Males consumed more energy than did females across all pubertal stagesAfter adjustment for fat-free mass, fat mass, height, overweight status, race, and meal instruction, the main effect of sex ... remained significant, but the effect of puberty was not significantConsistent with their higher energy requirements, males can consume significantly larger amounts of food than females, especially during later puberty.
Analysis of the model showed a "perfect storm" of traits for children who are most likely to become hostile after playing violent video games, according to Markey. Those traits are: high neuroticism (e.g., easily upset, angry, depressed, emotional, etc.), low agreeableness (e.g., little concern for others, indifferent to others feelings, cold, etc.) and low conscientiousness (e.g., break rules, don't keep promises, act without thinking, etc.).The teenagers who were highly neurotic, less agreeable and less conscientious tended to be most adversely affected by violent video games, whereas participants who did not possess these personality characteristics were either unaffected or only slightly negatively affected by violent video games."Violent video games are like peanut butter," said Ferguson. "They are harmless for the vast majority of kids but are harmful to a small minority with pre-existing personality or mental health problems."
“We asked ourselves how many lives could we save if we simply did a better job of increasing the use of clinical preventive services,” said Thomas Farley, M.D., the study’s lead author. “The potential for prevention is big,” he said."They examined nine recommended types of preventive services, which included screening and treatment for high blood pressure and cholesterol levels, use of aspirin in people at high risk for heart disease, smoking cessation programs, cancer screenings and immunizations.""As many as 50,000 to 100,000 deaths in people under age 80 could be prevented each year if all of these preventive services were offered to and used by patients, the models suggested.""The message here is that there is “a lot of health benefit that is unrealized in America because we don’t do rather simple things that we can be doing to prevent disease or detect it at an early or treatable stage,” Schwartz said."
"Four unhealthy behaviors -- smoking, lack of physical activity, poor diet and alcohol consumption -- appear to be associated with a substantially increased risk of death when combined...""When compared with participants who had no poor health behaviors, the risk of death from all causes and from each cause increased with each additional behavior.""Individuals with four compared with zero poor health behaviors had about three times the risk of dying of cardiovascular disease or cancer, four times the risk of dying from other causes and an overall death risk equivalent to being 12 years older."
"Teachers have an effect on student reading achievement," said psychology Associate Professor Jeanette Taylor, the study's lead author. "Better teachers provide an environment that allows children to reach their potential.""When children receive more effective instruction, they will tend to develop at their optimal trajectory," Taylor said. "When instruction is less effective, then children's learning potential is not optimized and genetic differences are left unrealized."The authors cautioned that other factors, such as classmates, resources and the physical classroom itself, might also influence the level of reading achievement among young students. However, this study clearly underscores the importance of teachers."Putting high quality teachers in the classroom will not eliminate variability among students nor guarantee equally high achievement from all children, but ignoring teachers as a salient contributor to the classroom environment represents a missed opportunity to promote children's potential in school and their success in life," the researchers concluded.
Poverty influences a child's well-being through multiple environmental stressors ... remediable "material hardships" that may have direct physiologic impacts on children. These hardships include food insecurity (lack of access to enough healthful food for an active healthy life) housing insecurity (unstable or overcrowded housing) and energy insecurity (inability of families to afford consistent home heating or cooling).The researchers found that as scores on a cumulative index of the hardships increased in severity, the chances of young low- income children simultaneously experiencing normal growth, health, and development (which the investigators term "wellness") decreased ...... cumulative hardships--a diet of inadequate quality or quantity, temperature stress from lack of heat or cooling, and frequent moves or increased exposure to infectious disease and noise in crowded households--exert direct negative physiologic consequences on children.
Reducing the number of preventable patient injuries in California hospitals from 2001 to 2005 was associated with a corresponding drop in malpractice claims against physiciansResearchers studied both medical malpractice claims and adverse events such as post-surgical infections across California counties and found that changes in the frequency of adverse events were strongly correlated with corresponding changes in the volume of medical malpractice claims.These findings suggest that putting a greater focus on improving safety performance in health care settings could benefit medical providers as well as patients
Researchers tested selective attention with visual search tasks in participants in a shift work simulation, which included four day shifts followed by three night shifts. They found that attention during the first night shift was the most impaired, with participants unable to stay focused on tasks.
While most people derive pleasure and satisfaction from researching their ancestry, for some it brings to light "secrets and skeletons"Slightly over 13% of the people studied reported conflict resulting from genealogical researchThe main causes were: uncovering unwelcome information, wanting information from relatives who didn't wish to give it, giving relatives inaccurate information, spending more time researching than with loved ones, and coming into contact with hostile relatives.Dr Kramer noted that in most cases people wrote positively about researching their family's history. People found pleasure in making discoveries, investigating family myths and mysteries and making their ancestors real by finding out more about their lives. In some cases, the research could help mend rifts in families. However, not all experiences were entirely positive.
Changes in the alcohol consumption behavior of a person's social network had a statistically significant effect on that person's subsequent alcohol consumption behavior.The behaviors of immediate neighbors and coworkers were not significantly associated with a person's drinking behavior, but the behavior of relatives and friends was.People whose friends or relatives drank heavily were 50% more likely to also drink heavily compared to people who weren't connected with heavy drinkers.The researchers also found in general that being surrounded by heavy drinkers increased the reported alcohol consumption by about 70%, while being surrounded by abstainers decreased reported alcohol consumption by half.
As hypothesized, in most situations women more than men preferred dating and men more than women preferred hooking up.Women more than men seem to want a relationship. They fear, both in dating and hooking up, that they will become emotionally attached to a partner who is not interested in them.Men more than women seem to value independence. They fear that even in hooking up relationships, which are supposed to be free of commitments, a woman might seek to establish a relationship
