Article Synopsis
  • - The study examined the relationship between trunk-to-peripheral fat ratio, measured by dual-energy absorptiometry (DXA), and kidney function (estimated glomerular filtration rate or eGFR) in elderly Japanese men aged 65 and older.
  • - Results showed that higher trunk-to-peripheral fat ratios were linked to lower eGFR values, indicating worse kidney function, even after controlling for overall body fat and other factors.
  • - The findings suggest that central obesity, specifically a larger trunk fat distribution, negatively affects kidney function in older males, separate from overall body fat levels.

Background: Several studies have examined the association between physical performance and fracture in women, but few such studies have targeted elderly men. This study aimed to determine whether the combined results of several physical performance tests can predict the subsequent incidence of fractures in elderly men after adjusting for confounding factors.

Methods: Of the 2174 elderly men who participated in this study, 2012 completed the baseline study visit, including physical performance tests (walking speed, hand grip strength, and one-leg standing) and measurement of bone mineral density by dual-energy X-ray absorptiometry.

Unlabelled: Areal BMD (aBMD) from DXA is not a sufficiently accurate predictor of fracture. Novel volumetric BMD derived from 3D modeling of the hip from DXA images significantly improved the predictive ability for hip fracture relative to aBMD at the femoral neck, but not aBMD at the total hip.

Introduction: To clarify whether volumetric and geometric indices derived from novel three-dimensional (3D) modeling of the hip using dual-energy X-ray absorptiometric (DXA) images improve hip fracture prediction relative to areal bone mineral density (aBMD).

Background: Body mass-independent parameters might be more appropriate for assessing cardiometabolic abnormalities than weight-dependent indices in Asians who have relatively high visceral adiposity but low body fat. Dual-energy X-ray absorptiometry (DXA)-measured trunk-to-peripheral fat ratio is one such body mass-independent index. However, there are no reports on relationships between DXA-measured regional fat ratio and cardiometabolic risk factors targeting elderly Asian men.

Introduction: Cross-sectional studies have shown that patients with type 2 diabetes mellitus (T2DM) have low circulating levels of osteocalcin (OC) and undercarboxylated OC (ucOC). This longitudinal study aimed to examine whether low OC or ucOC levels at baseline are associated with the risk of incident T2DM.

Methods: We examined 1700 community-dwelling Japanese men (≥65 years) after excluding those with history of diseases (other than T2DM) or medications that affect bone and glucose metabolism.

More than half of women are reported to be overweight or obese in Mongolia, thus becoming a big health issue. Though maternal obesity is a known risk factor for cesarean section (CS), it remains unclear how much a high maternal body mass index (BMI) would influence the risk of CS among pregnant women in Mongolia. This study aimed to investigate whether a higher maternal BMI is related to CS delivery in Darkhan-Uul Province, Mongolia.

Purpose: Many studies have reported that patients with a history of gastrectomy (gastrectomized patients) have lower areal bone mineral density (aBMD) and higher fracture risk than those without. However, population-based studies on this topic are scarce, and little is known regarding the bone metabolic status of gastrectomized patients in the long-term. This study aimed to clarify the association of gastrectomy with aBMD, bone metabolism markers, and fracture risk in community-dwelling elderly Japanese men.

Unlabelled: Frail elderly individuals have elevated risks of both fracture and mortality. We found that incident fractures were associated with an increased risk of death even after adjusting for pre-fracture frailty status as represented by physical performance tests and laboratory tests for common geriatric diseases in community-dwelling elderly Japanese men.

Introduction: While fractures reportedly increase the risk of mortality, frailty may complicate this association, generating a false-positive result.
