Abstract: Telomeres are protective DNA sequences located at chromosome ends, essential to maintaining genomic stability. This narrative review examines how maternal lifestyle factors during pregnancy influence fetal telomere length (TL). Positive associations have been identified between offspring's TL and maternal consumption of nutrients such as vitamins C and D, folate, and magnesium. Additionally, adherence to a Mediterranean diet and regular physical activity during pregnancy are correlated with increased placental TL, supporting fetal genomic integrity. Conversely, maternal dietary patterns high in carbohydrates, fats, or alcohol, as well as exposure to triclosan and sleep-disordered breathing, negatively correlate with offspring's TL. Maternal infections may also shorten TL through heightened inflammation and oxidative stress. However, evidence regarding the impact of other lifestyle factors-including maternal stress, smoking, caffeine intake, polyunsaturated fatty acid consumption, obesity, and sleep quality-remains inconsistent. Given that shorter telomere length has been associated with cardiovascular, pulmonary, and neurodegenerative diseases, as well as certain types of cancer, these findings highlight the vital importance of maternal health during pregnancy in order to prevent potential adverse effects on the fetus. Further studies are required to elucidate the precise timing, intensity, and interplay of these influences, enabling targeted prenatal interventions to enhance offspring health outcomes.
