Objective To investigate the prevalence and risk factors of metabolic obesity with normal weight (MON W) in Han nationality adult population,and to identify the cut-off points of body fat percentage (％ BF) by dualenergy X-ray absorptiometry(DXA) for defining MONW.Methods Six hundred and sixty subjects (403 men and 257 women) with body mass index(BMI) ranged from 18.5 to 23.9 kg/m2 were recruited into this study.Waist circumference(WC),blood pressure (BP),BM1,and ％ BF were measured.Serum concentrations of glucose,triglycerides(TG),total cholesterol (TC),high-density lipoprotein-cholesterol (HDL-C),low-density lipoproteincholesterol(LDL-C),serum insulin,and high-sensitivity C-reactive protein (hsCRP) were tested.Those within the highest quartile in the homeostasis model assessment of insulin resistance (HOMA-IR) with a normal BM1 between 18.5 and 23.9 kg/m2 were classified as MONW.Results The prevalence of MONW was 11.34％ for men and 16.34％ for women amongst normal-weight subjects,there was no significant different between men and women in the prevalence(P＞0.05).Multivariable Logistic regression analysis showed that TG(OR =5.92,P=0.001),LDLC (OR =13.65,P =0.009),hsCRP (OR =2.09,P =0.011),WC (OR =2.35,P ＜ 0.01),％ BF (total,OR =3.65,P＜0.01) and ％ BF(abdominal,OR =26.07,P＜0.01) were the risk factors of MONW amongst men.For women,TG (OR =9.12,P＜0.01),LDL-C (OR =2.64,P =0.005),HDL-C (OR =0.020,P＜ 0.01),hsCRP (OR =2.15,P =0.039),WC (OR =1.32,P =0.045),％ BF(total,OR =1.73,P＜0.01) and ％ BF(abdominal,OR =8.43,P＜0.01) were the risk factors of MONW.The cut-off points of ％ BF for diagnosing MONW by ROC were ％ BF≥25％ for men,％ BF ≥35.0％ for women.Conclusion MONW is quite common in Han nationality adult population;.％ BF,WC,hsCRP and lipid profiles were independently associated with MONW ％ BF ≥25 ％ for men,％ BF≥35.0％ for women can be used as reference cut-off.point for diagnosing MONW.

OBJECTIVE: This study was performed to investigate buccal facial depth (BFD) changes after extraction and nonextraction orthodontic treatments in post-adolescent and adult female patients, and to explore possible influencing factors. METHODS: Twelve and nine female patients were enrolled in the extraction and nonextraction groups, respectively. Changes in BFD in the defined buccal region and six transverse and two coronal measuring planes were measured after registering pretreatment and posttreatment three-dimensional facial scans. Changes in posterior dentoalveolar arch widths were also measured. Treatment duration, changes in body mass index (BMI), and cephalometric variables were compared between the groups. RESULTS: BFD in the buccal region decreased by approximately 1.45 mm in the extraction group, but no significant change was observed in the nonextraction group. In the extraction group, the decrease in BFD was identical between the two coronal measuring planes, whereas this differed among the six transverse measuring planes. Posterior dentoalveolar arch widths decreased in the extraction group, whereas these increased at the second premolar level in the nonextraction group. The treatment duration of the extraction group was twice that of the nonextraction group. No differences were found in BMI and Frankfort horizontal-mandibular plane angle changes between the groups. BFD changes in the buccal region moderately correlated with treatment duration and dental arch width change. CONCLUSIONS: BFD decreased in adult female patients undergoing extraction, and this may be influenced by the long treatment duration and constriction of dentoalveolar arch width. However, nonextraction treatment did not significantly alter BFD.
