Increasing reports of life-threatening complications in young children exposed to skin-lightening products present a significant public health concern, yet this issue remains under-researched.

To determine the prevalence, maternal perceptions and predictors of early childhood exposure to skin-lightening products among mothers in Southwestern Nigeria.

A cross-sectional, questionnaire-based study.

Three randomly selected government-owned primary healthcare facilities in Ile-Ife, Nigeria.

Three hundred and sixty-nine mothers aged ≥18 years, each with at least one child under 5, recruited by simple random sampling. Data were collected between May and July 2024 using pretested, interviewer–administer semistructured questionnaires. Mothers with acutely ill children were excluded.

Primary outcome was the use of skin lightening products on children while secondary outcomes included maternal use, perceptions and sociodemographic/familial predictors.

Participants’ ages ranged from 18 to 54 years (mean: 30.92±6.11 years). Overall, 19.5% (n=72) mothers practised early childhood skin lightening, with 80.6% of exposed children

This study highlights a high prevalence of early childhood exposure to lightening products in a semiurban Nigerian community, with maternal use emerging as a key associated factor. Although awareness of potential health risks was common, aesthetic preferences for lighter skin tones appeared to outweigh safety concerns. These findings highlight the need for culturally sensitive interventions and further research to inform strategies that promote safer childhood skin-care practices.

Despite growing concerns regarding the impact of smartphone use on adolescents' lifestyle, there is a notable lack of studies utilising national data to explore how smartphone use influences eating habits in this age group. We aimed to investigate the association between smartphone screen time and fast food intake using representative data from Korean adolescents.

Cross-sectional survey.

This cross-sectional analysis used data from the 2017 Korean Youth Risk Behavior Web-based Survey (KYRBS). We used Poisson regression to directly estimate prevalence ratios (PRs) rather than using logistic regression as odds ratios (ORs) tend to overestimate PRs when the outcome is common. Smartphone screen time was categorised into four groups based on the daily time spent using smartphones:

Data from 39 753 individuals were included.

The primary outcome was the frequency of fast food intake, assessed via a self-reported survey that asked: "In the past 7 days, how often did you eat fast food such as pizza, hamburgers, fried chicken, or drink carbonated beverages?". Participants were categorised into two groups based on their median intake: infrequent (≤2 times/week) and frequent (≥3 times/week).

Among 39 753 adolescents, 19 273 reported frequent fast food intake (10 162 (51.9%) boys, 9111 (45.1%) girls), while 20 480 reported infrequent intake (9409 (48.1%) boys, 11 071 (54.9%) girls). The probabilities that adolescents who used smartphones for 6 hours daily would have frequent fast food intake were 1.29 times (95% CI: 1.28 to 1.30) among boys, and 1.43 times (95% CI: 1.42 to 1.44) higher among girls, compared with adolescents who used smartphones for 2 hours daily.

The association between prolonged smartphone screen time and frequent fast food intake in adolescents suggests the need for targeted interventions addressing digital media use to promote healthier eating behaviors.

Sushko et al1 highlight the increasing prevalence of pre-existing diabetes in pregnancy, which represents a risk to maternal and child health. Diabetes in pregnancy is associated with an increased risk of adverse perinatal and postnatal outcomes for pregnant people and infants. Thus, maintaining optimal glycaemic control during preconception and pregnancy is associated with a lower risk of complications. Many interventions and activities aim to improve glycaemic control in pregnancy, which are...

To estimate the association between socioeconomic background (derived from household main earner occupation when the survey respondent was aged 14 years old) and likelihood of working as a doctor in adulthood in the UK, and estimate how associations varied over time for respondents who turned 18 years old in different decades.

Observational study of 10 years of pooled data from a nationally representative government survey.

The United Kingdom (UK).

358 934 respondents to the UK Office for National Statistics Labour Force Survey between July 2014 and September 2023. Respondents aged 22 years old or below or retired respondents aged 65 years old and above were excluded.

Whether the respondent was currently working as a medical practitioner (doctor).

2772 respondents were currently working as doctors (0.8% of respondents). 13% of doctors were from working-class backgrounds (National Statistics Socio-economic Classification 5–8), compared with 43% of non-doctor respondents, while 69% of doctors came from professional backgrounds (vs 32% of non-doctors) (unadjusted proportions). From multivariable Poisson regression models adjusting for year of survey, the year the respondent turned 18, sex, country of birth and ethnic group, the likelihood of being a doctor varied largely according to socioeconomic background, with those from professional backgrounds 3 times and 6 times more likely to become doctors than those from intermediate backgrounds and working class backgrounds, respectively (average predicted probability: 1.6% vs 0.5% vs 0.3%). Respondents growing up in households where the main earner was a doctor were by far the most likely to themselves report working as a doctor (average predicted probability: 10.1%), 15-fold more likely than all respondents with non-doctor backgrounds (risk ratio=15.0, 95% CIs 13.4 to 16.7), and between 3 times and 100 times more likely when compared with other specific occupation groups. Stratified analyses suggested socioeconomic inequalities were highly stable over time among respondents who turned 18 between the 1960s and the 2000s, and then weak evidence of decreasing diversity from 2010 to 2018.

There are large, persistent and potentially widening inequalities in the socioeconomic background of doctors working in the UK between 2014 and 2023, leading to doctors being highly socioeconomically unrepresentative of the general UK population. New data collections on the socioeconomic background of working doctors are needed to monitor this inequality and understand its effects on patient care. Increased and/or alternative efforts may be needed to address this entrenched inequality and improve social mobility into medicine.

This systematic review aims to update and analyse patient perceptions of physician attire, focusing on its impact on the physician–patient relationship across different medical settings and specialties.

A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria.

PubMed, Embase, Cochrane Library and Google Scholar were searched for relevant studies from 1 January 2015 to 1 June 2025.

This review examined studies focused on physician attire and its impact on patient perceptions.

Studies were assessed based on authors, study setting, study design, objective, study population, physician specialty, measures, findings, main conclusion and risk of bias. Then, thematic analysis was employed to synthesise the findings of the articles.

28 studies met the inclusion criteria. Patient preferences for physician attire varied significantly by clinical context, medical specialty and physician gender. In outpatient and primary care settings, mixed evidence was reported, with some studies suggesting that a combination of casual attire and white coats may foster approachability and communication, while others showed no clear preference. In contrast, in high-acuity settings such as emergency rooms and operating theatres, scrubs were consistently favoured, indicating moderate to strong evidence for the association with professionalism and preparedness. During the COVID-19 pandemic, patients expressed stronger preferences for scrubs and PPE, emphasising infection prevention and hygiene. Gender-specific findings indicated that male physicians were perceived as more professional when wearing formal attire with white coats, while female physicians in similar attire were often misidentified as nurses or assistants. Specialty-based differences were also observed, with preferences for white coats in dermatology, neurosurgery and ophthalmology, while scrubs were preferred in anaesthesiology and gastroenterology.

This study demonstrates that physician attire consistently and significantly impacts patients’ perceptions of professionalism, trust and communication. The collective findings provide robust evidence that these perceptions are highly context-dependent, necessitating adaptable dress codes tailored to clinical environments and patient expectations to enhance trust and patient satisfaction.

To test associations between mental well-being across the life course and exposure to childhood physical and/or verbal abuse.

Secondary analysis of combined data from seven cross-sectional general adult population surveys measuring childhood experience of physical and/or verbal abuse and current mental well-being.

Households across England and Wales.

20 687 residents in England and Wales aged 18 years or over.

Self-reported childhood physical and verbal abuse using questions from an Adverse Childhood Experiences tool. Individual and combined components of adult mental well-being measured using the short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS).

Exposure to either childhood physical abuse or verbal abuse was associated independently with a similar significant increase in likelihood of low adult mental well-being, with exposure to both abuse types compounding increases (adjusted ORs 1.52, 1.64, 2.15 respectively, reference category: neither abuse type). Individual components of mental well-being showed similar associations, with adjusted prevalence of never or rarely having felt close to people in the last 2 weeks rising from 7.7% (neither abuse type) to 9.9% (physical abuse), 13.6% (verbal abuse) and 18.2% (both types of abuse). Within sample trends showed a significant drop in the prevalence of child physical abuse from around 20% in those born from 1950 to 1979 to 10% in those born in 2000 or after. However, verbal abuse rose from 11.9% in those born before 1950 to nearly 20% in those born in 2000 or after.

Exposure to childhood physical or verbal abuse have similar associations with lower mental well-being during adulthood. Interventions to reduce child abuse, including physical chastisement, should consider both physical and verbal abuse and their individual and combined consequences to life course health. The potential role of childhood verbal abuse in escalating levels of poor mental health among younger age groups needs greater consideration.

Post-traumatic stress disorder (PTSD) constitutes a significant anxiety disorder that exerts substantial societal and familial impacts, while concurrently imposing an additional as well as a substantial burden on the healthcare system. Beyond the direct expenses incurred in its treatment, PTSD also gives rise to broader economic costs. The details of these costs in the UK are currently, we believe, unknown.

Our methodology was developed collaboratively with a collaborative advisory group of clinicians, patients, carers and other stakeholders. A comprehensive search strategy was devised to identify articles, including systematic reviews evaluating the economic costs linked to PTSD. We adhered to the National Institute for Health and Care Excellence checklist for economic evaluations. After applying our search strategy, the selected included papers were analysed to identify various cost categories contributing to the economic burden of PTSD.

PubMed, PsycInfo, PTSDpubs, EMBASE and Google Scholar were searched from January 1990 until January 2023; the search was revised and re-run in September 2024.

The articles must have been published originally in English and include a detailed evaluation of costs related to PTSD.

Two independent reviewers used standardised methods to search, screen and code included papers. After applying our search strategy, selected included papers were analysed to identify various cost categories contributing to the economic burden of PTSD. Detailed information on per-contact and per-session costs of healthcare variables was obtained at 2020/2021 prices. Additionally, with the advisory group, we ensured the validity of frequencies and unit cost figures associated with variables linked to PTSD. Further, indirect socio-economic costs arising from PTSD were computed.

By extrapolating from cost components identified, our findings indicate an average annual cost exceeding £14 780 per person. Given current 2020/2021 prevalence rates, this translates to an annual societal burden of £40 billion, a figure that does not encompass the many additional financial burdens stemming from PTSD, such as poor or inconsistent employment. This figure does not include the myriad intangible costs ranging from reduced quality of life to suicidality and countless other issues a person may suffer from as a result of PTSD. Finally, this number does not capture the breadth of impact, as it is difficult to quantify how the families, communities and social systems are adversely affected (both financially and otherwise) by the condition.

The economic and societal burden of PTSD in the UK is far greater than what extant research and common understanding indicate, as there is minimal awareness and information relating to indirect costs or ancillary effects such as discrimination, joblessness, substance use and other comorbidities. Ultimately, we found that there exists, conservatively, an annual excess societal burden of £40 billion, or approximately £14 780 per person. We demonstrated that PTSD is a significantly larger burden on society and individuals than estimated and that we are gravely underquantifying the cost of this increasingly prevalent condition.
