简要总结

The purpose of this research study is to evaluate two different Parents as Teachers curriculums taught by parent educators, during home visits. The control curriculum includes only the standard PAT lessons; the intervention curriculum includes the standard PAT lessons plus additional information about how families can live healthy and active lives while reaching a healthy weight. The investigators hypothesize the intervention lessons will change the way people eat and/or their activity level.

详细描述

The primary aim is to test Healthy Eating & Active Living Taught at Home (HEALTH), which adapts and integrates the Diabetes Prevention Program lifestyle intervention within Parents As Teachers (PAT), a national home visiting program on which many high needs populations rely for parent-child information and services. Specific aims 1 and 2 will evaluate the impact of HEALTH on lifestyle behaviors and weight of obese mothers and their overweight/obese preschool child across multiple PAT regions. Specific aims 3 and 4 will address elements of external validity through evaluation of factors that impact the uptake of HEALTH within the PAT organization.

Specific aim 1. Using a group randomized, nested cohort design, evaluate the impact of HEALTH on obese women (BMI 30-45 kg/m2; age 18-45 y old) randomized to either control regions receiving the standard PAT program, or intervention regions receiving HEALTH.

Hypothesis 1.1 The primary hypothesis is at the conclusion of the study, when compared to the control group, participants in HEALTH will achieve a 7% weight loss at 12 months and maintain a 5% weight loss at 24 months, which will be at least two-fold greater than that achieved in the control group.

The secondary hypotheses are that at the conclusion of the study, when compared to the control group, participants in HEALTH will significantly:

Hypothesis 1.2 Improve clinical outcomes of waist circumference and systolic and diastolic blood pressure; Hypothesis 1.3 Improve knowledge of evidence-based lifestyle behaviors and quality of life; Hypothesis 1.4 Decrease caloric intake Hypothesis 1.5 Increase moderate intensity walking.

结局指标

主要结局

Body Mass Index

时间窗: Change in BMI from baseline to 24 months

Body mass index (BMI) will be used to classify participants as "obese". The investigators will calculate the BMI from weight and height measurements. Participants weight measurement will be obtained using a calibrated scale placed on a solid flat surface. The screener will record the weight in pounds. Height measurement will be the maximum vertical height measured using a stadiometer on a solid flat surface with a fixed vertical backboard and an adjustable headpiece or an approved portable stadiometer on a solid flat surface with an adjustable headpiece.

次要结局

  • Blood Pressure(Change in blood pressure from baseline to 24 months)
  • Waist Circumference(Change in waist circumference from baseline to 24 months)
  • Survey(Changes in surveys from baseline to 24 months)
