A systematic review of home-based childhood obesity prevention studies

BACKGROUND AND OBJECTIVES: Childhood obesity is a global epidemic. Despite emerging research about the role of the family and home on obesity risk behaviors, the evidence base for the effectiveness of home-based interventions on obesity prevention remains uncertain. The objective was to systematically review the effectiveness of home-based interventions on weight, intermediate (eg, diet and physical activity [PA]), and clinical outcomes. METHODS: We searched Medline, Embase, PsychInfo, CINAHL, clinicaltrials.gov, and the Cochrane Library from inception through August 11, 2012. We included experimental and natural experimental studies with ≥1-year follow-up reporting weight-related outcomes and targeting children at home. Two independent reviewers screened studies and extracted data. We graded the strength of the evidence supporting interventions targeting diet, PA, or both for obesity prevention. RESULTS: We identified 6 studies; 3 tested combined interventions (diet and PA), 1 used diet intervention, 1 combined intervention with primary care and consumer health informatics components, and 1 combined intervention with school and community components. Select combined interventions had beneficial effects on fruit/vegetable intake and sedentary behaviors. However, none of the 6 studies reported a significant effect on weight outcomes. Overall, the strength of evidence is low that combined home-based interventions effectively prevent obesity. The evidence is insufficient for conclusions about home-based diet interventions or interventions implemented at home in association with other settings. CONCLUSIONS: The strength of evidence is low to support the effectiveness of home-based child obesity prevention programs. Additional research is needed to test interventions in the home setting, particularly those incorporating parenting strategies and addressing environmental influences.

Neighborhood and Parental Influences on Diet and Physical Activity Behaviors in Young Low-Income Pediatric Patients

This study explores the relationship between neighborhood characteristics and caregiver preferences for establishing diet and physical activity behaviors among low-income African American and Hispanic young children (2-5 years). Primary caregivers of young children were recruited from 2 urban pediatric clinics to participate in focus groups (n = 33). Thematic analysis of transcripts identified 3 themes: neighborhood constraints on desired behaviors, caregivers’ strategies in response to neighborhoods, and caregivers’ sense of agency in the face of neighborhood constraints. This study elucidates the dynamic relationship between neighborhoods and caregiver preferences, their interrelated impacts on establishment of diet and physical activity behaviors among young children, and the important role of caregiver agency in establishing behaviors among young children. To effectively address obesity disparities among young children, primary care behavioral interventions must leverage and support such resilient caregiver responses to neighborhood constraints in order to optimally address racial/ethnic and socioeconomic disparities in obesity among young children.

The association between parent-reported provider communication quality and child obesity status: Variation by parent obesity and child race/ethnicity

OBJECTIVE To examine the association between healthcare provider communication quality and child obesity status, and the role of parent obesity and child race/ethnicity regarding this association. METHODS We conducted a cross-sectional secondary data analysis with the 2011-2013 Medical Expenditures Panel Survey of parents with children ages 6-12 (n=5390). We used multivariable logistic regression to examine the association of parent-reported healthcare provider communication quality (explaining well, listening carefully, showing respect, and spending enough time) with child obesity status, and effect modification by parent obesity and child race/ethnicity. RESULTS Parents of obese children were more likely to report that their childs healthcare provider listened carefully (OR=1.41, p=0.002) and spent enough time (OR=1.33, p=0.022) than parents of non-obese children. Non-obese parents of obese children experienced better communication in the domains of listening carefully (p<0.001) and spending enough time (p=0.007). Parents of obese non-Hispanic Asian children and non-Hispanic Black children were more likely to report that providers explained things well (p=0.043) and listened carefully (p=0.012), respectively. CONCLUSION Parents of obese children experienced better communication if parents were non-obese or children were non-Hispanic Black or Asian. PRACTICE IMPLICATIONS Healthcare providers should ensure effective communication with obese parents of obese children.

Assessing the Relationship between Parental Activation and Obesity-related Health Behaviors among a Racially/Ethnically Diverse Population of Low-income Pediatric Patients: A Cross-sectional Study (Preprint)

Background Despite a recent decline in the obesity prevalence among preschool-aged children, obesity remains disproportionately high among children from low-income racial or ethnic minority families. Promoting healthy lifestyles (eg, obesity-preventative behaviors) in primary care settings is particularly important for young children, given the frequency of preventative health visits and parent-provider interactions. Higher adoption of specific health behaviors is correlated with increased patient activation (ie, skill, confidence, and knowledge to manage their health care) among adults. However, no published study, to date, has examined the relationship between parental activation and obesity-related health behaviors among young children. Objective The goal of this study is to measure parental activation in low-income parents of preschoolers in 2 large health systems and to examine the association with diet, screen-time, and physical activity behaviors. Methods We will conduct a cross-sectional study of parents of preschool-aged patients (2-5 years) receiving primary care at multiple clinic sites within 2 large health care systems. Study participants, low-income black, Hispanic, and white parents of preschool-aged patients, are being recruited across both health systems to complete orally administered surveys. Results Recruitment began in December 2017 and is expected to end in May 2018. A total of 267 low-income parents of preschool-aged children have been enrolled across both clinic sites. We are enrolling an additional 33 parents to reach our goal sample size of 300 across both health systems. The data analysis will be completed in June 2018. Conclusions This protocol outlines the first study to fully examine parental activation and its relationship with parent-reported diet, physical activity, and screen-time behaviors among low-income preschool-aged patients. It involves recruitment across 2 geographically distinct areas and resulting from a partnership between researchers at 2 different health systems with multiple clinical sites. This study will provide new knowledge about how parental activation can potentially be incorporated as a strategy to address childhood obesity disparities in primary care settings.
