Is Iran’s diabetes cascade improving over time?
Open access · cc by · source: Europe PMC
From 2004–2016 prevalence rose 8.4%→13.2% and awareness 53.5%→82.2%, but treatment (~36–46%) and control (~15–21%) stayed suboptimal.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
National STEPS data can show rising awareness while control stays low.
Iranian STEPS analyses found diabetes prevalence and awareness climbing, treatment peaking then dipping, and glycemic control remaining low—illustrating cascade leakage after detection.
Evidence for the claim as stated.
Many countries run T2DM detection/adherence programs, but authors still judge them insufficient for rising burden.
A review of ongoing T2DM care activities highlights detection, monitoring, and adherence efforts amid obesity/urbanization drivers and HIV/TB co-morbidity, while arguing current efforts under-match need.
Scope note — one-country cascade metrics ≠ proof any listed program closed control gaps
Limits the claim's scope: a different population, assay, or outcome.
Smartphone self-management tools are one narrow cascade lever, not a system fix.
A smartphone diabetes self-management application study for adults with type 1 diabetes tests digital support for day-to-day management rather than national awareness/treatment/control rates.
Scope note — app trial ≠ population effective coverage
Limits the claim's scope: a different population, assay, or outcome.
Awareness up, control still low in national survey vs Many programs exist but judged insufficient vs App-level self-management support in T1D

Is Iran’s diabetes cascade improving over time?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Prevalence 8.4, 9, 11.1, 13.2% across rounds.
The prevalence of diabetes in four rounds was 8.4, 9, 11.1 and 13.2%, respectively
Awareness rose to 82.2%; treatment 39.6% in last round.
53.5, 65.6, 70.5 and 82.2% were aware of their condition and 35.9, 42, 46 and 39.6% were treated for this condition, respectively
Key findings
Prevalence and awareness climbed; treatment peaked then dipped; control remained low. Female sex, age>40, urban residence, mid wealth, and insurance associated with prevalence.
Methodology
Analyzed four STEPS NCD surveys with descriptive stats and logistic regression for sociodemographic correlates of awareness/treatment/control.
Limitations
Does not evaluate a specific intervention trial; age/sex unadjusted prevalence trends as reported.
