Association of obesity, BMI, and Hispanic ethnicity on ambulatory status in children with spinal dysraphism followed near the California-Mexico border

Purpose. Evaluate the relationship between body mass index (BMI), overweight status (OW), or obesity (OB) and ambulatory status in a predominantly Hispanic population of children with spinal dysraphism (SD). Methods. Retrospective data were extracted from records of 272 children and youth aged 0–24 years with a diagnosis of SD. Body mass index (BMI) and OW/OB rates were calculated for children 0–3 years, 4–11 years, and adolescents older than 11. Results. Ethnicity was predominantly Hispanic (65.4%). No difference in mean BMI or OW/OB rate was found between ambulation groups (p = .20; p = .72). Mean BMI and OW/OB rate increased with increasing age in all groups (p < .001; p = .02). Forty-four percent of patients were OW/OB, which was greater among Hispanics (48.2%) compared with non-Hispanics [(35.2%), p = .03]. Female gender was a risk factor for increased BMI among Hispanics (p = .00). Conclusion. Despite no difference in ambulatory status, increasing BMI and OW/OB are associated with Hispanic ethnicity and increasing age.
