The association between self-rated health and high-sensitivity C-reactive protein level: a cross-sectional and 5-year longitudinal study

Patient global assessment and inflammatory markers in patients with idiopathic inflammatory myopathies - A longitudinal study

AIM

To explore if patient global assessment (PGA) is associated with inflammation over time and if associations are explained by other measures of disease activity and function in patients with idiopathic inflammatory myopathies (IIM).

METHODS

PGA and systemic inflammatory markers prospectively collected over five years were retrieved from the International MyoNet registry for 1200 patients with IIM. Associations between PGA, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and creatine kinase (CK) were analyzed using mixed models. Mediation analysis was used to test if the association between PGA and inflammatory markers during the first year of observation could be explained by measures of disease activity and function.

RESULTS

PGA improved, and inflammatory markers decreased during the first year of observation. In the mixed models, high levels of inflammatory markers were associated with worse PGA in both men and women across time points during five years of observation. In men, but not in women, the association between elevated ESR, CRP and poorer PGA was explained by measures of function and disease activity. With a few exceptions, the association between improved PGA and reduced inflammatory markers was partially mediated by improvements in all measures of function and disease activity.

CONCLUSION

Increased levels of systemic inflammation are associated with poorer PGA in patients with IIM. In addition to known benefits of lowered inflammation, these findings emphasize the need to reduce systemic inflammation to improve subjective health in patients with IIM. Furthermore, the results demonstrate the importance of incorporating PGA as an outcome measure in clinical practice and clinical trials.

Association of daily physical activity and leisure-time exercise with dysphagia risk in community-dwelling older adults: a cross-sectional study

This study aimed to clarify the association of daily physical activity and leisure-time exercise with the risk of dysphagia in community-dwelling Japanese older adults using a questionnaire-based survey. We analyzed 3070 participants (1657 men, 1413 women; age 66 ± 4 years [mean ± SD]) of the Shizuoka and Daiko studies within the Japanese Multi-Institutional Collaborative Cohort study. We used the Dysphagia Risk Assessment for the Community-dwelling Elderly questionnaire to assess dysphagia risk and the International Physical Activity Questionnaire to assess daily physical activity and leisure-time exercise. Logistic regression analyses were used to evaluate the independent association of the amount of physical activity and leisure-time exercise with dysphagia risk. The proportion of participants with dysphagia risk was 27.5% (n = 844) and the risk was significantly higher in women (29.8%, n = 421) than in men (25.5%, n = 423; P = 0.008). Daily physical activity was not associated with dysphagia risk. A greater amount of leisure-time exercise was associated with lower dysphagia risk (P for trend = 0.003) and individuals in the highest leisure-time exercise quartile had a significantly lower odds ratio (0.68, 95% CI 0.52-0.89) than those in the lowest quartile, even after adjusting for the covariates.

Association of the number of teeth and self-rated mastication with self-rated health in community-dwelling Japanese aged 40 years and older: the Yamagata cohort study

Self-rated health (SRH) is a predictive factor for health-related prognoses such as mortality. This study aimed to comprehensively investigate the risk factors for poor SRH in the general population of Japan, focusing on the combination of the number of teeth and self-rated mastication. Individuals aged at least 40 years in Yamagata Prefecture, Japan, were surveyed from 2017 to 2021. The participants answered a self-administered postal survey on lifestyle factors, medical history, physical and mental conditions, oral health, and dietary intake, and 6739 participants were included. Multivariate logistic regression analysis showed that individuals with less than 20 teeth and who bite tightly on one side or neither side were at a 1.422- and 1.952-fold significantly higher risk, respectively, of poor SRH than individuals with at least 20 teeth and who bite tightly on both sides. Moreover, individuals who had less than 20 teeth but could bite tightly on both sides did not have a significant risk compared to those who had at least 20 teeth and could bite tightly on both sides. Regarding individuals with more than 20 teeth, there was no difference between those who could and could not bite tightly on both sides, although the odds ratios for poor SRH tended to increase for those who could bite on one side or neither side. Our results emphasize the importance of having at least 20 teeth without periodontal disease and oral rehabilitation using a type of prosthesis for SRH, even with less than 20 teeth.

The health status: the ignored risk factor in dementia incidence. NEDICES cohort

BACKGROUND

The causes of the dementia decrease in affluent countries are not well known but health amelioration could probably play a major role. Nevertheless, although many vascular and systemic disorders in adult life are well-known risk factors (RF) for dementia and Alzheimer disease (AD), health status is rarely considered as a single RF.

AIM

To analyse whether the health status and the self-perceived health (SPH) could be RF for dementia and AD and to discuss its biological basis.

METHODS

We analysed different objective health measures and SPH as RF for dementia and AD incidence in 4569 participants of the NEDICES cohort by means of Cox-regression models. The mean follow-up period was 3.2 (range: 0.03-6.6) years.

RESULTS

Ageing, low education, history of stroke, and "poor" SPH were the main RF for dementia and AD incidence, whereas physical activity was protective. "Poor" SPH had a hazard ratio = 1.66 (95% CI 1.17-2.46; p = 0.012) after controlling for different confounders.

DISCUSSION

According to data from NEDICES cohort, SPH is a better predictor of dementia and AD than other more objective health status proxies. SPH should be considered a holistic and biologically rooted indicator of health status, which can predict future development of dementia and AD in older adults.

CONCLUSIONS

Our data indicate that it is worthwhile to include the SPH status as a RF in the studies of dementia and AD incidence and to explore the effect of its improvement in the evolution of this incidence.

[Association of self-rated health with inflammatory markers among nursing home employees]

OBJECTIVES

Although self-rated health (SRH), the self-evaluation of one's own health status, has been reported to be associated with the immune status, the relationship between three different SRH measures (global, self-comparative, and age-comparative) with inflammatory markers as well as the relative strength of these associations by age are not well understood. The current study investigated the associations between SRH measures and inflammatory markers among nursing home employees.

METHODS

A sample of 120 Japanese employees at a nursing home (90 women and 30 men), aged 21-68 years (mean, 40.9 years), underwent a blood test for the measurement of inflammatory markers (interferon-γ, interleukin [IL]-4, IL-6, and tumor necrosis factor [TNF]-α, white blood cell count) and SRH during the annual health checkup. Multiple regression analysis adjusted for covariates was performed to analyze the relationship between inflammatory markers and SRH measures stratified by age, that is, aged < 40 years (younger age group) and 40 years and over (older age group).

RESULTS

Among the participants aged 40 years and over, poor global SRH was significantly associated with an increase in IL-6, while poor age-comparative SRH was significantly associated with an increase in TNF-α among participants aged < 40 years in the fully adjusted model controlling for potential confounders. Age-comparative SRH was also significantly associated with an increase in IL-6 among all participants. Self-comparative SRH was not significantly associated with inflammatory markers.

CONCLUSIONS

Our results suggest that three SRH measures are not equivalently associated with inflammatory markers, especially when the analyses were performed separately for the younger and older populations. This implies that not only differences in forms of SRH but also in age modify the relationship between SRH and inflammatory markers.

Physical and Psychological Factors Contributing to Incidental Falls in Older Adults Who Perceive Themselves as Unhealthy: A Cross-Sectional Study

Falls have become one of the common causes of morbidity and mortality in the elderly. Advanced age is a strong predictor of falls. Additionally, those who perceive themselves as unhealthy are more likely to suffer from incidental falls in accordance with aging. We aimed to compare individual, physical, and psychological factors between older adults with and without a fall history. Then, we tried to identify physical and psychological variables associated with falls by controlling for individual characteristics. We analyzed public data from the 2017 National Survey of Older Persons in South Korea. Seniors aged 65 years and over who considered themselves in poor health status were eligible. A total of 2765 women and 1280 men (n = 4045) were enrolled, and 940 adults suffered a fall within a year (the average number of falls was 2.5). We applied individual variable-adjusted models and discovered that hearing discomfort (odds ratio (OR) 1.30, 95% confidence interval (CI) 1.09–1.55), limited activities of daily living (ADL) (OR 1.40, 95% CI 1.13–1.74), limited instrumental activities of daily living (IADL) (OR 1.34, 95% CI 1.13–1.61), and depression (OR 1.44, 95% CI 1.23–1.69) significantly increased risk for falls on multivariate logistic regression. Our findings suggest that hearing discomfort, limited ADL/IADL, and depression need to be addressed observantly to prevent falls in the elderly who consider themselves unhealthy.

The association between self-compassion and self-rated health in 26 samples

Background

Although there is growing evidence of the relevance of self-compassion for understanding health outcomes, few studies have examined self-compassion in relation to self-reported physical health status, also known as self-rated health (SRH). This study addressed this gap by examining the associations between self-compassion and SRH across multiple samples and after accounting for the contributions of positive and negative affect.

Methods

Data from 26 samples (total N = 6127), comprised of 6 university student, 16 community adult, and 4 chronic illness samples, were included in the current analyses. Participants in each sample completed a survey including measures of self-compassion and SRH. Thirteen samples also completed a measure of positive and negative affect. The associations between self-compassion and SRH were statistically meta-analysed. Moderator analyses were conducted to test whether the associations varied as a function of sample type, age or participant sex. Semipartial correlations were calculated controlling for positive and negative affect in 13 samples and meta-analysed.

Results

Findings indicated that self-compassion was significantly associated with higher SRH across the 26 samples (r_avg = .25; CI: .22, .28). The associations did not however vary significantly across sample types, or as a function of participant sex or age. The meta-analyses of the adjusted effects found that self-compassion remained significantly associated with higher SRH after accounting the contributions of positive (sr_avg = .11; CI: .07, .15) and negative (sr_avg = .25; CI: .06, .15) affect.

Conclusions

The current study demonstrated that self-compassion is robustly associated with higher SRH across 26 samples and that this association remained significant after adjusting for the influence of positive and negative affect in 13 samples. Further longitudinal and experimental research is needed to verify the causal direction between self-compassion and SRH suggested by theory and the current findings.

The role of education in the association between self-rated health and levels of C-reactive protein: a cross-sectional study in rural areas of China

OBJECTIVES

This study aims to examine the association between self-rated health (SRH) and levels of C-reactive protein (CRP) among adults aged 45 to 101 years old in rural areas of China, and to explore the role of education in the association.

DESIGN

Cross-sectional study.

SETTING

The study population was derived from two databases in China: Nanping project (NP) and the China Health and Retirement Longitudinal Study (CHARLS).

PARTICIPANTS

There were 646 participants from a rural area of Nanping (NP) and 8555 rural participants from a national representative sample of China (CHARLS).

METHODS

CRP was measured using a high sensitivity sandwich enzyme immunoassay in the NP and immunoturbidimetric assay in the CHARLS. SRH was assessed by SRH questionnaires and categorised into good and poor. Education was measured by the maximum years of schooling and dichotomised into illiterate and literate. Multivariate linear regression models were used to study the associations.

RESULTS

Compared to people with good SRH, those with poor SRH had higher levels of CRP in NP (β=0.16, 95% CI -0.02 to 0.34) and in CHARLS (β=0.07, 95% CI 0.02 to 0.11) after adjusting for potential confounders. Similar findings were observed in the pooled population (β=0.08, 95% CI 0.03 to 0.12), especially in men (β=0.13, 95% CI 0.06 to 0.20) and in literate people (β=0.12, 95% CI 0.06 to 0.18).

CONCLUSION

Poor SRH may be a predicator of elevated levels of CRP among middle-aged and older people in rural areas, especially in men and literate people.

Assessment of self-rated health 5 years after Roux-en-Y gastric bypass for severe obesity

Background

Patients' perceptions of health change after bariatric surgery are complex. The aim of this study was to explore whether self‐rated health (SRH), a widely used tool in public health research, might be relevant as an outcome measure after Roux‐en‐Y gastric bypass (RYGB) for severe obesity.

Methods

This was a single‐centre retrospective study of a local quality registry. SRH score was registered at baseline and 5 years after RYGB. SRH, one of the 36 items in the quality‐of‐life Short Form 36 (SF‐36®) questionnaire, is the answer to this single question: ‘In general, would you say your health is excellent (1), very good (2), good (3), fair (4) or poor (5)?’ Change in SRH was analysed in relation to change in weight, co‐morbidities and quality of life after 5 years.

Results

Of a total of 359 patients who underwent RYGB between September 2006 and February 2011, 233 (64·9 per cent) reported on SRH before and 5 years after surgery. Of these, 180 (77·3 per cent) were women, and the mean(s.d.) age was 40(9) years. Some 154 patients (66·1 per cent) reported an improvement in SRH, 60 (25·8 per cent) had no change, and SRH decreased in 19 patients (8·2 per cent). SRH in improvers was related to better scores in all SF‐36® domains, whereas SRH in non‐improvers was related to unchanged or worsened scores in all SF‐36® domains except physical function.

Conclusion

Two‐thirds of patients reported improved SRH 5 years after RYGB for severe obesity. In view of its simplicity, SRH may be an easy‐to‐use outcome measure in bariatric surgery.
