Biological factors
Relates to the structure of the cells, tissues and systems of the body and how adequately they function. There is a range of biological factors and although many are the outcome of various sociocultural and environment factors, there is often a genetic influence that cannot be controlled. In some cases examples of biological factors are also examples of physical health and well-being
Body weight
Shifts towards Energy- dense diets and decreasing physical activity have contributed to increases in rates of over weight and obesity.
Genetics may play a role but the main cause is an imbalance between energy consumed and energy expended.
Body weight cont..
body mass index
An index of weight for height, is used to classify people as over weight and obese.
It is defined as the weight in kilograms divided by the square of the height in meters
A BMI of 25-29.9 indicated overweight and 30 and over indicates obesity
BMI= wight(kg)

Height(m2)
Body cont..
Waist circumference
Is increasingly being used as an indicator of body weight
A measurement greater than 88cm in woman and 102cm in men indicates a higher risk
Blood pressure
Is normally reported as the systolic figure over the diastolic figure: 120/80 indicates normal blood pressure
A person with high blood pressure has hypertension
This many mean that their heart and kidneys (which regulate blood pressure and filter the blood) have to work harder and blood flow may be restricted
Hypertension risk factors (high blood pressure)
Stress, smoking, excess alcohol consumption, genetic predisposition and poor diet
What is cholesterol
It is a type of fat required for numerous functions in the body
The body creates cholesterol in the liver however, most people consume additional cholesterol from animal products like full cream milk and fatty cuts of meat
What are the types of cholesterol
Low density lipoprotein also known as bad cholesterol and high density also known as good cholesterol
When there is too much low density lipoprotein in the blood it tend to be deposited in the walls of the blood vessels giving the blood less room to travel to the cells
Blood cholesterol cont
If too much cholesterol is produced the risk of cardiovascular disease (such a stroke and coronary heart disease) increases
Atherosclerosis
The build up of plaque, caused by excess cholesterol resulting in gardening and loss of elasticity of blood vessels
Impaired Glucose regulation
If blood glucose levels are consistently high, then the levels of insulin are also high
If this occurs over a long period of time, the cells can become resistant to the action of insulin, preventing glucose from being absorbed
What can impaired glucose regulation occur as a result of
Genetic predisposition
Smoking
Being over weight
Birth weight
Babies born with a low birth weight (under 2.5 kgs) are more likely to have an under developed immune system, making them more susceptible to infections. They are also likely to have increased health concerns later in life.
Genetics
Control many aspects of life that indulgence health and wellbeing, such as sex, body type, hormone production, predisposition to disease and aspects of personality
Genetic predisposition
Genetics can also influence how likely someone is to develop a certain condition or disease. This doesn’t mean that a person with a predisposition to a certain condition will necessarily develop it, but they are at an increased risk
What is oestrogen
A key hormone needed for the regulation of the menstrual cycle in woman. Oestrogen also helps to maintain bone density by keeping the bones strong. When a woman enter menopause, the levels of oestrogen decline increasing the risk of osteoporosis
What is testosterone
Increases the likelihood of risk taking which contributes to ill health. When testosterone levels drop in men (after about age 40) there can be numerous systems, including loss of sex drive, fatigue and depression
Sociocultural factors
The social and cultural conditions into which people are born, grow, live, work and age. These conditions include socioeconomic status, social connections, family and cultural influences, food security, early life experiences, and access to affordable, culturally appropriate health care
Biological factors include
Genetics (hormones, predisposition to disease) Body weight Blood cholesterol levels Blood pressure Blood glucose regulation Birth weight
Sociocultural factors include
Social economic status (income, employment status, education and occupation)
Level of education
Employment status
Social networks (family, peers and community)
Social isolation
Housing issues (over crowding and homelessness)
Access to health information and health care
Early like experienced
Good security
Social economic status
Involves inclme + occupation + education = socioeconomic status
Generally wealthier people are healthier people
Physical and mental health and well-being is strongly associated
People who are more socioeconomically disadvantaged are
Less likely to take notice of health promotion messages
More likely to smoke and be obese due to poor nutrition
More likely to experience over crowded housing condition
Access to health care (advancement to medical knowledge)
Decreased mortality rates and an increased life expectancy
Decreased morbidity
Reduced rate of low birth weight babies
Barriers that limit access to health care and what it can lead too
Cultural, financial
Can lead to treatable conditions go undiagnosed
Higher mortality from treatable conditions
Premature death
Employment status - employment
Can provide a sense of identity, social status and purpose in life
Is related to health problems may relate to injuries sustained at work, especially in the physical task some jobs require
Under employment
Puts financial strain on individuals and families as well as poor mental health outcomes: stress and anxiety, loss of identity, poor self esteem and social isolation
Has a significant impact on physical and mental health. Those who are underemployed experience a higher rates of premature death such as suicide, lung cancer and cardio vascular disease and substance abuse
Social exclusion definition
The segregation that people experience if they are no adequate toy participating in the society in which they live
Causes and results of social exclusion include
Mental illness Disability Family breakdown Homelessness Lack of education and skills Low income Relative poverty
Social isolation def
Refers to individuals who are not in regular contact with others
Cultural influences include …
Impact of Health status, gender stereotypes, food beliefs and diet, attitudes and beliefs
Food security def
The state in which all persons obtain nutritionally adequate, culturally appropriate, safe food regularly through local non- emergency sources
Early life experiences
Tobacco, alcohol and drug use and maternal nutrition And exposure to certain chemicals, bacteria and viruses during pregnancy can all have significant implants on the individual after birth and into adulthood. Cam contributes to CV and diabetes in later life
Abuse or neglect affects brain function and development and contributes to emotional behavioural problems later in life.
