We aimed to determine the risk factors associated with abdominal obesity (AO) in suburban adolescents.
This cross-sectional study included adolescents aged 15-17 years from five randomly selected secondary schools in the Hulu Langat district of Selangor state, Malaysia. Waist circumference (WC) was measured at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest. Information on sociodemographic data, dietary habits, physical activity levels and duration of sleep was obtained via interviewer-administered questionnaires. Participants' habitual food intake was determined using a 73-item Food Frequency Questionnaire.
Among 832 participants, 56.0% were girls; 48.4% were Malay, 40.5% Chinese, 10.2% Indian and 0.8% of other ethnic groups. Median age and WC were 16 (interquartile range [IQR] 15-16) years and 67.9 (IQR 63.0-74.6) cm, respectively. Overall prevalence of AO (> 90th percentile on the WC chart) was 11.3%. A higher proportion (22.4%) of Indian adolescents were found to have AO compared with Malay and Chinese adolescents. Logistic regression analysis showed that female gender (adjusted odds ratio [OR] 7.064, 95% confidence interval [CI] 2.087-23.913; p = 0.002), Indian ethnicity (adjusted OR 10.164, 95% CI 2.182-47.346; p = 0.003), irregular meals (adjusted OR 3.193, 95% CI 1.043-9.774; p = 0.042) and increasing body mass index (BMI) (adjusted OR 2.867, 95% CI 2.216-3.710; p < 0.001) were significantly associated with AO.
AO was common among Malaysian adolescents. Female gender, Indian ethnicity, irregular meals and increasing BMI were significant risk factors.
我们旨在确定马来西亚郊区青少年腹部肥胖（AO）的相关危险因素。
这项横断面研究纳入了来自马来西亚雪兰莪州瓜拉冷岳地区五所随机选取的中学的15 - 17岁青少年。在最后一根可触及肋骨下缘与髂嵴顶部之间的中点测量腰围（WC）。通过访谈员管理的问卷获取社会人口学数据、饮食习惯、身体活动水平和睡眠时间等信息。使用包含73个条目的食物频率问卷确定参与者的习惯性食物摄入量。
在832名参与者中，56.0%为女性；48.4%为马来人，40.5%为华人，10.2%为印度人，0.8%为其他种族。年龄中位数和腰围分别为16岁（四分位间距[IQR] 15 - 16）和67.9厘米（IQR 63.0 - 74.6）。AO的总体患病率（WC图表上>第90百分位数）为11.3%。与马来人和华人青少年相比，发现更高比例（22.4%）的印度青少年患有AO。逻辑回归分析显示，女性（调整后的优势比[OR] 7.064，95%置信区间[CI] 2.087 - 23.913；p = 0.002）、印度种族（调整后的OR 10.164，95% CI 2.182 - 47.346；p = 0.003）、饮食不规律（调整后的OR 3.193，95% CI 1.043 - 9.774；p = 0.042）和体重指数（BMI）增加（调整后的OR 2.867，95% CI 2.216 - 3.710；p < 0.001）与AO显著相关。
AO在马来西亚青少年中很常见。女性、印度种族、饮食不规律和BMI增加是显著的危险因素。
