a drug that is important in the regulation of blood pressure.
the process of learning a response or taking up a specific behaviour through association or conditioning.
a type of research concerned with the process of change and what else happens when change occurs. Action research is particularly suitable for organizations or systems requiring improvement or change.
one of the stages proposed by the transtheoretical model of change (TMC) in which a person takes specific actions with the aim of changing unwanted behaviour, bringing positive benefits to well-being.
the early stages of a condition; normally defined as a condition that lasts for less than six months.
pain that lasts for less than six months.
a term used to describe a person’s physical and psychological dependency on an activity, drink or drug, seemingly beyond conscious control. Addiction is said to occur when there is: a strong desire to engage in the particular behaviour (especially when the opportunity to engage in such behaviour is not available); an impaired capacity to control the behaviour; discomfort and/or distress when the behaviour is prevented or ceased; persistence of the behaviour despite clear evidence that it is leading to problems.
theories based on the construct of addiction used to explain alcoholism and other excessive behaviours (e.g., gambling, shopping, drug use, over-eating).
tissue in the body in which fat is stored as an energy reserve and which in excess leads to obesity.
the combination of affluence and influenza and referring to the negative psychological consequences of the restless pursuit of more in the consumerist era.
the capacity to take action in pursuit of intentions and goals.

the bond that forms between parent and child, which can have life-long consequences.
Mary Ainsworth (1970) identified three main attachment styles: secure (type B), insecure avoidant (type A) and insecure ambivalent/resistant (type C). These attachment styles are the result of early interactions with the mother.

Type 1 diabetes mellitus (T1DM) (otherwise known as juvenile diabetes or insulin-dependent diabetes)
a chronic condition in which the pancreas produces little or no insulin, a hormone needed to allow sugar (glucose) to enter cells to produce energy. The far more common Type 2 diabetes occurs when the body becomes resistant to insulin or doesn’t make enough insulin.
Type 2 diabetes mellitus (T2DM) (otherwise known as adult-onset or noninsulin-dependent diabetes)
a chronic condition that affects the way the body metabolizes sugar (glucose), the body’s source of fuel. In Type 2 diabetes, the body either resists the effects of insulin (a hormone that regulates the movement of sugar into cells) or fails to produce enough insulin to maintain a normal glucose level. More common in adults, T2DM increasingly affects children as childhood obesity is becoming more prevalent.

fat that accumulates in organs such as the liver that causes insulin resistance and multiple sclerosis (MS).
