High body mass index and triglyceride levels at health checkups increase the risk of new-onset chronic kidney disease and worsening renal function: the TAMA MED Project-CKD.

Background: Health checkups are important in patients with chronic kidney disease (CKD), which is not easily accompanied by subjective symptoms. CKD can be caused or aggravated by factors that have not yet been identified.

Methods: This retrospective cohort study included 7 483 patients who underwent specific annual health checkups at a medical institution in Tama City, did not have CKD in 2012, and continued to undergo checkups (aged 40-74 years).

Sarcopenia and coexistent risk factors detected using the 'Yubi-wakka' (finger-ring) test in adults aged over 65 years in the public annual health check-up in Tama City, Tokyo: a cross-sectional study.

Objectives: To examine the positive rate of sarcopenia using the 'Yubi-wakka' (finger-ring) test and associated risk factors among adults aged 65 years and older.

Design: Cross-sectional study.

Setting: We used the Yubi-wakka test, which has been developed and validated as a predictor of sarcopenia, frailty, disability and mortality.

Anemia and atrial fibrillation as independent risk factors for new-onset chronic kidney disease: the TAMA-MED Project-CKD and AF.

Background: Various risk factors have been identified for the new onset or rapid deterioration of chronic kidney disease (CKD). However, it is thought that many risk factors that have not yet been clarified remain.

Methods: Based on the results of specific annual health checkups at Tama City ( = 18 383) in 2017 and 2018, we analyzed the factors that cause new-onset CKD and the risk factors that rapidly worsen renal function.

Impact of Chronic Kidney Disease Classification on New-Onset Atrial Fibrillation in the General Population - The TAMA MED Project-AF and CKD.

Background: Atrial fibrillation (AF) and chronic kidney disease (CKD) are known risk factors for each other. In Tama City in Tokyo, 12-lead ECG and serum creatinine concentration have been included as essential examinations in specific health checkups to diagnose AF and CKD. In the present study, we investigated the impact of CKD classification on new-onset AF in the general population.

Medical and Dental Visits of Chronic Kidney Disease-Diagnosed Participants Analyzed From the Specific Health Checkups Results in Japan: TAMA MED Project-CKD.

Background: Since 2012, Tama City has promoted the early detection of chronic kidney disease (CKD), through an initiative that measures serum creatinine as part of the specific health checkups. We examined preventive measures against CKD deterioration based on the outcomes of this initiative.

Methods: The complications, medication status, body mass index, smoking status and other determining factors were surveyed among CKD-diagnosed participants over 3 years between 2013 and 2015.

"Yubi-wakka" (Finger-Ring) Test: A Tool to Detect Prefrailty in Elderly Populations, a Pilot Study.

Background: Preventing frailty of elderly is an urgent issue in Japan. The "Yubi-wakka" (finger-ring) test was developed and validated as a predictor of sarcopenia, disability and even mortality. To clarify the prevalence of "frailty" defined by this test and the relationship between other indexes cross-sectionally and prospectively, we conducted this study.

Prevalence and Incidence of Atrial Fibrillation in the General Population Based on National Health Insurance Special Health Checkups - TAMA MED Project-AF.

Background: Although National Health Insurance special health checkups have been useful for the diagnosis of metabolic syndrome, they are insufficient to identify atrial fibrillation (AF). In Tama City in Tokyo, 12-lead electrocardiogram has been included as an essential examination in special health checkups to diagnose AF since 2008.

Methods and results: In subjects aged 40-74 years at entry, prevalence of AF was 0.
