Predictors of micronutrient powder (MNP) knowledge, coverage, and consumption during the scale-up of an integrated infant and young child feeding (IYCF-MNP) programme in Nepal.

Large-scale programmes using micronutrient powders (MNPs) may not achieve maximum impact due to limited/inappropriate MNP coverage, consumption, and use. We identify predictors of MNP coverage, maternal knowledge of appropriate use, and child MNP consumption in Nepal. A cross-sectional survey was conducted in 2,578 mother-child pairs representative of children 6-23 months in two districts that were part of the post-pilot, scale-up of an integrated infant and young child feeding-MNP (IYCF-MNP) programme. Children aged 6-23 months were expected to receive 60 MNP sachets every 6 months from a female community health volunteer (FCHV) or health centre. Outcomes of interest were MNP coverage (ever received), maternal knowledge of appropriate use (correct response to seven questions), repeat coverage (receipt ≥ twice; among children 12-23 months who had received MNP at least once, n = 1342), and high intake (child consumed ≥75% of last distribution, excluding those with recent receipt/insufficient time to use 75% at recommended one-sachet-per-day dose, n = 1422). Multivariable log-binomial regression models were used to identify predictors of the four outcomes. Coverage, knowledge of appropriate use, and repeat coverage were 61.3%, 33.5%, and 45.9%, respectively. Among MNP receivers, 97.9% consumed MNP at least once and 38.9% of eligible children consumed ≥75% of last distribution. FCHV IYCF-MNP counselling was positively associated with knowledge, coverage, repeat coverage, and high intake; health worker counselling with knowledge and coverage indicators; and radio messages with coverage indicators only. FCHV counselling had the strongest association with knowledge, coverage, and high intake. Community-based counselling may play a vital role in improving coverage and intake in MNP programmes.

Changes in growth, anaemia, and iron deficiency among children aged 6-23 months in two districts in Nepal that were part of the post-pilot scale-up of an integrated infant and young child feeding and micronutrient powder intervention.

There is limited research on integrated infant and young child feeding (IYCF) and micronutrient powders (MNPs) programmes operating at scale, despite widespread implementation. This study uses cross-sectional baseline (n = 2,542) and endline (n = 2,578) surveys representative of children 6-23 months in two districts in Nepal that were part of a post-pilot scale-up of a IYCF-MNP programme. Multivariable log-binomial regression models were used to estimate prevalence ratios (PRs) for stunting (length-for-age z-score <-2), wasting (weight-for-length z-score <-2), underweight (weight-for-age z-score <-2), anaemia (altitude-adjusted haemoglobin <110 µg/L), moderate or severe anaemia (altitude-adjusted haemoglobin <100 g/L), iron deficiency (inflammation-adjusted ferritin <12 µg/L), and iron deficiency anaemia (iron deficiency + anaemia [IDA]) at endline versus baseline and also to compare children in the endline survey based on frequency of mothers' interactions with female community health volunteers (FCHVs; >1× per month or monthly vs. <1× per month) and MNP coverage (1 or ≥2 distributions vs. none among children 12-23 months). Endline children were significantly less likely to be stunted than baseline children in both districts (multivariable-adjusted PR [95% CI]: 0.77 [0.69, 0.85], P < 0.001 and 0.82 [0.75, 0.91], P < 0.001 in Kapilvastu and Achham, respectively); however, only Achham had significantly lower prevalences of underweight, moderate/severe anaemia, iron deficiency, and IDA at endline. At endline, 53.5% and 71.4% of children had tried MNP in Kapilvastu and Achham districts, respectively, consuming an average of 24 sachets from the last distribution. Frequent maternal-FCHV interactions were associated with a reduced risk of stunting and underweight at endline, whereas repeat MNP coverage was associated with reduced risk of anaemia and IDA. Future research using experimental designs should verify the potential of integrated IYCF-MNP programmes to improve children's nutritional status.

Infant and Young Child Feeding (IYCF) Practices Improved in 2 Districts in Nepal during the Scale-Up of an Integrated IYCF and Micronutrient Powder Program.

BACKGROUND: Three-quarters of the ≥50 programs that use micronutrient powders (MNPs) integrate MNPs into infant and young child feeding (IYCF) programs, with limited research on impacts on IYCF practices. OBJECTIVE: This study assessed changes in IYCF practices in 2 districts in Nepal that were part of a post-pilot scale-up of an integrated IYCF-MNP program. METHODS: This analysis used cross-sectional surveys (n = 2543 and 2578 for baseline and endline) representative of children aged 6-23 mo and their mothers in 2 districts where an IYCF program added MNP distributions through female community health volunteers (FCHVs) and health workers (HWs). Multivariable log-binomial models estimated prevalence ratios comparing reported IYCF at endline with baseline and at endline on the basis of exposure to different sources of IYCF information. Mothers who received FCHV-IYCF counseling with infrequent (≤1 time/mo) and frequent (>1 time/mo) interactions were compared with mothers who never received FCHV-IYCF counseling. The receipt of HW-IYCF counseling and receipt of MNPs from an FCHV (both yes or no) were also compared. RESULTS: The prevalence of minimum dietary diversity (MDD) and minimum acceptable diet (MAD) was significantly higher at endline than at baseline. In analyses from endline, compared with mothers who never received FCHV counseling, only mothers in the frequent FCHV-IYCF counseling group were more likely to report feeding the minimum meal frequency (MMF) and MAD, with no difference for the infrequent FCHV-IYCF counseling group in these indicators. HW-IYCF counseling was not associated with these indicators. Mothers who received MNPs from their FCHV were more likely to report initiating solid foods at 6 mo and feeding the child the MDD, MMF, and MAD compared with mothers who did not, adjusting for HW- and FCHV-IYCF counseling and demographic covariates. CONCLUSIONS: Incorporating MNPs into the Nepal IYCF program did not harm IYCF and may have contributed to improvements in select practices. Research that uses experimental designs should verify whether integrated IYCF-MNP programs can improve IYCF practices.

Trends and predictors of appropriate complementary feeding practices in Nepal: An analysis of national household survey data collected between 2001 and 2014.

There is evidence that suboptimal complementary feeding contributes to poor child growth. However, little is known about time trends and determinants of complementary feeding in Nepal, where the prevalence of child undernutrition remains unacceptably high. The objective of the study was to examine the trends and predictors of suboptimal complementary feeding in Nepali children aged 6-23 months using nationally representative data collected from 2001 to 2014. Data from the 2001, 2006, and 2011 Nepal Demographic and Health Surveys and the 2014 Multiple Indicator Cluster Survey were used to estimate the prevalence, trends and predictors of four WHO-UNICEF complementary feeding indicators: timely introduction of complementary foods (INTRO), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD). We used multilevel logistic regression models to identify independent factors associated with these indicators at the individual, household and community levels. In 2014, the weighted proportion of children meeting INTRO, MMF, MDD, and MAD criteria were 72%, 82%, 36% and 35%, respectively, with modest average annual rate of increase ranging from 1% to 2%. Increasing child age, maternal education, antenatal visits, and community-level access to health care services independently predicted increasing odds of achieving MMF, MDD, and MAD. Practices also varied by ecological zone and sociocultural group. Complementary feeding practices in Nepal have improved slowly in the past 15 years. Inequities in the risk of inappropriate complementary feeding are evident, calling for programme design and implementation to address poor feeding and malnutrition among the most vulnerable Nepali children.
