To determine the association between adherence to the 24-h movement guidelines during adolescence with obesity at adulthood 14 years later in a nationally representative cohort. We analyzed data from 6984 individuals who participated in Waves I (1994–1995) and IV (2008–2009) of the National Longitudinal Study of Adolescent Health (Add Health) in the USA. Obesity was defined by the International Obesity Task Force cut-off points at Wave I and adult cut-points at Wave IV (body mass index [BMI]≥30 kg/m2 and waist circumference [WC]≥102 cm in male and 88 cm in female). Physical activity, screen time and sleep duration were self-reported. Adolescents who met screen time recommendation alone (β = −1.62 cm, 95%CI −2.68 cm to −0.56), jointly with physical activity (β = −2.25 cm, 95%CI −3.75 cm to −0.75 cm), and those who met all three recommendations (β = −1.92 cm, 95%CI −3.81 cm to −0.02 cm) obtained lower WC at Wave IV than those who did not meet any of these recommendations. Our results also show that meeting with screen time recommendations (IRR [incidence rate ratio] = 0.84, 95%CI 0.76 to 0.92) separately and jointly with physical activity recommendations (IRR = 0.86, 95%CI 0.67 to 0.97) during adolescence is associated with lower risk of abdominal obesity at adulthood. In addition, adolescents who met all 24-h movement recommendations had lower risk of abdominal obesity later in life (IRR = 0.76, 95%CI 0.60 to 0.97). Conclusion: Promoting the adherence to the 24-h movement guidelines from adolescence, especially physical activity and screen time, seems to be related with lower risk of abdominal obesity later in life, but not for BMI.

Trajectories of 24-h movement guidelines from middle adolescence to adulthood on depression and suicidal ideation: a 22-year follow-up study
(BMC Public Health, 2022) García Hermoso, Antonio; Ezzatvar, Yasmin; Ramírez Vélez, Robinson; López Gil, José Francisco; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Background: The 24-h movement guidelines for youth and adults recommend the specific duration of physical activity, sedentary time, and sleep duration to ensure optimal health, but little is known about its relationship to mental health indicators. The aim of the study was to explore the association between 24-h movement guidelines in adolescence and its trajectories from middle adolescence (12–17 years old) to adulthood (33–39 years old) with depression and suicidal ideation in adulthood. Methods: This prospective cohort study included individuals who participated in Waves I (1994–1995) and V (2016–2018) of the National Longitudinal Study of Adolescent Health (Add Health) in the United States. Physical activity, screen time and sleep duration were measured using questionnaires. Adults were categorized as having depression if they had a self-reported history of depression and/or prescription medication-use for depression in the previous four weeks. Suicidal ideation was assessed by a self-reported single question in both waves. Poisson regression analyses were used to estimate the incidence rate ratio (IRR) of depression and suicidal ideation at adulthood, according to meeting specific and combinations of 24-h movement guidelines at Wave I and its trajectories from adolescence to adulthood. Results: The study included 7,069 individuals (56.8% women). Adolescents who met physical activity guidelines and all three guidelines at middle adolescence had lower risk of depression (IRR = 0.84, 95%CI 0.72 to 0.98) and suicidal ideation (IRR = 0.74, 95%CI 0.55 to 0.99) at adulthood than those who did not meet any of these guidelines, respectively. Individuals who met the guidelines for screen time and all three guidelines in both adolescence and adulthood had lower risk of depression (screen time, IRR = 0.87, 95% CI 0.72 to 0.98; all three, IRR = 0.37, 95% CI 0.15 to 0.92) and suicidal ideation (screen time, IRR = 0.74, 95% CI 0.51 to 0.97; all three, IRR = 0.12, 95% CI 0.06 to 0.33) than those who never met the guidelines. Additionally, individuals who did not meet all three guidelines in adolescence but met the guidelines in adulthood had lower risk of suicidal ideation than those who never met the guidelines (IRR = 0.81, 95%CI 0.45 to 0.89). Conclusion: Our findings highlight the importance of promoting and maintaining adherence to the 24-h movement guidelines from middle adolescence to adulthood to prevent mental health problems. However, our findings must be interpreted carefully due to declared limitations, e.g., the self-reported assessments which are subject to sources of error and bias or that the dataset used to gauge meeting a guidelines (1994–1996) was made later (2016).

(Springer, 2025-03-06) García Hermoso, Antonio; López Gil, José Francisco; Yáñez-Sepúlveda, Rodrigo; Olivares-Arancibia, Jorge; Páez-Herrera, Jacqueline; Ezzatvar, Yasmin; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Background There is limited research on how adherence to 24 h movement guidelines from adolescence to adulthood afects long-term hypertension outcomes. This study examined the association between sustained adherence to these guidelines and hypertension risk. Methods Analysis was done on data from adolescents 12- to 19-year-olds who took part in Waves I and V of the Add Health Study. Physical activity (PA), screen time, and sleep duration were assessed through self-report questionnaires. Blood pressure (BP) was assessed on the right arm following a 5 min seated rest, utilizing an oscillometric device, and hypertension was defned as systolic/diastolic BP≥140/90 mmHg, physician-diagnosed hypertension, or current antihypertensive medication use. Results This prospective study included a total of 3076 participants (60.3% female), and 802 were diagnosed with hypertension. Meeting sleep duration guidelines at Wave I was associated with reductions in systolic [−0.568 mmHg, 95% biascorrected and accelerated (BCa) confdent interval (CI)−2.128 to−0.011, P=0.044] and diastolic (−0.331 mmHg, 95% BCa CI−1.506 to−0.071, P=0.043) BP at Wave V. Adherence to PA and sleep duration guidelines at both waves further reduced BP, with the greatest decreases observed among participants meeting all three guidelines: systolic (−6.184 mmHg, 95% BCa CI−13.45 to−0.915, P=0.040) and diastolic BP (−3.156 mmHg, 95% BCa CI−6.413 to−0.120, P=0.047). The risk of hypertension was lower among those who met the PA guidelines individually [relative risk (RR) 0.710, 95% CI 0.516–0.976, P=0.035] or adhered to all three recommendations (RR 0.699, 95% CI 0.311–0.899, P=0.030) in both waves. Conclusions Our fndings highlight the cardiovascular benefts of consistently adhering to healthy movement behaviors from adolescence through adulthood.

Are 24-hour movement recommendations associated with obesity-related indicators in the young population? A meta-analysis
(Wiley, 2023) López Gil, José Francisco; Tapia-Serrano, Miguel Ángel; Sevil-Serrano, Javier; Sánchez-Miguel, Pedro Antonio; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Objective: This study aimed to determine the relationship between meeting all three 24-hour movement recommendations (i.e., physical activity, sleep duration, and screen time) and obesity-related indicators among young people. Methods: Four databases were systematically searched (PubMed, Scopus, Web of Science, and Cochrane Library). Results: Meeting the 24-hour movement recommendations was cross-sectionally associated with lower overall obesity-related indicators (r = −0.09, 95% CI: −0.11 to −0.06), but no longitudinal association was found. Regarding each obesity-related indicator separately, meeting all three recommendations was related to lower odds of overweight/obesity (odds ratio = 0.65, 95% CI: 0.56 to 0.76) and obesity alone (odds ratio = 0.28, 95% CI: 0.16 to 0.50). An inverse relationship between meeting 24-hour movement recommendations and BMI, BMI z score, waist circumference, and body fat was also found. Regarding subgroup analysis, the association between 24-hour movement recommendations and overall obesity-related indicators was similar regardless of sex, comparison used (meeting all three vs. not meeting [i.e., those who met zero to two of the movement behaviors] or meeting all three vs. none), and type of measure to assess 24-hour movement recommendations (i.e., self-reported or accelerometer-based measures). Conclusions: Meeting all 24-hour movement recommendations may be a crucial factor in maintaining a healthy weight status in the young population.

Twenty-four-hour movement guidelines during middle adolescence and their association with glucose outcomes and type 2 diabetes mellitus in adulthood
(Elsevier, 2022) García Hermoso, Antonio; López Gil, José Francisco; Ezzatvar, Yasmin; Ramírez Vélez, Robinson; Izquierdo Redín, Mikel; Ciencias de la Salud; Osasun Zientziak
Background: The aim of the present study was to determine the association between adherence to the 24-h movement guidelines during middle adolescence and glucose outcomes (glycated hemoglobin and fasting glucose) and type 2 diabetes mellitus (T2DM) in adulthood, 14 and 22 years later. Methods: We analyzed data from apparently healthy adolescents aged 12-18 years who participated in Waves I and II (1994-1996, n = 14,738), Wave IV (2008-2009, n = 8913), and Wave V (2016-2018, n = 3457) of the National Longitudinal Study of Adolescent to Adult Health (Add Health) in the United States. Physical activity, screen time, and sleep duration were measured using questionnaires, and the 24-h guidelines were defined as: 5 or more times moderate-to-vigorous physical activity per week, ≤2 h per day of screen time, and sleeping 8-10 h per day and or night. Capillary and venous whole blood was collected and analyzed to determine glycated hemoglobin and fasting glucose for Waves IV and V, respectively. Results: Only 2.1% of the adolescents met all the 3 guidelines, and 37.8% met none of them. In both waves IV and V, adolescents who met physical activity and screen time guidelines had lower odds of T2DM in adulthood than those who did not meet any of these guidelines (Wave IV; prevalence ratio (PR) = 0.57, 95%CI: 0.21-0.89; Wave V: PR = 0.43, 95%CI: 0.32-0.74). Only for Wave V did adolescents who met all three guidelines have lower odds of T2DM at follow-up compared with those who did not meet any of these guidelines (PR = 0.47, 95%CI: 0.24-0.91). Also, for each increase in meeting one of the 24-h recommendations, the odds of T2DM decreased by 18% (PR = 0.82, 95%CI: 0.61-0.99) and 15% (PR = 0.85, 95%CI: 0.65-0.98) in adulthood for Waves IV and V, respectively. Conclusion: Promoting all 24-h movement guidelines in adolescence, especially physical activity and screen time, is important for lowering the potential risk of T2DM in adulthood.

A cluster randomized controlled trial of the Archena Infancia Saludable project on 24-h movement behaviors and adherence to the mediterranean diet among schoolchildren: a pilot study protocol
(MDPI, 2023) López Gil, José Francisco; García Hermoso, Antonio; Smith, Lee; Gallego, Alejandra; Victoria-Montesinos, Desirée; Ezzatvar, Yasmin; Hershey, María Soledad; Gutiérrez Espinoza, Héctor; Mesas, Arthur; Jiménez-López, Estela; Sánchez-Miguel, Pedro Antonio; López-Benavente, Alba; Moreno Galarraga, Laura; Chen, Sitong; Brazo-Sayavera, Javier; Fernández-Montero, Alejandro; Alcaraz, Pedro E.; Panisello Royo, Josefa María; Tárraga López, Pedro J.; Kales, Stefanos N.; Ciencias de la Salud; Osasun Zientziak
Objective: The aim of this paper is to describe the protocol of pilot cluster randomized controlled trial (RCT) that will evaluate the effects of a lifestyle-based intervention. The Archena Infancia Saludable project will have several objectives. The primary objective of this project is to determine the 6-month effects of a lifestyle-based intervention on adherence to 24-h movement behaviors and Mediterranean diet (MedDiet) in schoolchildren. The secondary objective of this project is to test the intervention effects of this lifestyle-based intervention on a relevant set of health-related outcomes (i.e., anthropometric measurements, blood pressure, perceived physical fitness, sleep habits, and academic performance). The tertiary objective is to investigate this intervention’s “halo” effect on parents’/guardians’ 24-h movement behaviors and adherence to the MedDiet. Methods: The Archena Infancia Saludable trial will be a cluster RCT submitted to the Clinical Trials Registry. The protocol will be developed according to SPIRIT guidelines for RCTs and CONSORT statement extension for cluster RCTs. A total of 153 eligible parents/guardians with schoolchildren aged 6–13 years will be randomized into an intervention group or a control group. This project focuses on two fundamental pillars: 24-h movement behaviors and MedDiet. It will mainly focus on the relationship between parents/guardians and their children. Behavior change strategies for dietary and 24-h movement behaviors in schoolchildren will be based on healthy lifestyle education for parents/guardians through infographics, video recipes, brief video clips, and videos. Conclusions: Most of the current knowledge on 24-h movement behaviors and adherence to the MedDiet is based on cross-sectional or longitudinal cohort studies, warranting a need to design and conduct RCTs to obtain more robust evidence on the effect of a healthy lifestyle program to increase 24-h movement behaviors and to improve adherence to the MedDiet in schoolchildren.

Is meeting with the 24-h movement recommendations linked with suicidality? Results from a nationwide sample of 44,734 US adolescents
(Elsevier, 2024) López Gil, José Francisco; Firth, Joseph; García Hermoso, Antonio; Ciencias de la Salud; Osasun Zientziak
Background: To our knowledge, only few studies have analyzed the relationship between meeting the 24-h movement guidelines and suicidality in adolescents. The aim of this study was twofold: first, to examine the association between meeting the 24-h movement recommendations and suicidal ideation, suicide planning, and attempted suicide in a representative sample of adolescents from the U.S.; and second, to test whether age group, sex, or race moderate these associations. Method: This is a cross-sectional study including pooled data from the 2011, 2013, 2015, 2017, 2019, and 2021 high school Youth Risk Behavior Surveys (YRBS). A total sample of 44,734 participants (48.5 % females) was included. The recommendations of the 24-h movement guidelines included physical activity, screen time, and sleep duration. Suicidality was examined considering three suicide-related behaviors: suicidal ideation (yes/no), suicide planning (yes/no), and attempted suicide (at least one time or more during the past 12 months). Results: Adolescents who met all three recommendations showed a lower likelihood of suicidal ideation (odds ratio [OR] = 0.49, 95 % confidence interval [CI] 0.37 to 0.64, p < 0.001), suicide planning (OR = 0.51, 95 % CI 0.37 to 0.68, p < 0.001), and attempted suicide (OR = 0.66, 95 % CI 0.44 to 0.96, p = 0.038) than those who did not meet all the recommendations. Overall, when younger adolescents, female adolescents, and adolescents of minority races met the 24-h movement recommendations, they had lower odds of suicide-related outcomes than when they did not. Limitations: This is a cross-sectional study using self-reported data. It is not possible to establish cause-and-effect relationships, and the results could be influenced by some biases. Conclusion: This study suggests that meeting the 24-h movement recommendations could play a relevant role in the prevention of suicidal ideation, planning suicide, and attempted suicide in a nationwide sample from the U.S. adolescents.
