Insights
Home environment characteristics significantly influence preschool children's physical activity and dietary habits. Modifiable factors like parental behavior and home attributes can be targeted for childhood obesity prevention.
Area of Science:
- Pediatric Health
- Environmental Health
- Nutritional Science
Background:
- Childhood obesity is a growing public health concern.
- The home environment plays a crucial role in shaping early life behaviors.
- Understanding home environment influences is key for effective interventions.
Purpose of the Study:
- To investigate the association between home environment characteristics and preschool children's physical activity.
- To examine the relationship between home environment factors and children's dietary patterns.
- To identify modifiable home-based factors for childhood obesity prevention.
Main Methods:
- Direct observation and parent interviews in 280 preschool children's homes.
- Assessment of physical and nutritional home environment characteristics.
- Measurement of children's physical activity, sedentary behavior, and diet via parent-report questionnaires.
Main Results:
- Parental physical activity, backyard size, and outdoor play equipment correlated with increased outdoor play.
- Fewer TV rules and presence of gaming consoles linked to higher indoor sedentary time.
- Dietary patterns were associated with food availability, parental restrictions (e.g., sugary drinks, snacks), and feeding practices.
Conclusions:
- Home physical attributes and parental behaviors significantly impact children's activity and eating habits.
- These identified factors are largely modifiable.
- Targeting these home environment variables offers potential for childhood obesity prevention and management strategies.
Objective:
To assess relationships between characteristics of the home environment and preschool children's physical activity and dietary patterns.
Methods:
Homes of 280 preschool children were visited and information obtained by direct observation and parent interview regarding physical and nutritional characteristics of the home environment. Children's physical activity, sedentary behaviour and dietary patterns were measured using standardised parent-report questionnaires. Associations were analysed using analysis of variance and correlation.
Results:
Parental physical activity (p = 0.03-0.008), size of backyard (p = 0.001) and amount of outdoor play equipment (p = 0.003) were associated with more outdoor play. Fewer rules about television viewing (p < 0.001) and presence of playstation (p = 0.02) were associated with more indoor sedentary time. Higher fruit and vegetable intake was associated with restricting children's access to fruit juice (p = 0.02) and restricting high fat/sugar snacks (p = 0.009). Lower intake of non-core foods was associated with restricting children's access to fruit juice (p = 0.007), cordial/carbonated drinks (p < 0.001) and high fat/sugar snacks (p = 0.003). Lower fruit and vegetable intake was associated with reminding child to 'eat up' (p = 0.007) and offering food rewards to eat main meal (p = 0.04). Higher intake of non-core foods was associated with giving food 'treats' (p = 0.03) and offering food rewards to eat main meal (p = 0.04). The availability of food groups in the home was associated with children's intake of these foods (fruit and vegetables, p < 0.001; fat in dairy, p = <0.001; sweetened beverages, p = 0.004-<0.001; non-core foods, p = 0.01-<0.001).
Conclusion:
Physical attributes of the home environment and parental behaviours are associated with preschool children's physical activity, sedentary behaviour and dietary patterns. Many of these variables are modifiable and could be targeted in childhood obesity prevention and management.
