Feasibility of Meal Delivery Postpartum

Proportion of received weekly study meals participants reported consuming each week collected via weekly electronic surveys in which participants will self-report the number of study meals a) they consumed, b) other household members consumed, or c) that were uneaten.

Time frame: Collected weekly from intervention start (6-45 weeks postpartum) to follow-up (14-53 weeks postpartum)

Population: The total number of meals received were analyzed to determine the average proportion of provided study meals the participant reportd they ate, others in the household ate, and that were thrown away/frozen/uneaten per week. One participant did not receive meals for 2 weeks due to delivery errors, which is why the total units analyzed is 620.

To assess satisfaction with the study intervention, the 28-item Diet Satisfaction Questionnaire (DSAT-28) will be used in which participants respond to 28 statements using a 5-point Likert scale. Responses to all 28-items are averaged to produce a total diet satisfaction score (designed to reflect satisfaction as it relates to following a weight-management diet) ranging from 1-5. Subscale scores for Cost Factor (reflects financial cost of the diet) and Planning & Preparation Factor (reflects amount of time and effort spent in planning and preparing) will also be calculated and range from 1-5. For the overall diet satisfaction score and subscale scores, higher scores represent greater satisfaction. Changes in overall diet satisfaction, as well as changes in subscale scores for Cost Factor and Planning & Preparation Factor will be examined from baseline to follow-up.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: Change calculated as score at 8-week follow up minus score at baseline, with positive values indicating an increase in score (which reflects an increase in satisfaction) from baseline to follow up.

The number of enrolled participants who completed some or all follow-up assessment visit measurements.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: The overall number of participants analyzed (N=11) reflects the number of participants who enrolled in the study, including those who completed all of the 8-week follow-up assessment measurements, those who completed some (but not all) of the 8-week follow-up assessment measurements, and those that did not complete any of the 8-week follow-up assessment.

Total number of eligible subjects who agreed to participate out of those who were screened.

Time frame: baseline (5-45 weeks postpartum)

Population: The overall Number of Participants Analyzed (N=24) reflects the total number of participants who were screened, including those who may not have been eligible/consented into the study.

Determined using the 18-item United States (US) Household Food Security Survey Module based on the previous 30 days. Adult food security scores range from 0 to 10, with lower values indicating greater food security.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: Change calculated as food security score at 8-week follow up minus score at baseline, with negative values indicating an increase in food security from baseline to follow up.

Participants will be asked to score 3 statements on a 5-point Likert scale ranging from 1=very sure to 5=very unsure (adapted from Lipsky LM et al. 2016). Responses are reverse coded and averaged, so higher scores reflect increasing self-efficacy.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: Change calculated as score at 8-week follow up minus score at baseline, with positive values indicating an increase in self-efficacy from baseline to follow up.

Determined using the 10-item Perceived Stress Scale (PSS-10) based on the last month. PSS-10 scores range from 0 to 40, with higher scores representing higher levels of perceived stress.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: Change calculated as score at 8-week follow up minus score at baseline, with positive values indicating an increase in perceive stress score from baseline to follow up.

Body weight measured at baseline and follow-up will be used to calculate weight change.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: Change calculated as weight at 8-week follow up minus weight at baseline, with negative values indicating weight loss from baseline to follow up.

Participants will be asked to score 3 statements on a 5-point Likert scale ranging from 1=very sure to 5=very unsure (adapted from Lipsky LM et al. 2016). Responses are reverse coded and averaged, so higher scores reflect increasing self-efficacy.

Time frame: baseline (5-45 weeks postpartum), follow-up (14-53 weeks postpartum)

Population: Change calculated as score at 8-week follow up minus score at baseline, with positive values indicating an increase in self-efficacy from baseline to follow up.
