【 摘 要 】

BackgroundBMI and waist circumference (WC) are used to screen for cardio-metabolic risk; however it is unclear how well these indices perform in populations subject to childhood stunting.ObjectivesTo evaluate BMI and WC as indicators of cardio-metabolic risk and to determine optimal cut-off points among 1325 Guatemalan adults (44 % stunted: ≤150 cm women; ≤162 cm men).MethodsCardio-metabolic risk factors were systolic/diastolic blood pressure ≥130/≥85 mmHg, glucose ≥5·5 mmol/l, TAG ≥1·7 mmol/l, ratio of total cholesterol to HDL-cholesterol ≥5·0, and the presence of two or more and three or more of the preceding risk factors. Receiver operating characteristic (ROC) curve analysis was used.ResultsAreas under the ROC curve were in the range of 0·59–0·77 for BMI and 0·59–0·78 for WC among men and 0·66–0·72 and 0·64–0·72 among women, respectively. Optimal cut-off points for BMI were 24·7–26·1 kg/m2 among men (24·5–26·1 kg/m2 stunted; 24·8–26·3 kg/m2 non-stunted) and 26·5–27·6 kg/m2 among women (26·3–27·8 kg/m2 stunted; 26·6–27·9 kg/m2 non-stunted). Optimal cut-off points for WC were 87·3–91·1 cm among men (85·3–89·4 cm stunted; 88·5–93·3 cm non-stunted) and 91·3–95·3 cm among women (90·9–94·4 cm stunted; 91·8–95·6 cm non-stunted).ConclusionOptimal cut-off points for BMI were slightly higher among women than men with no meaningful differences by stature. Optimal cut-off points for WC were several centimetres lower for stunted compared with non-stunted men, and both were substantially lower than the current recommendations among Western populations. Cut-off points derived from Western populations may not be appropriate for developing countries with a high prevalence of stunting.
