Generalized anxiety disorder:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Theorists share a common premise: Conflict, whether intrapsychic, sociopersonal, or interpersonal, promotes an anxiety state.
Generalized anxiety disorder has a 1-year prevalence range from 3% to 8%. It’s more common in women than in men, and half of all cases begin in childhood or adolescence.

Major depression:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The multiple causes of depression aren’t completely understood. Current research suggests possible genetic, familial, biochemical, physical, psychological, and social causes. Psychological causes (the focus of many nursing interventions) may include feelings of helplessness and vulnerability, anger, hopelessness and pessimism, and low self-esteem. They may be related to abnormal character and behavior patterns and troubled personal relationships. In many cases, the history identifies a specific personal loss or severe stressor that probably interacts with the person’s predisposition to provoke major depression.
Depression may be secondary to a specific medical condition — for example, metabolic disturbances, such as hypoxia and hypercalcemia; endocrine disorders, such as diabetes and Cushing’s syndrome; neurologic diseases, such as Parkinson’s and Alzheimer’s diseases; cancer (especially of the pancreas); viral and bacterial infections, such as influenza and pneumonia; cardiovascular disorders, such as heart failure; pulmonary disorders, such as chronic obstructive lung disease; musculoskeletal disorders, such as degenerative arthritis; GI disorders, such as irritable bowel syndrome; genitourinary problems, such as incontinence; collagen vascular diseases, such as lupus; and anemias.
Drugs prescribed for medical and psychiatric conditions as well as many commonly abused substances can also cause depression. Examples include antihypertensives, psychotropics, opioid and nonopioid analgesics, antiparkinsonian drugs, numerous cardiovascular medications, oral antidiabetics, antimicrobials, steroids, chemotherapeutic agents, cimetidine, and alcohol. Depression occurs in up to 18 million Americans, affecting all racial, ethnic, and socioeconomic groups. It affects both sexes, but is more common in women.

About prevalence and incidence statistics:
The term 'prevalence' of Anxiety Disorders usually refers to the estimated population
of people who are managing Anxiety Disorders at any given time.
The term 'incidence' of Anxiety Disorders refers to the annual diagnosis rate,
or the number of new cases of Anxiety Disorders diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
For more information see about prevalence and incidence statistics.
