Background: Dual process models characterize hazardous drinking as a function of appetitive processes and executive processes that enable self-control. Although central to a number of models (e.g., Hofmann et al., 2009a,b), little empirical research has examined how drinking restraint may influence the effects of these processes on alcohol use. The current study examined whether drinking restraint influenced the predictive value of appetitive responses to alcohol cues and executive functioning on typical drinking behavior. It was hypothesized that the interaction between appetitive responses and executive functioning would only be observed among those who had stronger drinking restraint goals.
Methods: Sixty-nine hazardous drinking young adults (ages 21-30) completed the Trail Making Test and then were exposed to the sight and smell of an alcoholic beverage that they anticipated they would consume. Urge and anticipated stimulant effects of alcohol (A-BAES) were measured following the exposure.
Results: The interaction between Trails B and each of the appetitive response ratings (i.e., urge rating and A-BAES) was predictive of drinking behavior (TLFB) only among those high in drinking restraint.
Conclusions: These findings highlight the importance of incorporating the role of motivational constructs such as restraint goals in current dual process models of alcohol-related self-control.

We present the recommendations of the Preventive Activities and Health Promotion Programme (PAPPS) of the semFYC (Spanish Society of Family and Community Medicine) to promote healthy lifestyles using intervention methodology, and preventive actions against tobacco and alcohol use, healthy eating, physical activity in leisure time, prevention of traffic accidents, and child restraint systems. The recommendations have been updated, and new aspects highlighted, such as the definition of low-risk alcohol consumption, and the references have been updated. For the main recommendations, we include specific tables showing the quality of the evidence and the strength of the recommendation.

: Problematic eating behaviours may affect food consumption and, therefore, body weight. However, these associations have not been well understood, especially among adolescents. The aim of the study was to evaluate the associations of restrained eating and disinhibited eating with diet quality and body weight status among adolescents.

Article Synopsis
- Adolescent stress and alcohol exposure can lead to increased risk of mental disorders in adulthood, with notable differences between males and females in their responses.
- The study involved male and female rats subjected to stress and alcohol to evaluate hormonal and genetic changes, revealing sex-specific responses in hormones like ACTH and CORT, and gene expressions related to stress response.
- Key findings included that stressed males had lower alcohol levels, females had heightened ACTH under stress, and distinct patterns in hormonal changes and gene expression between sexes were observed, indicating the complexity of their interactions.
Alcohol use, civilian interference, and other possible risk factors for death during restraint.

Article Synopsis
- Physical restraint is often used to manage violent situations, and various factors contribute to aggressive behavior, which can be identified through medical records or forensic autopsies.
- This study reviewed 21,036 forensic autopsy cases from Southern Finland (2010-2015) and found 12 instances (0.06%) where physical restraint was used before death, highlighting the involvement of police and civilians in these incidents.
- Civilians were more likely to be associated with death resulting from restraint, potentially due to a lack of training in safe methods and the influence of alcohol, which poses additional risks for both aggressive behavior and fatal outcomes.
Risk and Protective Factors for Injury in Adult Front- and Rear-Seated Motor Vehicle Occupants in New York State.

Article Synopsis
- Seatbelt use significantly reduces the risk of injury and death in vehicle crashes, but rear-seated adults are less likely to wear them compared to those in the front seat.
- A study analyzed data from nearly 1 million adults involved in crashes in New York, finding that rear-seated occupants had a 1.5 times higher mortality rate and were more often unrestrained.
- Factors like speeding, a drinking driver, and older vehicles were linked to higher injury severity, highlighting that unrestrained rear-seated occupants face greater risks than their restrained front-seated counterparts.
