RESUMO
BACKGROUND: Drowning is an important contributor to the burden of deaths in China. Exposure to open water is a risk factor for drowning, but few studies quantify its impact on drowning. The purpose of this study was to provide an up-to-date analysis of unintentional drowning in China, including impact of exposure to open water. METHODS: Chinese provincial data from the Global Burden of Disease Study 2019 were used to describe the burden of unintentional drowning in 33 provinces and changes from 1990 to 2019. Provincial outdoor open water resource data were used to explore the relationship between outdoor open water resources and drowning burden using K-median clustering analysis. RESULTS: Between 1990 and 2019, the unintentional drowning incidence, mortality and disability adjusted life years (DALY) rates declined by 31.2%, 68.6% and 74.9%, respectively, with differences by age, sex and province. In 2019, the DALY rate for drowning was relatively higher in children under 20 year, the elderly over 80 years than other age groups and was relatively higher in men. There was no statistical difference in overall incidence rate by sex. Provincial differences in unintentional drowning burden show a positive relationship with the availability and size of outdoor open water. CONCLUSIONS: As expected availability of water increases drowning risk. There is a need to address drowning environmental risk especially among children and the elderly. Localised water safety plans which consider drowning burden and environmental risk factors are needed in China to ensure a sustained decline of unintentional drowning.
RESUMO
There has been limited examination of child road injury policies. This study aims to systematically characterize national policies relevant to child road safety in China over the past two decades and identify potential gaps based on the WHO child road safety framework. As a scoping review, this study searched for national policies for child road safety on the websites of government agencies. A total of 22,487 policies were searched, of which 103 policies issued by 37 institutions, were included in the analysis, including 12 policies jointly developed by multiple agencies. Mapping identified policies to strategies in the WHO framework, most WHO strategies requiring legislation were found to be in place in China and to fully meet the intent of the WHO recommendation. The single exception was in the area of child restraints which was deemed to not be fully covered due to a lack of eligible policies on enforcement of child restraint use laws. Two strategies requiring standards were fully covered; eight strategies requiring policy support were partially or not covered, mainly related to equipping emergency vehicles with child-appropriate medical equipment. Enhancing school bus safety was identified as a policy focus area in China beyond those recommended by the WHO framework. This study identified three areas for improvement: (1) strengthening road safety policies targeting children, (2) strengthening enforcement of legislation, e.g., child restraint use, and (3) increasing multiple-sector cooperation on policy formulation.

RESUMO
Previous studies have demonstrated health impacts of climate change, but evidence on heatwaves' associations with road traffic injury (RTI) is limited. In this study, individual information of RTI cases in May-September during 2006-2021 in China were obtained from the National Injury Surveillance System. Daily maximum temperatures (TMmax) during 2006-2021 were collected from the ERA-5 reanalysis, and the projected daily TMmax during 2020-2099 were obtained from the latest Coupled Model Intercomparison Project Phase 6 Shared Socioeconomic Pathways scenarios (SSPs). We used a time-stratified case-crossover analysis to investigate the association between short-term exposure (lag01 days) to heatwaves (exceeding the 92.5th percentile of daily TMmax for ≥ three consecutive days) and RTI, and to project heatwave-related RTI until 2099 across China. Finally, a total of 1 031 082 RTI cases were included in the analyses. Compared with non-heatwaves, the risks of RTI increased by 3.61 % during heatwaves. Greater associations were found in people aged 15-64 years, in people with transportation occupation, for non-motor traffic vehicle injuries, for severe RTI cases, and in Western China particularly in Qinghai province. We projected substantial increases in attributable fraction (AF) of heatwave-related RTI in the future, particularly in Western and Southwest China. The national average increase in AF (per decade) during 2020s-2090s was 0.036 % for SSP1-2.6 scenario, and 0.267 % for SSP5-8.5 scenario. This study provided evidence on the associations of heatwaves with RTI, and the heatwave-related RTI will substantially increase in the future.

Although studies have explored the relationship between temperature and CO poisoning, the results are not consistent, and there is still a lack of early warning criteria of temperature related to CO poisoning. In order to comprehensively study the exposure-response relationship between daily average temperature and CO poisoning, and to further explore the early warning criteria of temperature related to CO poisoning, we used daily cases of CO poisoning in 31 National Injury Surveillance System (NISS) surveillance sites in seven administrative geographical regions of China and daily meteorological data obtained from the China Meteorological Science Data Sharing Service Platform from 2009 to 2019 to do the analysis. Daily meteorological data of 698 weather stations across China were interpolated at a 0.01° × 0.01°spatial resolution, which were then applied to extract the daily meteorological data of all included NISS sites. The Distributed Lag Non-linear Model (DLNM) model was applied to estimate the exposure-response associations (relative risk, RR) of daily mean temperature with CO poisoning, which was then further used to identify early warning criteria of temperature related to CO poisoning. A total of 10,618 CO poisoning cases were included in this study, with an average of 0.4 cases per day. There was generally a reverse J-shaped association between temperature and CO poisoning risk, indicating that both low and high temperature may increase the risk of CO poisoning, but low temperature usually has a longer lagged effects than high temperature. Spatialy, the exposure-response associations between temperatue and CO poisoning largely varied among regions, with greater effects of low temperatures in Southern China than in Northern China. The cumulative effects (RR, lag0-6 days) of 10 % percentile temperature ranged from 1.13 (95%CI: 1.01,1.26) in East China to 1.73 (95%CI:1.63,1.83) in South China. We also observed significant spatial variations in the early warning criteria of temperature related to CO poisoning across China. However, the patterns of high temperature effects on CO poisoning and the warning criteria of high temperature were mixed across China. In conclusions, both low temperature and high temperature may increase the risk of CO poisoning in China, and the effect of low temperature is more obvious, especially in South China, Northeast China, and North China. In addition, there is an urgent need to establish air temperature early warning and grading criteria for CO poisoning in different areas of China.
RESUMO
BACKGROUND: Chinese National Essential Public Health Service Package (NEPHSP) has mandated primary health care providers to provide falls prevention for community-dwelling older people. But no implementation framework is available to guide better integration of falls prevention for older people within the primary health care system. METHODS: This is a two-stage online participatory design study consisting of eight workshops with stakeholders from three purposively selected cities. First, two workshops were organised at each study site to jointly develop the framework prototype. Second, to refine, optimise and finalise the prototype via two workshops with all study participants. Data analysis and synthesis occurred concurrently with data collection, supported by Tencent Cloud Meeting software. RESULTS: All participants confirmed that the integration of falls prevention for older people within the NEPHSP was weak and reached a consensus on five opportunities to better integrate falls prevention, including workforce training, community health promotion, health check-ups, health education and scheduled follow-up, during the delivery of NEPHSP. Three regional-tailored prototypes were then jointly developed and further synthesised into a generic implementation framework by researchers and end-users. Guided by this framework, 11 implementation strategies were co-developed under five themes. CONCLUSIONS: The current integration of falls prevention in the NEPHSP is weak. Five opportunities for integrating falls prevention in the NEPHSP and a five-themed implementation framework with strategies are co-identified and developed, using a participatory design approach. These findings may also provide other regions or countries, facing similar challenges, with insights for promoting falls prevention for older people.
KEYPOINTS: The integration of falls prevention for older people was weak in the Chinese PHC system.Five opportunities were identified for better integrating falls prevention for older people in the Chinese PHC system.We developed an implementation framework to strengthen the solid integration of falls prevention in the Chinese PHC system.

What is already known about this topic?: Many of the current studies focusing on fall prevention interventions have been conducted in hospital settings within a select few urban areas in China, thus yielding limited evidence on the effectiveness of large-scale, multicenter, community-based interventions. What is added by this report?: In comparison to the control group, participants in the intervention group exhibited a 64% reduction in fall risk. Group-based fall prevention programs have demonstrated efficacy in mitigating fall risk among the elderly population. What are the implications for public health practice?: Group-based fall prevention interventions serve as a significant adjunctive resource for the management of elderly health within communities and offer compelling evidence to support the incorporation of fall prevention strategies into health policy frameworks in China.
RESUMO
What is already known about this topic?: Poisoning constitutes a significant cause of mortality among individuals aged 1 to 44 in China. Nonetheless, the epidemiological understanding of poisoning incidents within emergency departments remains fragmented across the region. What is added by this report?: In 2019, the NISS recorded 31,382 cases of poisoning, predominantly among males (62.85%) and individuals aged 25-44 (44.13%). In all poisoning cases, 82.60% were unintentional. The predominant substances exposure in poisoning cases presenting to outpatient and emergency departments were alcohol (56.38%), medications (14.21%), and pesticides (9.78%). What are the implications for public health practice?: This study has shed light on the evidence for nonfatal poisoning prevention to a variety of different groups, and informed special attention needed for high-risk population and substance exposed.
RESUMO
Introduction: This study seeks to elucidate the evolving trend and identify disparities among subgroups in the mortality rate due to unintentional drowning in individuals under the age of 20 from the timeframe of 2013 to 2021 in China. Methods: Data retrieved from the National Mortality Surveillance System served as a foundation for estimating the unintentional drowning mortality rate. The inadvertent drowning mortality rate for individuals below the age of 20 was computed, differentiated by categorization groups such as age, gender, areas, and regions within each given year. The linear regression model was employed to calculate the annual percent of change (APC) with its 95% confidence interval (CI), providing a depiction of the mortality rate's shifting trend. Results: In 2021, the inadvertent drowning fatality rate for individuals under 20 years of age in China was recorded at 3.28 per 100,000. A steady reduction was observed in the national drowning mortality rate from 6.60 per 100,000 in 2013 down to 3.28 per 100,000 in 2021, signifying a cumulative decrease of 50.30% [APC=-9.06% (95% CI: -11.31%, -6.76%)]. Across all sexes, regions, age groups, and residential areas, a consistent decline in mortality rates was evident between 2013 and 2021. Conclusion: An analysis of the data from 2013 to 2021 reveals a declining trend in the mortality rate due to unintentional drowning among individuals under 20 years of age in China. However, the rate of decline varied when stratified by sex, urban versus rural locations, age-specific groups, and geographical regions.
RESUMO
Background and Objectives: Housing is one of the main places where falls occur; however, few studies have examined housing environmental factors driving fall risk. This study aimed to explore the associations between housing environmental factors and falls in China. Research Design and Methods: The study included data of middle-aged and older adults aged ≥45 years from 4 waves of the China Health and Retirement Longitudinal Study. We assessed 7 housing environmental factors: building materials, toilet types, household tidiness, household cooking fuels, and access to electricity, running water, and bathing facilities. Based on these, we divided housing environments into 3 types: good (0-2 poor factors), moderate (3-5 poor factors), and poor (6-7 poor factors). Falls incidence (yes or no) was self-reported during the survey period. We applied the Cox proportional hazard model to estimate the associations, adjusting for a set of covariates such as sociodemographic characteristics, lifestyles, and disease status. Results: A total of 12,382 participants were analyzed, and the incidence of falls was 31.7%. According to the fully adjusted model, having a squatting toilet (hazard ratio [HR]â =â 1.14, 95% confidence interval [CI]â =â 1.03-1.26), household untidiness (HRâ =â 1.09, 95% CIâ =â 1.01-1.18), and solid fuel use for cooking (HRâ =â 1.10, 95% CIâ =â 1.02-1.18) were associated with a higher risk of falls (psâ <â .05), compared to their counterparts. We found a linear relationship between housing environments and falls (p for trendâ =â .001). Specifically, moderate (HRâ =â 1.16, 95% CIâ =â 1.06-1.27) and poor housing environments (HRâ =â 1.21, 95% CIâ =â 1.08-1.34) were associated with a higher risk of falls compared to a good housing environment. Discussion and Implications: Among middle-aged and older Chinese adults, a better household environment, including sitting toilets, tidy living conditions, and clean fuel use for cooking, may reduce the risk of falls. The evidence from our study suggests the need to implement age-friendly housing environments to prevent falls and disability in an aging society.
RESUMO
The protein kinase ATR is essential for replication stress responses in all eukaryotes. Ribonucleotide reductase (RNR) catalyzes the formation of deoxyribonucleotide (dNTP), the universal building block for DNA replication and repair. However, the relationship between ATR and RNR is not well understood. Here, we show that ATR promotes the protein stability of RNR in Arabidopsis. Through an activation tagging-based genetic screen, we found that overexpression of TSO2, a small subunit of RNR, partially suppresses the hypersensitivity of the atr mutant to replication stress. Biochemically, TSO2 interacts with PRL1, a central subunit of the Cullin4-based E3 ubiquitin ligase CRL4PRL1, which polyubiquitinates TSO2 and promotes its degradation. ATR inhibits CRL4PRL1 to attenuate TSO2 degradation. Our work provides an important insight into the replication stress responses and a post-translational regulatory mechanism for RNR. Given the evolutionary conservation of the proteins involved, the ATR-PRL1-RNR module may act across eukaryotes.

Background: Understanding the occurrence and severity of child injuries is the cornerstone of preventing child injuries. Currently, there is no standardized child injury surveillance dataset in China. Methods: Multistage consultation by a panel of Chinese experts in child injury to determine items to include in the core dataset (CDS) was performed. The experts participated in two rounds of the modified Delphi method comprising a consultation questionnaire investigation (Round 1) and a face-to-face panel discussion (Round 2). Final consensus was established based on the opinions of the experts regarding the modified CDS information collection items. Enthusiasm and authority exhibited by the experts were evaluated by the response rate and using the expert authority coefficient, respectively. Results: The expert panel included 16 experts in Round 1 and 15 experts in Round 2. The experts during both rounds had a high degree of authority, with an average authority coefficient of 0.86. The enthusiasm of the experts was 94.12%, and the proportion of suggestions reached 81.25% in Round 1 of the modified Delphi method. The draft CDS evaluated in Round 1 included 24 items, and expert panelists could submit recommendations to add items. Based on findings in Round 1, four additional items, including nationality, residence, type of family residence, and primary caregiver were added to the draft of the CDS for Round 2. After Round 2, consensus was reached on 32 items arranged into four domains-general demographic information, injury characteristics, clinical diagnosis and treatment, and injury outcome-to include in the final CDS. Conclusion: The development of a child injury surveillance CDS could contribute to standardized data collection, collation, and analysis. The CDS developed here could be used to identify actionable characteristics of child injury to assist health policymakers in designing evidence-based injury prevention interventions.
RESUMO
Exposure to air pollutants is considered to be associated with mental disorders (MD). Few studies have addressed joint effect of multiple air pollutants and meteorological factors on admissions of MD. We examined the association between multiple air pollutants (PM2.5, PM10, O3, SO2, and NO2), meteorological factors (temperature, precipitation, relative humidity, and sunshine time), and MD risk in Yancheng, China. Associations were estimated by a generalized linear regression model (GLM) adjusting for time trend, day of the week, and patients' average age. Empirical weights of environmental exposures were judged by a weighted quantile sum (WQS) model. A machine learning approach, Bayesian kernel machine regression (BKMR), was used to assess the overall effect of mixed exposures. We calculated excess risk (ER) and 95% confidence interval (CI) for each exposure. According to the effect of temperature on MD, we divided the exposure of all factors into different temperature groups. In the high temperature group, GLM found that for every 10 µg/m3 increase in O3, PM2.5 and PM10 exposure, the ERs were 1.926 (95%CI 0.345, 3.531), 1.038 (95%CI 0.024, 2.062), and 0.780 (95% CI 0.052, 1.512) after adjusting for covariates. Temperature, relative humidity, and sunshine time also reported significant results. The WQS identified O3 and temperature (above the threshold) had the highest weights among air pollutants and meteorological factors. BKMR found a significant positive association between mixed exposure and MD risks. In the low temperature group, only O3 and temperature (below the threshold) showed significant results. These findings provide policymakers and practitioners with important scientific evidence for possible interventions. The association between different exposures and MD risk warrants further study.

BACKGROUND: falls and fall-related injuries are common in older adults, have negative effects on functional independence and quality of life and are associated with increased morbidity, mortality and health related costs. Current guidelines are inconsistent, with no up-to-date, globally applicable ones present. OBJECTIVES: to create a set of evidence- and expert consensus-based falls prevention and management recommendations applicable to older adults for use by healthcare and other professionals that consider: (i) a person-centred approach that includes the perspectives of older adults with lived experience, caregivers and other stakeholders; (ii) gaps in previous guidelines; (iii) recent developments in e-health and (iv) implementation across locations with limited access to resources such as low- and middle-income countries. METHODS: a steering committee and a worldwide multidisciplinary group of experts and stakeholders, including older adults, were assembled. Geriatrics and gerontological societies were represented. Using a modified Delphi process, recommendations from 11 topic-specific working groups (WGs), 10 ad-hoc WGs and a WG dealing with the perspectives of older adults were reviewed and refined. The final recommendations were determined by voting. RECOMMENDATIONS: all older adults should be advised on falls prevention and physical activity. Opportunistic case finding for falls risk is recommended for community-dwelling older adults. Those considered at high risk should be offered a comprehensive multifactorial falls risk assessment with a view to co-design and implement personalised multidomain interventions. Other recommendations cover details of assessment and intervention components and combinations, and recommendations for specific settings and populations. CONCLUSIONS: the core set of recommendations provided will require flexible implementation strategies that consider both local context and resources.

Importance: Falls have become a major public health issue in China with population aging. Although falls prevention for older community-dwelling people has been included in the National Essential Public Health Service Package since 2009, there is limited understanding of the implementation of this program. Objective: To identify the associated factors and provide recommendations to inform the better implementation of falls prevention in the Chinese primary health care system. Design, Setting, and Participants: This qualitative study was conducted in 3 purposively selected cities in China from March 1 to June 7, 2021. Health administrators from the local health commission or bureau, staff members from local Centers for Disease Control and Prevention and primary health care facilities and community-dwelling older people were recruited, using a combination of purposive sampling and snowball sampling. Main Outcomes and Measures: In-depth interviews were conducted with health administrators and focus groups with other participants. Data analysis followed the guidance of the Consolidated Framework for Implementation Research. Study outcomes included facilitators and barriers of implementing falls prevention for older people in the Chinese primary health care settings. A framework with recommendations was developed to inform the future intervention implementation. Results: Among a total of 130 participants interviewed, 77 (59.2%) were female and the mean (SD) age was 47.4 (16.7) years. Clear recognition of the challenges and benefits of falls prevention, adaptive regionally tailored guidance plans, and continuous governmental policy and financial support were the major facilitators, whereas the major barriers consisted of insufficient confidence in delivering interventions and poor understanding of the falls burden, low recognition of the importance of falls prevention, limited multisectoral collaboration, and weak financial incentives. A 7-strategy embedded framework-including data-driven surveillance, audit and feedback, implementation strategy, workforce strengthening, community empowerment, internal services integration, and external enabling environment-was developed to foster successful implementation. Conclusions and Relevance: This qualitative study identified major facilitators and barriers to the implementation of falls prevention for older people at the primary care level, which have the potential to contribute to better implementation of falls prevention for older people in the Chinese primary health care system.

BACKGROUND: Falls are major health care concerns for older adults. Pain is associated with increased falls in older adults. However, the impact of pain on functional disability and how this might predispose Chinese older adults to fall is unclear. AIM: The aim of the current study was to examine whether functional disability mediates the association of any pain, back and/or shoulder pain (B-S pain) and leg and/or knees pain (L-K pain) with falls and serious falls. METHODS: The study included 7619 community-dwelling older adults aged 60 years and above from the China Health and Retirement Longitudinal Study. Baseline data were from Wave 3 and fall outcomes were from Wave 4. Functional disability was measured by the ADLs and IADLs scales. We used a logistic regression model to investigate associations between pain and fall outcomes and KHB method to estimate the mediating effects of ADL/IADL disability on pain-fall relationship. RESULTS: After fully adjusting for covariates, the three pain measures (any pain, back and/or shoulder pain, leg and/or knees pain) were significantly associated with fall outcomes. When body pain was compared with no body pain, the proportion mediated by the ADL disability was 28.43% for falls, while the proportion mediated by IADL disability was 17.96% for falls. For associations between specific parts of body pain and falls, the proportions mediated by the ADL disability were 34.18% and 35.89% in back and/or shoulder pain and leg and/or knees pain, respectively, but the proportions reduced to 21.98% and 20.82% when mediated by the IADL disability. However, there were no significant contributions of ADL/IADL disability for the association between specific part of body pain and serious falls. CONCLUSIONS: Pain in general and pain in specific body sites were significantly associated with an increased risk of fall among older adults living in community in China. Functional disability partially mediated the relationship of pain with falls.

Traffic accidents cause considerable economic losses and injuries. Although the adverse effects of a change in ambient temperatures on human health have been widely documented, its effects on road traffic safety are still debated. This systematic review and meta-analysis was performed to synthesize available data on the association between ambient temperature and the risks of road traffic accidents (RTAs) and traffic accident injuries (TAIs). We searched 7 different databases to locate studies. The subgroup analyses were stratified by temperature type, temperature exposure, region, mean temperature, mortality, study period, statistical model, and source of injury data. This study was registered with PROSPERO under the number CRD42021264660. This is the first meta-analysis to investigate the association between ambient temperature and road traffic safety. A total of 34 high-temperature effect estimates were reported, and two additional studies reported the relationship between low temperatures and TAI risk. The meta-analysis results found a significant association between the high temperature and RTAs, and the pooled RR was 1.025 (95%CI 1.014, 1.035). The risk of TAI was also significantly associated with temperature increases. Subgroup analyses found that using daily mean temperatures, the RR value of road traffic accidents was 1.024 (95%CI 0.939, 1.116), and the RR value of road traffic injuries was 1.052 (95%CI 1.024, 1.080). Hourly temperatures significantly increased the risk of RTA, while the risk of TAI was not significantly increased by hourly temperature. The sensitivity analysis indicated that the results were stable, and no obvious publication bias was detected. The results of this systematic review and meta-analysis suggest that increases in ambient temperature are associated with an increased risk of RTAs and TAIs. These findings add to the evidence of the impact of ambient temperature on road traffic safety.

BACKGROUND: Falls in older people have become a major public health concern worldwide, but a comprehensive assessment of the burden of falls for older people in mainland China has not been done. We aimed to investigate the burden of falls among older people at the national and subnational level in mainland China, and explore the trends from 1990 to 2019, using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. METHOD: Using data from GBD 2019, we estimated the burden of falls among people aged 60 years and older by sex and age group in terms of incidence, mortality, and disability-adjusted life-year (DALY) rates and assessed these indicators at the subnational level in 31 geographical units (hereafter called provinces). We investigated the overall trend in the burden of falls across these 31 provinces from 1990 to 2019, and assessed the change in the burden of falls by sex, age group (60-64, 65-69, 70-74, 75-79, and ≥80 years), and province between 1990 and 2019. FINDINGS: In 2019, in mainland China, the incidence rate of falls among people aged 60 years and older was 3799·4 (95% uncertainty interval [UI] 3062·4-4645·0) new falls per 100â000 population, and 39·2 deaths (21·8-48·8) per 100â000 population and 1238·9 DALYs (920·5-1553·2) per 100â000 population were due to falls. We found no significant difference in the burden of falls between males and females. The incidence, mortality, and DALY rates of falls for people aged 80 years and older were significantly higher than those in the other age groups, except for incidence rate, which was non-significantly different between the age 75-79 years group and the oldest age group. Large variations in the incidence and DALY rates of falls were observed across 31 provinces. Although between 1990 and 2019 we found no significant changes in overall mortality due to falls in all provinces and in DALY rates for 23 provinces (DALY rates significantly decreased in two provinces and increased in six provinces), we found large increases in the incidence rate of falls in both males (percentage change between 1990 and 2019: 82·9% [67·4-100]) and females (77·0% [63·3-91·8]). The percentage change in incidence rate of falls between 1990 and 2019 varied from 50·0% (42·2-59·5) for people aged 60-64 years to 123·8% (105·4-141·9) for people aged 80 years and older. All provinces had significant increases in the incidence rate of falls between 1990 and 2019, with Sichuan having the greatest increase (148·5% [125·5-171·4]) and Jilin the smallest increase (14·7% [3·6-26·1]). INTERPRETATION: Between 1990 and 2019, the incidence rate of falls increased substantially in older adults across mainland China, whereas the rates of mortality and DALY of falls among older people remained relatively stable, suggesting improvements in outcomes of falls. Nevertheless, falls remain an ongoing health burden for older people in mainland China, and there is an urgent need to introduce system-wide, integrated, and cost-effective measures to protect and support older people to minimise their risks and combat an increasing absolute burden as the population continues ageing.

SUMMARY: What is already known about this topic? The incidence of falls among older people is 20.7% in China. Falls are the top cause for death from injuries in people aged 65 years and above, and mortality rates increase with age in China. There are few reports on the epidemiological characteristics of falls in older people nationwide in recent years.What is added by this report? This study found that among older people with falls reported in the National Injury Surveillance System (NISS) in 2018, there were more females than males. The peak time for falls was in the morning. Home was the most common site where falls occurred, and leisure activities and housework were the main activities when falls occurred. After falling, the lower limbs and head were most often injured with bruises and fractures. The degree of injury was mainly mild and moderate.What are the implications for public health practice? Data based on the NISS can be used as an additional data source for research on falls in China. This study identified priorities for the control and prevention of falls.
RESUMO
There remains limited literature to facilitate understanding of healthy ageing-related policies in China over the last five-year policy planning cycle. This study aims to characterise all relevant policies and identifies the policy gaps from a health system perspective. A scoping review framework was used. A thorough search for healthy ageing-related policies was performed on the websites of all government ministries affiliated with the Chinese State Council. Essential information was extracted and mapped to an integrated framework of the World Health Organization's Health System Building Blocks and the Chinese 13th Five-Year Plan for Healthy Ageing. A total of 12471 policy documents were identified, while 99 policy documents were included. There were 14 ministries involved in the generation of policies, but multisectoral collaboration between the ministries remained limited. National Health Commission and Ministry of Civil Affairs were the leading ministries. Promoting the integration of medical services and older people care was most frequently addressed within these policies. Applying the health system perspective, governance and financing were often addressed, but there were limited policies on other components of the health system. The findings of this study support four policy recommendations: (1) to enhance multisectoral collaboration in policy development; (2) to strengthen health system building blocks, including healthcare workforce, service delivery, health information, and medical products and technologies; (3) to establish a consolidated policy system centered on the national healthy ageing plan; (4) to formulate a national implementation work plan to promote an integrated health care model for older people.
