Insomnia during adolescence may predispose diabetes in boys

Insomnia during adolescence may predispose diabetes in boys

Sleep time that a teenage boy has per night may influence his risk of developing insulin resistance and other health problems, according to a study presented at the annual meeting of the American Association for According to the study, boys who had a greater decline in the slow-wave sleep phase (SWS) as adolescents have a significantly higher chance of developing insulin resistance than those who maintained the amount of this sleep period as they grew. These boys were also more likely to develop type 2 diabetes, increased visceral fat, and attention deficit problems. These results were not observed in girls.

The slow wave phase (SWS) is an important stage of sleep that involves memory consolidation and recovery after a period of sleep deprivation. According to the authors, one night after sleep deprivation, the SWS phase will be significantly larger to compensate for the previous loss. They also said that we went out of this phase of sleep more quickly during adolescence, so due to the restorative role of this phase, they were not surprised to find that the metabolic and cognitive processes were affected during this period.

How the study was performed

Data collected from the Pennsylvania State University hospital were analyzed in order to understand the effects of loss or decrease of SWS during childhood and adolescence. There were 700 children of the local population, aged between five and 12 years old. Eight years later, 421 participants were also examined during adolescence, 53.9% of them were male.

Participants spent the night at the site prepared for analysis both early in the study and the second phase, and had their monitored for nine hours. In the consultations the participants' body fat rate and insulin resistance levels were verified, as well as neurocognitive functioning tests.

They found that in boys, greater deprivation of this type of sleep during childhood and adolescence was associated a significant increase in insulin resistance and a slight increase in abdominal fat and attention problems. However, this relationship was not found in girls of the same age.

The researchers further stated that the total amount of sleep of the participants did not decrease significantly with age, suggesting that the observed effects were due to a decrease in the sleep period. deeper sleep.

Further studies are needed to replicate these findings, especially in groups of other age groups. They recommend that people maintain a sleep routine in order to minimize the losses that happen naturally as they get older.


Gingival disease related to periodontal bone loss in women

Gingival disease related to periodontal bone loss in women

Women infected with strains of bacteria known to cause periodontal disease had a higher predisposition for more severe bone loss than women where these pathogens were not identified, according to researchers in a recent edition of the Journal of Periodontology. Epidemiologists at the State University of New York in the city of Buffalo conducted a cross-sectional study on oral health and osteoporosis in 1,256 postmenopausal women selected in the Observational Initiative Women's Health in the region.

Echocardiogram: examination makes a diagnosis of heart disease

Echocardiogram: examination makes a diagnosis of heart disease

An echocardiogram is an ultrasound scan that looks at how your heart works. The results are more detailed than those obtained on an x-ray, in addition to not exposing the patient to radiation. The device captures the sound waves that are emitted by all parts of the heart. These echoes are imaged and displayed on a monitor, allowing the physician to analyze all the characteristics of the patient's heart.
