UNIT 2 AOS 1: PRENATAL DEVELOPMENT
Transcript of UNIT 2 AOS 1: PRENATAL DEVELOPMENT
PRENATAL HEALTH AND INDIVIDUAL DEVELOPMENT
DETERMINANTS OF PRENATAL DEVELOPMENT
BROSHURE PART 1:
Be able to describe
one key prenatal health
issue and identify
the risk of the condition chosen
Describe and explain factors that affect the health and individual human development during the prenatal stage
HEALTH STATUS OF AUSTRALIA'S PREGNANT WOMEN AND UNBORN BABIES
Deaths of babies before birth (over 20 weeks gestation) and up to 28 days after birth
Describe the characteristics of physical development from conception to birth
Interpret data on health status of pregnant women and unborn babies
Explain the determinants of health and individual human development and their impact during the prenatal stage of the lifespan
Describe a specific health issue affecting the prenatal stage of the lifespan and identify determinants that act as risk/protecive factors
Draw conclusions about programs to optimise prenatal health and development
(3 - 8 Weeks)
(9 - 40 Weeks)
KEY HEALTH ISSUES
UNIT 2 AOS 1
PRENATAL HEALTH AND DEVELOPMENT
"Explains the direction and and process of general human development"
PRINCIPLES OF DEVELOPMENT
2. DEVELOPMENT IS CONTINUAL
Development starts with conception and ends with death.
1. DEVELOPMENT OCCURS IN A PREDICTABLE AND ORDERLY WAY
You can generally predict when milestones SHOULD occur.
Can you think of any examples?
3. INDIVIDUAL VARIATION IN TIMING OF DEVELOPMENT
Hormones, genetics, family interactions, nutrition, physical activity and health can influence rate and timing of development
4. DEVELOPMENT FOLLOWS PREDICTABLE PATTERNS
Development follows patterns that are observable in everyone.
5. DEVELOPMENT PROCEEDS FROM SIMPLE TO COMPLEX
Child will learn to crawl before walking
"Development from head downwards"
"Development from core outwards - towards extremities"
Commences once fertilisation occurs and is the period of most rapid growth
Fertilisation: "Sperm enters an ovum (egg) to form a complete cell known as a zygote"
PHYSICAL DEVELOPMENT PROCESS....
(Begins at fertilsation and ends with implantation)
1. FERTILISATION occurs creating a ZYGOTE which travels down the fallopian tubes
2. Three days after fertilsiation the travelling Zygote forms into a MORULA (8 + cells).
3. Five days after fertilisation Morula transforms to include an inner cell mass (BLASTOCYST)
and outer cell mass (PLACENTA).
5. When BLASTOCYST reaches the uterus, it implants into the ENDOMETRIUM and is now
known as an EMBRYO.
Zygote: "Newly formed cell"
Morula: "Spherical shaped zygote made up of 8+ cells"
Blastocyst: "Inner cell mass that eventually becomes the embryo"
Endometrium: "Lining of the uterus where the embryo embeds itself"
PHYSICAL DEVELOPMENT PROCESS...
(Begins at implementation until approximately the 8th week)
1. Cell differentiation occurs (cells take up different roles).
2. PLACENTA develops and allows for exchange of substances.
3. Internal/External systems and organs are formed.
4. Brain and Spinal cord almost complete.
5. Internal sex organs begin to form.
6. Head/Neck still account for 1/2 embryo length and brain accounts for 1/2 its
body weight (Cephlacaudal development)
6. Limbs begin as buds and continue to grow out (Proximodistal development).
7. Teratogens are extremely influential during this stage of development.
PHYSICAL DEVELOPMENT PROCESS..
1. Rapid growth occurs (Foetus begins at a few cm and ends up about 50cm).
2. Organs and system functioning increases
3. Sex organs continue to develop and sex can be determined after 15 weeks.
4. Reflexes (E.g. grasping) are highly responsive and continue to develop
5. Foetus shows a breathing movement, but lungs are filled with amniotic fluid.
6. Bones begin to harden and ossify.
7. Senses begin to function and react.
8. PLACENTA is fully developed at 14 weeks
Allows exchange of substances (oxygen, nutrients, urine, carbon dioxide) between mother and foetus
Connected to foetus via the umbilical cord which is made up of 2 arteries and 1 vein
Umbilical vein - supplies nutrient rich oxygenated blod to the plancenta
Umbilical ateries return oxygen and nutrient depleted blood to placenta
Produces progesterone which assists with maintaining pregnancy
PARENTAL SMOKING DURING PREGNANCY
ALCOHOL USE DURING PREGNANCY
DRUG USE DURING PREGNANCY
CHOOSE ONE BEHAVIOURAL DETERMINANT AND IDENTIFY HOW IT IMPACTS HEALTH AND OR DEVELOPMENT
CHOOSE ONE BIOLOGICAL DETERMINANT AND IDENTIFY HOW IT IMPACTS HEALTH AND OR DEVELOPMENT
Normally goes undetected and includes conditions such as Neural Tube Defects and Down Syndrome
Death of a woman while pregnant or within 42 days of termination of pregnancy, or giving birth
MATERNAL MORTALITY RATE (/100,000 BIRTHS)
a) Identify a trend of the
maternal mortality ratio in
NEURAL TUBE DEFCT TRENDS (/10,000 BIRTHS)
a) Identify a trend in relation to
the prevalence of NTDs in
b) Why has this trend occured
a) Describe a trend evident in the graph above
b) What conclusion can be drawn relating to the age of
the mother and perinatal mortality rates
a) Describe a trend evident in the graph above
Read Pg. 183 - 184 and describe one of Neural Tube Defects or Down Syndrome.
Common conditions during pregnancy include gestational diabetes, mental health issues, Pre-Eclampsia, Ectopic Pregnancy
Read Pg. 185-187 and describe one of the maternal conditions outlined using Voki
TOBACCO SMOKE IN HOME
ACCESS TO HEALTHCARE
CHOOSE ONE PHYSICAL ENVIRONMENT DETERMINANT AND IDENTIFY HOW IT IMPACTS HEALTH AND OR DEVELOPMENT
ACCESS TO HEALTHCARE
CHOOSE ONE SOCIAL DETERMINANT AND IDENTIFY HOW IT IMPACTS HEALTH AND OR DEVELOPMENT
LOW BIRTH WEIGHT
FOETAL ALCOHOL SYNDROME
STRATEGIES/PROGRAMS TO PROMOTE PRENATAL HEALTH/DEVELOPMENT
Describe what medicare provide for the pregnant women and their unborn child?
HEALTHY MOTHERS HEALTHY BABIES
BROHURE PART 2:
In your broshure advertise 1 federal/1 state/1 local government/1 community program available to promote prenatal health and development.
Also include a range of personal strategies that a mother could incorporate into her lifestyle during the pregnancy period.
Maintain a healthy body weight
Regular prenatal checks
Attending antenatal education classes
Up to date with vaccinations
Reducing stress levels
MATERNAL AND CHILD HEALTH CENTRES
