The relationship between physical activity (PA) and the risk of frailty has not reached a conclusive result. This systematic review with meta-analysis aimed to evaluate the effect of PA on the onset ...of frailty in the community-dwelling middle and older age adults by pooling data from cohort studies.
A systematic literature search was performed via PubMed, Embase, and Web of Science up to June 01, 2021. Pooled adjusted effect estimates (ES) with 95% confidence interval (CI) were calculated by using the random-effect model and by comparing the highest with lowest levels of PA. Heterogeneity was tested using the I2 statistic and Q-test. The quality of evidence was evaluated by using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
A total of ten cohort studies with 14 records were selected, and the GRADE approach classified the quality of evidence as low. In comparison with the lowest level of PA, the highest level of PA was associated with 41% decreased odds of frailty (ES: 0.59, 95% CI: 0.51-0.67; I2 = 70.0%, P-heterogeneity < 0.001) after pooling results from included studies. In stratified analysis by frailty assessment approach, the highest level of PA was significantly associated with 37% (ES 0.63, 95% CI: 0.52-0.77, 49% (ES: 0.51, 95% CI: 0.41-0.63), and 30% (ES: 0.70, 95% CI: 0.65-0.75) reduced odds of frailty when pooling studies using criteria of physical frailty, multidimensional model, and accumulation of disability, respectively. Stratified analyses further by PA indicators and PA assessment tools yielded similar protective effects in any subgroups.
This study with moderate-certainty evidence shows that a higher level of PA was associated with lower odds of frailty, and the benefits of PA for frailty prevention were independent of frailty assessment tools, PA indicators, and PA assessment methods. Findings from this study may help implement active exercise strategies to prevent frailty.

Evidence on the association between adverse childhood experiences (ACEs) and handgrip strength (HGS) in later life was limited and inconclusive. We aimed to explore the impact of ACEs on HGS among ...middle-aged and older Chinese adults.
We conducted a cross-sectional study with data extracted from the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey with respondents recruited from 450 villages/urban communities of 28 provinces. Participants aged 45 years or older were drawn from the CHARLS 2014 life history survey and the 2015 health survey. Twelve ACE indicators before the age of 17 years were collected. HGS was measured with a dynamometer and the maximum value of HGS obtained from both hands was used in the analyses. Low muscle strength (LMS) was defined according to the recommendation of European Working Group on Sarcopenia in Older People (EWGSOP). Multivariate linear and logistic regression models were constructed to evaluate the association of ACEs with continuous HGS and LMS, with adjustment for age, sex, marital status, ethnicity, area of residence, smoking and drinking status, body mass index, hypertension, dyslipidaemia, diabetes mellitus, cardiovascular disease, arthritis, hip fracture, and memory-related disease.
Of the 7209 eligible participants, 2258 (31.3%) had experienced three or more ACEs. Compared to individuals without ACEs, exposure to ≥ 3 ACEs was negatively associated with continuous HGS in kilogram (β = -0.93, 95% CI: -1.37, -0.49) and positively associated with the risk of LMS (OR = 1.34, 95% CI: 1.12, 1.61). Such associations were consistently found both in men and women who had experienced three or more ACEs. Significant dose-response relationship between the number of ACEs and outcomes was also observed in the overall population and different sex groups.
Exposure to ACEs was associated with lower HGS and increased risk of LMS among middle-aged and older Chinese adults, indicating the importance of intervention in individuals with experience of ACEs in order to mitigate its detrimental impact on HGS and promote healthy ageing.
ABSTRACT
Aims/Introduction
The cardiometabolic index (CMI) has been proposed as a novel indicator of cardiometabolic status. This study aimed to investigate the effects of CMI and its longitudinal ...transitions on the development of type 2 diabetes mellitus in middle‐aged and older Chinese.
Materials and Methods
We used data from the China Health and Retirement Longitudinal Study (2011–2018). CMI was calculated as the product of the waist circumference to height ratio and the triglyceride to high‐density lipoprotein cholesterol ratio. At baseline in 2011, the subjects were classified into low‐ and high‐CMI groups, and then divided into four transition patterns during follow‐up, i.e. maintained‐low, low‐to‐high, high‐to‐low, and maintained‐high CMI. The hazard ratios (HRs) of different transition patterns for type 2 diabetes mellitus were calculated using multivariable Cox frailty models.
Results
During 2011–2018, 7,347 participants were included. Participants with a high‐CMI at baseline had a significantly higher risk of new‐onset type 2 diabetes mellitus than those with a low‐CMI (HR = 1.78, 95% CI:1.55–2.05). For subjects with a low‐CMI at baseline, the risk of developing type 2 diabetes mellitus increased by 75% if their CMI status changed to high during follow‐up (HRlow‐to‐high = 1.75, 95% CI:1.35–2.28). Meanwhile, for subjects with a maintained‐high CMI, no significant risk reduction for type 2 diabetes mellitus was found when their CMI changed to low status (HRhigh‐to‐low = 0.77, 95% CI: 0.58–1.01).
Conclusions
Baseline CMI levels and longitudinal CMI transition patterns were associated with a higher risk of type 2 diabetes mellitus. Early anti‐lipid measures should be taken to prevent type 2 diabetes mellitus in middle‐aged and older Chinese.
Our study demonstrated that high CMI was a detrimental factor of new‐onset type 2 diabetes mellitus. Additionally, there were significant associations between transitions of CMI status and type 2 diabetes mellitus. For better prevention of type 2 diabetes mellitus, health workers should devote more attention to the general healthy population, and take measures to prevent their CMI progressing from low to high levels. The value of CMI as a reliable and efficient indicator of the early prevention of type 2 diabetes mellitus should be further investigated.
With childhood hypertension emerging as a global public health concern, understanding its associated factors is crucial. This study investigated the prevalence and associated factors of hypertension ...among Chinese children. This cross-sectional investigation was conducted in Pinghu, Zhejiang province, involving 2,373 children aged 8-14 years from 12 schools. Anthropometric measurements were taken by trained staff. Blood pressure (BP) was measured in three separate occasions, with an interval of at least two weeks. Childhood hypertension was defined as systolic blood pressure (SBP) and/or diastolic blood pressure (DBP) greater than or equal to age-, sex-, and height-specific 95th percentile, across all three visits. A self-administered questionnaire was utilized to collect demographic, socioeconomic, health behavioral, and parental information at the first visit of BP measurement. Random forest (RF) and multivariable logistic regression model were used collectively to identify associated factors. Additionally, population attributable fractions (PAFs) were calculated. The prevalence of childhood hypertension was 5.0% (95% confidence interval CI: 4.1-5.9%). Children with body mass index (BMI) greater than or equal to 85th percentile were grouped into abnormal weight, and those with waist circumference (WC) > 90th percentile were sorted into central obesity. Normal weight with central obesity (NWCO, adjusted odds ratio aOR = 5.04, 95% CI: 1.96-12.98), abnormal weight with no central obesity (AWNCO, aOR = 4.60, 95% CI: 2.57-8.21), and abnormal weight with central obesity (AWCO, aOR = 9.94, 95% CI: 6.06-16.32) were associated with an increased risk of childhood hypertension. Childhood hypertension was attributable to AWCO mostly (PAF: 0.64, 95% CI: 0.50-0.75), followed by AWNCO (PAF: 0.34, 95% CI: 0.19-0.51), and NWCO (PAF: 0.13, 95% CI: 0.03-0.30). Our results indicated that obesity phenotype is associated with childhood hypertension, and the role of weight management could serve as potential target for intervention.

Adverse childhood experiences (ACEs) might be associated with maternal spontaneous fetal loss, while evidence among Chinese population is limited. This study aims to explore the associations of ...adverse childhood experiences (ACEs) among women and their spouses with the risk of spontaneous abortion and stillbirth.
Data were from the China Health and Retirement Longitudinal Study (CHARLS) 2014 survey. ACEs were categorized into intra-familial ACEs and extra-familial ACEs. The associations of maternal and paternal ACEs with women's history of spontaneous abortion and stillbirth were investigated by logistic regression.
7,742 women were included with 9.05% and 2.47% experiencing at least one spontaneous abortion or stillbirth, respectively. Women exposed to 2, 3, and ≥ 4 ACEs were at significantly higher odds of spontaneous abortion, with adjusted odds ratios (ORs) of 1.52 (95% CI, Confidence Interval 1.10-2.10), 1.50 (95% CI 1.07-2.09) and 1.68 (95% CI 1.21-2.32), respectively. A significant association between ≥ 4 maternal intra-familial ACEs and stillbirth (OR 2.23, 95% CI 1.12-4.42) was also revealed. Furthermore, paternal exposures to 3 and ≥ 4 overall ACEs were significantly associated with their wives' history of spontaneous abortion, with adjusted ORs of 1.81 (95% CI 1.01-3.26) and 1.83 (95% CI 1.03-3.25), respectively.
Both maternal and paternal ACEs were associated with spontaneous abortion, and potential mediators might need to be considered to further explore impacts of maternal and paternal ACEs on maternal reproductive health.

General and central obesity are suggested to be associated with elevated blood pressure (BP), whereas few studies have investigated their combined associations with hypertension in children. This ...study aimed to assess the associations of combinations of general obesity and central obesity with hypertension in Chinese children, including its stages and phenotypes. A total of 5430 children aged 7-17 years in Zhejiang Province were enrolled. General obesity was evaluated by body mass index (BMI), while central obesity was by waist circumference (WC). Then all children were sorted into three mutually exclusive groups: normal weight with or with no central obesity (NW), abnormal weight with no central obesity (AWNCO), and abnormal weight with central obesity (AWCO). Hypertension was defined as either a systolic or diastolic BP ≥ 95th percentile, and further classified into stage 1 hypertension, stage 2 hypertension, isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), and systolic diastolic hypertension (SDH). Logistic regression was used. AWNCO and AWCO were associated with stage 1 hypertension (AWNCO, odds ratio OR = 1.94, 95% confidence interval CI: 1.59-2.37; AWCO, 2.67, 2.20-3.25), stage 2 hypertension (AWNCO, 2.35, 1.33-4.13; AWCO, 4.53, 2.79-7.37), ISH (AWNCO, 2.50, 1.96-3.18; AWCO, 3.95, 3.15-4.95), and SDH (AWNCO, 2.48, 1.75-3.52; AWCO, 2.78, 1.94-3.99). Children with AWCO were more likely to have stage 1 and stage 2 hypertension, as well as ISH and SDH. The combined measurement of general and central obesity is suggested as an appropriate screening tool for hypertension among children and adolescents.
To assess the associations of the triglyceride and glucose (TyG) index with hypertension stages, phenotypes, and their progressions.
The data originated from the China Health and Retirement ...Longitudinal Study. Multinomial logistic regression investigated the associations of the TyG index with hypertension stages (stage 1, stage 2), phenotypes (isolated systolic hypertension ISH, isolated diastolic hypertension IDH, systolic diastolic hypertension SDH), their progressions.
Compared with the lowest quartile of TyG index, the highest quartile was associated with increased risks of stage 1 hypertension (OR 1.71, 95% CI 1.38-2.13), stage 2 (1.74, 1.27-2.38), ISH (1.66, 1.31-2.11), IDH (2.52, 1.26-5.05), and SDH (1.65, 1.23-2.23). Similar results were found when TyG index was a continuous variable. From 2011 to 2015, a higher baseline TyG index was associated with normotension to stage 1 (per-unit: 1.39, 1.16-1.65), normotension to ISH (per-unit: 1.28, 1.04-1.56), and normotension to IDH (per-unit: 1.94, 1.27-2.97).
The TyG index was associated with different hypertension stages, phenotypes, their progressions, and could be served as a surrogate indicator for early hypertension management.
BackgroundRestless legs syndrome (RLS) is a prevalent neuro-sensory disorder that impairs quality of life. In this systematic review and modelling study, we estimated the global and regional ...prevalence of RLS and its associated factors.MethodsWe searched PubMed, Embase, and Medline for population-based studies on RLS prevalence published up to 12 November 2023. The included studies reported prevalence using the International Restless Leg Syndrome Study Group's (IRLSSG) minimal diagnostic criteria without limitations on frequency, duration, or severity. We applied a multilevel multivariable mixed-effects meta-regression to generate the age-specific and sex-specific prevalence of RLS for high socio-demographic index (H-SDI) and low and middle socio-demographic index (LM-SDI) regions. We pooled odds ratios (ORs) for RLS associated factors using random-effects models. Finally, we derived the regional prevalence and cases of RLS based on an associated factor-based model.ResultsFrom 52 articles across 23 countries, the global RLS prevalence in 2019 was estimated to be 7.12% (95% confidence interval (CI) = 5.15–9.76) among adults 20–79 years of age, equating to 356.07 million (95% CI = 257.61–488.09) affected individuals. Prevalence was similar in H-SDI (7.29%; 95% CI = 5.04–10.41) and LM-SDI (7.10%; 95% CI = 5.16–9.70) regions, with the majority of cases in LM-SDI countries (323.06 million; 90.73%). Europe had the highest (7.60%; 95% CI = 5.44–10.52) and Africa the lowest regional prevalence (6.48%; 95% CI = 4.70–8.87). The Western Pacific Region, meanwhile, had the most cases (111.91 million; 95% CI = 80.93–153.42). Factors positively associated with RLS included advanced age (OR = 1.13; 95% CI = 1.04–1.24), smoking (OR = 1.46; 95% CI = 1.29–1.64), depression (OR = 1.71; 95% CI = 1.26–2.32), and diabetes (OR = 1.54; 95% CI = 1.19–1.97).ConclusionsA considerable global burden of RLS exists. Effective strategies are needed to increase awareness and optimise resource allocation to address this often-overlooked condition. High-quality epidemiological investigations employing standardised and rigorous criteria for RLS are essential for addressing RLS burden more effectively.RegistrationPROSPERO: CRD42020161860.
