Maternal fish consumption during pregnancy and smoking behavioural patterns

Area of Science:

• Neuroscience
• Nutritional Science
• Public Health

Background:

• n-3 Highly Unsaturated Fatty Acids (HUFA) are vital for neuronal membrane function and associated with various biological processes.
• Deficiencies in n-3 HUFA have been linked to increased risks for addictive disorders.
• Maternal smoking during pregnancy poses significant health risks to both mother and child.

Purpose of the Study:

• To investigate the association between fish consumption and maternal smoking during pregnancy.
• To examine if higher intake of n-3 HUFA-rich foods correlates with lower smoking rates in pregnant women.

Main Methods:

• Utilized data from 9640 mothers in the Avon Longitudinal Study of Parents and Children.
• Employed univariable and multivariable regression models to analyze dietary intake of fish/shellfish and smoking habits.
• Assessed smoking cessation and daily cigarette consumption in relation to fish intake at 32 weeks gestation.

Main Results:

• Consistent protective associations were observed between fish intake and smoking before and during pregnancy (P<0.001).
• Mothers consuming some (<340 g/week) or high (340 g+/week) amounts of fish showed significantly lower odds of smoking.
• Adjusted odds ratios were 0.87 (95% CI 0.77, 0.97) for some fish intake and 0.73 (95% CI 0.61, 0.86) for high fish intake.

Conclusions:

• Higher fish consumption is associated with a reduced likelihood of smoking during pregnancy.
• These findings suggest that increasing fish or n-3 HUFA intake could be a potential intervention strategy to reduce maternal smoking.
• Further evaluation in randomized clinical trials is warranted to confirm the efficacy of fish/n-3 HUFA as a smoking cessation aid.
