Passive smoking is associated with lung disease in children
Secondhand smoke can affect the behavior and learning of children, to favor the appearance of ear problems and still to cause the little ones to miss more in the school. But the problems stemming from living with an adult addicted to smoking do not stop there. A new study links living with someone who cultivates this habit to develop lung disease years later.
The analysis, led by a team from Haukeland University Hospital in Norway, was attended by more than 700 adults, of which 433 were diagnosed with chronic obstructive pulmonary disease and 325 without the disease. The researchers then investigated the risk factors for developing the condition, which may be characterized by emphysema and chronic bronchitis.
They found that women exposed to secondhand smoke as children had a 1.9-fold increased risk of developing diseases than those who had not had the same experience. While men exposed to the dangerous substances of cigarette smoke as children had a 1.7-fold higher risk of having lung problems than the others.
The study, published in the journal Respiralogy, aims to emphasize the dangers of smoking. The authors also point out that exposure to passive smoking in childhood seems to be more aggressive than the same exposure in adulthood.
Passive smoking is primarily responsible for chronic sinusitis
Other people's cigarette smoke is also one of the leading culprits for sinusitis cases, according to a study from the University of Brock in Canada. The disease is marked by inflammation in the nasal cavity and sinuses, resulting in itching, coryza, nasal congestion and headaches. According to the researchers, the problem affects one in six American adults, causing great discomfort. From the study, researchers say that secondhand smoke may be behind 40 percent of chronic sinusitis cases in the United States.
To reach these results, the survey, published in the April issue of the journal Archives of Otolaryngology , evaluated 306 non-smokers who developed the condition of sinusitis and 306 healthy non-smokers. Through the follow-up of these volunteers, the researchers found that participants who are very exposed to other people's cigarette smoke - especially in the workplace and on social occasions such as parties and gatherings - have tripled the odds of developing chronic disease. Within the first group, analyzes showed that exposure to secondhand smoke at home was 13%, 19% at work and 51% at private social gatherings. Compared with the healthy group, these numbers were much lower: 9% at home, 7% at work and 28% at social gatherings.
Study coordinator Martin Tammemagi said in a US press release that was surprised to discover that more than half the population (53% of people) have some exposure to secondhand smoke. The doctor underscored the need for more government investment to reduce this number.
Solitude is a feeling that can cause emptiness and isolation, negatively affecting a person's life. Keith Davidson is a retired judge of 94 years who lives alone in Minnesota, the United States. In 2016, after the death of his wife, the old man began to feel very lonely, so he decided to create a plan to change that.
Of the Society of Endocrinology points out that women diagnosed with gestational diabetes have a greater risk of developing type 2 diabetes in the future than other pregnant women. According to experts, the relationship may stem not only from bad habits, but also from genetic variations. The analysis was led by a researcher from Seoul National University Hospital.
