  "description": "This profile supports constraining body weight measurement observations in the context of individuals who are self-measuring blood pressure at home. This profile, in combination with the AMA-IHMI-goal-body-weight-1 profile, addresses the use case of an individual who may be given a weight loss goal as part of a blood pressure treatment plan. The AMA-IHMI-observation-body-weight-1 profile requires the element clothingStatus with the allowed value constrained to undressed. This constraint is to ensure that an individual’s weight is compared to a weight with the same clothing status when outcome of the weight goal is assessed.\r\nThis profile allows the Observation Resource to be extended to include clothing status as an Observation component (i.e., Observation.component clothingStatus).",
