Title: Preventing Early Childhood Obesity, Part 2: Family Spirit Nurture, Prenatal - 18 Months
Brief Summary: This study aims to assess the impact of a home-visiting program, called "Family Spirit Nurture" (FSN), on reducing early childhood obesity in American Indian (AI) children. The FSN intervention targets parent feeding practices, young children's diet and physical activity (PA) and early childhood (0-2 years of age) weight status, all associated with risk for early childhood obesity and, consequently, risk for obesity over the life course. The investigators will also explore whether maternal psychosocial factors (stress, depression and substance use), household food/water security and/or constrained physical activity environments moderate FSN intervention impacts on: mother's feeding behaviors for infants and toddlers; and, children's diets, PA patterns, and weight status. Finally, the investigators will examine how maternal/infant characteristics, diet and behaviors impact the underlying biologic mechanisms of early childhood obesity and whether social and behavioral interventions can impact infant metabolic health. The investigators evaluation will employ a randomized controlled design, in which both the intervention and comparison condition receive assisted transportation to prenatal and well-baby visits (called "Optimized Standard Care"), and the comparison condition also receives potentially beneficial injury prevention education at 8 assessment visits.

Primary Aims:

Efficacy of Family Spirit Nurture (FSN) + Optimized Standard Care (OSC) versus Injury Prevention Education (IPE) + OSC will be assessed for each of the following from birth to 24 months postpartum:

Aim 1. Mothers' implementation of recommended feeding behaviors. Hypothesis 1. FSN + OSC mothers will be more likely to meet breastfeeding and complementary feeding recommendations and engage in responsive parenting/feeding behaviors compared to IPE + OSC mothers.

Aim 2. Children's consumption of healthy diet and physical activity engagement. Hypothesis 2. FSN + OSC children will consume more fruits and vegetables and fewer calories from sugar sweetened beverages (SSB), snacks and desserts, and they will have higher physical activity and reduced screen time/other sedentary activities compared to IPE + OSC children.

Aim 3. Children's weight status. Hypothesis 3. Mean BMI z-scores for FSN + OSC children will be closer to zero (the mean age- and sex- specific BMI z-score for the World Health Organization standard reference population) compared to IPE + OSC children.


Options:
A: % Body Fat (Boys) (Baseline and 3 years); BMI Z-score (Boys) (Baseline and three years); % Body Fat (Girls) (Baseline and 3 years); BMI Z-score (Girls) (Baseline and three years)
B: 1-year, and 3-year changes from baseline in questionaires scores for knowledge, attitudes, and habits of children, parents and teachers in regards to a healthy lifestyle. (3 years)
C: Group differences in percentage of mothers who meet breastfeeding and complementary feeding recommendations and percentage of mothers who introduce sugar sweetened beverages over time as assessed by the Child Feeding Assessment. (2 weeks - 24 months postpartum); Group differences in mean scores for infant feeding style subscales assessed using the Infant Feeding Behavior Questionnaire. (2 months-12 months postpartum); Group differences in in mean scores for toddler feeding style subscales assessed using the Toddler Feeding Behavior Questionnaire (TFBQ). (24 months postpartum); Group differences in children's fruit and vegetable intake, sugar sweetened beverage (SSB) consumption, snacks, and desserts over time. (6 and 24 months postpartum); Group differences in children's physical activity levels as assessed by accelerometry. (18 months-24 months postpartum); Group differences in children's reported physical activity, screen time and other sedentary activities over time as assessed by the Child Physical Activity Assessment. (2 weeks-24 months postpartum); Group differences in children's mean BMI z-scores over time as assessed through child weight and length measurements over time. (2 weeks-24 months postpartum)
D: Change in Children´s Consumption of Foods From Baseline to 3 Months by Intervention Assignment (0, 3 months); Change in Children´s Time of Physical Activity From Baseline to 3 Months by Intervention Assignment (0, 3 months); Change in Score z of Body Mass Index From Baseline to 3 Months by Intervention Assignment (0, 3 month)
