growth and development are more critical than others. It is known, for example, that the first 10 to 12 weeks after conception are critical. The incidence of congenital anomalies as a result of exposure to certain viruses, chemicals, or drugs is greater during this stage than others. ■ The pace of growth and development is uneven. It is known that growth is greater during infancy than during childhood. Asynchronous development is demonstrated by rapid growth of the head during infancy and the extremities at puberty.
