Explain how blood cholesterol contributes to the risk of cardiovascular disease
Blood cholesterol becomes a health issue when there is too much of it in the blood. High blood cholesterol levels, particularly LDLs are one of the three risk factors for heart disease (the other two are tobacco smoking and high blood pressure). The liver is where the processing of cholesterol occurs. When saturated fats are consumed, the cholesterol that is not processed by the liver is returned to the bloodstream. If there is too much of LDL cholesterol in the blood, it can build up into fatty deposits on the arterial walls. This build-up of fatty deposit causes a narrowing of the arteries (atherosclerosis), which may eventually become blocked and cause a heart attack or stroke.
Explain how blood pressure contributes to the risk of cardiovascular disease
Blood pressure can increase with exercise or exertion. Elevated blood pressure is a concern when the pressure remains high while at rest because the heart is being overworked and the arteries have increased stress on the arterial walls. This can accelerate the depositing of fatty plaques on the arterial walls, a condition called atherosclerosis. Atherosclerosis contributes to other illnesses such as coronary heart disease and stroke.
What is a cardiovascular disease?
Cardiovascular disease is a collective term used to describe conditions that are associated with the heart and the blood vessels. This term is used to describe conditions such as coronary heart diease, heart failure, cardio myopathy, congenital heart disease.
What is cancer?
Cancer is disease of the cells, which are the body’s building basic building blocks. Cancer cells are when abnormal cells grow in an uncontrolled way. These abnormal cells can damage or invade to the surrounding tissues or spread to other parts of the body causing further problems
Outline a government, community or personal strategy designed to promote health and individual human development of adults with this issue (cancer)
Daffodil Day—is a fundraiser for cancer research, prevention and support services. Daffodil Day is held on the 28th of august every year.
What is burden of disease?
Burden of disease is a health indicator which combines mortality data with morbidity data so that conditions that contribute differently to illness and death can be compared. Measured in DALY—disabiity adjusted life year.
Identify two examples of each physical and social development of youth
Physical development:
1. Refnement of gross and fine motor skills
2. reproductive organs become fully fuctional
Social development:
1. Ability to change behaviour according to situation
2. Increase in conflict with parents
what is determinant?
Determiants refers to the factors that raise or lower the levels of health in an individual or population. Determnants of health expain or predict health in trends and why some groups have better or worse health than others.
What is incidence?
Incidence refers to the number (or rates) of new conditions or disease in a popualtion during a given period (usually 12 months).
What is prevalence?
Pervalence refers to the number or proportion of cases of a particular disease or condition present in a population at a given time.
What is mortality?
Mortality refers to death in a population. The mortality rate is therefore an indication of how many deaths occured in a population in a given period of time for a specific cause/all causes.
What is morbidity?
Morbidity refers to ill-health–including disability, injury and disease–in an individual and the level of ill-health in a population. So the mobidity rate refers to the rate of ill-health in a population in a given period of time.
