Infants with low rate of weight gain. II. A study of environmental factors
Insights
Low infant weight gain is often linked to psychosocial factors, not just organic causes. Adverse family environments significantly correlate with slower growth rates in infants.
Area of Science:
- Pediatrics
- Child Psychology
- Public Health
Background:
- Low rate of weight gain in infants can be a sign of underlying health issues.
- Assessing the influence of the psychosocial environment is crucial for understanding infant growth.
- Previous studies have focused on organic etiologies, with less emphasis on environmental factors.
Purpose of the Study:
- To investigate the clinical significance of a low rate of weight gain in infants.
- To identify potential organic and psychosocial factors associated with subnormal infant growth.
- To explore the correlation between adverse family environments and infant weight gain velocity.
Main Methods:
- Eighty-one infants were studied, categorizing them by weight gain rate (subnormal, low but normal, control).
- Infants with subnormal weight gain were analyzed for organic causes and psychosocial risk factors.
- A psychosocial risk score was developed to quantify adverse family factors.
Main Results:
- Organic etiology was identified in 28% of infants.
- Infants with subnormal weight gain showed overrepresentation of psychosocial risk factors (e.g., unemployment, paternal ill-health).
- A significant negative correlation was found between the psychosocial risk score and the rate of weight gain.
Conclusions:
- Psychosocial factors play a significant role in infant weight gain, independent of organic causes.
- Adverse family environments are strongly associated with subnormal infant growth.
- Clinical evaluation of infants with slow weight gain should include assessment of the psychosocial context.
Abstract:
Eighty-one infants were investigated to evaluate the clinical significance of low rate of weight gain. An organic etiology was found in 28 infants. The remaining infants were analysed with special respect to their psychosocial environment. Growth was assessed by rate of weight gain. Thirty-four infants had subnormal rates. Comparisons were made with 18 infants with low but normal rates and a control group of 72 infants. Several psychosocial risk factors were overrepresented in infants with subnormal rate of weight gain such as unemployment, ill-health in fathers, dependence on social welfare etc. No significant differences were found in perinatal factors except for birth weight. The magnitude of the load of adverse factors within the family was measured as a score. A significant negative correlation was found between the score obtained and the rate of weight gain.
