Ramasubramanian L et al. – The results show that maternal serious psychological distress is independently associated with early childhood obesity.Methods
- A cross-sectional analysis of data from the Millennium Cohort Study was conducted.
- Subjects consisted of all natural mothers (n= 10 465) who had complete and plausible data for Kessler-6 scores, socio-demographic and anthropometric variables, and their children for whom anthropometric measurements were completed at age 3.
- Maternal serious psychological distress was defined as a score of 13 or more on the Kessler-6 scale.
- Obesity was defined as body mass index >95th centile of the 1990 reference chart for age and sex in children. The data were analysed using spss 16.
- Maternal socio-demographic factors that are known to influence maternal mental health and child obesity were identified and adjusted using multivariate logistic regression.
- Of the 10 465 mother–child dyads, 3.5% of mothers had serious psychological distress and 5.5% of children were obese at 3 years of age.
- Logistic regression analysis showed that maternal serious psychological distress was associated with early childhood obesity (P= 0.01; OR 1.62, 95% CI 1.11, 2.37).
- After adjusting for potential confounding factors using multivariate logistic regression, maternal serious psychological distress remained significantly associated with early childhood obesity (P= 0.01; OR 1.59, 95% CI 1.08, 2.34).
