Body awareness disturbances in patients with low back pain: a systematic review.

BACKGROUND: The pain-neuroscience literature has recently emphasized body perception or awareness. Impaired body perception results have been reported in many different chronic pain problems. Studies have reported that individuals with low back pain (LBP) also have body perception disturbances related to the lumbar spine. OBJECTIVES: This review aimed to determine the evidence that body awareness alterations in individuals with LBP. DESIGN: Systematic review. METHOD: Studies were searched in PubMed, Cochrane Library, and Pedro databases up to January 2021. Each database was searched independently, according to a specific iteration research string. The protocol record of the systematic review was entered into the PROSPERO system. RESULTS: Nine studies were included in this research. We found evidence to support more perceptual impairments in patients with LBP than healthy counterparts. In addition, the results of the studies showed an association between disrupted body awareness and pain severity, pain catastrophizing, and disability. CONCLUSIONS: Body perception disturbances in LBP seem to be a promising path that needs to be further explored, with the ultimate goal of developing treatment contents targeting body awareness as a more comprehensive and valid evaluation and therapeutic method. TRIAL REGISTRATION: The registration number was CRD42021235934.

Subjective social status across the past, present, and future: status trajectories of older adults.

Beyond objective indicators of social status (e.g., income or education), the subjective social status (SSS; i.e., the self-assessed position in a social hierarchy) is associated with psychological well-being and physiological functioning. Existing research has focused on older adults' current status evaluations, neglecting perceived temporal stability or change in SSS which can further impact self-perception and emotional well-being. In the present study, we examined older adults' (N = 191; mean age = 73.5) SSS with regard to their past, present, and future. Examining SSS for multiple time-points allowed us to identify profiles representing trajectories of status from the past to the future by conducting latent profile analysis. Furthermore, we tested associations of the identified trajectory-profiles with aging anxiety and negative affect. Results showed that, on average, participants anticipated higher future status losses than they had experienced in the past, regardless of age. In the more nuanced profile analysis, we identified four trajectory-profiles: A high (17%), a moderate (57%), and a low perceived social status (14%) trajectory, as well as a profile representing a perceived decrease in status (12%). While a lower status was associated with more aging anxiety and negative affect, most aging anxiety and negative affect was found for profiles representing a low initial status-level and a perceived decrease in status. Findings implicate that social status comparisons with others but also status comparisons with past- and future-selves are relevant for older adults. The discussion highlights the benefits of improving or stabilizing subjective assessments of status in later adulthood.

A cohort study of self-perception of ageing and all-cause mortality among older adults in China: a multiple mediators analysis.

BACKGROUND: Positive self-perception of aging (SPA) is a well-known predictor of longevity, while how and to what extent SPA is linked with all-cause mortality among older adults is still unclear. This study aims to elucidate the relationship between positive SPA and all-cause mortality and its potential mediators among Chinese older adults. METHODS: This is a 20-year dynamic cohort study conducted among 22,957 older adults aged ≥ 65 years old from a nationally representative sample. Positive SPA was measured using a validated 7-item scale. Potential mediators including health behaviors and social participation were collected using a self-reported questionnaire. Cox proportional hazards regression models were conducted to examine the association between positive SPA and all-cause mortality. A mediation analysis was conducted to determine whether health behaviors and social participation mediated the association between SPA and all-cause mortality. RESULTS: Throughout follow-up (median [interquartile range], 46 [21-84] months), all-cause mortality was 87.4%. Compared with older adults with the lowest quartile positive SPA, hazard ratio(HR) of all-cause mortality among older adults with the second, third, and fourth quartile of positive SPA was 0.96(95%CI:0.93-1.00), 0.93(95%CI:0.90-0.99), and 0.92(95%CI:0.87-0.96) respectively after controlling for all potential mediators and covariates. The mediation analysis showed that regular daily vegetable intake, physical activity, and high social participation explained 41.1-48.5% of the variance in the association between positive SPA and all-cause mortality. CONCLUSIONS: In this cohort study, we found that high positive SPA was associated with decreased all-cause mortality directly, and indirectly through healthy lifestyle behaviors and social participation. These findings suggest that interventions targeted at promoting or maintaining positive SPA may contribute to healthy ageing among older adults in China.

The Relationship and Effects of Self-Esteem and Body Shape on Eating Disorder Behavior: A Cross-Sectional Survey of Chinese University Students.

BACKGROUND: Eating disorders (EDs) have become a global public health concern among adolescents and young adults. However, Chinese university students exhibit a high prevalence of eating disorders. This study aims to investigate the effects of self-esteem (SE) and body shape (BS) on ED behaviors among Chinese university students. METHODS: Using random sampling, 946 Chinese university students (aged 18 to 24, M = 19.94, SD = 1.04) participated in a survey comprising the Sick, Control, One, Fat, and Food Questionnaire (SCOFF-Q), the Body Shape Questionnaire (BS-Q), and the Rosenberg Self-Esteem Scale (RS-S) to assess their eating disorder or non-eating disorder (NED) behavior. RESULTS: There was a significant positive correlation between body shape and eating disorder behaviors (r = 0.19, p < 0.01), while there was a significant negative correlation between self-esteem and eating disorder behaviors (r = -0.14, p = 0.001 < 0.01). Gender was a moderating factor in the relationship between body shape and eating disorder behaviors (t = 3.14, p = 0.002 < 0.01), while parents' marital status was a moderating factor in the relationship between self-esteem and eating disorder behavior (t = 2.72, p = 0.007 < 0.01). Body shape (z = 6.47, p = 0.001 < 0.01), self-esteem (z = -2.81, p = 0.005 < 0.05), and gender (z = 3.06, p = 0.002 < 0.01) significantly influenced eating disorder behavior among Chinese university students aged 18-24 years. CONCLUSIONS: There was a direct effect between body shape and self-esteem and eating disorder behaviors among Chinese university students aged 18-24 years. Alarmingly, female university students are becoming susceptible to external influences on self-esteem and body shape, leading to eating disorder behaviors at an increasingly younger age in China.

Dataset of media practices for informational, educational, and entertainment purposes in Peru: Uses and gratifications approach.

This database consists of the Peruvian media diet in a post-pandemic context. Specifically, it examines how Peruvians define and utilise media to create environments for information, learning, and entertainment. Since the pandemic, the relationship that users have developed with the media has intensified and changed, fostering new uses and interactions. However, our data demonstrates that the Peruvian public maintains a critical role towards mass media (broadcasting model) [1], which motivates them to seek out media and platforms that cater to their interests and expectations. In this regard, we compare three axes of analysis (information, education, and entertainment), taking socio demographic variables, to produce a baseline that is useful for specific research projects. Through a quantitative approach we explored the expectations, decisions, forms of interaction, and satisfactions that users obtain in their relationship with the media, offering new theoretical insights based on emerging data, such as the level of planning in content consumption or the role that traditional media play in different age and socioeconomic groups.

The Association of Body Image Perceptions with Behavioral and Health Outcomes among Young Adults.

This study was conducted on 5 March 2024, by the Universidad Europea de Madrid. This study aims to explore how body image perceptions influence health behaviors and mental and physical health outcomes among a specific group of 605 young adults aged 20 to 35 engaged in strength training regimes. To measure these perceptions, the Multidimensional Body-Self Relations Questionnaire (MBSRQ) was employed, an advanced tool that assesses multiple dimensions of body image through its subscales, including feelings of physical attractiveness, investment in one's appearance, and satisfaction with different body areas. Participants were segmented into two groups based on a median split of their self-reported body image. The survey assessed a diverse array of variables, including demographic details, physiological data, resistance training routines, and psychological attributes. In this revision, we consistently use the term 'dietary habits' to ensure clear and uniform language when discussing eating patterns. Notable differences were observed in dietary habits and exercise engagement, influenced significantly by body image perceptions. Negative body image was linked to less healthy dietary habits, diminished physical activity, and worse psychological outcomes, such as increased anxiety and depression. Conversely, a positive body image was associated with healthier dietary habits, more frequent physical activity, and better psychological health. The findings suggest that interventions aimed at improving body image could be crucial for enhancing overall health within this specific demographic. Due to the non-representative nature of the study group, conclusions are cautiously presented as applicable only to similar populations engaged in strength training. This study underscores the need for holistic strategies that encourage positive body image to improve both physical and psychological health outcomes in young adults.

Educational training and nursing professional self-perception in Mongolia: A prospective observational pre-post design study.

AIMS: To determine whether professional self-perception of nurses in Mongolia improves following an educational intervention and to identify differences in scores among participant subgroups. DESIGN: A prospective observational pre-post design. METHODS: Using a convenience sample of 67 nurses in Mongolia in 2019, the Nursing Professional Values Scale-3 instrument was used pre- and post-intervention. Independent and paired sample t-tests were conducted. Data were analysed using IBM SPSS 28.0.1.1 and Stata/SE 16.1. This study complied with the STROBE checklist. RESULTS: Of the 67 nurses, 92.0% were female, mean age was 32.15 years (SD 8.96), 70.0% held a bachelor's degree, 58.0% had 5 or more years' nursing experience and 51.0% were members of a professional nursing organization. After participating in the educational training, nurses reported higher overall professional self-perception as well as across subscales: activism, professionalism and caring. CONCLUSION: Considering the nursing shortage in lower-middle-income countries, it is important to recognise the influence of nurses' professional self-perception on nursing retention. This study highlights the significant role continuing educational opportunities play in increasing nurses' professional self-perception. It is imperative to explore ways of improving this perception and focusing on subgroups of nurses to help guide the use of limited resources. Further research is necessary to include nurses in other areas of Mongolia. IMPLICATION FOR THE PROFESSION: Accurately assessing nursing professional self-perception and providing educational opportunities could improve nursing professional self-perception, nursing satisfaction, patient safety and nursing retention in lower-middle-income countries. IMPACT: What problem did the study address? This study meets the need for current study on the nursing professional self-perception of nursing from the perspective of nurses in Mongolia. It addresses the dangerous nursing shortage in Mongolia by determining if an educational intervention could improve nursing professional self-perception and thus improve nursing job satisfaction and retention. What were the main findings? Mongolian nurses in this study scored in the top quartile of the NPVS-3, indicating a baseline high NPSP. Educational intervention (including translated oral education and written clinical pathways) significantly improved the nurses' professional self-perception. Nurses were eager for training in other clinical and leadership topics. Where and on whom will the research have an impact? This research can be impactful for nurses, nurse leaders and policy makers in low- and lower-middle-income countries. Specifically for nurses in Mongolia, with increasing technologies and services such as cardiac catheterization laboratories becoming available, more education in these nursing specialty areas is imperative. Professional Nursing Organizations are poised to foster more educational offerings to their members and to increase membership. Nursing education provided by international volunteer nurses with Non-Governmental Organizations can improve NPSP in nurses in LMICs. REPORTING METHOD: This study complied with the STROBE checklist. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

The role of marital satisfaction and social activities on parents' self-perception: evidence from Greek families of children with and without disabilities.

The purpose of this study is to explore the association between marital satisfaction and social activities with parents' self-perception. Self-perception included parents' sense of self and their attitudes and beliefs about who they are as individuals and as parents. Three hundred and twenty-seven parents, having either a child with (D1-target group) or without (D2-control group) a disability, were enrolled in the study. We hypothesized that self-perception of parents in the target group would be lower in all measures. We also hypothesized that low self-perception will correlate with parents' marital satisfaction and social activities. We found that parents of a child with disabilities reported significantly lower levels in all domains (self-perception, marital satisfaction and social activities) than parents of children without disabilities. Moreover, multigroup analyses confirmed that the structural paths between self-perception, marital satisfaction and social activities do not differ between D1 and D2 parents (χ2(127, N = 327) = 134.62, p>.05, CFI = 1.00 ≥ 0.90, RMSEA=.063 ≤ .080, SRMR = 0.054 < 0.08, TLI = 1.000 > 0.95). Results are discussed in terms of children's educational placement and their implications on children with and without disabilities unobstructed co-development and co-existence with their parents in the family context.

Cognitive flexibility's role in shaping self-perception of aging, body appreciation, and self-efficacy among community-dwelling older women.

BACKGROUND: Cognitive flexibility, the capacity to adjust to new information, affects how aging is perceived. In Egyptian culture, older women's views on aging are shaped by societal gender roles and expectations. These views influence their body image and belief in their abilities, all melded by cultural standards and values. AIM: Investigate the mediating role of cognitive flexibility in the relationship between self-aging perception, body appreciation, and self-efficacy among community-dwelling older women. METHODS: A correlational analytical design was used on 200 women aged 60 years or older using the Cognitive Flexibility Inventory, Self-Perceptions of Aging, General Self-Efficacy Scale, and Body Appreciation Scales. Structural equation modeling was used in the analysis. RESULTS: The study found that cognitive flexibility is positively related to self-perception of aging and body appreciation and is also significantly related to general self-efficacy. However, no significant relationship was found between body appreciation and general self-efficacy. Additionally, the study found that cognitive flexibility partially mediates the relationship between self-perception of aging and body appreciation and fully mediates the relationship between body appreciation and self-efficacy. CONCLUSION: Cognitive flexibility is vital in the relationships between self-perceptions of aging, body appreciation, and self-efficacy among older women. Therefore, nursing interventions targeting cognitive flexibility are recommended to promote positive self-aging perceptions, body appreciation, and self-efficacy in this population.

Naturalistic use of psychedelics does not modulate processing of self-related stimuli (but it might modulate attentional mechanisms): An event-related potentials study.

Classic psychedelics are able to profoundly alter the state of consciousness and lead to acute experiences of ego dissolution - the blurring of the distinction between representations of self and the external world. However, whether repeated use of psychedelics is associated with more prolonged and permanent modifications to the concept of self remains to be investigated. Therefore, we conducted a preregistered, cross-sectional study in which experienced psychedelics users (15 or more lifetime experiences with psychedelics; N = 56) were compared to nonusers (N = 57) in terms of neural reactivity to a Self-name (i.e., each participant's own name) stimulus, which is known to robustly activate a representation of self. Two control stimuli were additionally used: an Other-name stimulus, as a passive control condition in which no reaction was required, and a Target-name stimulus, to which participants provided a manual response and which thus constituted an active control condition. Analysis of the amplitude of the P300 ERP component evoked by the Self- or Target-names revealed no difference between the psychedelics users and nonusers. However, psychedelic users exhibited increased P300 amplitude during perception of Other-names. In addition, in comparison to nonusers, psychedelics users exhibited a smaller increase in P300 amplitude when processing the task-relevant Target-names (in relation to both Self- and Other-names). Therefore, our data suggests that regular naturalistic use of psychedelics may not be related to long-term changes in the representation of self, but it might potentially affect the allocation of attentional resources to task-relevant stimuli.

Sociocultural interactions and self-perception of health in older adults from an active participation centre: A qualitative study.

INTRODUCTION: Promoting healthy ageing is a global priority. Active Participation Centres are potentially key in fostering psychosocial and emotional health, contributing to a fulfilling and active lifestyle for older adults. AIMS: The study explores self-perceived health, perceptions of sociocultural participation, emotions that emerged when sociocultural participation, and preferences among older adults engaged in community socio-cultural activities from an Active Participation Centre. METHODS: We realised a hermeneutic study; interviews with nine older participants were conducted. Hermeneutic considerations were employed for data analysis. RESULTS: Findings reveal the centre's significance as a therapeutic space, positively influencing emotional well-being, fostering social connections, and offering diverse activity preferences. CONCLUSION: This study underscores the nuanced interplay between sociocultural engagement and self-perceived health, emphasising the need for holistic approaches to promote well-being among older adults attending Active Participation Centres.

Effect of weight satisfaction on adolescent facial and dental satisfaction.

PURPOSE: To investigate if facial and dental satisfaction is related to body fat percentage and body weight satisfaction. METHODS: A self-administered questionnaire was applied to adolescents from a Private School in Southern Brazil containing sociodemographic (sex and age) and self-perception variables. Adolescents were asked about their perceptions concerning dental problems. Body fat percentage was collected using bioelectrical impedance analysis. RESULTS: A total of 372 adolescents were examined. Most adolescents were satisfied with their dental (81.7%) and facial appearance (87.6%), while 39% of adolescents were satisfied with their body weight. Poisson regression model showed that adolescents who expressed satisfaction with their body weight (PR = 1.12, 95%CI 1.06-1.19) and were satisfied with their dental appearance (PR = 1.24, 95% CI 1.08-1.41) exhibited a positive association with facial satisfaction. Adolescents dissatisfied with dental color (PR = 0.88, 95%CI 0.80-0.97), those reporting dental pain (PR = 0.88, 95%CI 0.80-0.97), and individuals with obesity (PR = 0.91, 95%CI 0.83-0.99) demonstrated a decrease in facial satisfaction. Adolescents aged 16 to 19 years (PR = 1.08, 95% CI 1.01-1.15) and those satisfied with their facial appearance (PR = 1.20, 95%CI 1.01-1.43) exhibited a higher prevalence of dental satisfaction. Conversely, adolescents dissatisfied with dental color (PR = 0.74, 95% CI 0.66-0.82) and those with misaligned teeth (PR = 0.63, 95%CI 0.55-0.73) reported lower levels of dental satisfaction. Parametric g-formula analysis found that the association between body fat and facial satisfaction was mediated by body weight satisfaction (p = 0.001). CONCLUSIONS: While dental satisfaction was not influenced by corporeal characteristics, facial satisfaction was influenced by dental and body weight satisfaction. Obese adolescents had low facial satisfaction.

Exploring the Relationship Between Acoustic Measurements and Self-Perception of Voice in Trans Women.

OBJECTIVE: This study aimed to explore the strength and direction of the relationship between spectral cepstral-based, time-based acoustic measures and the self-perception of voice in trans women. METHODS: Forty-eight trans women were included in the study. Analysis of the sustained vowel phonation was performed using Multidimensional Voice Profile Analysis (MDVP), and spectral-cepstral analyses of the sustained vowel phonation, all-voiced weighted sentence, and spontaneous speech were made via Analysis of Dysphonia in Speech and Voice (ADSV) software. For self-perceptual evaluations, the Trans Woman Voice Questionnaire (TWVQ) and the Self-perception of Voice Femininity Scale (SPVF) were used. The correlation between MDVP, spectral-cepstral parameters, and TWVQ and SPVF scores was calculated. RESULTS: The present study found a positive relationship between F0, SPVF, and TWVQ. Among the perturbation parameters, the jitter was the only one found to correlate with SPVF and TWVQ. The CPPF0 parameter was found to be associated with a more feminine voice perception and a higher voice-related quality of life in all speech samples in the present study. In addition, higher CPP values achieved from vowel phonation were associated with less feminine voice perception and lower voice-related quality of life. The present study also suggests a weak correlation with the SPVF and Cepstral Peak Prominence Standard Deviation (CPPF0 SD) of the spontaneous speech sample in a negative direction. CONCLUSIONS: This study found weak and moderate levels of correlations between F0, jitter (%), CPP, CPPF0, CPPF0 SD parameters, and self-perceptual measures. These findings suggested that such a level of relationship is attributable to the fact that these tools evaluate different aspects of voice in accordance with the International Classification of Functioning System. According to this pioneering study, it would be beneficial to incorporate spectral-cepstral measures into the objective assessment protocol for trans women's voices.

Psychometric Properties of the Pictorial Scale of Perceived Movement Skill Competence for Young Norwegian Children.

The objective of this study was to examine the psychometric properties of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) for young Norwegian children, a scale that is aligned with skills assessed in the Test of Gross Motor Development- Third Edition. We used convenience sampling to recruit 396 Norwegian-speaking children (7-10-year-olds) who completed the PMSC. A confirmatory factor analysis (CFA) confirmed factorial validity for the proposed three-factor model of the PMSC, encompassing measures of self-perceived ball, locomotor, and active play competence. Internal item consistency coefficients of these sub-scales were acceptable, and subsequent measurement invariant analysis found a gender difference such that boys rated their competence higher than girls in running, jumping forward, hitting a ball (racket), kicking, throwing a ball and rope climbing, while girls rated themselves higher, compared to boys, in galloping and skating/blading. Furthermore, there was a slightly better model fit for boys than for girls. Several items were significantly related to children's age, and the three-factor model exhibited differential age related factor mean differences across older and younger children. Overall, we found the PMSC to have acceptable psychometric properties for confident use in assessing perceived motor competence among 7-10-year-old Norwegian children, though we observed age and gender differences in children's responses that warrant careful interpretation of results and further research investigation.

Antecedents and outcomes of cyberbullying among Chinese university students: verification of a behavioral pathway model.

Introduction: Cyberbullying is a commonly-seen and hotly-debated social topic around the globe. This negative behavior is the source of many disastrous events, and so leading government bodies, organizations, schools and social communities attach great importance to addressing this topic. However, there is still much work to do in order to be clear about the causes of cyberbullying. Methods: The previous research cases were mostly viewed from the victims' perspectives; however, there is no comprehensive understanding of the perpetrators' viewpoints. Therefore, based on Social Cognitive Theory (SCT) and analysis of discussion in the literature, the following six variables were chosen as the focus of this study: overconfidence, excessive moral sense, cyberbullying, perceived value, happiness, and continued cyberbullying intention. This study established a research model of continued cyberbullying intention, which was verified by Structural Equation Modeling. In order to achieve the aims of the study, Chinese university students with an average age of 20.29 (SD = 1.43) were recruited as participants, from whom 1,048 valid questionnaires were collected. Results: The research results are as follows: 1. Overconfidence and excessive moral sense positively predicted cyberbullying behaviors; 2. Overconfidence positively predicted excessive moral sense; 3. Cyberbullying positively predicted perceived value and sense of happiness; and 4. Perceived value and sense of happiness positively predicted continued cyberbullying intentions. Conclusion: Students' biased self-perception significantly predicts their cyberbullying behaviors and continued cyberbullying intention. What is more, it is interesting to learn that perpetrators will continue to exhibit cyberbullying behaviors when they believe that what they do (cyberbullying) is valuable or allows them to experience positive feelings; this requires our attention.

Understanding the impact of women's correct risk perception on human immunodeficiency virus diagnosis: Insights from South Africa.

BACKGROUND: South African women have the highest burden of HIV infections globally. We investigated the temporal trends and the impact of key factors associated with HIV diagnosis among a nationally representative cohort of South African women. METHODS: Total of 24,657 women who participated in the National HIV, Behaviour and Health Surveys conducted from 2002-to-2017. RESULTS: Despite decades-long prevention efforts, we observed a significant increase in HIV prevalence over time (22% in 2002 to 21% in 2005-2008 and 29% in 2012-2017). Overall, 46% of the women living with HIV were not aware of their risk of HIV with age-specific disparities. Our findings revealed compelling evidence between HIV seropositivity and high HIV risk-perception (adjusted Odds Ratio (aOR):1.47 to 3.29) which increased overtime and exceeded the other factors. At a population-level, 45% of the HIV diagnoses were exclusively associated with women who believed they were at risk of HIV in 2012-2017. Women who reported using condoms at last sexual act were also at increased risk of HIV infection, with a population attributable risk of 18% (2002) to 21% (2012-2017). CONCLUSION: There is an urgent need for culturally, socially, and linguistically appropriate prevention and awareness campaigns with realistic, non-confrontational messages.

Objective and subjective measures of air pollution and self-rated health: the evidence from Chile.

PURPOSE: The literature exploring individual differences in self-rated health has grown fast in recent years. Self-rated health (SRH) is a good indicator of general health status. This empirical study explores the association between outdoor air pollution and SRH in Chile. This type of analysis is infrequent in Latin America. METHODS: We used objective and subjective air pollution measures. The first corresponds to PM2.5, and the latter to the perception of a high level of air pollution. Drawing on data from two independent and repeated nationwide surveys over the period 2006-2017 at the individual level in Chile, we performed repeated cross-sectional analyses for each year of survey application. Ordered Logit (OL) and Logit (L) multivariate models were used to investigate the association between SRH and air pollution measures, considering other socioeconomic and demographic covariates. RESULTS: We found that the higher is the level of air pollution, the lower the SRH in Chile, regardless of whether air pollution is physically measured or perceived by respondents. The results were consistent over the years in the sign and significance of regression coefficients using two surveys and two forms of the outcome variable. CONCLUSIONS: Our findings add evidence that air pollution is a relevant determinant of SRH. In addition, they show that subjective measures of air pollution can be as reliable as physical measures in the analysis of the association between air pollution and human health.

Self-perceived body weight and weight status: analysis of concordance by age group and sex.

OBJECTIVES: Previous studies suggest that there is discordance between actual weight status and body-weight perception. This fact has implications when it comes to designing public health interventions. The aim of this study was to estimate the prevalence of the different categories of weight status and body-weight perception and to analyse their concordance in a representative Spanish population sample. STUDY DESIGN: Cross-sectional study. METHODS: Data were sourced from the 2018 Galician Risk Behaviour Data System, with the target population being all persons aged 16 years and above. We collected data on self-perceived body weight and assessed weight status on the basis of body mass index (BMI). BMI was estimated using self-reported measures of weight and height. To estimate concordance, Cohen's kappa coefficient, both unweighted and weighted with Cicchetti weights, was calculated. RESULTS: Data were obtained for 7853 individuals aged 16 years and above, whereas the overall unweighted concordance was 0.393 (95%CI: 0.377-0.409), with an agreement percentage of 61.6%, weighted concordance was 0.503 (0.490-0.517), with an agreement percentage of 86.6%. The highest concordance between self-perceived body weight and weight status was observed in women. By age group, the highest concordance was observed in the youngest group (16-24 years) for the BMI categories of underweight and overweight, and in the 45-64 age group for the category of obesity. CONCLUSIONS: The results highlight the existence of differences between self-perceived body weight and weight status, according to sex and age.

Association Between Self-Perception of Aging and Long-Term Mortality in Elderly Patients with Hypertension in Rural China: A Possible Beneficial Effect of Nut Intake.

Purpose: Previous research has consistently shown that self-perception of aging (SPA) is an important predictor of health and longevity, while Chinese rural elderly patients with hypertension had poorer SPA. Whether it was associated with their mortality kept unknown. The objective of this study was to investigate the long-term mortality and analyze the association between SPA and this mortality in the specific context of rural elderly patients with hypertension. Patients and Methods: This study is a longitudinal investigation of the mortality in elderly patients with hypertension in rural Suzhou, China. Sociodemographic and clinical data, SPA, and six-year mortality were investigated. We used binary logistic regression and subgroup analyses to assess the effect of SPA at baseline on six-year mortality. Results: A total of 280 hypertensive patients aged 60 years and older participated in the study, of whom 21 died, with a six-year mortality rate of 7.5%. After controlling for covariates, the "Emotional representation" dimension (OR=2.824, 95% CI:1.034-7.712) in SPA remained a risk factor for death. In subgroup analyses of the group aged 75 years and older, high scores on the "Timeline cyclical" (OR=14.125, 95% CI: 1.258-158.593) and "Emotional representations" (OR=2.567, 95% CI:1.066-6.182) dimensions were associated with a higher risk of death, while weekly nut intake may have mitigated the negative SPA effect on mortality. Conclusion: Poorer self-perception of aging was associated with a high risk of mortality in rural elderly patients with hypertension, while the habit of weekly nut intake might help reduce this risk in the group aged 75 years or older.
