To describe trends across the intake distribution of total, manufactured and homemade sugar-sweetened beverages (SSB) from 1999 to 2012, focusing on high SSB consumers and on changes by socio-economic status (SES) subgroup.

We analysed data from one 24 h dietary recall from two nationally representative surveys. Quantile regression models at the 50th, 75th and 90th percentiles of energy intake distribution of SSB were used.

1999 Mexican National Nutrition Survey and 2012 Mexican National Health and Nutrition Survey.

School-aged children (5–11 years) and women (20–49 years) for trend analyses (n 7718). Population aged >1 year for 2012 (n 10 096).

Over the 1999–2012 period, there were significant increases in the proportion of total and manufactured SSB consumers (5·7 and 10·7 percentage points), along with an increase in per-consumer SSB energy intake, resulting in significant increases in per-capita total SSB energy intake (142, 247 and 397 kJ/d (34, 59 and 95 kcal/d) in school-aged children and 155, 331 and 456 kJ/d (37, 79 and 109 kcal/d) in women at the 50th, 75th and 90th percentile, respectively). Total and manufactured SSB intakes increased sharply among low-SES children but remained similar among high-SES children during this time span.

Large increases in SSB consumption were seen between 1999 and 2012 during this pre-tax SSB period, particularly for the highest consumers. Trends observed in school-aged children are a clear example of the nutrition transition experienced in Mexico. Policies to discourage high intake of manufactured SSB should continue, joined with strategies to encourage water and low-calorie beverage consumption.

To compare the performance of the commonly used 24 h recall (24hR) with the more distinct duplicate portion (DP) as reference method for validation of fatty acid intake estimated with an FFQ.

Intakes of SFA, MUFA, n-3 fatty acids and linoleic acid (LA) were estimated by chemical analysis of two DP and by on average five 24hR and two FFQ. Plasma n-3 fatty acids and LA were used to objectively compare ranking of individuals based on DP and 24hR. Multivariate measurement error models were used to estimate validity coefficients and attenuation factors for the FFQ with the DP and 24hR as reference methods.

Wageningen, the Netherlands.

Ninety-two men and 106 women (aged 20–70 years).

Validity coefficients for the fatty acid estimates by the FFQ tended to be lower when using the DP as reference method compared with the 24hR. Attenuation factors for the FFQ tended to be slightly higher based on the DP than those based on the 24hR as reference method. Furthermore, when using plasma fatty acids as reference, the DP showed comparable to slightly better ranking of participants according to their intake of n-3 fatty acids (0·33) and n-3:LA (0·34) than the 24hR (0·22 and 0·24, respectively).

The 24hR gives only slightly different results compared with the distinctive but less feasible DP, therefore use of the 24hR seems appropriate as the reference method for FFQ validation of fatty acid intake.

This study aimed to dynamically model and quantify expected health effects of four scenarios: (i) a reference scenario with an unchanged fruit and vegetable intake, (ii) the removal of value-added tax (VAT) on fruits and vegetables, (iii) the implementation of a 20 % subsidy on fruits and vegetables and (iv) a guideline scenario with a population-wide fruit and vegetable intake of five portions per day.

Baseline fruit and vegetable intake data was derived from the GEDA 2012 study. We used price elasticities for Germany to calculate the change in fruit and vegetable consumption under the zero VAT and the 20 % subsidy scenario. All scenarios were modelled over a 10-year projection period using DYNAMO-HIA.

Germany.

A projected real-life population.

Cumulated over the 10-year projection period, an estimated 4450 incident ischaemic heart disease (IHD) cases, 7010 stroke cases and 13 960 deaths would be prevented under the zero VAT scenario. Under the 20 % subsidy scenario, 17 990 incident IHD cases, 27 390 stroke cases and 54 880 deaths would be averted. Although this corresponds to only a fraction of the incidents that would occur under the reference scenario, the averted cases translate to 2 % (for the zero VAT scenario) and 9 % (for the 20 % subsidy scenario) of IHD, stroke and death cases that would be prevented if the whole population consumed the recommended five portions of fruits and vegetables per day.

Fiscal policies on fruits and vegetables provide a non-negligible step towards the removal of the health burden induced by low fruit and vegetable intake.

Few studies have been conducted to investigate the influence of recombinant human erythropoietin (rhEPO) on the long-term prognosis of end-stage renal disease (ESRD).

A retrospective cohort study.

The largest regional hospital renowned for haemodialysis in northern Taiwan.

A total of 702 ESRD patients undergoing haemodialysis between 1993 and 2002 were evaluated.

The rate of overall use of rhEPO, vitamin D3 or Fe therapy was 62 %. The 10-year survival rate in patients with rhEPO supplementation was statistically more favourable than that in patients without rhEPO (hazard ratio (HR) = 0·38, 95 % CI 0·30, 0·47, P < 0·0001). Similar findings were noted for patients receiving vitamin D3 (HR = 0·36, 95 % CI 0·21, 0·64, P = 0.0004) and Fe (HR = 0·45, 95 % CI 0·33, 0·61, P < 0·0001). After adjusting for age, education and aetiology, the administration of rhEPO resulted in statistically significant improvements in long-term survival rate either with (HR = 0·30, 95 % CI 0·22, 0·42) or without (HR = 0·48, 95 % CI 0·38, 0·61) combined use of Fe or vitamin D3.

We demonstrated a reduction in long-term mortality related to supplementation therapy with rhEPO, vitamin D3 and Fe. The findings provide a justification for the administration of combined supplement therapy in patients undergoing haemodialysis.

To assess the factors associated with overweight and obesity among women of childbearing age in Brazil.

Cross-sectional study.

Using the National Health Survey (PNS) database, from the year 2013. The socio-economic and demographic factors analysed were age, race/skin colour, region, marital status, education level, employment and family income. Concerning health history, diagnoses of hypertension, diabetes mellitus, high cholesterol, heart attack, stroke, chronic kidney disease, menarche, parity and depression were evaluated. For lifestyle information, health status, alcoholic beverage consumption, smoking and physical activity were included. The outcomes were obesity and overweight. The association of excess weight with socio-economic and demographic factors, health history and lifestyle characteristics was investigated according to the appropriate theoretical–conceptual model for the topic.

The sample size was 17 109 women aged 18–49 years.

The prevalence of women with excess weight was 55·20 %, with 33·26 % being overweight and 21·94 % with obesity. The factors associated with excess weight were age, non-white skin colour, having a partner, family income of up to two minimum wages, menarche before the age of 12, multiparity, diabetes mellitus, depression, hypertension, high cholesterol, stroke and heart attack.

The results showed an association between excess weight and socio-demographic factors, both determinants of general and reproductive health history. Implementation of effective public health policies is necessary to prevent unfavourable outcomes related to the health of women of childbearing age with excess weight.

We describe diet quality by demographic factors and weight status among Barbadian children and examine associations with excess energy intake (EI). A screening tool for the identification of children at risk of excess EI was developed.

In a cross-sectional survey, the Diet Quality Index–International (DQI-I) was used to assess dietary intakes from repeat 24h recalls among 362 children aged 9–10 years. Participants were selected by probability proportional to size. A model to identify excess energy intake from easily measured components of the DQI-I was developed.

Barbados.

Primary-school children in Barbados.

Over one-third of children were overweight/obese, and mean EI for boys (8644 (se 174·5) kJ/d (2066 (se 41·7) kcal/d)) and girls (8912 (se 169·9) kJ/d (2130 (se 40·6) kcal/d)) exceeded the RDA. Children consuming a variety of food groups, more vegetables and fruits, and lower percentage energy contribution from empty-calorie foods showed reduced likelihood of excess EI. Intake of more than 2400 mg Na/d and higher macronutrient and fatty acid ratios were positively related to the consumption of excess energy. A model using five DQI-I components (overall food group variety, variety for protein source, vegetables, fruits and empty calorie intake) had high sensitivity for identification of children at risk of excess EI.

Children’s diet quality, despite low intakes of fruit and vegetables, was within acceptable ranges as assessed by the DQI-I and RDA; however, portion size was large and EI high. A practical model for identification of children at risk of excess EI has been developed.

Rates of premature mortality have been higher in Scotland than in England since the 1970s. Given the known association of diet with chronic disease, the study objective was to identify and synthesise evidence on current and historical differences in food and nutrient intakes in Scotland and England.

A rapid review of the peer-reviewed and grey literature was carried out. After an initial scoping search, Medline, CINAHL, Embase and Web of Science were searched. Relevant grey literature was also included. Inclusion criteria were: any date; measures of dietary intake; representative populations; cross-sectional or observational cohort studies; and English-language publications. Study quality was assessed using the Quality Assessment Tool for Observational Cohort and Cross-sectional Studies. A narrative synthesis of extracted information was conducted.

Fifty publications and reports were included in the review. Results indicated that children and adults in Scotland had lower intakes of vegetables and vitamins compared with those living in England. Higher intakes of salt in Scotland were also identified. Data were limited by small Scottish samples, difficulty in finding England-level data, lack of statistical testing and adjustment for key confounders.

Further investigation of adequately powered and analysed surveys is required to examine more fully dietary differences between Scotland and England. This would provide greater insight into potential causes of excess mortality in Scotland compared with England and suitable policy recommendations to address these inequalities.

Both physical activity (PA) and diet are important contributors to health and well-being; however, there is limited information on the association of these behaviours and whether observed associations differ by weight. The present study aimed to evaluate whether nutrient intake is associated with PA and if this association varies by weight in young adults.

Cross-sectional study to analyse the association between PA and nutrient intake.

Participants were stratified as normal weight (18·5 kg/m2 <BMI <25·0 kg/m2) and overweight/obese (BMI≥25·0 kg/m2). PA level (PAL) was calculated (PAL=total daily energy expenditure/RMR) and used to stratify groups (PAL<1·6, 1·6≤PAL<1·9, PAL≥1·9).

Adults (n 407; age 27·6 (sd 3·8) years, 48 % male), with BMI between 20 and 35 kg/m2, having at least two 24 h diet recalls and at least 5 d (including two weekend days) of valid, objectively measured PA data were included in the analysis.

In normal-weight participants, higher PAL was associated with higher intakes of minerals (except Ca, Fe and Zn), B-vitamins and choline (P for trend <0·05). In the overweight/obese group, higher PAL was associated with higher intakes of fibre, K, Na and Cu (P for trend <0·05). These differences, however, were no longer significant after additionally controlling for total energy intake.

More active young adults have higher intakes of essential micronutrients. The benefits of PA may be predominantly due to a higher overall food intake while maintaining energy balance rather than a healthier diet.

To investigate the ability of each metabolic syndrome (MetS) criterion, defined by the International Diabetes Federation, to predict insulin resistance (IR).

A cross-sectional study. IR was defined as homeostasis model assessment of IR (HOMA-IR) ≥3·04. The MetS criteria considered were TAG ≥ 1·69 mmol/l, HDL cholesterol (HDL-C) <1·29 mmol/l, blood pressure (BP) ≥130/85 mmHg and fasting glucose (FG) ≥5·6 mmol/l.

Busan, South Korea.

Ninety-six apparently healthy Korean women (mean age 42 (sd 10·6) years) with abdominal obesity (waist circumference (WC) ≥80 cm) were studied.

Of the ninety-six obese women, 11 % were insulin-resistant and 33 % fulfilled the criteria for IDF-defined MetS. Glucose and TAG were more likely to predict IR than BP and HDL-C when assessed using receiver-operating characteristic curves, multiple regression and multiple logistic regression analyses. Of the variation in HOMA-IR, TAG, FG, WC and age explained 42 %. High FG was independently associated with the presence of IR (OR = 8·6, 95 % CI 1·8, 41·8) even after adjusting for other components of MetS. The positive predictive value and positive likelihood ratio to detect IR were the highest for the FG criterion (33 % and 3·9, respectively), followed by TAG (28 %, 3·0), BP (19 %, 1·8) and HDL-C criteria (18 %, 1·7). The IDF definition of MetS exhibited a positive predictive value of 29 % and a positive likelihood ratio of 3·1.

Of the MetS criteria, high FG and high TAG seem to be more suitable for identifying obese women with IR than high BP and low HDL-C.

This study aimed to develop and validate protein energy malnutrition (PEM) screening tool for older adults in public residential homes, and to test its practicality.

This cross-sectional study consisted of two phases: tool development/validation and tool practicality evaluation. In Phase 1, the questionnaire was developed based on literature review and tested for content validity. Older residents were interviewed using this questionnaire to identify potential PEM risk factors. A 24-h recall was used to collect dietary data, and body composition and serum albumin were measured. In Phase 2, practicality of new PEM screening tool was evaluated by intended users. Data were analysed by χ2 test, Fisher’s exact test, t-test, Mann–Whitney U test and multiple logistic regression. Akaike Information Criterion (AIC) was used to estimate the best fit model.

Four public residential homes in central region, Thailand.

249 older residents residing in public residential homes and eight intended users.

26·9 % had PEM (serum albumin <3·5 g/dl). According to multiple logistic regression and AIC values, PEM predictors were having pressure ulcer, experiencing significant weight loss and taking ≥ 9 types of medicine daily. These predictors were included in PEM screening tool. Regarding the tool performance test, area under the ROC curve was 0·8 (P < 0·001) with sensitivity and specificity of 83·9 and 45·5 %, respectively. For its practicality, eight intended users reported that it was useful and easy to use.

New screening tool may be capable of identifying PEM in older residents, and further testing is required before being recommended for use.

Optimal nutrition for hospital patients is crucial and routine monitoring of patients’ nutrient intake is imperative. However, personalised monitoring and customised intervention using traditional methods is challenging and labour-intensive, consequently it is often neglected in hospital settings. The present pilot study aimed to examine the reliability and validity of the Dietary Intake Monitoring System (DIMS) against the weighed food method (WFM).

The DIMS 2.0 is composed of an integrated digital camera, weighing scale, radio-frequency identification sensor and WIFI connection for real-time image and weight dietary data acquisition and analysis. The DIMS equipment was used to collect data for a paired set of meals both before and after meal consumption at lunchtime.

Odense University Hospital, Denmark.

Photos and weights of seventeen patient meals were captured.

The results showed a significant correlation between DIMS and WFM for energy (r=0·99, P<0·01) and protein intake (r=0·98, P<0·01). Intraclass correlation coefficients (ICC) revealed a high degree of agreement among the four non-trained assessors for estimates of portion size of each food item before (0·88, P<0·01) and after consumption (0·99, P<0·01). The ICC for energy and protein intake were 0·99 (P<0·01) and 0·99 (P<0·01), respectively. Bland–Altman plots revealed no systematic bias.

Considering the huge benefits associated with routine monitoring, technological advances have made it possible to develop a novel, easy-to-use DIMS that, according to the findings, is a valid alternative for use in hospital settings.

To evaluate the effectiveness of a social marketing intervention in enhancing knowledge, attitudes and practice (KAP) related to consumption of vitamin A-fortified oil.

The intervention employed community events, distribution of educational materials and radio broadcasts. The intervention was assessed in a quasi-experimental non-equivalent control group study design by collecting information on KAP regarding vitamin A-fortified oil consumption before and after 9 months of a 13-month intervention.

Six districts in Manyara and Shinyanga regions in Tanzania were non-randomly selected as the intervention districts and two districts served as the control districts.

At baseline, 568 lactating mothers with children aged <5 years were randomly selected from the intervention and control districts. Of these, 494 mothers were followed up at endline.

After 9 months of intervention, knowledge of fortification and actual consumption of adequately fortified oil were significantly higher in the intervention districts compared with the control districts (P <0·05). Knowledge of the health benefits of vitamin A improved significantly from about 33 to 45 % in both the intervention and control districts. The major sources of information for women were health clinics and community health workers (CHW).

The study showed that a social marketing intervention is effective in improving KAP regarding fortified oil consumption at the household level. Clinics and CHW are channels that should be prioritized when communicating health messages, particularly those targeting women.

This study aims to analyse the differences, with regard to socio-cultural characteristics and dietary habits, between low and high consumers of yoghurt and other fermented dairy product desserts, and the nutritional significance of these differences.

We analysed the diet of a healthy population (4–65 years), using the 24-hour recall method, on three non-consecutive days. The participants were grouped by age and sex and were also divided into tertiles on the basis of yoghurt consumption. We compared energy and nutrient intakes, educational level and socio-economic status in the low consumption (LC) group and the high consumption (HC) group.

In general there were no significant differences in energy intake or nutritional profile between LC and HC groups. The only significant difference was in the percentage of energy provided by lipids, which was significantly lower in HC women, possibly due to the high number of women in this group who consumed low-fat yoghurt. There were significant differences in the distribution of HC and LC subjects according to the three educational levels (P < 0.05) but n according to socio-economic status.

The fact of being a high consumer of fermented dairy products took place in the framework of other dietary changes that compensated for this high consumption, resulting in the absence of significant differences in energy intake and nutritional profile between HC and LC subjects. The only exception was found in women who consumed low-fat dairy products. There was a relationship between high consumption of fermented dairy products and educational level.

To compare the frequency and healthfulness of foods being advertised to children and adolescents in four countries of WHO European region.

Cross-sectional quantitative study, guided by an adapted version of the WHO protocol. All recorded food advertisements were categorised by categories and as either ‘permitted’ or ‘not permitted’ for advertising to children in accordance with WHO Regional Office for Europe Nutrient Profile Model.

Four countries: Russia, Turkey, Kazakhstan and Kyrgyzstan

TV channels most popular among children and adolescents

Analysis included 70 d of TV broadcasting for all channels, during which time there were 28 399 advertisements. The mean number of advertisements per hour varied from eleven in Turkey and Kazakhstan to eight and two in Russia and Kyrgyzstan. In all countries, the majority of the food and beverages advertised should not be permitted for advertising to children according to the WHO Nutrient Profile Model. The mean number of non-permitted food and beverage advertisements per hour was high in Turkey and Kazakhstan (8·8 and 8·5 ads) compared with Russia (5·1) and Kyrgyzstan (1·9). Turkey was the only country where nutritional information was fully available, and no values were missing that prevented coding for some product categories.

Results revealed that children and adolescents in four countries are exposed to a considerable volume of food and beverage advertisements, including sugary products on broadcast television. As such, policymakers should consider protecting youth by developing regulations to restrict these marketing activities within media popular with children.

To investigate the effect of different feeding patterns on the occurrence of diseases among infants.

Data on socio-economic status, feeding patterns before 6 months (exclusive breast-feeding (EBF); mixed feeding with breast milk and formula (MBF); exclusive formula-feeding (EFF)) and illness of infants were collected via face-to-face interviews. The proportions of infants who had ever been ill or hospitalized and their potential influence factors were investigated.

Eight large cities in China.

Infants (n 1654) aged 0–11·9 months were recruited from hospitals.

For infants aged 0–2·9 months, the percentage who had been ill was 19·2 %, 24·1 % and 26·3 % among the EBF, MBF and EFF groups, respectively. For those aged 3–5·9 and 6–11·9 months, the corresponding percentages were 41·6 %, 45·6 % and 51·0 %, and 67·0 %, 73·4 % and 67·7 %. Respiratory disease was the most common reported illness and cause of hospitalization. The risks of having (total) illness, diarrhoea and respiratory disease increased significantly with age, but not allergic disease. Compared with EBF, MBF and EFF infants had significantly higher risks of having illnesses except for allergic disease, and feeding patterns were not related to hospitalization. Low birth weight, middle family income and low level of mother’s education also increased the risk of illness.

A protective effect of EBF against total illness in urban Chinese infants was found. An increasing trend with age was observed among the percentages of infants who had been ill or had diarrhoea or respiratory disease, but not allergic disease.

We wanted to identify factors related to dietary behavioural change among impoverished pregnant women in the face of nutrition education and counselling, describing what creates an enabling environment and barriers for dietary change.

We used qualitative data from a cluster-randomised maternal education trial and conducted a thematic analysis using a social ecological framework to describe the factors that influenced dietary adherence.

Mangochi district in rural Malawi.

We interviewed ten pregnant women and conducted four sets of focus group discussions with twenty-two significant family members (husbands and mothers-in-law) and twelve counsellors.

The participants’ experiences showed that the main barriers of adherence to the intervention were taste, affordability and poverty. The use of powders and one-pot dishes, inclusion of both women and significant family members and a harmonisation with local food practices enabled adherence to the intervention. We found it crucial to focus the dietary education and counselling intervention on locally available ingredients and food processing methods.

Use of contextualised food-based solutions to combat maternal malnutrition was observed to be relatively cheap and sustainable. However, there is need for more research on local foods used as nutrition supplements. We suggest that investments need to be directed not only to nutrition education and counselling but also to the enabling factors that enhance adherence. The original cluster-randomised controlled trial was registered with Clinical trials.gov ID: NCT03136393.

To assess the association between the risk of malnutrition, as estimated by the Patient-Generated Subjective Global Assessment (PG-SGA) numerical scores, and adverse outcomes in oncology patients.

Systematic review and meta-analysis.

A comprehensive search was conducted in PubMed, Web of Science, Embase, CKNI, VIP, Sinomed and Wanfang databases. Studies that examined the association between the risk of malnutrition, as estimated by the PG-SGA numerical scores, and overall survival (OS) or postoperative complications in oncology patients were included. Patients were classified as low risk (PG-SGA ≤ 3), medium risk (PG-SGA 4–8) and high risk of malnutrition (PG-SGA > 8).

Nineteen studies reporting on twenty articles (n 9286 patients).

The prevalence of medium and high risk of malnutrition ranged from 16·0 % to 71·6 %. A meta-analysis showed that cancer patients with medium and high risk of malnutrition had a poorer OS (adjusted hazard ratios (HR) 1·98; 95 % CI 1·77, 2·21) compared with those with a low risk of malnutrition. Stratified analysis revealed that the pooled HR was 1·55 (95 % CI 1·17, 2·06) for medium risk of malnutrition and 2·65 (95 % CI 1·90, 3·70) for high risk of malnutrition. Additionally, the pooled adjusted OR for postoperative complications was 4·65 (95 % CI 1·61, 13·44) for patients at medium and high risk of malnutrition.

The presence of medium and high risk of malnutrition, as estimated by the PG-SGA numerical scores, is significantly linked to poorer OS and an increased risk of postoperative complications in oncology patients.

The prevalence of obesity has increased in the last decades in the Western world. The aim of the present study was to examine the association between risk-taking behaviour in adolescence and adult obesity in men and women. Furthermore, we wished to describe social differences in obesity in Denmark.

Two population-based questionnaire studies (2004–2005 and 2006–2007) were used to collect information on weight and height, sociodemographic factors and factors regarding risk-taking behaviour during adolescence. Data were analysed using multivariate logistic regression.

Denmark.

Individuals aged 18–45 years (men: n 22 827, participation rate 71·0 %; women: n 20 870, participation rate 81·4 %).

The prevalence of overweight and obesity was respectively 37·8 % and 10·6 % in men and 20·1 % and 9·7 % in women. In both sexes, obesity was found to be associated with older age, low level of schooling and living outside the capital centre. In relation to risk-taking behaviour, young age (≤13 years) at first intercourse significantly increased the odds of being obese in adulthood (men: OR = 1·34, 95 % CI 1·04, 1·71; women: OR = 1·66, 95 % CI 1·27, 1·99). In women specifically, young age at start drinking alcohol (≤12 years) was associated with obesity.

Sociodemographic factors, in particular age, level of schooling and area of residence, are associated with obesity in both men and women. Risk-taking behaviour during adolescence seems to cluster in both obese men and obese women, however most convincingly in women.
