Randomized Controlled TrialNatural American Spirit's pro-environment packaging and perceptions of reduced-harm cigarettes.
Natural American Spirit (NAS) cigarettes feature a pro-environment marketing campaign on the packs. The NAS "Respect for the Earth" campaign is the first example of on-the-pack corporate social responsibility advertising. In a randomized survey design, we tested perceptions of NAS relative to other cigarette brands on harms to self, others, and the environment. ⋯ The NAS advantage was significant irrespective of smoking status, pack color, and brand order, with findings stronger for current than never smokers. Pro-environmental marketing on NAS cigarette packs contributes to misperceptions that the product is safer for people and the environment than other cigarettes and made by a company that is more socially responsible. Stricter government regulations on the use of pro-environment terms in marketing that imply modified risk are needed.

Comparative StudyA gender-stratified, multilevel latent class assessment of chronic disease risk behaviours' association with Body Mass Index among youth in the COMPASS study.
This paper sought to examine chronic disease risk behaviour latent classes and their association with Body Mass Index (BMI), assessing for gender differences. Participants were youth (n = 116,086; grades 9-12) enrolled in the COMPASS study (Ontario, Canada) during 2013, 2014, 2015. Multilevel latent class analysis was used to identify underlying, homogenous classes of youths' engagement in physical activity, smoking, binge drinking and marijuana use. ⋯ As such, youth in latent classes with substance use are associated with higher BMI and weight status. Successful interventions may include school policies/programs that limit screen time use, as they were seen to have a positive effect on PA engagement and including social-influences approaches for substance use. Future research and interventions should be gender-specific as our results show that different latent classes are associated with obesity across genders.

Prospective associations of happiness and optimism with lifestyle over up to two decades.
Greater levels of psychological well-being are associated with reduced disease and mortality risk, and lifestyle habits may be potential mechanisms underlying these relationships. Prospective studies show that positive psychological factors enhance the likelihood of adopting specific health behaviors; yet, whether they promote the adoption of multiple healthy behaviors, which can have a multiplicative effect on disease and mortality risk compared to individual behaviors, is unknown. We investigated whether happiness and optimism were related to a healthy lifestyle (characterized by multiple health behaviors) over 10-22 years of follow-up; we also explored bidirectional associations, assessing if a healthy lifestyle at baseline was related to greater likelihood of experiencing higher happiness and optimism over time. ⋯ In secondary analyses, the magnitude of the inverse association was somewhat smaller (likelihood of sustaining higher happiness levels for baseline healthy versus unhealthy lifestyle, RR = 1.11, CI = 1.10-1.12). Results were similar when considering optimism as the exposure and in other secondary analyses (e.g., across individual habits). While bidirectional associations are apparent, these findings suggest pursuing happiness and optimism as modifiable determinants of lifestyle deserves further consideration.

Cognitive resources moderate the adverse impact of poor perceived neighborhood conditions on self-reported physical activity of older adults.
Poor neighborhood conditions are associated with lower levels of physical activity for older adults but socio-ecological models posit that physical activity depends on both environmental and individual factors. Older adults' ability to overcome environmental barriers to physical activity may partially rely on cognitive resources. However, evidence on the moderating role of these cognitive resources in the associations between environmental barriers and physical activity is still lacking. ⋯ Participants with lower cognitive resource scores showed lower odds of engaging in physical activity when neighborhood conditions were poorer, whereas these conditions were not related to this engagement for participants with higher cognitive resource scores. These findings suggest that cognitive resources can temper the detrimental effect of poor neighborhood conditions on physical activity. Public policies should target both individual and environmental factors to tackle the current pandemic of physical inactivity more comprehensively.

Comparative StudyPersonality traits and preventive cancer screenings in the Health Retirement Study.
The Five-Factor model of personality has been associated with a wide range of health behaviors and health outcomes. However, few studies have examined whether personality traits are related to cancer screening in older adults. The present study investigated the cross-sectional associations between personality traits and the probability of obtaining a recent preventive screening for breast, cervical, prostate, and colorectal cancer. ⋯ The effect sizes were in the range of a 10-20% higher likelihood of cancer screening for 1 SD difference in personality. The present findings suggest that conscientiousness and extraversion were related to preventive cancer screenings, whereas neuroticism, openness and agreeableness were largely unrelated to the likelihood of such screenings. If these results are further replicated, health policy makers may consider personality traits when planning and implementing screening recommendations to improve preventive medicine.
