Substance use and deaths by suicide: A latent class analysis of the National Violent Death Reporting System.
Substance use is strongly associated with suicide completions. However, little is known about the patterns of substances used in suicide deaths. The purpose of this analysis is to determine latent classes of toxicology-reported substances among individuals who completed suicide. ⋯ Homelessness was associated with classification in the "Marijuana and other substance" class and the "Opiate use" class compared to the "No substance/single substance" class. IPV was associated with both polysubstance use classes ("Alcohol plus other substance" and "Marijuana plus other substance") along with the "Opiate use" class compared to the "No substance/single substance" class. These classes highlight profiles of suicide descendants and emphasize the importance of polysubstance use prevention among females, homeless individuals, and those who experience IPV.

Combined patterns of participation in cervical, breast, and colorectal cancer screenings and factors for non-participation in each screening among women in Japan.
Finding effective strategies to increase participation in cervical cancer screening (CCS), breast cancer screening (BCS) and colorectal cancer screening (CRCS) for women is an important public health issue. Our objective was to examine combined patterns of participation in these three screenings and investigate the factors associated with non-participation in each. We analyzed 115,254 women aged 40-69 who were age-eligible for all three screenings from a 2016 nationally representative cross-sectional survey in Japan. ⋯ Unstable employment, low educational attainment, low self-rated health, and current smoker were associated with both non-participation and partial-participation, especially single-participation in cervical and breast cancer screening. For example, self-employed women were more likely to be non-participants [aOR 2.80 95%CI: 2.65-2.96], single-participants for CCS [aOR 2.87 95%CI: 2.57-3.20], and BCS [aOR 2.07 95%CI: 1.85-2.33] than permanent workers. It may be useful to consider related factors for non-participation patterns to encourage partial-participants to have other cancer screenings by utilizing one cancer screening as an opportunity to provide information about other screenings.

Identifying message themes to prevent e-cigarette use among youth and young adults.
In 2020, almost 20% of high school students reported current e-cigarette use. Mass media tobacco prevention campaigns are effective for preventing tobacco use among youth and young adults but selecting messages that will have maximum impact on the target audience is a significant challenge for campaign developers. This study describes the method for identification of potential messaging targets for a national anti-vape mass media campaign using criteria proposed by Hornik and Woolf in their health communication framework. ⋯ The resulting items targeted five potential message themes, each forming a scale measured with three to four individual items. Message themes included social acceptability of vaping, anti-vape industry sentiment, independence from vaping, non-vaping identity, and perceived risk of harm. Findings were used to inform the development of truth® campaign messaging focused on reducing the prevalence of e-cigarette use among youth and young adults.

The impact of a universal human papilloma virus (HPV) vaccination program on lower genital tract dysplasia and genital warts.
Assess Ontario's school-based human papillomavirus (HPV) vaccination program on reducing rates of cervical dysplasia, colposcopy services and treatment for genital warts, cervical conization, cryotherapy and laser vaporization of the lower genital tract. Women born in 1995 in Ontario, Canada were the first cohort of students to receive the vaccine. We followed these women from age 18-23 and identified pap test cytology results, referral and attendance at colposcopy, treatment of HPV related warts and treatment of lower-genital tract dysplasia using administrative databases. ⋯ The relative risk of requiring colposcopy if unvaccinated was 1.94 and they were 6.15 times more likely to require treatment. There were no differences between socio-economic groups and geographic regions. Vaccination programs are effective at decreasing rates of cervical dysplasia, lead to reduced need for colposcopy, treatment of HPV related warts and pre-invasive disease even at early ages.
