Objective: To compare weight status and body mass index z-scores (BMIz) of refugee children upon arrival to the Southeastern US and after resettlement with age- and sex-matched controls of nonrefugee children.
Methods: We identified refugee children resettled between July 2014 and June 2018 to Forsyth County, NC. Refugees were assigned age- and sex-matched controls (3 controls:1 refugee) who received care at the same health care site, were Medicaid insured, and had height and weight recorded at time of their matched refugee's resettlement plus at least 2 additional visits. BMI and BMIz were calculated. Pearson chi-square test assessed differences in weight status at the time of refugee resettlement and at the last measured time point. Multilevel linear mixed-effects regression models assessed change in BMIz by refugee status, adjusting for sex, race/ethnicity, age, and time since resettlement.
Results: This study examined 139 pediatric refugees and 417 nonrefugee controls; 46% were female. At the time of resettlement, refugees had a higher rate of underweight (3.3% vs 1.9%), higher rate of healthy weight (68.9% vs 48.2%), and lower rate of overweight/obesity (27.8% vs 50%), compared to controls P < .001. At the last available time point, compared to controls, refugees had higher rates of underweight (3.3% vs 3.0%) and healthy weight (69.5% vs 54.2%) and lower rates of overweight/obesity (27.2% vs 42.7%), P = .005. Refugees had a lower predicted BMIz compared with controls (adjusted β: -0.78; 95% confidence interval -0.91, -0.66).
Conclusions: Resettled pediatric refugees were found to have significantly lower predicted BMIz than their age- and sex-matched nonrefugee controls.
