Definition of health (WHO)

"A state of complete physical, mental and social wellbeing & not merely the absence of disease or infirmity"

Examples of physical development

- Change in body shape over lifespan - Learning to walk or crawl - Sexual maturation of the body that occurs at puberty

Physical characteristics of development during youth

- Change is rapid - The size of the bones and muscles - Taking on adult body proportions - Changes in weight and height

Interrelationships between health and development

- Described as a complex web - Need optimal health and optimal development both need each other in order to be optimal.

Example of good social health

Social characteristics of development during youth

- Forming social relationships - Extremely important and one of the most important aspect of youth social development - Establishing an 'identity' and being accepted within a peer group - Gain self esteem - Strongly connected with self-esteem and confidence

Asthma: Risk factors

- Genes - Although doctors don't know what causes asthma it is know to run in families - Behavioural - Choosing to exercise in the cold (Going near triggers) - Environmental - Living near areas with lots of pollen

Examples of social development

- Going to school and making friends - Complex behaviour such as using language

Intellectual characteristics of development during youth

- Individual develops the ability to think in broader terms. - Significant changes in the way youth are taught compared to children - Expected to be more independent about their learning and take more responsibility - Independence not in academics - Adolescents are more likely to think independently and question their parents judgementhe decisions they make, such as what to spend their money on, what friends to have or which subjects they should study in school. - Decision making time - Establish their own identity - Progress to a more adult way of thinking

Asthma: Protective factors

- Keeping away from triggers - Choosing healthier foods - Seeking medical advise when needed

Examples of emotional development

Example of good physical health

- Physical capacity (energy, strength and coordination) to perform ordinary tasks - Resistance or susceptibility to disease

Examples of intellectual development

- Speaking first words and establishment of language skills - Improving memory of objects and facts - Gaining employment

Example of good mental health

- Understanding and expressing one's emotions, and being aware of the feelings of others - Having positive self-esteem and self-confidence

Two limitations of the WHO definition of health.

1. It is very hard to achieve a "complete" wellbeing in all mental, social and physical health 2. It does not cover other aspects such as shelter and income and without these things it is hard to be completely healthy

Health status (WHO)

A description and/or measurement of the health of an individual or population at a particular point in time against identifiable standards, usually by reference to health indicators.

Disease

A physical or mental disturbance involving symptoms, dysfunction or tissues damage.

Illness

A state of feeling unwell.

Macronutrients

Are nutrients that the body requires in large quantities, namely proteins, carbohydrates, fats and water.

Asthma: Incidence, prevalence and changes over time (trends)

Asthma has relatively high rates of asthma, especially when compared to other countries. In total over 2 million Australians have asthma including 1 in 10 adults, 1 in 8 teenagers (youth) and 1 in 7 primary aged children. The burden of disease is also quite large, asthma accounted for 7995 DALY's or 4% of the total burden of disease for young Australians aged 15-24 years. For males the time that asthma is most present is between the ages of 10 and 14, and for females it is between the ages of 20-24. Asthma levels have remained relatively stable for adults yet they have decreased in children. It is also known that the prevalence for asthma in indigenous people is considerably higher than the prevalence for all young Australians.

Asthma: Impact on physical health

Asthma is a chronic illness it will continuously affect the health of the patients lungs, which in turn affects their physical health as they may find it harder to participate in sport.

Why is asthma an issue for youth?

Asthma is an issue for youth because it can restrict their physical, social, emotional and intellectual development, and as they are already going through all these changes asthma may seem like a low priority to them when in some cases it isn't.

What is energy needed for?

Basal metabolism, physical activity and growth.

What are the determinants of health?

Biological, Behavioural, Physical Environment, Social environment (Family and Community)

What is the preferred source of energy?

Changes that occur to your body over time.

Food source of fats

Dairy, nuts, olive oil, avocadoes and oily fish

Mortality

Data on death and its causes.

Risk factor

Determinants of health that increase the chances of ill health.

Protective factor

Determinants of health that increase the changes of good health.

DALY

Disability Adjusted Life Year. Calculate which conditions have the greatest effect on health. One DALY is one year of 'healthy life' lost due to injury or disease, they also take into account the quality of life lost from living with a disease or injury. DALY = YLL + YLD

Secondary sexual characteristics

Distinguish males from females and indicate a level of physical maturation.

Asthma: Impact on emotional development

Emotionally most people will learn to deal with the illness over time but for those who feel that they "miss out" on too much, it can even lead to diseases such as depression or anxiety.

Biological determinants

Factors that depend on biology such as: - Genes - Body weight - Hormones

Social Environment determinants

Family and community, relating to family friends and social interactions. For example, family cohesion, socioeconomic status of parents, community participation and access to education.

Examples of primary sexual characteristics

Female - Cervix, uterus, vagina, fallopian tubes and ovaries. Male - Penis, prostate, testicles and scrotum

Examples of secondary sexual characteristics

Female - Enlargement of breasts, widening of hips, growth of underarm and pubic hair. Male - Deepening of the voice, broadening of the shoulders, growth of body hair and increase in muscle mass.

Asthma: Community strategies

For example the ACAP, which stands for the Asthma Child and Adolescent Program, provides teachers and students with the information that they need to learn about asthma and respond quickly in an emergency. There is also training sessions available for schools and preschools, that helps explain the needs of children with asthma and how to deal with it.

Asthma: Impact on social health

Friends or peers are very likely to comment on this, they would tease them about being "unfit" or that they are "making it up" and it can often be quite hurtful as most youth want to gain approval from their peers. This can lead to an unhealthy social life, and they will be less likely to want to go to school or meet up with their friends. This in turn can affect their mental health, as they will likely be feeling left out or not wanted. This can put a lot of stress on teenagers as gaining approval can often seem very important.

Asthma: Impact on Physical development

Physically the asthma itself does not cause any long-term damage to the body, however the medication taken could have any type of affect. For example, if a child is regularly using their inhaler or asthma medication containing a steroid then it can have an affect on their overall height. The steroids in the drug cause the person to stop growing before they reach their full potential height.
