To examine chronic kidney disease (CKD) prevalence, incidence, prognosis, kidney function decline and associated risk factors among people with diabetes and/or hypertension.

Cross-sectional multicentre study.

14 primary care centres across Jakarta.

Adults (≥18 years) with diabetes and/or hypertension were included. Exclusion criteria were receiving kidney replacement therapy, language barrier, cognitive impairments, refusal to consent and pregnancy. Participants were grouped into three categories: hypertension only, diabetes only and both.

None.

Primary outcomes included CKD prevalence, incidence, number-needed-to-screen, KDIGO-based prognosis and annual kidney function decline. Secondary outcomes were risk factors for CKD, uncontrolled blood glucose, blood pressure and albuminuria.

A total of 1263 participants were enrolled: 51% had hypertension, 17.6% diabetes and 31.4% both. Mean age: 57.1±10.2 years, 72.2% female and 76% obese. Renin angiotensin aldosterone system inhibitors were prescribed in 32.3%, and only 1.2% used insulin despite a median glycated haemoglobin of 7.5% (IQR: 6.5–9.1). CKD prevalence was 14.8%, with an incidence rate of 9.1 per 100 person-years; number-needed-to-screen was 7. Based on KDIGO criteria, 48.9% were at moderate-to-very high risk of adverse outcomes. Baseline estimated glomerular filtration rate was 80.9 (SE=10.1), declining by 4.7 (SE=9.9) mL/min/1.73 m² annually. CKD incidence was higher with albuminuria (OR 3.6, p=0.007) in the combined group; older age (OR 4.5, p

CKD burden is high among people with diabetes and hypertension. Nearly half were at elevated risk despite preserved kidney function, highlighting the need for targeted early screening.

Despite the abundant evidence showing the benefits of muscle-strengthening exercise (MSE), no epidemiological tool is available for assessing MSE among Indonesian university students. This study is the first to adapt the Muscle-Strengthening Exercise Questionnaire (MSEQ) from its original English version into another language, specifically Indonesian, incorporating cultural adaptations and to pilot test it to assess its validity and reliability among university students in Indonesia.

Translation and cultural adaptation, content validity studies, concurrent validity studies and reliability studies were conducted following COnsensus-based Standards for the Selection of Health Status Measurement INstruments guidelines. Content validation, conducted with three experts and nine university students, informed the development of the MSEQ Indonesian version. The concurrent validity study compared the results of measuring MSE frequency, intensity, duration and volume with those of the 7-day diary and relative handgrip strength with 22 respondents for concurrent validity against subjective measurement and 70 respondents for concurrent validity against objective measurement. For the reliability study, 39 respondents were asked to fill the MSEQ Indonesian version twice with a time interval of 7 days.

The study involved 143 participants, including experts and university students from three universities across two different islands in Indonesia.

Single administration MSEQ, consecutive administration MSEQ and 7-day diary recording resulted in 0%, 33.8% and 68.5% dropout rate, respectively. Moderate-to-strong correlations were observed between the results for the weekly frequency, duration, intensity and volume of MSE and those of the 7-day diary and hand grip strength. Test–retest reliabilities were good to excellent for machine weight, holistic and overall MSE but poor for bodyweight MSE. In assessing the target muscle group, the MSEQ Indonesian version showed good test–retest reliability for machine-weight MSE but poor-to-very good test–retest reliability for bodyweight, free weight and holistic MSE.

Our study demonstrated the acceptable validity and reliability of the Indonesian version of the MSEQ for assessing MSE among university students in Indonesia, not only by comparing each dimension of MSE with subjective measures but also by comparing MSE volume with objective measures. To enhance the generalisability of these findings, future studies should assess the MSEQ Indonesian version in diverse adult populations by considering dropout rates found by our study, ensuring its broader applicability and sample size adequacy.
