- OBJECTIVE: To characterize meal patterns in relation to obesity in Swedish women using a simple instrument describing meal frequency, meal types and temporal distribution. DESIGN: Cross-sectional parallel group design. SUBJECTS: Eighty-three obese women from the Swedish Obese Subjects (SOS) study were compared with 94 reference women, randomly recruited from the population. METHOD: A new, simplified and self-instructing questionnaire was used to assess meal patterns. Usual meal pattern was reported as time and meal type for each intake episode during a typical day. RESULTS: The obese women consumed 6.1 meals/day compared with 5.2 meals/day among the reference women (P<0.0001). All types of meals except 'drink meals' were significantly more frequently consumed in the obese group. The obese women also displayed a different meal pattern across the day, consuming a larger number of meals later in the day. As a result a larger fraction of each obese woman's total meals were consumed in the afternoon and in the evening/night. There was no difference in the number of obese vs reference women consuming breakfast. Snack meals were positively associated with total energy intake in both groups. CONCLUSIONS: A new simplified method assessing meal pattern revealed that the number of reported intake occasions across a usual day was higher in obese women compared with controls and the timing was shifted to later in the day. These findings should be considered in the treatment of obesity.

Journal article (peer-reviewed)abstract
- Department of Primary Health Care, Sahlgrenska Hospital, Göteborg University, Sweden. cecilia.bjorkelund@allmed.gu.se BACKGROUND: In Strömstad, with 10,000 inhabitants, a cardiovascular prevention program was launched during 1985-1987 because of high rates of cardiovascular disease. To study long-term effects in women, an 8-year follow-up was conducted. METHODS: Participants (n = 114) and nonparticipants (n = 269) in the lifestyle intervention program in 1985-1987 (both groups with cardiovascular risk factors) were compared regarding risk factor levels after 8 years. Effects were also compared to another community not exposed to intervention. RESULTS: After 8 years, intervention participants showed significant reduction of mean systolic blood pressure compared to the control group and had higher intake of dietary fibers and more-positive attitudes to and better knowledge of healthy diets. There was no increase of mean body weight or serum triglyceride levels whatsoever in the intervention group. Compared with another female population not exposed to intervention, body weight and systolic blood pressure changed in a significantly more favorable way. CONCLUSIONS: Results from the prevention program could be discerned after 8 years. Advantages in risk factor changes could also be found when comparing with another female population. Given the high level of stroke in women within the community, the blood pressure advantage in the intervention group is particularly encouraging. PMID: 10782370 [PubMed - indexed for MEDLINE]

Journal article (peer-reviewed)abstract
- Background/Objectives:Alcohol and dietary fat have high energy densities and may therefore be related to body weight and fat deposition. We studied associations between alcohol and macronutrient intake patterns and general and central adiposity.Subjects/Methods:A population-based cross-sectional study of 524 men and 611 women. The participants answered a dietary questionnaire describing habitual food consumption including intake of alcoholic beverages. Macronutrient intake was analysed in relation to anthropometric measures and dual energy X-ray absorptiometry determined body fat.Results:In women, total alcohol intake was negatively associated with body fat percentage (β:-0.67, P<0.01). In men, total alcohol intake was positively associated with sagittal abdominal diameter (SAD) (β: 0.28, P=0.01). In addition, positive associations were found between intake of alcohol from spirits and body fat percentage (β: 1.17, P<0.05), SAD (β: 0.52, P<0.05) and waist circumference (β: 2.29, P=0.01). In men, protein intake was positively associated with body mass index (BMI) (β: 0.03, P=0.001), body fat percentage (β: 0.04, P<0.05), SAD (β: 0.02, P=0.01) and waist circumference (β: 0.09, P<0.01). Also in men only, negative associations between fat intake and BMI (β: -0.03, P<0.01), SAD (β: -0.02, P<0.05) and waist circumference (β: -0.05, P<0.05) were found.Conclusions:Alcohol intake was inversely associated to relative body fat in women whereas spirits consumption was positively related to central and general obesity in men. Macronutrient intakes, particularly protein and fat, were differently associated with obesity indicators in men versus women. This may reflect a differential effect by gender, or differential obesity related reporting errors in men and women.European Journal of Clinical Nutrition advance online publication, 16 November 2011; doi:10.1038/ejcn.2011.189.

Journal article (peer-reviewed)abstract
- Department of Body Composition and Metabolism, Sahlgrenska Academy at Göteborg University, SE 41345 Göteborg, Sweden. lars.sjostrom@medfak.gu.se OBJECTIVE: The primary objective was to establish population-based, sex- and age-specific reference data with respect to body composition variables. Secondary objectives were to relate body mass index (BMI) to anthropometric measurements reflecting central adiposity and to body fat (BF). Another objective was to examine if secular changes in adipose tissue distribution occurred during the sampling period, 1994-1999. DESIGN: Sex- and age-specific data on anthropometric measurements and body composition were cross-sectionally collected in the reference study of Swedish Obese Subjects. SUBJECTS: In total, 1135 randomly selected subjects (524 men and 611 women), aged 37-61 y, BMI 17.6-45.4 kg/m(2). MEASUREMENTS: Measures of body fatness and fat distribution (by dual energy X-ray absorptiometry and anthropometry) were collected. RESULTS: At BMI 25 kg/m(2), relative (absolute) BF mass was 24% (19 kg) in men vs 36% (25 kg) in women, waist circumference was 90 vs 85 cm, and sagittal trunk diameter was 21 vs 19 cm. BF and measures of centralized adipose tissue distribution increased with age in both sexes (P<0.01). In women, waist circumference and sagittal diameter increased (P<0.01) over the sampling period while BMI did not. CONCLUSIONS: Sex- and age-specific reference data on body composition are reported from a randomly selected sample of Swedish men and women. At given BMIs, women had more BF but smaller waist circumference than men. Secular increases in indices of central obesity were found in women but not in men.

Dietary intake in relation to restrained eating, disinhibition, and hunger in obese and nonobese Swedish women
- 1997
-
In: Obesity Research. ; 5, s. 175-182
-
Journal article (peer-reviewed)abstract
- Department of Internal Medicine, Göteborg University, Sweden. The aims of this study were to: describe dietary intakes of obese and nonobese middle-aged women using a validated food frequency questionnaire; to assess dietary restraint, disinhibition, and hunger by the three factor eating questionnaire (TFEQ) in obese and nonobese samples and determine which of the factors are independently associated with obesity; and to examine correlations between selected nutritional variables and the TFEQ factors. Subjects studied included 179 obese Swedish women (BMI > 32) and 147 nonobese population-based controls (BMI < 28). Age-adjusted mean energy intake was significantly higher in obese women (2730 +/- 78 vs. 2025 +/- 85 kcal, p < 0.0001). In absolute and relative terms, fat intake was higher and alcohol intake was lower in the obese subjects. Disinhibition was the strongest TFEQ factor independently differentiating the obese and nonobese states, i.e., after adjustment for restraint and hunger. Within the obese sample, strong associations were seen between energy intake and disinhibition (p = 0.0005) and hunger (p = 0.0004). The association between energy intake and restrained eating was negative and weaker (p = 0.04). No such associations were seen in nonobese women. Thus, using a dietary instrument that is valid and unbiased with respect to obesity, strong psychological correlates, possibly causal, of variability in energy intake were detected in middle-aged women with obesity. Disinhibition is associated with both obesity and high-energy intakes and is therefore an important factor to consider in the treatment of women with obesity.

In: European Journal of Clinical Nutrition. ; 53, s. 375-378
-
Journal article (peer-reviewed)abstract
- Department of Internal Medicine, Sahlgrenska University Hospital, Göteborg, Sweden. OBJECTIVE: To test the validity of a dietary questionnaire which was developed with the particular goal of measuring dietary intake in obese subjects. DESIGN: Reported energy intake was compared with 24 h energy expenditure measured in a chamber for indirect calorimetry (24 EE) and reported nitrogen intake with nitrogen in urine collected during the 24 h in the chamber. SUBJECTS: Twenty-nine overweight men and women, body mass index (BMI) ranging from 25.5 49.5 kg/m2. RESULTS: Reported energy intake correlated significantly with 24 EE (r = 0.50, P = 0.006) and reported urinary nitrogen correlated significantly with urinary nitrogen excretion (r=0.56, P=0.0015). Mean reported energy intake+/-s.d. was 10.2+/-3.6 MJ and mean 24 EEi s.d. was 10.3+/-1.9 MJ. Although this difference was small and non significant, it indicates some underreporting if one can assume that these overweight subjects are less physically active in the chamber than in free-living conditions. Reported nitrogen intake also suggested underreporting at the group level. However, when the data were analysed at the individual level it was clear that the underreporting errors did not increase with increasing degree of obesity. CONCLUSIONS: Previous studies with the SOS dietary questionnaire have demonstrated that it is possible to obtain plausible energy intakes from both obese and nonobese subjects. This present analysis further demonstrates that the questionnaire discriminates overweight subjects with high and low intakes of energy and protein, using unbiased biomarkers to judge validity. These data provide additional support for the usefulness of the SOS dietary questionnaire. PMID: 10369492 [PubMed - indexed for MEDLINE]

Journal article (peer-reviewed)abstract
- Department of Internal Medicine and the Research Centre for Endocrinology and Metabolism, Sahlgrenska University Hospital, Göteborg, Sweden. Leptin is believed to play a role in regulating food intake and body weight. The aim of this study was to examine the influence of parental history of obesity on the association between baseline serum leptin concentrations and subsequent 4-y weight changes. Changes in food intake were also considered in the analysis. Middle-aged, obese women with no obese parent (n = 25) or at least one obese parent (n = 24) were included in the analysis. At baseline, women with no parental history of obesity and women with a parental history of obesity did not differ in body mass index (in kg/m2: 41.2 and 40.2, respectively) or median leptin concentrations (40.8 and 38.8 microg/L, respectively). Four-year weight changes varied widely in both groups combined (from -30 to 24 kg). Stratified regression analysis, adjusted for age, weight, and height, revealed that high leptin concentrations predicted less weight gain (or more weight loss) in women with no obese parent (beta = -21.2, P = 0.0006) but played no significant role in predicting weight gain in women with at least one obese parent (beta = -3.8, P = 0.41). Adding changes in energy and fat intakes to the model reduced the association between leptin and weight change to nonsignificance in the women with no obese parent, indicating that the effect of leptin could be explained largely by dietary changes. In conclusion, serum leptin concentrations predict long-term weight change in obese women with no history of parental obesity, an association largely mediated by changes in food intake.
