چکیده
OBJECTIVE The aim of this study was to investigate the association between family history of diabetes (FHD) and prevalence and incidence of LADA, type 1 and type 2 diabetes. RESEARCH DESIGN AND METHODS The results were based on cross-sectional data from 64,498 men and women ≥20 years in the Nord-TrØndelag Health Study, including 128 cases of LADA; 1,134 cases of type 2 and 123 cases of type 1 diabetes. In addition, prospective data on 46,210 subjects, including 80 incident cases of LADA, observed between 1984-86 and 1995-97 were available. Patients with LADA had antibodies against GAD and were insulin independent at diagnosis. RESULTS FHD was associated with a 4 times (Odds Ratio (OR) =3.92, 95% CI=2.76-5.58) increased prevalence of LADA. Corresponding estimates for type 2 diabetes and type 1 diabetes were 4.2 (95% CI=3.72-4.75) and 2.78 (95% CI=1.89-4.10), respectively. LADA patients with FHD had lower levels of C-peptide (541 vs. 715 pmol/l) and were more often insulin treated (47 % vs. 31%), than patients without FHD. Prospective data indicated that subjects with siblings with diabetes had a 2.5 (95% CI=1.39-4.51) times increased risk of developing LADA during the 11-year of follow-up compared to those without. CONCLUSIONS This study indicates that FHD is a strong risk factor for LADA and that the influence of family history may be mediated through a heritable reduction of insulin secretion.
