Abstract
The first years of retirement have often been seen as a typical time window to take up (or intensify) voluntary work. Due to the changing context of retirement and historical differences in resources, the role of retirement for volunteering may have changed with historical time. We compared individuals aged 60-70 in five cross-sectional waves (1999, 2004, 2009, 2014, 2019) of the German Survey on Volunteering (Deutscher Freiwilligensurvey: FWS) to investigate how the association of retirement status and volunteering has changed. We found a negative association of retirement and volunteering, which was not significant once controlling for age, education, gender and region. While engagement levels seem to have increased with historical time, voluntary work seems to have become less time consuming. There were no historical differences in the association of retirement and volunteering. Our results highlight the role of historical time and contextual factors when investigating volunteering and post-retirement activities.

Abstract
OBJECTIVES Life-span perspectives have long acknowledged that individual functioning is shaped by historical and sociocultural contexts. Secular increases favoring recent cohorts are widely documented. However, little is known about secular trends in day-to-day activities and whether historical changes have occurred in younger and older adults alike. METHODS We compared data from 2 independent cohort samples of the daily diary portion of the Midlife in the United States Study obtained 18 years apart (1995/1996 cohort: n = 1,499 vs 2013/2014 cohort: n = 782) and identified case-matched cohorts (n = 757 per cohort) based on age, gender, education, and race. An activity diversity score was calculated based on 7 common daily activities, using Shannon's entropy method. We additionally examined the roles of age and other sociodemographic and health characteristics in cohort differences in activity diversity. RESULTS Results revealed that the 2013/2014 cohort experienced lower daily activity diversity than the 1995/1996 cohort. Age was positively associated with activity diversity in the 1995/1996 cohort, whereas age was negatively associated with activity diversity in the 2013/2014 cohort. These associations were significant for those who were older than age 55. Cohorts also differed in the types of most dominant activities and average time spent on those activities. DISCUSSION Findings show changes in the lifestyles and daily activities of U.S. adults across 2 decades. Contrasting to the common belief that today's adults may be healthier and more active, they seem engaging in less diverse daily activities, which can be a risk for future health outcomes.

Abstract
Background The American Heart Association's Life's Essential 8 (LE8) is an updated construct of cardiovascular health (CVH), including blood pressure, lipids, glucose, body mass index, nicotine exposure, diet, physical activity, and sleep health. It is challenging to simultaneously measure all eight metrics at multiple time points in most research and clinical settings, hindering the use of LE8 to assess individuals' overall CVH trajectories over time. Materials and methods We obtained data from 5,588 participants in the Nurses' Health Studies (NHS, NHSII) and Health Professionaĺs Follow-up Study (HPFS), and 27,194 participants in the 2005-2016 National Health and Nutrition Examination Survey (NHANES) with all eight metrics available. Individuals' overall cardiovascular health (CVH) was determined by LE8 score (0-100). CVH-related factors that are routinely collected in many settings (i.e., demographics, BMI, smoking, hypertension, hypercholesterolemia, and diabetes) were included as predictors in the base models of LE8 score, and subsequent models further included less frequently measured factors (i.e., physical activity, diet, blood pressure, and sleep health). Gradient boosting decision trees were trained with hyper-parameters tuned by cross-validations. Results The base models trained using NHS, NHSII, and HPFS had validated root mean squared errors (RMSEs) of 8.06 (internal) and 16.72 (external). Models with additional predictors further improved performance. Consistent results were observed in models trained using NHANES. The predicted CVH scores can generate consistent effect estimates in associational studies as the observed CVH scores. Conclusions CVH-related factors routinely measured in many settings can be used to accurately estimate individuals' overall CVH when LE8 metrics are incomplete.

Abstract
OBJECTIVE Pain is a very common chronic condition in late life that is associated with poorer quality of life and greater functional restrictions. Little is known regarding temporal trends in pain prevalence and pain intensity. Therefore, we estimated trends in pain prevalence and intensity over time among German middle-aged and older adults. METHODS We used two independent samples drawn in different years from the German Ageing Survey, which is a nationwide population-representative study with a cohort-sequential design. Specifically, a sample of individuals aged 40-85 years who were assessed in 2008 (n = 5961) was compared with a sample of individuals with the same age range who were assessed in 2014 (n = 5809). Individuals were asked if and to what extent they had experienced constant or recurrent pain within the past four weeks. χ2 tests and regression analyses were computed. RESULTS In 2008, about 44% of all individuals reported suffering from at least very mild pain. In 2014, this proportion was higher by about 7%. Controlling for chronological age, gender, education, region of residence (West vs. East Germany), depressive symptoms, chronic diseases, BMI, and physical activity, the difference in pain prevalence and pain intensity between the samples remained statistically significant. CONCLUSION Our data suggest an increase in the prevalence and intensity of pain among middle-aged and older German adults between 2008 and 2014, which remained statistically significant when controlling for socio-demographic and health-related indicators. Further research is needed to identify the factors underlying this increasing pain prevalence and pain intensity in order to counteract this negative temporal trend.

Abstract
History-graded increases in older adults' levels of cognitive performance are well documented, but little is known about historical shifts in within-person change: cognitive decline and onset of decline. We combined harmonized perceptual-motor speed data from independent samples recruited in 1990 and 2010 to obtain 2,008 age-matched longitudinal observations (M = 78 years, 50% women) from 228 participants in the Berlin Aging Study (BASE) and 583 participants in the Berlin Aging Study II (BASE-II). We used nonlinear growth models that orthogonalized within- and between-person age effects and controlled for retest effects. At age 78, the later-born BASE-II cohort substantially outperformed the earlier-born BASE cohort (d = 1.20; 25 years of age difference). Age trajectories, however, were parallel, and there was no evidence of cohort differences in the amount or rate of decline and the onset of decline. Cognitive functioning has shifted to higher levels, but cognitive decline in old age appears to proceed similarly as it did two decades ago.

Abstract
Biomarkers defining biological age are typically laborious or expensive to assess. Instead, in the current study, we identified parameters based on standard laboratory blood tests across metabolic, cardiovascular, inflammatory, and kidney functioning that had been assessed in the Berlin Aging Study (BASE) (n = 384) and Berlin Aging Study II (BASE-II) (n = 1517). We calculated biological age using those 12 parameters that individually predicted mortality hazards over 26 years in BASE. In BASE, older biological age was associated with more physician-observed morbidity and higher mortality hazards, over and above the effects of chronological age, sex, and education. Similarly, in BASE-II, biological age was associated with physician-observed morbidity and subjective health, over and above the effects of chronological age, sex, and education as well as alternative biomarkers including telomere length, DNA methylation age, skin age, and subjective age but not PhenoAge. We discuss the importance of biological age as one indicator of aging.

Abstract
OBJECTIVE Thyroid dysfunction is associated with relevant disturbances in glucose metabolism. Moreover, thyroid function undergoes important changes with ageing. The objective of this study was to investigate the association of thyroid function with insulin resistance with particular consideration of possible age-related effect modifications. DESIGN A sample of 4193 participants from two independent epidemiological studies, the Study of Health in Pomerania-TREND-0 and the Berlin Aging Study II, was included in this cross-sectional analysis. METHODS Insulin resistance was estimated by homeostasis model of insulin resistance (HOMA-IR) and the insulin sensitivity index (ISI). Associations of thyroid biomarkers (thyroid-stimulating hormone, free thyroxine, and free triiodothyronine (fT3)) with parameters of glucose metabolism were analysed by regression models adjusted for age, sex, smoking status, and study site. RESULTS A higher fT3 was significantly associated with higher fasting glucose and higher fasting and 2-h postload insulin levels, a higher HOMA-IR, and lower ISI. A higher fT3 was also associated with a higher risk for impaired fasting glucose (RR 1.09, 95 CI 1.02; 1.18; P = 0.017). Many of these associations between thyroid markers and parameters of glucose metabolism were significant in young and middle-aged participants but not in older individuals. CONCLUSIONS The main finding of this study was a consistent association of fT3 with almost all markers of insulin resistance. However, this effect seems to be wearing off in higher age highlighting a potential age-related modification of the interaction between thyroid function and glucose metabolism. Further studies are needed to clarify causal relationships.

Abstract
OBJECTIVES We aimed at examining between-person and within-person associations across age trajectories of perceptual speed and loneliness in old age. METHOD We applied multilevel models to 4 waves of data collected over 6 years from 1,491 participants of the Berlin Aging Study II (60-88 years at baseline, 50% women) to disentangle between-person and within-person associations across age trajectories of perceptual speed and both emotional and social loneliness. Sex and education were considered as relevant individual characteristics and included as covariates in the model. RESULTS Analyses revealed that on average perceptual speed exhibited moderate within-person age-related declines, whereas facets of loneliness were rather stable. Perceptual speed did not predict age trajectories of emotional or social loneliness, at either the between- or within-person level. In contrast, loneliness discriminated individuals at the between-person level, such that those feeling emotionally or socially more lonely showed lower cognitive performance than those feeling emotionally or socially less lonely. Predictive effects of social loneliness were stronger for relatively young people (i.e., in their mid to late 60s) than for relatively older participants (i.e., in their 80s). In addition, predictive effects of social loneliness for perceptual speed at the within-person level were modest and deviated in direction and size from between-person social loneliness effects among those in their mid- to late 60s, whereas they did not among those in their 80s. DISCUSSION We conclude that loneliness may serve as a precursor for basic cognitive functioning in old age and suggest routes for further inquiry.

Cardiovascular health is associated with the epigenetic clock in the Berlin Aging Study II (BASE-II). Mech Ageing Dev 2021; 201:111616. [PMID: 34879249 DOI: 10.1016/j.mad.2021.111616] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 11/11/2021] [Accepted: 12/02/2021] [Indexed: 02/08/2023]
Abstract
The epigenetic clock parameter DNAm age acceleration is a promising biomarker of aging. We have recently described an epigenetic clock based on only seven cytosine-phosphate-guanine sites, which is highly associated with chronological age. The aim of this study was to examine this epigenetic clock with respect to its relationship with cardiovascular health (CVH) in older adults. We used data from the Berlin Aging Study II (BASE-II; 1,671 participants; 68.8 ± 3.7 years old). CVH was operationalized using two different CVH scores, the Framingham Risk Score (FRS), and the Life's simple 7 (LS7). To adjust for potential confounding, e.g. by sex, we performed regression analyses. The LS7 score was higher, i.e. more favorable, in woman than in men (8.8 ± 2 vs. 8.2 ± 2, p < 0.001). DNAm age acceleration was associated with the FRS (β = 0.122, p = 0.028) and with the LS7 (β = -0.804, p = 0.032). In more detail, physical activity (β = -0.461, p = 0.05), HDL-cholesterol (β = 0.343, p = 0.03) and total cholesterol (β = -0.364, p = 0.002) were associated with epigenetic age acceleration. We present evidence suggesting that better CVH is associated with decelerated biological aging measured by the epigenetic clock.

Abstract
PURPOSE To evaluate visual performance and optical quality of an extended depth-of-focus intraocular lens (EDoF IOL) compared with a monofocal aspheric IOL. SETTING Department of Ophthalmology, Charité-Medical University Berlin, Germany. DESIGN Prospective case series. METHODS After phacoemulsification, a total of 28 patients (56 eyes) underwent bilateral implantation of either the Mini Well (EDoF IOL) or the Mini 4 (monofocal IOL). Assessments including refraction, distance, intermediate and near visual acuity, defocus curves, contrast sensitivity, glare disability, higher-order aberrations (HOAs), and patient satisfaction were performed at 1 month and 3 months postoperatively. RESULTS Both study groups comprised 14 patients (28 eyes) each. At 3-month follow-up, the EDoF IOL showed better results in monocular uncorrected intermediate visual acuity (-0.04 vs 0.10 logMAR, P = .000) and in uncorrected near visual acuity (0.13 vs 0.36 logMAR, P = .000), whereas no statistically significant difference was found between groups in monocular uncorrected distance visual acuity (0.04 vs 0.00 logMAR, P = .110). The monocular depth of focus was 0.8 D greater in the Mini Well IOL group. Measurements of internal HOAs revealed a greater negative primary spherical aberration in the EDoF group at pupil sizes of 2.0 to 5.0 mm. At 5.0 mm, total internal HOAs did not differ statistically significantly (0.376 vs 0.340 μm root mean square, P = .068). CONCLUSIONS The Mini Well IOL provided greater depth of focus with superior outcomes at intermediate and near distances and comparable outcomes at far distance. Although inducing higher amounts of spherical aberration, it showed good results under low lighting conditions with little subjective dysphotopsia.

[PMID: 34011331 PMCID: PMC8135150 DOI: 10.1186/s12891-021-04291-9] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 04/19/2021] [Indexed: 01/05/2023] Open
Abstract
Background Demographic changes led to an increasingly ageing population in Germany and thus to possible changes in the frequency of fractures. The primary aim of this study was to report changes in fracture rates of the lower extremities in Germany in 2002 compared to 2017 and to evaluate those changes. Methods Inpatient data from the German National Hospital Discharge Registry (ICD10) for 2002 and 2017 were evaluated. Changes in total counts and incidence rates were analysed for fractures in the following locations: femoral neck, pertrochanteric, subtrochanteric, distal femur, femoral shaft, proximal and distal tibia, tibial shaft, medial and lateral malleolus, and other parts of the lower leg (including bi- and trimalleolar fractures), calcaneus, talus, other tarsal bones, metatarsal bones, greater toe, lesser toe, other fractures of foot or unspecific fractures of foot and toe. Patients were classed into age groups by sex: 15–24, 25–34,35–44, 45–54, 55–64, 65–74, 75–84, 85–90 and > 90 years. Results The total count for lower extremity fractures in men and women increased slightly by 4.5% from 305,764 in 2002 to 319,422 in 2017. Hip and femur fractures increased by 23.5% from 150,565 in 2002 to 185,979 in 2017. The number of these fractures among men increased by 46% and among women by 15.3%. The total count of lower leg fractures decreased by 15.4% from 131,162 in 2002 to 110,924 in 2017. Especially, younger age groups showed a decline for all tibial segments and ankle fractures. For both sexes, the number of lower leg fractures in those 75 years or older increased in all lower leg fracture locations. Most femur and lower leg fractures occurred in women. The incidence of fractures rose sharply from 2002 to 2017, especially for older cohorts. Conclusion The total numbers of lower extremity fractures increased slightly in 2017 compared to 2002 – especially hip and femur fractures among men. The incidence of almost all lower extremity fracture types among older people increased during this time. Women were particularly affected. Therefore, focused prevention programmes should be considered including an extended fracture spectrum in the elderly.

Abstract
In addition to biological sex, gender, defined as the sociocultural dimension of being a woman or a man, plays a central role in health. However, there are so far few approaches to quantify gender in a retrospective manner in existing study datasets. We therefore aimed to develop a methodology that can be retrospectively applied to assess gender in existing cohorts. We used baseline data from the Berlin Aging Study II (BASE-II), obtained in 2009-2014 from 1869 participants aged 60 years and older. We identified 13 gender-related variables and used them to construct a gender score by using primary component and logistic regression analyses. Of these, nine variables contributed to a gender score: chronic stress, marital status, risk-taking behaviour, personality attributes: agreeableness, neuroticism, extraversion, loneliness, conscientiousness, and level of education. Females and males differed significantly in the distribution of the gender score, but a significant overlap was also found. Thus, we were able to develop a gender score in a retrospective manner from already collected data that characterized participants in addition to biological sex. This approach will allow researchers to introduce the notion of gender retrospectively into a large number of studies.

Abstract
Background Obesity is associated with chronic low-grade inflammation leading to metabolic and cardiovascular diseases, but a subset of obese individuals is considered insulin sensitive (IS). The underlying pathophysiologic mechanisms remain elusive and clinical studies on the relationship between inflammatory markers and metabolically healthy obesity (MHO) are scarce. Methods In this cross-sectional analysis, we included a sample of 437 older participants (60–84 years) from the Berlin Aging Study II (BASE-II). Peripheral blood mononuclear cells were isolated, immune cell subsets were analyzed with multiparameter flow cytometry and systemic cytokine levels were measured. Immune cell parameters were correlated with metabolic measures and multiple linear regression analysis was conducted and adjusted for various demographic and clinical factors. Results We found that frequencies of naïve and memory CD4+ and CD8+ T cells inversely correlated with measures for insulin sensitivity in the older population. Moreover, the percentages of naïve CD4+ and CD8+ T cells were significantly higher, whereas activated T cells and IL-6 levels were lower in IS compared to insulin resistant (IR) obese individuals. The percentages of naïve CD4+ and CD8+ T cells were predictive for impaired insulin sensitivity (ß = 0.16, p = 0.01 and ß = 0.11, p = 0.04), and the association of naïve CD4+ T cells with insulin sensitivity persisted after multivariate adjustment (ß = 0.14, p = 0.02). Conclusions These findings support the hypothesis that parameters of systemic inflammation can differentiate IS from IR obese individuals that are at higher risk for cardiometabolic diseases and may have clinical implications with regard to obesity treatment stratification.

Abstract
INTRODUCTION Since it is well documented that spatiotemporal gait parameters are affected by body size, it is of limited clinical value to compare individual scores against reference values without taking body size into consideration. For older adults, reference values have been presented in recent reports, but unfortunately the effect of body size on gait characteristics was not taken into account and neither prediction intervals nor percentile ranks were included. It is the aim of this study to present and assess a model where individual spatiotemporal gait parameter values for older adults can be compared to reference values adjusted for gender, age, and body height. METHODS Reference gait data were collected from l464 older adults aged 69-80 years with no impairments believed to affect gait, stratified by gender, intermediately adjusted to a common body height using a pendulum model and entered into a simple regression model for each parameter with age as predictor. From the regression coefficients predicted gait parameter values could be back transformed to the individual body height of a new subject. Calculations were done using spreadsheet formulae and equations. RESULTS A spreadsheet based graphical user interface (GUI) has been developed in Microsoft Excel® where individual spatiotemporal gait data is entered for comparison with reference data taking gender, age and body height into account, and returning predicted point estimates with confidence intervals, prediction intervals, and percentile ranks. SIGNIFICANCE A GUI solution where individual spatiotemporal gait data is compared to reference data is feasible to researchers and for clinical use. To the best of our knowledge, this is the first model presented for comparison of basic gait parameters between individuals and reference data from older adults where gender, age, and body height are taken into account.

Abstract
Zusammenfassung
Hintergrund Diabetes mellitus Typ 2 (T2DM) und Sarkopenie nehmen mit steigendem Alter in ihrer Prävalenz zu und können langfristig betrachtet jeweils zu erheblichen gesundheitlichen und funktionellen Einschränkungen führen. Während eine zunehmende Insulinresistenz bei abnehmender Muskelmasse plausibel erscheint, sind umgekehrt auch glukotoxische negative Effekte auf die Skelettmuskulatur im Sinne einer sekundären Sarkopenie denkbar. Ziel dieser Arbeit war es, den Zusammenhang zwischen Sarkopenie, Insulinresistenz und T2DM bei älteren Menschen zu untersuchen.
Methoden Untersucht wurden 1555 Probanden der Berliner Altersstudie II (BASE-II) mit einem durchschnittlichen Alter von 68 ± 4 Jahren. Die Diagnose T2DM wurde basierend auf der Anamnese sowie oralem Glukosetoleranztest und HbA1c-Wert nach ADA-Kriterien gestellt und die Insulinresistenz wurde via Homeostatic Model Assessment for Insulin resistance (HOMA-IR) und Insulinsensitivitätsindex nach Matsuda (ISI) eingeschätzt. Die appendikuläre Skelettmuskelmasse (ALM) wurde mittels Dual-Röntgen-Absorptiometrie (DXA) und eine Sarkopenie mithilfe der anhand des Body-Mass-Index (BMI) korrigierten Muskelmasse (ALM/BMI) nach den Cut-off-Werten des FNIH Sarcopenia Project bestimmt. Gruppenvergleiche wurden mittels Kruskal-Wallis-Test berechnet, und der Zusammenhang zwischen Diabetes mellitus und Sarkopenie bzw. ALM und Insulinresistenz wurde mittels geeigneter Regressionsmodelle überprüft.
Ergebnisse 25,2 % der insgesamt 160 Probanden mit T2DM hatten bereits eine Sarkopenie. Sarkopenisch-adipöse Probanden wiesen im Vergleich zu nur adipösen, nur sarkopenen oder weder adipösen noch sarkopenen Probanden im Median einen niedrigeren ISI und einen höheren HOMA-IR auf (jeweils p < 0,001). T2DM zeigte sich unabhängig assoziiert mit Sarkopenie (OR 3,293, 95 %-KI 1,984–5,466, p < 0,001), während nach Ausschluss bekannter Diabetiker eine höhere ALM mit einem höheren ISI (B 0,229, 95 %-KI 0,119–0,338; p < 0,001), nicht jedoch niedrigerem HOMA-IR (B –0,017, 95 %-KI –0,089–0,055; p = 0,640) einherging.
Diskussion Sarkopenie ist sowohl mit Insulinresistenz als auch T2DM assoziiert. Die Frage bzgl. der Kausalität ist aufgrund des querschnittlichen Designs der Studie nicht zu beantworten, jedoch sollte eine mögliche Rolle des T2DM als sekundäre Sarkopenieursache berücksichtigt und weiter untersucht werden. Im Hinblick auf mögliche Folgen erscheinen die Identifizierung von Risikopatienten mit kombiniertem Auftreten von Sarkopenie und Insulinresistenz und die Evaluation basaler präventiver Maßnahmen wie gezieltes körperliches Training und angepasste Ernährung ein weiterführendes sinnvolles Ziel.

Abstract
Background Recent studies investigating fracture development in Germany are not available especially with regard to demographic change. The primary aim of this study was to report trends in fracture development of the upper extremity in Germany between 2002 and 2017 and to evaluate changes over time. Methods Evaluating inpatient data from the German National Hospital Discharge Registry (International Classification of Diseases, ICD-10) between 2002 and 2017. Total count, incidences and percentage changes of the following fracture localizations were analysed: proximal humerus, distal humerus, proximal ulna, proximal radius, ulna diaphysis (including Monteggia lesion) and distal radius. Ten age groups for men and women were formed: 35–44, 45–54, 55–64, 65–74; 75–84; 85–90, and > 90 (years). Results The total count of proximal humeral fractures increased from 40,839 (2002, men/women 9967/30,872) to 59,545 (2017, men/women 14,484/45,061). Distal humeral fractures increased from 5912 (2002, men/women 1559/4353) to 6493 (2017, men/women1840/4653). The total count of forearm fractures increased from 68,636 (2002, men/women 17,186/51,450) to 89,040 (2017, men/women 20,185/68,855). Women were affected in 70–75% of all cases with rising incidences among nearly every age group in female patients. Conclusion Total count of nearly every evaluated fracture increased. Also, incidences increased especially in the older female age groups. Fracture development already seems to reflect demographic changes in Germany.

Abstract
Media portrayals of a loneliness "epidemic" are premised on an increase in the proportion of people living alone and decreases in rates of civic engagement and religious affiliation over recent decades. However, loneliness is a subjective perception that does not correspond perfectly with objective social circumstances. In this study, we examined whether perceived loneliness is greater among the Baby Boomers-individuals born 1948-1965-relative to those born 1920-1947 and whether older adults have become lonelier over the past decade (2005-2016). We used data from the National Social Life, Health and Aging Project and from the Health and Retirement Study collected during 2005-2016 to estimate differences in loneliness associated with age, birth year, and survey time point. Overall, loneliness decreased with age through the early 70s, after which it increased. We found no evidence that loneliness is substantially higher among the Baby Boomers or that it has increased over the past decade. Loneliness is, however, associated with poor health, living alone or without a spouse-partner, and having fewer close family and friends, which together accounted for the overall increase in loneliness after age 75. Although these data do not support the idea that older adults are becoming lonelier, the actual number of lonely individuals may increase as the Baby Boomers age into their 80s and beyond. Our results suggest that attention to social factors and improving health may help to mitigate this. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Abstract
Background: Untreated overt hypo- and hyperthyroidism can lead to detrimental effects on muscle tissue and physical performance, but it is still unclear whether subclinical hypo- or hyperthyroidism has clinically relevant effects on muscle function and physical performance. The objective of this study was to determine associations of thyrotropin (TSH) with grip strength and physical performance. Methods: A sample of 6196 participants from the Study of Health in Pomerania and the Berlin Aging Study II was included in this cross-sectional analysis. Handgrip strength was measured with a hand-held dynamometer and physical performance was assessed with the timed up and go (TUG) test. Results: Serum TSH levels were significantly inversely associated with handgrip strength (β -0.11; [95% confidence interval, CI, -0.18 to -0.03]; p < 0.05) in multivariable linear regression. Individuals with high (β -1.06; [95% CI -1.86 to -0.26]; p < 0.05) or low (β -0.99; [95% CI -1.70 to -0.28]; p < 0.05) serum TSH levels had a significantly lower handgrip strength than individuals with serum TSH levels within the reference range. There was no association between TSH and the TUG time. Age showed a significant influence on the association of TSH with grip strength and TUG time. Conclusions: Even mild disturbances of thyroid function might lead to a relevant decline in grip strength, particularly in young and middle-aged subjects. Mild subclinical hypothyroidism might not be that unfavorable with regard to physical function in terms of handgrip strength at older age. Further studies are needed to clarify causal relationships.

Assessment of the American Heart Association's "Life's simple 7" score in French-speaking adults from Québec. Nutr Metab Cardiovasc Dis 2019; 29:684-691. [PMID: 31078363 DOI: 10.1016/j.numecd.2019.03.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2018] [Revised: 02/15/2019] [Accepted: 03/11/2019] [Indexed: 11/25/2022]
Abstract
BACKGROUND AND AIMS The "Life's Simple 7" (LS7) metrics were developed by the American Heart Association (AHA) to assess and promote cardiovascular health in the American population. The purpose of this study was to assess the overall cardiovascular health of French-speaking adults from the Province of Quebec using the LS7 score. METHODS AND RESULTS A total of 777 age and sex-representative participants of five different administrative regions in the Province of Quebec (387 men and 390 women; mean age ± SEM: 41.9 ± 0.1 years) were included in these analyses. Metrics of the LS7 score (smoking, physical activity, diet, body mass index, blood pressure, fasting total cholesterol and blood glucose) were analysed to generate a final score ranging from 0 to 7. Only 0.5% of participants met all criteria for ideal cardiovascular health. The diet metric showed the lowest prevalence of "ideal" scores (4.8%) whereas not smoking was the metric with the highest prevalence (88.1%). Women had a higher LS7 score than men, while age and education level (negative and positive association, respectively; p < 0.0001) were also associated with the LS7 score. CONCLUSION Consistent with studies conducted among other populations, very few French-speaking adults from the Province of Quebec achieve an ideal cardiovascular health. These data indicate that further public health efforts aimed at promoting the LS7 metrics, focusing primarily on diet, are urgently needed. Specific groups, including older adults and those with lower levels of education, should be targeted when developing cardiovascular health promotion interventions.
