Abstract Background: Asthma is one of the most prevalent chronic respiratory disease worldwide. The survey aims to describe the updated prevalence and risk factors of asthma among individuals aged 45 and older in mainland China. Methods: The data for this study come from the fourth wave of China Health and Retirement Longitudinal Study (CHARLS) conducted by the National School of Development of Peking University in 2018. CHARLS is a nationally representative survey targeting populations aged 45 and over from 28 provinces/cities in mainland China. A representative sample of 19816 participants were recruited for the study using a multi-stage stratified sampling method. The prevalence of asthma was described across different characteristics. The potentially risk factors were examined by multivariable logistic regressions. Results: A total of 18504 participants (8759 men and 9745 women) were eligible for the final data analysis. The estimated prevalence of asthma among Chinese people age≥ 45 years in 2018 was 2.16% (95%CI 1.96-2.38). The prevalence of asthma significantly differs according to race (P=0.002), with an overall rate of 2.06% (95% CI 1.86-2.29) in Han and 3.28% (95%CI 2.47-4.34) in minorities. Furthermore, the minorities (OR=1.54 [95% CI 1.114-2.122], P=0.009), elderly people (60-69 years group: OR= 2.65 [95% CI 1.230-5.702], P=0.013; ≥ 70 years group: OR=3.38 [95% CI 1.741-8.036], P=0.001), middle-school education and below (middle-school education: OR=1.91[95%CI: 0.678-1.193], P=0.009; primary education: OR=2.59 [95% CI 0.675- 1.199], P< 0.001; literate: OR=2.60 [95% Cl 0.480- 0.928; illiterate: OR=2.89 [95% CI 0.220-0.572]), smokers (OR=1.36 [95% CI 1.109-1.677], P=0.003), North (OR=1.51[95% CI 1.02-2.078], P=0.01) or Northwest China residence (OR=1.70 [95% CI 1.170-2.472], P=0.005) were associated with prevalent asthma. Conclusions: Asthma is prevalent but underappreciated among middle-aged and elderly people in China. A number of risk factors were identified. These results can help to formulate correct prevention and treatment measures for asthma.

ABSTRACT CONTEXT AND OBJECTIVE: Identification of frailty syndrome and its relationship with cardiovascular risk factors among hospitalized elderly people is important, since this may contribute towards broadening of knowledge regarding this association within tertiary-level services. This study aimed to evaluate the cardiovascular risk factors associated with frailty syndrome among hospitalized elderly people. DESIGN AND SETTING: Observational cross-sectional study in a public teaching hospital. METHODS: The participants were elderly patients admitted to clinical and surgical wards. The cardiovascular risk factors assessed were: body mass index (BMI), waist circumference, systemic arterial hypertension (SAH), blood glucose, total cholesterol, high-density lipoproteins (HDL), low-density lipoproteins (LDL) and triglycerides. To identify frailty syndrome, the method proposed by Fried was used. The data were analyzed through descriptive statistics, chi-square test (P < 0.10) and multinomial logistic regression (P < 0.05). RESULTS: A total of 205 individuals were evaluated. It was found that 26.3% (n = 54) of the elderly people were frail, 51.7% (n = 106) were pre-frail and 22% (n = 45) were non-frail. The preliminary bivariate analysis (P < 0.10) for the regression model showed that frailty was associated with BMI (P = 0.016), LDL cholesterol (P = 0.028) and triglycerides (P = 0.093). However, in the final multivariate model, only overweight remained associated with the pre-frail condition (odds ratio, OR = 0.44; 95% confidence interval, CI = 0.20-0.98; P = 0.045). CONCLUSION: States of frailty were highly present in the hospital environment. The pre-frail condition was inversely associated with overweight.

Abstract Frailty is characterized as a set of factors related to the body structure that lead the subject to a process of physical vulnerability, increasing their dependence. The study aims to investigate the aggregation of factors related to physical frailty (PF) in elderly residents of a city with a low Human Development Index (HDI). This is a cross-sectional study carried out in the city of Ibicuí, state of Bahia, Brazil, and including a random 270 elderly people aged ≥ 60 years. The physical frailty condition was identified according to the criteria proposed by Fried and collaborators. In the data analysis, descriptive statistics, cluster analysis, and multinominal logistic regression procedures were used. The highest prevalence of aggregation was identified when the four risk factors were combined: weight loss, strength, walking speed and physical activity levels (O/E = 4.36; CI = 4.04 - 4.68). It was identified that older people (80 years old or more) with a lower level of education (unlettered) were more likely to have three or more risk factors for physical frailty (p <0.05). As for sociodemographic variables, those who were older and had lower levels of education were more likely to have three or more risk factors. The development of actions that encourage a healthier lifestyle to favor the prevention and treatment of physical frailty, as well as to increase health literacy and knowledge, may reduce the problems related to this condition in older adults, mainly thinking about the next generations.

The Difference

Background: We would like to investigate the prevalence trend, potential risk factors and geographic features of reduced visual acuity (VA) in primary and secondary schoolchildren of Hong Kong. Methods: This was a serial cross-sectional study using historical data of schoolchildren aged 6 to 15 years from the annual health checks conducted at Student Health Service Centers across Hong Kong, for the school years of 2000/2001 to 2016/2017. Results: The prevalence of reduced VA increased from 49.23% (95% CI, 48.99−49.47) in 2000/2001 to 54.34% (95% CI, 54.10−54.58) in 2011/2012 but decreased to 51.42% (95% CI, 51.17−51.66) in 2016/2017. Girls were less susceptible than boys at age 6−7 (and in grade primary 1−2), but more susceptible at older ages. The prevalence in junior grades increased while the risk effect of grade reduced over the past 17 years. Geographic variation on the risk for reduced VA existed and spatial autocorrelation was positive. The difference in prevalence of reduced VA between Hong Kong and mainland China has decreased in recent years. Cross-border students living in mainland China were associated with a lower risk for reduced VA. Conclusions: Further study was proposed to investigate the environmental association between students living in and outside Hong Kong with the prevalence of reduced VA. Multi-level research should also be conducted to investigate the influence of compositional and contextual factors on the prevalence of reduced VA.

Epidemiological Characteristics

Background: Frailty is a common syndrome in elderly people, but has not been fully studied in China. We aimed to investigate the epidemiological characteristics of frailty and analyze its risk factors in elderly people in rural areas of China. Methods: This cross-sectional study was conducted between September and October 2016. Overall, 4323 elderly people over 60 yr were enrolled by cluster random sampling method from the Fengxian District of Shanghai, China. These subjects voluntarily participated in the health examination of the 2016 National Basic Public Health Service Program. In addition to regular examination items, frailty assessment was performed on the basis of Fried frailty phenotype criteria. Results: The prevalence of pre-frailty and frailty was 49.4% and 6.8%, respectively. Advanced age (OR=1.44 for pre-frailty and OR=2.01 for frailty, 65-74 years old; OR=3.02 for pre-frailty and OR=14.13 for frailty,75-84 years old; OR=8.17 for pre-frailty and OR=71.71 for frailty, ≥85 years old), female (OR=1.32 for pre-frailty and OR=1.97 for frailty), stroke history (OR=1.75 for pre-frailty and OR=2.43 for frailty), vision decrease (OR=1.98 for pre-frailty and OR=2.70 for frailty), and anemia (OR=1.95 for pre-frailty and OR=3.64 for frailty) were common risk factors for both pre-frailty and frailty. Conclusion: Healthy elderly people in the rural areas of Shanghai have relatively high prevalence of pre-frailty and frailty. Advanced age, female, stroke history, decreased vision, and anemia are the risk factors for pre-frailty and frailty.
