Abstract
Prechewing of food by caregivers is a common infant feeding practice both globally and in the United States, where the highest rates of the practice are found among African-Americans and Alaska Natives. The objective of this study was to determine if prechewing of infant food is associated with increased diarrhoea prevalence of 10-month-old infants in the United States. The study used cross-sectional data from the Infant Feeding Practices Study II to test for associations between prechewing and 2-week-period prevalence of infant diarrhoea. At 10 months of age, infants who received prechewed food (n = 203) had a diarrhoea prevalence of 16.1%, compared with 10.9% of children who did not receive prechewed food (n = 1567) [relative risk (RR) = 1.48, 95% confidence interval (CI) 1.03–2.11]. After adjusting for covariates, including breastfeeding and consuming sweets and dairy, prechewing was associated with a 58% higher risk (RR = 1.58, 95% CI 1.10–2.26) of 2-week diarrhoea prevalence. Consumption of sweets (RR = 1.35, 95% CI 1.03–1.78) and dairy (RR = 1.41, 95% CI 1.03–1.93) was also associated with increased diarrhoea risk. Continued breastfeeding at 10 months of age was associated with a reduced risk of diarrhoea (RR = 0.68, 95% CI 0.50–0.91). Prechewing of infant food is associated with increased diarrhoea among 10-month-old infants. The high RR found in this study suggests that prechewing may be an important factor in public health efforts to reduce the burden of diarrhoeal disease. However, further research is needed to establish that prechewing causes increased diarrhoea risk and to explore potential benefits of prechewing.

Background Up-to-date evidence on levels and trends for age-sex-specifi c all-cause and cause-specifi c mortality is essential for the formation of global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013) we estimated yearly deaths for 188 countries between 1990, and 2013. We used the results to assess whether there is epidemiological convergence across countries. Methods We estimated age-sex-specifi c all-cause mortality using the GBD 2010 methods wi...

Premastication-defined as pre-chewing of food for infants by their caregiver-is a common feeding practice in various societies. To date the impact of premastication on children's health including the potential for transmission of infectious diseases is not well understood. Since there are no epidemiologic data on premastication from resource poor regions in Central Africa, we investigated the epidemiology and demographic variables associated with premastication in Central Africa. Between 2011 an...

Dear Editor, Gaur et al.1 reported HIV infection in three children in the United States from infected adults feeding them prechewed food. This practice is common among HIV-infected care providers around the world.2–6 Prechewing involves chewing food before feeding it to a child. Prewarming (or precooling) involves holding food in the mouth to adjust the temperature before offering it to a child. These practices may expose the child to blood from the mouth of an HIV-infected adult. The context of...

Introduction of pre-chewed foods to infants during weaning is a common parental practice. However, children can be exposed to mouth-to-mouth transmission of infectious and multi-drug resistant bacteria through pre-chewed foods, during complementary feeding. The aim of this study was to investigate the antibiotic resistance profiles of 103 easily-culturable oral bacterial strains of nursing parents, isolated from their pre-chewed meat samples. Using agar disk-diffusion and modified agar well-diff...

Summary Background Information about the distribution of causes of and time trends for child mortality should be periodically updated. We report the latest estimates of causes of child mortality in 2010 with time trends since 2000. Methods Updated total numbers of deaths in children aged 0–27 days and 1–59 months were applied to the corresponding country-specific distribution of deaths by cause. We did the following to derive the number of deaths in children aged 1–59 months: we used vital regis...

OBJECTIVES: Deaths due to diarrhea among US children declined substantially from the 1960s through the 1980s, but have not been recently assessed. We examined diarrhea-associated mortality among young US children from 1992 to 2006 to establish baseline estimates through which the effect of rotavirus vaccines, introduced in 2006, can be assessed. METHODS: National Center for Health Statistics multiple cause-of-death mortality data were used to examine diarrhea-associated deaths and death rates am...

Premastication of foods for infants was a crucial behavioural adaptation to neoteny that ensured nutritional adequacy during the period of complementary feeding throughout the course of human evolution until recent times. While the paps and gruels of agricultural systems provided an alternative and modern food technology appears to make it unnecessary, we argue that, in addition to its role in nutrition, premastication also played a crucial role in supporting infant health. Its abandonment, part...

OBJECTIVES: Although some caregivers are known to premasticate food for infants, usually during the weaning period, HIV transmission has not been linked to this practice. We describe 3 cases of HIV transmission in the United States possibly related to this practice. PATIENTS AND METHODS: Three cases of HIV infection were diagnosed in children at ages 9, 15, and 39 months; clinical symptomatology prompted the testing. A thorough investigation to rule out alternative modes of transmission was cond...

Abstract Premasticated food transfer, when an individual partially breaks down food through chewing and feeds it to another individual, usually mouth-to-mouth, is described widely across human cultures. This behavior plays an important role in modern humans’ strategy of complementary feeding, which involves supplementing maternal milk in infant diets with processed, easily digestible versions of adult foods. The extent to which other primates engage in premasticated food transfer with infants is...

: Premastication is thought to be an adaptive behavior in the introduction of complementary plant-bassed food to infants. It arouses controversy, however, because of the potential for transmitting saliva-born infectious diseases. The aim of this study was to explore whether premastication by healthy caregivers was associated with children's health and behavior. The data were collected as part of the Maternal and Infant Nutrition and Growth study. From 8 cities in China, 1341 pairs of infants/tod...

: Premastication of infant food by caregivers is common in Laos. Premastication is hypothesized to have both positive and negative implications for children, but the net effect of premastication on child health and nutrition is largely unknown because of a lack of research. This study quantitatively describes premastication in 5 provinces of Laos and examines the associations between premastication and the length of young children. We analyzed cross-sectional data from the Laos 2015 Food and Nut...

Based on a paper by Conkle et al 2016, in which the authors use a descriptive epidemiological design to examine the relationship of premastication and other dietary behavioral variables to childhood diarrhea in the US, we address larger issues of “plausible causality” and the challenges involved in moving from epidemiological studies to public health policy. Drawing on examples from breastfeeding research and water, sanitation and hygiene (WASH) research, we discuss the following propositions: 1...
