The World Health Organization (WHO) says obese and overweight people in Europe have reached "epidemic ratios" and obesity is responsible for more than 1 million deaths each year.
In a report issued on Tuesday, the United Nations European Office said that "the prevalence of obesity among adults is higher across the continent than in any other region of the world, except in the Americas", and that overweight is "among the leading causes of death in the region."
The authors of the report expressed concern at the continued rise in the prevalence of overweight and obesity in the World Health Organization's European region and noted that "no Member State is on track to reach the goal of halting the rise in obesity by 2025".
Among the countries reported in the report for the European region, the World Health Organization (WHO) said that Turkey, Malta, Israel and the United Kingdom had the highest obesity rates.
During the COVID-19 pandemic, we witnessed the real impact of the obesity epidemic, "WHO Europe Director Hans Klug wrote in the report, noting that obese people were" more likely to suffer severe outcomes from the spectrum of COVID-19 disease, including ICU admission and death. "
Study reveals the impact of obesity on the number of sperm in men!
A study found that obese men in their 60s had fewer sperm than slim individuals in the same age group.
Scientists led by the University of Utah considered 44000 testicular cells involved in sperm production from eight men between the ages of 60 and 72, and four men in their early 20s.
Older men with a healthy weight showed a "poor" reduction in their ability to form sperm compared to younger men. But those who are obese have shown a "very limited" ability to continue producing male sex cells.
Scientists have not indicated why the number of sperm in older obese men is so low, although previous studies have suggested this may be due to low testosterone levels or high testicular temperature.
The Centers for Disease Control and Prevention estimates that about two in five Americans -- or 138 million people -- are obese.
Sperm numbers generally decline in age, peaking when a man turns 17 years old and staying high until the 1940s.
Studies in Europe, North America and Australia show that levels among men have generally declined since the 1970s.
It is not clear what caused this decline, but scientists have suggested that waist increases, poor diets and even exposure to pollution should be behind it.
In the study -- published today in the journal Developmental Cell -- scientists used autopsy to obtain testicular cells. They then examined RNA cells for age-related changes, to determine their quality in sperm manufacturing.
Of the participants over the age of 60, five had a body mass index (BMIs) of less than 27, placing them in the excess and healthy weight range. Three of them had a BMI above 30, placing them in the obesity category. They all had children, who showed fertility in their younger years.
In the younger men's group, aged 17 to 22, there were individuals with healthy and obese weight.
The results showed that these in the younger age group had "natural and complete" sperm production regardless of their BMI measurements.
But in older groups, she said this drops if someone has a higher body mass index.
Dr. Bradley Cairns, Chair of Oncology at the University of Utah who led the study, said: "Apparent dysregulation occurs when aging is associated with additional factors such as obesity. ageing may be granted a set of modest molecular changes that sensitize the testicle to further disorganization ".
Previous studies have linked weight gain to low testosterone level, suggesting that they may reduce sperm counts.
There are also suggestions that obese people have warmer testicles due to increased fat cells, which may hinder sperm production.
Sperm is produced at about 93 F (34 ° C), slightly below the human body temperature of 98.6 F (37 ° C).
Scientists said they were unable to determine whether changes in sperm production in older obese men were unique or due to accelerated aging.
Studies involving more individuals are needed to confirm the results.
