- Movement behaviours, air pollution and health in school-aged children: a cross-sectional study to guide the co-creation of healthier environments – the MOVE-AIR projectPublication . Martins, Clarice; Rufo, João Cavaleiro; Fonseca, Hélder; Padrão, Ana; Baptista, Liliana C.; Santos, Maria Paula; Sousa, Miguel; Zacca, Rodrigo; Silva, José Pedro; Ribeiro, Ana Isabel; Cavaleiro Rufo, JoãoThe MOVE-AIR study was designed to explore the moderating role of movement behaviours on the association between air pollutants and health outcomes in Portuguese children. Secondarily, it aims to characterise the settings (both indoor and outdoor) where children are exposed to air pollutants and to co-create solutions with participants to mitigate the exposure to air pollutants in children’s daily life. This study aims to describe the MOVE-AIR study protocol in detail. Data from 52 primary school children aged 9–11 years will be assessed for indoor and outdoor air pollutants (particulate matter (PM)2.5 and PM10, and carbon dioxide), geo-tracked for distinct settings (ie, home/school, indoor/outdoor) along the day, through an optical monitoring sensor with Global Positioning System incorporated. Health-related biological outcomes, such as interleukin-6, tumour necrosis factor alpha and oxidative parameters, including total antioxidant status and total oxidant status, will be evaluated and the Oxidative Stress Index will be calculated. Children’s cardiopulmonary fitness will be assessed through the shuttle run test, and movement behaviours will be evaluated through accelerometers (wGT3X). Children’s sex, age and parental socioeconomic status will be provided by parents through a questionnaire. The influence of movement behaviours in the link between pollution and health will be analysed through moderating regression models using process for SPSS R software (V.30.0.0). A subsample of class teachers, school leaders, parents and children will be invited to a co-creation process to create solutions to mitigate their daily exposure to air pollutants. The results will contribute to further understanding the moderating role of movement behaviours in the association between air pollution and health, adding a biological layer to the mechanistic links underlying these potential relationships that have not been explored in this target population. Finally, enhancing our comprehension of the living environments and contexts where children are more exposed to air pollution can help to cooperatively create solutions to mitigate their daily exposure to those harmful pollutants.
- The association between cardiovascular disease risk and parental educational level in Portuguese childrenPublication . Duncan, Michael J.; Vale, Susana; Santos, Maria Paula; Ribeiro, José Carlos; Mota, JorgeThe aim of this study was to examine any differences in cardiovascular disease (CVD) risk in Portuguese children split by parental educational level. A cross-sectional school-based study was conducted in 2011 on 359 Portuguese children (202 girls and 157 boys) aged 10 to 17 years (mean age ± SD = 13.9 ± 1.98 years). Height and body mass were assessed to determine body mass index (BMI). Parental education level (PEL) was used as a surrogate for socioeconomic status (SES). Capillary blood sampling was used to determine: Total Cholesterol (TC), Triglycerides (TG), Fasting Glucos (GLUC), High and Low Density Lipoprotein (HDL/LDL). These measurements were combined with measures of systolic blood pressure and cardiorespiratory fitness as z-scores. CVD risk was constructed by summing the z-scores. Analysis of covariance, controlling for BMI, indicated that CVD risk was significantly different across PEL groups (p = 0.01), with CVD risk score being significantly lower in low (p = 0.04) and middle (p = 0.008) PEL groups, compared to high PEL. Moreover, the covariate, BMI was also significant (p = 0.0001, β = 0.023), evidencing a significant positive association between BMI and CVD risk, with higher BMI associated with greater CVD risk. In Portuguese children, significantly greater CVD risk was found for children of high PEL, while higher BMI was associated with greater CVD risk.
