Healthy eating: perceptions and practice (the ASH30 study).

Perceptions of healthy eating may influence food intake. Anthropometric and dietary data were collected from 197 respondents (average age 32.5 years: 2000/2001) in Northumberland (78%) and elsewhere in the UK (22%). A questionnaire and two 3-day food diaries were completed. Foods consumed were assigned to one of five food categories from The Balance of Good Health. This paper explores respondents' concepts of 'healthy eating' and responses to the statement, 'My eating patterns are healthy' and compares responses with measured intakes for each of the five food categories. Fifty-three respondents disagreed, 62 neither agreed nor disagreed and 82 agreed with the statement. Intakes of foods containing fat and/or sugar, fruit and vegetables and meat, fish and alternatives were significantly different between the three response groups. The 'agree' group had the highest intake of fruit and vegetables and the lowest intake of foods containing fat and/or sugar and meat, fish and alternatives. A significantly higher proportion of individuals from the highest socio-economic group agreed with the statement. Significantly more individuals with Body Mass Indexes in the two lower quartiles agreed with the statement. This paper shows a relationship between perceptions of eating patterns and socio-economic status, adiposity and measured food intake.

Longitudinal change in food habits between adolescence (11-12 years) and adulthood (32-33 years): the ASH30 Study.

BACKGROUND: Links between diet in childhood and the prevention of disease in adulthood have been established. This longitudinal dietary survey provided quantitative evidence of dietary change from adolescence to adulthood, in Northumberland, England. OBJECTIVE: To report longitudinal dietary change in 198 respondents between the ages of 12 and 33 years, to explore dietary 'tracking' between the same time points and to describe the effects of gender, socio-economic status and location on dietary change. METHODS: A longitudinal study recorded dietary change from adolescence to adulthood. Two 3-day food diaries were collected in 1980 and 2000 from the same 198 respondents. Foods consumed were assigned to the five categories in the Balance of Good Health (BGH). Demographic and socio-economic information were obtained in 1980 and 2000. RESULTS: Intakes of foods containing fat and/ or sugar and milk and dairy foods decreased (p < 0.01 and p < 0.031, respectively), while intakes of fruits and vegetables increased (p < 0.01). Intakes of bread, other cereals and potatoes (p = 0.002, r = +0.219); fruits and vegetables (p < 0.01, r = +0.256) and meat, fish and alternatives (p = 0.026, r = +0.158) 'tracked' from adolescence to adulthood. Men had increased intake from meat, fish and alternatives and decreased milk and dairy foods more than female respondents (p = 0.003 and p = 0.019). Respondents who had moved away from Northumberland had a greater increase in intake of fruits and vegetables compared with those who remained in the local (p = 0.010). Individuals who had moved to a lower socio-economic group had increased their intake of bread, other cereals and potatoes (p = 0.040). CONCLUSION: Food intake changed considerably in a direction more in the line with current dietary recommendations. Food intake in adolescence was a significant, but not strong, predictor of intake in adulthood. Dietary change is influenced by variables including gender, location and socio-economic status.

Comparison of methods to estimate non-milk extrinsic sugars and their application to sugars in the diet of young adolescents.

Consistent information on the non-milk extrinsic sugars (NMES) content of foods and the NMES intake by the population is required in order to allow comparisons between dietary surveys. A critical appraisal of methods of NMES estimation was conducted to investigate whether the different published methods for estimating the NMES content of foods lead to significantly different values for the dietary intake of NMES by children and to consider the relative practicality of each method. NMES values of foods were calculated using three different published descriptions of methods of NMES estimation, and the values were compared within food groups. Dietary intake values for English children aged 11-12 years were calculated using each method and compared in terms of overall NMES intake and the contribution of different food groups to NMES intake. There was no significant difference in the dietary intake of NMES in children between the method used in the National Diet and Nutrition Surveys (NDNS) (81.9 g/d; 95 % CI 79.0, 84.7) and a method developed by the Human Nutrition Research Centre (84.3 g/d; 95 % CI 81.4, 87.2) at Newcastle University, UK, although the latter gave slightly higher values. An earlier method used by the Ministry of Agriculture, Food and Fisheries gave significantly higher values than the other two methods (102.5 g/d; 95 % CI 99.3, 105.6; P<0.05). The method used in the NDNS surveys and the method used by the Human Nutrition Research Centre at Newcastle University are both thorough and detailed methods that give consistent results. However, the method used in the NDNS surveys was more straightforward to apply in practice and is the best method for a single uniform approach to the estimation of NMES.

Longitudinal dietary change from adolescence to adulthood: perceptions, attributions and evidence.

Dietary patterns and change in eating habits are influenced by multiple factors from an individual's internal and external environment. A longitudinal dietary survey study provided quantitative evidence of dietary change and investigated factors influencing dietary change from adolescence to adulthood, using sociodemographic data and participants' own perceptions of, and attributions for, their dietary change. Longitudinal dietary data were obtained in 1980 and 2000 (average age 11.6 and 32.5 years, respectively). Two questionnaires (2000) and 2 x 3-day food diaries (1980 and 2000) were collected from 198 participants. Foods consumed were assigned to one of the five food groups from The Balance of Good Health (a UK food guide). Questionnaire responses were used to examine how subjects perceived their own dietary change and the factors to which they attributed such change. Six key factors were identified from the questionnaire: parents, partners, children, nutritional awareness, employment and lack of time. Demographic and key factors were associated with degree of change in intake. The complex process of change in food consumption can be linked with an individual's attributions for change.

Sources of dietary iron in urban and provincial 4-year-old children in Iran.

Iron-deficiency anaemia is prevalent in childhood, especially in developing countries. Nutritional deficiency is one of the main causes of iron-deficiency anaemia, although absorption varies considerably between different dietary items. Information on the sources of iron in young children is limited. A study was therefore undertaken to investigate the different dietary sources of iron in 151 healthy children aged 4 years who were selected from two districts of Fars province, Iran. Two 3-day dietary diaries with pre- and post-interview were used to record the dietary intake of the children. Food and drinks were categorised into four groups (animal, plant, drinks and other) to measure the relative importance of different sources of iron. Sixty-eight percent of the children completed the 3-day dietary diaries in both summer and winter. The results showed no statistically significant differences in total daily iron intake between the two seasons or between genders. However, the difference in the total daily iron intake between children in the city and the provincial district was significant: 7.73+/-1.75 mg/day and 10.33+/-2.9 mg/day, respectively (P < 0.001). About 75 and 60% of iron intake came from plant sources in the provincial district and city, respectively. The three most important sources of iron for children of the provincial district were bread (51%), fruit and vegetables (12%) and meat (7%). This pattern was also observed for children living in the city, but with different percentages: 27%, 16% and 16%, respectively. In conclusion, total iron intakes were similar to those recorded in European countries, but little of the intake came from animal sources and substantial differences between city and provincial children were recorded.

The relationship between acid-etch patterns and bond survival in vivo.

The aim of this study was to investigate the relationship between acid-etch quality and bond survival in vivo. The subjects were 29 orthodontic patients. High-resolution silicone impressions were taken of the buccal tooth surfaces after etching for 30 seconds with 37% phosphoric acid. The impressions were replicated in epoxy resin and examined under high magnification in a scanning electron microscope. A 4-point classification system and histometric techniques were used to evaluate etch patterns on the enamel surfaces where orthodontic brackets were to be bonded. After impressions were made, all teeth (including first molars) were bonded with 0.022-in Andrews' prescription brackets ("A" Company, San Diego, Calif) and Right-On composite (TP Orthodontics, Leeds, England). The first date of bond failure for each tooth was recorded; it varied from 1 to 806 days. An ideal etch pattern was found on less than 5% of the orthodontic bonding area; type C pattern (pitted enamel surface) occupied the greatest area. Overall, the failure rate was 55.8% over 26 months; the greatest failure rate occurred in first molars. Multiple regression analysis revealed a positive and statistically significant relationship between the area occupied by ideal etch type and the length of survival of the bond (P <.001).
