WASHINGTON — Larger waistlines or higher levels of belly fat are associated with higher risk of vitamin D deficiency, according to a report presented in Barcelona at the European Society of Endocrinology annual meeting, ECE 2018.
The study reports that vitamin D levels are lower in individuals with higher levels of belly fat, and suggests that individuals, particularly the overweight with larger waistlines should have their vitamin D levels checked, to avoid any potentially health damaging effects.
Rachida Rafiq and colleagues from the VU University Medical Center and Leiden University Medical Center in the Netherlands, examined how the amount of total body fat and abdominal fat measured in participants of the Netherlands Epidemiology of Obesity study related to their vitamin D levels.
After adjusting for a number of possible influencing factors, including chronic disease, alcohol intake and levels of physical activity, the reasearhers found that the amounts of both total and abdominal fat were associated with lower vitamin D levels in women, although abdominal fat had a greater impact.
In men abdominal fat and liver fat, was associated with lower vitamin D levels. But in all cases the greater the amount of belly fat, the lower the levels of detected vitamin D.
Rachida Rafiq said, “Although we did not measure vitamin D deficiency in our study, the strong relationship between increasing amounts of abdominal fat and lower levels of vitamin D suggests that individuals with larger waistlines are at a greater risk of developing deficiency, and should consider having their vitamin D levels checked.”
The researchers now plan to investigate what may underlie this strong association between vitamin D levels and obesity – whether a lack of vitamin D is predisposing individuals to store fat, or whether increased fat levels are decreasing vitamin D levels is not yet clear.

Sudden cardiac arrests are more likely to happen on any day at any time : Study
A new study has showed that sudden cardiac arrests are more likely to happen on any day at any time, challenging previous claims that weekday mornings — especially Mondays — were the danger zones.
Previously heart experts have long believed that weekday mornings were the danger zones for unexpected deaths from sudden cardiac arrests.
“While there are likely several reasons to explain why more cardiac arrests happen outside of previously identified peak times, stress is likely a major factor,” said Sumeet Chugh, a Professor of medicine from the Smidt Heart Institute in the US.
“We now live in a fast-paced, ‘always on’ era that causes increased psycho-social stress and possibly an increase in the likelihood of sudden cardiac arrest,” Chugh added.
Almost 17 million cardiac deaths occur annually worldwide while the survival rate from sudden cardiac arrest is less than one per cent.
For the study, published in the journal Heart Rhythm, Chugh’s team analysed data on 1,535 from the community-based Oregon Sudden Unexpected Death Study between 2004 to 2014, among which only 13.9 per cent died in the early morning hours, the findings revealed.
All reported cases were based on emergency medical service reports containing detailed information regarding the cause of the cardiac arrest.
“Because sudden cardiac arrest is usually fatal, we have to prevent it before it strikes,” Chugh said. “Our next steps are to conclusively determine the underlying reasons behind this shift, then identify public health implications as a result,” he added.
Apart from stress, other contributing factors may be a shift in how high-risk patients are being treated, as well as inadequacies in how past studies have measured time of death caused by sudden cardiac arrest.Follow @gorkhapost
