Background: China has the largest population living with dementia globally and urban-rural differences are significant in prevalence, risk factors, and health resources. Epidemiologic studies on cognitive impairment in rural areas are limited in China and other low- and middle-income countries. Objective: This study investigated cognitive impairment and associated factors in rural elderly aged 65 years and over in China. Methods: In total, 1,250 participants from ten villages in North China were recruited from June to September, 2017. Face-to-face structured interviews were conducted for data collection. The interviews included socio-demographic information, health status, and psychological assessments. Cognitive function was assessed using the Chinese version of the Mini-Mental State Examination. A multivariate logistic regression model with backward method was employed to identify factors associated with cognitive impairment. Results: The positive rate of cognitive impairment among rural Chinese elderly aged 65 years and older was 42.9% (95% CI, 40.1–45.6). No significant differences were found in cognitive impairment by age or gender before the age of 75 years. Older age, lack of formal school education, reliance on the basic living allowance as the only income source, poor hearing and vision function, diabetes, and activities of daily living dependence were associated with higher rate of cognitive impairment, while tea consumption and fatty liver disease were associated with lower cognitive impairment rate. Conclusion: A very high percentage of rural elderly in China had cognitive impairment. Education programs and prevention interventions targeting modifiable risk factors among high-risk populations should be developed through collective efforts involving all stakeholders.

Aims: To evaluate the prevalence of sleep disturbance in older adults with or without mild cognitive impairment (MCI) and associated factors among residents in rural central China. Methods: A cross-sectional survey was conducted in adults in rural areas of the Hunan province aged≥60 years. Study participants (N = 1213) included 479 individuals meeting the criteria for MCI and 734 with normal cognitive abilities. The participants completed the Athens Insomnia Scale, Stress Resilience Quotient Scale, Affect Balance Scale and Activities of Daily Living (ADL) Scale. Chi-square test, Wilcoxon rank sum analyses and multiple logistic regression were used in this study. Results: A total of 60.33% of participants with MCI demonstrated sleep disturbance (60.33%, 95% CI: 0.559-0.649), which was significantly higher than in the non-MCI group (43.73%, 95% CI: 0.759-0.838). Multiple logistic regression conducted separately in the populations of older adults with or without MCI showed that age, drinking habits, affect balance and activities of daily life were correlates of self-reported sleep disturbance in rural older adults with MCI ( B = −5.469), whereas age, ADL, living arrangement and resilience were the main influencing factors in older adults without MCI ( B = 2.991). Conclusion: Sleep disturbance is more common in older adults with MCI than without MCI in rural areas of China. The factors influencing sleep disturbances vary between older adults with or without MCI, with age and ADL representing common factors influencing sleep disturbance in both groups. Interventions focusing on the age, drinking habits, affect balance and ADL may improve sleep quality in MCI older adults.

Introduction Knowledge about chronic bronchitis (CB) among Aboriginal people in Canada is limited. The aim of this study was to determine the prevalence of CB and its associated factors among Aboriginal people aged 15 years plus. Methods Logistic regression analysis was used on data from the cross-sectional 2006 Aboriginal Peoples Survey to determine risk factors associated with CB. Results CB prevalence was 6.6% among First Nations, 6.2% among Métis and 2.4% among Inuit. Prevalence was higher among females than males (7.2% versus 5.0%). Individuals with CB were more likely to be older, living at a lower income, with a lower educational attainment and residing in rural areas. Smoking status and body mass index were also significantly associated with CB, but their effect differed by sex. Obesity was particularly significantly associated with CB among females compared with males, and current smoking and non-smoking status was significantly associated with CB among females but not males. Conclusion These findings identify factors associated with CB among Aboriginal people. As such, they may represent potentially preventable risk factors that can inform health promotion and disease prevention practices.

Abstract Background Older general hospital patients, particularly those with cognitive impairment, frequently experience adverse events and other care complications during their stay. As these findings have so far been based on small and selected patient samples, the aim of the present study was to provide reliable data on a) the prevalence of adverse care issues (summarized under the term care challenges) in older general hospital patients and on b) associated patient-related risk factors (e.g. cognitive impairment). Methods A cross-sectional representative study comprising 1469 patients aged ≥65 years from 33 randomly selected general hospitals in southern Germany (GHoSt). Data collection included the use of different data sources, e.g. structured interviews with responsible nursing staff concerning care challenges and procedures for determining the patients’ cognitive status. Results Care challenges were statistically significantly (p < 0.001) more often reported for patients with dementia and/or delirium (87.5%) and mild cognitive impairment (47.9%) compared to cognitively unimpaired patients (24.6%). Adjusted odds ratios suggested cognitive impairment, impaired activities of daily living, receiving long-term care and unplanned admission as significant patient-related risk factors for care challenges. Furthermore, the occurrence of such issues was associated with the application of physical restraints, support from relatives, prescription of psycholeptics and specialist consultations. Conclusion The findings suggest a strong impact of different degrees of cognitive impairment on challenges in care. The results might help to design appropriate training programs for hospital staff and other interventions to prevent or reduce critical situations.

Abstract Objective: To estimate the prevalence of mild cognitive impairment (MCI) and its subtypes and investigate the impact of midlife cardiovascular risk factors on late-life MCI among the aging Mexican population. Method: Analyses included a sample of non-demented adults over the age of 55 living in both urban and rural areas of Mexico (N = 1807). MCI diagnosis was assigned based on a comprehensive cognitive assessment assessing the domains of memory, executive functioning, language, and visuospatial ability. The normative sample was selected by means of the robust norms approach. Cognitive impairment was defined by a 1.5-SD cut-off per cognitive domain using normative corrections for age, years of education, and sex. Risk factors included age, education, sex, rurality, depression, insurance status, workforce status, hypertension, diabetes, stroke, and heart disease. Results: The prevalence of amnestic MCI was 5.9%. Other MCI subtypes ranged from 4.2% to 7.7%. MCI with and without memory impairment was associated with older age (OR = 1.01 [1.01, 1.05]; OR = 1.03 [1.01, 1.04], respectively) and residing in rural areas (OR = 1.49 [1.08, 2.06]; OR = 1.35 [1.03, 1.77], respectively). Depression (OR = 1.07 [1.02, 1.12]), diabetes (OR = 1.37 [1.03, 1.82]), and years of education (OR = 0.94 [0.91, 0.97]) were associated with MCI without memory impairment. Midlife CVD increased the odds of MCI in late-life (OR = 1.76 [1.19, 2.59], which was driven by both midlife hypertension and diabetes (OR = 1.70 [1.18, 2.44]; OR = 1.88 [1.19, 2.97], respectively). Conclusions: Older age, depression, low education, rurality, and midlife hypertension and diabetes were associated with higher risk of late-life MCI among older adults in Mexico. Our findings suggest that the causes of cognitive impairment are multifactorial and vary by MCI subtype.

ObjectiveOlder people in rural areas are possibly more frail due to the limited medical resources and lower socioeconomic status. Given the negative healthy outcomes caused by frailty, knowing the epidemiology of frailty in rural areas is of great importance. We tried to synthesise the existing evidences for the prevalence and risk factors of frailty in rural areas.DesignA systematic review and meta-analysis.Data sourcesPubMed, Embase, MEDLINE, Cochrane Library, Web of Science and Scopus were used to identify the articles from inception to 30 April 2019.Eligibility criteriaObservational studies providing cross-sectional data on the prevalence of frailty in rural elderly were extracted.Data extraction and synthesisTwo independent investigators selected studies, extracted data and assessed the methodological quality of included studies. The pool prevalence of frailty was calculated by the random effects model and the OR and 95% CI were used to calculate the risk factors.ResultsThe literature search yielded 2219 articles, of which 23 met the study criteria and were included in this analysis. The pooled prevalence of frailty and pre-frailty were 18% (95% CI 15% to 21%, I2=98.5%, p<0.001) and 50% (95% CI 45% to 56%, I2=98.4%, p<0.001), respectively. The pooled frailty prevalence was 15% for the Fried Phenotype, 18% for the Frailty Index and 23% for other criteria. The pooled prevalence of frailty was 17% for males and 26% for females. The pooled prevalence of frailty was 17% in developing countries and 23% in developed countries. Age, cognitive impairment, depressive symptom, risk of malnutrition, activity of daily living (ADL) disability and poor self-perception of health were associated with frailty. There was no publication bias.ConclusionsFrailty influences almost one in five older people in rural areas, and increasing age, cognitive impairment, depressive symptom, risk of malnutrition, ADL disability and poor self-perception of health were all risk factors for frailty. We should be cautious about the research results due to the heterogeneity between studies.

Abstract Background: To investigate the prevalence of pterygium and associated factors in Han and Mongolian adults at four survey sites in Inner Mongolia, China.Methods: We conducted a population-based, cross-sectional study as part of the China National Health Survey (CNHS). By means of a stratified sampling method, we finally included 2,651 participants of 30 years of age or older from a total of 3,468 eligible residents. Factors associated with pterygium were analysed by a univariate analysis and logistic regression models.Results: The study population included 1,910 Han and 741 Mongolian adults. The mean age±standard deviation of the study cohort was 48.93±11.06 years. The overall prevalence of pterygium was 6.4% (n=169); 1.4% (n=38) of the cases were bilateral and 4.8% (n=128) were unilateral. The most common grade of pterygium was Grade 2. Based on the results of the univariate analysis, eleven factors were included in a multivariate analysis. The results indicated that age (P<0.001), outdoor occupation (P=0.026), and time spent in rural areas (P<0.001) were significantly associated with pterygium. Sex and ethnicity were not identified as risk factors.Conclusions: Our results indicated that outdoor occupation, old age and more time spent in rural areas were risk factors for pterygium in Inner Mongolia. At the same time, town as a survey site (Hohhot and Tsining District) was a protective factor for pterygium. Ethnicity, gender, smoking, diabetes and high blood pressure are not associated with pterygium.Trial registration KEYWORDS: pterygium, prevalence, Han and Mongolian, risk factors, protective factors

And Gender

Elders in rural areas of developing countries are particularly vulnerable to cognitive impairment and gender disparities are notable. Yet, evidence related to gender differences in cognitive impairment in these settings is scarce. This study examined gender differences in cognitive impairment among elderly people aged 65 and above in rural China. A multi-site cross-sectional survey was conducted. In total, 550 males and 700 females were recruited. The Chinese version of the Mini-Mental Status Examination was applied for cognitive impairment screening. Demographic information, lifestyle factors, psychosocial factors, and health-related information were assessed. The prevalence of cognitive impairment was 40.0%in males and 45.1% in females, respectively. Females showed significant higher prevalence after age 75 (62.7% vs. 45.4%, p < 0.005). Older age, hearing impairment, and activities of daily living dependence were common factors associated with cognitive impairment in both females and males. For males, living in a neighborhood with poor social interactions and diabetes were risk factors, while tea consumption was a protective factor. For females, vision impairment and illiteracy were additional risk factors. Individualized interventions and standardized measurements of cognitive function should be developed to suit older populations living in rural and less-developed areas, through collective efforts involving all stakeholders and multidisciplinary teamwork.

Double Incontinence

Fecal and double incontinence are known to be more prevalent among the rural elderly. Yet, there have been few studies on their epidemic condition among Chinese rural elders. This study estimated the prevalence and correlates of fecal and double incontinence in rural elderly aged 65 years and over in North China. A multisite cross-sectional survey was conducted in 10 villages, yielding a sampling frame of 1250 residents. Fecal and urinary incontinence assessments were based on the self-reported bowel health questionnaire and the International Consultation on Incontinence Questionnaire-Short Form, respectively. The concomitant presence of fecal and urinary incontinence in the same subject was defined as double incontinence. The prevalence of fecal and double incontinence was 12.3% and 9.3%, respectively. Factors associated with fecal incontinence included urinary incontinence, lack of social interaction, traumatic brain injury, cerebrovascular disease, and poverty. Physical activities of daily living dependence, traumatic brain injury, lack of social interaction, and poor sleep quality were associated with higher odds of having double incontinence, whereas tea consumption was correlated with lower odds. Individualized intervention programs should be developed targeting associated factors and high-risk populations. These intervention programs should be integrated into existing public health services for the rural elderly to facilitate appropriate prevention and management of incontinence.
