Introduction:
Adherence to dietary recommendations among Latinx adolescents is low, contributing to an increased risk for obesity and cardiometabolic disease. Parents play a crucial role in adolescents’ disease risk and diet quality due to their role in modeling healthful behaviors and providing food. However, information about how parental monitoring and eating-related parenting practices are associated to cardiovascular risk is scarce.

Hypothesis:
We hypothesized that unhealthful parenting practices would be associated with higher cardiometabolic risk factors among Latinx adolescents.

Methods:
We included 61 parent-adolescent (6
th
-8
th
grade) Latinx dyads. Parents self-reported information about parental monitoring, family eating habits (use of media during meals, inclusion of specific foods during dinner, fast food intake), parental feeding style, and parental energy index (whether parents have had conversations with their children regarding weight and healthful diet and physical activity behaviors). Adolescent cardiometabolic risk factors measured include blood pressure (BP), total cholesterol, and HbA1c. Age- and sex-adjusted BMI percentile (BMI%) and z-scores (BMIz) were calculated from weight and height measurements. Associations between parental practices and cardiometabolic risk factors were analyzed using linear regression (B) and correlation (r).

Results:
Adolescents’ measured risk factors were as follows: SBP=106±11 mm Hg, DBP=62±7 mm Hg, weight=61±15 kg, BMI%=83±20, BMIz=1.2±0.9, HbA1c=5.1±0.4 %, and total cholesterol=164±12 mg/dL. Use of media during meals (e.g., TV, electronic devices) was associated with higher adolescent weight (B=7.97; r=.31; p=.02) and BMIz (B=.37; r=.27, p=.05). Parental restrictive feeding style was associated with higher adolescent weight (B=5.54; r=.22; p=.03), BMI% (B=13.19; r=.52, p=.001) and diastolic BP (B=2.50; r=.27, p=.04). Adolescent children of parents reporting a greater parental energy index had a greater body weight (B=6.90; r=.46; p=.001) and BMI % (B=6.28; r=.33, p=.01). Parent-reported frequency of consuming family meals, frequency of fast food meals, importance of consuming family meals, and inclusion of vegetables, fruit and 100% juice, milk, and sugar-sweetened beverages during family meals were not associated with adolescents’ BMI or BP. Associations with other risk factors were not significant.

Conclusions:
Results suggest that unhealthful parenting practices such as restrictive feeding and allowing the use of media during meals may negatively influence cardiometabolic risk factors among Latinx adolescents. Parents of children with a greater BMI reported having more conversations about weight and healthful behaviors with their children. Future family-based behavioral interventions for this population should incorporate more parenting strategies as part of their curricula.
