Stressed parents make for obese kids Researchers have linked parental stress to weight gain in children. The study found that children whose parents have high levels of stress have a BMI about 2 per cent higher than those parents with low stress levels. Kids with higher parental stress also gained weight at a 7 per cent higher rate during the study period than other children. Those figures though low, said lead author Dr Ketan Shankardass, are significant because these are happening in children, whose bodies and eating and exercise habits are still developing. Plus, if that weight gain continues it could lead to serious obesity and health issues. Dr Shankardass, a social epidemiologist, studied data from the Children's Health Study, a large and comprehensive investigation into the long-term effects of air pollution on the respiratory health of children. The childrens' BMI was calculated each year. Their parents were given a questionnaire to measure their perceived psychological stress that asked how often in a month they were able or unable to control important things and whether things were going their way or their difficulties were piling up that they could not overcome. Dr Shankardass noted that more than half the students followed in the California study were Hispanic, and that the effects of stress on their BMI was greater than children of other ethnic backgrounds. The research has been published in the journal Pediatric Obesity. Antacids may up vitamin deficiency Popular drugs that are used to control stomach acid may increase the risk of a serious vitamin deficiency, says a new study. Researchers found people who were diagnosed with vitamin B12 deficiency were more likely to be taking proton-pump inhibitors and histamine 2 receptor antagonists, compared to those not diagnosed with the condition.

Diabetes linked to higher liver cancer risk A new study has found that diabetes was associated with an increased risk for developing a type of liver cancer called hepatocellular carcinoma. "People with diabetes have a two to threefold higher risk for hepatocellular carcinoma compared with those without diabetes," V. Wendy Setiawan, Ph.D., assistant professor in the Department of Preventive Medicine at Keck School of Medicine of the University of Southern California, said. "We also found that the interethnic differences in the prevalence of diabetes were consistent with the pattern of hepatocellular carcinoma incidence observed across ethnicities: Ethnic groups with a high prevalence of diabetes also have high hepatocellular carcinoma rates, and those with a lower prevalence of diabetes have lower hepatocellular carcinoma rates," Setiawan said. Setiawan and colleagues examined if the association between diabetes and hepatocellular carcinoma differed by race or ethnic group. They analysed data from more than 150,000 people enrolled in the Multiethnic Cohort Study between 1993 and 1996. Compared with non-Hispanic whites, Latinos had 2.77 times the risk for being diagnosed with hepatocellular carcinoma, the highest risk identified. Native Hawaiians had 2.48 times the risk; African-Americans, 2.16; and Japanese-Americans, 2.07. The prevalence of diabetes was consistent with that of hepatocellular carcinoma. Sixteen percent of Hawaiians, 15 percent of Latinos and African-Americans, 10 percent of Japanese-Americans, and 6 percent of non-Hispanic whites had diabetes. The study was presented at the Sixth AACR Conference. Yelling harms teens' mental health Threatening or screaming at teenagers may put them at higher risk for depression and disruptive behaviors such as rule-breaking, a new study suggests. "The take-home point is that the verbal behaviours matter," Annette Mahoney, who worked on the study, said. She's a professor of psychology at Bowling Green State University in Ohio. — Agencies

Scientists have linked
inadequate sleep to mood disturbances and lower quality of life in
extremely obese people, said a study. "There was a clear
association between the sleep problems such as short sleep duration,
and the psychological disorders, and with quality of life," said
G. Neil Thomas, lead supervisor, study methodology lead, reader in
epidemiology at the Department of Public Health, Epidemiology and
Biostatistics at the University of Birmingham in Britain. The study
results appear in the December issue of the journal Sleep,
reports the Science Daily. "This study emphasises the need
for physicians to conduct routine screenings for sleep problems among
people with severe obesity," said M Safwan Badr, president of the
American Academy of Sleep Medicine. "Improving sleep quality, and
quantity will provide a physical, mental, and emotional boost for
people, who are making the difficult lifestyle changes involved in
managing obesity."
