Smoking during pregnancy may affect grandchildren's growth

Mon, 2014-08-18 09:32
Smoking during pregnancy has discernible effects on the growth of a woman's future grandkids, a new study shows. The "likely transgenerational effects from the grandmothers' smoking in pregnancy need to be taken into account in future studies of the effects of maternal smoking on child growth and development. If replicated, such studies could be a useful model for the molecular analysis of human transgenerational responses," said the senior author.

Brain imaging shows brain differences in risk-taking teens

Fri, 2014-08-15 08:23
Brain differences associated with risk-taking teens have been investigated by researchers who found that connections between certain brain regions are amplified in teens more prone to risk. "Our brains have an emotional-regulation network that exists to govern emotions and influence decision-making," explained the study's lead author. "Antisocial or risk-seeking behavior may be associated with an imbalance in this network."

Mass layoffs linked to increased teen suicide attempts

Thu, 2014-08-14 17:19
Mass layoffs trigger increased suicide attempts and other suicide-related behaviors among some teenagers, especially black teens, says new research. When 1 percent of a state's working population lost jobs, suicide-related behaviors increased by 2 to 3 percent among girls and black adolescents in the following year. Among girls, thoughts of suicide and suicide plans rose. Among black teens, thoughts of suicide, suicide plans and suicide attempts all increased.

Wed, 2014-08-13 11:20
The latest research on sports concussions in teens has been the focus of recent study. "We discovered a bidirectional relationship between both emotional symptoms developing in conjunction with physical symptoms, and also emotional symptoms developing because of the physical symptoms," said one researcher. In other words, "this research gives us a better understanding of the interaction between physical and emotional symptoms in concussion and will allow us to explore ways to help adolescents recover in a more timely fashion."

School violence, gun-related injury among top 10 child health concerns across U.S.

Mon, 2014-08-11 10:41
Childhood obesity remains the top health concern for children in 2014, but when asked about national concerns, adults put school violence and gun-related injuries in the top 10. In the poll's annual top 10 list, a nationwide sample of adults were asked to identify the biggest health concerns for kids in their communities, as well as kids nationwide. Overall, childhood obesity is rated at the top of both lists: 29 percent of adults said obesity is a 'big problem' for children in their local communities and 55 percent said it is 'big problem' across the country.

Sat, 2014-08-09 12:14
Frequent marijuana use can have a significant negative effect on the brains of teenagers and young adults, including cognitive decline, poor attention and memory, and decreased IQ, according to psychologists. "It needs to be emphasized that regular cannabis use, which we consider once a week, is not safe and may result in addiction and neurocognitive damage, especially in youth," said one expert.

Parents part of problem in distracted teen driving, study finds

Fri, 2014-08-08 09:00
Parents play a direct role in distracted teen driving, with more than half of teens talking on cellphones with their mother or father while driving, according to new research. "Teens said parents expect to be able to reach them, that parents get mad if they don't answer their phone and they have to tell parents where they are," said one investigator.

Aggressive behaviour increases adolescent drinking, depression doesn't

Wed, 2014-08-06 07:47
Adolescents who behave aggressively are more likely to drink alcohol and in larger quantities than their peers, according to a recent study completed in Finland. Depression and anxiety, on the other hand, were not linked to increased alcohol use. The study investigated the association between psychosocial problems and alcohol use among 4074 Finnish 13- to 18-year-old adolescents.

More than threefold surge in number of male teens drinking alcohol in India

Tue, 2014-08-05 20:12
The proportion of men who start to drink alcohol in their teens has surged more than threefold over the past few decades in India, suggests research. Those living in urban areas and poorer households are more likely to start drinking at an early age, the findings show. These findings highlight the importance of generating public awareness about the hazards of starting to drink early in life, and of enforcing regulations designed to limit underage drinking.

Risk drinking before pregnancy can increase the risk of the development behavioral problems in toddlers. Early intervention to help and support mothers and their children could help to prevent these problems from developing into long term behavioral problems.

Potential new predictor of stress-related illnesses found

Mon, 2014-08-04 08:06
Many scientists believe that the tendency to develop stress-related disorders is an inherited trait or is the result of exposure to traumatic events. In a new paper, scientists explain that a new factor -- that genes may change over time -- could cause depression, post-traumatic stress disorder and other stress-related illnesses.

Becoming bad through video games: Risk-glorying video games to increases in teens' high-risk behavior

Mon, 2014-08-04 08:03
Previous studies show that violent video games increase adolescent aggressiveness, but new research finds for the first time that teenagers who play mature-rated, risk-glorifying video games are more likely subsequently to engage in a wide range of deviant behaviors beyond aggression, including alcohol use, smoking cigarettes, delinquency and risky sex.

Toward a home test for detecting potentially dangerous levels of caffeine

Wed, 2014-07-30 07:43
The shocking news of an Ohio teen who died of a caffeine overdose in May highlighted the potential dangers of the normally well-tolerated and mass-consumed substance. To help prevent serious health problems that can arise from consuming too much caffeine, scientists are reporting progress toward a rapid, at-home test to detect even low levels of the stimulant in most beverages and even breast milk.

Teen insomnia linked with depression, anxiety

Wed, 2014-07-30 07:35
A study of high school students has shed new light on the links between insomnia-related mental health conditions among teens. "People with insomnia find it difficult to fall asleep or stay asleep for as long as they need to. This is a widespread sleep disorder among the general public, and in most countries about 11% of teens aged 13-16 years experience insomnia at some stage," one researcher said.

Strategies identified to improve oral contraceptive success with obese women

Mon, 2014-07-28 11:09
Two ways to effectively address the problem that birth control pills may not work as well in obese women, compared to women of a normal body mass index, have been proposed by researchers: either a higher-dose pill or skipping the 'one week off' regimen might work. For obese women, simply shifting to an alternative form of birth control is an option, the researchers said. But they also pointed out that oral contraceptives are the most preferred form of birth control and that a woman's individual preference influences her adherence and continuation with any method.

High school students in some schools smoking at same rate as adults

Thu, 2014-07-24 10:36
Cuyahoga County high school students are smoking tobacco products at the same rate as adults in the county, according to new data. In 2013, more than 22 percent, or one in five high school students, report use of any tobacco product within the prior 30 days.

Natural-terrain schoolyards reduce children's stress, says study

Tue, 2014-07-22 08:24
Playing in schoolyards that feature natural habitats and trees and not just asphalt and recreation equipment reduces children's stress and inattention, according to a study.

Adolescent alcohol abuse disrupts transitions into early adulthood

Thu, 2014-07-17 16:04
Adolescent alcohol abuse is known to be associated with adverse outcomes in early adulthood. It is unclear how much of this association is due to the influence of differences in familial background and shared genetics. New findings implicate a significant causal relationship between elevated drinking problems at age 18.5 and more adverse life outcomes at age 25 that cannot be fully explained by shared genetic and environmental liabilities.

Investing in sexual, reproductive health of 10 to 14 year olds yields lifetime benefits

Thu, 2014-07-17 07:51
Globally there are over half a billion 10 to 14 year olds. Researchers report these years provide a unique narrow window of opportunity to facilitate transition into healthy teenage and adulthood and lay out ways to invest in their future sexual and reproductive health. "Ten is not too young to help girls and boys understand their bodies and the changes that are occurring. Ten is not too young to begin to move them from ignorance to knowledge," said the senior author of the paper.
