Factors Associated with the Incidence of Prediabetes in Bogor, Indonesia: A Cohort Study.

Background: Prediabetes is a golden period because the blood sugar levels can be lowered to normal levels, unlike diabetes mellitus. Studies on risk factors of prediabetes in Indonesia have never been conducted before, especially with cohort study design. The purpose of this study was to identify risk factors associated with prediabetes in Indonesia based on a cohort study conducted in Bogor, Indonesia. Study Design: A retrospective cohort study.

Methods: This study was conducted using data from the Bogor Cohort Study done by the Ministry of Health of Indonesia, which included individuals aged more than 25 years. Individuals who had impaired fasting glucose (IFG) (100-125 mg/dL) and/or impaired glucose tolerance (IGT) (140-199 mg/dL) at baseline screening were excluded from the study. Demographic characteristics, risk factors, and clinical observations were extracted using a questionnaire. Cox regression was used for data analysis.

Results: The cumulative incidence of prediabetes in Bogor was 50.3%. Factors associated with prediabetes were old age (RR: 1.33; 95% CI 1.19, 1.47), female gender (RR: 1.32; 95% CI 1.18, 1.48), overweight (RR: 1.17; 95% CI 1.01, 1.36), obesity (RR: 1.26; 95% CI 1.08, 1.46), central obesity (RR: 1.17; 95% CI 1.02, 1.34), high cholesterol levels (RR: 1.11; 95% CI 1.00, 1.22), and hypertension (RR: 1.27; 95% CI 1.14, 1.42).

Conclusion: Age is a dominant risk factor for prediabetes. Therefore, it is important to stick to a healthy lifestyle by doing more physical activities and maintaining a balanced diet since young age to prevent prediabetes.
