Background & aims When body height cannot be measured, it can be predicted from ulna length (UL). However, commonly used published prediction equations may not provide useful estimates in adults from all ethnicities. This study aimed to evaluate the relationship between UL and height in adults from diverse ethnic groups and to consider whether this...
Article

The dearth of effective childhood obesity prevention is particularly conspicuous for minority groups. To gain trust, engage families, and sustain culturally appropriate interventions, creative settings warrant consideration. We report on the exploratory phase of the mixed-methods DiEt and Active Living (DEAL) study to assess the potential for obesi...
