A balanced diet is at the heart of healthy growth and development of children and youth, whereas inappropriate eating habits considerably influence the incidence of disorders connected with nutrition, including overweight and obesity. This paper aims at studying nutritional factors of 18-year-old secondary school youth in the urban environment and their effect on the incidence of overweight and obesity.
The survey was conducted among 1,999 secondary school students chosen at random. The research tool consisted an original survey questionnaire. The measurements of respondents' height and body mass provided data for calculating the body mass index.
The percentage of youth with deficient body mass was estimated at 8.4%. The percentage of normal weight students in the surveyed group was estimated at 77.6%. Overweight and obesity characterized 14.0% of the total number. As many as 21.8% of overweight and obese respondents would eat one or two meals as opposed to 16.8% of normal weight students. Three-fourths of the surveyed students would eat breakfast regardless of their nutritional habits. Lunch is eaten by 52.9% of normal weight 18-year-olds and 46.1% of overweight and obese students. The analysis of mealtimes suggests that overweight and obese students would have their breakfast and dinner at later hours than the rest of the surveyed. More than half of the participating students failed to eat lunch (53.9%), and one in four students within this group resigned from supper. Girls would eat fruit and vegetables more frequently than boys several times a day. The percentage of persons in the surveyed groups who would eat fast foods on a daily basis was similar regardless of their nutritional status. Sweetened carbonated beverages would be drunk more often by overweight and obese boys (81.2%) as compared with boys with proper body mass (75.8%). The same type of beverages would be popular with two-thirds of girls, and this result was similar regardless of their nutritional status. About 44.2% of overweight and obese girls and 20% of girls with proper body mass attempted to lose weight, and 5.7% of boys tried to go on a diet. Eating limitations were declared by 16.5% of overweight and obese boys and ca. 3% of normal weight boys.
Within the surveyed group of youth, it was possible to indicate eating errors primarily consisting in irregular eating, too low a number of meals during the day, particularly skipping breakfast, which took place more frequently among overweight and obese students rather than normal weight ones. The survey points to the insufficient intake of vegetables and fruit as opposed to salty and sweet meals. It is essential to convey the knowledge on the causes of overweight and obesity as well as rules of a healthy diet as factors preventing civilization diseases.
均衡饮食是儿童和青少年健康成长与发育的核心,而不良饮食习惯会显著影响与营养相关疾病的发生率,包括超重和肥胖。本文旨在研究城市环境中18岁中学生的营养因素及其对超重和肥胖发生率的影响。
对随机选取的1999名中学生进行了调查。研究工具为一份原创调查问卷。对受访者身高和体重的测量为计算体重指数提供了数据。
体重不足的青少年比例估计为8.4%。被调查群体中体重正常的学生比例估计为77.6%。超重和肥胖者占总数的14.0%。多达21.8%的超重和肥胖受访者会少吃一两顿饭,而体重正常的学生这一比例为16.8%。四分之三的被调查学生无论饮食习惯如何都会吃早餐。52.9%体重正常的18岁青少年和46.1%超重及肥胖的学生吃午餐。用餐时间分析表明,超重和肥胖的学生吃早餐和晚餐的时间比其他被调查者晚。超过一半的参与学生不吃午餐(53.9%),该群体中有四分之一的学生不吃晚餐。女孩每天吃水果和蔬菜的频率比男孩高几次。无论营养状况如何,被调查群体中每天吃快餐的人的比例相似。超重和肥胖的男孩喝含糖碳酸饮料的频率(81.2%)高于体重正常的男孩(75.8%)。同样类型的饮料在三分之二的女孩中很受欢迎,无论营养状况如何,结果都相似。约44.2%的超重和肥胖女孩以及20%体重正常的女孩试图减肥,5.7%的男孩试图节食。16.5%的超重和肥胖男孩以及约3%体重正常的男孩宣称有饮食限制。
在被调查的青少年群体中,可以指出饮食错误主要包括饮食不规律、一天中用餐次数过少,尤其是不吃早餐,这种情况在超重和肥胖学生中比体重正常的学生更频繁发生。调查指出蔬菜和水果摄入量不足,而咸食和甜食摄入量过多。传达关于超重和肥胖的原因以及健康饮食规则的知识至关重要,这些是预防文明病的因素。
