Are you at risk of bloodstream infections?

Serious bloodstream infections are common among smokers who are obese and inactive. The bloodstream infection is known as sepsis. People who develop sepsis are at risk of death from the infection.

Smoking combined with obesity and sedentary lifestyle can lead to blood poisoning. People with those three factors are at higher risk of sepsis than non-smoking, normal-weight and active people.

Body mass index is the estimate of body fat based on height and weight measurements. A BMI below 25 is considered normal weight, and anything over 30 is considered obese.
People with a BMI between 30 and 35 have increased risk of Sepsis.

Smoking increases the risk by 50 percent when compared with people who never smoked. And being completely inactive was tied to a nearly doubled sepsis risk, when compared with those who exercised strenuously for at least an hour a week.

Obese people may die from sepsis. People with a BMI of 40 or more have increased risk of dying from the infection. Regular exercise and avoiding smoking can reduce the risk of blood stream infections.

Circadian timing of food and body mass index

Researchers examined the relationships between body fat, body mass index and the timing of food consumption, to time of day and to the body's circadian clock. They discovered that the timing of food intake relative to melatonin onset, a marker of a person's biological night, is associated with higher Body Mass Index BMI, and not associated with the time of day, amount or composition of food intake.

The time of calories consumption, relative to personal biological timing may be more important for health than the actual time of the day. Researchers analyzed data collected from different participants to monitor daily meal intake.

Investigation to assess the timing of their melatonin onset, marking onset of sleep, and their body composition.
Researchers found that individuals with high body fat percentages consumed most of their calories shortly before going to sleep when melatonin levels were high, compared to individuals with lower percentages of body fat.

Researchers found that they were unable to detect a relationship between the clock hour of food intake, caloric amount, meal composition, exercise level, or sleep duration, and either of these body composition measures.

Researchers concluded that these results provide evidence that the consumption of food during the circadian night, independent of more traditional risk factors such as amount or content of food intake and activity level, plays an important role in body composition.
