Methods and design of a 10-week multi-component family meals intervention: a two group quasi-experimental effectiveness trial

Improving public health sector service delivery in the Free State, South Africa: development of a provincial intervention model

Background

Public health sector service delivery challenges leading to poor population health outcomes have been observed in the Free State province of South Africa for the past decade. A multi-method situation appraisal of the different functional domains revealed serious health system deficiencies and operational defects, notably fragmentation of healthcare programmes and frontline services, as well as challenges related to governance, accountability and human resources for health. It was therefore necessary to develop a system-wide intervention to comprehensively address defects in the operation of the public health system and its major components.

Methods

This study describes the development of the ‘Health Systems Governance & Accountability’ (HSGA) intervention model by the Free State Department of Health (FSDoH) in collaboration with the community and other stakeholders following a participatory action approach. Documented information collected during routine management processes were reviewed for this paper. Starting in March 2013, the development of the HSGA intervention model and the concomitant application of Kaplan and Norton’s (1992) Balanced Scorecard performance measurement tool was informed by the World Health Organization’s (2007) conceptual framework for health system strengthening and reform comprised of six health system ‘building blocks.’ The multiple and overlapping processes and actions to develop the intervention are described according to the four steps in Kaplan et al.’s (2013) systems approach to health systems strengthening: (i) problem identification, (ii) description, (iii) alteration and (iv) implementation.

Results

The finalisation of the HSGA intervention model before end-2013 was a prelude to the development of the FSDoH’s Strategic Transformation Plan 2015–2030. The HSGA intervention model was used as a tool to implement and integrate the Plan’s programmes moving forward with a consistent focus on the six building blocks for health systems strengthening and the all-important linkages between them.

Conclusion

The model was developed to address fragmentation and improve public health service delivery by the provincial health department. In January 2016, the intervention model became an official departmental policy, meaning that it was approved for implementation, compliance, monitoring and reporting, and became the guiding framework for health systems strengthening and transform in the Free State.

Caregiver Nutritional Health Outcomes of the Simple Suppers Study: Results from a 10 Week, Two-Group Quasi-Experimental Family Meals Intervention

Individuals from racial minority backgrounds, especially those in low income situations, are at increased risk for obesity. Family meals positively impact child nutritional health; however, there is limited evidence examining the impact on caregivers, particularly racial minority and income-restricted individuals. The objective of this intervention study was to determine the effect of Simple Suppers, a 10 week family meals program, on caregiver diet and nutrition outcomes. Intervention versus waitlist control participants were compared from baseline (T0) to post-intervention (T1). In addition, intervention participants were assessed at a 10 week follow-up time point (T2). This study was a two-group quasi-experimental intervention trial. Lessons (10 total) were delivered on a weekly basis for 90 min. Data were collected from intervention and waitlist control participants at T0 and T1, and intervention participants at T2. After baseline (T0) data collection, families enrolled in the immediate upcoming session of Simple Suppers (intervention group) or waited for 10 weeks (waitlist control group) to begin the program. Participants were caregivers of children ages 4–10 years. This study was conducted in a faith-based community center for underserved families in Columbus, Ohio. Primary outcomes were: diet quality assessed by Healthy Eating Index (HEI) total and component scores, and total energy intake (kcal/day); body mass index (BMI) (kg/m²), waist circumference (cm), systolic and diastolic blood pressure (BP) (mmHG); and self-efficacy for having healthy meals and menu planning (both scalar). The impact of the intervention (T0:T1) was assessed using generalized mixed-effects linear regression models. Maintenance of change in study outcomes among intervention participants (T1:T2) was examined with paired t-tests. 109 caregivers enrolled in this study. The retention rate at T1 was 90% (i.e., 98 participants). 56 of 68 intervention participants completed T2, resulting in a retention rate of 82%. Almost all (99%) were female, 61% were Black, and 50% were between 31 and 40 years old. In total, 40% had low income and 37% had low or very low food security. At T1, intervention vs. waitlist controls had a lower daily energy intake (p = 0.04), but an HEI-2010 component score for fatty acids (adequacy) that was lower indicating a lower dietary intake of fatty acids (p = 0.02), and a component score for empty calories (moderation) that was significantly lower indicating a higher intake of empty calorie foods (p = 0.03). At T1, intervention vs. waitlist controls also had a lower BMI (p < 0.001) and systolic BP (p = 0.04), and higher self-efficacy (p = 0.03). There were no group differences in other outcomes. At T2, intervention participants maintained the changes in daily energy intake, BMI, systolic BP, and self-efficacy that improved during the intervention period. There was no change (improvement) in the component score for fatty acids; however, the component score for empty calories significantly improved (p = 0.02). Engagement in the Simple Suppers program led to improvements in caregivers’ daily caloric intake, weight status, systolic blood pressure, and self-efficacy for family meals. Future research should further explore the dietary and nutritional health benefits of family meals among caregivers at the highest risk for obesity.

Religion and Food Insecurity in the Time of COVID-19: Food Sovereignty for a Healthier Future

The COVID-19 pandemic has exposed and amplified food insecurity in marginalized communities of color, revealing systemic health and socioeconomic inequalities. Given the role that religious organizations play in building social capital, disseminating information to local communities, and facilitating the distribution of basic necessities such as food, they are integrally involved in short- and long-term solutions to food insecurity. Yet, literature on the role of religious institutions for mitigating food insecurity is limited. The literature related to methods and means by which religious organizations engage community efforts to mitigate food security as well as studies in food sovereignty will be reviewed.

Child diet and health outcomes of the simple suppers program: a 10-week, 2-group quasi-experimental family meals trial

BACKGROUND

Racial minority children, particularly from low-income households, are at risk for obesity. Family meals have a protective effect on child nutritional health. However, the current evidence is limited in racial and socioeconomic diversity. The objective of this study was to evaluate the impact of a family meals intervention, Simple Suppers, on improvements in diet and health outcomes from baseline (T0) to post-intervention (T1) in intervention compared to waitlist control participants, and determine retention of change in outcomes among intervention participants at 10-week follow-up (T2).

METHODS

Simple Suppers was a 10-week family meals intervention implemented as a 2-group quasi-experimental trial. Ten 90-min lessons were delivered weekly. Data were collected at T0 and T1, and from intervention participants at T2. Participants were racially diverse 4-10 year-old children from low-income households. Setting was a faith-based community center. Main outcomes were daily servings of fruit, vegetables, and sugar-sweetened beverages and diet quality; z-scores for body mass index (BMI), waist circumference, systolic and diastolic blood pressure (BP); weight status categories; food preparation skills; and family meals (frequency of dinner, breakfast, TV viewing during meals, meals in dining area). Generalized linear mixed models (GLMMs) and mixed-effects ordinal regression models were used to assess intervention impact (T0:T1). Paired t-tests examined retention of change among intervention participants (T1:T2).

RESULTS

One hundred forty children enrolled and 126 completed T1 (90% retention); 71 of 87 intervention participants completed T2(79% retention). Mean (SD) age was 6.9(1.9) yr, 62% female, 60% Black, and 42% low-income. Intervention vs waitlist controls had higher food preparation skills (p < 0.001) and lower TV viewing during meals (p = 0.04) at T1.There were no group differences in dietary intake or quality or z-scores for BMI, waist circumference, or BP, however intervention versus waitlist controls experienced a greater change toward healthy weight (p = 0.04) At T2, intervention participants demonstrated a retention of improved food preparation skills.

CONCLUSIONS

Simple Suppers led to improvements in children's weight status, food preparation skills, and TV viewing during meals, but not diet or z-scores for BMI, waist circumference, or BP. Future research should examine the preventive effects of healthy family mealtime routines in children at greatest risk for obesity.
