Is Iran’s diabetes cascade improving over time?
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.

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
What they did
Analyzed four STEPS NCD surveys with descriptive stats and logistic regression for sociodemographic correlates of awareness/treatment/control.
What they found
Prevalence and awareness climbed; treatment peaked then dipped; control remained low. Female sex, age>40, urban residence, mid wealth, and insurance associated with prevalence.
The limits
What it doesn't show
Does not evaluate a specific intervention trial; age/sex unadjusted prevalence trends as reported.
