According to an international study, children who get more exercise also tend to do better in school.

The findings come as schools in the United States, in general, cut physical activity time in favor of more academic test preparation.

Amika Singh, who worked on the study, said, “Maybe it’s an activity break, stand up every half an hour in class and do something,” said Singh, from VU University Medical Center in Amsterdam.

“It might mean going to school by bike … Any kind of physical activity you can think of. It doesn’t mean only the physical education standard class.”

The findings were published in the Archives of Pediatrics & Adolescent Medicine.

According to researchers from the United States, some adolescent girls who get the HPV vaccine for preventing cervical cancer wrongly think they no longer need to practice safe sex.

The study, which was published in the Archives of Pediatric & Adolescent Medicine, demonstrated the need for better education about the vaccines and their limitations.

Merck’s Gardasil and GlaxoSmithKline’s Cervarix vaccines protect against strains of the humanpapilloma virus or HPV but do not prevent other forms of sexually transmitted diseases such as syphilis, gonorrhea, or human immunodeficiency virus or HIV that causes AIDS.

“Clinicians discussing HPV vaccination with girls and their mothers may need to emphasize the limitations of the vaccine and to specifically address that the vaccine does not prevent other sexually transmitted infections,” the team wrote.

On Friday, conflicting advice was issued by France and Britain to tens of thousands of women with breast implants made of cheap industrial silicone that some fear pose health risks.

Around 30,000 French women were urged by the government to seek eek removal of the implants, made by now-defunct French company Poly Implant Prothese (PIP) that may rupture and cause inflammation and irritation.

But in Britain, where an estimated 30,000 to 40,000 women are affected, Chief Medical Officer Dame Sally Davies said: “Women with PIP implants should not be unduly worried. We have no evidence of a link to cancer or an increased risk of rupture. If women are concerned they should speak to their surgeon.” Removing implants “carries risks in itself”, she said. “I do think that every woman who has these implants should go and get checked … It’s better to have them replaced than to worry about them rupturing,” said British woman Pat Demetriou, who had faulty PIP implants removed in 2010.

A new U.S. study has revealed that toddlers who have poor relationships with their moms are more likely to pack on extra pounds as they grow up.

The involved researchers found more than a quarter of those who scored lowest on mother-child relationship tests as toddlers went on to become obese at age 15.

“There is an overlap in the brain between the areas that govern stress and energy balance,” said Sarah E. Anderson, who worked on the new study and of the Ohio State University College of Public Health in Columbus. “This stress response could be related to obesity through appetite regulation.”
