  • Health complaints among adolescents : Associations with more screen-based behaviours and less physical activity
    Publication . Marques, Adilson; Calmeiro, Luís; Loureiro, Nuno; Frasquilho, Diana; Matos, Margarida Gaspar de
    In this study, we investigated the relationship between screen-based behaviours, physical activity, and health complaints (headaches, feeling low, irritability, and nervousness). Screen-based behaviour included TV viewing, computer use, and time spent playing video games. Data were collected from 4462 Portuguese adolescents (2394 girls) aged 11-16 years. Girls who reported engaging in more screen-based behaviour (hours/day) also reported having more headaches, feeling lower, being more irritable, and feeling more nervous. Boys who reported more screen time were more irritable. Physical activity (times/week) was negatively associated with reports of feeling nervous among girls, and with headaches, feeling low, irritability, and feeling nervous among boys. Considering that time spent using the computer is related with more health complaints, and physical activity was related with fewer health complaints among boys, it is important to develop strategies to reduce adolescents' computer screen time, and to promote physical activity.

    Publication . Marques, Adilson; Peralta, Miguel; Naia, Ana; Loureiro, Nuno; Matos, Margarida Gaspar de
    Background: Monitoring obesity and overweight prevalence is important for assessing interventions aimed at preventing or reducing the burden of obesity. This study aimed to provide current data regarding the prevalence of overweight and obesity of adults, from 20 European countries. Methods: Participants were 34 814 (16 482 men) adults with mean age 50.8 17.7. Data from European Social Survey round 7, 2014, were analysed. Body mass index (BMI) was calculated from self-reported height and weight. Results: The proportion of underweight was only 2%, and 44.9% for normal weight. Overweight and obese accounted for 53.1%. More men than women were overweight (44.7% vs. 30.5%). Older adults were significantly more overweight (42.4%) and obese (20.9%) than middle age and younger adults. Retired people account for a greater proportion of overweight (42.0%) and obese (21.5%), when compared with employed, unemployed and students. People from rural areas were significantly more overweight (39.1 vs. 36.1%) and obese (17.0 vs. 15.3%) than those who lived in urban areas. The estimates indicate that the highest prevalence of overweight was in Czech Republic (45.2%), Hungary (43.7%) and Lithuania (41.7%). For obesity, Slovenia (20.8%), Estonia (19.7%) and the United Kingdom (19.2%) were the countries with the highest prevalence. Conclusion: Even though data was self-reported, and individuals tend to overestimate their height and underestimate their weight, the prevalence of overweight and obesity is considered high. More than half of the European population is overweight and obese. This study strengthens and updates the claims of an excessive weight epidemic in Europe.
