Insights
Breastfeeding is linked to lower blood pressure in infants. Formula feeding and mixed feeding were associated with higher blood pressure, BMI, and weight gain in infants.
Area of Science:
- Pediatrics
- Cardiology
- Nutrition Science
Background:
- Childhood blood pressure tracks into adulthood.
- Breastfeeding is recognized for its cardioprotective effects.
- Understanding infant feeding's impact on blood pressure is crucial.
Purpose of the Study:
- To evaluate the association between infant feeding types and blood pressure levels.
- To compare blood pressure in exclusively breastfed, mixed-fed, and formula-fed infants.
Main Methods:
- Comparative cross-sectional study in term infants.
- Blood pressure, heart rate, and respiratory rate measurements.
- ANOVA and multiple regression analysis for data comparison.
Main Results:
- Formula-fed infants showed higher weight and weight gain.
- Higher systolic, diastolic, and mean blood pressure in formula and mixed-fed groups.
- Current BMI, weight gain, and formula feeding associated with mean blood pressure.
Conclusions:
- Exclusively breastfed infants exhibit lower blood pressure.
- Breastfeeding is associated with reduced BMI and weight gain.
- Infant feeding practices significantly impact early cardiovascular health indicators.
Introduction:
Blood pressure levels in childhood influence these levels in adulthood, and breastfeeding has been considered such as a cardioprotective. We evaluated the association between blood pressure levels and feeding type in a group of infants.
Material And Methods:
We conducted a comparative cross-sectional study in term infants with appropriate weight at birth, to compare blood pressure levels in those children with exclusively breastfeeding, mixed-feeding and formula feeding. The comparison of groups was performed using ANOVA and multiple regression analysis was used to identify variables associated with mean arterial blood pressure levels. A p value < 0.05 was considered significant.
Results:
We included 20 men and 24 women per group. Infant Formula Feeding had higher current weight and weight gain compared with the other two groups (p < 0.05). Systolic, diastolic and mean blood pressure levels, as well as respiratory and heart rate were higher in the groups of exclusively formula feeding and mixed-feeding than in those with exclusively breastfeeding (p < 0.05). Multiple regression analysis identified that variables associated with mean blood pressure levels were current body mass index, weight gain and formula feeding.
Conclusions:
Infants in breastfeeding show lower blood pressure, BMI and weight gain.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

01:30Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...

Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
