Health Extension Workers’ Knowledge and Knowledge-Sharing Effectiveness of Optimal Infant and Young Child Feeding Are Associated With Mothers’ Knowledge and Child Stunting in Rural Ethiopia

Background Malnutrition continues to be a critical public health problem in sub-Saharan Africa. For example, in East Africa, 48 % of children under-five are stunted while 36 % are underweight. Poor health and poor nutrition are now more a characteristic of children living in the urban areas than of children in the rural areas. This is because the protective mechanism offered by the urban advantage in the past; that is, the health benefits that historically accrued to residents of cities as compared to residents in rural settings is being eroded due to increasing proportion of urban residents living in slum settings. This study sought to determine effect of mother’s education on child nutritional status of children living in slum settings. Methods Data are from a maternal and child health project nested within the Nairobi Urban Health and Demographic Surveillance System (NUHDSS). The study involves 5156 children aged 0–42 months. Data on nutritional status used were collected between October 2009 and January 2010. We used binomial and multiple logistic regression to estimate the effect of education in the univariable and multivariable models respectively. Results Results show that close to 40 % of children in the study are stunted. Maternal education is a strong predictor of child stunting with some minimal attenuation of the association by other factors at maternal, household and community level. Other factors including at child level: child birth weight and gender; maternal level: marital status, parity, pregnancy intentions, and health seeking behaviour; and household level: social economic status are also independently significantly associated with stunting. Conclusion Overall, mothers’ education persists as a strong predictor of child’s nutritional status in urban slum settings, even after controlling for other factors. Given that stunting is a strong predictor of human capital, emphasis on girl-child education may contribute to breaking the poverty cycle in urban poor settings.

Malnutrition is the underlying cause of half of child mortality. Many programmes attempt to remedy this issue but there is a lack of evidence on effective ways to decrease child malnutrition. We did a cluster-randomised trial of an educational intervention in a poor periurban area (ie, shanty town) of Peru. Guided by formative research, the intervention aimed to enhance the quality and coverage of existing nutrition education and to introduce an accreditation system in six government health facilities compared with six control facilities. The primary outcome measure was growth that was measured by weight, length, and Z scores for weight-for-age and length-for-age at age 18 months. Main secondary outcomes were the percentage of children receiving recommended feeding practices and the 24-h dietary intake of energy, iron, and zinc from complementary food at ages 6, 9, 12, and 18 months. Analysis was by intention to treat. We enrolled a birth cohort of 187 infants from the catchment areas of intervention centres and 190 from control areas. Caregivers in intervention areas were more likely to report receiving nutrition advice from the health service than were caregivers in control health facilities (16 [52%] of 31 vs 9 [24%] of 37, p=0.02). At 6 months more babies in intervention areas were fed nutrient-dense thick foods at lunch (a recommended complementary feeding practice) than were controls (48 [31%] of 157 vs 29 [20%] of 147; difference between groups 19 [11%], p=0.03). Fewer children in intervention areas failed to meet dietary requirements for energy (8 months: 30 [18%] of 170 vs 45 [27%] of 167, p=0.04; 12 months: 64 [38%] of 168 vs 82 [49%] of 167, p=0.043), iron (8 months: 155 [91%] of 170 vs 161 [96%] of 167, 9 months: 152 [93%] of 163 vs 165 [99%] of 166, p=0.047), and zinc (9 months: 125 [77%] of 163 vs 145 [87%] of 166, p=0.012) than did controls. Children in control areas were more likely to have stunted growth (ie, length for age less than 2 SD below the reference population median) at 18 months than children in intervention groups (26 [16%] of 165 vs 8 [5%] of 171; adjusted odds ratio 3.04 [95% CI 1.21-7.64]). Adjusted mean changes in weight gain, length gain, and Z scores were all significantly better in the intervention area than in the control area. Improvement of nutrition education delivered through health services can decrease the prevalence of stunted growth in childhood in areas where access to food is not a limiting factor.

Though a great interest and willingness to nutrition therapy, there is an insufficient practice compared to the proposed ESPEN guidelines for nutrition therapy. The aim of this questionnaire was to study doctors and nurses' self-reported knowledge in nutritional practice, with focus on ESPEN's guidelines in nutritional screening, assessment and treatment. A questionnaire about different aspects of nutritional practice was answered by 4512 doctors and nurses in Denmark, Sweden and Norway. The most common cause for insufficient nutritional practice was lack of nutritional knowledge. Twenty-five percent found it difficult to identify patient in need of nutritional therapy, 39% lacked techniques for identifying malnourished patients, and 53% found it difficult to calculate the patients' energy requirement and 66% lacked national guidelines for clinical nutrition. Twenty-eight percent answered that insufficient nutrition practice could lead to complications and prolonged hospital stay. Those that answered that their nutritional knowledge was good had also a better nutritional practice. The self-reported nutritional knowledge was inadequate among Scandinavian doctors and nurses. Increased nutritional knowledge seems to improve the nutritional practice. A combination of an integrated nutrition curriculum during the education, together with post-graduated education for both physicians and nurses should be established.
