Abstract
OBJECTIVES This study aimed to examine the relationship between anemia and all-cause mortality in Chinese centenarians. DESIGN Prospective cohort study. SETTING AND PARTICIPANTS We included 1002 Chinese centenarians from the China Hainan Centenarian Cohort Study (CHCCS) MEASUREMENTS: Standard procedures were followed to perform blood analysis, home interviews, and physical examinations. Anemia was defined as a hemoglobin level of less than 130 g/L for men and less than 120 g/L for women. RESULTS During the 9-year follow-up period, a total of 929 (92.7%) deaths were identified. Cox proportional hazards regression models revealed that anemia (hazard ratio [HR] 1.289, 95% confidence interval [CI]: 1.117-1.489) was significantly associated with all-cause mortality. There was an apparent dose-response relationship between anemia and all-cause mortality. Centenarians with severe anemia had approximately 1.6 times higher likelihood of all-cause mortality than those without anemia (HR 1.662; 95% CI: 1.154-2.394). CONCLUSION Anemia is associated with an increased risk of all-cause mortality in Chinese centenarians. Further research will be needed to collect more comprehensive data on the etiology of anemia and causes of death in centenarians.

Abstract
OBJECTIVE Assessment of the association between anemia and recovery of physical disability in patients with functional impairment. DESIGN A retrospective cohort study. SETTING A convalescent rehabilitation ward. PARTICIPANTS The subjects were patients undergoing convalescent rehabilitation due to neurologic disease, musculoskeletal disorders, or hospital-associated deconditioning. Patients were classified into 3 groups (no anemia; mild anemia [men: hemoglobin of 11.0-12.9 g/dL; women: hemoglobin of 11.0-11.9 g/dL]; and moderate/severe anemia [hemoglobin < 11.0 g/dL]) based on hemoglobin levels. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The study outcomes were functional independence measures for motor function (FIM-M) score at discharge, changes in the FIM-M score between hospital admission and discharge, length of stay, and FIM-M efficiency score (change in FIM-M score divided by length of stay). A linear regression model was constructed to explore the association of anemia with the FIM-M efficiency score. As a subgroup analysis, we constructed a linear regression model to explore the association of anemia with the FIM-M efficiency score in patients with or without stroke. RESULTS Of 376 consecutive patients with a mean age of 80 years, 258 (69%) had mild or moderate/severe anemia. There were no significant differences between the 3 groups in the FIM-M score at discharge, changes in the FIM-M score, length of stay, and FIM-M efficiency score. A multiple linear regression model showed that the FIM-M efficiency score was not associated with anemia (mild anemia group: β=-0.02, P=.8; moderate/severe anemia group: β=-0.005, P=.9). In the subgroup analysis of patients with or without stroke, the multiple regression model also showed no significant association between anemia and FIM-M efficiency score in each group. CONCLUSIONS Anemia on admission was common among patients in a convalescent rehabilitation ward but was not associated with improvement of FIM-M after rehabilitation.

Abstract
Anemia is common in older people and is associated with low hand grip strength (HGS). However, there is no study of the association of anemia with both absolute and various relative HGS indices. Therefore, the objectives of this study are to examine the association of anemia with absolute and relative HGS indices and to evaluate whether the relative HGS indices are useful as risk indices of anemia. In this large-scale cross-sectional study, we analyzed the association of anemia with anthropometric indices, absolute HGS indices, and relative HGS indices using both crude and adjusted binary logistic regression models. A total of 24,022 participants were included in the final analysis. Anemia was defined as a blood hemoglobin concentration of less than 13.0 g/dL for men, less than 11.0 g/dL for pregnant women, and less than 12.0 g/dL for nonpregnant women. We considered covariates such as residential area, marital status, education level, occupation, household income, alcohol consumption, smoking status, muscular exercise, walking exercise, blood pressure, and age for men, while for women, we also included menopause. The mean ages of the subjects in this study were 51.89 ± 0.19 years in the nonanemic group and 66.56 ± 0.61 in the anemic group in men and 52.55 ± 0.19 in the nonanemic group and 51.85 ± 0.44 in the anemic group in women. The number of anemic patients was 570 (5.5%) in men and 1638 (12%) in women. The mean HGS value in the dominant hand was 38.97 ± 0.11 in the nonanemic group and 30.84 ± 0.38 in the anemic group in men and 22.64 ± 0.07 in the nonanemic group and 21.85 ± 0.16 in the anemic group in women. Age was highly associated with anemia in men but not in women. Absolute HGS indices, such as the dominant HGS index and both HGS indices, were negatively associated with anemia in both sexes in all crude and adjusted models. All relative HGS indices were associated with anemia in men, but in women, only dominant HGS divided by height and both HGS divided by height were related to anemia status in all models. The associations between anemia and absolute and relative HGS indices were significantly high in men, while in women, these associations were of moderate strength. Anemia was negatively associated with HGS in the Korean population. The strengths of the associations of anemia with the absolute and relative HGS indices showing the highest association with anemia were similar. Therefore, there is no need to use relative HGS indices as risk factors for anemia, and absolute HGS indices, as easily obtained and cost-effective measurement, are suitable.

Tal S. Mortality in the Oldest-Old Adults After Discharge From Acute Geriatric Ward. Gerontol Geriatr Med 2023; 9:23337214231156300. [PMID: 37250599 PMCID: PMC10214041 DOI: 10.1177/23337214231156300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 01/18/2023] [Accepted: 01/21/2023] [Indexed: 05/31/2023] Open
Abstract
Aim: To examine risk factors for post-discharge mortality in the oldest-old patients. Methods: We have assessed the risk factors for mortality after discharge from acute geriatric ward in 448 patients aged ≥90. Results: Low albumin, high urea, and full dependence were risk factors for mortality within 1 month and within 1 year after discharge from hospital. Age-adjusted Charlson Comorbidity Index score, neuroleptic drug treatments and frailty were specific risk factors for post-discharge mortality within 1 year. By Cox regression analysis, the risk factors associated with higher hazard ratios for post-discharge mortality within 14 years follow-up were age-adjusted Charlson Comorbidity Index score, poor functional status, anemia and dementia as comorbidities, neuroleptic drug treatments, low albumin, high urea, and high vitamin B12. Conclusion: Optimal treatment of the condition due to which the patient has been hospitalized and of the medical complications that occurred during hospitalization, while preventing functional decline, might secure longer post-discharge survival.

Relationship between Selected Functional Performance Parameters and the Occurrence of Anaemia in Hospitalized Females and Males Aged 80 and More. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13179.

Abstract
Anaemia is considered a factor that significantly increases the risk of disability and mortality in the elderly. Among the hospitalized elderly, the incidence of anaemia is higher than in the general population, which necessitates extensive diagnostics for anaemia in this group. The aim was to assess the relationship between the occurrence of anaemia in hospitalized females and males, aged 80 years and more, and selected determinants of motor fitness. The analysis covered 91 females and 57 males aged 80 and more. The study implemented haemoglobin level, handgrip strength, a lower limb strength, mobility and balance measurement. The analysis used the logistic regression model and the cut-off point was determined by ROC curve. A 1 kg increase in muscle strength reduced the risk of anaemia in a group of males by 12%. The value of handgrip strength from which anaemia can be predicted in a group of males is 24.4 kg. In the female group, no statistically significant correlations were found. There is a need to continue research in this area with the participation of a larger group of respondents to look for potential factors that may be related to anaemia, in order to find non-invasive diagnostic tools useful for elderly people.

Abstract
Introduction: Anemia is a common blood disorder in the elderly which is associated with numerous poor medical outcomes. However, there is currently no study that assesses anemia prevalence of the Indonesian elderly population aged ≥60 years old in multiple provinces and analyzes its association with handgrip muscle strength using a large sample size. Aim: We aimed to elucidate the prevalence of anemia and analyze factors associated with handgrip strength in elderly. Method: This was a cross-sectional study using data from the Indonesian Family Life Survey-5 (IFLS-5). All participants aged ≥60 years old were included in this study. Exclusion criteria were: (1) respondents who refused to take health measurements (hemoglobin (Hb) level, handgrip strength, weight, stature, and waist circumference); (2) respondents with incomplete or missing data; (3) respondents with history of stroke; and (4) respondents with history of pain, swelling, inflammation, injury, and surgery on one or both hands within the last 6 months. The dependent variable for this study was handgrip strength. Subjects were classified as weak if the handgrip strength was <28 kg for men and <18 kg for women based on classification from the Asian Working Group for Sarcopenia (AWGS) 2019. The independent variables were Hb level, gender, age, body mass index (BMI), waist circumference, smoking history, comorbidities, and current use of drug therapies. Based on WHO standard, male and female participants with Hb less than 13 g/dL and 12 g/dL, respectively, are defined as anemic. Statistical analyses used included correlation, bivariate logistic regression, and multivariate logistic regression. Result: A total of 3192 individuals were selected for analysis. Overall, 38.8% of participants had anemia, and the prevalence of anemia increases with age. A total of 56.30% of participants aged ≥80 years had anemia. There was a positive correlation between Hb level and handgrip strength in the Indonesian elderly population (r: 0.349; p value: <0.001). Multivariate analysis showed that anemia was significantly associated with weak handgrip strength (OR: 1.557; 95% CI: 1.314-1.846; p value: <0.001). Age ≥ 80 years (OR: 5.234), age 70-79 years (OR: 3.152), low BMI (OR: 1.827), and hypertension (OR: 1.340) were associated with weak handgrip strength in multivariate analysis. Conclusion: The prevalence of anemia in the Indonesian elderly was 38.8% and anemia was associated with weak handgrip strength. The association of anemia with weak handgrip strength is more pronounced in males and the elderly aged ≥80 years.

Abstract
Introduction Haemoglobin concentrations decrease with age. Abnormally low and high haemoglobin concentrations are associated with reduced cognition; however, the evidence for these associations in cohort data is limited. This study aims to assess the relationship between haemoglobin concentration and cognition in a well-characterised cohort of older adults. Methods Two hundred and fifty-two healthy participants were drawn from the Aberdeen Children of the 1950s cohort, aged between 59 to 65 years. Participants underwent cognitive tests of processing speed, memory, verbal and nonverbal reasoning, and language ability and these were used to construct a global cognitive score, g, using principal component analysis. Haemoglobin concentration in the blood was measured concurrently. Hierarchical multiple regression models were constructed assessing the relationship between haemoglobin concentration and each cognitive measure and these were corrected for age, sex, education, C-reactive protein, hypertension, and body mass index. Results Significant linear association between haemoglobin concentration and nonverbal reasoning demonstrated that low haemoglobin levels are associated with lower scores. A quadratic relationship was found for haemoglobin concentration and immediate memory scores in which low and high haemoglobin levels were associated with lower scores. Conclusions Haemoglobin concentration was found to have a significant linear association with nonverbal reasoning scores and a significant quadratic association with memory scores. The results from this study help to understand the association between haemoglobin and different aspects of cognition.

Abstract
Objectives This study reports the prevalence of anemia and investigates its associated correlates and outcomes among elderly hospitalized patients in a single hospital in Bahrain. Methods A retrospective study was conducted on 227 consecutive elderly patients admitted under general internal medicine in the biggest tertiary hospital in Bahrain. Medical records were reviewed for all patients, including clinical characteristics, laboratory results, and outcomes. Results Anemia was highly prevalent among hospitalized elderly patients (71.6%). Males were significantly more affected than females (p = 0.031). In terms of severity, the most common type was moderate anemia (56.1%); with regards to etiology, the most common type was anemia associated with chronic disease (48.1%). Anemia was as common as other comorbidities, including hypertension (71.4%) and diabetes mellitus (53.7%). When comparing anemic to non-anemic patients, the length of hospital stay was significantly longer (p < 0.001) and inversely correlated to the level of hemoglobin; furthermore, 1-year mortality was significantly higher (p < 0.001). When compared to those with mild anemia, patients with moderate/severe anemia were more likely to die (odds ratio [OR] = 2.2, 95% confidence interval [CI]: 1.27–4.92). Conclusion The prevalence of anemia in our study was higher than previously reported. Even so, anemia receives minimal attention and is usually seen as a minor problem. Our results reiterate the need to recognize the high importance of anemia especially when diagnosing and treating older patients. This, in turn, could positively affect a number of outcomes such as mortality, length of stay, and the functional decline of admitted individuals.

Abstract
Introduction: The association patterns of hemoglobin (HB) concentrations with mortality among the longevity older adults are unclear. We aimed to evaluate the relationship among older adults form Chinese longevity regions. Methods: We included 1,785 older adults aged ≥65 years (mean age, 86.7 years; 1,002 women, 783 men) from the community-based Chinese Longitudinal Healthy Longevity Survey. We estimated the hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality using multivariable Cox proportional hazards models and Cox models with restricted cubic spline. Results: In total, 999 deaths occurred during a median follow-up of 5.4 years from 2011 to 2017. Restricted cubic spline analysis found no non-linear association between HB concentrations and all-cause mortality after a full adjustment for covariates among the older adults form longevity regions (p > 0.05 for non-linearity). The risk for all-cause mortality was significantly higher in the groups with HB concentration of <11.0 g/dL (HR: 1.37, 95% CI: 1.10-1.70) and 11.0-12.0 g/dL (HR: 1.25, 95% CI: 1.01-1.54); the risk of all-cause mortality was significantly lower in the groups with HB concentration ≥14.0 g/dL (HR: 0.76, 95% CI: 0.60-0.97) compared with the reference group (13.0-13.9 g/dL). Conclusions: Among older adults form Chinese longevity regions, HB concentrations were found to be inversely and linearly associated with all-cause mortality. Further prospective intervention trials are needed to confirm whether higher HB concentrations had a lower risk of mortality in these older adults.

Abstract
Introduction The mortality of femoral neck fracture (FNF) is high and every effort should be made to identify and manage any possible risk factors. The aim of this study was to evaluate whether on-admission hemoglobin (Hb) level, C-reactive protein (CRP), and serum creatinine were associated with 2-year mortality after FNF. Patients and Methods In this retrospective observational cohort study, we considered for inclusion all displaced FNF patients 65 years and above treated with hemi-arthroplasty between February 2011 and May 2015. We documented the age, sex, cognitive status, and American Society of Anesthesiologists (ASA) classification. The Hb level, CRP, and serum creatinine were measured. The medical records were followed up for 2 years. We fitted different crude and adjusted Cox proportional hazards models to examine whether Hb level <100 g/L, CRP >20 mg/L, and serum creatinine >100 μmol/L were associated with the 2-year mortality, adjusted for age, sex, and ASA class. Results A total of 290 patients [208 females (72%), mean age 84 years] were included in the study. More than 50% of patients had impaired cognition and ASA class 3–4. Of the 290 patients, 38.3% (n = 111) had died within 2 years after surgery. Mortality among males was 46.3% (n = 38) while mortality among females was 35,1% (n = 73), p = 0.07. We found that on-admission Hb level <100 g/L was associated with 2-year mortality (HR = 3.3, 95% CI: 1.3–8.3, p < 0.01) while CRP >20 mg/L and serum creatinine >100 μmol/L were not associated with 2-year mortality (p = 0.89 and p = 0.31, respectively). Conclusion On-admission Hb level <100 g/L, but not CRP >20 mg/L and serum creatinine >100 μmol/L, was associated with 2-year mortality. These results can help healthcare providers identify high-risk FNF patients who probably would benefit from optimized perioperative medical management.

Marzban M, Nabipour I, Farhadi A, Ostovar A, Larijani B, Darabi AH, Shabankari E, Gholizade M. Association between anemia, physical performance and cognitive function in Iranian elderly people: evidence from Bushehr Elderly Health (BEH) program. BMC Geriatr 2021; 21:329. [PMID: 34030664 PMCID: PMC8142505 DOI: 10.1186/s12877-021-02285-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 05/11/2021] [Indexed: 12/19/2022] Open
Abstract
Background and objectives The present study aimed to investigate the relation between anemia and hemoglobin (Hgb) concentration, physical performance, and cognitive function in a large sample of Iranian elderly population. Methods Data were collected from Bushehr elderly health (BEH) program. A total of 3000 persons aged ≥60 years were selected through multistage random sampling. Hemoglobin values lower than 12 and 13 g/dL were considered as anemia for women and men, respectively. The cognitive function was measured using the Mini-cog test and Category fluency test (CFT), and the physical function was measured using handgrip strength (muscle strength), Relative handgrip strength (RHGS), and 4.57-m usual gait speed. Univariate and adjusted multivariate logistic regression and linear regression with Stata MP (version 15) were run, and a p-value of < 0.05 was used as statistically significant for all analyses. Results Among participants, 7.43% were anemic, and 115 (51.57%) simultaneously had anemia and cognitive disorder. There were significant associations between red blood cell count (RBC), hemoglobin (Hgb), platelet count (PLT), and hematocrit percentage (HCT) with cognitive impairment. Additionally, Hgb concentration was significantly associated with all physical measures (Mean handgrip, Relative handgrip, and usual gait speed) and late recall (mini-cog) among the whole participants. This association remained statistically significant after considering multi-cofounders. In contrast, after stratifying the participants by gender, the association between Hgb concentration and usual gait speed was decreased in both men and women; moreover, Hgb association with cognitive measures (category fluency test and late recall) was no longer significant (all p-values > 0.05). Conclusion There was a cross-sectional and significant association between anemia and functional variables (e.g., Relative and mean handgrip) in Iranian elderly population, whereas Semantic memory, Late recall, and walking were more affected by gender.

Abstract
Background Anemia, which is a major public health problem worldwide, represents a decline in the oxygenation function, and can therefore be related to low strength. However, hemoglobin cannot repair muscles directly, but is beneficial only in a supportive role. Previous studies on the relationship between handgrip strength and anemia have been controversial. Thus, we aimed to analyze the association between handgrip strength and anemia in Korean adults. Methods This cross-sectional study used the 2013–2017 data from the 6th and 7th Korean National Health and Nutrition Examination Survey (KNHANES) that included 16,638 Korean adults, aged ≥19 years, who met the inclusion or exclusion criteria. Differences in sociodemographic factors (sex, age, education, income, and employment), lifestyle factors (alcohol consumption, smoking, and physical activity), and illness and health factors [body mass index (BMI), vitamin intake, iron intake, comorbid illnesses, and handgrip strength] by existence of anemia, were analyzed using the Chi square test. Binary logistic regression analysis was used to measure the association between handgrip strength and anemia, while adjusting for other possible confounders. Subgroup analysis, stratified by sex and age, was performed. Results Among Korean adults aged ≥19 years, 745,296 (7.7%) had anemia. A higher odds ratio, adjusted for other covariates/factors (OR) of anemia occurred in the weak handgrip strength group than in the strong handgrip strength group (OR = 1.92, 95% CI: 1.58–2.33). The subgroup analysis showed a higher OR adjusted for other covariates/factors of anemia in the weak handgrip strength group than in the strong handgrip strength group, regardless of sex or age. However, the association was greater for males (OR = 2.13, 95% CI: 1.35–3.34) and for those aged ≥65 years (OR = 1.92, 95% CI: 1.42–2.58). Conclusion This study showed a strong association between handgrip strength and anemia that was particularly strong for males and those aged ≥65 years.

Abstract
Purpose COPD is a multisystem disease and there is a need for clinical serum markers that can assess the decline in lung and muscle function in COPD. The goal of this study was to evaluate the potential association of serum club-cell protein 16 (CC16), α-1 acid glycoprotein (AGP) and total sialic acid (TSA) with spirometry, hand-grip strength and quality of life to assess important disease outcomes. Methods This is a population-based cross-sectional study and data were collected from the patients at teaching hospitals of Gomal University and the University of Health Sciences in Pakistan. The study population included 1582 participants (Non-COPD; N = 788, COPD; N = 845) >55 years of age from both sexes, with data from structural interviews, clinical examinations, laboratory investigations, spirometry and hand-grip strength measurements. Results Serum TSA and CC16 were significant predictors of FEV1% (p < 0.05) and hand-grip strength in advanced stages of COPD (p < 0.05 each) in both sexes. Men had higher absolute and adjusted hand-grip strength than women in all groups (p < 0.05). Hand-grip strength was significantly associated with FEV1% in both genders (p < 0.05) with stronger effect in women (r2 = 0.075). Serum HDL-C was an independent predictor of hand-grip strength and FEV1% (p < 0.05) in both genders. Participants with extreme problem on EQ-5D parameters had more severe COPD and reduced hand-grip strength (all p values < 0.05). Conclusion Taken together, these studies show that the serum expressions of TSA and CC16 have correlations with spirometry and muscle decline in COPD. Further studies should be conducted to establish their efficacy in monitoring disease progression in COPD.

Abstract
OBJECTIVES Although anemia and activities of daily living (ADL) disability in female elderly are common conditions and are more likely to occur as people age, little is known about the association of anemia with ADL in female centenarians. The objective of this study was to examine the relationship between anemia and ADL disability in Chinese female centenarians. DESIGN, SETTING AND PARTICIPANTS We conducted a population-based cross-sectional study of a sample of 822 Chinese female centenarians from 2014 to 2016. MEASUREMENTS Blood analysis, home interview, and physical examination were performed following standard procedures. ADL disability was defined as a Barthel Index total score≤60. RESULTS The prevalence of anemia and ADL disability were 66.8% and 29.7% respectively in Chinese female centenarians. Multiple logistic regression analyses revealed that inflammation (OR = 2.280, 95% CI, 1.524-3.410), underweight (OR = 1.653, 95% CI, 1.186-2.303), anemia (OR = 1.775, 95% CI, 1.250-2.521), and living with family (OR = 0.518, 95% CI, 0.302-0.888) were significant factors related to ADL disability. Centenarians with severe anemia had an approximately fourfold greater likelihood of ADL disability than those without anemia (OR =3.747; 95% CI 1.525-9.206). An apparent dose-response relationship was found between anemia and ADL disability. CONCLUSION These findings may provide some insights into targeted intervention for maintaining ADL independence in female centenarians, especially encouraging the interventions of anemia to improve ADL.

Abstract
BACKGROUND Anemia may be an independent risk factor of death. Therefore, the current meta-analysis aimed to explore the relationship of anemia with all-cause mortality (ACM) and cardiovascular mortality (CVM) to provide evidence-based medical facts. METHODS Three major electronic databases, the National Library of Medicine of the USA (PubMed), Cochrane Library and Embase, were searched from inception to October 2018. Relevant studies were screened in strict accordance with the inclusion and exclusion criteria, and the pooled hazard ratios (HRs) together with the 95% confidence intervals (CIs) were performed to assess the statistically significant difference of anemia compared with ACM and CVM. RESULTS A total of 15 related studies were included. Our results suggested that among the mixed population regardless of sex, age and cardiovascular diseases (CVD), the ACM and CVM of anemia patients were increased, with the HRs and 95% CIs of 1.41 (1.33, 1.50) and 1.33 (1.23, 1.45), respectively. Meanwhile, the ACM of anemia patients with the mean age of over 65 or below 65 years was increased irrespective of sex and CVD, with the HRs and 95% CIs of 1.43 (1.26, 1.61) and 1.41 (1.32, 1.50), separately. Moreover, the risks of ACM were increased in male, female and mixed sex anemia patients despite age and CVD, with the HRs and 95% CIs of 1.39 (1.29, 1.49), 1.25 (1.20, 1.30) and 1.53 (1.39, 1.68), respectively. All patients with CVD and no CVD were associated with an increased risk of ACM regardless of age and sex, with the HRs and 95% CIs of 1.42 (1.33, 1.51) and 1.38 (1.16, 1.63), respectively. CONCLUSIONS Anemia is a risk factor to predict ACM and CVM among the general population, which is independent of sex, age, and history of CVD.

Cross-sectional relationship between haemoglobin concentration and measures of physical and cognitive function in an older rural South African population. J Epidemiol Community Health 2018; 72:796-802.

Abstract
Background Age cohort differences in haemoglobin concentrations and associations with physical and cognitive performance among populations of lower income and middle-income countries have not previously been described. We examined the association between these factors among older men and women in rural South Africa. Methods We analysed cross-sectional data from a population-based study of rural South African men and women aged 40 and over (n=4499), with data drawn from questionnaire responses, a cognitive battery, objective physical function tests and blood tests. Anaemia was defined as a haemoglobin concentration <12 g/dL for women and <13 g/dL for men. We related haemoglobin concentrations to each of age, grip strength, walk speed and a latent cognitive function z-score for men and women separately. We used unadjusted correlations and linear models to adjust for comorbidities and inflammation. Results In total, 1042 (43.0%) women and 833 (40.1%) men were anaemic. Haemoglobin concentrations were inversely correlated with age for men but not for women; in adjusted analyses, haemoglobin was 0.3 g/dL lower per decade older for men (95% CI 0.2 to 0.4 g/dL). In adjusted analyses, haemoglobin concentration was independently associated with grip strength in women (B=0.391, 95% CI 0.177 to 0.605), but this did not reach significance in men (B=0.266, 95% CI −0.019 to 0.552); no associations were observed between haemoglobin levels and walk speed or cognitive score. Conclusions Anaemia was prevalent in this study population of middle-aged and older, rural South African adults, but in contrast to high-income countries, it was not associated with poor physical or cognitive function. Our findings need to be replicated in other populations.

Abstract
People aged 90 and older represent a fast-growing population segment who deserve specific attention and research. Aging is associated with a progressive decrease in hemoglobin concentration, which predicts adverse outcome, such as mortality, morbidity, frailty and disability. Whether this association is independent from increased prevalence of comorbidity, causing both anemia and reduced physical function is yet under debate. The aim of this study is to explore the relationship between hemoglobin concentration and self-reported disability and reduced physical performance in a community dwelling population of nonagenarians. Data presented were collected in the framework of the Mugello Study, a clinical epidemiologic survey of nonagenarians living in the Mugello area (Tuscany, Italy). 251 persons (177 women, age 93.2 ± 3.3 years; 74 men, age 92.2 ± 2.5 years) underwent a blood draw. Along with hemoglobin concentration, self-reported disability (basic and instrumental activities of daily living), physical performance (Short Physical Performance Battery), self-reported physical activity and muscular strength (handgrip measurement) were assessed. Covariates, inherent sociodemographic and health indicators and comorbidities were also included in the analysis. This study confirms that anemia is very common in the oldest old, with a significantly higher prevalence in males (50% in men vs 24% in women). Multiple linear regression analysis, including all the comorbid conditions as confounding factors, shows that hemoglobin concentration is independently associated with handgrip strength, self-reported physical activity and disability in dressing, and taking a shower/bath. In conclusion, results from this study confirm that in the oldest old, low hemoglobin concentration is strongly associated with self-reported disability and decline of physical performance independent of comorbidity.

Abstract
BACKGROUND Frailty has emerged as a key medical syndrome predictive of comorbidity, disability, institutionalization and death. As a component of the five frailty phenotype diagnostic criteria, patient grip strength deserves attention as a simple and objective measure of the frailty syndrome. The aim of this study was to assess conditions that influence grip strength in geriatric inpatients. PATIENTS AND METHODS The study group consisted of 80 patients aged 78.6±7.0 years [Formula: see text], with 68.8% women, admitted to the Department of Geriatrics. A comprehensive geriatric assessment was complemented with assessment for the frailty phenotype as described by Fried et al for all patients in the study group. Functional assessment included Barthel Index of Activities of Daily Living (Barthel Index), Instrumental Activities of Daily Living Scale and Mini-Mental State Examination. RESULTS Three or more frailty criteria were positive in 32 patients (40%), while 56 subjects (70%) fulfilled the frailty criterion of weakness (grip strength test). Multivariate linear regression analysis revealed that two independent measures showed positive association with grip strength - Mini-Mental State Examination score (β=0.239; P=0.001) and statin use (β=0.213; P=0.002) - and four independent measures were negatively associated with grip strength - female sex (β=-0.671; P<0.001), C-reactive protein (β=-0.253; P<0.001), prior myocardial infarction (β=-0.190; P=0.006) and use of an antidepressant (β=-0.163; P=0.018). Low physical activity was identified as the only independent qualitative frailty component associated with 2-year mortality in multivariate logistic regression analysis after adjustment for age and sex (odds ratio =6.000; 95% CI =1.357-26.536; P=0.018). CONCLUSION Cognitive function, somatic comorbidity and medical treatment affect grip strength as a measure of physical frailty in geriatric inpatients. Grip strength was not predictive of 2-year mortality in this group.
