“…The correlations are also similar to the results found by Blum et al (1999) among 129 children aged 1-2 y. The agreement across quartiles between the two methods obtained in our study was on average (median) 38%, which is comparable to what we have observed among adolescents and adults (Nes et al, 1992;Andersen et al, 1995Andersen et al, , 1999. When using classification into quartiles, one will expect by chance to get 25% into the same quartile and 12.5% in the opposite quartiles.…”

“…In these validation studies weighed records were also used as the reference method (7-14 days). We observed average correlation coefficients for nutrients of 0.52 among 18-y-old Norwegian adolescents (Andersen et al, 1995), and correlation coefficients of 0.59 and 0.51 among elderly women and a group of men, respectively (Nes et al, 1992;Andersen et al, 1999). The correlations are also similar to the results found by Blum et al (1999) among 129 children aged 1-2 y.…”

“…The overall aim of the survey was to provide detailed information on the current dietary habits among 12-month-old infants in Norway. The method selected for this survey was a semi-quantitative foodfrequency questionnaire (SFFQ), mainly, because we had a lot of experience using this method among adolescents and adults (Nes et al, 1992;Solvoll et al, 1993;Andersen et al, 1995Andersen et al, , 1996Andersen et al, , 1999. Furthermore, it is considered the most suitable method for assessing dietary intake in large groups.…”

Objective: To assess the validity of a semi-quantitative food-frequency questionnaire (SFFQ) used in a large nation-wide dietary survey among 12-month-old Norwegian infants. Methods: The SFFQ was administered to the parents about 1 week before the infants turned 12-month-old. The participants filled in the SFFQ and 1-2 weeks later they kept weighed food records for a total of 7 days. Both methods were completed for 64 infants. Results: The SFFQ overestimated energy intake with 25% and gave significantly higher estimates of all nutrients compared with the records, except for calcium. Much of the difference between the methods disappeared when nutrient density was compared. Spearman correlation coefficients between pairwise measurements of nutrient intakes from the food records and the SFFQ ranged from 0.18 for vitamin D to 0.72 for polyunsaturated fatty acid intake (median r ¼ 0.50). On average 38% of the infants were classified in the same quartile with the two methods, and 3% in the opposite quartile. The correlations for food items varied from 0.28 for sweetened drinks to 0.83 for commercial porridge (median r ¼ 0.62). Conclusion: This study indicated that the SFFQ overestimates average absolute nutrient intakes. However, the questionnaire gave better estimates for average nutrient densities than for absolute nutrient intakes. The capability of the questionnaire to rank infants according to intake of nutrients and food items was moderate, but at the same level as others have observed with foodfrequency questionnaires.

“…Physical activity in this context was defined as activity causing the subject to perspire and experience shortness of breath. Food and nutrient intake were estimated by a standardized quantitative food frequency questionnaire (28), and calculations were performed with use of the Norwegian Food Composition Table (29). Physical disability was measured by the Childhood Health Assessment Questionnaire (C-HAQ) and, for patients older than age 18 years, by the HAQ (30,31).…”

Objective. To determine the frequency of osteopenia in patients with childhood-onset systemic lupus erythematosus (SLE) compared with that in healthy matched controls, and to evaluate the relationship between disease-related variables and bone mineral mass.Methods. Bone mineral density (BMD) and bone mineral content (BMC) were measured in a cohort of 70 patients with childhood-onset SLE (mean ؎ SD disease duration 10.8 ؎ 8.3 years, mean ؎ SD age 26.4 ؎ 9.9 years) and 70 age-and sex-matched healthy controls. BMD and BMC of the femoral neck, lumbar spine, total body, and distal one-third of the radius were measured by dual x-ray absorptiometry. We investigated the relationship between BMC and the following disease variables: cumulative dose of corticosteroids, organ damage, current use of corticosteroids, use of cyclophosphamide, age at disease onset, and disease activity at the time of diagnosis. Biochemical markers of bone metabolism were also measured.Results. BMD values for the lumbar spine and femoral neck were significantly lower in patients than in healthy controls. The reduction in BMD of the lumbar spine was significantly greater than that of the total body. In multiple linear regression analyses, a higher cumulative corticosteroid dose was significantly associated with lower BMC of the lumbar spine and femoral neck. Decreased lumbar spine BMC was also related to male sex.Conclusion. The frequency of osteopenia was higher in patients with childhood-onset SLE than in matched controls. The lumbar spine was the most seriously affected skeletal site, followed by the femoral neck. The cumulative dose of corticosteroids was shown to be an important explanatory variable for BMC values in the lumbar spine and femoral neck.

“…A previous investigation using data from this cohort suggested that the dietary questionnaire may have resulted in the under-reporting of dietary energy intake. 11 Other studies have conversely noted an over-reporting of energy intake, 22,23 suggesting that results concerning dietary intake should be viewed with caution. Further, it is likely that crosssectional measures of dietary intake would not be the most appropriate when investigating metabolic factors in an overweight or obese population.…”

Lifecourse predictors of normal metabolic parameters in overweight and obese adults

Objective: Not all overweight and obese individuals appear to be at equal risk of developing metabolic abnormalities. We sought to examine the effect of factors from different stages of life on risk of metabolic abnormalities at age 50 years in overweight and obese adults. Design and subjects: Longitudinal study of all persons born in Newcastle upon Tyne, UK in May and June 1947 and followed to age 50 years when a clinical examination took place and a detailed questionnaire on health and lifestyle was completed. Participants in this study (n ¼ 223) were those defined as being overweight or obese with a body mass index (BMI) greater than or equal to 25 at age 50 years. Subjects were defined as 'metabolically normal' if they had normal lipids, glucose and blood pressure. Results: Lower BMI was the strongest predictor of remaining metabolically normal in both men and women. After adjusting for BMI, lower levels of cigarette smoking and higher levels of physical activity were independently associated with being metabolically normal in men. No other factors were independently associated with being metabolically normal in women. A stronger inverse relationship between BMI and metabolic status was found in men (Odds ratio (OR) per unit increase in BMI ¼ 0.65, 95% confidence intervals (95% CI) 0.52-0.81) than in women (OR ¼ 0.90, 95% CI 0.82-0.99). No association was seen for factors operating in fetal, infant and childhood life. Conclusions: Adult factors made a greater contribution to remaining metabolically normal than birth or childhood factors in this sample of overweight and obese adults. A lower adult BMI appeared to reduce the risk in men and women and lower cigarette smoking and higher level of physical activity also independently reduced the risk in men. Public health policy to reduce the burden of morbidity associated with obesity should continue to encourage weight loss, physical activity and smoking cessation.
