BACKGROUND/OBJECTIVES: Healthy diet, regular physical activity (PA), and minimizing sedentary behavior (SB) are crucial in promoting adolescents' health and well-being. We assessed adherence to PA and SB recommendations among a representative sample of adolescents and explored their relationship with diet and diet-related behaviors.
Data from the Greek arm of the 2017/2018 international Health Behavior in School-Aged Children (HBSC) cross-sectional study were used, including a probability sample of 3357 students (47.6% boys) who were 11, 13, and 15 years old. PA, SB, consumption of food groups/beverages, and diet-related behaviors were self-reported. Multiple logistic regression was used to identify potential associations.
Most students failed to meet PA (83.9%) (i.e., ≥1 h of moderate-to-vigorous physical activity/day) and SB (90.2%) (i.e., ≤2 h of screen time/day) recommendations. Daily consumption of fruit and vegetables compared to consumption at ≤1 day/week was associated with increased adherence to PA recommendations (adjusted Odds Ratio (aOR) = 2.26, 95% Confidence Intervals (CI): 1.62-3.17 for fruit; aOR = 1.35, 95%CI: 1.00-1.82 for vegetables). Eating sweets ≤1 day/week vs. every day was associated with higher adherence to SB recommendations (aOR = 2.41, 95%CI: 1.43-4.04). Poor diet quality was related to lower adherence to PA and SB recommendations. Daily breakfast consumption vs. never and abstaining from eating at fast-food restaurants were associated with better adherence to PA and SB recommendations. Rarely eating in front of screens was associated with substantially higher odds of adhering to SB recommendations (aOR = 5.79, 95%CI: 3.67-9.14).
Healthier diet/diet-related behaviors were associated with increased PA and reduced SB in this sample of adolescents.
背景/目的：健康饮食、规律的体育活动（PA）以及尽量减少久坐行为（SB）对促进青少年的健康和幸福至关重要。我们评估了青少年代表性样本对PA和SB建议的遵守情况，并探讨了它们与饮食及饮食相关行为的关系。
使用了2017/2018年国际学龄儿童健康行为（HBSC）横断面研究希腊部分的数据，包括3357名11岁、13岁和15岁学生的概率样本（47.6%为男孩）。PA、SB、食物组/饮料的消费以及饮食相关行为均通过自我报告获得。采用多元逻辑回归来确定潜在关联。
大多数学生未达到PA（83.9%）（即每天进行≥1小时中等至剧烈强度的体育活动）和SB（90.2%）（即每天屏幕时间≤2小时）的建议。与每周≤1天食用水果和蔬菜相比，每天食用水果和蔬菜与更高的PA建议遵守率相关（调整后的优势比（aOR）=2.26，95%置信区间（CI）：水果为1.62 - 3.17；蔬菜为aOR = 1.35，95%CI：1.00 - 1.82）。每周≤1天吃甜食与每天吃甜食相比，对SB建议的遵守率更高（aOR = 2.41，95%CI：1.43 - 4.04）。不良的饮食质量与较低的PA和SB建议遵守率相关。每天吃早餐与从不吃早餐相比，以及不在快餐店就餐与更好地遵守PA和SB建议相关。很少在屏幕前吃东西与更高的SB建议遵守几率显著相关（aOR = 5.79，95%CI：3.67 - 9.14）。
在这个青少年样本中，更健康的饮食/饮食相关行为与增加的PA和减少的SB相关。
