Insights
Childhood obesity is a growing concern. This study found no prenatal weight trends but identified significant postnatal increases in weight and BMI from age five, suggesting a metabolic shift.
Area of Science:
- Pediatrics
- Public Health
- Anthropometry
Background:
- Global concern over rising childhood obesity rates.
- Investigation into the origins of obesity, including prenatal and postnatal factors.
- Examination of the relationship between weight gain and secular trends in height.
Purpose of the Study:
- To determine if childhood obesity trends begin prenatally.
- To analyze the extent to which weight gain relates to secular height trends.
- To assess changes in weight, height, and Body Mass Index (BMI) over time.
Main Methods:
- Comparative analysis of neonatal birth weight data from three Dutch studies (1970-2007).
- Analysis of weight, height, and BMI from two nationwide Dutch studies for postnatal trends.
- Statistical examination of secular trends in anthropometric measurements.
Main Results:
- No significant differences in birth weights were observed between 1970 and 2007.
- Postnatal data revealed increasing trends in weight and BMI from age five onwards in both genders.
- Secular trends in height began around age two and a half, with weight increase being more pronounced than height increase.
- No prenatal secular trend for weight was detected in The Netherlands.
- Postnatal secular trends were evident for weight, height, and BMI, with increased skewness in weight distribution.
Conclusions:
- Childhood obesity trends in The Netherlands do not appear to originate during the prenatal period.
- Significant postnatal increases in weight, height, and BMI are evident from early childhood.
- The pronounced increase in weight compared to height, and altered weight distribution, may indicate underlying metabolic disturbances in the population.
Abstract:
The concern about obesity in children has increased worldwide. The question arises, whether this trend to obesity already starts during the prenatal period and to what extent the increase of weight is related to a secular trend in height. For neonatal data, three studies, performed in The Netherlands, with neonatal data of birth weights were compared. For postnatal data, weight, height and body mass index (BMI) of two nationwide studies, performed in the Netherlands, were analyzed. No differences between birth weights were found between 1970 and 2007. In postnatal data a trend of increasing weight and BMI in both boys and girls starts from five years onwards. The secular trend in height starts from the age of two and a half years onward in both boys and girls. The increase in weight is more pronounced than the increase in height. No prenatal secular trend could be detected in The Netherlands. Postnatal, the secular trend is obvious for weight, height and BMI. The increase in skewness of the weight distribution may be ascribed to a metabolic disturbance of the population.
