Goals and Objectives
• We aim to discuss cultural factors impacting
on the diagnosis and treatment of depression
in Hispanics.
• We will show results of recent studies on
cultural barriers to diagnosis and treatment.
• We will present emerging genetic data on
prediction of antidepressant treatment
response in Mexican Americans.
• Largest minority group in the United States.
• 1 in 12 Americans are Mexican-American.
• Buying power of Mexican-Americans the same as that of
all of Mexico.
• Limited number of trials and studies on Hispanic Health
Chronic stress, early loss, deprivation are risk factors for depression
Common in Hispanic immigrants
Are Hispanic immigrants at higher risk for mental illness?
How do Hispanics deal with mental illness from a cultural perspective?
How do Hispanics respond to medication?
What are the rates of diagnosis, effective treatments and adequate follow
up in Hispanics?
The Concept of “Hispanic”
Is it a language issue? What about Portuguese, or Mayan, or Aztec?
A common heritage? Which heritage?
An ethnicity?
Anyone could be Hispanic, from a person of pure northern European descent, to
African, or Asian backgrounds.
The majority are of Iberic peninsula heritage with different admixtures of native
American and African backgrounds.
Iberic peninsula itself is highly heterogeneous: Melting pot of Celtic, Latin, Basque,
Muslim, Jewish, Viking, and Germanic backgrounds.
Native America is highly heterogeneous, multitudes of languages, cultures and
backgrounds that came in separate waves from Asia and evolved differently in
different places.
Africans taken to America came over hundreds of years from myriad locations with
vastly different cultures and backgrounds.
Bottomline: The admixtures of highly heterogeneous groups can only be highly
heterogeneous itself - Yet there is something in common. What is it?
Challenges in Diagnosis and
Treatment of Depression in
Diagnosing Hispanics - Points
to Consider
Is there a language barrier?
Is there a cultural barrier?
How are the symptoms of anxiety expressed in this culture?
How are the symptoms of depression expressed in this culture?
How are the symptoms of psychosis expressed in the culture?
Are there culturally-congruent non-reality based experiences?
How are those differentiated from psychiatric symptoms, particularly prodomal
Do people seek early diagnosis or “hide” the problem?
Do you tell patients their diagnosis?
What about their families?
Example: “You (your son) has a major depression and is at a high risk for killing
Treating Hispanics - Points to
Do patients express psychological symptoms somatically?
Does the patient accept the diagnosis and the need for treatment?
Will the patient accept the type of treatment?
Can they afford the treatment?
Do they understand they need to take medication way after they feel better?
Do they understand they will deteriorate if they stop taking meds on their own?
Do you trust what the patient tells you?
Does the patient trust what you tell him/her?
Will the patient accept a drug with a potential deleterious effect regarding sexual
Will the patient tell you about sexual side effects?
Will men tell you what can be culturally perceived as weakness - “women’s stuff”:
• Sadness
• Crying spells
• Inadequacy
• Guilt
• Decreased libido
• Suicidality
Trauma, Domestic and Sexual
Violence: Documented Risk
Factors for Depression
Is it disclosed?
What about non-traditional: women abusing men?
Will intervention worsen what can be a very precarious and hard
immigrant life?
When do you try to help?
When do you involve the legal system?
When and why do you keep the legal system aside?
Are there children in the picture?
What do you when you “know” it is happening but they will all
deny it?
Is it appropriate to call Child Protective Services on a “hunch”?
If you dismantle a family structure, albeit problematic, what do
you offer to replace it?
The Stigma of Antidepressant
Treatment in Hispanics
• Data generated from six focus groups of Latino outpatients receiving
antidepressants (N=30).
• Perceptions of stigma - related to both the diagnosis of depression and
use of antidepressant medication.
• Antidepressant use - seen as implying more severe illness, weakness
or failure to cope with problems, and being under the effects of a drug.
• Reports of stigma - related to social consequences.
• Stigma - prominent concern among Latinos receiving antidepressants
• Stigma often affected adherence.
• Culture - important role in the communication of stigma and its
associated complications.
Interian A, Martinez IE, Guarnaccia PJ, Vega WA, Escobar JI. Psychiatr Serv. 2007;58:1591-4.
• A qualitative analysis of the perception of stigma among Latinos receiving antidepressants.
Stigma for Seeking Mental Health
Treatment in Latinas
• Study examined the extent to which stigma-related concerns about mental health
care account for the underuse of mental health services among low-income
immigrant and U.S.-born black and Latina women.
• Participants: 15,383 low-income women screened for depression in county
entitlement services asked about barriers to care, stigma-related concerns, and
whether they wanted or were getting mental health care.
• Compared with U.S.-born white women, immigrant African women (OR=.18,
p<.001), immigrant Caribbean women, U.S.-born black women, and U.S.-born
Latinas were less likely to want treatment.
• Conversely, compared with U.S.-born white women, immigrant Latinas were more
likely to want treatment.
• Stigma related to antidepressant treatment - greater in US-born
than immigrant Latinas.
• Nadeem E, Lange JM, Edge D, Fongwa M, Belin T, Miranda J. Psychiatr Serv. 2007;58:1547-1554.
Does stigma keep poor young immigrant and U.S.-born Black and Latina women from seeking mental health care?
Diagnostic and Treatment Rates for
Depression in Hispanics
• Data from the National Ambulatory Medical Care Survey for the time-frames 19921997, and 2003-2004: Partitioned into four, 2-year time intervals for trend analysis
among patients aged 20-79 years.
• From 1992-1993 to 2003-2004, annualized rate of visits documenting diagnosis of
depression increased from 10.9 to 15.4 per 100 US population for whites, from 4.2
to 7.6 for blacks, and from 4.8 to 7.0 for Hispanics.
• A concomitant diagnosis of depression and antidepressant use increased from 6.5
to 11.4 per 100 for whites, from 2.6 to 5.2 for blacks, and from 3.0 to 5.6 for
• By 2003-2004, diagnostic and treatment rates were
comparable among blacks and Hispanic, but were less than
half the observed rates for whites.

Ethnicity/race and the diagnosis of depression and use of antidepressants by adults in the United States.
Diagnostic and Treatment Rates for
Depression in Hispanics
• Systematic review the literature to determine whether racial disparities exist in the
diagnosis and treatment of depression in the United States.
• PubMed search of population-based studies examining the diagnosis and/or
treatment of depression; or data from prospective studies stratifying the rates of
diagnosis and/or treatment of depression by race/ethnicity and ethnic comparisons
between Caucasians, African Americans and/or Hispanics.
• Initial searches identified 2,396 articles.
• 14 articles: eligible for inclusion.
• Four included data on the diagnosis of depression in different ethnic groups
• Results were not consistent.
• Twelve included data on treatment variability in the treatment of depression.
• Overall lower rates of treatment for African Americans and
Hispanics than for Caucasians.
• More research is needed focusing on ethnic variation in the diagnosis of

Hispanic and Suicide
• Data are from the National Violent Death Reporting System (NVDRS), a
state-based data integration system
• For 2004 data from 13 US states.
• NVDRS integrates medical examiner, toxicology, death certificate, and
law enforcement data.
• Comorbid substance abuse and mental health problems were more
likely among non-Hispanic whites and non-Hispanic blacks, while
Hispanics were more likely to have a substance abuse problem without
comorbid mental health problems.
• Hispanics were less likely to have been diagnosed with a
mental illness or to have received treatment, although
family reports of depression were comparable to nonHispanic whites and other racial/ethnic groups.

Hispanic Perception of Antidepressant
Treatment Modalities
 Depressed Hispanic patients' perceptions of primary care treatments and the
specific benefits associated with them.
 Semi-structured interviews with 121 depressed Hispanic patients .
 More than half of patients viewed physician consultation and medication as helpful.
 Almost all patients considered psychotherapy to be helpful.
 Supportive talk - the most commonly mentioned specific benefit of physician
 The most common benefit of medication: anxiolytic, sedative effect.
 Energizing effects: less common.
 Most common benefits associated with psychotherapy: support, advice, and
 Patients currently taking medication for depression had a more favorable view of
pharmacological treatment.
 Differences by language of interview were noted.
 English speakers - twice as likely as Spanish speakers to believe that medication
would have tonic effects, making them more active, energetic, or able to
concentrate (21% vs 10%).

STAR*D Outcomes for Hispanics
 Sequenced Treatment Alternatives to Relieve Depression (STAR*D) compared rates
of remission and response for blacks (n = 495), whites (n = 1853), and Hispanics (n =
327) with non-psychotic major depressive disorder treated with citalopram.
 Outpatients treated in 23 psychiatric and 18 primary care centers.
 Participants received flexible doses of citalopram for up to 14 weeks, with dosage
adjustments based on clinical assessments.
 Goal: remission.
 Significant differences among groups on many baseline demographic, sociocultural,
and clinical variables.
 Blacks and Hispanics - more socially disadvantaged and more co-morbidity than
 Before adjusting for differences, blacks had lower remission rates than whites, with
Hispanics intermediate between the 2.
 After adjustments, remission rates for groups were not significantly
different on the 17-item HRSD, but lower for blacks compared with whites with
the 16-item QIDS-SR.

Antidepressant Discontinuation
in Latinos
• Despite growth in number of antidepressant medications, many patients discontinue
• Reasons such as nonresponse, side effects, stigma, and miscommunication.
• Some analysts have suggested that Latinos may have higher antidepressant
discontinuation rates than other US residents.
• This paper examines Latino antidepressant discontinuation, using data from a
national probability survey of Latinos in the USA.
• In this sample, 8% of Latinos had taken an antidepressant in the preceding 12
• Among those users, 33.3% had discontinued taking antidepressants at the time of
interview, and half had done so without prior input from their physician.
• Even controlling for clinical and other variables, patients who reported good or
excellent English proficiency were less likely to stop at all.
• Patients were also less likely to stop if they were older, married, had public or
private insurance, or had made eight or more visits to a nonmedical therapist.

Cuban-Americans - UM Focus
“Cuban” is primary identification - even for US born.
“Different” immigrant group.
Limited to no identification with newly arrived.
Common cultural values: Family - honor - word
View of medical research: “guinea pig” - suspicion.
Older individual: complete mistrust / suspicion of medical
Take meds as they think right.
Share meds among friends/family.
Self medication with Rx meds - highly common.
Cultural shift - YUCAs - much more accepting of American
medicine and medical establishment.
Mistrust of drug companies whose mission is selling drugs.
Therefore, addressing symptoms, not searching for cures.
Hope: “cure” - Fear: unexpected side effects: “Celebrex.”
Pharmacogenomics of
Antidepressant Treatment in
Mexican Americans
“The complexity of this field is best
approached by rigorous explorations of
known candidate systems in conjunction
with the use of genomic tools to discover
new targets for antidepressants and to
predict clinical outcomes.”

• Depression is an important health problem in Hispanics (as much as
in the overall population).
• Hispanics are the largest minority group in the US.
• Cultural factors impact on the treatment of depression in Hispanics.
• Rates of dx and tx are lower in Hispanics than in whites (<50%).
• STAR*D - After adjustments, remission rates for groups were not
significantly different on the 17-item HRSD.
• English speakers more likely to see benefits of pharmacological
antidepressant treatment.
• Genetic factors also underlie the predisposition to depression and
antidepressant treatment response in Mexican-Americans.
• Findings from Mexican-Americans replicated in others (Chinese,
African-Americans); from replication to scientific discovery.
