Review Meta AnalysisHow may we effectively motivate people to reduce the consumption of meat? Results of a meta-analysis of randomized clinical trials.
Excessive meat consumption (MC) is associated with multiple health risks. Additionally, it can undermine environmental sustainability and affect the potential improvement of animal welfare. The aim of this study was to assess the efficacy of literacy interventions (LIs) in reducing MC. ⋯ Informing about health risks related to MC temporarily decreased its intake, while informing about the impact on environmental sustainability or animal welfare was ineffective. Furthermore, long-lasting LIs achieve long-term dietary change toward MC.

Utilizing social determinants of health to identify most vulnerable neighborhoods-Latent class analysis and GIS map.
Public Health officials are often challenged to effectively allocate limited resources. Social determinants of health (SDOH) may cluster in areas to cause unique profiles related to various adverse life events. The authors use the framework of unintended teen pregnancies to illustrate how to identify the most vulnerable neighborhoods. ⋯ What is already known on this topic Public health practitioners struggle to develop interventions that are universally effective. The teen birth rates vary tremendously by race and ethnicity. Unplanned teen pregnancy rates are related to multiple social determinants and behaviors. Latent class analysis has been applied successfully to address public health problems. What this study adds While it is the pregnancy that is not planned rather than the birth, access to pregnancy intention data is not available resulting in a dependency on teen birth data for developing public health strategies. Using teen birth rates to identify at-risk neighborhoods will not directly represent the teens at risk for pregnancy but rather those who delivered a live birth. Since teen birth rates often fluctuate due to small numbers, especially for small neighborhoods, LCA may avoid some of the limitations associated with direct rate comparisons. The authors illustrate how practitioners can use publicly available SDOH from the Census Bureau to identify distinct SDOH profiles for teen births at the census tract level. How this study might affect research, practice or policy These profiles of classes that are at heightened risk potentially can be used to tailor intervention plans for reducing unintended teen pregnancy. The approach may be adapted to other programs and other states to prioritize the allocation of limited resources.

Changing eating to manage weight or shape: A cross-sectional and prospective study of the prevalence and correlates in a large Canadian adolescent cohort.
The present study examined reports of changing eating to manage weight/shape over one year among adolescents. It also tested how changing eating for weight/shape was associated with physical activity (resistance training, moderate-to-vigorous physical activity; MVPA) and mental health (depressive symptoms, flourishing), and whether weight perceptions moderated these associations. ⋯ Reports of changing eating to manage weight/shape were associated with divergent health outcomes; research into how and to what extreme adolescents are changing eating to manage weight/shape, and identity factors that may contribute to these differences, is warranted.
