Unsafe Infant Feeding Practice and Associated Factors Among HIV Positive Mothers Attending PMTCT in Ethiopia: A Cross-Sectional Study

Introduction

Infant feeding practices can have an impact on the health of infants born to HIV-positive mothers. Breastfeeding has significant health advantages for newborns even while it increases the risk of HIV transmission from an HIV-positive mother to her child. One-third to half of child HIV infections in African settings may be linked to breastfeeding. This study was intended to investigate the level of unsafe infant feeding practice and associated factors among HIV positive mothers attending PMTCT at selected governmental hospitals in Afar regional state, Ethiopia, 2022.

Methods

A cross-sectional study was done among 423 HIV positive mothers from February 15 to March 15, 2022 in Afar regional state at selected PMTCT providing governmental hospitals. The proportional allocation was done for samples to be taken from Asayta, Dupti and Mohammed Akle hospitals. A systematic sampling technique was performed to select the study participants. Epidata version 3.1 was used for data entry, and SPSS software version 23 was used for statistical analysis.

Results

The majority, 296 (70.0%), of mothers with HIV-positive were aged between 25 and 34 years. The level of unsafe infant feeding practice among HIV-positive mothers was 153 (36.2%). About 270 (63.8%) mothers exclusively breastfed their infants. In multivariable logistic regression analysis, PNC follow-up (AOR=1.814, 95% CI: (1.127, 2.919)), ART follow-up (AOR=1.987, 95% CI: (1.128, 3.501)), and HIV disclosure status (AOR=2.324, 95% CI: (1.470, 3.673)) were significantly associated with unsafe infant feeding practice among HIV-positive mothers.

Conclusion

The level of unsafe infant feeding practice among HIV-positive mothers was high. PNC follow-up, ART follow-up, and HIV disclosure status were significantly associated with unsafe infant feeding practice among HIV-positive mothers. Comprehensive health educations need to be provided for HIV-positive mothers to reduce this problem.

Prevalence of Infant and Young Child Feeding Practices and Differences in Estimates of Minimum Dietary Diversity Using 2008 and 2021 Definitions: Evidence from Bangladesh

Background

Infant and young child feeding (IYCF) practices directly impact the health of <2-y-old children. Minimum dietary diversity (MDD) is an IYCF indicator to assess feeding practices of children aged 6-23 mo. The definition of MDD has recently been updated by the WHO and UNICEF, substituting "≥4 out of 7 food groups" (MDD-7FG) with "≥5 out of 8 food groups" (MDD-8FG).

Objectives

The goals of this study were to estimate the prevalence of IYCF indicators and identify the implications of the change in the prevalence of MDD at the national and regional levels of Bangladesh.

Methods

This study used data from the National Food Security and Nutrition Surveillance 2018-2019 round. A total of 1992 children aged 0-23 mo were included in this analysis. IYCF indicators and MDD were calculated according to the WHO-UNICEF guidelines. The difference between the prevalence of MDD-7FG and MDD-8FG is presented as percentage points.

Results

The prevalence of early initiation of breastfeeding was 43.8%, and exclusive breastfeeding was 56.2%. Approximately 55% of children maintained MDD (MDD-7FG), 48% received minimum meal frequency, and 28% received a minimum acceptable diet. Compared with MDD-7FG, the prevalence of MDD-8FG was lower among 6-23-mo-old children. The difference between MDD prevalence (MDD-8FG vs. MDD-7FG) was high for boys (44.0% vs. 53.2%), children aged 12-23 mo (53.4% vs. 63.4%), in urban areas (30.2% vs. 42.4%), in the Dhaka administrative division (42.0% vs. 56.3%), among uneducated mothers (37.1% vs. 47.1%), in households with ≤4 members (44.3% vs. 55%), and for middle-class households (40.3% vs. 57.6%).

Conclusions

The new method led to a decrease in the prevalence of MDD in Bangladesh. As the country prepares to implement the new indicator, it is critical to disseminate the new knowledge and its positive implication for improved child feeding and nutrition.

Fluoridated Water Modifies the Effect of Breastfeeding on Dental Caries

Breastfeeding is important for health and development. Yet, the interaction between breastfeeding duration and usage of fluoridated water on caries experience has not been investigated. This study examined exposure to fluoridation as an effect modifier of the association between breastfeeding duration and caries. The 2012 to 2014 national population-based study of Australian children involved parental questionnaires and oral epidemiological assessment. Children were grouped by parent-reported breastfeeding duration into minimal (none or <1 mo), breastfed for 1 to <6 mo, breastfed for 6 to 24 mo, and sustained (>24 mo). Residential history and main water source used for the first 2 y of life were collected to group children into exposed (WF) and nonexposed (NF) to fluoridation. Socioeconomic status, infant formula feeding, and sugar-sweetened beverage (SSB) consumption data were collected. The prevalence and severity of caries in children aged 5 to 6 y were primary outcomes. Multivariable regression models with robust error estimation were generated to compute prevalence ratios (PRs) and mean ratios (MRs) for 3 breastfeeding groups against the reference (breastfed for 6-24 mo). Of the 5- to 6-y-old children, 2,721 were in the WF and 1,737 were in the NF groups. The groups had comparable distributions of socioeconomic factors, infant formula feeding, and SSB consumption. There were U-shape distributions of caries experience among breastfeeding groups, being more pronounced among NF children. Among NF children, the minimal and sustained breastfeeding groups had significantly higher PR (1.4 [1.1-1.9] and 1.8 [1.4-2.4]) and MR (2.1 [1.4-3.3] and 2.4 [1.4-4.1]) than the reference group. However, among the WF children, this association between breastfeeding duration and caries attenuated after adjustment for other factors. The study contributes evidence of a nonlinear (U-shape) association between breastfeeding duration and dental caries. Early life exposure to fluoridated drinking water attenuated the potential cariogenic effect of both lack of and sustained breastfeeding.

Following the World Health Organization's Recommendation of Exclusive Breastfeeding to 6 Months of Age Does Not Impact the Growth of Rural Gambian Infants

BACKGROUND

The WHO recommends exclusive breastfeeding (EBF) for the first 6 mo of life.

OBJECTIVE

The objective of this study was to assess the benefit of EBF to age 6 mo on growth in a large sample of rural Gambian infants at high risk of undernutrition.

METHODS

Infants with growth monitoring from birth to 2 y of age (n = 756) from the ENID (Early Nutrition and Immune Development) trial were categorized as exclusively breastfed if only breast milk and no other liquids or foods were given. EBF status was entered into confounder-adjusted multilevel models to test associations with growth trajectories by using >11,000 weight-for-age (WAZ), length-for-age (LAZ), and weight-for-length (WLZ) z score observations.

RESULTS

Thirty-two percent of infants were exclusively breastfed to age 6 mo. The mean age of discontinuation of EBF was 5.2 mo, and growth faltering started at ∼3.5 mo of age. Some evidence for a difference in WAZ and WHZ was found between infants who were exclusively breastfed to age 6 mo (EBF-6) and those who were not (nEBF-6), at 6 and 12 mo of age, with EBF-6 children having a higher mean z score. The differences in z scores between the 2 groups were small in magnitude (at 6 mo of age: 0.147 WAZ; 95% CI: -0.001, 0.293 WAZ; 0.189 WHZ; 95% CI: 0.038, 0.341 WHZ). No evidence for a difference between EBF-6 and nEBF-6 infants was observed for LAZ at any time point (6, 12, and 24 mo of age). Furthermore, a higher mean WLZ at 3 mo of age was associated with a subsequent higher mean age at discontinuation of EBF, which implied reverse causality in this setting (coefficient: 0.060; 95% CI: 0.008, 0.120).

CONCLUSION

This study suggests that EBF to age 6 mo has limited benefit to the growth of rural Gambian infants. This trial was registered at http://www.isrctn.com as ISRCTN49285450.
