ABSTRACT

OBJECTIVE: The present study examined the association of BMI, fat mass, physical activity engagement (PA), maximal oxygen consumption (VO2max), screen time and academic performance (AP) with Mediterranean diet (MD) adherence in a sample of high socio-economic status (SES) children. DESIGN: A non-randomised design was used. A multilinear regression model was developed using backward elimination. Analysis included variables pertaining to age, BMI, VO2max, fat percentage, AP, PA engagement and screen time. All participants had a high SES and so this variable was not included as a predictor. Data met the assumptions required for multiple regressions in terms of linearity, homoscedasticity, normality, independence and non-multicollinearity. SETTING: Two state and three mixed funding schools in Granada, Spain. PARTICIPANTS: Data were collected from 244 children aged between 10 and 12 years. RESULTS: Better AP, higher PA engagement and lower screen time were found to be predictive of MD adherence. These variables explained 22·9 % of the variance in data measuring adolescent MD adherence. CONCLUSIONS: The present study suggests that, in addition to SES, PA, AP and screen time are important components to consider when targeting improvements in MD adherence in children. It is, therefore, concluded that interventions targeting improvements in PA, AP and screen time are needed to promote MD adherence in children, regardless of SES.

ABSTRACT

(1) Background: The present study aimed to examine the relationship between physical activity (PA), screen time (ST), maximal oxygen uptake (VO2max), Mediterranean diet (MD) adherence, self-esteem (SE) and academic performance (AP) in primary education students. In order to address this aim, an explanatory model was developed to examine the existing relationships between PA, ST, VO2max, MD adherence, SE and AP. Further, the proposed structural model was examined via multi-group analysis as a function of sex and school type. (2) Methods: A non-experimental, descriptive, comparative and cross-sectional study was designed with a total sample of 269 Spanish students (11.29 ± 0.62). Validated questionnaires were administered to collect data on study variables. (3) Results: Relative to boys, girls reported better academic grades and showed a stronger positive relationship between MD adherence and AP, MD adherence and PA, and VO2max and SE. Likewise, girls showed a stronger negative relationship between ST and VO2max, and ST and MD adherence. At the same time, mixed funding school (MFS) students reported higher PA engagement than state school (SS) students. However, SS students reported better MD adherence, ST and AP than MFS students. Further, a stronger positive relationship was found in SS students between MD adherence or VO2max and SE than in MFS students. Also, within the former group, ST was more negatively related to MD adherence and VO2max. (4) Conclusions: Scientific and educational communities must develop future strategies that consider potential determinants in order to target more desirable outcomes.

ABSTRACT

BACKGROUND: It is known that the promotion and acquisition of healthy attitudes is a key factor depending on the academic training provided by the university studies on which students are enrolled.The aim of the present research is to analyse and compare lifestyle habits and health-related quality of life (HRQoL) as a function of academic training. METHODS: A cross-sectional study with a volunteer convenience sample of 707 undergraduate participants aged (21.98 ± 3.50 years). Students were divided into four different groups according to their area of academic training. Socio-demographic variables, adherence to the Mediterranean diet (MD), physical activity (PA) engagement and HRQoL were recorded. RESULTS: PA and sport science students reported better scores in PA (6342.39 ± 2313.99 metabolic equivalents [METs]; P = 0.000), MD adherence (6.33 ± 2.69; P = 0.000) and HRQoL in physical and mental health (MH; 54.85 ± 9.18; 53.70 ± 13.6; P = 0.000). In contrast, non-health-related sciences (NHRS) students reported the lowest scores on assessed items. Students with a medium/high monthly salary reported better MD adherence (6.16 ± 3.07; P = 0.012). In addition, females reported better scores (6.41 ± 2.65; P = 0.000) than males. Further, males indicated better perceptions of MH (46.52 ± 18.84; P = 0.014). Moreover, university students with a high level of MD adherence were revealed to engage in more PA (5181.17 ± 2813.35 METs; P = 0.000) and have better HRQoL with regards to both physical (54.76 ± 8.84; P = 0.000) and MH (48.11 ± 16.73; P = 0.000). CONCLUSIONS: Outcomes point to differences in MD adherence, PA and HRQoL according to academic training. NHRS students who did not know healthy habits reported lower scores for all studied items. This indicates the need for health interventions at universities.

ABSTRACT

Regular physical activity and good adherence to the Mediterranean diet are important for improving physical and mental health. Confinement due to the COVID-19 pandemic has led to a lack of exercise and poor nutrition. Preadolescent mental health, specifically regarding self-esteem, may have been affected. This is particularly relevant between the ages of 10 and 14. The influence of total confinement due to COVID-19 on physical activity and Mediterranean diet adherence, and its relationship with self-esteem was studied in third-year primary school students and first-year secondary school students in the provinces of Granada and Malaga, Spain. Validated questionnaires were administered to evaluate physical activity (PAQ-C), Mediterranean diet adherence (KIDMED) and self-esteem (Rosenberg Scale). In the same way, the FAS III test was used to evaluate socioeconomic status and an ad-hoc questionnaire was developed to collect sociodemographic data and evaluate screen time. Data were analyzed using IBM SPSS 25.0 statistical software. During the period of total confinement, statistically significant differences were found between examined variables, according to sex, school year, school type, socioeconomic status and whether or not the participant had contracted COVID-19. These data were compared with those collected during a previous time period. Those with a low socioeconomic status and girls were most affected.
