A community-wide intervention to promote physical activity: A five-year quasi-experimental study.
Evidence on the effects of a community-wide intervention (CWI) on population-level physical activity (PA), especially in the long term, is limited. Therefore, we evaluated the five-year effect of CWI on promoting PA through information dissemination, education, and community support primarily targeting older adults, by incorporating Japanese guidelines, in Fujisawa City, from 2013. To assess the effect of the whole-city intervention, we distributed questionnaires in 2013, 2015, and 2018 to three independent random samples of 3,000 community-dwelling adults (aged ≥ 20 years) using a quasi-experimental study design. ⋯ Among older adults, PA was significantly lower in those with poorer perceived economic status than in their more well-off counterparts at the two-year follow-up (P= 0.003); however, there was no significant difference at the five-year follow-up (P= 1.000). There was a positive interaction between group and period (mean difference of change between groups: 40.9 minutes/day, P= 0.001). In conclusion, the five-year CWI targeting older adults, incorporating national guidelines, improved population-level PA.

Disparities in exposure to television advertising of sugar-sweetened and non-nutritive sweetened beverages among U.S. adults and teens, 2007-2013.
The objective of this study was to estimate disparities in exposure to television advertising of sugar-sweetened and non-nutritive sweetened beverages among U. S. adults and teens. Data (2007-2013) came from the National Consumer Survey and included 115,510 adult respondents (age 18+) and 8635 teen respondents (age 12-17). ⋯ Adult (teen) respondents who were non-white with low incomes and with low educational attainment were exposed to 4.7% (53.7%) more regular soda ads, 6.6% (43.8%) more diet ads, and 23.2% (56.2%) more energy/sport ads than respondents who were white with high incomes and high educational attainment. Demographic and socio-economic groups with a higher prevalence of obesity were exposed to significantly more advertisements for sugar-sweetened beverages. When evaluating potential policies to regulate marketing of sugar-sweetened and non-nutritive sweetened beverages, policymakers should consider the disparate exposure of at-risk populations to advertising of sugar-sweetened and non-nutritive sweetened beverages.

Trends in young adults' mental distress and its association with employment: Evidence from the behavioral risk factor surveillance system, 1993-2019.
Few have examined how employment is linked to trends in mental health among young adults across economic contexts in more recent years. To better understand the burden of non-employment and mental distress in this age group, this study examines the association of short-term (<1 year) and long-term (1+ year) out-of-work status with mental health across three recessions among young men and women ages 18-34. We report sex-stratified estimates of frequent mental distress (FMD), out-of-work status, and their association through adjusted prevalence ratios across 27 cycles of the U. ⋯ Short-term (PR men = 1.53, 95%CI 1.46-1.61; PR women = 1.34, 95%CI 1.29-1.40) and long-term (PR men = 1.61, 95%CI 1.51-1.71; PR women = 1.28, 95%CI 1.22-1.34) out-of-work status were each associated with a higher risk of FMD during this period. The magnitude of associations between long-term out-of-work status and FMD significantly varied across cycles, and was strongest after the 1991 recession in men and the 2008 recession in women. Whereas employment represents an important determinant of mental health among young adults, particularly during economic downturns, it did not suffice to explain the rise in mental distress in this age group in more recent years.

Beyond "Safe and Effective": The urgent need for high-impact smoking cessation medications.
Smoking cessation medications (SCMs) are an evidence-based cornerstone of comprehensive tobacco control programs globally. However, the impact of SCMs on population smoking prevalence is controversial, with inconsistencies between randomized controlled trials (RCTs) and population-based observational studies. We estimated SCM impact on permanent cessation and population smoking prevalence by extrapolating efficacy estimates from meta-analyses of RCTs, using the standard population impact formula: efficacy*reach. ⋯ Even under ideal conditions, the potential of current first-line SCMs to increase cessation in a substantial proportion of smokers, and reduce population smoking prevalence, is limited. In order to avert the predicted billion tobacco-caused deaths in this century, "safe and effective" medications are not sufficient: SCMs with high population impact are urgently needed. Policies to ensure the availability and accessibility of highly efficacious SCMs, with behavioral support, are crucial.

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.
