Frisdranken verhogen de kans op astma en COPD*
Uit een Australische studie onder bijna 17.000 personen blijkt dat het regelmatig drinken van frisdranken de kans op astma en vooral COPD flink doet verhogen. Zij die dagelijks een halve liter of meer frisdranken dronken hadden bijna 30% meer kans op astma en bijna 80% meer kans op COPD dan zij die geen frisdrank dronken. Van de deelnemers, allen ouder dan 16 jaar, bleek ruim 11% meer dan een halve liter frisdrank per dag te drinken.

Soft drink consumption has been linked to a range of chronic diseases but no previous study was focused on the association with asthma/COPD. Among 16 907 participants aged 16 years and older living in South Australia, a positive association was identified between consumption of soft drinks and the risk of asthma/COPD.
ABSTRACT
Background and objective: The aim of this study was to examine the association between soft drink consumption and self-reported doctor-diagnosed asthma and COPD among adults living in South Australia.
Methods: Data were collected using a risk factor surveillance system. Each month a representative random sample of South Australians were selected from the electronic White Pages and interviews were conducted using computer-assisted telephone interviewing (CATI).
Results: Among 16 907 participants aged 16 years and older, 11.4% reported daily soft drink consumption of more than half a litre. High levels of soft drink consumption were positively associated with asthma and COPD. Overall, 13.3% of participants with asthma and 15.6% of those with COPD reported consuming more than half a litre of soft drink per day. By multivariate analysis, after adjusting for socio-demographic and lifestyle factors, the odds ratio (OR) for asthma was 1.26 (95% confidence interval (CI): 1.01–1.58) and the OR for COPD was 1.79 (95% CI: 1.32–2.43), comparing those who consumed more than half a litre of soft drink per day with those who did not consume soft drinks.
Conclusions: There was a positive association between consumption of soft drinks and asthma/COPD among adults living in South Australia. (Februari 2012)
