Identifying patterns of movement behaviours in relation to depressive symptoms during adolescence: A latent profile analysis approach.
Movement behaviour guideline adherence has been associated with lower depressive symptoms during adolescence, yet no studies have used person-centered approaches to examine this relationship. The purpose of the present study was to identify whether unique adolescent movement behaviour profiles exist, evaluate predictors of profile membership, and determine whether profile membership was associated with differences in depressive symptoms cross sectionally and longitudinally. This study involved secondary analysis of the public-use data from Wave 1 and Wave 2 of the National Study of Adolescent Health. ⋯ After adjusting for covariates, findings revealed depressive symptoms were lowest among the high MVPA/low ST profile and this trend was evident one year later. Engaging in high levels of either MVPA or ST alone did not provide additive benefits for depressive symptoms compared to those who engaged in low levels of both MVPA and ST. These findings suggest intervention efforts should take an integrative approach to improve mental health outcomes among adolescents by considering each of the movement behaviours concurrently.

Comparative StudyImpact of COVID-19 lockdown policy on homicide, suicide, and motor vehicle deaths in Peru.
Although lockdown measures to stop COVID-19 have direct effects on disease transmission, their impact on violent and accidental deaths remains unknown. Our study aims to assess the early impact of COVID-19 lockdown on violent and accidental deaths in Peru. Based on data from the Peruvian National Death Information System, an interrupted time series analysis was performed to assess the immediate impact and change in the trend of COVID-19 lockdown on external causes of death including homicide, suicide, and traffic accidents. ⋯ The slope in homicide in men during the lock-down period increased by 6.66 deaths per million men per year (95% CI:3.18, 10.15). External deaths presented a sudden drop after the lockdown was implemented and an increase in homicide in men was observed. Falls in mobility have a natural impact on traffic accidents, however, the patterns for suicide and homicide are less intuitive and reveal important characteristics of these events, although we expect all of these changes to be transient.

Racial disparities in occupational risks and lung cancer incidence: Analysis of the National Lung Screening Trial.
The relationship between racial disparities in occupational risk and lung cancer diagnosis is not well defined. We examined occupational exposure to asbestos, silica, and other workplace chemicals, fumes, or dusts as reported in the National Lung Screening Trial (NLST). Descriptive analyses and multivariate logistic regression models were performed. ⋯ African-Americans had higher odds of lung cancer diagnosis than White individuals (aOR = 1.24 to 1.25, 95% CI = 1.01-1.54). Our findings indicate that we need more effective public health prevention programs, especially for minorities who may have disproportionately greater occupational exposures due to socioeconomic constructs and barriers. Interventions may include education about occupational risks and lung cancer screening or instituting workplace policies for smoke-free environments with tobacco cessation support.

Gunshot-victim cooperation with police investigations: Results from the Chicago Inmate Survey.
Just one in ten nonfatal shootings in Chicago lead to an arrest. Unlike in fatal cases, gunshot victims who survive can often provide information of use in the police investigation. Nonetheless, nonfatal shooting cases in Chicago and elsewhere have much lower arrest rates than fatal cases, in part because most victims do not cooperate. ⋯ In fact, victims were more likely to speak with the police when they did not have any information on their shooter. Respondents explained their choice not to cooperate by reference to "street codes" against snitching, mistrust of the police, and the desire to retaliate against the shooter personally. If more shooting victims could be persuaded to cooperate, the police could solve more cases and hence be more effective in curtailing gun violence.

E-cigarette susceptibility among U.S. middle and high school students: National Youth Tobacco Survey Data Trend Analysis, 2014-2018.
Youth e-cigarette use has rapidly increased in the last few years. Susceptibility is a validated measure associated with future tobacco use. We examined trends in e-cigarette susceptibility across five years (2014-2018) of the National Youth Tobacco Survey among youth e-cigarette never users. ⋯ This study is the first to document trends in e-cigarette susceptibility among youth. Understanding antecedents of e-cigarette use and identifying youth subgroups vulnerable to e-cigarette use is valuable to developing effective prevention efforts.
