To determine whether school-level participation in the federal Community Eligibility Provision (CEP), which provides free school lunch to all students, is associated with school meal participation rates. Participation in school meals is important for decreasing food insecurity and improving child health and well-being.

Quasi-experimental evaluation using negative binomial regression to predict meal count rates per student-year overall and by reimbursement level adjusted for proportion eligible for free and reduced-price lunch (FR eligibility) and operating days.

Schools (grades kindergarten to 12th) participating in the National School Lunch Program (NSLP) in Maryland and Pennsylvania, USA, from the 2013–2015 (n 1762) and 2016–2017 (n 2379) school years.

Administrative, school-level data on school lunch counts and student enrolment.

CEP was associated with a non-significant 6 % higher total NSLP meal count adjusting for FR eligibility, enrolment and operating days (rate ratio = 1·06, 95 % CI 0·98, 1·14). After controlling for participation rates in the year prior to CEP implementation, the programme was associated with a significant 8 % increase in meal counts (rate ratio = 1·08, 95 % CI 1·03, 1·12). In both analyses, CEP was associated with lower FR meal participation and substantial increases in paid meal participation.

School-level implementation of CEP is associated with increases in total school meal participation. Current funding structures may prevent broader adoption of the programme by schools with fewer students eligible for FR meals.

The present study aimed to evaluate the effect of mandatory iodine fortification of bread on the iodine status of South Australian populations using newborn thyroid-stimulating hormone (TSH) concentration as a marker.

The study used an interrupted time-series design.

TSH data collected between 2005 and 2016 (n 211 033) were extracted from the routine newborn screening programme in South Australia for analysis. Iodine deficiency is indicated when more than 3 % of newborns have TSH > 5 mIU/l.

Newborns were classified into three groups: the pre-fortification group (those born before October 2009); the transition group (born between October 2009 and June 2010); and the post-fortification group (born after June 2010).

The percentage of newborns with TSH > 5 mIU/l was 5·1, 6·2 and 4·6 % in the pre-fortification, transition and post-fortification groups, respectively. Based on a segmented regression model, newborns in the post-fortification period had a 10 % lower risk of having TSH > 5 mIU/l than newborns in the pre-fortification group (incidence rate ratio (IRR) = 0·90; 95 % CI 0·87, 0·94), while newborns in the transitional period had a 22 % higher risk of having TSH > 5 mIU/l compared with newborns in the pre-fortification period (IRR = 1·22; 95 % CI 1·13, 1·31).

Using TSH as a marker, South Australia would be classified as mild iodine deficiency post-fortification in contrast to iodine sufficiency using median urinary iodine concentration as a population marker. Re-evaluation of the current TSH criteria to define iodine status in populations is warranted in this context.

The present study aimed to conduct a process evaluation of a multicomponent nutritional telemonitoring intervention implemented among Dutch community-dwelling older adults.

A mixed-methods approach was employed, guided by the process evaluation framework of the Medical Research Council and the Unified Theory of Acceptance and Use of Technology. The process indicators reach, dose, fidelity and acceptability were measured at several time points within the 6-month intervention among participants and/or nurses.

The intervention was implemented in the context of two care organisations in the Netherlands.

In total, ninety-seven participants (average age 78 years) participated in the intervention and eight nurses were involved in implementation.

About 80 % of participants completed the intervention. Dropouts were significantly older, had worse cognitive and physical functioning, and were more care-dependent. The intervention was largely implemented as intended and received well by participants (satisfaction score 4·1, scale 1–5), but less well by nurses (satisfaction score 3·5, scale 1–5). Participants adhered better to weight telemonitoring than to telemonitoring by means of questionnaires, for which half the participants needed help. Intention to use the intervention was predicted by performance expectancy (β=0·40; 95 % CI 0·13, 0·67) and social influence (β=0·17; 95 % CI 0·00, 0·34). No association between process indicators and intervention outcomes was found.

This process evaluation showed that nutritional telemonitoring among older adults is feasible and accepted by older adults, but nurses’ satisfaction should be improved. The study provided relevant insights for future development and implementation of eHealth interventions among older adults.

The objective of this study was to examine climate impact from diet across background and sociodemographic characteristics in a population-based cohort in northern Sweden.

A cross-sectional study within the Västerbotten Intervention Programme. Dietary data from a 64-item food frequency questionnaire collected during 1996–2016 were used. Energy-adjusted greenhouse gas emissions (GHGE) for all participants, expressed as kg carbon dioxide equivalents/day and 4184 kJ (1000 kcal), were estimated using data from life cycle analyses. Differences in background and sociodemographic characteristics were examined between participants with low and high GHGE from diet, respectively. The variables evaluated were age, BMI, physical activity, marital status, level of education, smoking, and residence.

Västerbotten county in northern Sweden.

In total, 46 893 women and 45 766 men aged 29–65 years.

Differences in GHGE from diet were found across the majority of examined variables. The strongest associations were found between GHGE from diet and age, BMI, education, and residence (all P < 0·001), with the highest GHGE from diet found among women and men who were younger, had a higher BMI, higher educational level, and lived in urban areas.

This study is one of the first to examine climate impact from diet across background and sociodemographic characteristics. The results show that climate impact from diet is associated with age, BMI, residence and educational level amongst men and women in Västerbotten, Sweden. These results define potential target populations where public health interventions addressing a move towards more climate-friendly food choices and reduced climate impact from diet could be most effective.

In Ireland, the major causes of death are CVD. The current Irish healthy eating guidelines and food pyramid primarily advocate a low-fat diet. However, there is overwhelming scientific evidence for the benefits of a Mediterranean diet (Med Diet) in the prevention and management of metabolic disease as well as improving overall health and well-being. In the current commentary, the rationale to incorporate the principles of the Med Diet into the Irish dietary guidelines is presented.

Perspectives of authors.

Local and international.

Populations in Europe, North America and Australia.

Adopting components of the Med Diet presents a more evidence-based approach to updating the current Irish dietary guidelines. Experience and lessons from other non-Mediterranean countries show that it could be a feasible and effective solution to improving the dietary habits of the Irish population to prevent and mange chronic diseases.

Policies and programmes to address perceived barriers to the Med Diet’s implementation and uptake in non-Mediterranean countries should be promoted.

To summarise findings of systematic reviews that distinctively report dietary intervention components and their effects on diet-, health- and economic-related outcomes in the workplace setting.

MEDLINE, Embase, CINAHL, Web of Science, Cochrane Library and Google Scholar were searched in December 2014 and the search was updated in August 2017.

The search identified 1137 titles, of which nineteen systematic reviews from the initial search and two systematic reviews from the updated search met the inclusion criteria (twenty-one systematic reviews, published in twenty-two papers). Most systematic reviews were of moderate quality and focused on dietary behaviour change outcomes and some health-related biomarkers. Evidence was strongest for interventions to increase fruit and vegetable intake, reduce fat intake, aid weight loss and reduce cholesterol. Few reported workplace-related and evaluation outcomes.

These findings suggest that workplace dietary interventions can positively influence diet and health outcomes. Suggestions for effective interventions components have been made.

The association between gestational weight gain (GWG) and exclusive breast-feeding (EBF) practices remains unclear. The present study evaluated the association between GWG and EBF in the first 6 months postpartum among primiparas in rural China.

The study population was drawn from a previous randomized controlled trial, and the relevant data were obtained from an electronic, population-based perinatal system and a monitoring system for child health care. GWG was categorized according to the guidelines of the Institute of Medicine.

Five rural counties in Hebei Province, China.

A total of 8449 primiparas.

Of the women, 58·7 % breast-fed exclusively for the first 6 months postpartum. Overweight women who gained either more or less weight than the recommended GWG tended to experience failure of EBF (OR=0·49; 95 % CI 0·34, 0·70; P<0·001 and OR=0·79; 95 % CI 0·63, 0·99; P=0·048, respectively). The same results were also observed among obese women; the OR for lower and greater weight gain were 0·28 (95 % CI 0·08, 0·94; P=0·04) and 0·55 (95 % CI 0·32, 0·95; P=0·03), respectively.

GWG that is below or above the Institute of Medicine recommendations is associated with EBF behaviour for the first 6 months postpartum in overweight and obese primiparas in rural China.

Dietary guidelines are an essential policy tool for facilitating optimal dietary patterns and healthy eating behaviours. We report: (i) the methodological approach adopted for developing the National Dietary Guidelines of Greece (NDGGr) for Infants, Children and Adolescents; and (ii) the guidelines for children aged 1–18 years.

An evidence-based approach was employed to develop food-based recommendations according to the methodologies of the WHO, FAO and European Food Safety Authority. Physical activity recommendations were also compiled. Food education, healthy eating tips and suggestions were also provided.

The NDGGr encompass food-based nutritional and physical activity recommendations for promoting healthy dietary patterns and eating behaviours and secondarily to serve as a helpful tool for the prevention of childhood overweight and obesity.

The NDGGr include food-based recommendations, food education and health promotion messages regarding: (i) fruits; (ii) vegetables; (iii) milk and dairy products; (iv) cereals; (v) red and white meat; (vi) fish and seafood; (vii) eggs; (viii) legumes; (ix) added lipids, olives, and nuts; (x) added sugars and salt; (xi) water and beverages, and (xii) physical activity. A Nutrition Wheel, consisting of the ten most pivotal key messages, was developed to enhance the adoption of optimal dietary patterns and a healthy lifestyle. The NDGGr additionally provide recommendations regarding the optimal frequency and serving sizes of main meals, based on the traditional Greek diet.

As a policy tool for promoting healthy eating, the NDGGr have been disseminated in public schools across Greece.

Professional sport occupies a prominent cultural position in societies across the globe and commercial organisations make use of this to promote their products. The present scoping review explores existing academic literature on the relationship between professional sports clubs and food and drink marketing and considers how this relationship may impact upon the public’s health.

The scoping review searched six databases. Experts were also consulted. Records written in languages other than English were excluded. We also excluded records relating to mega events (e.g. Olympics, Football World Cup) and alcohol marketing, because of the attention already given to these.

Professional sports clubs.

We identified 18 166 titles, reviewed 163 abstracts and read twenty-six full texts. We included six papers in the review. Four were from Australia and New Zealand. The Australasian literature focused largely on the marketing of foods and beverages to children and the potential impact on consumption. Single papers from researchers in Turkey and the USA were identified. The Turkish paper analysed shirt sponsorship in football leagues internationally and showed food and beverage (including alcohol) companies were the most common sponsors. The US paper examined a mixed reaction to a football team named after an energy drink.

Commercial relationships between professional sports clubs and Big Food corporations have largely eluded scrutiny in much of the world. The current review highlights the lack of public health research on these relationships. Research exploring the interdependent commercial practices of food and drink companies and professional sports clubs is urgently needed.

The present study reviewed the literature on iodine status among women of childbearing age and pregnant women in the UK. Particular attention was given to study quality and methods used to assess iodine status.

A systematic review was conducted to examine the literature and critically evaluate study design.

Studies were identified in PubMed, Web of Science, Scopus and Ovid MEDLINE databases, as well as from secondary references.

Women of childbearing age or pregnant, living in the UK.

Fifty-seven articles were identified and twelve articles were selected, including a total of 5283 women. Nine studies conducted urinary iodine assessments, three studies conducted dietary assessments only, and seven studies classified their target population as iodine deficient according to WHO criteria.

No single study from the selected articles could produce nationally representative results regarding the prevalence of iodine deficiency among the female population in the UK. Consideration of the evidence as a whole suggests that women of childbearing age and pregnant women in the UK are generally iodine insufficient. Further large-scale research is required for more accurate and reliable evidence on iodine status in the UK.

The current study assessed changes in children and mothers’ nutritional status before and after raising Bangladeshi households out of extreme poverty through an income-generating activities (IGA) programme.

Extreme poor households took part in the IGA programme for 2 years and recruitment took place over four waves in annual cycles. Children and mothers were measured with regarding their nutritional status before and after the IGA programme commenced.

Rural Bangladesh.

Three-hundred and eighty-two children under 5 years of age at recruitment, and their mothers.

After 2 years of the IGA programme, the prevalence of stunting significantly declined from 40·3 % to 33·0 % (P = 0·003), anaemia declined from 51·6 % to 44·0 % (P = 0·020) while mothers’ CED (Chronic Energy Deficiency) declined from 52·0 % to 42·7 % (P < 0·001), but no significant changes were found in children’s wasting, declining from 25·4 % to 21·5 %, underweight which remained the same at 43·2 %, while mothers’ anaemia rose from 39·3 % to 42·7 %. There were also highly significant improvements in household socio-economic status. Increases in socio-economic security (especially in relation to cash savings and net income) and improvements in food quantity and quality (indicated by greater food diversity and animal food intake) were associated with normal nutritional status, and cessation of open defecation was associated with reduction in mothers’ and child anaemia.

The IGA programme was associated with increased household socio-economic security, such as asset accumulation, food security and sanitation, and with improvements in the nutritional status of children and their mothers in extreme poor households.

The present review evaluated the effectiveness of environmental-based interventions aimed at improving the dietary and physical activity behaviours and body composition indices of adults in institutions.

A systematic review was conducted. Electronic databases (MEDLINE, Embase, PsycINFO, CINAHL, The Cochrane Library, Web of Science, ProQuest Dissertation and Theses, Scopus and Athena) were searched for relevant articles published between database inception and October 2017. Searching, selecting and reporting were undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

Military establishments and maritime workplaces.

Adults in institutions, aged 18–45 years.

A total of 27842 articles were screened for eligibility, nine studies (reported in eleven articles) were included in the review. Five studies used multilevel strategies and four used environmental strategies only. Duration of follow-up ranged from 3 weeks to 10 years. Eight of the studies reported significant positive effects on dietary behaviours, but effect sizes varied. The study that targeted physical activity had no effect on activity levels but did have a significant positive effect on physical fitness. No evidence was identified that the studies resulted in improvements in body composition indices.

The evidence base appears to be in favour of implementing environmental interventions in institutions to improve the dietary behaviours of adults. However, due to the small number of studies included in the review, and the variable methodological quality of the studies and intervention reporting, further well-designed evaluation studies are required.

Unequal obesity distributions among adult populations have been reported in low- and middle-income countries, but mainly based on data of women of reproductive age. Moreover, incorporation of ever-changing skewed BMI distributions in analyses has been a challenge. Our study aimed to assess magnitude and rates of change in BMI distributions by age and sex.

Shapes of BMI distributions were estimated for 2005 and 2010, and their changes were assessed, using the generalized additive model for location, scale and shape (GAMLSS) and assuming BMI follows a Box–Cox power exponential (BCPE) distribution.

Nationally representative, repeated cross-sectional health surveys conducted between 2005 and 2013 in Mexico, Colombia and Peru.

Adult men and non-pregnant women aged 20–69 years.

Whereas women had more right-shifted and wider BMI distributions than men in almost all age groups across the countries in 2010, men in their 30s–40s experienced more rapid increases in BMI between 2005 and 2010, notably in Peru. The highest increase in overweight and obesity prevalence was observed among Peruvian men of 35–39 years, with a 5-year increase of 21 percentage points.

The BCPE–GAMLSS method is an alternative to analyse measurements with time-varying distributions visually, in addition to conventional indicators such as means and prevalences. Consideration of differences in BMI distributions and their changes by sex and age would provide vital information in tailoring relevant policies and programmes to reach target populations effectively. Increases in BMI portend increases of obesity-associated diseases, for which preventive and preparative actions are urgent.

To establish the factors that determine food fussiness, to explore if child age determines the extent to which these factors influence food fussiness and to identify whether parental neophobia is an independent determinant of food fussiness.

Cross-sectional data from the National Children’s Food Survey (2003–2004). The Children’s Eating Behaviour Questionnaire (CEBQ) assessed eating behaviours in children. The Food Neophobia Scale (FNS) assessed parental food neophobia. Young children were classified as 5–8 years old with older children classified as 9–12 years old.

Republic of Ireland.

Nationally representative sample of Irish children aged 5–12 years (n 594).

Parents identifying child’s food preferences as a barrier to providing their child with a healthy diet was significantly associated with increased food fussiness in younger (P<0·001) and older children (P<0·001). Higher levels of parental neophobia were significantly associated with an increase in food fussiness in younger (P<0·05) and older (P<0·001) children. Food advertising as a barrier to providing a healthy diet was inversely associated with food fussiness in younger children (P<0·05). In older children, there was a significant inverse association between child’s BMI and food fussiness (P<0·05), but not to the extent that a difference in weight status was noted. Family mealtimes in older children were associated with significantly lower levels of food fussiness (P<0·05).

Findings from the present study identify that a child’s age does determine the extent to which certain factors influence food fussiness and that parental neophobia is an independent determinant of food fussiness.

The present study examined the effect of ingredient bundles (i.e. measured ingredients with recipes) and recipe tastings as a strategy to increase the selection of healthy, target foods (kale, brown rice and whole-wheat pasta).

Each of the three conditions was tested once per week for three weeks. The conditions were: Treatment 1 (T1), recipe tastings only; Treatment 2 (T2), ingredient bundle plus recipe tastings; and Control, no intervention.

Food pantry clients.

Controlling for family size and intervention week, the likelihood of clients in T2 (n 160) selecting at least one target item compared with the Control group (n 160) was 3·20 times higher for kale, 4·76 times higher for brown rice and 7·25 times higher for whole-wheat pasta. Compared with T1 (n 128), T2 clients were 2·67 times more likely to select kale, 7·67 times more likely to select brown rice and 11·43 times more likely to select whole-wheat pasta. No differences between T1 and the Control group were found.

Findings suggest that innovative, nudging strategies such as ingredient bundles may increase appeal of foods and encourage pantry clients to select healthier options.
