Trends in clinical referrals to specialist gender services historically comprised more assigned male at birth young people. In the last decade, this has shifted in adolescent samples to more assigned female young people. An updated review of the current patterns of referrals is important to better understand the potential changing needs of clinically referred gender-diverse children and adolescents.

Background: Gender-diverse young people experience a cisnormative world and are subject to unique minority stressors, which have been found to contribute to adverse mental health. This research aims to understand the social and personal context unique to gender-diverse people that young people navigate prior to attending specialised services.
Methods: The baseline measure of a newly developed questionnaire, the GIDS Gender Questionnaire (GIDS-GQ), was sent to all young people (or caregivers for those aged under 12) attending the Gender Identity Development Service (GIDS).
Few studies have assessed the effects of hormonal treatments such as gonadotropin-releasing hormone agonists (GnRHa) and gender-affirming hormones (GAH) on mental health outcomes in clinically referred gender-diverse young people from a younger age. Where this research has been conducted, findings have been mixed. This study investigated a cohort of young people before treatment, 1 year into GnRHa, and 1 year into GAH treatment to understand psychological and behavioral impacts over time.

However, it is unclear whether the influence energy labelling has on consumer behaviour differs based on individuals' demographics or characteristics and may therefore produce inequalities in diet. Data were analysed from 12 randomized control trials (N = 8508) evaluating the effect of food and drink energy labelling (vs.
View Article and Find Full Text PDFObjectives: Some gender-diverse young people (YP) who experience clinically significant gender-related distress choose to pursue endocrine treatment alongside psychotherapeutic support to suppress pubertal development using gonadotropin-releasing hormone analogues (GnRHa), and then to acquire the secondary sex characteristics of their identified gender using gender affirming hormones (GAH). However, little is known about the demographics of transgender adolescents accessing paediatric endocrinology services while under the specialist Gender Identity Development Service (GIDS) in England.
Design: Demographics of referrals from the GIDS to affiliated endocrinology clinics to start GnRHa or GAH between 2017 and 2019 (cohort 1), with further analysis of a subgroup of this cohort referred in 2017-2018 (cohort 2) were assessed.
Introduction: The destination of transgender and gender variant young people referred by the National Health Service (NHS) Gender Identity Development Service (GIDS) to, and discharged from the two English paediatric endocrine liaison clinics is not known.
Methods: 1151 young people referred after full assessment by the GIDS; 827 to University College London Hospital since 2008; 324 to Leeds Children's Hospital since 2013. Discharge categorisation was by agreed criteria.

The present research used linked surveillance systems (British Paediatric Surveillance Unit; and the Child and Adolescent Psychiatry Surveillance System) over a 19 month period (1 November 2011-31 May 2013) to notify of young people (4-15.9 years) presenting to secondary care (paediatrics or child and adolescent mental health services) or specialist gender services with features of gender dysphoria (GD). A questionnaire about socio-demographic, mental health, and GD features was completed.

Objectives: Gender service utilisation according to ethnicity is largely under-researched. The present research looked at demographics and service user-engagement according to ethnicity of young people accessing a gender service for children.
Method: A total of 2063 ( 14.
Aim: This narrative review aimed to analyse the methodologies used by quantitative studies to evaluate their evidence for the association between gender diversity and autism spectrum conditions (ASC) in child and adolescent population samples.
Method: A systematic search was conducted for papers published between 2010 and 2020.
Results: Fifteen papers met the inclusion criteria; all reported associations between their defined versions of gender diversity and ASC.

Background: In adolescents with severe and persistent gender dysphoria (GD), gonadotropin releasing hormone analogues (GnRHa) are used from early/middle puberty with the aim of delaying irreversible and unwanted pubertal body changes. Evidence of outcomes of pubertal suppression in GD is limited.
Methods: We undertook an uncontrolled prospective observational study of GnRHa as monotherapy in 44 12-15 year olds with persistent and severe GD.
Literature has documented inflated rates of features associated with autism spectrum (AS) in clinic referred, gender diverse young people. This study examined scores on the Social Responsiveness Scale, Second Edition (SRS-2) over time in a group of clinic referred, gender diverse adolescents accessing gonadotropin-releasing hormone analogues (GnRHa) to supress puberty. Primary caregivers of 95 adolescents presenting to the Gender Identity Development Service (GIDS) completed the SRS-2 prior to receiving endocrine input (mean age: 13.

A systematic search identified randomized controlled trials testing sustained efficacy of diets, foods, supplements or food ingredients on appetite and/or EI. Trials had to include sufficient exposure duration (≥3 days) with appetite and/or EI measured after both acute and repeated exposures.

Methods: An independent-groups design, utilizing an online questionnaire platform tested 458 UK adults (87 men), aged 18-64 years (mean: 30 years) whose BMI ranged from 16 to 41 kg/m (mean: 24 kg/m).
The umami flavour generated by monosodium glutamate (MSG) has been proposed as the marker for the presence of protein in foods. As protein is the most closely regulated macronutrient in the diet, the present study addressed whether acute protein deprivation, habitual protein intake or a combination of the two influenced liking for the taste of MSG. 24 low-restraint male participants (mean age: 22; BMI: 23) consumed either their habitual breakfast (baseline), a low protein breakfast (breakfast meal with low protein milk and milkshake) or a high protein breakfast (breakfast meal with high protein milk and milkshake) on three different days, and then evaluated the acceptability of umami (MSG), salty (NaCl) or sweet (Acesulphame K) tastes at low or high concentrations in a soup context at lunchtime.

Background: Acute and medium-term intervention studies suggest that non-nutritive sweeteners (NNS) are beneficial for weight loss, however there is limited human data on the long-term effects of consuming NNS on weight loss, maintenance, and appetite. Further research is therefore required to elucidate the prolonged impact of NNS consumption on these outcome measures.
Methods/design: A randomized parallel groups design will be used to assess whether regular NNS beverage intake is equivalent to a water control in promoting weight loss over 12-weeks (weekly weight loss sessions; Phase I), then supporting weight maintenance over 40-weeks (monthly sessions; Phase II) and subsequently independent weight maintenance over 52-weeks (Phase III) in 432 participants.
The effect of coconut oil (CO, containing mainly medium chain triglycerides - MCTs) and sunflower oil (SO, containing mainly long chain triglycerides - LCTs) used as fat source (10% fat ice cream) in different ratios (25% CO and 75% SO - 25CO:75SO, 50% CO and 50% SO - 50CO:50SO, 75% CO and 25% SO - 75CO:25SO) was investigated to assess differences in appetite and ad-libitum (evening and snack) food intake using a single blind design. 36 healthy female participants consumed a fixed portion (150g) of ice cream 45min before an ad-libitum dinner and snacks. Appetite sensations were tracked across the day.

Our main objective was to examine whether heightened awareness of observation of food intake affects consumption of different food items during a lunchtime meal. One hundred and fourteen female participants were randomly assigned to an experimental condition designed to heighten participant awareness of observation or a condition in which awareness of observation was lower, before consuming an ad libitum multi-item lunchtime meal in a single session study.

Recent experimental studies have failed to find an effect of plate size on food intake, although the methods used across studies have varied. The aim of the present study was to examine the effect that bowl size had on snack food consumption in a 'typical' snacking context (snacking while watching television).
View Article and Find Full Text PDFPrevious research suggests that monosodium glutamate (MSG) may have a biphasic effect on appetite, increasing appetite within a meal with its flavour-enhancing effect, but enhancing subsequent satiety due to its proposed role as a predictor of protein content. The present study explored this by assessing the impact of a 450 g soup preload differing in MSG concentration (1 % MSG added (MSG+) or no MSG (MSG-)) and nutrient content (low-energy control or high-energy carbohydrate or high-energy protein) on rated appetite and ad libitum intake of a test meal in thirty-five low-restraint male volunteers using a within-participant design. Protein-rich preloads significantly reduced intake at the test meal and resulted in more accurate energy compensation than did carbohydrate-rich preloads.

Objective: We assessed effects of a combination of monosodium glutamate and inosine 5'-monophosphate (MSG/IMP) provided either alone or in a high-energy, high-carbohydrate and -protein soup on appetite during ingestion and postingestive satiety.
The influence of flavour enhancers such as monosodium glutamate (MSG) on satiation and satiety is unclear, and the present study aimed to explore this by examining the effects consumption of soups varying in MSG (1% MSG added or no MSG) and macronutrient content (added carbohydrate, protein or control) had on appetite. 24 non-obese, low-restraint male participants consumed a fixed portion of soup and rated their appetite before, immediately after intake and at 15 minute intervals for 120 min post-ingestion across six sessions. Added MSG significantly increased flavour pleasantness and tended to result in a smaller decrease in hunger immediately after soup ingestion.
