Body weight
 Can have a range of impacts on an individual.
 Can be a risk factor for many other health conditions
like Hypertension, high blood cholesterol and
impaired glucose regulation.
Body weight
 Obesity is linked to:
 Cardiovascular disease
 Some cancers (e.g. Colorectal cancer)
 Respiratory problems
 Arthritis
 Self esteem issues
 Social exclusion
Blood pressure

Blood pressure
 Factors contributing to Hypertension (high blood
pressure) are:





Stress
Smoking
Excessive alcohol consumption
Genetic predisposition
Poor diet (high sodium intake increases BP)
Cholesterol

 Cholesterol is found in animal products.
 LDL cholesterol= Bad (Low –density lipoprotein)
 HDL cholesterol= Good  (high density lipoprotein)
 Too much LDL= build up in artery walls, causing
atherosclerosis.
Cholesterol
 Risk factors for High blood cholesterol include:
 Excessive alcohol intake
 Smoking
 Diet high in saturated fat and or Trans fat
 Lack of exercise
 Genetic predisposition
Impaired Glucose regulation
 When carbohydrates are consumed, they are turned
into glucose in the blood stream.
 Insulin is released from the pancreas when glucose
levels rise to allow the glucose to travel from the blood
stream to cells to be used for energy.
 If blood glucose levels are high, then insulin levels are
high also.
Impaired glucose regulation
 If this occurs over a long period of time, then the body
can become resistant to the action of insulin.
 Insulin resistance impairs glucose regulation which is a
risk factor for type 2 diabetes.

Can occur as a result of:
Genetic predisposition
Stress
Pregnancy
Lack of exercise
Smoking
Being overweight
Diet high in triglycerides
Excessive alcohol consumption
Low LDL cholesterol
High blood pressure
Birth Weight
 Is related to health outcomes directly after birth and
later in life.
 Babies may suffer from:


Underdeveloped immune system
Premature death and significant disabilities
Birth weight
 Adults may suffer from:
High BP
 Type 2 diabetes
 CVD
CAUSES OF LOW BIRTH WEIGHT:
 Premature birth
 Age of mother- young mothers (under 15 yrs), older mothers
(over 45 yrs)
 Mother’s nutritional status
 Smoking, excessive alcohol consumption and drug use during
pregnancy
 Illness of mother during pregnancy.
