Infant feeding practices in the Peruvian Amazon: implications for programs to improve feeding / Prácticas de alimentación de lactantes en la Amazonia Peruana: implicaciones para los programas de mejora de la alimentación

OBJECTIVE: To characterize feeding practices in a community in the Peruvian Amazon and to consider how this information could be used to strengthen programs and policies designed to improve nutrition and reduce child malnutrition in vulnerable communities METHODS: Data from three structured questionnaires were combined to produce a comprehensive depiction of feeding in a sample of 246 infants from birth through 8 months of life in the community of Santa Clara de Nanay near Iquitos, Peru. Breastfeeding initiation practices, exclusive breastfeeding in the first 180 days of life, the introduction of solids, and complementary feeding practices from 6-8 months, were described and related to maternal, infant, and household characteristics, including food insecurity RESULTS: The median duration of exclusive breastfeeding was 19 days. However, over the first 180 days of life, children were exclusively breastfed on 46.1% of days. Overall, 68.3% of infants received some semi-solid or solid food between 0-6 months and all had received semi-solids by the end of 8 months of age. The proportion of infants consuming a minimally acceptable (frequent and diverse) complementary diet was 2.9%, 7.9%, and 16.1% at 6, 7, and 8 months respectively CONCLUSIONS: Although breastfeeding is nearly universal, promotion programs are needed in Santa Clara to 1) delay the introduction of plain water, other non-breast milk liquids, and semi-solid foods; 2) extend the period of exclusive breastfeeding; and 3) increase food diversity and the frequency of feeding during the period of complementary feeding. These results can be used to guide programs and policies to improve nutrition and reduce child malnutrition.

OBJETIVOS: Determinar las prácticas de alimentación en una comunidad de la Amazonia peruana y analizar cómo esta información podría usarse para fortalecer los programas y las políticas diseñadas para mejorar la nutrición y reducir la desnutrición infantil en las comunidades vulnerables MÉTODOS: Se combinaron datos de tres cuestionarios estructurados para obtener una descripción integral de la alimentación en una muestra de 246 lactantes, desde el nacimiento y hasta los 8 meses de vida, en la comunidad de Santa Clara de Nanay cerca de Iquitos, Perú. Se describieron las prácticas de iniciación de la lactancia materna, lactancia materna exclusiva en los 180 primeros días de vida e introducción de alimentos sólidos y las prácticas de alimentación complementaria desde los 6 hasta los 8 meses, y se las relacionó con las características maternas, de los lactantes y los hogares, lo que incluyó la inseguridad alimentaria RESULTADOS: La mediana de duración de la lactancia materna exclusiva fue 19 días. Sin embargo, en los 180 primeros días de vida los niños habían sido amamantados exclusivamente 46,1% de los días. En términos generales, 68,3% de los lactantes recibieron algún alimento semisólido o sólido entre los 0 y los 6 meses de vida, y hacia el final del octavo mes de vida todos habían recibido alimentos semisólidos. La proporción de lactantes cuyo régimen alimentario complementario había sido mínimamente aceptable (frecuente y diverso) fue 2,9% a los 6 meses, 7,9% a los 7 meses y 16,1% a los 8 meses CONCLUSIONES: A pesar de que la lactancia materna es prácticamente universal, en Santa Clara son necesarios programas de promoción para 1) retrasar la introducción de agua corriente, otros líquidos fuera de la leche materna y alimentos semisólidos; 2) extender el período de lactancia materna exclusiva, y 3) aumentar la diversidad de los alimentos y la frecuencia de la alimentación durante el período de alimentación complementaria. Estos resultados pueden ser útiles para guiar los programas y las políticas de mejora de la nutrición y reducir la desnutrición infantil.

How much does your baby cry?: Expectations, patterns and perceptions of infant crying in Mexico

Background: A limited number of studies have examined infant crying patterns in less affluent societies, but none of them have been longitudinal in nature. The aim of this study was to describe reported infant crying patterns in a cohort of Mexican infants and examine how these are associated with crying-related maternal expectations, general perceptions and help-seeking behavior. Methods: Observational cohort study, 204 primiparous mothers and their infants, recruited at birth and visited in their homes at nine different time points from 1 to 24 weeks of infant age. Results: Mothers reported that their infants cried less than infants in other more affluent societies, although not less frequently. A previously reported evening clustering of crying was present, with a subtle 24-h crying peak emerging around 2 to 4 weeks. Having an expectation of an infant who will be difficult to soothe and/or an increased report of crying frequency were associated with perceptions of maternal anguish, which was associated with maternal concern and help-seeking behaviors related to crying. Conclusions: Similarities and differences were found in the crying patterns reported by mothers of Mexican infants and others previously studied. Expectations and reports of crying behavior were associated with maternal perceptions, which may have a role in reducing crying-related anguish and demand on health services.

Association between anaemia during pregnancy and blood loss at and after delivery among women with vaginal births in Pemba Island, Zanzibar, Tanzania.

The study sought to identify determinants of blood loss at childbirth and 24 hours postpartum. The study was nested in a community-based randomized trial of treatments for anaemia during pregnancy in Wete Town, Pemba Island, Zanzibar, United Republic of Tanzania. Status of anaemia during pregnancy, nutritional information, obstetric history, and socioeconomic status were assessed at enrollment during routine antenatal care. Pregnant women presented for spontaneous vaginal delivery, and nurse-midwives collected information on labour and delivery via partograph. Blood-stained sanitary napkins and pads from childbirth and 24 hours postpartum were quantified using the alkaline hematin method. Moderate-to-severe anaemia (Hb <90 g/L) at enrollment was strongly associated with blood loss at delivery and the immediate postpartum period, after adjusting for maternal covariates and variables of biological relevance to blood loss. Greater blood loss was associated (p<0.10) with duration of the first stage of labour, placental weight, receipt of oxytocin, preterm birth, and grand multiparity. The findings provide unique evidence of a previously-suspected link between maternal anaemia and greater blood loss at childbirth and postpartum. Further research is needed to confirm these findings on a larger sample of women to determine whether women with moderate-to-severe anaemia are more likely to experience postpartum haemorrhage and whether appropriate antenatal or peripartum care can affect the relationships described here.

Zinc supplementation and serum zinc during diarrhea.

OBJECTIVE: Zinc deficiency is very common in developing countries and is more pronounced during an episode of diarrhea. Supplementation with zinc improves diarrhea and might correct zinc deficiency in both the short and longer term. METHOD: We conducted a nested study within a cluster randomized treatment trial. Fifty children with diarrhea living in the zinc treated clusters, 50 children with diarrhea living in control clusters, and 50 healthy children living in the control clusters were enrolled. We assessed serum zinc at the start of the diarrhea episode, which was 1-3 days after supplementation began in zinc treated children, and again one week after the diarrhea ended and supplementation ceased. Baseline characteristics and serum zinc concentration were assessed. RESULTS: Serum zinc was low in 44% of healthy children at the first blood draw. Compared to healthy controls, serum zinc was 3.1 mmol/L higher among children with diarrhea who were supplemented with zinc at first blood draw and 1.3 mmol/L higher 3 weeks later. CONCLUSION: Zinc supplementation enhances serum zinc concentration when given as a treatment for diarrhea and helps children maintain a more adequate zinc status during the convalescent period.
