Abstract

OBJECTIVES
The aim of this study was to clarify the clinical trait of familial diabetes mellitus (DM) by analyzing participants’ risk of DM according to the age of DM onset in parents and siblings, and to evaluate individuals’ risk of DM-associated cardiometabolic diseases.

METHODS

Altogether, 211,173 participants aged ≥40 years from the Korean Genome and Epidemiology Study were included in this study. The participants were divided into groups based on the number (1 or 2 relatives) and age of onset (no DM and early, common, or late onset) of familial DM. Participants’ risk of DM was assessed using a Cox regression model with hazard ratios and 95% confidence intervals (CIs). A logistic regression model with odds ratios was used to evaluate associations among the participants’ likelihood of acquiring cardiometabolic diseases such as hypertension, chronic kidney disease (CKD), and cardiovascular disease.

RESULTS

The risk of developing DM was 2.02-fold (95% CI, 1.88 to 2.18) and 2.88-fold (95% CI, 2.50 to 3.33) higher, respectively, in participants with 1 and 2 family members diagnosed with familial DM. It was 2.72-fold (95% CI, 2.03 to 3.66) higher in those with early-onset familial DM. In the early-onset group, the respective risks of hypertension and CKD were 1.87-fold (95% CI, 1.37 to 2.55) and 4.31-fold (95% CI, 2.55 to 7.27) higher than in the control group.

CONCLUSIONS

The risk of DM and related cardiometabolic diseases was positively associated with the number of family members diagnosed with DM and an early diagnosis in family members with DM.

Summary

Korean summary
본 연구는 한국인유전체역학조사사업 역학자료를 이용하여, 당뇨병을 진단받은 가족 구성원 (부모 및 형제)의 수가 많고 당뇨병이 조기에 발생할수록 개인의 당뇨발생 위험도가 높아짐을 보고하였습니다. 또한 당뇨병이 조기에 발생한 가족구성원이 있을 경우 개인의 일부 심대사질환과의 연관성이 있을 수 있음을 설명하였습니다.

Key Message
This study demonstrated that the risk of diabetes in individuals was significantly associated with the quantity and the onset of family members diagnosed with diabetes. We also explained that having a family member with early-onset diabetes can be associated with some cardiometabolic diseases in individuals.

Abstract

<sec><title>OBJECTIVES</title>The aim of this study was to evaluate whether clinical test values from different laboratories in the Korean Genome and Epidemiology Study (KoGES) can be integrated through a statistical adjustment algorithm with appropriate intra- and inter-laboratory reliability.</sec><sec><title>METHODS</title>External quality control data were obtained from the Korean Society for Laboratory Medicine and quadruplicated standardized serological samples (N=3,200) were manufactured in order to check the intra- and inter-laboratory reliability for aspartic acid transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transpeptidase (γ-GTP), blood urea nitrogen (BUN), creatinine, uric acid (UA), fasting blood sugar (FBS), cholesterol, and triglyceride (TG). As an index of inter- and intra-rater reliability, Pearson's correlation coefficient, intraclass correlation coefficients and kappa statistics were estimated. In addition, to detect the potential for data integration, we constructed statistical compensation models using linear regression analysis with residual analysis, and presented the R-square values.</sec><sec><title>RESULTS</title>All correlation coefficient values indicated good intra- and inter-laboratory reliability, which ranged from 0.842 to 1.000. Kappa coefficients were greater than 0.75 (0.75-1.00). All of the regression models based on the trial results had strong R-square values and zero sums of residuals. These results were consistent in the regression models using external quality control data.</sec><sec><title>CONCLUSION</title>The two laboratories in the KoGES have good intra- and inter-laboratory reliability for ten chemical test values, and data can be integrated through algorithmic statistical adjustment using regression equations.</sec>
