  1. CHAPTER 8Life Span Development

  2. Health Promotion Across the Life Span • Life Expectancy • This is the average number of years an individual will probably live. • Life expectancy in the United States at the beginning of the twentieth century was 47.3 years. • Today, average life expectancy at birth in the United States is 77 years. • There are currently 18 countries that have a life expectancy greater than that of the United States. • Females outlive males by an average of 6 years.

  3. Health Promotion Across the Life Span • Life Expectancy (continued) • Those in households with incomes of greater than $25,000 live 3 to 7 years longer depending on gender and race than do those in households with individual incomes of less than $10,000. • Infant Mortality • This is the number of deaths before the first year of life. • The infant mortality rate for African-American infants is more than double that of white infants.

  4. Health Promotion Across the Life Span • Development • Begins at conception and ends with death • The study of life span development is the study of how and why persons change over time, as well as how they remain the same. • The eight stages of life span development • Infancy, toddler, preschool, school age, adolescence, early adulthood, middle adulthood, and late adulthood

  5. Growth and Development • Growth • Refers to an increase in size of the whole or its parts • Development • Refers to function or the gradual process of change and differentiation from simple to complex • Cephalocaudal • Growth and development that proceed from the head toward the feet • Proximodistal • Growth and development that proceed from the center toward the outside

  6. Growth and Development • Patterns of Growth • Growth patterns appear to be genetically controlled. • Nutrition, heredity, and environment play an important role in the patterns. • The blueprint for all inherited traits is contained in the chromosomes. • At conception, the individual is endowed with a complex set of biologic potentials involving characteristics such as height and skin, hair, and eye color.

  7. Growth and Development • The Beginnings • Development begins with conception. • After fertilization, the zygote has 23 pairs of chromosomes, for a total of 46 chromosomes. • One of each pair has been contributed by the mother and one by the father. • Teratogen • Any substance, an agent, or a process that interferes with normal prenatal development, causing the formation of one or more developmental abnormalities in the fetus

  8. The Family • The family is the basic unit of society. • Families are composed of two or more people who are united by marriage, blood, adoption, emotional bonds, and/or social roles. • The individuals of the family usually share ties that often last a lifetime. • Family is the first socializing agent for teaching children society’s expectations and limitations • Part of socialization • Family is responsible for ensuring that the child receives a formal education

  9. The Family • Family is responsible for instilling morals, values, and ideals into children • The birth of a baby and the death of a family member are happenings that create the need to rearrange family roles and structures • Types of families • Nuclear, extended, single-parent, blended, social contract family and cohabitation, homosexual, adoptive, and foster

  10. The Family • Types of Families • Nuclear family • Biological parents and their offspring • Thought of as traditional family • Sex-based roles assigned to its members • Consists of a husband and wife with or without children living in independent household setting • Both parents work and share equally in financial support, roles, and responsibilities • Extended family • Consist of biological parents, children, grandparent, grandchildren, aunts, uncles, other family members • Sharing of support, roles, and responsibilities • Basic family group in many societies

  12. The Family • Types of Families • Social contract family and cohabitation • Involves unmarried couple living together and sharing roles and responsibilities • Homosexual family • Group made up of same-sex couple • Homosexual adults form family units • Their members share bonds of emotional commitment and roles of child rearing • Consists of either natural children or adopted or foster children • Each family type has common parenting concerns and responsibilities

  35. Stages of Growth and Development • Infancy: 1 to 12 Months • Dentition • Teething begins at about 5 to 6 months • Signs of teethingirritability, edematous red gums, excessive drooling, change in stools  usually begin 3 to 4 weeks before appearance of tooth. • Oral hygiene consists of offering sips of clear water and wiping and massaging the infant’s gums. • Tooth brushing should begin after the first teeth appear.

  36. Stages of Growth and Development • Infancy: 1 to 12 Months • Psychosocial Development • Basic trust versus mistrust • Cognitive and Intellectual Development • Infant uses senses to learn about self and the environment. • Infant learns through exploration of objects and events and through interaction. • Infants are in the sensorimotor stage of cognitive development; knowledge occurs primarily through sensory impressions and motor activities.

  37. Figure 8-3 (From Hockenberry-Eaton, M.J., Wilson, D., Winkelstein, M.L., Kline, M.D. [2003]. Wong’s nursing care of infants and children. [7th ed.]. St. Louis: Mosby.) Nine-month-old infant enjoying own image in a mirror.

  38. Stages of Growth and Development • Infancy: 1 to 12 Months • Communication and Language • During infancy, the unique ability of the brain to sort out basic sounds and to extract from sentences becomes apparent. • Infants will not speak spontaneously; the environment must provide a means for them to acquire these skills. • The rate of speech development varies from child to child and is directly related to neurologic competence and intellectual development.

  39. Stages of Growth and Development • Infancy: 1 to 12 Months • Nutrition • Both human breast milk and commercially prepared formula are available to meet the nutritional needs of the infant. • Foods that should be avoided in the first 6 months of life are citrus fruits, egg whites, wheat flour  all frequently identified as allergy-producing substances. • Rules for solid foods: introduce only one new food at a time; introduce cereals first, then fruits and vegetables, and meat last.

  40. Stages of Growth and Development • Infancy: 1 to 12 Months • Sleep, Play Activity, and Safety • Newborns and infants sleep 18 of 24 hours. • Toward the end of the first 3 months, definite sleep patterns emerge. • By the end of the first year, the infant will sleep 12 hours at night and take one nap during the day. • Play is important for learning. • Accidents are the leading cause of injury and death in infants and young children.

  41. Stages of Growth and Development • Toddler: 1 to 3 Years • Physical Characteristics • Rate of growth is slower in the toddler than in infancy. • In the beginning of this stage, the toddler’s body proportions result in a top-heavy appearance, but by the end they have a more proportionate body appearance. • Toddlers have an exaggerated lumbar lordosis and protruding abdomen. • By 2.5 years, all 20 deciduous teeth are present.

  42. Stages of Growth and Development • Toddler: 1 to 3 Years • Vital Signs • Pulse: 90-100 beats per minute • Blood pressure: 100-80/64 • Temperature: 98-100º F • Respirations: 20-30 breaths per minute • Neuromuscular Development • Walking, climbing, hopping, running, pulling, holding on tight skills • Scribble and copy a circle

  48. Figure 8-8 (From Mahan, L.K., Escott-Stump, S. [2004]. Krause’s food, nutrition, and diet therapy. [11th ed.]. Philadelphia: Saunders.) Milk and other dairy products supply the toddler with the calcium and vitamin D for growing bones.

  49. Stages of Growth and Development • Toddler: 1 to 3 Years • Sleep, Play Activity, and Safety • Toddlers expend a high level of energy in daily growing, playing, and exploring. • They require 12 hours of sleep each night plus a daytime nap. • Parallel play: play alongside of, but not with, peers • Running, jumping, and climbing help develop their growing bones and muscles. • More than half of all childhood deaths are caused by accidents, many of which are motor vehicle accidents.
