Younger people with Type 2 diabetes have poorer self-care practices compared with older people: results from the Australian National Diabetes Audit

Understanding the preferences of young adults with type 2 diabetes mellitus with regard to diabetes self-management education: a qualitative study

AIM

Young-onset type 2 diabetes (YOD) is associated with poorer clinical outcomes. To support the development of more effective diabetes self-management education (DSME) programmes, this study aimed to understand the preferences of young adults with YOD in relation to the modality, content and qualities of DSME.

METHODS

Maximal variation sampling was employed to recruit participants of varied age, ethnicity and marital status. In-depth interviews using a semistructured questionnaire were conducted. Subsequently, thematic analysis with coding and conceptualisation of data was applied to identify the main themes regarding DSME.

RESULTS

21 young adult participants aged 22-39 years were interviewed from three polyclinics in Singapore. The most used modalities for DSME included education from healthcare providers, information and support from family and friends and information from internet sources. Participants were most interested in information regarding diet, age-specific diabetes-related conditions and medication effects. Additionally, participants valued DSME that was credible, accessible, individualised and empathetic. Conversely, absence of the above qualities and stigma hindered participants from receiving DSME.

CONCLUSION

Our study explored the preferences of young adults with YOD with regard to DSME, identifying the most used modalities, preferred content and qualities that were valued by young adults. Our findings will help inform the development of DSME programmes that can better meet the needs and preferences of young adults with YOD.

A theory based study on diabetes self-management in older Chinese adults

Approximately 1 in 3 (or 80 million) Chinese age 60 years or older are living with type 2 diabetes in China. New perspectives are needed to understand the intricate phenomenon of diabetes self-management (DSM) in older Chinese adults. Guided by the expanded Tripartite Model of Self-Management, this study aimed to identify the inter-relationships between the tripartite components simultaneously and their influencing factors. This cross-sectional study included a stratified random sample of 98 community-dwelling adults age 60 or older with type 2 diabetes. Findings revealed distinct predictors for knowledge about DSM, DSM behaviors and coping. There were significant inter-relationships among the tripartite components. The theoretical model was a good fit for the data. This study provides valuable insights into the complex relationships between knowledge about DSM, DSM behaviors, and coping strategies, offering direct implications for improving the health outcomes of older adults with diabetes.

Lower achievement of guideline recommended care in Canadian adults with early-onset diabetes: A population-based cohort study

AIMS

Adults with early-onset diabetes (age < 40 years) have an increased risk of complications, and it is unclear whether they are receiving guideline recommended care. We compared the frequency and results of haemoglobin A1c (HbA1c) testing in adults with early-onset and usual-onset diabetes and assessed factors related to guideline concordance.

METHODS

Population-level databases from Alberta, Canada (∼4.5 million) were used to identify adults with incident diabetes. The cohort was stratified by age at diagnosis (< 40 vs. ≥ 40 years) and then followed for 365 days for HbA1c testing. Adjusted multivariable analyses were used to identify clinical and sociodemographic factors associated with guideline concordance.

RESULTS

Among 23,643 adults with incident diabetes (mean age 54.1 ± 15.4 years; 42.1 % female), 18.9 % had early-onset diabetes. Early-onset diabetes was associated with lower frequency of testing (adjusted odds ratio (aOR), 0.80; 95 % CI 0.70-0.90) and above target glycaemic levels compared to usual-onset diabetes (aOR, 1.45; 95 % CI 1.29-1.64). Factors associated with guideline concordant frequency of HbA1c testing were rural residence and insulin use.

CONCLUSIONS

In our universal care setting with premium-free health care, early-onset diabetes was associated with lower rates of HbA1c testing and sub-optimal glycaemic control compared to those with usual-onset diabetes.

Association between age at diagnosis and all-cause mortality in type 2 diabetes: the Renal Insufficiency and Cardiovascular Events (RIACE) Italian Multicenter Study

AIMS

It is unclear whether type 2 diabetes diagnosed in young adulthood is associated with increased severity than that occurring later in life beyond longer lifetime exposure to hyperglycemia. This study aimed at assessing the independent association of age at type 2 diabetes diagnosis with all-cause mortality.

METHODS

This prospective cohort study enrolled 15,773 Caucasian patients with type 2 diabetes in 19 Italian centers in 2006-2008. Cardiometabolic risk profile and presence of complications and comorbidities were assessed at baseline and participants were stratified by quartiles of age at diabetes diagnosis. All-cause mortality was verified on 31 October 2015.

RESULTS

Valid information on vital status was retrieved for 15,656 participants (99.3%). Patients in the lowest quartile had the longest diabetes duration, the worst glycemic control and the highest prevalence of insulin treatment, obesity, atherogenic dyslipidemia, and smoking habits. All complications were inversely associated with age at diabetes diagnosis after adjustment for age and sex, but not after further adjustment for diabetes duration. Percentages of death, Kaplan-Meier estimates, and unadjusted hazard ratios and mortality rates increased from the lowest to the highest quartile. In contrast, when adjusting for age and sex, participants falling in the lowest quartile, showed the highest mortality risk [hazard ratio 1.321 (95% confidence interval 1.196-1.460), P < 0.0001]. However, differences among quartiles disappeared after adjustment for diabetes duration, complications/comorbidities, or other cardiovascular risk factors.

CONCLUSIONS

Type 2 diabetes onset in young adulthood is associated with increased mortality that is mainly driven by longer diabetes duration favoring the development of complications.

Association Between Age at Diagnosis of Type 2 Diabetes and Hospitalization for Heart Failure: A Population-Based Study

BACKGROUND

The relation between age at diagnosis of type 2 diabetes (T2D) and hospitalization for heart failure (HHF) is unclear. We assessed the association between age at diagnosis of T2D and HHF.

METHODS AND RESULTS

We conducted a population-based cohort study using administrative health databases from the Canadian province of Ontario, including participants without prior heart failure. We identified people with new-onset T2D between April 1, 2005 and March 31, 2015, and matched each person with 3 diabetes-free adults, according to birth year and sex. We estimated adjusted hazard ratios (HRs) and rate ratios (RRs) for the association between age at T2D diagnosis and incident HHF, which was assessed until March 31, 2020. Among 743 053 individuals with T2D and 2 199 539 matched individuals without T2D, 126 241 incident HHF events occurred over 8.9 years. T2D was associated with a greater adjusted hazard of HHF at younger ages (eg, HR at age 30 years: 6.94 [95% CI, 6.54-7.36]) than at older ages (eg, HR at age 60 years: 2.50 [95% CI, 2.45-2.56]) relative to matched individuals. Additional adjustment for mediators (hypertension, coronary artery disease, and chronic kidney disease) marginally attenuated this relationship. Age at T2D diagnosis was associated with a greater number of HHF events relative to matched individuals at younger ages (eg, RR at age 30 years: 6.39 [95% CI, 5.76-7.08]) than at older ages (eg, RR at age 60 years: 2.65 [95% CI, 2.54-2.76]).

CONCLUSIONS

Younger age at T2D diagnosis is associated with a disproportionately elevated HHF risk relative to age-matched individuals without T2D.

Fibrinogen-to-Albumin Ratio and Glucose Metabolic States in Patients With Coronary Heart Disease

This study investigated the relationship between fibrinogen-to-albumin ratio (FAR) and glucose metabolic state in patients with coronary heart disease (CHD). A total of 52,062 patients were enrolled in this study. Patients were classified according to FAR tertiles (T1: FAR < 0.0073; T2: 0.0073 ≤ FAR ≤ 0.0886; T3: FAR ≥ 0.0887). Patients were also classified into the normal glucose regulation (NGR) and elevated blood glucose (EBG) groups. The relationship between FAR and EBG was analyzed using logistic regression, and the association was evaluated according to sex and age. Among the participants, 32,471 (62.4%) had EBG, which was positively associated with FAR (odds ratio [OR], 1.19; 95% confidence interval [CI] 1.15-1.23). The OR of the FAR for EBG in males was higher than that in females (1.25; 95% CI 1.18-1.33 vs 1.15; 95% CI 1.10-1.20). Moreover, the OR of FAR for EBG was greater in patients aged 60 or younger (OR: 1.25; 95% CI 1.18-1.33) than in the elderly patients (over 60 years of age) (OR: 1.15; 95% CI 1.10-1.20). The results indicated a significant relationship between FAR and EBG and this association was higher in males and middle-aged patients.

Diabetes self-care behaviours among people diagnosed with serious mental illness: A cross-sectional correlational study

WHAT IS KNOWN ON THE SUBJECT?: People diagnosed with serious mental illness have a high risk of diabetes and are more likely to develop type 2 diabetes at ages below 60 years. Effective diabetes self-care behaviours among people diagnosed with serious mental illness can improve glycaemic control and reduce vascular complications. Few studies have investigated diabetes self-care behaviours and their associations with health literacy and self-efficacy in people diagnosed with serious mental illness. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Diabetes self-care behaviours in people diagnosed with serious mental illness were suboptimal; the least frequently performed self-care activities were self-monitoring of blood glucose. Factors associated with diabetes self-care behaviours are gender, age, communicative and critical health literacy and self-efficacy. Self-efficacy is the strongest predictor of self-care behaviours among people diagnosed with comorbid serious mental illness and type 2 diabetes. WHAT ARE THE IMPLICATIONS OF PRACTICE?: Mental health nurses should assess diabetes-specific health literacy of people diagnosed with serious mental illness to ensure that they possess the knowledge and skills related to diabetes self-care. When treating young people and those with newly diagnosed type 2 diabetes, nurses should incorporate strategies to minimise their perceptions of diabetes-related distress and increase their confidence in managing comorbid diabetes. ABSTRACT: Introduction People diagnosed with serious mental illness (SMI) experience greater challenges in managing their type 2 diabetes mellitus (T2DM) than do those diagnosed with T2DM alone. Aim This study investigated diabetes self-care activities and the factors associated with these activities in people diagnosed with SMI in a hospital setting. Methods A cross-sectional correlational study was conducted among 126 people diagnosed with comorbid SMI and T2DM in Taipei, Taiwan, between October 2020 and April 2021. Data were collected using self-report questionnaires and a chart review. Three-step hierarchical multiple regression analysis was used to identify factors associated with diabetes self-care behaviours. Results Diabetes self-care behaviours in people diagnosed with SMI were suboptimal overall. Hierarchical multiple regression analyses revealed that age (β = 0.18, p = .037) and self-efficacy (β = 0.27, p = .004) significantly associated with diabetes self-care behaviours. Discussion Self-efficacy is the strongest predictor of self-care behaviours among people diagnosed with comorbid SMI and T2DM. Implications for Practice Mental health professionals should focus on enhancing confidence in managing comorbid diabetes in people diagnosed with comorbid SMI, especially young people and those with newly diagnosed T2DM.

What are the perspectives of adults aged 18-40 living with type 2 diabetes in urban settings towards barriers and opportunities for better health and well-being: a mixed-methods study

OBJECTIVES

Delivered as part of the global assessment of diabetes in urban settings, this study explores different aspects of living with type 2 diabetes, for adults aged 18-40. Primary questions were as follows: (1) can we identify subgroups of adults under 40 years old sharing specific perspectives towards health, well-being and living with type 2 diabetes and (2) do these perspectives reveal specific barriers to and opportunities for better type 2 diabetes prevention and management and improved well-being?

DESIGN

The study employed a mixed-method design with data collected through demographic questionnaires, Q-sort statement sorting exercises, focus groups discussions and individual interviews.

SETTING

Primary care across Greater Manchester, UK.

PARTICIPANTS

Those aged between 18 and 40, with a confirmed type 2 diabetes diagnosis, and living in Greater Manchester were eligible to participate. A total of 46 people completed the Q-sort exercise and 43 were included in the final analysis. Of those, 29 (67%) identified as female and 32 (75%) as white. Most common time since diagnosis was between 5 and 10 years.

RESULTS

The Q-sort analysis categorised 35 of the 43 participants (81%) into five subgroups. Based on average statement sorts for each subgroup, perspectives were characterised as: (1) stressed and calamity coping (n=13), (2) financially disadvantaged and poorly supported (n=12), (3) well-intentioned but not succeeding (n=5), (4) withdrawn and worried (n=2) and (5) young and stigmatised (n=3). Holistic analysis of our qualitative data also identified some common issues across these subgroups.

CONCLUSIONS

Adults under 40 with type 2 diabetes are not a homogeneous group, but fall into five identifiable subgroups. They also experience issues specific to this age group that make it particularly difficult for them to focus on their own health. More tailored support could help them to make the necessary lifestyle changes and manage their type 2 diabetes better.

The Prevalence of Metabolically Unhealthy Normal Weight and Its Influence on the Risk of Diabetes

CONTEXT

Diabetes is a major health problem and metabolically unhealthy is an important risk factor.

OBJECTIVE

To conduct the first nationally representative study on epidemiological data of metabolically unhealthy normal weight (MUNW) focused only on nondiabetic subjects and determine the predictive effect on diabetes in China.

METHODS

A longitudinal study was conducted using data from the Rich Healthcare Group in China. Metabolic status was determined by the revised National Cholesterol Education Program Adult Treatment Panel III criteria, and individuals with 2 or more criteria were categorized as MUNW and diagnosed with metabolic syndrome (MetS) if they met 3 or more.

RESULTS

Of a total of 63 830 nondiabetic normal-weight individuals, 8935 (14.0%) were classified as MUNW and 1916 (3.00%) were diagnosed with MetS. After adjusting for potential confounders, individuals with MUNW had a greater diabetes risk (4.234, 95% CI 3.089-5.803) than those without MUNW during an average of 3.10 years of follow-up. Also, the multivariable-adjusted hazard ratios for developing diabetes were 3.069 (95% CI 1.790-5.263), 7.990 (95% CI 4.668-13.677), and 11.950 (95% CI 6.618-21.579) for participants with 1, 2, and 3 or more components, respectively, compared with those without any components. Further analyses suggested that the number of MetS components present is associated with the risk of diabetes, especially in metabolically unhealthy normal-weight young male adults. Multivariable-adjusted hazard ratios (95% CI) for incident diabetes among individuals with 1, 2, and at least 3 components were 4.45 (1.45-13.72), 9.82 (3.05-31.64), and 15.13 (3.70-61.84) for participants aged ≤44 years, and 3.55 (1.81-6.97), 8.52 (4.34-16.73), and 13.69 (6.51-28.77) for male participants, respectively.

CONCLUSIONS

The prevalence of MUNW is 14% in Chinese normal-weight nondiabetic individuals, and active intervention is necessary for this category of people. The presence of MUNW significantly increases the risk of diabetes, and the risk of diabetes is associated with the number of MetS components present in the patient.

Risk of developing chronic kidney disease in young-onset Type 2 diabetes in Korea

We investigated the risk of developing chronic kidney disease (CKD) in patients with young-onset Type 2 diabetes (YOD, diagnosed age < 40 years). We enrolled 84,384 patients aged 20-64 who started anti-diabetic medication between 2010 and 2011 from the Korea National Health Insurance Sharing Service; patients with Type 1 diabetes or a history of CKD were excluded. Multivariate logistic regression analyses were performed to adjust for YOD-distinct variables and compare the incidence of CKD between YOD and late-onset diabetes (LOD, diagnosed age ≥ 40 years). During the median observation period of 5.16 years (interquartile range: 4.58-5.77 years), 1480 out of 77,039 LOD patients and 34 out of 7345 YOD patients developed CKD. Patients with YOD had distinct baseline characteristics compared with the patients with LOD. The odds ratio of developing CKD in patients with YOD over LOD was 1.70 (95% CI 1.15-2.51) after adjusting clinically distinct variables. The increased CKD odds in YOD compared with LOD was greater in the non-smoking group (OR 2.03, 95% CI 1.26-3.26) than in the smoking group (OR 1.49, 95% CI 0.74-2.98, p = 0.0393 for interaction). Among YOD patients, hypertension (34.76% vs. 64.71%, p = 0.0003), dyslipidemia (46.87% vs. 73.53%, p = 0.0019), and sulfonylurea use (35.54% vs. 52.94%, p = 0.0345) were associated with CKD development. YOD patients have a greater risk of developing CKD than LOD patients after adjusting clinically distinct variables.

Socio-personal factors affecting adherence to treatment in patients with type 2 diabetes: A systematic review and meta-analysis

PURPOSE

The purpose of study was to identify the socio-personal factors affecting adherence to the treatment of patients with type 2 diabetes.

METHODS

Cross-sectional articles were extracted from databases such as Web of Science, PubMed, Elsevier. A meta-analysis was performed using integrated odds ratios (OR) and 95% confidence interval (CIs) for age, BMI, depression, educational level, gender, employment status, marital status, smoking status. STATA 12.0 was used to estimate pooled RR in definite subgroups. The quality of the studies included was evaluated using the STROBE checklist.

RESULTS

Thirty-one studies out of 7407 extracted articles were finally selected for the meta-analysis. The results showed that younger people had a 17% higher risk than older people, smokers had a 22% higher risk than non-smokers, and the employed had a 15% higher risk of non-adherence to treatment.

CONCLUSION

In conclusion, older age, smoking and employment can lead to non-adherence to T2D treatment. Interventions are suggested to be made besides common health care considering the socio-personal features on type 2 diabetes patients' treatment adherence.

Multimorbidity, Polypharmacy, Severe Hypoglycemia, and Glycemic Control in Patients Using Glucose-Lowering Drugs for Type 2 Diabetes: A Retrospective Cohort Study Using Health Insurance Claims in Japan

INTRODUCTION

This study aimed to understand the actual status of multimorbidity and polypharmacy among patients with type 2 diabetes using glucose-lowering drugs, and to assess the effects of patient characteristics on severe hypoglycemia and glycemic control.

METHODS

We designed a retrospective cohort study using health insurance claims and medical checkup data in Japan from April 2016 to February 2021 and identified patients with type 2 diabetes who were prescribed glucose-lowering drugs. We analyzed data on patient characteristics, including multimorbidity and polypharmacy, calculated the incidence rate for severe hypoglycemic events, applied a negative binomial regression model to explore factors that affected severe hypoglycemia, and analyzed the status of glycemic control in the subcohort for which HbA1c data were available.

RESULTS

Within the analysis population (n = 93,801), multimorbidity was present in 85.5% and mean ± standard deviation for oral drug prescriptions was 5.6 ± 3.5 per patient, while for those aged 75 years or older these numbers increased to 96.3% and 7.1 ± 3.5, respectively. The crude incidence rate for severe hypoglycemia was 5.85 (95% confidence interval 5.37, 6.37) per 1000 person-years. Risk factors for severe hypoglycemia included younger and older age, prior severe hypoglycemia, use of insulin, sulfonylurea, two-drug therapy including sulfonylurea or glinides, three-or-more-drug therapy, excessive polypharmacy, and comorbidities including end-stage renal disease (ESRD) requiring dialysis. Subcohort analysis (n = 26,746) showed that glycemic control is not always maintained according to guidelines.

CONCLUSION

Patients with type 2 diabetes, particularly older patients, experienced high multimorbidity and polypharmacy. Several risk factors for severe hypoglycemia were identified, most notably younger age, ESRD, history of severe hypoglycemia, and insulin therapy.

Wounds under diabetic milieu: The role of immune cellar components and signaling pathways

A major challenge in the field of diabetic wound healing is to confirm the body's intrinsic mechanism that could sense the immune system damage promptly and protect the wound from non-healing. Accumulating literature indicates that macrophage, a contributor to prolonged inflammation occurring at the wound site, might play such a role in hindering wound healing. Likewise, other immune cell dysfunctions, such as persistent neutrophils and T cell infection, may also lead to persistent oxidative stress and inflammatory reaction during diabetic wound healing. In this article, we discuss recent advances in the immune cellular components in wounds under the diabetic milieu, and the role of key signaling mechanisms that compromise the function of immune cells leading to persistent wound non-healing.

Characteristics and care of young people with type 2 diabetes included in the national diabetes audit datasets for England

INTRODUCTION

We report contemporary age-related prevalence, characteristics and care of children and young people with type 2 diabetes in England.

METHODS

Individuals with a recorded diagnosis of type 2 diabetes between January 2019 and March 2020 were identified from a whole population register. Age, sex, ethnicity, deprivation quintile, weight, HbA_1c and receipt of the nine National Institute for Health & Care Excellence (NICE) recommended annual care processes were extracted from electronic clinical records and analysed by pre-specified age bands.

RESULTS

In total, 122,780 (4.6%) of 2,642,435 individuals in England with type 2 diabetes were aged under 40 years, comprising; 650 (0.5%) under 16 years, 910 (0.7%) aged 16-18 years, 8245 (6.7%) aged 19-25 and 112,975 (92%) aged 26-39 years. Compared to people with type 2 diabetes aged above 40 years, young people were significantly more likely to be from minority ethnic groups: 51% under 16 years, 41% 16-18 years, 38% 19-25 years, 38% 26-39 years, 27% 40-59 years and 15% 60-79 years were of Black or Asian ethnicity. In addition, those aged under 40 years were more likely to be obese, women, to live in the most-deprived socioeconomic areas and less likely to receive the NICE recommended annual care processes or achieve target HbA_1c .

INTERPRETATION

The substantial number of people under 40 years of age with type 2 diabetes, are more likely to have characteristics associated with inequalities and are less likely to achieve HbA_1c targets and receive recommended care processes. These findings highlight the need to consider novel approaches to service provision for this high-risk group.

Prevalence and risk of diabetic complications in young-onset versus late-onset type 2 diabetes mellitus

AIMS

To compare the prevalence and risk of diabetic complications between people with young-onset and late-onset type 2 diabetes mellitus (T2DM).

METHODS

In this observational study, 10,447 people with T2DM had at least one study of diabetic complications: retinopathy, neuropathy, chronic kidney disease (CKD), carotid artery plaque. We use odds ratios to compare complications between young-onset T2DM (YOD) and late-onset T2DM (LOD).

RESULTS

We compare 1,791 people with YOD (diagnosed < 40 years) and 8,656 with LOD (diagnosed ≥ 40 years). The YOD had a higher prevalence of these complications than the LOD (p < 0.011) after adjustment for confounding factors. Further adjustment for diabetes duration greatly attenuated the odds ratios however, neuropathy remained significantly more frequent in people with YOD (adjusted odds ratio: 1.39, 95% confidence interval: 1.13-1.71, p = 002). In cluster analysis on the 2,126 study participants who were diagnosed with T2DM within the previous two years, 47% of the YOD group were in the severe insulin-deficient diabetes cluster in comparison to 23% LOD; 28% and 44% respectively were in the mild age-related diabetes.

CONCLUSION

People with YOD had a higher prevalence of complications than those with LOD, but this was mostly attributed to a longer duration of diabetes. However, the prevalence of neuropathy remained significantly higher even after adjusting for factors including the duration of diabetes.

Developing services to support the delivery of care to people with early-onset type 2 diabetes

Early-onset type 2 diabetes occurring in childhood or early adulthood carries a significant excess burden of microvascular diabetes complications, cardiovascular disease and premature death, compared to later onset type 2 diabetes along with adverse pregnancy outcomes in women of child-bearing age. National audit data in England reveal that 122,780 individuals under the age of 40 years are currently living with type 2 diabetes, with an over-representation of people from minority ethnicities and those in the most socioeconomically deprived quintiles. A diagnosis of type 2 diabetes earlier in life poses some unique challenges to healthcare providers that are not routinely encountered when type 2 diabetes presents later. These include; (1) the need to ensure correct diabetes classification in an age group that carries a higher probability of other types of diabetes, (2) overcoming difficulties in engaging with individuals who are of working age or in full-time education, (3) appreciating and addressing the lower attainment of diabetes treatment targets and (4) proactively supporting women of child-bearing age to optimise their future pregnancy outcomes through better preparation for pregnancy, including achieving optimum glycaemic control at the time of conception. Meanwhile, approaches to prevent type 2 diabetes in younger age groups are challenged by difficulties in identifying those at highest risk, by poorer attendance at lifestyle interventions to prevent or delay the onset of type 2 diabetes and by attenuation of associated weight loss in those that do attend. In this article, we discuss the importance of recognising and addressing the distinct challenges in delivering healthcare to those with early-onset type 2 diabetes, the greater challenges in preventing type 2 diabetes at younger ages, and key components of strategies that might address these challenges to drive improvements in pregnancy outcomes, microvascular and cardiovascular outcomes.

Characteristics of Glycemic Control and Long-Term Complications in Patients with Young-Onset Type 2 Diabetes

BACKGRUOUND

The prevalence of young-onset diabetes (YOD) has been increasing worldwide. As the incidence of YOD increases, it is necessary to determine the characteristics of YOD and the factors that influence its development and associated complications.

METHODS

In this retrospective study, we recruited patients who were diagnosed with type 2 diabetes mellitus between June 2001 and December 2021 at a tertiary hospital. The study population was categorized according to age: YOD (age <40 years), middle-age-onset diabetes (MOD, 40≤ age <65 years), and late-onset diabetes (LOD, age ≥65 years). We examined trends in glycemic control by analyzing fasting glucose levels during the first year in each age group. A Cox proportional-hazards model was used to determine the relative risk of developing complications according to glycemic control trends.

RESULTS

The fasting glucose level at the time of diagnosis was highest in the YOD group (YOD 149±65 mg/dL; MOD 143±54 mg/dL; and LOD 140±55 mg/dL; p=0.009). In the YOD group, glucose levels decreased at 3 months, but increased by 12 months. YOD patients and those with poor glycemic control in the first year were at a higher risk of developing complications, whereas the risk in patients with LOD was not statistically significant.

CONCLUSION

YOD patients had higher glucose levels at diagnosis, and their glycemic control was poorly maintained. As poor glycemic control can influence the development of complications, especially in young patients, intensive treatment is necessary for patients with YOD.

Frailty in Community-Dwelling Adults Aged 40 Years and over with Type 2 Diabetes: Association with Self-Management Behaviors

Background: Evidence is lacking on risk factors for frailty and prefrailty and their relationship with self-management behaviors in patients ≥40 years of age with type 2 diabetes. Methods: Participants were selected as a cross-sectional cohort at five communities in Shanghai, China during January−March 2021. The modified FRAIL scale and the Summary of Diabetes Self-Care Activities (SDSCA) measure were used. Results: Of the 558 participants, 10.2% were classified as frailty and 34.1% as prefrailty. The prevalence of frailty was higher in males than in females (p = 0.009), whereas females were associated with higher odds of prefrailty (aOR 1.67, 95% CI [1.08−2.60]). Multimorbidity, ≥3 chronic diseases, and hospitalization in the past year were considered risk factors for both frailty and prefrailty. Each point earned on SDSCA and physical activity were associated with lower odds of frailty (aOR 0.95, 95% CI [0.92−0.98]) and prefrailty (aOR 0.52, 95% CI [0.31−0.85]), respectively. Frail participants performed significantly worse self-care practice than prefrail and non-frail ones, especially on diet, physical activity, and medication adherence (p < 0.001). Conclusions: Frail patients ≥40 years of age with type 2 diabetes reported poorer self-care performance. Further interventional studies are warranted to clarify their causal relationship.

Obesity Fact Sheet in Korea, 2021: Trends in Obesity Prevalence and Obesity-Related Comorbidity Incidence Stratified by Age from 2009 to 2019

Background

The global public health burden of obesity has increased with socio-economic development. The Korean Society for the Study of Obesity released the 2021 Obesity Fact Sheet to address trends in obesity prevalence and comorbid conditions by different age groups.

Methods

Individuals ≥20 years old who underwent a health checkup provided by the Korean National Health Insurance Service between 2009 and 2019 were included. The prevalence of obesity and abdominal obesity was standardized by age and sex based on the 2010 population and housing census. The incidence of obesity-related comorbidities was tracked from 2009 to 2019, and the incidence per 1,000 person-years was calculated using Poisson regression adjusted for age and sex.

Results

Obesity and abdominal obesity prevalence has increased for the entire population over the past 11 years. Obesity prevalence has risen rapidly in individuals in their 20s and 80s compared with other age groups. Additionally, class III obesity prevalence in both men and women has significantly increased by nearly threefold. The relative risk of developing type 2 diabetes, myocardial infarction, ischemic stroke, and cancers in people with obesity or abdominal obesity is greater than in people without obesity or abdominal obesity. The relative risk was higher in young and middle-aged individuals than in the older population.

Conclusion

The findings based on the 2021 Obesity Fact Sheet suggest the need to better understand obesity characteristics according to age and sex and to establish individualized treatment strategies.

Association of Age of Metabolic Syndrome Onset With Cardiovascular Diseases: The Kailuan Study

BACKGROUND

Metabolic syndrome (MetS) is associated with an increased risk of incident cardiovascular diseases (CVD), but the association between the new-onset MetS at different ages and the CVD risk remain unclear.

METHODS

This was a prospective study comprising a total of 72,986 participants without MetS and CVD who participated in the Kailuan study baseline survey (July 2006 to October 2007). All participants received the biennial follow-up visit until December 31, 2019. In addition, 26,411 patients with new-onset MetS were identified from follow-up, and one control participant was randomly selected for each of them as a match for age ( ± 1 year) and sex. In the end, a total of 25,125 case-control pairs were involved. Moreover, the Cox proportional hazard model was established to calculate the hazard ratios (HR) for incident CVD across the onset age groups.

RESULTS

According to the median follow-up for 8.47 years, 2,319 cases of incident CVD occurred. As MetS onset age increased, CVD hazards gradually decreased after adjusting for potential confounders. Compared with non-MetS controls, the HR and the 95% confidence interval (CI) for CVD were 1.84 (1.31-2.57) in the MetS onset age <45 years group, 1.67 (1.42-1.95) for the 45-54 years group, 1.36 (1.18-1.58) for the 55-64 years group, and 1.28 (1.10-1.50) for the ≥65 years group, respectively (p for interaction = 0.03).

CONCLUSIONS

The relative risks of CVD differed across MetS onset age groups, and the associations was more intense in the MetS onset group at a younger age.

Patients' attitudes and intentions towards taking medical advice for type 2 diabetes mellitus: a theory of planned behaviour analysis

PURPOSE

A key component of effective diabetes care is understanding patients' perceptions about diabetes management. Patients' attitudes and intentions towards taking medical advice may predict the outcomes for effective diabetes care. This study aims to measure participants' attitudes, beliefs and intentions towards following medical advice to manage their diabetes using the Theory of Planned Behaviour (TPB). The domains of the TPB are correlated with clinical measures of diabetes to determine if these attitudes and intentions are predictive of better diabetes control.

METHODS

A pilot study was conducted. A 34-item survey was designed using the Theory of Planned Behaviour (TPB) framework and administered via mail by four general practice clinics. Included participants (N = 104; response rate 29.5%) had a diagnosis of type 2 diabetes and were taking medication for glycaemic control. Scores for each domain of the TPB survey were correlated with participants' clinical indicators for diabetes: HbA1c, blood pressure, lipid profile, cholesterol, and kidney health (eGFR and albumin: creatinine ratio) and BMI.

RESULTS

Participants surveyed generally reported positive attitudes and intention to follow medical advice. Medical advice was perceived to be beneficial and useful by the majority. However, in general, there was no correlation between positive intentions and improved clinical indicators of disease. Clinical indicators did not improve with duration of illness. The burden of illness is likely a mitigating factor for positive intention as participants perceive medical advice as difficult and inconvenient to follow.

CONCLUSIONS

Patients' individual capacity to implement medical advice should be addressed in shared-decision making models to potentially improve patient outcomes towards therapeutic targets.

Young-onset type 2 diabetes in South Korea: a review of the current status and unmet need

The prevalence of young-onset (diagnosis at age < 40 years) type 2 diabetes mellitus (T2DM) is increasing globally. Young-onset T2DM has a common pathophysiology of glucose dysregulation as in late-onset T2DM. However, it presents a greater association with obesity and a more rapid decline in β-cell function than late-onset T2DM. Accumulating evidence indicates that disease progression in young-onset T2DM is rapid, resulting in early and frequent development of microvascular and macrovascular complications, as well as premature death. Improper management and low adherence to medical therapy are important issues in young-onset T2DM. This review discusses the epidemiology, disease entity, and clinical issues associated with young-onset T2DM. We also present the prevalence and clinical characteristics of patients with young-onset T2DM in South Korea.

What Gets Measured Gets Improved-Setting Standards and Accreditation for Quality Improvement for Diabetes Services in Australia

The purpose of this article is to illustrate that setting standards of care is the cornerstone for excellence in diabetes management. This is underpinned by 3 activities: a standards and accreditation process, an audit and benchmarking program and a linked quality improvement plan. While there are many examples of local auditing and quality improvement programs, there are very few that are at a national level. The National Association of Diabetes Centres (NADC) was formed by the Australian Diabetes Society and the Australian Diabetes Educators Association to set standards of diabetes care in Australia. A rigorous accreditation process was put in place to recognize primary, secondary, and tertiary level diabetes centers that meet these standards. The NADC accreditation process is underpinned by a quality improvement plan, which must be submitted for accreditation to be granted and is informed by the Australian National Diabetes Audit (ANDA). ANDA is conducted annually to gather information about treatments, complications, self-care practices and quality of life outcomes and provides a national as well as an individual report to the participating center that is used to benchmark against other like centers. The ANDA reports are important to inform national policy and advocacy for diabetes care and to also provide information for quality improvement purposes for the individual participating center. We believe that the NADC Standards and Accreditation can be an exemplar for other countries to adapt and adopt to standardize diabetes care at the highest level.

Associations of Type 2 Diabetes Onset Age With Cardiovascular Disease and Mortality: The Kailuan Study

OBJECTIVE

We aimed to explore the associations between type 2 diabetes onset age and cardiovascular disease (CVD) and all-cause mortality in the Chinese population.

RESEARCH DESIGN AND METHODS

This study included 101,080 participants free of prevalent diabetes and CVD at baseline from the Kailuan Study. All participants were monitored biennially until 31 December 2017. During follow-up, 11,384 participants were diagnosed as having type 2 diabetes. For each case subject, one control subject was randomly selected, matched for age (± 1 years) and sex. The final analysis comprised 10,777 case-control pairs. Weighted Cox regression models were used to evaluate the average hazard ratios (AHRs) and 95% CIs of incident CVD and all-cause mortality among patients with new-onset type 2 diabetes versus control subjects across age-groups.

RESULTS

During a median follow-up of 5.57 years, 1,794 incident events (907 CVD events, of which there were 725 strokes and 887 deaths) occurred. After adjustment for potential confounders, participants with type 2 diabetes diagnosed at age <45 years had the highest relative risks of CVD and all-cause mortality relative to the matched control subjects, with AHRs of 3.21 (95% CI 1.18-8.72) for CVD, 2.99 (95% CI 1.01-9.17) for stroke, and 4.79 (95% CI 1.95-11.76) for all-cause mortality. The risks gradually attenuated with each decade increase in type 2 diabetes onset age.

CONCLUSIONS

The relative risks of CVD and all-cause mortality differed across type 2 diabetes onset age-groups, and the associations were more evident in younger-onset type 2 diabetes.

Impact of age at type 2 diabetes mellitus diagnosis on mortality and vascular complications: systematic review and meta-analyses

AIMS/HYPOTHESIS

Few studies examine the association between age at diagnosis and subsequent complications from type 2 diabetes. This paper aims to summarise the risk of mortality, macrovascular complications and microvascular complications associated with age at diagnosis of type 2 diabetes.

METHODS

Data were sourced from MEDLINE and All EBM (Evidence Based Medicine) databases from inception to July 2018. Observational studies, investigating the effect of age at diabetes diagnosis on macrovascular and microvascular diabetes complications in adults with type 2 diabetes were selected according to pre-specified criteria. Two investigators independently extracted data and evaluated all studies. If data were not reported in a comparable format, data were obtained from authors, presented as minimally adjusted ORs (and 95% CIs) per 1 year increase in age at diabetes diagnosis, adjusted for current age for each outcome of interest. The study protocol was recorded with PROSPERO International Prospective Register of Systematic Reviews (CRD42016043593).

RESULTS

Data from 26 observational studies comprising 1,325,493 individuals from 30 countries were included. Random-effects meta-analyses with inverse variance weighting were used to obtain the pooled ORs. Age at diabetes diagnosis was inversely associated with risk of all-cause mortality and macrovascular and microvascular disease (all p < 0.001). Each 1 year increase in age at diabetes diagnosis was associated with a 4%, 3% and 5% decreased risk of all-cause mortality, macrovascular disease and microvascular disease, respectively, adjusted for current age. The effects were consistent for the individual components of the composite outcomes (all p < 0.001).

CONCLUSIONS/INTERPRETATION

Younger, rather than older, age at diabetes diagnosis was associated with higher risk of mortality and vascular disease. Early and sustained interventions to delay type 2 diabetes onset and improve blood glucose levels and cardiovascular risk profiles of those already diagnosed are essential to reduce morbidity and mortality.

Self-care in Iranian patients with diabetes: A systematic review and meta-analysis

OBJECTIVES

Self-care is a major factor in managing diabetes. This study aimed to determine the self-care status of Iranian patients with diabetes and to estimate the percentage of self-care in these individuals through a systematic review and meta-analysis.

METHODS

In this systematic review and meta-analysis 53 domestic articles published in Farsi and English were evaluated. We conducted database searches in domestic and foreign databases of Scientific Information Database (SID), MagIran, Google Scholar, Web of Science, Pub Med, and Scopus with no time limit. Data analysis was performed in Stata version 12 using meta-analysis method and the random effects model.

RESULTS

A total of 50 articles (53 groups) with a sample size of 9565 were systematically reviewed. The percentage of self-care in patients with diabetes was reported to be 48.86 (95% confidence interval [CI]: 43.79-53.94). According to the results, the percentage of self-care score was higher in patients with type I diabetes (55.53) when compared with patients with type II diabetes (49.26).

CONCLUSIONS

Since patients with diabetes obtained only half of the self-care score and given the importance of self-care in controlling and treating diabetes, it is necessary to perform actions to improve self-care such as benefiting from health facilities, and social and family support.

Association of Cardiometabolic Multimorbidity and Depression With Cardiovascular Events in Early-Onset Adult Type 2 Diabetes: A Multiethnic Study in the U.S

OBJECTIVE

To evaluate the temporal patterns of cardiometabolic multimorbidity (CM) and depression in White Caucasians (WCs) and African Americans (AAs) with early-onset type 2 diabetes and their impact on long-term atherosclerotic cardiovascular disease (ASCVD).

RESEARCH DESIGN AND METHODS

From U.S. electronic medical records, 101,104 AA and 505,336 WC subjects with type 2 diabetes diagnosed between 2000 and 2017 were identified (mean follow-up 5.3 years). Among those without ASCVD at diagnosis, risk of ASCVD and three-point major adverse cardiovascular events (MACE-3) (heart failure, myocardial infarction, or stroke) was evaluated between ethnicities by age-groups.

RESULTS

The proportion of patients diagnosed at <50 years of age increased during 2012-2017 (AA 34-38%, WC 26-29%). Depression prevalence increased during 2000-2017 (AA 15-23%, WC 20-34%), with an increasing trend for CM at diagnosis in both groups. Compared with WC, the adjusted MACE-3 risk was significantly higher in AA across all age-groups, more pronounced in the 18-39-year age-group (hazard ratio 95% CI 1.42, 1.88), and in patients with and without depression. AAs had a 17% (1.05, 1.31) significantly higher adjusted ASCVD risk in the 18-39-year age-group only. Depression was independently associated with ASCVD and MACE-3 risk in both ethnic groups across all age-groups. Other comorbidities were independently associated with ASCVD and MACE-3 risk only among WCs.

CONCLUSIONS

AAs have higher cardiovascular risk compared with WCs, particularly in early-onset type 2 diabetes. CM and depression at diabetes diagnosis have been increasing over the past two decades in both ethnic groups. Strategies for screening and optimal management of CM and depression, particularly in early-onset type 2 diabetes, may result in a lower cardiovascular risk.

Adults with early-onset type 2 diabetes (aged 18-39 years) are severely underrepresented in diabetes clinical research trials

AIMS/HYPOTHESIS

Early-onset adult type 2 diabetes (diagnosed between ages 18 and 39 years) is increasingly prevalent and associated with poor long-term outcomes. We hypothesised that individuals with early-onset adult type 2 diabetes were underrepresented in the prominent research trials that underpin type 2 diabetes management guidelines.

METHODS

We reviewed the mean age of the study populations recruited to 90 prominent trials in type 2 diabetes, including 37 cardio-renal outcomes trials across a range of pharmacological, non-pharmacological and multifactorial interventions, 28 trials from the phase III programmes of three representative glucose-lowering therapies used routinely in clinical practice (empagliflozin, liraglutide and sitagliptin) and 25 prominent trials of diabetes self-management education and support or intensive lifestyle interventions (diet or supervised exercise training). We then estimated the number of individuals within these trials who were aged between 18 and 39 years.

RESULTS

Across all 90 trials, the mean age of 268,978 participants was 63 years (range 51-69 years in individual trials). In 73 trials (81%), <5% of participants were estimated to be aged 18-39 years, despite this age group representing ~15-20% of the adult type 2 diabetes population. Twenty-nine of these trials (32%; total 164,953 participants) excluded individuals below 40 years of age altogether.

CONCLUSIONS/INTERPRETATION

Guidelines for early-onset adult type 2 diabetes are extrapolated predominantly from evidence in older individuals. Strategies to support the participation of individuals with early-onset adult type 2 diabetes in future research are imperative to ensure guidelines for these high-risk individuals are evidence-based.

Prevalence and factors associated with lower limb amputation in individuals with type II diabetes mellitus in a referral hospital in Fortaleza, Ceará, Brazil: A hospital-based cross-sectional study

AIMS

To analyze the association between demographic, socioeconomic, clinical, epidemiological, and primary healthcare factors with the severity of lower limb amputations (LLAs) in individuals with type II diabetes mellitus (DM-II) at a reference hospital in Fortaleza, Ceará, in Northeast Brazil.

METHODS

A cross-sectional study was performed with a representative sample of individuals hospitalized with DM-II and the degree of LLA severity: (1) toes; (2) transmetatarsal or infrapatellar; (3) suprapatellar; (4) disarticulation or bilateral. Potentially associated factors with the outcome degree of amputation severity were identified in a semi-structured evaluation during hospitalization. The prevalence ratios of the degree of amputation severity as a function of associated factors were calculated with robust variance Poisson regression models.

RESULTS

The prevalence of high degree of severity in amputations (suprapatellar, with disarticulation or bilateral) was high in the total sample of 385 patients, revealing to be 49% (187/385). Prevalence ratios (PR) indicated a higher prevalence of DM-II amputation severity in patients who lacked of specific guidance on DM-II amputation in primary care (PR = 1.52, 95% CI: 1.05-2.21).

CONCLUSIONS

LLAs in DM-II were associated with age above 67 years, male gender, cardiovascular disease, and low support for guidance at the primary healthcare level.

Clinical factors associated with persistently poor diabetes control in the Veterans Health Administration: A nationwide cohort study

OBJECTIVE

Patients with persistent poorly-controlled diabetes mellitus (PPDM) despite engagement in clinic-based care are at particularly high risk for diabetes complications and costs. Understanding this population's demographics, comorbidities and care utilization could guide strategies to address PPDM. We characterized factors associated with PPDM in a large sample of Veterans with type 2 diabetes.

METHODS

We identified a cohort of Veterans with medically treated type 2 diabetes, who received Veterans Health Administration primary care during fiscal years 2012 and 2013. PPDM was defined by hemoglobin A1c levels uniformly >8.5% during fiscal year (FY) 2012, despite engagement with care during this period. We used FY 2012 demographic, comorbidity and medication data to describe PPDM in relation to better-controlled diabetes patients and created multivariable models to examine associations between clinical factors and PPDM. We also constructed multivariable models to explore the association between PPDM and FY 2013 care utilization.

RESULTS

In our cohort of diabetes patients (n = 435,820), 12% met criteria for PPDM. Patients with PPDM were younger than better-controlled patients, less often married, and more often Black/African-American and Hispanic or Latino/Latina. Of included comorbidities, only retinopathy (OR 1.68, 95% confidence interval (CI): 1.63,1.73) and nephropathy (OR 1.26, 95% CI: 1.19,1.34) demonstrated clinically significant associations with PPDM. Complex insulin regimens such as premixed (OR 10.80, 95% CI: 10.11,11.54) and prandial-containing regimens (OR 18.74, 95% CI: 17.73,19.81) were strongly associated with PPDM. Patients with PPDM had higher care utilization, particularly endocrinology care (RR 3.56, 95% CI: 3.47,3.66); although only 26.4% of patients saw endocrinology overall.

CONCLUSION

PPDM is strongly associated with complex diabetes regimens, although heterogeneity in care utilization exists. While there is evidence of underutilization, inadequacy of available care may also contribute to PPDM. Our findings should inform tailored approaches to meet the needs of PPDM, who are among the highest-risk, highest-cost patients with diabetes.
