- Department of Primary Health Care, Göteborg University, Sweden. OBJECTIVE: To describe the fourth phase of the Prospective Population Study of Women in Gothenburg, Sweden, with special reference to participation and survival. DESIGN: Prospective population study. SETTING: City of Gothenburg with about 430,000 inhabitants. PARTICIPANTS: 1462 participants and 128 refusers aged 38-60 years at the time of the initial study in 1968-69, 282 women who were sampled but not invited to the study in 1968-69, and 266 women participating since 1980-81 and 32 women for the first time in 1992-93. MAIN OUTCOME MEASURES: Participation rate, survival, anthropometric and metabolic characteristics. RESULTS: The participation rate throughout the study period was high. The participants were mainly characteristic of women of the same ages in the general population even after 24 years. The mortality after 24 years was higher in non-participants than in participants, while there was no difference in survival between women who were invited and women who were not invited to the study. CONCLUSIONS: The initial participants were mainly characteristic of the general population, also after a long follow-up period. The long-term survival was lower in initial refusers than in initial participants. PMID: 9444727 [PubMed - indexed for MEDLINE]

Tidskriftsartikel (refereegranskat)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.

Low-fat diets may prevent weight gain in sedentary women: prospective observations from the population study of women in Gothenburg, Sweden

Tidskriftsartikel (refereegranskat)abstract
- Department of Primary Health Care, Göteborg University, Sweden. The Population Study of Women in Gothenburg, Sweden is an ongoing prospective study of female residents who were recruited from the local registry in 1968-1969 when they were 38-60 years old. The data presented here were collected from 361 healthy women who underwent a baseline physical examination including a supplementary dietary history interview and returned for a second general health examination 6 years later. This report identifies a subgroup of 57 women who were sedentary during their leisure time and appear to have been particularly susceptible to gaining weight as a function of the fat content of their diets. Specifically, longitudinal analysis of body weights in the whole sample revealed a statistical interaction between leisure-time physical activity and habitual dietary fat intake (energy%), as reported at the baseline examination, in the prediction of subsequent weight change. Further stratified analysis suggested that weight changes were significantly dependent on dietary fat intake among the sedentary women only. High energy intake also predicted weight gain in the sedentary group, although the predictive value for a high-fat diet was of marginal significance after adjusting for total energy consumption. These results suggest that sedentary recreational activity plus a low-fat diet may have a combined contribution to weight change that is not equivalent to the sum of the separate effects. Such a synergy between two modifiable lifestyle factors seems highly relevant for prevention of obesity. PMID: 9061715 [PubMed - indexed for MEDLINE]

Relationships between changes in body composition and changes in cardiovascular risk factors: the SOS Intervention Study. Swedish Obese Subjects
- 1997

Ingår i: Obesity Research. ; 5, s. 519-530
-
Tidskriftsartikel (refereegranskat)abstract
- Department of Medicine, University of Göteborg, Sweden. Relationships between 2-year changes in body composition (estimated from computed tomography-validated anthropometry based on sagittal trunk diameter, weight, and height), adipose tissue (AT) distribution, and cardiovascular risk factors (blood pressure, lipids, glucose, insulin, uric acid) were examined in 842 treated adults with severe obesity with weight changes from -95.5 to +30.6 kg. Although the change (delta) of visceral AT mass (expressed in % total AT) for a given change in body mass index (delta BMI) was 6-fold larger in men than in women, delta waist and delta waist/hip were similar in both sexes. In men, risk factor changes were similarly related to delta waist, delta bodyweight, and delta BMI, whereas in women, delta bodyweight seemed to be the single independent variable with the highest explanatory power. In multivariate regressions adjusted for delta BMI and baseline conditions, delta visceral AT mass was more strongly associated with risk factor changes than were delta waist and delta waist/hip. When using a three-compartment model (lean body mass, subcutaneous and visceral AT masses) plus neck and thigh girths (indicators of subcutaneous AT distribution), risk factor changes were related both to delta subcutaneous and delta visceral AT masses but not to delta lean body mass. In agreement with cross-sectional findings, delta neck was positively and delta thigh was negatively related to some risk factor changes. Thus, the use of waist as a single risk factor indicator seems less effective for epidemiological studies than the simple anthropometric measures presented here, which are able to separate the effects of visceral AT mass, subcutaneous AT mass, and subcutaneous AT distribution on metabolic parameters under both cross-sectional and longitudinal conditions.

Tidskriftsartikel (refereegranskat)abstract
- Department of Medicine, University of Göteborg, Sweden. Abnormal liver tests, as well as morphological changes in the liver, are frequent among obese patients. Other frequent disturbances are visceral fat accumulation, insulin resistance, non-insulin-dependent diabetes mellitus (NIDDM), hypertriglyceridemia, and hypertension; these are set of aberrations known as the metabolic syndrome. In order to investigate a possible relationship between the metabolic syndrome and impaired liver status we examined associations between liver tests, metabolic variables (insulin, glucose, and triglycerids), body composition and nutrition in 1,083 men (BMI 28.8-63.8 kg/m2) and 1,367 women (BMI 26.7-68.0 kg/m2) in the ongoing intervention study of Swedish Obese Subjects (SOS). Standard biochemical techniques were used to assess liver status and metabolic variables. Lean body mass (LBM) and masses of visceral and subcutaneous adipose tissue (AT) were estimated by means of computed tomography (CT) calibrated anthropometric equations. In both genders aspartate aminotransferase and alanine aminotransferase were, or tended to be, positively correlated to fasting serum insulin, visceral AT (women), and alcohol intake. In women, the aminotransferases were also correlated with fasting blood glucose. In both genders alkaline phosphatase was, or tended to be, positively associated with visceral AT, insulin (women), and glucose. Bilirubin was negatively correlated to insulin and visceral AT in men and women. Additional multivariate analyses indicated that alcohol had less explanatory power than serum insulin for the examined liver tests, especially among women. These results suggest that pathological liver tests in the obese may represent an expression of the metabolic syndrome. PMID: 9112245 [PubMed - indexed for MEDLINE]

Tidskriftsartikel (refereegranskat)abstract
- Department of Medicine, Sahlgrenska University Hospital, Göteborg, Sweden. OBJECTIVES: To determine whether 12 initial weeks on a Very Low Calorie Diet (VLCD) included in a two-year support program is associated with better long term weight loss maintenance than a dietary and behavioural support program alone. Additionally, to identify characteristics associated with successful treatment or attrition, which can be used in selecting individuals likely to respond to VLCD-programs. DESIGN: Randomised clinical trial. SETTING: Two Swedish out-patient clinics. SUBJECTS: 113 obese men and women aged 37-58 y, body mass index (BMI) > 32.0 kg/m2, participating in the Swedish Obese Subjects-(SOS) study. INTERVENTIONS: One group received VLCD for 12 initial weeks plus regular dietary and behavioural support over two years while the other group received two years of the same supportive program only. MAIN OUTCOME MEASURE: Weight loss after two years treatment. RESULTS: Both treatment groups maintained highly significant weight losses at two years but the initial VLCD-treatment appeared to have given no significant long term benefit compared to the supportive program. Examination of selected demographic, psychosocial and dietary characteristics showed that the VLCD-approach was more effective than the supportive strategy alone in men and possibly in individuals sharing household with only one person. High initial hunger-score was associated with attrition, irrespective of treatment. CONCLUSION: A VLCD-program including long term dietary and behavioural support is a successful treatment for some severely obese subjects, especially men. Further research should be directed towards matching treatments to individuals in order to improve the high recidivism rates generally following weight loss attempts.
