People with larger waist sizes tend to have higher blood pressure, cholesterol, triglycerides, and blood sugar levels even when their body mass index is the same, and the same is true for people with higher body mass index when their waist size is considered.
Scientific Claim
Higher waist circumference tertiles are associated with higher blood pressure, cholesterol, triacylglycerol, and glucose concentrations within each body mass index tertile, and higher body mass index tertiles are associated with higher levels of these factors within each waist circumference tertile.
Original Statement
“Higher WC tertiles were associated with higher blood pressure and higher cholesterol, triacylglycerol, and glucose concentrations within each tertile of BMI and vice versa.”
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
Based on abstract only - full methodology not available to verify. The study is observational, so causal claims are not supported, but association claims are appropriate.
