- Healthy lifestyle in children and adolescents and its association with subjective health complaints: findings from 37 countries and regions from the HBSC StudyPublication . Marques, Adilson; Demetriou, Yolanda; Tesler, Riki; Gouveia, Élvio R.; Peralta, Miguel; Matos, Margarida Gaspar deBackground: It is important to clearly understand the factors associated with subjective health complaints. The study aimed to investigate the relationship between subjective health complaints, several health behaviors, and a composite measure of healthy lifestyle. Methods: Data were from the Health Behaviour in School-aged Children (HBSC) 2014 international database. Participants were 167,021 children and adolescents, aged 10–16 years, from 37 countries and regions. A composite score of healthy lifestyle was created using a combination of daily physical activity, daily consumption of fruit and vegetables, <2 hours spent daily in screen-based behaviors, no drinking, and no smoking. The subjective health complaints assessed were headaches, stomach aches, backache, dizziness, feeling low, irritability, nervousness, and sleep difficulties. Results: Those who engage in physical activity every day, spend less than two hours a day in screen-based behaviors, do not drink alcohol, and do not smoke tobacco presented a higher likelihood of not having subjective health complaints. A healthy lifestyle was significantly related to having less of all the subjective health complaints. Those with a healthy lifestyle were 50% (OR = 0.5, 95% CI: 0.5–0.6, p < 0.001) less likely to have multiple health complaints. Conclusions: Healthy behaviors and healthy lifestyles are related with less subjective health complaints and less multiple health complaints.
- Prevalence of risk for exercise dependence: a systematic reviewPublication . Marques, Adilson; Peralta, Miguel; Sarmento, Hugo; Loureiro, Vânia; Gouveia, Élvio R.; Matos, Margarida Gaspar deBackground Exercise dependence (EXD) can be considered an addictive behaviour because it presents signs typical of other addictive behaviours. Despite possible health problems related to EXD, the prevalence of risk for EXD has never been systematically reviewed. Objective This article aimed to systematically review the prevalence of risk for EXD. Methods Studies were identified from searches in the ERIC, PsycINFO, PubMed, Scopus, SPORTDiscus, and Web of Sci‑ ence electronic databases up to June 2018. Empirical studies were selected if (1) they included the outcomes of the prevalence of EXD; (2) participants were regular exercisers; and (3) they were published in either the English, French, Portuguese, or Spanish languages. A total of 34 articles met the inclusion criteria. Results The prevalence of risk for EXD was estimated to be between 3 and 7% of regular exercisers and the university student population, and between 6 and 9% of the athlete population. Conclusion The results of this review indicated that the prevalence of risk for EXD varies with the characteristics of the exerciser, but an overall prevalence of 3–9% is estimated. Risk for EXD is a cause for concern and, from a public health point of view, is a problem that has to be addressed.
