Physical activity and stroke among women - A non-linear relationship.
Studies have identified non-linear inverse relationships between physical activity and the risk of stroke. A U-shaped response has been observed between haemorrhagic stroke and physical activity. The objective of this study was to investigate the associations between physical activities on stroke. ⋯ High-intensity activities were associated with a U-shaped response for haemorrhagic stroke types. Low-intensity activities were associated with a linear response for all stroke types. Our results support other observations that physical activity may reduce stroke risk.

The adherence to school meals is associated with a lower occurrence of obesity among Brazilian adolescents.
This study aimed to verify the association between adherence to meals from the Brazilian National School Feeding Program (PNAE) and obesity indicators among adolescents. Data from 12,373 students attending public schools from the 2015 National Survey of School Health were used. Adherence to school meals was assessed using a self-administered questionnaire and classified as null (zero/rarely), low (1-2×/week), moderate (3-4×/week), and high (5×/week). ⋯ An inverse and dose-response association were observed between adherence to the PNAE meals and obesity indicators. Adolescents with high adherence to school meals (5×/week) had a 0.10 lower BMI Z-score (coefficient = -0.10, CI -0.17;-0.03), 11% less prevalence of overweight (PR = 0.89, CI 0.80;0.99) and 24% less prevalence of obesity (PR = 0.76, CI 0.62;0.93) than those with a lower adherence (<5×/week). Our results showed that the adherence to PNAE meals may contribute to obesity prevention in Brazil.

Awareness of the link between human papillomavirus and oral cancer in UK university students.
Awareness of the link between human papillomavirus (HPV) and oral cancer varies across populations. Levels of awareness and factors may impact HPV vaccine uptake in women and the intent to obtain the vaccine in men if it becomes available. A cross-sectional survey of 1415 UK university students (495 men and 920 women) aged 18-25 years was conducted. ⋯ However, being aware was associated with HPV vaccine uptake in women (aOR = 1.65; 95% CI: 1.19-2.28) and borderline associated with the intent to obtain the HPV vaccine in men (aOR = 1.52; 95% CI: 0.99-2.35). Non-heterosexual men were more willing than heterosexuals to receive the vaccine. Following the UK gender-neutral HPV vaccination programme, there is an opportunity to increase awareness about the link between HPV and oral cancers aside from the cervical cancer link to influence HPV vaccine uptake.

Active transportation and social capital: The association between walking or biking for transportation and community participation.
Active transportation provides benefits to communities and individuals, yet little is known about its relationship with social capital. This study examined relationships between active transportation behavior and three indices of social capital (community participation, sense of community, and sociopolitical control). Linear regression was used to assess cross-sectional data (N = 1700) from the Survey of the Health of Wisconsin, a population-based representative sample collected in 2014, 2015, and 2016. ⋯ All models controlled for confounding background characteristics. These findings are important for policy and planning work, as designing supportive environments and removing barriers to active transportation can foster social capital through bolstering community participation. The benefits of active transportation may be broader than previously understood and underscore the need to promote active transportation.

Sociodemographic and psychological characteristics associated with discrepancy between body satisfaction and weight change among adolescents.
This study aimed to describe the discrepancy between body satisfaction change and weight change among adolescents following a 2-year school-based intervention, to identify associated sociodemographic factors, and to explore possible associations with perceived health indicators. We used data from a northeastern France representative adolescents sample (14-18 years old) who participated in the PRALIMAP (PRomotion de l'ALIMentation et de l'Activité Physique) study (2006-2009). Weight change was measured by the change in body mass index z-score from the start to the end of the study. ⋯ Body satisfaction change was rather in line with anxiety, depression and quality of life changes than weight change. Body satisfaction change should be considered in overweight and obesity prevention interventions alongside body weight change, and could be used as indicator of long-term behavior maintenance. Clinical trials registry and number:ClinicalTrials.gov (NCT01688453).
