Comparison of methods to assess consumption of micronutrient powders among young children in Nepal
Ng'eno BN , Perrine CG , Subedi GR , Mebrahtu S , Dahal P , Jefferds MED . Food Nutr Bull 2017 38 (3) 441-446 BACKGROUND: Assessing micronutrient powder (MNP) consumption is the key for monitoring program performance; no gold standard exists for assessing consumption in nutrition programs. OBJECTIVE: To compare estimates of MNP consumption assessed by maternal report versus observed unopened MNP sachets in the household. METHODS: Cross-sectional household surveys of children aged 6 to 23 months were conducted to assess an MNP project in Nepal; eligible children received 60 sachets per distribution. Mothers reported the number of sachets consumed and showed unused sachets. Directly observed difference (DOD) of MNP consumption was calculated by subtracting the number of observed unopened sachets from 60. Spearman correlation coefficient, categories of MNP consumption, and end digit preference were assessed. RESULTS: A total of 205 mothers did not show remaining unopened sachets despite reporting that all were not consumed. For the remaining 605 children, median consumption was 60.0 sachets by DOD and maternal report; the correlation coefficient was 0.91. With consumption grouped into categories of 0 to 14, 15 to 29, 30 to 44, and 45 to 60 sachets, the percent categorized into the same groupings by DOD and maternal report was 100%, 80.6%, 80.7%, and 91.2%, respectively. Excluding those who consumed 60 sachets, 16.9% and 8.0% by report and 14.2% and 6.1% DOD, ended with 0 and 5, respectively. CONCLUSION: Had the observation of unused sachets been used alone to assess MNP consumption, 205 children would not have been assessed. Estimates of MNP consumption by DOD and maternal report were similar in this population with high intake adherence. |
High prevalence of vitamin B12 deficiency and no folate deficiency in young children in Nepal
Ng'eno BN , Perrine CG , Whitehead RD , Subedi GR , Mebrahtu S , Dahal P , Jefferds ME . Nutrients 2017 9 (1) Many children in low- and middle-income countries may have inadequate intake of vitamin B12 and folate; data confirming these inadequacies are limited. We used biochemical, demographic, behavioral and anthropometric data to describe the folate and vitamin B12 concentrations among six- to 23-month-old Nepalese children. Vitamin B12 (serum B12 < 150 pmol/L) and folate deficiencies (red blood cell (RBC) folate < 226.5 nmol/L) were assessed. We used logistic regression to identify predictors of vitamin B12 deficiency. The vitamin B12 geometric mean was 186 pmol/L; 30.2% of children were deficient. The mean RBC folate concentration was 13,612 nmol/L; there was no deficiency. Factors associated with vitamin B12 deficiency included: (a) age six to 11 months (adjusted odds ratio (aOR) 1.51; 95% confidence interval (CI): 1.18, 1.92) or 12-17 months (aOR 1.38; 95% CI: 1.10, 1.72) compared to 18-23 months; (b) being stunted (aOR 1.24; 95% CI: 1.03, 1.50) compared to not being stunted; (c) and not eating animal-source foods (aOR 1.85; 95% CI: 1.42, 2.41) compared to eating animal-source foods the previous day. There was a high prevalence of vitamin B12 deficiency, but no folate deficiency. Improving early feeding practices, including the consumption of rich sources of vitamin B12, such as animal-source foods and fortified foods, may help decrease deficiency. |
Micronutrient powder use and infant and young child feeding practices in an integrated program
Mirkovic KR , Perrine CG , Subedi GR , Mebrahtu S , Dahal P , Jefferds ME . Asia Pac J Clin Nutr 2016 25 (2) 350-5 Integrated infant and young child feeding (IYCF)/micronutrient powder (MNP) programs are increasingly used to address poor IYCF practices and micronutrient deficiencies in low-income settings; however, little is known about how MNP use may affect IYCF practices. We describe how MNP use was associated with IYCF practices in a pilot program in select districts of Nepal where free MNP for children 6-23 months were added to an existing IYCF platform. Representative cross-sectional surveys were conducted in pilot districts with mothers of eligible children at 3 months (plains ecozone, n=1054) or 15 months (hill ecozone, rural only, n=654) after implementation of an integrated MNP/IYCF program. We used logistic regression to assess how IYCF practices varied by MNP use (none, 1-30, 30-60 sachets). At both time points, consuming 30-60 MNP sachets vs. none was associated with achieving minimum dietary diversity and minimum acceptable diet. In the 3 month survey consuming 30- 60 MNP sachets vs none was also associated with achieving minimum meal frequency and continued breastfeeding at 2 years. In this setting, addition of MNP to an existing platform of IYCF messaging did not appear detrimental to IYCF practices.; Publisher: Abstract available from the publisher.; chi |
Predictors of micronutrient powder intake adherence in a pilot programme in Nepal
Mirkovic KR , Perrine CG , Subedi GR , Mebrahtu S , Dahal P , Staatz C , Jefferds ME . Public Health Nutr 2015 19 (10) 1-9 OBJECTIVE: Poor adherence to recommended intake protocols is common and a top challenge for micronutrient powder (MNP) programmes globally. Identifying modifiable predictors of intake adherence could inform the design and implementation of MNP projects. DESIGN: We assessed high MNP intake adherence among children who had received MNP ≥2 months ago and consumed ≥1 sachet (n 771). High MNP intake adherence was defined as maternal report of child intake ≥45 sachets. We used logistic regression to assess demographic, intervention components and perception-of-use factors associated with high MNP intake. SETTING: Four districts of Nepal piloting an integrated infant and young child feeding and MNP project. SUBJECTS: Children aged 6-23 months were eligible to receive sixty MNP sachets every 6 months with suggested intake of one sachet daily for 60 d. Cross-sectional surveys representative of children aged 6-23 months were conducted. RESULTS: Receiving a reminder card was associated with increased odds for high intake (OR=2.18, 95 % CI 1.14, 4.18); exposure to other programme components was not associated with high intake. Mothers perceiving ≥1 positive effects in their child after MNP use was also associated with high intake (OR=6.55, 95 % CI 4.29, 10.01). Perceiving negative affects was not associated; however, the child not liking the food with MNP was associated with lower odds of high intake (OR=0.12, 95 % CI 0.08, 0.20). CONCLUSIONS: Behaviour change intervention strategies tailored to address these modifiable predictors could potentially increase MNP intake adherence. |
Predictors of micronutrient powder sachet coverage in Nepal
Jefferds ME , Mirkovic KR , Subedi GR , Mebrahtu S , Dahal P , Perrine CG . Matern Child Nutr 2015 11 Suppl 4 77-89 Many countries implement micronutrient powder (MNP) programmes to improve the nutritional status of young children. Little is known about the predictors of MNP coverage for different delivery models. We describe MNP coverage of an infant and young child feeding and MNP intervention for children aged 6-23 months comparing two delivery models piloted in rural Nepal: distributing MNPs either by female community health volunteers (FCHVs) or at health facilities (HFs). Cross-sectional household cluster surveys were conducted in four pilot districts among mothers of children 6-23 months after starting MNP distribution. FCHVs in each cluster were also surveyed. We used logistic regression to describe predictors of initial coverage (obtaining a batch of 60 MNP sachets) at 3 months and repeat coverage (≥2 times coverage among eligible children) at 15 months after project launch. At 15 months, initial and repeat coverage were higher in the FCHV model, although no differences were observed at 3 months. Attending an FCHV-led mothers' group meeting where MNP was discussed increased odds of any coverage in both models at 3 months and of repeat coverage in the HF model at 15 months. Perceiving ≥1 positive effects in the child increased odds of repeat coverage in both delivery models. A greater portion of FCHV volunteers from the FCHV model vs. the HF model reported increased burden at 3 and 15 months (not statistically significant). Designing MNP programmes that maximise coverage without overburdening the system can be challenging and more than one delivery model may be needed. |
