Objectives: This systematic review and meta‐analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors. Methods: We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta‐analysis. Subgroup analyses and meta‐regression were employed to explore potential moderating variables and heterogeneity. Results: The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%–59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%–47.6%). Subgroup analyses and meta‐regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools. Conclusions: This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population. Key points: Informal carers of people with dementia contend with unique circumstances that render them susceptible to both loneliness and social isolation.There is a significant prevalence of loneliness and social isolation in informal carers of individuals with dementia.Several significant moderators influence the prevalence of loneliness and social isolation among informal carers of individuals with dementia.Moderator analysis can guide targeted interventions and support systems for at‐risk informal carers of people with dementia to alleviate loneliness and social isolation.

The ageing population has been rapidly growing over recent years. Theoretically, religion seemingly plays an important role in improving older people's health. This study examines whether believing in religion is related to better health conditions among Chinese older adults through a meta-analysis. Two researchers independently extracted the studies from a comprehensive database and grey literature search and evaluated their scientific quality. From the 3,777 potentially eligible papers, just 76 were selected. The pooled effect size detected no significant difference between Chinese religious and non-religious older adults' overall health and wellbeing. Dividing the outcomes into different categories, religious older adults reported both a higher level of anxiety (Hedge's g = −0.392, 95% confidence interval (CI) = −0.494, −0.290; p = 0.004) and yet a higher level of happiness (Hedge's g = 0.342, 95% CI = 0.074, 0.610; p = 0.018). Having a higher proportion of females in the sample is related to a smaller effect size in overall health outcomes (β = −2.205, 95% CI = −3.800, −0.613; p = 0.007) and social support specifically (β = −4.660, 95% CI = −6.261, −3.058; p < 0.0001). This study is among the first to synthesise the quantitative evidence regarding health differences between older religion believers and non-believers in China. It calls for future studies investigating the pathways underlying the religion–health relationship. [ABSTRACT FROM AUTHOR]

Aim: To critically assess the effects of white noise on the pain level, weight gain and vital signs (heart rate, respiratory rate and oxygen saturation) of preterm infants in neonatal intensive care units (NICUs). Design: A systematic review and meta‐analysis of randomised controlled trials (RCTs). Methods: Ten databases (PubMed, Cochrane Library, Embase, Web of Science, CINAHL, PsycINFO, SinoMed, China National Knowledge Infrastructure, VIP and Wanfang Data) were systematically reviewed from inception to July 2022. Two reviewers evaluated the risk of bias separately using the Cochrane Collaboration criteria and extracted data using a predesigned information form. Results: The meta‐analysis included eight eligible RCTs. According to statistical analysis, white noise significantly affected the pain level, weight gain, heart rate, respiratory rate and oxygen saturation in preterm infants. Regardless of the outcome measurement timing, gestational age and birth weight of preterm infants, subgroup analysis demonstrated that white noise reduced the pain level, heart rate and respiratory rate and promoted weight gain in preterm infants in NICUs. Conclusion: White noise is a practical and potentially useful therapy for premature neonates in NICUs. No Patient or Public Contribution. [ABSTRACT FROM AUTHOR]

Objective: Childhood physical abuse (CPA) can lead to adverse mental health outcomes in adulthood, but its potential impact on Chinese populations is still unclear. This meta-analysis is the first to examine the association between CPA and mental health outcomes in Chinese populations. Study Design: Studies published before December 31, 2014 were identified from Embase, CINAHL, Scopus, PsycINFO, PubMed, and Chinese National Knowledge Infrastructure databases. Studies with data on the association between CPA and mental health outcomes from Chinese subjects were included. Twenty-four studies were initially identified but two were excluded because of poor quality. Two reviewers independently extracted data to generate summary effect sizes using a random-effects meta-analytic model. A priori subgroup and sensitivity analyses were performed to evaluate heterogeneity and bias in these studies. Results: Our meta-analysis of 22 studies found a significant positive association between CPA and overall mental health outcomes among all Chinese subjects (pooled effect size: odds ratio [OR] = 2.16, 95% confidence interval [CI] = [1.87, 2.49]) and among community samples (pooled effect size: OR = 2.06, 95% CI [1.71, 2.48]). Based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, diagnostic criteria, CPA was more strongly associated with Axis II (OR = 2.62, 95% CI [2.13, 3.22]) than Axis I disorders (OR = 1.85, 95% CI [1.58, 2.17]). Conclusions: The detrimental effects of CPA on mental health outcomes in Chinese populations were comparable to, if not more than, the West. Contrary to the Chinese belief that physical punishment is a safe way to discipline children, our findings highlight the potential harm to mental health and the need to change this parenting practice.

Background: China has an unusual pattern of suicides, with overall suicide rates in rural areas higher than urban areas. While suicide rates have decreased dramatically, older people increasingly contribute to the overall burden of suicide. However, it is unclear if elderly people within rural areas experience greater suicide risk than those in urban areas. We aimed to systematically review the incidence of suicide in rural and urban China among the elderly (aged over 60 years), with a view to describing the difference in rates between rural and urban areas and trends over time. Methods: Chinese and English language articles were searched for using four databases: EMBASE (Ovid), MEDLINE (Ovid), PsycINFO (EBSCOhost) and CNKI (in Chinese). Articles describing completed suicide among elderly people in both rural and urban areas in mainland China were included. The adapted Newcastle-Ottawa Scale (NOS) was used to assess risk of bias. One reviewer (ML) assessed eligibility, performed data extraction and assessed risk of bias, with areas of uncertainty discussed with the second reviewer (SVK). Random effects meta-analysis was conducted. Suicide methods in different areas were narratively summarised. Results: Out of a total 3065 hits, 24 articles were included and seven contributed data to meta-analysis. The sample size of included studies ranged from 895 to 323.8 million. The suicide rate in the general population of China has decreased in recent decades over previous urban and rural areas. Suicide rates amongst the elderly in rural areas are higher than those in urban areas (OR = 3.35; 95% CI of 2.48 to 4.51; I2 = 99.6%), but the latter have increased in recent years. Insecticide poisoning and hanging are the most common suicide methods in rural and urban areas respectively. Suicide rates for these two methods increase with age, being especially high in elderly people. Conclusions: The pattern of suicide in China has changed in recent years following urbanisation and aging. Differences in suicide rates amongst the elderly exist between rural and urban areas. Addressing the high suicide rate amongst the elderly in rural China requires a policy response, such as considering measures to restrict access to poisons. [ABSTRACT FROM AUTHOR]
