Parents, take note. Researchers have found that heavier babies are more likely to suffer childhood food allergies or eczema.

For the study, published in the Journal of Allergy and Clinical Immunology, the research team carried out a systematic review assessing past studies in humans.

After screening more than 15,000 studies, they identified 42 that included data on more than two million allergy sufferers.

“We analysed the associations between birth weight, corrected for gestational age, and the incidence of allergic diseases in children and adults,” said Kathy Gatford from the University of Adelaide in Australia.

“For each kilogram increase in birth weight there was a 44 per cent increase in the risk that a child had food allergies or a 17 per cent increase in the risk that they had eczema,” Gatford said.

According to the researchers, they analysed studies that included over 2.1 million people affected by allergic dermatitis, commonly known as eczema, nearly 70,000 people affected by food allergies and over 100,000 people with allergic rhinitis or hay fever.

Most of the studies were in children from developed countries and most were European.

“Allergic diseases including eczema, hay fever, food allergies, anaphylaxis and asthma are estimated to affect 30-40 per cent of the world’s population,” Gatford said..

“It is increasingly clear that genetics alone do not explain risks of developing allergies, and that environmental exposures before and around birth can programme individuals to increased or decreased risk of allergies,” Gatford added.

Saliva can Help Detect Surplus Body Fat in Teenagers: Study

Saliva helps in predicting various diseases in teenagers

In addition to keeping the mouth moist and protecting us against germs, saliva can also be used for early detection of the risk of developing diseases associated with surplus body fat, a new study suggests.

For the findings, published in the journal Nutrition Research, the researchers in Brazil performed a study in which they used the level of uric acid in saliva to predict body fat percentages in teenagers and identify those with surplus fat even if they had no symptoms of chronic obesity-related disease.

The goal of the study was to identify reliable biomarkers in saliva that correlated with those found in the blood as a contribution to the development of quick tests to monitor health, especially in children.

The research showed the level of salivary uric acid to be a good predictor of body fat percentage even in adolescents considered.

“The idea is to enable saliva to be more widely used as an alternative biological sample for clinical analysis. The advantage of saliva is that it can be collected several times noninvasively and painlessly, like urine,” said study researcher Paula Midori Castelo from Federal University of Sao Paulo (UNIFESP) in Brazil.

In the study, the researchers collected saliva samples from 129 girls and 119 boys. In addition to uric acid, they measured the levels of several other substances, including cholesterol and vitamin D.

The participants were aged 14-17 and were students at public schools in Piracicaba, São Paulo State. They first answered a questionnaire on their medical and dental history.

They also underwent an oral examination to exclude participants with cavities and periodontal disease (gum inflammation).

“Cavities and periodontal disease are known to influence salivary parameters such as pH (acidity), electrolytic composition and biochemistry. Both relate to the secretion of substances that can change the composition of saliva,” Castelo explained.

Using linear regression (a statistical technique that analyzes the relationships between variables), the researchers were also able to predict body fat percentage based on the level of salivary uric acid.

“The level of this compound in saliva proved to be a reliable indicator of body fat accumulation, even in adolescents who were not being treated for chronic disease. It could be the basis for an accurate noninvasive method of monitoring dietary health and achieving early detection of changes in nutritional state,” Castelo said. (IANS)
