摘要：Sitting height ratio (SHR) affects the rates of nutritional status based on an adjusted bodymass index (BMIadj) in adults. Height, weight, and sitting height was measured among268 adults (158 men) of the Sarak community in Bundu, Ranchi of Jharkhand, India.BMIadj was computed through age-controlled linear regression of SHR on observed BMI(BMIob) by sex. SHR significantly (p< 0.05) predicted BMIob in either sex. BMIob (men20.3 kg·m-2; women 19.4 kg·m-2) was significantly different (p < 0.05) from BMIadj (men20.5 kg·m-2; women 19.7 kg·m-2). BMIob-based rates of undernutrition (men 28%; women46%) and overweight (men 18%; women 12%) have been estimated. BMIadj marginallyunderestimated the rates of undernutrition (men 27%; women 44%) and overestimatedthe prevalence of overweight (men 20%; women 13%). However, concordance of therates (based on BMIob and BMIadj), appraised with Kappa statistics was significantly (p< 0.05) high (men and women 0.9). Adult Saraks were suffering from high degrees ofundernutrition, and the situation of women was worse. The modeling of BMIadj basedon SHR needs further verification despite high agreement between BMIob and BMIadj inevaluating the rates of nutritional status.
