Associations between Family-Based Stress and Dietary Inflammatory Potential among Families with Preschool-Aged Children.

Chronic stress is known to influence dietary choices, and stressed families often report poorer diet quality; however, little is known about how family-based stress is linked with dietary patterns that promote inflammation. This study investigated associations between family-based stress and the inflammatory potential of the diet among preschool-aged children and their parents. Parents (n = 212 mothers, n = 146 fathers) and children (n = 130 girls, n = 123 boys; aged 18 months to 5 years) from 241 families participating in the Guelph Family Health Study were included in the analyses. Parents reported levels of parenting distress, depressive symptoms, household chaos, and family functioning. The inflammatory potential of parents' and children's diets was quantified using the Dietary Inflammatory Index (DII®), adjusted for total energy intake (i.e., the E-DIITM). E-DII scores were regressed onto family stress using generalized estimating equations to account for shared variance among family clusters. Compared to those in homes with low chaos, parents in chaotic homes had significantly more proinflammatory dietary profiles (ß = 0.973; 95% CI: 0.321, 1.624, p = 0.003). Similarly, compared to those in well-functioning families, parents in dysfunctional families had significantly more proinflammatory dietary profiles (ß = 0.967; 95% CI: 0.173, 1.761, p = 0.02). No significant associations were found between parents' E-DII scores and parenting distress or depressive symptoms, nor were any associations found for children's E-DII scores. Results were not found to differ between males and females. Parents in chaotic or dysfunctional family environments may be at increased risk of chronic disease due to proinflammatory dietary profiles. Children's dietary inflammatory profiles were not directly associated with family stress; however, indirect connections through family food-related behaviours may exist. Future research should prioritize elucidating these mechanisms.

Parent Stress as a Consideration in Childhood Obesity Prevention: Results from the Guelph Family Health Study, a Pilot Randomized Controlled Trial.

Parents' stress is independently associated with increased child adiposity, but parents' stress may also interfere with childhood obesity prevention programs. The disruptions to the family dynamic caused by participating in a behaviour change intervention may exacerbate parent stress and undermine overall intervention efficacy. This study explored how family stress levels were impacted by participation in a home-based obesity prevention intervention. Data were collected from 77 families (56 fathers, 77 mothers) participating in the Guelph Family Health Study (GFHS), a pilot randomized control trial of a home-based obesity prevention intervention. Four measures of stress were investigated: general life stress, parenting distress, depressive symptoms, and household chaos. Multiple linear regression was used to compare the level of stress between the intervention and control groups at post-intervention and 1-year follow-up, adjusted for baseline stress. Analyses for mothers and fathers were stratified, except for household chaos which was measured at the family level. Results indicate no significant differences between intervention and control groups for any stress measure at any time point, indicating a neutral effect of the GFHS intervention on family stress. Future work should investigate the components of family-based intervention protocols that make participation minimally burdensome and consider embedding specific stress-reduction messaging to promote family health and wellbeing.

Stress is Associated with Adiposity in Parents of Young Children.

OBJECTIVE: This study investigated associations between stress (general stress, parenting distress, and household chaos) and adiposity among parents of young children. METHODS: The sample consisted of 49 mothers and 61 fathers from 70 families with young children living in Ontario, Canada. Linear regression using generalized estimating equations was used to investigate associations between stress measures and BMI, waist circumference (WC), waist to height ratio (WHtR), and percent fat mass. RESULTS: General stress was significantly associated with BMI ( ß ^ = 0.54; 95% CI: 0.04-1.03) and WC ( ß ^ = 1.44; 95% CI: 0.10-2.77). Parenting distress was significantly associated with BMI ( ß ^ = 0.16; 95% CI: 0.02-0.31), WC ( ß ^ = 0.39; 95% CI: 0.04-0.75), and WHtR ( ß ^ = 0.003; 95% CI: 0.001-0.005). Household chaos was significantly associated with all adiposity measures (BMI: ß ^ = 0.20 [95% CI: 0.08-0.33]; WC: ß ^ = 0.48 [95% CI: 0.21-0.75]; WHtR: ß ^ = 0.003 [95% CI: 0.001-0.005]; percent fat mass: ß ^ = 0.29 [95% CI: 0.08-0.49]). CONCLUSIONS: General stress, parenting distress, and household chaos are associated with adiposity among parents of young children. Future research should elucidate mechanisms by which this occurs and elucidate how this risk may be mitigated.

The Impact of COVID-19 on Health Behavior, Stress, Financial and Food Security among Middle to High Income Canadian Families with Young Children.

The COVID-19 pandemic has disrupted many aspects of daily life. The purpose of this study was to identify how health behaviors, level of stress, financial and food security have been impacted by the pandemic among Canadian families with young children. Parents (mothers, n = 235 and fathers, n = 126) from 254 families participating in an ongoing study completed an online survey that included close and open-ended questions. Descriptive statistics were used to summarize the quantitative data and qualitative responses were analyzed using thematic analysis. More than half of our sample reported that their eating and meal routines have changed since COVID-19; most commonly reported changes were eating more snack foods and spending more time cooking. Screen time increased among 74% of mothers, 61% of fathers, and 87% of children and physical activity decreased among 59% of mothers, 52% of fathers, and 52% of children. Key factors influencing family stress include balancing work with childcare/homeschooling and financial instability. While some unhealthful behaviors appeared to have been exacerbated, other more healthful behaviors also emerged since COVID-19. Research is needed to determine the longer-term impact of the pandemic on behaviors and to identify effective strategies to support families in the post-COVID-19 context.
