Associations of Thyroid-Stimulating Hormone and Free Thyroxine Concentrations with Health and Life Satisfaction in Elderly Adults

ObjectiveTo analyze associations between thyroid-stimulating hormone (TSH) and free thyroxine (FT₄) concentrations and life satisfaction, symptoms, self-rated health, and common neuropsychiatric diseases (depression or dementia) in a community-dwelling elderly population to provide evidence whether to decrease the upper reference limit for TSH or the optimal TSH target in levothyroxine treatment in older adults.MethodsIn this cross-sectional study, we determined TSH and FT₄ concentrations in a thyroid disease-free population of 502 men (median age, 71 years) and 584 women (median age, 73 years) and in a patient group of 49 women (median age, 75 years) with primary hypothyroidism who were stable users of thyroxine treatment. Life satisfaction, self-rated health, depression, and dementia were assessed with Specific questions and with tools such as the Self-report Depression Scale and the Mini-Mental State Examination. Independent variables were dichotomized, and associations of these variables with TSH and FT₄ levels were assessed in the thyroid disease-free population. Levels of TSH and FT₄ in thyroid disease-free women and in women treated with thyroxine were also compared.ResultsAfter age adjustment, there were no associations between TSH levels and self-rated health, life satisfaction, or most symptoms in the thyroid disease-free population. No associations were found between diagnosed depression or Mini-Mental State Examination results and levels of TSH and FT₄. Dementia was associated with higher FT₄ concentration in men. Although women treated with thyroxine had TSH levels that were higher than thyroid disease-free women, there were no statistically significant differences in independent variables between these 2 groups.ConclusionOur results do not support the need to decrease the upper reference limit for TSH or to lower the optimal TSH target in levothyroxine treatment in older adults, as recommended in recent guidelines.

Influence of manganese exposure on cognitive function,plasma APP and Aβ levels in older men

BackgroundElevated manganese (Mn) exposure impairs cognition in adults and children, but the association between Mn and cognitive function in elderly people is unclear. Previous studies have linked Mn neurotoxicity in AD to Aβ-dependent mechanisms. However, the association between Mn and plasma APP and Aβ in the general elderly population remains unknown. This study aimed to investigate the association between Mn exposure and cognitive function, plasma APP and plasma Aβ in older adults.MethodsCognitive abilities in 375 men aged 60 and older in Guangxi, China were assessed using the Mini-Mental State Examination (MMSE) and cognitive impairment were identified using education-stratified cut-off points of MMSE scores. Urinary Mn levels and plasma APP, and Aβ levels were measured using ICP-MS and ELISA, respectively.ResultsA total of 109 (29.07 %) older men were identified as having cognitive impairment. The median urinary Mn level was 0.22 μg/g creatinine. Urinary Mn levels were negatively correlated with MMSE scores (β = −1.35, 95 % CI: −2.65 to −0.06; p = 0.041). In addition, higher concentrations of urinary manganese were associated with a greater risk of cognitive impairment (OR = 2.03, 95 % CI: 1.14–3.59; comparing the highest and lowest manganese; p = 0.025). Moreover, plasma APP levels were inversely associated with urinary Mn levels (r = −0.123, p = 0.020), and positively associated with MMSE scores (r = 0.158, p = 0.002). Surprisingly, no correlations were observed between plasma Aβ42, Aβ40, Aβ40/Aβ42, or Aβ42/Aβ40 and urinary Mn levels and MMSE scores.ConclusionThese results suggested that Mn exposure is negatively associated with older men’s cognition and plasma APP levels, but not plasma Aβ levels.     

Evaluación funcional y cognitiva en una población urbana de mayores de 89 años. Estudio NonaSantFeliu

Introductionthe increase in life expectancy should be characterized by an increase in disability-free life. We assessed functional and cognitive capacity in an urban population older than 89 years, as well as possible gender variations.Material and methodsthe NonaSantFeliu study is a longitudinal, observational, population-based study. We present the first crosssectional survey of 186 inhabitants older than 89 years in a city. Sociodemographic data were gathered. We assessed basic activities of daily living with the Barthel Index (BI), instrumental activities with the Lawton Index (LI), cognitive status with the Mini-Mental State Examination (MMSE) and comorbidity with the Charlson Index (CI).Resultsof 186 examined nonagenarians, 143 (76.5%) were women. The mean age SD was 93.1 ± 3.1 years. One-hundred forty nine (80.2%) were widowed and 26% were institutionalized. The mean BI was 60.8 ± 30; 56% were functionally independent or had slight dependence. The mean LI was 2.1 ± 2.8. The mean MMSE score was 21 ± 11; 56% had an MMSE score higher than 23. The mean CI was 1.4 ± 1.7. No significant differences were found by gender.Conclusionsdespite their advanced age, most of the nonagenarians showed mild functional and cognitive impairment with low comorbidity. No significant differences were observed by gender. Future studies should help to detect nonagenarians at high risk of rapid impairment to allow early initiation of interventions to delay the development of further incapacity.     

Relationship between physiological tremor and cognitive function in physically active older women

[Purpose]This study aimed to compare the physiological tremor, grip strength, and cognitive function of sedentary and physically active older adults.[Methods]Twenty-four older adults aged ≥65 years participated in this study and were divided into the sedentary (76.5±4.4 years, n=12) and physically active (73.5±3.3 years, n=12) groups. Each group completed the Mini-Mental State Examination (MMSE) for cognitive function assessment. Physiological tremor was measured using an accelerometer for both hands at rest and the left/right hand with a 1,000 g dumbbell on the palm in neutral positions and the elbow flexed at 90°. Physical fitness was measured by grip strength and completion of the Short Physical Performance Battery (SPPB) and the 6-min walk test.[Results]The physically active group showed a significantly lower level of physiological tremor in both hands at rest and the left/right hand with a 1,000 g dumbbell on the palm (P<0.05) than that in the sedentary group. For cognitive function, the physically active group showed significantly higher scores than those in the sedentary group (P<0.001). No significant correlation was found between cognitive function and left/right grip strength (left: r = 0.117, P = 0.585; right: r = 0.230, P = 0.279), physiological tremor in both hands at rest (left: r = -0.524, P < 0.001; right: r = -0.508, P < 0.05), and the left/right hand with a 1,000 g dumbbell on the palm (left: r = -0.505, P < 0.05; right: r = -0.458, P < 0.05).[Conclusion]Physiological tremor of the hands has the potential to be a useful predictor of cognitive function in older adults.     

Health-related quality of life and weight loss among overweight and obese U.S. adults, 2001 to 2002

Objective: To examine the prevalence and association of health‐related quality of life (HRQOL) with trying to lose weight and with weight loss practices (eating fewer calories, physical activity, and both) among overweight and obese U.S. adults ≥ 20 years of age. Research Methods and Procedures: This study used data from the 2001 to 2002 National Health and Nutrition Examination Survey, a continuous annual survey of the civilian non‐institutionalized U.S. population. This analysis included those ≥ 20 years of age with BMI ≥ 25 (n = 2578) who responded to four standard HRQOL measures that assessed general health status and recent physical health, mental health, and activity limitation. Results: Among obese men, but not women, there were significant increasing linear trends in the adjusted prevalence of trying to lose weight as physically unhealthy and activity limitation days increased. Regardless of BMI or HRQOL, reducing calories was a common weight loss practice (66% to 86%). Except for recent activity limitation, respondents with BMI ≥ 35 did not generally differ by HRQOL level in the attainment of recommended physical activity either alone or in combination with reduced calories, whereas those in the BMI 25 to 34.9 groups often differed significantly by HRQOL level. Specifically, increased unhealthy or activity limitation days were associated with reduced prevalence of attained physical activity. Discussion: Our findings indicate an association between trying to lose weight and a greater number of unhealthy days reported by obese men, suggesting that these men may be influenced by traditional clinical weight‐loss counseling that is prompted by weight and comorbidity, whereas women had a high prevalence of trying to lose weight irrespective of weight and HRQOL. Assessment of HRQOL, especially measures that evaluate physical domains, could provide subjective information to assist with weight counseling.     

Perceived sleep quality among edentulous elders

doi: 10.1111/j.1741‐2358.2010.00426.x Perceived sleep quality among edentulous elders Background: Anatomical changes associated with edentulism are thought to disturb seniors’ sleep. Objectives: (1) To determine sleep quality and daytime sleepiness of edentulous elders. (2) To examine the association between oral health‐related quality of life and sleep quality. Methods: Data were collected at a 1‐year follow‐up from 173 healthy edentulous elders who had participated in a randomised controlled trial and randomly received two types of mandibular prosthesis. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI, range 0–21), with higher scores indicating poorer sleep quality. The Epworth Sleepiness Scale (ESS) was used to measure the level of perceived daytime sleepiness, and scores ≥10 indicated sleepiness. Results: The mean global PSQI and ESS scores were 4.7 ± 3.5 and 5.3 ± 3.9. There were no differences in sleep quality or sleepiness between those who wore their dentures at night and those who did not. Elders with frequent denture problems were sleepier during the day than those with fewer problems (p = 0.0034). General health (p = 0.02) and oral health‐related quality of life (p = 0.001) are significant predictors of sleep quality. Conclusion: Healthy edentulous elders, independent of nocturnal wearing of their prosthesis, are good sleepers. Maintaining high oral health quality of life could contribute to better sleep.     

Mild Cognitive Impairment: Vascular Risk Factors in Community Elderly in Four Cities of Hebei Province,China

BackgroundEvidence has demonstrated that vascular risk factors (VRFs) contribute to mild cognitive impairment (MCI) in the elderly population. Because of the race and different diagnosis standard, there is still no definitive conclusions.ObjectiveTo estimate the VRFs and potential protective factors for MCI in elderly population living in the community in North China.MethodsA total of 3136 participants entered the study. They were screened for hypertension, coronary heart disease (CHD), and cerebrovascular disease (CVD). Cognitive function was assessed with Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). The diagnosis of MCI was made according to Petersen’s criteria. We investigated the relationship between vascular risk factors, potential protective factors and MCI.ResultsA total of 2511 (80%) participant belonged to normal group and 625 (20%) participants showed MCI. Multiple logistic regression analysis demonstrated that stroke and diabetes, but not hypertension or CHD was associated with MCI. Besides, exercise habit could lower the risk of MCI.ConclusionsVascular Risk Factors, including stroke and diabetes, rather than hypertension and CHD are independent risk factors of MCI. Involvement in physical activities seems to reduce the risk of MCI.     

Quality of life of patients after stroke in county Osijek-Baranya

The purpose of this prospective study was to determine quality of life of patients after stroke in Osijek-Baranya County. The research included 161 patients (82 men and 79 women) who had their first acute stroke and were treated at Department of Neurology, Osijek University Hospital Center The Barthel Index (BI) was used to assess functional deficiency and SS-QOL (Stroke-Specific Quality of Life) questionnaire was used for self-evaluation of patients' physical and mental health. The first assessment was carried out in the acute phase of the disease, and control assessments 30, 90 and 180 days after the stroke. Mean Barthel Index score was higher at every successive measurement (55, 80, 95, 95). All BI items were statistically significant (Friedman, p < 0.001) apart from dressing and bowel control. BI score indicated greater dependence in women in all assessments except for those taken 90 days after onset of symptoms (chi2-test, p = 0.111). Mean values of SS-QOL for physical health were: 105.2, 98.3, 105.7, 117.5 and for mental health: 64.24, 57.9, 64.3, 68.1. Statistically significant difference was present in men, both for physical health (Friedman p = 0.009) and total SS-QOL (Friedman p = 0.014), while in women there was no statistically significant difference between the measurements (Friedman p = 0.719). The research showed that stroke has significant influence on basic and specific daily life activities and interferes with the quality of life of stroke patients. Women have lower level of independence. Patients who live with their families make better evaluation of their physical and mental health.     

衰弱对老年类风湿关节炎患者焦虑抑郁、免疫功能和认知功能的影响

摘要 目的：观察衰弱对老年类风湿关节炎（RA）患者焦虑抑郁、免疫功能和认知功能的影响。方法：选取2019年1月至2021年12月我院收治的138例RA患者,根据是否发生衰弱将患者分为衰弱组和非衰弱组。对比衰弱组、非衰弱组的焦虑抑郁评分、免疫功能相关指标和认知功能评分变化情况。结果：138例老年RA患者有91例存在衰弱,47例无衰弱。根据是否衰弱将患者分为衰弱组（n=91）和非衰弱组（n=47）。衰弱组的焦虑自评量表（SAS）、抑郁自评量表（SDS）评分高于非衰弱组（P<0.05）。衰弱组的CD3⁺、CD4⁺、CD4⁺/CD8⁺低于非衰弱组,CD8+高于非衰弱组（P<0.05）。衰弱组的简易精神状态评估量表（MMSE）评分、蒙特利尔认知评估量表（MoCA）评分低于非衰弱组（P<0.05）。结论：衰弱可以增加老年RA患者的焦虑抑郁程度,还可导致免疫功能和认知功能下降。

摘要 目的：探讨记忆训练联合电针疗法对全脑放疗患者认知功能、健康相关生命质量和颅脑磁共振灌注成像参数的影响。方法：选择江南大学附属医院2020年3月～2022年1月期间收治的全脑放疗患者94例,根据随机数字表法分为研究组（常规干预、记忆训练联合电针疗法）和对照组（常规干预）,各为47例。对比两组认知功能、健康相关生命质量和颅脑磁共振灌注成像参数的变化。结果：治疗1周、2周、3周、4周后,两组蒙特利尔认知功能检查量表（MoCA）和简易精神状态量表（MMSE）评分均较治疗前逐渐下降,但研究组各时间点MoCA、MMSE评分高于对照组（P<0.05）。治疗4周后,两组健康相关生命质量量表（HRQoL）各维度评分及总分均较治疗前升高,且研究组上述评分均高于对照组（P<0.05）。治疗4周后,两组颅脑平均脑血容量（CBV）值和平均脑血流量（CBF）值均较治疗前下降,但研究组上述值高于对照组（P<0.05）。结论：记忆训练联合电针疗法可减缓全脑放疗后导致的认知功能损害,并提升患者的健康相关生命质量,可能与调节脑血容量、脑血流量有关。     

Instrumental and Non-Instrumental Evaluation of 4-Meter Walking Speed in Older Individuals

BackgroundManual measurement of 4-meter gait speed by a stopwatch is the gold standard test for functional assessment in older adults. However, the accuracy of this technique may be biased by several factors, including intra- and inter-operator variability. Instrumental techniques of measurement using accelerometers may have a higher accuracy. Studies addressing the concordance between these two techniques are missing. The aim of the present community-based observational study was to compare manual and instrumental measurements of 4-meter gait speed in older individuals and to assess their relationship with other indicators of physical performance.MethodsOne-hundred seventy-two (69 men, 103 women) non-disabled community-dwellers aged ≥65 years were enrolled. They underwent a comprehensive geriatric assessment including physical function by Short Physical Performance Battery (SPPB), hand grip strength, and 6-minute walking test (6MWT). Timed usual walking speed on a 4-meter course was assessed by using both a stopwatch (4-meter manual measurement, 4-MM) and a tri-axial accelerometer (4-meter automatic measurement, 4-MA). Correlations between these performance measures were evaluated separately in men and women by partial correlation coefficients.ResultsIn both genders, 4-MA was associated with 4-MM (men r = 0.62, p<0.001; women r = 0.73, p<0.001), handgrip strength (men r = 0.40, p = 0.005; women r = 0.29, p = 0.001) and 6MWT (men r = 0.50, p = 0.0004; women r = 0.22, p = 0.048). 4-MM was associated with handgrip strength and 6MWT in both men and women. Considering gait speed <0.6 m/s as diagnostic of dismobility syndrome, the two methods of assessment disagreed, with a different categorization of subjects, in 19% of men and 23% of women. The use of accelerometer resulted in 29 (13 M, 16 F) additional diagnoses of dismobility, compared with the 4-MM.ConclusionsIn an older population, the concordance of gait speeds manually or instrumentally assessed is not optimal. The results suggest that manual measures might lead to misclassification of a substantial number of subjects. However, longitudinal studies using standardized and validated procedures aimed at the comparison of different techniques are needed before recommending the use of accelerometers in comprehensive geriatric assessment.     

Changes in Disability,Physical/Mental Health States and Quality of Life during an 8-Week Multimodal Physiotherapy Programme in Patients with Chronic Non-Specific Neck Pain: A Prospective Cohort Study

AimThe aim of this study was to analyse the effect of an 8-week multimodal physiotherapy programme (MPP), integrating physical land-based therapeutic exercise (TE), adapted swimming and health education, as a treatment for patients with chronic non-specific neck pain (CNSNP), on disability, general health/mental states and quality of life.Methods175 CNSNP patients from a community-based centre were recruited to participate in this prospective study. Intervention: 60-minute session (30 minutes of land-based exercise dedicated to improving mobility, motor control, resistance and strengthening of the neck muscles, and 30 minutes of adapted swimming with aerobic exercise keeping a neutral neck position using a snorkel). Health education was provided using a decalogue on CNSNP and constant repetition of brief advice by the physiotherapist during the supervision of the exercises in each session. Study outcomes: primary: disability (Neck Disability Index); secondary: physical and mental health states and quality of life of patients (SF-12 and EuroQoL-5D respectively). Differences between baseline data and that at the 8-week follow-up were calculated for all outcome variables.ResultsDisability showed a significant improvement of 24.6% from a mean (SD) of 28.2 (13.08) at baseline to 16.88 (11.62) at the end of the 8-week intervention. All secondary outcome variables were observed to show significant, clinically relevant improvements with increase ranges between 13.0% and 16.3% from a mean of 0.70 (0.2) at baseline to 0.83 (0.2), for EuroQoL-5D, and from a mean of 40.6 (12.7) at baseline to 56.9 (9.5), for mental health state, at the end of the 8-week intervention.ConclusionAfter 8 weeks of a MPP that integrated land-based physical TE, health education and adapted swimming, clinically-relevant and statistically-significant improvements were observed for disability, physical and mental health states and quality of life in patients who suffer CNSNP. The clinical efficacy requires verification using a randomised controlled study design.

Depression Affects the Scores of All Facets of the WHOQOL-BREF and May Mediate the Effects of Physical Disability among Community-Dwelling Older Adults

Background

Geriatric depression is associated with the overall quality of life (QOL). However, how depressive symptoms affect the different domains and facets of QOL in older adults, and whether depressive symptoms mediate the relationship between physical disability and QOL in older adults are unclear.

Methods

A total of 490 ambulatory community-dwelling older adults aged 65 years or above were interviewed using the brief version of the World Health Organisation Quality of Life instrument (WHOQOL-BREF), the Modified Barthel Index (MBI), the 15-item Geriatric Depression Scale (GDS-15), and the Mini-Mental State Examination (MMSE). Sequential models for multiple linear regressions were analysed to determine if the MBI, GDS-15 and MMSE scores predict the WHOQOL-BREF scores. The potential mediation effects of depression (as determined by the GDS-15) on the relationship between MBI and WHOQOL-BREF were also analysed.

Results

The GDS-15 score was predictive of the scores of the four domains and all 26 facets of the WHOQOL-BREF. The significant predictive effects of the MBI score on 15 of the 26 facets of the WHOQOL-BREF were reduced to three after the adjustment for the GDS-15 score. Depression (as assessed by the GDS-15) is a mediator of the relationship between MBI and the physical, psychological and environmental domains of the WHOQOL-BREF.

Conclusions

Depression (assessed by the GDS-15) may affect the scores of every domain and all facets of the WHOQOL-BREF in the elderly. Furthermore, it may mediate the relationship between the MBI and on QOL scores. We recommend taking depressive symptoms into consideration when measuring community-dwelling older adults’ QOL and providing active ageing programs.

摘要 目的：探讨肺癌患者心理弹性的影响因素,分析肺癌患者心理弹性与社会支持和生活质量的关系。方法：选取2018年6月至2019年12月期间我院收治的173例肺癌患者（肺癌组）和同期于我院进行体检的116例健康者（对照组）,分别采用心理弹性量表（CD-RISC）、社会支持评定量表（SSRS）、健康状况调查简表（SF-36）评估所有受试者心理弹性、社会支持、生活质量。收集患者临床资料,分析肺癌患者心理弹性的影响因素。相关性分析采用Pearson检验。结果：肺癌组CD-RISC、SSRS、SF-36评分均低于对照组（P＜0.05）。不同年龄、性别、教育程度、性格特征、SSRS评分、治疗阶段、复发情况、转移情况患者之间CD-RISC评分比较差异显著（P＜0.05）。多重线性回归分析结果显示性别、教育程度、性格特征、SSRS评分、治疗阶段、复发、转移均为肺癌患者心理弹性的影响因素（P＜0.05）。Pearson相关分析结果显示肺癌患者CD-RISC评分与SSRS、SF-36评分均呈正相关（r=0.567、0.617,P=0.047、0.346）。结论：肺癌患者心理弹性较正常人降低,性别、教育程度、性格特征、SSRS评分、治疗阶段、复发、转移是影响肺癌患者心理弹性的主要因素。肺癌患者心理弹性与社会支持、生活质量均有关。     

Effects of Depressive Symptoms and Family Satisfaction on Health Related Quality of Life: The Hong Kong FAMILY Study

Objective

To examine the effect of depressive symptoms and satisfaction with family support (FS) on physical and mental Health Related Quality of Life (HRQoL).

Methods

Data were obtained from the Hong Kong FAMILY Project baseline survey in 2009–2011, which included 16,039 community residents (age ≥20). The FS was measured using the Family Adaptation, Partnership, Growth, Affection, Resolve (APGAR, range 0–10) Questionnaire. HRQoL were assessed using the SF-12 version 2. Depressive symptoms were recorded using the Patient Health Questionnaire-9 (PHQ-9). Demographic and lifestyle variables, stressful life events, perceived neighborhood cohesion were also assessed.

Results

In a multilevel regression model, socio-demographic and behavioral variables explained 21% and 19% of the variance in physical and mental HRQoL. The presence of depressive symptoms (PHQ-9 score ≥10, standardized coefficients, β of −1.73) and high FS (APGAR score 7–10, 1.15) were associated with mental HRQoL, after adjustment for age, education, household monthly income, drinking status, physical activity, chronic conditions, life stress and neighborhood cohesion. Not FS but the presence of depressive symptoms (β of −0.88) was associated with physical HRQoL. The presence of depressive symptoms in women than men were more associated with a poorer physical HRQoL (p<0.01) while depressive symptoms in men were associated with a decrease in mental HRQoL (p<0.001). The interaction between FS and depressive symptoms was nonsignificant in relation to HRQoL. Among those with depressive symptoms, high FS was associated with a better mental HRQoL (41.1 vs. 37.9, p<0.001) in women but not contribute to variance in men.

Conclusions

Higher FS and presence of depressive symptoms were significantly associated with HRQoL in general population in Hong Kong. Among those with depressive symptoms, high FS was associated with a favorable mental HRQoL in women but not men.     

Prevalence of Mental Illness among Homeless People in Hong Kong

MetholodogyThis study examined the prevalence and correlates of mental illness in homeless people in Hong Kong and explored the barriers preventing their access to health care. Ninety-seven Cantonese-speaking Chinese who were homeless during the study period were selected at random from the records of the three organisations serving the homeless population. The response rate was 69%. Seventeen subjects could not give valid consent due to their poor mental state, so their responses were excluded from the data analysis. A psychiatrist administered the Structured Clinical Interview for DSM-IV Axis-I disorders (SCID-I) and the Mini -Mental State Examination. Consensus diagnoses for subjects who could not complete the SCID-I were established by three independent psychiatrists.FindingsThe point prevalence of mental illness was 56%. Seventy-one percent of the subjects had a lifetime history of mental illness, 30% had a mood disorder, 25% had an alcohol use disorder, 25% had a substance use disorder, 10% had a psychotic disorder, 10% had an anxiety disorder and 6% had dementia. Forty-one percent of the subjects with mental illness had undergone a previous psychiatric assessment. Only 13% of the subjects with mental illness were receiving psychiatric care at the time of interview. The prevalence of psychotic disorders, dementia and the rate of under treatment are hugely underestimated, as a significant proportion (18%) of the subjects initially selected were too ill to give consent to join the study.ConclusionThe low treatment rate and the presence of this severely ill and unreached group of homeless people reflect the fact that the current mode of service delivery is failing to support the most severely ill homeless individuals.     

Polymorphisms of the DNA repair gene EXO1 modulate cognitive aging in old adults in a Taiwanese population

Evidence indicates that the age-related neuropathological mechanisms associated with DNA repair genes may contribute to cognitive aging and Alzheimer’s disease. In this study, we hypothesize that single nucleotide polymorphisms (SNPs) within 155 DNA repair genes may be linked to cognitive aging independently and/or through complex interactions in an older Taiwanese population. A total of 3,730 Taiwanese subjects aged over 60 years from the Taiwan Biobank were analyzed. Mini-Mental State Examination (MMSE) was administered to all subjects, and MMSE scores were used to measure cognitive functions. Our data showed that out of 1,652 SNPs, the rs1776181 (P = 1.47 × 10⁻⁵), rs1776177 (P = 8.42 × 10^-7), rs1635510 (P = 7.97 × 10^-6), and rs2526698 (P = 7.06 × 10^-6) SNPs in the EXO1 gene were associated with cognitive aging. The association with these SNP remained significant after performing Bonferroni correction. Additionally, we found that interactions between the EXO1 and RAD51C genes influenced cognitive aging (P = 0.002). Finally, we pinpointed the influence of interactions between EXO1 and physical activity (P < 0.001) as well as between DCLRE1C and physical activity (P < 0.001). Our study indicated that DNA repair genes may contribute to susceptibility in cognitive aging independently as well as through gene-gene and gene-physical interactions.     

Health-Related Quality of Life of Latin-American Immigrants and Spanish-Born Attended in Spanish Primary Health Care: Socio-Demographic and Psychosocial Factors

Background

This study compares the health-related quality of life of Spanish-born and Latin American-born individuals settled in Spain. Socio-demographic and psychosocial factors associated with health-related quality of life are analyzed.

Methods

A cross-sectional Primary Health Care multi center-based study of Latin American-born (n = 691) and Spanish-born (n = 903) outpatients from 15 Primary Health Care Centers (Madrid, Spain). The Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) was used to assess health-related quality of life. Socio-demographic, psychosocial, and specific migration data were also collected.

Results

Compared to Spanish-born participants, Latin American-born participants reported higher health-related quality of life in the physical functioning and vitality dimensions. Across the entire sample, Latin American-born participants, younger participants, men and those with high social support reported significantly higher levels of physical health. Men with higher social support and a higher income reported significantly higher mental health. When stratified by gender, data show that for men physical health was only positively associated with younger age. For women, in addition to age, social support and marital status were significantly related. Both men and women with higher social support and income had significantly better mental health. Finally, for immigrants, the physical and mental health components of health-related quality of life were not found to be significantly associated with any of the pre-migration factors or conditions of migration. Only the variable “exposure to political violence” was significantly associated with the mental health component (p = 0.014).

Conclusions

The key factors to understanding HRQoL among Latin American-born immigrants settled in Spain are age, sex and social support. Therefore, strategies to maintain optimal health outcomes in these immigrant communities should include public policies on social inclusion in the host society and focus on improving social support networks in order to foster and maintain the health and HRQoL of this group.     

Poor physical fitness is independently associated with mild cognitive impairment in elderly Koreans

The purpose of this study was to investigate the association between physical fitness and mild cognitive impairment (MCI) in elderly Koreans. This was a cross-sectional study that involved 134 men and 299 women aged 65 to 88 years. Six senior fitness tests were used as independent variables: 30 s chair stand for lower body strength, arm curl for upper body strength, chair-sit-and-reach for lower body flexibility, back scratch for upper body flexibility, 8-ft up-and-go for agility/dynamic balance, and 2-min walk for aerobic endurance. Global cognitive function was assessed using the Korean version of the Mini-Mental State Examination (MMSE). Potential covariates such as age, education levels, blood lipids, and insulin resistance (IR) markers were also assessed. Compared to individuals without MMSE-based MCI, individuals with MMSE-based MCI had poor physical fitness based on the senior fitness test (SFT). There were significant positive trends observed for education level (p=0.001) and MMSE score (p<0.001) across incremental levels of physical fitness in this study population. Individuals with moderate (OR=0.341, p=0.006) and high (OR=0.271, p=0.007) physical fitness based on a composite score of the SFT measures were less likely to have MMSE-based MCI than individuals with low physical fitness (referent, OR=1). The strength of the association between moderate (OR=0.377, p=0.038) or high (OR=0.282, p=0.050) physical fitness and MMSE-based MCI was somewhat attenuated but remained statistically significant even after adjustment for the measured compounding factors. We found that poor physical fitness was independently associated with MMSE-based MCI in elderly Koreans.
