Insufficient physical activity and growing obesity levels among Malaysian adolescents are becoming a public health concern. Our study is to identify the trends of self-reported physical activity (PA) levels, blood lipid profiles, and body composition (BC) indices from a cohort of 820 adolescents. The self-reported PA was assessed using a validated Malay version of the PA Questionnaire for Older Children (PAQ-C). Fasting blood samples were collected to investigate their lipid profiles. Height, weight, waist and hip circumferences as well as body fat percentage were measured. The baseline and the first follow-up were conducted in 2012 and 2014, respectively. A downward trend in the PA level was seen in all categories with a significant reduction among all rural adolescents (P = 0.013) and more specifically, PA among girls residing in rural areas dropped significantly (P = 0.006). Either a significant reduction in high-density lipoprotein (HDL) or a significant increment in BC indices (i.e., body mass index [BMI], waist circumference [WC], hip circumference, and body fat percentage [BF %]) were seen in this group. Female adolescents experienced more body fat increment with the reduction of physical activity. If not intervened early, adolescents from rural areas may increase their risk of developing cardiovascular diseases earlier.
马来西亚青少年身体活动不足以及肥胖水平不断上升正成为一个公共卫生问题。我们的研究旨在确定820名青少年队列中自我报告的身体活动（PA）水平、血脂谱和身体成分（BC）指标的趋势。使用经过验证的马来语版大龄儿童身体活动问卷（PAQ-C）评估自我报告的PA。采集空腹血样以调查他们的血脂谱。测量身高、体重、腰围和臀围以及体脂百分比。基线调查和首次随访分别于2012年和2014年进行。所有类别中的PA水平均呈下降趋势，所有农村青少年中PA显著降低（P = 0.013），更具体地说，农村地区女孩的PA显著下降（P = 0.006）。该组中要么高密度脂蛋白（HDL）显著降低，要么BC指标（即体重指数[BMI]、腰围[WC]、臀围和体脂百分比[BF%]）显著增加。女性青少年随着身体活动的减少体脂增加更多。如果不及早干预，农村地区的青少年可能会更早增加患心血管疾病的风险。
