Migration Status and Prevalence of Chronic Diseases in Kerala State, India

Abstract EN

Aim.

To study the relationship between a personal history of migration and prevalence of chronic diseases and risk factors in a rural population.

Method.

Cross sectional survey data from PROLIFE, a cohort study involving the long time follow-up of the residents of an administrative unit in Kerala, India, was used.

Pre-tested questionnaire was administered to 78,173 adult residents.

Information on physician diagnosed diabetes, hypertension, and cardiac diseases and lifestyle attributes like physical activity, habits, and migration was captured.

Results.

Subjects with a history of migration had a higher prevalence of chronic disease when compared with those with no history of migration.

Diabetes (19.6% versus 4.1%), hypertension (18.8% versus 6.6%), and cardiac complaints (8.6% versus 4.1%) are more prevalent among those with history of migration of over 5 years.

After adjustment for age, gender, and education, we found that chronic diseases are higher among persons with a history of migration (OR 2.2, 95% CI: 2.1–2.3).

Age-specific increases in prevalence of chronic diseases are also substantially higher among migrants.

Conclusion.

People with a history of migration have a higher prevalence of chronic diseases and risk factors.
