Infantile overnutrition in the first year of life: a field study in Dudley, Worcestershire
Insights
Overnutrition is a significant issue in infants, with many exceeding recommended energy and protein intake levels. Early introduction of solids contributes to infantile obesity and overweight conditions.
Area of Science:
- Pediatric Nutrition
- Infant Growth and Development
- Public Health
Background:
- Infant feeding practices significantly influence growth and long-term health outcomes.
- Overnutrition and obesity in infancy are growing public health concerns.
- Established nutritional guidelines exist for infant feeding, but adherence and impact require ongoing study.
Purpose of the Study:
- To investigate infant feeding patterns and nutrient intake.
- To assess the relationship between feeding patterns and infant growth, specifically obesity.
- To compare nutrient intake against recommended levels for infants up to one year of age.
Main Methods:
- A survey was conducted on 300 normal infants up to one year of age in Dudley, Worcestershire.
- Feeding patterns, including the introduction of solid foods and nutrient intake (energy, protein, fat, carbohydrates), were recorded.
- Infant growth parameters were assessed, with a focus on identifying overweight and obese infants.
Main Results:
- Overnutrition was prevalent, with 16.7% of infants suffering from infantile obesity and 27.7% being overweight.
- Daily energy intake exceeded recommended levels, particularly in the first three months, coinciding with early introduction of solids.
- Protein intake was persistently high throughout the first year, exceeding recommended levels; fat and carbohydrate intake were also noted as high in early infancy.
Conclusions:
- Early introduction of solid foods and high nutrient intake contribute to infantile obesity and overweight conditions.
- There is a strong correlation between parental obesity and infant overweight/obesity, suggesting a potential preventative role for managing infant overfeeding.
- Findings highlight the need for greater awareness and adherence to infant feeding guidelines to mitigate risks of overnutrition and associated health issues.
Abstract:
A survey of feeding patterns and nutrient intake in relation to the growth of 300 normal infants up to 1 year of age in Dudley, Worcestershire, highlights a problem of overnutrition in the group; 50 (16.7%) were found to be suffering from infantile obesity and a further 83 (27.7%) were overweight.During the first three months of life the daily energy intakes of 136 cal/kg body weight for boys and 149 for girls were markedly greater than the level of 120/kg recommended by the Department of Health and Social Security. This coincided with the early addition of solid foods to a full milk intake. 119 babies (39.7%) were offered solids before they were 4 weeks old and 280 (93.3%) before 13 weeks of age. Some babies had solids from the first week after birth. Protein intake was persistently high throughout the first year, and the mean intake of 32.7 g/day was much greater than the intake of 20 g for infants aged up to 1 year recommended by the Department of Health. Standards for fat and carbohydrate intake are not available but in comparison with the levels reported in breast-fed babies intake of fat and carbohydrate was high in the first three months and came closer to the desired level for the former and remained slightly high for the latter in the subsequent age quarters.The relation of childhood and subsequent adult obesity to infant feeding patterns is not yet clear, but there is a high correlation between obese parents and obese and overweight babies; had these babies not been overfed the condition might have been prevented.
