Abstract Background: Peak expiratory flow (PEF), as an essential index used for screening and monitoring asthma, chronic obstructive pulmonary disease, and respiratory mortality especially in elderly, is recommended especially for low resource settings in low- and middle-income countries. However, few reports have focused on the reference of PEF in China, especially in the middle-aged and elderly. Thus, the aim of this study was to determine age- and sex-specific reference values of PEF in the middle-aged and older Chinese population.Methods: There were 11,717 participants included for reference value analysis and 11,340 participants were included for risk factor analysis. The PEF was measured using a peak flow meter in L/min. The distribution of PEF terciles stratified by sex and age were reported. Multiple linear regression analysis was used to determine the associations between risk factors and PEF.Results: The PEF was higher in men than women across all age subgroups. The value of PEF decreased with age in both men and women. Height, weight, handgrip strength, and household air pollution were positively associated with PEF, and age, waist circumference smoking status were negatively associated with PEF significantly in both men and women (all P <0.05). The mean values were 9.38 L/min and 64.12 L/min for men and women. Meanwhile, the prevalence of low PEF was 1.62% and 2.16% for men and women, respectively.Conclusions: Age- and sex-specific centiles of PEF for the middle-aged and older Chinese population were estimated. The reference values for low PEF were provided for epidemiological studies and clinical practice in the future. Interventions on lung function or respiratory disease should be pay more attention on factors associated with PEF.

However, few studies have focused on the reference of PEF in China, especially in middle-aged and elderly people. Thus, this study aimed to determine age- and sex-specific reference values of PEF in the middle-aged and elderly Chinese population.Methods: There were 8,914 participants who were included for risk factor analysis and 5,498 participants included for reference value analysis. The PEF was measured using a peak flow meter in liters per minute. The distributions of standardized PEF terciles stratified by sex and age were reported. Multiple linear regression analysis was used to determine the associations between risk factors and PEF.Results: The PEF was higher in men than women across all age subgroups. The value of PEF decreased with age in both men and women. Height, weight, handgrip strength, and residence in rural were positively associated with PEF. Age and smoking status were negatively associated with PEF significantly in both men and women (P &lt; 0.05). The mean PEF values were 367.10 and 253.00 L/min for men and women, respectively. Meanwhile, the prevalence of low PEF was 3.94 and 3.32% for men and women, respectively.Conclusions: Age- and sex-specific centiles of standardized PEF for the middle-aged and elderly Chinese population were estimated. The reference values for low PEF could provide reference standards for epidemiological studies and clinical practices in the future. Interventions to improve lung functions or to prevent respiratory disease should be paid more attention to factors associated with PEF.

Abstract Background: With the aggravation of social competition and work burden pressure, the health condition of the middle-aged and above population in China has declined significantly. Frailty can be used as a criterion for evaluating a person's unhealthy state. However, there is limited data on the prevalence and related factors of frail status in Chinese middle-aged and older people.The objective of this study was to explore the correlation between frail status, chronic diseases, abnormal physical examination indicators among middle-aged and older populations.Methods: Participants were 9,985 community-dwelling adults over the age of 40 years living in China. Data were from the 2015 China Health and Retirement Longitudinal Survey which was a nationally representative sample and frailty phenotype was based on Fried frailty criteria. We analyzed the demographics of participants and multivariate-adjusted related factors for frail and pre-frail population.Results: The overall prevalence of frailty and pre-frailty was 3.1% (95% CI: 2.8, 3.5) and 53.66% (95% CI: 52.7, 54.6) among the general Chinese population aged 40 years or older. Hypertension (OR: 1.8, 95% CI: 1.3, 2.593), pain (OR: 1.8, 95% CI: 1.3, 2.5), and hip fracture (OR: 2.2, 95% CI: 1.1, 4.4) were associated with prevalent frailty. Relative factors for frailty also included increased cystatin C (OR: 4.5, 95% CI: 3.0, 6.7) and glycated hemoglobin (OR: 1.2, 95% CI: 1.1, 1.4), as well as decreased peak expiratory flow (OR: 0.993, 95% CI: 0.991, 0.994).Conclusions: Fried-defined frailty and pre-frailty are highly prevalent in the Chinese population over 40 years older. Hypertension, pain, hip fracture, low education, and underweight are major related factors for frailty. The decrease in peak expiratory flow and the increase in cystatin C and glycated hemoglobin are good indicators for detecting frailty. Thus, frailty is an increasingly common condition and will become a major important health issue for people over middle age.

The Impact

Introduction: Previous studies have suggested that sensory loss is linked to falls. However, most of these studies were cross-sectional designed, focused on single sensory loss, and were conducted in developed countries with mixed results. The current study aims to investigate the longitudinal relationship between hearing loss (HL), vision loss (VL) and dual sensory loss (DSL) with falls among middle-aged and older Chinese population over 7 years.Methods: The data was obtained from the China Health and Retirement Longitudinal Survey (CHARLS). In total, 7,623 Chinese older adults aged over 45 were included at baseline 2011 in this study. Self-reported falls and HL/VL/DSL were accepted. Other confounding variables included age, sex, BMI, educational level, marital status, various physical disorders and lifestyles. The impact of baseline sensory status on baseline prevalence of falls and incident falls over 7 years were assessed using logistic regression analyses. A logistic mixed model was used to assess the association between time-varying sensory loss with incident falls over 7 years after adjusted with multi-confounding factors.Results: Single and dual sensory loss groups had significantly higher prevalence of falls compared to no sensory loss (NSL) group (DSL: 22.4%, HL: 17.4%, VL: 15.7%, NSL: 12.3%). Baseline HL (OR: 1.503, 95% CI: 1.240–1.820), VL (OR: 1.330, 95% CI: 1.075–1.646) and DSL (OR: 2.061, 95% CI: 1.768–2.404) were significantly associated with prevalence of falls. For longitudinal observation over 7 years, baseline HL/DSL and persistence of all types of sensory loss were associated with incidence of falls. Time-varying HL (OR: 1.203, 95% CI: 1.070–1.354) and DSL (OR: 1.479, 95% CI: 1.343–1.629) were associated with incident falls after adjusted with multi-confounders, while VL was not.Conclusion: HL and DSL are significantly associated with both onset and increased incidence of falls over 7 year's observation in middle-aged and elderly Chinese population. Persistence or amelioration of sensory loss status could exert divergent influences on incidence of falls, which should be considered in the development of falls-prevention public health policies for aging population.

Expiratory Flow

Background: Data on peak expiratory flow rate (PEFR) for Madurai district, Tamil Nadu, India, school children is not available. Hence, this study aims to construct predicted equations for PEFR in both sexes in the age group of 5 - 12 years according to the height as a reference.Methods: About 961 healthy children (493 boys and 468 girls) were randomly selected from six schools of Madurai district. PEFR readings were repeated thrice and the  highest value of these 3 readings was taken as the observed PEFR. Linear regression analysis was performed using age, weight, height and body surface area (BSA) as independent variables and PEFR as the dependent variable.Results: Statistical correlation is found between height, age, BSA, weight and PEFR in both sexes. The variables which show significant positive relationship with PEFR are height (r=0.78), age (r=0.74), BSA (r=0.73), weight(r=0.67) of which height shows the most significant correlation. The regression equation for PEFR with height is: boys: PEFR =3.12 x (height)-211.85, girls: PEFR = 3.07 x (height)- 212.3.Conclusions: BSA needs further formula-based calculation and age may be falsely given in the school records or may be forgotten by uneducated parents. Weight is having less correlation coefficient compared to other parameters. So, this study recommends deriving predicted equation for PEFR based on height for both genders. The prediction equations for PEFR obtained in this study can be used as local reference for the follow up of children with respiratory disorders in and around Madurai district, Tamil Nadu, India.
