Overweight children suffer from more apnea and cognitive problems

Overweight children suffer from more apnea and cognitive problems

SDS levels were measured according to the Obstructive apnea, defined as the number of apneas and hypopnoea (decreases in oxygenation during sleep) per hour of total sleep time. Body mass indexes were defined as body mass index (BMI).

Because they were three factors - weight, sleep and cognitive processing -, the researchers used each one of them as mediators to better understand the results. Using the DRS as a mediator, the more DRS problems, the worse the results in cognitive tests and the greater the BMI.

The greater the body mass, the greater the chances of sleep disorders and cognitive problems. Already using cognition as a mediator, the low ability to complete more complex mental tasks showed a connection with higher body mass indexes and problems with DRS.

For the researchers, all three factors are closely related, although the relationship is not yet known . The results were published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Sleep Apnea Increases Chances of Cognitive Impairment in Women

The relationship between sleep apnea and cognitive problems has already been studied. A study, published in the Journal of the American Medical Association, found that sleep apnea can cause mild cognitive impairment and even dementia in women. The analysis was led by scientists at the University of California, USA.

The study was supported by 298 women considered to be mentally and physically fit and with an average age of 82 years. Of these, 105 were diagnosed with sleep disorders, with 15 or more breaths while they slept.

The results of follow-up examinations five years after the start of the study showed that approximately 45% of those who had sleep apnea had developed mild cognitive impairment or dementia. Among those who had normal sleep, about 30% developed one of the diseases. However, when characteristics linked to ethnicity and which indicated poor quality of life, such as smoking, the probability of developing such diseases increased to 85%.

Sleep apnea is characterized by respiratory arrest during sleep and can be become a chronic problem, leading to death. People overweight or over the age of 30 are the most affected.


Beautiful couples have more daughters, suggests study

Beautiful couples have more daughters, suggests study

The evolutionary psychologist Satoshi Kanazawa of the London School of Economics conducted a survey in which he concluded that "beautiful parents tend to have more daughters." For this study, which will be published in a forthcoming issue of the journal Reproductive Science, Kanazawa tracked 17,000 British babies born in the 1950s.

Prenatal Genetic Counseling Shows Possible Risks of Gestation

Prenatal Genetic Counseling Shows Possible Risks of Gestation

Prenatal genetic counseling is a consultation with a geneticist who must precede any genetic test. It consists basically of a conversation with the geneticist doctor with the couple during the pregnancy. There are currently tests that the couple can perform even before the first gestation, which aims to prevent the occurrence of malformations or mental deficiency already before the first gestation.
