“…Physical performance measures did not differ significantly between low and medium BMI groups for either sex. Many previous studies have found that higher BMI is associated with poor performance [13,14,16,17,19,[23][24][25], and our present study results were consistent with these findings.…”

“…Marsh et al [23] reported an association between low HGS and an increased risk of developing major mobility disability, as well as a U-shape relationship between baseline BMI and the risk of developing major mobility disability. Akune et al [24] reported that both underweight and obese individuals were at an increased risk for need of care and decreased muscle strength and physical ability. The association between BMI and frailty also shows a U-shaped relationship, in which the level of frailty in elderly individuals increases among those with low and high BMIs [25].…”

“…Hand grip strength is also used in elderly adults as a screening index for sarcopenia, which is defined as a decline in skeletal muscle mass and muscle function [1,2]. Furthermore, poor hand grip strength is associated with mortality [3,4] and disability [4,5] in older adults and has been found to be a useful index for frailty [6,7]. Reports have also emerged in recent years demonstrating a relationship between hand grip strength and oxidative DNA damage, which has been found to be related to cancer, heart disease, and diabetes [8].…”

Objectives Reference values for hand grip strength in Japanese community-dwelling elderly independent in activities of daily living (ADLs) were calculated by metaanalysis. Methods Papers reporting data on hand grip strength in elderly Japanese adults C60 years of age and independent in ADLs were retrieved from electronic databases. Data were extracted from the selected papers and the weighted mean for hand grip strength by sex was calculated by random effect model. The association of hand grip strength with age and body weight was also analyzed using metaregression analysis. Results Data for 15,784 individuals (5216 men and 10,568 women; mean age 67.0-79.8 years) were extracted from 97 sets of data from 33 papers. The weighted mean for hand grip strength was calculated as 33.11 kg in women. A significant negative correlation was also seen between hand grip strength and age.Conclusions The mean hand grip strength of elderly people calculated in this study can be used as a reference value for the hand grip strength of Japanese communitydwelling elderly who are independent in ADLs. However, age needs to be considered in reference values for hand grip strength.

ObjectivesReadmission is a common and serious problem associated with heart failure (HF). Unfortunately, conventional risk models have limited predictive value for predicting readmission. The recipients of long-term care insurance (LTCI) are frail and have mental and physical impairments. We hypothesised that adjustment of the conventional risk score with an LTCI certificate enables a more accurate appreciation of readmission for HF.MethodsWe investigated 452 patients with HF who were followed up for 1 year to determine all-cause readmission. We obtained their clinical and socioeconomic data, including LTCI. The three clinical risk scores used in our evaluation were Keenan (2008), Krumholz (2000) and Charlson (1994). We used net reclassification improvement (NRI) to assess the incremental benefit.ResultsPatients with LTCI were significantly older, and had a higher prevalence of cerebrovascular disease and dementia than those without LTCI. One-year all-cause readmission (n=193, 43%) was significantly associated with all risk scores, receiving LTCI and the category of LTCI. Receiving LTCI was associated with readmission independent of all risk scores (HR, 1.59 to 1.63; all p<0.01). Adding LTCI to all risk scores led to a significantly improved reclassification, which was observed in the subgroup of patients with HF with preserved ejection fraction (≥50%) but not in the subgroup with reduced ejection fraction (<50%).ConclusionsPossession of an LTCI certificate was independently associated with 1-year all-cause readmission after adjusting for validated clinical risk scores in patients with HF. Adding LTCI status significantly improved the model performance for readmission risk, particularly in patients with HF and preserved ejection fraction.
