Insights
Family meals and parental care are linked to lower child body mass index (BMI). These factors may help prevent childhood obesity by influencing weight and weight gain over time.
Area of Science:
- Pediatric Health
- Childhood Obesity Research
- Family Studies
Background:
- Childhood obesity is a growing public health concern with complex etiological factors.
- Understanding the role of family environment in weight development is crucial for effective interventions.
Purpose of the Study:
- To examine associations between family characteristics and children's body mass index (BMI) and waist-to-height ratio (WHtR).
- To investigate both cross-sectional and longitudinal relationships over a two-year period.
Main Methods:
- Prospective follow-up study in the Helsinki region with 550 children (aged 9-11 at baseline).
- Data collected in 2006 and 2008, including anthropometric measurements and family characteristic questionnaires.
- Analysis focused on predicting BMI and WHtR based on family factors.
Main Results:
- Increased family meals, positive mealtime parenting, and less unsupervised time predicted lower BMI and slower BMI increase.
- Child's perception of maternal care in 2006 was associated with lower BMI in 2008.
- Fewer associations were observed for waist-to-height ratio (WHtR); physical activity with parents showed no association with BMI or WHtR.
Conclusions:
- Specific family characteristics significantly predict children's BMI and WHtR over a two-year period.
- Findings highlight the significant influence of parental factors on child weight status and weight gain.
- Results provide valuable insights for designing targeted interventions to address childhood obesity.
Objectives:
The objective of this study was to investigate cross-sectional and longitudinal associations between different family characteristics and body mass index (BMI) and waist-to-height ratio (WHtR) in children.
Methods:
This was a prospective follow-up study conducted in Helsinki region with data collected in 2006 and 2008. The sample consisted of 550 children aged 9-11 at baseline. Children were measured and weighed by research staff, and they completed a questionnaire about their family characteristics.
Results:
More meals together with the family, more parenting practices at meals, less time home without adult company after school, and child's perception of receiving care from mother in 2006 predicted a lower BMI in 2008 and partly a smaller increase in BMI from 2006 to 2008. Fewer associations were found to WHtR. Physical activity with either parent was not associated with BMI or WHtR.
Conclusions:
Several family characteristics predicted child BMI and WHtR 2 years later. These results contribute new knowledge about parental influence on child weight and weight gain and should be taken into account when planning interventions on the matter.
