It has long been recognized that intestinal parasite infections and undernutrition are closely linked. However, little is known about the role of intestinal parasite infections (IPIs), or parasite clearance, in these processes. The aim of this scoping review was to summarize published evidence on the association between IPIs and body composition.

The aim of this study is to provide an overview of the geographical distribution of Ascariasis, Amebiasis and Giardiasis, and to identify specific geographical, socioeconomic and environmental factors that are associated with the incidence of these infections in Mexican children. We made use of publicly available data that was reported by federal organizations in Mexico for the year 2010. The contribution of geographical, socioeconomic and environmental factors to the incidence of infections was assessed by a multivariable regression model using a backwards selection procedure.

Context: Despite an improvement in food security and the delivery of nutritional supplements to children living in impoverished parts of the world, poor growth is still highly prevalent. Given that the microbiome is related to both nutrient absorption, as well as overweight/obesity, it may play a central role in limiting or modifying normal growth processes while contributing to chronic disease risks.

Objective: The objective of this paper is to describe normal growth processes, the role of the microbiome in supporting or disrupting normal growth processes, and its potential impact on long-term health.

Objective: Measurements of length at birth, or in the neonatal period, are challenging to obtain and often discounted for lack of validity. Hence, classical 'under-5' stunting rates have been derived from surveys on children from 6 to 59 months of age. Guatemala has a high prevalence of stunting (49.

Soil-transmitted helminth (STH) infections and zinc deficiency are often found in low- and middle-income countries and are both known to affect child growth. However, studies combining data on zinc and STH are lacking. In two studies in schoolchildren in Cuba and Cambodia, we collected data on height, STH infection and zinc concentration in either plasma (Cambodia) or hair (Cuba).

Background: In 2003, the World Health Organization (WHO) and the Pan American Health Organization (PAHO) published "Guiding principles for complementary feeding of the breastfed child," which includes a series of 10 recommendations.

Objective: To illustrate the challenges in creating operative criteria for the evaluation of concordance with the tenets of the WHO/PAHO Guiding Principles recommendations.

Methods: We set out to define operative criteria for the evaluation of adherence to the tenets of the WHO/PAHO Guiding Principles.

Human immunodeficiency virus (HIV) remains a highly stigmatised condition for people living with HIV (PLWH) and people living close to them (PLC) globally. The research objectives for this study were to explore and describe how HIV stigma and disclosure experiences impact the lives of PLWH and to explore whether there are differences between experiences in urban and rural settings. A qualitative approach was followed and participants were selected through purposive voluntary sampling.

The WHO recommends exclusive breastfeeding during the first 6 mo of life; however, deviations from this recommendation are widespread. The objective of the current study was to evaluate exclusive and predominant breastfeeding rates, as defined by the WHO, in a cross-sectional sample of Guatemalan children using retrospective records on the temporal pattern of introducing foods and beverages before 6 mo. Mothers of 150 infants, aged 6 to 23 mo, attending a public health clinic were interviewed about early life feeding practices with a structured questionnaire.

Early linear growth in Guatemala has historically been compromised, resulting in adults of short stature. We hypothesized that the rate of short stature among mothers in the Western Highlands would have tracked from their own childhood when younger than 5 years, and that maternal weight declines progressively from delivery through lactation. Maternal weight and height were collected in 542 lactating mothers of infant and toddlers, ranging in age from 15 to 48 years, with subsequent classification of mothers for short stature (relative to the 1977 World Health Organization/National Center for Health Statistics growth curves) and for underweight (body mass index [BMI], <18.
