ABSTRACT
Knee height can be a proxy for height when standing height cannot be reliably measured. We compared two commonly used equations (Chumlea and Rumapea) that estimate standing height from knee height. We prospectively enrolled 210 children without scoliosis or kyphosis aged 7-12 years (mean age: 10.2 years, 47.6% males) and measured their knee heights and standing heights. A two-tailed T-test was used to compare predicted heights from each of the equations to actual standing height. Chumlea equation was found to be unreliable (p = 0.0376) while Rumapea equation was found to be reliable in estimating standing height (p = 0.878). Additionally, Rumapea equation was also found to be more accurate than Chumlea equation when results were segregated based on gender and race. In conclusion, the Rumapea equation yields more accurate estimates of standing heights than the Chumlea equation in US children aged 7-12 years.
ABSTRACT
Pediatric feeding disorders (PFDs) lack a universally accepted definition. Feeding disorders require comprehensive assessment and treatment of 4 closely related, complementary domains (medical, psychosocial, and feeding skill-based systems and associated nutritional complications). Previous diagnostic paradigms have, however, typically defined feeding disorders using the lens of a single professional discipline and fail to characterize associated functional limitations that are critical to plan appropriate interventions and improve quality of life. Using the framework of the World Health Organization International Classification of Functioning, Disability, and Health, a unifying diagnostic term is proposed: "Pediatric Feeding Disorder" (PFD), defined as impaired oral intake that is not age-appropriate, and is associated with medical, nutritional, feeding skill, and/or psychosocial dysfunction. By incorporating associated functional limitations, the proposed diagnostic criteria for PFD should enable practitioners and researchers to better characterize the needs of heterogeneous patient populations, facilitate inclusion of all relevant disciplines in treatment planning, and promote the use of common, precise, terminology necessary to advance clinical practice, research, and health-care policy.
