This research aims to explore the relationships between sleep quality and duration and their influence on the intensity and duration of physical activity among Moroccan high school students.A sample of 400 students (both boys and girls) enrolled in secondary schools during the 2023-2024 academic year in the Fès-Meknès region was randomly recruited. A validated self-administered questionnaire was used to assess levels of sports practice and sedentary behaviors among participants.This study showed a positive correlation between levels of sports practice and sleep duration. Participants with higher levels of sports practice demonstrated a significant positive association with both sleep duration and quality.The results suggest that an increase in sports practice may improve sleep quality. However, it is important to consider other factors to enhance overall sleep quality.

Introduction: Nutrition quality has been consistently linked to academic outcomes. Studies across different cultural contexts suggest that adolescents with balanced diets tend to show better well-being and school adjustment. Objective: This study aimed to examine the associations between adolescents’ regular eating habits and their academic performance in the Beni Mellal-Khénifra region of Morocco. Methodology: A descriptive cross-sectional study was conducted with 439 students aged 14 to 20 years. Eating habits were assessed using the Arab Teens Lifestyle Study (ATLS) questionnaire, and academic performance was measured via overall grade point average. Statistical analyses using SPSS explored correlations between dietary patterns and school achievement. Results: The participants’ average age was 15.02 years (43.7% male, 56.3% female). Descriptive analysis showed that fries, fast foods, and sweet drinks were frequently consumed, while fruits, vegetables, and breakfast at home were less common. Spearman’s correlation revealed a positive association between healthy eating (Factor 2) and academic performance (ρ = 0.166, 95% CI [0.08, 0.25], p < 0.001), indicating a small but meaningful effect. Unhealthy food consumption (Factor 1) was not significantly related to GPA. Regression analysis confirmed that higher healthy eating scores predicted better academic performance (B = 0.472, 95% CI [0.214, 0.729], p < 0.001), while unhealthy eating did not show a significant effect, even after controlling for gender, age, education level, and area of residence. Discussion: These findings align with previous research showing links between diet quality and school performance. The small effect size suggests that healthier eating is associated with modest differences in academic outcomes, highlighting that school performance is influenced by multiple factors, including psychosocial and environmental aspects. Conclusions: The study identified significant associations between eating habits and academic performance among adolescents in the Beni Mellal-Khénifra region. Considering dietary patterns in adolescent development research appears valuable. Further longitudinal or experimental studies are recommended to clarify these relationships.

Background/Objectives: Sleep duration and physical activity are important lifestyle behaviors that may influence adolescents’ academic and Physical Education (PE) performance. However, evidence regarding their associations with Physical Education (PE) performance remains limited, particularly in North African populations. This study aimed to examine the relationships between sleep duration, physical activity, and academic and PE performance among Moroccan adolescents. Methods: A cross-sectional study was conducted among 439 Moroccan adolescents aged 14–20 years. Data were collected using the Arab Teens Lifestyle Study (ATLS) questionnaire. Sleep duration, physical-activity level (metabolic equivalent minutes per week [MET-min/week]), overall academic average, average grade in science subjects, and final PE grade were assessed. Pearson correlation analyses and multivariate analysis of variance (MANOVA) with follow-up univariate analyses were performed, with Games–Howell post hoc comparisons used for PE performance. Results: Sleep duration was positively associated with overall academic average (r = 0.147, p = 0.002) and final PE grade (r = 0.167, p = 0.001), but not with average grade in science subjects (r = 0.080, p = 0.099). Physical activity was positively associated with overall academic average (r = 0.169, p < 0.001) and final PE grade (r = 0.166, p = 0.001), but not with average grade in science subjects (r = −0.009, p = 0.851). Overall academic average was strongly correlated with science average (r = 0.809, p < 0.001) and moderately correlated with final PE grade (r = 0.474, p < 0.001). multivariate analysis of variance (MANOVA)revealed a significant but small overall difference in combined academic and PE performance across the four sleep-duration and physical-activity groups (Pillai’s Trace = 0.034, F(6, 870) = 2.522, p = 0.020, partial η² = 0.017). Follow-up analyses showed no significant group differences in overall academic average (F(3, 435) = 1.460, p = 0.225, partial η² = 0.010), whereas PE performance differed significantly across groups (F(3, 435) = 4.040, p = 0.007, partial η² = 0.027). Conclusions: Sleep duration and physical activity showed weak but significant positive associations with overall academic average and PE performance among Moroccan adolescents, whereas neither was significantly associated with average grades in science subjects. Combined sleep-duration and physical-activity groups differed significantly in PE performance, but not in overall academic average, with small effect sizes. These findings suggest that sleep duration and physical activity are associated with adolescent performance, although the magnitude of these associations is modest and should not be interpreted as causal. Further longitudinal research using objective measures of sleep and physical activity is warranted to clarify these relationships.
