Existing reviews on mental health disparities between deaf and hard‐of‐hearing (DHH) and hearing populations have focused predominantly on children, adolescents, or older adults, leaving a gap for working-age adults. We conducted a systematic review comparing the prevalence, incidence, and severity of any DSM-5-TR or ICD-11 mental disorder between DHH and hearing adults aged 18–60 years. We aimed to quantify disparities and examine disorder-specific patterns to inform future research, policy, and service development.

On 13 December 2025, we searched Ovid Medline, Embase, APA PsycINFO and Web of Science. We included analytical observational studies involving DHH and hearing adults aged 18–60 years, reporting mental disorder prevalence, incidence, or severity. Two researchers independently extracted data, and risk of bias (RoB) was assessed using the modified CLARITY tool. We narratively synthesised findings by aggregating outcomes at the study level using two approaches: summary and majority of the effect directions within a study. Subgroup syntheses examined outcome type, study RoB, age group and mental disorder category.

Sixty studies (n = 8 578 466) met inclusion. In the summary-direction synthesis, 58.3% (35/60) of studies reported higher mental disorder outcomes for DHH adults, 21.7% (13/60) found no difference and 20.0% (12/60) had mixed findings; none indicated lower mental disorder outcomes for DHH. Under the majority-direction approach, 65.0% (39/60) showed higher mental disorder outcomes and 35.0% (21/60) no difference. These patterns were consistent across prevalence (62.8–72.1% higher) and severity (61.1% higher). Studies with higher RoB more often reported higher mental disorder outcomes (66.7–72.2%) than lower-RoB studies (54.8–61.9%), though both mirrored the overall synthesis. Effects were similar across younger (61.9–71.4%) and older adult samples (61.1–66.7% higher). Disorder-specific syntheses identified psychotic disorders, post-traumatic stress disorder and suicidal outcomes as having the strongest disparities (≥72.2% higher), followed by general mental disorders, anxiety and depression. Fewer than five studies examined each of the other disorders, thereby limiting conclusions for these disorders.

Most available evidence indicates that the prevalence and severity of mental disorders are higher among DHH adults aged 18–60 years than among hearing adults, with limited evidence on incidence. No studies reported lower aggregated mental disorder outcomes for DHH adults. Addressing these disparities requires targeted intervention research, supported by population-based, longitudinal and (quasi-)experimental studies including comprehensive reporting of participant characteristics. This will inform more tailored interventions, improve screening and ultimately contribute to better mental health and quality of life for DHH adults.

Limited studies have conducted a comprehensive investigation on the impact of China’s birth policy change on the mental health among women of childbearing age. This study aimed to explore the potential impact of China’s Universal two-child policy on depressive symptoms among women of childbearing age, based on national-representative, longitudinal survey data.

Data we employed in this study were derived from the China Family Panel Study (CFPS) for the waves of 2012, 2014, 2016, 2018 and 2020. We included 7481 currently married females (17079 for pooled sample) aged 20–40 years. Depressive symptoms were assessed using the Kessler 6 Rating Scale (K6) and the Center for Epidemiologic Studies Depression Scale (CES-D). All scores were standardized for analysis. We employ the difference-in-difference model to investigate the association between the implementation of the Universal Two-child Policy (UTP) and women’s depressive symptoms.

Women in the exposed group, after implementing UTP, had a standardized score of depressive symptoms 0.10 higher (95% CI: 0.03–0.16, p = 0.007) than during the pre-intervention period after controlling for multiple covariates. They also faced a higher risk of having moderate or severe depressive symptoms (OR = 1.45, 95% CI: 1.12–1.87, p = 0.004). The stratified analysis revealed that the negative impact of UTP on mental health was pronounced among women with advanced age, low education, medium family income, only male offspring before UTP, and no new birth after UTP.

We observed that the implementation of the UTP was associated with increased depressive symptoms among married women of childbearing age in China, with significant heterogeneity across different sociodemographic groups. Greater attention should be paid to the complex psychological conditions of women of childbearing age when adjusting fertility policies, which is crucial to prevent women from suffering poor mental health and to advance high-quality development in population health.

There is growing public health interest in ultra-processed foods (UPF), but limited research exploring consumers’ perceptions of these foods in the United States. We aimed to characterise consumers’ beliefs about UPF, the association between perceived food processing and perceived food healthfulness and alignment between consumers’ perceptions and objective measures of food processing and healthfulness.

In a cross-sectional survey, participants answered questions regarding their beliefs about UPF. They rated the healthfulness and processing levels of a random selection of ten out of forty possible foods. We used descriptive statistics to examine participant beliefs about UPF. We used linear regression models to test associations between perceived processing and perceived healthfulness and between objective and perceived measures of food healthfulness and processing.

We fielded an online survey in the USA in November 2023.

This study included US adults aged ≥ 18 years (n 4455).

Fifty-four percent of participants correctly identified UPF as ‘Food products submitted to a series of industrial processing’ and 52 % correctly identified UPF as, ‘Food products that contain artificial ingredients’. However, one-third of participants believed UPF were genetically modified products. While foods with higher perceived processing tended to have lower perceived healthfulness and individuals perceived UPF as more processed and less healthful than minimally processed foods, healthfulness perceptions better aligned with Food Compass 2.0, a measure that integrates food processing and nutrient-profile.

Educational and policy efforts (e.g. food labeling) are needed to help consumers distinguish UPF and holistically assess the healthfulness of foods and beverages.

This study aimed to assess the oral health status of individuals with schizophrenia and explore its association with behavioural and pharmacological factors, with particular focus on long-term antipsychotic treatment and cumulative anticholinergic burden.

A total of 153 adults with schizophrenia (18–65 years) from the Mental Health Network of Bizkaia (Spain), all under antipsychotic treatment for ≥12 months, were evaluated and compared with 153 controls from the general population. Data on socio-demographic variables, tobacco use and oral hygiene habits were collected. Oral health was assessed using the Decayed, Missing and Filled Teeth (DMFT) index and the Community Periodontal Index of Treatment Needs (CPITN). Unstimulated salivary flow was measured, and subjective xerostomia symptoms were recorded. Cumulative anticholinergic burden was estimated using the Drug Burden Index, considering both psychotropic and non-psychotropic medications. The association between dental health and clinical, behavioural and pharmacological variables was analysed in patients with schizophrenia.

Patients with schizophrenia exhibited significantly poorer oral health than controls, with higher mean DMFT scores (15.3 vs. 10.9; p < 0.001) and more advanced periodontal disease indicated by CPITN. Salivary hypofunction (<0.45 ml/min) was present in 31% of patients versus 12% of controls. In addition, high to very high anticholinergic burden was present in 71.9% of patients with schizophrenia, compared to only 3.3% of controls. In patients with schizophrenia, multivariate analyses identified the following as significant predictors of worse dental status (DMFT): age; smoking; female sex; illness duration; reduced salivary flow; poor tooth brushing; and anticholinergic burden. For periodontal health (CPITN), however, no variable was identified as a significant predictor of high-risk periodontal status.

Oral health is substantially compromised in individuals with schizophrenia, reflecting a multifactorial interplay of behavioural, systemic and pharmacological factors. Both cumulative anticholinergic burden and reduced salivary flow independently contribute to poorer dental health, while periodontal disease appears to result from more complex influences not fully captured with studied variables. These findings underscore the importance of proactive clinical strategies, including regular dental assessments, targeted oral hygiene interventions, interdisciplinary collaboration between mental health and dental care providers and careful review of psychopharmacological regimens to minimize unnecessary anticholinergic exposure. Such integrated approaches are essential to preserve oral health, enhance quality of life and improve long-term outcomes in this vulnerable population.

In the Netherlands, around 750 children (0–21 year) die annually from potentially palliative conditions. The majority of these children reside at home, receiving care from hospital services and primary care. This study aims to examine general practice utilization for pediatric palliative care patients in the last 2 years of life.

A retrospective cohort study was performed using the routine healthcare database of the Julius General Practitioners’ Network. The main outcome for general practitioner (GP) utilization was the number of GP consultations for children in the last 3 months of life. Participants were included who were children (0–21 years), and deceased in the period 01-01-2013 to 31-12-2022 from an underlying chronic condition. Data were analyzed using descriptive statistics and tested for differences in provided care between children who died in hospital and who died at home.

Forty-eight children from 32 GP practices met inclusion criteria. Median age was 10.0 years (interquartile range [IQR] 1.5–17.1). Common diagnoses were oncological (29%), congenital (29%), and metabolic conditions (23%). Ninety-six percent of children had contact with their GP in the last 3 months (median 7 consultations, IQR 3.0–10.0), i.e. 26 children who died in hospital had median 3.5 GP consultations compared to 20 children who died at home median 9.5 GP consultations (p < 0.001). Thirty-five percent of children were documented as being palliative, with 54% having some form of advance care planning discussions documented.

These results demonstrate that GPs are highly involved in providing pediatric palliative care. The palliative nature of these children and advance care planning discussions are not routinely documented and/or performed by GPs. Further insights into guidance that supports GPs, in collaboration with other healthcare professionals, in providing palliative care for children at home and their families are needed.
