MICASA: Mexican Immigration to California: Agricultural Safety and Acculturation

Aim: Characterize occupational and general health in immigrant Hispanic population


Micasa reproductive health1

MICASA Study Site

Mendota: Central Valley agricultural community

Population 9,791 in 2005; 97% Hispanic

One-third below federal poverty level


Micasa reproductive health2
MICASA: Reproductive Health


12.9% of US population are foreign-born

1,062,040 legal permanent residencies (LPRs) (2011)

Greatest source (13.4%) is Mexico

11.5 million undocumented immigrants

59% born in Mexico

Micasa reproductive health3

Where do immigrants go?

Employment: Agriculture

Low entrance barriers

Location: Rural

California is destination for ~20% of LPRs

Employment, social networks


Micasa reproductive health4

Agricultural Environment

Highly productive and diverse

California produces over 350 crops with a market value of $26.6 billion in cash receipts in 2011

(Iowa is in second place, with $21 billion in 2011)

California leads the nation in major production categories: field crops, vegetables and melons, livestock and dairy, nursery products.

Hispanic Paradox

Hispanics have better health outcomes (for some conditions) than do Non-Hispanic Whites, despite SES disadvantage

Coronary heart disease mortality

Reproductive health outcomes

Not seen for diabetes, obesity

Micasa reproductive health6
MICASA: Reproductive Health

Hispanic Paradox

AKA “Latina epidemiologic paradox” when applied to reproductive health outcomes

Low birth weight

Small for gestational age (SGA)

Pre-term birth

Micasa reproductive health7

Latina Epidemiologic Paradox

Not seen in all Hispanic groups

Protective effect is strongest in Mexico-born with low educational attainment.

Micasa reproductive health8

Lifestyle factors affecting reproductive health:

Age of sexual debut

Lifetime number of sexual partners

Use of protective measures

Acculturation affects these factors

Micasa reproductive health9
MICASA: Reproductive Health

Acculturation affects lifestyle

Increased acculturation associated with . . .

Earlier sexual debut (mean 19.0 vs. 15.9 y) in pregnant women at SJ County health clinic

Increased likelihood of multiple lifetime sexual partners

[Kasirye, et al. . Ethn Dis. 2005;15(4):733-739]

Descriptive: Examine selected reproductive health outcomes in relation to area of birth and other demographic characteristics.

Analytic: Test hypotheses that acculturation, depression, perceived stress, and family support affect reproductive outcomes.

Micasa reproductive health11
MICASA: Reproductive Health


Multistage sampling of FW households (> 1 adult working > 45 days in agriculture in prior year

467 (65%) of eligible households

Baseline interview 1/2006 – 4/2007

Follow-up interview (74%) 11/2008 – 2/2010

(Limit to persons born in Mexico or Cent. Am)

Micasa reproductive health12
MICASA: Reproductive Health

Results (Demographics):

399 women

407 men Total: 806

556 born in Mexico

250 born in CA (90% from El Salvador)

Micasa reproductive health13
MICASA: Reproductive Health

Results (Demographics):

Median ages ranged from 39 y (Mexican men) to 34 y (CA men and women)

Median ages at immigration ranged from 20 y (Mexican men) to 24 y (CA women)

> 90% low acculturation

Median time in current domicile 3 y

Micasa reproductive health14
MICASA: Reproductive Health

Results (Demographics):

95% married or cohabiting

Marriage prevalence ranged from 47% (CA women) to 76% (Mexican men)

Micasa reproductive health15
MICASA: Reproductive Health

Results (Sexual debut and partners):

Median age at sexual debut ranged from 16 y (CA men) to 18 y (women)

Median number of lifetime sexual partners was 1 for women, 2 (for Mexican men) and 3 (for CA men)

Sexually transmitted diseases rare (<3.7%)

> 75% of women had Pap within 1 year

Micasa reproductive health16
MICASA: Reproductive Health

Results (Contraception):

Men: 45.2% (Mexican); 46.7% (CA)

Women: 68.7% (Mexican); 53.9% (CA)

Men less likely to use contraception; more likely to use poorly effective methods (condom)

Micasa reproductive health17
MICASA: Reproductive Health

Results (Contraception):

75% of women “mostly” or “very” confident about ability to use contraception in next 6 mo.

Major reason for non-use “don’t want to” or current or desired pregnancy

1 woman and 13 men cited partner’s wish as reason for non-use

Micasa reproductive health18
MICASA: Reproductive Health

Results (Contraception):

Among persons at risk for unintended pregnancy at study entrance . . .

Men had 2x (CA) to 4x (Mex) increased odds for non-use of contraception compared towomen

CA women had 2x increased odds for non-use of contraception compared to Mexican women.

Micasa reproductive health19
MICASA: Reproductive Health

Results (Pregnancy):

Median 3 pregnancies reported on baseline survey—no relation with region of birth

84 interim pregnancies (i.e., following baseline and reported on follow-up survey)

Desire for interim pregnancy modestly higher among CA women (NS)

Micasa reproductive health20
MICASA: Reproductive Health

Summary and conclusions:

MICASA population (vs. US) . . .

Later sexual debut than US-born

Contraception use comparable to US

Greater total fertility (3 for CA, 4 for Mexico)

1.9 for US women, 2.2 for US Hisp

Micasa reproductive health21
MICASA: Reproductive Health

Summary and conclusions:

Men (vs women) . . .

Moderately older and more years in US

Earlier sexual debut; more partners

Lower use of contraception; less effective methods

More likely married

Micasa reproductive health22
MICASA: Reproductive Health

Summary and conclusions:

Central America (vs Mexico) . . .

Fewer years in US

Earlier sexual debut (esp. among men)

Lower use of contraception amongwomen

Lower odds of being married

Micasa reproductive health23
MICASA: Reproductive Health

Summary and conclusions:


Community-based study of important population

Few data

Strong community engagement

Micasa reproductive health24
MICASA: Reproductive Health

Summary and conclusions:


Single California community—may not apply to dissimilar groups and locations

Limited depth of inquiry (space limits)

Questionnaire responses—no validation

Micasa reproductive health25
MICASA: Reproductive Health

Public health implications:

Lifestyle factors brought from sending country may persist, especially in cultural enclaves

Homogeneity of groups may facilitate development of effective interventions

Attention to men, who have higher-risk profile than women
