This cross-sectional study assessed the frequency of vascular complications among newly detected type 2 diabetes mellitus patients presenting to the Department of Endocrinology at BIRDEM General Hospital, Dhaka, Bangladesh. The study period was January to December 2019. All participants were screened using the study's inclusion and exclusion criteria and provided written informed consent before enrollment.
A total of 311 newly diagnosed patients were included. The cohort's mean age was 53.28 ± 8.84 years, with 63.7% male and 36.3% female participants. The abstract provides these baseline demographic descriptors but does not report additional enrollment details, randomization, or longitudinal follow-up beyond the cross-sectional assessment.
Among the 311 respondents, 164 patients (52.7%) had at least one vascular complication at the time of diagnosis, while 147 patients (47.3%) had no recorded complications. The study separated complications into microvascular and macrovascular categories and also reported the proportion with both types concurrently.
Considering the entire cohort (n=311), 40.2% of patients had one or more microvascular complications. The individual microvascular complication frequencies reported in the abstract were:
Neuropathy was identified as the predominant microvascular complication in this newly detected patient population.
Macrovascular complications were present in a smaller proportion of patients: 7.7% had macrovascular complications and 4.8% had both micro- and macrovascular complications. Specific macrovascular frequencies reported were:
The abstract highlights coronary artery disease as the most common macrovascular complication among newly diagnosed patients in this cohort.
The study recorded several prevalent risk factors within the cohort. Reported prevalences included:
These variables were examined for statistical association with the various vascular complications; specifics of measurement definitions (for example, BMI cutoffs for overweight/obesity) are not detailed in the abstract.
The abstract reports statistically significant associations between selected risk factors and individual complications. Reported associations included:
Neuropathy: significantly associated with hypertension, fasting plasma glucose, HbA1c, total cholesterol and LDL.
Retinopathy: significantly associated with hypertension, fasting plasma glucose, HbA1c, LDL and urine albumin-to-creatinine ratio (ACR).
Nephropathy: significantly associated with hypertension, HbA1c, total cholesterol, LDL and urine ACR.
Cardiovascular disease (CVD): significantly associated with smoking, hypertension, fasting plasma glucose, 2-hour plasma glucose after OGTT, HbA1c, total cholesterol and LDL.
The abstract does not present the specific statistical tests, effect sizes, confidence intervals, p-values, or adjustment strategies used in these analyses. The direction of association implied is that higher values or presence of these risk factors correlated with higher frequency of the stated complications at diagnosis, but precise quantitative relationships are not provided in the abstract.
In this cross-sectional sample of newly detected type 2 diabetes mellitus patients, more than half had at least one vascular complication at diagnosis. Microvascular complications were substantially represented (40.2%), with neuropathy the most common microvascular finding. Macrovascular complications were less frequent but present (7.7%), with coronary artery disease the most common macrovascular diagnosis. Common cardiometabolic and behavioral risk factors—hypertension, dysglycemia measured by fasting plasma glucose and HbA1c, dyslipidemia (total cholesterol and LDL), smoking and elevated urine ACR—were significantly associated with specific complications.
These findings emphasize that a substantial proportion of patients may already have established vascular complications at the time of type 2 diabetes diagnosis. Early screening for microvascular and macrovascular complications and identification of modifiable risk factors (blood pressure, glycemic control, lipids, smoking, and albuminuria) are suggested clinical priorities based on the presented frequencies and associations.
