Evaluation of the impact of abdominal obesity on glucose and lipid metabolism disorders in adults with Down syndrome.
A quick waist-to-height ratio flags insulin resistance in adults with Down syndrome long before other symptoms show.
01Research in Context
What this study did
Real de Asua et al. (2014) compared adults with Down syndrome to adults without it. They looked at waist-to-height ratio, blood sugar, and cholesterol. The goal was to see if a simple tape-measure test could flag insulin trouble.
What they found
Adults with Down syndrome had bigger waists and higher insulin resistance. Waist-to-height ratio spotted the problem as well as fancy lab tests. A ratio above 0.5 meant watch out.
How this fits with other research
McQuaid et al. (2024) seems to disagree. They found that extra weight in middle-aged adults with Down syndrome did not raise diabetes risk. The gap is age: Diego’s adults were younger, so the metabolic hit shows up earlier.
Esparza Ocampo et al. (2025) extend the warning to kids. Even normal-weight children with Down syndrome had worse lipid profiles. The message: start screening early, no matter the scale number.
Bertapelli et al. (2016) back this up. Their review shows exercise-only plans fail to cut weight in youth with Down syndrome. You need to pair movement with diet and medical checks.
Why it matters
You can add a 30-second waist-to-height check to any intake or re-assessment. If the ratio hits 0.5, refer for glucose and lipid labs. Catch problems before they turn into diabetes or heart disease.

03Original abstract
We aimed to describe anthropometric differences in weight-related disorders between adults with Down syndrome (DS) and healthy controls, as well as their disparate impact on glucose and lipid metabolism disorders. We underwent a cross-sectional study of 49 consecutively selected, community-residing adults with DS and 49 healthy controls in an outpatient clinic of a tertiary care hospital in Madrid, Spain. Siblings of adults with DS were studied as controls in 42 cases. Epidemiological data (age and gender), anthropometric data (body mass index, waist circumference, and waist-to-height ratio [WHR]), coexisting clinical conditions, and laboratory data (fasting glucose, insulin, glycated hemoglobin, creatinine, thyroid hormones, and lipid profile) were measured and compared between the groups. Adults with DS were significantly younger and more often male, with a higher prevalence of overweight and obesity than controls. Adults with DS also had a higher WHR, and more frequently presented abdominal obesity. Moreover, insulin resistance measured using the homeostatic model assessment was more prevalent among adults with DS and abdominal obesity. However, lipid profiles were similar between groups. The kappa correlation index for the diagnosis of abdominal obesity between waist circumference and WHR was 0.24 (95%CI: 0.13-0.34). We concluded that the prevalence of overweight, obesity, and abdominal obesity was higher in adults with DS than in controls. Adults with DS and abdominal obesity showed higher indexes of insulin resistance than their non-obese peers. WHR was a useful tool for the evaluation of abdominal obesity in this population.
