The present study aimed to develop and validate a questionnaire assessing perceived food environment in a French-Canadian population.

A questionnaire, the Perceived Food Environment Questionnaire, was developed assessing perceived accessibility to healthy (nine items) and unhealthy foods (three items). A pre-test sample was recruited for a pilot testing of the questionnaire. For the validation study, another sample was recruited and completed the questionnaire twice. Exploratory factor analysis was performed on the items to assess the number of factors (subscales). Cronbach’s α was used to measure internal consistency reliability. Test–retest reliability was assessed with Pearson correlations.

Online survey.

Men and women from the Québec City area (n 31 in the pre-test sample; n 150 in the validation study sample).

The pilot testing did not lead to any change in the questionnaire. The exploratory factor analysis revealed a two-subscale structure. The first subscale is composed of six items assessing accessibility to healthy foods and the second includes three items related to accessibility to unhealthy foods. Three items were removed from the questionnaire due to low loading on the two subscales. The subscales demonstrated adequate internal consistency (Cronbach’s α=0·77 for healthy foods and 0·62 for unhealthy foods) and test–retest reliability (r=0·59 and 0·60, respectively; both P<0·0001).

The Perceived Food Environment Questionnaire was developed for a French-Canadian population and demonstrated good psychometric properties. Further validation is recommended if the questionnaire is to be used in other populations.

High sugar-sweetened beverage (SSB) intake has been shown to correlate with a higher risk for CVD and metabolic disorders, while the association between SSB intake and the risk of metabolic syndrome (MetS) remains unclear. The present study aimed to explore the association between SSB intake and MetS among children and adolescents in urban China.

A cross-sectional study involving 7143 children and adolescents was conducted in urban China. MetS definition proposed by the International Diabetes Federation was adopted. Data on SSB intake, diet, physical activity and family environment factors were obtained through questionnaires. Logistic regression models with multivariable adjustment were adopted to analyse the association between SSB intake and the risk of MetS and its components.

Primary and secondary schools in three urban cities of China.

Children and adolescents (n 5258) aged 7–18 years.

Among the participants, 29·9 % of them had high SSB intake (at least 0·3 servings/d) and the overall MetS prevalence was 2·7 %. Participants with high SSB intake were at higher risk for MetS (OR = 1·60; 95 % CI 1·03, 2·54) and abdominal obesity (OR = 1·55; 95 % CI 1·28, 1·83) compared with their counterparts with no SSB intake (0 servings/d).

High SSB intake is significantly associated with increased MetS and abdominal obesity risk among children and adolescents in urban China. These results suggest that strong policies focusing on controlling SSB intake might be effective in preventing MetS and abdominal obesity.

Foods prepared outside of the home have been linked to less-than-ideal nutrient profiles for health. We examine whether the locations where meals are prepared and consumed are associated with socio-economic predictors among women.

A cross-sectional study using self-reported data. We examined multiple locations where meals are prepared and consumed: (i) at home; (ii) fast food eaten at home; (iii) fast food eaten at the restaurant; (iv) total fast food; (v) non-fast-food restaurant meals eaten at home; (vi) non-fast-food restaurant meals eaten at the restaurant; and (vii) all non-fast-food restaurant meals. Multilevel logistic regression was used to determine whether frequent consumption of meals from these sources varied by level of education, occupation, household income and area-level disadvantage.

Metropolitan Melbourne, Australia.

A total of 1328 women from forty-five neighbourhoods randomly sampled for the SocioEconomic Status and Activity in Women study.

Those with higher educational qualifications or who were not in the workforce (compared with those in professional employment) were more likely to report frequent consumption of meals prepared and consumed at home. High individual- and area-level socio-economic characteristics were associated with a lower likelihood of frequent consumption of fast food and a higher likelihood of frequent consumption of meals from non-fast-food sources. The strength and significance of relationships varied by place of consumption.

The source of meal preparation and consumption varied by socio-economic predictors. This has implications for policy makers who need to continue to campaign to make healthy alternatives available in out-of-home food sources.

This paper examines socioeconomic, demographic, epidemiological and nutrition changes that have occurred in Chile in the last decades using concepts of epidemiological and nutrition transition, and discusses policies related to nutrition.

This is a descriptive, population-based study to analyse changes in the Chilean diet and nutrition situation including some of the main demographic, socioeconomic and epidemiological variables. Data came from the FAO, the National Institute of Statistics, the Ministry of Health and national surveys.

In Chile, the epidemiological and nutrition situation shifted from a pretransition stage with high rates of undernutrition to a post-transition stage with increasing rates of obesity in all groups aged less than 20 years. However, changes were not accompanied by modifications in nutrition policy, which had been successful in reducing undernutrition. Despite changes in diet to a ‘western’ diet and in nutritional status of the population from undernutrition to obesity, food and nutrition programmes have been maintained unaltered. Governmental and university organizations were created in 1994 and 1995 to address the current food and nutrition problems. The accomplishments of these institutions have been the elaboration of dietary guidelines, reformulating the food and nutrition programmes and the promulgation of the Food Sanitary Regulations for Chile.

Education for the prevention of nutrition excess problems should be a main food and nutrition policy in developing countries.

To assess the contribution of street foods to the energy and nutrient needs of street food vendors.

A cross-sectional descriptive study was conducted. Food intake for the street food vendors was measured using the 24 h recall method and a semi-quantitative FFQ with emphasis on the source of all foods consumed.

Kampala, Jinja and Masaka districts, Uganda.

The study included 225 street food vendors trading in prepared cooked foods.

The majority of vendors (87·6 %) were women with age range of 21–50 years. Traditional dishes were the most commonly prepared foods and classified into main meals, sauces, vegetables and snacks. The food groups consumed most commonly by street food vendors fall under energy-giving and body-building foods (0·26 (sd 0·81)). The mean daily intake of energy from street foods varied between 22·4 % and 25·6 % (2412 kJ). Carbohydrates contributed the highest proportion of energy (70·1 % to 93·4 %), followed by protein (38·6 % to 44·9 %) and fat (21·9 % to 26·3 %). Street food vendors obtained 24·0 % to 32·5 % of their RDA for Ca from street vended foods, with the lowest intake in Jinja (11·2 % to 23·9 %, P < 0·05). Niacin and thiamin intakes from street foods were respectively above 74 % and 150 % of the RDA. The contribution of street foods to the RDA for Zn ranged from 81·9 % to 190·9 %, and from 3·5 % to 4·9 % for retinol. Fe intake from street vended foods was 40·9 % to 49·7 % of the RDA.

Street foods contribute to sources of dietary energy and other nutrients among street food vendors in Uganda.

To determine changes in reported food frequency in adults between 1986 and 1999.

Four consecutive cross-sectional surveys.

Counties of Norrbotten and Västerbotten, Northern Sweden.

The Northern Sweden MONICA (Monitoring of Trends and Determinants in Cardiovascular Disease) population, four independent cross-sectional surveys in 1986, 1990, 1994 and 1999. Randomly selected age-stratified samples of the population aged 25–64 years. Analysis is based on 2982 males and 3087 females who completed an 84-item food-frequency questionnaire.

Between 1986 and 1999, average reported consumption of 3%-fat milk decreased from 42 to 7 intakes month-1 in men and from 28 to 4 intakes month-1 in women. Reported use of 1.5%-fat milk increased from 6 to 27 intakes month-1 in men and from 6 to 24 in women. Monthly intakes of potatoes and root vegetables decreased from 38 to 27 in men and from 39 to 32 in women. Consumption of pasta increased from 4 to 7 intakes month-1 in both sexes. Intakes of solid fats with 80% fat content dropped from 92 to 62 per month in men and from 78 to 52 per month in women, whereas use of 40%-fat spread increased from 12 to 22 intakes month-1 in men and from 5 to 26 in women. Monthly intakes of vegetable oil increased from 3 to 12 in men and from 3 to 15 in women. The percentage of overweight or obese individuals (body mass index >25 kg m-2) increased from 52 to 65% in men and from 41 to 52% in women (P for linear trend in all these changes, <0.001).

Our data indicate reduced consumption of foods with a high content of saturated fats. In spite of that, there is an unbroken trend towards increased obesity.

Vegetarian diets may be associated with low prevalence of autoimmune disease, as observed in rural sub-Saharan Africans. Graves’ disease, an autoimmune disorder, is the most common cause of hyperthyroidism. We studied prevalence of hyperthyroidism according to dietary pattern in a population with a high proportion of vegetarians.

Cross-sectional prevalence study. The association between diet and prevalence of hyperthyroidism was examined using multivariate logistic regression analyses controlling for sociodemographic characteristics and salt use.

The Adventist Health Study-2 conducted in the USA and Canada.

Church members (n 65 981) provided demographic, dietary, lifestyle and medical history data by questionnaire.

The prevalence of self-reported hyperthyroidism was 0·9 %. Male gender (OR=0·32; 95 % CI 0·26, 0·41) and moderate or high income (OR=0·67; 95 % CI 0·52, 0·88 and OR=0·73; 95 % CI 0·58, 0·91, respectively) protected against hyperthyroidism, while obesity and prevalent CVD were associated with increased risk (OR=1·25; 95 % CI 1·02, 1·54 and OR=1·92; 95 % CI 1·53, 2·42, respectively). Vegan, lacto-ovo and pesco vegetarian diets were associated with lower risk compared with omnivorous diets (OR=0·49; 95 % CI 0·33, OR=0·72, 0·65; 95 % CI 0·53, 0·81 and OR=0·74; 95 % CI 0·56, 1·00, respectively).

Exclusion of all animal foods was associated with half the prevalence of hyperthyroidism compared with omnivorous diets. Lacto-ovo and pesco vegetarian diets were associated with intermediate protection. Further study of potential mechanisms is warranted.

To describe dietary patterns by applying cluster analysis and to describe the cluster memberships of European children over time and their association with body composition changes.

The analyses included k-means clustering based on the similarities between the relative frequencies of consumption of forty-three food items and regression models were fitted to assess the association between dietary patterns and body composition changes.

Primary schools and pre-schools of selected regions in Italy, Estonia, Cyprus, Belgium, Sweden, Hungary, Germany and Spain.

Participants (n 8341) in the baseline (2–9 years old) and follow-up (4–11 years old) surveys of the IDEFICS (Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS) study.

Three persistent clusters were obtained at baseline and follow-up. Children consistently allocated to the ‘processed’ cluster presented increased BMI (β=0·050; 95 % CI 0·006, 0·093), increased waist circumference (β=0·071; 95 % CI 0·001, 0·141) and increased fat mass gain (β=0·052; 95 % CI 0·014, 0·090) over time v. children allocated to the ‘healthy’ cluster. Being in the ‘processed’–‘sweet’ cluster combination was also linked to increased BMI (β=0·079; 95 % CI 0·015, 0·143), increased waist circumference (β=0·172; 95 % CI 0·069, 0·275) and increased fat mass gain (β=0·076; 95 % CI 0·019, 0·133) over time v. the ‘healthy’ cluster.

Children consistently showing a processed dietary pattern or changing from a processed pattern to a sweet pattern presented the most unfavourable changes in fat mass and abdominal fat. These findings support the need to promote overall healthy dietary habits in obesity prevention and health promotion programmes targeting children.

To evaluate the effect of school-based nutrition interventions (SBNI) involving schoolchildren and adolescents in sub-Saharan Africa (SSA) on child nutrition status and nutrition-related knowledge, attitudes and behaviour.

A systematic review on published school nutrition intervention studies of randomised controlled trials, controlled clinical trials, controlled before-and-after studies or quasi-experimental designs with control. Nine electronic bibliographic databases were searched. To be included, interventions had to involve changes to the school’s physical and social environments, to the school’s nutrition policies, to teaching curriculum to incorporate nutrition education and/or to partnership with parents/community.

Schools in SSA.

School-aged children and adolescents, aged 5–19 years.

Fourteen studies met our inclusion criteria. While there are few existing studies of SBNI in SSA, the evidence shows that food supplementation/fortification is very effective in reducing micronutrient deficiencies and can improve nutrition status. Secondly, school nutrition education can improve nutrition knowledge, but this may not necessarily translate into healthy nutrition behaviour, indicating that nutrition knowledge may have little impact without a facilitating environment. Results regarding anthropometry were inconclusive; however, there is evidence for the effectiveness of SBNI in improving cognitive abilities.

There is enough evidence to warrant further trials of SBNI in SSA. Future research should consider investigating the impact of SBNI on anthropometry and nutrition behaviour, focusing on the role of programme intensity and/or duration. To address the high incidence of micronutrient deficiencies in low- and middle-income countries, food supplementation strategies currently available to schoolchildren should be expanded.

In a sample of older Japanese American women, we aimed to: (1) describe the most commonly consumed soy foods, (2) estimate dietary soy isoflavone intake, (3) describe characteristics associated with dietary soy isoflavone intake, and (4) compare our estimates with previously published estimates in other Japanese samples.

A 14-item soy food-frequency questionnaire was administered to older Japanese American women and responses were converted to quantitative estimates of soy isoflavones (genistein plus daidzein). Multiple regression was used to examine characteristics associated with dietary soy isoflavone intake, including self-reported lifestyle and cultural factors and dietary intake of various foods ascertained from a semi-quantitative food-frequency questionnaire. To compare our estimates with other samples, a review of the literature was conducted.

Data are from 274 women aged 65+ years, recruited from a longitudinal cohort study of Japanese Americans in King County, Washington State.

The soy foods most commonly consumed were tofu (soybean curd), miso (fermented soybean paste) and aburaage (fried thin soybean curd). The mean intake of dietary soy isoflavones was 10.2 (standard deviation (SD), 12.4) mg day−1, approximately a quarter to a half that of previously published estimates in Japanese samples. Dietary soy isoflavone intake was positively associated with speaking Japanese, the consumption of traditional Japanese dishes (kamaboko, manju and mochi), low-fat/non-fat milk and yellow/red vegetables, vitamin E supplement use, and walking several blocks each day. Dietary soy isoflavone intake was negatively associated with the consumption of butter.

The estimated dietary soy isoflavone intake in Japanese American women living in King County, Washington State was about a quarter to a half that of women living in Japan. Dietary soy isoflavone intake was associated with speaking Japanese and healthy lifestyle and dietary habits.

To update the estimate of mean salt intake for the Australian population made by the Australian Health Survey (AHS).

A secondary analysis of the data collected in a cross-sectional survey was conducted. Estimates of salt intake were made in Lithgow using the 24 h diet recall methodology employed by the AHS as well as using 24 h urine collections. The data from the Lithgow sample were age- and sex-weighted, to provide estimates of daily salt intake for the Australian population based upon (i) the diet recall data and (ii) the 24 h urine samples.

Lithgow, New South Wales, Australia.

Individuals aged ≥20 years residing in Lithgow and listed on the 2009 federal electoral roll.

Mean (95 % CI) salt intake estimated from the 24 h diet recalls was 6·4 (6·2, 6·7) g/d for the Lithgow population compared with a corresponding figure of 6·2 g/d for the Australian population derived from the AHS. The corresponding estimate of salt intake for Lithgow adults based upon the 24 h urine collections was 9·0 (8·6, 9·4) g/d. When the age- and sex-specific estimates of salt intake obtained from the 24 h urine collections in the Lithgow sample were weighted using Australian census data, estimated salt intake for the Australian population was 9·0 (8·6, 9·5) g/d. Further adjustment for non-urinary Na excretion made the best estimate of daily salt intake for both Lithgow and Australia about 9·9 g/d.

The dietary recall method used by the AHS likely substantially underestimated mean population salt consumption in Australia.

A suboptimal diet and nutritional deficiencies can have important influences on health with significant impact among older adults. This study aims to assess the presence of suboptimal dietary intake among older Americans and identify risk and protective factors influencing diet quality.

Cross-sectional secondary analysis.

USA.

A nationally representative sample of 5614 community-dwelling older adults over age 54 in the Health and Retirement Study – Health Care and Nutrition Survey.

Overall, only 10·7 % of respondents had a good quality diet (Healthy Eating Index score 81 and above); the majority had diets considered poor or needing improvement. Less than 50 % of respondents met dietary guidelines and nutritional goals for most individual food groups and nutrients. Respondents with low socio-economic status, fewer psychosocial resources and those who had limited access to healthy food outlets were more likely to have a diet of suboptimal quality.

Efforts to remove identified barriers that put older adults at risk for poor nutrition and to provide resources that increase access to healthy food should be made to encourage healthy eating and enhance diet quality.

To assess the relative validity and reproducibility of the semi-quantitative FFQ (SFFQ) applied in the evaluation of a community intervention study, SoL-Bornholm, for estimating food intakes.

The reference measure was a 4 d estimated food record. The SFFQ was completed two times separated by a 1-month period in order to test reproducibility.

The Capital Region and the Regional Municipality of Bornholm, Denmark.

A total of fifty-four children aged 3–9 years were enrolled in the study.

In terms of validity, the SFFQ generally overestimated intakes compared with the food records, especially for vegetables. For most intakes, the mean difference increased with increasing intake. Gross misclassification was on average higher for energy and nutrients (17 %) than for foods (8 %). Spearman correlation coefficients were significant for twelve out of fourteen intakes, ranging from 0·29 to 0·63 for foods and from 0·12 to 0·48 for energy and nutrients. Comparing the repeated SFFQ administrations, the intakes of the first SFFQ were slightly higher than those of the second SFFQ. Gross misclassification was low for most intakes; on average 6 % for foods and 8 % for energy and nutrients. Intra-class correlations were significant for all intakes, ranging from 0·30 to 0·82 for foods and from 0·46 to 0·81 for energy and nutrients.

The results indicate that the SFFQ gives reproducible estimates. The relative validity of the SFFQ was low to moderate for most intakes but comparable to other studies among children.

To investigate pregnant women's views on infant feeding options recommended for HIV-infected women.

A structured interview survey complemented with focus group discussions.

Antenatal clinics in Moshi urban and rural districts of Tanzania.

Five hundred pregnant women participated in the interview survey and 46 pregnant women participated in six focus group discussions.

Participating women reported that they would change to an alternative infant feeding method if they were found to be HIV-infected and were advised to do so. Cow's milk was regarded as the most feasible infant feeding method for local HIV-infected mothers. Infant feeding formula was regarded as too costly, but if recommended by health workers and distributed free of charge, the majority of the women (82%) were confident that they would then choose this option. In the focus group discussions, women were less optimistic and expressed great concern for the social consequences of not breast-feeding. The safety of exclusive breast-feeding was questioned. Less common infant feeding methods, such as expressed heat-treated breast milk and wet-nursing, were not regarded as viable options. Several social barriers to replacement feeding were identified in the focus group discussions, including possible lack of support from partner and potential negative reactions from the community.

Future research on infant feeding options should include the broader cultural context and the psychological stress that HIV-infected women face when choosing infant feeding methods.

To examine 44-year trends in height, weight and BMI, and the prevalence of overweight/obesity and underweight in the elderly Japanese population because Japan, the country with the longest life expectancy, has the highest ageing population.

Using the nationally representative cumulative data from the Japan National Health and Nutrition Survey 1973–2016, sex-specific and age-adjusted mean height, weight and BMI, and the prevalence of overweight/obesity and underweight were calculated for each year. Trend analyses were performed using the Joinpoint Regression Program. Next, changes in height, weight and BMI, and the prevalence of overweight/obesity and underweight were estimated for each age group (65–69, 70–79 and >80 years) according to the birth year groups.

Japan.

Individuals aged ≥65 years with complete data on height and body weight measurements (N 94 508).

Trends in average height and weight increased over the four decades in both men and women. The prevalence of overweight/obesity dramatically increased and nearly tripled in men, accompanied with significantly decreased underweight prevalence. Furthermore, the increasing trend in average BMI and overweight/obesity prevalence in women reached a peak in 2002 and showed a decreasing trend thereafter, while a downward trend in underweight prevalence showed a gradual increase in women since 2003.

Trends in height, weight and BMI among the elderly population should continue to be closely monitored in parallel with the effects of dietary changes, energy intake and physical activity (step counts).

(1) To determine the extent to which an individual's childhood social circumstances and region of residence influence their dietary pattern at age 43 years and (2) to establish the extent to which an individual adopts the dietary pattern of their social and regional circumstances at age 43 years.

Longitudinal study of a social class stratified, random sample of all legitimate, singleton births in the week of 3–9 March 1946.

England, Scotland and Wales.

The 3187 survey members who provided sociodemographic information at age 4 years in 1950 and sociodemographic and dietary data (48-hour dietary recall) at 43 years in 1989.

People who remained in the non-manual social class consumed significantly higher amounts of food items correlated with the factor health aware (items include high-fibre breakfast cereals, wholemeal breads, apples and bananas) than those who remained in the manual social class. Those who made the transition from manual social class in childhood to non-manual social class at age 43 years partly adopted the distinctive dietary patterns of the non-manual social classes. Consumption of items in the factors refined (items include whole-fat milk, white bread, sugar and butter) and sandwich (items include tomatoes, lettuce, onions, bacon and ham) did not differ by social class or regional mobility.

This work suggests that although adult dietary patterns are developed as a result of childhood influences, these patterns can be modified as a result of social and regional transitions. Such changes in dietary patterns may influence susceptibility to disease.

A greater adherence to what has been labelled the Mediterranean diet is associated with a significant improvement in health status. However, it is unclear what this diet really contains. The objective of the present study is to discuss the contents of the scientific Mediterranean diet.

We argue that the evidence of the health-enhancing properties of the Mediterranean diet is not necessarily based on Mediterranean foods, and that we indeed do not have to eat Mediterranean foods to enjoy the health-promoting properties of the diet it represents. To maintain dietary variety, cultural diversity and heritage, as well as for environmental reasons, it seems more appropriate to promote regionally appropriate diets throughout the world – rather than a global Mediterranean diet.

Fe-deficiency anaemia (IDA) occurs in 1–2 % of infants in developed countries, peaks at 1–3 years of age and is associated with later cognitive deficits. The objectives of the present study were to describe the characteristics of young children with severe IDA and examine modifiable risk factors in a developed-country setting.

Two prospective samples: a national surveillance programme sample and a regional longitudinal study sample.

Canada, 2009–2011.

Two samples of young children recruited from community-based health-care practices: a national sample with severe anaemia (Hb<80 g/l) due to Fe deficiency and a regional sample with non-anaemic Fe sufficiency.

Children with severe IDA (n 201, mean Hb 55·1 g/l) experienced substantial morbidity (including developmental delay, heart failure, cerebral thrombosis) and health-care utilization (including a 42 % hospitalization rate). Compared with children with Fe sufficiency (n 597, mean Hb 122·4 g/l), children with severe IDA consumed a larger volume of cow’s milk daily (median 1065 ml v. 500 ml, P<0·001) and were more likely to be using a bottle during the day (78 % v. 43 %, OR=6·0; 95 % CI 4·0, 8·9) and also in bed (60 % v. 21 %, OR=6·5; 95 % CI 4·4, 9·5).

Severe IDA is associated with substantial morbidity and may be preventable. Three potentially modifiable feeding practices are associated with IDA: (i) cow’s milk consumption greater than 500 ml/d; (ii) daytime bottle use beyond 12 months of age; and (iii) bottle use in bed. These feeding practices should be highlighted in future recommendations for public health and primary-care practitioners.

To describe the distribution of carotenoid intakes and important food sources of carotenoids in the diet of a representative population of older Australians.

Population-based cohort study.

Two post-code areas in the Blue Mountains, west of Sydney, Australia.

We studied 2012 (86%) of the 2334 participants aged 55 + years attending the 5-year follow-up of the cross-sectional Blue Mountains Eye Study (BMES), who completed a detailed semi-quantitative food-frequency questionnaire. The intakes for five carotenoids were studied: α-carotene, β-carotene, β-cryptoxanthin, lutein and zeaxanthin combined, and lycopene.

The mean intake per day for each carotenoid was: α-carotene, 2675 μg; β-carotene equivalents, 7301 μg; β-cryptoxanthin, 299 μg; lutein and zeaxanthin, 914 μg; lycopene, 3741 μg; retinol, 653 μg; total vitamin A, 1872 μg retinol equivalents. β-Carotene equivalents contribute a substantial proportion of total vitamin A intake (65%) in this population. Women had slightly higher intakes than men for α-carotene, β-carotene equivalents, and lutein and zeaxanthin (P<0.05) . Carrots and pumpkin were the main contributors to α-carotene and β-carotene equivalent intakes. Orange juice, oranges and papaw were the main contributors to β-cryptoxanthin intake. Broccoli, green beans and oranges contributed substantially to lutein and zeaxanthin intake. The main contributors to lycopene intake were tomatoes and bolognaise sauce.

Vitamin A intake in this population is high relative to the Australian Recommended Dietary Intake. Carotenoid intakes, particularly β-carotene, make a substantial contribution, particularly from fruit and vegetables. This study provides important information as a basis for examining associations between dietary carotenoid intake and eye disease in the BMES.
