To evaluate the impact of a nutritional intervention on nutritional status, ultra-processed food consumption, and quality of life of adolescents with excess weight.
Experimental study with adolescent students with excess weight, divided into two groups, an intervention group and a control group. The nutritional intervention lasted six months, with an educational and motivational approach. Nutritional status (waist circumference and body mass index), quality of life, and ultra-processed food consumption were evaluated before and after the period.
Sixty-two adolescents with overweight or obesity participated in the study, 37 in the intervention group and 25 in the control group, aged 13.2±1.5 years in intervention group, and 13.0±1.8 years in control group, both of which had a higher female participation. There were changes in the body mass index (intervention group Δ: -0.81±2.28, control group Δ: -0.64±1.28) and in the waist circumference for intervention group (Δ:-3.31±5.47). For the pre- and post-ultra-processed food consumption, there was a significant reduction in the consumption of soft drinks in the intervention group (Δ: -0.07 [-0.27 to 0.00]), instant noodles (Δ: -0.03 [-0.07 to 0.00]), and sandwich cookies (Δ: -0.06 [-0.26 to 0.00]). The quality of life increased in the intervention group and decreased in the control group, with no intra- (p=0.162) or intergroup statistical relevance in the pre- (p=0.426) and post- (0.249) intervention period, with a reduction in the emotional domain score, with a significant variation in the intervention group (pre and post; Δ: -19.0±40.6).
There was a decrease in body mass index and waist circumference (central obesity being more often related to insulin resistance), reduction of ultra-processed food consumption (soft drinks, sandwich cookies, and instant noodles), and a tendency toward quality of life improvement (however, there was a decrease in the domains of emotional and school quality of life).
评估营养干预对超重青少年营养状况、超加工食品消费和生活质量的影响。
这是一项针对超重青少年的实验研究，将他们分为干预组和对照组两组。营养干预持续六个月，采用教育和激励方法。在干预前后评估营养状况（腰围和体重指数）、生活质量和超加工食品消费。
共有 62 名超重或肥胖青少年参与了这项研究，其中 37 名在干预组，25 名在对照组，干预组的年龄为 13.2±1.5 岁，对照组为 13.0±1.8 岁，两组女性参与率较高。体重指数（干预组：-0.81±2.28，对照组：-0.64±1.28）和腰围（干预组：-3.31±5.47）均有变化。在超加工食品消费方面，干预组软饮料消费（-0.07 [-0.27 至 0.00]）、方便面（-0.03 [-0.07 至 0.00]）和夹心饼干（-0.06 [-0.26 至 0.00]）有显著下降。干预组生活质量提高，对照组生活质量下降，但干预前后（p=0.162）或组间（p=0.426）均无统计学相关性，干预前后（0.249）情绪域评分降低，干预组变化显著（前后：-19.0±40.6）。
体重指数和腰围（中心性肥胖与胰岛素抵抗关系更密切）下降，超加工食品消费减少（软饮料、夹心饼干和方便面），生活质量有改善趋势（但情绪和学校生活质量领域下降）。
