Protocol of a cluster randomised trial of BodyKind: a school-based body image programme for adolescents.

BACKGROUND: Poor body image is prevalent among adolescents and associated with several negative outcomes for their physical and psychological health. There is a pressing need to address this growing public health concern, yet there are few evidence-informed universal programmes for older adolescents that address contemporary body image concerns (i.e., social media). BodyKind is a four lesson, school-based, teacher led, universal body image programme that incorporates empirically supported principles of cognitive dissonance, self-compassion, compassion for others and social activism, to support positive body image development. Building on previous pilot trials in the USA, this paper outlines the protocol for a cluster randomised control trial (cRCT) and implementation evaluation of the BodyKind programme which was culturally adapted for the Irish cultural context. METHODS: We aim to recruit 600 students aged 15-17 years in Transition Year (4th year) across 26 second-level schools in Ireland. Using minimisation, schools will be randomly assigned to receive BodyKind (intervention condition, n=300) or classes as usual (waitlist control, n=300). Teachers in intervention groups will receive training and deliver the programme to students over four weeks, at a rate of one lesson per week. Primary outcomes of body appreciation, body dissatisfaction and psychological wellbeing and secondary outcomes of self-compassion, compassion for others, body ideal internalisation, social justice motives and appearance-based social media use will be assessed at pre-, post- and 2 month follow up. Mediation and moderation analyses will be conducted to identify how and for whom the intervention works best. An implementation evaluation will assess the quality of programme implementation across schools and how this may influence intervention outcomes. Waitlist control schools will receive the programme after the 2-month follow up. CONCLUSION: This study will be the first to implement a cRCT and an implementation evaluation to assess the impact of this multicomponent school-based body image programme designed to support healthy body image development. If shown to be effective, BodyKind will have the potential to improve adolescent body image and wellbeing and inform efforts to implement sustainable and scalable programmes in schools. TRIAL REGISTRATION: The trial was retrospectively registered on 10/10/2023 on ClinicalTrials.gov NCT06076993 .

British Society for Paediatric and Adolescent Dermatology assessment and support of mental health in children and young people with skin conditions: a multidisciplinary expert consensus statement and recommendations.

BACKGROUND: Psychological and mental health difficulties are common in children and young people (CYP) living with skin conditions and can have a profound impact on wellbeing. There is limited guidance on how best to assess and support the mental health of this population, who are at risk of poor health outcomes. OBJECTIVES: To provide consensus-based recommendations on the assessment and monitoring of and support for mental health difficulties in CYP with skin conditions (affecting the skin, hair and nails); to address practical clinical implementation questions relating to consensus guidance; and to provide audit and research recommendations. METHODS: This set of recommendations was developed with reference to the AGREE II instrument. A systematic review and literature appraisal was carried out. A multidisciplinary consensus group was convened, with two virtual panel meetings held: an initial meeting to discuss the scope of the study, to review the current evidence and to identify areas for development; and a second meeting to agree on the content and wording of the recommendations. Recommendations were then circulated to stakeholders, following which amendments were made and agreed by email. RESULTS: The expert panel achieved consensus on 11 recommendations for healthcare workers managing CYP with skin conditions. A new patient-completed history-taking aid ('You and Your Skin') was developed and is being piloted. CONCLUSIONS: The recommendations focus on improved mental health assessments for CYP presenting with a skin condition, with clinical guidance and suggested screening measures included. Information on accessing psychological support for CYP, when required, is given, and recommendations for staff training in mental health and neurodiversity provided. Embedding a psychosocial approach within services treating CYP with skin disease should ensure that CYP with psychological needs are able to be identified, listened to, supported and treated. This is likely to improve health outcomes.

A pedometer-based walking intervention in 45- to 75-year-olds, with and without practice nurse support: the PACE-UP three-arm cluster RCT.

BACKGROUND: Guidelines recommend walking to increase moderate to vigorous physical activity (MVPA) for health benefits. OBJECTIVES: To assess the effectiveness, cost-effectiveness and acceptability of a pedometer-based walking intervention in inactive adults, delivered postally or through dedicated practice nurse physical activity (PA) consultations. DESIGN: Parallel three-arm trial, cluster randomised by household. SETTING: Seven London-based general practices. PARTICIPANTS: A total of 11,015 people without PA contraindications, aged 45-75 years, randomly selected from practices, were invited. A total of 6399 people were non-responders, and 548 people self-reporting achieving PA guidelines were excluded. A total of 1023 people from 922 households were randomised to usual care (n = 338), postal intervention (n = 339) or nurse support (n = 346). The recruitment rate was 10% (1023/10,467). A total of 956 participants (93%) provided outcome data. INTERVENTIONS: Intervention groups received pedometers, 12-week walking programmes advising participants to gradually add '3000 steps in 30 minutes' most days weekly and PA diaries. The nurse group was offered three dedicated PA consultations. MAIN OUTCOME MEASURES: The primary and main secondary outcomes were changes from baseline to 12 months in average daily step counts and time in MVPA (in ≥ 10-minute bouts), respectively, from 7-day accelerometry. Individual resource-use data informed the within-trial economic evaluation and the Markov model for simulating long-term cost-effectiveness. Qualitative evaluations assessed nurse and participant views. A 3-year follow-up was conducted. RESULTS: Baseline average daily step count was 7479 [standard deviation (SD) 2671], average minutes per week in MVPA bouts was 94 minutes (SD 102 minutes) for those randomised. PA increased significantly at 12 months in both intervention groups compared with the control group, with no difference between interventions; additional steps per day were 642 steps [95% confidence interval (CI) 329 to 955 steps] for the postal group and 677 steps (95% CI 365 to 989 steps) for nurse support, and additional MVPA in bouts (minutes per week) was 33 minutes per week (95% CI 17 to 49 minutes per week) for the postal group and 35 minutes per week (95% CI 19 to 51 minutes per week) for nurse support. Intervention groups showed no increase in adverse events. Incremental cost per step was 19p and £3.61 per minute in a ≥ 10-minute MVPA bout for nurse support, whereas the postal group took more steps and cost less than the control group. The postal group had a 50% chance of being cost-effective at a £20,000 per quality-adjusted life-year (QALY) threshold within 1 year and had both lower costs [-£11M (95% CI -£12M to -£10M) per 100,000 population] and more QALYs [759 QALYs gained (95% CI 400 to 1247 QALYs)] than the nurse support and control groups in the long term. Participants and nurses found the interventions acceptable and enjoyable. Three-year follow-up data showed persistent intervention effects (nurse support plus postal vs. control) on steps per day [648 steps (95% CI 272 to 1024 steps)] and MVPA bouts [26 minutes per week (95% CI 8 to 44 minutes per week)]. LIMITATIONS: The 10% recruitment level, with lower levels in Asian and socioeconomically deprived participants, limits the generalisability of the findings. Assessors were unmasked to the group. CONCLUSIONS: A primary care pedometer-based walking intervention in 45- to 75-year-olds increased 12-month step counts by around one-tenth, and time in MVPA bouts by around one-third, with similar effects for the nurse support and postal groups, and persistent 3-year effects. The postal intervention provides cost-effective, long-term quality-of-life benefits. A primary care pedometer intervention delivered by post could help address the public health physical inactivity challenge. FUTURE WORK: Exploring different recruitment strategies to increase uptake.

PACE-UP (Pedometer and consultation evaluation--UP)--a pedometer-based walking intervention with and without practice nurse support in primary care patients aged 45-75 years: study protocol for a randomised controlled trial.

BACKGROUND: Most adults do not achieve the 150 minutes weekly of at least moderate intensity activity recommended for health. Adults' most common physical activity (PA) is walking, light intensity if strolling, moderate if brisker. Pedometers can increase walking; however, most trials have been short-term, have combined pedometer and support effects, and have not reported PA intensity. This trial will investigate whether pedometers, with or without nurse support, can help less active 45-75 year olds to increase their PA over 12 months. DESIGN: Primary care-based 3-arm randomized controlled trial with 12-month follow-up and health economic and qualitative evaluations. PARTICIPANTS: Less active 45-75 year olds (n = 993) will be recruited by post from six South West London general practices, maximum of two per household and households randomised into three groups. Step-count and time spent at different PA intensities will be assessed for 7 days at baseline, 3 and 12 months by accelerometer. Questionnaires and anthropometric assessments will be completed. INTERVENTION: The pedometer-alone group will be posted a pedometer (Yamax Digi-Walker SW-200), handbook and diary detailing a 12-week pedometer-based walking programme, using targets from their baseline assessment. The pedometer-plus-support group will additionally receive three practice nurse PA consultations. The handbook, diary and consultations include behaviour change techniques (e.g., self-monitoring, goal-setting, relapse prevention planning). The control group will receive usual care. OUTCOMES: Changes in average daily step-count (primary outcome), time spent sedentary and in at least moderate intensity PA weekly at 12 months, measured by accelerometry. Other outcomes include change in body mass index, body fat, self-reported PA, quality of life, mood and adverse events. Cost-effectiveness will be assessed by the incremental cost of the intervention to the National Health Service and incremental cost per change in step-count and per quality adjusted life year. Qualitative evaluations will explore reasons for trial non-participation and the interventions' acceptability. DISCUSSION: The PACE-UP trial will determine the effectiveness and cost-effectiveness of a pedometer-based walking intervention delivered by post or practice nurse to less active primary care patients aged 45-75 years old. Approaches to minimise bias and challenges anticipated in delivery will be discussed. TRIAL REGISTRATION: ISRCTN98538934.

Are ethnic and gender specific equations needed to derive fat free mass from bioelectrical impedance in children of South asian, black african-Caribbean and white European origin? Results of the assessment of body composition in children study.

BACKGROUND: Bioelectrical impedance analysis (BIA) is a potentially valuable method for assessing lean mass and body fat levels in children from different ethnic groups. We examined the need for ethnic- and gender-specific equations for estimating fat free mass (FFM) from BIA in children from different ethnic groups and examined their effects on the assessment of ethnic differences in body fat. METHODS: Cross-sectional study of children aged 8-10 years in London Primary schools including 325 South Asians, 250 black African-Caribbeans and 289 white Europeans with measurements of height, weight and arm-leg impedance (Z; Bodystat 1500). Total body water was estimated from deuterium dilution and converted to FFM. Multilevel models were used to derive three types of equation {A: FFM = linear combination(height+weight+Z); B: FFM = linear combination(height(2)/Z); C: FFM = linear combination(height(2)/Z+weight)}. RESULTS: Ethnicity and gender were important predictors of FFM and improved model fit in all equations. The models of best fit were ethnicity and gender specific versions of equation A, followed by equation C; these provided accurate assessments of ethnic differences in FFM and FM. In contrast, the use of generic equations led to underestimation of both the negative South Asian-white European FFM difference and the positive black African-Caribbean-white European FFM difference (by 0.53 kg and by 0.73 kg respectively for equation A). The use of generic equations underestimated the positive South Asian-white European difference in fat mass (FM) and overestimated the positive black African-Caribbean-white European difference in FM (by 4.7% and 10.1% respectively for equation A). Consistent results were observed when the equations were applied to a large external data set. CONCLUSIONS: Ethnic- and gender-specific equations for predicting FFM from BIA provide better estimates of ethnic differences in FFM and FM in children, while generic equations can misrepresent these ethnic differences.

The difference transport makes to child mortality and preventive healthcare efforts: Riders for Health.

The 20th and 21st century witnessed the development of many sophisticated vaccinations and other key preventive health interventions, and yet child mortality in sub-Saharan Africa remains unacceptably high. One of the barriers identified to reducing child mortality in rural regions of Africa is distance and lack of transportation. In order to address this, a growing charitable organisation, Riders for Health (http://www.riders.org) has developed a reliable and cost-effective system for managing vehicles used in all types of healthcare delivery. The system intends to ensure that the delivery of health interventions is never undermined by failing vehicles no matter how harsh the terrain. The system provides reliable transport in direct support of partner healthcare goals and, in so doing, maintains a supply of appropriately managed vehicles, particularly motorcycles. Thereby health workers are empowered, their productivity and coverage enhanced and the efficiency of health interventions they promote maximised.
