Chronic kidney disease (CKD) is a global health concern and a major long-term complication of diabetes, yet its burden remains understudied in regions with limited epidemiological data. This study aimed to evaluate the prevalence of CKD and its associated risk factors in the Iranian adult population, stratified by diabetes status.

Population-based cross-sectional study.

Nationally representative survey across Iran (STEPS 2021).

17 607 adults aged ≥25 years with complete kidney function and albuminuria data, selected through systematic sampling with weighting to ensure national representativeness.

CKD was defined as an estimated glomerular filtration rate (eGFR)

The national prevalence of CKD was 11.9% (95% CI 11.2% to 12.6%), with 9.1% (8.5% to 9.9%) among individuals without diabetes and 28.6% (26.2% to 31.1%) among those with diabetes. According to KDIGO classification, 88.1% (87.4% to 88.8%) were at low risk, 9.0% (8.4% to 9.6%) at moderate risk, 2.0% (1.6% to 2.4%) at high risk and 0.9% (0.7% to 1.1%) at very high risk. Albuminuria was more prevalent than low eGFR in both groups with (22.5% (20.4% to 24.8%) vs 10.3% (8.7% to 12.1%)) and without (5.7% (5.2% to 6.3%) vs 4.3% (3.8% to 4.8%)) diabetes. Diabetes was more strongly linked to albuminuria than low eGFR and was progressively associated with higher risk categories (adjusted ORs (aORs) 2.41 (2.03–2.86) for moderate, 2.63 (1.74–3.97) for high, 3.93 (2.56–6.07) for very high vs low-risk). CKD prevalence was highest in northwest Iran, increased significantly with age, with a stronger association observed for low eGFR than albuminuria, and was associated with hypertension (aOR 2.41 (2.07–2.82)), dyslipidaemia (1.60 (1.31–1.94)), obesity (1.94 (1.59–2.36)), ischaemic heart disease (1.53 (1.25–1.87)) and physical inactivity (1.40 (1.20–1.62)). Higher socioeconomic status and education were associated with lower odds of CKD.

CKD is a major burden, especially in individuals with diabetes, with regional and socioeconomic disparities. Addressing risk factors, integrating CKD into non-communicable disease surveillance and prioritising it in global health agendas, including the Sustainable Development Goals, are essential.

To examine demographic, behavioural and clinical determinants of self-rated health (SRH) among Iranian adults with hypertension (HTN), with a particular focus on the association between blood pressure (BP) control and perceived health.

National cross-sectional analysis of 15 predictors spanning demographic, lifestyle and clinical domains.

2021 Iranian STEPwise Approach to Non-communicable Disease Risk Factor Surveillance, a nationally representative survey.

A total of 8812 adults with HTN (mean age 56.97 years; 57% female). Controlled HTN was defined as systolic blood pressure

The primary outcome was SRH, measured on a standard EuroQol-Visual Analogue Scale (0–100).

Controlled HTN was independently associated with higher SRH scores (β=1.31, 95% CI 0.07 to 2.54). Positive predictors of SRH included male gender (β=4.34, 95% CI 3.38 to 5.31), higher wealth (richest vs poorest: β=5.52, 95% CI 4.06 to 6.97), sufficient physical activity (β=4.38, 95% CI 3.48 to 5.28), healthier diet (β=3.06, 95% CI 1.99 to 4.14) and complementary insurance coverage (β=2.50, 95% CI 0.63 to 4.37). Significant negative predictors included diabetes mellitus (β=–4.23, 95% CI –5.59 to –3.26), dyslipidaemia (β=–3.61, 95% CI –4.62 to –2.59), people who smoke (β=–4.21, 95% CI –5.64 to –2.78) and older age. Notably, antihypertensive medication use showed one of the strongest negative associations with SRH (monotherapy: β=–4.83; combination therapy: β=–5.28), likely reflecting underlying disease severity and treatment burden.

Better SRH among hypertensive adults was associated with controlled BP, healthier lifestyle patterns and higher socioeconomic status. Conversely, comorbidities, smoking, older age and antihypertensive treatment were linked to poorer perceived health. Integrating SRH screening into HTN management may help identify vulnerable individuals and inform targeted interventions addressing behavioural and socioeconomic determinants of health.

The efficacy and safety of SMS text message-delivered interventions for providing pain self-management education and improving clinical pain outcomes have been demonstrated in several randomised controlled trials. However, little is known about the feasibility and effectiveness of these interventions within Australian hospital settings. The current protocol describes a trial designed to evaluate the effectiveness and implementation of an SMS text message-delivered intervention designed to support patients’ engagement with pain self-management strategies and improve clinical pain outcomes after total knee replacement surgery.

A hybrid, type 1 effectiveness-implementation trial will be conducted at a private hospital in Australia. Participants (n=130) will be randomised to either the intervention group (receiving a pain self-management educational video prior to surgery, plus daily SMS text message reminders for 3 weeks after surgery) or an active control group (receiving the pre-surgery video alone, without text message reminders) in addition to usual care. Effectiveness outcomes will be pain intensity (primary), opioid dose, knee function and pain-related distress and will be recorded at baseline, 3 days, 3 weeks, 6 weeks, 3 months and 6 months after surgery using self-reported surveys. Pain self-efficacy and health-related quality of life will be measured at 6 weeks, 3 months and 6 months post-surgery. Implementation outcomes (Reach, Experience, Adoption, Implementation, Maintenance) will be evaluated using mixed (qualitative and quantitative) methods. This trial represents a first step towards the translation of digitally delivered postoperative support for engaging with pain self-management in the Australian healthcare system.

The study protocol was reviewed and approved by the Austin Health Human Ethics Research Committee (Australia, HREC/110142/Austin-2024). Study results will be published in a peer-reviewed journal and presented at scientific and professional meetings.
