Engaging Fathers for Effective Child Nutrition and Development in Tanzania (EFFECTS): study protocol for a five-arm, cluster-randomized trial

BACKGROUND

Globally, 144 million children under 5 years are undernourished and 250 million do not meet their developmental potential. Multi-input interventions, such as bundled nutrition and parenting interventions, are designed to mitigate risks for multiple child outcomes. There is limited evidence that bundled interventions have additive benefits to nutrition, growth, or development outcomes. These outcomes share common risks; therefore, designing interventions to tackle these risks using a common theory of change may optimize effectiveness. Emerging evidence suggests explicit engagement of fathers may benefit child outcomes, but few trials have tested this or included data collected from fathers.

METHODS

Engaging Fathers for Effective Child Nutrition and Development in Tanzania (EFFECTS) is a community-based cluster-randomized controlled trial that will be implemented in the rural Mara Region, Tanzania. The trial aims (1) to test a bundled nutrition and parenting program delivered to mothers' groups, with or without fathers' groups, over 12 months on child and caregiving outcomes compared to a nutrition program alone, and (2) to test nutrition or bundled nutrition and parenting programs delivered to mothers' and fathers' groups over 12 months on child and caregiving outcomes compared to programs delivered to mothers alone. The trial comprises five arms: (1) mothers' groups receiving a nutrition program, (2) mothers' groups receiving a bundled nutrition and parenting program, (3) mothers' and fathers' groups receiving a nutrition program, (4) mothers' and fathers' groups receiving a bundled nutrition and parenting program, and (5) control receiving standard of care health services. The primary outcomes are child dietary diversity and early child development (mental and motor development). Parents with a child under 18 months will be enrolled in peer groups and receive twice monthly intervention by trained community health workers. Data will be collected from mothers, fathers, and children at baseline (pre-intervention), midline, and endline (post-intervention).

DISCUSSION

EFFECTS will generate evidence on the effects of bundled nutrition and parenting interventions on child nutrition, growth, and development outcomes; determine the benefits of engaging fathers on child, caregiving, and caregiver outcomes; and investigate common and unique pathways between treatments and child outcomes.

Associated factors of malnutrition status among children and adolescents living with HIV in Tanzania: Individual-level analysis and marginal effect estimation

OBJECTIVES

This study aimed to identify individual-level factors that affect malnutrition outcomes among children and adolescents living with HIV/AIDS in Tanzania.

METHODS

We used data from the National AIDS Control Programme. 70,102 participants aged 5 to 19 years attending care and treatment clinics between January to December 2021 were included. Nutritional assessments were performed by anthropometric measurement. Logistic regression models were used to evaluate risk factors. We further estimated marginal prevalence and adjusted predictions by marginal effects. Supplementary analysis assessed the accuracy of the final fitted model.

RESULTS

Prevalence of malnutrition for stunting, underweight, wasting, and anthropometric failure (CIAF) were 36.0%, 28.9%, 13.0%, and 48.0%, respectively. Several individual-level factors were significant determinants of malnutrition. Boys, participants aged 15-19 years, those switched to second- or third-line antiretroviral therapy (ART), initiated ART at ages of 5-14 years, ART duration less than 3 years, and were in advanced stages of WHO HIV clinical status had increased adjusted odds ratios and marginal prevalence. The larger AUC values for all models implied importance of identified factors accounted for malnutrition.

CONCLUSIONS

On long-term ART, nutritional interventions should be context-specific guidelines to improve growth, especially at ART initiation, ART regimen, and ART duration reckoning with age and sex.

Effects of engaging fathers and bundling nutrition and parenting interventions on household gender equality and women's empowerment in rural Tanzania: Results from EFFECTS, a five-arm cluster-randomized controlled trial

Advancing gender equality and women's empowerment (GE/WE) may contribute to better child nutrition and development in low-resource settings. However, few empirical studies have generated evidence on GE/WE and examined the potential of engaging men to transform gender norms and power relations in the context of nutrition and parenting programs. We tested the independent and combined effects of engaging couples and bundling nutrition and parenting interventions on GE/WE in Mara, Tanzania. EFFECTS (ClinicalTrials.gov, NCT03759821) was a cluster-randomized 2 × 2 factorial trial plus control. Eighty village clusters were randomly assigned to one of five intervention conditions: standard of care, mothers nutrition, couples nutrition, mothers bundled nutrition and parenting, or couples bundled nutrition and parenting. Between October 2018-May 2019, 960 households were enrolled with children under 18 months of age residing with their mother and father. Community health workers (CHWs) delivered a bi-weekly 24-session hybrid peer group/home visit gender-transformative behavior change program to either mothers or couples. GE/WE outcomes were analyzed as intention-to-treat and included time use, gender attitudes, social support, couples' communication frequency and quality, decision-making power, intimate partner violence (IPV), and women's dietary diversity (WDD). Data were collected from 957 to 815 mothers and 913 and 733 fathers at baseline and endline, respectively. Engaging couples compared to mothers only significantly increased paternal and maternal gender-equitable attitudes, paternal time spent on domestic chores, and maternal decision-making power. Bundling increased maternal leisure time, decreased maternal exposure to any IPV, and increased WDD over 7 days. A combination of engaging couples and bundling was most effective for paternal gender attitudes, couples communication frequency, and WDD over 24 h and 7 days. Our findings generate novel evidence that CHWs can deliver bundled nutrition and parenting interventions to couples in low-resource community settings that advance GE/WE more than nutrition interventions targeting only women.

Big Sister, Big Brother: A Mixed Methods Study on Older Siblings’ Role in Infant and Young Child Feeding and Care in Rural Tanzania (P10-020-19)

Objectives

Nutrition interventions to improve infant and young child feeding (IYCF) and care in developing countries usually target mothers, while critical roles of other family members, particularly older siblings, are not well known. As part of the Engaging Fathers for Effective Child Nutrition and Development in Tanzania (EFFECTS) cluster-randomized trial (ClinicalTrials.gov: NCT03759821), we examined the roles of older children and adolescents in IYCF and care in rural Tanzania to develop and administer informed quantitative questionnaires on IYCF and care by older siblings.

Methods

Twelve mothers, 12 fathers, 4 grandmothers, and 4 older siblings (7–17 years of age) were purposively sampled for qualitative interviews conducted July-August 2018. Open-ended questions explored older siblings’ roles in IYCF and care, managing time for child care, and responsiveness to young children's hunger cues. Inductive and deductive approaches were used to identify themes from transcribed interviews. Findings supported development of two questionnaires on older children's roles in IYCF and care (14 questions each) that were administered to mothers and siblings in the EFFECTS baseline.

Results

Qualitative data indicate older siblings (male and female) are involved in food preparation (e.g., starchy staples), daily feeding, hygiene (e.g., washing baby after toileting) and care when the mother is unavailable due to other household activities. The EFFECTS study enrolled 960 households across 80 villages in Mara, Tanzania, and 53% of households identified at least one sibling who cares for an index child aged 0–18 months. Baseline data collection is ongoing and indicates prevalence and types of child care (e.g., feeding, playing, hygiene, responding to crying) provided by older siblings.

Conclusions

To our knowledge, this is the first mixed methods study developing instruments to investigate the role of older siblings in providing IYCF and care in a rural, developing country setting. As parents seek to meet household and livelihood needs, older siblings are often engaged in child feeding and care. Nutrition interventions should consider roles of all family members, including older children, in child feeding and care. Further research is needed to evaluate the effect of family-based interventions.

Development and Feasibility of Tablet-based 24-hour Recall for Dietary Intake and Recipe Collection Among Adults and Children in Tanzania (P10-018-19)

Objectives

In many regions of the world, little is known about food consumption, meal structures, meal patterns, and nutrient intake. Collection of these data using quantitative dietary intake is expensive and labor intensive. Thus, many programmatic and routine surveillance studies resort to simplified indicators to measure dietary quality. Based on a previous study conducted by Caswell et al. on tablet-based data collection of 24-hour dietary recall (24hr-DR), we have developed and adapted a mobile tool collecting 24hr-DR among adults and children in Tanzania.

Methods

Using the Tanzanian food composition table (FCT), the 24hr-DR was developed on an Android platform in Open Data Kit. The module provides food groups, food lists, meal list, ingredient list, quantity and amount consumed, breastfeeding frequency, and a recipe feature to collect detailed information (such as cooked and uncooked weights). Similar to the USDA Automated Multiple Pass Method, to accurately capture the dietary intake the tool contains summary features such as time in between meals and review of meals and portion size consumed in the previous day.

Results

The mobile tool is currently used to collect dietary intake (1) among 960 children 0–18 months of age enrolled in the EFFECTS trial (ClinicalTrials.gov Identifier: NCT03759821) in Mara, Tanzania, and (2) among adult families enrolled in the DECIDE study in Dar es Salaam. Field workers were first trained on paper-based methods with food models followed by training on tablet-based collection. Because the tool was tailored with the Tanzanian FCT, conversion to nutrient intake for the individual are readily linked. This enables the investigators to look at dietary intake data in real time for quality assurance and analysis. Demonstration of the tool along with dietary profiles and analysis will be compared with the literature. The tool will be made available to the public in December 2019, and can be adapted to different contexts.

Conclusions

Using mobile-based flexible platforms linked to a pre-existing FCT demystifies the “black box” processes of converting dietary intake to nutrient intake, thus reducing the time and labor needed using the traditional paper-based 24hr-DR method.
