 In 2021, the Scottish Health Survey was undertaken by telephone which meant that height and weight measurements used to calculate BMI were self-reported by respondents rather than being taken by the interviewer as in previous years. The self-reported measurements for adults were adjusted based on a comparison study by the Health Survey for England.
 Due to disruption to the Scottish Health Survey at the onset of the pandemic, the survey data collected in 2020 was published as experimental statistics and is not comparable with the time series.
