The Family Stress Study - Chronic Stress and Child Adiposity: Testing a Bio-behavioural Model

Pediatric Obesity Clinical Trial

Official title: Family Stress Study: A Longitudinal Observational Study Examining Chronic Stress and Weight Gain Pathways in Young Children.

Status Active, not recruiting

Clinical Trial Summary

The Family Stress Study is following families with young children in Guelph, Hamilton and surrounding areas over 3 years to understand how chronic stress impacts children's weight gain over time and how this association is mediated by alterations in children's cortisol production and weight-related behaviours.

Clinical Trial Description

The Family Stress Study is a longitudinal observational study designed to examine behavioural and biological pathways through which exposure to chronic stress may impact excess weight gain in young children. This study will examine whether exposure to chronic stressors, i.e., household chaos, negative life events, food insecurity, and parental depression, is directly associated with higher weight gain among children. This study will also examine whether alterations in children's cortisol production and weight-related behaviours, i.e., dietary intake, eating behaviour, physical activity, sedentary behaviours and sleep, mediate the stress-weight gain link in young children. This research will also identify whether the quality of caregiver relationships, child sex, family social support, family social connection, or caregiver education moderate the pathways linking stress and excess weight gain. To achieve our aims, 300 children aged 2 to 6 years from families in the Guelph and Hamilton areas will be recruited to examine key behavioural and biological pathways through which exposure to chronic stress may impact weight gain. Our study will also examine the impact of chronic stress on children's mental health, which is a secondary outcome of our study. Understanding which sources of stress and the key behaviours that have the greatest impact on obesity risk among chronically stressed children will aid in the development of effective obesity prevention interventions for specific families. Additionally, this study is well-poised to examine how family stressors during the COVID-19 pandemic influenced children's health behaviours and resulting weight outcomes. Further examination of COVID-19-related stressors, i.e., quarantine or illness due to COVID-19, employment in essential services, general stress, food insecurity, financial insecurity and employment change due to COVID-19, impact cortisol levels and health behaviours and resulting weight outcomes in children. We will also examine how factors such as family social connection or social support, may moderate the impact of the stressors due to COVID-19 on child health. This information will guide strategies to support families in the post-COVID-19 context. ;
