Lifestyle changes in mothers with obesity could mitigate heart risks in offspring
Researchers at King’s College London have discovered that lifestyle modifications could potentially reduce the risk of children developing certain cardiovascular diseases, which are believed to stem from maternal obesity and related foetal heart abnormalities.
Globally, obesity rates among pregnant women are on the rise, with more than half of the women attending antenatal clinics in England and Wales either having overweight (28.5%) or obesity (22.7%). Studies have increasingly shown that obesity during pregnancy can precipitate cardiovascular complications and disrupt normal cardiac development in the offspring.
The findings were detailed in a recent publication in the International Journal of Obesity, led by Dr Samuel Burden. The research team conducted a systematic review of existing studies to explore whether interventions targeting obesity in pregnant women—through diet, exercise, and other physical activities—can foster cardiac health in their children.
The selection criteria for the studies included randomised trials focusing on lifestyle changes among pregnant women diagnosed with obesity. The evidence reviewed indicated that such interventions could avert atypical cardiac development in children, highlighting several benefits commonly associated with improved heart health, such as decreased thickening of the heart walls, maintaining normal heart weight, and reducing the likelihood of increased heart rates.
Dr Samuel Burden commented, “We and others have demonstrated that maternal obesity correlates with signs of poor heart development in children. Our review of existing literature on dietary and exercise interventions in women with obesity, either before or during pregnancy, revealed that these measures indeed offer a protective shield against the extent of this unhealthy heart development in children. Should these results hold into adulthood, these interventions could shield against the detrimental cardiovascular conditions seen in adult children of mothers with obesity, thus guiding public health strategies to enhance cardiovascular health for future generations.”
Although the data supports the premise that lifestyle adjustments in pregnant women with obesity may safeguard infant cardiovascular health, further comprehensive studies are necessary. These should involve larger cohorts and extend into later childhood to affirm the findings and assess if the benefits continue into adulthood.
Should future research corroborate these findings, the implications could be significant, potentially shaping public health initiatives aimed at improving heart health across generations.
