Abstract：
BACKGROUND: Contemporary 24-h movement behavior (24-HMB) guidelines provide recommendations on time spent on physical activity (PA), screen time (ST), and sleep (SL). There is evidence of physiological and psychological health benefits associated with meeting such guidelines. However, the prevalence of meeting 24-HMB guidelines among youth prescribed eyeglasses/contact lenses is less clear. The primary purpose of this cross-sectional analysis was to examine the prevalence of partially or fully meeting 24-HMB guidelines in U.S. youth prescribed eyeglasses/contact lenses, and variations in meeting the guidelines by demographic, health status, and environmental attributes.
METHODS: Data from the 2021 National Survey of Children\'s Health (NSCH) yielded a target subpopulation of 8523 youth aged 6-17 years (54.22 % girls) prescribed eyeglasses/contact lenses. The representative sample of US children and adolescents was used to estimate the prevalence of meeting 24-HMB guidelines, and a multinomial logistic regression analysis was conducted to examine the odds of meeting 24-HMB guidelines by demographic, health status, and environmental variables.
RESULTS: Overall, only 6.57 % met all three 24-HMB guidelines, 23.74 % did not meet any of the three 24-HMB guidelines, and 3.57 %, 10.88 %, and 29.98 % met single guidelines for physical activity, screen time, or sleep duration, respectively, while 25.27 % met any of two 24-HMB guidelines. Female participants were less likely to meet PA + SL guidelines (OR = 0.57, 95 % CI [0.38, 0.56]) but more likely to meet ST + SL guidelines (OR = 1.52, 95 % CI [1.20, 1.91]). Hispanic participants were less likely to meet PA + ST (OR = 0.28, 95 % CI [0.14, 0.52]) guidelines and all three guidelines (OR = 0.41, 95 % CI [0.23, 0.71]) while participants identified as black (OR = 0.33, 95 % CI [0.21, 0.51]) were significantly less likely to meet ST + SL guidelines. With respect to health status, overweight status, repeated/chronic physical pain, and born premature, were detrimentally associated with meeting two or more 24-HMB guidelines. Living in neighborhoods with parks or playgrounds and neighborhood safety were positively linked to meeting the guidelines while living in neighborhoods with sidewalks or walking paths was negatively linked to meeting PA + ST guidelines.
CONCLUSIONS: In U.S. youth prescribed eyeglasses/contact lenses the prevalence of meeting all three 24-HMB guidelines was low, especially the low prevalence observed in female participants, Hispanic and black participants, participants with overweight status, repeated/chronic pain, born premature, living in neighborhoods with sidewalks. Policy makers should take initiative to promote integrated guidelines among this special age group for health benefits.

摘要：
背景：当代24小时运动行为（24-HMB）指南提供了有关体力活动（PA）所花费时间的建议，屏幕时间（ST），睡眠（SL）有证据表明，符合此类指南对生理和心理健康有益。然而,在青少年处方眼镜/隐形眼镜中,符合24-HMB指南的患病率并不清楚.本横断面分析的主要目的是检查美国青少年处方眼镜/隐形眼镜中部分或完全符合24-HMB指南的患病率，以及在满足人口统计准则方面的变化，健康状况,和环境属性。
方法：来自2021年全国儿童健康调查（NSCH）的数据产生了8523名6-17岁青年（54.22％的女孩）处方眼镜/隐形眼镜的目标亚群。使用美国儿童和青少年的代表性样本来估计符合24-HMB指南的患病率，并进行了多项逻辑回归分析，以按人口统计检验满足24-HMB指南的几率，健康状况,和环境变量。
结果：总体而言，只有6.57％符合所有三个24-HMB指南，23.74%的人不符合三项24-HMB指南中的任何一项，和3.57%，10.88%，29.98%的人符合体力活动的单一指导方针，屏幕时间,或睡眠持续时间，分别,而25.27%的人符合两项24-HMB指南中的任何一项。女性参与者不太可能符合PA+SL指南（OR=0.57,95%CI[0.38,0.56]），但更可能符合ST+SL指南（OR=1.52,95%CI[1.20,1.91]）。西班牙裔参与者不太可能符合PA+ST(OR=0.28,95%CI[0.14,0.52])指南和所有三个指南(OR=0.41,95%CI[0.23,0.71])，而被确定为黑人(OR=0.33,95%CI[0.21,0.51])的参与者明显不太可能符合ST+SL指南。关于健康状况，超重状态,反复/慢性身体疼痛，早产，与满足两个或两个以上24-HMB指南有不利关系。生活在有公园或游乐场的社区和社区安全与符合准则有积极的联系，而生活在有人行道或步行道的社区与符合PAST准则有消极的联系。
结论：在美国青少年规定的眼镜/隐形眼镜中，满足所有三个24-HMB指南的患病率很低，尤其是女性参与者的低患病率，西班牙裔和黑人参与者，超重状态的参与者，反复/慢性疼痛，早产，生活在有人行道的社区。政策制定者应主动在这一特殊年龄组中推广综合准则，以提高健康福利。
