The JUBILE cohort: Quality of life after more than 40 years with type 1 diabetes

The incidence of type 1 diabetes is increasing, and more people are going to live many years with the disease. Quality of life might become the most challenging long-term complication. The JUBILE study describes the quality of life of people living with type 1 diabetes for more than 40 years.

Patients were recruited from 35 French regional or university hospitals: patients and physicians completed questionnaires, validated by the Delphi method. From 1200 questionnaires circulated, 808 patients and their physicians returned questionnaires.

The duration of type 1 diabetes was 49 ± 6 years (mean±SD), age at diagnosis 15 ± 10 years, HbA1c 7.4 ± 0.9% [58 ± 10 mmol/mol] and 52% were men. Macrovascular disease was present in 32%, 46% had no or only mild non proliferative retinopathy. Insulin pumps were used by 25% and insulin pen/syringe users injected 3.9 ± 2.1 times per day. Blood glucose was self monitored at least five times per day by 67% of patients. Men had 1.8 ± 1.2 children, women 1.4 ± 1.0. More than half (55%) of this population was working, 38% had a university degree. Patients still had a busy life, going out (59%), eating out (82%), playing sports (38%) and travelling (66%). No differences appeared based on age, duration of diabetes, demography or social features.

Living a long and pleasant life is possible with type 1 diabetes. Diabetes does not prevent people from having children, working at highly qualified jobs, travelling abroad: a message of hope that is comforting for patients, their family, relatives and the medical teams.
