Factors associated with self-rated health among migrant workers: results from a population-based cross-sectional study in Almaty, Kazakhstan

To determine factors associated with SRH among migrant workers in Almaty, Kazakhstan. In 2007, 805 vendors were screened. Approximately half were eligible (n =450), defined as at least 18 years old, a worker/owner in a randomly selected stall, having traveled 2 + hours outside of Almaty within the past year, and being an internal/external migrant. 28 non-migrants were excluded, leaving 422 participants. Logistic regression was used to examine the relationship between SRH, mental health, and psychosocial problems. Approximately 46% reported having poor or fair SRH. Clinical depression (OR 0.859, 95% CI 0.342-2.154), alcohol problems (OR 1.169, 95% CI 0.527-2.593), and legal status (OR 0.995, 95% CI 0.806-1.229) were not significantly associated with SRH, nor was exposure to interpersonal violence among women (OR 1.554, 95% CI 0.703-3.435). After adjusting for key variables, only ethnicity and social support were found to be significantly protective against poor or fair SRH. SRH was not a comprehensive health measure for these Central Asian migrant workers. More specific questions are needed to identify mental illness and interpersonal violence.
