Predictors of breast milk substitute feeding among newborns in delivery facilities in urban Cambodia and Nepal

Factors Associated With Prelacteal Feeding of Commercial Milk Formula: An Analysis of Cohort Data From the BADUTA Study in Indonesia

Introducing commercial milk formula (CMF) as prelacteal feeds can disturb exclusive breastfeeding and shorten breastfeeding duration. However, the prelacteal feeding of CMF has been growing alongside its increasing sales in Indonesia. This study examined predictors of the CMF feeding in the Malang and Sidoarjo districts of Indonesia. This analysis used post-delivery data collected from 676 mothers in a cohort evaluation of a cluster randomised controlled trial (Baduta study). Multivariate random effects logistic models were employed to assess factors associated with the CMF feeding. A total of 467 (69.1%) respondents reported giving CMF to their infants during the first 3 days after delivery. Mothers with low breastfeeding self-efficacy (BFSE) were at a higher risk of providing CMF within 3 days of birth compared to those with medium or high BFSE (adjusted odds ratio (aOR) 8.12; 95% confidence interval (CI) (4.26-15.48). Receiving explanations to solve breastfeeding problems from health professionals (aOR: 1.87; 97% CI: 1.12-3.11) and primipara parity (aOR: 1.71; 95% CI: 1.12-3.04) were positively associated with the CMF feeding. Early initiation of breastfeeding (EIBF) was protective against CMF feeding (aOR: 0.40; 95% CI: 0.22-0.58). There was an interaction between EIBF and BFSE. EIBF was protective among mothers with high or medium BFSE, but had no effect among those with low BFSE. CMF feeding was prevalent in Indonesia. Future strategies should focus on improving health-staff capacity to strengthen BFSE during pregnancy and provide adequate counselling for mothers with breastfeeding problems.

The characteristics of formula milk marketing on health system: a qualitative study from Beijing and Jinan in China

BACKGROUND

Breastmilk is widely regarded as the healthiest choice for both infants and mothers due to its numerous advantages over formula, such as higher concentrations of essential nutrients and antibodies, easier digestion, and superior taste. The World Health Organization International Code of Marketing of Breast-milk Substitutes was adopted over 40 years ago to mitigate the effects of infant formula marketing on a woman's decision to breastfeed. Yet, the commercial formula milk industry has continued to market their products aggressively and through an increasing variety of social media channels. This study examines the impact of formula milk marketing on specific components of the health system to understand how systems that are built to support and sustain breastfeeding may have been captured and repurposed by industry practices.

METHODS

As part of A Multi-country Study of Early Infant Feeding Decisions, this qualitative study was conducted in two representative cities in China, Beijing and Jinan, in 2020. The participants were recruited through convenience sampling and snowballing sampling methods. Data were collected through 40 in-depth interviews and 10 focus group discussions with health professionals, pregnant women, and formula milk marketing executives. A thematic analytical method was used to analyze the main themes and sub-themes that detail the characteristics of formula milk marketing and its impact on the health system in China.

RESULTS

Our results identified the most common practices used by the formula milk industry to reach health workers as well as mothers and their families through health systems. Such practices include (1) provider/facility-based marketing to sponsor academic activities (e.g., seminars, conferences, and research projects) and promote specialized infant formula that targets health care providers and facilities, which influence the health consultations and recommendations provided by health professionals to mothers and families; and (2) receiver-based marketing that targets Chinese women and increases marketing exposure through lectures provided by maternity schools at health facilities during the antenatal period and health promotion activities organized by formula milk companies outside of facilities during the postnatal care period.

CONCLUSIONS

Formula milk marketing aims to influence the practices and services within the health system in China, both directly through health professionals and facilities, and also indirectly by targeting mothers. These marketing strategies have impacted the perceptions of providers on formula milk, and strategies targeting consumers have aimed to further influence and undermine mothers' intentions to continue breastfeeding. Stricter regulation of industry marketing practices is needed to create a supportive environment for mothers to breastfeed.

Introduction of Breast Milk Substitutes During the First 3 Days of Life: Results of the Mexican National Survey of Demographic Dynamics, 2018

Background: The introduction of foods or fluids other than breast milk in the first few days after birth interferes with the establishment of breastfeeding. This study aimed to investigate the association of formula introduction during the first 3 days of life with maternal sociodemographic characteristics, hospital practices, and breastfeeding duration. Materials and Methods: Information from the National Survey of Demographic Dynamics, 2018, which includes 17,686 mother-baby pairs was analyzed. Mother-baby pairs were classified into categories according to breastfeeding duration: <5 months and ≥5 months. Statistical methods and a machine learning algorithm (Bayesian network, BN) were used to analyze the data. Results: In general, 3,720 (21%) mothers reported introducing formula during the first 3 days of life. A lower education level, lower sociodemographic stratum, living in a rural area, and considering oneself indigenous were factors associated with not introducing formula during the first 3 days of life. A total of 5,168 (29.2%) mother-baby pairs practiced breastfeeding for <5 months, and 12,518 (70.8%) for ≥5 months. Almost twice as many mothers who practiced breastfeeding for <5 months introduced formula during the first 3 days of life (31.7%) compared with those who practiced breastfeeding for ≥5 months (16.6%). The BN model can sufficiently predict cases with a breastfeeding duration ≥5 months (precision-recall curve area = 0.792). Discussion: Introducing formula during the first 3 days of life was associated with a shorter breastfeeding duration. BN analysis showed a probabilistic dependency between the type of delivery and variables associated with the establishment of breastfeeding.

Countries' experiences scaling up national breastfeeding, protection, promotion and support programmes: Comparative case studies analysis

Scaling up effective interventions, policies and programmes can improve breastfeeding (BF) outcomes. Furthermore, considerable interest exists in learning from relatively recent successful efforts that can inform further scaling up, with appropriate adaptations, across countries. The purpose of this four-country case studies analysis was to examine why and how improvements in BF practices occurred across four contrasting countries; Burkina Faso, the Philippines, Mexico and the United States of America. Literature reviews and key informant interviews were conducted to document BF trends over time, in addition to why and how BF protection, promotion and support policies and programmes were implemented at a national level. A qualitative thematic analysis was conducted. The 'Breastfeeding Gear Model' and RE-AIM (Reach; Effectiveness; Adoption; Implementation; and Maintenance) frameworks were used to understand and map the factors facilitating or hindering the scale up of the national programmes and corresponding improvements in BF practices. Each of the studied countries had different processes and timing to implement and scale up programmes to promote, protect and support breastfeeding. However, in all four countries, evidence-based advocacy, multisectoral political will, financing, research and evaluation, and coordination were key to fostering an enabling environment for BF. Furthermore, in all countries, lack of adequate maternity protection and the aggressive marketing of the breast-milk substitutes industry remains a strong source of negative feedback loops that are undermining investments in BF programmes. Country-specific best practices included innovative legislative measures (Philippines), monitoring and evaluation systems (United States of America), engagement of civil society (Mexico) and behavior change communication BF promotion (Burkina Faso) initiatives. There is an urgent need to improve maternity protection and to strongly enforce the WHO Code of Marketing of Breast-Milk Substitutes.

They push their products through me: health professionals' perspectives on and exposure to marketing of commercial milk formula in Cape Town and Johannesburg, South Africa - a qualitative study

OBJECTIVE

To understand the views of public and private sector health professionals on commercial milk formula, to describe their exposure to companies that market commercial milk formula within their workplaces and to describe their awareness of South African (SA) regulations.

DESIGN

A qualitative study consisting of semistructured interviews.

SETTING

The study was conducted in Cape Town and Johannesburg, SA.

PARTICIPANTS

Forty health professionals who had regular contact with pregnant or postnatal women were interviewed between February 2020 and February 2021.

RESULTS

Analysis of the interviews revealed six themes. Health professionals in the private sector reported frequent contact with industry representatives with over two-thirds reporting exposure to industry representatives to present products, provide training or sponsor educational activities. Participants held strong opinions regarding the equivalency of breastfeeding to commercial milk formula citing information from industry representatives and product packaging. Health professionals were very knowledgeable on so-called formulas for special medical purposes and these were valued as solutions to infant feeding challenges. Of the 40 health professionals interviewed, less than half (19) had ever heard of the SA regulation related to marketing of breast milk substitutes (R991).

CONCLUSIONS

This study demonstrates clearly that health professionals, particularly in the private sector, are exposed to and promote the use of commercial milk formula among SA women. The findings of this study should be used to catalyse policy responses, social movements, consumer and professional association action to strengthen monitoring and enforcement of the Code regulations in order to protect breastfeeding and support the optimal health and well-being of the population.

Exposure to marketing of breastmilk substitutes in Mexican women: Sources and scope

BACKGROUND

Aggressive and unregulated marketing of breastmilk substitutes (BMS) results in increased child morbidity and mortality. Unregulated BMS marketing is a major public health concern because it encourages formula consumption at the expense of breastfeeding. This study aimed to identify the sources and characterize the nature of exposure to marketing of BMS among Mexican mothers of children under 18 months of age. As a secondary objective we explored potential association between exposure to BMS marketing and infant feeding practices.

METHODS

Cross-sectional study, comprising a pre-piloted survey, was conducted between February 2020 to February 2021 with Mexican mothers of children under 18 months of age (n = 754), in two major cities in Mexico. Mothers were selected according to their current infant feeding practices (Breastfeeding only vs. Mixed feeding). We characterized the different BMS marketing sources and scope, and related them with infant feeding practices. In addition, we used logistic regression models to estimate the odds ratio for infant feeding practices by BMS marketing exposure or recommendation.

RESULTS

Mothers reported different sources of exposure to BMS promotion, including BMS advertisements in diverse media channels (41.6%), recommendation by a healthcare professional and/or relative (76.2%), and receiving a BMS sample at a hospital (18.6%). By contrast, only 36.5% recalled hearing or seeing breastfeeding information the previous year. The odds of mixed feeding were substantially higher, compared to breastfeeding, when mothers were recommended to use a BMS by doctors/pediatricians (OR: 3.96, 95% CI: 2.00, 7.83). Having seen or heard breastfeeding information in the previous year was associated with a lower risk of mixed feeding compared to breastfeeding only (OR: 0.59, 95% CI: 0.35, 0.99).

CONCLUSIONS

Mexican mothers of young children in the metropolitan areas studied were highly exposed to BMS marketing and through different mass media channels and inter-personal sources. Health care professionals, particularly doctors/pediatricians, are a source of BMS promotion that are likely to have a strong influence on maternal decisions about infant feeding practices. There is an urgent need to protect mothers and their families against unregulated BMS promotion through mass media channels and directly by influential individuals, including health care providers.

Scoping review of nutrition intervention and dietary assessment studies in Khmer populations living in Cambodia

BACKGROUND

This scoping review aims to describe the body of nutrition intervention and dietary assessment research undertaken with Khmer populations in Cambodia, as well as summarise the nutrition knowledge base and highlight priority areas for future research.

METHODS

Five databases and the grey literature were searched, following PRISMA-ScR guidelines. Studies involving dietary assessment or nutrition interventions published after 1992 were identified using specific search terms and extracted to a customised data extraction table for categorisation and analysis. Study participants were Khmer people of any age and gender, living in rural or urban Cambodia.

RESULTS

Of the 100 included studies, 58 were dietary assessment only studies, 24 were nutrition interventions only, and 18 studies involved both assessment of intake and an intervention. Sixty-eight percent of study populations were mothers and young children, of which 52 studies focused on children aged under 5 years. Nineteen interventions involved supplementation and six trialled fortification of rice or fish sauce. Anaemia was the most common nutrition condition studied (n = 17), followed by malnutrition (n = 15) and malnutrition risk factors (n = 11). General nutrition status was explored in 25 studies, and individual micronutrients that were studied included iron (n = 27), zinc (n = 6), vitamin A (n = 4) and thiamine (n = 3).

CONCLUSIONS

Diet-related research in Khmer populations in Cambodia has predominantly focused on dietary assessment or evaluation of interventions aimed at reducing malnutrition and resolving micronutrient deficiencies. Areas identified as emerging needs included non-communicable diseases, the ageing population and non-iron deficiency anaemia.

Breastfeeding and breastmilk substitute use and feeding motivations among mothers in Bandung City, Indonesia

Suboptimal breastfeeding is common in Indonesia, with only half of infants 0-5 months of age exclusively breastfed and feeding of breastmilk substitutes (BMS) highly prevalent among infants and toddlers. Various factors influence these feeding practices, including social norms, limited health system support and BMS manufacturer marketing practices. This cross-sectional survey aimed to identify the prevalence of breastfeeding and BMS feeding among children aged 0-35 months, explore socio-demographic characteristics and motivating factors associated with these feeding behaviours and identify the prevalence of mothers' exposure to BMS promotions. Indonesian mothers of children <3 years of age (n = 595) were interviewed in Bandung City health facilities using structured questionnaires. Although all children were ever breastfed, half of children across all age groups received BMS in the previous day. Maternal employment outside the home and insufficient breastmilk production were associated with BMS use. The most important motivational factors for feeding BMS were perceived benefits for growth, intelligence and immunity. Despite Indonesian legislation restricting some BMS marketing, 93% of mothers reported observing a BMS promotion outside the health system, with television, social media and newspapers as the most common sources. Half of mothers (43%) reported observing a BMS promotion within the health system, and half (46%) reported receiving recommendations from health workers to use BMS. Such high prevalence of BMS marketing may be influencing caregivers' feeding choices; stronger national legislation and implementation of laws are needed to ensure mothers' ability to make feeding choices free from manufacturer influence.

Trends and determinants of prelacteal feeding in Turkey: analysis of 2003-2018 demographic and health surveys

OBJECTIVE

The aim of the current study is to analyse the trends, determinants of prelacteal feeding (PLF) and its relations with the mode of delivery among infants <24 months over the years 2003-2018.

DESIGN

We pooled data from Turkey Demographic and Health Surveys (TDHS). The key outcome variable was PLF. Factors associated with PLF were analysed by using complex sample multiple logistic regression analysis, separately and merged database.

SETTING

TDHS in 2003, 2008, 2013 and 2018.

PARTICIPANTS

Mother-infant dyads (n 4942).

RESULTS

PLF rates fluctuated between 29·3 and 41·4 %. The most common types of PLF were infant formula (61·1 %) followed by sugar/glucose water (24·9 %) and plain water (9·3 %). PLF rate was 1·51 times higher (95 % CI 1·28, 1·78) in cases delivered by caesarean section as compared with those delivered by vaginal route. According to the initiation time of breast-feeding after delivery, the most significant absolute change in PLF rate was observed within 1 h (10·9 % increase). Delayed initiation of breast-feeding was associated with significantly higher odds of PLF compared with the first hour (1 to < 2 h: adjusted OR (AOR) 1·29, 95 % CI 1·04, 1·61; 2-23 h: AOR 1·73, 95 % CI 1·42, 2·11; ≥24 h: AOR 11·37, 95 % CI 8·81, 14·69).

CONCLUSIONS

To eliminate suboptimal breast-feeding practices, counselling on breast-feeding and delivery type during antenatal visits, postnatal breast-feeding support and social support should be provided to all mothers and families.

Predictors of breast milk substitute feeding among newborns in delivery facilities in urban Cambodia and Nepal

Introducing breast milk substitutes (BMS) in the first days after birth can increase infant morbidity and reduce duration and exclusivity of breastfeeding. This study assessed determinants of BMS feeding among newborns in delivery facilities in Phnom Penh, Cambodia, and Kathmandu Valley, Nepal. Cross-sectional surveys were conducted among mothers upon discharge from health facilities after delivery: 304 mothers in Kathmandu Valley and 306 mothers in Phnom Penh participated. On the basis of a conceptual framework for prelacteal feeding, multivariable logistic regression was used to identify factors associated with BMS feeding prior to facility discharge. In both Phnom Penh and Kathmandu Valley, feeds of BMS were reported by over half of mothers (56.9% and 55.9%, respectively). Receiving a health professional's recommendation to use BMS increased the odds of BMS feeding in both Kathmandu Valley and Phnom Penh (odds ratio: 24.87; confidence interval [6.05, 102.29]; odds ratio: 2.42; CI [1.20, 4.91], respectively). In Kathmandu Valley, recommendations from friends/family and caesarean delivery were also associated with BMS use among mothers. Early initiation of breastfeeding and higher parity were protective against the use of BMS in Kathmandu Valley. Breastfeeding support from a health professional lowered the odds of BMS feeding among newborns. Exposure to BMS promotions outside the health system was prevalent in Phnom Penh (84.6%) and Kathmandu Valley (27.0%) but was not associated with BMS feeds among newborns. Establishment of successful breastfeeding should be prioritized before discharging mothers from delivery facilities, and health professionals should be equipped to support and encourage breastfeeding among all new mothers.

Age-Appropriate Feeding Practices in Cambodia and the Possible Influence on the Growth of the Children: A Longitudinal Study

Age-appropriate feeding practice (ADF) during early childhood are vital for optimal nutrition. This longitudinal study determined the effect of selected risk factors and ADF, as described by the National Nutritional Recommendations, on linear and ponderal growth of children below 24 months of age. Weight and length measures were used to calculate z-scores of anthropometric measures by WHO standards. The prevalence of stunting increased from 13.2% to 32.4% over time, while prevalence of wasting remained stable (14.5%). At first visit, 43% of children of all ages complied with ADF criteria, a proportion which decreased to 7.1% in follow-up. The quality of feeding practices for children above 12 months of age was the poorest, where at the last visit, only 6% complied with the criteria for ADF. The linear mixed-effect models found the association between ADF and ponderal growth to be significant (weight-for-height estimate: 0.05 SD). In Cambodia, Ratanakiri province, ADF was the second largest determinant for ponderal growth. We recommend province specific public health actions. For children above 6 months, the quantity of food given needs to be increased, followed by the meal frequency. Mothers' educational level, improved sanitation, and drinking water quality were among strongest predictors of a child's growth.
