Consumption of beverages has been linked to weight gain, type 2 diabetes, early menstruation, poor semen quality and infertility. A new study led by Boston University School of Public Health (BUSPH) researchers has found that the intake of one or more sugar-sweetened beverages per day is associated with a decreased chance of getting pregnant.
There are links between intake of sugar-sweetened beverages and low fertility, which were consistent after controlling for many other factors, including obesity, caffeine intake, alcohol, smoking, and overall diet quality. Couples planning a pregnancy might consider limiting their consumption of these beverages, especially because they are also related to other adverse health effects.
Risk factors for infertility including diet, could help couples conceive more quickly and reduce the psychological stress The researchers surveyed 3,828 women aged 21 to 45 living in the United States or Canada and 1,045 of their male partners.
Participants completed a comprehensive baseline survey on medical history, lifestyle factors, and diet, including their intake of sugar-sweetened beverages. Female participants then completed a follow-up questionnaire every two months for up to 12 months or until pregnancy occurred.
Both female and male intake of sugar-sweetened beverages was associated with 20 percent reduced fecundability, the average monthly probability of conception. Females who consumed at least one soda per day had 25 percent lower fecundability; male consumption was associated with 33 percent lower fecundability. Intake of energy drinks was related to larger reductions in fertility, although the results were based on small numbers of consumers.
