RESUMO
Background: Nutritional counseling, which includes two-way interactive education, has been hypothesized to improve the health and nutritional status of pregnant women, but little is known about the impact such practice of care might have on maternal and infant health and behavioral outcomes of pregnant women living in low income, low-middle income, and upper-middle-income countries (LMIC)s. Objectives: We conducted a systematic review to appraise the effectiveness and impact on health equity of two-way nutritional counseling practices in LMICs on maternal and infant behavioral, nutritional, and health outcomes. Search Methods: We conducted electronic searches for relevant studies on Medline, Embase, CINAHL, PsychInfo, and the Cochrane CENTRAL for randomized and non-randomized trials on the effectiveness of two-way interactive nutritional counseling among pregnant women from the date of database inception up to June 22, 2021. In addition, we searched references of included studies in systematic reviews, gray literature resources, and unpublished studies or reports that satisfied our eligibility criteria using a focused Google search. Selection Criteria: We included randomized and non-randomized controlled studies (NRS), controlled before and after, and interrupted time series that assessed the effectiveness of two-way interactive nutrition counseling targeting pregnant women in LMICs. Data Collection and Analysis: Data extraction and risk of bias were conducted in duplicate. The risk of bias (ROB) for randomized trials (RCT) was assessed according to the Cochrane Handbook of Systematic Reviews, and ROB for NRS was assessed using the Newcastle-Ottawa scale (NOS). RCT and NRS were meta-analyzed separately. Main Results: Our search identified 6418 records and 52 studies met our inclusion criteria, but only 28 were used in the quantitative analysis. Twenty-eight studies were conducted in Asia, the most in Iran. Eight studies were conducted in Africa. Two-way interactive nutritional counseling during pregnancy may improve dietary caloric intake (mean difference [MD]: 81.65 calories, 95% confidence interval [CI], 15.37-147.93, three RCTs; I 2 = 42%; moderate certainty of evidence using GRADE assessment), may reduce hemorrhage (relative risk [RR]: 0.63; 95% CI, 0.25-1.54, two RCTs; I 2 = 40%; very low certainty of evidence using GRADE assessment), may improve protein (MD: 10.44 g, 95% CI, 1.83-19.05, two RCTs; I 2 = 95%; high certainty of evidence using GRADE assessment), fat intake (MD: 3.42 g, 95% CI, -0.20 to 7.04, two RCTs; I 2 = 0%; high certainty of evidence using GRADE assessment), and may improve gestational weight gain within recommendations (RR: 1.84; 95% CI, 1.10-3.09, three RCTs; I 2 = 69%). Nutrition counseling probably leads to the initiation of breastfeeding immediately after birth (RR: 1.72; 95% CI, 1.42-2.09, one RCT). There was little to no effect on reducing anemia (RR: 0.77; 95% CI, 0.50-1.20, three RCTs; I 2 = 67%; very low certainty of evidence using GRADE assessment) risk of stillbirths (RR: 0.81; 95% CI, 0.52-1.27, three RCTs; I 2 = 0%; moderate certainty of evidence using GRADE assessment) and risk of cesarean section delivery (RR: 0.96; 95% CI, 0.76-1.20, four RCTs; I 2 = 36%; moderate certainty of evidence using GRADE assessment). Authors' Conclusions: Our review highlights improvements in maternal behavioral and health outcomes through interactive nutrition counseling during pregnancy. However, we are uncertain about the effects of nutrition counseling due to the low certainty of evidence and a low number of studies for some key outcomes. Moreover, the effects on health equity remain unknown. More methodologically rigorous trials that focus on a precise selection of outcomes driven by the theory of change of nutrition counseling to improve maternal and infant behavioral and health outcomes and consider equity are required.
RESUMO
BACKGROUND: To improve nutritional knowledge and attitudes of girls and young women, Nutrition International (NI) partnered with the World Association of Girl Guides and Girl Scouts (WAGGGS) to pilot the Girl-Powered Nutrition (GPN) program from 2018 to 2020 in 4 countries (Madagascar, the Philippines, Sri Lanka, and Tanzania). OBJECTIVE: The aim was to share adolescent girls' and programmers' experiences with co-designing and implementing the GPN program in low- and middle-income countries (LMICs). METHODS: A formative evaluation of the GPN program was commissioned by NI and undertaken by Universalia Management Group (Universalia). The evaluation was largely qualitative (employing focus groups, interviews, and document analysis). Based on the results of the formative evaluation, themes related to working with adolescent girls were identified. RESULTS: The involvement of adolescents in the design, implementation, and evaluation of nutrition programming that targets them is essential for meaningful uptake. Sufficient time and respect must be given to the co-design process, including clearly defining adolescents' roles, ensuring transparency and clear communication, and managing adolescents' expectations. Ensuring adequate exposure and suitable timing for adolescent nutrition programming from adequately trained staff were identified as good practices from the evaluation. Program curriculum and activities must be appropriately tailored to adolescent age and stage, target adolescents and their gatekeepers and duty-bearers, and address the underlying issues of poverty, gender inequality, and structural norms that negatively impact adolescents' agency and nutrition. CONCLUSIONS: This research supports and elaborates on several documented and accepted good practices for working with adolescents to improve nutrition knowledge and attitudes. Similar programs with key features such as co-design, suitable timing, curriculum, and exposure of programs by age group, addressing underlying structural issues, the involvement of gatekeepers and duty-bearers, and confidence-building can increase adolescent girls' nutrition knowledge and attitudes.
RESUMO
The nutritional status of women before pregnancy, during pregnancy, and after delivery has far reaching consequences for maternal health and child survival, growth, and development. In South Asia, the high prevalence of short stature, thinness, and anaemia among women of reproductive age underlie the high prevalence of child undernutrition in the region, whereas overweight and obesity are rising concerns. A systematic review of evidence (2000-2017) was conducted to identify barriers and programme approaches to improving the coverage of maternal nutrition interventions in the region. The search strategy used 13 electronic bibliographic databases and 14 websites of development and technical agencies and identified 2,247 citations. Nine studies conducted in Bangladesh (n = 2), India (n = 5), Nepal (n = 1), and Pakistan (n = 1) were selected for the review, and outcomes included the receipt and consumption of iron and folic acid and calcium supplements and the receipt of information on dietary intake during pregnancy. The studies indicate that a range of barriers acting at the individual (maternal), household, and health service delivery levels affects intervention coverage during pregnancy. Programme approaches that were effective in improving intervention coverage addressed barriers at multiple levels and had several common features: use of formative research and client assessments to inform the design of programme approaches and actions; community-based delivery platforms to increase access to services; engagement of family members, as well as pregnant women, in influencing behavioural change; actions to improve the capacity, supervision, monitoring, and motivation of front-line service providers to provide information and counselling; and access to free supplements.
