Estimates of the Quality of Complementary Feeding Amongvietnamese Infants Aged 6-23months Varied by Howcommercial Baby Cereals Were Classified in 24-H Recalls

The World Health Organization\u27s (WHO) standardized questionnaire for assessing infant and young child feeding practices does not include commercial baby cereals (CBC), which are derived from several food groups and are fortified with micronutrients. We examined how different scenarios for classifying CBC affect estimates of the quality of complementary feeding in children ages 6−23 months in Vietnam in 2014 (n = 4811). In addition to the WHO standardized 24‐h recall questionnaire for infant and young child feeding, we asked mothers about the consumption of CBC. The five resulting scenarios were S1 – omitted CBC; S2 – CBC classified as grains; S3 – as grains and dairy; S4 – as grains, dairy and fruit/vegetables; and S5 – as grains, dairy, fruit/vegetables and any others. Including CBC resulted in 4−11 percentage points higher in the prevalence of children who were fed each of the six food groups compared with what was reported in the WHO standardized questionnaire. Minimum dietary diversity (% fed ≥ 4 out of the 7 food groups) was higher in S5 (90%) than in S1 (84%), S2 (84%), S3 (85%) and S4 (86%). Minimum acceptable diet was also higher in scenarios S5 (80%) than in S1 (74%), S2 (75%), S3 (75%) and S4 (77%). Consumption of iron‐rich foods was 94% when CBC was accounted, which was higher than the alternative scenario (89%). In summary, when CBC were included, population‐level estimates of dietary quality were higher than when CBC were omitted. Guidance is required from the WHO about how to account for the consumption of CBC when estimating the quality of complementary feeding

Infant and Young Child Feeding Practices Differ by Ethnicity of Vietnamese Mothers

Background: Limited studies have examined ethnic variation in breastfeeding and complementary feeding practices in developing countries. This study investigated ethnic variation in feeding practices in mothers with children 0–23 months old in Vietnam. Methods: We used data on 1875 women who came from the ethnic majority, Kinh (n = 989, randomly sampled from 9875 surveyed Kinh mothers, 10 % from each province) and three ethnic minorities: E De-Mnong (n = 309), Thai-Muong (n = 229) and Tay-Nung (n = 348). Ethnic minorities were compared with the Kinh group using logistic regression model. Results: Prevalence of breastfeeding initiation within an hour of birth was 69 % in Thai-Muong, but ~50 % in other ethnicities. In logistic regression, the prevalence of breastfeeding within one hour was lower in Tay-Nung (OR: 0.54; 95 % CI: 0.38, 0.77) than the majority Kinh. Prevalence of exclusive breastfeeding under 6 months was 18, 10, 17, and 33 % in Kinh, Thai-Muong, Tay-Nung, and E De-Mnong, respectively; compared to the majority Kinh, the prevalence was lower in Thai-Muong (OR: 0.42; 95 % CI: 0.25, 0.71) and higher in E De-Mnong (OR: 1.99; 95 % CI: 1.04, 3.82). Overall prevalence of bottle feeding in Thai-Muong and E De-Mnong (~20 %) was lower than in Kinh (~33 %): Thai-Muong (OR: 0.50; 95 % CI: 0.37, 0.68) and E De-Mnong (OR: 0.69; 95 % CI: 0.50, 0.95). Compared with Kinh (75 %), fewer ethnic minority children received minimum acceptable diets (33 % in Thai-Muong, 46 % in E De-Mnong, and 52 % in Tay-Nung; P \u3c 0.05). Prevalence of minimum acceptable diet (met both dietary frequency and diversity) was lower in Thai-Muong (OR: 0.23; 95 % CI: 0.11, 0.46), Tay-Nung (OR: 0.52; 95 % CI: 0.39, 0.69), and E De-Mnong (OR: 0.55; 95 % CI: 0.33, 0.89) than the majority Kinh. Conclusions: Breastfeeding practices were suboptimal and differed by ethnicity, which suggests need for tailored interventions at multiple levels to address ethnic-specific challenges and norms. Complementary feeding practices were less optimal among ethnic minorities compared to Kinh, which suggests need for broad intervention including improved food availability, accessibility, and security

Infant Formula Feeding at Birth Is Common and Inversely Associated With Subsequent Breastfeeding Behavior in Vietnam

BACKGROUND: The association between infant formula feeding at birth and subsequent feeding patterns in a low- or middle-income context is not clear. OBJECTIVE: We examined the association of infant formula feeding during the first 3 d after birth with subsequent infant formula feeding and early breastfeeding cessation in Vietnam. METHODS: In a cross-sectional survey, we interviewed 10,681 mothers with children aged 0-23 mo (mean age: 8.2 mo; 52% boys) about their feeding practices during the first 3 d after birth and on the previous day. We used stratified analysis, multiple logistic regression, propensity score-matching analysis, and structural equation modeling to minimize the limitation of the cross-sectional design and to ensure the consistency of the findings. RESULTS: Infant formula feeding during the first 3 d after birth (50%) was associated with a higher prevalence of subsequent infant formula feeding [stratified analysis: 7-28% higher (nonoverlapping 95% CIs for most comparisons); propensity score-matching analysis: 13% higher (P \u3c 0.001); multiple logistic regression: OR: 1.47 (95% CI: 1.30, 1.67)]. This practice was also associated with a higher prevalence of early breastfeeding cessation (e.g., \u3c 24 mo) [propensity score-matching analysis: 2% (P = 0.08); OR: 1.33 (95% CI: 1.12, 1.59)]. Structural equation modeling showed that infant formula feeding during the first 3 d after birth was associated with a higher prevalence of subsequent infant formula feeding (β : 0.244; P \u3c 0.001), which in turn was linked to early breastfeeding cessation (β : 0.285; P \u3c 0.001). CONCLUSIONS: Infant formula feeding during the first 3 d after birth was associated with increased subsequent infant formula feeding and the early cessation of breastfeeding, which underscores the need to make early, exclusive breastfeeding normative and to create environments that support it

Community Support Model on Breastfeeding and Complementary Feeding Practices in Remote Areas in Vietnam: Implementation, Cost, and Effectiveness

Background Poor access to healthcare facilities and consequently nutrition counseling services hinders the uptake of recommended infant and young child feeding (IYCF) practices. To address these barriers and improve IYCF practices, Alive & Thrive (A&T) initiated community support groups in remote villages across nine provinces in Vietnam. Objective This study examines the effectiveness of the support group model and related project costs for reaching underserved areas to improve IYCF practices. Methods To evaluate the model’s implementation and project costs, we reviewed implementation guidelines, expenditure and coverage reports, monitoring data, and budgets for the nine provinces. To evaluate the model’s effectiveness, we used a 3-stage sampling method to conduct a cross-sectional survey from April to May 2014 in three provinces entailing interviewing mothers of children aged 0–23 months in communes with (intervention; n = 551) and without support groups (comparison; n = 559). Findings Coverage: From November 2011 to November 2014, in partnership with the government, A&T supported training for 1513 facilitators and the establishing 801 IYCF support groups in 267 villages across nine provinces. During this period, facilitators provided ~ 166,000 meeting/support contacts with ~ 33,000 pregnant women and mothers with children aged 0–23 months in intervention villages. Costs: The average project costs for supporting the meetings, compensating village collaborators, and providing supportive supervision through staff in commune health stations were USD 5 per client and USD 1 per contact. After adding expenditures for training, supportive supervision, and additional administrative costs at central and provincial levels, the average project cost was USD 15 per client and USD 3 per contact. Effectiveness: Survey participants in intervention and comparison communes had similar maternal, child, and household characteristics. Multiple logistic regression models showed that living in intervention communes was associated with higher odds of early initiation of breastfeeding (OR: 1.7; 95% CI: 1.1, 2.7), exclusive breastfeeding from 0 to 5 months (OR: 12.5; 95% CI: 6.7, 23.4), no bottle feeding (OR: 2.69; 95% CI: 1.82, 3.99), and minimum acceptable diet (OR: 1.51; 95% CI: 0.98, 2.33) compared to those living in comparison communes. Conclusion The IYCF support group model was effective in reaching populations residing in remote areas and likely contributed to improved IYCF practices. The study suggests that the model could be scaled up to promote equity in breastfeeding support

Exposure to Mass Media and Interpersonal Counseling Has Additive Effects on Exclusive Breastfeeding and Its Psychosocial Determinants Among Vietnamese Mothers

The pathways through which behavior change interventions impact breastfeeding practices have not been well studied. This study aimed to examine: (1) the effects of exposure to mass media and interpersonal counseling on exclusive breastfeeding (EBF) and hypothesized psychosocial determinants (i.e. knowledge, intention, beliefs, social norms, and self-efficacy); and (2) the pathways through which exposure to mass media and interpersonal counseling are associated with EBF. We used survey data from mothers with children\u3c 2 year (n = 2045) from the 2013 process evaluation of Alive & Thrive’s program in Viet Nam. Multiple linear regression analyses and structural equation modeling were used to estimate effects. Exposure to mass media only, interpersonal counseling only, both or neither was 51%, 5%, 19% and 25%, respectively. Exposure to both mass media and interpersonal counseling had additive effects on EBF as well as on related psychosocial factors, compared with no exposure. For example, EBF prevalence was 26.1 percentage points (pp) higher in the group that received interpersonal counseling only, 3.9 pp higher in the mass media group and 31.8 pp higher in the group that received both interventions. As hypothesized, more than 90% of the total effect of the two interventions on EBF was explained by the psychosocial factors measured. Our findings suggest that combining different behavior change interventions leads to greater changes in psychosocial factors, which in turn positively affects breastfeeding behaviors

Social Franchising and a Nationwide Mass Media Campaign Increased the Prevalence of Adequate Complementary Feeding in Vietnam: A Cluster-Randomized Program Evaluation

Rigorous evaluations of health system-based interventions in large-scale programs to improve complementary feeding (CF) practices are limited. Alive & Thrive applied principles of social franchising within the government health system in Vietnam to improve the quality of interpersonal counseling (IPC) for infant and young child feeding combined with a national mass media (MM) campaign and community mobilization (CM). We evaluated the impact of enhanced IPC + MM + CM (intensive) compared with standard IPC + less-intensive MM and CM (nonintensive) on CF practices and anthropometric indicators. A cluster-randomized, nonblinded evaluation design with cross-sectional surveys ( = ∼500 children aged 6-23.9 mo and ∼1000 children aged 24-59.9 mo/group) implemented at baseline (2010) and endline (2014) was used. Difference-in-difference estimates (DDEs) of impact were calculated for intent-to-treat (ITT) analyses and modified per-protocol analyses (MPAs; mothers who attended the social franchising at least once: 62%). Groups were similar at baseline. In ITT analyses, there were no significant differences between groups in changes in CF practices over time. In the MPAs, greater improvements in the intensive than in the nonintensive group were seen for minimum dietary diversity [DDE: 6.4 percentage points (pps); \u3c 0.05] and minimum acceptable diet (8.0 pps; \u3c 0.05). Significant stunting declines occurred in both intensive (7.1 pps) and nonintensive (5.4 pps) groups among children aged 24-59.9 mo, with no differential decline. When combined with MM and CM, an at-scale social franchising approach to improve IPC, delivered through the existing health care system, significantly improved CF practices, but not child growth, among mothers who used counseling services at least once. A greater impact may be achieved with strategies designed to increase service utilization. This trial was registered at clinicaltrials.gov as NCT01676623

Supply- and Demand-Side Factors Influencing Utilization of Infant and Young Child Feeding Counselling Services in Viet Nam

Adequate utilization of services is critical to maximize the impact of counselling on infant and young child feeding (IYCF), but little is known about factors affecting utilization. Our study examined supply- and demand-side factors associated with the utilization of IYCF counselling services in Viet Nam. We used survey data from mothers with children \u3c2y \u3e(n = 1,008) and health staff (n = 60) from the evaluation of a program that embedded IYCF counseling into the existing government health system. The frequency of never users, one-time users, repeat users, and achievers of the recommended minimum number of visits at health facilities were 45.1%, 13.0%, 28.4% and 13.5%, respectively. Poisson regression showed that demand-generation strategies, especially invitation cards, were the key factors determining one-time use (Prevalence ratio, PR 3.0, 95% CI: 2.2–4.2), repeated use (PR 3.2, 95% CI: 2.4–4.2), and achievement of minimum visits (PR 5.5, 95% CI: 3.6–8.4). Higher maternal education was associated with higher utilization both for one-time and repeated use. Being a farmer, belonging to an ethnic minority, and having a wasted child were associated with greater likelihood of achieving the minimum recommended number of visits, whereas child stunting or illness were not. Distance to health center was a barrier to repeated visits. Among supply-side factors, good counselling skills (PR: 1.3–1.8) was the most important factor associated with any service use, whereas longer employment duration and greater work pressure of health center staff were associated with lower utilization. Population attributable risk estimations showed that an additional 25% of the population would have achieved the minimum number of visits if exposed to three demand-generation strategies, and further increased to 49% if the health staff had good counseling skills and low work pressure. Our study provides evidence that demand-generation strategies are essential to increase utilization of facility-based IYCF counselling services in Viet Nam, and may be relevant for increasing and sustaining use of nutrition services in similar contexts

Impacts on Breastfeeding Practices of At Scale Strategies That Combine Intensive Interpersonal Counseling, Mass Media, and Community Mobilization: Results of Cluster Randomized Program Evaluations in Bangladesh and Viet Nam

Background Despite recommendations supporting optimal breastfeeding, the number of women practicing exclusive breastfeeding (EBF) remains low, and few interventions have demonstrated implementation and impact at scale. Alive & Thrive was implemented over a period of 6 y (2009–2014) and aimed to improve breastfeeding practices through intensified interpersonal counseling (IPC), mass media (MM), and community mobilization (CM) intervention components delivered at scale in the context of policy advocacy (PA) in Bangladesh and Viet Nam. In Bangladesh, IPC was delivered through a large non-governmental health program; in Viet Nam, it was integrated into government health facilities. This study evaluated the population-level impact of intensified IPC, MM, CM, and PA (intensive) compared to standard nutrition counseling and less intensive MM, CM, and PA (non-intensive) on breastfeeding practices in these two countries. Methods and Findings A cluster-randomized evaluation design was employed in each country. For the evaluation sample, 20 sub-districts in Bangladesh and 40 communes in Viet Nam were randomized to either the intensive or the non-intensive group. Cross-sectional surveys (n ~ 500 children 0–5.9 mo old per group per country) were implemented at baseline (June 7–August 29, 2010, in Viet Nam; April 28–June 26, 2010, in Bangladesh) and endline (June 16–August 30, 2014, in Viet Nam; April 20–June 23, 2014, in Bangladesh). Difference-in-differences estimates (DDEs) of impact were calculated, adjusting for clustering. In Bangladesh, improvements were significantly greater in the intensive compared to the non-intensive group for the proportion of women who reported practicing EBF in the previous 24 h (DDE 36.2 percentage points [pp], 95% CI 21.0–51.5, p \u3c 0.001; prevalence in intensive group rose from 48.5% to 87.6%) and engaging in early initiation of breastfeeding (EIBF) (16.7 pp, 95% CI 2.8–30.6, p = 0.021; 63.7% to 94.2%). In Viet Nam, EBF increases were greater in the intensive group (27.9 pp, 95% CI 17.7–38.1, p \u3c 0.001; 18.9% to 57.8%); EIBF declined (60.0% to 53.2%) in the intensive group, but less than in the non-intensive group (57.4% to 40.6%; DDE 10.0 pp, 95% CI −1.3 to 21.4, p = 0.072). Our impact estimates may underestimate the full potential of such a multipronged intervention because the evaluation lacked a “pure control” area with no MM or national/provincial PA. Conclusions At-scale interventions combining intensive IPC with MM, CM, and PA had greater positive impacts on breastfeeding practices in Bangladesh and Viet Nam than standard counseling with less intensive MM, CM, and PA. To our knowledge, this study is the first to document implementation and impacts of breastfeeding promotion at scale using rigorous evaluation designs. Strategies to design and deliver similar programs could improve breastfeeding practices in other contexts
