Abstract P132: Anti-Müllerian Hormone Levels and Risk of Type 2 Diabetes in Women

Introduction: Given its role in ovarian follicle development, circulating anti-Müllerian hormone (AMH) is correlated with timing of menopause. Accordingly, women with higher AMH levels become menopausal at a higher age. Previous research suggests that a higher age at menopause is associated with a decreased risk of type 2 diabetes (T2D). In contrast, AMH levels are increased in women with polycystic ovary syndrome (PCOS), who have a higher risk of insulin resistance and T2D than women without PCOS. However, it is not clear yet whether AMH actually plays a role in the development of T2D. We aimed to investigate whether plasma AMH levels and age-related AMH trajectories are associated with risk of T2D in women. Hypothesis: Higher age-specific plasma AMH levels are associated with a decreased risk of T2D. Methods: We analyzed longitudinal data from 3104 female participants, aged 20-60 years at recruitment, in the population-based Doetinchem Cohort Study. In total, we analyzed 12460 plasma AMH measurements. We calculated age-specific AMH tertiles, to account for the strong AMH-age correlation. Cox Proportional hazards models adjusted for known risk factors for diabetes were used to assess the relation between age-specific AMH tertiles and T2D. We applied linear mixed models to compare age-related AMH trajectories between T2D cases and non-cases. Results: After a median follow-up of 20 years, 163 incident T2D cases were identified. Higher age-specific AMH levels were associated with a lower risk of T2D (hazard ratio (HR) T2vsT1 = 0.77, 95%CI: 0.53-1.11; HR T3vsT1 =0.62, 95%CI: 0.40-0.94; p for trend = 0.02). These findings were supported by predicted AMH trajectories, which suggested that plasma AMH levels were lower at younger ages and declined at a slower rate in women who were diagnosed with T2D compared to women who were not. However, differences in trajectories between T2D cases and non-cases were not statistically significant. Conclusions: We observed that women with higher age-specific AMH levels were at a lower risk of T2D. In addition, our longitudinal analyses may suggest that AMH is lower in women who develop T2D compared to women who do not. These findings are in line with previous studies that observed that a higher age at menopause was associated with a decreased risk of T2D.

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.

Objective We evaluated the associations between changes in plant-based diets and subsequent risk of type 2 diabetes. Methods We prospectively followed 76,530 women in the Nurses’ Health Study (NHS, 1986-2012), 81,569 women in NHS II (1991-2017), and 34,468 men in the Health Professionals’ Follow-up Study (1986-2016). Adherence to plant-based diets was assessed every 4 years using the overall plant-based diet index (PDI), healthful PDI (hPDI), and unhealthful PDI (uPDI). We used multivariable Cox proportional hazards models to estimate hazard ratios (HRs). Results of the three cohorts were pooled using meta-analysis. Results We documented 12,627 cases of type 2 diabetes during 2,955,350 person-years of follow-up. <a>After adjustment for initial BMI, initial and 4-year changes in alcohol intake, smoking, physical activity, and other factors, </a><a>compared with participants whose indices remained relatively stable (±3%), </a><a>participants with the largest decrease (>10%) in PDI and hPDI over 4 years had a 12%-23% higher diabetes risk in the subsequent 4 years (pooled HR: PDI, 1.12 (95% CI 1.05, 1.20), hPDI, 1.23 (1.16, 1.31)). </a>Each 10% increment in PDI and hPDI over 4 years was associated with a 7%-9% lower risk (PDI, 0.93 (0.91, 0.95), hPDI, 0.91 (0.87, 0.95)). Changes in uPDI were not associated with diabetes risk. Weight changes accounted for 6.0%-35.6% of the associations between changes in PDI and hPDI and diabetes risk. Conclusions Improving adherence to overall and healthful plant-based diets was associated with a lower risk of type 2 diabetes, whereas decreased adherence to such diets was associated with a higher risk.

Plasma Metabolome

Background: Plant-based diets have been associated with a lower risk of type 2 diabetes. However, the underlying mechanisms are not completely understood, and the evidence using objective approaches to assess the adherence of plant-based diets is limited. Methods: In the Nurses’ Health Study (NHS), NHSII, and Health Professionals Follow-Up Study, we characterized the plasma metabolome related to plant-based diets and examined its association with the incidence of type 2 diabetes among 10 699 participants. Plasma metabolomic profiling was conducted by liquid chromatography-tandem mass spectrometry. Adherence to plant-based diets was assessed by three plant-based diet indices derived from the food frequency questionnaire: an overall plant-based diet index (PDI), a healthful PDI (hPDI), and an unhealthful PDI (uPDI). Metabolomic signatures reflecting the adherence to plant-based diets were created using elastic net regression, and their associations with risk of type 2 diabetes were subsequently evaluated using multivariable Cox proportional hazards regression. Results: Among 263 metabolites measured, nearly half were significantly associated with PDI (41.4%, 109 of 263), hPDI (51.7%, 136 of 263), and uPDI (40.3%, 106 of 263) after Bonferroni correction. We developed a metabolomic signature comprising 53 metabolites for PDI, 76 metabolites for hPDI, and 88 metabolites for uPDI, each robustly correlated with the corresponding diet index (r=0.34-0.36 for PDI, 0.43-0.44 for hPDI, and 0.36-0.37 for uPDI). We observed an inverse association of PDI metabolomic signature (HR 0.86, 95% CI 0.79-0.93 per one standard deviation) and hPDI metabolomic signature (0.79, 0.72-0.86) with type 2 diabetes risk after adjustment for body mass index and other potential confounders. These two inverse associations remained significant even further adjusting for the corresponding diet index PDI and hPDI. The metabolomic signature for uPDI was not associated with type 2 diabetes risk (1.00, 0.93-1.09). Conclusion: Plasma metabolome can robustly reflect adherence and metabolic response to plant-based diets. Metabolomic signatures reflecting greater adherence to an overall plant-based diet, especially a healthful plant-based diet, were associated with a lower risk of type 2 diabetes. These findings support and provide mechanistic insights on the important role of healthful plant-based diets in diabetes prevention.

Incidence Of Dementia

IntroductionThis study aimed to examine the association between anemia and the incidence of dementia in patients with new-onset type 2 diabetes.Research design and methodsThis study used the Korean National Health Insurance Service-Health Screening Cohort and included 32 590 participants aged ≥40 years who were diagnosed with new-onset type 2 diabetes between 2004 and 2007 and followed up until 2013. Anemia was defined according to the criteria provided by the WHO, hemoglobin <120 g/L for women and <130 g/L for men, and was measured from after diagnosis date of type 2 diabetes to 2007. Dementia was defined by the Classification of Diseases 10th revision code as primary diagnosis and was measured from after hemoglobin measurement to 2013. We calculated the adjusted HR (AHR) and 95% CI to assess the risk of dementia using multivariable Cox proportional hazards regression models.ResultsWe identified 1682 patients who developed dementia within a 7.5-year follow-up. Among patients with type 2 diabetes, patients with anemia were associated with an increased risk of dementia than those without anemia (AHR, 1.21; 95% CI 1.06 to 1.39). Patients with mild (AHR, 1.18; 95% CI 1.03 to 1.38) and moderate (AHR, 1.39; 95% CI 1.06 to 1.83) anemia were associated with an increased risk of dementia than those without anemia among patients with type 2 diabetes. Men (AHR, 1.47; 95% CI 1.16 to 1.83) and middle-aged adults (AHR, 1.31; 95% CI 1.03 to 1.75) with anemia were associated with an increased risk of dementia than their counterparts without anemia among patients with type 2 diabetes.ConclusionsOur findings suggest that anemia is significantly associated with an increased risk of dementia among patients with newly diagnosed type 2 diabetes.

First Time

ObjectivePrevalent type 2 diabetes (T2D) is associated with an increased risk of colorectal cancer and could impair the quality of bowel preparation for colonoscopy. This may in turn increase the risk of overlooked precancerous polyps and subsequent risk of post-colonoscopy colorectal cancer (PCCRC). We investigated whether patients with T2D are at increased risk of PCCRC compared with patients without T2D.DesignWe conducted a population-based cohort study of patients with T2D and without T2D undergoing colonoscopy in Denmark (1995–2015). We investigated the risk of PCCRC by calculating >6 to 36 months cumulative incidence proportions (CIPs) treating death and colectomy as competing risks. Using Cox proportional-hazards regression analyses, we also computed HRs of PCCRC, comparing patients with T2D and non-T2D. According to the World Endoscopy Organization guidelines, we calculated PCCRC 3-year rates to estimate the proportions of T2D and non-T2D CRC patients experiencing PCCRC.ResultsWe identified 29 031 patients with T2D and 333 232 patients without T2D undergoing colonoscopy. We observed 250 PCCRCs among patients with T2D and 1658 PCCRCs among patients without T2D. The >6 to 36 months CIP after a first-time colonoscopy was 0.64% (95% CI 0.55% to 0.74%) for T2D and 0.36% (95% CI 0.34% to 0.38%) for patients without T2D. The HRs of PCCRC were 1.43 (95% CI 1.21 to 1.72) after a first-time colonoscopy and 1.18 (95% CI 0.75 to 1.85) after a second-time colonoscopy. The PCCRC 3-year rate was 7.9% for patients with T2D and 7.4% for patients without T2D.ConclusionT2D may be associated with an increased HR of PCCRC.

Design And Methods

Objective: In 2019 the EAT-Lancet Commission proposed a dietary pattern, defined to be globally environmentally sustainable, but untested directly in population studies with regards to health. We investigated adherence to the EAT-Lancet diet and risk of incident type 2 diabetes in a Danish setting. Research design and methods: In total, 54,232 participants aged 50-64 years at inclusion (1993-1997) with no previous cancer or diabetes diagnoses were included. Dietary data were collected using a validated 192-item food frequency questionnaire, and scored 0 (non-adherence) or 1 (adherence) point for each of the 14 dietary components of the EAT-Lancet diet (range 0-14 points). Incident type 2 diabetes cases were identified using the Danish National Diabetes Register. Hazard ratios and 95% confidence intervals (CI) were estimated using multivariable-adjusted Cox proportional hazards models. Results: During follow-up (median 15 years), 7130 participants developed type 2 diabetes. There was a 22% (95% CI: 14%; 29%) lower risk of type 2 diabetes among those with the greatest adherence to the EAT-Lancet diet (11-14 points) compared to those with the lowest adherence (0-7 points). After further adjusting for potential mediators, the corresponding risk was 17% (95% CI: 8%; 24%) lower. Conclusion: Adherence to the EAT-Lancet diet was associated with a lower risk of developing type 2 diabetes in a middle-aged Danish population.

OBJECTIVE: To conduct post-hoc secondary analysis examining the association between change in physical activity (PA), measured with self-report and accelerometry, from baseline to 1 and 4 years and cardiovascular disease (CVD) outcomes in the Look AHEAD Trial. RESEARCH DESIGN AND METHODS: Participants were adults with overweight/obesity and type 2 diabetes with PA data at baseline and year 1 or 4 (n = 1,978). Participants were randomized to diabetes support and education or intensive lifestyle intervention. Measures included accelerometry-measured moderate-to-vigorous PA (MVPA), self-reported PA, and composite (morbidity and mortality) CVD outcomes. RESULTS: In pooled analyses of all participants, using Cox proportional hazards models, each 100 MET-min/wk increase in accelerometry-measured MVPA from baseline to 4 years was associated with decreased risk of the subsequent primary composite outcome of CVD. Results were consistent for changes in total MVPA [HR=0.97 (95% CI: 0.95, 0.99)] and MVPA accumulated in >10-minute bouts [HR=0.95 (95% CI: 0.91, 0.98)], with a similar pattern for secondary CVD outcomes. Change in accelerometry-measured MVPA at 1 year and self-reported change in PA at 1 and 4 years were not associated with CVD outcomes. CONCLUSIONS: Increased accelerometry-measured MVPA from baseline to year 4 is associated with decreased risk of CVD outcomes. This suggests the need for long-term engagement in MVPA to reduce the risk of CVD in adults with overweight/obesity and type 2 diabetes.

Objective: To simultaneously investigate the association of diet quality and all-cause mortality in groups with varying cardiometabolic diseases (CMDs) at baseline. Design: From the population-based Lifelines cohort, 40,892 non-underweight participants aged ≥50 years with data on diet quality and confounding factors were included (enrollment 2006-2013). From food frequency questionnaire data, tertiles of the Lifelines diet score were calculated (T1 = poorest, T3 = best diet quality). Four CMD categories were defined: 1) CMD-free, 2) type 2 diabetes, 3) one cardiovascular disease (CVD), 4) two or more CMDs. Months when deaths occurred were obtained from municipal registries up until November 2019. Multivariable Cox proportional hazards models were applied for the total population and stratified by CMD categories. Results: After a median follow-up of 7.6 years, 1,438 participants died. Diet quality and CMD categories were independently associated with all-cause mortality in crude and adjusted models (p < 0.001). A dose-response relationship of diet quality with all-cause mortality was observed in the total population (P for trend < 0.001, T2 vs. T3 = 1.22 (1.07-1.41), T1 vs. T3 = 1.57 (1.37-1.80)). In stratified analyses, the association was significant for CMD-free individuals (T1 vs. T3 = 1.63 (1.38-1.93)) and for type 2 diabetes patients (1.87 (1.17-3.00)), but not for patients with one CVD (1.39 (0.93-2.08)) or multiple CMDs (1.19 (0.80-1.76)). Conclusions: A high-quality diet can potentially lower all-cause mortality risk in the majority of the ageing population. Its effect may be greatest for CMD-free individuals and patients with type 2 diabetes. Tailored dietary guidelines may be required for patients with extensive histories of CMDs.
