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. Pulmonary Tuberculosis 5 . TB Prevalence per 100,000 People 15 Honduras 45 Nicaragua 42 Guatemala 21 El Salvador 21 Costa Rica 17 Panamá 52 Source: MMWR-CDC, DGE-SALUD 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 Kasirye, Eth Dis, 2005 Occupation in Past Year by Place of Birth 80% 60% US-born Mex-born 40% 20% 0% Agriculture Service N = 1100 Hispanic women, California Madera, California U.S. Madera Chavinda Chavinda, Michoacan Mexico Binational Comparisons by Acculturation Status 60 50 40 30 20 10 0 Ever smoked Drink alcohol > 1 sex partner Asthma Chavinda Madera (low) Madera (Med/high) 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.
