Abstract Objective. To evaluate the relationship between sleep duration, sleep restless and arthritis in middle-aged and older Chinese population. Methods. A total of 4957 middle-aged and elderly people aged 45 years and above from The China Health and Retirement Longitudinal Study (CHARLS) wave 3 were included. Multivariable logistic regression was used to calculate adjusted odds ratios (ORs) and 95 % confidence intervals (CIs) for arthritis. Results. Sleep duration was shown to have a U-shaped association with arthritis after adjusting confounding factors. Compared with <5h sleep duration per night, ORs (95 % CIs) of sleep duration 5-7,7-8 and 8-9 h per night for arthritis were 0.61 (0.52– 0.73, P value <0.001) ,0.47 (0.38-0.58, P value <0.001),0.50 (0.41,0.60, P value <0.001)and 0.50 (0.39–0.64, P value <0.001), respectively. Sleep restless was positively correlated with the prevalence of arthritis. After stratification according to sleep restless status, for those without sleep restless, 8-9 hours duration (OR=0.55, 95 % CI 0.39-0.78,P value=0.001)had the best protective effect on arthritis, while7-8 hours duration (OR=0.45, 95 % CI 0.34-0.60,P value <0.001)was best in people with sleep restless. Conclusion. In middle aged and old Chinese population, sleep duration is U-shaped associated with arthritis, and sleep restless affect the correlation.

Grandchild caregiving is suggested to improve the elderly’s cognitive function, but the specific relationship remains under-investigated. Considering gender disparity, this study aimed to understand the relationship between grandchild caregiving and cognition. In total, 7236 Chinese residents (≥45 years old) were selected from the 2015 China Health and Retirement Longitudinal Study (CHARLS). The China Health and Retirement Longitudinal Study Harmonized Cognitive Assessment Protocol (CHARLS-HCAP) was used to measure cognition. Grandparenting was measured from three dimensions: caregiving frequency, intensity, and the number of grandchildren cared for. The relationship was examined by multivariate linear regression, with age as a moderator. The results showed that the majority of respondents provided care to their grandchildren, especially grandmothers. Grandchild caregiving was positively associated with cognition (β = 0.686, 95% CI = 0.334–1.038), especially in the older-aged group. Moderate, not regular grandparenting, or caring for one grandchild was more positively associated with cognitive function. However, intensive and regular grandchild care was significantly associated with cognition only in men. No moderating effects of age were found in women. The study confirmed that moderate intensity and frequency of caregiving was related to better cognitive function in middle-aged and older Chinese population, whereas cultural context and gender differences could be considered when designing targeted policies.

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.

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.
