Annual primary care consultation, test, and prescription costs per person by category of body mass index. The standardised estimates of mean annual costs (in UK 2016 prices) are adjusted for age, region of recruitment, deprivation, educational qualifications, parity, age at birth of first child, smoking, alcohol intake, financial year, and proportion of year with contributed data.
