Evaluation of a dietary Na reduction trial in a community setting.

Community-based randomized trial. Ten-week nutrition intervention activities focused on lifestyle modification to decrease dietary Na intake, under the supervision of a registered dietitian. Twenty-four hour urine specimens were collected at baseline and follow-up visits to determine 24 h urinary Na excretion.

The University of Pittsburgh Center for Healthy Aging, Key to Life Nutrition Program.

Hypertensive adults at least 65 years of age.

Mean age of participants was 75 years. Twenty-four hour mean urinary Na excretion at baseline was 3174 mg/d. This reduced to 2944 mg/d (P = 0·30) and 2875 mg/d (P ≤ 0·03) at 6- and 12-month follow-ups, respectively. In a sub-sample (urine volume of ≥1000 ml, baseline to 12 months), mean urinary Na excretion decreased from 3220 mg/d to 2875 mg/d (P ≤ 0·02).

Significant reductions in mean 24 h urinary Na were reported, but results fell short of the recommended guidelines of 1500 mg/d for at-risk individuals. Our results reiterate the difficulty in implementing these guidelines in community-based programmes. More aggressive public health efforts, food industry support and health policy changes are needed to decrease Na levels in older adults to the recommended guidelines.

Poor oral health influences the dietary quality of older individuals. The objective of the present study was to relate the number of teeth to adherence to the 2005 Dietary Guidelines for Americans among an ethnically diverse sample of older adults.

A block cluster design was used to obtain a sample of older adults. Data were weighted to census data for ethnicity and gender. Dietary intakes were assessed using an FFQ and converted into Healthy Eating Index-2005 (HEI-2005) scores.

Two counties in North Carolina, USA, with large African-American and American Indian populations.

Community-dwelling older adults (N 635).

Three hundred and twenty-six participants had severe tooth loss (0–10 teeth remaining), compared with 305 participants with 11+ teeth. After controlling for socio-economic factors, those with 0–10 teeth had lower total HEI-2005 scores and consumed less Total Fruit, Meat and Beans, and Oils, and more energy from Solid Fat, Alcohol and Added Sugar, compared with those with 11+ teeth. Less than 1 % of those with 0–10 teeth and 4 % of those with 11+ teeth met overall HEI-2005 recommendations. Those with 0–10 teeth were less likely to eat recommended amounts of Total Vegetables, Dark Green and Orange Vegetables, and energy from Solid Fat, Alcohol and Added Sugar.

Older adults with severe tooth loss are less likely than those with moderate to low tooth loss to meet current dietary recommendations. Nutrition interventions for older adults should take oral health status into consideration and include strategies that specifically address this as a barrier to healthful eating.

To examine the prevalence of overweight and obesity in Polish adolescents in 2005 using both the International Obesity Task Force (IOTF) cut-offs and a national reference; to compare this to data collected in 1995; and to assess whether there were differences in overweight or obesity by gender and place of residence in 1995–2005.

BMI was calculated from measured height and weight, collected in a cross-sectional study in five regions of Poland in 2005. Adolescents were categorised as normal, overweight or obese based on IOTF cut-off values, and by national weight for stature tables, where the 90th and 97th percentiles were used as cut-off values for overweight and obesity.

Population-based study set in Poland.

A two-stage sampling method was used to recruit 8065 pupils (3980 boys and 4085 girls) aged 13–15 years.

The prevalence of overweight and obesity was 12·5 % and 1·9 %, respectively. No significant gender differences were found, either in overweight or obesity. The prevalence of overweight and obesity in 2005 had increased 2 % compared to 1995. Overweight and obesity among adolescents were not related to urban–rural residence, but there were significant regional differences.

Monitoring trends in overweight and obesity among adolescents in all regions of Poland using the same reference criteria is important. Since regional differences in overweight and obesity rates among adolescents were observed both in 1995 and 2005, future research should investigate the potential causes of these differences.

To assess the dietary quality of older women with and without rheumatoid arthritis (RA) using the Healthy Eating Index-2005 (HEI-2005) to identify potential strategies to improve the nutritional status.

Cross-sectional. Diet was assessed using 7 d food records and analysed for nutrient composition (Food Processor v. 7·11). Diet quality was determined using the HEI-2005, a measure of compliance with 2005 US Dietary Guidelines. Individuals with RA completed a self-reported evaluation of arthritis (pain scale and disability index). Independent two-tailed t tests or Mann–Whitney tests compared the differences between groups and correlations were computed between HEI-2005 and measures of disease reactivity.

Arizona, USA.

Older (≥ 55 years) women (n 108) with RA (n 52) and healthy controls (HC; n 56).

There were no differences between groups in age, weight, or BMI (kg/m2). HC participants had higher mean HEI-2005 scores for whole fruit (cups; P = 0·02), total fruit (cups; P = 0·05), whole grains (oz; P = 0·004), oil (g; P = 0·05) and total HEI score (P = 0·04) than the RA group. In the RA group, these same HEI components were inversely correlated with disability index (r = −0·20, P = 0·04). Participants with RA reported lower mean intakes of carbohydrate (g; P = 0·02), fibre (g; P = 0·01) and vitamin C (mg; P = 0·04).

This is the first study examining the dietary quality in older women with and without RA using the HEI-2005. Living with RA was associated with significantly lower dietary quality. Since even small changes in dietary quality can translate into better nutritional status, future interventions should focus on increasing dietary quality in this high-risk group.

To assess the relationship(s) between overall and within-food group diversity and several indices of dietary quality, such as dietary adequacy, moderation and balance, in Belgian adults. Dietary quality indices were derived from the food-based dietary guidelines (FBDG).

Information on food intake was collected with two 24 h recalls.

Average overall and within-food group diversity scores and dietary adequacy, moderation and balance scores were calculated.

A representative sample (n 3245) of the Belgian population at the age of 15 years and older was randomly selected from the National Register using a multistage stratified procedure.

For both men and women, total dietary diversity score increased with age and smokers had a significantly lower overall diversity score than non- or former smokers. A positive association was found between overall dietary diversity and both dietary adequacy and balance. For most food groups, especially bread and cereals, vegetables, dairy products and spreadable fats, within-food group dietary diversity was positively associated with the fulfilment of the specific recommendation for the intake of that food group. An inverse association was found between dietary diversity within the meat and the energy-dense, nutrient-poor food groups and dietary balance. Diversity within the dairy and spreadable fat group was responsible for the strongest increase in overall dietary adequacy and balance.

Overall dietary diversity is a useful indicator of dietary quality in Belgium. For some food groups, within-food group dietary diversity is a useful indicator of compliance with the specific FBDG for intake of that food group.

To determine how much of the variation in nutritional status of Bangladeshi children under 5 years old can be attributed to the socio-economic status of the family.

Nutritional status used reference Z-scores of weight-for-age (WAZ), height-for-age (HAZ) and weight-for-height (WHZ). A ‘possession score’ was generated based on ownership of a radio, television, bicycle, motorcycle and telephone, and the availability of electricity, with categories of 0 to 4+ possessions. A five-point (quintile) ‘poverty index’ was created using principal component analysis.

The Bangladesh Demographic and Health Survey 2004 was the source of data.

A sample of 4891 children aged <5 years was obtained.

Some 57·8 % of the sample was either stunted, wasted or underweight (7·7 % were stunted, wasted and underweight). Of those stunted (48·4 %), 25·7 % were also underweight. Underweight and wasting prevalences were 40·7 % and 14·3 %, respectively. Mean WAZ, HAZ and WHZ did not differ by sex. Children of mothers with no education or no possessions were, on average, about 1 sd more underweight and stunted than those with higher educated mothers or with 4+ possessions. The possession score provided much greater discrimination of undernutrition than the poverty index. Nearly 50 % of children from households with no possessions were stunted, wasted or underweight (only 27 % in the poorest quintile), compared with only 3–6 % of children from households with 4+ possessions (over 13 % in the richest quintile).

Maternal education and possession score were the main predictors of a child’s nutritional status. Possession score was a much better indicator of undernutrition than the poverty index.

The aim of the present study was to develop reference data for the Iranian population for anthropometric values and cardiometabolic data in comparison with those in Americans, as representative of a Western population.

The present cross-sectional survey, conducted as part of the baseline survey of a community-based interventional study (the Isfahan Healthy Heart Programme), used a two-stage clustering design and was conducted in 12 600 randomly selected adults (≥19 years of age) and 2000 adolescents (aged 11–18 years) living in three cities in the central part of Iran. For comparison with a Western population, comparable data for Americans were derived from the data sets of the Second and Third National Health and Nutrition Examination Surveys (NHANES II and NHANES III).

Iranian women had significantly higher mean BMI, waist circumference (WC), hip circumference (HC) and waist:hip ratio (WHR) than Iranian men and American women; but the mean BMI of Iranian men was lower than that of American men. The mean serum TAG level of Iranian men was significantly higher than that of Iranian women, whereas the mean serum total cholesterol (TC), LDL cholesterol (LDL-C) and HDL cholesterol (HDL-C) levels were significantly higher in Iranian women than in men. The Iranian population had lower mean TC, LDL-C and TAG levels than the Americans, but such difference was not documented for HDL-C. Iranian adolescents had significantly lower mean BMI and higher mean TAG than did American adolescents.

Our findings provide serious evidence for health professionals and policy makers about the very high prevalence of generalized and abdominal obesity in Iran. Controlling this emerging health problem, notably in women, should become a national priority in Iran and necessitates comprehensive public health programmes.

Through a literature review, we investigated the geographic information systems (GIS) methods used to define the food environment and the types of spatial measurements they generate.

Review study.

Searches were conducted in health science databases, including Medline/Pubmed, PsycINFO, Francis and GeoBase. We included studies using GIS-based measures of the food environment published up to 1 June 2008.

Twenty-nine papers were included. Two different spatial approaches were identified. The density approach quantifies the availability of food outlets using the buffer method, kernel density estimation or spatial clustering. The proximity approach assesses the distance to food outlets by measuring distances or travel times. GIS network analysis tools enable the modelling of travel time between referent addresses (home) and food outlets for a given transportation network and mode, and the assumption of travel routing behaviours. Numerous studies combined both approaches to compare food outlet spatial accessibility between different types of neighbourhoods or to investigate relationships between characteristics of the food environment and individual food behaviour.

GIS methods provide new approaches for assessing the food environment by modelling spatial accessibility to food outlets. On the basis of the available literature, it appears that only some GIS methods have been used, while other GIS methods combining availability and proximity, such as spatial interaction models, have not yet been applied to this field. Future research would also benefit from a combination of GIS methods with survey approaches to describe both spatial and social food outlet accessibility as important determinants of individual food behaviours.

Poor diet in childhood increases risk of obesity but the relationship between access to food and children’s food choice is underexplored. We determined relationships between distance to and density of food outlets on children’s food choice.

Children (n 1721) aged 9–10 years who participated in a cross-sectional study from a sample of state and private schools across urban and rural areas. Food consumption was reported using a short validated FFQ. A Geographic Information System was used to determine proximity to local food outlets. Multivariable regression analyses were performed to determine associations between food consumption and distance to and density of local food outlets.

Norfolk, England.

Boys (n 754) and girls (n 967) aged 9–10 years.

The impact of distance to or density of food outlets on food choice was small after adjustment. Living further away from a supermarket increased portions of fruit (0·11 portions/week per 1 km increase in distance to nearest supermarket, P < 0·05) and vegetables (0·11 portions/week, P < 0·05) consumed. Living closer to convenience stores was also associated with an increased consumption of crisps, chocolate and white bread. Density of supermarkets was associated with both an increase in vegetable intake (0·31 portions/week, P < 0·05) and unhealthy foods.

Distance to and density of food outlets are both associated with children’s food choice, although the impact appears to be small and the relationship is complex. However, the effects of individual foods combined could be important, particularly as even small differences in intake can impact on body weight over time.

To examine the association between breast-feeding and blood pressure, anthropometry and plasma lipid profile in both adolescence and young adulthood.

Longitudinal study of biological and behavioural risk factors for CVD.

The Young Hearts Project, Northern Ireland.

Schoolchildren aged 12 years and 15 years who participated in a cross-sectional study of lifestyle and health, and who were followed up as young adults aged 20–25 years.

There was no significant difference in height, weight, BMI, skinfold thickness measurements, blood pressure or plasma lipid profile in adolescents who had been breast-fed compared with those who had not been breast-fed. However, by the time these adolescents had reached adulthood, those who had been breast-fed were significantly taller than those who had not been breast-fed (standing height, P = 0·013; leg length, P = 0·035). Specifically, the breast-fed group was on average taller by 1·7 cm (95 % CI 0·4, 3·0 cm) and had longer legs by 1·0 cm (95 % CI 0·1, 1·9 cm). There was no significant difference in other anthropometric measures, blood pressure or plasma lipid profile in adults who had been breast-fed compared with those who had not been breast-fed.

Compared with those who had not been breast-fed, individuals who had been breast-fed were taller in adulthood. Given the known association of increased adult height with improved life expectancy, the results from the present study support a beneficial effect of breast-feeding.

To assess the adherence to the Mediterranean dietary pattern in the population from a coastal region from north-east Spain and its relationship to diseases, applying the Mediterranean Diet Quality Index (M-DQI) validated by the use of several biomarkers.

Cross-sectional nutrition survey.

Population-based random sample derived from the Catalan Nutrition Survey.

A total of 621 healthy adults.

The Catalan representative sample presented a mean M-DQI score of 6·6 (sd 2·3, median 7, range 0–14). The percentage of adherence to the Mediterranean diet was 53 %; 10 % of subjects showed high adherence to the Mediterranean diet, while only 2 % were categorized as poorest adherence. The plasma fatty acid profile of the Catalan sample progressed with perfect regularity throughout the index ranges. Both EPA and DHA presented a significant correlation to the M-DQI (r = −0·410 for EPA and −0·360 for DHA). A significant increase in palmitic, oleic and α-linolenic acids and a significant decrease in stearic, linoleic and arachidonic acids content were also observed. The mean values for the M-DQI according to the clinical characteristics of the Catalan sample were also calculated.

The M-DQI has been demonstrated a suitable tool for assessment of an individual’s nutritional status according to the Mediterranean dietary pattern and for clinical purposes. Although the current diet followed in Catalonia seems to agree with the main characteristics of the Mediterranean diet, the promotion of the Mediterranean pattern should be reinforced in the Catalan population, especially among young people.

With the upsurge in online dietary modification programmes, online dietary assessment tools are needed to capture food intake. Although the DASH (Dietary Approaches to Stop Hypertension) diet is recommended by the US Department of Agriculture, there are no online instruments that capture DASH food servings. Our objective was to assess the validity of a new, short, online dietary questionnaire developed to capture intake of DASH food servings. The DASH Online Questionnaire (OLQ) was validated against the well-known Block Food Frequency Questionnaire (FFQ).

This was a cross-sectional validation of the DASH OLQ, which contained eleven food groups (breakfast cereals; dairy; drinks; fats and oils; fruits; grains and snacks; meat, fish and poultry; mixed dishes; sweets; vegetables; and nuts, seeds and legumes). Each subject completed a DASH OLQ once weekly for four weeks and one 98.2 Block FFQ (110 questions) between weeks 2 and 4. DASH OLQ were averaged and then compared with the Block FFQ for nutrient intakes as well as intakes of DASH food groups.

Boston University Medical Center, Boston, Massachusetts.

One hundred and ninety-one faculty and staff at Boston University Medical Center aged 20–70 years.

There were significant positive correlations between the Block FFQ and the DASH OLQ for all food groups ranging from r = 0·8 for the nuts/seeds/legumes category to r = 0·3 for vegetables and mixed dishes. A comparison of nutrient intakes found strong positive correlations in all nutrient categories. Of particular interest in the DASH diet and the web-based nutrition and physical activity programme were total fat (r = 0·62), total carbohydrate (r = 0·67), total K (r = 0·68), total Ca (r = 0·69), total vitamin C (r = 0·60) and total energy intake (r = 0·68).

The DASH OLQ captures food and nutrient intake well in relation to the more established Block FFQ.

To understand more specifically how the quality, quantity and frequency of snack food consumption differs in different BMI categories.

Four hundred and forty-nine school-aged children (grade 4–6) from a Kanien’kehaka (Mohawk) community provided a 24 h recall and their height and weight in 1994, 1998 and 2002, in three independent cross-sectional samples. Food consumed between two consecutive meals was defined as a snacking occasion. ANOVA and χ2 tests were used to compare food choices between BMI categories according to food quality criteria and food groups in 2006. Logistic regression models were performed to compare results between normal-weight children and those at risk of overweight and between normal-weight and overweight children.

Energy intake from snacks tended to be higher for children at risk of overweight, compared with the other two BMI categories. Food groups with a higher energy density were also consumed more frequently by these children, with larger average portions of cereal bars (P < 0·05). Except for dessert consumption, which was less frequent among overweight children, no other variable distinguished risk of overweight in the two logistic regression models tested.

Differences detected in snack food intake between normal-weight children and children at risk of overweight could explain in part the relationship between food choices and risk of overweight. Studies of dietary differences in conjunction with body weight would benefit from considering children at risk of overweight and normal-weight children, rather than children with excess weight only.

To obtain baseline pre-intervention prevalence levels of iodine deficiency and parasitic and helminth infections in school-going children in Bie Province, Angola.

A cross-sectional study conducted in randomly selected schools. The target population was children aged 6–10 years.

Bie Province, Angola.

A total of 1029 children sampled, with 791 stool samples and 826 urine samples collected from twenty-four schools.

Widespread severe and moderate deficiencies in iodine. Children in five schools were severely iodine deficient. All sampled schoolchildren were iodine deficient to a greater or lesser extent. In all, 80 % of all children across the twenty-four schools were infected with one or a combination of intestinal helminths and intestinal protozoa.

These findings have serious implications for the cognitive development of Angolan children, as well as for Angola’s development in terms of productivity and economic potential. It is strongly recommended that the provincial and national Ministries of Health, in collaboration with international health agencies, immediately plan and implement a strategy to provide sufficient iodine through iodised oil capsules and iodised salt to the iodine-deficient population. National coalitions need to be strengthened among the government, partners and salt producers. It is also recommended that all the children in schools be de-wormed for multiple helminth species at least twice a year.

To evaluate nutritional recovery patterns in 106 undernourished children assisted by the Center of Nutritional Recovery and Education (CREN, in Portuguese) between January 1995 and December 1999.

CREN assists undernourished children aged 0 to 72 months living in the southern regions of Sao Paulo, in an outpatient setting. Nutritional status was assessed by Z-scores of weight-for-age, height-for-age and weight-for-height. Nutritional recovery evaluation considered Z-score gains in weight-for-age and height-for-age, grouping into four categories (Z-score increment of 0·50 between groups). Children with birth weight less than 2500 g were classified as low birth weight (LBW), while those born at term and with LBW were classified as small for gestational age.

CREN (Center of Nutritional Recovery and Education in Portuguese), Sao Paulo, Brazil.

One hundred and six children from CREN.

Among the 106 evaluated children, ninety-eight (92·5 %) recovered their weight or height and seventy-two (67·9 %) recovered both. Nearly half of studied children presented a nutritional recovery (increase in Z-score) of more than 0·50 in height-for-age (46·2 %) and about 40 % in weight-for-age (38·7 %). Multivariate analysis showed that treatment duration and initial weight-for-age contributed to weight-for-age Z-score increment, explaining 25 % of the variation; and treatment duration, initial height-for-age and weight-for-age Z-score increment contributed to height-for-age Z-score increment, explaining 62 % of the variation.

Our findings show that nutritional recovery among children who attended CREN was influenced primarily by the degree of nutritional deficit at admission. It has also been shown that biological variables are more important than socio-economic status in determining the rate of nutritional recovery.

The National FINDIET surveys are carried out every 5 years to monitor dietary habits and nutrient intake of the adult Finnish population. The latest survey was carried out in 2007.

Cross-sectional population-based study. Dietary assessment was carried out using 48 h recall interviews. A picture book of food portions was used to estimate portion sizes and the national Food Composition Database Fineli® to calculate nutrient intakes.

A representative sample taken in five regions in Finland.

A total of 730 men and 846 women aged 24–64 years.

The percentage contribution of fat to the total energy intake was 33 % in men and 31 % in women. The respective percentages for SFA in men and women were 13 % and 12 %, respectively, and 0·4 % for trans fatty acids in both genders. The average intakes of folate, vitamin D and fibre fell below the recommended levels, whereas the average salt intake was somewhat higher than the recommendations. Women’s diet was higher in protein, dietary fibre and sucrose compared to that of men.

According to the FINDIET 2007 Survey, the dietary habits of the adult Finnish population have headed in a positive direction overall. However, although the quality of the fats consumed has continued to improve, and the intake of salt has decreased, they still do not meet the recommended levels of intake. Similarly, the average intakes of folate and vitamin D continue to fall below the recommendations. There is also a need to increase fibre intake and to cut down the intake of sucrose.

To record the prevalence of overweight and obesity in urban primary-school children in relation to several socio-economic and demographic factors.

Cross-sectional.

A representative sample of 729 schoolchildren (379 male and 350 female), aged 9–13 years, stratified by parental educational level, was examined in the urban region of Athens. Weight and height were measured using standard procedures. The International Obesity Task Force thresholds were used for the definition of overweight and obesity. Several socio-economic and demographic data and the child’s ‘popularity’ score were also recorded with specifically designed standardized questionnaires.

The prevalence of overweight and obesity was 29·6 % and 11·1 %, respectively. Annual family income of €12 000–20 000 (OR = 1·58), residence ownership (OR = 1·63) and the grandmother as the child’s primary caregiver (OR = 1·38) were significantly associated with higher odds of childhood overweight and obesity. Non-Greek parental nationality (OR = 0·72) and higher ‘popularity’ scores of children (OR = 0·42) were significantly associated with lower odds of overweight and obesity. The grandmother as the child’s primary caregiver and an annual family income of €12 000–20 000 remained significantly associated with childhood overweight and obesity after adding all significant correlates of childhood overweight and obesity observed at the bivariate level in a multivariate regression model (OR = 1·51 and 1·61, respectively).

Among family income, residence ownership, child’s primary caregiver, parental nationality and popularity scores that were identified as significant correlates of childhood overweight and obesity at the bivariate level, lower family income and grandmother as the child’s primary caregiver were the only factors that remained significantly associated with childhood overweight and obesity at a multivariate level.

The news media are an important source of dietary information. Understanding news content, particularly the portrayal of risks and benefits of certain foods, is relevant for effective public health communication. Fish consumption may reduce risk for CVD and aid neonatal development, but recent work shows public confusion about the benefits of fish, challenged by the evidence of mercury and other contaminants in fish. We present an analysis of the messages about fish in US news media over 15 years, identifying trends in coverage and highlighting implications of current messaging.

We conducted a descriptive text analysis and coded for manifest content: locality of focus, story frame, reference to studies, inclusion of government guidelines and portrayal of uncertainty. We identified chronological patterns and analysed the data for statistically significant relationships between media source and content.

News stories were selected from five daily newspapers and five television networks (1993–2007).

We analysed 310 health-related news stories on fish.

Risk messages outweighed benefit messages four to one, and health benefits only became prominent after 2002. No difference existed in coverage topic by news source. Fish consumption has increasingly become a national issue.

With the bulk of messages about fish consumption focused on risk, the benefits may be lost to consumers. This gap creates a need for public health to work with news media to more effectively communicate benefits and risks around fish consumption and health and to consider options for communicating tailored information where it can be more readily utilised.
