Abstract
The enormous burden of diet-related chronic diseases has prompted interest in healthy food prescription programs. Yet, the impact of such programs remains unclear. The aim of this study was to conduct a systematic review of healthy food prescription programs and evaluate their impact on dietary behavior and cardiometabolic parameters by meta-analysis. A systematic search was carried out in Medline, Embase, Scopus, and Cochrane Central Register of Controlled Trials databases since their inception to 3 January, 2020 without language restriction. A systematic search of interventional studies investigating the effect of healthy food prescription on diet quality and/or cardiometabolic risk factors including BMI, systolic (SBP) and diastolic blood pressure (DBP), glycated hemoglobin (HbA1c), or blood lipids was carried out. Thirteen studies were identified for inclusion, most of which were quasi-experimental (pre/post) interventions without a control group (n = 9). Pooled estimates revealed a 22% (95% CI: 12, 32; n = 5 studies, n = 1039 participants; I2 = 97%) increase in fruit and vegetable consumption, corresponding to 0.8 higher daily servings (95% CI: 0.2, 1.4; I2 = 96%). BMI decreased by 0.6 kg/m2 (95% CI: 0.2, 1.1; I2 = 6.4%) and HbA1c by 0.8% (95% CI: 0.1, 1.6; I2 = 92%). No significant change was observed in other cardiometabolic parameters. These findings should be interpreted with caution in light of considerable heterogeneity, methodological limitations of the included studies, and moderate to very low certainty of evidence. Our results support the need for well-designed, large, randomized controlled trials in various settings to further establish the efficacy of healthy food prescription programs on diet quality and cardiometabolic health.

Effectiveness of Community Nutrition-Specific Interventions on Improving Malnutrition of Children under 5 Years of Age in the Eastern Mediterranean Region: A Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18157844. [PMID: 34360137 PMCID: PMC8345722 DOI: 10.3390/ijerph18157844] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 07/12/2021] [Accepted: 07/14/2021] [Indexed: 11/16/2022]
Abstract
Childhood malnutrition remains an important public health and development problem in low- and middle-income countries. This study aimed to systematically review the community-based nutrition-specific interventions and their effectiveness and/or cost-effectiveness on the nutritional status of children under 5 years of age in the Eastern Mediterranean Region (EMR). A systematic literature search of the English electronic databases, including PubMed, Scopus, ISI Web of Knowledge, Ovid, EMBASE, as well as Persian databases (SID and Magiran) was performed up to May 2019. Studies regarding the effectiveness/cost-effectiveness of the community-based nutrition-specific programs and interventions targeted at under-five-year children in EMR countries were selected. The primary outcomes were mean of Weight-for-age z-score (WAZ), Height-for-Age z-score (HAZ), and Weight-for-Height z-score (WHZ) of children or prevalence of wasting, stunting, and/or underweight among the children. Meta-analysis was also performed on the selected articles and intervention effects (mean differences) were calculated for each outcome for each study and pooled using a weighted random effects model. Risk of bias (ROB) of each included study was assessed based on the Cochrane Handbook for Systematic Reviews. The study protocol was registered in PROSPERO (CRD42020172643). Of 1036 identified studies, eight met the inclusion criteria. Amongst these, seven were from Pakistan and one from Iran. Only one study conducted in Pakistan reported the cost-effectiveness of nutrition-specific interventions in the region. Nutrition education/consultation and cash-based interventions were the most common nutrition-specific strategies used for management of child malnutrition in the EMR countries. Out of these eight studies, four were included in the meta-analysis. When different interventions were pooled, they had resulted in a significant improvement in WHZ of children (MD: 0.26; 95% CI: 0.07 to 0.46, three studies, I2 82.40%). Considering the high prevalence of child malnutrition in a number of countries in the region, capacity building and investigation regarding the implementation of new approaches to improve nutritional status of children and their effect(s) and cost-effectiveness assessment are highly recommended.

PLoS One 2021; 16:e0248637. [PMID: 33765094 PMCID: PMC7993805 DOI: 10.1371/journal.pone.0248637] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2020] [Accepted: 03/01/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Childhood undernutrition is the leading cause of under-five mortality and morbidity in the world particularly in East African countries. Although there are studies on child undernutrition in different East African countries, our search of the literature revealed that there is limited evidence of a pooled analysis of these studies. Therefore, this study aimed to investigate the pooled prevalence and associated factors of chronic undernutrition (i.e. stunting) among under-five children in East Africa. METHODS A pooled analysis of the Demographic and Health Surveys (DHSs) in 12 East African countries was conducted. A total weighted sample of 79744 under-five children was included in the study. Mixed-effect logistic regression analysis was used to identify significant factors associated with chronic undernutrition since the DHS data has a hierarchical structure. The intra-class correlation coefficient (ICC), Median Odds Ratio (MOR), Likelihood Ratio (LR)-test, and deviance was used for model comparison. Variables with p-value <0.2 in the bivariable mixed-effect logistic regression analysis were considered for the multivariable analysis. In the multivariable multilevel analysis model, the Adjusted Odds Ratio (AOR) with the 95% Confidence Interval (CI) were reported for significant factors. RESULTS The pooled prevalence of chronic undernutrition among underfive children in East Africa was 33.3% (95% CI: 32.9%, 35.6%) ranging from 21.9% in Kenya to 53% in Burundi. Children whose mothers lived in rural area (AOR = 1.11, 95% CI: 1.06, 1.16), born to mother who had no formal education (AOR = 1.42, 95% CI: 1.34, 1.50) and primary education (AOR = 1.37, 95% CI: 1.31, 1.44), being in poor household (AOR = 1.66, 95% CI: 1.58, 1.74), and middle household (AOR = 1.42, 95% CI: 1.35, 1.49), child aged 36-48 months (AOR = 1.09, 95% CI: 1.04, 1.14), being male (AOR = 1.19, 95% CI: 1.15, 1.23), 2nd - 4th birth order (AOR = 1.08, 95% CI: 1.03, 1.13), and above 4th 1.27 (AOR = 1.27, 95% CI: 1.19, 1.35), home delivery 1.09 (AOR = 1.09, 95% CI: 1.05, 1.13), small size at birth (AOR = 1.35, 95% CI: 1.29, 1.40) and being multiple births (AOR = 1.98, 95% CI: 1.81, 2.17) were associated with increased odds of stunting. While, antenatal care visit (AOR = 0.89, 95% CI: 0.86, 0.93), mothers aged 25-34 (AOR = 0.83, 95% CI: 0.79, 0.86) and ≥ 35 years (AOR = 0.76, 95% CI: 0.72, 0.81), large size at birth (AOR = 0.85, 95% CI: 0.81, 0.88), and family size >8 (AOR = 0.92, 95% CI: 0.87, 0.98) were associated with decreased odds of stunting. CONCLUSION The study revealed that stunting among under-five children remains a major public health problem in East Africa. Therefore, to improve child nutrition status the governmental and non-governmental organizations should design public health interventions targeting rural residents, and the poorest households. Furthermore, enhancing health facility delivery, ANC visit, and maternal health education is vital for reducing child chronic undernutrition.

Abstract
Nutrition interventions that target mothers alone inadequately address women's needs across their lives: during adolescence, preconception, and in later years of life. They also fail to capture nulliparous women. The extent to which nutrition interventions effectively reach women throughout the life course is not well documented. In this comprehensive narrative review, we summarized the impact and delivery platforms of nutrition-specific and nutrition-sensitive interventions targeting adolescent girls, women of reproductive age (nonpregnant, nonlactating), pregnant and lactating women, women with young children <5 y, and older women, with a focus on nutrition interventions delivered in low- and middle-income countries. We found that although there were many effective interventions that targeted women's nutrition, they largely targeted women who were pregnant and lactating or with young children. There were major gaps in the targeting of interventions to older women. For the delivery platforms, community-based settings, compared with facility-based settings, more equitably reached women across the life course, including adolescents, women of reproductive age, and older women. Nutrition-sensitive approaches were more often delivered in community-based settings; however, the evidence of their impact on women's nutritional outcomes was less clear. We also found major research and programming gaps relative to targeting overweight, obesity, and noncommunicable disease. We conclude that focused efforts on women during pregnancy and in the first couple of years postpartum fail to address the interrelation and compounding nature of nutritional disadvantages that are perpetuated across many women's lives. In order for policies and interventions to more effectively address inequities faced by women, and not only women as mothers, it is essential that they reflect on how, when, and where to engage with women across the life course.

Abstract
OBJECTIVE To evaluate the process of implementation of a national nutritional programme for improving the nutritional status of children in Iran. DESIGN A cross-sectional process evaluation was carried out using field observations, document reviews, semi-structured interviews and focus group discussions. SETTING Data were collected across urban and rural areas of Qazvin and Semnan provinces of Iran, March-September 2014. SUBJECTS Mothers (n 362) of children under programme coverage were chosen for the survey. Senior nutrition officers, the head of Hygiene, Remedy and Insurance Affairs at Imam Khomeini Relief Foundation and community health workers were selected purposively for interviews. Mothers with at least one child under 6 years of age covered by the programme were selected to participate in focus group discussions. RESULTS Five steps of programme implementation were identified: supplementary food basket content, food basket distribution methods, selection of eligible children, distributed food consumption, and child growth monitoring and nutrition training sessions for mothers. The distributed food baskets did not have enough milk/dairy products, vegetables and fruits. Nearly 50 % of children consumed 75-100 % of the distributed milk and cake/biscuit, while staple foods were shared with other family members. When electronic cards were offered instead of food baskets, attendance for child growth monitoring and the food items participants chose with the cards tended to differ from what was originally designed. CONCLUSIONS Focusing on food items that are mostly being used for child feeding (e.g. eggs or milk in food baskets) may be beneficial to assure the target child is receiving the distributed foods.

Abstract
This study aimed to evaluate the effectiveness of the national food distribution program on the growth and nutritional status of malnourished or growth-retarded children in 2 provinces of Iran. A quasi-experimental design was used for the effectiveness evaluation. Qualitative data were gathered to explain the results. An intervention group consisted of 362 children aged 6-72 months who were under coverage of the program. These children received monthly food as foodstuff, food vouchers, or cash. A comparison group included 409 children aged 6-72 months who were selected from those covered by the Primary Health Care system. Children anthropometric indices were measured at the baseline and also 6 months later. Twelve focus group discussions were held with mothers who had at least 1 child under the coverage of the program. At the end of the study, the mean weight-for-age Z scores, height-for-age Z scores, and weight-for-height Z scores increased compared with the baselines in both groups (p < .001). The differences between 2 groups in weight-for-age Z scores, height-for-age Z scores, and weight-for-height Z scores were not significant at the end of the study (p = .62, p = .91, and p = .94, respectively). According to the mothers' reports, factors affected the program outcome, that is, children anthropometric indices were low income, intrahousehold food sharing, irregular distribution, quantity and quality of the distributed food, and insufficient training. Providing foods for the malnourished children living in low-income families helped to prevent a worsening of their nutritional status; however, it has not been effective in solving the problem, probably due to the weak implementation and lack of empowerment strategies.
