Prevalence of Hypertension in Prediabetic States Among Subjects with Obesity

Presenter: Ouassila, H. N. 

This multicenter, descriptive prospective study (2020–2024) included 332 prediabetic adults (mean age 48.6 ± 11.6 years; women, n=242) with obesity (n=50%) to assess hypertension prevalence and characteristics. 

Mean BMI was 30.2 ± 9.28 kg/m². Known hypertension was present in 62.4% of Obese subjects, while 47.5% had previously undiagnosed hypertension and ABPM newly identified hypertension in 44.6%. Overall confirmed hypertension reached 60.7% in obese vs 39.3% in non‑obese (p=0.016). Hypertension prevalence by prediabetes type was based on IFG 62.1%, IGT 56.2%, HbA1c 66.7%. Obesity was associated with higher hypertension phenotypes compared with non-obese subjects: systolic (59.5% vs 40.5%, p=0.048), diastolic (66% vs 34%, p=0.034), and combined hypertension (64.6% vs 35.4%, p=0.031). 

Hypertension is highly prevalent and often underdiagnosed in obese prediabetics, with higher burden and variability, highlighting the need for early detection and targeted management. 

Prevalence of Chronic Kidney Disease in Patients with Obesity: An Under-Recognised Comorbidity

Presenter: Lozano-Aida, C

Obesity increases risk of chronic kidney disease (CKD) via glomerular hyperfiltration, yet renal screening is often overlooked in obesity care. 

This retrospective cross-sectional study of 147 adults (mean age 48.6 years, BMI 43.6 kg/m²) attending a specialist clinic found CKD prevalence of 12.4%. Despite relatively low rates of diabetes and cardiovascular disease, many had severe obesity and additional cardiometabolic risk markers like lipoprotein (a) and fibrosis-4 index. Limited albuminuria testing suggests underdiagnosis. Findings highlight that CKD may be common even in young population with obesity and support integrating routine renal assessment into obesity management for earlier detection.

Inhospital Mortality and Complications Associated with Obesity in Patients Hospitalized in Internal Medicine in Spain: Findings from the RECALMIN-Ob Observational Study

Presenter: Gomez, J. C.

The RECALMIN-Ob study analysed the impact of obesity-related comorbidities on health outcomes, both overall and in chronic obstructive pulmonary disease (COPD), stroke, heart failure (HF) and pneumonia in discharged 559,728 people with obesity. This study used data from the NHS Minimum Basic Data Set. 

Cardiogenic shock and respiratory arrest were the strongest predictors, followed by sepsis and cancer. Stroke, HF and atrial fibrillation were obesity-related conditions linked to higher mortality. No obesity-related disease increased complication risk. Findings highlighted adverse impact of obesity on prognosis. 

Changes in Body Weight and Adiposity, and Their Associations with Cardiometabolic Risk Over 10 Years: The Kaunas Cardiovascular Risk Cohort Study

Presenter: Raskilienė, A.

The Kaunas Cardiovascular Risk Cohort Study evaluated the patterns of body weight and adiposity, and their link with cardiometabolic risk over 10 years in a Lithuanian adult population.

BMI increased in 76.1% of participants, with 31.5% shifting to a higher category, more often in women. Those with BMI increases had double the odds of developing arterial hypertension (OR 2.02) vs. those with stable/reduced BMI. Waist circumference increase correlated with higher triglycerides (p<0.001), total cholesterol (p=0.002), and fasting glucose (p=0.033), while inversely correlated to HDL cholesterol (p<0.001). Overall, long-term increases in body weight and central adiposity showed associations with lipid abnormalities.
