African American adolescent girls have evidenced higher levels of disruptive behavior than girls from other ethnic groups. However, most research focused on understanding disparities in these outcomes has been conducted without consideration of gender or has focused exclusively on boys. Yet, prior research suggests that anger and aggression are less gender-typed in African American youth than they are among youth from other ethnic backgrounds.

Since its development in the late 2000s, the ISF has been supported by federally funded centers for SMH and PBIS, and, guided by a national workgroup, is being implemented in >50 communities in the United States. This experimental evaluation of the ISF involved an RCT implemented in 24 schools in two southeastern states, with the ISF implemented in eight schools, PBIS alone implemented in eight schools, and typically co-located PBIS+SMH implemented in eight schools.

- - DietCompLyf is a study involving 3,159 women with grades I-III breast cancer across 56 UK hospitals, aiming to explore links between phytoestrogens (plant compounds with estrogen effects) and breast cancer recurrence and survival.
- - Participants provided detailed data on their health, diet, lifestyle, and quality of life for up to five years after diagnosis, with a focus on phytoestrogen intake assessed through a comprehensive food frequency questionnaire.
- - While certain patterns of phytoestrogen intake were noted (like younger patients consuming more isoflavones), no clear associations were found between their intake and better breast cancer prognosis, highlighting potential areas for further research.
The diagnosis of cancer can motivate survivors to alter their lifestyle habits. Healthcare providers need to be aware of what changes patients are likely to make in order to derive more pertinent recommendations; however, few studies have reported pre- and post-diagnostic lifestyle behaviours. Semi-quantitative food frequency questionnaires (FFQs) completed approximately 1 year after diagnosis were used to evaluate dietary intake and supplement use before and after diagnosis in a cohort of 1,560 breast cancer patients participating in the UK, prospective DietCompLyf study.
