Abstract Background One in three older adults fall each year leading to increased disability, hospitalizations and mortality. Recent studies suggested an increased risk of falls among obese individuals which may correlate with increased rates of falls hospitalizations. However, there is not much information supporting the hypothesis that obesity may influence the risk of falls related hospitalizations. Aims To prospectively investigate whether body mass index (BMI) is a predictor for falls hospitalization by age group in the population of the EPIC-Norfolk Study. Methods Body height and weight were measured at baseline and BMI calculated. Falls hospitalization status over 20 years’ follow-up was ascertained using data linkage with centralized NHS records. Participants were categorized into the four BMI groups: underweight (BMI <18.5kg/m2 ), normal (18.5 ≤ BMI < 25.0 kg/m2), overweight ( 25.0 ≤ BMI < 30.0 kg/m2 ) and obese ( BMI ≥ 30.0kg/m2 ), and according to three age groups ( < 55 years, 55-64 years, ≥ 65 years). Results Data from 25636 individuals, (54.7%) women and (45.3%) men, mean age 59.2 ± 9.3 years, were included. For individuals within the under 55-year age group at baseline, individuals who were overweight (HR = 1.25; 95% CI= 1.01-1.56) and obese (HR = 1.54; 95% CI= 1.17-1.81) were at higher risk of falls hospitalization compared with those with normal BMI. As for individuals aged ≥ 65 years at recruitment, individuals who were obese were less likely to be hospitalized after a fall (HR = 0.85; 95% CI= 0.74 – 0.97) compared to those with normal BMI. Conclusions The relationship between obesity and falls hospitalization over 20 years differed between those aged <55years and 65years, with an increased risk observed for those <55years and reduced risk in those 65years. The underlying rationale for this finding will need to be evaluated in future studies.

Abstract Background Anemia is common in older adults and associated with greater morbidity and mortality. The causes of anemia in older adults have not been completely characterized. Although elevated circulating growth and differentiation factor 15 (GDF-15) has been associated with anemia in older adults, it is not known whether elevated GDF-15 predicts the development of anemia. Methods We examined the relationship between plasma GDF-15 concentrations at baseline in 708 non-anemic adults, aged 60 years and older, with incident anemia during 15 years of follow-up among participants in the Invecchiare in Chianti (InCHIANTI) Study. Results During follow-up, 179 (25.3%) participants developed anemia. The proportion of participants who developed anemia from the lowest to highest quartile of plasma GDF-15 was 12.9%, 20.1%, 21.2%, and 45.8%, respectively. Adults in the highest quartile of plasma GDF-15 had an increased risk of developing anemia (Hazards Ratio 1.15, 95% Confidence Interval 1.09, 1.21, P<.0001) compared to those in the lower three quartiles in a multivariable Cox proportional hazards model adjusting for age, sex, serum iron, soluble transferrin receptor, ferritin, vitamin B12, congestive heart failure, diabetes mellitus, and cancer. Conclusions Circulating GDF-15 is an independent predictor for the development of anemia in older adults.

Older adults commonly walk slower, which many believe helps improve their walking stability. However, they remain at increased risk of falls. We investigated how differences in age and walking speed independently affect dynamic stability during walking, and how age-related changes in leg strength and ROM affected this relationship. Eighteen active healthy older and 17 younger adults walked on a treadmill for 5 minutes each at each of 5 speeds (80–120% of preferred). Local divergence exponents and maximum Floquet multipliers (FM) were calculated to quantify each subject’s responses to small inherent perturbations during walking. These older adults exhibited the same preferred walking speeds as the younger subjects (p = 0.860). However, these older adults still exhibited greater local divergence exponents (p<0.0001) and higher maximum FM (p<0.007) than young adults at all walking speeds. These older adults remained more unstable (p<0.04) even after adjusting for declines in both strength and ROM. In both age groups, local divergence exponents decreased at slower speeds and increased at faster speeds (p<0.0001). Maximum FM showed similar changes with speed (p<0.02). The older adults in this study were healthy enough to walk at normal speeds. However, these adults were still more unstable than the young adults, independent of walking speed. This greater instability was not explained by loss of leg strength and ROM. Slower speeds led to decreased instability in both groups.

Vitamin D requirements are thought to vary with age, but there is little comparative evidence for this. One goal in establishing a vitamin D requirement is to avoid secondary hyperparathyroidism. We studied 1741 euthyroid, thyroid clinic outpatients without evidence of calcium abnormalities, ranging in age from 19 to 97 yr, whose serum and urine had been analyzed for calcium, vitamin D, and parathyroid status. We found no effect of age on the 25-hydroxyvitamin D [25(OH)D] concentration associated with specific vitamin D intakes, and there was no relationship between 25(OH)D and 1,25hydroxyvitamin D [1,25(OH)2D]. In every age group, serum 1,25(OH)2D declined with increasing creatinine (P < 0.001). What changed with age included creatinine, which correlated with 25(OH)D (r = 0.146, P < 0.001) only in the youngest age group (19–50 yr) but not in the older age groups (P > 0.1). Creatinine did not correlate with PTH in the youngest age group, but the relationship became significant as age increased (e.g. for the elderly, r = 0.365, P < 0.001). Linear regression of log PTH vs. log 25(OH)D agreed with the natural shape of the relationship observed with scatterplot smoothing, and this showed no plateau in PTH as 25(OH)D increased. We compared PTH concentrations among age groups, based on 20 nmol/liter increments in 25(OH)D. Mean PTH in adults older than 70 yr was consistently higher than in adults younger than 50 yr (P < 0.05 by ANOVA and Dunnett’s t test). PTH levels of the elderly who had 25(OH)D concentrations greater than 100 nmol/liter matched PTH of younger adults having 25(OH)D concentrations near 70 nmol/liter. This study shows that all age groups exhibit a high prevalence of 25(OH)D insufficiency and secondary hyperparathyroidism. Older adults are just as efficient in maintaining 25(OH)D, but they need more vitamin D to produce the higher 25(OH)D concentrations required to overcome the hyperparathyroidism associated with their diminishing renal function.

ABSTRACTAlthough the factors that influence people's perception of happiness have long been a focus for scholars, research to date has not offered conclusive findings on the relationships between income, age and happiness. This study examined the relationship between money and happiness across age groups. Analysing data from United States General Social Surveys from 1972 to 2006, this study finds that even after controlling for all the major socio-demographic variables, income (whether household income or personal equivalised income) had a significant positive association with happiness for young and middle-age adults, but it was not the same case with older adults. After controlling for the major socio-demographic variables, there was no evidence of a significant relationship between income (whichever definition) and happiness for older adults. The results also showed that the effect of household income on happiness was significantly smaller for older adults than for young or middle-age adults in the model controlling for major socio-demographic variables. The relationship between household income and happiness no longer differed significantly across age groups after social comparison variables were included. The relationship between equivalised income and happiness did not vary significantly by age group after controlling for the major socio-demographic variables.

BACKGROUND Older adults tend to experience difficulties in switching quickly between various reliable sensory inputs, which ultimately may contribute to an increased risk of falls and injuries. Sideward falls are the most frequent cause of hip fractures among older adults. Recently, exergame programs have been confirmed as beneficial tools for enhancing postural control, which can reduce the risk of falls. However, studies to explore more precisely which mechanism of exergaming directly influences older women’s ability to balance are still needed. OBJECTIVE Our aim was to evaluate, in a single-group pretest/posttest/follow-up usability study, whether Kinect exergame balance training might have a beneficial impact on the sensory reweighting in women aged over 60. METHODS A total of 14 healthy women (mean age 69.57 [SD 4.66] years, mean body mass index 26.21 [SD 2.6] kg/m<sup>2</sup>) participated in the study. The volunteers trained with the commercially available games of Kinect for Xbox 360 console 3 times (30 minutes/session) a week over a 6-week period (total of 18 visits). Participants’ postural sway in both the anteroposterior (AP) and mediolateral (ML) directions was recorded with NeuroCom Balance Master 6.0. To assess and measure postural sensory reweighting, the Modified Clinical Test of Sensory Interaction in Balance was used, where volunteers were exposed to various changes in visual (eyes open or eyes closed) and surface conditions (firm or foam surface). RESULTS In the ML direction, the Kinect exergame training caused a significant decrease in the sway path on the firm surface with the eyes open (<i>P</i>&lt;.001) and eyes closed (<i>P</i>=.001), and on the foam surface with the eyes open (<i>P</i>=.001) and eyes closed (<i>P</i>&lt;.001) conditions compared with baseline data. The follow-up measurements when compared with the baseline data showed a significant change in the sway path on the firm surface with the eyes open (<i>P</i>&lt;.001) and eyes closed (<i>P</i>&lt;.001) conditions, as well as on the foam surface with the eyes open (<i>P</i>=.003) and eyes closed (<i>P</i>&lt;.001) conditions. Besides, on the firm surface, there were no significant differences in sway path values in the AP direction between the baseline and the posttraining measurements (eyes open: <i>P</i>=.49; eyes closed: <i>P</i>=.18). Likewise, on the foam surface, there were no significant differences in sway path values in the AP direction under both eyes open (<i>P</i>=.24) and eyes closed (<i>P</i>=.84) conditions. CONCLUSIONS The improved posturography measurements of the sway path in the ML direction might suggest that the Kinect exergame balance training may have effects on sensory reweighting, and thus on the balance of women aged over 60. Based on these results, Kinect exergaming may provide a safe and potentially useful tool for improving postural stability in the crucial ML direction, and thus it may help reduce the risk of falling.

ABSTRACTBackground:The aim of this study was to test the association between anxiety at the time of hospitalization and falls occurring within one month of discharge, and to offer potential mechanisms for this association.Methods:One-month, prospective cohort study of 556 older adults in two medical centers in Israel. Anxiety and functional decline were assessed during hospitalization and falls were assessed one month post-discharge.Results:A total of 72 (12.9%) participants reported at least one fall during the 30-day post-discharge period. Controlling for demographics, functional decline and pre-morbid functional status, the odds of falls between discharge, and 1-month follow-up were almost twice as high among patients with anxiety symptoms (OR = 1.89, 95% CI: 1.04-3.48) compared with those who screened negative for anxiety. After accounting for in-hospital functional decline, the relationship between anxiety symptoms and falls decreased by 11% (from OR = 2.13 to 1.89), indicating that the relationship between anxiety and falls was partially mediated by functional decline during hospitalization.Conclusions:Anxiety at time of hospitalization is associated with falls 30-days post-discharge, controlling for several well-known confounders. This relationship is partially mediated by functional decline. Identifying patients with anxiety for inclusion in targeted rehabilitation interventions may be an important component of fall prevention strategies.

There are limited data on the relationship of acute dental infections with hospitalisation and new-onset atrial fibrillation (AF). This study aimed to assess the relationship between acute periapical abscess and incident AF. This was a retrospective cohort study from a French national database of patients hospitalized in 2013 (3.4 million patients) with at least five years of follow up. In total, 3,056,291 adults (55.1% female) required hospital admission in French hospitals in 2013 while not having a history of AF. Of 4693 patients classified as having dental periapical abscess, 435 (9.27%) developed AF, compared to 326,241 (10.69%) without dental periapical abscess that developed AF over a mean follow-up of 4.8 ± 1.7 years. Multivariable analysis indicated that dental periapical abscess acted as an independent predictor for new onset AF (p < 0.01). The CHA2DS2VASc score in patients with acute dental periapical abscess had moderate predictive value for development of AF, with Area Under the Curve (AUC) 0.73 (95% CI, 0.71–0.76). An increased risk of new onset AF was identified for individuals hospitalized with dental periapical abscess. Careful follow up of patients with severe, acute dental periapical infections is needed for incident AF, as well as investigations of possible mechanisms linking these conditions.
