Parents labor supply and childhood obesity: Evidence from Scotland

Area of Science:

• Pediatric Health
• Public Health
• Socioeconomics

Background:

• Childhood obesity is a global epidemic, affecting over a third of children worldwide.
• Obesity is the most common chronic childhood disease, with significant short- and long-term health and societal consequences.
• Parental employment factors are increasingly recognized as potential influences on child weight status.

Purpose of the Study:

• To investigate the association between parental employment (extensive and intensive margins) and children's body mass index (BMI) z-score.
• To determine the impact of maternal working hours on the likelihood of children being overweight or obese.
• To explore the mediating mechanisms, such as physical activity and screen time, linking parental employment to child weight outcomes.

Main Methods:

• Analysis of child BMI z-scores and weight status categories in Scotland.
• Examination of the relationship between maternal employment hours and child weight indicators.
• Investigation of potential pathways including child physical activity levels and television viewing habits.

Main Results:

• A positive association was found between maternal hours worked and child BMI z-scores.
• Increased maternal working hours were linked to a higher probability of children being classified as overweight or obese.
• The study identified reduced child physical activity and increased screen time as key mechanisms mediating this relationship.

Conclusions:

• Maternal employment, specifically longer working hours, is associated with adverse child weight outcomes.
• Policy interventions aimed at improving child weight should consider the role of parental employment and its impact on children's lifestyle behaviors.
• Understanding these socioeconomic determinants is crucial for developing effective public health strategies against childhood obesity.
