2 Adherence to long-term therapy for chronic illnesses in developed countries averages 50%. In developing countries, the rates are even lower. Noncommunicable diseases (cancer, hypertension, diabetes,etc) Mental disorders, human immunodeficiency virus/acquired immunodeficiency syndrome and tuberculosis, together represented 54% of the burden of all diseases worldwide in 2001 and will exceed 65% worldwide in 2020.

3 La Depressione : definizione
La depressione come fenomeno appare di non facile definizione, in quanto legata indissolubilmente al concetto di umore. L’umore è una dimensione complessa della vita psichica dell’uomo, nella quale confluiscono aspetti emozionali, affettivo/sentimentali, cognitivi, temporali, motivazionali e motori che, se così si può dire, “colora di sé” tutta la vita dell’individuo, costituendo una sorta di griglia percettiva ed elaborativa con cui si dà significato alla realtà. (Vella, Siracusano1994)

4 La Depressione : definizione
Esiste una linea di continuità che collega la depressione sia alla tristezza, esperienza comune e fisiologica, sia al dolore, che rappresenta a sua volta uno dei nulei centrali della depressione. La qualità che fa traghettare dolore e tristezza nella depressione può essere riconosciuta nella loro pervasività, nell’interessare psiche e soma allo stesso modo, nella loro fissità, nel non essere più modificabili dalle situazioni esterne, tristi o liete, nell’intensità del dolore, che tende a congelare vissuti psichici e somatici in un unico blocco privo di spinta evolutiva.

5 Depressione e suicidio
10-15% dei pazienti depressi si suicida I due terzi tra i pazienti depressi hanno idee suicide I pazienti depressi con aspetti psicotici considerano talvolta l’uccisione di persone coinvolte nei loro sistemi deliranti

6 Population projection of US adults with lifetime experience of depressive disorder by age and sex from year 2005 to 2050 (I). In year 2006 the (weighted) prevalence of lifetime experience of depressive disorder was 15.7% among 188,292 respondents aged 18 years or older. Female prevalence was 20.6%, which was about twice as high as the prevalence among males (11%). Heo M,, Murphy CF ET AL.Int J Geriatr Psychiatry May 23. [Epub ahead of print]

7 Population projection of US adults with lifetime experience of depressive disorder by age and sex from year 2005 to 2050 (II). From year , the total number of US adults with depressive disorder will increase from 33.9 million to 45.8 million, a 35% increase. The increase is projected to be greater in the elderly population aged >/= 65 years ( , a 117% increase???) than in the young population aged < 65 years ( , a 25% increase).

9 Gender differences in health status
In industrialized countries males tend to die earlier than females and females tend to have greater longevity but higher rates of morbidity (Okojie, 1994; Stein, 1997; Lewis, 1998) This female advantage is a relatively recent phenomenon and female excess mortality, which defined many western societies prior to the industrial revolution, still pertains in many less developed countries today ( Annandale, 1998)

10 Prevalenza della depressione (National Comorbidity Survey)

11 Prevalence of Depression: Women compared to Men
Major depression is a TREATABLE major public health problem in women Annual Lifetime Women % % Men % % The rate of MD for women rises dramatically above that for men during and after puberty (with two peaks - childbearing years and perimenopausal transition) and then actually falls after menopause

12 Gender Differences in Prevalence of Major Depression
Women: X rate relative to men during ages 15-54 Women are approximately 1.7 times as likely as men to report a lifetime history of MDE. Sex difference begins in early adolescence (age 10) and persists through the mid-50s. The sharp divergence in the 50’s is based upon a small sample size and not thought to be reliable. Sex difference in depression is most pronounces among early adolescents, with the highest relative hazard of first onset (OR=2.3) in the age range This is a consistent finding throughout the world, regardless of how depression is diagnosed. Since women are no more likely than men to be chronically depressed or to have ana acute recurrence in the past year – therefore higher prevalence is due to higher risk of 1st onset. The NCS was a congressionally mandated survey with the specific goal of studying the comorbidity of psychiatric disorders individuals, ages interviewed. Used a supplemental nonresponse survey, with financial incentive, based on previous evidence that survey nonresponders tend to have higher rates of psychiatric d/o. A structured psychiatric interview (DIS-diagnositc interiew schedule – can be administered by trained interviewers who are not clinicians) was administered to a representative US sample. Based on results that respondents underreport stem questions once they recognize that positive responses lead to more detailed questions, they used a life review section before probing any positive stem responses and to facilitate active memory search for lifetime episodes. Anxiety d/o have an approximately 5% 1-yr prevalence form the same study Kessler et al (1993) Journal of Affective Disorders

18 Gender Differences in The Rates of Exposure to Stressful Life Events and Sensitivity to Their Depressogenic Effects Conclusion Women reported more interpersonal whereas Men reported more legal and work -related stressful life events. Most life event categories influenced the risk for major depression similarly in the two sexes The greater prevalence of major depression in women versus men is due neither to differences in the rates of reported stressful life events nor to differential sensitivity to their pathogenic effect. Kendler KS, et al., 2001

19 Gender and the Frequency of Stressful Life Events
Male preponderant: Female preponderant: Housing problems, Loss of confidant, Problems getting along with and crises involving individuals in their proximal network Illness of an individual in their distal network  Job loss, Legal problems, Robbery Work problems No or inconsistent gender difference: financial or marital problems, illness, illness of individual in in one’s proximal network, and problems getting along with and death of an individual in one’s distal network Kendler KS, et al., 2001

26 Postpartum Depression: what it’s not
Postpartum depression has been used as a catchall phrase for many disorders, but it’s important to differentiate it from other postpartum disorders: Maternity Blues Postpartum panic disorder Postpartum obsessive-compulsive disorder Postpartum bipolar II disorder Postpartum posttraumatic stress disorder Postpartum psychosis (Beck, Cheryl Tatano DNSc, CNM, FAAN, American Journal of Nursing, 2006; 106 (5) 40-50)

27 Postpartum Depression: what it is
Postpartum Depression is a major depressive disorder. It strikes about 1 in 10 women. Depressed Mood or Loss of Interest or Pleasure with 5 or more of the following symptoms for at least two week: 1) insomnia or hypersomnia, 2) psychomotor agitation or retardation, 3) fatigue, 4) changes in appetite, 5) feelings of worthlessness or guilt, 6) decreased concentration and suicidality. Although the DSM-IV-TR states that the depressive episode begins within four weeks of birth, many clinicians and researchers agree that this description is too limiting, as it’s thought that postpartum depression can occur up to a year after childbirth.

28 RISK FACTORS Associated With The Development of Postpartum Mood Disorders
Were found to be significant risk factors for postpartum mood disorders: Premenstrual Dysphoric Disorder (PMDD) Mood symptoms during past oral contraceptive use A past history of depression Mood symptoms during the first 2-4 days postpartum Bloch M et al. J Affect Disord. 2005; 88 (1): 9-18.

29 Two recent metaanalyses have identified significant risk factors for Postpartum Depression
Prenatal depression Low self-esteem Difficulties with child care Prenatal anxiety A high stress level A low level of social support Poor marital relationship A history of depression Difficult infant temperament Maternity blues Single marital status Low socioeconomic status Unplanned or unwanted pregnancy Beck, Cheryl Tatano DNSc, CNM, FAAN, American Journal of Nursing, 2006

32 Population projection of US adults with lifetime experience of depressive disorder by age and sex from year 2005 to 2050 (III). CONCLUSIONS By year 2050, approximately 46 million US adults aged 18 years Or older will be diagnosed with a depressive disorder. The increase will be more pronounced in adults aged 65 or older. Prevention, detection, and treatment of depressive disorders might attenuate the magnitude of this estimate. Heo M,, Murphy CF ET AL.Int J Geriatr Psychiatry May 23. [Epub ahead of print]
