Potential Opportunity

Electronic medical records (EMRs) offer a potential opportunity to identify patients at high risk for cardiometabolic disease, which encompasses type 2 diabetes and cardiovascular disease (CVD). The objective of this retrospective cohort study is to use information gathered from EMR to investigate the association between triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) and cardiometabolic outcomes in a general population of subjects over 50 years of age during a follow-up period of 8–9 years. TG/HDL-C was recorded for each of 1428 subjects in 2008, and diagnoses of type 2 diabetes and CVD were recorded through chart review until 2017. Cox proportional hazards models controlling for demographic characteristics and other risk factors demonstrated that high TG/HDL-C (>2.5 in women or >3.5 in men) was significantly associated with increased incidence of type 2 diabetes (HR 1.66; 95% CI 1.07 to 2.57; p=0.0230). There was also a suggested association between high TG/HDL-C and incidence of CVD (HR 1.51; 95% CI 0.98 to 2.35; p=0.0628). These findings suggest that using TG/HDL-C, which can be easily calculated from data in an EMR, should be another tool used in identifying patients at high cardiometabolic risk.

AbstractThe aim of this study was to investigate the associations for specified substitutions between different subgroups of dairy products and the risk of type 2 diabetes. We used data from the Danish Diet, Cancer and Health cohort including 54 277 men and women aged 50–64 years at baseline. Information regarding intake of dairy products was obtained from a validated FFQ, and cases of type 2 diabetes were identified through the Danish National Diabetes Register. Cox proportional hazards regressions were used to estimate associations. During a median follow-up of 15·3 years, 7137 cases were identified. Low-fat yogurt products in place of whole-fat yogurt products were associated with a higher rate of type 2 diabetes (hazard ratio (HR) 1·17; 95 % CI 1·06, 1·29) per serving/d substituted. Whole-fat yogurt products in place of low-fat milk, whole-fat milk or buttermilk were associated with a lower rate of type 2 diabetes (HR 0·89; 95 % CI 0·83, 0·96; HR 0·89; 95 % CI 0·82, 0·96; HR 0·89; 95 % CI 0·81, 0·97; per serving/d substituted, respectively). The pattern of associations was similar when intake was expressed as kJ/d (kcal/d). These findings suggest that intake of whole-fat yogurt products in place of low-fat yogurt products, low-fat milk, whole-fat milk and buttermilk are associated with a lower rate of type 2 diabetes.

OBJECTIVE_ To explore the incidence cases of diabetes over 35 years of follow-up in middle-aged Swedish men in relation to their severity of stress at baseline. RESEARCH DESIGHN AND METHODS_ This was a population-based random sample of 7 495 men derived from the Primary Prevention cohort study (Gothenburg) aged 47-55 years and without prior history of diabetes at baseline (1970-1973). Self-perceived psychological stress during the previous years was assessed with a single-item in the questionnaire. Incident diabetes from hospital discharge and death registries was collected during the 35 years follow-up. Cox proportional hazards regression was used to evaluate association of stress with incidence of diabetes. RESULTS_ During the follow up of 35 years, 884 men developed diabetes. The crude incidence rate was 46.32 per 1000 persons-years. At baseline, 15.5% men reported to experience permanent stress. The age-adjusted cumulative incidence of type diabetes in men who had permanent stress was 16%, compared with 12% for those with no or periodic stress. In age-adjusted Cox regression analysis, men with permanent stress had a higher risk of diabetes incident (hazard ratio 1.52 [95% CI 1.26-1.82]) compared with men with periodic or no stress (referent). The excess risk of diabetes incident associated with permanent stress remained significant after adjusting for age, socioeconomic status (SES), smoking, physical inactivity, alcohol abuse, height, BMI, serum-cholesterol, hypertension, systolic and diastolic blood pressure. CONCLUSIONS_ Perceived permanent stress in middle aged Swedish men was an important long-term predictor of diabetes incidence. The association of stress was independent of SES, lifestyle and other conventional type 2 diabetes risk factors. The significant impact of stress on diabetes, as demonstrated in this study, emphasizes need for prevention strategies including intervention programmes for people with permanent stress.

Abstract Context There is evidence that diabetes-related complications are declining but most data sources have limitations. Objective To characterize temporal changes in incidence rates (IRs) of chronic complications and mortality in well-characterized, community-based Australians. Design Longitudinal observational study. Setting Urban population. Participants Participants with type 2 diabetes from the Fremantle Diabetes Study phases I (FDS1; n = 1291 recruited 1993-1996) and II (FDS2; n = 1509 recruited 2008-2011) age-, sex,- and ZIP code-matched 1:4 to people without diabetes. Main outcome measures First hospitalizations for/with myocardial infarction (MI), stroke, heart failure (HF), lower extremity amputation, and cardiovascular disease (CVD) and all-cause mortality. Five-year IRs, IR ratios for those with versus without diabetes in FDS1 and FDS2, and IR differences (IRDs), were calculated. Results The 13,995 participants had a mean age of 64.8 years and 50.4% were males. There were lower IR ratios for MI, stroke, HF, and CVD death in FDS2 versus FDS1. IRDs for people with versus without type 2 diabetes had reduced by &gt;50% between phases for MI, stroke, HF, lower extremity amputation, and CVD death, with no change in IRD for all-cause mortality. Within the pooled type 2 diabetes cohort, FDS2 versus FDS1 participation was an independent inverse predictor of stroke, HF, CVD death, and all-cause mortality after adjustment in Cox proportional hazards models. Conclusions Cardiovascular outcomes in Australians have improved since the 1990s, especially in type 2 diabetes. The difference in all-cause mortality between those with and without type 2 diabetes has persisted despite longer survival.

Background Results from studies on diabetes and migraine risk are conflicting, which may be due to methodological limitations. Prospective studies with long follow-up could increase our understanding of the relationship between the two diseases. Method We performed a cohort study including the whole Norwegian population alive on 01.01.2004, using prescriptions registered in the Norwegian prescription database to identify individuals developing type 1 diabetes, type 2 diabetes and migraine during follow-up (10 years). We used Cox proportional hazards regression to estimate rate ratios with corresponding 95% confidence intervals for the effect of diabetes on migraine risk, adjusting for age, sex, and educational level. Result We identified 7,883 type 1 diabetes patients and 93,600 type 2 patients during the study period. Type 1 diabetes was significantly associated with a subsequent decreased migraine risk during follow-up in the age- and sex-adjusted analyses (0.74; 0.61–0.89). Type 2 diabetes was also associated with a significantly lower migraine risk (0.89; 0.83–0.95). Further adjustment for educational level yielded similar results for both diabetes. Conclusion Both type 1 and type 2 diabetes were significantly associated with a decreased risk of migraine. This suggests that diabetes or diabetes treatment may have a protective effect on the development of migraine.

Abstract Objectives Plant-based diets may lower type 2 diabetes (T2D) risk. Whether changes in adherence to plant-based diets are associated with subsequent T2D risk remains unknown. We aimed to evaluate the associations between 4 year changes in plant based diets and subsequent 4 year risk of T2D. Methods We prospectively followed 76,530 women in the Nurses’ Health Study (NHS, 1986–2012), 81,586 women in NHS II (1991–2017), and 34,468 men in the Health Professionals’ Follow-up Study (1986–2016). Diet was assessed every 4 years using validated food-frequency questionnaires. Adherence to plant-based diets was assessed using previously developed indices – the overall plant-based diet index (PDI), the healthful PDI (hPDI), and the unhealthful PDI (uPDI). Self reported T2D cases were validated by supplementary questionnaires. We used multivariable time dependent Cox proportional hazards models to estimate hazard ratios (HR) and 95% CIs for T2D associated with 4 year changes in adherence to plant based diets. Results of the three cohorts were pooled using an inverse variance-weighted meta-analysis. Results We documented 12,016 cases of T2D during 2818,485 person-years of follow-up. After adjustment for initial BMI, initial and 4-year changes in lifestyle and other factors, compared with participants whose indices remained relatively stable (±3%), participants with the largest 4-year decrease (&gt;10%) in PDI and hPDI had a 12%-23% higher T2D risk in the subsequent 4 years (HR for PDI, 1.12 (95% CI 1.05, 1.20), HR for hPDI, 1.23 (1.16, 1.31)). Conversely, each 10% incremental increase in PDI and hPDI over 4 years was associated with a 7%–9% lower T2D risk in subsequent 4 years (HR for PDI, 0.93 (0.90, 0.95), HR for hPDI, 0.91 (0.87, 0.95)). Changes in uPDI were not associated with T2D risk. Further adjustment for concurrent changes in body weight, a potential mediator, modestly attenuated the associations but results remained significant. We estimated that body weight changes explained 6.0%–36% of the associations between 4 year changes in PDI and hPDI and subsequent T2D risk. Conclusions Improving adherence to overall and healthful plant based diets over a 4 year period was associated with a lower T2D risk, whereas decreased adherence to overall and healthful plant based diets was associated with a higher T2D risk.

Reproductive Ageing

Abstract Aims/hypothesis Given its role in ovarian follicle development, circulating anti-Müllerian hormone (AMH) is considered to be a marker of reproductive ageing. Although accelerated reproductive ageing has been associated with a higher risk of type 2 diabetes, research on the relationship between AMH and type 2 diabetes risk is scarce. Therefore, we aimed to investigate whether age-specific AMH levels and age-related AMH trajectories are associated with type 2 diabetes risk in women. Methods We measured AMH in repeated plasma samples from 3293 female participants (12,460 samples in total), aged 20–59 years at recruitment, from the Doetinchem Cohort Study, a longitudinal study with follow-up visits every 5 years. We calculated age-specific AMH tertiles at baseline to account for the strong AMH–age correlation. Cox proportional hazards models adjusted for confounders were used to assess the association between baseline age-specific AMH tertiles and incident type 2 diabetes. We applied linear mixed models to compare age-related AMH trajectories for women who developed type 2 diabetes with trajectories for women who did not develop diabetes. Results During a median follow-up of 20 years, 163 women developed type 2 diabetes. Lower baseline age-specific AMH levels were associated with a higher type 2 diabetes risk (HRT2vsT3 1.24 [95% CI 0.81, 1.92]; HRT1vsT3 1.62 [95% CI 1.06, 2.48]; ptrend = 0.02). These findings seem to be supported by predicted AMH trajectories, which suggested that plasma AMH levels were lower at younger ages in women who developed type 2 diabetes compared with women who did not. The trajectories also suggested that AMH levels declined at a slower rate in women who developed type 2 diabetes, although differences in trajectories were not statistically significant. Conclusions/interpretation We observed that lower age-specific AMH levels were associated with a higher risk of type 2 diabetes in women. Longitudinal analyses did not show clear evidence of differing AMH trajectories between women who developed type 2 diabetes compared with women who did not, possibly because these analyses were underpowered. Further research is needed to investigate whether AMH is part of the biological mechanism explaining the association between reproductive ageing and type 2 diabetes.

Weight Fluctuation

We aimed to investigate how body weight fluctuation affects the risk of developing type 2 diabetes by conducting a nationwide cohort study. A total of 3,855,884 participants from the National Health Insurance System health check-up data from 2012 were included in this study, and follow-up continued until 2016. Body weight was measured at least thrice between 2009 and 2012. Body weight variability (BWV) was estimated using average successive variability (ASV) indices. Cox proportional hazards regression models were used to evaluate the association of BWV with the risk of type 2 diabetes using hazard ratios (HRs) and 95% confidence intervals (CIs). Body weight fluctuation was associated with a higher risk of incident diabetes after adjustment for confounders (HR 1.10, 95% CI 1.07, 1.12 in the highest BWV quartile compared to the lowest). Regardless of the weight change status, the highest ASV quartile of BWV increased the risk for diabetes. Even subjects with a normal glucose tolerance status and those aged under 65 years had a higher risk of diabetes if their body weight highly fluctuated during the follow-up years. Our results suggest that body weight variability is an independent risk factor for diabetes. It is important to pay attention to frequent body weight fluctuations.
