Meta AnalysisHow effective are digital technology-based interventions at promoting colorectal cancer screening uptake in average-risk populations? A systematic review and meta-analysis of randomized controlled trials.
Despite the global prevalence of colorectal cancer (CRC) and efforts in screening advocacy, screening uptake remains relatively low. Considering the greater accessibility and popularity of telemedicine in behaviour change interventions, this meta-analysis seeks to examine the usefulness of digital interventions in promoting CRC screening uptake as compared to existing non-digital strategies. A systematic search on five databases identified articles published before September 2022. ⋯ Meanwhile, the tailored educational intervention subtype failed to achieve statistical significance in promoting screening uptake, bearing in mind the significant heterogeneity across studies (I2 = 88.6%). Digital decision-making aids significantly improved CRC screening uptake compared to tailored digital educational interventions and usual care. However, as all included studies were conducted in Western settings, its role in augmenting existing CRC screening promotion strategies especially among Asians should be further evaluated.

ReviewAre the adverse health effects of air pollution modified among active children and adolescents? A review of the literature.
Air pollution exposure is associated with negative health consequences among children and adolescents. Physical activity is recommended for all children/adolescents due to benefits to health and development. However, it is unclear if physically active children have additional protective benefits when exposed to higher levels of air pollution, compared to less active children. ⋯ However, the remaining two EMM studies highlighted modest benefits of having a higher activity level, even in polluted air. Overall, active children/adolescents may be at greater risk from air pollution exposure, but results were not consistent across all studies. Future studies assessing the intersection between air pollution and regular physical activity among children would be useful.

ReviewThe effectiveness of health education interventions on cervical cancer prevention in Africa: A systematic review.
Low levels of knowledge and awareness on cervical cancer play a role in limiting cervical cancer prevention uptake. This systematic review aimed to identify effective educational interventions to increase cervical cancer awareness, knowledge, and subsequently screening or vaccination uptake in African women. A literature search was conducted in Medline and EMBASE databases. ⋯ Educational interventions increased knowledge and awareness in African women, some boosted uptake of cervical cancer screening, especially when using peer health educators and culturally tailored methods. Innovative approaches such as self-collected HPV testing and mHealth also demonstrated a potential to increase uptake of screening. More research is needed to identify and analyse barriers to screening uptake, which can still be present even after a successful educational intervention.

Body image distortion among Brazilian and Portuguese women with children: A comparative study between the ELSA-Brasil and Generation XXI cohorts.
Solid evidence indicates that body image distortion is associated with various physical and mental health problems in women (e.g. Lee and Lee, 2016; Mölbert et al., 2017; Raj and Ploriya, 2020; Sagar, 2005; Shin et al., 2015). Furthermore, body image has been shown to vary according to life context and stage, particularly after a woman has had children. ⋯ In cases of distorted self-perception, the likelihood of the Brazilian women perceiving themselves as being heavier was greater if they had had cancer, whereas the Portuguese women were less likely to perceive themselves as heavier when they had less schooling. Perceiving themselves as thinner than they actually are, was associated with poorer self-perception of their own state of health in the Brazilian women and with poorer schooling in both the Brazilian and Portuguese women. The present findings contribute towards improving understanding of the influence of body image distortion on the health and wellbeing of Brazilian and Portuguese women, possibly leading to the implementation of health-promoting policies in both countries.

Physical activity trajectories, autonomic balance and cognitive function: The Coronary Artery Risk Development in Young Adults (CARDIA) study.
Physical activity (PA) plays an important role in cognitive health. However, the underlying mechanisms are not fully understood. Cardiac autonomic balance is influenced by PA and implicated in dementia pathogenesis. ⋯ Meeting and exceeding MVPA guidelines were related to better autonomic balance overall, and to improved semantic fluency performance. Statistically, the association between higher MVPA level and verbal ability was mediated by SDNN and RMSSD, but not by RHR. In our sample of young and middle-aged adults, higher MVPA levels over time were associated with better cardiac autonomic function, which explained some of the associations between PA trajectories and better cognition.
