Maternal stool samples were examined for the presence of intestinal nematodes and protozoa. Questionnaires were used to characterize breastfeeding practices exclusivity and frequency and support, hygiene latrine use and household faucetand infant diarrhoea.
Moms that need a fuck Gladstone qc of SCM may improve early infant growth, but public health measures that increase breastfeeding frequency and reduce faecal—oral contamination may be required to minimize low head circumference. Subclinical mastitis may be an underappreciated determinant of underweight, stunting, and low head circumference in breastfed infants prior to 6 months of age.
Promoting higher breastfeeding frequency may be beneficial in reducing the risk of low head circumference even in populations where breastfeeding frequency falls within norms. Public health professionals may be interested in our observation that maternal Entamoeba coli increased the likelihood of low head circumference suggesting that faecal—oral contamination may be associated with early brain development.
This paper expands the paradigm for early infant growth faltering from a focus on infant diarrhoea and nutrition to one that incorporates maternal factors. Explanations for infant growth faltering prior to 6 months of age are limited as studies have rarely focused on this age group. However, the relationship of environmental Moms that need a fuck Gladstone qc to growth faltering and stunting in young infants is complex and not fully understood Keusch et al.
Recently, it was proposed that the considerable fraction of unexplained variability in early infant growth faltering may relate to a more prominent role of maternal health and breastfeeding practices than ly recognized Mosites et al. One understudied maternal condition is subclinical mastitis SCM. Milk stasis contributes to SCM because it creates ideal conditions for bacterial overgrowth and breast inflammation WHO, Stasis usually occurs when breast milk is not efficiently removed because of restricted flow due to poor infant feeding practices or because reduced breastfeeding frequency or duration lowers milk volume WHO, SCM has been associated with poor maternal and breast health and nonexclusive breastfeeding Kasonka et al.
Lack of access to suitable water and sanitation infrastructure is a common experience for breastfeeding mothers in developing countries. This creates an unhygienic environment where mothers and their infants may be exposed to faecal—oral transmission of pathogens Keusch et al. These nonpathogenic protozoans are used as indicators of poor hygiene and sanitation given their association with poverty Ignacio et al. To date, research exploring the determinants of infant growth faltering has not simultaneously evaluated the contribution of breastfeeding practices, SCM, and indicators of sanitation and hygiene, even though regions where SCM and infant growth faltering coexist typically have poor sanitation.
The objective of this study was to determine if SCM, poor breastfeeding practices, and maternal faecal—oral contamination as measured by intestinal nematodes and protozoa were associated with higher odds of stunting, underweight, and low head circumference. Between June and Januarycomadronas traditional midwives and community healthcare workers CHWs recruited breastfeeding mother—infant dy at 0—6 weeks or 4—6 months of age. Institutional ethical approval was obtained, and all mothers provided fully informed consent.
Breastfeeding practices exclusive, predominant, or mixed feeding; WHO,breastfeeding frequency, and breastfeeding support provider and problems were queried by CHWs. Detailed methodology has been ly published Chomat et al.
In brief, two trained Guatemalan nutritionists measured maternal weight kgheight cm and infant length, and weight and head circumference in triplicate using an infantometer SECAa digital infant scale SECAand a head circumference baby band SECArespectively. These anthropometric measures were completed on the same day as breast milk collection.
Infant age was calculated using date of birth recorded on the mother's health card or in the absence of a card or as reported by the mother. Maternal body mass index BMI was calculated. A single stool sample was analysed using direct smear by an experienced laboratory technician. Presence of intestinal nematodes AscarisTrichurishookworm and both pathogenic Giardia spp, Entamoeba histolyticaand Entamoeba dispar and nonpathogenic B. A single, unilateral breast milk sample, from the breast not recently used for feeding, was collected under the supervision of a trained comadrona.
The lower limits of detection were 1. Multiple logistic regression analysis was used to examine hypothesized associations of SCM, breastfeeding practices, indicators of faecal—oral contamination with infant stunting, underweight, and low head circumference while controlling for maternal anthropometry and lactation stage.
To build individual anthropometric models, variables were grouped into common themes: maternal delivery frequency of antenatal care, delivery locationmaternal characteristics age, age at first pregnancy, weight, height, BMI, marital status, highest level of education, parity, occupation, and languagematernal intestinal protozoa B. The attributable risk of SCM for each anthropometric measurement was assessed. A comparison of factors based on subclinical mastitis status of mothers ab.

Multiple logistic regression models were created for infant stunting, underweight, and low head circumference Table 3. Our showed that SCM increased the odds of stunting, underweight, and low head circumference.
They also provide preliminary evidence that maternal health status during early lactation may be an underappreciated factor associated with infant growth faltering in breastfed infants prior to 6 months of age. Our also revealed that the presence of maternal nonpathogenic protozoans were associated with an increased likelihood of low head circumference and showed that higher breastfeeding frequencies were associated with a lower risk of low head circumference.
Together, these findings provide novel insights into how maternal health and breastfeeding practices may contribute to early infant growth faltering in the first 6 months of life. To our knowledge, ours is the first study to report that SCM also increased the odds of low head circumference.
Among these, we may consider ruling out lowered milk intake due to stasis given that mothers did not report problems with breastfeeding and both mothers with and without SCM continued breastfeeding without reporting insufficient milk volume or obstruction of milk flow. Moreover, the possibility that SCM altered the nutritive value of milk is supported by findings that show lower milk lactose Fetherston et al. Furthermore, it has been reported that the Na:K ratio was associated with higher concentrations of milk cytokines Filteau et al. These observations support the possibility that the nutritive value of milk from mothers with SCM may be altered by asymptomatic breast inflammation.
Collectively, these findings provide evidence that SCM for several reasons may be an overlooked maternal factor that underscores growth faltering in breastfed infants. Subclinical mastitis and its potential impact on the composition and nutritive value of breastmilk is only one factor possibly associated with early infant growth. Poor hygiene and sanitation can contribute to environmental enteropathy Keusch et al. Yet neither our indicators of hygiene latrine, faucet, faecal—oral contamination nor infant Moms that need a fuck Gladstone qc emerged in models for stunting or for underweight.
In contrast, however, the odds of low head circumference were higher if maternal stool samples contained Entamoeba coli. This nonpathogenic protozoan is transmitted through the faecal—oral route indicating an unhygienic environment. However, there is very little available information that could explain a direct link between maternal Entamoeba coli and low infant head circumference.
Thus, at best, the relationship may be indirect in that Entamoeba coli may be a biomarker associated with other maternal faecal pathogens or health status. The importance of breast milk for infant nutrition, growth, and development is well established Neville et al.
It is recommended that breastfeeding be initiated within 1 hr of birth and that mothers exclusively or predominantly breastfeed prior to 6 months and breastfeed at least 8—12 times every 24 hr WHO, One study had observed that infant weight and breastfeeding frequency were independently associated with breast milk intake and that the effect of SCM on milk volume disappeared if both infant weight and feeding frequency were entered in multiple linear regression models Aryeetey et al. Despite inclusion of both variables in our study, SCM remained in our models and was associated with the highest attributable risk factor of SCM with low head circumference.
Several limitations are present. Others had reported in older infants that it was difficult to determine if higher breastfeeding frequency or higher infant weight were driving milk intakes Kumwenda et al. Only maternal and not infant stool samples were collected, and episodes of infant diarrhoea as well as breastfeeding frequency may have been subject to recall bias. Reducing growth faltering in breastfed infants prior to 6 months of age has been a challenge in part because recognition of the primary drivers of infant growth faltering is incomplete Eriksen et al.
Our findings provide evidence that two maternal health conditions, SCM and maternal faecal—oral contamination, may play a more prominent role in early infant growth faltering than ly recognized and that promotion of higher breastfeeding frequency may reduce the risk of low head circumference, at least in populations where growth faltering is of concern.
These findings expand the paradigm for early infant growth faltering from a focus on dietary interventions Moms that need a fuck Gladstone qc preventing infant diarrhoea to include maternal health status and the contribution of SCM, hygiene, and early breastfeeding practices to growth of breast fed infants.
