The Influence of Family History Risk Levels of Diabetes on Disease Prevalence in a High-Risk Diabetic Chinese Population

Abstract Background: Diabetes is associated with genetic susceptibility, and family history is a risk factor. The study investigated the association between different family history risk levels and the prevalence of diabetes in a multi high-risk cohort and evaluated the impact of family history of diabetes on insulin secretion and insulin sensitivity. Materials and Methods: We analyzed data from 9754 adults who participated in the Shanghai High-Risk Diabetic Screen Project between 2002 and 2012. The association among three family history risk levels (mild, moderate, and high) with the prevalence of diabetes, insulin secretion, and insulin sensitivity was evaluated in the multi high-risk cohort. Results: Overall, 69.6%, 24.8%, and 5.6% of participants were categorized as having mild, moderate, and high familial risk, respectively. The standardized prevalence was higher in the high family history risk group (43.1%) than in the moderate group (37.3%) and in the mild group (23.5%) (P < 0.001). The odds ratios...
