Weight Status Measures Collected in the Healthy Communities Study: Protocols and Analyses

Area of Science:

• Public Health
• Epidemiology
• Community Health

Background:

• Childhood obesity is a significant public health concern.
• Community programs and policies play a role in obesity prevention.
• Assessing the effectiveness of these interventions requires robust data collection.

Purpose of the Study:

• To detail the protocol for collecting anthropometric data in the Healthy Communities Study.
• To describe the data analysis procedures for obesity-related outcomes.
• To establish a framework for evaluating community-level obesity prevention strategies.

Main Methods:

• Collected height, weight, and waist circumference from children and height/weight from adults during in-home visits.
• Adapted National Health and Nutrition Examination Survey protocols for home-based data collection.
• Utilized retrospective medical record data to calculate Body Mass Index (BMI) and BMI z-score trajectories.
• Implemented rigorous data accuracy checks, including range validation, pattern review, and dual abstractor agreement for medical records.

Main Results:

• The study successfully collected anthropometric data from a large cohort.
• Established procedures for ensuring data accuracy in a community-based setting.
• Generated data suitable for calculating BMI and BMI z-score trajectories.

Conclusions:

• The developed protocol provides a reliable method for collecting anthropometric data in community settings.
• Longitudinal data will enable researchers to investigate associations between community characteristics and childhood obesity.
• This research supports evidence-based strategies for childhood obesity prevention through community interventions.
