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
