The aging process reflects, in many cases, not only a decline in physical activity (PA) and physical fitness (PF), but also an increase in overall levels of sedentary time (ST). In order to hierarchically identify the most powerful correlates related to low and high levels of objectively assessed PA, ST, and PF during the late adulthood, a total of 2666 older adults were cross-sectionally evaluated. Multidimensional correlates were obtained through interview. Using chi-squared automatic detection analysis to identify the cluster of correlates with most impact on PA (<21.4 min/day), ST (≥8 h/day), and PF (<33.3th percentile), was found that the most likely subgroup to be physically inactive consisted of widowers not owning a computer and sport facilities in the neighbourhood (94.7%), while not being widowed, reporting to have a family that exercises and a computer at home (54.3%) represented the subgroup less likely to be inactive. Widowers without sidewalks in the neighbourhood were the most sedentary group (91.0%), while being a married woman and reporting to have space to exercise at home (40%) formed the most favourable group of correlates regarding ST. Men reporting a financial income <500€ and physical problems frequently formed the group with the lowest PF level (70.3%). In contrast, the less likely subgroup to have low levels of PF level consisted of having a financial income ≥1000€ and a computer at home (3.4%). Future interventions should target widowers with limited accessibility to computer and urban/sport-related infrastructures, as well as impaired older adults with low financial income. Highlights Chi-squared automatic interaction detection was used to identify and hierarchise correlates of objectively measured physical activity, sedentary time, and fitness. Widowers not having a computer at home and sport facilities in the neighbourhood were the most likely to be physically inactive, while not being widowed, having a family that exercises and a computer at home represented the subgroup less likely to be physically inactive. The most likely to be classified as sedentary were widowers without sidewalks in the neighbourhood, while the most favourable group of correlates regarding ST was formed by married women and reporting to have space to exercise at home. Individuals with a low financial income and physical problems comprised the population subgroup with the lowest PF levels, while having a medium-high financial income and a computer at home represented the less likely subgroup to have low levels of PF.

Objective: This study aimed to identify health behaviours that determine adolescent's adherence to the Mediterranean diet (MD) through a decision tree statistical approach. Design: Cross-sectional study, with data collected through a self-fulfilment questionnaire with five sections: (1) eating habits; (2) adherence to the MD (KIDMED index); (3) physical activity; (4) health habits and (5) socio-demographic characteristics. Anthropometric and blood pressure data were collected by a trained research team. The Automatic Chi-square Interaction Detection (CHAID) method was used to identify health behaviours that contribute to a better adherence to the MD. Setting: Eight public secondary schools, in Algarve, Portugal. Participants: Adolescents with ages between 15 and 19 years (n 325). Results: According to the KIDMED index, we found a low adherence to MD in 9·0 % of the participants, an intermediate adherence in 45·5 % and a high adherence in 45·5 %. Participants that regularly have breakfast, eat vegetable soup, have a second piece of fruit/d, eat fresh or cooked vegetables 1 or more times a day, eat oleaginous fruits at least 2 to 3 times a week, and practice sports and leisure physical activities outside school show higher adherence to the MD (P < 0·001). Conclusions: The daily intake of two pieces of fruit and vegetables proved to be a determinant health behaviour for high adherence to MD. Strategies to promote the intake of these foods among adolescents must be developed and implemented. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the effectiveness on lifestyle change of an mHealth intervention to promote healthy behaviours in adolescence (TeenPower) and to analyse the predictors of the mHealth intervention effectiveness. Design: This study is designed as a non‐randomized controlled trial with a two‐arm structure. Methods: Adolescents of 12–16‐year old were recruited from three school districts, with access to the Internet and smartphone/tablet devices. The intervention group was invited to engage in the mHealth intervention (TeenPower) for 6 months in addition to a school‐based intervention. The control group only followed the school‐based intervention. A repeated measures factorial ANOVA was used and the main effectiveness outcome was the lifestyle change measured by the adolescent lifestyle profile. Results: The outcomes of the mHealth intervention (TeenPower) show a significant effect on nutrition (ƞ2p = 0.03, p =.03), positive life perspective (ƞ2p = 0.04, p =.01), and global lifestyle (ƞ2p = 0.02, p =.05), with a dropout rate of 62.1%. The analysis of the effectiveness predictors of the mHealth intervention suggested that older adolescents tended to show a significant increase in the rates of stress management (r =.40; p <.05). Conclusions: Although the considerable dropout rate, the mHealth intervention presented significant impact on multiple lifestyle domains, providing support for the effectiveness of mHealth interventions for health promotion as an add‐on to standard interdisciplinary interventions. Impact: Adolescents must have the necessary and appropriate knowledge for the correct and responsible decision‐making regarding their health and lifestyle. Innovative strategies (mHealth intervention) were used to promote healthy behaviours. This study evaluates the effectiveness of an mHealth intervention (TeenPower) specifically designed for adolescents. We found a significant impact in several lifestyle domains such as health responsibility, nutrition, positive life perspective, and global lifestyle. [ABSTRACT FROM AUTHOR]

Objectives Tobacco and excessive alcohol consumption are addictive behaviours, listed among the 10 leading risk factors that cause death and disability in the world, and health consequences are greater if their consumption is combined. There is sparse empirical evidence on the variables that influence the simultaneous consumption of tobacco and alcohol. This study aims to identify the variables that influence the joint decision to consume alcohol and tobacco, and that encourage drinkers to smoke. Study design The sample includes Portuguese adults, mainly aged 50 years and over, extracted from the Survey of Health, Ageing and Retirement in Europe, covering the year 2011. Methods We propose a bivariate probit model, which allows us to model simultaneously the two goods, accounting for potential correlation between smoking and drinking decisions. Results We identified the variables that influence joint consumption, and tobacco consumption among drinkers, which could be used as policy instruments to develop concerted policies. Prevention policies should focus on males, younger and more educated individuals, as well as on individuals with unhealthy eating habits, because these variables were statistically significant and increased joint consumption. In addition, these characteristics also should be regarded if we want to control tobacco consumption among alcohol consumers. Conclusions The analysis of the interdependence between alcohol and tobacco use presented in this article may allow reducing their consumption with a common intervention, enabling policymakers to 'kill two birds with one stone' and to achieve extended health and economic gains.

im: The aims of this study were to identify clustering of behaviours in young adolescents and to analyse differences in food intake according to clusters. Subject and methods: A cross-sectional study was carried out on adolescents' behaviours comprising 2,160 adolescents aged 13 years attending schools of Porto, Portugal. We used data of 875 girls and 737 boys with complete information for all variables considered in the cluster definition (tobacco and alcohol use, sport activities, fruit intake, daily sleep hours). The average method was used to find the natural structure of clusters. Results: We identified three clusters: cluster 1 characterized by never smokers and never drinkers represented those with higher intake of fruits and lower intake of soft drinks. Cluster 2 comprised essentially tobacco and alcohol experimenters and was almost similar to cluster 1 regarding the other characteristics. Cluster 3 represented mostly regular smokers and drinkers, and those with the lowest daily sport activities, the lowest number of daily sleep hours, the lowest mean of fruit consumption and the highest intake of sweets and soft drinks. Conclusion: Our findings show that even in the early stages of adolescence there is a cluster of smoking, alcohol use and food intake, providing further evidence of the clustering of unhealthy behaviours.

Abstract: Objective. The purpose of this study was to estimate the frequency and to assess the determinants of physical fighting among Portuguese school-going adolescents. Methods. A cross-sectional evaluation of urban adolescents born in 1990 and enrolled in public and private schools of Porto was performed in 2007. We identified 3,161 17-year-old eligible adolescents and 73.3% accepted to participate. Information was collected using a self-administered questionnaire assessing socio-demographic, behavioural, family and health-related characteristics. The magnitude of the associations between those characteristics and physical fighting was estimated using logistic regression. Results. Overall, 33.8% of adolescents (48.6% of boys and 20.1% of girls; p <0.001) engaged in a physical fight during the previous 12months. The school premises were the most frequently reported setting where fights occurred (girls–41.2% and boys–46.7%, p =0.179). After adjustment, and in both genders, we found statistically significant associations between physical fighting and grade retention, smoking, drinking and age at first sexual intercourse. Conclusion. Physical fighting among school-going adolescents is frequent, tends to occur at school premises and to cluster with other well recognized adverse health behaviours.

Objectives: To analyse the prevalence and association between metabolic syndrome (MetS), clustered cardiometabolic risk (CCMR), obesity (body mass index [BMI], fat mass [FM] and waist circumference [WC]), and cardiorespiratory fitness (CRF); and to assess whether obesity (BMI, FM, and WC) acts as a mediator between CRF and MetS or CCMR., Methods: This cross-sectional study included a subsample of the AFINA-te Study (n = 209; 11.51 ± 0.72 years old). BMI, FM, and WC were assessed. The Course-Navette test was used to assess CRF. MetS was calculated following the International Diabetes Federation (IDF) definitions, and assessed using WC, triglycerides (TGs), high density lipoprotein (HD), fasting glucose (FG), and systolic and diastolic blood pressures (SBP/DBP). CCMR was calculated based on the sex and age-specific z score., Results: The prevalence of overweightness, obesity, MetS, and CCMR were 17.22, 1.44, 5.74, and 18.36%, respectively. After including BMI, FM, or WC into the model, the association between CRF and MetS was no longer significant, and the association between CRF and CCMR was only significant when it was mediated by BMI (β = -0.006; p = 0.026). The rest of the analysis of the mediation did not show a direct effect, although a significant indirect effect with a significant value for the Sobel test was observed (all p < 0.001)., Conclusions: BMI, FM, and WC act as full mediators in the association between CRF and MetS; FM and WC act as full mediators in the association between CRF and CCMR; and BMI acts as a partial mediator. The use of FM or WC as obesity variables is recommended., (© 2021 Walter de Gruyter GmbH, Berlin/Boston.)

Objectives: Self-rated health (SRH) and health-related quality of life (HRQoL) are related with health outcomes. It is expected that these constructs are also associated with healthy behaviours. Thus, the present study sought to analyse the associations between a healthy lifestyle composite score and SRH and HRQoL among adolescents., Study Design: This was an observational, cross-sectional study., Methods: Data were obtained from the cross-sectional health behaviour in school-aged children (HBSC) 2014 Portuguese survey. Participants were 5024 adolescents (2373 boys), aged 10-17 years. A composite score of healthy lifestyle was obtained using the combination of the following factors: daily physical activity, sleep at least 8-9 h/night, daily consumption of fruit and vegetables, spend <2 h daily in screen-based behaviours, never drink and never smoke., Results: Adolescents with a healthy lifestyle had significantly better SRH and higher HRQoL than those who were not engaged in all healthy behaviours., Conclusions: Healthy lifestyle (composed of physical activity, sleep at least 8-9 h/night, daily consumption of fruit and vegetables, spend <2 h daily in screen-based behaviours, never drink and never smoke) is related to SRH and HRQoL. Promoting a comprehensive approach to these behaviours is a public health strategy to be considered when aiming to improve health, in general, and SRH and HRQoL, in particular., (Copyright © 2019 The Royal Society for Public Health.

Introduction: Problems concerning occupational safety and health are commonly found in the construction industry, including falling materials, tools or people from a height, stepping on objects, and injuries caused by hand tools. An important factor in occupational safety in the construction industry is the use of scaffolds. All scaffolds used in construction, renovation, repair (including isolating, painting and decorating) and demolition, should be erected, maintained and dismantledin accordance with safety procedures. Therefore, it is crucial to deal with the safety of scaffolds and risk assessment in the construction industry; thus, the way of undertaking the assessment and the liability of assessment seems to be essential for professionals. However, it has been found that those professionals are prone to rely heavily on their own experience and knowledge in decision-making regarding risk assessment., Material and Methods: The Scaffold Use Risk Assessment Model (SURAM) has been developed for assessing risk levels at various stages of the construction process in various work trades. The SURAM is the result of a research project carried out at 60 construction sites in Poland and Portugal where 504 observations have been completed including both harmful physical and chemical factors, stress level, workers' habits, as well as a hundreds ex-post reconstruction of construction accidents scenarios., Results: It was found that the workers' Health Behaviour Index (HBI) seems to be a more direct predictor for development of the unsafe chain of events leading to an accident than the workload, and concentration of harmful factors at the workplace., Conclusions: The developed HBI module of SURAM seems to be beneficial for predicting high-risk construction activities, and thus preventing the occurrence of accidents, based on a set of historical accident data.
