Research on the Design of Child-Friendly Landscape Space in Chengdu Crown Community Based on SDG

Objective: This study aims to explore and implement a child-centred landscape space design strategy to support the Sustainable Development Goals (SDGs), especially in the old residential environment of the Crown Community in Chengdu, China. Theoretical Framework: The study constructs a theoretical framework for child-friendly communities based on the United Nations' children's rights and the Sustainable Development Goals (SDGs), especially Goal 11 (Sustainable Cities and Communities) and Goal 13 (Climate Action). Method: Through literature review and field research, combined with questionnaires, this study collected 120 child samples, analyzed their behavioural needs, and proposed corresponding landscape space design strategies. Research Implications: The study found that the needs of children in the Crown Community mainly focus on natural experience, research experience, game interaction, and hiding exploration. The design strategy transforms the existing space into an art garden, a book garden, and a children's playground to meet these needs and promote the realization of SDGs. Research Significance: The study emphasizes that improving children's living environment through landscape design is significant to achieving the goals of sustainable cities and communities in SDGs. Originality/Value: This study provides an innovative approach to integrating SDGs into renovating old communities and offers a new perspective for designing child-friendly landscape spaces, which will help promote the renewal of old urban communities and the construction of child-friendly cities.

Prevalence of mild cognitive impairment and its association with malnutrition in older Chinese adults in the community.

This study aims to characterize the prevalence and associated factors of cognitive impairment in older adults within Chinese community settings. Research exploring the interrelation between malnutrition and cognitive impairment in the older adult community-dwelling population is scarce. The impact of nutritional status on cognitive function in aging adults has not been definitively established. A cross-sectional survey was conducted in one urban and one rural community in Chengdu, China, from October 2022 to March 2023. The sample included 706 older adults. Logistic regression was utilized to determine independent risk factors for mild cognitive impairment (MCI). The study found a significant prevalence of MCI at 32.0% among the older adult population. Among those suffering from malnutrition, 55.6% were affected by MCI. The logistic regression analysis indicated that malnutrition risk (OR = 2.192, 95% CI 1.431 to 3.357, p < 0.001), rural residence (OR = 1.475, 95% CI 1.003 to 2.170, p = 0.048), age (70-79 years old; OR = 2.425, 95% CI 1.611 to 3.651, p < 0.001; ≥80 years old: OR = 4.773, 95% CI 2.571 to 8.859, p < 0.001), male (OR = 1.584, 95% CI 1.085 to 2.313, p = 0.017), middle education level (OR = 0.986, 95% CI 1.627 to 5.482, p < 0.001), and ADL dependence (OR = 1.810, 95% CI 1.158 to 2.827, p = 0.009) were significantly associated with the occurrence of MCI. The findings indicate a widespread occurrence of MCI in community-dwelling older Chinese adults. The association between malnutrition, as measured by the Mini Nutritional Assessment-Short Form (MNA-SF), and cognitive decline is evident. Older adult individuals with nutritional risk, advancing age, rural residence, male gender, moderate education, and ADL dependency are at increased likelihood of developing MCI. Longitudinal research is needed to clarify the temporal relationships between MCI, demographic factors, and whether improvements in nutritional status or ADL can reduce the incidence of MCI in this population.

A Study on the Current Situation of Public Service Facilities’ Layout from the Perspective of 15-Minute Communities—Taking Chengdu of Sichuan Province as an Example

With the rapid expansion of cities, the construction of 15-minute communities has become an important way to improve the urban living environment and enhance the quality of life of residents. In this study, based on the perspective of a 15-minute community in Chengdu, the current situation of the spatial layout in the 12 main urban districts of 15,941 public service facility points is studied. Additionally, the matching relationship between the supply and demand of five major categories (19 subcategories) of public service facilities and the population is assessed by using the kernel density analysis method, the Gaussian two-step floating catchment area method, the hierarchical analysis method and the bivariate spatial autocorrelation. Finally, suggestions for the optimization of basic service facilities are made in the light of the current development situation in Chengdu. The results show that (1) there is a large spatial heterogeneity in the distribution and accessibility of public service facilities in the study area; (2) there is a mismatch between the supply and demand of public service facilities and the population in Chengdu; and (3) in order to further optimize the allocation of public service facilities, it is necessary to focus first on areas where demand exceeds supply. This study built a framework for assessing the current status of spatial distribution of public service facilities, which measures the 15-minute accessibility of basic public service facilities in a more comprehensive way and bridges the gap of previous single-type studies, which make it difficult to make comprehensive optimization recommendations directly. Meanwhile, the bivariate spatial autocorrelation reveals the areas of mismatch between supply and demand more accurately, and more clearly shows the areas that need to be focused on for optimization by policy makers.

Multiple geriatric syndromes in community-dwelling older adults in China

This study aims to assess the prevalence of geriatric syndromes and identify factors associated with multiple geriatric syndromes in community-dwelling older adults in China. We utilized a convenience sampling method to recruit older adults and from one rural and one urban community in Chengdu, China, from October 2022 to March 2023. A total of 706 older adults aged 60 years or older were included. Ten geriatric syndromes were investigated including two mental disorders: depressive symptoms, cognitive impairment; and eight somatic disorders: pain, falls, sleep disturbance, constipation, polypharmacy, multimorbidity, malnutrition and frailty. Multiple geriatric syndromes were defined as an individual having two or more geriatric syndromes. The data obtained were analysed using descriptive statistics. The independent risk factors for multiple geriatric syndromes were assessed using a logistic regression model. This study found that 90.5% of the participants had at least one geriatric syndrome, with 72.8% experiencing multiple geriatric syndromes. The top four geriatric syndromes in our study were polypharmacy (58.5%), malnutrition/at risk of malnutrition (43.1%), multimorbidity (42.1%), and frailty/prefrailty (34.3%). Of the older adults, 368(52.1%) had only somatic disorders, 18(2.5%) had only mental disorders and 253 (35.8%) had somatic-mental disorders. According to the logistic regression analysis, residence, age, marriage, BMI, and self-related health were significantly associated with multiple geriatric syndromes among older adults. This study highlights that multiple geriatric syndromes are prevalent among community-dwelling older adults in China, and underscores the significance of certain demographic factors in their occurrence. Future longitudinal studies are needed to establish the temporal relationship between multiple geriatric syndromes and these demographic factors, as well as to explore causal relationships and effective prevention strategies for geriatric syndrome.

Prevalence, cognitive characteristics, and influencing factors of amnestic mild cognitive impairment among older adults residing in an urban community in Chengdu, China.

Dementia is a significant public health concern, and mild cognitive impairment (MCI) serves as a transitional stage between normal aging and dementia. Among the various types of MCI, amnestic MCI (aMCI) has been identified as having a higher likelihood of progressing to Alzheimer's dimension. However, limited research has been conducted on the prevalence of aMCI in China. Therefore, the objective of this study is to investigate the prevalence of aMCI, examine its cognitive characteristics, and identify associated risk factors. In this cross-sectional study, we investigated a sample of 368 older adults aged 60 years and above in the urban communities of Chengdu, China. The participants underwent a battery of neuropsychological assessments, including the Mini-Mental State Examination (MMSE), the Clinical Dementia Rating (CDR), Auditory Verbal Learning Test (AVLT), Wechsler's Logical Memory Task (LMT), Boston Naming Test (BNT) and Trail Making Test Part A (TMT-A). Social information was collected by standard questionnaire. Multiple logistic regression analysis was utilized to screen for the risk and protective factors of aMCI. The data analysis included 309 subjects with normal cognitive function and 59 with aMCI, resulting in a prevalence of 16.0% for aMCI. The average age of participants was 69.06 ± 7.30 years, with 56.0% being females. After controlling for age, gender and education, the Spearman partial correlation coefficient between various cognitive assessments and aMCI ranged from -0.52 for the long-term delayed recall scores in AVLT to 0.19 for the time-usage scores in TMT-A. The results indicated that all cognitive domains, except for naming scores (after semantic cue of BNT) and error quantity (in TMT-A), showed statistically significant associations with aMCI. Furthermore, the multiple logistic regression analysis revealed that older age (OR = 1.044, 95%CI: 1.002~1.087), lower educational level, and diabetes (OR = 2.450, 95%CI: 1.246~4.818) were risk factors of aMCI. This study found a high prevalence of aMCI among older adults in Chengdu, China. Individuals with aMCI exhibited lower cognitive function in memory, language, and executive domains, with long-term delayed recall showing the strongest association. Clinicians should prioritize individuals with verbal learning and memory difficulties, especially long-term delayed recall, in clinical practice.

Cultural empowerment: the space production and local identity effects of square dancing on middle-aged and elderly rehabilitation patients—based on a qualitative study of three square dancing communities in Chengdu, China

ABSTRACT Square dancing can serve as both a fitness and entertainment element in the psychological rehabilitation of older people. It also has the effect of providing a space and local identity with social and cultural significance for the psychological rehabilitation of older people, thus supporting their psychological rehabilitation treatment. Using questionnaires and interviews based on the case study of three square dance communities in Chengdu, China. According to the findings of the study, square dance serves the purpose of reconstructing the collective life of local middle-aged and elderly people in rehabilitation. A sense of belonging and assisting psychological rehabilitation needs; and for middle-aged and elderly psychological rehabilitation people who immigrate, square dancing can help repair the social network broken by migration, and help middle-aged and elderly psychological rehabilitation people to establish a similar. The role of ‘hometown community’ restores their familiar village-style ‘acquaintance society’ and aids psychological restoration. Simultaneously, this study offers a unique research approach for investigating the beneficial psychological intervention provided to middle-aged and senior psychological rehabilitation patients in rehabilitation treatment.

Non-traditional Gender Role Parents on the LGBTQ+ Community in Chengdu, China: A Cultural and Psychosocial Examination

The impact of non-traditional gender role parenting on the LGBTQ+ community in the Chengdu area, especially in an urban environment like Chengdu, which is known for its openness and multiculturalism is worthy of academic attention. The study was conducted primarily through both quantitative and qualitative methods: online surveys and census data were used for quantitative analysis, while in-depth interviews and focus group discussions were used for qualitative analysis. This study proposes four main hypotheses: 1) there are more parents with non-traditional gender roles relative to traditional gender roles in Chengdu; 2) children from families with non-traditional gender roles are more likely to be open about their sexual minority identities; 3) non-traditional gender role family environments may be more encouraging of children's exploration and acceptance of gender perceptions of their sexual orientations; and 4) Chengdu's social and cultural environments, specifically perceptions related to gender roles, are associated with the flourishing of the LGBTQ+ community in the city. Preliminary results show that the relative activity and openness of the LGBTQ+ community in Chengdu is significantly higher than in other regions, which is related to the higher proportion of non-traditional gender role households in Chengdu. This study emphasizes that although sexual orientation is considered an intrinsic and inherent characteristic, family environment and socio-cultural factors also play an important role, especially in a more diverse and open urban context such as Chengdu. This provides a valuable perspective for further research on the cultural and social acceptance of sexual minorities within China.

Association of daily health behavior and activity of daily living in older adults in China

This study aims to describe the activity of daily living (ADL) situation and determine the relationship between health behavior and ADL among older adults in China. A cross-sectional, observational study was conducted in one urban community and one rural community in Chengdu (a city located in Southwest China), China, from October 2022 to March 2023. A total of 706 older adults were included in this study. The associations between health behaviour and ADL were assessed by logistic regression model. Of the 706 older adults, 169 (23.9%) were disabled in ADL. According to the logistic regression analysis, age (60–69 years old: OR = 0.015, 95% CI 0.007 to 0.035, P < 0.001; 70–79 years old: OR = 0.116, 95% CI 0.060 to 0.227, P < 0.001), resident(OR = 0.568, 95% CI 0.330 to 0.976, P = 0.041), chronic disease (0 type: OR = 0.023, 95% CI 0.001 to 0.379, P = 0.008; 1–4 types: OR = 0.357, 95% CI 0.219 to 0.582, P < 0.001), no exercise (OR = 4.562, 95% CI 2.263 to 8.026, P < 0.001), and physical examination (OR = 2.217, 95% CI 1.294 to 3.496, P = 0.003) were significantly associated with ADL among older adults in Southwest China. This study showed that older adults had a higher ADL disability ratio. Age, resident, chronic disease, exercise and physical examination were associated with ADL among older adults. The study indicates that medium/high exercise maybe a protective factor for older adults, and nursing staff can encourage older adults to exercise when carrying out primary prevention measures. The government and public health institutions should give special attention to older adults and help them to acquire the habit of having an annual physical examination.

Total cholesterol and high density lipoprotein cholesterol ratio is associated with metabolic syndrome in a very elderly Chinese population

Metabolic syndrome (MetS) is currently a major public health challenge in young, middle aged and elderly population worldwide, but it is still not clear in very elderly population. This study was to investigate the potential association between total cholesterol and high density lipoprotein cholesterol ratio (THR) and MetS in a very elderly population in Chengdu. Totally, 1056 very elderly (aged ≥ 80 years) in Chengdu community were enrolled in this study. Geographic characteristics of participants were collected and laboratory measurement was performed. Metabolic syndrome (MetS) was defined according to the Chinese and the international diabetes federation (IDF) criteria, respectively. Logistic analysis was used to investigate the potential association between the THR and MetS. Receiver operating characteristic curve (ROC) analysis was used to evaluate the efficiency of THR in MetS predicting. Finally, 1038 participants were included in statistical analysis. The mean age was 83.6 ± 3.4 years and 52.6% participants were men and 21.6% suffered from MetS. Participants with MetS had relatively higher waist circumference, body weight, blood pressure, fast plasma glucose level, non-high density lipoprotein cholesterol level and THR. The logistic analysis revealed that the THR was associated with MetS according to both the Chinese (odds ratio (OR): 3.053, 95% confidence interval (CI) 2.464–3.782, P < 0.001) and the IDF criteria (OR: 2.458, 95% CI 2.016–2.995, P < 0.001). ROC analysis found that the area under curve of the THR was 0.800 (95% CI 0.749–0.852, P < 0.001) and 0.727 (95% CI 0.669–0.786, P < 0.001) for predicting MetS according to the Chinese and the IDF criteria, respectively. The THR is associated with MetS in this community very elderly population in Chengdu.

Study on the optimization of community space and governance in typical units of Chengdu--Take xinguidong community as an example

with the development of national economy, the level of national productivity and the level of urbanization have been further improved. However, a large number of unit communities in the city are difficult to meet the daily life needs of community residents due to their old facilities, internal poverty and the gathering of elderly population. Therefore, it is urgent to carry out research on the Optimization Countermeasures of space and governance of unit communities, In order to promote the sustainable development of the city. However, the current domestic research on the direction of unit community space mainly discusses from the perspectives of land use, community space form, service facilities, transportation system, residential landscape, etc., but there is still a lack of discussion on the optimization of unit community space and community management. Taking xinguidong community in Chengdu as an example, this paper puts forward the concept of "complete community" by optimizing the space and management of the unit community, and integrates it with the "harmony" of living, so as to build an overall "harmonious community", and use the method of building a safe and healthy unit, The three-level urban public space system of large open block, middle prevention and control residential area and small isolation group has been established, which combines emergency response with normal prevention and control, and makes xinguidong community a typical case of high-quality, harmonious and livable living community in Chengdu.

Iodine Nutritional Status and Prevalence of Thyroid Disorders among Adults in Chengdu

To investigate the prevalence of thyroid disorders, iodine nutritional status and relevant risk factors among adults in Chengdu city on the basis of two population-based surveys, one conducted between 2016 and 2017 and the other, between 2019 and 2020, and to provide references for making health-related administrative decisions. Two population-based sampling surveys were conducted. The first one was done between October 2016 and December 2017, using stratified cluster random sampling to select subjects from 2 urban and 2 rural communities in Chengdu. Then, between December 2019 and February 2020, sequential cluster sampling was used to select subjects from communities in the peripheral regions of Longquanyi District, Chengdu. Both surveys covered natural populations of people who were 18 or older and who met the inclusion criteria. In the first survey, questionnaires, physical examination, thyroid ultrasound, and examinations of serum thyroid biochemical markers and urine iodine were performed, while in the second survey, only questionnaire concerning thyroid disorders and physical examination were performed. Statistical analysis of the nutritional status of iodine, the prevalence of thyroid disorders, and potential risk factor was conducted. A total of 1859 subjects were enrolled for the first survey and 16152 for the second. According to the results of the first survey, the median urine iodine concentration was 172.10 μg/L, and the group with adequate or more than adequate iodine accounted for more than 60% of the surveyed population. The prevalence of thyroid disorders was found to be 0.48% for overt hyperthyroidism, 0.43% for subclinical hyperthyroidism, 0.43% for Grave's disease, 1.34% for overt hypothyroidism, 16.62% for subclinical hypothyroidism, 16.73% for positive thyroid antibody, 12.96% for TPOAb positive, 10.06% for TGAb positive, 0.81% for goiter, 14.85% for single nodule, 14.42% for multi-nodules, and 29.26% for thyroid nodules. Excess iodine is a risk factor for subclinical hypothyroidism ( OR=1.50, 95% confidence interval [ CI]: 1.07-2.10, P<0.05), and iodine deficiency is a risk factor for multiple thyroid nodules ( OR=1.45, 95% CI: 1.02-2.05, P<0.05). The total prevalence of hyperthyroidism, hypothyroidism and Hashimoto's thyroiditis in the two surveys was 6.58% and 5.95%, respectively, showing no significant difference. The second survey lacked accurate data on thyroid nodules. The iodine nutritional status of adults in Chengdu in recent years was appropriate. The total prevalence of hyperthyroidism, hypothyroidism and Hashimoto's thyroiditis remained stable, while that of thyroid nodule increased in recent years. We should continue with the implementation of the universal salt iodization policy and reinforce efforts in monitoring. Furthermore, we should make an active effort to look into the etiology of thyroid nodules.

Research on Outdoor Space Design Strategy of "SOS Children's Village" Based on the Psychology of Troubled Children.

Despite significant interaction between children's psychology and space in welfare institutions, only a handful of empirical studies have focused on it to date. Through the investigation, analysis, and spatial classification of the psychological issues of troubled children in the SOS children's village community in Chengdu, we observed the records for 1 year and used the PHCSS-SD method innovatively to systematically and quantitatively analyze the psychology of troubled children and their perception of public space in the park. Based on the needs of hearing, vision, touch, interaction, and safety of children in distress, we selected nine evaluation factors, including daylighting, interesting pattern, participation, and touchability. Each factor was categorized into five evaluation scales for psychological measurement and analysis to provide a basis for the development of mental health and the optimization of the living environment of children in distress. Based on the SD broken line of public space, we analyzed the advantages and disadvantages of space and affirmed the crucial contributions made by the Chinese government to children's welfare. Overall, this study discusses the strategy of building outdoor public spaces in the SOS children's village community.

Community Social Capital, Family Support, Confucian Pro-Setback Coping and Geriatric Depression: Evidence from China

It is important to explore the factors influencing geriatric depression in the context of aging. This research aimed to investigate the association between community social capital and depressive symptoms among the urban elderly in China, and the mediating role of family support and Confucian pro-setback coping in the impact of community social capital on geriatric depression. Data were collected via a community survey targeting 300 adults aged 60 and above living in urban communities in Chengdu, China, in 2021. SPSS and a structural equation model were used for the analysis of data and test the proposed hypothesis. The findings showed that civic participation and social cohesion were significantly related to geriatric depression. Family support and Confucian pro-setback coping played a mediating role or chain mediating role in the associations between civic participation and geriatric depression. This research has offered support for both direct and indirect effects of community social capital on geriatric depression. Promoting community-level civic participation and social cohesion, improving family support and Confucian pro-setback coping are seen to contribute positively to the management and intervention on geriatric depression.

Combined management can decrease blood pressure: an investigation of health-seeking behaviors among hypertensive patients in urban communities in China

BackgroundHypertensive patients can freely choose informal medical facilities, such as pharmacies, community health service centres, and cardiology clinics in secondary or tertiary hospitals, as routine places for medical treatment in China currently. The proportions, influencing factors and effects of different health-seeking behaviours on blood pressure (BP) among hypertensive patients in urban communities are not clear. The aim of the study was to investigate health-seeking behaviours and the effects of different health-seeking behaviours on BP among hypertensive patients in urban communities in China.MethodsA cross-sectional survey of hypertension was conducted in urban communities in Chengdu. A total of 437 hypertensive patients seeking medical help regularly were sequentially enrolled to complete a the questionnaire on health-seeking behaviours.ResultsThe average age was 67.1 ± 7.5 years old. The control rate of BP was 41.0%, and the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were 144.2 ± 17.9 mm Hg and 75.4 ± 10.4 mm Hg, respectively. Among the hypertensive patients investigated, 62.8% chose community health service centre, 5.2% chose informal medical facilities, 21.5% chose cardiology clinics in secondary or tertiary hospitals, and 10.5% chose both community health service centre and cardiology clinics as the usual places for medical treatment. There were significant differences in education levels, proportions of home BP monitoring, establishment of chronic disease archives in the community, medication adherence and side effects of drugs among the four groups. The control rates of BP were 39.4%, 23.8%, 43.0% and 54.8% (P = 0.100), respectively. The SBPs were 145.1 ± 18.0, 150.9 ± 19.8, 143.8 ± 17.5 and 136.3 ± 15.1 mm Hg (P = 0.007), respectively, and it was significantly lower in the combined management group than in the other three groups. Compared with patients choosing community health service centre, patients in the combined management group had a significantly lower BP level (β = −0.119, P = 0.038) adjusting for age, sex, education level, establishment of chronic disease archives, medication adherence and number of antihypertensive drugs.ConclusionsCombined management with both community health service centre and higher-level hospitals can decrease BP.

The accuracy of the Ishii score chart in predicting sarcopenia in the elderly community in Chengdu

BackgroundSarcopenia is a disorder associated with age that reduces the mass of skeletal muscles, the strength of muscles, and/or physical activity. It increases the risk of fall incidence which can result in fractures, hospitalizations, limited movement, and considerably decreased quality of life. Hence, it is needed to explore candidate screening tools to evaluate sarcopenia in the initial phases. The reported studies have been revealed that the sensitivity and specificity of the Ishii score chart are higher. However, the Ishii score chart is principally based on the European Working Group on Sarcopenia in Older People (EWGSOP) consensus. Recently, the Asian Working Group for Sarcopenia (AWGS) 2019 consensus has updated its diagnostic criteria for sarcopenia,which was previously similar to the EWGSOP. Hence, it is necessary to determine whether the Ishii score chart is appropriate for use among the elderly population in China. The current study aimed to validate the precision of the Ishii score chart, within the Chinese old aged community to establish an effective model for the evaluation of sarcopenia.MethodsThe AWGS2019 sarcopenia diagnostic criteria were used as a standard, and among the elderly community, the accuracy of the Ishii score chart was determined by using indicators, including specificity, sensitivity, negative and positive predictive values, negative and positive likelihood ratios, Youden index, and receiver operating characteristic (ROC) curve.ResultsIn the elderly Chengdu community, the prevalence rate of sarcopenia was 18.38 %, 19.91 % for males and 16.91 % for females. The Ishii score chart predicts sarcopenia at an AUC value of 0.84 with 95 % confidence interval (CI), ranging between 0.80 and 0.89 for females, and at an AUC value of 0.81 with 95 % CI, ranging between 0.75 and 0.86 for males.According to the original cut-off, which was set at 120 points for females, the corresponding sensitivity was 46.91 % and the specificity was 93.22 %. The 105 cut-off points (original) set for males revealed a corresponding sensitivity of 64.94 % and the specificity of 85.46 %. However, the original cut-off value exhibited low sensitivity, hence, we selected a new cut-off value. With the new cut-off value, the sensitivity, specificity, positive and negative predictive values for sarcopenia were 75.31 %, 79.9 %, 43 %, and 94 % for females, and 70.65 %, 81.35 %, 49 %, and 92 % for males, respectively.ConclusionsThe Ishii score chart was used for the prediction of sarcopenia in the old-age people of the Chengdu community and the obtained results showed a high value of predictability. Hence, more than 95 and 102 points were suggested for males and females, accordingly which can set to be the diagnostic cut-off values for the prediction of sarcopenia.

Analysis of the Prevalence of Sarcopenia and Its Risk Factors in the Elderly in the Chengdu Community.

To understand the prevalence of sarcopenia in the Chengdu community, analyze the risk factors of sarcopenia, and provide a theoretical basis for further development of strategies for sarcopenia prevention and treatment. A total of 938 individuals aged 60 years and above were recruited from the community of Chengdu. Skeletal muscle mass was measured by the bioelectrical impedance analysis (BIA), and sarcopenia was diagnosed according to the Asian Sarcopenia Working Group (AWGS) 2019 diagnostic criteria. A scale was generated to determine the age, living habits, and chronic diseases of enrolled subjects. The Mini Mental Examination Scale (MMSE) was used to assess their cognitive function, and the Geriatric Depression Scale (GDS-15) was used to identify depression. Among the 938 residents enrolled in the study, 172 (18.34%) had sarcopenia, including 48 (5.12%) with severe sarcopenia. The prevalence of sarcopenia in males was 19.91% and 16.81% in females. According to the binary logistic regression, older age (OR = 1.104, 95%CI: 1.059-1.151) and impaired cognitive function (OR = 2.251, 95%CI: 1.145-4.424) were independent risk factors for sarcopenia in females. Among the males, older age (OR = 1.079, 95%CI: 1.037-1.124) was the independent risk factor for sarcopenia. A moderate increase in BMI reduced the prevalence of sarcopenia in both females and males. Multi-category logistic regression analysis documented that females of older age were more likely to develop severe sarcopenia (χ2 = 16.769, P < 0.01 vs. no sarcopenia), females with lower BMI were more likely to develop severe sarcopenia (χ2 = 13.654, P < 0.01 vs. no sarcopenia), females with heart disease were more likely to develop severe sarcopenia (χ2 = 5.786, P = 0.016 vs. no sarcopenia; χ2 = 5.791, P = 0.016 vs. non-severe sarcopenia), and females with impaired cognitive function were more likely to develop severe sarcopenia (χ2 = 13.381, P < 0.01 vs. no sarcopenia; χ2 = 7.529, P = 0.006 vs. non-severe sarcopenia). Males were more likely to develop severe sarcopenia with older age (χ2 = 18.435, P < 0.01 vs. no sarcopenia; χ2 = 9.8011, P=0.002 vs. non-severe sarcopenia), lower BMI (χ2 = 12.736, P < 0.01 vs. no sarcopenia), smoking (χ2 = 4.68, P = 0.031 vs. no sarcopenia; χ2 = 5.652, P = 0.017 vs. non-severe sarcopenia), and chronic obstructive pulmonary disease (COPD) (χ2 = 5.517, P = 0.019 vs. no sarcopenia). In the Chengdu community, the prevalence of sarcopenia among individuals 60 years of age or older was higher in males than in females. In elderly females, older age and impaired cognitive function were independent risk factors for sarcopenia. Women with more advanced age, decreased BMI, heart disease, and impaired cognitive function were more likely to develop severe sarcopenia. In elderly males, increased age was an independent risk factor for sarcopenia, and older age, decreased BMI, smoking, and COPD increased the probability of developing severe sarcopenia.

Screening for Sarcopenia with a Self-Reported Cartoon Questionnaire: Combining SARC-F with Finger-Ring Test.

No pictorial questionnaire is available for screening sarcopenia. We aimed to develop a self-reported cartoon questionnaire based on the SARC-F and the Finger-Ring test and to compare its diagnostic accuracy with the SARC-F and the SARC-F combined with calf circumference (SARC-CalF). A diagnostic accuracy study. Urban communities in Chengdu, China. Older adults aged ≥ 60 years. We established a multidiscipline team to design this pictorial questionnaire, entitled Self-Reported Cartoon SARC-CalF (cSARC-CalF). We used the Asian Working Group for Sarcopenia (AWGS) criteria as the "gold standard" of sarcopenia. We performed sensitivity/ specificity analyses of the three tools (cSARC-CalF, SARC-CalF, and SARC-F) and applied the receiver operating characteristics (ROC) curves and the area under the ROC curves (AUC) to compare the diagnostic accuracy of the three tools. We included 1,009 participants. Using the Youden Index method, the cutoff of the cSARC-CalF for identifying sarcopenia was set as ≥11 points. Both the cSARC-CalF and the SARC-CalF showed better sensitivity but similar specificity than the SARC-F for identifying sarcopenia (sensitivity: 33.3%, 41.4%, and 23.0%; specificity: 90.1%, 85.9%, and 88.1%). The AUCs of the cSARC-CalF, SARC-CalF, and SARC-F were 0.74 (95% CI, 0.71 - 0.77), 0.79 (95% CI, 0.76 - 0.81), and 0.67 (95% CI, 0.64 - 0.70), respectively. The difference in AUCs between cSARC-CalF and SARC-F and the difference in AUCs between SARC-CalF and SARC-F was statistically significant (p=0.012 and p<0.001, respectively). However, the difference in AUCs between cSARC-CalF and SARC-CalF was not significant (p=0.109). The cSARC-CalF showed a better overall diagnostic accuracy than the SARC-F and a similar overall diagnostic accuracy as the SARC-CalF in Chinese community-dwelling older adults. It may serve as a new tool for screening sarcopenia; however, it needs to be validated in other populations.
