To examine trends from 2015 to 2017 in dietary behaviours and diet quality among low-income mothers, teenagers and children.
Design:
Cross-sectional telephone surveys using a validated 24 h dietary assessment.
Setting:
Randomly sampled households with incomes ≤185 % of the US federal poverty level across California.
Participants:
Survey participants were 13 247 mothers (≥18 years), 3293 teenagers (12–17 years) and 6043 children (5–11 years). Respondents were mostly Latino.
Results:
Over the 3-year study period, consumption of fruits and vegetables with and without 100 % fruit juice increased (P ≤ 0·05) by at least 0·3 cups/d for mothers, teenagers and children. Intake of water also increased (P ≤ 0·001) by more than 1 cup/d for mothers and children and 2 cups/d for teenagers. Sugar-sweetened beverage (SSB) consumption was unchanged over the 3 years. Overall diet quality, as assessed by the Healthy Eating Index-2015, improved (P ≤ 0·01) for mothers, teenagers and children. Covariates for the fifteen regression models (three age groups by five outcome variables) included race/ethnicity, age, education for mothers, and gender for teenagers and children.
Conclusions:
The observed increases in fruit and vegetable intake and improvements in overall diet quality during the 3-year period suggest that low-income Californians may have lowered their risk of preventable diseases. However, more intense or strategic SSB-reduction interventions are required. Regional- or state-level, population-based surveillance of dietary behaviours is useful for public health nutrition policy and programme decision making, and can be used to assess potential trends in future negative health outcomes and related costs associated with poor dietary behaviours within at-risk populations.
The purpose of this study was to analyse the reliability and validity of a semi-quantitative FFQ to assess food group consumption in South American children and adolescents.
Design:
The SAYCARE (South American Youth/Child cARdiovascular and Environmental) study is an observational, multicentre, feasibility study performed in a sample of 3- to 18-year-old children and adolescents attending private and public schools from six South American countries. Participants answered the FFQ twice with a two-week interval and three 24-h dietary recalls. Intraclass and Spearman’s correlations, weighted Cohen’s kappa (κw), percentage of agreement and energy-adjusted Pearson’s correlation coefficients were calculated.
Setting:
Seven cities in South America (Buenos Aires, Lima, Medelin, Montevideo, Santiago, Sao Paulo and Teresina).
Subjects:
A sample of 200 children and 244 adolescents for reliability analyses and 252 children and 244 adolescents for validity analyses were included.
Results:
Depending on the food group, for children and adolescents, reliability analyses resulted in Spearman’s coefficients from 0·47 to 0·73, intraclass correlation coefficients from 0·66 to 0·99, κw coefficients from 0·35 to 0·63, and percentage of agreement between 72·75 and 83·52 %. In the same way, validity analyses resulted in Spearman’s coefficients from 0·17 to 0·37, energy-adjusted Pearson’s coefficients from 0·17 to 0·61, κw coefficients from 0·09 to 0·24, and percentages of agreement between 45·79 and 67·06 %.
Conclusion:
The SAYCARE FFQ achieved reasonable reliability and slight-moderate validity for almost all food groups intakes. Accordingly, it can be used for the purpose of ranking the intake of individuals within a population.
Sugar-sweetened beverage (SSB) consumption in early childhood is a public health concern. Adequate hydration in early childhood is also important. We developed a national research agenda to improve beverage consumption patterns among 0–5-year-olds. This article focuses on the process used to develop this research agenda.
Design:
A mixed methods, multi-step process was used to develop the research agenda, including: (i) a scientific advisory committee; (ii) systematic reviews on strategies to reduce SSB consumption and increase water access and consumption; (iii) two stakeholder surveys to first identify and then rank strategies to reduce SSB consumption and increase water access and consumption; (iv) key informant interviews to better understand determinants of beverage consumption and strategies to improve beverage consumption patterns among high-risk groups; (v) an in-person convening with experts; and (vi) developing the final research agenda.
Setting:
This process included research and stakeholders from across the United States.
Participants:
A total of 276 participants completed survey 1 and 182 participants completed survey 2. Key informant interviews were conducted with 12 stakeholders. Thirty experts attended the convening, representing academia, government, and non-profit sectors.
Results:
Thirteen key issue areas and 59 research questions were developed. Priority topics were beverage consumption recommendations, fruit-flavoured drink consumption, interventions tailored to high-risk groups, and family engagement in childcare.
Conclusions:
This research agenda lays the groundwork for research efforts to improve beverage patterns of young children. The methods used can be a template to develop research agendas for other public health issues.
The present study aimed to evaluate the validity and reproducibility of a thirteen-item FFQ regarding identification of dietary conditions in a rural population in China.
Design:
A reproducibility study repeated the first FFQ (FFQ1) approximately 4 weeks later (FFQ2). A validity study evaluated the mean of three consecutive 24 h diet recalls as the reference measure.
Setting:
Cross-sectional study.
Participants:
Residents of a rural area in Henan Province, which is located in the central region of China.
Results:
A total of 295 individuals participated in the reproducibility study. In addition, 123 people agreed to participate in the validity study. Spearman’s correlation coefficients between the two FFQ ranged from 0·06 (vegetables) to 0·58 (eggs). Spearman’s correlation coefficients between the two methods of collection ranged from 0·01 for cereal to 0·49 for staple foods. The mean of the intraclass correlation coefficients of the two FFQ (FFQ1 v. FFQ2) was 0·19. Bland–Altman analysis indicated good agreement for most food groups across the range of intake for the two studies.
Conclusions:
The study demonstrated that our FFQ design could be used as a representative tool to conduct a dietary evaluation of a rural population.
To investigate the nutrition education provided by primary-care physicians (PCP).
Design:
An integrative review was used to examine literature on nutrition care provided by PCP from 2012 to 2018. A literature search was conducted in MEDLINE, PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Scopus using key search terms.
Setting:
USA, Netherlands, Germany, Denmark, UK, Lebanon, Australia and New Zealand.
Participants:
Primary-care physicians.
Results:
Sixteen qualitative and quantitative studies were analysed thematically using meta-synthesis informed by the COM-B model of behaviour (capability, motivation and opportunity), to understand the influences on PCP behaviours to provide nutrition care. PCP perceive that they lack nutrition capability. While PCP motivation to provide nutrition care differs based on patient characteristics and those of their own, opportunity is influenced by medical educators, mentors and policy generated by professional and governmental organisations.
Conclusions:
The development of PCP capability, motivation and opportunity to provide nutrition care should begin in undergraduate medical training, and continue into PCP training, to create synergy between these behaviours for PCP to become confident providing nutrition care as an integral component of disease prevention and management in contemporary medical practice.
Consumption of fruits and vegetables (F&V) among adolescents falls below recommendations in many Western countries. The impact of social and emotional aspects of family life on adolescent dietary behaviour may contribute to this, yet remains under-investigated. The present study examines the association between adolescents’ perceptions of emotional home atmosphere (EHA) and their F&V consumption frequency.
Design:
An FFQ was used to assess F&V consumption frequency. EHA was assessed by an eight-item measure with three subscales: perceived home warmth, strictness and relational tension. EHA subscales were used as binary variables: a score equal to or above the median value was considered as a higher perception, while a score below the median was considered as a lower perception of the EHA in question. Country differences in meeting the European 5-a-day recommendations were described. Further, the association between EHA and F&V consumption frequency was investigated using multiple linear regression.
Setting:
Regional examination centres in eight European countries.
Participants:
Adolescents (n 3196) aged 12–18 years.
Results:
The mean F&V consumption frequency was 3·27 (sd 2·84) times/d. Only 16·1 % of boys and 18 % of girls in our study sample met the recommendation of five F&V daily. After controlling for age, sex, education level of the parents and country of origin, perceived home warmth was associated with a 16 (95 % CI 9, 22) % higher F&V consumption frequency (P < 0·001).
Conclusions:
F&V consumption frequency was suboptimal in the survey areas. Interventions targeting perceived warmth as a component of EHA could potentially have a positive effect on adolescents’ dietary behaviour.
To determine the association between excess body fat, assessed by skinfold thickness, and the incidence of type 2 diabetes mellitus (T2DM) and hypertension (HT).
Design:
Data from the ongoing PERU MIGRANT Study were analysed. The outcomes were T2DM and HT, and the exposure was skinfold thickness measured in bicipital, tricipital, subscapular and suprailiac areas. The Durnin–Womersley formula and SIRI equation were used for body fat percentage estimation. Risk ratios and population attributable fractions (PAF) were calculated using Poisson regression.
Setting:
Rural (Ayacucho) and urban shantytown district (San Juan de Miraflores, Lima) in Peru.
Participants:
Adults (n 988) aged ≥30 years (rural, rural-to-urban migrants, urban) completed the baseline study. A total of 785 and 690 were included in T2DM and HT incidence analysis, respectively.
Results:
At baseline, age mean was 48·0 (sd 12·0) years and 47 % were males. For T2DM, in 7·6 (sd 1·3) years, sixty-one new cases were identified, overall incidence of 1·0 (95 % CI 0·8, 1·3) per 100 person-years. Bicipital and subscapular skinfolds were associated with 2·8-fold and 6·4-fold risk of developing T2DM. On the other hand, in 6·5 (sd 2·5) years, overall incidence of HT was 2·6 (95 % CI 2·2, 3·1) per 100 person-years. Subscapular and overall fat obesity were associated with 2·4- and 2·9-fold risk for developing HT. The PAF for subscapular skinfold was 73·6 and 39·2 % for T2DM and HT, respectively.
Conclusions:
We found a strong association between subscapular skinfold thickness and developing T2DM and HT. Skinfold assessment can be a laboratory-free strategy to identify high-risk HT and T2DM cases.
To obtain projections of the prevalence of childhood malnutrition indicators up to 2030 and to analyse the changes of wealth-based inequality in malnutrition indicators and the degree of contribution of socio-economic determinants to the inequities in malnutrition indicators in Bangladesh. Additionally, to identify the risk factors of childhood malnutrition.
Design:
Cross-sectional study. A Bayesian linear regression model was used to estimate trends and projections of malnutrition. For equity analysis, slope index, relative index and decomposition in concentration index were used. Multilevel logistic models were used to identify risk factors of malnutrition.
Setting:
Household surveys in Bangladesh from 1996 to 2014.
Participants:
Children under the age of 5 years.
Results:
A decreasing trend was observed for all malnutrition indices. In 1990, predicted prevalence of stunting, wasting and underweight was 55·0, 15·9 and 61·8 %, respectively. By 2030, prevalence is projected to reduce to 28·8 % for stunting, 12·3 % for wasting and 17·4 % for underweight. Prevalence of stunting, wasting and underweight were 34·3, 6·9 and 32·8 percentage points lower in the richest households than the poorest households. Contribution of the wealth index to child malnutrition increased over time and the largest contribution of pro-poor inequity was explained by wealth index. Being an underweight mother, parents with a lower level of education and poorer households were the key risk factors for stunting and underweight.
Conclusions:
Our findings show an evidence-based need for targeted interventions to improve education and household income-generating activities among poor households to reduce inequalities and reduce the burden of child malnutrition in Bangladesh.
We aimed to estimate the cost-effectiveness of brief weight-loss counselling by dietitian-trained practice nurses, in a high-income-country case study.
Design:
A literature search of the impact of dietary counselling on BMI was performed to source the ‘best’ effect size for use in modelling. This was combined with multiple other input parameters (e.g. epidemiological and cost parameters for obesity-related diseases, likely uptake of counselling) in an established multistate life-table model with fourteen parallel BMI-related disease life tables using a 3 % discount rate.
Setting:
New Zealand (NZ).
Participants:
We calculated quality-adjusted life-years (QALY) gained and health-system costs over the remainder of the lifespan of the NZ population alive in 2011 (n 4·4 million).
Results:
Counselling was estimated to result in an increase of 250 QALY (95 % uncertainty interval −70, 560 QALY) over the population’s lifetime. The incremental cost-effectiveness ratio was 2011 $NZ 138 200 per QALY gained (2018 $US 102 700). Per capita QALY gains were higher for Māori (Indigenous population) than for non-Māori, but were still not cost-effective. If willingness-to-pay was set to the level of gross domestic product per capita per QALY gained (i.e. 2011 $NZ 45 000 or 2018 $US 33 400), the probability that the intervention would be cost-effective was 2 %.
Conclusions:
The study provides modelling-level evidence that brief dietary counselling for weight loss in primary care generates relatively small health gains at the population level and is unlikely to be cost-effective.
The present study compared the age of first solid foods in a cohort of preterm infants with term infants and identified factors influencing timing of solid food introduction.
Design:
Structured interviews on infant feeding practices, growth and medical status at term equivalence and at 3, 6, 9 and 12 months corrected postnatal age. The age of solid food introduction was compared between term and preterm infants, and the influence of maternal, infant and milk feeding factors was assessed.
Setting:
This prospective longitudinal study recruited primary carers of preterm and term infants from a regional metropolitan referral hospital in eastern Australia.
Participants:
One hundred and fifty infants (preterm, n 85; term, n 65).
Results:
When corrected for prematurity, preterm infants received solid foods before the recommended age for the introduction of solid foods for term infants. Median introduction of solid foods for preterm infants was 14 weeks corrected age (range 12–17 weeks). This was significantly less than 19 weeks (range 17–21 weeks) for term infants (P < 0·001). Lower maternal education and male gender were associated with earlier introduction of solid foods among preterm infants.
Conclusions:
Preterm infants are introduced to solid foods earlier than recommended for term infants, taking account of their corrected age. Further research is needed to assess any risk or benefit associated with this pattern and thus to develop clear evidence-based feeding guidelines for preterm infants.
In light of the increasing prevalence of juvenile obesity seen around the world, obesogenic environments in general and the food environment in particular are receiving increasing attention in current public health research. Restaurants play a significant role in the food environment. The present study aimed to quantitatively describe and qualitatively evaluate the range of children’s meals available in full-service restaurants in Germany.
Design:
Five hundred restaurants were identified using a systematic quota sampling technique. The individual meals were evaluated using quality standards stipulated by the German Nutrition Society (DGE).
Setting:
Nationwide sample of menus from full-service restaurants.
Participants:
Meals (n 1877) from 500 menus were analysed.
Results:
Menus included 3·76 (sd 1·31) meals for children. About 70 % of the meals were limited to six typical dishes of low nutritional quality. In total, 54 % of meals included French fries or another form of fried potatoes. Of all meals, 23 % did not fulfil any of the eleven quality criteria set by the DGE and 38 % satisfied only one criterion. The majority of dishes on offer featured high energy density while simultaneously having low nutrient density. Healthy dishes were not highlighted visually in any menu.
Conclusions:
The range of dishes on offer for children in German restaurants is severely lacking in variety and in need of improvement from a nutritional point of view. Considering the growing importance of restaurants as food environments, there is a need to improve the presentation of menus and the meals offered.
The present study aimed to examine the combined effects of disease management and food insecurity on physical and mental health in a representative Korean population.
Design:
A cross-sectional study.
Setting:
Data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2012–2015.
Participants:
Adults aged ≥30 years (n 17 934) who participated in the KNHANES.
Results:
Among health-care factors, unmet health-care needs and mental health counselling were different by food insecurity status, with a higher prevalence in adults with food insecurity. The prevalence of underweight was higher in men with food insecurity (5·9 %), whereas the prevalence of obesity was higher in women with food insecurity (37·4 %), than that in men and women with food security. Food insecurity was associated with a high risk of all mental health outcomes. For the combined effects of disease management and food insecurity, unmet health-care needs was related to increased risk of obesity for food-insecure men (Pinteraction = 0·029) and lack of participation in nutrition education or counselling was related to increased risk of obesity for food-insecure women (Pinteraction = 0·010). In addition, higher unmet health-care needs in adults with food insecurity was related to higher risk of mental health outcomes.
Conclusions:
Unmet health-care needs may exacerbate obesity for food-insecure men and mental health problems for both food-insecure men and women. In addition, lack of participation in nutrition education or counselling may exacerbate the obesity for food-insecure women.
The present study aimed to identify whether discretionary food consumption declined in an intervention focused primarily on promoting fruit and vegetable consumption. We also aimed to identify potential mediators explaining intervention effects on discretionary food consumption.
Design:
Secondary analysis of data from the ShopSmart study, a randomised controlled trial involving a 6-month intervention promoting fruit and vegetable consumption. Linear regression models examined intervention effects on discretionary food consumption at intervention completion (T2). A half-longitudinal mediator analyses was performed to examine the potential mediating effect of personal and environmental factors on the association between the intervention effects and discretionary food consumption. Indirect (mediated) effects were tested by the product of coefficients method with bootstrapped se using Andrew Hayes’ PROCESS macro for SPSS.
Setting:
Women were recruited via the Coles FlyBuys loyalty card database in socio-economically disadvantaged suburbs of Melbourne, Australia.
Participants:
Analyses included 225 women (116 intervention and 109 control).
Results:
Compared with controls, intervention participants consumed fewer discretionary foods at T2, after adjusting for key confounders (B = −0·194, 95 % CI −0·378, −0·010 servings/d; P = 0·039). While some mediators were associated with the outcome (taste, outcome expectancies, self-efficacy, time constraints), there was no evidence that they mediated intervention effects.
Conclusions:
The study demonstrated that a behavioural intervention promoting fruit and vegetable consumption among socio-economically disadvantaged participants was effective in reducing discretionary food intake. Although specific mediators were not identified, researchers should continue searching for mechanisms by which interventions have an effect to guide future programme design.
We investigated short- and long-term indicators of malnutrition and diet before and after the community-based ‘Breaking the Cycle of Poverty’ multidisciplinary intervention.
Design:
A historically and geographically controlled study using data collected in 2013 and 2016. We compared the prevalence of short-term indicators (anaemia, breast-feeding duration and minimum dietary diversity) and long-term indicators (stunting and wasting) in exposed communities at two time points. We then compared these factors in geographic areas exposed or not exposed to intervention. We conducted logistic regression analyses on the 2016 sample to measure associations between living in intervention communities and child growth indicators.
Setting:
Berd region, a chronic conflict zone near the north-eastern border of Armenia and Azerbaijan.
Participants:
Children aged 6 months to 6 years.
Results:
Analyses included data from 2013 comprising 382 children, and data from 2016 comprising 348 children living in communities where the programme was implemented, and 635 children from unexposed communities. Anaemia prevalence in exposed communities was significantly lower in 2016 v. 2013 (10·9 v. 19·1 %, P < 0·01). Minimum dietary diversity (79·0 v. 68·1 %, P < 0·001) and breast-feeding duration (13·0 v. 11·5 months, P < 0·002) were significantly improved in exposed communities. Prevalences of stunting (11·5 v. 10·2 %, P = 0·57) and wasting (4·8 v. 2·0 %, P = 0·07) were not significantly different. Odds of anaemia were significantly lower (OR = 0·24, 95 % CI 0·16, 0·36) in intervention communities.
Conclusions:
Exposure to a community-based multidisciplinary intervention reduced the rate of anaemia and improved dietary indicators.
To compare the impact on child diet and growth of a multisectoral community intervention v. nutrition education and livestock management training alone.
Design:
Longitudinal community-based randomized trial involving three groups of villages assigned to receive: (i) Full Package community development activities, delivered via women’s groups; (ii) livestock training and nutrition education alone (Partial Package); or (iii) no intervention (Control). Household surveys, child growth monitoring, child and household diet quality measures (diet diversity (DD), animal-source food (ASF) consumption) were collected at five visits over 36 months. Mixed-effect linear regression and Poisson models used survey round, treatment group and group-by-round interaction to predict outcomes of interest, adjusted for household- and child-specific characteristics.
Setting:
Banke, Nepal.
Participants:
Households (n 974) with children aged 1–60 months (n 1333).
Results:
Children in Full Package households had better endline anthropometry (weight-for-age, weight-for-height, mid-upper-arm-circumference Z-scores), DD, and more consumption of ASF, after adjusting for household- and child-specific characteristics. By endline, compared with Partial Package or Control groups, Full Package households demonstrated preferential child feeding practices and had significantly more improvement in household wealth and hygiene habits.
Conclusions:
In this longitudinal study, a comprehensive multisectoral intervention was more successful in improving key growth indicators as well as diet quality in young children. Provision of training in livestock management and nutrition education alone had limited effect on these outcomes. Although more time-consuming and costly to administer, incorporating nutrition training with community social capital development was associated with better child growth and nutrition outcomes than isolated training programmes alone.
Our study analysed evolving regional commitments on food policy in the Pacific. Our aim was to understand regional priorities and the context of policy development, to identify opportunities for progress.
Design:
We analysed documentation from a decade of regional meetings in order to map regional policy commitments relevant to healthy diets. We focused on agriculture, education, finance, health, and trade sectors, and Heads of State forums. Drawing on relevant political science methodologies, we looked at how these sectors ‘frame’ the drivers of and solutions to non-communicable diseases (NCD), their policy priorities, and identified areas of coherence and tension.
Setting:
The Pacific has among the highest rates of non-communicable diseases in the world, but also boasts an innovative and proactive response. Heads of State have declared NCD a ‘crisis’ and countries have committed to specific prevention activities set out in a regional ‘Roadmap’. Yet, diet-related NCD risk-factors remain stubbornly high and many countries face challenges in establishing a healthy food environment.
Results:
Policies to improve food environments and prevent NCD are a stated priority across regional policy forums, with clear agreement on the need for a multi-sectoral response. However, we identified challenges in sustaining these priorities as political attention fluctuated. We found examples of inconsistencies and tension in sectoral responses to the NCD epidemic that may restrict implementation of the multi-sectoral action.
Conclusion:
Understanding the priorities and positions underpinning sectoral responses can help drive a more coherent NCD response, and lessons from the Pacific are relevant to public health nutrition policy and practice globally.
To describe the development of Fiji’s fruit and vegetable fiscal policies between 2010 and 2014 and explore the impact they have had on import volumes.
Design:
Qualitative case study and in-depth analysis of policy process. Policy impact was assessed using publicly available import volume data and prices of food products.
Setting:
Fiji.
Participants:
Senior government policy makers, non-communicable disease officers from the Ministry of Health and Medical Services (MoHMS) and supermarket managers.
Results:
In 2011, the Fijian Government introduced an import excise of 10 % on vegetables and reduced the import fiscal duty on fruit that was also grown in Fiji by 10 %. The import tax on vegetables was removed in 2012 in response to a MoHMS request. Policy makers from several sectors supported the MoHMS request, recognized their leadership and acknowledged the importance of collaboration in achieving the removal of the excise. Tariff reductions appear to have contributed to increases in the volume of vegetables (varieties not grown in Fiji) and fruit (varieties grown in Fiji) imported, but it is not clear if this increased population consumption.
Conclusions:
Reductions in import duties appear to have contributed to increases in volumes of vegetables and fruit imported into Fiji. This case study has demonstrated that governments can use fiscal policy to meet the needs of a range of sectors including health, agriculture and tourism.
