Abstract

Background: The health of the agricultural population has been previously explored, particularly in relation to the

farming exposures and among professionally active individuals. However, few studies specifically focused on health

and aging among elders retired from agriculture. Yet, this population faces the long-term effects of occupational

exposures and multiple difficulties related to living and aging in rural area (limited access to shops, services, and

practitioners). However, these difficulties may be counter-balanced by advantages related to healthier lifestyle, richer

social support and better living environment. The general aim of the AMI cohort was to study health and aging in

elderly farmers living in rural area through a multidisciplinary approach, with a main focus on dementia.

Methods/design: The study initially included 1 002 participants, randomly selected from the Farmer Health

Insurance rolls. Selection criteria were: being 65 years and older; living in rural area in Gironde (South-Western

France); being retired from agriculture after at least 20 years of activity and being affiliated to the Health Insurance

under own name. The study started in 2007, with two follow-up visits over 5 years. Baseline visits were conducted

at home by a neuropsychologist then by a geriatrician for all cases suspected of dementia, Parkinson’s disease and

depression (to confirm the diagnosis), and by a nurse for others. A large panel of data were collected through

standardised questionnaires: complete neuropsychological assessment, material and social living environment,

psychological transition to retirement, lifestyle (smoking, alcohol and diet), medications, disability in daily living,

sensory impairments and some clinical measures (blood pressure, depression symptomatology, anxiety, visual test,

anthropometry...). A blood sampling was performed with biological measurements and constitution of a biological

bank, including DNA. Brain MRI were also performed on 316 of the participants. Finally, the three-year data on

health-related reimbursements were extracted from the Health System database (medications, medical and

paramedical consultations, biological examinations and medical devices), and the registered Long-Term Diseases

(30 chronic diseases 100% covered by the Insurance System).

Discussion: AMI is the first French longitudinal study on health and aging set up in a population of elderly farmers

living in rural area through a multidisciplinary approach.
