Among approximately 26,000 women, receipt of the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine during pregnancy was not associated with increased risk of preterm delivery or small-for-gestational-age birth or with hypertensive disorders of pregnancy, although a small increased risk of being diagnosed with chorioamnionitis (an inflammation of the membranes that surround the fetus) was observed, according to a study.
By following dozens of younger and older adolescents for more than two years, researchers in a new study were able to determine that the children fell asleep later and their circadian rhythms shifted later as they grew older. But early school start times interfere with their tendency to sleep later, reducing their total sleep. The study bolsters new recommendations for later school start times.
Teenagers are much more likely to take up smoking if they live in neighborhoods with a large number of shops that sell tobacco products, a study suggests. Adolescents with the most tobacco outlets in their neighborhood are almost 50% more likely to smoke than those with no outlets nearby, researchers say.
Symptoms of mental illness in children and adolescents do not appear to be increasing, according to a large study of Canadian youth. "Popular media tends to perpetuate the idea that the prevalence of mental disorders is increasing," write the authors of a new report. "However, research supporting this position has been inconsistent."
A new study provides valuable evidence that New Jersey’s Graduated Driver Licensing (GDL) decal provision is associated with a sustained two-year decline in crash rates among intermediate or probationary teen drivers.
Drug tests on 517 mothers in English inner city hospitals found that nearly 15 percent had taken recreational drugs during pregnancy and that mothers of babies with birth defects of the brain were significantly more likely to have taken drugs than mothers with normal babies. The study found no significant links between recreational drug use and any other type of birth defect.
Kidney failure later in life can be predicted based on measurements taken in adolescence, according to a study. "It is never too early to tackle issues like unhealthy weight gain and hypertension as it may be much harder to begin a healthy lifestyle in later adulthood. How you live as a teenager has consequences for your health in middle age,” researchers state.
Most Americans who spend part of the year on daylight saving time look forward to the extra hour of sleep when it’s time to “fall back” to standard time. We are a nation of sleep-deprived people, and experts say all ages suffer in various, unhealthy ways.
Women who developed gestational diabetes and were overweight before pregnancy were at a higher risk of having daughters who were obese later in childhood, according to new research. Based on long-term research that included a multi-ethnic cohort of 421 girls and their mothers, the study is among the first to directly link maternal hyperglycemia (high blood glucose) to offspring being overweight later.
Those who self-harm as teenagers are more at risk of developing mental health and substance misuse problems as adults, new research from the biggest study of its kind in the UK has revealed.
Use of electronic cigarettes among students in Poland has increased dramatically, rising more than threefold in just the last three years, research finds. Electronic cigarettes are battery-operated products that heat a liquid solution that vaporizes nicotine and other additives, which are then inhaled by the user.
Subjective screening questions do not reliably identify teenagers who are at risk for hearing loss, according to researchers. Their study results suggest that objective hearing tests should be refined for this age group to replace screening questions.
Children who show poor decision-making skills at age 10 or 11 may be more likely to experience interpersonal and behavioral difficulties that have the potential to lead to high-risk health behavior in their teen years, according to a new study.
The effects of smoking during pregnancy, and its impact on the stress response in newborn babies, has been the focus of recent study. The research indicates that newborns of mothers who smoke cigarettes during pregnancy show lower levels of stress hormones, lowered stress response, and alterations in DNA for a gene that regulates passage of stress hormones from mother to fetus.
Although progress has been made in recent years, the matter of youth suicide in Quebec still needs to be more effectively addressed. In fact, a new study shows that more lives could be saved through early detection and increased public awareness and information sharing among professionals.
Young baseball pitchers who throw more than 100 pitches per week are at risk for a newly identified overuse injury that can impede normal shoulder development and lead to additional problems, including rotator cuff tears, according to a new study.
Intensive parenting and health education provided in homes of pregnant American Indian teens reduced the mothers’ illegal drug use, depression and behavior problems, and set their young children on track to meet behavioral and emotional milestones they may have otherwise missed.
Adolescence is often a turbulent time, and it is marked by substantially increased rates of depressive symptoms, especially among girls. New research indicates that this gender difference may be the result of girls' greater exposure to stressful interpersonal events, making them more likely to ruminate, and contributing to their risk of depression.
Parents are being warned by scientists that difficult eaters could have underlying psychological issues, as they have found that restrictive behaviors can appear before puberty.
Sugar consumption affected memory and was linked to brain inflammation in juvenile rats, researchers report. "The brain is especially vulnerable to dietary influences during critical periods of development, like adolescence," remarked a corresponding author of the study. "Consuming a diet high in added sugars not only can lead to weight gain and metabolic disturbances, but can also negatively impact our neural functioning and cognitive ability."
