There is need to identify evidence-based early childhood obesity prevention programs that are feasible and demonstrate cost-effectiveness for a broader health impact. This scale-out study leveraged community-engaged principles to compare the feasibility and cost-effectiveness of three delivery modes of a childhood obesity prevention family meals program (Simple Suppers) that demonstrated positive impacts on child and caregiver diet/nutritional health-related outcomes in a previous experimental trial tested among elementary-aged children. This three-arm (in-person, online, hybrid) pre-(T0) and post-(T1)-test study included families recruited from Head Start.

Topic: Early-life experiences, the transmission of health and disease within families, and the influence of cumulative risks as well as protective factors throughout life shape the trajectory of health, including mental health. Long-term health trajectories established early in life are influenced by biologic, social, and environmental factors. Negative trajectories may be more salient if exposures to adversity occur during critical developmental periods.

Introduction: This paper presents a pilot lifestyle behavior intervention effect on gestational weight gain and maternal and neonatal outcomes and intervention acceptability.

Materials And Methods: Overweight or obese pregnant participants (N = 70) were randomized to the intervention or usual care group. The 20-week intervention integrated Hope theory and goal-oriented episodic future thinking (GoEFT) to prevent excessive gestational weight gain through stress and emotion management, healthy eating, and physical activity.

Background: Dietary intake of micronutrients and essential fatty acids in overweight or obese pregnant women during early pregnancy is unknown. We investigated the proportion of pregnant women meeting recommendations for dietary intake of micronutrients and essential fatty acids and compared stress and depressive symptoms between those meeting and below recommendations.

Methods: Participants (N = 70) were overweight or obese pregnant women ≤16 weeks gestation.

Background: Depressive symptoms are particularly prevalent among low-income overweight or obese mothers with young children, indicating the importance of understanding and addressing this serious health condition. Although lifestyle behavior interventions are promising for alleviating depressive symptoms in low-income overweight or obese mothers with young children, mechanisms underlying the association between these interventions and depressive symptoms in this priority population remain unknown.

Objective: A secondary analysis of data from a randomized controlled trial that tested a 16-week community-based lifestyle behavior intervention for low-income overweight or obese mothers with young children was conducted to examine whether autonomous motivation, coping self-efficacy, and emotional coping mediated the association between the intervention and depressive symptoms.

This secondary analysis study addressed a gap of knowledge: whether perceived stress reduction created by a lifestyle intervention might serve as a mediator for reducing fat and fast food intakes in low-income overweight or obese mothers of young children. This analysis included 338 low-income overweight or obese mothers of young children who completed a phone interview immediately after the 16-week lifestyle intervention. Valid surveys were used to assess perceived stress and fat and fast food intakes.

Purpose: We investigated whether autonomous motivation and self-efficacy might mediate the association between a lifestyle behavior intervention and dietary fat intake in low-income overweight or obese women with young children.

Methods: Participants were randomized to an intervention or comparison group. Intervention participants received a 16-week intervention aimed to prevent weight gain through promotion of stress management, healthy eating and physical activity.

Using data from a community-based lifestyle behavioral intervention study, this secondary data analysis investigated whether emotional coping, coping self-efficacy, and autonomous motivation mediated the association between the intervention and perceived stress in low-income overweight or obese mothers of young children. Results showed that coping self-efficacy significantly mediated the association between the intervention and perceived stress. However, emotional coping and autonomous motivation did not significantly mediate the association between intervention and perceived stress.
