Improving parental recognition of childhood overweight: The Map Me Study

Do mothers accurately identify their child's overweight/obesity status during early childhood? Evidence from a nationally representative cohort study

Background

Maternal recognition of overweight/obesity during early childhood is a key determinant in achieving healthy weight status in children. The aim of this study is to 1) investigate maternal perceptions of their child weight, focusing on whether or not mothers accurately identify if their child is overweight or obese at three years old and five years old; 2) identify the factors influencing maternal misperceptions regarding their child’s weight at three years old and five years old, 3) ascertain if a failure to recognize overweight/obesity at three years old is associated with the likelihood of doing so at five years old.

Methods

Using two waves of the longitudinal Growing Up in Ireland study data regarding child, maternal, and household characteristics as well as healthcare access and utilization variables were obtained for mothers when their children are three and five years old respectively. Multivariate logistic analysis was used to examine the factors associated with mothers inaccurately perceiving their child to be of normal weight status when the child is in fact either clinically overweight or obese.

Results

In wave 2, 22% of mothers failed to accurately identify their child to be overweight or obese. This inaccuracy decreased to 18% in wave 3. A failure of mothers to identify their child’s overweight/obesity was more likely to occur if the child was a girl (OR: 1.25) (OR: 1.37), had a higher birth weight (OR:1.00), if the mother was obese (OR: 1.50), (OR: 1.72) or working (OR:1.25) (OR:1.16) in wave 2 and wave 3, respectively. Other factors affecting the odds of misperceiving child’s weight include gestation age, income and urban living.

Conclusion

These findings suggest that mothers of overweight or obese three and five year olds show poor awareness of their child’s weight status. Both child and mother characteristics play a role in influencing this awareness. Mothers unable to accurately identify their child’s overweight or obesity status at three years old are likely to do again when the child is five years old. This study highlights the need for increased support to help improve mothers’ understanding of healthy body size in preschool aged children.

A cluster randomised trial testing an intervention to improve parents' recognition of their child's weight status: study protocol

Background

Parents typically do not recognise their child’s weight status accurately according to clinical criteria, and thus may not take appropriate action if their child is overweight. We developed a novel visual intervention designed to improve parental perceptions of child weight status according to clinical criteria for children aged 4–5 and 10–11 years. The Map Me intervention comprises age- and sex-specific body image scales of known body mass index and supporting information about the health risks of childhood overweight.

Design

This cluster randomised trial will test the effectiveness of the Map Me intervention. Primary schools will be randomised to: paper-based Map Me; web-based Map Me; no information (control). Parents of reception (4–5 years) and year 6 (10–11 years) children attending the schools will be recruited. The study will work with the National Child Measurement Programme which measures the height and weight of these year groups and provides feedback to parents about their child’s weight status. Before receiving the feedback, parents will complete a questionnaire which includes assessment of their perception of their child’s weight status and knowledge of the health consequences of childhood overweight. The control group will provide pre-intervention data with assessment soon after recruitment; the intervention groups will provide post-intervention data after access to Map Me for one month. The study will subsequently obtain the child height and weight measurements from the National Child Measurement Programme. Families will be followed-up by the study team at 12 months. The primary outcome is any difference in accuracy in parental perception of child weight status between pre-intervention and post-intervention at one month. The secondary outcomes include differences in parent knowledge, intention to change lifestyle behaviours and/or seek advice or support, perceived control, action planning, coping planning, and child weight status at 12 month follow-up.

Discussion

The Map Me tool has potential to make a positive impact on children’s health at a population level by introducing it into current intervention programmes to improve accuracy of parental perception of child’s weight status. This trial will inform the action of researchers, educators, health professionals and policy makers.
