Waist circumference measurement: knowledge, attitudes and barriers in patients and practitioners in a multi-ethnic population

Abstract

BACKGROUND: Currently, body mass index (BMI) is widely used to identify health risk due to overweight or obesity. However, waist circumference is considered by many to be a better indicator of health risk than BMI. The primary health care team are ideally suited to screen for people at high risk of glucose intolerance and increased cardiovascular risk using waist circumference measurement (WCM). OBJECTIVES: To determine the knowledge and attitudes of patients and primary care practitioners concerning WCM, with particular reference to exploring barriers in a multi-ethnic setting. METHODS: A qualitative study using purposive sampling, semi-structured interviews and thematic analysis was conducted. Nine general practices were selected from Leicestershire, UK. The participants were 10 practitioners (four practice nurses, six general practitioners) and 18 patients (six south Asians). RESULTS: Two overarching themes were identified from patient and practitioner interviews: understanding of waist size measurement to assess or monitor risk and attitudes related to perceived barriers and facilitators to waist measurement. A few practitioners felt uncomfortable about carrying out WCM and some perceived that patients might feel embarrassed. Practical barriers raised by professionals included lack of time, extra workload and financial implications. In contrast, patients generally raised few barriers to WCM. Being given an explanation appeared to be what was most important to them. No clear differences emerged when comparing views of patients from different ethnic groups or general practitioners and practice nurses. CONCLUSIONS: This study adds to our understanding of views on WCM in a multi-ethnic setting, highlighting factors for consideration if WCM is to be facilitated in routine practice.
