OBJECTIVES
Body mass index (BMI), total body fat (TBF), and physical activity in relation to obesity and overweight prevalence among Omani students were studied.
METHODS
A cross-sectional study of 202 Omani students (101 males and 101 females) from Sultan Qaboos University (SQU) was carried out. Data were collected by interview using a structured questionnaire. Weight, TBF and physical activity score (PAS) were measured using TANITA scales, and height measured using a standardised measuring tape.
RESULTS
SUBJECTS WERE CLASSIFIED BASED ON BMI AS: underweight (2.48%), normal weight (69.31%), overweight (26.73%) and obese (1.49%). According to TBF, 32.67% of students had low body fat scores (BFS), 26.73% high BFS and 22.28% very high BFS. Low BFS was insignificantly less likely with the increase in the mean hours of weekly exercising, (odds ratio [OR] = 0.708; 95% confidence interval [CI] = 0.448, 1.119) and the PAS (OR = 0.728; 95% CI= 0.562, 0.944). Among high and very high BFS students, the mean hours of weekly exercising (6.73±1.20) and physical activity scores (7.51±1.67) were higher than those of healthy students. Nutrition knowledge was higher among healthy students compared to low BFS, and high and very high BFS subjects. Higher nutrition knowledge was associated with a non-significant lower risk of low BFS (OR = 0.986; 95% CI = 0.958, 1.015), high and very high BFS (OR = 0.984; 95% CI = 0.961, 1.008).
CONCLUSION
High and very high BFS were prevalent among subjects with sedentary lifestyles. Nutritional and physical activity interventions should be introduced to combat the problem of overweight students.
目的
研究阿曼学生的体重指数（BMI）、全身脂肪（TBF）以及与肥胖和超重患病率相关的身体活动情况。
方法
对苏丹卡布斯大学（SQU）的202名阿曼学生（101名男性和101名女性）进行了横断面研究。通过使用结构化问卷进行访谈收集数据。使用百利达秤测量体重、TBF和身体活动得分（PAS），使用标准卷尺测量身高。
结果
根据BMI将受试者分类为：体重过轻（2.48%）、正常体重（69.31%）、超重（26.73%）和肥胖（1.49%）。根据TBF，32.67%的学生身体脂肪得分（BFS）较低，26.73%的学生BFS较高，22.28%的学生BFS非常高。随着每周平均锻炼小时数的增加，低BFS的可能性降低不显著（优势比[OR]=0.708；95%置信区间[CI]=0.448，1.119），PAS也是如此（OR=0.728；95%CI=0.562，0.944）。在BFS高和非常高的学生中，每周平均锻炼小时数（6.73±1.20）和身体活动得分（7.51±1.67）高于健康学生。与BFS低、高和非常高的受试者相比，健康学生的营养知识更高。较高的营养知识与低BFS、高和非常高BFS的风险降低不显著相关（OR=0.986；95%CI=0.958，1.015），（OR=0.984；95%CI=0.961，1.008）。
结论
久坐不动生活方式的受试者中BFS高和非常高的情况很普遍。应引入营养和身体活动干预措施来应对超重学生的问题。
