Insights
Healthy children born in 2009 showed lower weight and body mass index (BMI) compared to those born in 1993, indicating a negative secular change in these anthropometric measures. Height remained unaffected across both cohorts.
Area of Science:
- Pediatric anthropometry
- Longitudinal growth studies
- Secular trends in child development
Context:
- Investigating changes in child growth patterns over time.
- Comparing anthropometric data of children born 16 years apart (1993 vs. 2009).
- Assessing potential secular changes in healthy pediatric populations.
Purpose:
- To conduct a longitudinal anthropometric study on two distinct cohorts of healthy children (birth to 2 years).
- To analyze secular changes in weight, height, and body mass index (BMI) between 1993 and 2009.
- To compare growth parameters in children born in 1993 versus 2009.
Summary:
- Weight and BMI were significantly higher in the 1993 cohort compared to the 2009 cohort after 6-9 months of age.
- No significant differences in height were observed between the two cohorts.
- The study identified a negative secular trend in weight and BMI for healthy children from 1993 to 2009.
Impact:
- Highlights a significant shift in pediatric weight and BMI trends over 16 years.
- Provides crucial data for understanding contemporary child growth and nutritional status.
- Informs public health strategies related to child development and obesity prevention.
Objective:
To accomplish a longitudinal anthropometric study in two different cohorts of healthy children (from birth to 2 years of age) who were born in 1993 and 2009. The possible appearance of secular changes within this period is analyzed.
Material And Methods:
Weight, height and body mass index (BMI) at birth and ages 3, 6, 9, 12, 15, 18 and 24 months in two different cohorts of healthy children born in 1993 (459 males and 425 females) and 2009 (460 males and 481 females) have been registered and analyzed.
Results:
Average values for weight and BMI in 1993 cohort were significantly higher (p < 0.05) than those in 2009 cohort beyond 6 months of age in females and 9 months of age in males, up to 24 months of age. There were no statistically significant differences among average values of registered height in every period of age within both cohorts.
Conclusions:
The comparison of anthropometric data among two different cohorts of healthy children born in 1993 and 2009 in similar social and health conditions shows a "secular change" in a negative sense regarding weight and BMI, without affecting height.
