Inclusion criteria

Inclusion criteria: Step 1: Inclusion criteria for weight and height measurements: 1. Aged >=18 years attending a routine dental appointment 2. Consent for height and weight measurements to be taken Step 2: Inclusion criteria for intervention 1. Aged >= 18 years attending a dental appointment 2. BMI >=30 kg/m² [white ethnicities] or >=27.5 kg/m² [Asian/Asian British/Black/African/Caribbean/Black British/Middle Eastern/Mixed or multiple ethnicities with an Asian/Black/Middle Eastern background]* 3. Able to provide informed written consent * BMI thresholds described are based on the NHS thresholds, adjusted for ethnicity, suggestive of living with obesity and greater risk of comorbidities such as type 2 diabetes and heart disease and to be in accordance with other research.

Exclusion criteria

Exclusion criteria: Exclusion criteria for weight and height measurements: 1. Unable to understand English sufficiently to complete the screening 2. Pregnant or intending to fall pregnant within the study time period 3. Mobility requirements or special needs precluding taking of height and weight measurements with stadiometer and scales Step 2: Exclusion criteria for intervention: 1. Unable to understand English sufficiently to complete the trial assessments 2. Pregnant or intending to fall pregnant within the study time period 3. Dental team feels it would be unsuitable for a patient to take part in the study (e.g. eating disorder disclosed by patient or patient already enrolled in a clinical weight loss trial or attending a weight management programme)

Design outcomes

Primary

MeasureTime frame
1. Feasibility and acceptability amongst dental patients (adults) of weight screening and primary care dental team referred weight management interventions measured by: 1.1. Number of participants accepting BMI screening at baseline 1.2. Number of eligible patients who accept a conversation about their weight with their dental team at baseline 1.3. How participants living with obesity feel about discussing their weight through a bespoke questionnaire and qualitative interviews at baseline, 7-day follow-up and 6 week follow up 1.4. Number of participants randomised in 6 months 2. Feasibility and acceptability amongst dental teams of weight screening and referral to weight management interventions for adult patients in dental practices measured by: 2.1. Number of dental practices recruited within the study recruitment period 2.2. Pre-study and post-study bespoke questionnaires and focus groups/interviews will examine how dental teams feel about raising the issue of weight opportunistically and signposting to weight management programmes

Secondary

MeasureTime frame
1. To examine the feasibility of collecting weight data measured by number of participants providing data at 6 week follow up 2. Weight change from baseline to follow-up. Baseline weight: calibrated scales and stadiometer in dental practice. 6-week follow-up: participant to send photo standing on home scales and if not possible, to self-report weight Process outcomes: 1. To examine what actions participants take to manage their weight in response to the conversation with the dental team measured by: 1.1. Number of participants who enrol in a study weight management programme 1.2. Number of participants who take action for weight loss following the intervention across both groups as reported in the bespoke follow-up questionnaire at 6 weeks 2. To explore if the intervention is likely to deter patients from visiting their dental practice measured by number of participants who report a negative impact on their relationship with their dental team and avoidance of future dental care as a result of the intervention. Measured at 7-day telephone follow up and/or bespoke questionnaire at 6 week follow-up
