Occupational Health Problems Among Agricultural Workers
“A textbook of occupational disease”
• • • • • • • • • • • Injuries; acute and cumulative Respiratory disease Dermatologic disease Infectious disease Heat stress Cancer Adverse reproductive outcomes Mental illness Pesticide illness (acute, chronic) Neurologic disease Etc.

Tuberculosis among Agricultural Workers
• (+) PPD was twice as common among Mexican-born than US-born California farmworkers, independent of age and smoking (McCurdy, 1997).
• A North Carolina study found (+) PPD in 33% of Hispanic farmworkers, and active TB in 0.47% (Ciesielski, 1991). • Migrant day labor farmworkers (solo males) may have (+) PPD prevalence of 37 - 48%. • Drug resistant TB is 2-6x more common among immigrant farmworkers born outside the U.S.

Immigration,
Acculturation

and Health

The Hispanic Reproductive Paradox
• Many health behaviors and health outcomes worsen after immigration to the U.S. despite increased income and access to health care.
• Latinas have a higher risk profile, yet fewer preterm, low birthweight births (PTLBW ) in Mexico • Birth outcomes worsen the longer immigrants reside in the US, despite access to better medical care and social services

Two Hypotheses for Paradox
• Immigrant women are a healthy subsection of the population of origin, and therefore, have better than expected birth outcomes, i.e. Healthy Immigrant Hypothesis • Behavioral practices from country of origin protect immigrant women in the U.S. from risks associated with disadvantaged SES once in the U.S. This “protection” decreases with acculturation.

Acculturation
• Change experienced by members of immigrant groups as they adopt the culture (i.e. language, norms, values) of the dominant group in the host society
• During the acculturation process Hispanics, and other immigrants, undergo a variety of behavioral, cultural, and occupational changes that may be related to their health

What is the Underlying Cause for Acculturation-Associated Behavioral Changes?
• • • • • Increased income Increased opportunity (access) Peer group pressure Loss of family influence Stress

• Targeted advertising campaigns

Health Care Implications for Immigrant Farmworkers
• Overall health status of immigrants, especially agricultural workers in U.S. is poorer than comparable non-farmworker, non-immigrant populations
• Factors affecting farmworker health include:

– Low socio-economic status, lack of access to care
– Disease patterns in sending countries – Specific occupational hazards of agricultural work

– Environmental exposures

Health Care Implications for Immigrant Farmworkers - 2
• Several adverse health behaviors increase among Hispanics after immigrating to the U.S., and are associated with acculturation. Some of these changes are greater among women immigrants – Cigarette smoking, Alcohol intake, High risk sexual behaviors, Drug use • Understanding the causes of behavioral changes that are associated with acculturation is critical to reversing the current and future adverse health effects of these changes. • Preventive public health efforts should be targeted to those groups at high risk for adopting adverse health behaviors.

Health Care Implications for Immigrant Farmworkers - 3
• Injury rates are higher for immigrant workers, and require particular attention and targeted enforcement of safety standards.
• Risk profiles may be different for men and women, and require culturally sensitive, targeted efforts. • Public health efforts must be blind to immigration status, and directed to diseases that are increased in immigrants (e.g. tuberculosis) that can result in disease transmission after immigration.
