RESUMEN
OBJECTIVE: To evaluate the sensitivity of the modified Brief Form of Bruininks Oseretsky Test in identifying motor differences secondary to malnutrition and poverty. METHODS: This longitudinal cohort study was conducted at Nowshero Feroze, Sindh from 2013 to 2014 and comprised data drawn from children who participated in a randomised controlled trial, that assessed responsive stimulation and nutrition interventions in the first two years of life. Outcome measures included motor development assessed using Brief Form of Bruininks Oseretsky Test, child anthropometry and household economic and demographic information. Data was analysed using SPSS 15 and STATA 12. RESULTS: Of the 1058 children, 570(53%) were boys. Moderate-severe stunting was reported in 171(16.12%) subjects, while moderate-severe underweight was reported in 117(11.1%). Also, 591(56%) subjects belonged to poor families, 343(32%) had illiterate mothers, and 392(37%) were food-insecure. Malnutrition, socio-economic status and maternal literacy were significantly associated with a 6-item motor composite of the Brief Form of Bruininks Oseretsky Test (p<0.05). CONCLUSIONS: The 6-item motor composite of the Brief Form of Bruininks Oseretsky Test was found to be a reliable tool to measure motor performance in Pakistani pre-school children.
