Xu YY, Sawadogo-Lewis T, King SE, Mitchell A, Roberton T. Integrating nutrition into the education sector in low- and middle-income countries: A framework for a win-win collaboration. MATERNAL AND CHILD NUTRITION 2021; 17:e13156. [PMID: 33590645 PMCID: PMC8189246 DOI: 10.1111/mcn.13156] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 12/14/2020] [Accepted: 01/20/2021] [Indexed: 12/01/2022]
Abstract
Malnutrition—both undernutrition and overnutrition—is a public health concern worldwide and particularly in low‐ and middle‐income countries (LMICs). The education sector has high potential to improve immediate nutrition outcomes by providing food in schools and to have more long‐term impact through education. We developed a conceptual framework to show how the education sector can be leveraged for nutrition. We reviewed the literature to identify existing frameworks outlining how nutrition programs can be delivered by and through the education sector and used these to build a comprehensive framework. We first organized nutrition programs in the education sector into (1) school food, meals, and food environment; (2) nutrition and health education; (3) physical activity and education; (4) school health services; and (5) water, sanitation, and hygiene (WASH) sector. We then discuss how each one can be successfully implemented. We found high potential in improving nutrition standards and quality of school foods, meals and food environment, especially through collaboration with the agriculture sector. There is a need for well‐integrated, culturally appropriate nutrition and health education into the existing school curriculum. This must be supported by a skilled workforce—including nutrition and public health professionals and school staff. Parental and community engagement is cornerstone for program sustainability and success. Current monitoring and evaluation of nutrition programming in schools is weak, and effectiveness, including cost‐effectiveness, of interventions is not yet adequately quantified. Finally, we note that opportunities for leveraging the education sector in the fight against rising overweight and obesity rates are under‐researched and likely underutilized in LMICs.

Association of Polychlorinated Biphenyls and Organochlorine Pesticides with Autism Spectrum Disorder in Jamaican Children. RESEARCH IN AUTISM SPECTRUM DISORDERS 2020; 76:101587.

Abstract
BACKGROUND Polychlorinated biphenyls (PCBs) and organochlorine (OC) pesticides are suspected to play a role in autism spectrum disorder (ASD). OBJECTIVES To investigate associations of PCBs and OC pesticides with ASD in Jamaican children and explore possible interaction between PCBs or OC pesticides with glutathione S-transferase (GST) genes (GSTT1, GSTM1, GSTP1) in relation to ASD. METHODS Participants included n=169 age- and sex-matched case-control pairs of Jamaican children 2-8 years old. Socioeconomic status and food frequency data were self-reported by the parents/guardians. Blood from each participant was analyzed for 100 PCB congeners and 17 OC pesticides and genotyped for three GST genes. PCBs and OC pesticides concentrations below the limit of detection (LoD) were replaced with (LoD/√2). We used conditional logistic regression (CLR) models to assess associations of PCBs and OC pesticides with ASD, individually or interactively with GST genes (GSTT1, GSTM1, GSTP1). RESULTS We found inverse associations of PCB-153 [adjusted MOR (95% CI) = 0.44 (0.23-0.86)] and PCB-180 [adjusted MOR (95% CI) = 0.52 (0.28-0.95)] with ASD. When adjusted for covariates in a CLR the interaction between GSTM1 and PCB-153 became significant (P < 0.01). DISCUSSION Differences in diet between ASD and typically developing control groups may play a role in the observed findings of lower concentrations of PCB-153 and PCB-180 in individuals with ASD than in controls. Considering the limited sample size and high proportion of concentrations below the LoD, these results should be interpreted with caution but warrant further investigation into associations of PCBs and OC pesticides with ASD.

Altink H. Tackling child malnutrition in Jamaica, 1962-2020. HUMANITIES & SOCIAL SCIENCES COMMUNICATIONS 2020; 7:50. [PMID: 33474556 PMCID: PMC7116602 DOI: 10.1057/s41599-020-00536-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/05/2020] [Accepted: 06/30/2020] [Indexed: 06/12/2023]
Abstract
On the eve of independence in 1962, malnutrition was the largest single cause of death in Jamaica for children under one. Although child malnutrition rates have rapidly declined since 1962, today Jamaica experiences a double burden of malnutrition: the coexistence of pockets of high child malnutrition with rising levels of childhood obesity. Based on a wide range of sources, including public documents, newspaper reports, scientific studies and reports by international agencies, this article examines a gradual decline in child malnutrition and the rise of the double burden of malnutrition in Jamaica from independence to the present. It will first of all show that changes in the global economy and overseas loans and aid both aided and limited the ability of the Jamaican government to lower child malnutrition levels and also contributed to a rise in childhood obesity. Second, it will illustrate that a traditional deficit-led approach to child malnutrition was followed in post-independent Jamaica, focussing on the public and individuals as targets for intervention and using quantitative measures to trace progress. And third, it will question whether the double burden of child malnutrition will give rise to 'healthy publics'-'dynamic collectives of people, ideas and environments that can enable health and well-being'.

Abstract
Without gains in nutritional outcomes, it is unlikely that school feeding programmes (SFP) could improve cognition and academic performance of schoolchildren despite the improvements in school enrolment. We compared the nutrient intake adequacy and Fe and nutritional status of SFP and non-SFP participants in a cross-sectional survey involving 383 schoolchildren (aged 5-13 years). Quantitative 24 h recalls and weighed food records, repeated in 20% subsample, were used to estimate energy and nutrient intakes adjusted for day-to-day variations. The probability of adequacy (PA) was calculated for selected micronutrients and the mean of all PA (MPA) was calculated. The concentrations of Hb, serum ferritin, and soluble transferrin receptor (sTfR) and anthropometric measurements were used to determine Fe and nutritional status. Energy and nutrient intakes and their adequacies were significantly higher among SFP participants (P<0·001). The MPA of micronutrients was significantly higher among SFP participants (0·61 v. 0·18; P<0·001), and the multiple-micronutrient-fortified corn soya blend was a key contributor to micronutrient adequacy. In SFP participants, 6 g/l higher Hb concentrations (P<0·001) and about 10% points lower anaemia prevalence (P=0·06) were observed. The concentration of sTfR was significantly lower among SFP participants (11·2 v. 124 mg/l; P=0·04); however, there was no difference in the prevalence of Fe deficiency and Fe-deficiency anaemia between SFP and non-SFP participants. There was also no significant difference in the prevalence of thinness, underweight and stunting. In conclusion, the present results indicate that school feeding is associated with higher intakes and adequacies of energy and nutrients, but not with the prevalence of Fe and nutritional status indicators. The results also indicate an important role for micronutrient-dense foods in the achievement of micronutrient adequacy within SFP.

Abstract
Background To reverse the trend of rising child obesity rates in many middle-income countries, recommendations include increasing fruit and vegetable consumption. Schools can positively impact children's eating behavior, and multicomponent interventions that include the curriculum, school food environments, and parental involvement are most effective. Objective To find out how fruits and vegetables feature in the dietary guidelines provided to schools, what specific schemes are available for providing these foods, the extent to which nutrition education is included in the curriculum, and how vegetables and fruits are procured in primary schools. Methods In 2008, a survey questionnaire previously validated and revised was sent electronically to national program managers and focal points for school feeding programs in 58 middle-income countries. The rationale was to obtain information relevant to the entire country from these key informants. The survey response rate was 46%. The information provided by 22 respondents in 18 countries was included in the current study. On average, respondents answered 88% of the questions analyzed in this paper. Of the respondents, 73% worked for the national authority responsible for school food programs, with 45% at the program coordinator or director level. Results Few countries have any special fruit and vegetable schemes; implementation constraints include cost and lack of storage facilities. Although 11 of 18 countries have both nutrient-based guidelines and school food guidelines for meals, fruits and vegetables are often not adequately specified. Conclusions In some countries, nutrition education, special activities, school gardens, and parental participation are used to promote fruits and vegetables. Specific schemes are needed in some, together with school food guidelines that include fruits and vegetables.

Abstract
BACKGROUND This study evaluated whether food insecurity and obesity were associated in a population sample in Trinidad. METHODS A sample was drawn of 15 clusters of households, in north central Trinidad. Resident adults were enumerated. A questionnaire was administered including the short form Household Food Security Scale (HFSS). Heights and weights were measured. Analyses were adjusted for age, sex, and ethnic group. RESULTS Data were analysed for 531/631 (84%) of eligible respondents including 241 men and 290 women with a mean age of 47 (range 24-89) years. Overall, 134 (25%) of subjects were classified as food insecure. Food insecurity was associated with lower household incomes and physical disability. Food insecure subjects were less likely to eat fruit (food insecure 40%, food secure 55%; adjusted odds ratio [OR] = 0.60, 95% CI: 0.36-0.99, P = 0.045) or green vegetables or salads (food insecure 28%, food secure 51%; adjusted OR = 0.46, 95% CI: 0.27-0.79, P = 0.005) on >/=5-6 days per week. Body mass index (BMI) was available for 467 (74%) subjects of whom 41 (9%) had BMI <20 kg/m(2), 157 (34%) had BMI 25-29 kg/m(2), and 120 (26%) had BMI >/=30 kg/m(2). Underweight (OR = 3.21, 95% CI: 1.17-8.81) was associated with food insecurity, but obesity was not (OR = 1.08, 95% CI: 0.55-2.12). CONCLUSIONS Food insecurity was frequent at all levels of BMI and was associated with lower consumption of fruit and vegetables. Food insecurity was associated with underweight but not with present obesity.

Abstract
OBJECTIVE To evaluate the provision of free school meals in Trinidad and Tobago in relation to children's social and nutritional status. DESIGN AND METHODS Cross-sectional survey of a nationally representative sample of 66 government schools, including children in the admissions classes (aged 4 to 7 years) and classes for 'rising nines' (aged 7-10 years). Data included questionnaire details of free school meals and children's social background, and measurements of children's heights, weights and skinfold thicknesses. RESULTS Of 6731 eligible children, data were analysed for 5688 (85%). There were 2386 (42%) children receiving free meals provided at school. At different schools the proportion of all children receiving free meals ranged from 20% to 100%, Receipt of free meals was associated with larger family size (one child, 32% received free meals; > or =6 children, 63%), lower paternal educational attainment (primary, 52% free; university, 30%), father's employment (employed, 39% free meals; unemployed >12 months, 59%) as well as maternal education and employment and household amenities. After adjusting for age, sex and ethnic group, children who received free meals were shorter (mean difference in height standard deviation score (SDS) -0.12, 95% confidence interval (CI) -0.17 to -0.06), lighter (body mass index SDS -0.21, -0.28 to -0.14) and thinner (subscapular skinfold SDS -0.13, -0.18 to -0.09). CONCLUSIONS Free school meals were widely available, with some targeting of provision to children with less favourable social and nutritional status. Greater universality would reduce inequity, but more stringent targeting and reduction of school-level variation would increase efficiency.
