To describe diet quality (Healthy Eating Index 2010 (HEI-2010) and Healthy Eating Index 2015 (HEI-2015)) according to self-reported cannabis use among the National Health and Nutrition Examination Survey (NHANES) adult participants.

Utilizing cross-sectional data, we assessed diet quality with up to two 24-h diet recalls from NHANES participants. Usual intakes were estimated via the multivariate Markov Chain–Monte Carlo method. Diet quality scores were compared among never users, previous users and current users of cannabis.

NHANES surveys from 2005 to 2016.

Adult NHANES participants (17 855) aged 20–59 years with valid data for dietary recalls and drug use questionnaires.

Current adult cannabis users (ages 20–59 years) had significantly lower total diet quality (HEI-2010) scores (51·8 ± 0·7) compared with previous (56·2 ± 0·4) and never users (57·7 ± 0·4). Similar differences in total and individual HEI-2015 scores were observed. For the HEI-2015 scores, cannabis users had a significantly higher (better) sodium scores (4·1 ± 0·2) compared with never users (3·3 ± 0·1) and previous users (3·2 ± 0·1). Cannabis users scored lower compared with never users on total vegetables (3·1 ± 0·1 v. 3·7 ± 0·0), total fruit (2·1 ± 0·1 v. 3·0 ± 0·1) and whole fruit (2·2 ± 0·1 v. 3·3 ± 0·1) for the HEI-2015 index.

Current cannabis users’ usual intakes reflect lower diet quality compared with never or previous users, particularly lower subcomponent scores of total vegetables, greens and beans, total fruit and whole fruit. Cannabis users should increase their intake of fruit and vegetables to improve overall diet quality.

To assess the association between patterns of nutrient intake and metabolic syndrome (MetS) in a large sample of Iranian adults.

Baseline data from the Shahedieh cohort study were used in the current cross-sectional study. Dietary intakes were assessed through the use of a validated semi-quantitative FFQ. Nutrient patterns (NP) were derived using factor analysis. The MetS was defined according to criteria introduced from the National Cholesterol Education Program Adult Treatment Panel III, modified for Iranian adults.

Yazd, Iran.

A total of 7325 Iranian adults aged between 30 and 75 years.

Three NP were identified. A significant positive association was found between adherence to semi-plant NP (characterised by the high intakes of P; vitamins B1, B3, B6 and B5; Se; Mg; Fe; protein; Cr; Cu; fibre; biotin; Mn; Zn and Na) and odds of MetS (OR 1·68, 95 % CI 1·43, 1·98). However, after adjusting for potential confounders, this association became non-significant. In addition, after taking potential confounders into account, individuals in the highest quintile of the semi-animal NP, rich in Ca; K; vitamins B2, B12, A, D, K and C; SFA; dietary cholesterol and trans-fatty acid, were 26 % more likely to have MetS compared with those in the lowest quintile (OR 1·26, 95 % CI 1·05, 1·51). No significant association was seen between adherence to the high-carbohydrate/low-fat NP and odds of MetS.

We found that adherence to a semi-animal NP was associated with increased odds of MetS.

No recent original studies on the pattern of diet are available for Saudi Arabia at the national level. The present study was performed to describe the consumption of foods and beverages by Saudi adults.

The Saudi Health Interview Survey (SHIS) was conducted in 2013. Data were collected through interviews and anthropometric measurements were done. A diet history questionnaire was used to determine the amount of consumption for eighteen food or beverage items in a typical week.

The study was a household survey in all thirteen administrative regions of Saudi Arabia.

Participants were 10 735 individuals aged 15 years or older.

Mean daily consumption was 70·9 (se 1·3) g for fruits, 111·1 (se 2·0) g for vegetables, 11·6 (se 0·3) g for dark fish, 13·8 (se 0·3) g for other fish, 44·2 (se 0·7) g for red meat, 4·8 (se 0·2) g for processed meat, 10·9 (se 0·3) g for nuts, 219·4 (se 5·1) ml for milk and 115·5 (se 2·6) ml for sugar-sweetened beverages. Dietary guideline recommendations were met by only 5·2 % of individuals for fruits, 7·5 % for vegetables, 31·4 % for nuts and 44·7 % for fish. The consumption of processed foods and sugar-sweetened beverages was high in young adults.

Only a small percentage of the Saudi population met the dietary recommendations. Programmes to improve dietary behaviours are urgently needed to reduce the current and future burden of disease. The promotion of healthy diets should target both the general population and specific high-risk groups. Regular assessments of dietary status are needed to monitor trends and inform interventions.

To describe the diet costs of adults in the National Diet and Nutrition Study (NDNS) and explore patterns in costs according to sociodemographic indicators.

Cross-sectional diet diary information was matched to a database of food prices to assign a cost to each food or non-alcoholic beverage consumed. Daily diet costs were calculated, as well as costs per 10 MJ to improve comparability across differing energy requirements. Costs were compared between categories of sociodemographic variables and health behaviours. Multivariable regression assessed the effects of each variable on diet costs after adjustment.

The NDNS is a rolling dietary survey, recruiting a representative UK sample each year. The study features data from 2008–2010.

Adults aged 19 years or over were included. The sample consisted of 1014 participants.

The geometric mean daily diet cost was £2·89 (95 % CI £2·81, £2·96). Energy intake and daily diet cost were strongly associated. The mean energy-adjusted cost was £4·09 (95 % CI £4·01, £4·18) per 10 MJ. Energy-adjusted costs differed significantly between many subgroups, including by sex and household income. Multivariable regression found significant effects of sex, qualifications and occupation (costs per 10 MJ only), as well as equivalized household income, BMI and fruit and vegetable consumption on diet costs.

This is the first time that monetary costs have been applied to the diets of NDNS adults. The findings suggest that certain subgroups in the UK – for example those on lower incomes – consume diets of lower monetary value. Observed differences were mostly in the directions anticipated.

Concordance of nutritional research priorities with the related burden of disease is essential to develop cost-effective interventions to address the nutritional problems of populations. The present study aimed to evaluate whether nutrition research priorities are in agreement with the population’s nutritional problems in Latin America.

The epidemiological profile was contrasted with the research priorities and research produced by academic institutions for each country. Qualitative analysis of research production by type of contribution to problem solving was also conducted.

Nine Latin American countries.

Obesity (high body mass index (BMI)) and micronutrient deficiencies (anaemia) emerged as key problems, followed by stunting, breast-feeding/lactation and low birth weight. Wasting in children and women (low BMI) was uncommon. Concordance of ranked research priorities with the epidemiological profile of the country was generally good for nutrition-related chronic diseases, micronutrients and low birth weight, but not for undernutrition, stunting and breast-feeding. Studies on the efficacy and effectiveness of interventions were uncommon.

The present research agenda insufficiently supports the goal of public health nutrition, which is to ensure the implementation of cost-effective nutrition programmes and policies. A more rational approach to define research priorities is needed.
