To assess the Na content reported on the labels of processed foods sold in Brazil that are usually consumed as snacks by children and adolescents.

Cross-sectional study that assessed Na content and serving size reporting on processed food labels.

A supermarket that is part of a large chain in Brazil.

All foods available for sale at the study’s location and reported in the literature as snacks present in the diets of Brazilian children and adolescents.

Of the 2945 processed foods, 87 % complied with the reference serving sizes, although variability in reporting was observed in most of the food subgroups. In addition, 21 % of the processed foods had high Na levels (>600 mg/100 g) and 35 % had medium Na levels (>120 and ≤600 mg/100 g). The meats, oils, fats and seeds groups as well as the prepared dishes had higher percentages of foods classified as high Na (81 %, 58 % and 53 %, respectively).

Most of the processed foods had high or medium Na content. We emphasize the importance of revising Brazilian nutrition labelling legislation to standardize reference serving sizes to avoid variation. Besides, we point out the potential for reducing Na levels in most processed foods, as evidenced by the variability in Na content within subgroups. Finally, we have identified the need to develop a method to classify Na levels in processed foods with specific parameters for children and adolescents.

Nitrate and nitrite are probable human carcinogens when ingested under conditions that increase the formation of N-nitroso compounds. There have been limited efforts to develop US databases of dietary nitrate and nitrite for standard FFQ. Here we describe the development of a dietary nitrate and nitrite database and its calibration.

We analysed data from a calibration study of 1942 members of the NIH–AARP (NIH–AARP, National Institutes of Health–AARP) Diet and Health Study who reported all foods and beverages consumed on the preceding day in two non-consecutive 24 h dietary recalls (24HR) and completed an FFQ. Based on a literature review, we developed a database of nitrate and nitrite contents for foods reported on these 24HR and for food category line items on the FFQ. We calculated daily nitrate and nitrite intakes for both instruments, and used a measurement error model to compute correlation coefficients and attenuation factors for the FFQ-based intake estimates using 24HR-based values as reference data.

FFQ-based median nitrate intake was 68·9 and 74·1 mg/d, and nitrite intake was 1·3 and 1·0 mg/d, in men and women, respectively. These values were similar to 24HR-based intake estimates. Energy-adjusted correlation coefficients between FFQ- and 24HR-based values for men and women respectively were 0·59 and 0·57 for nitrate and 0·59 and 0·58 for nitrite; energy-adjusted attenuation factors were 0·59 and 0·57 for nitrate and 0·47 and 0·38 for nitrite.

The performance of the FFQ in assessing dietary nitrate and nitrite intakes is comparable to that for many other macro- and micronutrients.

To develop a BPA Exposure Assessment Module (BEAM) for use in large observational studies and to evaluate the ability of the BEAM to estimate bisphenol A (BPA) exposure levels.

The BEAM was designed by modifying an FFQ with questions targeting known sources of BPA exposure. Frequency of intake of known dietary sources of BPA was assessed using the BEAM and three 24 h food records as a reference diet measurement tool. Urinary BPA (uBPA) levels were measured as the criterion tool in a pooled urine sample (nine spot samples per participant). Spearman correlations, linear regression and weighted kappa analysis were used to evaluate the ability of the BEAM and food records to estimate BPA exposure levels.

Minneapolis/Saint Paul, MN, USA.

Sixty-eight healthy adult (20–59 years) volunteers.

Dietary BPA intake assessed by the BEAM was not associated with uBPA levels and was unable to predict participants’ rank by uBPA levels. BEAM models with all a priori predictors explained 25 % of the variability in uBPA levels. Canned food intake assessed by food records was associated with uBPA levels, but was unable to rank participants by uBPA levels. Multivariable-adjusted food record models with a priori predictors explained 41 % of the variability in uBPA levels.

Known dietary sources of BPA exposure explained less than half the variability in uBPA levels, regardless of diet assessment method. Findings suggest that a questionnaire approach may be insufficient for ranking BPA exposure level and additional important sources of BPA exposure likely exist.

Food insecurity is a salient health issue comprised of four dimensions – food access, availability, utilization and stability over time. The aim of the present study was to conduct a systematic literature review to identify all multi-item tools that measure food insecurity and explore which of the dimensions they assess.

Five databases were searched (CENTRAL, CINAHL plus, EMBASE, MEDLINE, TRIP) for studies published in English since 1999. Inclusion criteria included human studies using multi-item tools to measure food security and studies conducted in developed countries. Manuscripts describing the US Department of Agriculture Food Security Survey Module, that measures ‘food access’, were excluded due to wide acceptance of the validity and reliability of this instrument. Two authors extracted data and assessed the quality of the included studies. Data were summarized against the dimensions of food insecurity.

A systematic review of the literature.

The majority of tools were developed in the USA and had been used in different age groups and cultures.

Eight multi-item tools were identified. All of the tools assessed the ‘food access’ dimension and two partially assessed the dimensions ‘food utilization’ and ‘stability over time’, respectively. ‘Food availability’ was not assessed by existing tools.

Current tools available for measuring food insecurity are subjective, limited in scope, with a majority assessing only one dimension of food insecurity (access). To more accurately assess the true burden of food insecurity, tools should be adapted or developed to assess all four dimensions of food insecurity.

To describe the methods, strengths and limitations of available data sources for estimating US meat and protein consumption in order to facilitate accurate interpretations and applications.

We examined agricultural supply and dietary intake databases from the US Department of Agriculture (USDA), the US Department of Health and Human Services and the FAO to describe their methodology and to report the most recent estimates for meat and protein consumption.

Together, loss-adjusted agricultural supply data and dietary recall data provide the best available estimates of US consumption; the most recent sources indicated that US citizens (ages 2 years and over) consume 4·4–5·9 oz (125·9–166·5 g) of total meat and 6·2–7·4 oz-eq (175·2–209·4 g-eq) from the USDA Protein Foods Group per day. Meat constitutes the majority of intake within the Protein Foods Group, and red meat and processed meat constitute the majority of total meat intake. Nutrient supply data indicate that total meat represents an estimated 43·1 % of the total protein available in the US food supply, but without any loss-adjusted nutrient data, per capita protein intake is best estimated by dietary recall data to be 79·9 g/d.

In order to address public health concerns related to excess meat and/or protein consumption, practitioners, educators and researchers must appropriately use available data sources in order to accurately report consumption at the population level. Implications for comparing these estimates with various recommended intakes are discussed.

To examine the consumption of plain water among children in France and compare total water intakes with guidelines issued by the European Food Safety Authority (EFSA).

Nationally representative data were used to assess food, beverage and water consumption by sex, age group (4–8 years, 9–13 years), income-to-poverty ratio, eating occasion and location. Beverages were classified into nine groups: water (tap or bottled), milk, 100 % fruit juice, sodas, fruit drinks, hot beverages, sports drinks and flavoured waters. Total water volume in relation to energy intake (litres/kcal) was also examined.

INCA 2 study (Étude Individuelle Nationale des Consommations Alimentaires 2006–2007).

French children (n 835) aged 4–13 years.

Total water intakes were accounted for by plain water (34 %), beverages (26 %) and food moisture (40 %). Plain water could be tap (18 %) or bottled (16 %). Older children drank more plain water than did younger children and boys drank more plain water than did girls. No socio-economic gradient for plain water consumption was observed. About 90 % of children did not meet the EFSA water intake recommendations. The daily water shortfall ranged from 367 to 594 ml/d. Water-to-energy ratio was 0·75–0·77 litres/1000 kcal (4184 kJ). Children drank milk at breakfast and plain water during lunch and dinner. Caloric beverages provided 10 % of dietary energy; consumption patterns varied by eating location.

Total water intakes among young children in France were below EFSA-recommended levels. Analyses of beverage consumption patterns by eating occasion and location can help identify ways to increase water consumption among children.

To describe key characteristics of the dietary habits of Samoans residing in Logan, Queensland and to compare these characteristics with comparable populations.

Dietary intake was measured using a self-administered structured questionnaire between December 2012 and March 2013. Demographic characteristics included age and sex. Questionnaire results were compared with data from samples of Brisbane residents of similar social and economic characteristics and Pacific Islanders in New Zealand. The association between demographic characteristics and diet was investigated.

Logan, Queensland, Australia.

Samoans aged 16 years and older.

A total of 207 Samoans participated, ninety-six (46 %) of whom were male. Of the participants, seventy-nine (38 %) were aged 16–29 years, sixty-three (30 %) were aged 30–49 years and sixty-five (31 %) were aged ≥50 years. Younger adults were significantly more likely to eat hamburgers, pizza, cakes, savoury pastries, potato crisps, sweets and soft drinks (all variables P<0·001). Among Samoans, 44·7 % consumed two or more pieces of fruit daily, compared with 43·8 % of comparable Brisbane residents (relative risk=1·0; 95 % CI 0·8, 1·2). Three or more servings of vegetables each day were consumed by 9·2 % of Samoans compared with 36·6 % of comparable Brisbane residents (relative risk=3·8; 95 % CI 2·5, 6·0).

Samoans are consuming significantly fewer vegetables and more discretionary foods than other populations. Socio-economic factors, length of stay in Australia and cultural practices may impact upon Samoans’ diets. Further comprehensive studies on Samoans’ dietary habits in Australia are recommended.

Dairy products are sources of protein and micronutrients important in a healthy diet. The purpose of the present analysis was to estimate consumption of dairy products by Brazilians and identify contributions of dairy products to nutrient intakes.

Dairy consumption data were obtained from 24 h dietary records. Dairy products were defined as milk (including flavoured), cheese and yoghurt. Estimates of dairy product intakes were generated for all individuals, individuals in urban and rural households and for age groups 10–18 years, 19–59 years and ≥60 years. Contributions to nutrient intakes were estimated for the total sample and sub-populations.

Nationwide cross-sectional survey, 2008–2009.

Nationally representative sample of individuals aged ≥10 years in the Individual Food Intake survey, a component of the Brazilian Household Budget Survey (n 34 003).

Among individuals aged ≥10 years, per capita intake of dairy products was 142 (se 2·1) g/d. Dairy product intake was higher among individuals in urban compared with rural areas and among groups 10–18 years and ≥60 years compared with adults aged 19–59 years. Dairy products accounted for 6·1 % of daily energy intake, 7·3 % of protein, 16·9 % of saturated fat, 11·1 % and 4·3 % of total and added sugars, respectively, and 10·2–37·9 % of daily Ca, vitamin D, P, vitamin A and K.

Dairy products were substantial contributors to daily intakes of selected nutrients of concern in Brazil, although mean daily dairy product consumption was less than a typical portion. Education efforts in Brazil to raise awareness about the nutritional role of dairy foods may serve to improve overall diet quality.

The persistence of undernutrition, along with overweight and obesity, constitute the double burden of malnutrition. The present study aimed to: (i) describe the prevalence and trends of concurrent stunting and overweight in Indonesian children; (ii) identify potentially associated risk factors; and (iii) determine whether stunted children are at greater risk of overweight compared with those of healthy height.

A secondary data analysis of children aged 2·0–4·9 years in four cross-sectional studies of the Indonesian Family Life Survey. Children’s height and BMI Z-scores were calculated based on the WHO Child Growth Standards (2006). We defined ‘concurrent stunting and overweight’ as height-for-age Z-score <−2 and BMI Z-score >+1. Multivariate generalised linear latent and mixed models were used to determine associated risk factors.

Thirteen out of twenty-seven provinces in Indonesia.

Children (n 4101) from four waves of the Indonesian Family Life Survey (1993–2007).

There were inconsistent trends in the prevalence of concurrent stunting and overweight from waves 1 to 4. Children were more likely to be stunted and overweight when they were in the youngest age group (2·0–2·9 years), were weaned after the age of 6 months, had short-statured mothers or lived in rural areas. Stunted children were significantly more likely to be overweight than healthy-height children (OR>1) but did not differ significantly different across each wave (OR=1·34–2·01).

Concurrent stunting and overweight occurs in Indonesian children aged 2·0–4·9 years. Current policies and programmes need to be tailored for the management of this phenomenon.

A tax on sugar-sweetened beverages (SSB) has been proposed to address population weight gain but the effect across socio-economic position (SEP) is unclear. The current study aimed to clarify the differential impact(s) of SSB taxes on beverage purchases and consumption, weight outcomes and the amount paid in SSB taxes according to SEP.

Databases (OVID and EMBASE) and grey literature were systematically searched in June 2015 to identify studies that examined effects of an SSB price increase on beverage purchases or consumption, weight outcomes or the amount paid in tax across SEP, within high-income countries.

Of the eleven included articles, three study types were identified: (i) those that examined the association between variation in SSB taxes and SSB consumption and/or body weight (n 3); (ii) price elasticity estimation of SSB demand (n 1); and (iii) modelling of hypothetical SSB taxes by combining price elasticity estimates with population SEP-specific beverage consumption, energy intake or body weight (n 7). Few studies statistically tested differences in outcomes between SEP groups. Nevertheless, of the seven studies that reported on changes in weight outcomes for the total population following an increase in SSB price, all reported either similar reductions in weight across SEP groups or greater reductions for lower compared with higher SEP groups. All studies that examined the average household amount paid in tax (n 5) reported that an SSB tax would be regressive, but with small differences between higher- and lower-income households (0·10–1·0 % and 0·03 %–0·60 % of annual household income paid in SSB tax for low- and high-income households, respectively).

Based on the available evidence, a tax on SSB will deliver similar population weight benefits across socio-economic strata or greater benefits for lower SEP groups. An SSB tax is shown to be consistently financially regressive, but to a small degree.

To analyse the gluteal adipose-tissue fatty-acid profiles from Cretan cohort survivors of the Seven Countries Study (SCS) at 2010 and to compare them with those of survivors assessed in 2000, as well as with literature data on male Cretans at 1965.

We analysed data concerning the gluteal adipose-tissue fatty acids (analysed by GC) from three studies.

The island of Crete (rural areas and the city of Heraklion).

Twenty-two of the 2010 SCS survivors aged 90 years and over; seventy-eight men aged 80 years of the 2000 SCS survivors; and 280 men assessed in 1965.

In comparison to 1965 and 2000, the SCS survivors in 2010 had a higher amount of 18:1n-9 (P<0·05) in their gluteal adipose tissue and a lower amount of PUFA (P<0·05). On the other hand, a constant decrease in adipose-tissue 14:1n-5 and 16:1n-7 was recorded between 1965 and 2010 (P<0·001), and between 2000 and 2010 (P<0·05), while 18:2n-6 appeared to decrease between the 1965 and 2010 assessments (P<0·001).

Comparison with a 1965 representative Cretan sample and 2000 SCS survivors indicated an increased concentration of oleic acid (known for its protective role against mortality) and a decreased concentration of PUFA (known for their susceptibility to oxidation) in our surviving sample at 2010. These changes may reflect internal physiological processes due to diet change within these years and/or ageing.

Estimates of fruit and vegetable (FV) consumption vary depending on intake definition, which may be determined by research purpose. Researchers have used two methods to evaluate intake: epidemiological and behavioural. The present study describes FV intake by adults using epidemiological v. behavioural approaches.

One-day dietary intake data from What We Eat In America, National Health and Nutrition Examination Survey 2009–2012 were used. Sample weights were used to produce nationally representative estimates. FV intake (in cup-equivalents (CE)) was estimated using the Food Patterns Equivalents Database. The epidemiological method considered all FV after disaggregating foods and beverages. The behavioural method included foods that provided at least 0·2 CE FV per 100 g, and excluded sources high in fat, added sugar and Na.

Nationally representative survey of the US population.

Adults (n 10 563) aged ≥20 years.

For epidemiological v. behavioural, fruit intake was 1·1 v. 1·0 CE for males and 1·0 v. 0·9 CE for females. Vegetable intake was 1·8 v. 1·1 CE for males and 1·5 v. 1·0 CE for females.

The definition of FV intake affects estimates of consumption by the population and is an important consideration when planning and comparing research studies. The method used should align with research goals to assure accurate interpretation and validity of results.

To give an account of provisions in the framework of international human rights and intergovernmental policy agreements in relation to eating at school and discuss how these provisions could be invoked to ensure healthy eating at school.

A review of provisions in the international and European human rights frameworks and policy documents was performed in order to identify evidence and examples of provisions implying responsibilities of the school as a public service provider to ensure healthy eating.

The review of the human rights and policy texts showed that there are a large number of provisions that can be invoked in support of measures at school which can contribute to ensuring healthier eating as well as better education supporting such measures.

The international frameworks of human rights and intergovernmental policy agreements should be invoked and translated into concrete strategies, policies, regulations and accountability mechanisms at national, regional, local and school levels. Ensuring healthy eating should be a top priority among all stakeholders in and around the school environment since it is a good investment in children’s short- and long-term health and educational achievements.

To investigate (i) associations between adolescents’ frequency of breakfast and family functioning (close relations to parents, quality of family communication and family support) and (ii) if any observed associations between breakfast frequency and family functioning vary by sociodemographic factors.

School-based cross-sectional study. Students completed a web-based questionnaire. Associations were estimated by multilevel multivariate logistic regression.

Danish arm of the Health Behaviour in School-aged Children study, 2014.

Adolescents aged 13 and 15 years (n 3054) from a random sample of forty-one schools.

Nearly one-quarter of the adolescents had low breakfast frequency. Low breakfast frequency was associated with low family functioning measured by three dimensions. The OR (95 % CI) of low breakfast frequency was 1·81 (1·40, 2·33) for adolescents who reported no close relations to parents, 2·28 (1·61, 3·22) for adolescents who reported low level of quality of family communication and 2·09 (1·39, 3·15) for adolescents who reported low level of family support. Joint effect analyses suggested that the odds of low breakfast frequency among adolescents with low family functioning compared with high family functioning were highest among adolescents being girls, immigrants and living in other than a traditional family structure.

Low breakfast frequency was associated with low family functioning measured by close relations to parents, quality of family communication and family support. Further, analyses suggested that the associations were more pronounced among girls, immigrants and adolescents from other family structure than traditional. The study highlights the importance of the family setting in promoting regular breakfast frequency among adolescents.

Nutritional status during childhood plays an important role in the human life cycle. The present study examined the prevalence trends in different grades of nutritional status (thinness, normal weight, overweight and obesity) among children and adolescents in Shandong, China.

Data for the study were obtained from six cross-sectional surveys of schoolchildren carried out in 1985, 1995, 2000, 2005, 2010 and 2014. Height and weight of all children were measured; BMI was calculated from their height and weight. International BMI cut-offs were used to define thinness, overweight and obesity.

Shandong Province, China.

A total of 56 045 students aged 7–18 years were included in the current analysis.

In the past 29 years, the prevalence of thinness decreased from 18·22 % and 23·45 % in 1985 to 7·18 % and 9·49 % in 2014 for boys and girls, respectively. Conversely, the prevalence of combined overweight and obesity increased from 1·79 % and 1·66 % in 1985 to 31·12 % and 20·11 % in 2014 for boys and girls, respectively.

The nutritional profile of Shandong children and adolescents had an obvious change over the past 29 years. Special attention should be paid to controlling the rapid rise of childhood overweight and obesity.

Dietary guidelines are important education and policy tools to address local nutrition concerns. The current paper presents a comparative analysis of nutrition messages from three Spanish-speaking Caribbean countries (Cuba, Puerto Rico and Dominican Republic) to explore how these dietary guidelines address common public health nutrition concerns, contextualized in different changing food environments and food culture similarities.

Qualitative, comparative analysis of current dietary guideline documents and key recommendations.

Key recommendations were categorized into sixteen themes (two diet-based, ten food-based and four ‘other’). Only the Cuban dietary guidelines included diet-based key recommendations. Of the ten food-based key recommendations, only four themes overlapped across the three dietary guidelines (the encouragement of fruits and vegetables, addressing protein sources and fat). Other overlaps were found between dietary guideline pairs, except between Cuba and Puerto Rico. Further analysis revealed differences in levels of specificity and acknowledgement of local dietary patterns and issues, as well as the need to revise the guidelines to account for current scientific advances.

The present study underscored the importance of context in the framing of dietary advice and the influence of national socio-economic and political situations on nutrition policy and education efforts. The results contribute to inform efforts to improve nutrition communication in the region and among migrant communities.

According to most prospective studies, being underweight (BMI<18·5 kg/m2) is associated with significantly higher mortality than being of normal weight, especially among smokers. We aimed to explore in a generally lean population whether being underweight is significantly associated with increased all-cause mortality.

Prospective cohort study.

Korea Medical Insurance Corporation study with 14 years of follow-up.

After excluding deaths within the first 5 years of follow-up (1993–1997) to minimize reverse causation and excluding participants without information about smoking and health status, 94 133 men and 48 496 women aged 35–59 years in 1990 were included.

We documented 5411 (5·7 %) deaths in men and 762 (1·6 %) in women. Among never smokers, hazard ratios (HR) for underweight individuals were not significantly higher than those for normal-weight individuals (BMI=18·5–22·9 kg/m2): HR=0·87 (95 % CI 0·41, 1·84, P=0·72) for underweight men and HR=1·12 (95 % CI 0·76, 1·65, P=0·58) for underweight women. Among ex-smokers, HR=0·86 (95 % CI 0·38, 1·93, P=0·72) for underweight men and HR=3·77 (95 % CI 0·42, 32·29, P=0·24) for underweight women. Among current smokers, HR=1·60 (95 % CI 1·28, 2·01, P<0·001) for underweight men and HR=2·07 (95 % CI 0·43, 9·94, P=0·36) for underweight women.

The present study does not support that being underweight per se is associated with increased all-cause mortality in Korean men and women.

Taxation of unhealthy food is considered a regulation tool to improve diets. In 2011 Denmark introduced a tax on saturated fat in food products, the first country in the world to do so. The objective of the present paper is to investigate the effects of the tax on consumers’ intake of saturated fat within three different types of food product group: minced beef, regular cream and sour cream.

We use an augmented version of the Linearized Almost Ideal Demand System (LAIDS) functional form for econometric analysis, allowing for tax-induced structural breaks.

Data originate from one of the largest retail chains in Denmark (Coop Danmark) and cover January 2010 to October 2012, with monthly records of sales volume, sales revenue and information about specific campaigns from 1293 stores.

The Danish fat tax had an insignificant or small negative effect on the price for low- and medium-fat varieties, and led to a 13–16 % price increase for high-fat varieties of minced beef and cream products. The tax induced substitution effects, budget effects and preference change effects on consumption, yielding a total decrease of 4–6 % in the intake of saturated fat from minced beef and regular cream, and a negligible effect on the intake from sour cream.

The Danish introduction of a tax on saturated fat in food in October 2011 had statistically significant effects on the sales of fat in minced beef and cream products, but the tax seems to have reduced the beyond-recommendation saturated fat intake to only a limited extent.

The present work is aimed at meta-analysing validity studies of FFQ for adolescents, to investigate their overall accuracy and variables that can affect it negatively.

A meta-analysis of sixteen original articles was performed within the ASSO Project (Adolescents and Surveillance System in the Obesity prevention).

The articles assessed the validity of FFQ for adolescents, compared with food records or 24 h recalls, with regard to energy and nutrient intakes.

Pearson’s or Spearman’s correlation coefficients, means/standard deviations, kappa agreement, percentiles and mean differences/limits of agreement (Bland–Altman method) were extracted. Pooled estimates were calculated and heterogeneity tested for correlation coefficients and means/standard deviations. A subgroup analysis assessed variables influencing FFQ accuracy.

An overall fair/high correlation between FFQ and reference method was found; a good agreement, measured through the intake mean comparison for all nutrients except sugar, carotene and K, was observed. Kappa values showed fair/moderate agreement; an overall good ability to rank adolescents according to energy and nutrient intakes was evidenced by data of percentiles; absolute validity was not confirmed by mean differences/limits of agreement. Interviewer administration mode, consumption interval of the previous year/6 months and high number of food items are major contributors to heterogeneity and thus can reduce FFQ accuracy.

The meta-analysis shows that FFQ are accurate tools for collecting data and could be used for ranking adolescents in terms of energy and nutrient intakes. It suggests how the design and the validation of a new FFQ should be addressed.

To compare the performance of mid-upper arm circumference (MUAC) against weight-for-height Z-score (WHZ) for predicting inpatient deaths in children under 5 years of age.

Diagnostic test accuracy study.

Paediatric emergency department of a tertiary care hospital catering to semi-urban and rural population in Delhi, India.

Hospitalized children (n 1663) aged 6 months to 5 years, for whom discharge outcome was available, were consecutively recruited over 14 months. MUAC (cm), weight (kg) height (cm), clinical details and the outcome were recorded. MUAC (index test) was compared with WHZ based on the WHO growth standards (reference test) for predicting the outcome.

One hundred and twenty-four (7 %) children died during hospital stay. Both MUAC < 11·5 cm (adjusted OR (95 % CI): 3·7 (2·43, 5·60), P<0·001) and WHZ<−3 (2·0 (1·37, 2·99), P<0·001) served as independent predictors of inpatient mortality. However, MUAC was a significantly better predictor of mortality compared with WHZ in terms of area under the receiver-operating characteristic curve (MUAC=0·698, WHZ=0·541, P<0·001). MUAC<11·5 cm had the best trade-off of sensitivity and specificity for predicting inpatient mortality. A combination of WHZ<−3 and/or MUAC<11·5 cm did not significantly improve the predictive value over that of MUAC/WHZ, assessed individually.

MUAC<11·5 cm is a better predictor of mortality in hospitalized under-5 children, as compared with WHZ<−3. It should be measured in all emergency settings to identify the children at higher risk of death.
