Background: Adolescence is a sensitive period during which sleep undergoes substantial change, increasing vulnerability to sleep disturbances and their health consequences. Psychological inflexibility (PI) and experiential avoidance (EA), operationalized through the Acceptance and Action Questionnaire-II (AAQ-II), have been associated with poorer sleep among adults; however, evidence in adolescents remains scarce. This study examined the association between PI, EA, and sleep-related problems in a representative sample of Spanish adolescents. Methods: A cross-sectional analysis was conducted using data from 623 adolescents (aged 12–17 years; 56.7% girls) from the Eating Healthy and Daily Life Activities (EHDLA) study, conducted in the Valle de Ricote (Murcia, Spain) during 2021–2022. PI and EA were assessed with the Spanish-validated AAQ-II; sleep-related problems were screened using the BEARS (B = Bedtime problems, E = Excessive daytime sleepiness, A = Awakenings during the night, R = Regularity and duration of sleep, S = Snoring) questionnaire across five domains. Generalized linear models were adjusted for sex, age, socioeconomic status, physical activity, sedentary behavior, body mass index (BMI) z-score, energy intake, and sleep duration. Results: Higher AAQ-II scores were significantly associated with increased probabilities of bedtime problems (+0.9% per point; 95% confidence interval [CI]: 0.6–1.1%), excessive daytime sleepiness (+1.0%; 95% CI: 0.7–1.2%), nocturnal awakenings (+0.7%; 95% CI: 0.5–1.0%), and problems with sleep regularity and duration (+0.8%; 95% CI: 0.5–1.1%). Each additional AAQ-II point increased the probability of reporting any sleep-related problem by 1.2% (95% CI: 0.9–1.5%; p < 0.001). Corresponding adjusted odds ratios ranged from 1.04 to 1.06 per point. No significant association was found for snoring. Conclusions: In this cross-sectional study, psychological inflexibility and experiential avoidance were positively associated with several sleep-related problems among adolescents. Longitudinal and intervention studies are warranted before causal or clinical recommendations can be made.

Background/Objectives: University students are at a critical stage for establishing healthy lifestyle habits, yet little is known about their adherence to integrated 24 h movement guidelines that include physical activity, sedentary behavior, and sleep. We examined the proportion of students meeting the Canadian 24 h movement guidelines and associated factors among first-year students at a single Spanish university (UNILIFE-M). Methods: This cross-sectional analysis included 671 first-year students from Universidad Loyola Andalucía (Spain) participating in the UNIversity Students’ LIFEstyle Behaviours and Mental Health (UNILIFE-M) study. Combined guideline adherence used complete cases (n = 646). Behaviors were assessed with the Spanish Physical Activity Scale 2.1 (PAS-2.1S). Adherence required ≥150 min/week of moderate-to-vigorous physical activity, ≤8 h/day of total sedentary time including ≤3 h/day of recreational screen time (both sedentary criteria required), and 7–9 h/night of sleep. Multivariable logistic regression estimated adjusted odds ratios (complete cases on covariates, n = 644). Results: Overall, 137/646 students (21.2%) met all three guidelines, while 54 (8.4%) met none. Male sex was associated with higher odds of adherence (adjusted odds ratio [aOR] = 1.65; 95% confidence interval [95% CI] 1.10 to 2.47), and a lifetime mental health diagnosis was associated with lower odds (aOR = 0.28; 95% CI 0.08 to 0.72). Age > 18 years (aOR = 0.64; 95% CI 0.39 to 1.03) and non-health sciences enrollment (aOR = 0.69; 95% CI 0.46 to 1.03) showed borderline associations that were not robust across sensitivity analyses. Conclusions: In this single-university first-year sample, adherence to the 24 h movement guidelines was relatively low. Associations should be interpreted as cross-sectional correlates, not causal determinants.

Body dissatisfaction is prevalent among adolescents and linked to adverse outcomes. This study examined sociodemographic and anthropometric factors associated with body dissatisfaction in Spanish adolescents. Cross-sectional data from the Eating Healthy and Daily Life Activities (EHDLA) study (N = 1378 students aged 12–17 years) were analyzed. Body dissatisfaction was assessed using the Body Image Dimensional Assessment (BIDA) instrument (overall index and three subscales). Variables included age, sex, socioeconomic status, immigrant status, family structure, parental education, area of residence, and body mass index. Robust multivariable linear models adjusted for all a priori covariates were fitted. Multivariable complete-case models included n = 747 of 1378 adolescents. Younger age, female sex, and excess weight were associated with higher body dissatisfaction on one or more BIDA dimensions. Excess weight showed the largest standardized associations and was linked to all BIDA dimensions (p < 0.001). Maternal educational attainment was not significant in the fully adjusted primary models but remained associated with lower Body Dissatisfaction Score in a reduced-model sensitivity analysis. No significant associations were observed for socioeconomic status, immigrant status, family structure, or area of residence in the primary models. Younger adolescents, female adolescents, and those with excess weight represent subgroups at greater risk of body dissatisfaction. These findings underscore the need for targeted prevention and intervention strategies addressing both anthropometric and sociodemographic risk factors during adolescence.

Background/Objectives: Hallux valgus is a common forefoot deformity whose surgical correction generally yields favorable functional outcomes. However, postoperative complications remain a clinically relevant concern, and the contribution of preoperative risk factors has not been comprehensively characterized in the context of the Spanish population. This study aimed to analyze the relationship between preoperative risk factors and the occurrence of complications after hallux valgus surgery, and to assess whether their accumulation follows a dose–response pattern of increased postoperative risk. Methods: A retrospective observational study was conducted in 123 consecutive patients who underwent hallux valgus surgery between 1 January 2017 and 31 December 2018, with a mean follow-up of 12 months. Variables analyzed included age, sex, deformity severity, active smoking, diabetes mellitus, and antiplatelet or anticoagulant therapy. An accumulated risk factor index based on three clinical risk factors was constructed. Statistical analysis included descriptive statistics, the Cochran–Armitage trend test, and multivariate logistic regression. Results: The mean age was 57.4 years; 82.1% were female. Active smokers accounted for 31.7%, 14.6% had diabetes mellitus, and 13.0% were receiving antithrombotic therapy. The overall complication rate was 20.3%, comprising recurrence (12.2%), chronic residual pain (6.5%), joint stiffness (4.1%), and infection (4.1%). Complication frequency increased progressively from 15.9% in patients without risk factors to 50.0% in those with three concurrent factors (p-trend = 0.038). In multivariate analysis, male sex (odds ratio [OR] 5.39; 95% confidence interval [CI] 1.41–21.19; p = 0.014) and diabetes mellitus (OR 8.37; 95% CI 1.42–63.60; p = 0.026) were independently associated with a higher risk of complications. Conclusions: Hallux valgus surgery generally has a favorable prognosis; however, the presence of preoperative risk factors significantly influences postoperative risk. Diabetes mellitus and the accumulation of risk factors identify patients who could benefit from more rigorous preoperative evaluation, metabolic optimization, and closer postoperative follow-up.
