Results in the context of what is known
In previous research, screening tools for general nutritional health and nutrition related health factors have been developed. (26-28) For example, Huijgen et. al. (26) have developed a simple tool to assess an inadequate habitual diet in clinical practice, which has been incorporated in the e-coaching program Smarter Pregnancy. (29) Furthermore, micronutrient specific FFQs and checklists have been developed for a number of micronutrients. (30-32) To our knowledge, this study is the first to develop a calcium-specific screening method.
