Our objective was to draw growth curves and assess obesity prevalence in adolescents of public schools, and to explore selected food consumption frequency and physical activity.
A cross-sectional study was conducted in Lebanese public schools. From the list of schools provided by the Ministry of Education, a random sample of 20 schools was chosen, distributed in all Lebanese regions. Participants were 2547 adolescents, aged between 11 to 18 years. Anthropometric measures of height and weight were taken, growth curves were drawn. Obesity and at risk of obesity prevalences were also calculated. Selected food intake frequency, physical activity and sedentary behavior were also analyzed.
Growth curves were drawn for boys and girls. Overall, 6.6% of adolescents were obese, while 20.5% were at risk of obesity. There were significant differences in obesity prevalence estimates between age groups in girls : increased age was associated with higher obesity (3.8% in those < or =13 years of age versus 10.6%in those > 17 y ; p = 0.02) ; this trend was not found in boys (6.5% in those < or = 13 y and 7.2% in those > 17 y; p = 0.78). As expected, a significant increase in the risk of being overweight was found with increased frequency of eating fried potatoes, chocolate and eating out. In contrast, eating fruits and having physical activity were associated with a lower risk of being overweight.
In Lebanese public schools, we found high rates of obesity and associated behaviors. Preventing obesity should focus on promoting healthy lifestyles for adolescents of low socioeconomic status.
我们的目的是绘制公立学校青少年的生长曲线并评估肥胖患病率，同时探究特定食物的消费频率和身体活动情况。
在黎巴嫩公立学校开展了一项横断面研究。从教育部提供的学校名单中，随机选取了20所学校，分布在黎巴嫩所有地区。参与者为2547名年龄在11至18岁之间的青少年。测量了身高和体重等人体测量指标，绘制了生长曲线。还计算了肥胖和肥胖风险患病率。对特定食物的摄入频率、身体活动和久坐行为也进行了分析。
绘制了男孩和女孩的生长曲线。总体而言，6.6%的青少年肥胖，而20.5%有肥胖风险。女孩各年龄组的肥胖患病率估计存在显著差异：年龄增长与肥胖率升高相关（13岁及以下者为3.8%，17岁以上者为10.6%；p = 0.02）；男孩中未发现这种趋势（13岁及以下者为6.5%，17岁以上者为7.2%；p = 0.78）。正如预期的那样，发现吃炸土豆、巧克力和外出就餐频率增加会使超重风险显著增加。相比之下，吃水果和进行身体活动与较低的超重风险相关。
在黎巴嫩公立学校，我们发现肥胖率及相关行为发生率较高。预防肥胖应侧重于为社会经济地位较低的青少年推广健康的生活方式。
