Obesity and Its Association with Undiagnosed Diabetes Mellitus, High Blood Pressure and Hypercholesterolemia in the Malaysian Adult Population: A National Cross-Sectional Study Using NHMS Data

This study aimed to report the prevalence of obesity, classified using Asian cut-off, and its relationships with undiagnosed diabetes mellitus, high blood pressure, and hypercholesteremia. We analyzed the nationally representative data from 14,025 Malaysian adults who participated in the NHMS 2015. The relationship between obesity and undiagnosed diabetes mellitus, high blood pressure, and hypercholesteremia was determined using multivariable logistic regressions, and lifestyle risk factors and sociodemographic characteristics were adjusted. The undiagnosed high blood pressure group showed the highest proportionate of overweight/obese (80.0%, 95% CI: 78.1-81.8) and central obesity (61.8%, 95% CI: 59.3-64.2). Inverse association was observed between underweight with undiagnosed high blood pressure (aOR: 0.40, 95% CI: 0.26-0.61) and hypercholesterolemia (aOR: 0.75, 95% CI: 0.59-0.95) groups. In contrast, positive relationships were shown between overweight/obese and risk of undiagnosed diabetes mellitus (aOR: 1.65, 95% CI: 1.31-2.07), high blood pressure (aOR: 3.08, 95% CI: 2.60-3.63), and hypercholesterolemia (aOR: 1.37, 95% CI: 1.22-1.53). Likewise, central obesity was positively associated with a risk of undiagnosed diabetes mellitus (aOR: 1.40, 95% CI: 1.17-1.67), high blood pressure (aOR: 2.83, 95% CI: 2.45-3.26), and hypercholesterolemia (aOR: 1.26, 95% CI: 1.12-1.42). Our findings indicated the importance of periodical health examinations to assess the risk of non-communicable diseases among the general and abdominal obese Malaysian adults.

Identifying Adult Population at Risk for Undiagnosed Diabetes Mellitus in Medan City, Indonesia Targeted on Diabetes Prevention

Background

Diabetes mellitus is a health problem in Indonesia, where its prevalence rises annually. The condition may negatively impact one's quality of life and lead to significant complications-over 50% of patients with type 2 diabetes mellitus, the most common diabetes type worldwide. To implement diabetic prevention interventions and achieve effective diabetes mellitus control, screening for undiagnosed diabetes mellitus in high-risk populations is essential.

Objective

This study aimed to identify people at risk for undiagnosed diabetes mellitus using the Finnish Diabetes Risk Score (FINDRISC) and oral glucose tolerance test (OGTT).

Methods

This cross-sectional study was carried out, which involved 300 people in Medan City between the ages of 30-75. The study was conducted between July 14 and October 20, 2020. The Finnish Diabetes Risk Score and anthropometric measurements (weight, height, and waist circumference) were used to evaluate each respondent. Low, medium, and high-risk outcome categories were created. All responders underwent oral glucose tolerance tests, with results classified as normal, prediabetes, or diabetes. The Chi-square test was used to examine the data and identify potential risk variables for diabetes mellitus.

Results

Of 300 individuals, 91.7% were female, and 8.3% were male. 33.7% of participants had a low risk of acquiring diabetes, 55.0% had an intermediate risk, and 11.3% had a high risk. 70% of participants who took an oral glucose tolerance test had blood glucose levels that were normal (less than 100 mg/dl), 18.7% had blood glucose levels suggestive of prediabetes (between 100 and 125 mg/dl), and 11.3% had blood glucose levels suggestive of diabetes (126 mg/dl or higher). Ages 54 to 64 years and older, high body mass index and central obesity, a lack of vegetables and fruits in the daily diet, inactivity, uncontrolled hypertension, a history of hyperglycemia, and a family history of diabetes were all linked to a significant increase in the risk of developing diabetes. Most respondents at low risk of developing type 2 diabetes had normal blood sugar levels, while those at high risk of developing type 2 diabetes had high blood glucose levels (p = 0.005).

Conclusion

Oral glucose tolerance testing and the FINDRISC questionnaire may be used to identify individuals who are at high risk for developing diabetes and to encourage them to adopt healthy behaviours.

Risk Factors of Undiagnosed Diabetes Mellitus among Korean Adults: A National Cross-Sectional Study Using the KNHANES Data

In this cross-sectional study, we investigated the baseline risk factors of diabetes mellitus (DM) in patients with undiagnosed DM (UDM). We utilized the Korean National Health and Nutrition Examination Survey (KNHANES) 2010–2017 data. Data regarding the participants’ demographic characteristics, health status, health determinants, healthcare accessibility, and laboratory tests were gathered to explore the differences between the DM, UDM, and without-DM groups. Among the 64,759 individuals who participated in the KNHANES 2010–2017, 32,611 individuals aged ≥20 years with fasting plasma glucose levels of <100 or ≥126 mg/dL were selected. The odds ratios (ORs) regarding family history of diabetes and the performance of national health and cancer screening tests were lower in the UDM group than in the DM group (adjusted OR: 0.54; 95% confidence interval (CI): 0.43, 0.66; adjusted OR: 0.74; 95% CI: 0.62, 0.89; adjusted OR: 0.71; 95% CI: 0.60, 0.85). The ORs of hypertension and obesity were higher in the UDM group than in the DM group (adjusted OR: 1.32; 95% CI: 1.06, 1.64; adjusted OR: 1.80; 95% CI: 1.37, 2.36, respectively). Patients with UDM were more likely to be exposed to DM-related risk factors than those with and without DM. Public health interventions to prevent UDM development are necessary.

Screening Model for Estimating Undiagnosed Diabetes among People with a Family History of Diabetes Mellitus: A KNHANES-Based Study

A screening model for estimating undiagnosed diabetes mellitus (UDM) is important for early medical care. There is minimal research and a serious lack of screening models for people with a family history of diabetes (FHD), especially one which incorporates gender characteristics. Therefore, the primary objective of our study was to develop a screening model for estimating UDM among people with FHD and enable its validation. We used data from the Korean National Health and Nutrition Examination Survey (KNHANES). KNAHNES (2010-2016) was used as a developmental cohort (n = 5939) and was then evaluated in a validation cohort (n = 1047) KNHANES (2017). We developed the screening model for UDM in male (SMM), female (SMF), and male and female combined (SMP) with FHD using backward stepwise logistic regression analysis. The SMM and SMF showed an appropriate performance (area under curve (AUC) = 76.2% and 77.9%) compared with SMP (AUC = 72.9%) in the validation cohort. Consequently, simple screening models were developed and validated, for the estimation of UDM among patients in the FHD group, which is expected to reduce the burden on the national health care system.

Evaluation of the value of diabetes risk scores in screening for undiagnosed diabetes and prediabetes: a community-based study in southwestern China

OBJECTIVES

To evaluate the performance and cost-effectiveness of existing diabetes risk scores (DRSs) to screen for undiagnosed diabetes mellitus (UDM) and prediabetes (PD) in a community-based southwestern Chinese population.

METHODS

Participants in TIDE-Chengdu survey with requisite data and without known diabetes were included. Five Chinese-derived DRSs and six non-Chinese-derived DRSs were included for evaluation. Their performance in detecting UDM and UMD or PD (UDM/PD) was assessed using the C-statistic. The cost-effectiveness of the optimal DRS was compared with that of capillary fasting blood glucose (CFBG).

RESULTS

Of the 1,692 TIDE-Chengdu survey participants included, 177 (10.5%) had UDM and 339 (20.0%) had PD. The rural participants (N = 737) were more likely to have UDM (13.4% vs. 8.2%) and PD (24.8% vs. 16.3%) than their urban counterparts (N = 955) (P < 0.0001). In the full population, the included DRSs all showed good discrimination in detecting UDM (C-statistic: 0.699 to 0.762) and UDM/PD (C-statistic: 0.717 to 0.769), but the New Chinese DRS (NCDRS) performed best for both UDM and UDM/PD. The DRSs evaluated all showed better performance in urban participants than rural participants for both UDM (C-statistic: 0.718 to 0.795 vs. 0.642 to 0.720) and UDM/PD (C-statistic: 0.729 to 0.793 vs. 0.682 to 0.726) (all P < 0.05). The mean cost per UDM/PD case identified was lower with NCDRS at score 25 (¥503.3($71.9)) and 27 (¥490.5 ($70.1)) than CFBG at 5.0, 5.1, 5.2, or 5.3 mmol/L (¥631.7 ($90.2), ¥611.8 ($87.4), ¥579.2 ($82.7) and ¥551.9 ($78.8)), whereas the mean costs per UDM case identified was higher with NCDRS at score 25 (¥1379.3 ($197.0)) and 27 (¥1315.1 ($187.9)) than CFBG at 5.3, 5.4, or 5.5 mmol/L (¥1301.7 ($186.0), ¥1247.7 ($178.2) and ¥1173.3 ($167.6)).

CONCLUSION

The NCDRS represents a valid and cost-effective tool for use in southwestern China to identify high-risk patients with UDM or PD who need a diagnostic test.

Imminent risk of COVID-19 in diabetes mellitus and undiagnosed diabetes mellitus patients

Diabetes mellitus is a non-infectious disease and has affected about 425 million adults globally and nearly 15.9 million of them reside in Africa. Moreover, the prevalence of undiagnosed diabetes mellitus is very high in Africa and approximates to around 62%. Nearly 75% of the total deaths due to diabetes are in individuals lesser than 60 years of age. The multifaceted disease of diabetes mellitus produces chronic complications such as, neuropathy, nephropathy, retinopathy, microangiopathy etc. These patients of diabetes mellitus are more susceptible to infections due to compromised immune system. Hence these patients of diabetes mellitus and undiagnosed diabetes mellitus are at greater risk of contracting COVID-19 infections. The dual impact of pathophysiology of COVID-19 infections in diabetes mellitus may increase morbidity and mortality in these patients. Hence there is need of health awareness in diabetics as well in the high-risk group for diabetes such as persons with hypertension and obesity. The scarcity of health resources, shortage of trained medical personnel and disease burden of infectious and non-infectious diseases has laid a heavy impact on the economy in Africa and this has been further strained due to the COVID-19 pandemic. The practice of preventive measures by the risk group of Undiagnosed Diabetes Mellitus patients will prevent them from getting infected by COVID-19 and at the same time decrease mortality rates and hence the undiscovered group that is the patients of undiagnosed diabetes mellitus needs to be vigilant regarding safe preventive practices.

Undiagnosed Diabetes Mellitus in Community-Acquired Pneumonia: A Prospective Cohort Study

Background

Diabetes mellitus is an important risk factor for community-acquired pneumonia, whereas the prevalence of undiagnosed diabetes mellitus and prediabetes in patients with community-acquired pneumonia is largely unknown. We aimed to determine the prevalence of prediabetes, undiagnosed diabetes mellitus, and risk factors associated with undiagnosed diabetes mellitus in a large European community-acquired pneumonia cohort.

Methods

This was a multicenter prospective cohort study of hospitals and private practices in Germany and Austria encompassing 1961 adults with community-acquired pneumonia included in the German Community-Acquired Pneumonia Competence Network (CAPNETZ) study between 2007 and 2014. The prevalence of undiagnosed diabetes mellitus and prediabetes was estimated based on hemoglobin A1c measurements. Logistic regression was used to assess risk factors for undiagnosed diabetes mellitus.

Results

Fifteen percent of patients had known diabetes mellitus. Among patients without known diabetes mellitus, 5.0% had undiagnosed diabetes mellitus and 37.5% had prediabetes. Male sex (odds ratio [OR], 2.45 [95% confidence interval {CI}, 1.35-4.45]), body mass index ≥25 kg/m2 (OR, 2.64 [95% CI, 1.48-4.72]), and hyperglycemia at admission (6-11 mM: OR, 2.93 [95% CI, 1.54-5.60] and ≥11 mM: OR, 44.76 [95% CI, 17.58-113.98]) were associated with undiagnosed diabetes mellitus. Patients with undiagnosed diabetes mellitus had a higher 180-day mortality rate compared to patients without diabetes mellitus (12.1% vs 3.8%, respectively; P = .001).

Conclusions

Undiagnosed diabetes mellitus was prevalent among community-acquired pneumonia. Male sex, overweight, and hyperglycemia at admission were associated with undiagnosed diabetes mellitus. The long-term mortality among patients with undiagnosed diabetes mellitus was high compared to patients without diabetes mellitus.

Periodontal abscess as a possible oral clinical sign in the diagnosis of undiagnosed diabetes mellitus of elderly in a dental clinic set up - a 7-year cross-sectional study

OBJECTIVE

To evaluate the periodontal abscess as a possible oral clinical diagnostic criteria for the diagnosis of diabetes mellitus in the elderly.

METHODS

In this clinical outpatient department, cross-sectional study of 84 months, 143 212 subjects between the ages of 40 and 84 years were screened for the presence of periodontal abscess. Relevant medical and dental histories were recorded using a questionnaire. The subjects who fulfilled the inclusion criteria of undiagnosed diabetes mellitus, presence of periodontal abscess, and absence of other systemic disease were referred for laboratory diagnosis of diabetes mellitus (HbA1c). The subjects tested positive for the diabetes were noted, statistical evaluation was undertaken to correlate between undiagnosed diabetes mellitus and periodontal abscess.

RESULTS

It was found out that 0.05% undiagnosed diabetes was noted among the 143 212 patients. Among the 143 212 subjects, 1352 met the inclusion criteria having periodontal abscess. Mean age of the participants was 57 ± 14.2 years. Among the 1352 subjects with periodontal abscess: 793 (58.65%) subjects had increased HbA1c (≥6.5% or 47.5 mmol/mol or 7.8 mmol/L); 559 (41.35%) individuals reported to have normal HbA1c (≤6.5% or 47.5 mmol/mol or 7.8 mmol/L). The difference was found to be statistically significant.

CONCLUSION

Periodontal abscess can be considered as possible oral clinical diagnostic criteria for the diagnosis of diabetes mellitus. Elderly individuals visiting dental clinics need to be given due attention to find out the possibility of having this systemic condition. Medical fraternities are advised to consider oral health parameters in the evaluation of the medical status of elderly individuals.
