MALNUTRITION, WITH ITS 2 CONSTITUENTS of protein–energy malnutrition and micronutrient deficiencies, continues to be a major health burden in developing countries. It is globally the most important risk factor for illness and death, with hundreds of millions of pregnant women and young children particularly affected. Apart from marasmus and kwashiorkor (the 2 forms of protein– energy malnutrition), deficiencies in iron, iodine, vitamin A and zinc are the main manifestations of malnutrition in developing countries. In these communities, a high prevalence of poor diet and infectious disease regularly unites into a vicious circle. Although treatment protocols for severe malnutrition have in recent years become more efficient, most patients (especially in rural areas) have little or no access to formal health services and are never seen in such settings. Interventions to prevent protein– energy malnutrition range from promoting breast-feeding to food supplementation schemes, whereas micronutrient deficiencies would best be addressed through food-based strategies such as dietary diversification through home gardens and small livestock. The fortification of salt with iodine has been a global success story, but other micronutrient supplementation schemes have yet to reach vulnerable populations sufficiently. To be effective, all such interventions require accompanying nutrition-education campaigns and health interventions. To achieve the hunger- and malnutrition-related Millennium Development Goals, we need to address poverty, which is clearly associated with the insecure supply of food and nutrition.

Objective: To describe fruit and vegetable intake of 11-year-old children in ten European countries and compare it with current dietary guidelines.Design: Cross-sectional survey. Intake was assessed using a previously validated questionnaire containing a pre-coded 24 h recall and an FFQ which were completed in the classroom. Portion sizes were calculated using a standardized protocol.Setting: Surveys were performed in schools regionally selected in eight countries and nationally representative in two countries.Subjects: A total of 8158 children from 236 schools across Europe participating in the PRO GREENS project.Results: The total mean consumption of fruit and vegetables was between 220 and 345 g/d in the ten participating countries. Mean intakes did not reach the WHO population goal of ≥400 g/d in any of the participating countries. Girls had a significantly higher intake of total fruit and vegetables than boys in five of the countries (Sweden, Finland, Iceland, Bulgaria and Slovenia). Mean total fruit intake ranged between 114 and 240 g/d and vegetable intake between 73 and 141 g/d. When using the level ≥400 g/d as a cut-off, only 23·5 % (13·8–37·0 %) of the studied children, depending on country and gender, met the WHO recommendation (fruit juice excluded).Conclusions: Fruit and vegetable consumption was below recommended levels among the schoolchildren in all countries and vegetable intake was lower than fruit intake. The survey shows that there is a need for promotional activities to improve fruit and vegetable consumption in this age group.

For the optimal nutrition of children under 2 years of age, it is considered important that they be exclusively breastfed for the first 6 months before being given complementary food. A cross-sectional nutritional baseline survey was undertaken in 2011 in the Kasungu and Mzimba Districts of Malawi to assess the nutritional status of children under 2 years of age and its determinants in order to prepare a nutrition education intervention programme. The intention of this study was to assess the nutritional status of infants aged 0-<6 months with regard to food intake. Interviews were conducted on randomly selected families with children under 2 years; anthropometric measurements were obtained from mothers and their children. Only infants between 0 and <6 months were selected for analysis (n = 196). An ANCOVA test was performed on age of the infant with mothers' height and weight as covariates. Prevalence of stunting (infants' length-for-age Z-score (LAZ) <-2SD) was 39%, wasting (WLZ <-2SD) 2%, and underweight (WAZ <-2SD) 13%. Of the infants under 6 months, 43% were exclusively breastfed. Predominant breastfeeding and mixed breastfeeding were less common (21% and 36%, respectively). The ANCOVA confirmed the association between exclusive breastfeeding and LAZ and WAZ: exclusively breastfed infants had a higher mean (SE) LAZ (-1.13, 0.12) and WAZ (-0.41, 0.13) than infants not being exclusively breastfed (-1.59, 0.11, and -0.97, 0.11, respectively). There was no overall significant association between breastfeeding practice and WLZ. Exclusive breastfeeding of infants under 6 months is associated with higher mean LAZ and WAZ. Promotion of exclusive breastfeeding in low-income countries is important in preventing growth retardation.

Objective: Lack of diversity is a major factor contributing to inadequate nutrient intakes among children during the complementary feeding period in many rural areas in developing countries. This has been attributed to inadequate feeding practices and nutrition knowledge among their caregivers. The aim of the present study was to assess the effect of an educational intervention on children’s dietary diversity and nutrition knowledge of caregivers.Design: Cluster randomization was applied and twenty matched village pairs were randomly assigned to the intervention or control group. The nutrition education intervention consisted of four sessions comprising of group trainings and cooking demonstrations that were conducted over a period of 5 months.Setting: Households in rural communities in Bondo and Teso South sub-counties, western Kenya.Subjects: Caregivers with children aged 6–17 months receiving nutrition education.Results: The children’s dietary diversity scores (CDDS) and nutrition knowledge scores of the caregivers improved significantly in the intervention group at endline. The treatment effect on CDDS was positive and significant (P=0·001). The CDDS rate of the children in the intervention group was 27 % larger than it would have been without the treatment effect. The intervention also had a significant effect on the caregivers’ nutrition knowledge scores (incidence rate ratio=2·05;P<0·001). However, the nutrition knowledge of the caregivers did not have a significant effect on CDDS (P=0·731).Conclusions: The nutrition education intervention led to improvements in children’s dietary diversity and nutrition knowledge of the caregivers.

Diet and physical activity before and during pregnancy affect short- and long-term health of mother and child. The energy needs at the end of pregnancy increase only by about 10% compared to nonpregnant women. An excessive energy intake is undesirable since maternal overweight and excessive weight gain can increase the risks for a high birth weight and later child overweight and diabetes. Maternal weight at the beginning of pregnancy is especially important for pregnancy outcome and child health. Women should strive to achieve normal weight already before pregnancy. Regular physical activity can contribute to a healthy weight and to the health of pregnant women. The need for certain nutrients increases more than energy requirements. Before and during pregnancy, foods with a high content of essential nutrients should be preferentially selected. Supplements should include folic acid and iodine, iron (in case of suboptimal iron stores), the ω-3 fatty acid docosahexaenoic acid (in case of infrequent consumption of ocean fish) and vitamin D (in case of decreased sun exposure and decreased endogenous vitamin D synthesis). Pregnant women should not smoke and not stay in rooms where others smoke or have smoked before (passive smoking). Alcohol consumption should be avoided, since alcohol can harm unborn children.
