The present study examined the impacts of training on nutrition, hygiene and food safety designed by the Nutrition Working Group, Child Survival Collaborations and Resources Group (CORE).

Adapted from the 21d Positive Deviance/Hearth model, mothers were trained on the subjects of appropriate complementary feeding, water, sanitation and hygiene (WASH) practices, and aflatoxin contamination in food. To assess the impacts on child undernutrition, a randomised controlled trial was implemented on a sample of 179 mothers and their children (<2 years old) in two districts of Malawi, namely Mzimba and Balaka.

A 21d intensive learning-by-doing process using the positive deviance approach.

Malawian children and mothers.

Difference-in-difference panel regression analysis revealed that the impacts of the comprehensive training were positive and statistically significant on the Z-scores for wasting and underweight, where the effects increased constantly over time within the 21d time frame. As for stunting, the coefficients were not statistically significant during the 21d programme, although the level of significance started increasing in 2 weeks, indicating that stunting should also be alleviated in a slightly longer time horizon.

The study clearly suggests that comprehensive training immediately guides mothers into improved dietary and hygiene practices, and that improved practices take immediate and progressive effects in ameliorating children’s undernutrition.

To describe seafood consumption patterns in First Nations (FN) in British Columbia (BC) and examine lifestyle characteristics associated with seafood consumption; to identify the top ten most consumed seafood species and their contributions to EPA and DHA intake; and to estimate dietary exposure to methylmercury, polychlorinated biphenyls and dichlorodiphenyldichloroethylene.

Dietary and lifestyle data from the First Nations Food Nutrition and Environment Study, a cross-sectional study of 1103 FN living in twenty-one communities across eight ecozones in BC, Canada, were analysed. Seafood consumption was estimated using a traditional FFQ. Seafood samples were analysed for contaminant contents.

Seafood consumption patterns varied significantly across BC ecozones reflecting geographical diversity of seafood species. The top ten most consumed species represented 64 % of total seafood consumption by weight and contributed 69 % to the total EPA+DHA intake. Mean EPA+DHA intake was 660·5 mg/d in males, 404·3 mg/d in females; and 28 % of FN met the Recommended Intake (RI) of 500 mg/d. Salmon was the most preferred species. Seafood consumption was associated with higher fruit and vegetable consumption, lower smoking rate and increased physical activity. Dietary exposure to selected contaminants from seafood was negligible.

In FN in BC, seafood continues to be an essential part of the contemporary diet. Seafood contributed significantly to reaching the RI for EPA+DHA and was associated with a healthier lifestyle. Given numerous health benefits, seafood should be promoted in FN. Efforts towards sustainability of fishing should be directed to maintain and improve access to fisheries for FN.

Zn deficiency and diarrhoea are prevalent and may coexist in children living in low-resource settings. Recently, a novel approach for delivering Zn via microbiologically treated, Zn-fortified water was shown to be effective in improving Zn status in West African schoolchildren. We assessed the effectiveness of Zn-fortified, microbiologically purified water delivered as a household intervention on Zn intake, status and morbidity in children aged 2–6 years from rural western Kenya.

Randomised controlled trial. Intervention included households assigned to water treatment device with (ZFW) or without (FW) Zn delivery capability

Rural households in Kisumu, western Kenya.

Children aged 2–6 years.

The ZFW group had higher dietary Zn intake compared with the FW group. ZFW contributed 36 and 31 % of daily requirements for absorbable Zn in children aged 2–3 and 4–6 years, respectively, in the ZFW group. Consumption of Zn-fortified water resulted in lower prevalence of reported illness (risk ratio; 95 % CI) in the ZFW group compared with the FW group: for cold with runny nose (0·91; 0·83, 0·99; P=0·034) and abdominal pain (0·70; 0·56, 0·89; P=0·003) in the intention-to-treat analysis and for diarrhoea (0·72; 0·53, 0·96; P=0·025) in the per-protocol analysis. We did not detect an effect of treatment on plasma Zn concentration.

Daily consumption of Zn-fortified, microbiologically treated water results in increased intake of absorbable dietary Zn and may help in preventing childhood infections in pre-school children in rural Africa.

To investigate the association of policy, systems and environmental factors with improvement in household food security among low-income Indiana households with children after a Supplemental Nutrition Assistance Program-Education (SNAP-Ed) direct nutrition education intervention.

Household food security scores measured by the eighteen-item US Household Food Security Survey Module in a longitudinal randomized and controlled SNAP-Ed intervention study conducted from August 2013 to April 2015 were the response variable. Metrics to quantify environmental factors including classification of urban or rural county status; the number of SNAP-authorized stores, food pantries and recreational facilities; average fair market housing rental price; and natural amenity rank were collected from government websites and data sets covering the years 2012–2016 and used as covariates in mixed multiple linear regression modelling.

Thirty-seven Indiana counties, USA, 2012–2016.

SNAP-Ed eligible adults from households with children (n 328).

None of the environmental factors investigated were significantly associated with changes in household food security in this exploratory study.

SNAP-Ed improves food security regardless of urban or rural location or the environmental factors investigated. Expansion of SNAP-Ed in rural areas may support food access among the low-income population and reduce the prevalence of food insecurity in rural compared with urban areas. Further investigation into policy, systems and environmental factors of the Social Ecological Model are warranted to better understand their relationship with direct SNAP-Ed and their impact on diet-related behaviours and food security.

To evaluate the effectiveness of a pilot study of a parental school-based intervention to promote healthy eating behaviours in young children.

A quasi-experimental longitudinal design with three conditions (complete intervention (CIG), minimal intervention (MIG), control (CG)), with repeated measures at baseline, immediately after the intervention, 6 months and 1 year after intervention.

Fourteen public and state-funded kindergartens near Lisbon, Portugal.

Parents (n 349) of 3- to 6-year-old children assigned to the three conditions completed the baseline protocol. The ‘Red Apple’ intervention included four parental group sessions about young children’s growth, nutritional guidelines and positive parental feeding strategies, which was combined with adult–child activities at home and in the classroom, and newsletters (CIG). MIG included only a single nutritional counselling session, whereas the CG had no intervention. At the end, thirty-eight, twenty-six and fifty-four parents in the CIG, MIG and CG, respectively, had completed all evaluation components. Data regarding parental perception of children’s weight, self-efficacy, nutritional knowledge, feeding strategies, eating behaviours and BMI were collected at the four assessment moments.

The CIG showed improvements in children’s healthy food intake, compared with the MIG and CG. Parental self-efficacy regarding the regulation of children’s eating behaviours decreased in the CG but not in both intervention groups.

Considering the low dosage of the intervention, the results obtained were positive. Future studies should offer additional solutions to overcome barriers to parents’ participation.

Increasing evidence documents fathers’ influential role in their children’s eating, physical activity (PA) and sedentary behaviours (SB). We aimed to expand limited existing research examining fathers’ influence in these areas by exploring Latino fathers’ beliefs, attitudes and practices related to eating, PA and SB of their young children.

Seven focus group discussions were conducted in Spanish with Latino fathers (n 28) of children aged 2–8 years. Audio recordings were transcribed and translated verbatim without identifiers. Data were analysed using thematic analysis to identify key concepts and themes using NVivo 11 software.

Fathers expressed positive beliefs and attitudes about the importance of healthy eating for their young children, themselves and their families. Nevertheless, the majority reported familial practices including eating out, getting take-out, etc. that have been linked to increased obesity risk among Latino children. Fathers were more involved and engaged in children’s PA than eating and feeding. However, several fathers reported engaging predominantly in sedentary activities with their children, appeared permissive of children’s sedentary habits and struggled to set limits on children’s screen-time.

We provide new information on Latino fathers’ beliefs and child feeding and PA practices that may provide important targets for interventions aimed at promoting healthful eating and PA behaviours of Latino children. Future research should further quantify the influence of Latino fathers’ parenting styles and practices on development of children’s eating, PA and SB. This information is needed to identify risk factors amenable to interventions and to design culturally appropriate parenting and family-based interventions targeting Latino children’s home environment and designed to meet this ethnic group’s specific needs.

To examine perspectives on food access among low-income families participating in a cost-offset community-supported agriculture (CO-CSA) programme.

Farm Fresh Foods for Healthy Kids (F3HK) is a multicentre randomized intervention trial assessing the effect of CO-CSA on dietary intake and quality among children from low-income families. Focus groups were conducted at the end of the first CO-CSA season. Participants were interviewed about programme experiences, framed by five dimensions of food access: availability, accessibility, affordability, acceptability and accommodation. Transcribed data were coded on these dimensions plus emergent themes.

Nine communities in the US states of New York, North Carolina, Washington and Vermont.

Fifty-three F3HK adults with children.

CSA models were structured by partner farms. Produce quantity was abundant; however, availability was enhanced for participants who were able to select their own produce items. Flexible CSA pick-up times and locations made produce pick-up more accessible. Despite being affordable to most, payment timing was a barrier for some. Unfamiliar foods and quick spoilage hindered acceptability through challenging meal planning, despite accommodations that included preparation advice.

Although CO-CSA may facilitate increased access to fruits and vegetables for low-income families, perceptions of positive diet change may be limited by the ability to incorporate share pick-up into regular travel patterns and meal planning. Food waste concerns may be particularly acute for families with constrained resources. Future research should examine whether CO-CSA with flexible logistics and produce self-selection are sustainable for low-income families and CSA farms.

Food insecurity is reported in approximately 28 % of individuals with diabetes in the USA and is associated with poor glycaemic and lipid control. The present study aimed to understand the direct and indirect pathways through which food insecurity impacts glycaemic control in individuals with diabetes.

Adults (n 615) with type 2 diabetes completed validated questionnaires after recruitment from two primary care clinics. Structural equation modelling was used to investigate mechanisms through which food insecurity influences diabetes self-care behaviours and glycaemic control, including investigation into possible direct and indirect effects of perceived stress and social support.

The final model showed that higher food insecurity was directly significantly related to increased stress (r=0·14, P<0·001) and increased glycosylated Hb (r=0·66, P=0·03). Higher stress was significantly related to poorer self-care (r=−0·54, P<0·001) and lower social support (r=−0·41, P<0·001). There was no significant direct association between food insecurity and self-care, or between perceived stress and glycaemic control.

Food insecurity had both a direct effect on glycaemic control and an indirect effect on self-care through stress. The indirect pathway suggests that efforts to address stress may influence the ability of individuals to perform diabetes self-care behaviours. The direct effect on glycaemic control suggests that pathways independent of self-care behaviours may also be necessary to improve diabetes outcomes. Results from the study suggest a multipronged approach is necessary to address food insecurity in individuals with diabetes.

To determine if voluntary policies on supermarket checkout foods are associated with a difference in the healthfulness of foods displayed at, or near, supermarket checkout areas.

Cross-sectional survey of foods at, or near, supermarket checkouts categorised as less healthy or not according to the Food Standards Agency’s Nutrient Profiling Model.

One city in Eastern England (population about 125 000).

All stores in nine supermarket groups open for business in June–July 2017 in the study city. Supermarket checkout food policies were categorised as clear and consistent, vague or inconsistent, or none.

In thirty-three stores, 11 434 checkout food exposures were recorded, of which 8010 (70·1 %) were less healthy; and 2558 foods in areas near checkouts, of which 1769 (69·2 %) were less healthy. After adjusting for a marker of store size, the odds of a checkout food exposure being ‘less healthy’ was lower in stores with vague or inconsistent checkout policies (OR=0·63; 95 % CI 0·49, 0·80) and in stores with clear and consistent checkout policies (OR=0·33; 95 % CI 0·24, 0·45), compared with no policy. There was no difference in the odds of foods near, but not at, checkouts being less healthy according to checkout food policy.

Supermarket checkout food policies were associated with lower odds of checkout foods but not foods near, but not at, checkouts being less healthy. Further research is required to explore impacts on purchasing and consumption.

To assess the prevalence and sociodemographic determinants of breast-feeding (BF) and exclusive breast-feeding (EBF) in Cyprus up to the sixth month.

Cross-sectional and longitudinal descriptive study. BF and EBF were estimated based on mothers’ self-reported BF status in line with Step 7 of the WHO/UNICEF Baby-Friendly Hospital Initiative questionnaire and based on 24 h recall.

Maternity wards in all public hospitals and twenty-nine (of thirty-five) private maternity clinics nationwide.

Consecutive sample of 586 mothers recruited within 48 h from birth, followed up by telephone interview at the first, fourth and sixth month.

Although 84·3 % of mothers initiated BF before discharge, prevalence of BF at the sixth month was 32·4 %, with the highest reduction observed between the first and fourth months. Prevalence of EBF at 48 h was 18·8 % and fell gradually to 5·0 % at the sixth month. Mothers with higher educational attainment or higher family income were more likely to breast-feed until the sixth month. In terms of EBF, an association was observed only with education, which persisted until the sixth month. Other than social gradient, mode of delivery was the strongest determinant of BF initiation, exclusivity and continuation. Mothers who gave birth vaginally were three to four times more likely to initiate BF (OR=3·1; 95 % CI 1·7, 5·4) and EBF (OR=4·3; 95 % CI 2·7, 6·8).

The low prevalence of BF and EBF in Cyprus, together with the fact that caesarean section rates are currently among the highest in Europe, suggest the need for further research to understand this multidimensional phenomenon and for interdisciplinary policy action to protect, promote and support BF.

To explore awareness and perceptions of the sugar-sweetened beverage (SSB) tax implemented in Mexico in 2014 among a sample of Mexican adolescents, and to investigate how the tax has affected their purchases and intake of SSB.

Qualitative.

Semi-structured interviews were conducted in April–May 2016. The data were analysed using thematic analysis.

Adolescents residing in north-west Mexico (n 29, 55·2 % females), aged 15–19 years.

Four main themes emerged: awareness of taxation; perceptions of how the tax has affected SSB intake; reasons why the tax was not perceived to have affected SSB intake; and preferences for substitution of the taxed SSB. Participants were mostly unaware of the tax and perceived that it would not cause reductions in their intake of SSB; they felt that the price increase was low and insufficient to affect intake. Taste preferences and ‘addiction’ to SSB were highlighted as the main reasons why participants perceived taxation would not affect intake. If SSB prices were to increase further via a higher tax, participants would consider substituting SSB with other beverages, namely home-made drinks (e.g. 100 % fruit juices), non-caloric, instant-flavoured drinks and water.

These findings provide important insights into the views of this sample of Mexican adolescents regarding the taxation of SSB, by pointing out several possible limitations of the tax policy in Mexico. These results could inform the design of future interventions directed at Mexican youth that would complement and strengthen the current SSB taxation.

Community pharmacies could provide access for clients to commercial weight management organizations. We evaluated recruitment, referral and outcomes of adults provided with free vouchers by community pharmacies to attend Scottish Slimmers classes.

Prospective cohort design with qualitative interviews with clients and pharmacy personnel. Scottish Slimmers collected weight and attendance data.

Pharmacies in Aberdeen City, Scotland.

Clients aged ≥18 years with BMI≥30 kg/m2.

Ten of twenty-three pharmacies were recruited; eight successfully recruited clients. Of 129 clients recruited, ninety-seven (75 %) attended at least one class and fifty-one (40 %) attended all twelve classes. At baseline, clients’ mean weight was 99·4 (sd 17·5) kg, mean BMI was 37·8 (sd 6·0) kg/m2. After 12 weeks, mean weight change was −3·7 % (last observation carried forward) or −2·8 % (baseline observation carried forward) for all ninety-seven clients. Client interviews indicated that many individuals would have not addressed their weight problems if this referral service had not been available. They had positive attitudes towards the pharmacy signposting service, attributed to the use of consultation rooms for privacy, receiving professional service from personnel and ongoing support and encouragement. The free provision of 12-week access facilitated participation. Service providers had positive attitudes and indicated their willingness to provide this service in future.

Community pharmacies could be used to increase access to weight management services, with pharmacy personnel providing additional support to clients. Future provision of pharmacy referral schemes should be evaluated on a larger scale with an economic evaluation.

Breast-feeding in the first 6 months of life is critical for ensuring both child health and well-being. Despite efforts to improve breast-feeding practices, recent studies have reported that Myanmar continues to have low rates of exclusive breast-feeding.

A community-based breast-feeding promotion programme using trained community members was implemented for 1 year in hard-to-reach townships of Myanmar. The present study assessed the breast-feeding practices using a cross-sectional survey of 610 mothers of children under 2 years old: specifically, breast-feeding within 24 h, exclusive breast-feeding up to 6 months and breast-feeding duration.

Using Cox models for breast-feeding duration before 24 months, the hazard of breast-feeding cessation was lower in programme v. non-programme townships (hazard ratio (HR)=0·55; 95 % CI 0·32, 0·95). Mothers who worked as shop owners or ran a family business had lower hazard of breast-feeding cessation (HR=0·13, P<0·05) v. those who worked as supervisors, managers, self-employed and businesswomen. The hazard of breast-feeding cessation was higher in women in higher wealth quintiles v. those in the lowest quintile (lower quintile, HR=3·49, P<0·1; higher quintile, HR=3·50, P<0·1; highest quintile, HR=3·47, P<0·1).

The intervention did not affect exclusive breast-feeding practices or breast-feeding within the first 24 h. Potential reasons include existing high levels of early initiation of breast-feeding due to ongoing government-led maternal and child health activities, and social and traditional practices related to complementary feeding. Community-based breast-feeding programmes should continue to promote exclusive breast-feeding and develop strategies to support working mothers.

Increased out-of-pocket health-care expenditures may exert budget pressure on low-income households that leads to food insecurity. The objective of the present study was to examine whether older adults with higher chronic disease burden are at increased risk of food insecurity.

Secondary analysis of the 2013 Health and Retirement Study (HRS) Health Care and Nutrition Study (HCNS) linked to the 2012 nationally representative HRS.

USA.

Respondents of the 2013 HRS HCNS with household incomes <300 % of the federal poverty line (n 3552). Chronic disease burden was categorized by number of concurrent chronic conditions (0–1, 2–4, ≥5 conditions), with multiple chronic conditions (MCC) defined as ≥2 conditions.

The prevalence of food insecurity was 27·8 %. Compared with those having 0–1 conditions, respondents with MCC were significantly more likely to report food insecurity, with the adjusted odds ratio for those with 2–4 conditions being 2·12 (95 % CI 1·45, 3·09) and for those with ≥5 conditions being 3·64 (95 % CI 2·47, 5·37).

A heavy chronic disease burden likely exerts substantial pressure on the household budgets of older adults, creating an increased risk for food insecurity. Given the high prevalence of food insecurity among older adults, screening those with MCC for food insecurity in the clinical setting may be warranted in order to refer to community food resources.

The current study aimed to assess Uruguayan consumers’ accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines.

An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses.

Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts.

Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines.

Children’s poor growth and nutrition status has serious consequences and therefore it is important to understand its contributing factors.

A community-based interventional study focusing on child feeding was conducted in a rural community in China. Data from the intervention group at baseline (1–4 months of age) and follow-up visits (12 and 18 months of age) were used in the present study (n 236). A structural equation model was generated to explore the effects of family wealth, household food safety, dietary intake, diseases and other factors on the growth and nutrition of young children.

Mother’s knowledge and behaviours on household food safety had positive effects on children’s weight-for-age Z-score (WAZ; βdirect=0·03 and 0·15, respectively, at 12 months of age; βdirect=0·02 and 0·08, respectively, at 18 months; P<0·05) and weight-for-length Z-score (WLZ; βdirect=0·04 and 0·21, respectively, at 12 months of age; βdirect=0·01 and 0·06, respectively, at 18 months; P<0·05). While mothers’ feeding behaviours and children’s dietary intake at 12 months of age were positively associated with WAZ and/or WLZ at current and later ages, children’s diseases were negatively associated with WAZ and WLZ cross-sectionally.

Caregiver’s knowledge and feeding behaviours, and children’s dietary intake and diseases, are factors influencing the WAZ and WLZ of children. Promoting feeding and health knowledge and behaviours at early stages of childhood can improve children’s physical growth at later ages.

The physical and social environments that surround children should support good health. However, challenges with food security and access prevent many children from consuming a healthy diet, which is critical to proper growth and development. The present study sought to gain a better understanding of primary care initiatives to address these issues in a low-income setting.

Following the relocation of a paediatric clinic to a farmers’ market building and the implementation of a fruit and vegetable prescription programme, researchers conducted thirty-two semi-structured interviews with caregivers. Researchers elicited caregivers’ perceptions of clinic co-location with the farmers’ market; experiences with the prescription programme; opinions of the farmers’ market; and perceived impact on child consumption of fresh produce. Interview recordings were transcribed for textual analysis. Using thematic analysis, researchers examined qualitative data to identify patterns across transcripts and formulate emerging themes. Researchers concluded when data saturation was reached.

Flint, Michigan, USA.

The majority of participants were female (91 %) and African American (53 %).

Four recurrent themes emerged during interviews: (i) convenience of relocation; (ii) attitude towards prescription programme; (iii) challenges with implementation; and (iv) perceived impact of combined interventions. Caregivers indicated that the co-location and prescription programme increased family shopping at the farmers’ market, improved access to high-quality produce and improved food security.

A fruit and vegetable prescription programme involving a partnership between a farmers’ market and paediatric clinic was perceived as effective in improving food security, food access and child consumption of fresh fruits and vegetables.

High frequency of low birth weight (LBW) is observed in rural compared with urban Indian women. Since maternal BMI is known to be associated with pregnancy outcomes, the present study aimed to investigate factors associated with BMI in early pregnancy of urban and rural South Indian women.

Prospective observational cohort.

A hospital-based study conducted at an urban and a rural health centre in Karnataka State.

Pregnant women (n 843) aged 18–40 years recruited in early pregnancy from whom detailed sociodemographic, environmental, anthropometric and dietary intake information was collected.

A high proportion of low BMI (32 v. 26 %, P<0·000) and anaemia (48 v. 23 %, P<0·000) was observed in the rural v. the urban cohort. Rural women were younger, had lower body weight, tended to be shorter and less educated. They lived in poor housing conditions, had less access to piped water and good sanitation, used unrefined fuel for cooking and had lower standard of living score. The age (β=0·21, 95 % CI 0·14, 0·29), education level of their spouse (β=1·36, 95 % CI 0·71, 2·71) and fat intake (β=1·24, 95 % CI 0·20, 2·28) were positively associated with BMI in urban women.

Our findings indicate that risk factors associated with BMI in early pregnancy are different in rural and urban settings. It is important to study population-specific risk factors in relation to perinatal health.
