Reported link between diet drinks and dementia and stroke is weak
Conclusion The researchers used data from a large ongoing cohort study to look for links between consumption of sugary and artificially sweetened drinks and risk of stroke or dementia. This cohort study benefits from the large overall sample size, long period of data collection, careful and valid diagnostic assessments, and adjustments for a number of confounders. However, care must be taken when interpreting these results – particularly if latching on to the maximal tripled risk figures reported in the media. There are several points to consider: Small numbers The new number of strokes and dementia in this study was sma...

People with gout have lower risk of Alzheimer’s disease
Conclusion This population-based study has found that people with gout had a 24% reduced risk of developing Alzheimer’s disease. It was a well-designed study, in that there were large numbers of people in each group and multiple potential confounding factors were taken into account. The validation of the study was also valuable in showing the expected lack of a link between osteoarthritis and Alzheimer’s disease. However, there are some limitations with this type of study, with a major one being that it cannot prove cause and effect. While some potential confounding factors were accounted for in the statistical analysi...

Sugary drinks linked to increased fat levels around vital organs
Conclusion This US cohort study found drinking sugar-sweetened beverages on a daily basis is associated with the highest increase in fat accumulation around the abdominal organs, compared with people who do not consume them. But there was an average increase in the amount of this fat in all people who took part in the study, although this was lowest in people who never consumed sugar-sweetened beverages. The study was prospective, which limits some sources of bias, but it has some limitations. For example, the food frequency questionnaire was only conducted once, at baseline. The results are therefore reliant on the p...

Snoring link to Alzheimer ’s disease unproven
Conclusion This relatively large cross-sectional analysis has found a link between certain measures of breathing problems during sleep and poorer cognitive function in middle-aged to older adults. The strengths of this study include its size and use of a prospective sleep study to assess whether people had sleep apnoea or other problems with breathing during sleep. The use of standard cognitive tests is also a strength. However, the study does have its limitations: The study did have mixed findings – while certain measures of problems with breathing during sleep (e.g. oxygen levels) were associated with cognitive outco...
